Subject: Alta Fontana Mixed Use Project – Air Quality Technical Memorandum
PURPOSE
The purpose of this technical memorandum is to evaluate potential short- and long-term air quality
impacts that would result from the construction and operation of the proposed Alta Fontana Mixed Use
Project (project), located in the City of Fontana (City), California.
PROJECT LOCATION
The project site is located at 14817 Foothill Boulevard and is bound by Foothill Boulevard to the north,
Live Oak Avenue to the east, single-family residences to the south, and a shopping plaza and multi-family
residences to the west. Regional access to the site is available via Interstate 15 (I-15) at the Foothill
Boulevard exit, approximately three miles west of the project site. Local access to the site is provided via
Foothill Boulevard and Live Oak Avenue. The project site comprises two parcels (Assessor’s Parcel
Numbers [APN] 0230-071-03 and 0230-071-04).
EXISTING SITE CONDITIONS
The project site is approximately 8.8 acres (9.5 gross acres with road improvements and sidewalks) and
currently consist of undeveloped vacant land. Grasses and weeds cover much of the project site. No
existing structures are present on-site; however, an area in the northeastern portion of the project site
contains a slab foundation of a former structure. The project site topography is generally flat with a slight
regional slope to the southwest. The project site is located in the northern portion of the Upper Santa Ana
Valley, which is a broad downwarped (i.e., downward and depressed) area encompassing approximately
50 miles, at an elevation of approximately 1,240 to 1,245 feet, an approximate elevation difference of 5
feet. Overhead electrical lines are present at the north-central portion of the site.

The project site is designated Multi-Family High Residential (R-MFH) by the City of Fontana General Plan
Land Use Map.1 The project site is zoned Multi-Family High Density Residential (R5) by the City of Fontana
Zoning District Map.2
PROJECT DESCRIPTION
The project proposes development of a mixed-use residential apartment complex with 340 multi-family
units, 1,500 square feet of commercial space, and four live-work units. The mixed-use residential
apartment complex would consist of two four-story buildings. The 340 multi-family apartment units would
be either 1, 2, or 3 bedrooms, ranging in size from 726 square feet to 1,388 square feet. The four live-
work units would each be approximately 1,492 square feet. Additionally, the project would include the
construction of 529 surface parking spaces, including 9 commercial parking spaces, located in the western,
central, and southern portions of the project site.
The project would also include approximately 5,600-square-foot indoor amenity space, comprised of a
1,800-square-foot lobby/leasing office, a 1,375-square-foot fitness center, a 1,700-square-foot clubroom,
and a 720-square-foot business center in the northern building. The northern building would have two
landscaped courtyards, with one containing a pool and spa, and the southern building would have three
landscaped courtyards. The courtyards would contain a barbecue facility equipped with a grill and picnic
benches and children’s tot lot with play equipment.
Construction of the proposed project is anticipated to begin in December 2022 and would take
approximately 26 months to complete, concluding in January 2025. Construction activities would occur
from 7:00 a.m. to 6:00 p.m. Monday through Friday and 8:00 a.m. to 5:00 p.m. on Saturday, except for
purposes of emergencies. The construction period would include demolition, excavation, grading,
trenching, installation of utilities, building construction, architectural coating, paving activities, and
installation of landscaping and hardscape elements.
Criteria Air Pollutants
Air quality is a general description of how levels of air pollution and other atmospheric conditions can
affect public health and the environment. Under the Federal Clean Air Act, the U.S. Environmental
Protection Agency (EPA) has identified six air pollutants that are environmentally prevalent and produced
by human activities to be of concern with respect to health, the environment and welfare of the public.
These specific pollutants, known as criteria air pollutants, are pollutants for which the federal and state
governments have established ambient air quality standards—or criteria—for outdoor concentrations to
protect public health. These pollutants are common byproducts of human activities and have been
documented through scientific research to cause various adverse health effect outcomes. The federal
ambient concentration criteria are known as the National Ambient Air Quality Standards (NAAQS), and
the California ambient concentration criteria are referred to as the California Ambient Air Quality
Standards (CAAQS). The criteria air pollutants regulated at the federal jurisdiction include carbon
monoxide (CO), ground-level ozone (O3), nitrogen dioxide (NO2), respirable particulate matter ten microns
or less in diameter (PM10), fine particulate matter 2.5 microns or less in diameter (PM2.5), sulfur dioxide
(SO2), and lead (Pb).

Air Quality Technical Memorandum 3
Carbon Monoxide (CO). CO is an odorless, colorless toxic gas that is emitted by mobile and stationary
sources as a result of incomplete combustion of hydrocarbons or other carbon-based fuels. In cities,
automobile exhaust can cause as much as 95 percent of all CO emissions. CO replaces oxygen in the body’s
red blood cells. Individuals with a deficient blood supply to the heart, patients with diseases involving
heart and blood vessels, fetuses (unborn babies), and patients with chronic hypoxemia (oxygen deficiency)
as seen in high altitudes are most susceptible to the adverse effects of CO exposure. People with heart
disease are also more susceptible to developing chest pains when exposed to low levels of CO.
Ozone (O3). O3 occurs in two layers of the atmosphere. The layer surrounding the earth’s surface is the
troposphere. The troposphere extends approximately 10 miles above ground level, where it meets the
second layer, the stratosphere. The stratospheric (the “good” O3 layer) extends upward from about 10 to
30 miles and protects life on earth from the sun’s harmful ultraviolet rays. “Bad” O3 is a photochemical
pollutant, and needs volatile organic compounds (VOCs), nitrogen oxides (NOX), and sunlight to form;
therefore, VOCs and NOX are O3 precursors. To reduce O3 concentrations, it is necessary to control the
emissions of these O3 precursors. Significant O3 formation generally requires an adequate amount of
precursors in the atmosphere and a period of several hours in a stable atmosphere with strong sunlight.
High O3 concentrations can form over large regions when emissions from motor vehicles and stationary
sources are carried hundreds of miles from their origins.
While O3 in the upper atmosphere (stratosphere) protects the earth from harmful ultraviolet radiation,
high concentrations of ground-level O3 (in the troposphere) can adversely affect the human respiratory
system and other tissues. O3 is a strong irritant that can constrict the airways, forcing the respiratory
system to work hard to deliver oxygen. Individuals exercising outdoors, children, and people with pre-
existing lung disease such as asthma and chronic pulmonary lung disease are considered to be the most
susceptible to the health effects of O3. Short-term exposure (lasting for a few hours) to O3 at elevated
levels can result in aggravated respiratory diseases such as emphysema, bronchitis and asthma, shortness
of breath, increased susceptibility to infections, inflammation of the lung tissue, increased fatigue, as well
as chest pain, dry throat, headache, and nausea.
Nitrogen Dioxide (NO2). NOX are a family of highly reactive gases that are a primary precursor to the
formation of ground-level O3 and react in the atmosphere to form acid rain. NO2 (often used
interchangeably with NOX) is a reddish-brown gas that can cause breathing difficulties at elevated levels.
Peak readings of NO2 occur in areas that have a high concentration of combustion sources (e.g., motor
vehicle engines, power plants, refineries, and other industrial operations). NO2 can irritate and damage
the lungs and lower resistance to respiratory infections such as influenza. The health effects of short-term
exposure are still unclear. However, continued or frequent exposure to NO2 concentrations that are
typically much higher than those normally found in the ambient air may increase acute respiratory
illnesses in children and increase the incidence of chronic bronchitis and lung irritation. Chronic exposure
to NO2 may aggravate eyes and mucus membranes and cause pulmonary dysfunction.
Coarse Particulate Matter (PM10). PM10 refers to suspended particulate matter, which is smaller than 10
microns or ten one-millionths of a meter. PM10 arises from sources such as road dust, diesel soot,
combustion products, construction operations, and dust storms. PM10 scatters light and significantly
reduces visibility. In addition, these particulates penetrate lungs and can potentially damage the
respiratory tract. On June 19, 2003, the California Air Resources Board (CARB) adopted amendments to
the statewide 24-hour particulate matter standards based upon requirements set forth in the Children’s
Environmental Health Protection Act (Senate Bill 25).
Alta Fontana Mixed Use Project
Air Quality Technical Memorandum 4
Fine Particulate Matter (PM2.5). Due to recent increased concerns over health impacts related to fine
particulate matter (particulate matter 2.5 microns in diameter or less), both State and Federal PM2.5
standards have been created. Particulate matter impacts primarily affect infants, children, the elderly,
and those with pre-existing cardiopulmonary disease. In 1997, the U.S. Environmental Protection Agency
(EPA) announced new PM2.5 standards. Industry groups challenged the new standard in court and the
implementation of the standard was blocked. However, upon appeal by the EPA, the United States
Supreme Court reversed this decision and upheld the EPA’s new standards.
On January 5, 2005, the EPA published a Final Rule in the Federal Register that designated the Basin as a
nonattainment area for Federal PM2.5 standards. On June 20, 2002, CARB adopted amendments for
statewide annual ambient particulate matter air quality standards. These standards were
revised/established due to increasing concerns by CARB that previous standards were inadequate, as
almost everyone in California is exposed to levels at or above the current State standards during some
parts of the year, and the statewide potential for significant health impacts associated with particulate
matter exposure was determined to be large and wide-ranging. On July 8, 2016, EPA made a finding that
the Basin has attained the 1997 24-hour and annual PM2.5 standards based on 2011-2013 data. However,
the Basin remains in nonattainment as the EPA has not determined that California has met the Federal
Clean Air Act requirements for redesignating the Basin nonattainment area to attainment.
Sulfur Dioxide (SO2). Sulfur dioxide (SO2) is a colorless, irritating gas with a rotten egg smell; it is formed
primarily by the combustion of sulfur-containing fossil fuels. SO2 is often used interchangeably with sulfur
oxides (SOX). Exposure of a few minutes to low levels of SO2 can result in airway constriction in some
asthmatics.
Volatile Organic Compounds (VOC). VOCs are hydrocarbon compounds (any compound containing various
combinations of hydrogen and carbon atoms) that exist in the ambient air. VOCs contribute to the
formation of smog through atmospheric photochemical reactions and/or may be toxic. Compounds of
carbon (also known as organic compounds) have different levels of reactivity; that is, they do not react at
the same speed or do not form O3 to the same extent when exposed to photochemical processes. VOCs
often have an odor, and some examples include gasoline, alcohol, and the solvents used in paints.
Exceptions to the VOC designation include: carbon monoxide, carbon dioxide, carbonic acid, metallic
carbides or carbonates, and ammonium carbonate. The terms VOC and reactive organic gases (ROG) (see
below) are often used interchangeably.
Reactive Organic Gases (ROG). Similar to VOCs, ROGs are also precursors in forming O3 and consist of
compounds containing methane, ethane, propane, butane, and longer chain hydrocarbons, which are
typically the result of some type of combustion/decomposition process. Smog is formed when ROG and
NOX react in the presence of sunlight. ROGs are a criteria pollutant since they are a precursor to O3, which
is a criteria pollutant. The terms ROG and VOC are often used interchangeably.
EXISITNG SETTING
Regional Topography
The State of California is divided geographically into 15 air basins. The project site is located within the
South Coast Air Basin (Basin), a 6,600-square mile area bounded by the Pacific Ocean to the west and the
San Gabriel, San Bernardino, and the San Jacinto Mountains to the north and east. The Basin includes all
of Orange County and the non-desert portions of Los Angeles, Riverside, and San Bernardino Counties, in
Alta Fontana Mixed Use Project
Air Quality Technical Memorandum 5
addition to the San Gorgonio Pass area of Riverside County.
The extent and severity of the air pollution problem in the Basin is a function of the area's natural physical
characteristics (weather and topography), as well as man-made influences (development patterns and
lifestyle). Factors such as wind, sunlight, temperature, humidity, rainfall, and topography all affect the
accumulation and dispersion of air pollutants throughout the Basin.
Climate
The general region lies in the semi-permanent high-pressure zone of the eastern Pacific. As a result, the
climate is mild, tempered by cool sea breezes. The climate consists of a semi-arid environment with mild
winters, warm summers, moderate temperatures, and comfortable humidity. Precipitation is limited to a
few winter storms. The usually mild climatological pattern is interrupted infrequently by periods of
extremely hot weather, winter storms, or Santa Ana winds.
The average annual temperature varies little throughout the Basin, averaging 75 degrees Fahrenheit (°F).
However, with a less-pronounced oceanic influence, the eastern inland portions of the Basin show greater
variability in annual minimum and maximum temperatures. All portions of the Basin have had recorded
temperatures over 100°F in recent years.
Although the Basin has a semi-arid climate, the air near the surface is moist due to the presence of a
shallow marine layer. Except for infrequent periods when dry, continental air is brought into the Basin by
offshore winds, the ocean effect is dominant. Periods with heavy fog are frequent, and low stratus clouds,
occasionally referred to as "high fog," are a characteristic climate feature. The annual average relative
humidity is 70 percent at the coast and 57 percent in the eastern part of the Basin. Precipitation in the
Basin is typically nine to 14 inches annually and is rarely in the form of snow or hail due to typically warm
weather. The frequency and amount of rainfall are greater in the coastal areas of the Basin.
The height of the inversion is important in determining pollutant concentration. When the inversion is
approximately 2,500 feet above sea level, the sea breezes carry the pollutants inland to escape over the
mountain slopes or through the passes. At a height of 1,200 feet, the terrain prevents the pollutants from
entering the upper atmosphere, resulting in a settlement in the foothill communities. Below 1,200 feet,
the inversion puts a tight lid on pollutants, concentrating them in a shallow layer over the entire coastal
Basin. Usually, inversions are lower before sunrise than during the day. Mixing heights for inversions are
lower in the summer and more persistent, being partly responsible for the high levels of ozone (O3)
observed during the summer months in the Basin. Smog in southern California is generally the result of
these temperature inversions combining with coastal day winds and local mountains to contain the
pollutants for long periods of time, allowing them to form secondary pollutants by reacting with sunlight.
The Basin has a limited ability to disperse these pollutants due to typically low wind speeds.
Local Ambient Air Quality
CARB monitors ambient air quality at approximately 250 air monitoring stations across the State. Air
quality monitoring stations usually measure pollutant concentrations ten feet above ground level;
therefore, air quality is often referred to in terms of ground-level concentrations. The project site is
located within Source Receptor Area (SRA) 34, West San Bernardino Valley. The closest air monitoring
station to the project site is the Fontana-Arrow Highway Monitoring Station, located at 14360 Arrow
Boulevard, Fontana, approximately 0.7 miles southwest of the project site. Local air quality data from

Sensitive Receptors
Sensitive receptors are defined as facilities or land uses that include members of the population that are
particularly sensitive to the effects of air pollutants, such as children, the elderly, and people with illnesses.
Examples of these sensitive receptors are residences, schools, hospitals, and daycare centers. The nearby
sensitive receptors to the project site are residential communities located to the east, west, and south.

REGULATORY SETTING
Federal
Federal Clean Air Act
The FCAA of 1970 and the FCAA Amendments of 1971 required the EPA to establish National Ambient Air
Quality Standards (NAAQS), which required the EPA to adopt more stringent air quality standards or to
include standards for other specific pollutants. The FCAA was amended in 1990 to address a large number
of air pollutants that are known to cause or may reasonably be anticipated to cause adverse effects to
human health or adverse environmental effects. A total of 188 specific pollutants and chemical groups
were initially identified as HAPs, and the list has been modified over time. The FCAA Amendments
included new regulatory programs to control acid deposition and regulate the issuance of stationary
source operating permits. These standards identify levels of air quality for “criteria” pollutants that are
considered the maximum levels of ambient (background) air pollutants considered safe, with an adequate
margin of safety, to protect the public health and welfare; refer to Table 2, National and California
Ambient Air Quality Standards.
State
California Clean Air Act
Clean Air Act permitting in California is the shared responsibility of the CARB, its 35 air pollution control
agencies (districts), and EPA Region 9. Generally, CARB plays an oversight role for permitting and does not
issue any pre-construction or operating permits. However, the state agency provides significant support
to agencies that need permitting assistance.
California Air Resource Board
CARB administers the air quality policy in California. The California Ambient Air Quality Standards were
established in 1969 pursuant to the Mulford-Carrell Act. These standards, shown with the NAAQS in Table
2, are generally more stringent and apply to more pollutants than the NAAQS. In addition to the criteria
pollutants, CAAQS have been established for visibility reducing particulates, hydrogen sulfide, and
sulfates. The California Clean Air Act (CCAA), which was approved in 1988, requires that each local air
district prepare and maintain an Air Quality Management Plan (AQMP) to achieve compliance with the
CAAQS. These AQMP’s also serve as the basis for the preparation of the State Implementation Plan for
the State of California.
Like the EPA, CARB also designates areas within California as either attainment or non-attainment for each
criteria pollutant based on whether the CAAQS have been achieved. Under the CCAA, areas are designated
as non-attainment for a pollutant if air quality data show that a state standard for the pollutant was
violated at least once during the previous three calendar years. Exceedances that are affected by highly
irregular or infrequent events are not considered violations of a state standard and are not used as a basis
for designating areas as non-attainment.

1. California standards for ozone, carbon monoxide (except 8-hour Lake Tahoe), sulfur dioxide (1- and 24-hour), nitrogen dioxide, and 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 than 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 PM10, 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. 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. National Primary Standards: The levels of air quality necessary, with an adequate margin of safety, to protect the public health.
5. 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 1-hour standard is in units of parts per billion (ppb). California standards are in units of parts per million (ppm). To directly compare the national 1-hour standard 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. 6. 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 parts per million (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. 7. CARB 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 implementation of control measures
at levels below the ambient concentrations specified for these pollutants. 8. 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.
9. In 1989, CARB converted both the general statewide 10-mile visibility standard and the 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.

Regional
South Coast Air Quality Management District
Air Quality Thresholds
The project site is within the jurisdiction of South Coast Air Quality Management District. Under the
California Environmental Quality Act (CEQA), the SCAQMD is an expert commenting agency on air quality
within its jurisdiction or impacting its jurisdiction. Under the Federal Clean Air Act, the SCAQMD has
adopted Federal attainment plans for O3 and PM10. The SCAQMD provides guidance to lead agencies on
how to evaluate project air quality impacts related to the following criteria: (1) cause or contribute to any
new violation of any air quality standard; (2) increase the frequency or severity of any existing violation
of any air quality standard; or (3) delay timely attainment of any air quality standard or any required
interim emission reductions or other milestones of any Federal attainment plan.
The SCAQMD’s CEQA Air Quality Handbook also provides significance thresholds for both construction
and operation of projects within the SCAQMD jurisdictional boundaries. If the SCAQMD thresholds are
exceeded, a potentially significant impact could result. However, ultimately the lead agency determines
the thresholds of significance for impacts. If a project generates emissions in excess of the established
mass daily emissions thresholds, as outlined in Table 3, South Coast Air Quality Management District Mass
Daily Emissions Thresholds, a significant air quality impact may occur and additional analysis is warranted
to fully assess the significance of impacts. In addition, SCAQMD establishes odor threshold, which
identifies that project creating an odor nuisance pursuant to SCAQMD Rule 402 would cause a significant
impact.

Localized Significance Thresholds
Localized Significance Thresholds (LSTs) were developed in response to SCAQMD Governing Boards’
Environmental Justice Enhancement Initiative (I-4). The SCAQMD provided the Final Localized Significance
Threshold Methodology (dated July 2008) for guidance. The LST methodology assists lead agencies in
analyzing localized impacts associated with project-specific level proposed projects. LSTs represent the
maximum emissions from a project that are not expected to cause or contribute to an exceedance of the
most stringent applicable Federal or State ambient air quality standard and are developed based on the
ambient concentrations of that pollutant for each source receptor area and the distance to the nearest
sensitive receptor. The SCAQMD provides the LST lookup tables for one-, two-, and five-acre projects
Alta Fontana Mixed Use Project
Air Quality Technical Memorandum 10
emitting CO, NOX, PM10, or PM2.5. The LST methodology and associated mass rates are not designed to
evaluate localized impacts from mobile sources traveling over the roadways.
Cumulative Emissions Thresholds
The SCAQMD’s 2016 Air Quality Management Plan (2016 AQMP) was prepared to accommodate growth,
meet State and Federal air quality standards, and minimize the fiscal impact that pollution control
measures have on the local economy. According to the SCAQMD CEQA Air Quality Handbook, project-
related emissions that fall below the established construction and operational thresholds should be
considered less than significant unless there is pertinent information to the contrary. If a project exceeds
these emission thresholds, the SCAQMD CEQA Air Quality Handbook states that the significance of a
project’s contribution to cumulative impacts should be determined based on whether the rate of growth
in average daily trips exceeds the rate of growth in population.
Local
City of Fontana General Plan Update 2015-2035
A General Plan is a guiding document that provides residents, elected officials, business owners, and other
stakeholders with direction on how to meet the needs of a growing city and provides a greater quality of
life for its current and future residents. The City adopted the General Plan Update 2015-2035 (General
Plan Update) on November 13, 2018. Chapter 6, Building a Healthier Fontana, of the General Plan Update
identifies goals and policies to that will result in a healthier city. The following goal and policy focusing on
improving air quality are applicable to the proposed project:
Chapter 6, Building a Healthier Fontana
Goal 6.1: The average lifespan in Fontana consistently ranks within the top ten of all
Southern California cities.
Policy 6.1.3 Support local and regional initiatives to improve air quality in order to reduce
asthma while actively discouraging development that may exacerbate asthma
rates.
CALIFORNIA ENVIRONMENTAL QUALITY ACT THRESHOLDS
In accordance with the CEQA Guidelines, project impacts are evaluated to determine whether significant
adverse environmental impacts would occur. This analysis will focus on the project’s potential impacts and
provide mitigation measures, if required, to reduce or avoid any potentially significant impacts that are
identified. According to Appendix G of the CEQA Guidelines, the proposed project would have a significant
impact related to air quality, if it would:
• Conflict with or obstruct implementation of the applicable air quality plan (refer to Impact
Statement AQ-1);
• Result in a cumulatively considerable net increase of any criteria pollutant for which the project
region is in non-attainment under an applicable Federal or State ambient air quality standard
(refer to Impact Statement AQ-2);
Alta Fontana Mixed Use Project
Air Quality Technical Memorandum 11
• Expose sensitive receptors to substantial pollutant concentrations (refer to Impact Statement AQ-
3); and/or
• Result in other emissions (such as those leading to odors) adversely affecting a substantial number
of people (refer to Impact Statement AQ-4).
IMPACT ANALYSIS
AQ-1 WOULD THE PROJECT CONFLICT WITH OR OBSTRUCT IMPLEMENTATION OF THE
APPLICABLE AIR QUALITY PLAN?
As detailed above, the project site is located within the South Coast Air Basin where the SCAQMD has
jurisdiction. SCAQMD has a history of recorded air quality violations with both State and Federal ambient
air quality standards exceeded at times. 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 SCAQMD is required, pursuant to the Federal Clean Air Act, to reduce emissions of the air pollutants
for which the Basin is in nonattainment.
In order to reduce emissions, the SCAQMD adopted the 2016 AQMP, which establishes a program of rules
and regulations directed at reducing air pollutant emissions and achieving State and Federal air quality
standards. The 2016 AQMP is a regional and multi-agency effort including the SCAQMD, CARB, the
Southern California Association of Governments (SCAG), and the EPA.
The 2016 AQMP pollutant control strategies are based on the latest scientific and technical information
and planning assumptions, including the 2016-2040 Regional Transportation Plan/Sustainable
Communities Strategy (2016-2040 RTP/SCS), updated emission inventory methodologies for various
source categories, and SCAG’s latest growth forecasts. SCAG’s latest growth forecasts were defined in
consultation with local governments and with reference to local general plans. The SCAQMD considers
projects that are consistent with the AQMP, which is intended to bring the Basin into attainment for all
criteria pollutants, to also have less than significant cumulative impacts. While SCAG has recently adopted
the 2020-2045 Regional Transportation Plan/Sustainable Communities Strategy (2020-2045 RTP/SCS),
SCAQMD has not released an updated AQMP that utilizes information from the 2020-2045 RTP/SCS. The
updated AQMP is planned to be released in 2022. As such, this consistency analysis is based off the 2016
AQMP and 2016-2040 RTP/SCS.
Criteria for determining consistency with the 2016 AQMP are defined by the following indicators:
• Whether the proposed project would result in an increase in the frequency or severity of existing
air quality violations, cause or contribute to new violations, or delay timely attainment of air
quality standards or the interim emissions reductions specified in the AQMP
• Whether the proposed project would exceed the forecasted growth incorporated into the AQMP
Criterion 1:
With respect to the first criterion, SCAQMD methodologies require that an air quality analysis for a project
include forecasts of project emissions in relation to contributing to air quality violations and delay of
attainment.
Alta Fontana Mixed Use Project
Air Quality Technical Memorandum 12
a) Would the project result in an increase in the frequency or severity of existing air quality violations?
Since the consistency criteria identified under the first criterion pertain to pollutant
concentrations, rather than to total regional emissions, an analysis of a project’s pollutant
emissions relative to localized pollutant concentrations is used as the basis for evaluating project
consistency. As discussed below under Impact Statements AQ-2 and AQ-3, the project’s short-
term construction emissions, long-term operational emissions, and localized concentrations of
CO, NOX, PM10, and PM2.5 would result in less than significant impacts during project construction
and operation. Therefore, the project would not result in an increase in the frequency or severity
of existing air quality violations. Because VOCs are not a criteria pollutant, there is no ambient
standard or localized threshold for VOCs. Due to the role VOC plays in O3 formation, it is classified
as a precursor pollutant and only a regional emissions threshold has been established. The
emissions of VOCs as a result of the proposed project would not exceed the regional emissions
threshold; refer to Impact Statement AQ-2, below. As such, the project would not cause or
contribute to localized air quality violations or delay the attainment of air quality standard or
interim emissions reductions specified in the 2016 AQMP.
b) Would the project cause or contribute to new air quality violations?
As discussed below under Impact Statements AQ-2 and AQ-3, the proposed project would result
in emissions that would be below the SCAQMD’s thresholds for regional and localized emissions.
Therefore, the proposed project would not have the potential to cause or contribute to a new
violation of the ambient air quality standards.
c) Would the project delay timely attainment of air quality standards or the interim emissions
reductions specified in the AQMP?
As discussed below under Impact Statements AQ-2 and AQ-3, the proposed project would result
in less than significant impacts with regard to localized concentrations during project construction
and operation. As such, the proposed project would not delay the timely attainment of air quality
standards or 2016 AQMP interim emissions reductions.
Criterion 2:
With respect to the second criterion for determining consistency with SCAQMD and SCAG air quality
policies, it is important to recognize that air quality planning within the Basin focuses on attainment of
ambient air quality standards at the earliest feasible date. Projections for achieving air quality goals are
based on assumptions regarding population, housing, and growth trends. Thus, the SCAQMD’s second
criterion for determining project consistency focuses on whether or not the proposed project exceeds the
assumptions utilized in preparing the forecasts presented in the 2016 AQMP. Determining whether or not
a project exceeds the assumptions reflected in the 2016 AQMP involves the evaluation of the three criteria
outlined below. The following discussion provides an analysis of each of these criteria.
a) Would the project be consistent with the population, housing, and employment growth projections
utilized in the preparation of the AQMP?
A project is consistent with the 2016 AQMP in part if it is consistent with the population, housing,
and employment assumptions that were used in the development of the 2016 AQMP. In the case
Alta Fontana Mixed Use Project
Air Quality Technical Memorandum 13
of the 2016 AQMP, three sources of data form the basis for the projections of air pollutant
emissions: the General Plan Update, SCAG’s regional growth forecast, and the 2016-2040
RTP/SCS. The 2016-2040 RTP/SCS also provides socioeconomic forecast projections of regional
population growth.
The project proposes development of a mixed-use residential apartment complex with 344 units
(including four live-work units) on an 8.8-acre site, which equates to 39.1 dwelling units per acre.
The project site is designated Multi-Family High Residential (R-MFH) with a minimum of 39.1
dwelling units per acre and maximum of 50 dwelling units per acre by the General Plan Update.
Further, the project site is zoned Multi-Family High Density Residential (R5). The R5 zone is the
most intense multiple-family residential zoning district, and it provides space for high density
residential transit-oriented development commonly found in an urban environment, especially
along existing and/or anticipated future bus routes. Permitted uses include multi-story
apartments and mixed-use developments. Thus, the proposed project is considered consistent
with the General Plan Update and the City of Fontana Zoning and Development Code (Zoning
Code), and is consistent with the types, intensity, and patterns of land use envisioned for the
project site vicinity.
The City’s population estimate as of January 1, 2021, is 213,944 persons.3 Based on the City’s
average household size of 4.02,4 the proposed mixed-use development with 344 residential units
would potentially introduce approximately 1,383 additional residents within the City. As the
project would directly generate population growth through its provision of a residential
development, the project is considered growth-inducing. However, the project’s potential
growth-inducing impacts would be considered less than significant since the 1,383 additional
residents represent only a 0.65 percent increase from the City’s population of 213,944 persons.
Additionally, SCAG growth forecasts estimate the City’s population to reach 280,900 persons by
2040, representing a total increase of 80,700 persons between 2012 and 2040.5 The project’s
residential population (1,383 persons) represents approximately 1.7 percent of the City’s
anticipated growth from 2012 to 2040, and approximately 0.49 percent of the City’s total
projected 2040 population. Therefore, the project would be consistent with the buildout
population forecast in the General Plan Update. Additionally, the proposed project would be
consistent with the types, intensity, and patterns of land use envisioned for the site in the 2016-
2040 RTP/SCS. As the SCAQMD has incorporated these same projections into the 2016 AQMP, it
can be concluded that the proposed project would be consistent with the projections included in
the 2016 AQMP.
b) Would the project implement all feasible air quality mitigation measures?
The proposed project would result in less than significant air quality impacts, as demonstrated
throughout this impact analysis, and therefore, mitigation is not required. Compliance with all
feasible emission reduction rules and measures identified by the SCAQMD would be required as

identified in Impact Statements AQ-2 and AQ-3. As such, the proposed project meets this 2016
AQMP consistency criterion.
c) Would the project be consistent with the land use planning strategies set forth in the AQMP?
As discussed above under criterion 2a above, land use planning strategies set forth in the 2016
AQMP are primarily based on the 2016-2040 RTP/SCS. The project is an infill, mixed-use
development within an urban environment, which is consistent with the land use strategy set
forth in the 2016 AQMP to “Plan for Growth around Livable Corridors.” Further, the project would
comply with the 2019 California Building Energy Efficiency Standards (commonly referred to as
“Title 24” standards) and reserve area on the roof for future solar panels as well as install
enhanced insulated walls, high efficiency (LED) lighting, energy efficient appliances, low-flow
water fixtures, water-efficient irrigation, and drought tolerant landscape, which is consistent with
the land use strategy set forth in the 2016 AQMP to “Support Local Sustainability Planning.” The
project would also include approximately 53 spaces for future installation of electric vehicle
charging stations, and provide bicycle parking spaces on-site to promote alternative
transportation options, which is consistent with the land use strategies set forth in the 2016
AQMP to “Provide More Options for Short Trips/Neighborhood Mobility Areas” and “support Zero
Emission Vehicles & Expand Electric Vehicle Charging Stations.” Therefore, the project would be
consistent with the actions and strategies of the 2016-2040 RTP/SCS. As discussed above under
criterion 2a, the project would be consistent with the General Plan Update land use designation
and buildout forecast. Furthermore, project consistency with the 2016-2040 RTP/SCS and the
2016 AQMP would promote the City’s goal to improve air quality. As such, the proposed project
meets this AQMP consistency criterion.
In conclusion, the determination of 2016 AQMP consistency is primarily concerned with the long-term
influence of a project on air quality in the Basin. The proposed project would not result in a long-term
impact on the region’s ability to meet State and Federal air quality standards. Also, the proposed project
would be consistent with the goals and policies of the 2016 AQMP for control of fugitive dust; refer to
Impact Statement AQ-2. As discussed above, the operation of the proposed project would also be
consistent with the SCAQMD and SCAG’s goals and policies. Therefore, the proposed project is consistent
with the 2016 AQMP and impacts would be less than significant.
Mitigation Measures: No mitigation is required.
Level of Significance: Less Than Significant Impact.
AQ-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?
Short-Term Construction
Construction activities for the proposed project would include demolition, excavation, grading, trenching,
installation of utilities, building construction, architectural coating, paving activities, and installation of
landscaping and hardscape elements. The project would be constructed over approximately 26 months.
Exhaust emission factors for typical diesel-powered heavy equipment are based on the program defaults
of the most recent version of the California Emissions Estimator Model (CalEEMod), version 2020.4.0,
Alta Fontana Mixed Use Project
Air Quality Technical Memorandum 15
which has been used to prepare the analysis of daily construction emissions. Variables factored into
estimating the total construction emissions include the level of activity, length of construction period,
number of pieces and types of equipment in use, site characteristics, weather conditions, number of
construction personnel, and the amount of materials to be transported on- or off-site. Refer to Appendix
A, Air Quality Emissions Data, for the CalEEMod outputs and results. Table 4, Short-Term Construction
Emissions, presents the anticipated daily short-term construction emissions.

Notes:
1. Emissions were calculated using CalEEMod, version 2020.4.0. Winter emissions represent the worst-case scenario.
2. Modeling assumptions include compliance with SCAQMD Rule 403 which requires the following: properly maintain mobile and other
construction equipment; replace ground cover in disturbed areas quickly; water exposed surfaces three times daily; cover stockpiles
with tarps; water all haul roads twice daily; and limit speeds on unpaved roads to 15 miles per hour.
Source: Refer to Appendix A for detailed model input/output data.
Fugitive Dust Emissions
Construction activities are a source of fugitive dust emissions that may have a substantial, temporary
impact on local air quality. In addition, fugitive dust may be a nuisance to those living and working in the
project area. Fugitive dust emissions are associated with land clearing, ground excavation, cut-and-fill,
and truck travel on unpaved roadways. Fugitive dust emissions vary substantially from day to day,
depending on the level of activity, specific operations, and weather conditions. Fugitive dust from
demolition, grading, and construction would be short-term and would cease upon project completion. It
should be noted that most fugitive dust material is inert silicates, and not complex organic particulates
released from combustion sources which are considered more harmful to health.
Dust (larger than 10 microns) generated by construction activities usually become more of a local nuisance
than a serious health problem. Of particular health concern is the amount of PM10 generated as a part of
fugitive dust emissions. PM10 poses a serious health hazard alone or in combination with other pollutants.
PM2.5 is mostly produced by mechanical processes which include automobile tire wear, industrial
processes such as cutting and grinding, and re-suspension of particles from the ground or road surfaces
by wind and human activities such as construction or agriculture. PM2.5 is mostly derived from combustion
sources, such as automobiles, trucks, and other vehicle exhaust, as well as from stationary sources. These
particles are either directly emitted or are formed in the atmosphere from the combustion of gases such
as NOX and SOX combining with ammonia. PM2.5 components from material in the earth’s crust, such as
dust, are also present, with the amount varying in different locations.
Alta Fontana Mixed Use Project
Air Quality Technical Memorandum 16
Construction activities would comply with SCAQMD Rule 403, which requires that excessive fugitive dust
emissions be controlled by regular watering or other dust prevention measures. Adherence to SCAQMD
Rule 403 greatly reduces PM10 and PM2.5 concentrations. It should be noted that these reductions were
applied in CalEEMod. As depicted in Table 4, total PM10 and PM2.5 emissions would not exceed the
SCAQMD thresholds during construction. Therefore, construction-related air quality impacts from fugitive
dust emissions would be less than significant.
Construction Equipment and Worker Vehicle Exhaust
Exhaust emissions (e.g., NOx and CO) from construction activities include emissions associated with the
transport of machinery and supplies to and from the project site, emissions produced on-site as the
equipment is used, and emissions from trucks transporting materials to/from the site. As presented in
Table 4, short-term construction emissions, including from construction equipment and worker vehicle
exhaust, would be below the established SCAQMD thresholds. Therefore, air quality impacts from
equipment and vehicle exhaust emissions would be less than significant.
ROG Emissions
In addition to gaseous and particulate emissions, the application of asphalt and surface coatings creates
ROG emissions, which are O3 precursors. As required, all architectural coatings for the proposed project
structure would comply with SCAQMD Regulation XI, Rule 1113 – Architectural Coating. Rule 1113
provides specifications on painting practices as well as regulates the ROG content of paint. ROG emissions
associated with the proposed project would be less than significant; refer to Table 4.
Total Daily Construction Emissions
In accordance with the SCAQMD Guidelines, CalEEMod was utilized to model construction emissions for
ROG, NOX, CO, SOX, PM10, and PM2.5. As indicated in Table 4, criteria pollutant emissions during
construction of the proposed project would not exceed the SCAQMD significance thresholds. Therefore,
construction of the project would not result in a cumulatively considerable net increase of any criteria
pollutant and impacts would be less than significant.
Naturally Occurring Asbestos
Asbestos is a term used for several types of naturally occurring fibrous minerals that are a human health
hazard when airborne. The most common type of asbestos is chrysotile, but other types such as tremolite
and actinolite are also found in California. Asbestos is classified as a known human carcinogen by State,
Federal, and international agencies and was identified as a toxic air contaminant by the CARB in 1986.
Asbestos can be released from serpentinite and ultramafic rocks when the rock is broken or crushed. At
the point of release, the asbestos fibers may become airborne, causing air quality and human health
hazards. These rocks have been commonly used for unpaved gravel roads, landscaping, fill projects, and
other improvement projects in some localities. Asbestos may be released to the atmosphere due to
vehicular traffic on unpaved roads, during grading for development projects, and at quarry operations. All
of these activities may have the effect of releasing potentially harmful asbestos into the air. Natural
weathering and erosion processes can act on asbestos bearing rock and make it easier for asbestos fibers
to become airborne if such rock is disturbed. According to the Department of Conservation Division of
Mines and Geology, A General Location Guide for Ultramafic Rocks in California – Areas More Likely to
Alta Fontana Mixed Use Project
Air Quality Technical Memorandum 17
Contain Naturally Occurring Asbestos Report,6 serpentinite and ultramafic rocks are not known to occur
within the project area. Therefore, there would be no impacts related to asbestos.
Long-Term (Operational) Emissions
Long-term air quality impacts would consist of mobile source emissions generated from project-related
traffic, and emissions from stationary area and energy sources. Emissions from each source and the total
emissions are shown in Table 5, Long-Term Operational Air Emissions and discussed in more detail below.

Area Source Emissions
Area source emissions would be generated from consumer products, architectural coating, and
landscaping. As shown in Table 5, area source emissions from the proposed project would not exceed
SCAQMD thresholds for ROG, NOX, CO, SOX, PM10, or PM2.5. Impacts from area source air emissions would
be less than significant.
Energy Source Emissions
Energy source emissions would be generated as a result of electricity and natural gas (non-hearth) usage
associated with the proposed project. The primary use of electricity and natural gas by the project would

be for space heating and cooling, water heating, ventilation, lighting, appliances, and electronics. The
project would be in compliance with the 2019 Title 24 standards. As shown in Table 5, energy source
emissions from the proposed project would not exceed SCAQMD thresholds for ROG, NOX, CO, SOX, PM10,
or PM2.5. Impacts from energy source air emissions would be less than significant.
Mobile Source Emissions
Mobile sources are emissions from motor vehicles, including tailpipe and evaporative emissions.
Depending upon the pollutant being discussed, the potential air quality impact may be of either regional
or local concern. For example, ROG, NOX, SOX, PM10, and PM2.5 are all pollutants of regional concern (NOX
and ROG react with sunlight to form O3 [photochemical smog], and wind currents readily transport SOX,
PM10, and PM2.5); however, CO tends to be a localized pollutant, dispersing rapidly at the source.
Project-generated vehicle emissions were estimated using CalEEMod. According to the Alta Fontana
Apartments Traffic Study Scoping Assessment (Traffic Scoping Assessment) developed by Fehr & Peers
(dated January 13, 2022),7 the proposed project would generate 1,644 daily trips, including 131 trips
during the a.m. peak hour and 140 trips during the p.m. peak hour. As shown in Table 5, anticipated mobile
source emissions generated by vehicle traffic associated with the project would not exceed established
SCAQMD thresholds. Impacts from mobile source air emissions would be less than significant.
Criteria Air Pollutants Air Quality Health Impacts
Adverse health effects induced by criteria pollutant emissions are highly dependent on a multitude of
interconnected variables (e.g., cumulative concentrations, local meteorology and atmospheric conditions,
and the number and character of exposed individual [e.g., age, gender]). In particular, ozone precursors
ROGs and NOx affect air quality on a regional scale. Health effects related to ozone are therefore the
product of emissions generated by numerous sources throughout a region. Existing models have limited
sensitivity to small changes in criteria pollutant concentrations, and, as such, translating project-
generated criteria pollutants to specific health effects or additional days of nonattainment would produce
meaningless results. In other words, the project’s less than significant increases in regional air pollution
from criteria air pollutants would have nominal or negligible impacts on human health.
As noted in the Brief of Amicus Curiae by the SCAQMD,8 the SCAQMD acknowledged that it would be
extremely difficult, if not impossible to quantify health impacts of criteria pollutants for various reasons
including modeling limitations as well as where in the atmosphere air pollutants interact and form.
Further, as noted in the Brief of Amicus Curiae by the San Joaquin Valley Air Pollution Control District
(SJVAPCD),9 SJVAPCD has acknowledged that currently available modeling tools are not equipped to
provide a meaningful analysis of the correlation between an individual development project’s air
emissions and specific human health impacts.

Air Quality Technical Memorandum 19
The SCAQMD acknowledges that health effects quantification from ozone, as an example, is correlated
with the increases in ambient level of ozone in the air (concentration) that an individual person breathes.
SCAQMD’s Brief of Amicus Curiae states that it would take a large amount of additional emissions to cause
a modeled increase in ambient ozone levels over the entire region. The SCAQMD states that based on
their own modeling in the SCAQMD’s 2012 Air Quality Management Plan, a reduction of 432 tons (864,000
pounds) per day of NOX and a reduction of 187 tons (374,000 pounds) per day of VOCs would reduce
ozone levels at the highest monitored site by only nine parts per billion. As such, the SCAQMD concludes
that it is not currently possible to accurately quantify ozone-related health impacts caused by NOX or VOC
emissions from relatively small projects (defined as projects with regional scope) due to photochemistry
and regional model limitations. As such, for the purpose of this analysis, since the project would not
exceed SCAQMD thresholds for construction and operational air emissions, the project would have a less
than significant impact for air quality health impacts as well.
Cumulative Conclusion
With respect to the proposed project’s air quality emissions and cumulative Basin-wide conditions, the
SCAQMD has developed strategies to reduce criteria pollutant emissions, which are outlined in the 2016
AQMP pursuant to Federal Clean Air Act mandates. The proposed project would comply with SCAQMD
Rule 403 requirements and the adopted 2016 AQMP emissions control measures. Rule 403 requires that
fugitive dust be controlled with the best available control measures in order to reduce dust so that it does
not remain visible in the atmosphere beyond the property line of the proposed project. Per SCAQMD rules
and mandates, as well as the CEQA requirement that significant impacts be mitigated to the extent
feasible, these same requirements (i.e., Rule 403 compliance, the implementation of all feasible mitigation
measures, and compliance with adopted 2016 AQMP emissions control measures) would also be imposed
on development projects throughout the Basin, which would include related projects.
According to the SCAQMD CEQA Air Quality Handbook, project-related emissions that fall below the
established construction and operational thresholds should be considered less than cumulatively
significant unless there is pertinent information to the contrary. As discussed previously, the proposed
project would not result in short- or long-term air quality impacts, as emissions would not exceed the
SCAQMD adopted construction or operational thresholds. Additionally, adherence to SCAQMD rules and
regulations would alleviate potential impacts related to cumulative conditions on a project-by-project
basis. As a result, the proposed project would not contribute to a cumulatively considerable net increase
of any nonattainment criteria pollutant. Therefore, the project’s incremental construction and operational
impacts would not be considered cumulatively considerable and impacts would be less than significant.
Mitigation Measures: No mitigation is required.
Level of Significance: Less Than Significant Impact.
AQ-3 WOULD THE PROJECT EXPOSE SENSITIVE RECEPTORS TO SUBSTANTIAL POLLUTANT
CONCENTRATIONS?
Sensitive receptors are defined as facilities or land uses that include members of the population that are
particularly sensitive to the effects of air pollutants, such as children, the elderly, and people with illnesses.
Examples of these sensitive receptors are residences, schools, hospitals, and daycare centers. CARB has
identified the following groups of individuals as the most likely to be affected by air pollution: the elderly
Alta Fontana Mixed Use Project
Air Quality Technical Memorandum 20
over 65, children under 14, athletes, and persons with cardiovascular and chronic respiratory diseases
such as asthma, emphysema, and bronchitis.
The nearest sensitive receptors for the LST analysis are single-family residences adjacent to the south of
the project site. In order to identify impacts to sensitive receptors, the SCAQMD recommends addressing
LSTs for construction and operations impacts (area sources only). The CO hotspot analysis, following the
LST analysis, addresses localized mobile source impacts.
Localized Significance Thresholds
LSTs were developed in response to SCAQMD Governing Boards’ Environmental Justice Enhancement
Initiative (I-4). The SCAQMD provided the Final Localized Significance Threshold Methodology (dated June
2003 [revised 2008])10 for guidance. The LST methodology assists lead agencies in analyzing localized air
quality impacts. The SCAQMD provides the LST screening lookup tables for one-, two-, and five-acre
projects emitting CO, NOX, PM2.5, or PM10. The LST methodology and associated mass rates are not
designed to evaluate localized impacts from mobile sources traveling over the roadways. The project site
is located in SRA 34 (Central San Bernardino Valley).
Construction
The SCAQMD’s guidance on applying CalEEMod to LSTs specifies the number of acres a particular piece of
equipment would likely disturb per day. Based on default information provided by CalEEMod, the project
is anticipated to disturb up to 33 acres (an average of approximately one acre per day) during the grading
phase, which would take approximately 33 days to complete. Therefore, the LST thresholds for one acre
was utilized for the construction LST analysis per SCAQMD guidance. The nearest sensitive uses are single-
family residences adjacent to the south of the project site. LST thresholds are provided for distances to
sensitive receptors of 25, 50, 100, 200, and 500 meters. According to SCAQMD LST methodology, projects
with boundaries located closer than 25 meters to the nearest receptor should use the LSTs for receptors
located at 25 meters. As the nearest sensitive receptors are adjacent to the project site, the LST values for
25 meters were used.
Table 6, Localized Significance of Construction Emissions, shows the localized construction-related
emissions. It is noted that the localized emissions presented in Table 6 are less than those in Table 4
because localized emissions include only on-site emissions (i.e., from construction equipment and fugitive
dust). As seen in Table 6, emissions would not exceed the LST mass rate screening thresholds for SRA 34.
Therefore, impacts related to construction LST would be less than significant.

Note:
1. Maximum on-site daily emissions occur during grading phase for NOx, PM10, and PM2.5, and during building construction phase for CO
in Year 1. 2. Maximum on-site daily emissions occur during grading phase for NOx, PM10, and PM2.5, and during building construction phase for CO
in Year 2.
3. Maximum on-site daily emissions occur during building construction phase for NOx, CO, PM10, and PM2.5 in Year 3.
4. Modeling assumptions include compliance with SCAQMD Rule 403 which requires the following: properly maintain mobile and other
construction equipment; replace ground cover in disturbed areas quickly; water exposed surfaces three times daily; cover stockpiles
with tarps; water all haul roads twice daily; and limit speeds on unpaved roads to 15 miles per hour. 5. The Localized Significance Threshold Mass Rate Screening Criteria was determined using Appendix C of the SCAQMD Final Localized
Significant Threshold Methodology guidance document for pollutants NOX, CO, PM10, and PM2.5. The Localized Significance Threshold
Mass Rate Screening Threshold was based on the anticipated daily acreage disturbance for construction (one acre), the distance to sensitive receptors (25 meters), and the source receptor area (SRA 34).
Operation
According to SCAQMD LST methodology, LSTs would apply to the operational phase of a proposed project
if the project includes stationary sources or attracts mobile sources that may spend extended periods
queuing and idling at the site (e.g., warehouse or transfer facilities). The proposed project does not include
such uses. Thus, due to the lack of such emissions, no long-term localized significance threshold analysis
is necessary. Therefore, impacts related to operational LST would be less than significant.
Carbon Monoxide Hotspots
CO emissions are a function of vehicle idling time, meteorological conditions, and traffic flow. Under
certain extreme meteorological conditions, CO concentrations near a congested roadway or intersection
may reach unhealthful levels (i.e., adversely affecting residents, school children, hospital patients, the
elderly, etc.).
The SCAQMD recommends a quantified assessment of CO hotspots when a project increases the volume-
to-capacity ratio (also called the intersection capacity utilization) by 0.02 (two percent) for any
intersection with an existing level of service (LOS) D or worse. Because traffic congestion is highest at
intersections where vehicles queue and are subject to reduced speeds, these hot spots are typically
produced at intersections.
The Basin is designated as an attainment/maintenance area for the Federal CO standards and an
attainment area for State standards. There has been a decline in CO emissions even though vehicle miles
traveled on U.S. urban and rural roads have increased. Nationwide estimated anthropogenic CO emissions
Alta Fontana Mixed Use Project
Air Quality Technical Memorandum 22
have decreased 68 percent between 1990 and 2014. In 2014, mobile sources accounted for 82 percent of
the nation’s total anthropogenic CO emissions.11 CO emissions have continued to decline since this time.
The Basin was re-designated as attainment in 2007 and CO is no longer addressed in the SCAQMD’s AQMP.
Three major control programs have contributed to the reduced per-vehicle CO emissions: exhaust
standards, cleaner burning fuels, and motor vehicle inspection/maintenance programs.
A detailed CO analysis was conducted in the Federal Attainment Plan for Carbon Monoxide (CO Plan) for
the SCAQMD’s 2003 Air Quality Management Plan, which is the most recent AQMP that addresses CO
concentrations. The locations selected for microscale modeling in the CO Plan are worst-case intersections
in the Basin and would likely experience the highest CO concentrations. Thus, CO analysis within the CO
Plan is utilized in a comparison to the proposed project, since it represents a worst-case scenario with
heavy traffic volumes within the Basin.
Of these locations, the Wilshire Boulevard/Veteran Avenue intersection in Los Angeles County
experienced the highest CO concentration (4.6 parts per million [ppm]), which is well below the 35-ppm
one-hour CO Federal standard. The Wilshire Boulevard/Veteran Avenue intersection is one of the most
congested intersections in Southern California with an average daily traffic volume of approximately
100,000 vehicles per day. As the CO hotspots were not experienced at the Wilshire Boulevard/Veteran
Avenue intersection, it can be reasonably inferred that CO hotspots would not be experienced at any
intersections within the City of Fontana near the project site due to the comparatively low volume of
traffic (an increase of 1,644 daily trips, including 131 trips during the a.m. peak hour and 140 trips during
the p.m. peak hour) that would occur as a result of project implementation. Therefore, impacts would be
less than significant.
Mitigation Measures: No mitigation is required.
Level of Significance: Less Than Significant Impact.
AQ-4 WOULD THE PROJECT RESULT IN OTHER EMISSIONS (SUCH AS THOSE LEADING TO ODORS)
ADVERSELY AFFECTING A SUBSTANTIAL NUMBER OF PEOPLE?
According to the SCAQMD CEQA Air Quality Handbook, land uses associated with odor complaints typically
include agricultural uses, wastewater treatment plants, food processing plants, chemical plants,
composting, refineries, landfills, dairies, and fiberglass molding. The proposed mixed-use project does not
include any uses identified by the SCAQMD as being associated with odors.
Construction activities associated with the project may generate detectable odors from heavy-duty
equipment exhaust and architectural coatings. However, construction-related odors would be short-term
in nature and cease upon project construction completion. In addition, the project would be required to
comply with the California Code of Regulations, Title 13, Sections 2449(d)(3) and 2485, which minimizes
the idling time of construction equipment either by shutting it off when not in use or by reducing the time
of idling to no more than five minutes. This would further reduce the detectable odors from heavy-duty
equipment exhaust. The project would also comply with the SCAQMD Regulation XI, Rule 1113 –
Architectural Coating, which would minimize odor impacts from ROG emissions during architectural
coating. Any impacts to existing adjacent land uses would be short-term and would be less than significant.
