Air Quality Assessment 1 INTRODUCTION This report documents the results of an Air Quality Assessment completed for the Myford II Project (Project). The purpose of this Air Quality Assessment is to evaluate the potential construction and operational emissions associated with the Project and determine the level of impact the Project would have on the environment. 1.1 Project Location The proposed Project is located at 14321 and 14351 Myford Road in the City of Tustin (City), California, just west of the City's border with the City of Irvine.The City is in central Orange County, bordered by the cities of Irvine and Santa Ana to the west;the City of Orange and unincorporated County of Orange areas to the north; and on the east by the City of Irvine and unincorporated County of Orange territory (see Figure 1: Regional Vicinity and Figure 2: Site Vicinity). The site is occupied by two existing industrial/office buildings totaling 136,098 totaling square feet and is bounded by commercial buildings to the north, west and south, and Myford Road to the east, within the Planned Community Industrial (PC IND)zoning designation. Regional access to the site is provided by State Route 261 (SR-261) freeway, located approximately 0.3 miles east of the Project site, the Interstate 5 (1- 5)freeway, located approximately 0.7 miles north of the site, and State Route 55 (SR-55)freeway located approximately 3 miles west of the site. 1.2 Project Description The proposed Myford 11 Project is comprised of one warehouse distribution building totaling approximately 148,437 square feet with office space, parking, and landscaping on approximately 7.18 net acres as shown in Figure 3: Site Plan. Access to the site would be provided via three driveways on Myford Road. Warehouse Facility The proposed Project is currently planned as a "speculative building." Therefore, the future tenant(s) or buyer(s) of the building are not currently known. The proposed Project consists of a logistics warehouse building of approximately 148,437-square feet on approximately 7.18 acres.The warehouse Project would include 143,437 square feet of warehouse space and approximately 5,000-square feet of office space, in addition to other associated facilities and improvements, such as a perimeter fencing, parking, onsite and perimeter landscaping, lighting, and exterior sidewalks. Site Access Vehicular and truck site access is provided via three driveways off southbound Myford Road ranging size from 27' to 35'. The Project driveways will only service the Project. The drive aisles located on both the north and south side of the building will be 35 feet wide. August 2022 City of Tustin Myford II Project Air Quality Assessment Parking Parking would be located along the east and west perimeters of the site. The proposed Project would provide 103 automobile parking stalls and 19 dock doors. The dock doors will be oriented to face west. Daily activities within the Project site will include maneuvering forklifts, lift equipment, and large semi- trucks through and around the site and backing into the loading docks, all of which emit warning (high pitch beep beep) sounds consistent with the Occupational Safety and Health Administration (OSHA) requirements.

Air quality in this area is determined by such natural factors as topography, meteorology, and climate, in addition to the presence of existing air pollution sources and ambient conditions.These factors along with applicable regulations are discussed below. The SCAB is part of a semi-permanent high-pressure zone in the eastern Pacific. As a result,the climate is mild and tempered by cool sea breezes. This usually mild weather pattern is occasionally interrupted by periods of extreme heat, winter storms, and Santa Ana winds. The annual average temperature throughout the 6,645-square-mile SCAB ranges from low 60 to high 80 degrees Fahrenheit with little variance. With more oceanic influence, coastal areas show less variability in annual minimum and maximum temperatures than inland areas. Contrasting the steady pattern of temperature, rainfall is seasonally and annually highly variable. Almost all annual rainfall occurs between the months of November and April.Summer rainfall is reduced to widely scattered thundershowers near the coast,with slightly heavier activity in the east and over the mountains. Although the SCAB has a semiarid climate, the air closer to the Earth's surface is typically moist because of the presence of a shallow marine layer. Except for occasional periods when dry, continental air is brought into the SCAB by offshore winds, the "ocean effect" is dominant. Periods of heavy fog are frequent and low clouds known as high fog are characteristic climatic features, especially along the coast. Annual average humidity is 70 percent at the coast and 57 percent in the eastern portions of the SCAB. Wind patterns across the SCAB are characterized by westerly or southwesterly on-shore winds during the day and easterly or northeasterly breezes at night. Wind speed is typically higher during the dry summer months than during the rainy winter. Between periods of wind, air stagnation may occur in both the morning and evening hours. Air stagnation is one of the critical determinants of air quality conditions on any given day. During winter and fall, surface high-pressure systems over the SCAB, combined with other meteorological conditions, result in very strong, downslope Santa Ana winds. These winds normally continue for a few days before predominant meteorological conditions are reestablished. The mountain ranges to the east affect the diffusion of pollutants by inhibiting the eastward transport of pollutants.Air quality in the SCAB generally ranges from fair to poor and is similar to air quality in most of coastal Southern California. The entire region experiences heavy concentrations of air pollutants during prolonged periods of stable atmospheric conditions. In addition to the characteristic wind patterns that affect the rate and orientation of horizontal pollutant transport, two distinct types of temperature inversions control the vertical depth through which air pollutants are mixed.These inversions are the marine inversion and the radiation inversion.The height of 1 South Coast Air Quality Management District,CEQA Air Quality Handbook,1993. August 2022 City of Tustin Myford II Project Air Quality Assessment the base of the inversion at any given time is called the "mixing height." The combination of winds and inversions is a critical determinant leading to highly degraded air quality for the SCAB in the summer and generally good air quality in the winter. 2.2 Air Pollutants of Concern The air pollutants emitted into the ambient air by stationary and mobile sources are regulated by state and federal laws.These regulated air pollutants are known as"criteria air pollutants" and are categorized into primary and secondary pollutants. Primary air pollutants are emitted directly from sources. Carbon monoxide (CO), reactive organic gases (ROG), nitrogen oxide (NOx), sulfur dioxide(SO2), coarse particulate matter(PM1o),fine particulate matter (PM2.5),and lead are primary air pollutants. Of these,CO, NOx, SO2, PM1o, and PM2.5 are criteria pollutants. ROG and NOx are criteria pollutant precursors and form secondary criteria pollutants through chemical and photochemical reactions in the atmosphere. For example, the criteria pollutant ozone (03) is formed by a chemical reaction between ROG and NOx in the presence of sunlight. 03 and nitrogen dioxide (NO2) are the principal secondary pollutants. Sources and health effects commonly associated with criteria pollutants are summarized in Table 1: Air Contaminants and Associated Public Health Concerns.

Notes: 1 Volatile Organic Compounds(VOCs or Reactive Organic Gases[ROG])are hydrocarbons/organic gases that are formed solely of hydrogen and carbon.There are several subsets of organic gases including ROGs and VOCs. Both ROGs and VOCs are emitted from the incomplete combustion of hydrocarbons or other carbon-based fuels.The major sources of hydrocarbons are combustion engine exhaust,oil refineries, and oil-fueled power plants;other common sources are petroleum fuels,solvents,dry cleaning solutions,and paint(via evaporation).

Toxic Air Contaminants Toxic air contaminants(TACs)are airborne substances that can cause short-term (acute)or long-term (i.e. chronic, carcinogenic or cancer causing) adverse human health effects (i.e. injury or illness).TACs include both organic and inorganic chemical substances.They may be emitted from a variety of common sources including gasoline stations,automobiles, dry cleaners, industrial operations, and painting operations.The current California list of TACs includes more than 200 compounds, including particulate emissions from diesel-fueled engines. CARB identified diesel particulate matter (DPM) as a toxic air contaminant. DPM differs from other TACs in that it is not a single substance but rather a complex mixture of hundreds of substances. Diesel exhaust is a complex mixture of particles and gases produced when an engine burns diesel fuel. DPM is a concern because it causes lung cancer; many compounds found in diesel exhaust are carcinogenic. DPM includes the particle-phase constituents in diesel exhaust.The chemical composition and particle sizes of DPM vary between different engine types (heavy-duty, light-duty), engine operating conditions (idle, accelerate, decelerate), fuel formulations (high/low sulfur fuel), and the year of the engine. Some short-term (acute) effects of diesel exhaust include eye, nose, throat, and lung irritation, and diesel exhaust can cause coughs, headaches, light-headedness, and nausea. DPM poses the greatest health risk among the TACs. Almost all diesel exhaust particle mass is 10 microns or less in diameter. Due to their extremely small size, these particles can be inhaled and eventually trapped in the bronchial and alveolar regions of the lung. Ambient Air Quality CARB monitors ambient air quality at approximately 250 air monitoring stations across the State. These stations usually measure pollutant concentrations ten feet above ground level; therefore, air quality is often referred to in terms of ground-level concentrations. Existing levels of ambient air quality, historical trends, and projections near the Project are documented by measurements made by the South Coast Air Quality Management District (SCAQMD), the air pollution regulatory agency in the SCAB that maintains air quality monitoring stations which process ambient air quality measurements. August 2022 City of Tustin Myford II Project Air Quality Assessment Pollutants of concern in the SCAB include 03, PM1o, and PM2.5. The closest air monitoring station to the Project that monitors ambient concentrations of these pollutants is the Anaheim-Pampas Lane Monitoring Station (located approximately 9.75 miles to the northwest) was used also. Local air quality data from 2018 to 2020 are provided in Table 2: Ambient Air Quality Data, which lists the monitored maximum concentrations and number of exceedances of state or federal air quality standards for each year.

Sensitive receptors that are in proximity to localized sources of toxics are of particular concern. Land uses considered sensitive receptors include residences, schools, playgrounds, childcare centers, long-term health care facilities, rehabilitation centers, convalescent centers, and retirement homes. The nearest residential community is located approximately 1,600 feet to the northwest along Tustin Ranch Road. August 2022 KimleyoHorn : „:ry 19 City of Tustin Myford II Project Air Quality Assessment 3 REGULATORY SETTING 3.1 Federal Federal Clean Air Act Air quality is federally protected by the Federal Clean Air Act(FCAA)and its amendments. Under the FCAA, the United States Environmental Protection Agency(EPA) developed the primary and secondary National Ambient Air Quality Standards (NAAQS) for the criteria air pollutants including 03, NO2, CO, SO2, PM10, PM2.5, and lead. Proposed projects in or near nonattainment areas could be subject to more stringent air- permitting requirements. The FCAA requires each state to prepare a State Implementation Plan to demonstrate how it will attain the NAAQS within the federally imposed deadlines. The EPA can withhold certain transportation funds from states that fail to comply with the planning requirements of the FCAA. If a state fails to correct these planning deficiencies within two years of Federal notification, the EPA is required to develop a Federal implementation plan for the identified nonattainment area or areas. The provisions of 40 Code of Federal Regulations Parts 51 and 93 apply in all nonattainment and maintenance areas for transportation-related criteria pollutants for which the area is designated nonattainment or has a maintenance plan. The EPA has designated enforcement of air pollution control regulations to the individual states. Applicable federal standards are summarized in Table 3: State and Federal Ambient Air Quality Standards. 3.2 State of California California Air Resources Board CARB administers the air quality policy in California.The California Ambient Air Quality Standards(CAAQS) were established in 1969 pursuant to the Mulford-Carrell Act.These standards, included with the NAAQS in Table 3, are generally more stringent and apply to more pollutants than the NAAQS. In addition to the criteria pollutants, CAAQS have been established for visibility reducing particulates, hydrogen sulfide, and sulfates. The California Clean Air Act (CCAA), which was approved in 1988, requires that each local air district prepare and maintain an Air Quality Management Plan (AQMP)to achieve compliance with CAAQS.These AQMPs also serve as the basis for the preparation of the State Implementation Plan for meeting federal clean air standards for the State of California. Like the EPA, CARB also designates areas within California as either attainment or nonattainment for each criteria pollutant based on whether the CAAQS have been achieved. Under the CCAA,areas are designated as nonattainment for a pollutant if air quality data shows that a state standard for the pollutant was violated at least once during the previous three calendar years. Exceedances that are affected by highly irregular or infrequent events such as wildfires, volcanoes, etc. are not considered violations of a state standard, and are not used as a basis for designating areas as nonattainment.The applicable State standards are summarized in Table 3.

' California standards for 03, carbon monoxide (except Lake Tahoe), sulfur dioxide (1-hour and 24-hour), nitrogen dioxide, suspended particulate matter-PMio,and visibility reducing particles are values that are not to be exceeded.The standards for sulfates,Lake Tahoe carbon monoxide,lead,hydrogen sulfide,and vinyl chloride are not to be equaled or exceeded.If the standard is for a 1-hour,8-hour or 24-hour average (i.e. all standards except for lead and the PMio annual standard), then some measurements may be excluded. Measurements are excluded that CARB determines would occur less than once per year on the average.The Lake Tahoe carbon monoxide standard is 6.0 ppm,a level one-half the national standard and two-thirds the State standard. 2 National standards shown are the"primary standards"designed to protect public health.National standards other than for 03,particulates and those based on annual averages are not to be exceeded more than once a year.The 1-hour 03 standard is attained if,during the most recent three-year period,the average number of days per year with maximum hourly concentrations above the standard is equal to or less than one.The 8-hour 03 standard is attained when the 3-year average of the 411 highest daily concentrations is 0.070 ppm or less.The 24-hour PMio standard is attained when the 3-year average of the 9911 percentile of monitored concentrations is less than 150µg/m3.The 24-hour PM2.1 standard is attained when the 3-year average of 98"percentiles is less than 35µg/m3. 3 Except for the national particulate standards,annual standards are met if the annual average falls below the standard at every site.The national annual particulate standard for PMio is met if the 3-year average falls below the standard at every site.The annual PM2.s standard is met if the 3-year average of annual averages spatially-averaged across officially designed clusters of sites falls below the standard. NAAQS are set by the EPA at levels determined to be protective of public health with an adequate margin of safety. 4 On October 1,2015,the national 8-hour 03 primary and secondary standards were lowered from 0.075 to 0.070 ppm.An area will meet the standard if the fourth-highest maximum daily 8-hour 03 concentration per year,averaged over three years,is equal to or less than 0.070 ppm.EPA will make recommendations on attainment designations by October 1,2016,and issue final designations October 1,2017. Nonattainment areas will have until 2020 to late 2037 to meet the health standard,with attainment dates varying based on the 03 level in the area. s The national 1-hour 03 standard was revoked by the EPA on June 15,2005. 6 In June 2002,CARB established new annual standards for PM2.5 and PMio. 7 The 8-hour California 03 standard was approved by the CARB on April 28,2005 and became effective on May 17,2006. 8 On June 2,2010,the EPA established a new 1-hour SO2 standard,effective August 23,2010,which is based on the 3-year average of the annual 9911 percentile of 1-hour daily maximum concentrations.The existing 0.030 ppm annual and 0.14 ppm 24-hourSO2 NAAQS however must continue to be used until one year following EPA initial designations of the new 1-hour SO2 NAAQS. 9 In December 2012, EPA strengthened the annual PM2.5 NAAQS from 15.0 to 12.0µg/m3. In December 2014,the EPA issued final area designations for the 2012 primary annual PM2.5 NAAQS.Areas designated "unclassifiable/attainment" must continue to take steps to prevent their air quality from deteriorating to unhealthy levels.The effective date of this standard is April 15,2015. 10 CARB has identified lead and vinyl chloride as'toxic air contaminants' with no threshold level of exposure below which there are no adverse health effects determined. 11 National lead standard,rolling 3-month average:final rule signed October 15,2008.Final designations effective December 31,2011.

August 2022 City of Tustin Myford II Project Air Quality Assessment 3.3 Regional South Coast Air Quality Management District The SCAQMD is the air pollution control agency for Orange County and the urban portions of Los Angeles, Riverside, and San Bernardino Counties. The agency's primary responsibility is ensuring that state and federal ambient air quality standards are attained and maintained in the SCAB. The SCAQMD is also responsible for adopting and enforcing rules and regulations concerning air pollutant sources, issuing permits for stationary sources of air pollutants, inspecting stationary sources of air pollutants, responding to citizen complaints, monitoring ambient air quality and meteorological conditions, awarding grants to reduce motor vehicle emissions, conducting public education campaigns, and many other activities. All projects are subject to SCAQMD rules and regulations in effect at the time of construction. The SCAQMD is also the lead agency in charge of developing the AQMP, with input from the Southern California Association of Governments(SCAG)and CARB.The AQMP is a comprehensive plan that includes control strategies for stationary and area sources, as well as for on-road and off-road mobile sources. SCAG has the primary responsibility for providing future growth projections and the development and implementation of transportation control measures. CARB, in coordination with federal agencies, provides the control element for mobile sources. The 2016 AQMP was adopted by the SCAQMD Governing Board on March 3, 2017.The purpose of the AQMP is to set forth a comprehensive and integrated program that would lead the SCAB into compliance with the federal 24-hour PM2.5 air quality standard, and to provide an update to the SCAQMD's commitments towards meeting the federal 8-hour 03 standards. The AQMP incorporates the latest scientific and technological information and planning assumptions, including the 2016 Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS) and updated emission inventory methodologies for various source categories. The SCAQMD has published the CEQA Air Quality Handbook(approved by the SCAQMD Governing Board in 1993 and augmented with guidance for Local Significance Thresholds [LST] in 2008). The SCAQMD guidance helps local government agencies and consultants to develop environmental documents required by California Environmental Quality Act (CEQA) and provides identification of suggested thresholds of significance for criteria pollutants for both construction and operation (see discussion of thresholds below). With the help of the CEQA Air Quality Handbook and associated guidance, local land use planners and consultants are able to analyze and document how proposed and existing projects affect air quality in order to meet the requirements of the CEQA review process. The SCAQMD periodically provides supplemental guidance and updates to the handbook on their website. The SCAG is the regional planning agency for Los Angeles, Orange, Ventura, Riverside, San Bernardino, and Imperial Counties and serves as a forum for regional issues relating to transportation, the economy, community development, and the environment. Under federal law, SCAG is designated as a Metropolitan Planning Organization and under State law as a Regional Transportation Planning Agency and a Council of Governments. The state and federal attainment status designations for the SCAB are summarized in Table 4:South Coast Air Basin Attainment Status.The SCAB is currently designated as a nonattainment area with respect to the State 03, PM1o, and PM2.5 standards, as well as the national 8-hour 03 and PM2.5 standards. The SCAB is designated as attainment or unclassified for the remaining state and federal standards.

The following is a list of SCAQMD rules that are required of construction activities associated with the Project: • Rule 402 (Nuisance) — This rule prohibits the discharge from any source whatsoever such quantities of air contaminants or other material which cause injury, detriment, nuisance, or annoyance to any considerable number of persons or to the public, or which endanger the comfort, repose, health, or safety of any such persons or the public, or which cause, or have a natural tendency to cause, injury or damage to business or property.This rule does not apply to odors emanating from agricultural operations necessary for the growing of crops or the raising of fowl or animals. • Rule 403 (Fugitive Dust) —This rule requires fugitive dust sources to implement best available control measures for all sources, and all forms of visible particulate matter are prohibited from crossing any property line.This rule is intended to reduce PM10 emissions from any transportation, handling, construction, or storage activity that has the potential to generate fugitive dust. PM10 suppression techniques are summarized below. August 2022 City of Tustin Myford II Project Air Quality Assessment a) Portions of a construction site to remain inactive longer than a period of three months will be seeded and watered until grass cover is grown or otherwise stabilized. b) All on-site roads will be paved as soon as feasible or watered periodically or chemically stabilized. c) All material transported off-site will be either sufficiently watered or securely covered to prevent excessive amounts of dust. d) The area disturbed by clearing, grading, earthmoving, or excavation operations will be minimized at all times. e) Where vehicles leave a construction site and enter adjacent public streets,the streets will be swept daily or washed down at the end of the workday to remove soil tracked onto the paved surface. • Rule 1113(Architectural Coatings)—This rule requires manufacturers,distributors, and end users of architectural and industrial maintenance coatings to reduce ROG emissions from the use of these coatings, primarily by placing limits on the ROG content of various coating categories. • Rule 2305(Warehouse Indirect Source Rule)-Rule 2305 was adopted by the SCAQMD Governing Board on May 7, 2021 to reduce NOx and particulate matter emissions associated with warehouses and mobile sources attracted to warehouses. This rule applies to all existing and proposed warehouses over 100,000 square feet located in the SCAQMD. Rule 2305 requires warehouse operators to track annual vehicle miles traveled associated with truck trips to and from the warehouse. These trip miles are used to calculate the warehouses WAIRE (Warehouse Actions and Investments to Reduce Emissions) Points Compliance Obligation. WAIRE Points are earned based on emission reduction measures and warehouse operators are required to submit an annual WAIRE Report which includes truck trip data and emission reduction measures. Reduction strategies listed in the WAIRE menu include acquire zero emission (ZE) or near zero emission (NZE) trucks; require ZE/NZE truck visits; require ZE yard trucks; install on-site ZE charging/fueling infrastructure; install onsite energy systems; and install filtration systems in residences, schools, and other buildings in the adjacent community. Warehouse operators that do not earn a sufficient number of WAIRE points to satisfy the WAIRE Points Compliance Obligation would be required to pay a mitigation fee. Funds from the mitigation fee will be used to incentivize the purchase of cleaner trucks and charging/fueling infrastructure in communities nearby. 3.4 Local City of Tustin General Plan The City of Tustin General Plan contains the following goals and policies that address air quality as part of the Conservation, Open Space, and Recreation Element: Goal 1: Reduce air pollution through proper land use,transportation and energy use planning. Policy 1.1: Cooperate with the South Coast Air Quality Management District and the Southern California Association of Governments in their effort to implement provisions of the region's Air Quality Management Plan, as amended. August 2022 KimleyoHorn 1 14 City of Tustin Myford II Project Air Quality Assessment Goal 2: Improve air quality by influencing transportation choices of mode,time of day, or whether to travel and to establish a jobs/housing balance Policy 2.1: Reduce vehicle trips through incentives, regulations and/or Transportation Demand Management (TDM) programs. Policy 2.7: Encourage employer rideshare and transit incentives programs by local businesses. Goal 3: Reduce particulate emissions to the greatest extent feasible.

Goal 4: Reduce emissions through reduced energy consumption. Policy 4.1: Promote energy conservation in all sectors of the City including residential, commercial, and industrial. Policy 4.2: Promote local recycling of wastes and the use of recycled materials. August 2022 KimleyoHorn 1 15 City of Tustin Myford II Project Air Quality Assessment 4 SIGNIFICANCE CRITERIA AND METHODOLOGY 4.1 Air Quality Thresholds Based upon the criteria derived from Appendix G of the CEQA Guidelines, a Project normally would have a significant effect on the environment if it would: • Conflict with or obstruct implementation of the applicable air quality plan. • Result in a cumulatively considerable net increase of any criteria pollutant for which the Project region is in nonattainment under an applicable state or federal ambient air quality standard. • Expose sensitive receptors to substantial pollutant concentrations. • Result in other emissions(such as those leading to odors)adversely affecting a substantial number of people. SCAQMD Thresholds The significance criteria established by SCAQMD may be relied upon to make the above determinations. According to the SCAQMD, an air quality impact is considered significant if the Project would violate any ambient air quality standard, contribute substantially to an existing or projected air quality violation, or expose sensitive receptors to substantial pollutant concentrations. The SCAQMD has established thresholds of significance for air quality during construction and operational activities of land use development projects, as shown in Table 5: South Coast Air Quality Management District Emissions Thresholds. Table 5:South Coast Air Quality Management District Emissions Thresholds Criteria Air Pollutants and Precursors Maximum Pounds Per Day Construction-Related Operational-Related Reactive Organic Gases(ROG) 75 55 Carbon Monoxide(CO) 550 550 Nitrogen Oxides(NOx) 100 55 Sulfur Oxides(SOx) 150 150 Coarse Particulates(PMlo) 150 150 Fine Particulates(PM2.5) 55 55 Source:South Coast Air Quality Management District,South Coast AQMDAir Quality Significance Thresholds,April 2019. Localized Carbon Monoxide In addition to the daily thresholds listed above, development associated with the Project would also be subject to the ambient air quality standards. These are addressed though an analysis of localized CO impacts.The significance of localized impacts depends on whether ambient CO levels near the Project are above state and federal CO standards (the more stringent California standards are 20 ppm for 1-hour and 9 ppm for 8-hour).The SCAB has been designated as attainment under the 1-hour and 8-hour standards. Localized Significance Thresholds In addition to the CO hotspot analysis, the SCAQMD developed LSTs for emissions of NO2, CO, PM1o, and PM2.5generated at new development sites (off-site mobile source emissions are not included in the LST August 2022 City of Tustin Myford II Project Air Quality Assessment analysis). LSTs represent the maximum emissions that can be generated at a project without expecting to cause or substantially contribute to an exceedance of the most stringent state or federal ambient air quality standards. LSTs are based on the ambient concentrations of that pollutant within the Project source receptor area (SRA), as demarcated by the SCAQMD, and the distance to the nearest sensitive receptor. LST analysis for construction is applicable for all projects that disturb 5 acres or less on a single day. The City of Tustin is located within SCAQMD SRA 17. LST's interpolated at 488 meters (between the 200- and 500-meter threshold) are provided in Table 6: Local Significance Thresholds for Construction/Operations for informational purposes and to demonstrate that the thresholds increase as acreages increase. However, because the nearest sensitive receptors are located 1,600 feet (488 meters) from the Project site the LST's are interpolated between the 200 meter and 500 meter thresholds.

Source:South Coast Air Quality Management District,Localized Significance Threshold Methodology,July 2008. 4.2 Methodology This air quality impact analysis considers construction and operational impacts associated with the Project. Where criteria air pollutant quantification was required, emissions were modeled using the California Emissions Estimator Model (CalEEMod). CalEEMod is a Statewide land use emissions computer model designed to quantify potential criteria pollutant emissions associated with both construction and operations from a variety of land use projects. Air quality impacts were assessed according to methodologies recommended by CARB and the SCAQMD. Construction equipment,trucks,worker vehicles, and ground-disturbing activities associated with Project construction would generate emissions of criteria air pollutants and precursors. Daily regional construction emissions are estimated by assuming construction occurs at the earliest feasible date (i.e., a conservative estimate of construction activities) and applying off-road, fugitive dust, and on-road emissions factors in CalEEMod. Project operations would result in emissions of area sources(consumer products),energy sources(natural gas usage and offsite electrify generation), and mobile sources (motor vehicles from Project generated vehicle trips). Project-generated increases in operational emissions would be predominantly associated with motor vehicle use.The Project vehicle trip generation was obtained from the Project's Transportation Design Procedures Analysis prepared by Kimley-Horn (April 2022), which includes 956 total daily vehicle trips, which include 28 daily truck trips. It should be noted that the aforementioned daily trips are currently excluding the deduction of the current estimated daily trips of the two industrial/office buildings located on the site. When deducted, the trips generated by the project results in a decrease of 110 daily trips. August 2022 City of Tustin Myford II Project Air Quality Assessment As discussed above,the SCAQMD provides significance thresholds for emissions associated with proposed Project construction and operations. The proposed Project's construction and operational emissions are compared to the daily criteria pollutant emissions significance thresholds in order to determine the significance of a Project's impact on regional air quality. The localized effects from the Project's on-site emissions were evaluated in accordance with the SCAQMD's Localized Significance Threshold (LST) Methodology, which uses on-site mass emissions rate look-up tables and Project-specific modeling. LSTs represent the maximum emissions from a project that are not expected to cause or contribute to an exceedance of the most stringent applicable federal or state ambient air quality standards and are developed based on the ambient concentrations of that pollutant for each source receptor area and distance to the nearest sensitive receptor. August 2022 City of Tustin Myford II Project Air Quality Assessment 5 POTENTIAL IMPACTS 5.1 Air Quality Analysis Threshold 5.1 Would the Project conflict with or obstruct implementation of the applicable air quality plan? As part of its enforcement responsibilities, the EPA requires each state with nonattainment areas to prepare and submit a State Implementation Plan that demonstrates the means to attain the federal standards. The State Implementation Plan must integrate federal, state, and local plan components and regulations to identify specific measures to reduce pollution in nonattainment areas, using a combination of performance standards and market-based programs. Similarly, under State law, the CCAA requires an air quality attainment plan to be prepared for areas designated as nonattainment regarding the state and federal ambient air quality standards. Air quality attainment plans outline emissions limits and control measures to achieve and maintain these standards by the earliest practical date. The Project is located within the SCAB, which is under the jurisdiction of the SCAQMD. The SCAQMD is required, pursuant to the FCAA, to reduce emissions of criteria pollutants for which the SCAB is in nonattainment. To reduce such emissions, the SCAQMD drafted the 2016 AQMP. The 2016 AQMP establishes a program of rules and regulations directed at reducing air pollutant emissions and achieving state (California) and national air quality standards.The 2016 AQMP is a regional and multi-agency effort including the SCAQMD,the CARB,the SCAG,and the EPA.The plan's pollutant control strategies are based on the latest scientific and technical information and planning assumptions, including SCAG's 2020 RTP/SCS, updated emission inventory methodologies for various source categories, and SCAG's latest growth forecasts.SCAG's latest growth forecasts were defined in consultation with local governments and with reference to local general plans.The Project is subject to the SCAQMD's AQMP. Criteria for determining consistency with the AQMP are defined by the following indicators: • Consistency Criterion No. 1:The Project will not result in an increase in the frequency or severity of existing air quality violations, or cause or contribute to new violations, or delay the timely attainment of air quality standards or the interim emissions reductions specified in the AQMP. • Consistency Criterion No. 2: The Project will not exceed the assumptions in the AQMP or increments based on the years of the Project build-out phase. According to the SCAQMD's CEQA Air Quality Handbook, the purpose of the consistency finding is to determine if a project is inconsistent with the assumptions and objectives of the regional air quality plans, and thus if it would interfere with the region's ability to comply with CAAQS and NAAQS. The violations to which Consistency Criterion No. 1 refers are CAAQS and NAAQS.As shown in Table 7 and Table 8, the Project would not exceed construction or operation emission standards. Therefore, the Project would not contribute to an existing air quality violation. Thus, the Project is consistent with the first criterion. Concerning Consistency Criterion No. 2, the AQMP contains air pollutant reduction strategies based on SCAG's latest growth forecasts, and SCAG's growth forecasts were defined in consultation with local governments and with reference to local general plans. The Project is consistent with the land use August 2022 KimleyoHorn 1 19 City of Tustin Myford II Project Air Quality Assessment designation and development density presented in the City's General Plan and therefore would not exceed the population or job growth projections used by the SCAQMD to develop the AQMP. Thus, the Project is consistent with the second criterion. Based on these criteria,the Project would not conflict with or obstruct implementation of the AQMP. Mitigation Measures: No mitigation is required Level of Significance: Less than significant impact. Threshold 5.2 Would the Project result in a cumulatively considerable net increase of any criteria pollutant for which the Project region is non-attainment under an applicable state or federal ambient air quality standard? Construction Emissions Construction associated with the Project would generate short-term emissions of criteria air pollutants. The criteria pollutants of primary concern within the Project area include 03-precursor pollutants(i.e. ROG and NOx) and PM10 and PM2.5. Construction-generated emissions are short term and of temporary duration, lasting only as long as construction activities occur, but would be considered a significant air quality impact if the volume of pollutants generated exceeds the SCAQMD's thresholds of significance. Construction results in the temporary generation of emissions resulting from site grading, road paving, motor vehicle exhaust associated with construction equipment and worker trips, and the movement of construction equipment, especially on unpaved surfaces. Emissions of airborne particulate matter are largely dependent on the amount of ground disturbance associated with site preparation activities as well as weather conditions and the appropriate application of water. Construction activities associated with the Project are estimated to be completed within 1 year. Construction-generated emissions associated the Project were calculated using the CARB-approved CalEEMod computer program, which is designed to model emissions for land use development projects, based on typical construction requirements. See Appendix A: Air Quality Modeling Data for more information regarding the construction assumptions used in this analysis. Predicted maximum daily construction-generated emissions for the Project are summarized in in Table 7: Construction-Related Emissions. Fugitive dust emissions may have a substantial,temporary impact on local air quality. In addition,fugitive dust may be a nuisance to those living and working in the Project vicinity. Uncontrolled dust from construction can become a nuisance and potential health hazard to those living and working nearby. SCAQMD Rules 402 and 403 (prohibition of nuisances,watering of inactive and perimeter areas,track out requirements, etc.), are applicable to the Project and were applied in CalEEMod to minimize fugitive dust emissions. Standard Condition AQ-1 requires the implementation of Rule 402 and 403 dust control techniques to minimize PM10 and PM2.5 concentration s.2 This standard condition would be required to z Standard Conditions are existing requirements and conditions of approval that are based on local, state, or federal regulations or laws that are frequently required independently of CEQA review.Applicable Standard Conditions are included at the end of this impact analysis. August 2022 KimleyoHorn 1 20 City of Tustin Myford II Project Air Quality Assessment ensure compliance with SCAQMD Rules and Regulations, which would be verified and enforced through the City's development review process.

Source:CaIEEMod version 2020.4.0.Refer to Appendix A for model outputs. Rule 1113 provides specifications on painting practices and regulates the ROG content of paint. As required by law, all architectural coatings for the Project structures would comply with SCAQMD Rule 1113. Standard Condition AQ-2 requires implementation of Rule 1113 which limits the VOC content of paint to 50 grams per liter or less.' Compliance with AQ-2 would be required to ensure compliance with SCAQMD Rules and Regulations, which would be verified and enforced through the City's development review process. As shown in Table 7,all criteria pollutant emissions would remain below their respective thresholds.While impacts would be considered less than significant, the Project would be subject to SCAQMD Rules 402, 403, and 1113, described in the Regulatory Framework subsection above and required by Standard Conditions AQ-1 and AQ-2.4 Operational Emissions Project-generated emissions would be primarily associated with motor vehicle use and area sources,such as the use of landscape maintenance equipment and architectural coatings. Long-term operational emissions attributable to the Project are summarized in Table 8: Operational Emissions. Note that emissions rates differ from summer to winter because different weather patterns affect pollutant mixing, dispersion, 03 formation, and other factors. Table 8 also provides the emissions associated with operations of the two existing industrial/office buildings totaling approximately 136,098 square feet. As shown in Table 8, the operational Project emissions are below the SCAQMD's thresholds, impacts would be less than significant 3 Applicable Standard Conditions are included at the end of this impact analysis. 4 Ibid.

Note:Total values are from CalEEMod and may not add up 100%due to rounding. 1. The highest values between summer and winter results were used as a worst case scenario As noted above,the Project's operational emissions would be associated with mobile sources (i.e., motor vehicle use), energy sources, and area sources. Each of these sources are described below. August 2022 City of Tustin Myford II Project Air Quality Assessment • Area Source Emissions. Area source emissions would be generated due to on-site equipment, architectural coating, and landscape maintenance equipment that were previously not present on the site. • Energy Source Emissions. Energy source emissions would be generated due to electricity and natural gas usage associated with the Project. Primary uses of electricity and natural gas by the Project would be for miscellaneous warehouse equipment, space heating and cooling, water heating,ventilation, lighting, appliances, and electronics. • Off-Road Equipment. Operational off-road emissions would be generated by off-road cargo handling equipment used during operational activities. For this project it was assumed that the warehouses would include three forklifts and one yard truck per SCAQMD datas. • Emergency Backup Generators. As the Project warehouse is speculative, it is unknown whether emergency backup generators would be used. Backup generators would only be used in the event of a power failure and would not be part of the Project's normal daily operations. Nonetheless, emissions associated with this equipment were included to be conservative. Emissions from an emergency backup generator for each warehouse building were calculated separately from CalEEMod; refer to Appendix A. However,CalEEMod default emissions rates were used. If backup generators are required, the end user would be required to obtain a permit from the SCAQMD prior to installation. Emergency backup generators must meet SCAQMD's Best Available Control Technology (BACT) requirements and comply with SCAQMD Rule 1470 (Requirements for Stationary Diesel-Fueled Internal Combustion and Other Compression Ignition Engines), which would minimize emissions. • Mobile Source Emissions. Mobile sources are emissions from motor vehicles, including tailpipe and evaporative emissions. Depending upon the pollutant being discussed, the potential air quality impact may be of either regional or local concern. For example, ROG, NOx, PM1o, and PM2.5 are all pollutants of regional concern. NOx and ROG react with sunlight to form 03, known as photochemical smog. Additionally, wind currents readily transport PM10 and PM2.5. However, CO tends to be a localized pollutant, dispersing rapidly at the source. Project-generated vehicle emissions are based on the trip generation within the Project Traffic Impact Study and incorporated into CalEEMod as recommended by the SCAQMD. Per the Project Traffic Memorandum, using the High-Cube Fulfillment Center Warehouse trip generation rate (Institute of Transportation Engineers [ITE]code 155)the Project would generate 956 daily vehicle trips (928 passenger cars and 28 trucks). Additionally, the existing industrial/office uses are currently estimated to generate 1,066(non-passenger car equivalent)daily trips.When deducted, the trips generated by the project results in a decrease of 110 daily trips. Table 8 shows the net mobile source emissions would be below SCAQMD thresholds for each of the criteria pollutants analyzed. As such,the Project would not violate any air quality standards or contribute substantially to an existing or projected air quality violation. As a result, impacts associated with operational air quality related specifically to mobile emissions would be less than significant. 5 SCAQMD,High Cube Warehouse Truck Trip Study White Paper Summary of Business Survey Results,June 2014. August 2022 KimleyoHorn 1 23 City of Tustin Myford II Project Air Quality Assessment It should be noted that SCAQMD Rule 2305 requires the Project operator to directly reduce NOx and particulate matter emissions or to otherwise facilitate emission and exposure reductions of these pollutants in nearby communities.Alternatively,warehouse operators can choose to pay a mitigation fee. Funds from the mitigation fee will be used to incentivize the purchase of cleaner trucks and charging/fueling infrastructure in communities nearby. Warehouse owners and operators are required to earn Warehouse Actions and Investments to Reduce Emissions (WAIRE) Points each year. WAIRE points are a menu-based system earned by emission reduction measures.Warehouse operators are required to submit an annual WAIRE Report which includes truck trip data and emission reduction measures.WAIRE points can be earned by completing actions from a menu that can include acquiring and using natural gas, Near-Zero Emissions and/or Zero-Emissions on- road trucks, zero-emission cargo handling equipment, solar panels or zero-emission charging and fueling infrastructure, or other options. Therefore, the Project operator would be required to implement additional emission reduction strategies. Conservatively, this analysis does not take credit for these potential reductions. Compliance with Rule 2305 would reduce emissions below what is currently analyzed. Cumulative Short-Term Emissions The SCAB is designated nonattainment for 03, PM1o, and PM2.5 for State standards and nonattainment for 03 and PM2.5 for Federal standards. Appendix D of the SCAQMD White Paper on Potential Control Strategies to Address Cumulative Impacts from Air Pollution (2003) notes that projects that result in emissions that do not exceed the project-specific SCAQMD regional thresholds of significance should result in a less than significant impact on a cumulative basis unless there is other pertinent information to the contrary.Therefore, if a project is estimated to result in emissions that do not exceed the thresholds, the project's contribution to the cumulative impact on air quality in the SCAB would not be cumulatively considerable.As shown in Table 7 above, Project construction-related emissions by themselves would not exceed the SCAQMD significance thresholds for criteria pollutants.Therefore,the proposed Project would not generate a cumulatively considerable contribution to air pollutant emissions during construction. The SCAQMD has developed strategies to reduce criteria pollutant emissions outlined in the AQMP pursuant to the FCAA mandates. The analysis assumed fugitive dust controls would be utilized during construction, including frequent water applications. SCAQMD rules, mandates, and compliance with adopted AQMP emissions control measures would also be imposed on construction projects throughout the SCAB, which would include related projects. Compliance with SCAQMD rules and regulations would further reduce the Project construction-related impacts. Therefore, Project-related construction emissions, combined with those from other projects in the area,would not substantially deteriorate local air quality. Construction emissions associated with the Project would not result in a cumulatively considerable contribution to significant cumulative air quality impacts. Cumulative Long-Term Impacts The SCAQMD has not established separate significance thresholds for cumulative operational emissions. The nature of air emissions is largely a cumulative impact. As a result, no single project is sufficient in size to, by itself,result in nonattainment of ambient air quality standards. Instead, individual project emissions contribute to existing cumulatively significant adverse air quality impacts. The SCAQMD developed the operational thresholds of significance based on the level above which individual project emissions would result in a cumulatively considerable contribution to the SCAB's existing air quality conditions.Therefore, August 2022 KimleyoHorn 1 24 City of Tustin Myford II Project Air Quality Assessment a project that exceeds the SCAQMD operational thresholds would also be a cumulatively considerable contribution to a significant cumulative impact. As shown in Table 8, the Project operational emissions would not exceed the SCAQMD thresholds.Therefore, impacts would be less than significant. Standard Conditions and Requirements: Standard Conditions are existing requirements and conditions of approval that are based on local, state, or federal regulations or laws that are frequently required independently of CEQA review. Typical standard conditions and requirements include compliance with the provisions of the Building Code, SCAQMD Rules, etc. The City may impose additional conditions during the approval process, as appropriate. Because Standard Conditions are neither Project specific nor a result of development of the Project,they are not considered to be either PDFs or Mitigation Measures. SC AQ-1 Prior to the issuance of grading permits,the City Engineer shall confirm that the Grading Plan, Building Plans and Specifications require all construction contractors to comply with South Coast Air Quality Management District's (SCAQMD's) Rules 402 and 403 to minimize construction emissions of dust and particulates.The measures include, but are not limited to, the following: • Portions of a construction site to remain inactive longer than a period of three months will be seeded and watered until grass cover is grown or otherwise stabilized. • All on-site roads will be paved as soon as feasible or watered periodically or chemically stabilized. • All material transported off site will be either sufficiently watered or securely covered to prevent excessive amounts of dust. • The area disturbed by clearing, grading, earthmoving, or excavation operations will be minimized at all times. • Where vehicles leave a construction site and enter adjacent public streets, the streets will be swept daily or washed down at the end of the work day to remove soil tracked onto the paved surface. SC AQ-2 The applicant shall require by contract specifications that the interior and exterior architectural coatings (paint and primer including parking lot paint) products used would comply with SCAQMD Rule 1113 which requires building envelope coatings to have a volatile organic compound rating of 50 grams per liter or less.

Mitigation Measures: No mitigation is required Level of Significance: Less than significant impact. Threshold 5.3 Would the Project expose sensitive receptors to substantial pollutant concentrations? Localized Construction Significance Analysis The nearest sensitive receptor is a residential community located 1,600 feet (488 meters) northwest of the Project along Tustin Ranch Road.To identify impacts to sensitive receptors,the SCAQMD recommends addressing LSTs for construction. LSTs were developed in response to SCAQMD Governing Boards' Environmental Justice Enhancement Initiative(I-4).The SCAQMD provided the Final Localized Significance Threshold Methodology(dated June 2003 [revised 2008])for guidance.The LST methodology assists lead agencies in analyzing localized impacts associated with Project-specific emissions. August 2022 KimleyoHorn 1 26 City of Tustin Myford II Project Air Quality Assessment Since CalEEMod calculates construction emissions based on the number of equipment hours and the maximum daily soil disturbance activity possible for each piece of equipment,Table 9: Equipment-Specific Grading Rates, is used to determine the maximum daily disturbed acreage for comparison to LSTs. The appropriate SRA for the localized significance thresholds is the Central Orange County (SRA 17) since this area includes the Project. LSTs apply to CO, NO2, PM1o, and PM2.5.The SCAQMD produced look-up tables for projects that disturb areas less than or equal to 5 acres in size. Project construction is anticipated to disturb a maximum of 2.5 acres in a single day. As the LST guidance provides thresholds for projects disturbing 1-, 2-, and 5-acres in size and the thresholds increase with size of the site, the LSTs for a 2.5- acre threshold were interpolated and utilized for this analysis. Table 9: Equipment-Specific Grading Rates Construction Equipment Equipment Acres Graded Operating Hours Acres Graded Phase Type Quantity per 8-Hour Day per Day per Day Tractors 3 0.5 8 1.5 Grading Graders 1 0.5 8 0.5 Dozers 1 0.5 8 0.5 Total Acres Graded per Day 2.5 Source:CalEEMod version 2020.4.0.Refer to Appendix A for model outputs. The SCAQMD's methodology states that "off-site mobile emissions from the Project should not be included in the emissions compared to LSTs." Therefore, only emissions included in the CalEEMod "on- site" emissions outputs were considered.The nearest sensitive receptors are the single-family residences located 1,600 feet (488 meters) northwest of the Project. LST thresholds are provided for distances to sensitive receptors of 25, 50, 100, 200, and 500 meters. Therefore, LSTs for receptors located at 488 meters were interpolated and utilized in this analysis. Table 10: Localized Significance of Construction Emissions,presents the results of localized emissions during each construction phase.Table 10 shows that emissions of these pollutants on the peak day of construction would not result in significant concentrations of pollutants at nearby sensitive receptors.Significant impacts would not occur concerning LSTs during construction.

August 2022 City of Tustin Myford II Project Air Quality Assessment Localized Operational Significance Analysis According to the SCAQMD LST methodology, LSTs would apply to the operational phase of a project only if it includes stationary sources or attracts mobile sources that may spend long periods queuing and idling at the site (e.g. warehouse or transfer facilities). Since the Project is a warehouse, the operational phase LST protocol is conservatively applied to both the area source and all the mobile source emissions. LSTs thresholds for receptors were interpolated for 488 meters because the closest receptors are 488 meters away. Although the warehouse is approximately 7.2 acres, the 5-acre LST threshold was also conservatively for the Project, as the LSTs increase with the size of the site. The LST analysis only includes on-site sources. However, the CalEEMod model outputs do not separate on-and off-site emissions for mobile sources. For a worst-case scenario assessment,the emissions shown in Table 11: Localized Significance of Operational Emissions, conservatively include all on-site Project- related stationary sources and 100 percent of the Project-related new mobile sources, since a portion of mobile sources could include trucks idling on-site. Table 11 shows that the maximum daily emissions of these pollutants during operations would not result in significant concentrations of pollutants at nearby sensitive receptors. Therefore, significant impacts would not occur concerning LSTs during operational activities.

Criteria Pollutant Health Impacts On December 24, 2018, the California Supreme Court issued an opinion identifying the need to provide sufficient information connecting a project's air emissions to health impacts or explain why such information could not be ascertained (Sierra Club v. County of Fresno [Friant Ranch, L.P.] [2018] Cal.51n Case No. S219783). The Friant Ranch project was a 942-acre Specific Plan that involved a commercial master planned community of approximately 2,500 dwelling units and extensive commercial supporting development. The anticipated air quality impacts resulting from this development included significant and unavoidable emissions of multiple criteria pollutants (including significant emissions of both primary 03 precursors [NOx and ROGs]) at levels that exceeded the daily thresholds of significance. As noted above and shown in Table 8,the Project's operational emissions are below SCAQMD's significance thresholds, resulting in a less than significant impact. The SCAQMD has set its CEQA significance thresholds based on the FCAA,which defines a major stationary source (in extreme ozone nonattainment areas such as the South Coast Air Basin) as emitting 10 tons per year. The thresholds correlate with the trigger levels for the federal New Source Review (NSR) Program August 2022 City of Tustin Myford II Project Air Quality Assessment and SCAQMD Rule 1303 for new or modified sources. The NSR Program6 was created by the FCAA to ensure that stationary sources of air pollution are constructed or modified in a manner that is consistent with attainment of health-based federal ambient air quality standards. The federal ambient air quality standards establish the levels of air quality necessary, with an adequate margin of safety, to protect the public health.Therefore, projects that do not exceed the SCAQMD's LSTs and mass emissions thresholds would not violate any air quality standards or contribute substantially to an existing or projected air quality violation and no criteria pollutant health impacts. NOx and ROG are precursor emissions that form ozone in the atmosphere in the presence of sunlight where the pollutants undergo complex chemical reactions. It takes time and the influence of meteorological conditions for these reactions to occur, so ozone may be formed at a distance downwind from the sources. Breathing ground-level ozone can result health effects that include: reduced lung function, inflammation of airways, throat irritation, pain, burning, or discomfort in the chest when taking a deep breath, chest tightness, wheezing, or shortness of breath. In addition to these effects, evidence from observational studies strongly indicates that higher daily ozone concentrations are associated with increased asthma attacks, increased hospital admissions, increased daily mortality, and other markers of morbidity. The consistency and coherence of the evidence for effects upon asthmatics suggests that ozone can make asthma symptoms worse and can increase sensitivity to asthma triggers. According the SCAQMD's 2016 AQMP,ozone, NOx, and ROG have been decreasing in the Basin since 1975 and are projected to continue to decrease in the future. Although vehicle miles traveled in the Basin continue to increase, NOx and ROG levels are decreasing because of the mandated controls on motor vehicles and the replacement of older polluting vehicles with lower-emitting vehicles. NOx emissions from electric utilities have also decreased due to the use of cleaner fuels and renewable energy. The 2016 AQMP demonstrates how the SCAQMD's control strategy to meet the 8-hour ozone standard in 2023 would lead to sufficient NOx emission reductions to attain the 1-hour ozone standard by 2022. In addition, since NOx emissions also lead to the formation of PM2.5, the NOx reductions needed to meet the ozone standards will likewise lead to improvement of PM2.5 levels and attainment of PM2.5 standards. The SCAQMD's air quality modeling demonstrates that NOx reductions prove to be much more effective in reducing ozone levels and will also lead to significant improvement in PM2.5 concentrations. NOx- emitting stationary sources regulated by the SCAQMD include Regional Clean Air Incentives Market (RECLAIM) facilities (e.g., refineries, power plants, etc.), natural gas combustion equipment (e.g., boilers, heaters, engines, burners, flares) and other combustion sources that burn wood or propane. The 2016 AQMP identifies robust NOx reductions from new regulations on RECLAIM facilities, non-refinery flares, commercial cooking, and residential and commercial appliances. Such combustion sources are already heavily regulated with the lowest NOx emissions levels achievable but there are opportunities to require and accelerate replacement with cleaner zero-emission alternatives, such as residential and commercial furnaces, pool heaters, and backup power equipment. The AQMD plans to achieve such replacements through a combination of regulations and incentives. Technology-forcing regulations can drive development and commercialization of clean technologies, with future year requirements for new or existing equipment. Incentives can then accelerate deployment and enhance public acceptability of new technologies. The 2016 AQMP also emphasizes that beginning in 2012,continued implementation of previously adopted regulations will lead to NOx emission reductions of 68 percent by 2023 and 80 percent by 2031. With the 6 Code of Federal Regulation(CFR) [i.e., PSD(40 CFR 52.21,40 CFR 51.166,40 CFR 51.165(b)), Non-attainment NSR(40 CFR 52.24,40 CFR 51.165,40 CFR part 51,Appendix S) August 2022 City of Tustin Myford II Project Air Quality Assessment addition of 2016 AQMP proposed regulatory measures, a 30 percent reduction of NOx from stationary sources is expected in the 15-year period between 2008 and 2023. This is in addition to significant NOx reductions from stationary sources achieved in the decades prior to 2008. As previously discussed, localized effects of on-site Project emissions on nearby receptors were found to be less than significant (refer to Table 10 and Table 11).The LSTs represent the maximum emissions from a project that are not expected to cause or contribute to an exceedance of the most stringent applicable state or federal ambient air quality standard. The LSTs were developed by the SCAQMD based on the ambient concentrations of that pollutant for each SRA and distance to the nearest sensitive receptor.The ambient air quality standards establish the levels of air quality necessary, with an adequate margin of safety, to protect public health, including protecting the health of sensitive populations. Information on health impacts related to exposure to ozone and particulate matter emissions published by the U.S. EPA and CARB have been summarized above and discussed in the Regulatory Framework section. As shown above, Project-related emissions would not exceed the regional thresholds or the LSTs, and therefore would not exceed the ambient air quality standards or cause an increase in the frequency or severity of existing violations of air quality standards.Therefore,sensitive receptors would not be exposed to criteria pollutant levels in excess of the health-based ambient air quality standards. Carbon Monoxide Hotspots An analysis of CO "hot spots" is needed to determine whether the change in the level of service of an intersection resulting from the Project would have the potential to result in exceedances of the CAAQS or NAAQS. It has long been recognized that CO exceedances are caused by vehicular emissions, primarily when vehicles are idling at intersections.Vehicle emissions standards have become increasingly stringent in the last 20 years. Currently, the CO standard in California is a maximum of 3.4 grams per mile for passenger cars(requirements for certain vehicles are more stringent).With the turnover of older vehicles, introduction of cleaner fuels, and implementation of control technology on industrial facilities, CO concentrations have steadily declined. Accordingly, with the steadily decreasing CO emissions from vehicles, even very busy intersections do not result in exceedances of the CO standard. The South Coast Air Basin (SCAB)was re-designated as attainment in 2007 and is no longer addressed in the SCAQMD's AQMP.The 2003 AQMP is the most recent version that addresses CO concentrations.As part of the SCAQMD CO Hotspot Analysis, the Wilshire Boulevard/Veteran Avenue intersection, one of the most congested intersections in Southern California with an average daily traffic (ADT) volume of approximately 100,000 vehicles per day, was modeled for CO concentrations. This modeling effort identified a CO concentration high of 4.6 ppm, which is well below the 35-ppm Federal standard. The Project considered herein would not produce the volume of traffic required to generate a CO hot spot in the context of SCAQMD's CO Hotspot Analysis. As the CO hotspots were not experienced at the Wilshire Boulevard/Veteran Avenue intersection even as it accommodates 100,000 vehicles daily, it can be reasonably inferred that CO hotspots would not be experienced at any vicinity intersections resulting from 956 additional daily vehicle trips (-6 net a.m. peak hour and 52 net p.m. peak hour trips)attributable to the Project.Therefore, impacts would be less than significant. Construction-Related Diesel Particulate Matter Construction would result in the generation of DPM emissions from the use of off-road diesel equipment required. The amount to which the receptors are exposed (a function of concentration and duration of exposure) is the primary factor used to determine health risk (i.e. potential exposure to TAC emission August 2022 KimleyoHorn 1 30 City of Tustin Myford II Project Air Quality Assessment levels that exceed applicable standards). Health-related risks associated with diesel-exhaust emissions are primarily linked to long-term exposure and the associated risk of contracting cancer. The use of diesel-powered construction equipment would be temporary and episodic. The duration of exposure would be short and exhaust from construction equipment dissipates rapidly. Current models and methodologies for conducting health risk assessments are associated with longer-term exposure periods of 9, 30, and 70 years, which do not correlate well with the temporary and highly variable nature of construction activities. The closest sensitive receptors are located approximately 1,600 feet from the property boundary and major Project construction areas. California Office of Environmental Health Hazard Assessment has not identified short-term health effects from DPM. Construction is temporary and would be transient throughout the site(i.e. move from location to location) and would not generate emissions in a fixed location for extended periods of time. Construction would be subject to and would comply with California regulations limiting the idling of heavy- duty construction equipment to no more than 5 minutes to further reduce nearby sensitive receptors' exposure to temporary and variable DPM emissions. For these reasons, DPM generated by construction activities, in and of itself, would not be expected to expose sensitive receptors to substantial amounts of air toxics and the Project would have a less than significant impact. Mitigation Measures: No mitigation is required. Level of Significance: Less than significant impact. Threshold 5.4 Would the Project result in other emissions (such as those leading to odors) adversely affecting a substantial number of people? The SCAQMD CEQA Air Quality Handbook identifies certain land uses as sources of odors.These land uses include agriculture (farming and livestock), wastewater treatment plants, food processing plants, chemical plants, composting facilities, refineries, landfills, dairies, and fiberglass molding. The Project would not include any of the land uses that have been identified by the SCAQMD as odor sources. During construction-related activities, some odors (not substantial pollutant concentrations)that may be detected are those typical of construction vehicles (e.g. diesel exhaust from grading and construction equipment). These odors are a temporary short-term impact that is typical of construction projects and would disperse rapidly. The Project would not include any of the land uses that have been identified by the SCAQMD as odor sources.Therefore, the Project would not create objectionable odors. Mitigation Measures: No mitigation is required. Level of Significance: No impact. August 2022 KimleyoHorn 1 31 City of Tustin Myford II Project Air Quality Assessment 6 REFERENCES 1.
