METEOROLOGICAL SETTING

The climate of Azusa, as with all of Southern California, is governed largely by the strength and

location of the semi-permanent high-pressure center over the Pacific Ocean and the moderating

effects of the nearby vast oceanic heat reservoir. Local climatic conditions are characterized by

very warm summers, mild winters, infrequent rainfall, moderate daytime on-shore breezes, and

comfortable humidities. Unfortunately, the same climatic conditions that create such a desirable

living climate combine to severely restrict the ability of the local atmosphere to disperse the large

volumes of air pollution generated by the population and industry attracted in part by the climate.

Azusa is situated in an area where the pollutants generated in coastal portions of the Los Angeles

basin undergo photochemical reactions and then move inland across the project site during the

daily sea breeze cycle. The resulting smog at times gives the western San Gabriel Valley some of

the worst air quality in all of California. The worst air quality, however, has gradually been moving

eastward. The area of heaviest ozone air pollution has gradually moved eastward from Pasadena

in the 1960’s to Glendora and even Upland/Ontario in the 1990’s. Elevated smog levels

nevertheless persist in the El Monte area during the warmer months of the year. Despite dramatic

improvement in air quality in the local area throughout the last several decades, the project site is

expected to continue to experience some unhealthful air quality until beyond 2020.

Temperatures in the project vicinity average 62 degrees Fahrenheit annually with summer

afternoons in the low 90s and winter mornings in the low 40s. Temperatures much above 100 or

below 30 degrees occur infrequently only under unusual weather conditions and even then these

limits are not far exceeded.

In contrast to the slow annual variation of temperature, precipitation is highly variable seasonally.

Rainfall in the San Gabriel Valley averages 14 inches annually and falls almost exclusively from

late October to early April. Summers are very dry with frequent periods of 4-5 months of no rain

at all. Because much of the rainfall comes from the fringes of mid-latitude storms, a shift in the

storm track of a few hundred miles can mean the difference between a very wet year and a year

with drought conditions.

Winds across the project area are an important meteorological parameter because they control both

the initial rate of dilution of locally generated air pollutant emissions as well as their regional

trajectory. Local wind patterns show a fairly unidirectional daytime onshore flow from the SW-

W with a very weak offshore return flow from the NE that is strongest on winter nights when the

land is colder than the ocean. The onshore winds during the day average 6-8 mph, while the

offshore flow is often calm or drifts slowly westward at 1-3 mph. During the daytime, any locally

generated air emissions are thus transported eastward toward San Bernardino and Cajon Pass

without generating any localized air quality impacts.

The drainage winds which move slowly across the area at night have some potential for localized

stagnation. Fortunately, these winds have their origin in the San Gabriel Mountains where

background pollution levels are low such that any localized contributions do not create any

unhealthful impacts. The wind distribution is such that nominal project-related air quality impacts

occur more on a regional scale rather than in the immediate Azusa area. One other important wind


- 2 -

condition occurs when a high pressure center forms over the western United States with sinking

air forced seaward through local canyons and mountain passes. The air warms by compression

and relative humidities drop dramatically. The dry, gusty winds from the N-NE create dust

nuisance potential around areas of soil disturbance such as construction sites.

In conjunction with the two dominant wind regimes that affect the rate and orientation of horizontal

pollutant transport, there are two similarly distinct types of temperature inversions that control the

vertical depth through which pollutants are mixed. The summer on-shore flow is capped by a

massive dome of warm, sinking air which caps a shallow layer of cooler ocean air. These

marine/subsidence inversions act like a giant lid over the basin. They allow for local mixing of

emissions, but they confine the entire polluted air mass within the basin until it escapes into the

desert or along the thermal chimneys formed along heated mountain slopes.

In winter, when the air near the ground cools while the air aloft remains warm, radiation inversions

are formed that trap low-level emissions such as automobile exhaust near their source. As

background levels of primary vehicular exhaust rise during the seaward return flow, the

combination of rising non-local baseline levels plus emissions trapped locally by these radiation

inversions creates micro-scale air pollution "hot spots" near freeways, shopping centers and other

traffic concentrations. Because the incoming air draining off the mountains into the San Gabriel

Valley during nocturnal radiation inversion conditions is relatively clean, the summer subsidence

inversions are a far more critical factor in determining Azusa area air quality than the winter time

local trapping inversions.

AIR QUALITY SETTING

AMBIENT AIR QUALITY STANDARDS (AAQS)

In order to gauge the significance of the air quality impacts of the proposed project, those impacts,

together with existing background air quality levels, must be compared to the applicable ambient

air quality standards. These standards are the levels of air quality considered safe, with an adequate

margin of safety, to protect the public health and welfare. They are designed to protect those

people most susceptible to further respiratory distress such as asthmatics, the elderly, very young

children, people already weakened by other disease or illness, and persons engaged in strenuous

work or exercise, called "sensitive receptors." Healthy adults can tolerate occasional exposure to

air pollutant concentrations considerably above these minimum standards before adverse effects

are observed. Recent research has shown, however, that chronic exposure to ozone (the primary

ingredient in photochemical smog) may lead to adverse respiratory health even at concentrations

close to the ambient standard.

National AAQS were established in 1971 for six pollution species with states retaining the option

to add other pollutants, require more stringent compliance, or to include different exposure periods.

The initial attainment deadline of 1977 was extended several times in air quality problem areas

like Southern California. In 2003, the Environmental Protection Agency (EPA) adopted a rule,

which extended and established a new attainment deadline for ozone for the year 2021. Because

the State of California had established AAQS several years before the federal action and because

of unique air quality problems introduced by the restrictive dispersion meteorology, there is

considerable difference between state and national clean air standards. Those standards currently

in effect in California are shown in Table 1. Sources and health effects of various pollutants are

shown in Table 2.

The Federal Clean Air Act Amendments (CAAA) of 1990 required that the U.S. Environmental

Protection Agency (EPA) review all national AAQS in light of currently known health effects.

EPA was charged with modifying existing standards or promulgating new ones where appropriate.

EPA subsequently developed standards for chronic ozone exposure (8+ hours per day) and for

very small diameter particulate matter (called "PM-2.5"). New national AAQS were adopted in

1997 for these pollutants.

Planning and enforcement of the federal standards for PM-2.5 and for ozone (8-hour) were

challenged by trucking and manufacturing organizations. In a unanimous decision, the U.S.

Supreme Court ruled that EPA did not require specific congressional authorization to adopt

national clean air standards. The Court also ruled that health-based standards did not require

preparation of a cost-benefit analysis. The Court did find, however, that there was some

inconsistency between existing and "new" standards in their required attainment schedules. Such

attainment-planning schedule inconsistencies centered mainly on the 8-hour ozone standard. EPA

subsequently agreed to downgrade the attainment designation for a large number of communities

to “non-attainment” for the 8-hour ozone standard.

Evaluation of the most current data on the health effects of inhalation of fine particulate matter

prompted the California Air Resources Board (ARB) to recommend adoption of the statewide

PM-2.5 standard that is more stringent than the federal standard. This standard was adopted in

2002. The State PM-2.5 standard is more of a goal in that it does not have specific attainment

planning requirements like a federal clean air standard, but only requires continued progress

towards attainment.

Similarly, the ARB extensively evaluated health effects of ozone exposure. A new state standard

for an 8-hour ozone exposure was adopted in 2005, which aligned with the exposure period for the

federal 8-hour standard. The California 8-hour ozone standard of 0.07 ppm is more stringent than

the federal 8-hour standard of 0.075 ppm. The state standard, however, does not have a specific

attainment deadline. California air quality jurisdictions are required to make steady progress

towards attaining state standards, but there are no hard deadlines or any consequences of non-

attainment. During the same re-evaluation process, the ARB adopted an annual state standard for

nitrogen dioxide (NO2) that is more stringent than the corresponding federal standard, and

strengthened the state one-hour NO2 standard.

As part of EPA’s 2002 consent decree on clean air standards, a further review of airborne

particulate matter (PM) and human health was initiated. A substantial modification of federal

clean air standards for PM was promulgated in 2006. Standards for PM-2.5 were strengthened, a

new class of PM in the 2.5 to 10 micron size was created, some PM-10 standards were revoked,

and a distinction between rural and urban air quality was adopted. In December, 2012, the federal

annual standard for PM-2.5 was reduced from 15 g/m3 to 12 g/m3 which matches the California

AAQS. The severity of the basin’s non-attainment status for PM-2.5 may be increased by this

action and thus require accelerated planning for future PM-2.5 attainment.

In response to continuing evidence that ozone exposure at levels just meeting federal clean air

standards is demonstrably unhealthful, EPA had proposed a further strengthening of the 8-hour

standard. A new 8-hour ozone standard was adopted in 2015 after extensive analysis and public

input. The adopted national 8-hour ozone standard is 0.07 ppm which matches the current

California standard. It will require three years of ambient data collection, then 2 years of non-

attainment findings and planning protocol adoption, then several years of plan development and

approval. Final air quality plans for the new standard are likely to be adopted around 2022.

Ultimate attainment of the new standard in ozone problem areas such as Southern California might

be after 2025.

In 2010 a new federal one-hour primary standard for nitrogen dioxide (NO2) was adopted. This

standard is more stringent than the existing state standard. Based upon air quality monitoring data

in the South Coast Air Basin, the California Air Resources Board has requested the EPA to

designate the basin as being in attainment for this standard. The federal standard for sulfur dioxide

(SO2) was also recently revised. However, with minimal combustion of coal and mandatory use of

low sulfur fuels in California, SO2 is typically not a problem pollutant.

BASELINE AIR QUALITY

Existing levels of ambient air quality and historical trends in the project area are best documented

by measurements made by SCAQMD at its Azusa Monitoring Station. This station measures both

regional pollution levels such as dust (particulates) and smog, as well as levels of primary vehicular

pollutants such as carbon monoxide. Table 3 is a 5-year summary of monitoring data for the major

air pollutants compiled from this air monitoring station.

a. Photochemical smog (ozone) levels occasionally exceed standards. The 8-hour state ozone

standard was exceeded on five percent of all measured days and the 1-hour state standard

have been exceeded on approximately four percent of all days in the past five years. The

8-hour federal standard has been exceeded on three percent of days for the same period.

While ozone levels are still high, they are much lower than 10 to 20 years ago. Attainment

of all clean air standards in the project vicinity is not likely to occur soon, but the severity

and frequency of violations is expected to continue to slowly decline during the current

decade.

b. Measurements of carbon monoxide have shown very low baseline levels in comparison to

the most stringent one- and eight-hour standards.

c. Respirable dust (PM-10) levels exceed the state standard on approximately 17 percent of

measurement days, but the less stringent federal PM-10 standard has not been violated for

the same period. Year to year fluctuations of overall maximum 24-hour PM-10 levels seem

to follow no discernable trend, though 2011 had the lowest maximum 24-hour

concentration and 2015 the highest in recent history.

d. A substantial fraction of PM-10 is comprised of ultra-small diameter particulates capable

of being inhaled into deep lung tissue (PM-2.5). Year 2013 showed the fewest violations

in recent years. Both the frequency of violations of particulate standards, as well as high

percentage of PM-2.5, are occasional air quality concerns in the project area. Less than

one percent of all days exceeded the current national 24-hour standard of 35 g/m3 from

2011-2015 with only five violations of measured days.

Although complete attainment of every clean air standard is not yet imminent, extrapolation of the

steady improvement trend suggests that such attainment could occur within the reasonably near

future.

AIR QUALITY PLANNING

The Federal Clean Air Act (1977 Amendments) required that designated agencies in any area of

the nation not meeting national clean air standards must prepare a plan demonstrating the steps

that would bring the area into compliance with all national standards. The SCAB could not meet

the deadlines for ozone, nitrogen dioxide, carbon monoxide, or PM-10. In the SCAB, the agencies

designated by the governor to develop regional air quality plans are the SCAQMD and the

Southern California Association of Governments (SCAG). The two agencies first adopted an Air

Quality Management Plan (AQMP) in 1979 and revised it several times as earlier attainment

forecasts were shown to be overly optimistic.

The 1990 Federal Clean Air Act Amendment (CAAA) required that all states with air-sheds with

“serious” or worse ozone problems submit a revision to the State Implementation Plan (SIP).

Amendments to the SIP have been proposed, revised and approved over the past decade. The most

current regional attainment emissions forecast for ozone precursors (ROG and NOx) and for

carbon monoxide (CO) and for particulate matter are shown in Table 4. Substantial reductions in

emissions of ROG, NOx and CO are forecast to continue throughout the next several decades.

Unless new particulate control programs are implemented, PM-10 and PM-2.5 are forecast to

slightly increase.

The Air Quality Management District (AQMD) adopted an updated clean air “blueprint” in August

2003. The 2003 Air Quality Management Plan (AQMP) was approved by the EPA in 2004. The

AQMP outlined the air pollution measures needed to meet federal health-based standards for ozone

by 2010 and for particulates (PM-10) by 2006. The 2003 AQMP was based upon the federal one-

hour ozone standard which was revoked late in 2005 and replaced by an 8-hour federal standard.

Because of the revocation of the hourly standard, a new air quality planning cycle was initiated.

With re-designation of the air basin as non-attainment for the 8-hour ozone standard, a new

attainment plan was developed. This plan shifted most of the one-hour ozone standard attainment

strategies to the 8-hour standard. As previously noted, the attainment date was to “slip” from 2010

to 2021. The updated attainment plan also includes strategies for ultimately meeting the federal

PM-2.5 standard.

Because projected attainment by 2021 required control technologies that did not exist yet, the

SCAQMD requested a voluntary “bump-up” from a “severe non-attainment” area to an “extreme

non-attainment” designation for ozone. The extreme designation was to allow a longer time period

for these technologies to develop. If attainment cannot be demonstrated within the specified

deadline without relying on “black-box” measures, EPA would have been required to impose

sanctions on the region had the bump-up request not been approved. In April 2010, the EPA

approved the change in the non-attainment designation from “severe-17” to “extreme.” This

reclassification set a later attainment deadline (2024), but also required the air basin to adopt even

more stringent emissions controls.

In other air quality attainment plan reviews, EPA had disapproved part of the SCAB PM-2.5

attainment plan included in the AQMP. EPA stated that the current attainment plan relied on PM-

2.5 control regulations that had not yet been approved or implemented. It was expected that a

number of rules that were pending approval would remove the identified deficiencies. If these

issues were not resolved within the next several years, federal funding sanctions for transportation

projects could result. The 2012 AQMP included in the current California State Implementation

Plan (SIP) was expected to remedy identified PM-2.5 planning deficiencies.

The federal Clean Air Act requires that non-attainment air basins have EPA approved attainment

plans in place. This requirement includes the federal one-hour ozone standard even though that

standard was revoked around eight years ago. There was no approved attainment plan for the one-

hour federal standard at the time of revocation. Through a legal quirk, the SCAQMD is now

required to develop an AQMP for the long since revoked one-hour federal ozone standard. Because

the current SIP for the basin contains a number of control measures for the 8-hour ozone standard

that are equally effective for one-hour levels, the 2012 AQMP was believed to satisfy hourly

attainment planning requirements.

AQMPs are required to be updated every three years. The 2012 AQMP was adopted in early 2013.

An updated AQMP was required for completion in 2016. The 2016 AQMP was adopted by the

SCAQMD Board in March, 2017, and has been submitted the California Air Resources Board for

forwarding to the EPA. The 2016 AQMP acknowledges that motor vehicle emissions have been

effectively controlled and that reductions in NOx, the continuing ozone problem pollutant, may

need to come from major stationary sources (power plants, refineries, landfill flares, etc.) . The

current attainment deadlines for all federal non-attainment pollutants are now as follows:

8-hour ozone (70 ppb) 2032

Annual PM-2.5 (12 g/m3) 2025

8-hour ozone (75 ppb) 2024 (old standard)

1-hour ozone (120 ppb) 2023 (rescinded standard)

24-hour PM-2.5 (35 g/m3) 2019


- 12 -

The key challenge is that NOx emission levels, as a critical ozone precursor pollutant, are forecast

to continue to exceed the levels that would allow the above deadlines to be met. Unless additional

stringent NOx control measures are adopted and implemented, ozone attainment goals may not be

met.

The proposed project does not directly relate to the AQMP in that there are no specific air quality

programs or regulations governing senior living projects. Conformity with adopted plans, forecasts

and programs relative to population, housing, employment and land use is the primary yardstick

by which impact significance of planned growth is determined. The SCAQMD, however, while

acknowledging that the AQMP is a growth-accommodating document, does not favor designating

regional impacts as less-than-significant just because the proposed development is consistent with

regional growth projections. Air quality impact significance for the proposed project has therefore

been analyzed on a project-specific basis.


- 13 -

AIR QUALITY IMPACT

STANDARDS OF SIGNIFICANCE

Air quality impacts are considered “significant” if they cause clean air standards to be violated

where they are currently met, or if they “substantially” contribute to an existing violation of

standards. Any substantial emissions of air contaminants for which there is no safe exposure, or

nuisance emissions such as dust or odors, would also be considered a significant impact.

Appendix G of the California CEQA Guidelines offers the following five tests of air quality impact

significance. A project would have a potentially significant impact if it:

a. Conflicts with or obstructs implementation of the applicable air quality plan.

b. Violates any air quality standard or contributes substantially to an existing or projected air

quality violation.

c. Results in a cumulatively considerable net increase of any criteria pollutants for which the

project region is non-attainment under an applicable federal or state ambient air quality

standard (including releasing emissions which exceed quantitative thresholds for ozone

precursors).

d. Exposes sensitive receptors to substantial pollutant concentrations.

e. Creates objectionable odors affecting a substantial number of people.

Primary Pollutants

Air quality impacts generally occur on two scales of motion. Near an individual source of

emissions or a collection of sources such as a crowded intersection or parking lot, levels of those

pollutants that are emitted in their already unhealthful form will be highest. Carbon monoxide

(CO) is an example of such a pollutant. Primary pollutant impacts can generally be evaluated

directly in comparison to appropriate clean air standards. Violations of these standards where they

are currently met, or a measurable worsening of an existing or future violation, would be

considered a significant impact. Many particulates, especially fugitive dust emissions, are also

primary pollutants. Because of the non-attainment status of the South Coast Air Basin (SCAB)

for PM-10, an aggressive dust control program is required to control fugitive dust during project

construction.

Secondary Pollutants

Many pollutants, however, require time to transform from a more benign form to a more

unhealthful contaminant. Their impact occurs regionally far from the source. Their incremental

regional impact is minute on an individual basis and cannot be quantified except through complex

photochemical computer models. Analysis of significance of such emissions is based upon a


- 14 -

specified amount of emissions (pounds, tons, etc.) even though there is no way to translate those

emissions directly into a corresponding ambient air quality impact.

Because of the chemical complexity of primary versus secondary pollutants, the SCAQMD has

designated significant emissions levels as surrogates for evaluating regional air quality impact

significance independent of chemical transformation processes. Projects with daily emissions that

exceed any of the following emission thresholds are recommended by the SCAQMD to be

considered significant under CEQA guidelines.

Table 5

Daily Emissions Thresholds

Additional Indicators

In its CEQA Handbook, the SCAQMD also states that additional indicators should be used as

screening criteria to determine the need for further analysis with respect to air quality. The

additional indicators are as follows:

Project could interfere with the attainment of the federal or state ambient air quality

standards by either violating or contributing to an existing or projected air quality violation

Project could result in population increases within the regional statistical area which would

be in excess of that projected in the AQMP and in other than planned locations for the

project’s build-out year.

Project could generate vehicle trips that cause a CO hot spot.

CONSTRUCTION ACTIVITY IMPACTS

CalEEMod was developed by the SCAQMD to provide a model by which to calculate both

construction emissions and operational emissions from a variety of land use projects. It calculates

both the daily maximum and annual average emissions for criteria pollutants as well as total or

annual greenhouse gas (GHG) emissions.

Although exhaust emissions will result from on and off-site equipment, the exact types and

numbers of equipment will vary among contractors such that such emissions cannot be quantified

with certainty. Estimated construction emissions were modeled using CalEEMod2016.3.1 to

identify maximum daily emissions for each pollutant during project construction.

The proposed project entails demolition of three existing structures and construction of 60 units of

senior living space. Construction was modeled in CalEEMod2013.2.2 using default construction

equipment and schedule for a project of this size as shown in Table 6.

Peak daily construction activity emissions are estimated be below SCAQMD CEQA thresholds

without the need for added mitigation. The only model-based mitigation measured applied for this

project was:

Water exposed dirt surfaces two times per day to minimize the generation of fugitive dust

generation during grading.

Construction equipment exhaust contains carcinogenic compounds within the diesel exhaust

particulates. The toxicity of diesel exhaust is evaluated relative to a 24-hour per day, 365 days per

year, 70-year lifetime exposure. The SCAQMD does not generally require the analysis of

construction-related diesel emissions relative to health risk due to the short period for which the

majority of diesel exhaust would occur. Health risk analyses are typically assessed over a 9-, 30-,

or 70-year timeframe and not over a relatively brief construction period due to the lack of health

risk associated with such a brief exposure.

LOCALIZED SIGNIFICANCE THRESHOLDS

The SCAQMD has developed analysis parameters to evaluate ambient air quality on a local level

in addition to the more regional emissions-based thresholds of significance. These analysis

elements are called Localized Significance Thresholds (LSTs). LSTs were developed in response

to Governing Board’s Environmental Justice Enhancement Initiative 1-4 and the LST

methodology was provisionally adopted in October 2003 and formally approved by SCAQMD’s

Mobile Source Committee in February 2005.

Use of an LST analysis for a project is optional. For the proposed project, the primary source of

possible LST impact would be during construction. LSTs are applicable for a sensitive receptor

where it is possible that an individual could remain for 24 hours such as a residence, hospital or

convalescent facility.

LSTs are only applicable to the following criteria pollutants: oxides of nitrogen (NOx), carbon

monoxide (CO), and particulate matter (PM-10 and PM-2.5). LSTs represent the maximum

emissions from a project that are not expected to cause or contribute to an exceedance of the most


- 17 -

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 distance to the nearest

sensitive receptor.

LST screening tables are available for 25, 50, 100, 200 and 500 meter source-receptor distances.

For this project, the nearest sensitive receptors are the residential uses adjacent to the project site

such that the most conservative 25 meter distance was modeled.

The SCAQMD has issued guidance on applying CalEEMod to LSTs. LST pollutant screening

level concentration data is currently published for 1, 2 and 5 acre sites for varying distances. For

this project, the most stringent thresholds for a 1 acre site were applied. The following thresholds

and emissions in Table 8 are therefore determined (pounds per day):

LSTs were compared to the maximum daily construction activities. As seen above, emissions will meet the LST for construction thresholds with the application of the following mitigation measure:

Exposed surfaces will be watered two times per day during grading activities LST impacts are less-than-significant with the application of this mitigation measure.

OPERATIONAL IMPACTS

Operational emissions were calculated using CalEEMod2016.3.1 for an assumed project opening

year of 2019. Trip rates were provided in the project traffic report. The traffic report predicts that

the project will generate 206 new daily trips. Although some trips are off-set by the existing three

homes, the worst-case assumption that all trips are new was quantified since results are much less

than significant.

In addition to mobile sources from vehicles, general development causes smaller amounts of “area

source” air pollution to be generated from on-site energy consumption and from off-site electrical

generation. These sources represent a minimal percentage of the total project NOx and CO

burdens, and a few percent other pollutants. The inclusion of such emissions adds negligibly to

the total significant project-related emissions burden as shown in Table 9.

As seen in Table 9, the project would not cause any operational emissions to exceed their

respective SCAQMD CEQA significance thresholds. Operational emission impacts are judged to

be less than significant. No impact mitigation for operational activity emissions is considered

necessary to support this finding.

CONSTRUCTION EMISSIONS MINIMIZATION

Construction activities are not anticipated to cause dust emissions to exceed SCAQMD CEQA

thresholds. Nevertheless, emissions minimization through enhanced dust control measures is

recommended for use because of the non-attainment status of the air basin. Recommended

measures include:

Fugitive Dust Control

Apply soil stabilizers or moisten inactive areas.

Water exposed surfaces as needed to avoid visible dust leaving the construction site

(typically 2-3 times/day).

Cover all stock piles with tarps at the end of each day or as needed.

Provide water spray during loading and unloading of earthen materials.

Minimize in-out traffic from construction zone

Cover all trucks hauling dirt, sand, or loose material and require all trucks to maintain at

least two feet of freeboard

Sweep streets daily if visible soil material is carried out from the construction site

Similarly, ozone precursor emissions (ROG and NOx) are calculated to be below SCAQMD

CEQA thresholds. However, because of the regional non-attainment for photochemical smog, the

use of reasonably available control measures for diesel exhaust is recommended. Combustion

emissions control options include:


- 19 -

Exhaust Emissions Control

Utilize well-tuned off-road construction equipment.

Establish a preference for contractors using Tier 3 or better rated heavy equipment.

Enforce 5-minute idling limits for both on-road trucks and off-road equipment.

GREENHOUSE GAS EMISSIONS

“Greenhouse gases” (so called because of their role in trapping heat near the surface of the earth)

emitted by human activity are implicated in global climate change, commonly referred to as

“global warming.” These greenhouse gases contribute to an increase in the temperature of the

earth’s atmosphere by transparency to short wavelength visible sunlight, but near opacity to

outgoing terrestrial long wavelength heat radiation in some parts of the infrared spectrum. The

principal greenhouse gases (GHGs) are carbon dioxide, methane, nitrous oxide, ozone, and water

vapor. For purposes of planning and regulation, Section 15364.5 of the California Code of

Regulations defines GHGs to include carbon dioxide, methane, nitrous oxide, hydrofluorocarbons,

perfluorocarbons and sulfur hexafluoride. Fossil fuel consumption in the transportation sector (on-

road motor vehicles, off-highway mobile sources, and aircraft) is the single largest source of GHG

emissions, accounting for approximately half of GHG emissions globally. Industrial and

commercial sources are the second largest contributors of GHG emissions with about one-fourth

of total emissions.

California has passed several bills and the Governor has signed at least three executive orders

regarding greenhouse gases. GHG statues and executive orders (EO) include AB 32, SB 1368,

EO S-03-05, EO S-20-06 and EO S-01-07.

AB 32 is one of the most significant pieces of environmental legislation that California has

adopted. Among other things, it is designed to maintain California’s reputation as a “national and

international leader on energy conservation and environmental stewardship.” It will have wide-

ranging effects on California businesses and lifestyles as well as far reaching effects on other states

and countries. A unique aspect of AB 32, beyond its broad and wide-ranging mandatory provisions

and dramatic GHG reductions are the short time frames within which it must be implemented.

Major components of the AB 32 include:

Require the monitoring and reporting of GHG emissions beginning with sources or

categories of sources that contribute the most to statewide emissions.

Requires immediate “early action” control programs on the most readily controlled GHG

sources.

Mandates that by 2020, California’s GHG emissions be reduced to 1990 levels.

Forces an overall reduction of GHG gases in California by 25-40%, from business as usual,

to be achieved by 2020.

Must complement efforts to achieve and maintain federal and state ambient air quality

standards and to reduce toxic air contaminants.

Statewide, the framework for developing the implementing regulations for AB 32 is under way.

Maximum GHG reductions are expected to derive from increased vehicle fuel efficiency, from

greater use of renewable energy and from increased structural energy efficiency. Additionally,

through the California Climate Action Registry (CCAR now called the Climate Action Reserve),

general and industry-specific protocols for assessing and reporting GHG emissions have been


- 21 -

developed. GHG sources are categorized into direct sources (i.e. company owned) and indirect

sources (i.e. not company owned). Direct sources include combustion emissions from on-and off-

road mobile sources, and fugitive emissions. Indirect sources include off-site electricity generation

and non-company owned mobile sources.

THRESHOLDS OF SIGNIFICANCE

In response to the requirements of SB97, the State Resources Agency developed guidelines for the

treatment of GHG emissions under CEQA. These new guidelines became state laws as part of

Title 14 of the California Code of Regulations in March, 2010. The CEQA Appendix G guidelines

were modified to include GHG as a required analysis element. A project would have a potentially

significant impact if it:

Generates GHG emissions, directly or indirectly, that may have a significant impact on the

environment, or,

Conflicts with an applicable plan, policy or regulation adopted to reduce GHG emissions.

Section 15064.4 of the Code specifies how significance of GHG emissions is to be evaluated. The

process is broken down into quantification of project-related GHG emissions, making a

determination of significance, and specification of any appropriate mitigation if impacts are found

to be potentially significant. At each of these steps, the new GHG guidelines afford the lead agency

with substantial flexibility.

Emissions identification may be quantitative, qualitative or based on performance standards.

CEQA guidelines allow the lead agency to “select the model or methodology it considers most

appropriate.” The most common practice for transportation/combustion GHG emissions

quantification is to use a computer model such as CalEEMod, as was used in the ensuing analysis.

The significance of those emissions then must be evaluated; the selection of a threshold of

significance must take into consideration what level of GHG emissions would be cumulatively

considerable. The guidelines are clear that they do not support a zero net emissions threshold. If

the lead agency does not have sufficient expertise in evaluating GHG impacts, it may rely on

thresholds adopted by an agency with greater expertise.

On December 5, 2008 the SCAQMD Governing Board adopted an Interim quantitative GHG

Significance Threshold for industrial projects where the SCAQMD is the lead agency (e.g.,

stationary source permit projects, rules, plans, etc.) of 10,000 Metric Tons (MT) CO2

equivalent/year CO2e. In September 2010, the SCAQMD CEQA Significance Thresholds GHG

Working Group released revisions which recommended a threshold of 3,000 MT CO2e for all land

use projects. This 3,000 MT/year recommendation has been used as a guideline for this analysis.

In the absence of an adopted numerical threshold of significance, project related GHG emissions

in excess of the guideline level are presumed to trigger a requirement for enhanced GHG reduction

at the project level.

PROJECT RELATED GHG EMISSIONS GENERATION Construction Activity GHG Emissions

The project is assumed to require less than two years construction. During project construction,

the CalEEMod2016.2.1 computer model predicts that the construction activities will generate the

annual CO2e emissions identified in Table 10.

SCAQMD GHG emissions policy from construction activities is to amortize emissions over a 30-

year lifetime. The amortized level is also provided. GHG impacts from construction are

considered individually less-than-significant.

Project Operational GHG Emissions

The input assumptions for operational GHG emissions calculations, and the GHG conversion from

consumption to annual regional CO2e emissions are summarized in the CalEEMod2013.2.2 output

files found in the appendix of this report.

The total operational and annualized construction emissions for the proposed project are identified

in Table 11.

Total project GHG emissions would be substantially below the proposed significance threshold of

3,000 MT suggested by the SCAQMD. Hence, the project would not result in generation of a

significant level of greenhouse gases.

CONSISTENCY WITH GHG PLANS, PROGRAMS AND POLICIES

The City of Azusa programs pertaining to greenhouse gas emissions are included in Natural

Environment Chapter of the City’s General Plan. These programs include the following, among

others:

AQ2 Land Use Patterns Encouraging Alternative Transportation

Encourage land use patterns that enable people to use alternative transportation methods such as

transit, walking, and cycling in their day-to-day activities. Expand opportunities for people to live

and work in close proximity.

AQ3 Promote Mixed-Use Development

Promote mixed-use development that provides commercial services close to residential zones and

employment centers, enabling citizens to walk or bicycle to services rather than drive. AQ5

Provide Sidewalks, Bicycle Lanes, and Bus Shelters

The City of Azusa has not yet developed a Greenhouse Gas Reduction Plan specific to new

residential development. The applicable GHG planning document is AB-32. As discussed above,

the project is not expected to result in a significant increase in GHG emissions. As a result, the

project results in GHG emissions below the recommended SCAQMD 3,000 ton threshold.

Therefore, the project would not conflict with any applicable plan, policy, or regulation to reduce

GHG emissions.
