Executive Summary
This report evaluates potential local and regional air quality impacts associated with the proposed Sycamore Hills Distribution Center project (project) in city of Riverside, California, north of Alessandro Boulevard and east of Barton Street (Assessor Parcel Numbers 263-060- 022, 263-060-024, 263-060-026). The project proposes subdividing the site into two parcels (Parcels 1 and 2), and three lettered parcels (Parcels A, B, and C). Each parcel is proposed to be developed with a high-cube transload short-term warehouse building (Buildings A and B).

Building A, a 400,000-square-foot warehouse, would be constructed on Parcel 1. Building B, a 203,100- square-foot warehouse, would be constructed on Parcel 2. Associated improvements include parking, fir e lanes, fencing and walls (including retaining walls), landscaping, and water quality treatment areas. Parcels A and Parcel B consist of existing Restricted Property of natural land. Parcel C would include a trailhead parking lot for access to the Sycamore Canyon Wilderness Park.

This analysis evaluates the significance of the proposed project in accordance with National Environmental Policy Act, the California Environmental Quality Act, and guidance from the South Coast Air Quality Management District ( SCAQMD). The project was evaluated to determine if it would (1) be inconsistent with the applicable air quality plan, (2) result in cumulative impacts to air quality, (3) impact sensitive receptors, or (4) expose a substantial number of people to objectionable odors.

The SCAQMD prepared the 2016 Air Quality Management Plan (AQMP), which represents its contribution to the State Implementation Plan , to outline the district’s strategy for achieving attainment of federal and state Ambient Air Quality Standards (AAQS). The 2016 AQMP provides an overview of air quality and sources of air pollution, and identifies the pollution-control measures needed to meet clean air standards. The project would be consistent with the land use and zoning designations and would support the development goals of the Sycamore Canyon Business Park Specific Plan. The project would also be consistent with the growth assumptions of the 2016 AQMP. Additionally, the project would not result in an air quality violation. Therefore, the project would not conflict with or obstruct the implementation of the 2016 AQMP or applicable portions of the State Implementation Plan (SIP).

Implementation of the project would result in air quality emission s associated with the construction and operation of the project. As calculated in this analysis, project construction and operation would not exceed the SCAQMD’s thresholds of significance. Therefore, as project construction and operation emissions would b e below these limits, project construction and operation would not result in regional emissions that would exceed the National AAQS (NAAQS) or California AAQS (CAAQS) or contribute to existing violations.

Therefore, the project would result in a less than significant impact.

Project construction and operational emissions would not exceed the SCAQMD’s Localized Significance Thresholds. Thus, the project would not result in localized emissions that exceed Air Quality Analysis

the NAAQS or CAAQS or expose nearby sensitive receptors to unhealthy pollutant concentrations. The project would result in a less than significant local air quality impact.

The potential for an odor impact is dependent on a number of variables including the nature of the odor source, distanc e between the receptor and odor source, and local meteorological conditions. During construction, potential odor sources associated with the project include diesel exhaust associated with construction equipment. Diesel exhaust may be noticeable; however, construction activities would be temporary, and would dissipate without affecting a substantial number of people. The project does not include a use that is anticipated to generate substantial odors. Impacts would be less than significant.

1.0 Introduction
This report evaluates the significance of air quality impacts associated with the proposed Sycamore Hills Distribution Center project (project) . T his report characterizes existing conditions at the project site and in the region, identifies applicable rules and regulations, and assesses impacts to air quality from construction and operation of the proposed project.

The signi ficance of potential air quality impacts is assessed based on the air quality thresholds defined by the regional air quality management district, the South Coast Air Quality Management District (SCAQMD).

Air pollution affects all southern Californians. Effects can include increased respiratory infections, increased discomfort, missed days from work and school, and increased mortality.

Polluted air also damages agriculture and our natural environment.

The state of California is divided geographically into 15 air basins for managing the air resources of the state on a regional basis. Areas within each air basin are considered to share the same air masses and, therefore, are expected to have similar ambient air quality. The project site is located within the South Coast Air Basin. The project area portion of the South Coast Air Basin is currently classified as a federal non -attainment area for ozone (O 3) and
particulate matter less than 2.5 microns (PM2.5), and a state non-attainment area for ozone, particulate matter less than 10 microns (PM10), and PM2.5.

Air quality impacts can result from the construction and operation of the project.

Construction impacts are short term and result from fugitive dust, equipment exhaust, and indirect effects associated with construction workers and deliveries. Operational impacts can occur on two levels: regional impacts resulting from growth -inducing development, or local hot-spot effects stemming from sensitive receivers being placed close to highly congested roadways. In the case of this project, operational impacts would be primarily due to emissions to the South Coast Air Basin from mobile sources associated with vehicular travel along the roadways within the project area.

The analysis of impacts is based on federal and state Ambient Air Quality Standards (AAQS) and is assessed in accordance with the guidelines, policies, and standards established by the City of Riverside (City) and the SCAQMD. Project compatibility with the adopted air quality plan for the area is also assessed. Measures are recommended, as required, to reduce potentially significant impacts.

2.0 Project Description
The proposed project is to con struct an industrial warehouse development on three parcels (Assessor Parcel Numbers 263-060-022, 263-060-024, 263-060-026), totaling 48.64 gross acres. The pro perty is located at the northeast corner of Barton Street and Alessandro Boulevard in the City of Riverside, immediately south of the Sycamore Canyon Wilderness Park. The property is spread in an east to west direction with natural rolling land descending gradually from a west to east direction. There are two jurisdictional drainages on the site .

The undeveloped parcels are covered with a low to moderate growth of vegetation cover consisting of natural grasses and weeds with some granitic rock outcrops . Figure 1 shows the regional location. Figure 2 shows an aerial photograph of the project site and vicinity.

The project proposes subdividing the site into two parcels (Parcels 1 and 2), and three lettered parcels (Parcels A, B, and C). Each parcel is proposed to be developed with a high cube transload short -term warehouse building (Buildings A and B). Building A, a 400,000-squarefoot warehouse, would be constructed on Parcel 1. Building B, a 203,100-square-foot warehouse, would be constructed on Parcel 2. Associated improvements include parking, fire lanes, fencing and walls (including retaining walls), landscaping, and water quality treatment areas.

Parcels A and Parcel B consist of existing Restricted Property of natural land, with a supporting jurisdictional feature, totaling approximately 11.6 acres. A 0.67 -acre driveway would be constructed through the Restricted Property to provide street access from Alessandro Boulevard to Parcel 1, which would reduce the Restricted Property to 10.93 acres.

However, 1.44 acres would be added to Parcel A to mitigate this loss, resulting in a total of

12.37 acres of Restricted Property (net gain of 0.77 acre). A Conservation Easement is proposed to be placed over the amended 12.37 acres of Restricted Property.

A trailhead parking lot is proposed on Parcel C, totaling 1.18 acres, for access to the Sycamore Canyon Wilderness Park. I mprovements include a parking lot, sidewalk, shade structure, bike rack, drinking fountain, fencing, and a Fire Department and access gate. Parcel C will be dedicated to the City. Figure 3 shows the site plan.

3.0 Regulatory Framework

3.1 Federal Regulations

3.1.1 Ambient Air Quality Standards
AAQS represent the maximum levels of background pollution considered safe, with an adequate margin of safety, to protect the public health and welfare. The federal Clean Air Act (CAA) was enacted in 1970 and amended in 1977 and 1990 [42 United States Code (USC) 7401] for the purposes of protecting and enhancing the quality of the nation’s air resources to benefit public health, welfare, and productivity. In 1971, in order to achieve the purposes of Section 109 of the CAA [42 USC 7409], the U.S. Environmental Protection Agency ( U.S.

EPA) developed primary and secondary National Ambient Air Quality Standards (NAAQS).

Six criteria pollutants of primary concern have been designated: ozone, carbon monoxide (CO), sulfur dioxide (SO 2), nitrogen dioxide (NO 2), lead (Pb), and respirable particulate matter (PM10 and PM2.5). The primary NAAQS “. . . in the judgment of the Administrator, based on such criteria and allowing an adequate margin of safety, are requisite to protect the public health . . . ” and the secondary standards “. . . protect the public welfare from any known or anticipated adverse effects associated with the presence of such air pollutant in the ambient air” [42 USC 7409(b)(2)]. The primary NAAQS were established, with a margin of safety, considering long -term exposure for the most sensitive groups in the general population (i.e., children, senior citizens, and people with breathing difficulties). The NAAQS are presented in Table 1 (California Air Resources Board [CARB] 2016).

An air basin is designated as either attainment or non-attainment for a particular pollutant.

Once a non- attainment area has achieved the AAQS for a particular pollutant, it is re - designated as an attainment area for that pollutant. To be redesignated, the area must meet air quality standards for three consecutive years. After re-designation to attainment, the area is known as a maintenance area and must develop a 10-year plan for continuing to meet and maintain air quality standards, as well as satisfy other requirements of the federal CAA. The project area of the South Coast Air Basin is a non-attainment area for the federal ozone and PM

2.5 standards.

Table 1
Ambient Air Quality Standards
ppm = parts per million; ppb = parts per billion; µg/m3 = micrograms per cubic meter; – = not applicable. 1 California standards for ozone, carbon monoxide (except 8-hour Lake Tahoe), sulfur dioxide (1 and 24 hour), nitrogen dioxide, particulate matter (PM10, PM2.5, and visibility reducing particles), are values that are not to be exceeded. All others are not to be equaled or exceeded. California ambient air quality standards are listed in the Table of Standards in Section 70200 of Title 17 of the California Code of Regulations. 2 National standards (other than ozone, particulate matter, and those based on annual arithmetic mean) are not to be exceeded more th an once a year. The ozone standard is attained when the fourth highest 8 -hour concentration measured at each site in a year, averaged over three years, is equal to or less than the standard. For PM 10, the 24-
hour standard is attained when the expected number of days per calendar year with a 24-hour average concentration above 150 µg/m3 is equal to or less than one. For PM2.5, the 24-hour standard is attained when 98 percent of the daily concentrations, averaged over three years, are equal to or less than the standard. Contact the U.S. EPA for further clarification and current national policies.
3 Concentration expressed first in units in which it was promulgated. Equivalent units given in parentheses are based upon a reference temperature of 25°C and a reference pressure of 760 torr. Most measurements of air quality are to be corrected to a reference temperature of 25°C and a reference pressure of 760 torr; ppm in this table refers to ppm by volume, or micromoles of pollutant per mole of gas.
4 Any equivalent measurement method which can be shown to the satisfaction of the Air Resources Board to give equivalent results at or near the level of the air quality standard may be used. 5 National Primary Standards: The levels of air quality necessary, with an adequate margin of safety to protect the public health.
6 National Secondary Standards: The levels of air quality necessary to protect the public welfare from any known or anticipated adverse effects of a pollutant.
7 Reference method as described by the U.S. EP A. An “equivalent method” of measurement may be used but must have a “consistent relationship to the reference method” and must be approved by the U.S. EPA. 8 On October 1, 2015, the national 8-hour ozone primary and secondary standards were lowered from 0.075 to 0.070 ppm.
9 On December 14, 2012, the national annual PM2.5 primary standard was lowered from 15 µg/m3 to 12.0 µg/m3. The existing national 24-hour PM2.5 standards (primary and secondary) were retained at 35 µg/m 3, as was the annual secondary standards of 15 µg/m 3. The existing 24 -hour PM10 standards (primary and secondary) of 150 µg/m 3 also were retained. The form of the annual primary and secondary standards is the annual mean, averaged over 3 years. 10 To attain the 1-hour national standard, the 3-year average of the annual 98th percentile of the 1-hour daily maximum concentrations at each site must not exceed 100 ppb. Note that the national standards are in units of ppb. California standards are in units of ppm. To directly compare the national standards to the California standards the units can be converted from ppb to ppm. In this case, the national standard of 100 ppb is identical to 0.100 ppm. 11 On June 2, 2010, a new 1-hour SO2 standard was established and the existing 24-hour and annual primary standards were revoked. To attain the 1-hour national standard, the 3-year average of the annual 99th percentile of the 1-hour daily maximum concentrations at each site must not exceed 75 ppb. The 1971 SO2 national standards (24-hour and annual) remain in effect until one year after an area is designated for the 2010 standard, except that in areas designated non-attainment for the 1971 standards, the 1971 standards remain in effect until implementation plans to attain or maintain the 2010 standards are approved.

Note that the 1 -hour national standard is in units of ppb. California standards are in units of ppm. To directly compare the 1-hour national standard to the California standard the units can be converted to ppm. In this case, the national standard of 75 ppb is identical to 0.075 ppm.
12 The Air Resources Board has identified lead and vinyl chloride as ‘toxic air contaminants’ with no threshold level of exposure for adverse health effects determined. These actions allow for the implementat ion of control measures at levels below the ambient concentrations specified for these pollutants. 13 The national standard for lead was revised on October 15, 2008 to a rolling 3-month average. The 1978 lead standard (1.5 μg/m3 as a quarterly average) remains in effect until one year after an area is designated for the 2008 standard, except that in areas designated non -attainment for the 1978 standard, the 1978 standard remains in effect until implementation plans to attain or maintain the 2008 standard are approved. 14 In 1989, the ARB converted both the general statewide 10- mile visibility standard and t he Lake Tahoe 30 -mile visibility standard to instrumental equivalents, which are “extinction of 0.23 per kilometer” and “extinction of 0.07 per kilometer” for the statewide and Lake Tahoe Air Basin standards, respectively.

3.1.2 General Conformity Rule
The General Conformity Rule requires that federal agencies demonstrate that actions would conform to the applicable State Implementation Plan (SIP), by either determining that the action is exempt from the General Conformity Rule requirements or subject to a formal conformity determination. This requires analysis of the total direct and indirect emissions of criteria pollutants and their precursors for which an area is designated non -attainment or covered by a maintenance plan. The total direct and indirect emissions are the net emission increases in the non- attainment or maintenance area caused by the action. The emissions must be reasonably foreseeable at the time the conformity determination is made. For indirect emissions, the federal agency also must be able to practicably control the emissions based upon the agency’s continuing program responsibility. If the emissions resulting from an action would not exceed applicable General Conformity de minimis levels, then the action would conform to the applicable SIP and no further analysis would be required. If emissions resulting from an action would exceed applicable General Conformity de minimis levels, then a formal Air Quality Conformity Analysis would be required.

3.2 State Regulations

3.2.1 Criteria Pollutants
The CARB has developed the California Ambient Air Quality Standards ( CAAQS) and generally has set more stringent limits on the criteria pollutants than the NAAQS (see Table 1). In addition to the federal criteria pollutants, the CAAQS also specify standards for visibility-reducing particles, sulfates, hydrogen sulfide, and vinyl chloride (see Table 1).

Similar to the federal CAA, the state classifies as either “attainment” or “non -attainment” areas for each pollutant based on the comparison of measured data with the CAAQS. The project area of the South Coast Air Basin is a non-attainment area for the state ozone, PM10, and PM2.5 standards.

3.2.2 Toxic Air Contaminants
The public’s exposure to toxic air contaminants (TACs) is a significant public health issue in California. Diesel-exhaust particulate matter emissions have been established as TACs. In 1983, the California Legislature enacted a program to identify the health effects of TACs and to reduce exposure to these contaminants to protect the public health (Assembly Bill [AB] 1807: Health and Safety Code Sections 39650–39674). The Legislature established a two-step process to address the potential health effects from TACs. The first step is the risk assessment (or identification) phase.

The second step is the risk management (or control) phase of the process.

The California Air Toxics Program establishes the process for the identification and control of TACs and includes provisions to make the public aware of significant toxic exposures and for reducing risk. Additionally, the Air Toxics "Hot Spots" Information and Assessment Act Air Quality Analysis
Sycamore Hills Distribution Project

Page 11 ends

(AB 2588, 1987, Connelly Bill) was enacted in 1987 and requires stationary sources to report the types and quantities of certain substances routinely released into the air.

The goals of the Air Toxics "Hot Spots" Act are to collect emission data, to identify facilities having localized impacts, to ascertain health risks, to notify nearby residents of significant risks, and to reduce those significant risks to acceptable levels.

The Children’s Environmental Health Protection Act, California Senate Bill 25 (Chapter 731, Escutia, Statutes of 1999), focuses on children’s exposure to air pollutants. The act requires CARB to review its air quality standards from a children’s health perspective, evaluate the statewide air monitoring network, and develop any additional air toxic control measures needed to protect children’s health. Locally, toxic air pollutants are regulated by the SCAQMD through Regulation XIV. Of particular concern statewide are diesel-exhaust particulate matter emissions. Diesel- exhaust particulate matter was established as a TAC in 1998, and is estimated to represent a majority of the cancer risk from TACs statewide (based on the statewide average). Diesel exhaust is a complex mixture of gases, vapors, and fine particles. This complexity makes the evaluation of health effects of diesel exhaust a complex scientific issue. Some of the chemicals in diesel exhaust, such as benzene and formaldehyde, have been previously identified as TACs by the CARB and are listed as carcinogens either under the state's Proposition 65 or under the federal Hazardous Air Pollutants program.

Following the identification of diesel particulate matter (DPM) as a TAC in 1998, CARB has worked on developing strategies and regulations aimed at reducing the risk from DPM. The overall strategy for achieving these reductions is found in the Risk Reduction Plan to Reduce Particulate Matter Emissions from Diesel-Fueled Engines and Vehicles (CARB 2000). A stated goal of the plan is to reduce the statewide cancer risk arising from exposure to DPM by 85 percent by 2020.

In April 2005, CARB published the Air Quality and Lan d Use Handbook: A Community Health Perspective (CARB 2005). The handbook makes recommendations directed at protecting sensitive land uses from air pollutant emissions while balancing a myriad of other land use issues (e.g., housing, transportation needs, e conomics, etc.). It notes that the handbook is not regulatory or binding on local agencies and recognizes that application takes a qualitative approach. As reflected in the CARB Handbook, there is currently no adopted standard for the significance of health effects from mobile sources. Therefore, the CARB has provided guidelines for the siting of land uses near heavily traveled roadways. Of pertinence to this study, the CARB guidelines indicate that siting new sensitive land uses within 500 feet of a freewa y or urban roads with 100,000 or more vehicles/day should be avoided when possible.

As an ongoing process, CARB will continue to establish new programs and regulations for the control of diesel particulate and other air-toxics emissions as appropriate. The continued development and implementation of these programs and policies will ensure that the public’s exposure to DPM will continue to decline.

3.2.3 State Implementation Plan
The State Implementation Plan (SIP) is a collection of documents that set forth the state’s strategies for achieving the NAAQS. In California, the SIP is a compi lation of new and previously submitted plans, programs (such as air quality management plans, monitoring, modeling, permitting, etc.), district rules, state regulations, and federal controls. The CARB is the lead agency for all purposes related to the SIP under state law. Local air districts and other agencies, such as the Department of Pesticide Regulation and the Bureau of Automotive Repair, prepare SIP elements and submit them to CARB for review and approval.

The CARB then forwards SIP revisions to the U.S. EPA for approval and publication in the Federal Register. All of the items included in the California SIP are listed in the Code of Federal Regulations (CFR) at 40 CFR 52.220.

3.2.4 The California Environmental Quality Act
Section 15125(d) of the Cali fornia Environmental Quality Act (CEQA) Guidelines requires discussion of any inconsistencies between the project and applicable general plans and regional plans, including the applicable air quality attainment or maintenance plan (or SIP).

3.3 Regional Regulations

3.3.1 South Coast Air Quality Management District
The SCAQMD is the air pollution control agency in the Basin. The role of the local SCAQMD is to protect the people and the environment of the Basin from the effects of air pollution.

SCAQMD share s responsibility with CARB for ensuring that NAAQS and CAAQS are achieved and maintained within the South Coast Air Basin. As the SCAQMD is designated as a nonattainment area for state air quality standards for 8 -hour ozone, PM10, and PM2.5, SCAQMD periodically prepares air quality management plans (AQMPs) outlining measures to reduce these pollutants. The most recent AQMP is the 2016 Air Quality Management Plan (2016 AQMP).

3.3.2 SCAQMD Amicus Brief
A recent Supreme Court of California decision , Sierra Club v. County of Fresno (2019) 6 Cal.5th 502 (“Friant Ranch ”; California Supreme Court 2019), found that the EIR prepared for the Friant Ranch Specific Plan was inadequate because it did not relate the expected adverse air quality impacts to likely health consequences, or explain why it is not feasible to provide such an analysis. In response, the SCAQMD has provided amicus briefs explaining the difficulties in providing correlation between regional pollutant emissions and human health. Since the project wou ld result in emissions of criteria pollutants, the California Supreme Court decision and the SCAQMD’s amicus briefs are relevant to the project.

The California Supreme Court conceded that an explanation of the connection between an individual project’s pollutant emissions in excess of thresholds and human health effects may Air Quality Analysis
Sycamore Hills Distribution Project

Page 13 ends

not be possible given the current state of environmental science modeling. However, the California Supreme Court concluded that the Friant Ranch Project EIR itself must expl ain, in a manner reasonably calculated to inform the public, the scope of what is and is not yet known about the effect of the project’s significant and unavoidable air quality impacts on human health. The specific language provided by the Court is provided below.

The EIR fails to provide an adequate discussion of health and safety problems that will be caused by the rise in various pollutants resulting from the Project’s development. At this point, we cannot know whether the required additional analysis w ill disclose that the Project’s effects on air quality are less than significant or unavoidable, or whether that analysis will require reassessment of proposed mitigation measures. Absent an analysis that reasonably informs the public how anticipated air quality effects will adversely affect human health, an EIR may still be sufficient if it adequately explains why it is not scientifically feasible at the time of drafting to provide such an analysis.

With regard to the analysis of air quality -related health impacts, the SCAQMD has stated that “EIRs must generally quantify a project’s pollutant emissions, but in some cases it is not feasible to correlate these emissions to specific, quantifiable health impacts (e.g., premature mortality; hospital admissions).” In such cases, a general description of the adverse health impacts resulting from the pollutants at issue may be sufficient.

The SCAQMD has further stated that from a scientific standpoint, it takes a large amount of additional precursor emissions to cause a modeled increase in ambient ozone levels over an entire region. SCAQMD further acknowledges that it may be feasible to analyze air quality related health impacts for projects on a regional scale with very high emissions of oxides of nitrogen (NOx) and volatile organic compounds ( VOCs), where impacts are regional. The example SCAQMD provided was for proposed Rule 1315, which authorized various newly permitted sources to use offsets from the SCAQMD’s “internal bank” of emission reductions.

The CEQA analysis accounted for essentially all of the increases in emissions due to new or modified sources in the District between 2010 and 2030, or approximately 6,620 pounds per day of NOx and 89,947 pounds per day of VOC, to expected health outcomes from ozone and particulate matter (e.g., 20 premature deaths per year and 89,947 school absences in the year 2030 due to ozone).

3.3.3 Multiple Air Toxics Exposure Study
The Multiple Air Toxics Exposure Study (MATES) is a monitoring and evaluation study conducted in the South Coast Air Basin. The MATES I V study, which is a an update of previous studies, includes a fixed site monitoring program with 10 stations, an inventory of TACs, and a modeling effort to characterize risk across the South Coast Air Basin. The purpose of the MATES IV fixed site monitoring is to characterize long-term regional air toxics levels in residential and commercial areas. MATES IV predicts that the excess cancer risk for the project area is 754.23 in a million (SCAQMD 2015). The MATES IV study represents the baseline health risk for a cumulative analysis. The MATES V update is currently being conducted (SCAQMD 2017).

4.0 Environmental Setting

4.1 Site Conditions
The project site is currently undeveloped. A storage facility is located at the southwest project boundary, a water treatment plant is located to the west, the Alessandro Business Center is located to the east, and retail/commercial uses are located to the south. The Sycamore Canyon Wilderness Park is located directly north of the project site. The Sycamore Canyon Wilderness Park is approximately 1,500 acres of open space containing vital biological resources and wildlife habitat areas, inclu ding rare local species. Multi-family land uses are located southwest of the project site, and single-family uses are located south of the retail/commercial uses south of the project site. These single-family uses are within the jurisdiction of the County of Riverside.

4.2 Regional Setting and Climate
The project site is located approximately 37 miles northeast of the Pacific Ocean in the city of Riverside in north western Riverside County. Air quality in the County is influenced by both topographical and m eteorological conditions. The project site is located in western Riverside County between the Santa Ana Mountains and the San Jacinto Mountains.

The project area, like other inland valley areas in southern California, has a Mediterranean climate characterized by warm, dry summers and mild, wet winters. The March Field climate monitoring station (ID 045326) is approximately 2.5 miles southeast of the project site and the Riverside Fire Station 3 climate monitoring station (ID 047470) is approximately 5 miles northwest of the project site . Based on measurements taken at these climate monitoring stations, the average annual precipitation is 8 to 10 inches, falling primarily from November to April (Western Regional Climate Center 2018). Annual temperatures in the project area average about 64 degrees Fahrenheit (°F), winter low temperatures average about 40°F, and summer high temperatures average about 92°F.

The dominant meteorological feature affecting the region is the Pacific High Pressure Zone, which produces the prevailing westerly to northwesterly winds. These winds tend to blow pollutants away from the coast toward the inland areas. Consequently, air quality near the coast is generally better than that which occurs at the base of the coastal mountain range.

The prevailing westerly wind pattern is sometimes interrupted by regional “Santa Ana” conditions. A Santa Ana occurs when a strong high pressure develops over the Nevada–Utah area and overcomes the prevailing westerly coastal winds, sending strong, steady, hot, dry northeasterly winds over the mountains and out to sea.

4.3 Existing Air Quality
As discussed, the State of California is divided geographically into 15 air basins for managing the air resources of the state on a regional basis. The project is located in the South Coast Air Air Quality Analysis
Sycamore Hills Distribution Project

Page 15 ends

Basin. The South Coast Air Basin includes Orange County and the non-desert portions of Los Angeles, Riverside, and San Bernardino counties. The Basin is designated as in attainment or unclassifiable attainment (expected to be meeting the standard despite a lack of monitoring data) for all federal air quality standards except 8- hour ozone and PM 2.5 standards. The South Coast Air Basin is designated as in nonattainment for state air quality standards for 8 -hour ozone and PM 2.5, and additionally is in nonattainment of state PM 10 standards.

Air quality is commonly expressed as the number of days in which air pollution levels exceed state standards set by CARB or federal standards set by the U.S. EPA. The SCAQMD maintains 41 active air quality monitoring sites located throughout the South Coast Air Basin including eight active sites in Riverside County. Air pollutant concentr ations and meteorological information are continuously recorded at these stations. Measurements are then used by scientists to help forecast daily air pollution levels.

The Rubidoux –Mission Boulevard monitoring st ation, located at 5888 Mission B oulevard approximately 8 miles northwest of the project site, is the nearest monitoring station. The Rubidoux–Mission Boulevard monitoring station measures ozone, NO 2, PM 10, and PM 2.5.

Table 2 provides a summary of measurements collected at the monitoring station for the years 2014 through 2018.

4.4 Health Effects

4.4.1 Ozone
Ozone is the primary component of smog. Ozone is not directly emitted into the air but is formed through complex chemical reactions between precursor emissions of NO X and ROG in
the presence of sunlight. The adverse health effects associated with exposure to ozone pertain primarily to the respiratory system. Scientific evidence indicates that ambient levels of ozone affect not only sensitive receptors, such as asthma sufferers and children, but healthy adults as well. Exposure to ozone has been found to significantly alter lung functions by increasing respiratory rates and pulmonary resistance, decreasing tidal volume s (the amount of air inhaled and exhaled), and impairing respiratory mechanics. Symptomatic responses include such symptoms as throat dryness, chest tightness, headache, and nausea. About half of smog- forming emissions come from automobiles.

4.4.2 Carbon Monoxide
Carbon monoxide is a colorless, odorless gas that is formed when carbon in fuel is not burned completely. CO enters the bloodstream through the lungs by combining with hemoglobin, which normally supplies oxygen to the cells. However, CO combines with hemoglobin much more readily than oxygen does, resulting in a drastic reduction in the amount of oxygen available to the cells. Adverse health effects associated with exposure to CO concentrations include such symptoms as dizziness, headaches, and fatigue. CO exposure is especially harmful to individuals who suffer from cardiovascular and respiratory diseases (U.S. EPA 2016).

4.4.3 Nitrogen Dioxide
Nitrogen dioxide is a brownish, highly reactive gas that is present in all urban environments.

The major human-made sources of NO2 are combustion devices, such as boilers, gas turbines, and mobile and stationary reciprocating internal combustion engines. Inhalation is the most common route of exposure to NO

2. Because NO 2 has relatively low solubility in water, the principal site of toxicity is in the lower respiratory tract. The severity of the adverse health effects depends primarily on the concentration inhaled rather than the duration of exposure.

An individual may experience a variety of acute symptoms, including coughing, difficu lty with breathing, vomiting, headache, and eye irritation during or shortly after exposure. After a period of approximately 4 to 12 hours, an exposed individual may experience chemical pneumonitis or pulmonary edema with breathing abnormalities, cough, cyanosis, chest pain, and rapid heartbeat.

4.4.4 Sulfur Dioxide
Sulfur dioxide is a combustion product, with the primary source being power plants and heavy industries that use coal or oil as fuel. SO2 is also a product of diesel engine combustion.

The healt h effects of SO 2 include lung disease and breathing problems for people with asthma. SO2 in the atmosphere contributes to the formation of acid rain.

4.4.5 Particulate Matter
Particulate matter is a complex mixture of microscopic solid or liquid particles including chemicals, soot , and dust. Anthropogenic sources of direct particulate emissions include crushing or grinding operations, dust stirred up by vehicle traffic, and combustion sources such as motor vehicles, power plants, wood burning, forest fires, agricultural burning and industrial processes. Additionally, indirect emissions may be formed when aerosols react with compounds found in the atmosphere.

Health studies have shown a significant association between exposure to particulate matter and premature death in people with heart or lung diseases. Other important effects include aggravation of respiratory and cardiovascular disease, lung disease, decreased lung function, asthma attacks, and certain cardiovascular problems such as heart attacks a nd irregular heartbeat (U.S. EPA 2016).

As its properties vary based on the size of suspended particles, particulate matter is generally categorized as particulate matter with an aerodynamic diameter of 10 microns or less (PM 10)
or particulate matter with an aerodynamic diameter of 2.5 microns or less (PM2.5).

PM10, occasionally referred to as “inhalable coarse particles ,” has an aerodynamic diameter of about one-seventh of the diameter of a human hair. High concentrations of PM10 are often found near roadways, construction, mining, or agricultural operations.

Air Quality Analysis
Sycamore Hills Distribution Project

Page 18 ends

PM2.5, occasionally referred to as “inhalable fine particles,” has an aerodynamic diameter of about one-thirtieth of the diameter of a human hair. PM2.5 is the main cause of haze in many parts of the United States. Federal standards applicable to PM2.5 were first adopted in 1997.

4.4.6 Lead
Lead is a stable compound that persists and accumulates both in the environment and in animals. Fetuses, infants, and children are more sensitive than others to the adverse effects of lead exposure. Exposure to low levels of lead can adversely affect the development and function of the central nervous system, leading to learning disorders, distractibility, inability to follow simple commands, and lower intelligence quotient. In adults, increased lead levels are associated with increased blood pressure. Lead poisoning can cause anemia, lethargy, seizures, and death; although it appears that there are no direct effects of lead on the respiratory system.

The lead used pr ior to the late 1980s in gasoline anti -knock additives represented a major source of lead emissions to the atmosphere. The U.S. EPA began working to reduce lead emissions soon after its inception, issuing the first reduction standards in l973, which called for a gradual phase down of lead to one tenth of a gram per gallon by l986. The average lead content in gasoline in 1973 was 2 to 3 grams per gallon or about 200,000 tons of lead a year.

In 1975, passenger cars and light trucks were manufactured with a more elaborate emission control system, which included a catalytic converter that required lead- free fuel. In l995, leaded fuel accounted for only 0.6 percent of total gasoline sales and less than 2,000 tons of lead per year. Effective January 1, 1996, the CAA banned the sale of the small amount of leaded fuel that was still available in some parts of the country for use in on -road vehicles.

Environmental exposure to lead has significantly decreased due to the near elimination of the use of leaded gasoline; metal processing is currently the primary source of lead emissions.

5.0 Significance Criteria
The significance t hresholds used in this analysis were based , in part, on the CAA requirements, Appendix G of the CEQA Guidelines as well as guidance from the SCAQMD for assessing air quality impacts. The following thresholds were used to determine significance of air quality impacts associated with the project. A dverse air quality impacts would occur if implementation of the project 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 nonattainment under an applicable federal or state ambient air quality standards.
• Expose sensitive receptors to substantial pollutant concentrations. • Result in other emissions (such as those leading to odors) adversely affecting a substantial number of people.

5.1 General Conformity Rule
The project site is located within t he South Coast Air Basin , which is a federal non- attainment area for 8-hour ozone and PM2.5, as well as a maintenance area for CO and PM10.

Therefore, the General Conformity Rule is applicable to the project emissions of CO and ozone precursors ( reactive organic gases [ ROG] and NO X). The General Conformity de minimis levels applicable to the South Coast Air Basin are shown in Table 3.

Table 3

Particulate Matter (PM2.5) Non-attainment
(Serious) 70
SOURCES: 40 CFR 93.53(b)(1) and 40 CFR 93.53(b)(2)
VOC = volatile organic compound

As discussed in Section 3.1.2, the General Conformity Rule requires that federal agencies demonstrate that actions would conform to the applicable SIP. Therefore the first significance criteria, whether the project would obstruct or conflict with the implementation of the applicable air quality plan, is addressed by the assessment of General Conformity Rule compliance. The applicable General Conformity de minimis levels are established based on the attainment status of the project region. Therefore the second significance criteria, whether the project would result in a cumu latively considerable net increase of any criteria pollutant for which the project region is a non-attainment area, is also addressed by the assessment of General Conformity Rule compliance.

5.2 Regional Significance Thresholds
This air quality analysis is prepared to support the project’s CEQA compliance. The project also requires discretionary approval from United States Army Corps of Engineers; therefore, the project is also evaluated in accordance with National Environmental Policy Act (NEPA).

As the project is located within the South Coast Air Basin, the appropriate CEQA and NEPA criteria are those for the SCAQMD. As discussed previously, the SCAQMD is the air pollution control agency responsible for protecting the people and the environment of the South Coast Air Basin from the effects of air pollution. Accordingly, the City evaluates project air quality emissions based on the quantitative emission thresholds originally established in the SCAQMD’s CEQA Air Quality Handbook (SCAQMD 1993). SCAQMD’s significance thresholds for impacts to regional air quality are shown in Table 4.

5.3 Localized Significance Thresholds
The SCAQMD’s Final Localized Significance Threshold (LST) Methodology was developed as a tool to assist lead agencies to analyze localized air quality impacts to sensitive receptors in the vicinity of the project (SCAQMD 2008). The LST Methodology outlines how to analyze localized impacts from common pollutants of concern including NO 2, CO, PM 10, and PM 2.5.

Localized air quality impacts would occur if pollutant concentrations at sensitive receptors exceeded applicable NAAQS or CAAQS.

LSTs represent the maximum emissions from a project that will not cause or contribute to an exceedance of the most stringent applicable federal or state ambient air quality standard at the nearest residence or sensitive receptor. The SCAQMD states that lead agencies can use the LSTs as another indicator of significance in its air quality impact analyses. The significance of localized emissions impacts depends on whether ambient levels in the vicinity of any given project are above or below State standards. In the case of CO and NO 2, if ambient
levels are below the standards, a project is considered to have a significant impact if project emissions result in an exceedance of one or more of these standards. If ambient levels already exceed a state or federal standard, then project emissions are considered significant if they increase ambient concentr ations by a measurable amount. This would apply to PM 10 and PM2.5, both of which are non-attainment pollutants.

6.0 Air Quality Calculations
Construction impacts are short term and result from fugitive dust, equipment exhaust, and indirect effects associated with construction workers and deliveries. Operational impacts can occur on two levels: regional or local. In the case of this project, operational impacts are primarily due to emissions from project -related mobile sources associated with vehicular travel along the roadways. Operational emissions also consist of area sources that are direct sources of emissions located at the project site.

Construction and operation air emissions were calculated using California Emissions Estimator Model (CalEEMod) 2016.3.2 (California Air Pollution Control Officers Association [CAPCOA] 2017). The CalEEMod program is a tool used to estimate air emissions resulting from land development projects based on California -specific emission factors. The model Air Quality Analysis
Sycamore Hills Distribution Project

Page 21 ends

estimates mass emissio ns from two basics sources: construction sources and operational sources (i.e., area, energy, and mobile sources).

Inputs to CalEEMod include such items as the air basin containing the project, land uses, trip generation rates, trip lengths, vehicle fleet mix (percentage of autos, medium truck, etc.), trip destination (i.e., percent of trips from home to work, etc.), duration of construction phases, construction equipment usage, grading areas, season, and ambient temperature, as well as other parameters. The CalEEMod output files contained in Attachment 1 indicate the specific outputs for each model run. Emissions of NOX, CO, SO2, PM10, PM2.5, and ROG are calculated. Emission factors are not available for lead, and consequently, lead emissions are not calculated. The South Coast Air Basin is currently in attainment of the federal and state lead standards. Furthermore, fuel used in construction equipment and most other vehicles is not leaded.

6.1 Construction Regional Emissions
Construction-related activities are temporary, short -term sources of emissions. Sources of construction-related emissions include:
• Fugitive dust from grading activities;
• Construction equipment exhaust; and
• Construction-related trips by workers, delivery trucks, and material-hauling trucks.

Construction-related emissions include emissions from dust raised during grading, exhaust from construction vehicles, and chemicals used during construction. Fugitive dust emissions vary greatly during construction and are dependent on the amount and type of activity, silt content of the soil, and the weather. Vehicles moving over paved and unpaved surfaces, excavation, earth movement, grading, and wind erosion from exposed surfaces are all sources of fugitive dust. Construction operations are subject to the requirements established by the SCAQMD including Rule 403, Fugitive Dust. Rule 403 requires the use of best available control measures for fugitive dust. This analysis assumes that standard dust and emission control during grading operations would be implemented to reduce potential nuisance impacts and to ensure compliance with SCAQMD Rule 403, which is estimated to result in a 61 55 percent reduction in fugitive dust from watering twice per day.

Heavy-duty construction equipment is usually diesel powered. Standard construction equipment includes dozers, rollers, scrapers, dewatering pumps, backhoes, loaders, paving equipment, delivery/haul trucks, jacking equipment, welding machines, pile drivers, and so on.

Specific construction phasing and equipment parameters are not available at this time.

However, CalEEMod can estimate the required construction equipment when project-specific information is unavailable. The estimates are based on surveys, performed by the SCAQMD and the Sacramento Metropolitan Air Quality Management District, of typical construction projects that provide a basis for scaling equipment needs and schedule with a project’s size. Air emission estimates in CalEEMod are based on the duration of construction phases; construction equipment type, quantity, and usage; grading area; season; and ambient temperature, among other parameters. The construction schedule is based on a reasonable approximation and information provided by the proje ct applicant. Based on project-specific information provided by the project applicant, C construction emissions were modeled assuming site preparation/grading would last three months, and the remaining construction Air Quality Analysis

activities (building, paving, landscaping, architectural coatings) would last approximately one year for a total construction duration of 15 months . During the grading phase, 40,000 cubic yards of soil quantities would be balanced on-site between the two building areas with no net import or export. Soil hauling between Parcel 1 and Parcel 2 could be done with the modeled grading equipment, which includes graders and scrapers capable of moving large quantities of soil. However, to be conservative and account for the usage of trucks to haul soil from one parcel to the other, 40,000 cubic yards of soil hauling has been added to the grading phase with a trip length of one mile.

Table 5 summarizes the anticipated construction phases, duration, and equipment for total project construction (Buildings A and B).

Table 7 shows the total projected (Buildings A and B) construction maximum daily emission levels for each criteria pollutant and compares emissions to the SCAQMD regional significance thresholds.

As shown in Table 6, total maximum annual construction e missions associated with all phases of construction of the project would be below the applicable annual General Conformity de minimis levels and would conform to the applicable SIP. No further analysis would be required and no adverse air quality impacts would occur.

As shown in Table 7, maximum daily construction emissions for each separate phase of construction of the project would be less than the daily SCAQMD regional thresholds for all criteria pollutants. Note that none of the construction phases would overlap.

6.2 Operational Regional Emissions
Mobile source emissions would originate from traffic generated by the project. Area source emissions would result from the use of natural gas, consumer products, as well as applying Air Quality Analysis

architectural coatings and landscaping activities. Based on the entitlements and construction schedule for the project, it is anticipated that the soonest operational year would be 2023; therefore, operational emissions were modeled for year 2023.

Mobile source operational emissions are based on the trip rate, trip length, and vehicle mix.

Total passenger vehicle and truck trip generation was obtained from the traffic report prepared for the project (Urban Crossroads 2019). The trip lengths for passenger vehicles and trucks were obtained from the trip length analysis prepared for the project (Urban Crossroads 2020).

By default, mobile emissions in CalEEMod are calculated using CARB’s 2014 Emission Factor model (EMFAC2014). The U.S. EPA recently approved the use of CARB’s 2017 Emission Factor model (EMFAC2017) . However, this had not yet been incorporated into CalEEMod, and there is no standardized approach to modifying the emission factors included in CalEEMod . Generally, vehicles have become cleaner over time; therefore, the mobile emissions would not be higher if CalEEMod were adjusted using EMFAC2017 emission factors. For the operational LST analysis discussed later in Section 6.3.2, the emission calculations for on-site truck activity were calculated using the newer EMFAC2017 emission factors.

The project-specific trip generation and trip length data is summarized in Table 8.

Mobile source operational emissions are also based on the project’s vehicle mix. Based on the traffic report prepared for the project, the project would generate 573 passenger car trips and 274 truck trips, of which 46 would be 2-axle trucks, 57 would be 3-axle trucks, and 171 would be 4-axle+ trucks (Urban Crossroads 2019). The CalEEMod non-heavy truck vehicle fleet mix includes the following categories: passenger cars (LDA), light-duty trucks (LDT1 and LDT2), medium-duty truc ks ( MDV), and motorcycles (MCY). The 573 passenger car trips were modeled by proportionally altering these values based on the CalEEMod default values. Note that CalEEMod also includes other non- truck vehicles such as buses and motor homes ; however, these vehicle classifications would not be associated with the project. For the truck mix, CalEEMod includes four truck categories: light- heavy-duty trucks (LHD1 and LHD2), medium-heavy-duty trucks (MHD), and heavy -heavy-duty trucks (HHD). The 2-axle trucks were modeled as LHD1, the 3 -axle trucks were modeled as LHD2, and the 4 -axle+ trucks were divided proportionally and modeled as MHD and HHD.

Area sources are direct sources of emissions located at the project site. Area source emissions associated with the project include consumer products, natural gas used in space and water heating, architectural coatings, and landscaping equipment. Hearths (fireplaces) and woodstoves are also a source of area emissions; however, the project would not include hearths or woods toves. Consumer products are chemically formulated products used by household and institutional consumers, including, but not limited to, detergents, cleaning compounds, polishes, floor finishes, disinfectants, sanitizers, and aerosol paints but not including other paint products, furniture coatings, or architectural coatings. Emissions due to consumer products are calculated using total building area and product emission factors.

Emissions are generated from the combustion of natural gas used in space and water heating.

Emissions are based on the Residential Appliance Saturation Survey , which is a comprehensive energy use assessment that includes the end use for various climate zones in California.

For architectural coatings, emissions result from evaporation of solvents contained in surface coatings such as in paints and primers. Emissions are based on the building and parking lot/asphalt surface area, architectural coating emission factors, and a reapplication rate of 10 percent of area per year. Note that for a worst -case architectural coating analysis, the Parcel C trailhead parking lot was modeled as a paved and striped parking lot to account for emissions from striping paint and pavement sealant. The Parcel C parking lot would be partially conc rete and partially decomposed granite that would be properly stabilized to reduce dust. To account for possible dust emissions that could result from vehicles parking at the trailhead parking lot, this analysis used U.S. EPA AP -42 emission factors and methodology (U.S. EPA 1998) to calculate PM10 and PM2.5 emissions for a gravel parking lot which generates more dust than a stabilized decomposed granite parking lot. Emissions were calculated assuming each parking space would be used and each vehicle would tr avel the entire length of the parking lot when entering and leaving. Calculations are provided in Attachment 1.

Landscaping maintenance includes fuel combustion emission from equipment such as lawn mowers, rototillers, shredders/grinders, blowers, trimmers, chain saws, and hedge trimmers as well as air compressors, generators, and pumps. Emission calculations take into account building area, equipment emission factors, and the number of days that landscaping equipment is likely to operate.

Table 9 provides a summary of the operational emissions generated by the project. CalEEMod output files for project operation are contained in Attachment 1. As shown, project-generated emissions are projected to be less than the SCAQMD’s significance thresholds for all criteria pollutants.

6.3 Localized Significance Thresholds

6.3.1 Construction Localized Significance Thresholds
Calculations
The project site is located within Riverside Source Receptor Area 23 . LSTs apply to on -site air emissions of CO, NO2, PM10, and PM2.5. Based on the SCAQMD’s Fact Sheet for Applying CalEEMod to Localized Significance Thresholds (Fact Sheet), the appropriate methodology for determining localized impacts that could occur as a result of project-related construction, should follow these steps:
• Use CalEEMod to determine the maximum daily on-site emissions that will occur during construction activity.
• The SCAQMD’s Fact Sheet is used to determine the maximum site acreage that is actively disturbed based on the construction equipment fleet and equipment hours as estimated in CalEEMod.

Air Quality Analysis
Sycamore Hills Distribution Project

Page 27 ends

• If the total calculated acreage is less than or equal to five acres, then the SCAQMD’s screening look-up tables may be utilized to determine the potential for significant impacts. The look-up tables establish a maximum daily emissions threshold in pounds per day to be directly compared to CalEEMod emission results. • If the total acreage disturbed is greater than five acres per day, then the SCAQMD recommends dispersion modeling to be conducted to determine the actual pollutant concentrations for applicable LSTs.

Additionally, the LST Methodology states that only on-site emissions should be compared to LSTs. Therefore, off-site emissions associated with worker travel, materials deliveries, and other mobiles sources are not evaluated against LSTs.

The maximum on-site daily emissions for CO, NOX, PM10, and PM2.5 for construction activity are compared to the applicable screening thresholds based on construction site acreage and the distance to the closest sensitive receptor, which is approximately 200 meters south of the development area. To determine the maximum daily disturbed acreage for use in the SCAQMD’s LST look-up tables, the maximum acres per day were developed from the CalEEMod Users Guide. Based on the CalEEMod Users Guide, the proposed project is anticipated to disturb approximately 5 acres per day during the rough grading phase of construction (Table 10). As such, the 5-acre screening table should be utilized to evaluate emissions against LSTs. The grading phase is used, as it uses the greatest amount of heavy construction equipment, which represents a conservative, i.e., “worst-case” analytical scenario for purposes of construction LSTs.

6.3.2 Operational Localized Significance Thresholds
Calculations
Once operational, on-site sources of emissions associated with the project would be passenger cars arriving at and departing from the facility, and trucks maneuvering on -site and idling at the proposed loading docks. The site plan identifies 49 loading docks on the east side of Building A, 39 loading docks on the west side of Building A, and 34 loading docks on the south side of Building B. The project would also includ e the operation of up to three non - diesel yard trucks used to move freight around the warehouse. For the operational LST analysis, on-site passenger car and truck travel and idling emissions were modeled in the AERMOD dispersion model using emission factors for CO, NO2, PM10, and PM2.5 generated by EMFAC2017. The EMFAC2017 model generates emission factors in terms of grams per vehicle activity and vehicle category. Each on-site idling and travel route was modeled as a line volume source in AERMOD assuming t hat vehicles would travel at 5 mph while maneuvering on site , and each truck would idle for 15 minutes. Although the p roject is required to comply with CARB’s idling limit of 5 minutes, staff at SCAQMD recommends that the on-site idling emissions should be estimated for 15 minutes of idling (SCAQMD 2009). As such, this analysis estimated truck idling at 15 minutes, consistent with SCAQMD’s recommendation. The yard trucks were also modeled as sources operating throughout the project site. Surface and upper air meteorological data from the Riverside Airport monitoring station was used in the AERMOD model.

The SCAQMD has established that impacts to air quality are significant if there is a potential to contribute or cause localized exceedances of the State AAQS. For CO and NO 2, the emissions contribution from the project is added to ambient concentrations and the total is then compared to the most stringent applicable state and/or federal ambient air quality standards. PM2.5 and PM10 impacts are treated differently than CO and NO2, since nearly the entire district exceeds the state or federal PM2.5 and PM10 standards. PM2.5 and PM10 impacts from operational activities are derived based on the allowable change in concentration thresholds. Because the entire district is nonattainment for PM

2.5 and PM10, determining
background concentrations for these pollutants is unnecessary.

Applicable localized thresholds are as follows (SCAQMD 2015b):
• California State 1-hour CO standard of 20.0 ppm;
• California State 8-hour CO standard of 9.0 ppm;
• California State 1-hour NO2 standard of 0.18 ppm;
• California State Annual NO2 standard of 0.03 ppm;
• SCAQMD 24-hour operational PM10 LST of 2.5 μg/m3;
• SCAQMD Annual operational PM10 LST of 1.0 μg/m3; and
• SCAQMD 24-hour operational PM2.5 LST of 2.5 μg/m3.

6.3.3 Carbon Monoxide Hot Spots
A CO hot spot is an area of localized CO pollution that is caused by severe vehicle congestion on major roadways, typically near intersections. CO hot spots have the potential to violate state and federal CO standards at intersections, even if the broader basin is in attainment for federal and state levels. The California Department of Transportation Project-Level Carbon Monoxide Protocol (CO Protocol; U.C. Davis Institute of Transportation Studies 1997) indicates that CO hot spots occur nearly exclusively at signalized intersections operating at level of service (LOS) E or F. Accordingly, the CO Protocol recommends detailed air quality dispersion modeling for projects that may worsen traffic flow at any signalized intersections operating at LOS E or F.

Due to increased requirements for cleaner vehicles, equipment, and fuels, CO levels in the state have dropped substantially. All air basins are attainment or maintenance areas for CO.

Therefore, more recent screening procedures based on more current methodologies have been developed. The SMAQMD developed a screening threshold in 2011, which states that any project involving an intersection experiencing 31,600 vehicles per hour or more will require detailed analysis. In addition, the Bay Area Air Quality Management District developed a screening threshold in 2010 which states that any project involving an intersection experiencing 4 4,000 vehicles per hour would require detailed analysis. This analysis conservatively assesses potential CO hot spots using the SMAQMD screening threshold of 31,600 vehicles per hour.

Based on the traffic report prepared for the project, in horizon year 2040 with the project, the following signalized intersections are anticipated to operate at LOS E or F:
• Sycamore Canyon Boulevard at Alessandro Boulevard (LOS F AM and PM) • Interstate 215 northbound ramps at Alessandro Boulevard (LOS E AM and PM) However, the traffic volumes at these intersections would be well less than 31,600 vehicles per hour. All other signalized intersections are projected to operate at LOS D or better.

Therefore, the project is not anticipated to result in a CO hot spot.

6.4 Impact Analysis

1. Would the project conflict with or obstruct implementation of the applicable air quality plan?
As stated previously, the South Coast Air Basin is designated as in attainment or unclassifiable attainment (expected to be meeting the standard despite a lack of monitoring data) for all federal air quality standards except for the 8 -hour ozone and PM 2.5 standards.

The South Coast Air Basin is also designated as in nonattainment for state air quality standards for 8 -hour ozone and PM 2.5, and addi tionally is in nonattainment of state PM 10 standards. The regional air quality plan, the 2016 AQMP, outlines measures to reduce emissions of ozone and PM2.5. Whereas reducing PM concentrations is achieved by reducing emissions of PM2.5 to the atmosphere, reducing ozone concentrations is achieved by reducing the precursors of photochemical formation of ozone, VOC, and NOX.

The growth forecasting for the AQMP is based in part on the land uses established by local general plans. Thus, if a project is consistent with land use as designated in the local general plan, it can normally be considered consistent with the AQMP. Projects that propose a different land use than is identified in the local general plan may also be considered consistent with the AQMP if the proposed land use is less intensive than buildout under the current designation. For projects that propose a land use that is more intensive than the current designation, analysis that is more detailed is required to assess conformance with the AQMP.

The project site is designated as Business/Office Park (B/OP) in the General Plan , and is zoned BMP-SP – Business and Manufacturing Park (BMP) and Specific Plan (Sycamore Canyon Business Park Specific Plan – Industrial) Overlay Zones. Permitted land uses include light industrial, distribution and warehousing, and product assembly. The project would be consistent with the land use and zoning designations. It would therefore be consistent with the growth assumptions of the 2016 AQMP.

Another factor used to determine if a project would conflict with implementation of the AQMP is determining if the project would 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 (NAAQS and CAAQS) or interim emissions reductions specified in the AQMP. NAAQS and CAAQS violations could occur if project emissions would exceed regional significance thresholds or LSTs. As shown in T ables 6 and 8, construction and operational emissions would be less than the regional significance thresholds.

Additionally, as shown in Tables 10 and 11, construction and operational emissions would be less than the LSTs. Therefore, the project would not result in an air quality violation. T he project would not conflict with or obstruct the implementation of the AQMP or applicable portions of the SIP.

Air Quality Analysis
Sycamore Hills Distribution Project

Page 31 ends

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 federal or state ambient air quality standard?
As discussed in Section 4.3, Existing Air Quality, the Basin is classified as in attainment for all criterion pollutants except for ozone, PM 10, and PM 2.5. The Basin is designated as a nonattainment area for federal AAQS for the 8- hour ozone and PM 2.5 standards, and is in nonattainment area under state PM10 standards. Ozone is not emitted directly, but is a result of atmospheric activity on precursors. NOX and ROG are known as the chief “precursors” of ozone. These compounds react in the presence of sunlight to produce ozone.

As shown in Tables 7 and 9, emissions of ozone precursors (ROG and NOX), PM10, and PM2.5 from construction and operation would be below the SCAQMD’s thresholds of significance.

These thresholds were developed based on the CAA de minimis level, which are designed to provide limits below which project emissions from an individual project would not significantly affect regional air quality or the timely attainment of the NAAQS and CAAQS.

Additionally, as shown in Tables 11 and 12, maximum localized construction and operational emissions would not ex ceed any of the SCAQMD recommended localized screening thresholds. Therefore, the project would not result in a cumulatively considerable net increase in emissions of ozone, PM
10, or PM2.5, and impacts would be less than significant.

3. Would the project expose sensitive receptors to substantial pollutant concentrations? A sensitive receptor is a person in the population who is more susceptible to health effects due to exposure to an air contaminant than is the population at large. Examples of sensitive receptor locations in the community include residences, schools, playgrounds, childcare centers, churches, athletic facilities, retirement homes, and long -term health care facilities.

The sensitive receptors nearest to the project site include single and multi-family residences to the south and southeast of the project s ite. The project was analyzed for it s potential to result in significant health risk impacts resulting from short -term construction and long - term operational emissions.

Results of the LST analysis indicate that the project would not exceed the SCAQMD LSTs during construction (see Table 11). Results of the LST analysis also indicate that the project would not exceed the SCAQMD LSTs during operational activity ( see Table 12). The LSTs represent the maximum emissions from a project that will not cause or contribute to an exceedance of the most stringent applicable NAAQS or CAAQS at the nearest residence or sensitive receptor. The SCAQMD states that lead agencies can use the LSTs as anothe r indicator of significance in its air quality impact analyses. LSTs were developed in response to environmental justice and health concerns raised by the public regarding exposure of individuals to criteria pollutants in local communities. To address the issue of localized significance, the SCAQMD adopted LSTs that show whether a project would cause or contribute to localized air quality impacts and thereby cause or contribute to potential localized adverse health effects. Because construction and operational activity would not result in an exceedance of the SCAQMD’s LSTs, sensitive receptors would not be exposed to substantial pollutant concentrations during project construction or operation, and, therefore, would not cause or contribute to potential localized adverse health effects.

Additionally, the project was evaluated for consistency with the Western Riverside Council of Governments (WRCOG) Good Neighbor Guidelines for Site New and/or Modified Warehouse/Distribution Facilities (Good Neighbor Guidelines; WRCOG 2005) as well as the City’s own Good Neighbor Guidelines for Siting New and/or Modified Warehouse Distribution Facilities (Good Neighbor Guidelines; City of Riverside 2008). Both Good Neighbor Guidelines were designed to help minimize the impacts of DPM from on-road trucks associated with warehouses and distribution centers on existing communities and sensitive receptors located in the region. The City’s Good Neighbor Guidelines are similar to the WRCOG Guidelines, with the City’s being tailored to the City’s unique characteristics and specific needs. These guidelines include the following goals that can be implemented at the regional level:
• Minimize exposur e to diesel emissions to neighbors that are s ituated in close proximity to the warehouse/distribution center;
o Recommended strategy: Design facilities to allow for the queuing of truck on -site and away from sensitive receptors. Conversely, prevent the queuing of trucks on streets or elsewhere outside of facility in compliance with Title 10 – Vehicles and Traffic – Chapter 10.44 – Stopping, Standing and Parking.

Project consistency: Based on the project location and design, no truck queuing would occur next to sensitive receptors, which are located sout h of Alessandro Boulevard. Truck queuing would not occur outside the facility. o Recommended strategy: To the extent possible, locate driveways, loading docks and internal circulation route away from residential uses or any other sensitive receptors.

Project consistency: Driveways, loading docks, and internal circulation routes are not adjacent to sensitive receptors. Further, as calculated in this analysis, emissions due to on -site operations would not expose sensitive receptors to substantial pollutant concentrations.
o Recommended strategy: Conduct SCAQMD URBEMIS and EMFAC computer models as appropriate, to initially evaluate warehouse and distribution projects on a case by case basis to determine the significance of air quality impacts and whether air quality thresholds would be exceeded as a result of the project. Where thresholds are exceeded, a more detailed air quality specialist is required to be prepared and submitted by the project applicant.

Project consistency: As calculated and concluded in this analysis, the project would not result in significant air quality impacts.
o Recommended strategy: Enforce compliance with Riverside Municipal Code Section 19.880 – “Transportation Demand Management Regulations”. This section of the Code requires trip reduction plans to be submitted for all businesses, including warehouses, with over one hundred employees to reduce work -related vehicles trips by six and one half percent from the number of trips related to the project.

Air Quality Analysis
Sycamore Hills Distribution Project

Page 33 ends

Project consistency: The project would include transportation demand management measures that would reduce emissions assoc iated with employee trips. These include access to public transit (Routes 20 and 208), bicycle parking, clean air/van pool parking spaces, and electric vehicle parking. • Eliminate diesel trucks from unnecessarily traversing through residential neighborhoods;
o Recommended strategy: Require warehouse/distribution centers to establish a specific truck route between the warehouse/distribution center and the State Route 60 and I nterstate 215 freeways for City approval as part of the Design Review process. In addit ion, a haul route plan for construction activities should also be provided as part of the Design Review process.

Project consistency: The project site is located one mile west of Interstate 215, with direct access via Alessandro Boulevard which is an existing truck route. o Recommended strategy: Require warehouse/distribution centers to clearly specify all entrance and exit points on the site plan submitted for City review and approval.

Project consistency: The project site plans indicate all entrance and exit points. o Recommended strategy: Require warehouse/distribution centers to provide on-site signage for directional guidance to trucks entering and exiting the facility.

Project consistency: On-site signage for directional guidance will be provided. o Recommended strategy: Require warehouse/distribution centers to provide signage or flyers that advise truck drivers of the closest restaurants, fueling stations, truck repair facilities, lodging and entertainment.

Project consistency: The future tenants are un known at this time ; however, this information is readily available to truck drivers.
• Eliminate trucks from using residential areas and repairing vehicles on the streets; o Recommended strategy: Enforce compliance with Riverside Municipal Code Section 10.44.155 – “Parking of certain commercial vehicles, trailers and semi - trailers prohibited; exceptions”, Section 10.44.160 – “Parking of certain commercial vehicles prohibited in residential districts” and Section 10.44.040 “Parking for certain purposes prohibited”.

Project consistency: The project would comply with all Municipal Code requirements. No trucks would be parked off-site.
• Reduce and/or eliminate diesel idling within the warehouse/distribution center; o Recommended strategy: Promote the installation of on -site electric hook -ups to eliminate the idling of main and auxiliary engines during loading and unloading of cargo and when trucks are not in use – especially where Tran sportation Refrigeration Units are proposed to be used.

Project consistency: The project would not include Transportation Refrigeration Units. All trucks would be required to comply with the CARB idling limit of 5 minutes.
o Recommended strategy: Implement G eneral Plan 2025 Program Final Program Environmental Impact Report, Mitigation Measure MM Air 12. This Mitigation Measure requires that all new truck terminals, warehouses and other shipping facilities requiring the use of refrigerated trucks and with more than 50 truck trips per day shall provide electrical hookups for the refrigerated units to reduce idling and its associated air quality pollutants. Additionally, future tenant improvements involving conversion of a warehouse for refrigeration storage shall include electrical hookups for refrigerated units.

Project consistency: The project would not include Transportation Refrigeration Units or refrigeration storage.
o Recommended strategy: Require signage (posted inside and outside of the warehouse facility) to inform truck drivers of CARB regulations, idling limits, authorized truck route, and designated truck parking locations. Post signs requesting truck drivers to turn off engines when not in use and restrict idling within facilities to less than 5 minutes.

Project consistency: The project would include signage regarding idling limits, truck routes, and parking.

Additionally, the City’s Guidelines recommend the enforcement of the Riverside Municipal Code.

The City is currently in the process of updating the Riverside Good Neighbor Guidelines. The updated guidelines include new limits of operations and require on -site electrical loading dock hook ups. The updated Good Neighbor Guidelines have not yet been adopted, but as proposed at the time of this report, the project would be in compliance with the proposed updates.

4. Would the project result in other emissions (such as those leading to odors) adverse ly affecting a substantial number of people?
During construction, diesel equipment may generate some nuisance odors. Sensitive receptors near the project site include residential uses approximately 300 feet south of the project site; however, exposure to odors associated with project construction would be short term and temporary in nature. It should also be noted that all construction equipment is subject to the CARB In-Use Off-Road Diesel-Fueled Fleets Regulation. This regulation, which applies to all off-road diesel vehicles 25 horsepower or greater, limits unnecessary idling to 5 minutes, requires all construction fleets to be labeled and reported to CARB, bans Tier 0 equipment and phases out Tier 1 and 2 equipment (thereby replacing fleets with cleaner equipment), and requires that fleets comply with Best Available Control Technology requirements. Implementation of this measure reduces construction exhaust emissions, thereby also reducing construction equipment odors. Additionally, SCAQMD Rule 402 addresses nuisance emissions, including odors. Rule 402 states “A person shall not discharge Air Quality Analysis
Sycamore Hills Distribution Project

Page 35 ends

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.” Due to the distance to the residential receptor s, implementation of CARB regulations, the short-term nature of construction, and enforcement of Rule 402, construction odor impacts would be less than significant.

The following list provides some common types of facilities that are known producers of objectionable odors (Bay Area Air Quality Management District 2010). This list of facilities is not meant to be all-inclusive.
• Wastewater Treatment Plant
• Wastewater Pumping Facilities
• Sanitary Landfill
• Transfer Station
• Composting Facility
• Petroleum Refinery
• Asphalt Batch Plant
• Chemical Manufacturing
• Fiberglass Manufacturing
• Painting/Coating Operations
• Rendering Plant
• Coffee Roaster
• Food Processing Facility
• Confined Animal Facility/Feed Lot/Dairy
• Green Waste and Recycling Operations
• Metal Smelting Plants

The project does not include any of these uses that are typically associated with odor complaints. The project does not propose any uses or activities that would result in potentially significant operational-source odor impacts. The project proposes the operation of a high-cube warehouse, which is not included on CARB’s list of facilities that are known to be prone to generate odors. During operation of the project, odors could also be emitted from trucks maneuvering on -site and idling at the proposed loading docks. However, all trucks would be required to comply with CARB’ s idling limit of 5 minutes, and these trucks would not produce a significant amount of odors. Consistent with City requirements, all project - generated refuse would be stored in covered containers and removed at regular intervals in compliance with solid waste regulations, thereby precluding substantial generation of odors due to temporary holding of refuse on-site. The project is not expected to generate significant objectionable odors affecting a substantial number of people. Impacts would be less than significant.

7.0 Conclusions
The project’s potential to result in impacts to air quality was assessed in accordance with the guidelines, policies, and standards established by the City and the SCAQMD. The SCAQMD prepared the 2016 AQMP, which represents its contribution to the SIP, to outline the district’s strategy for achieving attainment of fede ral and state AAQS. The 2016 AQMP provides an overview of air quality and sources of air pollution, and identifies the pollution - control measures needed to meet clean air standards. The project would be consistent with the land use and zoning designations and would support the development goals of the Sycamore Canyon Business Park Specific Plan. The project would also be consistent with the growth assumptions of the 2016 AQMP. Additionally, the project would not result in an air quality violation. Therefore, the project would not conflict with or obstruct the implementation of the 2016 AQMP or applicable portions of the SIP.

Implementation of the project would result in air quality emissions associated with the construction and operation of the project. As shown in Tables 7 and 9, project construction and operation would not exceed the SCAQMD’s thresholds of significance. Therefore, as project operation emissions would be below these limits, project operation would not result in regional emissions that would exceed the NAAQS or CAAQS or contribute to existing violations. Therefore, the project would result in a less than significant impact.

As shown in Table s 11 and 12, project construction and operational emissions would not exceed the SCAQMD’s LSTs. Thu s, the project would not result in localized emissions that exceed the NAAQS or CAAQS or expose nearby sensitive receptors to unhealthy pollutant concentrations. The project would result in a less than significant local air quality impact.

The potential for an odor impact is dependent on a number of variables including the nature of the odor source, distance between the receptor and odor source, and local meteorological conditions. During construction, potential odor sources associated with the project include diesel exhaust associated with construction equipment. Diesel exhaust may be noticeable; however, construction activities would be temporary, and would dissipate without affecting a substantial number of people. The project does not include a use that is anticipated to generate substantial odors. Impacts would be less than significant.
