CALIFORNIA 1.0 EXECUTIVE SUMMARY LSA Associates, Inc. (LSA) was retained by RRM Design Group (RRM) on behalf of the City of Carlsbad (City) to prepare an air quality study for the proposed Carisbad Joint First Responders Training Facility located in the City of Carisbad, Califomia. The air quality study provides a discussion of the proposed project, the physical setting of the project i area, and the regulatory framework for air quality. The report provides data on existing air quality, evaluates potential air quality impacts associated with the proposed project, and identifies feasible ' mitigation measures recommended for potentially significant impacts. Modeled air quality levels are J based upon vehicle data and project phasing trip generation provided by the applicant and peak-hour turn volumes generated for the proposed project in the project's traffic study (LSA, Traffic Circulation Analysis, June 3, 2008). Historical air quality data show that existing carbon monoxide (CO) levels for the project area and the general vicinity do not exceed either the State or federal ambient air quality standards. The project- related traffic would not result in any federal or State CO standards being exceeded. No significant impact on local CO levels would occur. Long-term operational emissions associated with the proposed project, including mobile sources for the whole region and on-site stationary sources, would not exceed daily emissions thresholds established by the San Diego County (County). No significant long-term air quality impact would occur. Compliance with the rules and regulations from the San Diego County Air Pollution Control District •m (SDCAPCD), the County and the Califomia Air Resources Board (ARB) during constmction will reduce construction-related air quality impacts from fugitive dust emissions and constmction equipment emissions. With mitigation, emissions of criteria pollutants would not exceed any County daily thresholds. No significant short-term air quality impacts would occur. The evaluation was prepared in conformance with appropriate standards, utilizing procedures and methodologies in the San Diego County Guidelines for Determining Significance and Report Format and Content Requirements (San Diego County Department of Planning and Land Use, March 19, 2007). Air quality data posted on the ARB and EPA web sites are included to document the local air quality environment.

The project is located at 2560 Orion Way as shown in Figure 1. Figure 2 shows the preferred conceptual site layout of the facility. The site plan is not final. The decision on the site arrangement remains to be determined, based on the City Planning Department's Conditional Use Permit Process. The facility will be limited to the area bounded by Orion Way and Orion Street, which is approximately 4.03 acres when considering the area inside the curb. The project includes four (4) major facilities, a Residential Bum Prop Facility, a Commercial Bum ^ (tower) Prop Facility, A Fire Administtation/Support Facility, and a Shooting Range/Classroom Facility. The two (2) Bum Prop facilities will not have mechanical work, only plumbing and m electrical. They will be used by both Fire and Police in training activities. The Fire Administration/Classroom Facility includes space for the Fire Department's administration, weight room, break room, restrooms, showers, and lockers. The Shooting Range/Classroom Facility includes space for offices, storage rooms, special weapons and ammunition rooms, dividable classroom, restrooms, and two indoor Shooting Ranges (25 yard and 100 yard).

CALIFORNIA 3.0 SETTING ^ 3.1 REGIONAL AIR QUALITY d The project site is located in the City of Carlsbad, an area within the San Diego County Air Basin (Basin). Air quality regulation in the Basin is administered by the SDCAPCD, a regional agency 1 created for the Basin. The Basin climate is determined by its terrain and geographical location. The climate of the Basin is characterized by warm, dry summers and mild, wet winters. One of the main determinants of the climatology is the Pacific High. In the summer, this pressure center is located well to the north, causing storm tracks to be directed north of Califomia. This high-pressure cell maintains clear skies for much of the year. When the Pacific High moves southward during the winter, this pattem changes, and low-pressure storms are brought into the region, causing widespread precipitation. The Basin has a mild coastal climate and is 100 miles south of Los Angeles in California's southwest comer next to Mexico. People and air pollution emissions are concentrated near the Pacific Ocean d coast in San Diego. Summers are hot inland from the ocean. Although air quality in the Basin can be impacted by transport from the South Coast Air Basin to the north, local emission can also result in •"I violations of the State ozone standard. Prevailing daytime winds carry pollution from San Diego and Mi El Cajon toward the east. The Basin is also impacted by Tijuana, a Mexican city of 1.2 million people lying directly south of San Diego. The air over San Diego and Tijuana is one single mass, and both mi cities affect each other. The annual average temperature varies little throughout the Basin, ranging from the low to middle 70s, measured in degrees Fahrenheit. With a more pronounced oceanic influence, coastal areas show less variability in annual minimum and maximum temperatures than inland areas. The climatological station closest to the site that currently monitors temperature is the Oceanside Marina station. The annual average maximum temperature recorded for the last 50 years at this station is 68.0°F, and the annual average minimum is 53.1°F. January is typically the coldest month in this area of the Basin. The majority of annual rainfall in the Basin occurs between November and April. Summer rainfall is minimal and generally limited to scattered thundershowers in coastal regions. Average rainfall * measured at the Oceanside Marina station for the last 50 years varied from 2.14 inches in February to 0.40 inch or less between May and October, with an average annual total of 10.31 inches. m IH The vertical dispersion of air pollutants in the Basin is hampered by the presence of persistent temperature inversions. The subsidence inversions within the Basin generally occur during the warmer months (May through October) as descending air associated with the Pacific high-pressure cell meets cool marine air. Within the Basin, the inversion layer is approximately 2,000 feet (610 m) 1 Westem Regional Climatic Center at web site www.wrcc.dri.edu. accessed June 12, 2008 li P;\RDG0803 - Carlsbad First Responders FacililyVAir QualityVAir Quality.doc «O7/01/08» LSA ASSOCIATES INC A I R QUALITY ANALYSIS iUNF 200(1 CARLSBAD JOINT FIRST RESPONDERS TRAINING FACILITY CITY OF CARLSBAD, CALIFORNIA 1 J "1 J A 5 AMSL during the months of May through October. During the winter months (November through April), the temperature inversion rises to approximately 3,000 feet (914 m) AMSL. Inversion layers are important elements of local air quality because they inhibit the dispersion of pollutants, thus resulting in a temporary degradation of air quality. On days without inversions, or on days of winds averaging over 15 mph, smog potential is greatly reduced with the Basin. The combination of stagnant wind conditions and low inversions produces the greatest pollutant concentrations. On days of no inversion or high wind speeds, ambient air pollutant concentrations are the lowest. During periods of low inversions and low wind speeds, air pollutants generated in urbanized areas are transported inland. In the winter, the greatest pollution problems are CO and oxides of nitrogen (NOx) because of extremely low inversions and air stagnation during the night and eariy moming hours. In the summer, the longer daylight hours and the brighter sunshine combine to cause a reaction ^ between hydrocarbons and NOx to form photochemical smog. ^ 3.2 LOCAL AIR QUALITY The proposed site is located within SDCAPCD jurisdiction. The SDCAPCD maintains ambient air quality monitoring stations throughout the Basin. The air quality monitoring station closest to the site *<• is the Camp Pendleton Station, monitoring only ozone (O3) and nitrogen dioxide (NO2). The Escondido-E Valley Parkway station monitors all the criteria pollutants except sulfur dioxide (SO2). The closest station monitoring SO2 is in San Diego City. While this data may not be representative of ^ the project site, it is reported here for completeness. The criteria pollutants monitored at these stations' are illustrated in Table A. CO, NO2, and SO2 levels have not exceeded State and federal standards in the past three years. O3, particulate matter less than 10 microns in diameter (PMio) and ^ particulate matter less than 2.5 microns in diameter (PM2.5) concentrations occasionally exceed their respective State and federal standards. 3.3 REGULATORY SETTINGS * 3.3.1 Federal Regulations/Standards " Pursuant to the federal Clean Air Act (CAA) of 1970, the U.S. Environmental Protection Agency ^ (EPA) established national ambient air quality standards (NAAQS). The NAAQS were established for six major pollutants, termed "criteria" pollutants. Criteria pollutants are defined as those pollutants * for which the federal and State govemments have established ambient air quality standards, or ^ criteria, for outdoor concentrations in order to protect public health. * The NAAQS are two tiered: primary, to protect public health; and secondary, to prevent degradation of the environment (e.g., impairment of visibility, damage to vegetation and property). The six criteria " pollutants are O3, CO, PMio, NO2, SO2, and lead (Pb). The primary standards for these pollutants are Mf shown in Table B, and Table C lists the primary health risks and sources of common air pollutants. m m California Air Resources Board and U.S. EPA, 2008.

CALIFORNIA ,^ Footnotes: ' Califomia standards for ozone; carbon monoxide (except Lake Tahoe); sulfur dioxide (I and 24 hour); nitrogen dioxide; suspended particulate matter, PMio; and visibility reducing particles are values that are not to be exceeded. All others are not to be equaled or exceeded. Califomia ambient air quality standards are listed in the Table of Standards in Section 70200 of Title 17 of the Califomia Code of Regulations. s-i - National standards (other than ozone, paniculate matter, and those based on annual averages or 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 in a year, averaged over 3 years, is equal to or less than the standard. For PMio, the 24-hour standard is attained when the expected number of days per calendar year with a 24-hour average concentration above 150 ^g/m is *• equal to or less than I. For PM2,5, the 24-hour standard is attained when 98 percent of the daily concentrations, averaged over 3 years, are equal to or less than the standard. Contact U.S. EPA for further clarification and current H federal policies. ^ ^ 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. * Any equivalent procedure that can be shown to the satisfaction of the ARB to give equivalent results at or near the level of the air quality standard may be used. ^ ^ National Primary Standards: The levels of air quality necessary, with an adequate margin of safety to protect the public ^ health. National Secondary Standards: The levels of air quality necessary to protect the public welfare from any known or m anticipated adverse effects of a pollutant. ^ Reference method as described by the EPA. An "equivalent method" of measurement may be used but must have a "consistent relationship to the reference method" and must be approved by the EPA. The ARB 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. m m m m m m m m m P:\RDG0803 - Carlsbad First Responders Facility\Air QualityVAir Quality,doc «07/01/08» LSA ASSOCIATES.INC.

Because the concentration standards were set at a level that protects public health with an adequate margin of safety (EPA), these health effects will not occur unless the standards are exceeded by a large margin or for a prolonged period. State AAQS are more stringent than federal AAQS. Among the pollutants, O3 and particulate matter (PM2.5 and PMio) are considered regional pollutants, while the others have more localized effects. Data collected at permanent monitoring stations are used by the EPA to classify regions as "attainment" or "nonattainment," depending on whether the regions met the requirements stated in the primary NAAQS. Nonattainment areas are imposed with additional restrictions as required by the EPA. The CAA Amendments designated the Basin as "extreme" for O3, requiring attainment with the federal O3 standard by 2010; "serious" for CO, requiring attainment of federal CO standards by 2000; and "serious" for PMio, requiring attainment with federal standards by 2001. The EPA has designated the San Diego Association of Govemments (SANDAG) as the Metropolitan Planning Organization (MPO) responsible for ensuring compliance with the requirements of the CAA. m m P:\RE>G0803 - Carlsbad First Responders Facilily\Air QualilyVAir Quality,doc «07/01/08» 10 J''U^E^^7«'''^^^'• QUALITY ANALYSIS •"^ " CARLSBAD JOINT FIRST RESPONDERS TRAINING FACILITY ^ . CITY OF CARLSBAD. CALIFORNIA I I I 1. ir fa IT" MP m m m m The EPA established new national air quality standards for ground-level O3 and fine particulate matter in 1997. On May 14, 1999, the Court of Appeals for the District of Columbia Circuit issued a decision ruling that the CAA, as applied in setting the new public health standards for O3 and particulate matter, was unconstitutional as an improper delegation of legislative authority to the EPA. On February 27, 2001, the U.S. Supreme Court upheld the way the govemment sets air quality standards under the CAA. The Court unanimously rejected industry arguments that the EPA must consider financial cost as well as health benefits in writing standards. The justices also rejected arguments that the EPA took too much lawmaking power from Congress when it set tougher standards for O3 and soot in 1997. Nevertheless, the Court threw out the EPA's policy for implementing new O3 rules, saying that the agency ignored a section of the law that restricts its decision-making authority. It ordered the agency to come up with a more "reasonable" interpretation of the law. The EPA issued the final 8-hour O3 nonattainment designations/boundaries on April 15, 2004. States will be provided three years, to April 2007, to develop 8-hour O3 State Implementation Plans (SIPs) following the final designations. States will need to demonstrate conformity by April 15, 2005, in 8-hour O3 nonattainment areas, given the one-year grace period following the final designations. Various areas in the State of Califomia have different attainment dates based on their corresponding classification. The EPA revoked the 1-hour O3 standard on June 15, 2005. The EPA issued the final PM2.5 implementation rule in fall 2004. The EPA issued final designations on December 14, 2004. The EPA lowered the 24-hour PM2.5 standard from 65 to 35 ^g/m^ and revoked the annual PMio standard on December 17, 2006. 3.3.2 State Regulations/Standards The State of Califomia began to set Califomia ambient air quality standards (CAAQS) in 1969 under the mandate of the Mulford-Carrell Act. The CAAQS are generally more stringent than the NAAQS. In addition to the six criteria pollutants covered by the NAAQS, there are CAAQS standards for sulfates, hydrogen sulfide, vinyl chloride, and visibility reducing particles. These standards are also listed in Table B. Originally, there were no attainment deadlines for the CAAQS. However, the Califomia Clean Air Act (CCAA) of 1988 provided a time frame and a planning stmcture to promote their attainment. The CCAA required nonattainment areas in the State to prepare attainment plans and proposed to classify each such area on the basis of the submitted plan, as follows: moderate, if CAAQS attainment could not occur before December 31, 1994; serious, if CAAQS attainment could not occur before December 31, 1997; and severe, if CAAQS attainment could not be conclusively demonstrated at all. Hi The attainment plans are required to achieve a minimum 5 percent annual reduction in the emissions of nonattainment pollutants unless all feasible measures have been implemented. The Basin currently meets the federal standards for all criteria pollutants except O3 and PM2.5 and meets State standards ^ for all criteria pollutants except O3, PM,o, and PM2.5- The Basin air quality attainment status is shown in Table D.

Ozone (smog) is formed by photochemical reactions between oxides of nitrogen and reactive organic gases rather than being directly emitted. Ozone is a pungent, colorless gas typical of Southem Califomia smog. Elevated ozone concentrations result in reduced lung function, particularly during vigorous physical activity. This health problem is particularly acute in sensitive receptors such as the sick, the elderly, and young children. Ozone levels peak during summer and early fall. The Basin completed 3 years within the Federal I-hour O3 standard on November 15, 2001, becoming eligible for redesignation as an attainment area. Formal redesignation by the EPA as an O3 attainment area occurred on July 28, 2003, and a maintenance plan was approved. On April 15, 2004, the EPA issued the initial designations for the 8-hour O3 standard, and the Basin is classified as "basic" nonattainment. Basic is the least severe of the six degrees of O3 nonattainment. The SDAPCD must submit an air quality plan to the EPA in 2007; the plan must demonstrate how the 8-hour O3 standard will be attained by 2009. The Basin is currently classified as a State "serious" O3 nonattainment area. Carbon Monoxide. Carbon monoxide (CO) is formed by the incomplete combustion of fossil fuels, almost entirely from automobiles. It is a colorless, odorless gas that can cause dizziness, fatigue, and impairments to central nervous system functions. The entire Basin is in attainment for the State and federal standards for CO. Nitrogen Oxides. Nitrogen dioxide (NO2), a reddish brown gas, and nitric oxide (NO), a colorless, odorless gas, are formed from fuel combustion under high temperature or pressure. These compounds are referred to as nitrogen oxides, or NOx. NOx is a primary component of the photochemical smog il P:\RDG0803 - Carlsbad First Responders Facilily\Air Qiialily\Air Quality.doc «07/01/08» 12 ''NE'IOO"/'"^''- QfJALITY ANALYSIS JUNK iUtiS CARLSBAD JOINT FIRST RESPONDERS TRAINING FACILITY CITY OF CARLSBAD. CALIFORNIA reaction. It also contributes to other pollution problems, including a high concentration of fine particulate matter, poor visibility, and acid deposition (i.e., acid rain). NO2 deci^ases lung function and may reduce resistance to infection. The entire Basin has not exceeded both federal and State standards for nitrogen dioxide in the past 5 years with published monitoring data. It is designated as an attainment area under the State and federal standards. Sulfur Dioxide. Sulfur dioxide (SO2) is a colorless irritating gas formed primarily from incomplete combustion of fuels containing sulfur. Industrial facilities also contribute to gaseous SO2 levels. SO2 irritates the respiratory tract, can injure lung tissue when combined with fine particulate matter, and reduces visibility and the level of sunlight. The entire Basin is in attainment with both federal and State sulfur dioxide standards. Lead. Lead is found in old paints and coatings, plumbing, and a variety of other materials. Once in the blood stream, lead can cause damage to the brain, nervous system, and other body systems. Children are highly susceptible to the effects of lead. The entire Basin is in attainment for the federal and State standards for lead. Particulate Matter. Particulate matter is the term used for a mixture of solid particles and liquid droplets found in the air. Coarse particles (all particles less than or equal to 10 micrometers in diameter, or PMio) derive from a variety of sources, including windblown dust and grinding ^ operations. Fuel combustion and resultant exhaust from power plants and diesel buses and tmcks are primarily responsible for fine particle (less than 2.5 microns in diameter, or PM2.5) levels. Fine r particles can also be formed in the atmosphere through chemical reactions. Coarse particles (PMio) ^ can accumulate in the respiratory system and aggravate health problems such as asthma. The EPA's scientific review concluded that fine particles (PM2.5), which penetrate deeply into the lungs, are more likely than coarse particles to contribute to the health effects listed in a number of recently published community epidemiological studies at concentrations that extend well below those allowed by the current PMjo standards. These health effects include premature death and increased hospital admissions and emergency room visits (primarily the elderly and individuals with cardiopulmonary disease); increased respiratory symptoms and disease (children and individuals with cardiopulmonary disease such as asthma); decreased lung functions (particularly in children and individuals with asthma); and alterations in lung tissue and structure and in respiratory tract defense mechanisms. The entire Basin is a nonattainment area for the State PMio and PM2.5Standards and in ^ attainment/unclassified for federal PM]o and PM2,5Standards. il m m m m m Reactive Organic Compounds. Reactive organic compounds (ROCs; also known as reactive organic gases [ROGs] and volatile organic compounds [VOCs]) are formed from the combustion of fuels and the evaporation of organic solvents. ROCs are not defined as criteria pollutants, but are a prime component of the photochemical smog reaction. Consequently, ROC accumulates in the atmosphere more quickly during the winter when sunlight is limited and photochemical reactions are slower. 3.4 REGIONAL AIR QUALITY PLANNING FRAMEWORK The 1976 Lewis Air Quality Management Act established the SDCAPCD and other air districts throughout the State. The CAA Amendments of 1977 required that each state adopt an implementation plan outlining pollution control measures to attain the federal standards in nonattainment areas of the state.

CALIFORNIA The ARB coordinates and oversees both State and federal air pollution control programs in Califomia. The ARB oversees activities of local air quality management agencies and is responsible for incorporating air quality management plans for local air basins into a State Implementation Plan (SIP) for EPA approval. The ARB maintains air quality monitoring stations throughout the State in conjunction with local air districts. Data collected at these stations are used by ARB to classify air basins as "attainment" or "nonattainment" with respect to each pollutant and to monitor progress in attaining air quality standards. The ARB has divided the State into 15 air basins. Significant authority for air quality control within them has been given to local air districts that regulate stationary source emissions and develop local nonattainment plans. The CCAA provides the SDCAPCD with the authority to manage transportation activities at indirect sources and regulate stationary source emissions. Indirect sources of pollution are generated when minor sources collectively emit a substantial amount of pollution. An example of this would be the motor vehicles at an intersection, a ' mall, and on highways. As a State agency, the ARB regulates motor vehicles and fuels for their a emissions. n 3.4.1 Regional Air Quality Strategy The SDAPCD is the agency responsible for protecting the public health and welfare through the administration of Federal and State air quality laws and policies within the Basin. Included in the SDAPCD's tasks are the monitoring of air pollution, the preparation of the San Diego County portion of the SIP, and the promulgation of Rules and Regulations. The SIP includes strategies and tactics to be used to attain and maintain acceptable air quality in the county; this list of strategies is called the iU Regional Air Quality Strategies (RAQS). SDAPCD regulations require that any equipment that emits or controls air contaminants be permitted (Permit to Construct or Permit to Operate) prior to w construction, installation, or operation. The SDAPCD is responsible for review of applications and for the approval and issuance of these permits. ^ The current RAQS for the Basin is the 2004 Triennial Revision of the RAQS (2004 RAQS) which is an update of the 2001 RAQS. The 2004 RAQS employ up-to-date science and analytical tools and incorporate a comprehensive strategy aimed at controlling pollution from all sources, including stationary sources, on-road and off-road mobile sources, and area sources. The 2004 RAQS contain an expeditious schedule for adopting every feasible emission control measure under the SDAPCD's purview to comply with the NAAQS and CAAQS O3 standards. 3.5 GLOBAL WARMING Global warming is the observed increase in the average temperature of the earth's atmosphere and oceans in recent decades. The earth's average near-surface atmospheric temperature rose 0.6 ± 0.2°Celsius (C) (1.1 ± 0.4Tahrenheit [F]) in the 20th Century. The prevailing scientific opinion on climate change is that "most of the warming observed over the last 50 years is attributable to human activities."

They are released by the burning of fossil fuels, land clearing, and agriculture, etc., and lead to an increase in the GHG effect. GHGs are present in the atmosphere naturally, released by natural sources, or formed from secondary reactions taking place in the atmosphere. They include CO2, methane, nitrous oxide, and O3. In the last 200 years, substantial quantities of GHGs have been released into the atmosphere. These extra emissions are increasing GHG concentrations in the atmosphere, enhancing the natural greenhouse effect, which is believed to be causing global warming. While man-made GHGs include CO2, methane, and nitrous oxide, some (like chlorofluorocarbons [CFCs]) are completely new to the atmosphere. Natural sources of carbon dioxide include the respiration (breathing) of animals and plants and evaporation from the oceans. Together, these natural sources release approximately 150 billion tons of CO2 each year, far outweighing the 7 billion tons of man-made emissions from fossil fuel burning, waste incineration, deforestation, and cement manufacture. Nevertheless, natural removal processes such as photosynthesis by land and ocean-dwelling plant species cannot keep pace with this extra input of man-made CO2, and consequently the gas is building up in the atmosphere. Methane is produced when organic matter decomposes in environments lacking sufficient oxygen. Natural sources include wetlands, termites, and oceans. Man-made sources include the mining and burning of fossil fuels; digestive processes in ruminant animals such as cattle; rice paddies; and the burying of waste in landfills. Total annual emissions of methane are approximately 500 million tons, with man-made emissions accounting for the majority. As for CO2, the major removal process of atmospheric methane—chemical breakdown in the atmosphere—cannot keep pace with source emissions, and methane concentrations in the atmosphere are increasing.

CALIFORNIA m m m m m 4.0 METHODOLOGY A number of modeling tools are available to assess air quality impacts of projects. In addition, the County has created guidelines and requirements to conduct air quality analysis. The County's'current guidelines, Guidelines for Determining Significance and Report Format and Content Requirements, were adhered to in the assessment of air quality impacts for the proposed project. The URBEMIS2007 model was used to estimate project-related mobile and stationary source emissions in this air quality assessment. The air quality assessment includes estimating emissions associated with short-term construction of the proposed project. Localized air quality impacts (i.e., higher CO concentrations [CO hot spots] near intersections or roadway segments in the project vicinity) would be small and less than significant due to the generally low ambient CO concentrations in the project area. The net increase in pollutant emissions determines the significance and impact on regional air quality as a result of the proposed project. The results also allow the local govemment to determine whether the proposed project will deter the region from achieving the goal of reducing pollutants in accordance with the AQMP in order to comply with federal and State AAQS. ^ 4.1 THRESHOLDS OF SIGNIFICANCE To evaluate a project's potential impacts to air quality, a set of criteria was used. The criteria include daily emissions thresholds, compliance with State and national air quality standards, and conformity with the existing State Implementation Plan (SIP) or consistency with the current air quality plans. The SDAPCD has not established guidelines or emissions thresholds for Califomia Environmental ^ Quality Act (CEQA) review purposes. Therefore, the following thresholds established in the County of San Diego Guidelines for Determining Significance (March 2007) were used in this document to ^ determine whether or not a significant impact will occur: * • 75 pounds per day (lbs/day) of VOC IT • 250 lbs/day of NOx •i • 100 lbs/day of PMio _ • 55 lbs/day of PM2.5 Local Microscale Concentration Standards. The significance of localized project impacts under CEQA depends on whether ambient CO levels in the vicinity of the project are above or below State and federal CO standards. If ambient levels are below the standards, a project is considered to have a significant impact if project emissions result in an exceedance of one or more of these standards. If ambient levels already exceed a State or federal standard, project emissions are considered significant if they increase I-hour CO concentrations by 1.0 part per million (ppm) or more or 8-hour CO P:\RDG0803 - Carlsbad First Responders FacilityVAir QualityVAir Quality,doc "07/0i/08» 16 LSA ASSOCIATES.

The following are applicable local emission concentration standards for CO: • Califomia State 1-hour CO standard of 20.0 ppm • Califomia State 8-hour CO standard of 9.0 ppm 4.L2 Global Warming Global climate change may result in significant adverse effects to the environment that will be experienced worldwide, with some specific effects felt in Califomia. AB 32 requites statewide GHG emissions reductions to 1990 levels by 2020. Though these statewide reductions are now mandated by law, no generally applicable GHG emission threshold has yet been established, and guidance on global climate change analysis in CEQA documents will not be available until mid-2009. State CEQA Guidelines Section 15064(b) provides that the "determination of whether a project may have a significant effect on the environment calls for careful judgment on the part of the public agency involved, based to the extent possible on scientific and factual data," and, further, that an "ironclad definition of significant effect is not always possible because the significance of an activity may vary with the setting." The State CEQA Guidelines further indicate that even when thresholds are established, they may include "identifiable quantitative, qualitative or performance level of a A. particular environmental effect." (State CEQA Guidelines, Section 15064.7) r Some suggest that a zero emissions threshold would be appropriate in a climate change analysis; however, most believe that this would stop all progress and interfere with the ability of the economy to function. Further, prior CEQA case law makes clear that the "one additional molecule" rule is not IP consistent with CEQA (Communities for a Better Environment v. Califomia Resources Agency, 103 1^ Cal. App. 4th 98 [2002]). Such a mie also appears inconsistent with the State's approach to mitigation of climate change impacts. AB 32 does not prohibit all new GHG emissions; rather, it requires a reduction in statewide emissions to a given level. Thus, AB 32 recognizes that GHG emissions will continue to occur. I I IL f Ml m m m m. The Califomia Air Pollution Control Officers Association (CAPCOA) recently published a White Paper (January 2008) that explored several options for setting numeric, non-zero thresholds. The White Paper acknowledges medium to high uncertainty as to each potential numeric threshold due to the uncertainty associated with the effectiveness of AB 32 implementation overall, the new character of GHG reduction strategies on a project basis, the immaturity of GHG reduction technologies or infrastructure (such as widespread biodiesel availability), and the uncertainty of GHG reduction effectiveness of certain technologies (such as scientific debate li conceming the relative lifecycle GHG emissions of certain biofuels, for example). When applied to residential examples, the thresholds discussed would range from approximately 50 single-family dwelling units to 2,600 residential units as screening thresholds; commercial thresholds would rely on square footage. Application of those thresholds, however, may first require enactment of a specific Climate Action Plan in a General Plan or other large-scale policy document. Based on the above, none of the potential numeric thresholds would be appropriate for application to this project. Thus, for the purposes of analyzing this project, and consistent with one of the CAPCOA's P:\RIXJ0803 - Carlsbad First Responders Facilily\Air QnalilyXAir Quality.doc «07/01/08» 17 JU^E^2««r«'''*^''' QUALITY ANALYSIS jupit iv<js CARLSBAD JOINT FIRST RESPONDERS TRAINING FACILITY — ^ CITY OF CARLSBAD, CALIFORNIA w m w w m m m m m m identified approaches to climate change analysis, the potential climate change impacts will be analyzed without setting a specific threshold. Climate change is a global environmental problem; therefore, this study addresses climate change as a cumulative impact. To the extent possible, this study assesses potential sources of GHG emissions from the project and quantifies those emissions. Bearing in mind that CEQA does not require "perfection" but instead "adequacy, completeness, and a good faith effort at full disclosure," the analysis in this report is based on methodologies and information available at the time the study was prepared. Estimation of GHG emissions in the future does not account for changes in technology that may reduce such emissions; therefore, the estimates are based on past performance and represent a scenario that is worse than that which is likely to be encountered. Additionally, as explained in greater detail below, many uncertainties exist regarding the precise relationship between specific levels of GHG emissions and the ultimate impact on global climate. Significant uncertainties also exist regarding the reduction potential of potential mitigation strategies. Thus, while information is presented below to assist the public and the City's decision makers in understanding the project's potential contribution to global climate change impacts, the information available to the City is not sufficiently detailed to allow a direct comparison between particular project characteristics and particular climate change impacts, or between any particular proposed mitigation measure and any reduction in climate change impacts. Because no applicable numeric thresholds have yet been defined, and because the precise causal link between an individual project's emissions and global climate change has not been developed, this study also identifies qualitative factors to determine whether this project's emissions should be considered "cumulatively considerable." Some of those qualitative factors compare the proposed project to potential "business as usual" conditions. Such comparison is appropriate in the case of this climate change analysis because the statewide GHG reduction strategy involves reducing future emissions compared to future emissions under a "business as usual" scenario. Until the City or other regulatory agency devises a generally applicable climate change threshold, the analysis used in this study may or may not be applicable to other City projects.

CALIFORNIA 5.0 IMPACTS I i I n »" iL i* iki r Air pollutant emissions associated with the project would occur over the short term from constmction activities, such as fugitive dust from site preparation and grading, and emissions from equipment exhaust. There would be long-term regional emissions associated with project-related vehicular trips and onsite emissions from training operations. Long-term local CO emissions at intersections in the project vicinity would not be significantly affected by project-related traffic. Long-term stationary source emissions would occur due to energy consumption, such as electricity usage, by the proposed land uses. 5.1 CONSTRUCTION IMPACTS 5.L1 Equipment Exhausts and Related Construction Activities Constmction activities produce combustion emissions from various sources such as site grading, utility engines, on-site heavy-duty construction vehicles, equipment hauling materials to and from the site, asphalt paving, and motor vehicles transporting the constmction crew. Exhaust emissions from constmction activities envisioned on site would vary daily as constmction activity levels change. The use of constmction equipment on site would result in localized exhaust emissions. Preliminary construction plans include 7900 cy of cut, 4500 cy of fill, and shrinkage of 3000 cy, resulting in a net 400 cy export. This does not include remedial, which will be about 25,000 cy (i.e. the soils report calls for about the first 4 feet of soil to be removed and recompacted) The ARB URBEMIS2007 model was used to calculate the constmction emissions. The analysis divides the constmction process into four non-overiapping phases, as shown in Table G. The details of the construction schedule are not yet determined. Table G lists emissions from a typical set of equipment operating in each of the constmction phases. It shows that with all mitigation measures implemented, construction equipment/vehicle emissions of criteria pollutants would all remain below the County emission thresholds. Details of the equipment inventory, emission factors and other assumptions are included in Appendix A.

Dust generated during construction varies substantially on a project-by-project basis, depending on the level of activity, the specific operations, and weather conditions at the time of constmction. Construction emissions can vary greaUy depending on the level of activity, the specific operations taking place, the equipment being operated, local soils, weather conditions, and other factors. There are a number of feasible control measures that can be reasonably implemented to reduce PM|o emissions from construction significantly. Table G lists total construction emissions (fugitive-dust emissions and constmction-equipment exhausts); the table shows that during all construction phases, daily total constmction emissions with mitigation measures would be below the daily thresholds established by the County. 5.1.3 Architectural Coatings Architectural coatings contain VOCs that are similar to ROCs and are part of the O3 precursors. At this stage of project planning, no detailed architectural coatings information is available. Table G shows the expected emissions from architectural coatings of no more than 20 pounds per day. These emissions would occur after grading activities, near the end of the constmction phase. Therefore, this VOC emission is the principal air emission and exceeds the County VOC threshold of 75 lbs/day. 5.1.4 Odors Heavy-duty equipment in the project area during constmction would emit odors. However, the constmction activity would be short-term and would cease to occur after individual construction is completed. No other sources of objectionable odors have been identified for the proposed project, and no mitigation measures are required. 5.2 LONG-TERM PROJECT-RELATED EMISSIONS IMPACTS Long-term air emission impacts are those associated with stationary sources and mobile sources involving any project-related change. The URBEMIS2007 model was used to calculate these emissions. The model was set to reflect the State parameters for 2009 and reflected all applicable regional default assumptions. The emission factors used by URBEMIS2007 are from the ARB approved EMFAC2007 model. Although project-specific variables may be used, regional defaults tend to be the most conservative and acceptable when evaluating regional impacts. This computer model projects emissions rates for motor vehicles based on the year of analysis, a projected vehicle fleet mix, projected vehicle speeds, whether these emissions are projected to occur during the summer or the winter months, and other factors. Assumptions used in preparing the model analysis were consistent with those recommended in the San Diego County Guidelines for Determining Significance and Report Format and Content Requirements. » The proposed training facility area source emissions include the combustion of natural gas for heating il and the use of landscape maintenance equipment.

No No No No There will be additional emissions from the training exercises and firing range beyond what the URBEMIS2007 model includes. The training exercises use smoke and fire; they are designed to be realistic while not exposing the trainees to unnecessary hazards. The smoke generator units are standard theatrical smoke generators using a mineral oil as basis for the creation of smoke through a heating element. These are non-toxic in nature. Similar uses for the same type units are concert events, amusement parks and various Halloween venues. The most common training use will be to leave the building sealed up, start the smoke units to create an environment of about 12-18 inches in visibility before the firefighters enter. This will take anywhere from 7-10 minutes. At that point, the machines provide momentary bursts at regular intervals to maintain the level of obscurity desired. A full search and rescue training evolution may take up to 20 minutes. For this training, the building is kept closed to provide a dark, smoke-filled environment. In case of an emergency, there are exhaust fans that can be activated to remove the smoke through rooftop units rapidly. When this happens, the velocities of air do cause rapid dissipation of the smoke. Nearby buildings will not be affected. As a result of this design, other than a possibility of brief visible impacts, there are no unhealthful effects of exposure to the smoke. The firing range is an indoor range that will be designed with all modem safety features, including building ventilation systems such as a HEPA type of filtering system designed to contain any airbome lead particles from the firing of ammunition. These systems have been in use on indoor firing ranges for many years and have a very good reputation of filtering intemal emissions to the extent that there is no significant exposure to anyone outside the building. w P:\RDG0803 - Carlsbad First Responders Facility\Air Qualily\Air Qualily.doc «07/01/08» 21 LSA ASSOCIATES, INC.

Localized air quality impacts would occur when emissions from vehicular traffic increase in local areas as a result of the proposed project. The primary mobile-source pollutant of local concem is CO, which is a direct function of vehicle idling time and, thus, traffic flow conditions. CO transport is extremely limited; it disperses rapidly with distance from the source under normal meteorological conditions. However, under certain extreme meteorological conditions, CO concentrations proximate to a congested roadway or intersection may reach unhealthful levels, affecting local sensitive receptors (residents, schoolchildren, the elderly, hospital patients, etc.). Typically, high CO concentrations are associated with roadways or intersections operating at unacceptable levels of service or with extremely high traffic volumes. In areas with high ambient background CO concentrations, modeling is recommended to determine a project's effect on local CO levels. An assessment of project-related impacts on localized ambient air quality requires that future ambient air quality levels be projected. Ambient CO levels monitored at the Escondido - East Valley Parkway Station, the air quality monitoring station closest to the project site that records CO levels, are considered representative of the site conditions. They showed a highest recorded one-hour concentration of 5.9 ppm (State standard is 20 ppm) and a highest eight-hour concentration of 3.61 ppm (State standard is 9 ppm) during the past three years (see Table A). The highest CO concentrations would occur during peak traffic hours; hence, CO impacts calculated under peak traffic conditions represent a worst-case analysis. Based on the same Traffic Impact Analysis used for the long-term regional analysis above, CO hot-spot analyses were conducted for existing and future-year conditions. The impact on local CO levels was assessed with the ARB 9- approved CALINE4 air quality model, which allows microscale CO concentrations to be estimated ^ along roadway corridors or near intersections. This model is designed to identify localized concentrations of CO, often termed "hot spots." A brief discussion of input to the CALINE4 model ^ follows. The analysis was peri^ormed for the worst-case wind angle and wind speed condition; it is ^ based upon the following assumptions: ^ • Intersections were selected from those analyzed in the traffic study based on the worst level of service deterioration, the highest project-related vehicle turning movements, and proximity to the * project site. • Twenty receptor locations with the possibility of extended outdoor exposure from 8 to 17 m (approximately 26 to 56 ft) of the roadway centeriine near intersections were modeled to determine CO concentrations. m • The calculations assume a meteorological condition of almost no wind (0.5 m/second), a H suburban topographical condition between the source and receptor, and a mixing height of 1,000 m, representing a worst-case scenario for CO concentrations. W • CO concentrations are calculated for the one-hour averaging period and then compared to the il one-hour standards. CO eight-hour averages are extrapolated and compared to the eight-hour standards; for a worst-case scenario, the nonattainment area persistence factor of 0.7 was used to Ml predict the eight-hour average. Concentrations are given in ppm at each of the receptor locations. P:\RDG0803 - Carlsbad First Responders FacilityVAir QualilyVAir Quality.doc «07/01/08» 22 LSA ASSOCIATES,INC.

CALIFORNIA • The "at-grade" link option with speed adjusted based on average cmise speed and number of vehicles per lane per hour was used rather than the "intersection" link selection in the CALINE4 model (Caltrans has suggested that the "intersection" link should not be used due to an inappropriate algorithm based on outdated vehicle distribution). Emission factors from the EMFAC2007 model were used for the vehicle fleet. • As recommended in Air Quality Technical Analysis Notes (Caltrans 1988), the second-highest annual maximum one-hour average concentration during a three-year period, was used as the background value. The highest levels of the second highest one-hour and eight-hour CO concentrations monitored at the Escondido Station in the past three years were 5.8 ppm for the one-hour CO and 3.3 ppm for the eight-hour CO. These "background" concentrations are then added to the model results for future with and without the proposed project conditions. Table J lists the CO concentrations for the existing without and with the project scenarios at 3 intersections in the project vicinity that would be most affected by project-related traffic. As can be seen in this Table, the project-related increase in CO concentrations at these intersections would be 0.3 ppm or less for the one-hour and 0.2 ppm or less for the eight-hour periods. Since no federal or State standards would be exceeded, these changes in CO concentrations would not be considered significant. Therefore, no mitigation is required.

Table K: Greenhouse Gas Emissions m Ml Ml li Emission Source Emissions (tons per year) Emission Source CO2 CH4 N2O COje Vehicles 370 0.026 0.039 380 Electricity Production 260 0.0028 0.0016 260 Natural Gas Combustion 530 0.01 0.0096 530 Total Annual Emissions 1,200 0.039 0.05 1,200 Note: Numbers in table may not appear to add up correctly due to rounding of all numbers to two significant digits. Due to the global nature of this phenomenon and the scale of the emissions, total emissions are expressed in units of teragrams (a trillion [lO'^J grams or 1 million metric tons [tonnes]) per year (Tg/year), This is the standard metric unit used woridwide. The total annual emissions of 1,200 tons/year of C02e is approximately 0.0011 million metric tonnes of CO2Q. Due to the many uncertainties of the affects of increased GHG concentrations, there are no federal, State, or local emissions thresholds established for GHGs such as CO2. As a comparison, the existing emissions from the entire SANDAG region are estimated to be approximately 40 million metric tonnes of COje per year and approximately 496.95 million metric tonnes of COje per year for the entire State. As described above, project-related GHG emissions are not confined to a particular air basin but are dispersed woridwide. Consequently, it is speculative to determine how project-related GHG emissions would contribute to global climate change and how global climate change may impact Califomia. Therefore, project-related GHG emissions are not project-specific impacts to global warming but are instead the project's contribution to this cumulative impact. As stated previously, project-related CO2 emissions and their contribution to global climate change impacts in the State'of Califomia are less than significant and less than cumulatively considerable because: (I) the project's impacts alone would not cause or significantly contribute to global climate change, and (2) the net increase in air pollutant emissions would not exceed the County thresholds for criteria pollutants. m m P:\RDG0803 - Carlsbad First Responders Facility\AirQuality\AirQuality.doc «07/0l/08» 24 im m J'UNE^^78'^'^^''• OUALITY ANALYSIS " CARLSBAD JOINT FIRST RESPONDERS TRAINING FACILITY ~ ^ — . CITY OF CARLSBAD, CALIFORNIA 5.5 REGIONAL AIR QUALITY STRATEGY CONSISTENCY A regional air quality management plan describes air pollution control strategies to be taken by counties or regions classified as nonattainment areas. The SDAPCD has developed the 2004 RAQS to bring the area into compliance with the requirements of federal and State air quality standards. The RAQS uses the assumptions and projections by local planning agencies to determine control strategies for regional compliance status. Therefore, any projects causing a significant impact on air quality would impede the progress of the RAQS. For a project in the Basin to be consistent with the RAQS, the pollutants emitted from the project must not exceed the local significance threshold or cause a significant impact on air quality. If feasible mitigation measures can be implemented to reduce the project's impact level from significant to less than significant under CEQA, the project is considered to be consistent with the RAQS. A consistency analysis determination plays an essential role in local agency project review by linking local planning and unique individual projects to the RAQS in the following ways: it fulfills the CEQA goal of fully informing local agency decision makers of the environmental costs of the project under consideration at a stage early enough to ensure that air quality concerns are fully addressed, and it provides the local agency with ongoing information, assuring local decision makers that they are making real contributions to clean air goals defined in the most current RAQS (adopted in 2004). Because the RAQS is based on projections from local General Plans, projects consistent with the local General Plan are considered consistent with the RAQS. As shown above, the long-term emissions that will be generated by the proposed project would not exceed the local significance thresholds. Therefore, the proposed project is considered to be U consistent with the SANDAG forecast, and is therefore consistent with the RAQS. ^ 5.6 AIR QUALITY CUMULATIVE IMPACTS iM ^ quality impacts. HP" The project would contribute criteria pollutants to the area during temporary project construction. A number of individual projects in the area may be under construction simultaneously with the proposed project. Depending on construction schedules and actual implementation of projects in the area, generation of fugitive dust and pollutant emissions during construction could result in substantial short-term increases in air pollutants. This would be a contribution to short-term cumulative air Under the cumulative conditions, the Traffic Analysis included vehicular trips from the proposed ^ project and all present and future projects in the project vicinity. Therefore, CO hot spot concentrations calculated at these intersections include the cumulative traffic effect. Based on Table J, no significant cumulative CO impacts would occur. Additionally, the project would not result in significant operational air quality impacts. Thus, it is anticipated that these additional emissions would not contribute significantly to cumulative air quality impacts.
