1.0 EXISTING AIR QUALITY
1.1 Project Description
The proposed project is requesting a Site Development Review and a new Tentative Tract Map
to develop a new Duplex and Townhome residential community consisting of 92 attached
homes consistent with the existing RM-6000 Zoning requirements and standards. The project
is located at 1244 Irvine Blvd., at corner of Mariners Drive and Rutland Road, Newport Beach,
CA (Exhibit 1). The project will demolish approximately 114 apartment units. The site is 5.77
acres.
This report focuses only on the potential air quality impacts associated with the construction of
this project.
2.0 POTENTIAL CONSTRUCTION IMPACTS
2.1 Thresholds of Significance
2.1.1 Regional Air Quality
In their "1993 CEQA Air Quality Handbook”, the SCAQMD has established significance
thresholds to assess the construction impact of project related air pollutant emissions. Table
1 presents these significance thresholds. A project with daily emission rates below these
thresholds are considered to have a less than significant effect on regional air quality. It should
be noted the thresholds recommended by the SCAQMD are very low and subject to
controversy. It is up to the individual lead agencies to determine if the SCAQMD thresholds
are appropriate for their projects.

2.1.2 Localized Significance Thresholds
As part of the SCAQMD’s environmental justice program, attention was focused on localized
effects of air quality. In accordance with Governing Board direction, SCAQMD staff developed
localized significance threshold (LST) methodology and mass rate look-up tables by Source
Receptor Area (SRA) that can be used to determine whether or not a project may generate
significant adverse localized air quality impacts. LSTs represent the maximum emissions from
a project that will not cause or contribute to an exceedance of the most stringent applicable
federal or state ambient air quality standard, and are developed based on the ambient
concentrations of that pollutant for each source receptor area. The LST methodology is
described in “Final Localized Significance Threshold Methodology” updated in 2009 by the
SCAQMD and is available at the SCAQMD website
(http://aqmd.gov/ceqa/handbook/LST/LST.html).
The LST mass rate look-up tables provided by the SCAQMD allow one to determine if the daily
emissions for proposed construction activities could result in significant local air quality
impacts. If the calculated on-site emissions for the proposed construction activities are below
the LST emission levels found on the LST mass rate look-up tables and no potentially significant
impacts are found to be associated with other environmental issues, then the proposed
construction activity is not significant for local air quality.
The LST mass rate look-up tables are applicable to the following pollutants only: oxides of
nitrogen (NOX), carbon monoxide (CO), particulate matter less than 10 microns in aerodynamic
diameter (PM10), and particulate matter less than 2.5 microns (PM2.5). LSTs are derived based
on the location of the activity (i.e., the source/receptor area); the emission rates of NOX, CO,
PM2.5 and PM10; and the distance to the nearest exposed individual.
The LST methodology presents mass emission rates for each SRA, project sizes of 1, 2, and 5
acres, and nearest receptor distances of 25, 50, 100, 200, and 500 meters. For project sizes
between the values given, or with receptors at distances between the given receptors, the
methodology uses linear interpolation to determine the thresholds. If receptors are within 25
meters of the site, the methodology document says that the threshold for the 25-meter
distance should be used.
The project is located in Source Receptor Area (SRA) 18. The nearest existing sensitive land
use are the residences south of the project site, and are about 70 feet (21 meters) from any
significant construction area. Therefore, the minimum recommended LST distance of 25
meters was used for the analysis. Table 2 summarizes the LSTs for construction for this project.
The thresholds listed in Table 2 are based on a 5-acre site and a 25 meter distance. A project
with daily emission rates below the thresholds during construction is considered to have a less
than significant effect on local air quality.

2.2 Construction Impacts
Temporary impacts can result from project construction activities. Air pollutants are emitted
by construction equipment and fugitive dust is generated during grading and construction.
Emissions during the phases of construction were calculated using the California Emissions
Estimator Model (CalEEMod version 2016.3.2). CalEEMod is a computer program developed
by the SCAQMD in conjunction with the California Air Resources Board (CARB). The model
calculates emissions for construction and operation of various projects. For on-road vehicular
emissions, the CalEEMod model utilizes the latest EMFAC emission rates that have also been
developed by CARB.
2.2.1 Regional Emissions
CalEEMod considers the following phases in its calculation of construction emissions;
demolition, site preparation, grading, building construction, paving, and painting. The
appropriate number of acres, number of units being demolished and construction, and other
key elements of the project were input into the CalEEMod to generate the estimate of
emissions. Since a construction schedule has not been developed, the defaults in the
CalEEMod were used and seem reasonable. It was assumed that the overlap between
construction phases would be minimal. However, building construction, paving, and painting
(architectural coating) might all occur at the same time, and therefore, the combination of these
three construction phases were considered together. No mitigation is assumed for this
analysis. The SCAQMD Rules and Regulations require that the site be watered three times per
day, and this requirement was included in the modeling. CalEEMod printouts are included in
the Appendix.
Table 3 presents the results of the total emissions calculations for the construction activities
discussed above. The highest construction emissions are presented below and represent a
worst-case scenario. The projected emissions are compared to the Significance Thresholds
described in Section 2.1.2. The CalEEMod printouts are included in the Appendix.

Exceed Threshold? No No No No No No
The projected construction emissions are all well below the significance thresholds established
by the SCAQMD. Therefore, there will be no regional air quality impacts due to construction.
2.2.2 Local Air Quality Impacts Due to Construction
The on-site construction emissions were calculated utilizing CalEEMod. The emissions
presented in Table 4 are those that would be emitted from activity within the project site. The
total on-site construction emissions are compared to the Localized Significance Thresholds
(LSTs) described in Section 2.1.2. Worksheets showing the emission calculations are presented
in the appendix.

None of the emissions will exceed the LST significance thresholds. Local air quality impacts
during construction will be less than significant.
2.2.3 Diesel Particulate Matter Emissions During Construction
In 1998, the California Air Resources Board (ARB) identified particulate matter from diesel-
fueled engines (Diesel Particulate Matter or DPM) as a Toxic Air Contaminant (TAC). It is
assumed that the majority of the heavy construction equipment utilized during construction
would be diesel fueled and emit DPM.
Impacts from toxic substances are related to cumulative exposure and are assessed over a 70-
year period. Cancer risk is expressed as the maximum number of new cases of cancer
projected to occur in a population of one million people due to exposure to the cancer-causing
substance over a 70-year lifetime (California Environmental Protection Agency, Office of
Environmental Health Hazard Assessment, Guide to Health Risk Assessment.) Grading for the
project, when the peak diesel exhaust emissions would occur, is expected to take less than 1
month with all construction expected to be completed in several months. Because of the
relatively short duration of construction compared to a 70-year lifespan, diesel emissions
resulting from the construction of the project, including truck traffic associated with the project,
are not expected to result in a significant impact.
3.0 MITIGATION MEASURES
3.1 Construction Impacts
No construction impacts will occur, and therefore, mitigation measures will not be required.
