Air Quality/Energy/GHG Technical Memo
This technical memorandum presents an analysis of the air quality, energy, and greenhouse gas (GHG)
impacts for the proposed Mission Trails Residential Development (project), located along the west side of
Mission Trail, south of Victorian Lane and north of Lemon Street, in the City of Lake Elsinore. The project
proposes the construction and operation of 191 single-family residences with common open space, a
community pool, and landscaping on a 16.98-acre site. The site is currently vacant.
The site was previously analyzed as part of buildout of the East Lake Specific Plan Amendment No.11 Final
Environmental Impact Report (2017), at the maximum allowable density of 18 dwelling units (DU) per acre.
The project proposes a density of 11.3 DU/acre, which is less than (and therefore within) with the previous
analysis.
To support the CEQA document for the project, this report analyzes the proposed project’s construction and
operational impacts to air quality (emission of criterial pollutants) emissions using the California Emissions
Estimator Model (CalEEMod v. 2022.1) land use emission model. Table 1 shows the estimated construction
schedule, which is expected to last about 11 months.

The following defaults were changed in the CalEEmod Emission Model for this analysis:
• The lot acreage and square feet for the single-family housing was changed to match the
architectural plans.
• Population was changed to match the City General Plan estimates for household size.
• Demolition was removed as the site is vacant.
• Architectural coating was increased due to the number of homes and buildings requiring coating.
• Vehicle Trip Lengths changed to be consistent with the vehicle miles traveled (VMT) analysis. (21.1
daily miles).
• Fireplaces and Wood Stoves removed as the project does not propose them. In addition, wood
burring stoves and fireplaces are prohibited by Southern California Air Quality Management
District (SCAQMD) rule 445.
Summary of Air Quality, Energy and GHG Impacts
Air Quality:
The project’s maximum daily emissions (regional and local) for construction and operation of the project
would not exceed SCAQMD’s regional thresholds of significance. In addition, all construction activities would
comply with applicable SCAQMD rules and regulations, including Rule 403 to minimize fugitive PM dust

emissions, Rule 445 preventing woodfire stoves, and Rule 1113 which allows only Low-Volatile Organic
Compounds (VOC) paints. Projects that do not exceed the regional thresholds are assumed to not have a
significant impact on a project level and cumulative level. Therefore, the proposed project would have less
than significant air quality impacts.
Energy:
The project’s energy consumption for construction does not have any unusual characteristics and is not less
efficient compared with other similar construction sites. The operation of the project is also similar to other
residential projects and would comply with Title 24 as well as all applicable City business and energy codes
and ordinances, including photovoltaic (PV) solar panels on the rooftop of each residence to offset the energy
demand.
GHG:
The proposed project’s GHG emissions of 2,552 MTCO2e per year and 4.1 MTCO2e per service population
are below the SCAQMD and CAP significance threshold of 3,000 MTCO2e per year and 6.6 MTCO2e per
service population for projects after 2020. Therefore, the project has a less then significant impact on GHG
emissions.
Air Quality Impact Tables
Regional Emissions
The SCAQMD has adopted maximum daily emission thresholds1 (pounds/day) for the criteria pollutants
during construction and operation of a project. While incremental regional air quality impacts of an
individual project are generally very small and difficult to measure, SCAQMDs regional maximum emission
thresholds set standards to reduce the burden of SCAQMD to attain and maintain ambient air quality
standards. The regional thresholds apply to the criteria pollutants mentioned above and can be found in
Table 2 and Table 3 along with the CalEEMod projects emissions. These emission thresholds include the
project emissions generated both from onsite sources (such as off-road construction equipment and fugitive
dust) and offsite sources (vehicle travel leaving and arriving to the site). As can be seen in Table 2 and Table
3, the project would have less then significant regional air quality impacts.

Local Emissions
Localized significance thresholds (LSTs) were also adopted by the SCAQMD due to project -related
construction or operational air emissions having the potential to exceed the state and national air quality
standards in the project vicinity, while not exceeding the regional emission significance thresholds adopted
by the SCAQMD. These thresholds set the maximum rates of daily construction or operational emissions from
a project site that would not exceed a national or State ambient air quality standard2. The differences
between regional thresholds and LSTs are as follows:
1. Regional thresholds include all sources of project construction and operational emissions generated
from onsite and offsite emission sources whereas the LSTs only consider the emissions generated from
onsite emission sources.
2. LSTs only apply to CO, NOx, PM10, and PM2.5, while regional thresholds include both ROG and SOx.
3. Regional Thresholds apply to emission sources located anywhere within the SCAQMD whereas the
LSTs are location dependent and also depend on the size of the project, and emission location
relative to the nearest sensitive receptor.
A sensitive receptor is defined as an individual who is most susceptible to negative health affects when
exposed to air pollutants including children, the elderly, and adults with chronic health issues. Such receptors
include residences, schools, elderly care centers, and hospitals. SCAQMD provides screening look up tables

(Appendix C of the SCAQMD 2008 Final Localized Significance Threshold Methodology)3 for projects that
disturb less than or equal to 5 acres in size in a day. These tables were created to easily determine if the
daily emissions of NOx, CO, PM10, and PM2.5 from a project could result in a significant impact to the local
air quality. The thresholds are determined by:
• Source receptor area (SRA), the geographic area within the SCAQMD that can act as both a source
of emissions and a receptor of emission impacts (project is located within SRA 25, Lake Elsinore),
• Size of the project,
• Distance to the nearest sensitive receptor.
The phase with the most ground disturbance would be the grading phase, which would grade 3 acres per
day. The Fact Sheet for Applying CalEEMod to Localized Significance Thresholds, prepared by SCAQMD,
2015, provides guidance on how to determine the appropriate site acreage size to utilize for LST analyses.
The Fact Sheet details that the maximum number of acres disturbed on the peak day of construction is
calculated from the construction equipment list utilized in the CalEEMod model, which identifies that crawler
tractors, graders, and rubber-tired dozers disturb 0.5-acre in an 8-hour day and scrapers disturb 1.0-acre
in an 8-hour day.

The thresholds were interpolated from the thresholds for 2 acres and 5 acre from Appendix C. Distance to
the nearest sensitive receptor also determines the emission thresholds. The sensitive receptors closest to the
project include residential homes east of the project boundary, about 34 meters (111 feet) from the property
line. The thresholds were interpolated from the thresholds for 25 meters and 50 meters. Table 4 shows the
thresholds and estimated maximum daily construction emissions for the proposed project. As seen in Table 5,
the proposed project has a less then significant localized construction air quality impact.

According to the SCAQMD LST methodology, LSTs apply to project stationary mobile sources. Projects that
involve mobile sources that spend long periods queuing and idling at a site, such as transfer facilities or
warehousing and distribution buildings, have the potential to exceed the operational localized significance
thresholds. The proposed project would operate 191 residential units, which do not involve vehicles idling
or queueing for long periods. Therefore, due to the lack of significant stationary source emissions, impacts
related to operational localized significance thresholds would be less than significant.
Conclusion
The project’s maximum daily emissions (regional and local) for construction and operation of the project
would not exceed SCAQMD’s regional thresholds of significance. In addition, all construction activities would
comply with applicable SCAQMD rules and regulations, including Rule 403 to minimize fugitive PM dust
emissions, Rule 445 preventing woodfire stoves, and Rule 1113 which allows only Low-Volatile Organic
Compounds (VOC) paints. Projects that do not exceed the regional thresholds are assumed to not have a
significant impact on a project level and cumulative level. Therefore, the proposed project would have less
than significant air quality impacts.
Additionally, the project will comply with the following mitigation measures (MMs) pursuant to the East Lake
Specific Plan Final EIR:
MM AQ-1: Prior to approval of each new implementing development project within the East Lake
Specific Plan, the applicant/developer shall demonstrate avoidance, to the extent possible, of significant
impacts on air quality from construction activities through implementation of regulatory requirements and
best management practices. Where project- specific analysis determines that air quality standards may be
exceeded, mitigation measures that shall reduce the emissions to within air quality standards or to the
greatest extent practicable shall be implemented. Project-specific analysis may be provided in the form of
an air quality technical report, study, or memorandum. The mitigation measures shall include but not be
limited to:
Dust Control
1. Apply soil stabilizers according to manufacturers’ specifications to inactive areas (previously graded
areas inactive for ten days or more).
2. Prepare a high wind dust control plan and implement plan elements and terminate soil disturbance
when winds (as instantaneous gust(s)) exceed 25 mph.
3. Stabilize previously disturbed areas if subsequent construction is delayed.
4. Water actively graded surfaces 3 times per day.
5. Cover all stock piles with tarps if left undisturbed for more than 72 hours.
6. Replace ground cover in disturbed areas as soon as feasible.
7. Provide water spray during loading and unloading of earthen materials.
8. Install wheel washers, shaker plates and gravel where vehicles enter and exit the construction site
onto paved roads or wash off trucks and any equipment leaving the site each trip.
9. All streets shall be swept at least once a day using SCAQMD Rule 1186 1186.1 certified street
sweepers or roadway washing trucks if visible soil materials are carried to adjacent streets
(recommend water sweepers with reclaimed water).
10. All trucks hauling dirt, sand, soil, or other loose materials are to be covered.
11. Appoint a construction relations officer to act as a community liaison concerning onsite construction
activity including resolution of issues related to PM10 generation.

12. Require 90-day low-NOX tune-ups for off-road equipment.
13. Limit allowable idling to 5 minutes for trucks and heavy equipment.
14. Utilize equipment whose engines are equipped with diesel oxidation catalysts if available.
15. Utilize diesel particulate filter on heavy equipment where feasible.
16. Utilize Tier 4 off-road construction equipment. If Tier 4 off-road construction equipment is not
available, require alternative fueled off-road equipment.
17. Configure construction parking to minimize traffic interference.
18. Use electricity from power poles rather than temporary diesel or gasoline power generators where
connections are available.
19. Provide temporary traffic controls when activities encroach on active roadways, such as a flag
person, during all phases of construction to maintain smooth traffic flow.
20. Schedule construction activities that affect traffic flow on the arterial system to off-peak hours to the
extent practicable.
21. Reroute construction trucks away from congested streets or sensitive receptor areas.
22. Provide dedicated turn lanes for movement of construction trucks and equipment on- and off-site.
23. Require the use of 2010 model year diesel haul trucks that conform to 2010 EPA truck standards or
newer diesel haul trucks (e.g., material delivery trucks and soil import/export), and if 2010 model
year or newer diesel haul trucks cannot be obtained, the City shall require use of trucks that meet
EPA 2007 model year NOx emissions requirements. Example verification includes making this
provision a part of the construction contractor’s bid package, construction contract, or hauling permit.
Project Applicability: MM AQ-1 is applicable to the proposed project and would be implemented as part
of the construction permitting process.
MM AQ-2: Prior to approval of each new implementing development project within the East Lake
Specific Plan that proposes new sensitive receptors and/or would be within 500 feet of sensitive receptors
shall conduct an evaluation of human health risks and/or Localized Significance Threshold (LST) analysis to
identify and reduce any potential health risks from construction and/or operation impacts to sensitive
receptors. Sensitive receptors include residential, schools, day care facilities, congregate care facilities,
hospitals, or other places of long-term residency. The thresholds to determine exposure to substantial
pollution concentrations are: A Maximum Individual Cancer Risk (MICR) of greater than ten (10) in one million.
For non-cancer risks, the threshold is a hazard index value greater than one (1). LST thresholds shall be those
recommended by SCAQMD. LST analysis may be provided in the form of an air quality technical report,
study, or memorandum. If the analysis demonstrates LST thresholds will not be exceeded, no additional
mitigation shall be required. If the analysis demonstrates exceedance during temporary construction activities
or long-term operations, additional mitigation measures shall be required through conditions of approval to
reduce impacts to below thresholds. Additional measures may include but not be limited to the use of one or
more of the following: reduced construction schedules, low-emitting construction equipment, particulate filters,
temporary or permanent use of setbacks, screening, buffers and building ventilation filters.
Project Applicability: MM AQ-2 is applicable to the proposed project, and as detailed in Table 4, the
proposed project would not exceed any LST thresholds and would therefore not require further mitigation.
MM AQ-3: Prior to issuance of a building permit for new implementing development projects within the
East Lake Specific Plan, the applicant shall demonstrate that the following measures to conserve energy have
been incorporated into building design:
1. Submit plans demonstrating that any new residential buildings achieve 15% energy efficiency
above 2019 Title 24 for projects after 2020.
2. Submit plans demonstrating that any new commercial buildings shall include the following green
building design features:
2.1. Low-E and ENERGY STAR windows where feasible;
2.2. High-efficiency lighting systems and incorporate advanced lighting controls, such as auto
shut-offs, timers, and motion sensors;
Mission Trails Residential Development
Air Quality/Energy/GHG Technical Memo
7
2.3. High R-value wall and ceiling insulation; and,
2.4. Use of fluorescent lighting and/or LED lighting.
3. Require acquisition of new ENERGY STAR qualified appliances and equipment.
4. Implement passive solar design strategies in new construction. Examples of passive solar strategies
include orienting building to enhance sun access, designing narrow structures, and incorporating
skylights and atria.
Project Applicability: MM AQ-3 is applicable to the proposed project and would be implemented as part
of the building permitting process.
MM AQ-4 Prior to issuance of a building permit for new commercial, multi-family residential and
mixed-use implementing development projects within the East Lake Specific Plan, the applicant shall
demonstrate on the landscaping plan that the following water and energy conservation measures have been
incorporated:
1. Participation in green waste collection and recycling programs for landscape maintenance with
designated green waste collection and storage areas and use of vendors that provide green waste
collection and recycling services during operation of future development project;
2. Use of landscaping with low water requirements in accordance with the City of Lake Elsinore’s Water
Efficient Landscape Requirements Ordinance (Lake Elsinore Municipal Code Chapter 19.08);
3. Planting of trees or vegetation to shade buildings and thus reduce heating/cooling demand.
Project Applicability: MM AQ-4 is not applicable to the proposed project because the project does not
include commercial, multi-family residential and mixed-uses. However, participation in green waste collection
and recycling programs for landscape maintenance, compliance with the City’s landscaping and water
efficiency requirements would be implemented as part of the building permitting process.
Energy
The State CEQA Guidelines do not have specific thresholds for Energy consumption. Rather, the question in
Appendix G: VI Energy (a) asks, “[Does the proposed project] Result in potentially significant environmental
impact due to wasteful, inefficient, or unnecessary consumption of energy resources during project
construction or operation?”. Therefore, for the purpose of this analysis, a significant impact would occur if:
• The Project design and/or location encourages wasteful, inefficient, and unnecessary consumption
of energy, especially fossil fuels such as coal, natural gas, and petroleum, as well as the use of fuel
by vehicles anticipated to travel to and from the project.
The following assumptions were used to calculate the energy consumption of the proposed project:
• The project’s construction and operational energy consumption would be provided by Southern
California Edison Company.
• Construction equipment fuel consumption derived from ARB Offroad2021 emission model
• Fuel Consumption from vehicle travel derived from ARB EMFAC2021 emission model
• Electrical and natural gas usage derived from the CalEEMod model
Construction
Electricity and Natural Gas Usage:
Due to the project size and the fact that construction is temporary, the electricity used would be substantially
less than that required for project operation and would have a negligible contribution to the project’s overall
energy consumption. The electric power used would be for as-necessary lighting and electronic equipment
such as computers inside temporary construction trailers. Natural gas is not anticipated to be needed for
construction activities. Any consumption of natural gas would be minor and negligible in comparison to the
operation of the proposed project.
Mission Trails Residential Development

Petroleum Fuel Usage:
The construction equipment associated with construction activities (off-road/heavy duty vehicles) would rely
on diesel fuel as would vendor and haul trucks involved in delivering building materials and removing the
demolition debris from the project site. Construction workers would travel to and from the project site
throughout the duration of construction, and for a conservative analysis it is assumed that construction workers
would travel in gasoline-powered passenger vehicles.
Table 6 shows the total fuel consumption and horsepower-hour data contained within the ARB OffRoad2021
emission model for specific types of diesel construction equipment. It should be noted that the total fuel
consumption is a conservative analysis and would likely overstate the amount of fuel usage, as specific
construction equipment is not expected to operate during the duration of the construction activity (i.e., crane).
Table 7 summarizes the project’s construction vehicle fuel usage based on vehicle miles traveled and fuel
usage factors contained in the ARB EMFAC2021. The trips included are worker vehicles, vendor vehicles, and
haul vehicles. Table 8 shows the overall fuel consumption for construction of the proposed project.

The operation of the proposed project would consume electricity, natural gas, and petroleum. The net energy
consumption can be found in Table 9 below. Electricity and natural gas consumption were found in the Annual
CalEEMod Output Sheets attached. The gasoline consumption rates utilize the same assumptions that were
used for the worker vehicles.

Conclusion
The proposed project has no unusual characteristics that would make the construction fuel and energy
consumption associated with construction of the project less efficient compared with other similar construction
sites throughout the state. The consumption would also be temporary and localized. Operation of the 191
single family residential units would comply with all the energy efficiency requirements under Title 24 and
all applicable City business and energy codes ordinances. Therefore, the construction and operation of the
project would result in a less than significant impact for inefficient, wasteful, or unnecessary energy use, and
no mitigation would be required.
Greenhouse Gas
SCAQMD has convened a Greenhouse Gas Emissions (GHG) CEQA Significance Threshold Working Group
to help lead agencies determine significance thresholds for GHG emissions when SCAQMD is not the lead
agency. The last working group was held September 2010 (Meeting No. 15)4 and proposed a tiered
approach, equivalent to the existing consistency determination requirements in CEQA Guidelines Sections
15064(h)(3), 15125(d), or 15152(a). The most recent proposal issued in Meeting No. 15 uses a tiered
approach, Tier 1 to Tier 5, to evaluate potential GHG impacts from various uses. The assessment of the
proposed project applies the Tier 3: Numerical Screening Thresholds approach. Tier three consists of
screening values in metric tons of carbon dioxide equivalent (MTCO2e) (converting other greenhouse gasses

to an equivalent impact of CO2). A project’s construction emissions are averaged over 30 years and are
added to the project’s operational emissions. If a project’s emissions are below one of the following screening
thresholds, then the project impact would be less than significant:
• Option 1: All land use types: 3,000 MTCO2e per year
• Option 2: Based on land use type: residential: 3,500 MTCO2e per year; commercial: 1,400
MTCO2e per year; or mixed use: 3,000 MT CO2e per year
Executive Order S-3-05’s year 2050 goal is the basis of SCAQMD’ draft Tier 3 screening level thresholds.
The objective of the Executive Order is to contribute to capping worldwide CO2 concentrations at 450 ppm,
stabilizing global climate change. Option 1 was used for this analysis; therefore, the GHG threshold used is
3,000 MTCO2e per year.
In addition to the SCAQMD threshold, the City of Lake Elsinore adopted the City of Lake Elsinore Climate
Action Plan (CAP) (December 2011). Within the CAP, the City adopted an efficiency threshold of 6.6
MTCO2e per service population (SP) by 2020 and 4.4 MTCO2e per SP by 2030. Therefore, in addition to
the 3,000 MTCO2e threshold, the Cities CAP threshold of 6.6 MTCO2e per SP was used.
The project’s construction GHG emissions are shown in Table 10 and the overall construction and operational
emissions are shown in Table 10 These emissions were calculated using the CalEEMod Model. The construction
emissions are amortized over 30 years. As shown in Table 11, the net GHG emissions are 2,552 MTCO2e
per year and 4.1 MTCO2e per SP, below the 3,000 MTCO2e per year and 6.6 MTCO2e per SP thresholds.
Therefore, the project would have a less than significant GHG impact.

MTCO2e per service population for projects after 2020. Therefore, the project has a less then significant
impact on GHG emissions.
Additionally, the project will comply with the following mitigation measures (MMs) from the East Lake
Specific Plan Final EIR:
MM GHG-1: Prior to issuance of a building permit for new implementing development projects within
the East Lake Specific Plan, the applicant shall be required to demonstrate compliance with the following:
1. Achieve 15% energy efficiency above 2016 Title 24, Part 6 for projects after 2018 and 5%
energy efficiency above 2016 Title 24 for projects after 2020.
2. Reduce indoor water consumption by 30% for projects after 2018 and 35% for projects after
2020 above baseline identified in 2016 Title 24, Part 11.
Project Applicability: MM GHG-1 is applicable to the proposed project and would be implemented as
part of the building permitting process.
