The Government is the owner of certain real and personal property, as more 16 particularly described in Article 1, commonly referred to as the former Marine Corps Air Station 17 Tustin ("MCAS Tustin") a military installation closed under the Defense Base Closure and 18 Realignment Act of 1990, Pub.L. 101-510), as amended (10 U.S.C. § 2687 note) (hereinafter 19 referred to as "DBCRA") and Lessee and Government have agreed on a method of conveyance of 20 said real and personal property as set forth in the Agreement between the United States of 21 America and the City of Tustin, California for the Conveyance of a Portion of the Former Marine 22 Corps Air Station Tustin, dated , 2002 (the "Agreement"). 23 24 B. Pending final disposition, 10 U.S.C. § 2667(f) authorizes the Government to lease 25 real property located at a military installation closed under DBCRA, in order to facilitate state or 26 local economic adjustment. Such a lease may be for consideration in an amount less than fair 27 market rental value provided the Secretary determines that such a lease will serve the public 28 interest, and that obtaining fair market rent is not compatible with such public benefit. The 29 Government has determined that this Lease will facilitate local economic adjustment efforts, that 30 the public interest will be served as a result of this Lease, and that obtaining fair market rent is 31 not compatible with such public benefit. 32 33 C. Lessee is recognized by the Secretary of Defense, through the Office of Economic 34 Adjustment, as the local redevelopment authority for MCAS Tustin. By application dated March 35 5, 1999, as subsequently amended, the City applied for a "No-Cost" Economic Development 36 Conveyance ("EDC") for portions of MCAS Tustin (the "EDC Application"), to be used and 37 developed in accordance with the "Reuse Plan for MCAS Tustin" dated October 1996 and 38 amended by Errata of September 1998 (the "Base Reuse Plan") that was reviewed and approved 39 by the United States Department of Housing and Urban Development. 40 41 D. In accordance with the National Environmental Policy Act ("NEPA") of 1969, as 42 amended, and the California Environmental Quality Act ("CEQA"), Government and the City 43 have prepared a Joint Final Environmental Impact Statement/Environmental Impact Report 44 ("EIS/EIR") for the disposal and reuse of the Former MCAS Tustin. The City certified the 03-72461.08 MCAS TUSTIN LEASE IN FURTHERANCE OF CONVEYANCE 1 EIS/EIR as complete under CEQA on January 17, 2001. A NEPA Record of Decision regarding 2 the disposal of MCAS Tustin was issued on March 2, 2001. 3 4 E. An Environmental Baseline Survey ("EBS") has been prepared for MCAS Tustin. 5 Two Findings of Suitability to Lease ("FOSLs") have also been prepared, in accordance with 10 6 U.S.C. § 2667(f)(3), and Department of Defense policy guidelines ("Finding of Suitability to 7 Lease for Southern Parcels Carve -Out Areas 1, 2, 3, and 4, Marine Corps Air Station Tustin, 8 California" dated February 28, 2002 ("FOSL No. 2" -Exhibit "C") and "Finding of Suitability to 9 Lease for Carve -Out Areas 5, 6, 7, 8, 9, 10, and 11, Marine Corps Air Station Tustin, Tustin, 10 California" dated April 26, 2002 ("FOSL No. 3" -Exhibit "D"). The FOSLs conclude that 11 activities allowed under this Lease, if conducted in accordance with the restrictions contained 12 therein, are consistent with protection of human health and the environment. Cognizant state and 13 federal regulatory agencies have concurred. 14 15 F. The Government has agreed to grant a lease in furtherance of and pending 16 conveyance by deed for portions of MCAS Tustin to the Lessee pursuant to the Agreement and 17 the Lessee has agreed to enter into this Lease. 18 19 MUTUAL UNDERSTANDINGS 20 21 NOW, THEREFORE, in consideration of the terms, covenants, and conditions 22 hereinafter set forth, Government and Lessee hereby agree as follows: 23 24 1.

Any balance of the proceeds not required for such purposes shall be paid to Government. If Government does not elect, by notice in writing to the insurer within thirty (30) calendar days after the damage or destruction occurs, to have the proceeds paid to Lessee for the purposes hereinabove set forth, then such proceeds shall be paid to Government, provided however that the insurer, after payment of any proceeds to Lessee in accordance with the policy or policies, shall have no obligation or liability with respect to the use or disposition of the proceeds. Nothing herein contained shall be construed as an obligation upon Government to repair, restore or replace Leased Premises or any part thereof. 17.4 If and to the extent required by law, Lessee shall provide workers' compensation or similar insurance in form and amounts required by law. 17.5 During the entire period this Lease shall be in effect Lessee shall require its contractors or sublessees or any contractor performing work at Lessee's or sublessee's request on Leased Premises to carry and maintain the insurance required below: 17.5.1 Comprehensive general liability insurance in an amount not less than $1,000,000 with respect to personal injury or death, and for property damage. 17.5.2 Worker's compensation or similar insurance in form and amounts required by law. 17.6 All insurance which this Lease requires Lessee or sublessee to carry and maintain or cause to be carried or maintained shall be in such form, for such periods of time, and with such insurers as Government may reasonably require or approve.

This document has been prepared by Bechtel National, Inc., on behalf of the United States Department of the Navy, Southwest Division Naval Facilities Engineering Command, in accordance with Contract Task Order -0085, issued under the Comprehensive Long -Term Environmental Action Navy Il Program Contract No. N68711 -92-D4670. This report is intended to serve as a reference document for the Department of the Navy, which is responsible for all real estate transfers and lease determinations. Information (text, figures, tables, and appendices) provided in this document is updated through 31 December 2000. However, because environmental restoration and site closure activities at WAS Tustin are ongoing, the closure status of remaining sites may change monthly as fieldwork and closure documents for sites are completed and approved. Further, since the issuance of the draft Basewide EBS Report in June 1998 (BNI 1998a), parcel designations and proposed uses for the base property have been revised to follow the Specific Plan/Reuse Plan Errata for MCAS Tustin issued in September 1998 (City of Tustin 1998). Evaluations of the selected reuse alternatives are presented in' the final Environmental Impact. Statement/ Environmental Impact Report issued in December 1999 (DON 1999a). The Environmental Impact Report portion of that document was certified by the Tustin City Council on 16 January 2001. Also, in 1999, Parcel 3 was leased to. the city of Tustin. Department of Defense and Department of the Navy policy and guidance documents, along with currently available information generated from on-site investigations, visual inspections, personnel interviews, regulatory records searches, aerial photograph reviews, reviews of data for adjacent properties, and chain -of -title searches, are the basis for this report. This Basewide EBS Report supplements the April 1994 WAS Tustin EBS for the Community Environmental Response Facilitation Act of 1992 Report (JEG 1994) and the April 1997 MCAS Tustin EBS for Parcels 6, 8B, 8C, 11A, 33, 38, 39, 41A, and 418 (BNI 1997a). MCAS Tustin was closed in July 1999 in accordance with the Base Closure and Realignment . Act. A Federal Facility Site Remediation Agreement between the Department of the Navy and the California Environmental Protection Agency Department of Toxic Substances Control (DTSC), was signed in August 1999. This legal agreement defines the Department of the Navy's corrective action and response action obligations under the Resource Conservation and Recovery Act and the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) for the 16 Installation Restoration Program (IRP) sites and 288 areas of concern (AOCs) that have been identified at MCAS Tustin. The final Site Management Plan (BNI 2000a) and the subsequent Site Management Plan -2000 Update (BNI 2000b) establish schedules and deadlines for remaining environmental restoration activities and reports. This Basewide EBS Report describes completed and planned environmental investigation and closure activities at MCAS Tustin to support reuse. Since 1993, the Base Realignment and Closure (BRAC) Cleanup Team has coordinated cleanup and closure activities at MCAS Tustin. This team consists of representatives from the Department of the Navy, the United States Final Basewide Environmental Baseline Survey, WAS Tustin page ES -1 03MM1 z:,. vw ti, w a ,os,.. VC CLEAN ii C'TO-0085/0766 Date: osn1ro1 Executive Summary Environmental Protection Agency, the California Regional Water Quality Control Board (RWQCB) Santa Ana Region, and DTSC. The BRAC Cleanup Plan Guidebook (DoD 1996a) provides the BRAC Cleanup Team with direction as to the classification of base property into one of seven area types in order to facilitate and support reuse and transfer. At MCAS Tustin, individual IRP sites, AOCs, underground storage tanks, and aboveground storage tanks are given area -type designations. The area types are ranked in order of their suitability to transfer, with Area Types 1 through 4 being suitable for transfer by deed and Area Types 5 and 6 being unsuitable for transfer by deed until all remedial actions have been completed or a remedy has been successfully. demonstrated. Areas classified as Area Type 7 either are not evaluated or require further evaluation in order to classify them into one of the other area types. The seven area types, as defined in the BRAC Cleanup Plan Guidebook, are as follows. • Area Type 1. Areas where no release or disposal of hazardous substances or petroleum products has occurred (including no migration of these substances from adjacent areas). • Area Type 2. Areas where only release or disposal of petroleum products has occurred. • Area Type 3. Areas where release of hazardous substances has occurred but at concentrations that do not require a removal or remedial action. • Area Type 4. Areas where release of hazardous substances has occurred, and all remedial actions necessary to protect human health and the environment have been taken. • Area Type 5. Areas where release of hazardous substances has occurred, and removal or remedial actions are underway, but all required remedial actions have not yet been taken. • Area Type 6. Areas where release of hazardous substances has occurred, but required actions have not yet been implemented. • Area Type 7. Areas that are not evaluated or require additional evaluation. Figures ES -1 (soil) and ES -2 (groundwater) illustrate the environmental condition of the MCAS Tustin property based on information available as of 31 December 2000. Most of the area types for sites are those initially recommended in the EBS for Community Environmental Response Facilitation Act Report (JEG 1994); however, some area types have been revised because new data became available or regulatory concurrence for no further action (NFA) was received - Additional ADCs have also been identified at the base during subsequent investigations.

As shown in Figure ES -1, a large portion of the base is suitable for transfer at this time. Of the 288 AOCs identified at MCAS Tustin, 211 (73 percent) have received regulatory concurrence for NFA and 44 (15 percent) are recommended for NFA. Of the 126 underground storage tank sites, 101 (80 percent) have received regulatory concurrence for NFA and 5 (4 percent) are recommended for NFA. Of the 25 aboveground storage tank sites identified, 11 (44 percent) have received regulatory concurrence for NFA, and 9 (36 percent) are recommended for NFA. Closure activities are continuing for the remaining AOC, underground storage tank, and aboveground storage tank sites, and it is estimated that field activities for most of the non -IRP sites will be completed during 2001. Underground Storage Tank Site 222, an RWQCB site undergoing petroleum corrective action, is the most significant of the non -IRP sites remaining to be closed. A supplemental hydrogeological characterization of the methyl tert-butyl ether. (MTBE) groundwater plume is currently being completed in preparation for interim corrective action. A Petroleum Corrective Action Program Interim Work Plan for an interim MTBE groundwater extraction/treatment system is scheduled for issuance in April 2001. Interim corrective action will focus on extracting and treating MTBE hot spots in groundwater using advanced oxidation (HiperOxidation), the recommended MTBE treatment alternative. Potential long-term corrective actions for the MTBE plume will be developed and evaluated later in 2001. Of the 16 areas initially identified as potential IRP sites at MCAS Tustin, three, IRP -2, -9 (A and B), and -15, have received BRAC Cleanup Team concurrence for NFA. IRP -13E, one third of site IRP -13, has also received concurrence for NFA. Former IRP -7 (redesignated AOC MFL-1) was transferred from the CERCLA IRP for a petroleum corrective action under RWQCB and subsequently received concurrence for NFA. IRP -4, -10, and -14 were also transferred out of the IRP and redesignated AOCs MMS -3, -4, and —5, respectively. MMS -3 subsequently received concurrence for NFA under the Resource Conservation and Recovery Act. MMS -4 and -5 have been included with IRP -5, -6, -8, -11, -13W, and -16 in Operable Unit (OU) -4 and will be closed under CERCLA once a focused feasibility study has been completed to evaluate the need for remedial action at these sites. A feasibility study has been completed for IRP -1 (OU -3). Based on recommendations in the OU -3 Feasibility Study Report, institutional controls (e.g., deed restrictions), containment wall maintenance, and long-term groundwater monitoring were identified as the preferred remedial alternative in the revised draft OU -3 Record of Decision/Remedial Action Plan issued in February 1999. The containment wall and groundwater monitoring network are already in place. A draft final Record of Decision/Remedial Action Plan for OU -3, containing institutional controls language, was issued in April 2000. Institutional controls, land -use covenant issues, and the DTSC California Environmental Quality Act evaluation are the only outstanding issues that require resolution before the OU -3 Record of Decision/Remedial Action Plan can be finalized. An OU -1 Feasibility Study Report was also prepared for IRP -3, -12, and -13S. However, subsequent to issuance of a draft final version of the OU -1 Feasibility. Study Report in.Febntary 2000, this operable unit was subdivided into OU -IA (IRP -13S) and OU -1B (IRP -3 and -12). As a result, a revised draft final OU -1B Feasibility Study Report will be issued in Spring 2001, and Final Basewide Environmental Baseline Survey, MCAS Tustin page ES -7 0341JOI 8.45 AMI do =01051SAM CLEAN II CTO -0085/0766 Date: 03121 /01 Executive Summary final remedy selection and remedial action will proceed at IRP -3 and -12, while the impact of a commingled MTBE plume on potential remedies for IRP -13S are evaluated further. OU -1A will proceed on a separate track through the feasibility study, record of decision, and remedial action process. Although long-term remedial alternatives will be implemented for some of the IRP sites, transfer of property in accordance with CERCLA Section 120(h)(3)(B) can occur sooner if the construction and installation of an approved remedial design has been completed, and the selected remedy has been demonstrated to be operating properly and successfully. The completion of final remedial design plans for OU -1B and OU -4 is currently scheduled for 2003, final remedial design for OU -IA is scheduled for completion in 2004, and long-term monitoring activities may continue through 2034. page ES -8 Final Basewide Environmental Baseline Survey, MCAS Tustin OMIJO1 8:45 AM wn L•Vwd_prooeMOgVW Wdrfl 10518AM Finding of Suitability to Lease for Southern Parcels Carve -Out Areas 1, 2, 3, and 4 Marine Corps Air Station Tustin, California w EST Dlvl Osjo .

The four areas addressed in this FOSL and proposed for a LIFOC at MCAS Tustin are Installation Restoration Program (IRP) Site 5S(b) carved from Parcels 11, 12, and 40; IRP Site 6 carved from Parcels 11, 12, 40, and 42; IRP Site 8 carved from Parcels 6, 7, 8, and 40; and the Arsenic Area of Concern (AOC) carved from Parcels 12 and 40. AOCs are investigated for possible contamination by collecting data from on-site investigations, visual inspections, personnel interviews, regulatory record searches, aerial photograph reviews, reviews of data for adjacent properties, and chain -of -title searches. The four carve -out (CO) areas pertaining to this document are referred to as "CO -1" (IRP-5S[b]), "CO -2" (IRP -6 and buffer zone), "CO -3" (IRP -8 and buffer zone), and "C04" (Arsenic AOC). The CO areas include buffer zones to allow for the protection of human health during ongoing cleanup and investigation activities. These sites and buffer zones constitute the Southern Parcels CO Areas. A Finding of Suitability to Transfer (FOST) was prepared with this FOSL to convey the portions of Parcels 6, 7, 8,11,12, and 42 that are not carved out and selected non -CO areas of Parcels 40. Several other parcels (4, 5,10,14, 25, 26, 30 through 33, 37, and portions of 41) that were not carved out are also addressed in the FOST. This FOST, known as FOST 2, was finalized on September 28, 2001. The CO areas are being excluded from the parcel conveyances because of an ongoing evaluation of impacted groundwater beneath IRP -6, and IRP -8 and continued evaluation of the IRP-5S(b) and Arsenic AOC. It is the United States Department of the Navy's (DON'S) intent that these CO areas be included in a separate FOST or similar document and be transferred once these areas have been determined to be suitable for transfer. It is anticipated that the CO property will be conveyed for commercial/ business use. Because the lease supported by this FOSL is in furtherance of conveyance, it will be in effect until the property is found suitable for transfer by deed under Section 120(h) of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), and the property is transferred by deed. The terms of the lease will be identified in the lease document. In the case where the FOSL 2, Southern Parcels CO Areas, MCAS Tustin 1 February 2002 transferee requests to have the parcels transferred prior to the completion of the environmental cleanup mentioned in this FOSL, a Finding of Suitability for Early Transfer (FOSET) will be prepared for the appropriate parcels. This FOSL was prepared in accordance with United States Department of Defense (DoD) guidance documents, including the DoD Policy on the Environmental Review Process to Reach a Finding of Suitability to Lease (DoD 1996a), which requires that a FOSL be based on an environmental baseline survey (EBS) that encompasses the property to be leased. This FOSL, including tables and figures, is based on the final Basewide EBS for MCAS Tustin Report (BNI 2001) as well as information contained in the documents listed in Attachment 1. These documents include the final MCAS Tustin Business Plan (DON 2001), which provides updated information through 31 December 2000 and schedules for planned environmental activities at the base. IRP site designations in this FOSL are consistent with those presented in the final EBS Report. Building designations and uses and parcel numbers match those presented in the final EBS Report and are consistent with those presented in the final MCAS Tustin Specific Plan/ Reuse Plan Errata (Reuse Plan) (City of Tustin 1998). Earlier environmental documents may contain different parcel designations. The MCAS Tustin environmental documents are available from the information repository located within the government document section of the main library of the University of California at Irvine. 2.0 PROPERTY DESCRIPTION MCAS Tustin is located in southern California near the center of Orange County, approximately 40 miles south of downtown Los Angeles (Figure 1). The installation encompasses approximately 1,600 acres of land. The majority of MCAS Tustin is located within the city of Tustin; about 95 acres in the southeast corner of the base are within the city of Irvine. The base is bordered by the cities of Tustin, Irvine, and Santa Ana. MCAS Tustin was commissioned in 1942 as a DON lighter -than -air base. The installation was used to support observation blimps and personnel conducting antisubmarine patrols off the coast of southern California during World War II. In 1949, the base was officially decommissioned as an active facility because of the diminished need for blimp patrols. However, in 1951, the base was reactivated to support helicopter operations for the Korean conflict and was renamed the "Marine Corps Air Station (Helicopter) Santa Ana." In 1978, the installation name was changed to "MCAS (H) Tustin" to reflect its annexation by the city of Tustin. In 1986, the installation was renamed "MCAS Tustin." MCAS Tustin was operationally closed on 02 July 1999 in accordance with the Defense Base Closure and Realignment Act of 1990. Currently, the majority of FOSL 2, Southern Parcels CO Areas, MCAS Tustin 2 February 2002 the buildings are unoccupied, and the primary activities at the installation are maintenance and environmental cleanup. The four CO areas addressed in this FOSL together comprise about 17 acres of property located in the southern and southeastern portions of WAS Tustin (Figure 2). The purpose of the CO areas is to establish boundaries wherein restrictions can be imposed to control subsurface excavation, prevent extraction and use of contaminated groundwater, prevent interference during investigation activities, allow access for monitoring and remedial activities, and prevent interference with the operation of any remediation system that may be installed on the property in the future. Approximate CO area boundaries are shown in Figure 2. Features located within the areas include: • 14 buildings/ structures (Figures 3 and 4) (a substation owned and operated by Southern California Edison is also located within the CO area boundaries); • 3 IRP sites, including IRP-5S(b), IRP -6, and IRP -8 (Figure 5); • 18 AOCs (which have all received regulatory concurrence for no further action [NFA] see Table 4), and the Arsenic AOC (Figure 6); • 2 former underground storage tanks (USTs) and 3 former aboveground storage tanks (ASTs) (which have all received regulatory concurrence for NFA) (Figure 7); and • 5 active monitoring wells (Figure 8). Information concerning the former use of the buildings and structures is in Table 1. Asbestos -containing material (ACM) and polychlorinated biphenyl (PCB) surveys were conducted in many of the buildings; survey results are summarized in Tables 2 and 3, respectively. No housing exists within the Southern Parcels CO areas. Non-residential structures have not been surveyed by DON (see Section 4.2). Summary information for the AOCs is in Table 4. Summary information for the former USTs and ASTs is in Table 5. Groundwater monitoring wells located within the CO areas are listed in Table 6. 3.0 ENVIRONMENTAL CONDITION OF THE PROPERTY The environmental restoration, environmental planning, and compliance programs at WAS Tustin have been defined and are being implemented pursuant to the following regulatory mechanisms: • CERCLA, as amended by the Superfund Amendments and Reauthorization Act and the Community Environmental Response Facilitation Act FOSL 2, Southern Parcels CO Areas, WAS Tustin 3 February 2002 • Resource Conservation and Recovery Act (RCRA) • National Environmental Policy Act (NEPA) • California Environmental Quality Act (CEQA) (as applied to City's EIR) • Petroleum Corrective Action Program • California Health and Safety Code DON is the lead federal agency regarding environmental restoration at MCAS Tustin, and the California Environmental Protection Agency Department of Toxic Substances Control (DTSC) is the lead regulatory agency providing oversight. MCAS Tustin is not listed on the National Priorities List. A Federal Facility Site Remediation Agreement (FFSRA) between DON and DTSC for MCAS Tustin was signed on 18 August 1999. The FFSRA defines DON's corrective action and response obligations under RCRA and CERCLA. Since 1993, the Base Realignment and Closure (BRAC) Cleanup Team (BCT) has coordinated cleanup and closure activities at MCAS Tustin. The BCT consists of representatives from DON, the United States Environmental Protection Agency (U.S. EPA), the Santa Ana Regional Water Quality Control Board (RWQCB), and DTSC. These agencies reviewed and commented on the required documents included in Attachment 1. Potential environmental impacts pertaining to the disposal and reuse of MCAS Tustin were addressed in the final Environmental Impact Statement (EIS)/Environmental Impact Report (EIR) (DON 1999) and were disclosed to agencies and the public for comment and review in compliance with the requirements of NEPA and CEQA. The EIS/ EIR was prepared through the joint effort of DON (EIS) and the city of Tustin (EIR). DON prepared a NEPA Record of Decision (ROD) to document the selected proposed alternative for reuse at each of the parcels discussed in the EIS/EIR. The NEPA ROD was executed on 02 March 2001 (DON 2001a). 3.1 Area Types The BRAC Cleanup Plan Guidebook (DoD 1996b) provides BCT with direction to classify base property into one of seven area types in order to facilitate and support reuse and transfer (Table 7). The area types are ranked in order of their suitability for transfer, with Area Types 1 through 4 being suitable for transfer by deed and Area Types 5 and 6 being unsuitable for transfer by deed until all remedial actions have been completed or after the remedy has been demonstrated to be operating properly and successfully. Area Types 5 and 6 may be reclassified as suitable for transfer after required remedial actions are completed and NFA concurrence has been received from BCT. Areas classified FOSL 2, Southern Parcels CO Areas, MCAS Tustin 4 February 2002 as Area Type 7 are either unevaluated or require further evaluation in order to classify them into one of the other area types. Where AOCs, USTs, or ASTs (classified as Area Types 1 through 4) lie within the boundaries of an Area Type 5 or 6 IRP site, the area -type designation depicts the environmental conditions associated with the AOC, UST, or AST rather than that of the IRP site. The AOCs in the CO areas, (except the Arsenic AOC [CO -41), are designated as Area Types 1 through 4 (Table 4). The Arsenic AOC is designated as an Area Type 7. The Arsenic AOC requires study of the surface soil to evaluate elevated arsenic levels within the CO area and will be addressed in a preliminary assessment (PA). The CO areas contain three IRP sites (IRP-5S[b], IRP -6, and IRP -8). All three sites are Area Type 6. IRP -6 and IRP -8 have NFA recommendations for soil, but are still under investigation for volatile organic compounds (VOCs) in groundwater. This VOC-contaminated groundwater plume is being addressed in the focused feasibility study (FS) Report currently being prepared for Operable Unit (OU) -4. IRP-5S(b) has an NFA recommendation for soil and groundwater, but is included in the OU -4 FS because it is one of three sites that comprise IRP -5. Further investigation of IRP -6 and IRP -8 and closure of IRP-5S(b) are anticipated when the Record of Decision (ROD) for OU4 is completed. Nineteen identified ADCs are within the CO area property (Figure 6). All, except the Arsenic AOC, have received regulatory concurrence for NFA. Regulatory NFA concurrence signature pages for the AOCs are included in Attachment 2. The Arsenic AOC is currently being evaluated (Table 4). Two USTs (251 and 252) and three ASTs (558A, 558B, and 568) were formerly located within the CO areas. All USTs and ASTs have been removed and have received regulatory concurrence for NFA. The designated area types for the AOCs, USTs, and ASTs are noted in Tables 4 and 5. The AOC locations are shown on Figure 6, and the former UST and AST locations are shown on Figure 7. Environmental conditions are described below for the CO areas. 3.2 Carve -Out Areas The purpose of the CO areas is to identify limited areas where restrictions are needed to prevent human exposure to potential contaminants while remedial action and ongoing investigations are being conducted. The approximate acreage of CO -1, CO -2, CO -3, and CO -4 are about 1 acre, 6 acres, 4 acres, and 6 acres, respectively. CO -1 includes IRP Site 5S(b) that has been recommended for NFA for soil and -- groundwater in the remedial investigation (RI). However, since IRP Site 5S(b) is a portion of IRP Site 5, closure of this site will not occur until the ROD for OU -4 FOSL 2, Southern Parcels CO Areas, MCAS Tustin 5 February 2002 is completed. Since there is no further action required based on sampling results in the RI for IRP Site 5S(b), a buffer zone beyond the site boundary is not necessary. The boundaries of CO -2 and CO -3 are the same as the boundaries of the IRP -6 and IRP -8 sites, respectively, plus buffer zones extending past the IRP site boundaries. Groundwater contamination plumes associated with these sites are currently being evaluated in the FS for OU -4. Buffer zones were developed for these carve -out areas by using the site boundaries and the areas potentially to be covered by institutional controls based on the FS for OU -4. These buffer zones may allow activities to be conducted at the buildings since the institutional controls are for groundwater. The CO -2 buffer zone is 200 feet around the estimated IRP -6 plume boundaries plus an area on the southern corner to accommodate potential downgradient plume migration and future groundwater monitoring (Figure 2). The CO -3 buffer zone extends 200 feet around the IRP -8 plume. The arsenic AOC (CO -4) boundary was based on elevated concentrations of arsenic detected in previous soil samples. Since there is not a large distribution of previous samples at this site, the buffer zone was extended to account for a larger than anticipated distribution of arsenic at the site. Legal boundaries of the site will be provided in the lease documentation. Boundaries may be redefined based on additional investigations conducted prior to lease. Restrictions will be used to control subsurface excavation, prevent extraction and use of contaminated groundwater, prevent inhalation of contaminated indoor air, prevent interference with ongoing investigation, allow access for monitoring and remedial activities, and prevent interference with the operation of remediation systems that may be installed at the sites in the future. Following are discussions of IRP-5S(b), IRP -6, IRP -8, and the Arsenic AOC. 3.2.1 IRP-5S(b) (Carve -Out -1) IRP-5S(b), Drainage Area No.1 South (Figure 5), consists of an unlined drainage ditch located in the northeast corner of Parcel 11, the eastern side of Parcel 12, and a small portion of Parcel 40. From 1956 to 1983, the ditch may have received a variety of wastes disposed in floor drains from Buildings 28 and 29 as well as runoff from other potential contaminant source areas. IRP-5S(b) is one of three sites that comprise IRP -5. IRP-5S(b) was evaluated during the site inspection (SI) conducted in 1991 (JEG 1993) and during the RI of OU -1 and OU -2 (BNI 1997). Results from sediment, soil, and surface water sampling at IRP-5S(b) indicated the presence of petroleum hydrocarbons, semivolatile organic compounds, and metals at levels above background in some of the sediment samples. Petroleum hydrocarbons were also detected in soil. No FOSL 2, Southern Parcels CO Areas, MCAS Tustin 6 February 2002 groundwater contaminants were detected above maximum contaminant levels (MCLS) . A recreational risk assessment was initially conducted during the RI for OU -1 and OU -2 (BNI 1997) since IRP -5 was classified as a jurisdictional wetland by the U.S. Army Corps of Engineers and future residential development of IRP -5 was not considered likely. The RI recommended NFA for both soil and groundwater at IRP-5S(b). At the request of the City of Tustin, a residential -scenario human - health risk assessment was subsequently conducted in order to support the possible reuse of the IRP -5 area as residential. Results from both the recreational and residential risk assessments are provided in the draft FS for OU -4 and will be used to support recommendations in the ROD. Since IRP-5S(b) is a portion of IRP -5, closure of this site will not occur until the ROD for OU -4 is completed. 3.2.2 IRP -6 (Carve -Out -2) IRP -6, the Paint Locker and Drum Storage Area (Figure 5), was operated from 1972 to 1981 and is located in the northern portion of Parcel 11, the southern portion of Parcel 12, and a portion of Parcel 40. Subsequent to this area being used for storage, Building 250 was constructed and was used as a receiving and distribution center for base supplies. The Initial Assessment Survey (IAS) conducted at the base reported that an estimated 53 gallons of wastes was released to the soil from an average of 100 drums stored at any given time (Brown and Caldwell 1985). Additionally, an estimated 225 gallons of a solution called AlodineW containing chromic acid, cyanide, and fluoride was disposed at the site. The soil and groundwater in and around this site were investigated during the Extended Site Inspection (ESI). Soil samples included detections of VOCs. PAH compounds, and metals. The predominant chemical of potential concern for groundwater was 1,1-dichloroethene (DCE). Soil and groundwater were further evaluated in the Remedial Investigation (RI). Based on the results of the RI evaluations, no further action was recommended for soil and groundwater at IRP -6. Subsequent to the RI, DON collected additional groundwater data at IRP -6. Maximum 1,1-DCE concentrations were two to three times greater than the ESI sample results and exceeded both the state and federal MCLs for drinking water. The results of the study delineated the horizontal and vertical extent of groundwater contamination at the site and are being incorporated into the focused FS Report for OU -4. The approximate location of the groundwater plume containing 1,1-DCE is shown on Figure 5. Based on these data, DON determined that groundwater at the site should be evaluated as part of the same focused FS for OU -4 that also includes IRP-5S(b) and IRP -8. FOSL 2, Southern Parcels CO Areas, WAS Tustin 7 February 2002 3.2.3 IRP -8 (Carve -Out -3) IRP -8, Drainage Area No. 2 (Figure 5), is located in the eastern portion of Parcel 7 and in a portion of Parcel 40. No. 2 diesel fuel from this area, used to.supply power generators, was reportedly spilled or leaked to a nearby unlined storm drainage ditch from 1976 to 1984. Soil gas, soil, and groundwater samples were collected at the site during the SI and ESI. The predominant chemicals reported at the site were VOCs, PAHs, and metals. Some VOC concentrations were found to exceed MCLs for drinking water. The primary chemical of potential concern for IRP -8 identified during the ESI was 1,2-dichloropropane in groundwater. Groundwater at IRP -8 was further evaluated during the RI. Based on the results of the RI evaluations, no further action was recommended for soil and groundwater at IRP -8. Subsequent to the RI, DON reviewed the groundwater data for IRP -8 and determined that groundwater at the site should be evaluated further because the maximum concentration of 1,2-DCP exceeded MCLs for drinking water. The evaluation is being performed by means of the same focused FS for OU -4 that includes IRP-5S(b) and IRP -6. 3.2.4 Arsenic Area of Concern (Carve -Out -4) The Arsenic AOC was identified during investigations at three ADCs (ST -86, ST - 88, and MAE-03) located in the southeastern portion of the base. Sampling was conducted at the three AOCs to detect any COCs associated with the historical activities conducted at these sites. During the confirmation sampling phase of the remedial actions for these sites, elevated levels of arsenic were detected in the surface soil that exceeded the predetermined arsenic background level of 17.5 milligrams per kilogram. Arsenic is not considered a COC for any of the three sites; therefore, a new AOC (the Arsenic AOC) was established to investigate the potential source of the arsenic in the surface soil in the area. A PA of the Arsenic AOC is currently being conducted. The PA will include assessing potential sources by investigating historical activities in the area. Based on the results of the initial assessment, sampling will be conducted to supplement the arsenic results from previous investigations in the area. After additional arsenic data are collected, a risk assessment will be conducted to determine whether further action is required at the site. The boundary of the CO area is that of the Arsenic AOC, which contains areas where elevated levels of arsenic have been detected and an adequate buffer zone to complete the investigation at the site. The elevated levels of arsenic have been detected in the northeastern and northwestern corners of Building 190 and on the northern border of Building 251. FOSL 2, Southern Parcels CO Areas, MCAS Tustin 8 February 2002 4.0 RESTRICTIONS AND NOTIFICATIONS The environmental documents listed in Attachment 1 (References) were evaluated to identify environmental factors that may warrant constraints on certain activities to assure that the intended use of the parcels is protective of human health and the environment. The factors that require notifications and/or restrictions are discussed below. See Table 8 for a list of environmental factors considered. Lease restrictions are summarized in Section 5. Notification will be provided to the lessee by attaching a copy of this FOSL to the lease. Attachment 5 contains comments from regulatory agencies and other interested parties with DON's corresponding responses. There were no unresolved comments from DTSC on this FOSL. 4.1 Restrictions - Indoor Air Quality Based on the air pathway results included in the draft OU -4 FS for IRP-5S(b), contaminated soils located in and around the drainage ditch for IRP-5S(b) are not anticipated to impact air quality. At IRP -6 and IRP -8, soil conditions have been recommended for NFA in the RI; however, the potential still exists for indoor air to be impacted from the associated groundwater plumes. Since no data has been collected on indoor air within buildings potentially impacted by adjacent IRP sites 6 and 8, Buildings 219, 556, and 250 shall be restricted from occupation. "Occupation"includes access in the vicinity of the buildings, with the exception of short-term tours and emergency maintenance with prior DON notification and approval. To remove this restriction, the lessee may conduct air monitoring within the building following all federal, state, and local requirements, to determine the suitability of use of a particular building. Removal of this use restriction based on indoor air will be determined by the review and approval of DON and the BCT of the indoor air report submitted by the lessee, or upon DON and BCT concurrence that restrictions for indoor air quality are no longer necessary. 4.2 Notifications and Restrictions - Lead -Based Paint In order to address the risk of adverse health effects to children from LBP ingestion and exposure, legislation and national policy regarding LBP has focused on residential areas and child -occupied facilities where children may be present. Non-residential buildings (e.g., warehouses and office buildings) are typically occupied by adults with minimal exposure to children. DON policy regarding LBP applies to residential real property constructed before 1978. None of the buildings/ structures on the CO area property have been designated for residential property or child -occupied facilities under the Reuse Plan; therefore, they have not been surveyed for LBP. DON will not conduct sampling at non- residential buildings prior to leasing the property. Any evaluation and FOSL 2, Southern Parcels CO Areas, MCAS Tustin 9 February 2002 abatement of LBP at non-residential buildings will be the responsibility of the lessee. Non-residential buildings scheduled for demolition will require post -demolition soil sampling and abatement of any soil -lead hazards by the lessee prior to occupancy of any newly constructed buildings. Buildings that are scheduled for demolition may be occupied on an interim basis if the lessee conducts the necessary LBP surveys and abatement in accordance with all local, state, and federal requirements. Information pertaining to LBP at non-residential buildings, if any, will be provided to the lessee with the lease documents. Notification of potential LBP at non-residential buildings where surveys were not conducted will be based solely on the age of construction (i.e., constructed before 1978). The Southern Parcels CO areas do not contain any residential property. If any buildings are to be used for residential purposes during the lease, the lessee must obtain prior approval from DON and the BCT. 4.2.1 Notifications Building 190 was built in 1970 and is located in Parcel 12 and the disposition of the property is still to be determined. Based on the age of construction, lead- based paint may have been previously used on this building. Building 212 was built in 1972 and is located in Parcel 7 and the disposition of the property is still to be determined. Based on the age of construction, lead-based paint may have been previously used on this building. Building 219 was built in 1976 and is located in Parcel 7 and is scheduled for demolition. Based on the age of construction, lead-based paint may have been previously used on this building. Building 267 was built in 1984 and is located in Parcel 11 and is scheduled for demolition. Based on the age of construction, it is unlikely that LBP was used at this building. Building 556 was built in 1990 and is located in Parcel 11 and is scheduled for demolition. Based on the age of construction, it is unlikely that LBP was used at this building. Building 250 was built in 1984 and is located in Parcels 11,12 and 40 and is scheduled for reuse. Based on the age of construction, it is unlikely that LBP was used at this building. Building 251 was built in 1984 and is located in Parcel 12 and is scheduled for reuse. Based on the age of construction, it is unlikely that LBP was used at this building. FOSL 2, Southern Parcels CO Areas, MCAS Tustin 10 February 2002 All seven structures (251A, 252, 269, 555, 560, 585, and 593) were constructed after 1978 and are located in Parcels 7 and 12. Based on the age of construction, it is unlikely that LBP was used at these structures. 4.2.2 Restrictions Buildings 190 and 212 Since these buildings were constructed prior to 1978 and have a property use designation of 'to be determined', use of these buildings is restricted from residential use and children will not occupy these buildings. However, if the lessee conducts the necessary LBP surveys and abatement in accordance with all local, state, and federal requirements to ensure the safety of occupants for residential use, the buildings can be used for residential use after receiving concurrence from DON and the BCT on the LBP reports. If the buildings are slated for demolition, they will require post -demolition soil sampling and abatement of any soil -lead hazards by the lessee prior to occupation of any new buildings. Building 219 Since this building was constructed prior to 1978 and is scheduled for demolition, residential use is restricted and children will not occupy this building. The lessee must obtain approval from DON and the BCT to use this building for residential use or for the occupation of children. Furthermore, the lessee will be responsible for conducting post -demolition sampling of the soil and conduct any required abatement prior to occupancy of newly constructed buildings. Buildings 267, 556, 250, and 251 Since these buildings were constructed after 1978, no restrictions or requirements are necessary for LBP. All seven structures (251A, 252, 269, 555, 560, 585, and 593) Since these structures were constructed after 1978, no restrictions or requirements are necessary for LBP. 4.3 Notification - Polychlorinated Biphenyls An inventory of PCB items and equipment was conducted in 1992 (Kennedy/Jenks Consultants 1992). Twenty-two items were identified as possibly containing PCB insulation fluid. With the exception of one item located off base, these items have been replaced, or tested and found not to contain PCB fluids or insulation. Fluorescent light fixtures were not included in the PCB items and equipment survey. Because Buildings 190, 212, and 219 were built before 1979, it is assumed that some light ballasts in the buildings may contain PCBs. Fluorescent light ballasts manufactured before 1979 often -contain PCB small capacitors that may be disposed as municipal solid waste. No action is required at the buildings unless large quantities of PCB -containing fluorescent light ballasts are removed. FOSL 2, southern Parcels CO Areas, MCAS Tustin 11 February 2002 According to DON guidance on disposal of fluorescent light ballasts containing PCBs (DON 1989), large quantities of PCB small capacitors generated from fluorescent light ballasts, such as when the fixtures in a large office or an entire building are replaced, should be disposed as regulated PCB equipment. Fluorescent light ballasts that contain PCBs have approximately 1.0 to 1.5 ounces of PCB fluid in each capacitor. For this given quantity, there would be approximately 3.1 to 4.7 pounds of PCB fluid for every 50 PCB small capacitors in fluorescent light ballasts. If the lessee plans to dispose fluorescent light ballasts containing more than 3 pounds of PCB fluid, the PCB small capacitors in those light ballasts should be processed as regulated items. In 1996 a PCB transformer survey was conducted at MCAS Tustin (PWC 1996). Per DON policy, transformers containing PCBs at concentrations exceeding 50 parts per million (ppm) were replaced. Transformers with PCB concentrations less than 50 ppm are classified by federal standards as non -PCB transformers. Two buildings in Southern Parcels CO Areas property, Buildings 250 and 556, had associated transformers located at Structure SS -2 (Table 3). Transformers were also associated with Buildings 190 and 251. These transformers contained PCBs at concentrations of less than or equal to 2 ppm; therefore, these were not replaced. 4.4 Notification - Radon DoD policy is to disclose all available and relevant radon assessment data pertaining to BRAC property being leased or transferred, and to include this data in property lease documents. There is currently no federal requirement to perform additional radon assessment or mitigation in federal buildings, including those to be transferred to the public or private sector (DoD 1994). Though not required by regulatory agencies, DON conducted a radon survey at a representative number of housing units and non-residential buildings at MCAS Tustin in 1991. Radon screening results were based on a representative sampling of structures. The results indicated that none of the facilities or housing units contained levels of radon above 4 picocuries per liter (pCi/L). According to U.S. EPA guidance, radon at levels of 4 pCi/ L or less are considered "low risk," and no mitigation is required (Bufton 1991). Additional radon testing or mitigation, therefore, was not required. 4.5 Notification - Wetlands IRP-5S(b) is a drainage facility that has been designated as jurisdictional waters of the United States under Section 404 of the Clean Water Act. The United States Army Corps of Engineers exerts jurisdiction over waters of the United States, which include territorial seas, tidal waters, and nontidal waters. IRP-5S(b) FOSL 2, Southern Parcels CO Areas, MCAS Tustin 12 February 2002 supports cattail and other common marsh vegetation. The water source appears to be urban and agricultural runoff from both on-site and off-site sources. Development by the lessee in wetland areas will require Section 404 permit(s) (DON 1999). 4.6 Notifications and Restrictions - Hazardous Substances and Petroleum Products Past activities within the Southern Parcels CO Areas included the use and storage of hazardous substances and petroleum products. Releases of contaminants have occurred during these activities. IRP-5S(b), IRP -6, IRP -8, and the Arsenic AOC have not received regulatory closure and are currently being evaluated. Information concerning contaminants associated with the IRP sites in the CO areas is provided in Section 3.0 of this FOSL. The lessee will be required to obtain DON and BCT approval before performing any subsurface excavation, digging, drilling, or other soil disturbance, or using groundwater within the CO areas. 4.7 Notifications and Restrictions - Areas of Concern The following summarizes notifications and restrictions that are required because AOCs are on the CO area property. 4.7.1 Notifications Summary information for the 19 AOCs that are located within the CO area property is presented in Table 4. The AOC locations are shown on Figure 6. With the exception of the Arsenic AOC, all of the AOCs have received regulatory concurrence for NFA. A discussion of the Arsenic AOC is included in Section 3.2.4. 4.7.2 Restrictions Use of the Arsenic AOC (CO -4), including subsurface excavation, digging, drilling, or other soil disturbance, or using groundwater, will require prior DON and BCT approval. Removal of this use restriction based on arsenic will be determined upon DON and BCT concurrence that restrictions for arsenic are no longer necessary. 4.8 Notifications and Restrictions - Radiological Materials The following summarizes notifications and restrictions that are required due to the potential use or storage of radiological materials in and around buildings located within the CO area property. FOSL 2, Southern Parcels CO Areas, MCAS Tustin 13 February 2002 4.8.1 Notifications A historical radiological assessment (HRA) (Roy F. Weston 2000) was conducted at MCAS Tustin. The purpose of the assessment was to identify buildings where potential past or present use of radiological materials may have occurred and recommend those buildings for a radiological survey. On the basis of the assessment, Buildings 190 (Parcel 12) and 556 (Parcel 11) will be investigated further in a radiological survey. Building 190 is a hangar where operating aircraft that used radioactive equipment were located during maintenance activities. Building 556 was investigated during the HRA because radioactive material was reportedly stored in and adjacent to this building in 1998 and 1999 while ship -out arrangements were being made before base closure. Specifically, the following items were investigated during the HRA. • Inside Building 190, the former helicopter maintenance area was investigated. Radioactive in-flight blade inspection systems and ice detector units with radioactive material were reportedly present in the helicopters that had previously been maintained in the building. • Inside Building 556, a 55 -gallon drum containing radioactive components (i.e., 12 ice detectors and 2 radiation detection meters) was investigated. This drum was stored in a locked storage room. • Outside Building 556,11 drums containing aluminum oxide sand blast grit were investigated. The sand blast grit contained detectable, although exempt, quantities of naturally occurring radium and thorium. The grit was reportedly never used for blasting of aircraft at MCAS Tustin because of its high abrasive characteristics. The ice detector units, radiation detection meters, and sand blast grit were removed in June 1999. DON will perform a radiological survey inside Buildings 190 and 556, and in the adjacent drum storage area outside of Building 556 to determine whether these buildings can be released for unrestricted use or whether institutional controls are necessary. 4.8.2 RESTRICTIONS Buildings 190, 556, and the drum storage area adjacent to Building 556 will be prohibited from access pending the results of the radiological survey. Based on the survey results, DON will evaluate whether to release the buildings from this restriction. The survey results must also be approved by the regulatory agencies before the buildings are released for access under the lease. If a building is FOSL 2, Southern Parcels CO Areas, MCAS Tustin 14 February 2002 released, a Lease Restriction Revision Form (Attachment 3) will be completed to allow access to the building under the Southern Parcels CO Areas property lease. 4.9 Notifications and Restrictions - Asbestos -Containing Material DoD policy with regard to asbestos -containing material is to manage ACM in a manner protective of human health and the environment, and to comply with all applicable federal, state, and local laws and regulations governing ACM hazards. Therefore, unless it is determined by competent authority that the ACM in the property poses a threat to human health at the time of transfer, all property containing ACM will be conveyed, leased or otherwise conveyed as is through the BRAC process (DoD 1994). ACM is considered to be a threat to human health if it is located within the interior of a building, and it is friable, accessible and damaged (FAD). Prior to property disposal, all available information on the existence, extent, and condition of ACM shall be incorporated into the Environmental Baseline Survey (EBS) report or other appropriate document to be provided to the lessee. The survey report or document shall include: Reasonably available information on the type, location, and condition of asbestos in any building or improvement on the property; Any results of testing for asbestos; 0 A description of any asbestos control measures taken for the property; • Any available information on costs or time necessary to remove all or any portion of the remaining ACM; however, special studies or tests to obtain this material are not required; and Results of a site-specific FAD ACM survey performed to revalidate the condition of the ACM. However, the DON is required to conduct a FAD ACM survey only when the reuse plan calls for a building to be reused/ occupied, rather than demolished. Furthermore, a FAD ACM survey is not required if ACM has never been identified in the interior of a building during any previous asbestos survey, or if an asbestos survey conducted after 1996 found no damaged ACM and there is no reason to suspect any damaged ACM is present. The 1996 date was established to be consistent with the Asbestos Hazard Emergency Response Act (AHERA), which calls for a re -inspection to assess the physical condition (i.e., good or damaged) of ACM at least once every three years. Since base closure occurred in 1999, any qualified inspection performed in 1997 or later meets the intent of these regulations. Asbestos -containing material shall be remediated prior to property disposal only if it is of a type and condition that is not in compliance with applicable laws, FOSL 2, Southern Parcels CO Areas, MCAS Tustin 15 February 2002 regulations, and standards, or if it poses a threat to human health at the time of transfer of the property (i.e., FAD ACM). This remediation should be accomplished by the DON or by the lessee under a negotiated requirement of the property lease. Use of such buildings must be restricted until abatement has been completed. The remediation discussed above will not be required when the buildings are scheduled for demolition by the lessee; the lease document prohibits occupation of the buildings prior to the demolition; and the lessee assumes responsibility for the management of any ACM in accordance with applicable laws. Buildings, which are to be demolished, may be occupied on an interim basis if the lessee conducts the necessary ACM surveys and abatement according to all local, state, and federal requirements. A graphical representation of this policy and the decision-making process is presented as Figure 9. The following summarizes notifications and restrictions that are required due to the reported presence of ACM in some of the buildings located on the CO area property. 4.9.1 Notifications Three ACM surveys conducted at MCAS Tustin included buildings in the Southern Parcels CO Areas, and the survey results were presented in reports dated December 1988, December 1991, and January 2001 (IT Corporation 1988, Ecology and Environment, Inc. 1991; URS 2001, respectively). The January 2001 survey was limited to FAD ACM. Results from the ACM surveys are summarized in Table 2. To assure full disclosure of all ACM on the parcels, copies of the ACM survey reports will be included in the lease documentation. 4.9.1.1 Buildings Planned for Demolition or "To Be Determined (TBD)" Building 190 was built in 1970 and is located in Parcel 12. The 1991 asbestos survey reported numerous types of non -friable ACM. The 2001 survey reported FAD ACM. See Table 2 for a description. Building 212 was built in 1972 and is located in Parcel 7. The 1988 asbestos survey reported friable damaged ACM (ceiling tile). However, the January 2001 survey reported no FAD ACM in the building. Building 219 was built in 1976 and is located in Parcel 7. The 1991 asbestos survey reported no ACM in the building. Building 267 was built in 1984 and is located in Parcel 11. This building has never been surveyed. FOSL 2, Southern Parcels CO Areas, MCAS Tustin 16 February 2002 Building 556 was built in 1990 and is located in Parcel 11. This building has never been surveyed. 4.9.1.2 Buildings Planned for Reuse Building 250 was built in 1984 and is located in Parcels 11,12 and 40. This building had never been inspected for asbestos during the operational life of the base. Since this building was specified as being reused, the DON conducted a FAD ACM survey pursuant to DoD policy. The revalidation survey to identify FAD ACM was conducted in Building 250 in January 2001 (URS 2001). No FAD ACM was identified in the building. Building 251 was built in 1984 and is located in Parcel 12. This building had never been inspected for asbestos during the operational life of the base. Since this building was specified as being reused, the DON conducted a FAD ACM survey pursuant to DoD policy. The revalidation survey to identify FAD ACM was conducted in Building 251 in January 2001 (URS 2001). No FAD ACM was identified in the building. 4.9.2 Restrictions Building 190 - Since FAD ACM was observed in this building, it will be restricted from occupancy, and the lease will indicate that if the lessee chooses to occupy the building on an interim basis, the lessee assumes responsibility for the management of ACM in accordance with applicable laws. "Occupation" includes access in the vicinity of the buildings, with the exception of short-term tours and emergency maintenance with prior DON notification and approval. This building may be occupied if the lessee conducts the necessary ACM surveys and abatement according to all local, state, and federal requirements. Buildings 267 and 556 - Since no ACM surveys have been conducted at these buildings, they are restricted from occupancy prior to demolition. This building may be occupied if the lessee conducts the necessary ACM surveys and abatement according to all local, state, and federal requirements. Buildings 212, 250 and 251 - Since no FAD ACM was found in these buildings, they may be leased without restrictions for occupancy due to ACM. However, the lessee must still assume responsibility for the management of ACM, if any. Building 219 - Since no ACM was observed in this building and it is scheduled for demolition, this building may be leased without restrictions for occupancy due to ACM. However, the lessee must still assume responsibility for the management of the existing ACM, if any. FOSL 2, Southern Parcels CO Areas, MCAS Tustin 17 February 2002 4.10 Notifications and Restrictions - Groundwater Use/Subsurface Excavation The following summarizes required notifications and restrictions relating to groundwater use and subsurface excavation within the CO area property. 4.10.1 Notifications As noted in Section 3.1, VOC-contaminated groundwater exists beneath IRP -6 and IRP -8, and arsenic -in -soil impacts in the Arsenic AOC are currently being evaluated. 4.10.2 Restrictions To address potential risks associated with environmental factors at CO -1, CO -2, CO -3, and CO -4 the lessee cannot excavate, dig, drill, or otherwise disturb soil and extract or use groundwater beneath these areas without obtaining prior DON and BCT approval. Until remedial activities at CO -1, CO -2, CO -3, and CO -4 are completed and regulatory concurrence for no further action is achieved, the lessee may not conduct construction projects without prior approval from DON and the BCT. The lessee must demonstrate to DON and the BCT that these activities will not interfere with or adversely affect DON response action(s) for the IRP sites and/or the Arsenic AOC and that human health and the environment will be adequately protected. No activities will be conducted until written approval is obtained from DON and the BCT. Removal of this use restriction based on groundwater and soil contamination will be determined upon DON and BCT concurrence that restrictions for groundwater use and subsurface excavation are no longer necessary. 5.0 SUMMARY OF RESTRICTIONS The prospective lessee will be required to comply with all environmental provisions. Following are some of the environmental provisions that apply to this FOSL (a complete summary of notifications and restrictions is shown in Table 9). • Buildings 219, 556, and 250 will be restricted from occupancy unless appropriate air monitoring within the buildings is conducted by the lessee and the results are reviewed and approved by DON and the BCT (Section 4.1). • Buildings 190 and 212 will be restricted from residential use and children will not occupy these buildings unless the necessary LBP FOSL 2, Southern Parcels CO Areas, WAS Tustin 18 February 2002 • Buildings 190 and 212 will be restricted from residential use and children will not occupy these buildings unless the necessary LBP surveys and abatement is performed and approved by DON and the BCT (Section 4.2.2). • Building 219 will be restricted from use prior to demolition and the lessee will conduct post -demolition sampling of the soil and conduct any required LBP abatement prior to occupancy of newly constructed buildings (Section 4.2.2). The aluminum shed adjacent to building 219 will not be restricted due to LBP because it is unpainted. • Subsurface excavation, digging, drilling, or otherwise disturbing the soil and extracting or using groundwater will be restricted within the CO area property, which includes IRP-5S(b), IRP -6, IRP - 8, and Arsenic AOC, unless prior approval for such activities is obtained by the lessee from DON and the BCT (Sections 4.6, 4.7.2, and 4.10.2). • Buildings 190, 556, and the drum storage area will be prohibited from access pending the results of the radiological survey and the .completion of any necessary response action by DON (Section Because FAD ACM is present, Building 190 will be restricted from occupancy -during the lease period unless abatement is completed by the lessee (Section 4.9.2). Buildings 190, 267, and 556 will be restricted from occupancy unless necessary ACM surveys and abatement are completed (Section 4.9.2). The lease will include an easement section that will generally describe easements and rights of access for the duration of the lease. Southern California Edison substation SS -2 on Parcel 11 will be located on an easement. 6.0 REGULATORY COORDINATION U.S. EPA, DTSC, and the Santa Ana RWQCB were notified of the initiation of this FOSL and were issued copies for review. 7.0 NOTICE OF HAZARDOUS SUBSTANCES Pursuant to CERCLA Section 120(h)(3)(A)(i) and the provisions of 40 Code of Federal Regulations Part 373, preparation of a notice of hazardous substances stored, released, or disposed within the parcels at MCAS Tustin is required for transfer of the parcels. The Hazardous Substance Notification Table and FOSL 2, Southern Parcels CO Areas, MCAS Tustin 19 February 2002 a', Date: UST/ AST Substance Notification Table are provided in Attachment 4. The UST/ AST Substance Notification Table lists the UST/ AST sites (containing petroleum products), which are within the scope of the CERCLA Petroleum Exclusion set forth in CERCLA Section 101(14). RIGHT OF ACCESS The lease will contain appropriate provisions reserving access to the property for DON and regulatory agency personnel to conduct investigations, surveys, sampling, monitoring, and remedial action activities. Access to monitoring wells I006MW02S (Parcel 40), and I006MW01S, I006MW01 D, I006MW03S, and I006MW04S (Parcel 11), used for quarterly water -level measurements, will be required after the lease expires and the property is conveyed (Figure 8). A summary of the monitoring activities is included in Table 6. CONCLUSIONS/FINDING OF SUITABILITY TO LEASE IN FURTHERANCE OF CONVEYANCE Based on the foregoing information and analysis, I find that the property identified in this FOSL (Southern Parcels CO Areas) is suitable for lease for the purposes intended, subject to the conditions, notifications, and restrictions set forth in this document. The property can be used pursuant to the proposed lease, with the specified use restrictions in the lease, with acceptable risk to human health and the environment and without interference with the environmental restoration process. 2 I PAtR.

Hickox gericy Secretary California Environmental Protection Agency Depaftment of Toxic Substances Control February 27, 2002 Edwin F. Lowry, Director 5796 Corporate Avenue Cypress, California 90630 Mr. Keith S. Forman BRAC Environmental Coordinator Naval Facilities Engineering Command BRAC Program Office 1230 Columbia Street, Suite 1100 San Diego, California 92101-8517 P. 02/04 FINDING OF SUITABILITY TO LEASE (FOSL) FOR SOUTHERN PARCELS CARVE OUT (CO) AREAS 1, 2, 3, AND 4, MARINE CORPS AIR STATION (MCAS) TUSTIN, CALIFORNIA Dear Mr. Forman: Gray Davis Governor On January 23, 2002 the Department of Toxic Substances Control (DTSC) received the subject document dated January 2002. DTSC reviewed the document and had some additional comments. Based upon review of specific revised text, tables and figures, the additional comments have been- appropriately addressed.Based on DTSC's review of the information presented in the document and the subsequent changes, DTSC concurs that the Southern Parcels CO Areas property is suitable for lease for the purposes intended (commercial/business) subject to the conditions, notifications, and restrictions set forth in the FOSL. There are three buildings (190 [CO Area 4], 212 and 219 [CO Area 3]) located on the CO Area property which were constructed prior to 1978, the year when lead-based paint (LBP) products were discontinued. Based on the age of construction, LBP may be present on these buildings. The buildings and the surrounding environment are designated for commercial/business use where children will be restricted from occupying any of the buildings. Exposure to soil is also limited in these areas because Building 190 is completely surrounded by concrete and Building 212 is completely surrounded by concrete/asphalt. The designation of Building 219 includes one building and one structure (an unpainted aluminum shed). The LBP issue is only related to Building 219 and not its associated structure. Building 219 is surrounded by concrete The energy challenge lacing California is real. Every Cslifomian needs to take immediate sctyon to reduce energy consumption.

Due to the designated reuse of the property and the site conditions. DTSC is confident that all three buildings and the surrounding environment can be leased, with the appropriate restrictions, in a manner that is protective of human health and the environment. However, if the designated land use changes from commercial/business to a more sensitive use (i.e., residential), DTSC would have to reevaluate its decision to concur on CO Areas 3 and 4 for lease. Although DTSC is concurring on this FOSL, LBP may be an issue for the future transfer of CO Areas 3 and 4. DTSC maintains that any lead released to soil from LBP is a Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) release to the environment. The surfaces of Buildings 190, 212 and 219 may have LBP that could be released to the soil. DTSC will have to determine whether, pursuant to CERCLA 120(h)(3); all actions have been taken at CO Areas 3 and 4 to remedy potential releases of lead to the environment from LBP. Based on this determination, DTSC will decide if CO Areas 3 and 4 are suitable for transfer. Thank you for providing DTSC with the opportunity to review this FOSL.

This FOSL updates and supercedes the interim FOSL for Parcels 1, 2, 18, 19, 20, 21, and 22 dated September 2000. The areas addressed in this FOSL and proposed for a Lease in Furtherance of Conveyance (LIFOC) at MCAS Tustin include Installation Restoration Program (IRP) sites, areas of concern (ADCs), and areas that are currently under evaluation or remediation of impacted soils and/or groundwater. Because of the nature of the ongoing environmental investigation and/or remediation, the property contained within these areas cannot be conveyed per the provisions of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Section 120(h)(3)(A)(ii) for the conveyance of federal property. Leased properties however, may be used in accordance with the terms of each lease with acceptable risk to human health and the environment. For the purposes of this FOSL, seven carve -out (CO) areas have been designated to encompass the areas of MCAS Tustin with ongoing environmental investigations and/or remediation. Each of the CO areas includes a buffer zone around the impacted area to protect human health and the environment during ongoing investigation and/or remediation. The purpose of designating CO areas is to: • Identify limited areas where restrictions are needed to prevent human exposure to potential contaminants while remedial action and ongoing investigations are being conducted, • Establish boundaries wherein restrictions will be imposed to control subsurface excavation of potentially contaminated soil and/or impacted shallow groundwater, • Prevent extraction and use of contaminated groundwater, • Prevent interference during investigation activities, • Allow access for monitoring and remedial activities, and • Prevent interference with the operation of any remediation system that may be installed on the properties in the future. The findings of suitability to lease supported by this document will be in effect for all properties included herein until the properties are found suitable for transfer by deed per the provisions of Section 120(h) of CERCLA. Specific terms of each lease will be FOSL 3, MCAS Tustin 1 April 2002 identified in the lease documents for each parcel or portion of a parcel. Ultimate parcel uses in the CO areas are designated as one of four categories: Educational/ Recreational, Commercial/ Business, Residential, or Circulation Facilities. These categories incorporate the specific parcel uses designated in the proposed reuse plan for WAS Tustin. This FOSL was prepared in accordance with United States Department of Defense (DoD) guidance documents, including the DoD Base Reuse Implementation Manual (DoD 1997) and the DoD Policy on the Environmental Review Process to Reach a Finding of Suitability to Lease (DoD 1996a). This FOSL is based on information contained in the final Basewide Environmental Baseline Survey (EBS) for MCAS Tustin Report (BNI 2001a) as well as information contained in the documents listed in Attachment 1 - References. . IRP site designations, building/ structure designations, and prior uses in this FOSL were derived from the final EBS Report. Proposed uses of the properties included in this FOSL are consistent with those presented in the MCAS Tustin Specific Plan/Reuse Plan Errata (Reuse Plan) (City of Tustin 1998). A Finding of Suitability to Transfer (FOST) was prepared concurrently with this FOSL to support conveyance of the portions of Parcels 1,16,17, 24, 27, 28, 40, and 41 that are not included herein as CO areas (DON 2002b). Several other parcels (23, 29, 34, 35, and 36) that do not include CO areas are also addressed in the FOST. The FOST, known as FOST 3 was finalized on 22 April 2002. Additional FOSTs will be prepared for properties included in this FOSL after they have been determined to be suitable for transfer pursuant to CERCLA Section 120(h). This FOSL is the third in a series of FOST and FOSL documents prepared for the transfer/ lease of parcels within MCAS Tustin. Figure 2 shows the boundaries of property included in this and the previous documents. The documents referenced herein are available from the information repository in the government document section of the main library at the University of California at Irvine and the administrative record file located at Southwest Naval Facilities Engineering Command. FOSL 3, WAS Tustin 2 April 2002 2.0 PROPERTY DESCRIPTION MCAS Tustin is located in southern California near the center of Orange County, approximately 40 miles south of downtown Los Angeles (Figure 1). The installation encompasses approximately 1,600 acres. The majority of MCAS Tustin is located within the city of Tustin, however approximately 95 acres in the southeast corner of the base fall within the city limits of Irvine. The base is bordered by the cities of Tustin, Irvine, and Santa Ana. MCAS Tustin was commissioned in 1942 as a DON lighter -than -air base. The installation was used to support observation blimps and personnel conducting antisubmarine patrols off the coast of southern California during World War II. In 1949, the base was officially decommissioned as an active facility because of the diminished need for blimp patrols. However, in 1951, the base was reactivated to support helicopter operations for the Korean War and was renamed the "Marine Corps Air Station (Helicopter) Santa Ana." In 1978, the installation name was changed to "MCAS (H) Tustin' to reflect its annexation by the city of Tustin. In 1986, the installation was renamed "MCAS Tustin." MCAS Tustin was operationally closed on 02 July 1999 in accordance with the Defense Base Closure and Realignment Act of 1990. Currently, the majority of the buildings are vacant, and the primary activities at the base are maintenance and environmental cleanup. The seven CO areas addressed in this FOSL together comprise approximately 315 acres located in.the northern, central, and eastern portions of MCAS Tustin (Figure 2). The seven CO areas and their associated parcels are described below and shown in Figure 2. • CO -5, approximately 235 acres, includes Parcels 2,18,19, 20, and 22, and portions of Parcels 1, 16,17, 24 and 40. • CO -6, approximately 32 acres, includes portions of Parcel 16. • CO -7, approximately 4 acres, includes portions of Parcels 16 and 40. • CO -8, approximately 21 acres, includes portions of Parcels 16, 27, and 40. • CO -9, approximately 2 acres, includes portions of Parcels 27 and 40. • CO -10, approximately 18 acres, includes portions of Parcels 28, 40 and 41. • CO -11, approximately 2.5 acres, includes portions of Parcel 1. Parcel designations shown in Figure 2 are consistent with those presented in the EBS Report and the final MCAS Tustin Specific Plan/ Reuse Plan Errata (Reuse Plan), except for Parcels 16, 27, and 40, which have been slightly modified (City of Tustin 1998). FOSL 3, MCAS Tustin 3 April 2002 Approximate CO area boundaries are shown in Figure 2. Features located within the CO areas include: • 117 buildings and 33 structures as shown on Figure 3; • 144 AOCs and Mooring Pads 4 and 5 as shown on Figure 4; • 73 former underground storage tanks (USTs) and 10 former aboveground storage tanks (ASTs) as shown on Figure 5; • 8 IRP sites, including IRP -1, IRP -3, IRP -5 (including IRP -5N and IRP-5S(a)), IRP -9 (including IRP -9A and IRP -9B), IRP -11, IRP -12, IRP -13 (including IRP -13E, IRP - 13S, and IRP -13W), and IRP -16 as shown on Figure 6; and • 92 monitoring wells, 5 surface water gauging locations, and 3 landfill gas monitoring probes as shown on Figure 7. Information concerning the former use of the buildings/ structures is provided in Table 1. Asbestos -containing material (ACM) and polychlorinated biphenyl (PCB) surveys have been conducted in many of the buildings/ structures. ACM and PCB survey results are summarized in Tables 2 and 3, respectively. Summary information for the AOCs is provided in Table 4. Summary information for the former USTs and ASTs is provided in Table 5. Groundwater monitoring wells, surface water gauging locations, and landfill gas monitoring probes located within the CO areas are listed in Table 6. FOSL 3, MCAS Tustin 4 April 2002 3.0 ENVIRONMENTAL CONDITION OF THE PROPERTY The environmental restoration, environmental planning, and compliance programs at MCAS Tustin have been derived from and are being implemented pursuant to the following regulatory mechanisms: • CERCLA, as amended by the Superfund Amendments and Reauthorization Act and the Community Environmental Response Facilitation Act • Resource Conservation and Recovery Act (RCRA) • National Environmental Policy Act (NEPA) • California Environmental Quality Act (CEQA) • Petroleum Corrective Action Program (PCAP) • California Health and Safety Code DON is the lead federal agency regarding environmental restoration at MCAS Tustin. The California Environmental Protection Agency (Cal EPA) Department of Toxic Substances Control (DTSC) is the lead regulatory agency providing oversight. MCAS Tustin is not listed on the National Priorities List. A Federal Facility Site Remediation Agreement (FFSRA) between DON -and DTSC for MCAS Tustin was signed on 1& August 1999. The FFSRA defines DON's corrective action and response obligations under RCRA and CERCLA. Since 1993, the Base Realignment and Closure (BRAC) Cleanup Team (BCT) has coordinated cleanup and closure activities at MCAS Tustin. The BCT consists of representatives from DON, the United States Environmental Protection Agency (U.S. EPA), the Cal EPA Santa Ana Regional Water Quality Control Board (RWQCB), and DTSC. These agencies reviewed and commented on the required documents included in Attachment 1- References. Potential environmental impacts pertaining to the disposal and reuse of MCAS Tustin were addressed in the final Environmental Impact Statement (EIS)/Environmental Impact Report (EIR) (DON 1999a) and were disclosed to agencies and the public for comment and review in compliance with the requirements of NEPA and CEQA. The EIS/EIR was prepared through the joint effort of DON (EIS) and the city of Tustin (EIR). DON prepared a NEPA Record of Decision (ROD) to document the selected proposed alternative for reuse at each of the parcels discussed in the EIS/ EIR. The NEPA ROD was executed on 02 March 2001 (DON 2001). FOSL 3, MCAS Tustin 5 April 2002 3.1 Area Types The BRAC Cleanup Plan Guidebook (DoD 1996b) provides the BCT with direction to classify base property into one of seven area types in order to facilitate and support reuse and transfer. Descriptions of the seven area types are provided in Table 7. The area types are ranked in order of their suitability for transfer. Area types 1 through 4 are considered suitable for transfer by deed. Area types 5 and 6 are considered unsuitable for transfer by deed until all remedial actions have been completed or after the remedy has been demonstrated to be operating properly and successfully. Areas classified as area type 7 either have not been evaluated or require further evaluation in order to classify them into one of the other area types. The boundaries of CO areas 5, 6, 7, 8, 9, 10, and 11 encompass properties designated as area types 5 and 6, although some area type 1-4 properties are also present within the CO areas. The designated area types associated with environmental concerns (AOCs, UST/ ASTs, or IRPs) are listed on Tables 4 and 5 and shown on Figures 4 and 5. All AOCs and UST/ AST sites in the CO areas have been designated as Area Types 1 through 6 (Tables 4 and 5, respectively). One area currently under evaluation, Mooring Pads 4 and 5, is designated area type 7. Where AOCs, USTs, or ASTs (classified as Area Types 1 through 4) lie within the boundaries of an IRP site that has been classified as an area type 5 or 6, the area -type designation shown on Tables 4 and 5 depicts the environmental conditions associated with the AOC, UST, or AST rather than that of the IRP site. The CO areas contain seven active IRP sites (IRP -1, IRP -3, IRP -5 [including IRP -5N and IRP-5S(a)], IRP -11, IRP -12, IRP -13 [including IRP -13S and IRP -13W], and IRP -16) and two IRP sites that have received regulatory concurrence for no further action (NFA) (IRP -9 [including IRP -9A and IRP -9B] and IRP -13E). The IRP sites are being addressed in different Operable Units (OUs) that have been designated for further evaluation and/or remediation. All IRP sites are shown on Figure 6. • OU -1A includes one area type 6 IRP site (IRP -13S) and two area type 6 AOCs (MWA-18 and ST -72B). OU -1A was created to address groundwater contaminated with chlorinated volatile organic compounds (VOCs) with concentrations exceeding drinking water maximum contaminant levels (MCLS). OU -1A activities are being coordinated with the PCAP for an adjacent methyl tertiary -butyl ether (MTBE) plume. A time -critical removal action is currently underway, and a Feasibility Study (FS) is currently being prepared for OU -1A. • OU -1B includes two area type 6 IRP sites (IRP -3 and IRP -12) and two area type 6 AOCs (TOW -X3 and TOW -X4). OU -1B was created to address contaminated groundwater plumes consisting primarily of dissolved trichloroethylene (TCE) with minor amounts of other chlorinated VOCs at concentrations that exceed FOSL 3, WAS Tustin 6 April 2002 MCLs. The FS was completed in January 2002, and a Proposed Plan is being prepared for OU -1B. • OU -2 includes three area type 4 IRP sites, (IRP -2, IRP -9 [including IRP -9A and IRP -9B], and IRP -13E). IRP -2 and portions of IRP -9B are included in the accompanying FOST. IRP -9A, IRP -13E, and portions of IRP -9B are included in .the CO areas. Final closure for these three IRP sites was received with the signing of the OU -2 NFA ROD/ Remedial Action Plan in September 2000 (Attachment 2). • OU -3 includes one area type 5 IRP (IRP -1), formerly consisting of unlined shallow landfill trenches and pits constructed to burn flammable liquids for firefighter training exercises. These activities resulted in VOC and polynuclear aromatic hydrocarbon (PAH) contamination of soil and groundwater. A ROD was issued in December 2001 and an Operations and Maintenance Plan is currently being prepared. • OU -4 includes four area type 6 IRP sites, (IRP -5 [including IRP -5N, IRP-5S(a),and IRP-5S(b)], IRP -6, IRP -8, and IRP -11), two area type 5 IRP sites (IRP -13W, and IRP -16), and thirteen area types 4-6 AOCs (DSD -1, DSS -1, DSS -2, MAE-4, MDA - 02, MMS -4, MMS -5, ST -14 (A -C), ST -15, ST -16A, ST -16B, ST -67, and TOW -X7). IRP-5S(b), IRP -6, and IRP -8 are included in a previous FOSL and the remaining IRP sites and AOCs are included in the CO areas. These OU -4 sites, with the exception of ST -16A and B, all contain areas of VOC groundwater contamination above MCLs. ST -16A and ST -16B contain areas of PAH contamination in soil. A focused FS report for OU -4 is currently being prepared. One hundred and forty-four identified AOCs are present within the CO areas (Figure 4). The majority of these AOCs (125) have received regulatory concurrence for NFA. Regulatory NFA concurrence signature pages for these AOCs are included in Attachment 2. The current status of AST/ UST sites within the CO areas that have not received NFA concurrence is provided below: • Two AOCs, MMS -7 and DSD -07 (in CO -5), are under further investigation, and will be evaluated under the RCRA program. • The remaining seventeen AOCs are associated with one of the four OUs and are present in CO -5, CO -6, and CO -7. These AOCs require further evaluation and are being addressed in the IRP for MCAS Tustin. The current status of the AOCs is provided in Table 4 and AOC locations are shown on Figure 4. CO -8 contains an additional area under evaluation known as Mooring Pads 4 and 5 These pads were formerly used to support activity for thermal desorption units, however they have not been formally designated as AOCs. FOSL 3, MCAS Tustin April 2002 Seventy-three USTs and ten ASTs were formerly located within the CO areas (Figure 5). All ASTs and USTs have been removed and fifty-eight have received regulatory concurrence for NFA. The current status of AST/ UST sites within the CO areas which have not received NFA concurrence is provided below: • Six UST sites are awaiting concurrence for NFA (UST -105A, B, C, D, E, and F). • The remaining nineteen UST/ AST sites (UST -1, UST -16, UST -18A and B, UST - 27A and B, UST -29A, UST -90, UST -135, UST -222A, B, C, D, G, H, and I, UST -268, and AST -194A and B) require further action and have ongoing investigations or are conducting remediation. Extraction and treatment of MTBE contaminated groundwater associated with UST -222 is currently underway under the PCAP. The current status of these UST/ AST sites is provided in Table 5. The former UST and AST locations are shown on Figure 5. 3.2 Environmental Concerns within CO Areas Environmental conditions are described below for each of the CO areas. 3.2.1 CO -5 The approximate acreage of CO -5 is 235. acres. This CO area includes four IRP sites (IRP -11, IRP -12, IRP -13 [including IRP -13S and IRP -13W], and IRP -16), and various UST/ AST sites and AOCs. The environmental concerns related to these sites are discussed below. Figure 8 is a detailed map of CO -5 that indicates areas of known contamination and buildings within the CO area. 3.2.1.1 IRP Sites in CO -5 CO -5 contains several areas where VOC concentrations in the underlying groundwater exceed MCLs. The estimated location and extent of the VOC groundwater plumes are based on currently available data from documents included in Attachment 1 - References. Descriptions of these IRP sites are provided below. IRP -11 IRP -11 is part of the study area designated as OU -4. IRP -11, known as Drum Storage Area number (No.)1, was used for drum storage from 1975 to 1984 and is located in Parcels 18 and 40 (Figure 6). Materials stored at the site included hydraulic fluids, crankcase oils, solvents, and aviation parts. TCE was detected in groundwater during an Expanded Site Inspection (BNI 1996a). IRP -11 is currently under evaluation as part of the ongoing FS for OU -4. FOSL 3, MCAS Tustin $ April 2002 IRP -12 IRP -12 is part of the study area designated as OU -1B. IRP -12, also known as Drum Storage Area No. 2, operated from the mid-1960s until 1975 and is located in Parcels 16, 17,18 and 40 (Figure 6). The site contains three subareas where various solvents, crankcase oil, and hydraulic fluids leaked from storage drums and containers. Two VOC plumes have been identified in the first water -bearing zone, and two smaller VOC plumes have been identified in the second water -bearing zone. The plumes consist primarily of dissolved TCE with minor amounts of other chlorinated VOCs (BNI 2001a). Fate and transport modeling and a baseline risk assessment were conducted (BNI 1997) to address risks associated with shallow VOC groundwater contamination as part of the Remedial Investigation (RI) for OU -1B. The FS for OU -1B evaluated the possible volatilization of VOCs from contaminated soils and groundwater associated with the VOC plume. The FS determined that the inhalation exposure pathway for human receptors did not present a significant risk (BNI 2002a). The concentration of TCE in soils was also determined not to present significant risk. The FS for OU -1B includes an evaluation of seven alternatives for the remediation of VOCs in groundwater beneath IRP -12. TRP -1 .;S IRP -13S is part of the study area designated as OU -1A. IRP -13S is part of the area known as Drum Storage Area No. 3, and is located on portions of Parcels 1, 2,16,18,19, 22, 24, and 40 (Figure 6). This IRP site includes two AOCs (MWA-18 and ST -72B), an inactive wash area formerly used for cleaning small generators, and an inactive vehicle maintenance facility that formerly consisted of a garage and a lubrication facility. During the RI, TCE and 1,2,3-trichloropropane (TCP) were found in both soil and groundwater at IRP -13S. The likely sources were identified as past disposal or spills onto the ground. The VOC groundwater plume has overlapped with an adjacent MTBE plume, most likely originating from UST Site 222 (BNI 2001a). A time -critical removal action was initiated in late 2001 to extract and treat contaminated groundwater within the IRP -13S plume. An FS is currently being prepared to identify remedial alternatives for IRP -13S. TR P-1 _1W IRP -13W (Figure 6) is part of the area known as Drum Storage Area No. 3. IRP -13W consists of two past disposal areas located in the northwest portion of Parcel 24 and contains portions of Parcel 40. IRP -13W is being evaluated under OU -4. Hydraulic fluid, diesel fuel, leaded gasoline, oil, paint strippers, battery acids, solvents and solvent -contaminated washwater were disposed onto IRP -13W soils. Petroleum hydrocarbons, elevated concentrations of metals, and PAHs were found in soil and groundwater. The risk posed by chemicals in the soil was estimated to be above the FOSL 3, MCAS Tustin 9 April 2002 generally allowable risk range. Approximately 3,700 tons of soil were removed in November 1997 (BNI 2001a). Groundwater contamination at the site is currently under evaluation as part of the ongoing FS for OU -4. IRP -16 IRP -16, located on Parcel 24, was a former fuel tank farm (Figure 6) and is being evaluated as part of OU -4. The site was the subject of a confirmation study in 1987 and 1988 and a fuel tank farm site assessment in 1993. Based on the presence of benzene, toluene, ethylbenzene, xylenes, and total petroleum hydrocarbons in soil and groundwater, excavation and restoration activities were conducted in 1995 and 1996. Approximately 85,000 tons of contaminated soil were excavated and treated, and 5 million gallons of groundwater were recovered and treated. The site is currently under evaluation as part of the ongoing FS for OU -4.. 3.2.1.2 AOCs in CO -5 Further action at two ADCs (MWA-18 and ST -72B) is being addressed as part of OU -1A for MCAS Tustin. MWA-18 and ST -72B are located in CO -5 on the northwest edge of Parcel 24 (Figure 4). During the RI, TCE and 1,2,3 -TCP were found in both soil and groundwater at IRP -13S, and the likely sources were identified as past disposal or spills onto the ground. Specifically, the final RI report identified AOC ST -72B as the probable source of 1,2,3 - TCP groundwater contamination. Closure activities for this AOC included the performance of a time critical removal action to excavate petroleum -hydrocarbon - contaminated soils. Post excavation confirmation samples reported no 1,2,3 -TCP concentrations (BNI 1997). These sample results and further RI findings suggest that residual 1,2,3 -TCP in soil is essentially immobile, indicating that ST -72B is no longer considered a source of significant groundwater contamination, although it may have been a source of the 1,2,3 -TCP at one time (BNI 2001a). The final RI report concluded that MWA-18 is a probable TCE source area for IRP -13S, as it is within the footprint of TCE groundwater and soil contamination (BNI 1997). Closure activities under CERCLA are continuing for ST -72B and MWA-18 as part of OU -1A. Further evaluations are required at the Mingled Plume AOCs (DSS -1, DSS -2, MDA -02, MMS -5, and ST -67) and the Auto Hobby Shop AOC (MMS -4). Soils at the Mingled Plume AOCs and MMS -4 have been recommended for NFA, and the VOC- contaminated groundwater in the Mingled Plume and MMS -4 is being addressed as part of OU -4. AOC sites MAE-4, ST -14 (A -C), ST -15, and TOW -X7 were assessed as part of IRP -13W. MAE-4 and ST -15 were demolished as part of the removal action for IRP -13W. Closure FOR 3, WAS Tustin 10 April 2002 activities for ST -14 (A -C) were conducted as part of the removal action for IRP -13W, and TOW -X7 was removed as part of the IRP -13W removal action (Table 4). Two AOCs, MMS -7 and DSD -07 (in CO -5), are under further investigation, and will be evaluated under the RCRA program. 3.2.1.3 UST Sites in CO -5 UST Site 1 UST -1, located in Parcel 20, was removed in 1993. Site soils with total petroleum hydrocarbon (TPH) and benzene contamination were excavated during the removal, and the site was backfilled and restored. A site investigation took place in December 1995 and the resulting 1997 Site Assessment/ Closure Report recommended NFA for the site (BNI 2001a). The RWQCB issued an NFA concurrence letter on January 8,1998. However, subsequent groundwater monitoring at the site showed high detections of TPH. DON conducted further subsurface investigations and modeling at the site and presented the results in a November 2001 Technical Memorandum (IT 2001b). This study found that the remaining contamination is not migrating downward and that TPH and benzene concentrations at the site are reducing due to naturally occurring biological degradation. The Technical Memorandum concluded that the remaining contamination poses no significant threat to groundwater at the site and may be left in place (IT 2001b). In a January 7, 2002 letter, the RWQCB stated that it did not concur with DON's Technical Memorandum conclusions for UST -1. RWQCB stated that the remaining TPH concentrations in soil and groundwater indicate that free product (liquid phase fuel) could potentially be present on the groundwater surface. DON is currently conducting further investigation of groundwater at the UST -1 site. UST Site 222 Petroleum hydrocarbon and MTBE soil and groundwater contamination was encountered at UST Site 222 (including former USTs 222A, B, C, D, G, H, and I). Under the PCAP all of the USTs at the site were removed, and Building 222, a former gasoline station, was demolished in June 1999. Field activities took place from March 1998 to November 1999. The site was excavated, backfilled, and restored. Approximately 37,000 tons of contaminated soil was excavated and treated, and approximately 2 million gallons of contaminated groundwater within the excavated area were removed and transported offsite for treatment. MTBE concentrations in the excavation groundwater ranged from 6 to 600 milligrams per liter (mg/L). Investigation of groundwater at UST Site 222 continued through 2001. MTBE was detected in shallow groundwater in the vicinity of UST 222. The available data suggests FOSL 3, MCAS Tustin 11 April 2002 mixing between the MTBE groundwater plume and the 1,2,3 -TCP groundwater plume in the first water -bearing zone, and additional mixing in the second water -bearing zone downgradient from the source area. The highest reported concentrations of MTBE in groundwater samples were greater than 70 mg/L from the first water -bearing zone and greater than 24 mg/L from the second water -bearing zone (during the August 2000 monitoring event). Further results from groundwater investigation suggest that the MTBE and 1,2,3 -TCP plumes may be mixed in the third water -bearing zone (BNI 2001a). An MTBE groundwater extraction/ treatment system has been designed and installed under the PCAP. The interim corrective action will focus on extracting and treating MTBE hot spots in groundwater. Pumping began at the site in August 2001 within the source area and downgradient wells were brought online in December 2001. Potential long-term corrective actions for the MTBE plume will be developed and evaluated. UST Sites 105A, B, C, D, E, and F UST Site 105 (including USTs 105A, B, C, D, E, and F) (Figure 5), is the location of a former gasoline station. This site exhibited elevated levels of benzene, toluene, ethylbenzene, and xylenes in groundwater. Operation of an in situ soil vapor extraction/ air sparging remediation system began in May 1999 and continued through July 1999. Monthly groundwater samples were collected from May 1999 through 15 September 1999, and results indicated that there was no rebound increase in concentrations after the system was turned off. Quarterly monitoring continued through June 2000 and contaminant concentrations continued to decrease. Closure activities have been completed at the site, and a draft Closure Report was submitted to RWQCB on February 19, 2001 (OHM 2001a). NFA concurrence is pending. UST Sites 18A and 18B UST Sites 18A and 18B are former 1,000 -gallon, steel, gasoline USTs that were removed prior to 1991. Assessment and remediation of these sites is ongoing. Additional UST sites UST Sites 16, 27A, 27B, 90,135, and 268 require further action and have ongoing investigations or are conducting remediation. 3.2.2 CO -6 The approximate acreage of CO -6 is 32 acres. This CO area includes IRP -3, UST -29A, and AOC sites TOW -X3 and TOW -X4. The environmental concerns related to these sites are discussed below. Figure 9 is a detailed map of CO -6 that indicates areas of known contamination and buildings within the CO area. FOSL 3, WAS Tustin 12 April 2002 3.2.2.1 IRP Sites in CO -6 IRP -3 is part of the study area designated as OU -1B. IRP -3, the Paint Stripper Disposal Area, is located in the southern portion of Parcel 16 (Figure 6) and includes two AOCs (TOW -X3 and TOW -X4). IRP -3 contains several buildings that have been used for chemical storage, painting, paint -stripping operations. Solvents, paint stripper, and battery acids were reported to have been poured directly onto the ground outside the painting and storage buildings (BNI 1997). TCE was found in both soil and groundwater at IRP -3. Sources of TCE may have been inactive oil/water separators (TOW -X3 and TOW -X4) and past disposal or spills onto the ground. A groundwater VOC plume has been identified in the first water -bearing zone beneath IRP -3, and a smaller groundwater VOC plume has been identified in the second water -bearing zone. The plumes contain dissolved TCE with minor amounts of other chlorinated VOCs at concentrations that exceed MCLs. The FS for OU -1B was finalized in January 2002 and includes an evaluation of nine alternatives for the remediation of TCE in groundwater beneath IRP -3. The Proposed Plan is currently being prepared. 3.2.2.2 AOCs in CO -6 Further action at two AOCs (TOW -X3 and TOW -X4) is being addressed as part of OU_ 1B for MCAS Tustin. TOW -X3 and TOW -X4 are located in CO -6 in Parcel 16 (Figure 4). Two oil/water separators AOCs (TOW -X3 and TOW -X4) were evaluated in conjunction with IRP -3. These inactive oil/ water separators may have been sources of TCE at IRP -3. The oil/water separators and associated contaminated soils were removed in 1999, but residual TCE contamination in soil and groundwater remains at the sites. The TCE in soils was determined not to present significant risk at the site. The two AOC sites will undergo CERCLA closure in association with IRP -3 as part of OU -1B (BNI 2000). 3.2.2.3 UST Sites in CO -6 UST Site 29A requires further action and is under investigation. 3.2.3 CO -7 The approximate acreage of CO -7 is 4 acres. This CO area includes IRP -5N and AOCs ST -16A, ST -16B, and DSD -1. The environmental concerns related to these sites are discussed below. Figure 9 is a detailed map of CO -7 that indicates areas of known contamination and buildings within the CO area. FOSL 3, MCAS Tustin 13 April 2002 3.2.3.1 IRP Sites in CO -7 IRP -5N is a part of the study area designated as OU -4. IRP -5N consists of an unlined drainage ditch in the area known as Drainage Area No. 1, located in the eastern portion of Parcel 16 (Figure 6). From 1956 to 1983, the ditch may have received a variety of wastes disposed in floor drains from Buildings 28 and 29 as well as runoff from other potential contaminant source areas. Analytical results from sediment, soil, and surface water sampling indicated the presence of petroleum hydrocarbons, semivolatile organic compounds, and metals at levels above background in some of the sediment samples. The risks posed by these chemicals were estimated to be within the generally allowable risk range. IRP -5N is currently under evaluation as part of the ongoing FS for OU -4 along with IRP-5S(b). 3.2.3.2 AOCs in CO -7 AOCs ST -16A and ST -16B were former hazardous waste storage areas that stored wastes including paints, used fuel, filters, and rags. During the initial investigation of these AOCs, PAH contamination was found in the soils. These ADCs will,.be evaluated as part of OU -4 under the CERCLA program. DSD -1 is being assessed as part of IRP -5N (OU -4) and is currently under investigation. 3.2.4 CO -8 The approximate acreage of CO -8 is 21 acres. Figure 9 is a detailed map of CO -8 that indicates areas of known contamination and buildings within the CO area. Mooring Pad 4 and a portion of Mooring Pad 5 are included within CO -8 and were previously used to land and lance lighter -than -air blimps. In 1995, a thermal desorption unit was installed on Pad 4 for treatment of TPH contaminated soil brought in from other areas of MCAS Tustin. The soil was stored on a layer of visqueen (plastic) and roadbase material placed on top of the existing asphalt. Stockpiles of soil on the pad were covered with visqueen. In 1997, Pad 5 was utilized for an equipment storage area, storage and rehydration of treated soil, and temporary storage of TPH-contaminated soil. The mooring pads are being evaluated to address whether thermal desorption unit activities have resulted in soil or groundwater contamination beneath the pads. 3.2.5 CO -9 The approximate acreage of CO -9 is 2 acres. This CO area includes IRP-5S(a). The environmental concerns related to this site are discussed below. Figure 9 is a detailed map of CO -9 that indicates areas of known contamination and buildings within the CO area. FOSL 3, MCAS Tustin 14 April 2002 3.2.5.1 IRP Sites in CO -9 IRP-5S(a) is part of the study area designated as OU -4. It is an unlined drainage ditch in the area known as Drainage Area No. 1, located in the southern portion of Parcel 27 and portions of Parcel 40 (Figure 6). From 1956 to 1983, the ditch may have received a variety of wastes disposed in floor drains from Buildings 28 and 29 as well as runoff from other potential contaminant source areas. Analytical results from sediment, soil, and surface water sampling indicated the presence of petroleum hydrocarbons, semivolatile organic compounds, and metals at levels above background in some of the sediment samples. One VOC above the MCL was reported in one of nine collected. groundwater samples. In a risk assessment performed as part of the RI for OU -4, the risks posed by these chemicals were estimated to be within the generally allowable risk range (BNI 2001a). IRP-5S(a) is currently under evaluation as part of the ongoing FS for OU -4 along with IRP -5N. 3.2.6 CO -10 The approximate acreage of CO -10 is 18 acres. This CO area includes IRP -1. The environmental concerns related to this site are discussed below. Figure 10 is a detailed map of CO -6 that indicates areas of known contamination and buildings within the CO area. 3.2.6.1 IRP Sites in CO -10 IRP -1 is part of the study area designated as OU -3, and is located on Parcels 28, 40 and 41. IRP -1 includes the Moffett Trenches and Crash Crew Burn Pits (Figure 6), which were shallow landfill trenches and pits constructed to burn flammable liquids for fire- fighter training exercises. A mixture of municipal solid and industrial wastes were disposed in the landfill trenches. Flammable liquids burned in the Crash Crew Burn Pits consisted primarily of jet propellant grade 5 (JP -5) but also reportedly included oils, fuels, solvents, lacquers, primers, and various chemicals (BNI 2001a). The principal contaminants at the site are petroleum hydrocarbons (JP -5), VOCs, semivolatile organic compounds, and, to a lesser extent, metals. Most of the site -related contamination is present in the groundwater of the first water -bearing zone. Based on a risk assessment, estimated human -health risks associated with residential use of groundwater from the first water -bearing zone exceed the U.S. EPA's generally acceptable range (BNI 1996a). Maintenance of a containment wall, institutional controls, and long-term groundwater and landfill gas monitoring were identified as the preferred remedial alternatives for IRP -1 in the Final ROD for OU -3 issued in December 2001. An Operations and Maintenance Plan and a Land Use Control and Implementation Certification Plan are currently being prepared to support implementation of the final remedy. FOSL 3, MCAS Tustin 15 April 2002 3.2.7 CO -11 The approximate acreage of CO -11 is 2.5 acres. This CO area includes the area affected by AST -194A and AST -194B. The environmental concerns related to these sites are discussed below. Figure 8 is a detailed map of CO -11 that indicates areas of known contamination and buildings within the CO area. 3.2.7.1 AST Sites in CO -11 AST -194A and AST -194B were formerly situated adjacent to a concrete helicopter parking apron. The ASTs supplied fuel to the apron for rapid refueling activities, and spill runoff would flow to the edge of the concrete apron. AST -194A and AST -194B were removed and the immediate vicinity was excavated and cleaned in 1999. However, further investigation indicated that soils at the edge of the apron may have been impacted from past refueling activities. This area is currently under investigation. FOSL 3, MCAS Tustin 16 April 2002 4.0 NOTIFICATIONS AND RESTRICTIONS The environmental documents listed in Attachment 1 (References) were evaluated to identify environmental factors that may have impacted property within the CO areas. Section 3.0 describes the environmental concerns associated with each of the CO areas. The evaluation identified existing environmental conditions that warrant constraints on certain activities to assure that the intended use of the FOSL parcels during the leases is consistent with protection of human health and the environment. Environmental factors that require notification(s) and/or restriction(s) are presented in this section. Table 8 provides a list of environmental factors considered for this FOSL. Table 9 provides a cross reference to the section in this document where the notifications and restrictions applicable to each CO area, parcel, and building/ structure included in this FOSL can be found. Restrictions in this FOSL will be incorporated into leases of affected properties within the CO areas. Notification will be provided to the lessee by attaching a copy of this FOSL to each lease. The prospective lessee(s) will be required to comply with the restrictions specific to their property and additional model environmental lease provisions substantially similar to those provided in Attachment 3. If a building, structure, or a portion of a CO area is released from a restriction, a Lease Restriction Revision Form (Attachment 4) will be required to allow access to and/or transfer of the area under the lease. For the purposes of this FOSL, "Structures" not designated for human occupancy include non -enclosed facilities, such as, sports fields, picnic shelters, pump stations, etc. 4.1 Hazardous Substances and Petroleum Products Notifications Past activities within all of the CO areas included the use and storage of hazardous substances and petroleum products. Releases of hazardous substances have occurred during these activities. A notice of hazardous substances stored, released, or disposed at specific AOC and UST/ AST sites within the CO areas is provided in Attachment 5 - Hazardous Substances Notification Table and Petroleum Products Notification Table. IRP -13S (OU -1A), IRP -3 and IRP -12 (OU -1B), IRP -1 (OU -3), and IRP -5N, IRP-5S(a), IRP- 11, IRP -13W, and IRP -16 (OU -4) have not received regulatory closure and are currently being evaluated. IRMA, IRP -9B, and IRP -13E (OU -2) have received NFA concurrence. Information concerning contaminants associated with the active IRP sites in the CO areas is provided in Section 3.2 of this FOSL. FOSL 3, MCAS Tustin 17 April 2002 Restrictions • The lessee shall not conduct or permit its sublessees to conduct any subsurface excavation, digging, drilling or other disturbance of the surface within the entire CO area without the prior approval of DON and the BCT. Attachment 3, Section 13.11 contains an example model lease provision. This restriction is applicable to all CO areas. 4.2 Areas of Concern and Areas Under Evaluation The following discussion provides notifications and restrictions required due to AOCs or areas under evaluation within the CO areas. Notifications Summary information for the 144 AOCs and Mooring Pads 4 and 5 that are located within CO areas 5, 6, 7, 8, 10, and 11 is presented in Table 4. CO -9 does not contain any AOCs or areas under evaluation. The AOC locations are shown on Figure 4. The majority of these ADCs (125) have received regulatory concurrence for NFA. Two AOCs, ST -16A and B (in CO -7), are under further investigation, and will be evaluated under CERCLA. The remaining seventeen ADCs require further evaluation and are being addressed in the IRP for MCAS Tustin. Soil and groundwater beneath Mooring Pads 4 and 5 are currently under evaluation by DON. Restrictions The lessee shall not conduct or permit its sublessees to conduct any subsurface excavation, digging, drilling or other disturbance of the surface within the entire CO area without the prior approval of DON and the BCT. Attachment 3, Section 13.11 contains an example model lease provision. This restriction is applicable to CO areas 5, 6, 7,8, 10, and 11. 4.3 Unexploded Ordnance Notifications CO -5 includes portions of a former skeet range in Parcel 24 and CO -10 includes portions of the safety arc for a former pistol/ rifle range in Parcels 28, 40, and 41. Based on the historical uses of the ranges, potential ordnance or explosive hazards were limited to small caliber debris. In 1979 the pistol/ rifle range was deactivated and disposed of by demolition. The area was cleared and grubbed during base housing construction in 1979 and 1982; approximately 2-3 feet of native topsoil was removed and replaced with clean fill material. The former pistol/ rifle range was investigated as part of IRP -2 and FOSL 3, MCAS Tustin 18 April 2002 the RI recommended NFA for the site. All environmental investigations conducted at MCAS Tustin have suggested that ordnance and/or explosive hazards do not remain on the property (BNI 2001a). Restrictions There are no restrictions due to unexploded ordnance. 4.4 Radiological Materials Notifications A historical radiological assessment (Roy F. Weston 2000) was conducted at MCAS Tustin. The purpose of the assessment was to identify buildings where potential past or present use of radiological materials may have occurred and recommend those buildings for a radiological survey. On the basis of the assessment, the Nuclear Biological and Chemical (NBC) unit of Building 29 (CO -5, Parcel 16) will be investigated further in a radiological survey. Building 29 was an airship hangar where operating aircraft that used radioactive equipment were housed during maintenance activities. DON will perform a radiological survey to determine whether the NBC unit of Building 29 can be released for unrestricted use or whether institutional controls are necessary (Roy F. Weston 2001). Restrictions • The NBC unit of Building 29 will be prohibited from access pending the results of the radiological survey. Based on the survey results, DON will evaluate whether to release the building from this restriction. The survey results must also be approved by the regulatory agencies before the building is released for access under the lease. 4.5 Storage Tanks (USTs/ASTs) Notifications Past activities within the CO areas included the use of petroleum products. Summary information for the 83 UST/ AST sites that are located within CO areas 5, 6, and 11 is presented in Table 5. The UST/ AST site locations are shown on Figure 5. Seventy-three USTs and ten ASTs were formerly present within the CO areas. All USTs and ASTs have been removed and fifty-eight have received regulatory concurrence for NFA. Six are awaiting NFA approval (UST -105A, B, C, D, E, and F). The remaining nineteen (UST -1, UST -16, UST -18A and B, UST -27A and B, UST -29A, UST -90, UST -135, UST- FOSL 3, MCAS Tustin 19 April 2002 222A, B, C, D, G, H, and I, UST -268, and AST -194A and B) have ongoing investigations or are conducting remedial activities (Table 5). Restrictions • The lessee shall not conduct or permit its sublessees to conduct any subsurface excavation, digging, drilling or other disturbance of the surface within the entire CO area without the prior approval of DON and the BCT. Attachment 3, Section 13.11 contains an example model lease provision. This restriction is applicable to CO areas 5, 6, and 11. 4.6 Pesticides Notifications Agricultural areas are present on Parcels 17, 24, and 27. Portions of these parcels are contained in CO -5 and CO -8. The following discussion provides notifications that. are required based on previous use of pesticides and herbicides at these parcels. Approximately 674 acres of MCAS Tustin were previously designated for agricultural land or were maintained for weed control, of which about 392 acres were farmed ($NI 2001a). Farming was conducted within the base boundary prior to commissioning -of the base in 1942 and continued through December 2000. The primary agricultural areas are located in the southwestern and northeastern portions of the base. The former lessee, Osumi Farms, submitted monthly pesticide use reports to Cal -EPA, Department of Pesticide Regulation, regarding pesticide use on parcels under cultivation. Information concerning commercial pesticides and insecticides used at MCAS Tustin and chemicals injected into irrigation water is provided in the final EBS Report (BNI 2001a). In 1991 and 1992, a preliminary endangerment assessment (PEA) was conducted for Parcel 24 (PEA Parcel A), Parcels 38 and 39 (PEA Parcel C), and Parcel 33 (PEA Parcel D). These parcels were farmed before 1942 and were used for a combination of military and agricultural purposes after being acquired by DON in 1942. The PEA included soil and groundwater sampling and a health risk assessment for soil contaminant concentrations exceeding screening values. These contaminants included the pesticides dichlorodiphenyltrichloroethane (DDT), dichlorodiphenyldichloroethene (DDE), and dichlorodiphenyldichloroethane (DDD). The risk assessment assumed residential land use and exposure to adults and children by soil ingestion, soil contact, and inhalation of soil particles. Although soil contaminant levels exceeded some screening values, the risk assessment results indicated, on the basis of a residential -use scenario, that there was no significant environmental or human -health threat from the pesticides (GeoRemediation 1992). DTSC provided NFA concurrence on the findings in the PEA FOSL 3, MCAS Tustin 20 April 2002 for the areas containing Parcels 24, 33, 38, and 39. DTSC's 26 May 1992 NFA concurrence letter for Parcel A and 27 May 1992 NFA concurrence letters for Parcels C and D are provided in Attachment 2. Additionally, groundwater sample results presented in the draft final RI Report for OU - 1 and OU -2 (BNI 1997) did not indicate the presence of pesticides in groundwater beneath Parcel 24. While selenium was detected in groundwater during the RI at concentrations exceeding the PEA screening levels, an analysis of background metals in groundwater performed during the RI indicated that detected concentrations of selenium in groundwater were not the result of base operations, but were consistent with naturally occurring background concentrations. Further investigation in 1996 supported the PEA findings. Soil samples were collected from the southwest corner (Parcel 6) and the northeast quadrant (Parcels 17, 25, 26, 27, 28, 29, 30, 31, 32, and 40) of MCAS Tustin to evaluate whether residual pesticides and metals were present in soil as a result of past agricultural activities (BNI 1996b). This study included some or all of Parcels 17 and 27. The pesticides DDD, DDE, DDT, alpha - chlordane, dieldrin, endosulfan II, gamma -chlordane, and methoxychlor were detected in soil samples. Pesticide concentrations were compared with those reported in soil collected from Parcels 38 and 39 (PEA Parcel C) (considered to be representative worst- case scenarios). The results of the comparison indicated that pesticide concentrations in Parcels 17 and 27 were at levels below or within the statistical range calculated for Parcels 38 and 39. Therefore, it was concluded that residual levels of pesticides in soil in Parcels 17 and 27 do not constitute a threat to human health or the environment. Additionally, 11 metals were detected at concentrations above background values and some pesticides (DDD, DDE, and DDT) were detected that were not found during the Parcels 38 and 39 investigation. Therefore, a screening risk assessment using the highest measured concentrations and U.S. EPA residential soil preliminary remediation goals was conducted. The risk assessment used the conservative approximation that people would be present on the land 24 hours a day for 30 years. The screening risk assessment results for metals and pesticides indicated no significant risk to human health or the environment (BNI 1996b). The 1996 Pesticides Investigation Report was reviewed by the BCT whose comments were incorporated (see 15 July 1996 letter in Attachment 2). At the time of transfer, DON will provide the transferee with documentation regarding past pesticide use on the property as well as a copy of the PEA Report and the Pesticide Investigation Report. Although pesticides were reportedly applied to some or all of Parcels 17, 24, and 27, the PEA sampling and risk assessment and the pesticide investigation conducted in 1996 indicated that the property was suitable for unrestricted, residential use. FOSL 3, MCAS Tustin 21 April 2002 Restrictions • There are no restrictions due to prior pesticide usage. 4.7 Asbestos -Containing Material ACM is considered to be a threat to human health if it is located within the interior of a building/ structure, and it is friable, accessible and damaged (FAD). DoD policy with respect to ACM is contained in Attachment 6 and a graphic representation of this policy and the decision-making process is presented as Figure 11. The following sections summarize specific notifications and restrictions regarding the presence of ACM in some of the buildings/ structures located within the CO areas. Notifications Available information on the existence, extent, and condition of ACM at buildings/ structures within the CO areas is provided in Table 2. This information was collected from four ACM surveys conducted at MCAS Tustin. The survey results were presented in reports dated December 1988, November 1990, December 1991, and January 2001 (IT Corporation 1988; Ecology and Environment, Inc. 1991; URS 2001; respectively). The January 2001 surveys were limited to FAD ACM. Copies of the ACM survey reports will be included in the lease documentation. Restrictions The prospective lessee(s) will be required to comply with the specific restrictions listed below and additional environmental lease provisions substantially similar to those provided in Attachment 3, Section 13.12. The buildings and structures within the CO areas have been separated into the following four categories based on the survey findings to assist in determining the restrictions associated with asbestos: a) Buildings containing FAD ACM, b) Buildings/ Structures requiring an ACM survey, c) Buildings/ Structures with non -FAD ACM, d) Buildings/ Structures with no ACM, and e) Structures with no ACM surveys conducted. Within each category, the restrictions are further differentiated based on the proposed reuse of each building/ structure. FOSL 3, MCAS Tustin 22 April 2002 (a) Buildings Containing FAD ACM • Access or occupancy shall be prohibited except for short-term tours and emergency maintenance conducted with prior DON notification and approval. • Buildings may be occupied only after necessary surveys and abatement are conducted according to all local, state, and federal requirements. Occupancy restrictions may not be removed from these buildings without prior approval of DON and the BCT. The lessee shall be responsible for the management of ACM, including surveys, removal and/or management of ACM prior to or during renovation or demolition in accordance with applicable regulatory requirements.

(e) Structures With No ACM Surveys Conducted • The lessee shall be responsible for the management of ACM, including surveys, removal and/or management of ACM prior to or during renovation in accordance with applicable regulatory requirements. FOSL 3, MCAS Tustin 24 APS 2002 This restriction applies to the following structures planned for demolition, TBD, or unknown (i.e., proposed disposition not specified in Reuse Plan): Structures 143, 146, 149, 230, 233, 238, 240, 242, 608, and 609. This restriction applies to the following structures planned for reuse: Structures 77,128,131,144,145,148,160, 202, 208, 256, 257, 502, 503, 504, and 594. 4.8 Indoor Air Quality Notifications VOCs have been identified or may be present in soil or groundwater and may affect indoor air quality in existing buildings or newly constructed buildings located in the following areas: • CO -5 resulting from IRP -11, .IRP -12, IRP -13S, IRP -13W, IRP -16, mingled plume area, and UST 222 (MTBE Plume); - • CO -6 from IRP -3; • CO -7 from IRP -5N; • CO -8 from Mooring Pads 4 and 5; • CO -9 from IRP-5S(a); • CO -10 from IRP -1; and • CO -11 from AST -194A and B. No buildings are present in CO -7 (IRP -5N), CO -9 (IRP-5S[a]), CO -10 (IRP -1), and CO -11 (AST -194A and B). Restrictions The FS for OU -1B evaluated the possible volatilization of VOCs from contaminated groundwater associated with the IRP -3 and IRP -12 plumes. The FS determined that the inhalation exposure pathway for human receptors did not present a significant risk (BNI 2002a). Therefore, no restrictions due to indoor air quality are necessary for buildings impacted by IRP -3 (CO -6) or IRP -12 (portions of CO -5). No data has been collected or risk evaluation conducted on indoor air within buildings potentially impacted by IRP -1, IRP -5N, IRP-5S(a), IRP -11, IRP -13S, IRP -13W, IRP -16, the mingled plume area (related to various AOCs), the MTBE plume (related to UST 222), FOSL 3, MCAS Tustin 25 April 2002 the area impacted by AST -194A and B, and Mooring Pads 4 and 5. Therefore, the following restrictions shall apply to existing buildings or newly constructed buildings situated above or within 100 feet of areas with VOC groundwater contamination plumes based on configurations at the time of construction and/or above areas with VOC soil contamination: • Access or occupancy shall be prohibited with the exception of short-term tours and emergency maintenance conducted with prior DON notification and approval. • To remove this restriction, the lessee may conduct air monitoring within the building following all federal, state, and local regulatory requirements, to determine the suitability of air quality relative to the proposed use of a particular building. Removal of this use restriction will be determined after review and approval of DON and the BCT of an indoor air report submitted by the lessee, or upon DON and BCT concurrence that restrictions for indoor air quality are no longer necessary. These restrictions are applicable to CO -7, CO -8 CO -9, CO -10, CO -11, portions of CO -5, and to the following existing buildings: Buildings 3, 4,13,16,19, 20A, 21, 26, 28, 28A, 30, 35, 35A, 40A, 47, 49, 71A, 71B, 71C, 71D, 71E, 71F, 71H, 71J, 86,87f 88,92.,161,163,,165,166,167,168,,173,178,185.,189,199,f 207, 221, 228, 253, 258, 260, 263, 300, 303, 505, 506, 509, 511, 547, 577, and 3005T. 4.9 Lead -Based Paint DON policy for residential buildings is contained in the joint U.S. EPA/DoD interim final Lead -Based Paint Guidelines for Disposal of Department of Defense Residential Real Property (DoD 1999). The following sections summarize specific notifications and restrictions regarding the presence of LBP in some of the buildings/ structures located within the CO areas. Notifications Notifications of potential LBP at buildings and structures within the CO areas are based solely on the age of construction (i.e., constructed before the Consumer Product Safety Commission's 1978 ban on lead-based paint for residential use). Ninety-eight buildings and structures within the CO areas were built prior to 1978 and may contain LBP. Table 1 provides a list of all buildings and structures within the CO areas and their corresponding dates of construction. FOSL 3, WAS Tustin 26 April 2002 Restrictions The prospective lessee will be required to comply with the specific restrictions listed below and additional environmental lease provisions substantially similar to those provided in Attachment 3 (Section 13.12). The buildings and structures within the CO areas have been separated into two categories based on proposed disposition to assist in determining the restrictions associated with LBP: a) Buildings/ structures built prior to 1978, and b) buildings/ structures built after 1978. (a) Buildings/Structures Built Prior to January 1, 1978 (i) Proposed for Reuse • Buildings/ structures may be used for residential use or child -occupied facilities only after the lessee conducts the necessary LBP surveys and abatement in accordance with all local, state, and federal requirements. Residential or child - occupied use of these buildings/ structures will be subject to approval of DON .and the BCT. These restrictions are applicable to the following buildings and structures: Buildings C-4, 2, 3, 86, 87, 88,134,159,161,165,166,167,168,173,199, and 300 and Structures 77,128,131,144,145,148,160, 202, and 208. (ii) Proposed for Demolition or TBD • Buildings/ structures may be used for residential use or child -occupied facilities only after the lessee conducts the necessary LBP surveys and abatement in accordance with all local, state, and federal requirements. Residential or child - occupied use of these buildings/ structures will be subject to approval of DON and the BCT. • The lessee shall be responsible for demolishing buildings/ structures in accordance with applicable local, state, and federal regulatory requirements. The lessee shall be responsible for conducting post -demolition soil sampling and abatement of soil -lead hazards. These restrictions are applicable to the following buildings and structures: Buildings C-3,1,4, 10G, 13,16,17,19, 20A, 20B, 21, 26, 27, 28, 28A, 29, 29A, 30, 35, 35A, 40A, 40B, 41, 42, 47, 49, 53, 66, 71A, 71B, 71C, 71D, 71E, 71F, 71G, 71H, 71I, 71J, 89, 90, 92, 93,103,163,171,174,175,178,179,183,185,186,187,189, 201, 207, 216, 221, 303, 306, and 3000T, and Structures 11, 12, 106, 143, 146, 149, 150, 230, 233, 238, 240, 242, 608, and 609. FOSL 3, MCAS Tustin 27 April 2002 (b) Buildings/Structures Built After January 1, 1978 There are no restrictions due to LBP for buildings/ structures constructed after 1978. This is applicable to the following buildings/ structures: Buildings 17T, 47T, 226, 228, 247, 248, 253, 258, 259, 260, 261, 262, 263, 264, 265, 266, 505, 506, 507, 509, 511, 512, 513, 514, 515, 523, 533, 539, 547, 564, 576, 577, 578, 579, 580, 587, 588, 589, 596, and 3005T and Structures 203, 204, 256, 257, 502, 503, 504, 541, 542, and 594. 4.10 Polychlorinated Biphenyls Notifications The presence of known PCBs is summarized below and identified in Table 3. Copies of PCB survey reports will be included in the lease documentation. An inventory of PCB items and equipment at MCAS Tustin was conducted in 1992 (Kennedy/Jenks Consultants 1992). Seven items (five small capacitors and two cut-out switches) were identified as possibly containing PCB insulation fluid or solid insulation (Table 3). The cutout switches were dismantled and removed. Corrective action was not conducted or required for the five remaining items because observation and/or sampling were not possible without dismantling the motor and destroying the capacitor. However, the 5 small capacitors may contain PCB -impregnated solid insulation. If the lessee finds equipment containing 50 or more parts per million (ppm), the PCB small capacitors in those motors should be processed/ disposed of as regulated items. PCB -containing equipment may also be subject to State hazardous waste laws regulating PCB waste. Fluorescent light fixtures were not included in the PCB items and equipment survey. Because several buildings were built before 1979, it is assumed that some light ballasts in the buildings may contain PCBs. Fluorescent light ballasts manufactured before 1979 often contain PCB small capacitors that may be disposed as municipal solid waste. No action is required at the buildings unless large quantities of PCB -containing fluorescent light ballasts are removed. According to DON guidance on disposal of fluorescent light ballasts containing PCBs (DON 1989), large quantities of PCB small capacitors generated from fluorescent light ballasts, such as when the fixtures in a large office or an entire building are replaced, should be disposed as regulated PCB equipment. Fluorescent light ballasts that contain PCBs have approximately 1.0 to 1.5 ounces of PCB fluid in each capacitor. There are approximately 3.1 to 4.7 pounds of PCB fluid for every 50 PCB small capacitors in fluorescent light ballasts. If the lessee plans to dispose fluorescent light ballasts containing 3 or more pounds of PCB fluid, they should be processed as regulated items. FOSL 3, MCAS Tustin 28 April 2002 In 1996 a PCB transformer survey was conducted at MCAS Tustin (PWC 1996). Per federal regulations (40 Code of Federal Regulations 761.3), transformers with PCB concentrations less than 50 ppm are classified as non -PCB transformers. However, equipment containing equal to or greater than 50 and less than 500 ppm PCBs is considered PCB -contaminated electrical equipment. PCB -containing equipment may also be subject to State hazardous waste laws regulating PCB waste. All transformers containing PCBs at concentrations of 50 ppm or more have been replaced. Other transformers within the CO areas that had concentrations of PCBs less than 33 ppm are still present in the CO areas. As these transformers are considered non -PCB containing transformers, additional action concerning these transformers is not required before lease or transfer. Restrictions There are no restrictions due to PCBs. 4.11- Radon DoD policy with respect to radon is provided in Attachment 6. Notifications Although not required by regulatory agencies, DON conducted a radon survey at the housing areas of MCAS Tustin in 1991. Radon screening results were based on a representative sampling of residential buildings in CO -5. The results of the radon survey indicated that none of the residential buildings contained levels of radon above 4 picocuries per liter (pCi/ L). According to U.S. EPA guidance, radon at levels of 4 pCi/L or less are considered "low risk," and no mitigation is required (Bufton 1991). Restrictions There are no restrictions due to the presence of radon. 4.12 Groundwater Use/Subsurface Excavation The following discussion summarizes required notifications and restrictions relating to groundwater use and subsurface excavation within the CO areas. Notifications As noted in Section 3, VOC-contaminated groundwater exists beneath all CO areas Assessments and remediation activities are ongoing and contamination impacts to groundwater are currently being evaluated. FOSL 3, MCAS Tustin 29 Apri12002 Restrictinnq • To address potential risks associated with potential or identified soil and/or groundwater contamination, the lessee cannot excavate, dig, drill, or otherwise disturb soil or extract, use, or access groundwater beneath the CO areas without obtaining prior DON and BCT approval (see Attachment 3 - Sections 13.11 and 13.16 for applicable model lease provision). • Until remedial activities are completed and regulatory concurrence for no further action is achieved, the lessee may not conduct any construction activity that involves excavation of soil without prior approval from DON and the BCT. The lessee must demonstrate to DON and the BCT that these activities will not interfere with or adversely affect DON response action(s) for the IRP sites, AOCs and/or UST/ AST sites and that human health and the environment will be adequately protected. No subsurface activities will be conducted until prior approval is obtained from DON and the BCT. • Removal of this use restriction based on groundwater and soil contamination will be determined upon DON and BCT concurrence that groundwater use and subsurface excavation restrictions are no longer necessary. These restrictions apply to all seven CO areas. 4.13 Historic Property Notifications The blimp hangars (Buildings 28 and 29) and their associated helium tank buildings (28A and 29A) are located within the boundaries of CO areas 5 and 6. The hangers were constructed in 1943 and are considered landmarks in Orange County. The hangars were listed on the National Register of Historic Places in October 1974. The National Historic Preservation Act, as amended, directs federal agencies to assume responsibility for the preservation of historic properties owned or controlled by the agency. In a letter dated 28 June 1996, the State Historic Preservation Officer (SHPO) concurred with the United States Marine Corp's determination that these hangars and helium tank buildings are eligible to be listed on the National Register of Historic Places. A Section 106 Consultation has taken place at MCAS Tustin, and it resulted in a Memorandum of Agreement (MOA) signed by the DON, the SHPO, the Local Redevelopment Authority (LRA), and the Advisory Council on Historic Preservation for the Disposal and Reuse of MCAS Tustin. A copy of the MOA will be attached to the lease documentation for these buildings. FOSL 3, WAS Tustin 30 April 2002 RentrictinnS The MOA, issued on 16 December 1999 (DON 1999b), outlines measures to reduce, avoid, or mitigate adverse effects on Buildings 28, 28A, 29, and 29A. The MOA states that a substantive effort must be made to determine whether there is an economically viable adaptive use of the Hangar 28 Complex (Buildings 28 and 28A) and the Hangar 29 Complex (Buildings 29 and 29A) and provides guidelines for the marketing effort. The MOA also includes an Architectural Preservation Covenant to be included as a deed covenant in the event that a viable reuse is identified. If no viable reuse is identified, then the mitigations indicated in the MOA must be completed. This restriction applies to the following buildings: Buildings 28, 28A, 29, and 29A. 4.14 Prime/Unique Farmland Notifications Prime farmland is present on Parcels 16, 17, 24, and 27. Portions of these parcels are contained in CO -5, CO -6, and C,0-8. According to the final MCAS Tustin EIS/EIR, no mitigation measures are required (DON 1999a). Restrictions There are no restrictions due to prime/ unique farmland 4.15 Wetlands Notifications CO -7 and CO -9 contain drainage facilities (IRP -5N and IRP-5S[a])that have been designated as jurisdictional waters (wetlands) of the United States under Section 404 of the Clean Water Act. The United States Army Corps of Engineers exerts jurisdiction over waters of the United States, which includes territorial seas, tidal waters, and nontidal waters. IRP -5N and IRP-5S(a) support cattail and other common marsh vegetation. The water source appears to be urban and agricultural runoff from both on- site and off-site sources. Restrictions • Development by the lessee in CO -7 and CO -9 that may impact these wetland areas will require Section 404 permit(s) (DON 1999a). All development in CO -7 and CO -9 will require consultation with the United States Army Corps of FOSL 3, MCAS Tustin 31 April 2002 Engineers to determine whether Section 404 permit(s) are required. Documentation of Section 404 permit(s) or non -applicability shall be presented to DON and the BCT for approval prior to development within these CO areas. This restriction applies to CO -7 and CO -9. 4.16 Monitoring Wells Notifications CO -5, CO -6, CO -7, CO -8, and CO -9 contain monitoring wells and/or surface water gauging locations that are periodically monitored as listed in Table 6. CO -10 contains monitoring wells, surface water gauging locations, landfill gas monitoring probes, and their associated equipment (e.g. french drain system, survey monuments, sumps, signs, fencing) that are periodically monitored as listed in Table 6. ReStrictinm • These monitoring wells, surface water gauging locations, and their associated equipment shall not be altered, disturbed, or removed without the prior review and approval of DON and the BCT. This restriction is applicable to CO -5, CO -6, CO -7, CO -8, CO -9, and CO -10. 4.17 School Site Considerations Notifications Parcels 1, 2,17,19 and 20 have been proposed in the Reuse Plan for educational use. Should the subject parcel be considered for the proposed acquisition and/or construction of school properties utilizing state funding, a separate environmental review process in compliance with the California Education Code section 17210 et. seq. will need to be conducted by the lessee and approved by the DTSC (School Property Evaluation and Cleanup Division). The California Education Code requires that a comprehensive evaluation of natural and manmade hazardous materials be conducted for school properties. This comprehensive evaluation requires additional investigation of hazardous materials outside the scope of CERCLA hazardous substances. This additional evaluation includes: legally applied pesticides and herbicides, imported fill materials, naturally occurring hazardous substances such as heavy metals (e.g., chromium, mercury, nickel), metalloids (e.g., arsenic, selenium), gases (e.g., methane, hydrogen sulfide), and radioactive elements (e.g., radon gas) and naturally occurring petroleum deposits. The evaluation also includes asbestos -containing materials and lead-based paint at concentrations that fall outside the scope of CERCLA. FOSL 3, MCAS Tustin 32 April 2002 Any requirements associated with the evaluation of the proposed school site for compliance with the California Education Code are the sole responsibility of the lessee. Restrictions There are no restrictions due to future school sites. FOSL 3, MCAS Tustin 33 April 2002 This page intentionally left blank.

WIMS-01, and MWA-03 at MCAT Tustin in Orange County, California. The remedial action was developed in accordance with the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980, as amended by the Superfund Amendments and Reauthorization Act of 1986 and, to the extent practicable, the National Oil and Hazardous Substances Pollution Contingency Plan. This Record of Decision (ROD)/Remedial Action Plan (RAP) has also been, prepared in accordance with California Health and Safety. Code Section 25356.1.- This action is based on the administrative record file for these sites/AOCs. The state of California (through the California Environmental Protection Agency Department of Toxic Substances Control [DTSC] and Santa Ana Regional Water Quality Control Board [RWQC]3]) and the United States Environmental Protection Agency (U.S. EPA) agree on the selected remedy. DESCRIPTION OF THE SELECTED REMEDY: NO ACTION No action is the selected -remedy- for IRP -2, IRP -9, and MP -13E and ADCs AD -04, AS. -06, AS -08, AST -02, AST -04, MDA -04, MDA -07, MMS -01, and MWA-03. In selecting the no action remedy for these sites/AOCs, the Department of the Navy (DON) has determined that the existing condition of the sites/AOCs is protective of human health and the environment. Removal actions were conducted at MWA-03, IRP -2, IRP -9A, and IRP -913. Tlie Resource Conservation and Recovery Act action at MNNIA-03 took place in December 1997 and involved the excavation, transport, and treatment of 285 tons of total petroleum hydrocarbon (TPH)- and polynuclear aromatic hydrocarbon (PA I) -contaminated soil using an on-site thermal desorption unit. The non -time -critical removal action of soil at TRP -2 took place in May 1997. This action involved excavation and treatment of approximately 569 tons of PAH -contaminated soil. A non -time -critical removal action was conducted at IRMA between 10 July and 04 Scptember 1997 and at IRP -9B between 14 October 1998 and 05 January 1999. The actions at IRP -9A and IRP -913 involved excavation and treatment of approximately 700 and 6,827 tons of TPH- and Final ROD/RAP - OU -2 No Action Sites and Areas of Concern, MCAF Tustin page 1 09107/00 7:sa AM SaM i:►worC,-proces�np4epon:�eto1� I Vvd�ou.2%finaM000161a.doe HHK 1b 2002 11:36 FR SWDIV MC BRAC Date: 07/10/00 619 532 0790 TO 9916582689677 P.02i06 Declaration PAH -contaminated soil, respectively. Human -health risk assessments were performed to evaluate the risks remaining after the removal actions at MWA-03, IRP -02, IRP -9A, and IRP -9B. These assessments showed that the postremoval condition at each site/AOC is protective of human health and the environment. Soil and groundwater at each of the sites and ADCs included in this OU -2 ROD/RAP were evaluated and were determined to require no further action due to site-specific releases. However, IRP -9, AS -08, MDA -04, and MDA -07 are located near large volatile organic compound plumes that originate from three OU -1 sites (IRP -3, IRP -12, and IRP -13S). Therefore, groundwater at IRP -9, AS -08, MDA -04, and MDA -07 is being addressed as part of the OU -1 remedial action: The need for groundwater cleanup at IRP -9 and AS -08, MDA -04, and MDA -07 will be evaluated in conjunction with remedial action at OU -1 and will be documented in. a separate ROD/RAP. DTSC, RWQCB, and U.S. EPA agree with this approach. No monitoring or deed restrictions are required to address chemicals present in soil and/or groundwater as a result of operations at the no action sites/AOCs. However, use restrictions may be required as part of potential remedial actions associated with -OU-1. The need for such restrictions Will be addressed in the proposed plan and ROD/RAP for OU -1. The property containing IRP -9, AS -08, MDA -04, and MDA -07 will not be transferred until the evaluation of OU -1 is complete and remedial action is finalized unless an -early transfer is pursued. Institutional controls are anticipated and will be developed in conjunction with' an Environmental Restriction Covenant and Agreement. When the Environmental Restriction Covenant and Agreement is finalized, it will be executed by the state and the federal government contemporaneously with the negotiation and execution of the conveyance of the property to the transferee(s) by deed, pursuant to the Defense Base Closure and Realignment Act of 1990, 10 United States Code Section 2687 note. DECLARATION STATEMENT. The DON has determined that no remedial action is necessary to ensure the protection of human health and the environment at IRP -2, IRP -9, and IRP -13E and ADCs AD -04, AS -06, AS -08, AST -02, AST -04, MDA -04, MDA -07, MMS -01, and MWA-03. This determination was based on extensive field investigations, laboratory analyses, and a thorough assessment of potential human -health risks at each location. Ecological risk assessments were not performed at these sites/AOCs because habitat surveys performed in October and November 1994 and February 1995 showed that there is no suitable wildlife habitat present (BNI 1996i;j). The results of the human -health risk assessments of these sites/AOCs show that the chemicals present at the sites/AOCs do not present an unacceptable risk to human health or the environment. Therefore, no remedial action is required at these sites/AOCs. Because hazardous substances are not present at concentrations above unacceptable levels, CERCLA Section -121 cleanup standards do not apply. page 2 Final ROD/RAP -- OU -2 No Action Sites and Areas of Concern.

Enclosed is the Case Closure Summary for the referenced site for your records. Five direct -push soil barings were drilled to depths of 21 to 25 feet and soil samples were collected. Soil with a strong hydrocarbon odor was found between 1 to 7 feet below the surface. Soil samples were analyzed for total recoverable petroleum hydrocarbons (TRPH) by EPA Method 418.1, lead by Method 6010A, and volatile organic compounds (VOC) by Method 8240. TRPH and lead were detected in the soil samples. Temporary wells were installed and groundwater samples were collected and analyzed by the same methods as the soil. Minor concentrations of lead, 1, 2-dichloroethene, and trichloroethene were detected in the water samples collected from boring 185A. Analytical results for the other two samples were non -detect. Petroleum contaminated soil was excavated and transported to the on-site thermal desorption unit. Confirmation soil samples were collected and analyzed for BTEX and MTBE (EPA Method 8020) and total petroleurih hydrocarbons (EPA method 8015m).

As you may recall, these policies were drafted and accepted within the Defense Environmental Seatrity Council (DESC) structure. During its May 6, 1994, meeting the DESC accepted the drift DoD policy on radon at BRAC properties. At that meeting, the draft policies on asbestos and lead paint were refrsred to the Environment, Safety and Occupational Health Policy Board (ESOUPB) for envision and ncieptanae. During its May 10, 1994, ttmeting the ESOAPB accepted the revised draft DoD policies on asbestos and lead paint at BRAC properties. Subsequent to DESC and ESOHPB action, these polices were coordinated formally with the Assistant Secretary of Defense (Economic Security) and the Office of the Deputy General Counsel (Acquisition & Logistics).

Therefore, unless it is determined by competent authority that the ACM in the property does pose a threat to human health at the time of transfer, all property containing ACM will be conveved, leased, or otherwise disposed of as is through the Base Realignment and CIosure (BRAC) process. Prior to property disposal, all available information on the existence, extent, and condition of ACM shall be incorporated into the Environmental Baseline Survey (EBS) report or other appropriate document to be provided to the transferee. The survey report or document shall include: reasonably available information on the type, location, and condition of asbestos in any building or improvement on the property; any results of testing for asbestos; a description of any asbestos control measures taken for the property; any available information on costs or time necessary to remove all or any portion of the remaining ACM; however, special studies or tests to obtain this material are not required; and — results of a site-specific update of the asbestos inventory performed to revalidate the condition of — ACM. Asbestos -containing material shall be remedied prior to property disposal only if it is of a type and condition that'is not in compliance with applicable laws, regulations, and standards;: or if it poses a threat to human health at the time of transfer of the property. This remediation should be accomplished by the active Service organization, by the Service disposal agent, or by the transferee under a negotiated requirement of the contract for sale or lease. The remediation discussed above will not be required when the buildings are scheduled for demolition by the transferee; the transfer document prohibits occupation -of the buildings prior to the demolition; and the transferee assumes responsibility for the management of any ACM in accordance with applicable laws.

The attached Field Guide is a joint DoD and Environmental Protection Agency (EPA) guidance document for use by DoD and EPA personnel in the evaluation and control of lead-based paint at DoD residential real property scheduled for disposition under the base realignment and closure (BRAC) program. Lead-based paint requirements are defined by Title X, the Residential Lead -Based Paint Hazard Reduction Act of 1992, which amended the Lead -Based Paint Poisoning Prevention Act (42 U.S.C, Section 4822) and its implementing regulations (under the EPA Toxic Substances Control Act (TSCA) Section 403 rule and the Department of Housing and Urban Development (HUD) Section 1013 rule). DoD will issue separate policy on lead-based paint requirements for transferring non-residential properties. The Field Guide provides a general roadmap summarizing the requirements for the evaluation and control of lead-based paint hazards in target housing as defined by Title X and TSCA. In addition to existing Title X requtretncnts, the Field Guide also specifies some actions that exceed Title X requirements. These actions represent DoD's desire to go beyond actions strictly required by law to ensure that activities taken in this regard are protective of human health and the environment. DoD policy is to: Abate soil -lead surrounding housing constructed between 1960 and 1978 (Title X requires abatement of lead-based paint hazards in target housing constructed prior to 1960). The transfer agreement may require the purchaser to perform the abatement activities. Evaluate the need for interim controls, abatement, or no action for bare soil lead concentrations between 400 and 2000 ppm (excluding children's play areas) based on the findings of the lead-based paint inspection, risk assessment, and criteria contained in the Field Guide.

Defending Our Future APR 25 21302 18:43 FR SWDIU MC BRAC 619 532 0780 TO 9918582683677 P.03/03 •► Evaluate and abate lead-based paint hazards in structures reused as child -occupied facilities located on residential real property. Child -occupied facilities are day care centers, preschools, and kindergarten classrooms visited regularly by children under six years of age. Evaluate and abate soil -lead hazards for target housing demolished and redeveloped for residential use following transfer. Under Title X, residential dwellings that are demolished or not intended for occupancy after transfer do not require an inspection and risk assessment or lead-based paint control and hazard abatement. However. Dol) requires that the terms of property transfer include a requirement for the transferee to evaluate and abate any soil -lead hazards prior to occupancy of any newly constructed dwelling units. By adding these additional measures as a matter of policy, DoD believes it exceeds measures necessary to reduce potential lead exposures in children and will significantly contribute to the elimination of adverse effects in children from exposures to lead from lead-based paint in federally -owned target housing subject to disposition. This lead-based paint policy supersedes the DoD 31 October 1994 lead-based paint policy attached to the PADUSD (ES) memorandum, Asbestos, Uad Paint, and Radon Policies at BRAC Properties. The asbestos and radon policies referenced in the memorandum rernain in effect. Property transfer agreements executed under the previous policy are not required to meet these requirements. The effective date implementing thes6 requirements is 30 March 2000. ShLvrri W. Goodman Deputy Under Secretary of Defense (Environmental Security) Attachment Policies on Asbestos, Lead -Based Paint, and Radon at BRAC Properties DOD POLICY ON RADON AT BASE REALIGNMENT AND CLOSURE PROPERTIES In response to concerns with the potential health effects associated with radon exposure, and in accordance with the Indoor Radon Abatement provisions of Subchapter III of the Toxic Substances Control Act, 26 U.S.C. 2661 to 2671, the Department of Defense (DoD) conducted a study to determine radon levels in a representative sample of its buildings. In addition, as part of DoD's voluntary approach to reducing radon exposure. DoD has applied the Environmental Protection Agency (EPA) guidelines for residential structures with regard to remedial actions. DoD policy is to ensure that any available and relevant radon assessment data pertaining to Base Realignment and Closure (BRAC) property being transferred shall be included in property transfer documents. DoD policy is not to perform radon assessment and mitigation prior to transfer of BRAC property unless otherwise required by applicable law.

Forman BRAC Environmental Coordinator Naval Facilities Engineering Command BRAC Program Office 1230 Columbia Street, Suite 1100 San Diego, California 92101-8517 :. Gray Davis Governor FINDING OF SUITABILITY TO LEASE (FOSL) FOR CARVE -OUT AREAS 5, 6, 7, 8, 9, 10, AND 11, MARINE CORPS AIR STATION (MCAS) TUSTIN, TUSTIN, CALIFORNIA Dear Mr. Forman: On April 23, 2002, the Department of Toxic Substances Control (DTSC) received electronic versions of the revised text, tables and response to comments for the subject document, also known as FOSL 3. The revised text is postdated April 25, 2002. Subsequently, DTSC received electronic versions ofrevised text for indoor air quality (Section 4.8) on April 25, 2002, and Carve -Out Area 8 (Section 3.2.4) and monitoring wells (Section 4.16) on April 26, 2002. Based upon review of the revised text, tables and response to comments, DTSC comments forwarded on April 15 and 17, 2002 have been adequately addressed. The purpose of this FOSL is to document the conclusion that the property identified above is suitable for lease by a lease in furtherance of conveyance. This FOSL includes carve -out (CO) areas associated with the Finding of Suitability to Transfer for Parcels 23, 29, 34, 35, and 36 and Portions of 1, 16, 17, 24, 27, 28, 40 and 41, Marine Corps Air Station Tustin, .California (FOST 3) was finalized on April 22, 2002. The CO areas encompass seven areas with ongoing environmental investigations or response actions. The energy challenge facing California is real. Every Californian needs to take immediate action to reduce energy consumption. For a list of simple ways you can reduce demand and cut your energy costs, see our Web -site at www.dtsc.ca.gov. 8 Printed on Recycled Paper Mr. Keith S. Forman April 26, 2002 Page 2 DTSC concurs that the property associated with FOSL 3 can be leased with the specified conditions, notifications and restrictions in a manner that is protective of human health and the environment. Please note that for a majority of parcels, the specified ultimate use cannot be implemented until the restrictions have been removed, conditions have been met or notifications have been followed. Although DTSC is concurring on this FOSL, potential school sites and lead-based paint (LBP) may be issues for future transfer of property associated with some of the CO Areas. Potential school sites may be an issue for the future transfer of CO Area 5 (CO - 5). For transfer, DTSC will evaluate the suitability to transfer the property associated with CO -5 for the intended use. Several Parcels included in CO -5 are identified for educational/recreational use. DTSC concurrence on a FOST for these parcels will be dependent upon attainment of cleanup goals for residential use and the completion of a separate environmental review for school sites. The. FOSL identifies the ultimate use of Parcels 1, 2, 17, 18, 19, 20 and 22 as educationallrecreational that may include school sites, meaning kindergarten through grade 12 (elementary, middle and high schools). Should the subject parcels be considered for the proposed acquisition and/or construction of school properties utilizing state funding, a separate and comprehensive review pursuant to the California Education Code, section 17210 et seq., is required. The California Education Code requires that DTSC make a determination as to the suitability for school use based on this review. In addition to attainment of cleanup goals for residential use, if this requirement is not met, DTSC will not concur with the finding of suitability to transfer. Notification of potential LBP was provided based solely on the date of construction. As a result, there are 98 buildings and structures within the CO areas (CO -5, CO -6 and CO -10) that were constructed prior to 1978, the year when LBP products were discontinued. Based on the date of construction, LBP may be present on these buildings. Residential or child -occupied use of these buildings/structures is restricted. As a result, DTSC agrees that the buildings and structures can be leased, with the restrictions, in a manner that is protective of human health and the environment. However, LBP may be an issue for the future transfer of CO -5, CO -6 and CO -10. DTSC maintains that any lead released to soil from LBP is a release pursuant to the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) as amended by the Superfund Amendments and Reauthorization Act (SARA) of 1986. The surfaces of buildings and structures constructed prior to 1978 may have LBP that could be released to soil. DTSC will have to determine whether, pursuant to CERCLA 120(h)(3), all actions have been taken at CO -5, CO -6 and CO -10 to remedy potential releases of lead to the environment from LBP. Based on this determination, DTSC will decide if property associated with CO -5, CO -6 and CO -10 is suitable for transfer. Mr. Keith S. Forman April 26, 2002 Page 3 Please ensure that the revised text, tables, response to comments and all attachments are incorporated into the final version of the document.
