Executive Summary
On behalf of First Industrial Realty Trust, Inc., First Industrial, L.P., First Industrial Acquisitions II, LLC and their affiliates and assigns (Client), Roux Associates, Inc. (Roux) has prepared this limited Human Health Risk Assessment (HHRA) for the property located at 2042 South Grove Avenue, Ontario, California (the Subject Property). The objective of the limited HHRA was to provide a conservative evaluation of the potential risk to indoor commercial/industrial workers from exposure to chemicals detected in the soil vapor at the Subject Property in April 2022. The limited HHRA determined that carcinogenic risk and non-carcinogenic hazard to human receptors for current and future commercial/industrial indoor air scenarios at the Subject Property are within acceptable ranges.

The limited HHRA calculated the estimated risks associated with the presence of these chemicals of potential concern (COPCs) where exposure pathways are considered potentially complete pursuant to the Department of Toxic Substance Control (DTSC) Preliminary Endangerment Assessment Guidance Manual (PEA Guidance; DTSC, 2015).

The risk characterization process integrates the results of the data evaluation, exposure assessment, and toxicity assessment to provide a quantitative estimation of cumulative non-carcinogenic and carcinogenic risks for indoor commercial/industrial exposure to indoor air at the Subject Property as summarized in the table below.

Introduction
On behalf of First Industrial Realty Trust, Inc., First Industrial, L.P., First Industrial Acquisitions II, LLC and their affiliates and assigns (Client), Roux Associates, Inc. (Roux) has prepared this limited Human Health Risk Assessment (HHRA) for the property located at 2042 South Grove Avenue, Ontario, California (the Subject Property). This limited HHRA was conducted to evaluate if chemicals of potential concern (COPCs) in soil vapor, collected by Roux in April 2022, pose an unacceptable level of risk to current and future indoor commercial/industrial worker receptors. To prepare the limited HHRA, Roux used the Department of Toxic Substance Control (DTSC) Preliminary Endangerment Assessment Guidance Manual (DTSC, 2015) as guidance. The HHRA consists of four components:
• Evaluation of Exposure Pathways: Exposure to chemicals may occur via inhalation of chemicals of potential concern (COPCs) present in soil vapor at the Subject Property. • Evaluation of Exposure to COPCs and Exposure Point Concentrations: Identifies contaminants found in soil vapor at the Subject Property and determines appropriate exposure point concentrations (EPCs) for COPCs.
• Evaluation of Chemical Toxicity: Assesses the potential adverse effects of the COPCs and compiles non-carcinogenic and carcinogenic toxicity values for use in numerical risk estimates. • Risk Characterization: Integrates the results of the hazard assessment to provide a quantitative estimation of non-carcinogenic and carcinogenic risks.

Default exposure parameters and toxicity criteria from the DTSC and United States Environmental Protection Agency (USEPA) were utilized to represent a Reasonable Maximum Exposure (RME) scenario. An RME scenario is the highest exposure that is reasonably expected to occur at a Subject Property. The limited HHRA evaluates current and future commercial/industrial worker exposure to indoor air at the Subject Property.

2. Background
The Subject Property consists of a 4.2-acre parcel located in the City of Ontario, San Bernardino County, California. From a review of available resources in the Phase I ESA concurrently completed by Roux, the Subject Property was undeveloped prior to 1933. By 1946, the Subject Property had been cultivated for agricultural purposes as an orchard. The Subject Property remained agricultural until 1966. The Subject Property was then operated as a lumberyard in 1985. The South Coast Air Quality Management District (SCAQMD) issued a permit to operate (ID 9007543) for a gasoline storage and dispensing facility for the former tenant, Grove Lumber & Building Supplies, on October 6, 1981. By 1985, the Subject Property was developed with two buildings, the present-day main building and another building to the south, and associated asphalt-parking areas. The Subject Property had two 1,000-gallon underground storage tanks (USTs) (gasoline and diesel) until their removal in August 1990. Results of confirmation soil sampling following removal of the USTs revealed no detectable concentrations of total petroleum hydrocarbons (TPH), and the San Bernardino County Fire Department (SBCFD) subsequently issued a No Further Action (NFA) letter in 1991. The City of Ontario issued a building permit for the installation of a 4,500 square foot storage area in May 1999. By 2002, the previous southern building had been demolished and replaced with the present-day secondary building, likely associated with the storage area building permit issued in 1999. It is noted the western and southern portion of the Subject Property appeared unpaved by 2002, consistent with the present-day storage area for excavated material generated off-site. HHS Construction has occupied the Subject Property since June 2009. Since 2012, the exterior western lot has been used to store vehicles and other material.

Based on the preliminary findings of the subject Phase I ESA, Roux performed a concurrent Phase II subsurface investigation at the Subject Property. The Phase II was conducted to assess the following:
• Staged material originating off-site;
• Historical agricultural use;
• Former gasoline and diesel underground storage tanks (USTs); and • Potential for vapor intrusion.

Roux’s Phase II Subsurface Investigation Report (Phase II Report) concluded the following:
• In soil (from the ground surface to 10 feet below ground surface (bgs)), volatile organic compounds (VOCs), metals, polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs) and asbestos are not considered to be COPCs at the locations sampled across the Subject Property. • Limited detections of TPH in the diesel and motor oil ranges was identified in shallow soil in the area of below grade fill soil located in the southeast portion of the staging area. Roux understands that the fill soil in the staging area will be excavated and disposed of off-site in accordance with applicable regulations during future Subject Property redevelopment activities. • In soil vapor, although several VOCs were detected above laboratory reporting limits, they were all below applicable screening levels, with the exception of tetrachloroethylene (PCE) in samples SV7-5 and SV-9-5. PCE concentrations in these two samples exceeded the commercial/industrial DTSC Air Screening Level (SL) with a conservative 0.03 attenuation factor applied but did not exceed the USEPA Regional Screening Level (RSL).

3. Exposure Pathways and Media of Concern
Exposure pathways describe the course a chemical or physical agent takes from the source to the receptor (USEPA, 1989). Four components must be present for an exposure pathway to be complete:
• A primary source and mechanism of chemical release;
• A secondary source or transport medium (or media);
• A point of potential human contact with the contaminated medium (i.e., an exposure point); and • An exposure route (e.g., ingestion, dermal contact, or inhalation).

The current and future intended use of the Subject Property is for industrial/commercial purposes, and this limited HHRA was completed to evaluate the current and future indoor commercial/industrial worker scenario. Use of the Subject Property for residential purposes was not quantitatively evaluated because there is no current or proposed residential use. However, residential use of the Subject Property is not prohibited by a Land Use Covenant (LUC). Future industrial/commercial receptor indoor air exposure is considered protective of current exposure because the maximum concentration or a 95% UCL of the mean concentration of COPCs in environmental soil vapor was assumed for the exposure scenario, regardless of sample location. As discussed below, points of potential future contact with COPCs are limited to indoor air.

3.1 Soil Pathway
Per the Phase II Report (Roux, 2022b), arsenic was detected in concentrations above screening values.

However, the maximum detected arsenic concentration (5.30 mg/kg at B-5-3) was below the Southern California background arsenic concentration of 12 mg/kg (DTSC, 2020a). It is noted that limited detections of TPH were found in shallow soil at the area of below grade fill soil located within the staging area, which will reportedly be removed from the Subject Property. All other COPCs were detected at concentrations below screening values. As such, a quantitative evaluation of exposures to COPCs in soil was not completed as a part of this limited HHRA.

3.2 Groundwater/Surface Water Pathway
Per the Phase II Report (Roux, 2022b), depth to groundwater in the vicinity of the Subject Property is encountered at approximately 270 to 295 feet bgs. Roux did not collect groundwater data as part of the Phase I ESA or the Phase II Subsurface Investigation. Groundwater at the Subject Property is deeper than the maximum anticipated excavation depth during a construction worker scenario (down to 15 feet below surface). Consumption or ingestion of groundwater at the Subject Property is not prohibited; however, no groundwater wells are present on the Subject Property and current/future buildings are/will be connected to the municipal water source. As such, the groundwater pathway is not considered a complete exposure pathway and is not quantitatively evaluated as part of this limited HHRA.

3.3 Air Pathway
VOCs have been detected at the Subject Property in soil vapor samples that were collected 5 to 20 feet bgs. Therefore, vapor intrusion into indoor air is considered a potentially complete exposure pathway and was quantitatively evaluated in this HHRA.

3.4 Exposure Pathway Analysis
The current and future intended use of the Subject Property is for commercial/industrial space. Potential future receptors could include outdoor workers, construction workers, trespassers, and residents (as there is no LUC prohibiting residential use). However, based on the aforementioned information discussed in previous sections, this HHRA was limited to looking at the future indoor commercial/industrial receptor. Therefore, the conceptual site model (CSM) presented below illustrates potentially complete exposure pathways at the Subject Property evaluated in this limited HHRA:

4. Exposure Concentrations and Chemicals

4.1 Exposure Concentrations and Chemicals
Soil vapor sampling data utilized in the limited HHRA included samples collected by Roux in April 2022.

Exposure point concentrations (EPCs) for each media were equal to the following:
• Soil vapor: All compounds detected in soil vapor (VOCs) from the Roux April 2022 sampling event (Roux, 2022) were evaluated as COPCs:1,3,5-trimethylbenzene, 2-butanone, acetone, chloroethane, chloromethane, ethylbenzene, isopropanol, m,p-xylene, o-xylene, tetrachloroethene (PCE), toluene, and trichlorofluoromethane. For COPCs that were detected in ten or more samples, a 95% upper confidence limit (UCL) of the mean for samples up to 15 feet bgs was selected as the EPC for soil vapor. For the three contaminants detected in ten or more samples, no concentration measurements were statistical outliers (i.e., there are no hot spots). Therefore, the use of maximums and 95% UCLs is health protective. For COPCs that were detected in fewer than ten samples, the maximum detected concentration for samples up to 15 feet bgs was selected as the EPC for soil vapor. Roux April 2022 soil vapor samples were collected at 5 feet bgs, 10 feet bgs, 15 feet bgs, and 20 feet bgs. Soil vapor samples collected at 20 feet bgs (one sample) were excluded from this HHRA, consistent with guidance in Section 2A.3 of the Draft DTSC Supplemental Guidance (DTSC, 2020b).

Potential indoor air concentrations were calculated from soil vapor concentrations described above using methodology described in DTSC’s Preliminary Endangerment Assessment Guidance Manual (PEA Guidance; DTSC, 2015) and DTSC’s Vapor Intrusion Guidance (DTSC, 2011):

Cindoor = α x Csoil vapor
Where:

Cindoor= Indoor air concentration in µg/m3
α= Attenuation factor (assumed to be equal to 0.03 consistent with assumptions for future commercial/industrial scenarios using HERO and USEPA media-specific assumptions, respectively per DTSC, 2015, DTSC, 2020b, and DTSC, 2011).

Csoil vapor=Soil vapor air concentration in µg/m3

4.2 Quantification of Exposure
This HHRA assumed default exposure factors in EPA RSL User’s Guide for carcinogenic risk assessment of indoor worker exposure to air (USEPA, 2022b) and DTSC Note 1 (DTSC, 2019c). These exposure factors assume that the commercial/industrial worker is on-site 8 hours/day for 250 days/year for 25 years. For the cancer risk calculation, the lifetime averaging time is 70 years. If any of these default exposure assumptions is found to be invalid for this Subject Property, the HHRA may need to be revised. More details on calculation of risk and hazard from EPCs and the exposure factors presented here are described in Sections 6.1 and

6.2. 1835

5. Toxicity Values
The toxicity assessment describes the quantitative relationship between the extent of exposure to a contaminant and the increased likelihood and/or severity of adverse effects. This quantitative relationship generally takes the form of toxicity values that are identified for use in risk evaluations. Toxicity values are used to quantify the chance of observing cancer or non-cancer effects in exposed receptors. Toxicity values may be based on epidemiological studies or animal studies.

5.1 Toxicity Information for Non-Carcinogenic Effects
In assessing the potential for non-cancer health effects, USEPA assumes there is a toxicological threshold below which no adverse health effects are observable (USEPA, 1993). These toxicological thresholds are represented by reference concentrations (RfCs) for inhalation exposures. The RfCs are estimates (with uncertainty spanning, in some cases, an order of magnitude) of daily exposures to the human population (including sensitive subgroups) that are likely to be without an appreciable risk of deleterious effects during a lifetime. USEPA derives RfCs using a standardized approach, considering available information from human and animal studies, which establish the levels below which toxicological effects are not observed and the uncertainties inherent in the available information (USEPA, 1993).

5.2 Toxicity Information for Carcinogenic Effects
USEPA uses a two-part evaluation in assessing potentially carcinogenic substances. In the first part, a chemical is assigned a weight-of-evidence classification, which reflects USEPA’s assessment of the 1836
3661.0019L000 HHRA | ROUX | 8
likelihood that the chemical is a human carcinogen. For chemicals that are classified as possible, probable, or known human carcinogens, USEPA calculates an inhalation unit risk (IUR) for inhalation exposures when sufficient information is available to support the calculation. USEPA guidance indicates that a linear, nothreshold dose-response model is appropriate for carcinogenic risk assessment (USEPA, 2005). An extremely low level of exposure to a carcinogen may result in chromosomal or enzyme changes leading to cancer. Therefore, USEPA does not generally estimate thresholds for carcinogens. IURs are used to estimate the probability of a cancer effect occurring in a receptor exposed over their lifetime. 1837

6. Risk Characterization Summary
The risk characterization process integrates the results of the data evaluation, exposure assessment, and toxicity assessment to provide a quantitative estimation of cumulative non-carcinogenic and carcinogenic risks for an indoor industrial/commercial worker’s exposure to indoor air as summarized in the table below:
• Indoor Commercial/Industrial Worker: The cancer risk estimate for an indoor commercial/industrial scenario is within the risk management target cancer threshold range of 1E06 to 1E-04. The non-cancer hazard estimate is below the non-cancer hazard target threshold of 1.

6.1 Cancer Risks
For carcinogens, risk is expressed as the probability that an individual will develop cancer over a lifetime because of exposure to the carcinogen and is expressed as incremental lifetime cancer risk (ILCR).

Carcinogenic risk for each compound is calculated according to the below equation, which is a modified version of the EPA RSL User’s Guide carcinogenic screening level derivation equation indoor worker exposure to air (USEPA, 2022b):

𝐼𝐼𝐼𝐼𝐼𝐼𝐼𝐼 = 𝐸𝐸𝐸𝐸 × 𝐼𝐼𝐼𝐼𝐼𝐼 × 𝐸𝐸𝐸𝐸𝑖𝑖𝑖𝑖𝑖𝑖 × 𝐸𝐸𝐸𝐸𝑖𝑖𝑖𝑖𝑖𝑖 × 𝐸𝐸𝐸𝐸𝑖𝑖𝑖𝑖𝑖𝑖 × 1 × 2
Where:

ILCR = incremental lifetime cancer risk (unitless)
EPC = indoor air concentration (µg/m3)
IUR = inhalation unit risk (µg/m3)-1
EFind = exposure frequency (days/year)
EDind = exposure duration (years)
ETind = exposure time (hours)
LT = lifetime averaging time
C1 = 365 days/year
C2 = 24 hours/day
This HHRA assumed default exposure factors in EPA RSL User’s Guide for carcinogenic risk assessment of indoor worker exposure to air (USEPA, 2022b) and DTSC Note 1 (DTSC, 2019c). 1838
3661.0019L000 HHRA | ROUX | 10
The combined risk from exposure to multiple constituents is evaluated by adding the risks from individual constituents, and multiple exposure pathways (as applicable) known as cumulative risk. The National Oil and Hazardous Substances Pollution Contingency Plan (NCP; 40 CFR 300) indicates that the ILCR posed by a site should not exceed a range of 1E-04 to 1E-06. The estimated cancer risks at the Subject Property are within the risk management target cancer risk threshold range (1E-06 to 1E-04) for an indoor commercial/industrial worker.

Risk estimates are provided in Table 1.

6.2 Non-Cancer Hazards
The non-carcinogenic hazard estimate is calculated according to the below equation to arrive at a Hazard Quotient (HQ) for each chemical. The below equation is a modified version of the EPA RSL User’s Guide non-carcinogenic screening level derivation equation indoor worker exposure to air (USEPA, 2022b):1 𝐻𝐻𝐻𝐻 =
𝐸𝐸𝐸𝐸
𝑅𝑅 × 𝐸𝐸𝐸𝐸𝑖𝑖𝑖𝑖𝑖𝑖 × 𝐸𝐸𝐸𝐸𝑖𝑖𝑖𝑖𝑖𝑖 × 𝐸𝐸𝐸𝐸𝑖𝑖𝑖𝑖𝑖𝑖
𝐸𝐸𝐸𝐸𝑖𝑖𝑖𝑖𝑖𝑖 × 1 × 2
Where:

HQ = hazard quotient (unitless)
EPC = indoor air concentration (µg/m3)
RfC = reference concentration (µg/m3)
EFind = exposure frequency (days/year)
EDind = exposure duration (years)
ETind = exposure time (hours)
C1 = 365 days/year
C2 = 24 hours/day
This HHRA assumed default exposure factors in EPA RSL User’s Guide for non-carcinogenic risk assessment of indoor worker exposure to air (USEPA, 2022b) and DTSC Note 1 (DTSC, 2019c).

To assess the potential for non-carcinogenic health effects posed by exposure to multiple constituents, a Hazard Index (HI) approach is used. This approach assumes that non-carcinogenic hazards associated with exposure to more than one constituent are additive (HI = sum of the HQs). Synergistic or antagonistic interactions between constituents are not considered. The HI is then compared to the DTSC threshold of 1 1 Per DTSC Note 3 (DTSC, 2022), DTSC uses the same equations as USEPA RSLs to derive its own DTSC screening levels.
1839
3661.0019L000 HHRA | ROUX | 11
(DTSC, 2015). The non-cancer hazard estimates for a future indoor commercial/industrial worker receptor does not exceed this threshold, as shown below.

Hazard estimates are provided in Table 1. For a more detailed description of the HHRA’s conservative methodology, see the Section 6.3.

6.3 Uncertainty
Risk and hazard estimates resulting from application of this evaluation do not represent absolute estimates at a specific site because generic assumptions for commercial/industrial land use are utilized. Overall, carcinogenic excess lifetime cancer risk ILCR and non-carcinogenic HI presented in the HHRA are based upon conservative assumptions that are intended to be protective of human health by likely overestimating exposure to account for parameter uncertainty (RME exposure scenario). Therefore, the evaluation of current and future exposures in the HHRA is considered conservative.

Reliance on exposure point concentrations to quantify risk estimates inherently introduces uncertainty into risk and hazard estimates, due to uncertainty surrounding site characterization, and heterogeneity. Use of maximum concentrations or 95% UCLs of the mean as EPCs similarly introduces uncertainty, as these statistics almost certainly overestimate actual risk encountered. In particular, the maximum detected concentration was conservatively used to characterize the EPC for the main risk driver PCE. Additionally, for the indoor commercial/industrial worker indoor air exposure scenario, the attenuation factor of 0.03 is a conservative assumption, as DTSC will on occasion allow an attenuation factor of 0.0005 for vapor intrusion calculations.

For the indoor commercial/industrial worker exposure to indoor air pathway, toxicity values were not provided in DTSC HHRA Note 10 or USEPA 2022 RSLs for acetone. Therefore, this compound was not quantitatively evaluated in the HHRA. This omission is considered an area of uncertainty in the HHRA. However, given adoption of numerous conservative assumptions, this uncertainty is not considered to impact conclusions of the HHRA.

Uncertainty also lies in the exposure pathways and receptors evaluated. This limited HHRA only quantitatively evaluated indoor commercial/industrial worker exposure to indoor air. However, risk from the soil and groundwater consumption/ingestion pathways may exist, and other receptors may access the Subject Property in the future. Dermal contact with groundwater at the Subject Property for a construction worker is not considered given the depth to groundwater, but consumption or ingestion of groundwater at the Subject Property is possible as there are no restrictions on groundwater use at the Subject Property. No groundwater data was available, and if groundwater at the Subject Property becomes accessible in the future (through a potable or non-potable groundwater well) groundwater exposure would be a complete pathway 1840
3661.0019L000 HHRA | ROUX | 12
and the HHRA should be revised. Risk was not quantified for a construction worker, resident, outdoor commercial/industrial worker, or trespasser to soils. Even if TPH-soils are removed from the Subject Property in the future, other detected COPCs in soil that were well below screening levels may pose additional minimal, although non-zero, risk and hazard to construction workers, residents, outdoor commercial/industrial workers, and trespassers. The HHRA also did not evaluate the potential future residential exposure to indoor air, and the risk and hazard estimates from the commercial/industrial indoor air pathway evaluated in this HHRA would likely underestimate risk to residential receptors. 1841

FIRST GROVE AIR QUALITY & GREENHOUSE GAS ASSESSMENT
Nicole Morse,
Urban Crossroads, Inc. is pleased to provide the following Air Quality & Greenhouse Gas Assessment for the First Grove (Project), which is located north of E. Philadelphia Street and west of S. Grove Ave in the City of Ontario.

PROJECT OVERVIEW
It is our understanding that the Project is to consist of a 61,867 square foot industrial warehouse building on 4.20 acres (see Exhibit 1).

The Project site land use is currently designated as Business Park under The Ontario Plan (TOP) 2050. The currently adopted General Plan Business Park land use allows for the development of up to 109,817 square feet of business park use, calculated using a floor-to-area ratio (FAR) of 0.60. The Business Park land use designation is defined as “employee-intensive office uses including corporate offices, technology centers, research and development, “clean” industry, light manufacturing, and supporting retail within a business park setting.”

SUMMARY OF FINDINGS
Results of the assessment indicate that the Project would result in a less than significant with respect to air quality and greenhouse gases. 1852

EXHIBIT 1: SITE PLAN

PROJECT AIR QUALITY IMPACTS

AIR QUALITY SETTING

SOUTH COAST AIR BASIN (SCAB)
The Project site is located in the SCAB within the jurisdiction of South Coast Air Quality Management District (SCAQMD) (1). The SCAQMD was created by the 1977 Lewis-Presley Air Quality Management Act, which merged four county air pollution control bodies into one regional district. Under the Act, the SCAQMD is responsible for bringing air quality in areas under its jurisdiction into conformity with federal and state air quality standards. As previously stated, the Project site is located within the SCAB, a 6,745-square mile subregion of the SCAQMD, which includes portions of Los Angeles, Riverside, and San Bernardino Counties, and all of Orange County.

The SCAB is bounded by the Pacific Ocean to the west and the San Gabriel, San Bernardino, and San Jacinto Mountains to the north and east. The Los Angeles County portion of the Mojave Desert Air Basin is bounded by the San Gabriel Mountains to the south and west, the Los Angeles / Kern County border to the north, and the Los Angeles / San Bernardino County border to the east. The Riverside County portion of the Salton Sea Air Basin is bounded by the San Jacinto Mountains in the west and spans eastward up to the Palo Verde Valley.

Regional Climate
The regional climate has a substantial influence on air quality in the SCAB. In addition, the temperature, wind, humidity, precipitation, and amount of sunshine influence the air quality. 1853

15067-02 AQ & GHG Assesment
The annual average temperatures throughout the SCAB vary from the low to middle 60s degrees Fahrenheit (°F). Due to a decreased marine influence, the eastern portion of the SCAB shows greater variability in average annual minimum and maximum temperatures. January is the coldest month throughout the SCAB, with average minimum temperatures of 47°F in downtown Los Angeles and 36°F in San Bernardino. All portions of the SCAB have recorded maximum temperatures above 100°F.

Although the climate of the SCAB can be characterized as semi-arid, the air near the land surface is quite moist on most days because of the presence of a marine layer. This shallow layer of sea air is an important modifier of SCAB climate. Humidity restricts visibility in the SCAB, and the conversion of sulfur dioxide (SO2) to sulfates (SO4) is heightened in air with high relative humidity.

The marine layer provides an environment for that conversion process, especially during the spring and summer months. The annual average relative humidity within the SCAB is 71 percent (%) along the coast and 59% inland. Since the ocean effect is dominant, periods of heavy early morning fog are frequent and low stratus clouds are a characteristic feature. These effects decrease with distance from the coast.

More than 90% of the SCAB’s rainfall occurs from November through April. The annual average rainfall varies from approximately nine inches in Riverside to fourteen inches in downtown Los Angeles. Monthly and yearly rainfall totals are extremely variable. Summer rainfall usually consists of widely scattered thunderstorms near the coast and slightly heavier shower activity in the eastern portion of the SCAB with frequency being higher near the coast.

Due to its generally clear weather, about three-quarters of available sunshine is received in the SCAB. The remaining one-quarter is absorbed by clouds. The ultraviolet portion of this abundant radiation is a key factor in photochemical reactions. On the shortest day of the year there are approximately 10 hours of possible sunshine, and on the longest day of the year there are approximately 14½ hours of possible sunshine.

The importance of wind to air pollution is considerable. The direction and speed of the wind determines the horizontal dispersion and transport of the air pollutants. During the late autumn to early spring rainy season, the SCAB is subjected to wind flows associated with the traveling storms moving through the region from the northwest. This period also brings five to ten periods of strong, dry offshore winds, locally termed “Santa Anas” each year. During the dry season, which coincides with the months of maximum photochemical smog concentrations, the wind flow is bimodal, typified by a daytime onshore sea breeze and a nighttime offshore drainage wind.

Summer wind flows are created by the pressure differences between the relatively cold ocean and the unevenly heated and cooled land surfaces that modify the general northwesterly wind circulation over southern California. Nighttime drainage begins with the radiational cooling of the mountain slopes. Heavy, cool air descends the slopes and flows through the mountain passes and canyons as it follows the lowering terrain toward the ocean. Another characteristic wind regime in the SCAB is the “Catalina Eddy,” a low level cyclonic (counterclockwise) flow centered over Santa Catalina Island which results in an offshore flow to the southwest. On most spring and summer days, some indication of an eddy is apparent in coastal sections.

In the SCAB, there are two distinct temperature inversion structures that control vertical mixing of air pollution. During the summer, warm high-pressure descending (subsiding) air is undercut by a shallow layer of cool marine air. The boundary between these two layers of air is a persistent 1854
Nicole Morse, T&B Planning, Inc.

June 8, 2023

Page 4 of 35 ends

15067-02 AQ & GHG Assesment
marine subsidence/inversion. This boundary prevents vertical mixing which effectively acts as an impervious lid to pollutants over the entire SCAB. The mixing height for the inversion structure is normally situated 1,000 to 1,500 feet above mean sea level.

A second inversion-type forms in conjunction with the drainage of cool air off the surrounding mountains at night followed by the seaward drift of this pool of cool air. The top of this layer forms a sharp boundary with the warmer air aloft and creates nocturnal radiation inversions.

These inversions occur primarily in the winter when nights are longer and onshore flow is weakest. They are typically only a few hundred feet above mean sea level. These inversions effectively trap pollutants, such as nitrogen oxides (NOX) and carbon monoxide (CO) from vehicles, as the pool of cool air drifts seaward. Winter is therefore a period of high levels of primary pollutants along the coastline.

Wind Patterns and Project Location
The distinctive climate of the Project area and the SCAB is determined by its terrain and geographical location. The SCAB is located in a coastal plain with connecting broad valleys and low hills, bounded by the Pacific Ocean in the southwest quadrant with high mountains forming the remainder of the perimeter.

Wind patterns across the south coastal region are characterized by westerly and southwesterly onshore winds during the day and easterly or northeasterly breezes at night. Winds are characteristically light although the speed is somewhat greater during the dry summer months than during the rainy winter season.

Criteria Pollutants
Both the U.S. Environmental Protection Agency (EPA) and the California Air Resources Board (CARB) have established ambient air quality standards for common pollutants. These ambient air quality standards are levels of contaminants representing safe levels that avoid specific adverse health effects associated with each pollutant. The ambient air quality standards cover what are called “criteria” pollutants because the health and other effects of each pollutant are described in criteria documents. The six criteria pollutants are ozone (O3) (precursor emissions include NOX and reactive organic gases (ROG), CO, particulate matter (PM), nitrogen dioxide (NO2), sulfur dioxide (SO2), and lead. Areas that meet ambient air quality standards are classified as attainment areas, while areas that do not meet these standards are classified as nonattainment areas. The Riverside County portion of the SCAB is designated as a nonattainment area for the federal O3 and PM2.5 standards and is also a nonattainment area for the state standards for O3, PM10, and PM2.5.

Toxic Air Contaminants (TAC) Trend
In 1984, as a result of public concern for exposure to airborne carcinogens, CARB adopted regulations to reduce the amount of TAC emissions resulting from mobile and area sources, such as cars, trucks, stationary products, and consumer products. According to the Ambient and Emission Trends of Toxic Air Contaminants in California journal article (2) which was prepared for CARB, results show that between 1990-2012, ambient concentration and emission trends for the seven TACs responsible for most of the known cancer risk associated with airborne exposure in California have declined significantly (between 1990 and 2012). The seven TACs studied include those that are derived from mobile sources: diesel particulate matter (DPM), benzene (C6H6), and 1855

1,3-butadiene (C4H6); those that are derived from stationary sources: perchloroethylene (C2Cl4) and hexavalent chromium (Cr(VI)); and those derived from photochemical reactions of emitted VOCs: formaldehyde (CH2O) and acetaldehyde (C2H4O)1. The decline in ambient concentration and emission trends of these TACs are a result of various regulations CARB has implemented to address cancer risk.

Some people are especially sensitive to air pollution and are given special consideration when evaluating air quality impacts from projects. These groups of people include children, the elderly, and individuals with pre-existing respiratory or cardiovascular illness. Structures that house these persons or places where they gather are defined as “sensitive receptors”. These structures typically include uses such as residences, hotels, and hospitals where an individual can remain for 24 hours. Consistent with the LST Methodology, the nearest land use where an individual could remain for 24 hours to the Project site has been used to determine construction and operational air quality impacts for emissions of PM10 and PM2.5, since PM10 and PM2.5 thresholds are based on a 24-hour averaging time.

Receptors in the Project study area are described below. All distances are measured from the Project site boundary to the outdoor living areas (e.g., backyards) or at the building façade, whichever is closer to the Project site. Receptors in the Project study area are shown on Exhibit 2 under the Localized Construction Emissions section later in the report. • Receptor R1 represents the existing residence at 2125 S Cucamonga Ave, approximately 596 feet southwest of the Project site.
• Receptor R2 represents Home of the Christian-Bethel Church at 1147 E Philadelphia St, approximately 439 feet south of the Project site.
• Receptor R3 represents the existing residence at 1456 E Philadelphia St, approximately 824 feet southeast of the Project site.
• Receptor R4 represents The Grove Apartments at 1110 E Philadelphia St, approximately 756 feet south of the Project site.
• Receptor R5 represents Bon View Elementary at 2121 S Bon View Ave, approximately 1,521 feet west of the Project site.
• Receptor R6 represents Tech Industrial Machine Corp at 2124 S Grove Ave Unit J, adjacent south of the Project site.

REGULATORY BACKGROUND

FEDERAL REGULATIONS
The EPA is responsible for setting and enforcing the national ambient air quality standards (NAAQS) for O3, CO, NOX, SO2, PM10, and lead (Pb) (3). The EPA has jurisdiction over emissions sources that are under the authority of the federal government including aircraft, locomotives, 1 It should be noted that ambient DPM concentrations are not measured directly. Rather, a surrogate method using the coefficient of haze (COH) and elemental carbon (EC) is used to estimate DPM concentrations. 1856

and emissions sources outside state waters (Outer Continental Shelf). The EPA also establishes emission standards for vehicles sold in states other than California. Automobiles sold in California must meet the stricter emission requirements of CARB.

The Federal Clean Air Act (CAA) was first enacted in 1955 and has been amended numerous times in subsequent years (1963, 1965, 1967, 1970, 1977, and 1990). The CAA establishes the federal air quality standards, the NAAQS, and specifies future dates for achieving compliance (4). The CAA also mandates that each state submit and implement state implementation plans (SIPs) for local areas not meeting these standards. These plans must include pollution control measures that demonstrate how the standards will be met.

The 1990 amendments to the CAA that identify specific emission reduction goals for areas not meeting the NAAQS require a demonstration of reasonable further progress toward attainment and incorporate additional sanctions for failure to attain or to meet interim milestones. The sections of the CAA most directly applicable to the development of the Project site include Title I (Non-Attainment Provisions) and Title II (Mobile Source Provisions) (5) (6). Title I provisions were established with the goal of attaining the NAAQS for the following criteria pollutants O3, NO2, SO2, PM10, CO, PM2.5, and Pb. The NAAQS were amended in July 1997 to include an additional standard for O3 and to adopt a NAAQS for PM2.5.

Mobile source emissions are regulated in accordance with Title II provisions. These provisions require the use of cleaner burning gasoline and other cleaner burning fuels such as methanol and natural gas. Automobile manufacturers are also required to reduce tailpipe emissions of hydrocarbons and NOX. NOX is a collective term that includes all forms of NOX which are emitted as byproducts of the combustion process.

CALIFORNIA REGULATIONS
CARB
The CARB, which became part of the California EPA (CalEPA) in 1991, is responsible for ensuring implementation of the California Clean Air Act (AB 2595), responding to the federal CAA, and for regulating emissions from consumer products and motor vehicles. AB 2595 mandates achievement of the maximum degree of emissions reductions possible from vehicular and other mobile sources in order to attain the state ambient air quality standards by the earliest practical date. The CARB established the California ambient air quality standards (CAAQS) for all pollutants for which the federal government has NAAQS and, in addition, establishes standards for SO4, visibility, hydrogen sulfide (H2S), and vinyl chloride (C2H3Cl). However, at this time, H2S and C2H3Cl are not measured at any monitoring stations in the SCAB because they are not considered to be a regional air quality problem. Generally, the CAAQS are more stringent than the NAAQS (7) (8).

Local air quality management districts, such as the SCAQMD, regulate air emissions from stationary sources such as commercial and industrial facilities. All air pollution control districts have been formally designated as attainment or non-attainment for each CAAQS.

Serious non-attainment areas are required to prepare Air Quality Management Plans (AQMP) that include specified emission reduction strategies in an effort to meet clean air goals. These plans are required to include:
