Surrounding Zoning Project Description The applicant, Ryan Gatchalian, is requesting authorization for soil remediation activity associated with the former dry-cleaning use at RH Cleaners to excavate soil impacted by tetrachloroethene (PCE) and trichloroethene (TCE).Tetrachloroethene (PCE) was the primary solvent used during dry cleaning operations until the transition to a non-PCE based system in 2003. Actual remediation activities are required and monitored by County of Orange Health Care Agency (OCHCA) Hazardous Materials Division and the Santa Ana Regional Water Quality Control Board (SARWQCB). 2 ZA Item #1 December 14, 2023 CUP 2023-0020 "T, Page 3 Conditional Use Permit In accordance with Tustin City Code (TCC) Section 9270(a)(3)(d), the removal of earth, other than in connection with construction of buildings, roadways, or public or home improvements, is allowed with approval of a Conditional Use Permit (CUP). Pursuant to TCC Section 9299(b)(4)(a), the Zoning Administrator is authorized to consider specified development applications for soil remediation activities. Soil Remediation Process According to the Soil Excavation Work Plan (Attachment A) prepared by Geosyntec Consultants, dated July 29, 2022, and approved by SARWQCB, the proposed soil remediation would primarily focus on excavation of the interior of the existing 1,800 square foot vacant tenant suite. Excavated soil will be stockpiled under and on plastic sheeting and soil samples will be collected for further testing. In accordance with South Coast Air Quality Management District (SCAQMD) requirements, the contaminated soil will be disposed of at an approved treatment/disposal facility within 30 days of soil stockpiling. The excavation area will be backfilled in accordance with City requirements and all applicable regulations. Project Proposal Approximately 54 cubic yards (CY) of impacted soil are planned to be excavated to an approximate depth of 5 feet below ground surface (bgs) confined to the area within the currently vacant project site, as highlighted in Figure 2 below. The concrete slab in the excavation area will be saw-cut and removed prior to excavation and saw cuts will be a minimum of 18 inches from the building walls. The estimated total volume of potentially PCE- and TCE-impacted soil is approximately 1,450 cubic feet, 54 CY or 81 tons. The total estimated volume of impacted soil and cut soil to be excavated is approximately 104 CY (54 CY of impacted soil and 50 CY of cut material for sloping). 3 ZA Item #1 �V � December 2023 "T, CUP 2023-000020 I �J Page 4 qp.

Excavation Area (highlighted) Based on the site access conditions, it is anticipated that the excavation will be conducted using a limited access excavator, and excavated soil will be stockpiled on plastic sheeting behind the building to the northwest within a fenced area. The contractor will be responsible for selecting and implementing the most effective excavation, backfill, and hauling methods/equipment. The excavated area will be backfilled with a combination of CLSM slurry (to facilitate slot-cutting) and compacted crushed stone, and the slab will be restored as shown on the excavation design plans (see Attachment A). As indicated above, the applicant will work with the City of Tustin for scheduling the appropriate inspections. At the end of each workday, all stockpiles will be completely covered, and the covers securely anchored. In accordance with SCAQMD requirements, a photoionization detector (PID) will be used to monitor and record volatile organic compound (VOC) emissions from excavated materials at regular intervals (at least every 15 minutes). PID measurements will be monitored while slowly moving the probe across the stockpile surface. If a PID reading above background levels is observed, the excavated materials will continue to be monitored until the maximum reading is obtained. The PID shall be paused at this Location for a duration of at least two instrument response times. The PID measurement will then be recorded on designated field forms or in the field logs. 4 ZA Item #1 December 14, 2023 CUP 2023-0020 "T, Page 5 Soil samples from stockpiles will be analyzed by Environmental Protection Agency (EPA) methods to determine levels and type of contamination in each stockpile. The soil disposal facility will be selected at time of waste disposal depending on the type of analyzed contaminates present in soil samples. The contractor will backfill excavated soil area with certified-clean CLSM and compacted crushed stone. Proper documentation must be provided and approved by the client or client representative prior to it being delivered to the Site. The contractor will construct the replacement slab according to the excavation design plans provided in Attachment A. Environmental Analysis Pursuant to Section 15330 (Class 30) of the Guidelines to the California Environmental Quality Act (CEQA), minor actions to prevent, minimize, stabilize, mitigate, or eliminate the release or threat of release of hazardous waste or hazardous substances which are small actions costing one million dollars or less are categorically exempt from the provision of CEQA. The exemption specifically includes excavation and/or off-site disposal of contaminated soils in regulated units. The proposed project falls within the categorical exemption for such cleanup actions. CONCLUSION: Analysis of CUP 2023-0020 has determined that the establishment and operations of temporary soil remediation activities is consistent with TCC Section 9270(a)(3)(d), TCC Section 9299(b)(4)(a), and TCC Section 9291(c). Findings to support the request have been included in ZAA No. 23-008. Based on this report, the findings and Conditions of Approval contained in ZAA 23-008, staff recommends that the Zoning Administrator adopt ZAA 23-008 approving CUP 2023-0020 to authorize the establishment and operations of temporary soil remediation activities located at 14591 Red Hill Avenue.

(Geosyntec) has prepared this Soil Excavation Work Plan (Work Plan), on behalf of Red Hill Village, LLC, for the property located at 14591 Red Hill Avenue in Tustin, California (Site). The Site location is shown in Figure 1. This Work Plan presents the scope of work and methodology for excavation of soil impacted by tetrachloroethene (PCE) and trichloroethene (TCE) beneath the Site building. Investigation of the extent of PCE and TCE impacts to Site soil was documented in the Source Area Characterization Report (Report) [Geosyntec, 2022]. Santa Ana Regional Water Quality Control Board (SARWQCB) approved the Report via email on April 28, 2022, and requested that a work plan for soil excavation be submitted by June 16, 2022. Geosyntec requested an extension of the deliverable due date to July 29,2022,which was granted by SARWQCB via email on June 15, 2022. 1.1 Proiect Overview Approximately 54 cubic yards (CY) of impacted soil is planned to be excavated to an approximate depth of 5 feet below ground surface (bgs) based on the extent of impacts described in the Report, as well as the practical limitations imposed by working within the small suite (approximately 1,800 square feet) and in close proximity to building foundations. The approximate extent of the impacted soil area is presented in Figure 2, and the excavation plans are provided in Appendix A. Geosyntec is serving as the engineer (Engineer) for this proposed soil excavation. It is anticipated that a contractor(Contractor)will be engaged to conduct the actual excavation activities. 1.2 Plan Organization This Work Plan is organized into the following Sections: • Section 2, Background, includes information on the Site, surrounding properties and nature of impacts; • Section 3, Scope of Work, presents details on the specific work tasks for the excavation activities; • Section 4, Contractor Considerations, presents a list of tasks and requirements for the Contractor; • Section 5, Reporting and Schedule, includes the anticipated project duration for the excavation effort; and • Section 6, References, includes a list of documents referenced within this Work Plan. RH Cleaners Soil Excavation Work Plan20220729 I July 29,2022 - 9 Geosyntec° consultants 2.0 BACKGROUND The Site is in the southwest corner of the Red Hill Shopping Village in a mixed commercial/residential area of Tustin (Figure 1). The Site is located in the southernmost retail space of a building that contains four suites. The retail space was the location of dry-cleaning operations under ownership of RH Cleaners from the early 1980s until 2016. PCE was the primary solvent used during dry-cleaning operations until the transition to a non-PCE-based system in 2003 [Centec, 2018]. Based on Site investigations,the primary constituents of potential concern (COPCs) include PCE and its degradation by-products TCE, cis-1,2-dichloroethene (cl2DCE), trans-1,2-dichloroethene (tl2DCE), and vinyl chloride (VC). Details of previous investigations and regulatory involvement at the Site are provided in the Vapor Intrusion Sampling and Analysis Work Plan[Geosyntec,2019]. Continuous geologic logging performed by Centec Engineering, Inc. (Centec), and Geosyntec indicates that the subsurface lithology consists of mostly silty clay and clayey sand from ground surface to 8 feet below ground surface(feet bgs),underlain by silty and clayey sand to 10 feet bgs, and by a gravelly sand layer to approximately 15 feet bgs. Deeper sediments consist of mostly silty clay and clayey silt with occasional very thin coarse-grained deposits. A laterally continuous sand zone was observed to begin between approximately 60 to 70 feet bgs. Groundwater was encountered at approximately 55 feet bgs in January 2018 [Centec, 2018] and 45 to 50 feet bgs in May 2022. During the January 2022 soil investigation documented in the Report, PCE and/or TCE exceeded the San Francisco Bay Regional Water Quality Control Board (SFRWQCB) Environmental Screening Levels (ESLs) for commercial soil direct exposure in three of the 33 samples collected (Figure 2). • PCE was detected in HA-4 at 650,000 micrograms per kilogram (µg/kg) and 2,800 µg/kg at 3 and 5 feet bgs,respectively. The detection at 5 feet bgs was just above the commercial ESL of 2,700 µg/kg. TCE was also detected at 30,000 µg/kg at 3 feet bgs at HA-4,which is above the commercial ESL of 6,100 µg/kg. • PCE was detected in HA-8 at 160,000 µg/kg at 3 feet bgs, above the commercial ESL of 2,700 µg/kg. TCE was detected at 26,000 µg/kg in HA-8 at 3 feet bgs, above the commercial ESL of 6,100 µg/kg. Volatile organic compound (VOC) concentrations in additional soil samples exceeded the soil leaching to groundwater ELSs. Boring locations where concentrations of one or more constituents exceeded leaching to groundwater ESLs include: RH Cleaners Soil Excavation WorkPlan_20220729 2 July 29,2022 10 Geosyntec° consultants • HA-4, HA-6, and HA-8: PCE, TCE, and cl2DCE; • HA-7 and HA-9: c 12DCE and VC; and • HA-10: TCE and c12DCE. Concentrations of PCE and TCE were highest at HA-4, located west of vapor extraction well VE1 as shown on Figure 2 RH Cleaners Soil Excavation WorkPlan_20220729 3 July 29,2022 11 Geosyntec° consultants 3.0 SCOPE OF WORK The objective of the proposed scope of work is to remove residual PCE- and TCE- impacted soils that are accessible using a limited access excavator. The scope of work includes the following components: • Submit the excavation plans to the City of Tustin and obtain a permit; • Perform initial marking for Underground Service Alert (USA)/DigAlert and perform geophysical utility locating activities; • Destroy one SVE well (VE-1) and one soil vapor probe (B1) located within the excavation area; • Confirm the location of an existing sewer line along the northwestern boundary of the excavation area and either protect in-place or temporarily remove as necessary; • Saw-cut the concrete slab and excavate both impacted soil and cut soil to allow for sidewall sloping; • Collect confirmation soil samples at the bottom and sidewalls of the excavation area; • Backfill the excavated area with controlled low-strength material (CLSM) and compacted crushed stone; • Place reinforcement and concrete for the replacement slab; and • Dispose of the excavated soil at a licensed disposal facility. 3.1 Pre-Field Activities 3.1.1 Permitting,Health and Safety, and Notifications The excavation design plans will be submitted to the City of Tustin for a building permit following submittal of this Work Plan to SARWQCB. Permits will be obtained from the Orange County Health Care Agency (OCHCA) for the destruction of the SVE well and soil vapor probe within the excavation area. It is anticipated that the chosen Contractor will hold a Rule 1166 South Coast Air Quality Management District(SCAQMD)various locations permit. The Site-specific Health and Safety Plan (HASP) will be reviewed by project personnel prior to beginning Site excavation work. The HASP is included in Appendix B. Site personnel will have 40-hour health and safety training (CFR 1910.120). RH Cleaners Soil Excavation WorkPlan_20220729 4 July 29,2022 12 Geosyntec° consultants The SARWQCB will be notified two weeks in advance of field activities for scheduling purposes. Coordination and inspection with the City of Tustin will be managed in accordance with the terms of the anticipated building permit. 3.1.2 Utility Clearance Prior to beginning excavation activities, the proposed excavation area will be marked with spray paint and USA/DigAlert will be notified at least 48 hours in advance of the field work. Additionally, the excavation area will be surveyed for the presence of buried utilities utilizing standard geophysical techniques. A plumber will be contracted to evaluate a sewer line that runs along the northwestern edge of the excavation. The sewer line will be marked as part of the geophysical clearance and/or plumber evaluation and will be either protected in place or temporarily removed, as appropriate. If necessary,the extent of the excavation may be adjusted to accommodate the sewer line. 3.2 SVE Well and Soil Vapor Probe Destruction Prior to or as part of the implementation of soil excavation, the existing SVE well (VE1) and soil vapor probe(B 1)within the proposed excavation footprint will be destroyed. The soil vapor probe will be over-drilled to total depth, approximately 25 feet bgs, using a limited access direct-push drill rig and backfilled with bentonite cement grout. The well box will be removed as part of the excavation activities. The SVE well will be pressure- grouted with Portland cement grout, and the well box and the top five feet of casing will be removed as part of the excavation in advance of the excavation activities. 3.3 Excavation Activities 3.3.1 Site Preparation Prior to beginning the excavation, the following preparation activities will be completed: • Photographically document the existing condition of the property and nearby structures; • Set up field sanitation facilities, including portable toilet(s) and hand washing station(s). • Mobilize equipment to the Site; • Identify the excavation area boundaries using spray paint; • Delineate exclusion zones,including stockpile areas and decontamination areas; and RH Cleaners Soil Excavation WorkPlan_20220729 5 July 29,2022 13 Geosyntec° consultants • Place temporary fencing and sandbags at the rear parking lot of the Site where temporary stockpiling and storage of equipment is expected to occur. 3.3.2 Soil Excavation, Confirmation Sampling and Backfilling The concrete slab in the excavation area will be saw-cut and removed prior to excavation. Saw cuts will be a minimum of 18 inches from the building walls. The estimated total volume of potentially PCE- and TCE-impacted soil is approximately 1,450 cubic feet or 54 CY or 81 tons (Figure 2). The total estimated volume of impacted soil and cut soil to be excavated is approximately 104 CY(54 CY of impacted soil and 50 CY of cut material for sloping). Based on the site access conditions,it is anticipated that the excavation will be conducted using a limited access excavator,and excavated soils will be stockpiled on plastic sheeting behind the building to the northwest within a fenced area. However, the Contractor will be responsible for selecting and implementing the most effective excavation,backfill, and hauling methods/equipment. Slot excavations will be made on the northwest and northeast borders of the excavation. The slot excavations will be approximately two-feet wide and extend approximately five feet below the slab. These excavations will be filled with CLSM slurry to a depth of 2 feet below the replacement slab, and the final two feet will be backfilled with 1-foot fl- inches of crushed sone and 4 inches of sand. A geotextile layer will be placed between the crushed stone and sand layers and a 10-mil visqueen membrane will be placed in the middle of the sand zone. The remainder of the excavation will extend to a maximum 5 foot depth at a 1:1 slope. Prior to commencing backfilling operations, confirmatory sampling will be performed by the Engineer to document residual concentrations of COPCs that will remain in place. One confirmation sidewall sample will be collected from each of the four sidewalls, and one bottom sample will be collected from the bottom of the excavation. Confirmation soil samples will be submitted to Eurofins Calscience Inc. of Tustin, California for analysis of VOCs by United States Environmental Protection Agency (EPA)Method 8260B. Due to the limited working space within the suite and the proximity to building foundations, it may not be practical to perform over-excavation if analytical results from confirmation soil samples exceed the applicable SFRWQCB ESLs for commercial soil. The excavated area will be backfilled with a combination of CLSM slurry (to facilitate slot-cutting) and compacted crushed stone, and the slab will be restored as shown on the RH Cleaners Soil Excavation WorkPlan_20220729 6 July 29,2022 14 Geosyntec° consultants excavation plans. As indicated above, the Engineer will work with the City of Tustin for scheduling the appropriate inspections. 3.3.3 SCAQMD Monitoring Requirements To comply with specific SCAQMD requirements to mitigate the potential for fugitive dust and VOCs from the Site, specific monitoring tasks will be conducted. Based on the results of monitoring actions, mitigation measures may be implemented. Soil will be screened for VOC impacts as the material is excavated. According to the SCAQMD definition, VOC-contaminated soil is soil that registers a concentration of 50 parts per million (ppm) or greater of VOCs as measured 3 inches off the soil surface. In accordance with SCAQMD requirements, a photoionization detector(PID), calibrated to hexane according to manufacturer's specifications, will be used to monitor and record VOC emissions from excavated materials at regular intervals (at least every 15 minutes). The probe inlet of the PID will be placed at a distance of no more than 3 inches from the surface of the excavated material, and the PID measurements will be monitored while slowly moving the probe across the stockpile surface.If a PID reading above background levels is observed, the excavated materials will continue to be monitored until the maximum reading is obtained. The PID shall be paused at this location for a duration of at least two instrument response times. The PID measurement will then be recorded on designated field forms or in the field logs. Based on PID monitoring data obtained at the time of excavation, the VOC-impacted material will be segregated into stockpiles from non-VOC-impacted material. If the VOC concentration from the excavated soil is greater than 1,000 ppm, the soil will be sprayed with water or suppressant and placed in a sealed container(roll-off bin)within 15 minutes or directly loaded into a suitable plastic-lined truck, moistened with water, and covered with a tarp for immediate offsite transportation to the appropriate disposal facility. If VOC emissions are recorded above 50 ppm from the stockpiled soil,the stockpile may be wetted with water spray or an application of commercial suppressant (e.g., Rusmar® AC-645 Foam or equivalent). Exposed VOC-impacted soil surfaces will be kept moist at all times with water or an approved suppressant and will be re-covered during periods of inactivity greater than 1 hour. The commercial suppressants and sealants will be prepared and applied in accordance with manufacturers' recommendations. RH Cleaners Soil Excavation WorkPlan_20220729 7 July 29,2022 15 Geosyntec° consultants 3.3.4 Stockpile Management 3.3.4.1 Soil Segregation and Stockpiling As shown in Figure 2, the highest concentrations of PCE and TCE were encountered between 3 and 5 feet bgs during the January 2022 soil investigation.Up to four stockpiles are anticipated to be created, as described below: • Soil excavated from 0 to 3 feet bgs, which is not VOC-impacted, as defined in Section 3.3.3; • Soil excavated from 0 to 3 feet bgs, which is VOC-impacted; • Soil excavated between 3 and 5 feet bgs,which is not VOC-impacted; and • Soil excavated between 3 and 5 feet bgs,which is VOC-impacted. Stockpiled soils will be placed on plastic sheeting. If multiple plastic sheets are needed beneath the stockpile or covering the stockpile,the sheeting will be overlapped by at least 24 inches. At the end of each workday, all stockpiles will be completely covered, and the covers securely anchored. 3.3.4.2 Soil Stockpile Sampling At least one soil sample will be collected from each stockpile to evaluate off-Site disposal options. Each stockpile sample will consist of a discrete sample collected from a random location at least 2 feet into the interior portion of the stockpile using hand tools such as a hand auger or a shovel. After the sample is collected, the stockpile will be labeled to match the sample name. Stockpile samples will be analyzed for VOCs by EPA Method 8260B, total petroleum hydrocarbons (gasoline, diesel, and motor oil ranges) by EPA Method 801513, and Title 22 Metals by EPA Method 6010B. If necessary, leaching tests may be run to determine whether the soils may be treated as characteristically non-hazardous, non-Resource Conservation and Recovery Act (RCRA) hazardous (also known as California hazardous), or RCRA hazardous. Additional analyses may be required by the selected soil disposal facility. Selection of the disposal facility will be discussed with the Contractor and will be based on an evaluation of cost and the availability for the identified facilities to accept such waste at the time of disposal. RH Cleaners Soil Excavation WorkPlan_20220729 8 July 29,2022 16 Geosyntec° consultants 3.3.5 Loading and Hauling In accordance with SCAQMD Rule 1166 requirements, off-Site disposal of VOC-contaminated soil will be performed within 30 days. It is anticipated that approximately 156 tons of soil will be characterized and off-hauled to an appropriate and client-approved facility. Trucks may be loaded directly from excavation stockpiles. Trucks will be routed and the stockpile areas will be located so as to avoid interruptions to the existing facilities operations. Trucks will be lined (if requested by the waste hauler) and tarped prior to exiting the Site. All VOC-impacted soil hauled from the Site will comply with the following: • Materials will be transported to an approved treatment/disposal facility. • No excavated material may extend above the sides or rear of the truck/trailer. • Trucks/trailers carrying impacted soils will be completely tarped/covered to prevent particulate emissions into the atmosphere. • The exterior of the trucks/trailers shall be cleaned off prior to leaving the Site. 3.3.6 Excavation Backfill and Slab Restoration The Contractor will backfill excavated soil area with certified-clean CLSM and compacted crushed stone. Proper documentation must be provided and approved by the client or client representative prior to it being delivered to the Site. The Contractor will construct the replacement slab according to the excavation design plans provided in Appendix A. 3.4 Field Documentation During the excavation activities described above, a field engineer or geologist under the supervision of a California Professional Geologist or Engineer will document field observations. The field notes will contain pertinent observations about excavation dimensions, equipment operation, unusual conditions encountered during excavation, date and time of arrival, general Site conditions, and other field observations relating to the Site. Field documentation will also include photographs, written logs, information about Site meetings,health and safety training, and chain-of-custody records.

Hand tools and sampling equipment shall be decontaminated as needed by washing in decontamination basins with appropriate solutions, or, if possible, by dry decontamination. Wash solutions and PPE may require disposal at a licensed waste facility. 16. SPILL CONTAINMENT The task(s) for this project may involve the handling of drums and/or containers that contain stored chemicals, hazardous materials, and/or wastes. The drums and/or containers may have been spilled/dislodged during site activities due to compromised construction of the drum/container, transportation accidents, improper packaging practices, and improper handling of hazardous materials during on/off loading. Containers shall be inspected, and their integrity assured prior to being moved and/or handled. If the integrity of the container is in question,the container shall be over packed, or its contents transferred. Operations shall be organized and coordinated to minimize movement of such containers. Where spills, leaks, or ruptures may potentially occur, a supply of sorbents shall be located in the immediate area. Additional preventative measures include: • UN-approved 55-gallon drums, bins, and/or Baker tanks will be inspected for visible defects upon delivery to the site; Health and Safety Plan 21 29.07.2022 63 Geosyntec consultants • UN-approved 55-galon drums will also be inspected to ensure each drum includes a resealable lid with a small resealable sampling port near the top, or on the side of the drum and that the enclosure is not deformed and/or distorted; • Drums will not be completely filled to allow for possible expansion of liquid and will be set on wooden pallets to facilitate transport by forklift; • The storage area will be inspected to check for leaks weekly while the containers are being filled and immediately after a relocation to a temporary on-site storage area; and • Flat areas will be selected for temporary storage away from high-traffic work areas/zones and storm/sewer drains. In the event of an unplanned release or spill of unknown or hazardous substances,the site supervisor will designate personnel who will support the spill containment, control, and/or clean-up procedures. The team will request additional off-site emergency response assistance if necessary, based on the type of spill, volume,potential toxicity, etc. The spill area will be isolated and restricted to only authorized personnel designated to assist with the containment, control, or clean-up activity. Authorized personnel will be trained to contain and clean spills from typical materials and quantities used at the project location. Physical barriers will be set up to warn unauthorized personnel to stay clear and evacuate the affected area. The spill, leak, or incident will be assessed by the team and characterized to determine the appropriate course(s) of action(s)to consider: • Small spills (i.e., maximum volume of 55 gallons of a liquid or 100 pounds of a solid) may be remediated using absorbent materials by designated personnel; • Large spills (i.e., liquid volumes greater than 55 gallons or solid weights greater than 100 pounds) and/or spills of highly toxic materials may require assistance by off-site hazardous materials (HAZMAT)teams; • Attempts shall be made to identify and stop the source(s) of spillage immediately while donning proper PPE(based on action levels and the air monitoring program) and performing air monitoring; • The site supervisor will direct spill-response operations and stay at the spill area until it has been cleaned, inspected, and cleared for re-entry; and Health and Safety Plan 22 29.07.2022 64 Geosyntec consultants • The site supervisor will prepare a spill incident and clean-up report and will communicate findings to the Project and Branch Manager and H&S Department. 17.

Respirable silica from concrete cutting. STORAGE/TRANSPORT OF IDW: In accordance with SCAQMD requirements,a photoionization detector(PID),calibrated to hexane according to manufacturer's specifications,will be used to monitor and record VOC emissions from excavated materials at regular intervals(at least every 15 minutes).The probe inlet of the PID will be placed at a distance of no more than 3-inches from the surface of the excavated material and the PID measurements will be monitored while slowly moving the probe across the stockpile surface.If a PID reading above background levels is observed,the excavated materials will continue to be monitored until the maximum reading is obtained.The PID shall be paused at this location for duration of at least two instrument response times.The PID measurement will then be recorded on designated field forms or in the field logs. Based on PID monitoring data obtained at the time of excavation,the VOC impacted material will be segregated into stockpiles from non-VOC impacted material. If the VOC concentration from the excavated soil is greater than 1,000 ppm,the soil will be sprayed with water or suppressant and placed in a sealed container (roll-off bin)within 15 minutes or directly loaded into a suitable plastic-lined truck,moistened with water,and covered with a tarp for immediate offsite transportation to the appropriate disposal facility. If VOC emissions are recorded above 50 ppm from stockpiled soil,the stockpile may be wetted with water spray or application of commercial suppressant(e.g., Rusmar®AC-645 Foam or equivalent).Exposed VOC-impacted soil surfaces will be kept moist at all times with water or an approved suppressant,and will be re- covered during periods of inactivity greater than 1 hour.The commercial suppressants and sealants will be prepared and applied in accordance with manufacturers' Trucks/trailers carrying impacted soils will be completely tarped/covered to prevent particulate emission to atmosphere.In addition,no excavation material may extend above the sides or rear of the truck/trailer.The exterior of the trucks will be cleaned off prior to leaving the site. The area for stockpiling will be surrounded with sandbags and the stockpiles will be placed on plastic sheeting. When cutting or drilling through the concrete slab,workers will maintain a safe distance,or stand outside the building,to avoid exposure to Silica dust. CHECK ALL THAT APPLY.

They readily form vapors which can accumulate in indoor air spaces (i.e., via migration through the subsurface) and react with ozone to form sub-micron sized particles with the potential to cause adverse respiratory health effects. Free product releases (via surface or subsurface discharges or inadequate disposal) can migrate downward to significant depths and through fine-grained deposits to groundwater and can persist as wide-scale sources of vapor plumes for long periods of time. Several chlorinated hydrocarbons have been identified in soil, indoor air vapor, and groundwater at the site including perchloroethylene (PCE), trichloroethylene (TCE), and 1,2-dichloroethane (DCA). The likely routes of exposure to chlorinated solvents include inhalation, ingestion and direct contact with the skin or eye. The toxicity of chlorinated solvents varies; many affect the CNS, and some are identified as carcinogens. PCE can affect the CNS and cause irritation of the skin, eyes, and upper respiratory tract. TCE can depress the CNS, affect kidneys, liver, and lungs and can cause rapid and irregular heartbeat. Toxic effects are increased when combined with alcohol, caffeine, and other drugs. DCA can cause CNS depression and damage to the liver, kidneys, heart, and digestive system. Eye contact with DCA can cause irritation and serious injury if not removed promptly. DCA and TCE are flammable liquids; the LEL of both solvents are approximately 6% and their flash points are less than 100°F. PCE is not considered flammable. These chlorinated solvents are only slightly soluble in water. Exposure levels will be maintained below OSHA PEL or NIOSH REL as shown in the table below.

US regulations require reporting releases of this material to the environment which exceed the applicable reportable quantity or oil spills which could reach any waterway including intermittent dry creeks. The National Response Center can be reached at (800)424-8802. PROTECTIVE MEASURES Avoid contact with spilled material. Warn or evacuate occupants in surrounding and downwind areas if required due to toxicity or flammability of the material. See Section 5 for fire fighting information. See the Hazard Identification Section for Significant Hazards. See Section 4 for First Aid Advice. See Section 8 for advice on the minimum requirements for personal protective equipment. Additional protective measures may be necessary, depending on the specific circumstances and/or the expert judgment of the emergency responders. For emergency responders: Respiratory protection: half-face or full-face respirator with filter(s)for organic vapor and, when applicable, H2S, or Self Contained Breathing Apparatus (SCBA) can be used depending on the size of spill and potential level of exposure. If the exposure cannot be completely characterized or an oxygen deficient atmosphere is possible or anticipated, SCBA is recommended. Work gloves that are resistant to aromatic hydrocarbons are recommended. Note: gloves made of polyvinyl acetate (PVA)are not water- resistant and are not suitable for emergency use. Chemical goggles are recommended if splashes or contact 119 E*pnMobil Product Name: NO. 2 DIESEL FUEL Revision Date: 22 Oct 2019 Page 5 of 14 with eyes is possible. Small spills: normal antistatic work clothes are usually adequate. Large spills: full body suit of chemical resistant, antistatic material is recommended. SPILL MANAGEMENT Land Spill: Eliminate all ignition sources (no smoking, flares, sparks or flames in immediate area). Stop leak if you can do it without risk. All equipment used when handling the product must be grounded. Do not touch or walk through spilled material. Prevent entry into waterways, sewer, basements or confined areas. A vapor suppressing foam may be used to reduce vapors. Use clean non-sparking tools to collect absorbed material. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. Large Spills: Water spray may reduce vapor; but may not prevent ignition in closed spaces. Water Spill: Stop leak if you can do it without risk. Eliminate sources of ignition. Warn other shipping. If the Flash Point exceeds the Ambient Temperature by 10 degrees C or more, use containment booms and remove from the surface by skimming or with suitable absorbents when conditions permit. If the Flash Point does not exceed the Ambient Air Temperature by at least 10C, use booms as a barrier to protect shorelines and allow material to evaporate. Seek the advice of a specialist before using dispersants. Water spill and land spill recommendations are based on the most likely spill scenario for this material; however, geographic conditions, wind, temperature, (and in the case of a water spill)wave and current direction and speed may greatly influence the appropriate action to be taken. For this reason, local experts should be consulted. Note: Local regulations may prescribe or limit action to be taken. ENVIRONMENTAL PRECAUTIONS Large Spills: Dike far ahead of liquid spill for later recovery and disposal. Prevent entry into waterways, sewers, basements or confined areas. SECTION 7 HANDLING AND STORAGE HANDLING Avoid all personal contact. Do not siphon by mouth. Do not use as a cleaning solvent or other non-motor fuel uses. For use as a motor fuel only. It is dangerous and/or unlawful to put fuel into unapproved containers. Do not fill container while it is in or on a vehicle. Static electricity may ignite vapors and cause fire. Place container on ground when filling and keep nozzle in contact with container. Do not use electronic devices (including but not limited to cellular phones, computers, calculators, pagers or other electronic devices, etc.) during safety critical tasks, such as bulk fuel loading or unloading operations, or in storage areas where vapors may be present, unless the devices are certified intrinsically safe by an approved national testing agency and to the safety standards required by national and/or local laws and regulations. Prevent small spills and leakage to avoid slip hazard. Material can accumulate static charges which may cause an electrical spark(ignition source). Use proper bonding and/or ground procedures. However, bonding and grounds may not eliminate the hazard from static accumulation. Consult local applicable standards for guidance. Additional references include American Petroleum Institute 2003 (Protection Against Ignitions Arising out of Static, Lightning and Stray Currents) or National Fire Protection Agency 77 (Recommended Practice on Static Electricity)or CENELEC CLC/TR 50404 (Electrostatics-Code of practice for the avoidance of hazards due to static electricity). Static Accumulator: This material is a static accumulator. A liquid is typically considered a nonconductive, static accumulator if its conductivity is below 100 pS/m (100x10E-12 Siemens per meter)and is considered a semiconductive, static accumulator if its conductivity is below 10,000 pS/m. Whether a liquid is nonconductive or semiconductive, the precautions are the same. A number of factors, for example liquid temperature, presence of contaminants, anti-static additives and filtration can greatly influence the conductivity of a liquid. 120 E*,onMobil Product Name: NO. 2 DIESEL FUEL Revision Date: 22 Oct 2019 Page 6 of 14 STORAGE The type of container used to store the material may affect static accumulation and dissipation. Keep container closed. Handle containers with care. Open slowly in order to control possible pressure release. Store in a cool, well-ventilated area. Storage containers should be grounded and bonded. Fixed storage containers, transfer containers and associated equipment should be grounded and bonded to prevent accumulation of static charge. Keep away from incompatible materials.

Hold eyelids open to ensure adequate flushing. Seek medical attention. First Aid: Skin Remove contaminated clothing. Wash contaminated areas thoroughly with soap and water or with waterless hand cleanser. Obtain medical attention if irritation or redness develops. First Aid: Ingestion DO NOT INDUCE VOMITING. Do not give liquids. Obtain immediate medical attention. If spontaneous vomiting occurs, lean victim forward to reduce the risk of aspiration. Monitor for breathing difficulties. Small amounts of material which enter the mouth should be rinsed out until the taste is dissipated. First Aid: Inhalation Remove person to fresh air. If person is not breathing, provide artificial respiration. If necessary, provide additional oxygen once breathing is restored if trained to do so. Seek medical attention immediately. * * * Section 5 - Fire Fighting Measures General Fire Hazards See Section 9 for Flammability Properties. Vapors may be ignited rapidly when exposed to heat, spark, open flame or other source of ignition. Flowing product may be ignited by self-generated static electricity. When mixed with air and exposed to an ignition source, flammable vapors can burn in the open or explode in confined spaces. Being heavier than air, vapors may travel long distances to an ignition source and flash back. Runoff to sewer may cause fire or explosion hazard. Hazardous Combustion Products Carbon monoxide, carbon dioxide and non-combusted hydrocarbons (smoke). Contact with nitric and sulfuric acids will form nitrocresols that can decompose violently. Extinguishing Media SMALL FIRES: Any extinguisher suitable for Class B fires, dry chemical, CO2, water spray, fire fighting foam, or gaseous extinguishing agent. LARGE FIRES: Water spray, fog or fire fighting foam. Water may be ineffective for fighting the fire, but may be used to cool fire-exposed containers. Firefighting foam suitable for polar solvents is recommended for fuel with greater than 10% oxygenate concentration. Unsuitable Extinguishing Media None Page 3 of 16 Revision Date 8/30/12 132 Safety Data Sheet Material Name: Gasoline All Grades SDS No. 9950 Fire Fighting Equipment/Instructions Small fires in the incipient(beginning)stage may typically be extinguished using handheld portable fire extinguishers and other fire fighting equipment. Firefighting activities that may result in potential exposure to high heat, smoke or toxic by-products of combustion should require NIOSH/MSHA-approved pressure-demand self- contained breathing apparatus with full facepiece and full protective clothing. Isolate area around container involved in fire. Cool tanks, shells, and containers exposed to fire and excessive heat with water. For massive fires the use of unmanned hose holders or monitor nozzles may be advantageous to further minimize personnel exposure. Major fires may require withdrawal, allowing the tank to burn. Large storage tank fires typically require specially trained personnel and equipment to extinguish the fire, often including the need for properly applied fire fighting foam. * * * Section 6 - Accidental Release Measures Recovery and Neutralization Carefully contain and stop the source of the spill, if safe to do so. Materials and Methods for Clean-Up Take up with sand or other oil absorbing materials. Carefully shovel, scoop or sweep up into a waste container for reclamation or disposal. Caution, flammable vapors may accumulate in closed containers. Emergency Measures Evacuate nonessential personnel and remove or secure all ignition sources. Consider wind direction; stay upwind and uphill, if possible. Evaluate the direction of product travel, diking, sewers, etc. to confirm spill areas. Spills may infiltrate subsurface soil and groundwater; professional assistance may be necessary to determine the extent of subsurface impact. Personal Precautions and Protective Equipment Response and clean-up crews must be properly trained and must utilize proper protective equipment (see Section 8). Environmental Precautions Protect bodies of water by diking, absorbents, or absorbent boom, if possible. Do not flush down sewer or drainage systems, unless system is designed and permitted to handle such material. The use of fire fighting foam may be useful in certain situations to reduce vapors. The proper use of water spray may effectively disperse product vapors or the liquid itself, preventing contact with ignition sources or areas/equipment that require protection. Prevention of Secondary Hazards None * * * Section 7 - Handling and Storage Handling Procedures USE ONLY AS A MOTOR FUEL. DO NOT SIPHON BY MOUTH Handle as a flammable liquid. Keep away from heat, sparks, and open flame! Electrical equipment should be approved for classified area. Bond and ground containers during product transfer to reduce the possibility of static-initiated fire or explosion. Page 4 of 16 Revision Date 8/30/12 133 Safety Data Sheet Material Name: Gasoline All Grades SDS No. 9950 Special slow load procedures for"switch loading" must be followed to avoid the static ignition hazard that can exist when higher flash point material (such as fuel oil) is loaded into tanks previously containing low flash point products (such as this product)-see API Publication 2003, "Protection Against Ignitions Arising Out Of Static, Lightning and Stray Currents." Storage Procedures Keep away from flame, sparks, excessive temperatures and open flame. Use approved vented containers. Keep containers closed and clearly labeled.

Respiratory Organs Sensitization/Skin Sensitization This product is not reported to have any skin sensitization effects. Generative Cell Mutagenicity This product may cause genetic defects. Carcinogenicity A: General Product Information May cause cancer. Page 8 of 16 Revision Date 8/30/12 137 Safety Data Sheet Material Name: Gasoline All Grades SDS No. 9950 IARC has determined that gasoline and gasoline exhaust are possibly carcinogenic in humans. Inhalation exposure to completely vaporized unleaded gasoline caused kidney cancers in male rats and liver tumors in female mice. The U.S. EPA has determined that the male kidney tumors are species-specific and are irrelevant for human health risk assessment. The significance of the tumors seen in female mice is not known. Exposure to light hydrocarbons in the same boiling range as this product has been associated in animal studies with effects to the central and peripheral nervous systems, liver, and kidneys. The significance of these animal models to predict similar human response to gasoline is uncertain. This product contains benzene. Human health studies indicate that prolonged and/or repeated overexposure to benzene may cause damage to the blood-forming system (particularly bone marrow), and serious blood disorders such as aplastic anemia and leukemia. Benzene is listed as a human carcinogen by the NTP, IARC, OSHA and ACGIH.

FIRST AID MEASURES EYES: N/A SKIN: N/A INGESTION: Not required INHALATION: PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASED OF OVEREXPOSURE. RESCUE PERSONNEL SHOULD BE EQUIPPED THE SELF-CONTAINED BREATHING APPARATUS. Victims should be assisted to an uncontaminated area and inhale fresh air. Quick removal from the contaminated area is most important. If breathing has stopped administer artificial resuscitation and supplemental oxygen. Further treatment should be symptomatic and supportive. 5. FIRE-FIGHTING MEASURES These containers hold gas under pressure,with no liquid phase. If involved in a major fire,they should be sprayed with water to avoid pressure increases,otherwise pressures will rise and ultimately they may distort or burst to release the contents. The gases will not add significantly to the fire, but containers or fragments may be projected considerable distances-thereby hampering fire fighting efforts. 6. ACCIDENTAL RELEASE MEASURES In terms of weight, these containers hold very little contents, such that any accidental release by puncturing etc. will be of no practical concern. 7. HANDLING AND STORAGE Suck back of water into the container must be prevented. Do not allow backfeed into the container.

FIRE-FIGHTING MEASURES These containers hold gas under pressure,with no liquid phase. If involved in a major fire,they should be sprayed with water to avoid pressure increases,otherwise pressures will rise and ultimately they may distort or burst to release the contents. The gases will not add significantly to the fire, but containers or fragments may be projected considerable distances-thereby hampering fire fighting efforts. 6. ACCIDENTAL RELEASE MEASURES In terms of weight, these containers hold very little contents, such that any accidental release by puncturing etc. will be of no practical concern. 7. HANDLING AND STORAGE Suck back of water into the container must be prevented. Do not allow backfeed into the container. Use only properly specified equipment which is suitable for this product, its supply pressure and temperature. Use only in well-ventilated areas. Do not heat cylinder by any means to increase rate of product from the cylinder. Do not allow the temperature where cylinders are stored to exceed 130OF(540C). 8.
