Chapter 1 Introduction
The purpose of this air quality and greenhouse gas (GHG) technical report is to identify air quality and GHG impacts that may be associated with the Infinite 101 Project (proposed project). The analysis provided in this report evaluates the potential for construction and operation of the proposed project to result in significant impacts on air quality and GHG emissions. The report includes a description of the environmental setting for the proposed project, including existing conditions and applicable laws and regulations. It also documents the assumptions, methodologies, and findings used to evaluate air quality and GHG impacts. The project is subject to environmental review pursuant to the California Environmental Quality Act (CEQA). It is anticipated that the City of South San Francisco (City), the lead agency for the project, will use this technical report to inform the proposed project’s CEQA analysis.
1.1 Project Description The Infinite 101 project site is in the city of South San Francisco. U.S. 101 is east of the site, Terminal Court is to the north, a navigable slough to the south, and existing commercial and industrial development to the west (ESA 2019).1 A parking lot and other structures would be demolished and replaced with new research-and-development (R&D) and amenity uses. Overall, the proposed project would construct approximately 696,343 square feet (sf) of new uses in two six-story buildings (I101N and I101S). In addition, an approximately 339,354 sf, seven-story parking garage would be incorporated on the project site south of the I101S building. The I101N building would have an area of approximately 345,142 sf and be six stories high (i.e., approximately 114 feet). The building would include approximately 328,771 sf of R&D uses that would be spread out across all levels of the building. The ground floor of the I101N building would include a lobby, approximately 9,055 sf of conference space, and approximately 7,316 sf of restaurant space. Outdoor terraces would be incorporated on multiple levels of the proposed building for use by building tenants. The I101S building would be south of and immediately adjacent to the I101N building and have an area of approximately 351,201 sf. It would also be six stories high, or approximately 114 feet. The building would include approximately 340,243 sf of R&D uses across all building levels, in addition to the lobby, and a 10,958 sf public gym on the ground floor of the building. The I101S building would also incorporate outdoor terraces for use by building tenants on multiple levels. There would also be three emergency generators with Tier 2 engines on the project site. The generators would be located on the ground floor in separate generator rooms within the I101N and I101S buildings. All buildings on the project site would be tied together through landscaping and open space, creating pedestrian- and bike-friendly connections throughout the highly amenitized campus. A shared internal road would provide vehicular access to the garage, surface parking, and loading areas. It would also provide access for fire vehicles. A center landscaped courtyard would be located
1 The navigable slough is a remnant tidal channel that cuts through a commercial district in the city of South San Francisco and connected to San Francisco Bay.

along the interior of the project site and framed by the shape of the buildings to prioritize the pedestrian experience and outdoor amenities. Two vehicle entrances to the site would be provided from Terminal Court to the north and Shaw Road to the south. Figure 1 shows the site plan for the proposed project.

Chapter 2 Air Quality
2.1 Regulatory Setting This section provides a summary of the regulatory setting at the federal, state, regional, and local levels that are applicable to the proposed project. The federal Clean Air Act (CAA) and its subsequent amendments form the basis for the nation’s air pollution control effort. The U.S. Environmental Protection Agency (EPA) is responsible for implementing most aspects of the CAA. Key to the CAA are the National Ambient Air Quality Standards (NAAQS) for criteria pollutants. The CAA delegates enforcement of the NAAQS to the states. In California, the California Air Resources Board (CARB) is responsible for enforcing air pollution regulations and ensuring that the NAAQS and the California Ambient Air Quality Standards (CAAQS) are met. CARB, in turn, delegates regulatory authority for stationary sources and other air quality management responsibilities to local air agencies. The Bay Area Air Quality Management District (BAAQMD) is the local air agency for the project site. The following sections provide more detailed information on the federal, state, and local air quality regulations that apply to the proposed project.
2.1.1 Federal
Criteria Air Pollutants
National Ambient Air Quality Standards EPA has been charged with implementing national air quality programs. Its air quality mandates draw primarily from the federal CAA, which was enacted in 1963. The most recent major amendments were made by Congress in 1990. The CAA required EPA to establish the NAAQS for six common air pollutants, which are found all over the United States. These pollutants are referred to as criteria air pollutants. EPA has established primary and secondary NAAQS for the following criteria air pollutants: ozone, carbon monoxide (CO), nitrogen dioxide (NO2), sulfur dioxide (SO2), respirable particulate matter with an aerodynamic diameter of 10 micrometers or less (PM10), fine particulate matter with an aerodynamic diameter of 2.5 micrometers or less (PM2.5), and lead. The NAAQS are shown in Table 1. The primary standards protect public health; the secondary standards protect public welfare. The CAA also required each state to prepare a State Implementation Plan (SIP) for attaining and maintaining the NAAQS. The federal CAA Amendments of 1990 added requirements for states with nonattainment areas to revise their SIPs to incorporate additional control measures for reducing air pollution. California’s SIP is modified periodically to reflect the latest emissions inventories, planning documents, and rules and regulations of the air basins, as reported by their jurisdictional agencies. EPA is responsible for reviewing all SIPs to determine whether they conform to the mandates of the CAA and its amendments and whether implementation would achieve air quality goals. If EPA determines a SIP to be inadequate, EPA may prepare a federal implementation plan that imposes additional control measures. If an approvable SIP is not submitted or implemented within the mandated time frame, sanctions may be applied to transportation funding and stationary air pollution sources in the air basin.

Corporate Average Fuel Economy Standards for Light-Duty Passenger Vehicles The National Highway Traffic Safety Administration (NHTSA) Corporate Average Fuel Economy (CAFE) standards require substantial improvements in fuel economy and reductions in emissions of criteria air pollutants and precursors, as well as GHGs, from all light-duty vehicles sold in the United States. On August 2, 2018, NHTSA and EPA proposed an amendment to the fuel efficiency standards for passenger cars and light trucks and established new standards for model years 2021 through 2026 that would maintain the then-current 2020 standards through 2026—this was known as the
Safer Affordable Fuel-Efficient (SAFE) Vehicles Rule. On September 19, 2019, NHTSA and EPA issued a final action on the One National Program Rule, which is considered Part One of the SAFE Vehicles Rule and a precursor to the proposed fuel efficiency standards. The One National Program Rule
Chapter 2: Air Quality
Air Quality and Greenhouse Gas Technical Report Infinite 101 Project 2-3 June 2023 ICF 104667
enabled NHTSA and EPA to provide nationwide uniform fuel economy and air pollutant standards by 1) clarifying that federal law preempts state and local tailpipe standards, 2) affirming NHTSA’s statutory authority to set nationally applicable fuel economy standards, and 3) withdrawing California’s CAA preemption waiver to set state-specific standards. NHTSA and EPA published their decision to withdraw California’s waiver and finalize the regulatory text related to the preemption on September 27, 2019 (84 Federal Register 51310). California, 22 other states, the District of Columbia, and two cities filed suit against Part One of the SAFE Vehicles Rule on September 20, 2019 (California et al. v. United States Department of Transportation et al., 1:19-cv-02826, U.S. District Court for the District of Columbia). On October 28, 2019, the Union of Concerned Scientists, Environmental Defense Fund, and other groups filed a protective petition for review after the federal government sought to transfer the suit to the District of Columbia (Union of
Concerned Scientists v. National Highway Traffic Safety Administration). The lawsuit filed by California and others has been stayed, pending resolution of the petition. NHTSA and EPA published final rules on April 30, 2020, to amend and establish national air pollutant and fuel economy standards (Part Two of the SAFE Vehicles Rule) (85 Federal Register 24174). The revised rule changes the national fuel economy standards for light-duty vehicles from 46.7 miles per gallon (mpg) to 40.4 mpg in future years. California, 22 other states, and the District of Columbia filed a petition for review of the final rule on May 27, 2020 (California et al. v. United States Department of
Transportation et al., 1:19-cv-02826, U.S. District Court for the District of Columbia). On January 20, 2021, President Biden issued an Executive Order (EO) directing NHTSA and EPA to review the SAFE Vehicles Rule, Part One, and propose a new rule for suspending, revising, or rescinding the rule by April 2021. The EO also requires NHTSA and EPA to propose a new rule for suspending, revising, or rescinding Part Two by July 2021. On April 22, 2021, NHTSA announced that it proposes to repeal the SAFE Vehicles Rule, Part One, allowing California the right to set its own standards (U.S. Department of Transportation, NHTSA 2021). On December 12, 2021, NHTSA repealed the SAFE Vehicles Rule, Part One. On December 19, 2021, NHTSA finalized its vehicle efficiency standards rule to reach a projected industry-wide target of 40 mpg by 2026, an approximately 25 percent increase over the prior SAFE Vehicles Rule. Lastly, on March 9, 2022, EPA reinstated California’s authority under the CAA to implement its own GHG emissions standards and sales mandate regarding zero-emission vehicles. This action concluded EPA’s reconsideration of 2019’s SAFE Vehicles Rule, Part One, by finding that actions under the previous administration, as part of SAFE-1, were decided in error; the actions are now rescinded (EPA 2022a).
Emission Standards for On-Road Heavy-Duty Vehicles EPA has established a series of increasingly strict emission standards for new heavy-duty bus and truck engines. Emissions from heavy-duty trucks are managed by regulations and emission limits implemented at the federal, state, and local levels. In December 2000, EPA signed the Heavy-Duty Highway Rule, which reduces emissions from on-road, heavy-duty diesel trucks by establishing a series of increasingly strict emission standards for new engines. Manufacturers were required to produce new diesel vehicles that meet emissions standards for particulate matter and nitrogen oxide (NOX) beginning with model year 2007, with the phase-in period being between 2007 and 2010. The phase-in period was based on the percentage of sales: (i.e., 50 percent from 2007 to 2009 and 100 percent in 2010). Requirements apply to engines installed in all vehicles with a gross vehicle weight rating (GVWR) above 14,000 pounds as well as some engines installed in vehicles with a GVWR between 8,500 and 14,000 pounds.

Air Quality and Greenhouse Gas Technical Report Infinite 101 Project 2-4 June 2023 ICF 104667
Emission Standards for Non-Road Diesel Engines To reduce emissions from non-road diesel equipment, EPA established a series of increasingly strict emission standards for new non-road diesel engines, also referred to as off-road diesel engines. Tier 1 standards were phased in on newly manufactured equipment from model years 1996 through 2000, depending on the engine horsepower category. Tier 2 standards were phased in on newly manufactured equipment from model years 2001 through 2006. Tier 3 standards were phased in on newly manufactured equipment from model years 2006 through 2008. Tier 4 standards, which require advanced emission-control technology, were phased in from model years 2008 through 2015.
Hazardous Air Pollutants and Toxic Air Contaminants Toxic air contaminants (TACs) or, in federal parlance, hazardous air pollutants (HAPs), are a defined set of airborne pollutants that may pose a present or potential hazard to human health. A TAC is defined as an air pollutant that may cause or contribute to an increase in mortality or serious illness or pose a hazard to human health. TACs are usually present in minute quantities in the ambient air; however, their high toxicity or health risk may pose a threat to public health even at low concentrations. A wide range of sources, from industrial plants to motor vehicles, emit TACs. The health effects associated with TACs are quite diverse and generally assessed locally rather than regionally. TACs can cause long-term health effects, such as cancer, birth defects, neurological damage, asthma, bronchitis, or genetic damage, or short-term acute affects, such as watery eyes, respiratory irritation (a cough), a running nose, throat pain, or headaches. For evaluation purposes, TACs are separated into carcinogens and noncarcinogens, based on the nature of the physiological effects associated with exposure to the pollutant. Carcinogens are assumed to have no safe threshold below which health impacts would not occur. This contrasts with criteria air pollutants for which acceptable levels of exposure can be determined and for which ambient standards have been established (Table 1). The cancer risk from TACs is expressed as the excess cancer cases per million exposed individuals, typically over a lifetime of exposure. EPA and CARB regulate HAPs and TACs, respectively, through statutes and regulations that generally require the use of the maximum available control technology or best available control technology for air toxics to limit emissions.
2.1.2 State
Criteria Air Pollutants CARB is the agency responsible for coordinating and overseeing state and local air pollution control programs in California as well as implementing the California Clean Air Act (CCAA). The CCAA required CARB to establish the CAAQS for the same criteria air pollutants for which EPA established the NAAQS, along with sulfates, hydrogen sulfide, vinyl chloride, and visibility-reducing particulate matter. The CAAQS are summarized in Table 1. In most cases, the CAAQS are more stringent than the NAAQS. Differences in the NAAQS and CAAQS are generally explained by the health-effects studies considered during the standard-setting process as well as interpretation of the studies. In addition, the CAAQS incorporate a margin of safety to protect sensitive individuals.
Chapter 2: Air Quality
Air Quality and Greenhouse Gas Technical Report Infinite 101 Project 2-5 June 2023 ICF 104667
In California, EPA has delegated authority to prepare SIPs to CARB, which, in turn, has delegated that authority to individual air districts. Traditionally, CARB has established state air quality standards, maintaining oversight authority in air quality planning, developing programs for reducing emissions from motor vehicles, developing air emission inventories, collecting air quality and meteorological data, and approving SIPs. The CCAA requires all local air districts in the state to endeavor to attain and maintain the CAAQS by the earliest date practical. The CCAA specifies that local air districts should focus particular attention on reducing emissions from transportation and area-wide emission sources. The CCAA substantially adds to the authority and responsibilities of air districts. The CCAA designates air districts as lead air quality planning agencies, requires air districts to prepare air quality plans, and grants air districts the authority to implement transportation control measures. The CCAA also emphasizes control of “indirect and area-wide sources” of air pollutant emissions. The CCAA gives local air pollution control districts explicit authority to regulate indirect sources of air pollution and establish traffic control measures.
Low-Emission Vehicle Program Regulation CARB has developed various regulations to establish exhaust emissions standards for both on-road and off-road vehicles, as mentioned in the above discussion of CAFE standards for light-duty passenger vehicles.
Truck and Bus Regulation CARB focused its efforts to reduce emissions of NOX and other criteria pollutants, as well as diesel particulate matter (DPM) from diesel vehicles, by adopting the Truck and Bus Regulation in 2008. This regulation applies to any diesel-fueled, dual-fuel, or alternative diesel-fueled vehicle on public highways. It also applies to yard trucks with on-road engines, yard trucks with off-road engines used for agricultural operations, school buses, and vehicles with a GVWR of more than 14,000 pounds. The purpose of the regulation is to require nearly all trucks and buses registered in the state to have a 2010 or newer engine by 2023. Compliance schedules have been established for lighter vehicles (GVWR of 14,000–26,000 pounds) and heavier vehicles (GVWR of 26,001 or more pounds) (CARB 2021b). Since January 1, 2020, only vehicles that meet the requirements of the Truck and Bus Regulation are allowed to register with the California Department of Motor Vehicles.
Carl Moyer Program The Carl Moyer Memorial Air Quality Standards Attainment Program (Carl Moyer Program) is a voluntary program that offers grants to owners of heavy-duty vehicles and equipment. The program is a partnership between CARB and the local air districts throughout the state to reduce air pollution emissions from heavy-duty engines. Locally, the air districts administer the Carl Moyer Program.
Toxic Air Contaminants California regulates TACs primarily through the Tanner Act (Assembly Bill [AB] 1807) and the Hot Spots Act (AB 2588). The Tanner Act (AB 1807) created California’s program to reduce exposure to air toxics. CARB defines TACs as air pollutants that may cause or contribute to an increase in mortality or an increase in serious illness or pose a present or potential hazard to human health. CARB has formally identified more than 200 substances and groups of substances as TACs (CARB 2022a). Direct exposure to these pollutants has been shown to cause cancer, birth defects, damage to the brain and nervous system, and respiratory disorders. The Hot Spots Act (AB 2588)
Chapter 2: Air Quality
Air Quality and Greenhouse Gas Technical Report Infinite 101 Project 2-6 June 2023 ICF 104667
supplements the AB 1807 program by requiring a statewide air-toxics inventory, notification of people exposed to a significant health risk, and facility plans to reduce these risks. The California Office of Environmental Health Hazard Assessment (OEHHA) is required to develop guidelines for health risk assessments (HRAs) under the Air Toxics Hot Spots Program. These guidelines provide the scientific basis for the values used to assess the risk of emissions exposure from facilities and new sources (OEHHA 2015). In August 1998, CARB identified particulate emissions from diesel-fueled engines as TACs. In September 2000, CARB approved a comprehensive diesel risk-reduction plan to reduce emissions from both new and existing diesel-fueled engines and vehicles. As an ongoing process, CARB reviews air contaminants and identifies those that have been classified as TACs. CARB also continues to establish new programs and regulations for the control of TACs, including DPM, as appropriate. CARB has adopted diesel exhaust control measures as well as more stringent emissions standards for various transportation-related mobile sources of emissions, including transit buses and off-road diesel equipment (e.g., tractors, generators). Over time, the replacement of older vehicles results in a vehicle fleet that produces substantially lower levels of TACs. Mobile-source emissions of TACs (e.g., benzene, 1,3-butadiene, DPM) have been reduced significantly over the last decade and will be reduced further in California through a progression of regulatory measures (e.g., low-emission vehicle/clean-fuel and Phase II reformulated-gasoline regulations) and control technologies. It is expected that DPM concentrations will continue to decline. Adopted regulations are also expected to continue to reduce formaldehyde emissions emitted by cars and light-duty trucks. As emissions are reduced, it is expected that risks associated with exposure to the emissions will also be reduced. CARB developed multiple air toxic control measures to address specific mobile- and stationary-source categories that can have an impact on the public health of communities. The measures focused on reducing public exposure to DPM and TACs from mobile sources, such as commercial trucks, buses, solid-waste collection vehicles, and cargo-handling equipment at ports. The Airborne Toxic Control Measure to Limit Diesel-Fueled Commercial Motor Vehicle Idling (California Code of Regulations [CCR] Title 13, Section 2485) required heavy-duty trucks with a GVWR of more than 10,000 pounds to not idle the primary engine for more than 5 minutes at any given time or operate an auxiliary power system for more than 5 minutes within 100 feet of a restricted area.
2.1.3 Local
Bay Area Air Quality Management District At the local level, responsibilities of air quality districts include overseeing stationary-source emissions, approving permits, maintaining emissions inventories, maintaining air quality stations, overseeing agricultural burning permits, and reviewing air quality–related sections of environmental documents required by CEQA. The air quality districts are also responsible for establishing and enforcing local air quality rules and regulations that address the requirements of federal and state air quality laws and ensuring that the NAAQS and CAAQS are met. The proposed project falls under the jurisdiction of BAAQMD, which has local air quality jurisdiction over projects in the San Francisco Bay Area Air Basin (SFBAAB), including San Mateo County. BAAQMD developed advisory emissions thresholds to assist CEQA lead agencies in determining the level of significance of a project’s emissions, as outlined in its 2017 CEQA Guidelines (BAAQMD 2017a). In April 2023, BAAQMD released updated CEQA Guidelines; the emissions thresholds
Chapter 2: Air Quality
Air Quality and Greenhouse Gas Technical Report Infinite 101 Project 2-7 June 2023 ICF 104667
specified in the updated guidelines are the same as the 2017 guidelines (BAAQMD 2023). BAAQMD has also adopted air quality plans to improve air quality, protect public health, and protect the climate. This includes the 2017 Clean Air Plan: Spare the Air, Cool the Climate (BAAQMD 2017b). The 2017 Clean Air Plan was adopted by BAAQMD on April 19, 2017. The 2017 Clean Air Plan updates the prior 2010 Bay Area ozone plan and outlines feasible measures to reduce ozone. It provides a control strategy to reduce particulate matter, air toxics, and GHGs in a single, integrated plan and establishes the emissions control measures to be adopted or implemented. The 2017 Clean Air Plan contains the primary goals outlined below; consistency with these goals is evaluated in this section.
•Protect Air Quality and Health at the Regional and Local Scale. Attain all state and national airquality standards, and eliminate disparities among Bay Area communities regarding the cancerhealth risk from TACs.
•Protect the Climate. Reduce Bay Area GHG emissions to 40 percent below 1990 levels by 2030and 80 percent below 1990 levels by 2050. The 2017 Clean Air Plan is the most currentapplicable air quality plan for the air basin. Consistency with this plan is the basis fordetermining whether a project would conflict with or obstruct implementation of an air qualityplan.In addition to air quality plans, BAAQMD also adopts rules and regulations to improve existing and future air quality. The proposed project may be subject to the district rules outlined below.
•Regulation 2, Rule 2 (New Source Review)—This regulation contains requirements for bestavailable control technology and emission offsets.
•Regulation 2, Rule 5 (New Source Review of Toxic Air Contaminates)—This regulation outlinesguidance for evaluating TAC emissions and their potential health risks.
•Regulation 6, Rule 1 (Particulate Matter)—This regulation restricts emissions of particulatematter darker than a 1 on the Ringlemann Chart to less than 3 minutes in any 1 hour.
•Regulation 7 (Odorous Substances). This regulation establishes general odor limitations onodorous substances and specific emission limitations on certain odorous compounds.
•Regulation 8, Rule 3 (Architectural Coatings). This regulation limits the quantity of reactiveorganic gas (ROG) in architectural coatings.
•Regulation 9, Rule 6 (NOX Emission from Natural Gas–Fired Boilers and Water Heaters). Thisregulation limits emissions of NOX generated by natural gas–fired boilers.
•Regulation 9, Rule 8 (Stationary Internal-Combustion Engines). This regulation limits emissionsof NOX and CO from stationary internal-combustion engines of more than 50 horsepower.
•Regulation 11, Rule 2 (Hazardous Pollutants – Asbestos Demolition, Renovation, andManufacturing). This regulation, which incorporates EPA’s National Emissions Standards forHazardous Air Pollutants, controls emissions of asbestos to the atmosphere during demolition,renovation, and manufacturing.

2.2 Existing Setting
2.2.1 Topography and Meteorology Although the primary factors that determine air quality are the locations of air pollutant sources and the amount of pollutants emitted from those sources, meteorological conditions and topography are also important factors. Atmospheric conditions, such as wind speed, wind direction, and air temperature gradients, interact with the physical features of the landscape to determine the movement and dispersal of air pollutants. Unique geographic features throughout the state define 15 air basins with distinctive regional climates. The air quality study area for the proposed project is on San Francisco Peninsula in the SFBAAB. The peninsula region of the San Francisco Bay Area extends from the area northwest of San José to the Golden Gate. The Santa Cruz Mountains, part of the Pacific Coast Ranges, extend through the center of the peninsula, with elevations exceeding 2,000 feet at the south end but gradually decreasing to 500 feet in South San Francisco where the mountain range terminates. On the west side of the mountains lie small coastal towns, such as Half Moon Bay and Pacifica, that, because of coastal ocean upwelling and northwest winds, experience a high incidence of cool, foggy weather in the summer. On the east side of the mountain range lie the larger cities. Cities in the southeastern peninsula experience warmer temperatures and few foggy days because the marine layer, with an average depth of 1,700 feet, is blocked by the 2,000-foot ridge to the west. At the north end of the peninsula lies San Francisco. Because most of the topography of San Francisco is below 200 feet, the marine layer is able to flow across most of the city, making its climate cool and windy.
Chapter 2: Air Quality
Air Quality and Greenhouse Gas Technical Report Infinite 101 Project 2-9 June 2023 ICF 104667
The Santa Cruz Mountains exhibit a partial blocking effect in South San Francisco, which keeps summertime maximum temperatures slightly higher than locations on the coast. For example, in Half Moon Bay and San Francisco, average maximum daily summertime temperatures are in the mid-60s, while maximum temperatures for South San Francisco range from 65 degrees Fahrenheit (°F) to 75°F (National Oceanic and Atmospheric Administration [NOAA] 2023). Conversely, large temperature gradients are not seen in the minimum temperatures. Average minimum temperatures at Half Moon Bay are about 43°F in winter and 50°F to 52°F in summer. The east peninsula, near South San Francisco, reports winter minimum temperatures of 40°F and summer minimum temperatures of 52°F to 55°F (NOAA 2023). Annual average wind speeds range from 5 to 10 miles per hour (mph) throughout the peninsula. The tendency is for the higher wind speeds to be found along the western coast. However, winds on the east side of the peninsula can also be high in certain areas because low-lying areas in the mountain range, at San Bruno Gap and Crystal Springs Gap, commonly allow the marine layer to pass across the peninsula. The prevailing winds are westerly along the peninsula's west coast. Individual sites can show significant differences, however. For example, Fort Funston in western San Francisco County shows a southwest wind pattern, while Pillar Point in San Mateo County to the south shows a northwest wind pattern. Sites on the east side of the mountains also show a westerly pattern, although their wind patterns show an influence from local topographic features. That is, a rise in elevation of a few hundred feet will induce a flow around that feature instead of over it during stable atmospheric conditions. This can change the wind pattern by as much as 90 degrees over short distances. On mornings without a strong pressure gradient, areas on the east side of the peninsula often experience an eastern flow in the surface layer, which is induced by an upslope flow on east-facing slopes and by the bay breeze. The bay breeze is rarely seen after noon because the stronger sea breeze dominates the flow pattern. On the peninsula, there are two important gaps in the Santa Cruz Mountains. The larger of the two is the San Bruno Gap, extending from Fort Funston on the ocean side to the San Francisco International Airport on the bay side. Because the gap is oriented in the same northwest-to-southeast direction as the prevailing winds, and because the elevations along the gap are under 200 feet, marine air is easily able to penetrate into the bay. The other gap in the Santa Cruz Mountains is the Crystal Springs Gap, along Highway 92 between Half Moon Bay and San Carlos. The low point is 900 feet, with elevations of 1,500 feet north and south of the gap. As the sea breeze strengthens on summer afternoons, the gap permits maritime air to pass across the mountains. Its cooling effect is commonly seen from San Mateo to Redwood City. Rainfall amounts on the east side of the peninsula are somewhat lower than on the west side, with San Francisco and Redwood City reporting an average of 19.5 inches per year. On the west side, Half Moon Bay reports 25 inches per year. Areas in the Santa Cruz Mountains have significantly higher rainfall totals, especially west of the ridge line, because of induced condensation from orographic lifting, proximity to a moisture source, and fog drip. Air pollution potential is highest along the southeast portion of the peninsula because this area is protected from the high winds and fog of the marine layer, the emissions density is relatively high, and pollutant transport from upwind sites is possible. In San Francisco, to the north, pollutant emissions are high, but winds are generally fast enough to carry the pollutants away before they can accumulate.

2.2.2 Criteria Air Pollutants The following provides a summary discussion of the primary and secondary criteria air pollutants of key concern. In general, primary pollutants are directly emitted into the atmosphere, and secondary
pollutants are formed by chemical reactions in the atmosphere.
Ozone Ozone, the main ingredient in urban smog, is not emitted directly into the air but, rather, created by chemical reactions between hydrocarbons and NOX, both byproducts of the internal-combustion engine, in the presence of sunlight. The CARB definition for ROG includes all hydrocarbons except those exempted by CARB that contribute to smog formation, whereas the EPA definition for volatile organic compounds (VOCs) includes all hydrocarbons except those exempted by EPA. Generally speaking, ROGs and VOCs are similar but not identical; although the terms are used interchangeably, ROG is used for purposes of this analysis. There are no separate NAAQS or CAAQS for ROG. Carcinogenic forms of ROGs are TACs (e.g., benzene). ROG consists of compounds made up primarily of hydrogen and carbon atoms. Internal combustion associated with motor vehicles is the major source of hydrocarbons. Other sources of ROGs are emissions associated with the use of paints and solvents, the application of asphalt paving, and the use of household consumer products, such as aerosols. The two major forms of NOX are nitric oxide (NO) and NO2. NO is a colorless, odorless gas that forms from atmospheric nitrogen and oxygen when combustion takes place under high temperatures and/or high pressure. NO2 is a reddish-brown, irritating gas formed by the combination of NO and oxygen. In addition to serving as an integral participant in ozone formation, NOX also acts as an acute respiratory irritant and increases susceptibility to respiratory pathogens. Ozone poses a higher risk to those who already suffer from respiratory diseases (e.g., asthma), children, older adults, and people who are active outdoors. Exposure to ozone at certain concentrations can make breathing more difficult, cause shortness of breath and coughing, inflame and damage the airways, aggregate lung diseases, increase the frequency of asthma attacks, and cause chronic obstructive pulmonary disease. Studies show associations between short-term ozone exposure and nonaccidental mortality, including deaths from respiratory issues. Studies also suggest that long-term exposure to ozone may increase the risk of respiratory-related deaths (EPA 2022b). The concentration of ozone at which health effects are observed depends on an individual’s sensitivity, level of exertion (i.e., breathing rate), and duration of exposure. Studies show large individual differences in the intensity of symptomatic responses, with one study finding no symptoms to the least-responsive individual after a 2-hour exposure to 400 parts per billion of ozone and a 50 percent decrement in forced airway volume in the most responsive individual. Although the results vary, evidence suggests that sensitive populations (e.g., asthmatics) may be affected on days when the 8-hour maximum ozone concentration reaches 80 parts per billion (EPA 2022c).In addition to human health effects, ozone has been tied to crop damage, typically in the form of stunted growth, leaf discoloration, cell damage, and premature death. Ozone can also act as corrosives and oxidants, resulting in property damage, such as the degradation of rubber products and other materials.

Air Quality and Greenhouse Gas Technical Report Infinite 101 Project 2-11 June 2023 ICF 104667
Carbon Monoxide CO is a colorless, odorless, and toxic gas produced by incomplete combustion of carbon substances, such as gasoline or diesel fuel. CO is considered a local pollutant because it tends to accumulate in the air locally. The primary adverse health effect associated with CO is interference with normal oxygen transfer to the blood, which may result in tissue oxygen deprivation. Exposure to CO at high concentrations can also cause fatigue, headaches, confusion, dizziness, and chest pain. There are no ecological or environmental effects for ambient CO (CARB 2019).
Particulate Matter Particulate matter (PM) consists of finely divided solids or liquids, such as soot, dust, aerosols, fumes, and mists. Two forms of fine particulates are now recognized: respirable coarse particles with an aerodynamic diameter of 10 micrometers or less, or PM10, and respirable fine particles with an aerodynamic diameter of 2.5 micrometers or less, or PM2.5. Particulate discharge into the atmosphere results primarily from industrial, agricultural, construction, and transportation activities. However, wind on arid landscapes also contributes substantially to local particulate loading. PM is considered both a local and a regional pollutant. Particulate pollution can be transported over long distances and may adversely affect humans, especially people who are naturally sensitive or susceptible to breathing problems (i.e., asthmatics). Numerous studies have linked PM exposure to premature death in people with preexisting heart or lung disease. Other symptoms of exposure may include nonfatal heart attacks, irregular heartbeats, aggravated asthma, decreased lung function, and increased respiratory symptoms. Depending on composition, PM10 and PM2.5 can also affect water quality and acidity, deplete soil nutrients, damage sensitive forests and crops, affect ecosystem diversity, and contribute to acid rain (EPA 2022a).
Sulfur Dioxide SO2 is an colorless, irritating gas with a rotten egg smell. It forms primarily from the combustion of fossil fuels containing sulfur. SO2 is considered a local pollutant because it tends to accumulate in the air locally. High concentrations of SO2 can result in temporary breathing impairment for asthmatic children and adults who are active outdoors. Short-term exposure of asthmatic individuals to elevated SO2 levels during moderate activity may result in breathing difficulties that can be accompanied by symptoms such as wheezing, chest tightness, or shortness of breath. Other effects that have been associated with longer-term exposures to high concentrations of SO2, in conjunction with high levels of PM, include aggravation of existing cardiovascular disease, respiratory illness, and alterations in lung defenses. SO2 also is a major precursor to PM2.5, which is a significant health concern and a main contributor to poor visibility (see also the discussion of health effects of PM, above).
Lead Lead is a naturally occurring metal that can be a constituent of air, water, and the biosphere. It is considered a local pollutant because it tends to accumulative in the air locally. This highly toxic metal, which was used for many years in everyday products, has been found to cause a range of health effects, from behavioral problems and learning disabilities to seizures and death. Effects on children’s nervous systems are one of the primary health risk concerns from lead. When lead is present in high concentrations, children can even suffer irreversible brain damage and death. Children 6 years old and under are most at risk because their bodies are growing quickly.

Since the 1980s, lead has been phased out in gasoline, reduced in drinking water, reduced in industrial air pollution, and banned or limited in consumer products. Gasoline-powered automobile engines were a major source of airborne lead through the use of leaded fuels; however, the use of leaded fuel has been mostly phased out. Since this has occurred, the ambient lead levels have dropped dramatically.
Other Criteria Pollutants CARB has also established CAAQS for hydrogen sulfide (H2S), sulfates, vinyl chloride, and visibility-reducing particles. These pollutants are not addressed by federal standards. Below is a summary of these pollutants and a description of their physical properties, health and other effects, sources, and the extent of the problems.
Hydrogen sulfide emissions often are associated with geothermal activity, oil and gas production, refining, sewage treatment plants, and confined animal-feeding operations. H2S in the atmosphere would most likely oxidize into SO2, which can lead to acid rain. At low concentrations, H2S may cause dizziness, headaches, and irritation to the eyes, mucous membranes, and respiratory system. In high concentrations, H2S is extremely hazardous (i.e., 800 parts per million can cause death), especially in enclosed spaces. The Occupational Safety and Health Administration (OSHA) has the primary responsibility for regulating workplace exposure to H2S.
Sulfates are another particulate product that result from the combustion of sulfur-containing fossil fuels; however, the majority of ambient sulfates are formed in the atmosphere. When SO2 comes in contact with oxygen, it precipitates out into sulfates. Data collected in the Mojave Desert Air Basin have demonstrated that levels of sulfates are significantly lower than the health standards. The health effects associated with SO2 and sulfates, more commonly known as sulfur oxides (SOX), include respiratory illnesses, decreased pulmonary-disease resistance, and aggravation of cardiovascular diseases. When acidic pollutants and particulates are also present, SO2 tends to have an even more toxic effect. Increased PM derived from SO2 emissions also contributes to impaired visibility. In addition to particulates, sulfur trioxide and sulfate ion are precursors to acid rain; SOX and NOX are the leading precursors to acid rain, which can lead to corrosion of human-made structures and cause acidification of water bodies.
Visibility-reducing particles consist of PM generated from a variety of natural and human-made sources. They vary greatly in shape, size, and chemical composition. Some haze-causing particles (e.g., windblown dust and soot) are directly emitted into the air, whereas others are formed in the air from the chemical transformation of gaseous pollutants (e.g., sulfates, nitrates, organic carbon particles), which are the major constituents of fine PM. These fine particles, caused largely by the combustion of fuel, can travel hundreds of miles and cause visibility impairment. California has been labeled unclassified for visibility—CARB has not established a method for measuring visibility with the precision and accuracy needed to designate areas as attainment or nonattainment areas.
Vinyl chloride is a colorless, sweet-smelling gas at ambient temperature. Landfills, publicly owned treatment works, and polyvinyl chloride production are the major identified sources of vinyl chloride emissions in California. Polyvinyl chloride can be fabricated into several products, such as pipes, pipe fittings, and plastic materials. In humans, epidemiological studies of occupationally exposed workers have linked vinyl chloride exposure to development of liver angiosarcoma, a rare cancer, and have suggested a relationship between exposure and lung and brain cancers.

2.2.3 Local Criteria Pollutant Monitoring Data A number of ambient air quality monitoring stations are located in the SFBAAB to monitor progress toward air quality standards attainment of the NAAQS and CAAQS. There are no monitoring stations in South San Francisco, but there is one monitoring station in San Francisco at 10 Arkansas Street, which is approximately 8 miles from the project site. Recent air quality monitoring results from the nearest monitoring station (Arkansas Street in San Francisco) are summarized in Table 2. The data represent air quality conditions for the last 3 years from which a complete dataset is available (2019–2021). As indicated in Table 2, the Arkansas Street monitoring station has experienced infrequent violations of state and federal air quality standards during the 2019–2021 time period.

2.2.4 Attainment Designations Local monitoring data, included in Table 2, are used to designate areas as nonattainment, maintenance, attainment, or unclassified areas for the NAAQS and CAAQS. The four designations are further defined as follows:
•Nonattainment. Assigned to areas where monitored pollutant concentrations violate thestandard in question.
•Maintenance. Assigned to areas where monitored pollutant concentrations exceeded thestandard in question in the past but are no longer in violation of that standard.
•Attainment. Assigned to areas where pollutant concentrations meet the standard in questionover a designated period of time.
•Unclassified. Assigned to areas where data are insufficient to determine whether a pollutant isviolating the standard in question.Table 3 summarizes the attainment status for San Mateo County with regard to the NAAQS and CAAQS. For ozone and PM2.5, the county is in nonattainment for the federal standards; for PM10, the county is in nonattainment for the state standard only.

2.2.5 Toxic Air Contaminants Although ambient air quality standards have been established for criteria pollutants, no ambient standards exist for TACs. Many pollutants are identified as TACs because of their potential to increase the risk of developing cancer or because of their acute or chronic health risks. For TACs that are known or suspected carcinogens, CARB has consistently found that there are no levels or thresholds below which exposure is risk free. Individual TACs vary greatly in the risks they present. At a given level of exposure, one TAC may pose a hazard that is many times greater than another. TACs are identified and their toxicity is studied by the OEHHA.
Diesel Particulate Matter DPM is generated by diesel-fueled equipment and vehicles. Within the Bay Area, BAAQMD has found that of all controlled TACs, emissions of DPM are responsible for about 82 percent of the total ambient cancer risk (BAAQMD 2017a). Short-term exposure to DPM can cause acute irritation (e.g., eye, throat, bronchial), neurophysiological symptoms (e.g., lightheadedness, nausea), and respiratory symptoms (e.g., cough, phlegm). EPA has determined that diesel exhaust is “likely to be carcinogenic to humans by inhalation” (EPA 2003).
Type II Laboratory Toxic Air Contaminants According to the Health Risk Assessment conducted for the University of California, Davis 2017 Long-
Range Development Plan by Yorke Engineering (Yorke Engineering 2018), a Type II general biological sciences laboratory is known to emit a variety of TAC emissions. Such emissions would occur with the use of the different solvents, preservatives, acids, and other chemicals that are typically found in a laboratory setting.

Naturally Occurring Asbestos Asbestos is the name given to several naturally occurring fibrous silicate minerals. Before the adverse health effects of asbestos were identified, asbestos was widely used as insulation and fireproofing in buildings, and it can still be found in some older buildings. It is also found in its natural state in rock or soil. The inhalation of asbestos fibers into the lungs can result in a variety of adverse health effects, including inflammation of the lungs, respiratory ailments (e.g., asbestosis, a scarring of lung tissue that results in constricted breathing), and cancer (e.g., lung cancer and mesothelioma, a cancer of the linings of the lungs and abdomen).
2.2.6 Odors Offensive odors can be unpleasant and lead to citizen complaints to local governments and air districts. According to the Air Quality and Land Use Handbook: A Community Health Perspective (CARB 2005), land uses associated with odor complaints typically include sewage treatment plants, landfills, recycling facilities, manufacturing plants, and agricultural operations. CARB provides recommended screening distances for siting new receptors near existing odor sources.
2.3 Impacts and Mitigation Measures
2.3.1 Methodology Criteria pollutant emissions generated by construction activities were quantified using the California Emissions Estimator Model (CalEEMod), version 2022.1. Assumptions related to construction activity and scheduling (i.e., construction phase start and end dates) were based on project-specific information provided by the project sponsor and model defaults where project-specific information was not available. The data used in the construction analysis are provided in Attachment A of this report. Construction is expected to consist of eight main phases of construction activities. Phase 1 (rough grading/site demo) includes demolition of the buildings, site clearing, shoring, grading, and mass excavation, followed by Phase 2 (deep foundations), Phase 3 (foundations), Phase 4 (superstructure), Phase 5 (building enclosure), Phase 6 (interior buildout), Phase 7 (sitework), and Phase 8 (startup/building commissioning final inspections). Each phase has discrete start and end dates.2 Based on input from the project sponsor, the analysis assumes that construction would occur 5 days a week, Monday through Friday. The construction assumptions for the project are summarized below. In addition, the data used in the construction analysis are provided in Attachment A of this report.
2 The analysis assumed construction would begin in August 2023 and end in March 2026 (32 months). After the analysis was conducted, the construction schedule was updated to begin in May 2024 and end in February 2027 (33 months). Over time, construction vehicles and equipment fleets will get cleaner as regulations become more stringent and older, more polluting equipment is replaced by newer, cleaner equipment. In addition, by lengthening the overall construction schedule, daily and annual emissions will decrease because activities will occur over a longer time frame. Therefore, the analysis is conservative.

•Heavy-Duty Construction Equipment. The project sponsor provided information regardingthe number of pieces of equipment, fuel type, engine tier, and hours per day for each phase ofconstruction. Some equipment would be electrically powered, including the scissor lifts andmanlifts. All construction equipment would have a Tier 4 final engine, except for electricequipment, which does not produce direct emissions, and a diesel-powered drill rig, whichwould have a Tier 3 engine.
•Construction Workers’ Vehicle Trips. Emissions calculations were based on the CalEEModdefault number of daily workers per phase, number of trips per day (two one-way trips perworker), trip length (11 miles one way), and fleet mix (e.g., light-duty autos and light-dutytrucks). Emissions were calculated in CalEEMod using the vehicle emissions factors fromEMFAC2021.
•Construction Vendor Truck Trips. Emissions calculations were based on the number of dailyvendors per phase provided by the project sponsor, number of trips per day (two one-waytrips), trip length (7.3 miles one way), and fleet mix (e.g., heavy-heavy duty trucks, medium-heavy duty trucks). Emissions were calculated in CalEEMod using the vehicle emissions factorsfrom EMFAC2021.
•Construction Haul Truck Trips. Emissions calculations were based on the total number of haultrucks per phase provided by the project sponsor for rough grading/demolition, deepfoundations, foundations, superstructure, building enclosure, trip lengths, and fleet mix (e.g.,heavy-heavy duty trucks). The total numbers of truck trips for the construction phases werecalculated by multiplying the number of daily trips by the number of days for each constructionphase, respectively.
•Paving. Paving activities would result in the emissions of ROGs. An area of 0.50 acre on theproject site would be paved each day during the sitework phase.
•Architectural Coating. Architectural coating activities would result in emissions of ROGs. Theactivities would take place during building enclosure and interior buildout constructionactivities.
•Earthmoving. Earthmoving activities would result in emissions of particulate matter dust.Earthmoving activities include grading a maximum of 1.5 acres per day during the first phase(rough grading/site demolition) and 0.25 acre per day during the sitework phase. Soil would beexported and imported during the rough grading/site demolition phase and exported during thedeep foundations phase.
•Demolition. Removal of the existing structure would result in the emissions of particulatematter dust. A maximum of 25,000 sf of existing structure would be demolished per day andexported off-site during the demolition phase.It was assumed that BAAQMD basic construction mitigation measures would be implemented. The measures applicable to the proposed project are as follows (BAAQMD 2017a):
•All exposed surfaces (e.g., parking areas, staging areas, soil piles, graded areas, unpaved accessroads) shall be watered two times per day.
•All haul trucks transporting soil, sand, or other loose material off-site shall be covered.
•All visible mud or dirt track-out onto adjacent public roads shall be removed using wet powervacuum street sweepers at least once per day. The use of dry power sweeping is prohibited.
Chapter 2: Air Quality
Air Quality and Greenhouse Gas Technical Report Infinite 101 Project 2-18 June 2023 ICF 104667
•All vehicle speeds on unpaved roads shall be limited to 15 mph.
•All roadways, driveways, and sidewalks to be paved shall be completed as soon as possible.Building pads shall be laid as soon as possible after grading unless seeding or soil binders areused.
•Idling times shall be minimized either by shutting equipment off when not in use or reducing themaximum idling time to 5 minutes (as required by the California Airborne Toxics ControlMeasure, Title 13, CCR Section 2485). Clear signage shall be provided for construction workersat all access points.
•All construction equipment shall be maintained and properly tuned in accordance withmanufacturer’s specifications. All equipment shall be checked by a certified mechanic anddetermined to be running in proper condition prior to operation.
•A publicly visible sign shall be posted with the telephone number and name of the person tocontact at the lead agency regarding dust complaints. This person shall respond and takecorrective action within 48 hours. The air district’s phone number shall also be visible to ensurecompliance with applicable regulations.
2.3.2 Thresholds of Significance This analysis evaluates the impacts of regional emissions generated by the project using a two-tiered approach that considers guidance recommended by BAAQMD in the agency’s CEQA Guidelines (BAAQMD 2017a). First, this analysis considers whether the proposed project would conflict with the most recent air quality plan (BAAQMD 2017b). Specifically, the impact analysis evaluates whether the project would support the primary goals of the 2017 Clean Air Plan, including applicable control measures, and whether it would disrupt or hinder implementation of any control measures. Second, calculated regional criteria pollutant emissions are compared with BAAQMD’s project-level thresholds (BAAQMD 2017a).3 BAAQMD’s thresholds, as summarized in Table 4, are recommended by the agency to evaluate the significance of a project’s regional criteria pollutant emissions. According to BAAQMD, projects with emissions in excess of the thresholds shown in Table 4 would be expected to have a significant cumulative impact on regional air quality because an exceedance of the thresholds is anticipated to contribute to NAAQS and CAAQS violations.
Localized Project-Generated Criteria Pollutant Emissions (Carbon Monoxide and Particulate Matter) and Air Toxics (Diesel Particulate Matter) Localized pollutants generated by a project can be deposited near the emissions source, potentially affecting the nearby population. Although these pollutants dissipate with distance, emissions from individual projects can result in direct and material health impacts on adjacent sensitive receptors. The localized pollutants of concern that would be generated by the project are CO, PM, and DPM. The applicable thresholds for each pollutant are described below.
3 As noted above, BAAQMD adopted updated CEQA Guidelines in April 2023; however, those guidelines do not change the numerical criteria pollutant emissions thresholds from the 2017 CEQA Guidelines.

•Nitrogen oxides: Same as construction
•Particulate matter: 82 pounds/day
•Fine particulate matter: 54 pounds/daySource: BAAQMD 2017a.
Carbon Monoxide Heavy traffic congestion can contribute to high levels of CO. Individuals exposed to such “hot spots” may have a greater likelihood of developing adverse health effects. BAAQMD has adopted screening criteria that provide a conservative indication of whether project-generated traffic would cause a potential CO hot spot. If the screening criteria are not met, a quantitative analysis, through site-specific dispersion modeling of project-related CO concentrations, would not be necessary. A project would not cause localized violations of the CAAQS for CO if BAAQMD’s CO screening criteria, summarized below, are met (BAAQMD 2017a).
•The project traffic would not increase traffic volumes at affected intersections to more than44,000 vehicles per hour.
•The project traffic would not increase traffic volumes at affected intersections to more than24,000 vehicles per hour where vertical and/or horizontal mixing is substantially limited (e.g., atunnel, parking garage, bridge underpass, natural or urban street canyon, below-graderoadway).
•The project would be consistent with an applicable congestion management programestablished by the county congestion management agency for designated roads or highways, theregional transportation plan, and local congestion management agency plans.BAAQMD does not consider construction-generated CO to be a significant pollutant of concern because construction activities typically do not generate substantial quantities of this particular pollutant (BAAQMD 2017a).
Particulate Matter BAAQMD adopted an incremental PM2.5 concentration-based significance threshold in which a “substantial” contribution at the project level for an individual source is defined as total (i.e., exhaust and fugitive) PM2.5 concentrations exceeding 0.3 microgram per cubic meter (μg/m3). In addition, BAAQMD considers projects to have a cumulatively considerable PM2.5 impact if sensitive receptors are exposed to PM2.5 concentrations from local sources within 1,000 feet, including existing sources, project-related sources, and reasonably foreseeable future sources, that exceed 0.8 μg/m3 (BAAQMD 2017a).
Chapter 2: Air Quality
Air Quality and Greenhouse Gas Technical Report Infinite 101 Project 2-20 June 2023 ICF 104667
BAAQMD has not established PM10 thresholds of significance. BAAQMD’s PM2.5 thresholds apply to both new receptors and new sources. However, BAAQMD considers impacts related to fugitive PM10from earthmoving activities to be less than significant with application of BAAQMD’s basic construction mitigation measures.
Diesel Particle Matter DPM has been identified as a TAC. It is particularly concerning because long-term exposure can lead to cancer, birth defects, and damage to the brain and nervous systems. BAAQMD has adopted incremental cancer and hazard thresholds to evaluate receptor exposure to single sources of DPM emissions. The “substantial” DPM threshold defined by BAAQMD is exposure of a sensitive receptor to an individual emissions source, resulting in an excess cancer risk level of more than 10 in 1 million or a non-cancer (i.e., chronic or acute) hazard index greater than 1.0. BAAQMD also considers projects to have a cumulatively considerable DPM impact if they contribute to DPM emissions that, when combined with cumulative sources within 1,000 feet of sensitive receptors, result in excess cancer risk levels of more than 100 in 1 million or an hazard index greater than 10.0. BAAQMD considers projects to have a significant cumulative impact if they introduce new receptors at a location where the combined exposure to all cumulative sources within 1,000 feet is in excess of cumulative thresholds (BAAQMD 2017a).
Asbestos BAAQMD considers a project to have a significant impact if it does not comply with the applicable regulatory requirements outlined in BAAQMD’s Regulation 11, Rule 2.
Odors BAAQMD (BAAQMD 2017a) and CARB (CARB 2005) have identified several types of land uses as being commonly associated with odors, such as landfills, wastewater treatment facilities, and animal processing centers. BAAQMD’s CEQA Guidelines recommend that project analyses identify the location of existing and planned odor sources and include policies to reduce potential odor impacts in the project area.
2.3.3 Project Impacts
Applicable Air Quality Plan Consistency The CAA requires a SIP or an air quality control plan to be prepared for areas where air quality violates the NAAQS. The SIP sets forth the strategies and pollution control measures that states will use to attain the NAAQS. The CCAA requires attainment plans to demonstrate a 5 percent per year reduction in nonattainment air pollutants or their precursors, averaged every consecutive 3-year period, unless an approved alternative measure of progress is developed. Air quality attainment plans outline emissions limits and control measures to achieve and maintain the standards by the earliest practical date. The current air quality attainment plan for the SFBAAB is the 2017 Clean Air Plan (BAAQMD 2017a).
Chapter 2: Air Quality
Air Quality and Greenhouse Gas Technical Report Infinite 101 Project 2-21 June 2023 ICF 104667
Consistency with the Bay Area 2017 Clean Air Plan BAAQMD adopted their 2017 Clean Air Plan on April 19, 2017. The 2017 Clean Air Plan updates the prior 2010 Bay Area ozone plan and outlines feasible measures to reduce ozone; provides a control strategy to reduce particulate matter, air toxics, and GHGs in a single integrated plan; and establishes emissions control measures to be adopted or implemented. The 2017 Clean Air Plan is the most current applicable air quality plan for the air basin. Consistency with this plan is the basis for determining whether the proposed project would conflict with or obstruct implementation of an air quality plan. BAAQMD has adopted plan-level impact guidance to assist CEQA lead agencies in determining consistency with the 2010 Clean Air Plan, as outlined in BAAQMD’s CEQA Guidelines (BAAQMD 2017a). Since adoption of the CEQA Guidelines, the 2017 Clean Air Plan was adopted by BAAQMD. The consistency analysis is transferable to this latest air quality plan. BAAQMD recommends that the agency approving a project when an air quality plan consistency determination is required analyze the project with respect to the questions below. If all the questions are concluded in the affirmative, and those conclusions are supported by substantial evidence, BAAQMD considers the project consistent with the air quality plans prepared for the Bay Area. 1.Does the project support the primary goals of the air quality plan?The primary goals of the 2017 Clean Air Plan are (1) protect air quality and health at theregional and local scale—specifically, attain all state and national air quality standards andeliminate disparities among Bay Area communities with respect to the cancer health risk fromTACs and (2) protect the climate—specifically, reduce Bay Area GHG emissions to 40 percentbelow 1990 levels by 2030 and 80 percent below 1990 levels by 2050.The proposed project would support the primary goals of the 2017 Clean Air Plan. It proposes toredevelop a large parking lot and densify the area with the a multi-story R&D development. Inaddition, the nearest bus stop is within 0.5 mile at Herman Street and Pacific Avenue, whichwould encourage future employees to use public transportation.The proposed project would include sustainability features that would support a sustainablebuilding design and a reduction in GHG emissions. Specifically, the proposed project wouldinstall a photovoltaic (PV) roof canopy and provide continuous bike and pedestrian accessthroughout the campus. Furthermore, the proposed project would comply with all applicableCity and state measures, including Title 24, Part 6, of the California Energy Code baselinestandard requirements for energy efficiency.2.Does the project include applicable control measures from the air quality plan?To meet the primary goals, the 2017 Clean Air Plan recommends specific control measures andactions. These control measures are grouped into various categories and include stationarysource measures, mobile-source measures, and transportation control measures. The 2017Clean Air Plan recognizes that community design dictates individual travel mode and that a keylong-term control strategy to reduce emissions of criteria pollutants, air toxics, and GHGs frommotor vehicles is to channel future Bay Area growth into vibrant urban communities wheregoods and services are close at hand and people have a range of viable transportation options.To this end, the 2017 Clean Air Plan includes control measures that are aimed at reducing airpollution in the SFBAAB.
Chapter 2: Air Quality
Air Quality and Greenhouse Gas Technical Report Infinite 101 Project 2-22 June 2023 ICF 104667
The proposed project would include and support TR9: Bicycle and Pedestrian Access and Facilities. The project would improve conditions for walking and biking by providing on-site bicycle racks/lockers, providing long-term bicycle racks for workers, and orienting the buildings toward the sidewalk, with multiple pedestrian entrances. The proposed project would include and support TR22: Construction, Freight, and Farming Equipment. All off-road construction equipment associated with the project would include either electric, Tier 3, or Tier 4 engines. The proposed project would also support TR2: Trip Reduction Programs. The proposed project would comply with the City’s Transportation Demand Management (TDM) ordinance, reducing operational VMT and related criteria pollutant, air toxic, and GHG emissions. The proposed project would also support TCM-D3: Local Land Use Strategies. The proposed project would replace an existing parking structure with an employment center and be located within 0.5 mile of the bus stop at Herman Street and Pacific Avenue. This would encourage future employees to use public transportation. 3.Does the project disrupt or hinder implementation of any air quality plan control measures?The proposed project would not hinder implementation of any control measures in the 2017Clean Air Plan. Rather, the project supports and includes TR9: Bicycle and Pedestrian Access andTCM-D3: Local Land Use Strategies. Other control measures are not applicable to the project,such as those involving stationary sources or those that are policies for BAAQMD to adopt.Although these measures are not applicable to the project, the project would not hinder themeasures from being implemented.
Conclusion Based on the discussion above, the proposed project would support the primary goals of the 2017 Clean Air Plan, would incorporate all applicable control measures, and would not disrupt or hinder the implementation of any control measures. Thus, the proposed project would not conflict with or obstruct implementation of the 2017 Clean Air Plan.
Mass Emissions of Criteria Air Pollutant Impacts The mass emissions thresholds developed by BAAQMD to assess the potential for a project to violate the local air quality standards or contribute to an air quality standard violation correlate to the planned increases in air pollutant emissions that are assumed in the 2017 Clean Air Plan. According to BAAQMD, projects with emissions in excess of their thresholds would be expected to have a significant cumulative impact on regional air quality because an exceedance of the thresholds is anticipated to contribute to CAAQS and NAAQS violations.
Construction Impacts Project construction has the potential to create air quality impacts through the use of heavy-duty construction equipment, construction workers’ vehicle trips, on-road trips, paving, and the application of architectural coatings. In addition, fugitive dust emissions would result from the removal of existing structures and earthmoving activities. Emissions may vary substantially, depending on the level of activity, length of the individual construction activity, the types of equipment, number of personnel, and soil moisture content.
Chapter 2: Air Quality
Air Quality and Greenhouse Gas Technical Report Infinite 101 Project 2-23 June 2023 ICF 104667
Construction-related emissions for the proposed project have been calculated using the methods described above. To evaluate construction emissions, it was assumed that the BAAQMD’s fugitive dust control measures (i.e., 15 mph speed limit on unpaved roads and watering exposed soil during active construction twice per day) would be implemented, as required for all development occurring within BAAQMD’s jurisdiction, as well as the City’s standard conditions of approval.45 Estimated construction emissions for the project assume implementation of these measures. Emissions are summarized in Table 5 by the year in which construction would occur, and each year is compared individually to the applicable BAAQMD threshold. Emissions are presented by each year of construction to capture the sum of emissions from multiple activity categories occurring within the same year.

No No No No a.Emissions are rounded to the nearest whole number. b.Exceedances are underlined. c.The modeling output files are included in Attachment A of this report.d.Emissions reported in this table are based on implementation of BAAQMD’s fugitive dust control measures.e.The analysis assumed construction would begin in August 2023 and end in March 2026 (32 months). After theanalysis was conducted, the construction schedule was updated to begin in May 2024 and end in February 2027(33 months). Over time, construction vehicles and equipment fleets will get cleaner as regulations become more stringent and older, more polluting equipment is replaced by newer, cleaner equipment. Additionally, byexpanding the construction schedule, emissions will decrease per day and per year as activity will occur over a longer time frame. Therefore, the analysis is conservative.As shown in Table 5, emissions would be below the BAAQMD threshold for all pollutant emissions for all years, and, as noted above, best management practices (BMPs) during construction activities would be implemented in accordance with BAAQMD guidelines as well as the City’s standard conditions of approval. With implementation of BAAQMD’s fugitive dust control measures, further mitigation would not be required.
4 The City’s standard conditions of approval related to dust include Condition 12: The construction and permitted
use on the property shall be so conducted as to reduce to a minimum any noise, vibration, or dust resulting from
the operation. Also included is Condition 15. Prior to any on-site grading, a grading permit shall be obtained from the City Engineer. 5 Mitigation Measure AIR-1a in the City General Plan Update, Zoning Code Amendments, and Climate Action Plan Draft Program Environmental Impact Report states that individual development projects facilitated by the proposed project shall incorporate basic construction mitigation measures recommended by BAAQMD. By implementing BAAQMD best management practices, the proposed project would comply with Mitigation Measure AIR-1a.

Operational Impacts Operation of the proposed project would generate emissions associated primarily with mobile, energy, and stationary sources. Each of these sources was included in the quantification of the project’s long-term operational emissions, as described below.
Stationary-, Mobile-, and Area-Source Emissions The proposed project would result in stationary-source emissions from the operation of three emergency diesel generators, which would be used in the event of power grid failure. The generators would include Tier 2 engines. The proposed project would also result in mobile-source emissions associated with daily ongoing employee trips to and from the project site. Area-source emissions would occur during normal facility operation and maintenance. Lastly, Type II laboratory operations would emit ROG emissions. Area, energy, mobile, stationary, and laboratory sources of daily emissions are shown in Table 6 and compared to the applicable BAAQMD thresholds.

Peninsula Clean Energy uses 100% renewable sources to generate electricity.
Community Risk Impacts
Diesel Particulate Matter and Localized PM2.5 DPM is a carcinogen emitted by diesel internal-combustion engines. Construction activities would generate DPM (i.e., PM2.5 in exhaust from diesel-fueled vehicles)6 that could expose sensitive receptors to substantial health risks, beginning in 2023. DPM concentrations would be dramatically reduced, even at distances of 500 feet, as explained in BAAQMD’s CEQA Guidelines (BAAQMD 2017a): Due to the variable nature of construction activity, the generation of TAC emissions in most cases would be temporary, especially considering the short amount of time such equipment is typically within an influential distance that would result in the exposure of sensitive receptors to substantial concentrations. Concentrations of mobile-source diesel particulate matter emissions are typically
6 Per BAAQMD guidance, PM2.5 exhaust is used as a surrogate for DPM.
Chapter 2: Air Quality
Air Quality and Greenhouse Gas Technical Report Infinite 101 Project 2-25 June 2023 ICF 104667
reduced by 70 percent at a distance of approximately 500 feet. In addition, current models and methodologies for conducting health risk assessments are associated with longer-term exposure periods of 9, 40, and 70 years, which do not correlate well with the temporary and highly variable nature of construction activities. This results in difficulties with producing accurate estimates of health risks. BAAQMD has determined that construction and operational sources of DPM and PM2.5 occurring at distances of more than 1,000 feet from a sensitive receptor most likely do not pose a significant health risk. There are no sensitive receptors within 1,000 feet of the project site. The nearest sensitive receptors are residential uses approximately 1,700 feet to the southwest. Therefore, health risks from construction and operational emissions of DPM and PM2.5 would be less than all BAAQMD-recommended health risk thresholds. Consequently, construction and operational emissions of DPM and PM2.5 would not expose sensitive receptors to substantial pollutant concentrations.
Laboratory TACs Project buildings could have wet laboratory uses that, depending on the specific use, could generate emissions from building vents. Although the exact emissions and TACs that could occur are unknown, examples of common TACs from laboratories include benzene, t-butyl alcohol, chloroform, ethanol, and formaldehyde. The precise use of new laboratory space is unknown at this time, but this assessment conservatively assumes that 50 percent of the new buildings could have laboratories, resulting in a maximum of 334,507 sf of wet laboratory space. However, during the building permitting phase of development, if any new stationary TAC sources are constructed, compliance with BAAQMD rules and regulations would be required, ensuring that new sources would be in compliance with regulations regarding best available control technology, if appropriate, which could include emissions limits and/or emissions control technologies appropriate for the specific source. Similar to the discussion in the section above, there are no sensitive receptors within 1,000 feet of the project site. As such, operational emissions of laboratory-generated TACs would not expose sensitive receptors to substantial pollutant concentrations.
Localized Carbon Monoxide Impacts Continuous engine exhaust may elevate localized CO concentrations, resulting in “hot spots.” Receptors exposed to these CO hot spots may have a greater likelihood of developing adverse health effects. CO hot spots are typically observed at heavily congested intersections where a substantial number of gasoline-powered vehicles idle for prolonged durations throughout the day. BAAQMD’s screening criteria for CO hot spots is 44,000 vehicles per hour at affected intersections or 24,000 vehicles per hour at affected intersections where vertical or horizontal mixing is limited (i.e., a tunnel). In order to use BAAQMD’s quantitative screening criteria to evaluate CO hot spots, a project must be consistent with an applicable congestion management program (CMP). The project would not conflict with the applicable CMP because none of the study intersections are part of the CMP network. Thus, BAAQMD quantitative screening values are used to evaluate the project’s potential to create CO hot spots. Peak-hour traffic volume data at the intersections in the project area, provided by the traffic engineers, indicate that volumes at all intersections would be below both the 44,000- and 24,000-vehicle-per-hour levels (Hawkins pers. comm.). As a result, the additional vehicle trips associated with the project would not result in a localized violation of the CAAQS for CO.
Chapter 2: Air Quality
Air Quality and Greenhouse Gas Technical Report Infinite 101 Project 2-26 June 2023 ICF 104667
Odor Impacts Offensive odors rarely cause physical harm, but they can be unpleasant and lead to considerable distress among the public. This distress often generates citizen complaints to local governments and air districts. According to CARB’s 2005 Air Quality and Land Use Handbook: A Community Health
Perspective, land uses associated with odor complaints typically include sewage treatment plants, landfills, recycling facilities, manufacturing plants, and agricultural operations (CARB 2005). CARB provides recommended screening distances for siting new receptors near existing odor sources. The project would not site any new sensitive receptors near an existing odor source because the project would not include sensitive land uses (e.g., schools or residences). BAAQMD’s Regulation 7 (Odorous Substances) establishes general odor limitations on odorous substances and specific emissions limitations on certain odorous compounds. The proposed project would be constructed on land designated as Business Technology Park-High. The project, a R&D center, is a land use that is not typically associated with odor complaints, based on CARB’s Air Quality and Land Use Handbook: A Community Health Perspective. During construction, diesel-powered equipment, exhaust from haul vehicles, and architectural coatings may generate temporary odors. During project operations, startup and maintenance testing of emergency generators may also result in temporary odors. Both construction equipment- and generator-related odors would be temporary and would dissipate rapidly as a function of distance. The nearest sensitive receptors are more than 1,000 feet from the project site; at this distance, the odors would most likely not be strong enough to be considered offensive. When compared with existing odor sources in the vicinity of the project site, including industrial land uses, odor impacts from project operations would be similar to current conditions. The proposed project would comply, as applicable, with BAAQMD’s Regulation 7, which limits emissions of odorous compounds from all non-exempt entities within BAAQMD jurisdiction. Accordingly, construction and operation of the project is not expected to create objectionable odors that would affect a substantial amount of people.
2.3.4 Cumulative Impacts on Air Quality In developing thresholds of significance for air pollutants, BAAQMD considered the emissions levels for which a project’s individual emissions would be cumulatively considerable. If a project would not exceed the identified significance thresholds, its emissions would not be cumulatively considerable, resulting in less-than-significant air quality impacts on the region’s existing air quality conditions. As noted above under Construction Impacts, construction of the project would include BAAQMD’s fugitive dust control measures; neither construction nor operation of the project would result in ROG, NOX, or PM emissions in excess of BAAQMD’s numeric thresholds (see Table 4). Accordingly, implementation of the project would not result in a cumulatively considerable impact with respect to ROG, NOX, or PM emissions. With respect to community risk impacts, as noted above, sources of DPM and PM2.5 occurring at distances of more than 1,000 feet from a sensitive receptor most likely do not pose a significant health risk. There are no sensitive receptors within 1,000 feet of the project site, and thus, for the reasons described above for the project-level analysis, cumulative impacts related to pollutant exposure would also not be substantial. Consequently, the project would not expose sensitive receptors to substantial pollutant concentrations that would result in a cumulatively considerable impact.

Chapter 3 Greenhouse Gases and Climate Change
3.1 Regulatory Setting GHG emissions are addressed by the plans, policies, laws, and regulations of various federal, state, regional, and local government agencies, as presented in greater detail below.
3.1.1 Federal Several federal EOs have recently been signed by President Biden related to GHG emissions and climate resiliency. EO 13990, signed in January 2021, set a national goal to achieve a 50 to 52 percent reduction in economy-wide net GHG pollution from 2005 levels in 2030. EO 14057, signed in December 2021, requires federal agencies to develop strategic processes for achieving, among other things, carbon-free electricity by 2030 and 100 percent zero-emission vehicle acquisitions by 2035. President Biden has also signed two bills—Infrastructure Investment and Jobs Act (2021) and Inflation Reduction Act (2022)—that provide funding for infrastructure improvements that will reduce GHG emissions and bolster resilience to climate change. Despite these actions, there is currently no federal overarching law specifically related to climate change or reductions in GHG emissions. Under the Obama administration, EPA had been developing regulations under the CAA. There have also been settlement agreements between EPA, several states, and nongovernmental organizations to address GHG emissions from electric generating units and refineries, in addition to EPA’s issuance of an endangerment finding and a cause or contribute finding. EPA has also adopted the Mandatory Reporting Rule and Clean Power Plan. Under the Clean Power Plan, EPA issued regulations to control carbon dioxide (CO2) emissions from new and existing coal-fired power plants.
Vehicle Emissions Standards NHTSA and EPA set CAFE standards for passenger cars and for light trucks (collectively, light-duty vehicles), and separately set fuel consumption standards for medium- and heavy-duty trucks and engines. The current CAFE standards require an industry-wide fleet average of approximately 49 mpg for passenger cars and light trucks in model year 2026 by increasing fuel efficiency by 8 percent annually for model years 2024 and 2025 and 10 percent annually for model year 2026. Phase 2 of the Greenhouse Gas Emissions Standards and Fuel Efficiency Standards for Medium- and Heavy-Duty Engines and Vehicles applies to medium- and heavy-duty vehicles, model years 2019 through 2027. On April 12, 2023, EPA proposed two new federal vehicle standards that will build on the existing CAFE and Phase 2 standards. Multi-Pollutant Emissions Standards for Model Years 2027 and Later Light-Duty and Medium Duty Vehicles proposes more stringent emission standards for light-duty and medium-duty vehicles for model years 2027 through 2032 and accelerates the deployment of electric- and clean-vehicles. Greenhouse Gas Standards for Heavy-Duty Vehicles – Phase 3 establishes fleet mix performance standards for vocational vehicles (e.g., delivery trucks) and trucks that are typically used to haul freight.

3.1.2 State
Statewide GHG Emission Targets and the Climate Change Scoping Plan GHG emission targets established by the state legislature include reducing statewide GHG emissions to 1990 levels by 2020 (AB 32 of 2006) and reducing them to 40 percent below 1990 levels by 2030 (Senate Bill [SB] 32 of 2016). EO S-3-05 calls for statewide GHG emissions to be reduced to 80 percent below 1990 levels by 2050. EO B-55-18 calls for California to achieve carbon neutrality by 2045 and achieve and maintain net-negative GHG emissions thereafter. These targets are in line with the scientifically established levels needed in the United States to limit the rise in global temperature to no more than 2 degrees Celsius (°C), the warming threshold at which major climate disruptions, such as super droughts and rising sea levels, are projected; these targets also pursue efforts to limit the temperature increase even further to 1.5°C (United Nations 2015). California’s 2017 Climate Change Scoping Plan, prepared by CARB, outlines the main strategies California will implement to achieve the legislated GHG emission target for 2030 and “substantially advance toward our 2050 climate goals” (CARB 2017). It identifies the reductions needed by each GHG emissions sector (e.g., transportation, industry, electricity generation, agriculture, commercial and residential, pollutants with high global warming potential, recycling and waste). In November 2022, CARB adopted the 2022 Scoping Plan Update, which identifies a technologically feasible and equity-focused pathway for the state to achieve carbon neutrality by 2045. The 2022 update outlines three alternatives for meeting the state’s climate goals. Two different alternatives would achieve carbon neutrality by 2035, which would require acceleration of the 2030 and 2045 GHG goal. A third alternative identifies a pathway to attain carbon neutrality by 2045 (CARB 2022c). The state has also passed more detailed legislation for addressing GHG emissions associated with industrial sources, transportation, water conservation, building energy efficiency, solid waste, electricity generation, and energy consumption, as summarized below.
Legislation Addressing Electricity Generation The state has passed legislation requiring the increasing use of renewables to produce electricity for consumers. California utilities are required to generate 33 percent of their electricity from renewables by 2020 (SB X1-2 of 2011), 52 percent by 2027 (California Renewables Portfolio Standard [RPS] Program [SB 100 of 2018]), 60 percent by 2030 (also SB 100 of 2018), and 100 percent by 2045 (also SB 100 of 2018). SB 1368 of 2006 required the California Public Utilities Commission (CPUC) to establish a GHG-emissions performance standard for baseload generation from investor-owned utilities by February 1, 2007. The California Energy Commission (CEC) was also required to establish a similar standard for local publicly owned utilities by June 30, 2007. These standards cannot exceed the GHG emission rate from a baseload combined-cycle natural gas–fired plant. The standard is set at a level of GHG emissions equal to those of a combined-cycle natural-gas plant on a per megawatt-hour (MWh) basis, or 1,100 pounds of CO2 per MWh (0.5 metric ton of carbon dioxide equivalent [MTCO2e]/MWh) (CPUC 2007). CPUC’s analysis showed an emission factor of 0.337 MTCO2e/MWh for 2020 (CPUC 2021). The legislation further requires that all electricity provided to California, including imported electricity, must be generated from plants that meet the standards set by CPUC and CEC.

California Energy Efficiency Standards for Residential and Nonresidential Buildings—Green Building Code, Title 24 Update The Green Building Standards Code (CALGreen) applies to the planning, design, operation, construction, use, and occupancy of newly constructed buildings and requires the installation of energy- and water-efficient indoor infrastructure for all new projects after January 1, 2011. CALGreen also requires newly constructed buildings to develop a waste management plan and divert at least 50 percent of the construction materials generated during project construction. Administrative regulations related to CALGreen Part 11 and the 2016 Building Energy Efficiency Standards were adopted in 2016 (effective January 1, 2017). The 2016 standards resulted in residential construction that was 25 percent more efficient than previous residential construction. Part 11 also established voluntary standards, which became mandatory in the 2010 edition of the code, including planning and designing for sustainable site development, energy efficiency, water conservation, material conservation, and reductions in internal air contaminants. The standards offer builders better windows, insulation, lighting, ventilation systems, and other features to reduce energy consumption in homes and businesses. In August 2021, the CEC adopted the 2022 Building Energy Efficiency Standards, which took effect on January 1, 2023. The 2022 residential standards encourage builders to install heat pumps instead of gas-fueled units for heating, ventilation, and air-conditioning; require homes to be “electric ready” for appliances; increase minimum kitchen ventilation requirements; and allow exceptions to existing solar PV standards for smaller homes. The 2022 non-residential standards establish combined solar PV and battery standards for select businesses, establish new efficiency standards for commercial greenhouses, and improve efficiency standards for building envelope, internal systems, and grid integration equipment (California Energy Commission 2021).
Assembly Bill 1279 AB 1279 (Health and Safety Code Section 38562.2) requires California to achieve net-zero GHG emissions (i.e., reach a balance between the GHGs emitted and removed from the atmosphere) no later than 2045 and maintain net-negative GHG emissions from then on. It also mandates an 85 percent reduction in statewide anthropogenic GHG emissions (from 1990 levels) by 2045. AB 1279 recognizes that meeting these targets requires direct GHG emission reductions and removal of CO2 from the atmosphere as well as a nearly complete transition from fossil fuels. As such, the bill directs CARB to work with relevant state agencies to ensure scoping plan updates include measures that put California on a trajectory to achieve these targets. It also tasks CARB with implementing strategies that facilitate CO2 removal solutions and carbon capture, utilization, and storage technologies. To evaluate the state’s progress, AB 1279 requires that CARB report progress toward these targets to the legislature annually. By 2035, the bill directs CARB to assess the feasibility and tradeoffs of reducing statewide anthropogenic GHG emissions to 85 percent below 1990 levels by 2045 and report its findings to the legislature.
Fuel Efficiency Standards for Light-Duty Passenger Vehicles AB 1493 of 2002 (Pavley I) required CARB to develop and implement regulations to reduce automobile and light-truck GHG emissions. These stricter emissions standards were designed to apply to automobiles and light trucks beginning with the model year 2009. Additional strengthening of the Pavley standards (referred to previously as Pavley II and now referred to as
Chapter 3: Greenhouse Gases and Climate Change
Air Quality and Greenhouse Gas Technical Report Infinite 101 Project 3-4 June 2023 ICF 104667
the Advanced Clean Cars measure) was adopted for vehicle model years 2017–2025 in 2012. Together, the two standards were expected to increase average fuel economy to roughly 54.5 mpg in 2025. As described in Section 2.1.1, Federal, in the SAFE Vehicles Rule, NHTSA and EPA proposed to amend the current fuel-efficiency standards for passenger cars and light trucks and establish new standards covering model years 2021–2026 by maintaining the current 2020 standards through 2026. California, 22 other states, the District of Columbia, and two cities filed suit against the proposed action on September 20, 2019 (California et al. v. United States Department of Transportation et al., 1:19-cv-02826, U.S. District Court for the District of Columbia). The lawsuit requests a “permanent injunction prohibiting Defendants from implementing or relying on the Preemption Regulation,” but does not stay its implementation during legal deliberations. Part One of the SAFE Vehicles Rule went into effect on November 26, 2019, and Part Two went into effect on March 30, 2020. On January 20, 2021, the president issued an EO that directed NHTSA and EPA to review the SAFE Vehicles Rule, Part One, and propose a new rule for suspending, revising, or rescinding it by April 2021. The EO also required NHTSA and EPA to propose a new rule for suspending, revising, or rescinding Part Two by July 2021. On December 12, 2021, NHTSA repealed the SAFE Vehicles Rule, Part One. On December 19, 2021, NHTSA finalized its vehicle efficiency standards rule to reach a projected industrywide target of 40 mpg by 2026, an approximately 25 percent increase over the prior SAFE Vehicles Rule. Lastly, on March 9, 2022, EPA reinstated California’s authority under the CAA to implement its own GHG emissions standards and sales mandate regarding zero-emission vehicles. This action concluded EPA’s reconsideration of 2019’s SAFE Vehicles Rule, Part One, by finding that actions under the previous administration, as part of SAFE-1, were decided in error; the actions are now rescinded.
Tractor-Trailer Greenhouse Gas Regulation In 2013, CARB approved the Tractor-Trailer Greenhouse Gas Regulation to reduce GHG emissions by requiring the use of aerodynamic tractors and trailers with low-rolling-resistance tires. The regulation applies to certain Class 8 tractors manufactured for use in California and is paralleled with EPA and NHTSA heavy-duty truck standards. This regulation was expected to reduce fuel consumption and GHG emissions from new heavy-duty trucks between 4 and 5 percent per year between 2014 and 2018 (EPA 2015).
Low Carbon Fuel Standard CARB adopted the Low-Carbon Fuel Standard (LCFS) in 2007 to reduce the carbon intensity of California’s transportation fuels. The LCFS applies to fuels used by on-road motor vehicles and off-road vehicles, including construction equipment. Note that the majority of emissions benefits associated with the LCFS come from the fuel production cycle (i.e., upstream emissions) rather than the combustion cycle (i.e., tailpipe). As a result, LCFS-related reductions are not included in this analysis of combustion-related emissions of CO2.
Regional Land Use and Transportation Planning Requirements In addition to regulations that address tailpipe emissions and transportation fuels, the state legislature has passed regulations to address the number of miles driven in light-duty passenger vehicles. Since the passage of SB 375 in 2008, CARB requires metropolitan planning organizations
Chapter 3: Greenhouse Gases and Climate Change
Air Quality and Greenhouse Gas Technical Report Infinite 101 Project 3-5 June 2023 ICF 104667
(MPOs) to adopt plans showing reductions in GHG emissions from passenger cars and light trucks in their respective regions for 2020 and 2035 (CARB 2018). If regions develop integrated land use, housing, and transportation plans that meet the SB 375 targets, new projects in these regions can be relieved of certain CEQA review requirements.
CEQA Requirements to Assess Vehicle Miles Traveled Under SB 743 of 2013, the Governor’s Office of Planning and Research (OPR) proposed changes to the CEQA Guidelines to require that CEQA transportation analyses move away from focusing on vehicle delay and level of service (LOS) and instead focus on VMT. The intent behind SB 743 is to integrate and balance congestion management, infill development, active transportation with GHG emissions reductions. These changes were adopted by the California Natural Resources Agency, resulting in the addition of Section 15064.3. In support of these changes, OPR published its Technical
Advisory on Evaluating Transportation Impacts in CEQA, which recommends that the transportation impact of a project be based on whether the project would generate a level of VMT per capita (or VMT per employee) that is 15 percent lower than that of existing development in the region. OPR’s technical advisory explains that this criterion is consistent with Section 21099 of the California Public Resources Code, which states that the criteria for determining significance must “promote the reduction in greenhouse gas emissions” (OPR 2017). This metric replaces the use of delay and LOS to measure transportation-related impacts.
Short-Lived Climate Pollutant Strategy CARB adopted the Short-Lived Climate Pollutant (SLCP) Reduction Strategy in March 2017 as a framework for achieving the methane (CH4), hydrofluorocarbon (HFC), and anthropogenic black carbon reduction targets set by SB 1383. The SLCP Reduction Strategy includes 10 measures that fit within a wide range of ongoing planning efforts throughout the state, including CARB’s and the California Department of Resources Recycling and Recovery’s (CalRecycle’s) proposed rulemaking on organic waste diversion (discussed below). SB 1383 requires that the state implement a comprehensive SLCP strategy to reduce statewide emissions of CH4 by 40 percent, HFC by 40 percent, and anthropogenic black carbon by 50 percent with respect to 2013 levels by 2030. CH4 emissions reduction goals include a target to reduce statewide landfill disposal of organics by 50 percent below 2014 levels by 2020 and 75 percent below 2014 levels by 2025.
Regulation for Reducing Sulfur Hexafluoride Emissions from Gas-Insulated Switchgear In 2010, CARB adopted the Regulation for Reducing Sulfur Hexafluoride Emissions from Gas Insulated Switchgear (Section 17 CCR 95350 et seq.). This regulation aims to achieve GHG reductions by reducing sulfur hexafluoride (SF6) emissions from gas-insulated switchgear. Owners of such switchgear must not exceed a maximum allowable annual emission rate of 1.0 percent. Owners must regularly inventory their gas-insulated switchgear equipment, measure quantities of SF6, and maintain monitoring records for at least 3 years. In addition, owners must report SF6 emissions annually to CARB. In September 2020, CARB adopted Resolution 20-28 to amend the current regulation to phase out acquisition of SF6 in gas-insulated switchgear in stages between 2025 and 2033. Under this resolution, CARB would be developing a timeline for phasing out SF6 equipment in California and creating incentives for encourage owners to replace SF6 equipment. The resolution was approved by the California Office of Administrative Law on December 30, 2021 (CARB 2022d).

3.1.3 Local
Metropolitan Transportation Commission The Metropolitan Transportation Commission (MTC) is the metropolitan planning organization for the nine counties that make up the Bay Area and the SFBAAB, which includes the city of South San Francisco. The first per capita GHG emissions reduction targets for the SFBAAB were 7 percent below 2005 levels by 2020 and 15 percent below by 2035. The per capita GHG emissions reductions targets for the SFBAAB have been revised to 10 percent by 2020 and 19 percent by 2035 (CARB 2018). MTC adopted a Sustainable Communities Strategy (SCS) as part of its Regional Transportation Plan (RTP) for the SFBAAB in 2021, known as Plan Bay Area 2050 (Metropolitan Transportation Commission and Association of Bay Area Governments 2021). Plan Bay Area 2050 includes transportation and environmental strategies that support active and shared modes of travel combined with a transit-supportive land use pattern that places housing near transportation centers. Implementation of these strategies is forecast to lower the number of Bay Area residents who drive to work alone from 50 percent in 2015 to 33 percent in 2050. This would lead to a 20 percent decrease in GHG emissions compared to 2005, meeting the state mandate of a 19 percent decrease in GHG emissions by 2050.
Bay Area Air Quality Management District BAAQMD is the primary agency responsible for addressing air quality concerns in the San Francisco Bay Area, including San Mateo County. Its role is discussed further in Chapter 2, Air Quality. BAAQMD recommends methods for analyzing project-related GHGs in CEQA analyses as well as multiple GHG reduction measures for land use development projects. BAAQMD released its justification report, CEQA Thresholds for Evaluating the Significance of Climate
Impacts from Land Use Projects and Plans (BAAQMD Justification Report), in April 2022 (Bay Area Air Quality Management District 2022). The BAAQMD Justification Report presents updates to the CEQA GHG thresholds from the 2017 CEQA Guidelines, which were not consistent with the statewide GHG target established by SB 32. These new GHG thresholds of significance were updated to consider newer state reduction targets (e.g., SB 32) and eventual carbon neutrality by 2045 (e.g., EO B-55-18) as well as evolving case law. In summary, the updated thresholds emphasize (1) avoidingwasting electricity and developing fossil fuel infrastructure in new buildings that will be in place fordecades and thus conflict with carbon neutrality by 2045, (2) compliance with CALGreen Tier 2electric-vehicle requirements and per capita VMT reductions consistent with SB 743, and (3)consistency with a qualified greenhouse reduction strategy, also known as a Climate Action Plan(CAP).
City of South San Francisco Climate Action Plan The City CAP was adopted in 2022 to reduce community and municipal GHG emissions. The CAP is a roadmap that outlines a path for the City to use to achieve its community-wide per-service-population GHG emissions reduction goal of 40 percent below 1990 levels by 2030, 80 percent below 1990 levels by 2040, and carbon neutrality by 2045 (City of South San Francisco 2022b). The CAP features 62 recommended GHG emissions reduction measures within seven sectors of community and municipal operations (i.e., clean energy, built environment – new construction, built environment – existing, transportation and land use, solid waste, water and wastewater, carbon sequestration and natural systems, city leadership).

Shape South San Francisco 2040 General Plan The following GHG-related goals from the General Plan (City of South San Francisco 2022a) are applicable to the proposed project:
Goal CP-1: A carbon neutral community by 2045.
Goal CP-2: A resilient and fossil-fuel-free energy system.
Goal CP-3: Green buildings are the standard in South San Francisco for new construction and major renovations.
Goal CP-6: The City continues to divert organics from landfill in accordance with state targets.
Goal CR-1: The City proactively advances community resilience and is prepared for all hazards, including climate disruption.
Goal CR-2: A resilient community that protects existing and future development and people from sea-level rise and flooding.
Goal ES-1: The City supports nature in South San Francisco to encourage healthy ecosystems, improve air and water quality, improve public health, and adapt to a changing climate.
Goal ES-5: Landscape design standards for new development enhance habitat quality, reduce water use, and support a diverse ecosystem.
Goal MOB-4: South San Francisco’s land use and transportation actions reduce VMT and GHG emissions.
Goal PE-4: Infrastructure investments support job access, job growth, and address climate hazards that affect South San Francisco businesses.
Goal SA-27: There are safe, comfortable, and accessible pedestrian and bicycle facilities that connect people to downtown, El Camino, and East of 101.
Transportation Demand Management Ordinance The City’s TDM ordinance requires projects to incorporate measures to reduce the number of trips generated and achieve goals related to the use of alternative modes. According to the ordinance, a project that is categorized as a Tier 4 project (i.e., office and R&D uses with at least 400,000 sf of gross floor area) must implement trip reduction measures with a total worth of at least 50 points, based on the City Planning Department’s table of measures and point values; annual monitoring to achieve a maximum of 50 percent of employees commuting while driving alone; and annual monitoring of a site-specific trip cap.7 The ordinance requires an annual employee mode-share survey at the project site to ensure that desired transportation mode shares are achieved. Where the mode share target is not achieved, City officials may require program modifications to increase alternative mode share or impose administrative penalties.

3.2 Existing Setting
3.2.1 Physical Scientific Basis of Greenhouse Gas and Climate Change Certain gases in the Earth’s atmosphere, classified as GHGs, play a critical role in determining the Earth’s surface temperature. Solar radiation enters the atmosphere from space. A portion of the radiation is absorbed by the Earth’s surface, and a smaller portion of this radiation is reflected toward space. The absorbed radiation is then emitted from the Earth as low-frequency infrared radiation. The frequencies at which bodies emit radiation are proportional to temperature. The Earth has a much lower temperature than the sun; therefore, the earth Emits lower-frequency radiation. Most solar radiation passes through GHGs; however, infrared radiation is absorbed by these gases. As a result, radiation that otherwise would have escaped back into space is instead “trapped,” resulting in a warming of the atmosphere. This phenomenon, known as the greenhouse
effect, is responsible for maintaining a habitable climate on Earth. Prominent GHGs contributing to the greenhouse effect are CO2, CH4, nitrous oxide (N2O), HFCs, perfluorocarbons (PFCs), and SF6. These six gases are also identified as GHGs in Section 15364.5 of the CEQA Guidelines. Human-caused emissions of these GHGs in excess of natural ambient concentrations are found to be responsible for intensifying the greenhouse effect and leading to a trend of unnatural warming of the Earth’s climate, known as global climate change or global
warming. It is “extremely likely” that more than half of the observed increase in global average surface temperature from 1951 to 2010 was caused by the anthropogenic increase in GHG concentrations and other anthropogenic forcing (Intergovernmental Panel on Climate Change [IPCC] 2014). Since the Industrial Revolution (1760–1840), increases in fossil-fuel combustion and deforestation have exponentially increased concentrations of GHGs in the atmosphere. Rising atmospheric concentrations of GHGs in excess of natural levels enhance the greenhouse effect, which contributes to global warming of the Earth’s lower atmosphere. This warming induces large-scale changes in ocean-circulation patterns, precipitation patterns, global ice cover, biological distributions, and other changes to the Earth’s system that are collectively referred to as climate change. Climate change is a global problem. GHGs are global pollutants, unlike criteria air pollutants and TACs, which are pollutants of regional and local concern. Whereas most pollutants with localized air quality effects have relatively short atmospheric lifetimes (approximately 1 day), GHGs have long atmospheric lifetimes (1 year to several thousand years). GHGs persist in the atmosphere long enough to be dispersed around the globe. Although the lifetime of any GHG molecule depends on multiple variables and cannot be determined with any certainty, it is understood that more CO2 is emitted into the atmosphere than is removed from the atmosphere (i.e., sequestered) by ocean uptake, vegetation, and other forms of sequestration. Of the total annual human-caused CO2 emissions, approximately 55 percent are estimated to be sequestered through ocean and land uptake every year, averaged over the last 50 years, whereas the remaining 45 percent of human-caused CO2 emissions remain stored in the atmosphere (IPCC 2013). No single project alone would measurably contribute to an incremental change in the global average temperature or to global or local climates or microclimates. From the standpoint of CEQA, GHG impacts relative to global climate change are inherently cumulative.

Air Quality and Greenhouse Gas Technical Report Infinite 101 Project 3-9 June 2023 ICF 104667
3.2.2 Principal Greenhouse Gases The GHGs listed by the Intergovernmental Panel on Climate Change (IPCC), CO2, CH4, N2O, HFCs, PFCs, and SF6 (IPCC 2014), are discussed in this section in order of abundance in the atmosphere, and the principal characteristics surrounding these pollutants are discussed below. California law and the CEQA Guidelines contain a similar definition of GHGs (Health and Safety Code Section 38505[g]; 14 CCR 15364.5). Water vapor, the most abundant GHG, is not included in this list because its natural concentrations and fluctuations far outweigh its anthropogenic sources. Consequently, the primary GHGs of concern associated with the proposed project are CO2, CH4, N2O, and SF6. Note that HFCs and PFCs are not discussed because those gases would be insignificant or are generated primarily by processes that are not anticipated as part of the proposed project.
•CO2 enters the atmosphere through the burning of fossil fuels (e.g., oil, natural gas, coal), solidwaste, and trees and wood products. It also results from respiration and chemical reactions(e.g., those associated with manufacturing cement). CO2 is sequestered when it is absorbed byplants as part of the biological carbon cycle.
•CH4 is emitted during the production and transport of coal, natural gas, and oil. It also resultsfrom livestock emanations and agricultural practices as well as the decay of organic waste inmunicipal solid-waste landfills.
•N2O is emitted during agricultural and industrial activities as well as during combustion of fossilfuels and solid waste.
•SF6 is used in gas-insulated switchgear and emitted from leaks.Methods have been set forth to describe emissions of GHGs in terms of a single gas to simplify reporting and analysis. The most commonly accepted method to compare GHG emissions is the global warming potential (GWP) methodology, as defined by the IPCC (IPCC 2007). IPCC defines the GWP of various GHG emissions on a normalized scale that recasts all GHG emissions in terms of carbon dioxide equivalent (CO2e), which compares the gas in question to that of the same mass of CO2 (which has a GWP of 1, by definition). The GWP values used in this report are based on the IPCC Fourth Assessment Report and United Nations Framework Convention on Climate Change reporting guidelines, as defined in Table 7 (IPCC 2007). The Fourth Assessment Report GWP values are consistent with those used in CARB’s 2020 California GHG inventory (CARB 2022e) and California’s 2022 Climate Change Scoping Plan (CARB 2022c).

3.2.3 Greenhouse Gas Inventory A GHG inventory is a quantification of all GHG emissions within a selected physical and/or economic boundary. GHG inventories can be performed on a large scale (e.g., for global and national entities) or on a small scale (e.g., for a particular building or person). Although many emissions processes are difficult to evaluate, several agencies have developed tools to quantify emissions from certain sources. As discussed previously, GHG emissions are attributable in large part to human activities. The total GHG inventory for California in 2020 was 369.2 million MMTCO2e (CARB 2022f). This is nearly 62 MMTCO2e less than the 2020 target of 431 MMTCO2e. Table 8 summarizes a breakdown of the statewide GHG inventory for California.
Table 8. Statewide Greenhouse Gas Emissions by Economic Sector for 2020a
Sector Percent Transportation 38 Industrial 23 Electricity generation (in state) 11 Electricity generation (imports) 5 Agriculture 9 Residential 9 Commercial 6 Source: CARB 2022f.a.The total emissions inventory for California in 2020 was 369.2 million metric tons of carbon dioxide equivalent.
Based on the breakdown shown in Table 8, the commercial sector in California accounts for approximately 6 percent of the state’s GHG emissions.
3.3 Impacts and Mitigation Measures
3.3.1 Methodology
Construction Activities Construction GHG emissions were quantified using the same methods described for the analysis of criteria pollutant emissions. Indirect GHG emissions would also occur from the use of electricity during construction. Electricity-related emissions would be generated from construction equipment and mobile offices, totaling 6,581 MWh, based on input from the project sponsor (Metz pers. comm.; Steenson pers. comm.). Peninsula Clean Energy (PCE) provides electrical service to the project site. Since 2021, PCE has provided 100 percent carbon-free electricity to its customers; as such, there would be no indirect GHG emissions from the use of electricity during construction.
Chapter 3: Greenhouse Gases and Climate Change
Air Quality and Greenhouse Gas Technical Report Infinite 101 Project 3-11 June 2023 ICF 104667
Operations Operational GHG emissions were generally quantified using the same methods described for the analysis of criteria pollutant emissions outlined above. Further assumptions were necessary to evaluate the additional emissions associated with indirect electricity consumption, water consumption, and solid waste generation. Assumptions related to operational activity were based on project-specific information provided by the project sponsor and model defaults where project specific information was not available. Additional operational assumptions unique to the analysis of GHG emissions are provided below.
Energy Based on input from the project applicant, the project would consume approximately 25,536,162 kilowatt-hours (kWh) of electricity per year (Metz pers. comm.). This estimate includes electricity use from the project building and the enclosed parking garage.
Water and Wastewater Water consumption requires electricity to supply, pre-treat, and distribute the water prior to its being consumed as well as treat the subsequent wastewater. The electricity consumed for these water processes results in indirect GHG emissions. Based on information from the project applicant, approximately 18,091,955 gallons of water per year would be used indoors, and 499,685 gallons of water per year would be used outdoors (Metz pers. comm.; Steenson pers. comm.).
Waste Based on input from the project applicant, the project would generate approximately 676 tons of landfilled waste per year, resulting in fugitive GHG emissions during decomposition of the waste once it is deposited in a landfill (Metz pers. comm.; Steenson pers. comm.).
3.3.2 Thresholds of Significance CEQA Guidelines Section 15064 and relevant portions of Appendix G recommend that a lead agency consider a project’s consistency with relevant adopted plans and discuss any inconsistencies with applicable regional plans, including plans to reduce GHG emissions. Under Appendix G of the CEQA Guidelines, implementing a project would result in a cumulatively considerable contribution to climate change if it would:
•Generate GHG emissions, either directly or indirectly, that may have a significant impact on theenvironment or
•Conflict with an applicable plan, policy, or regulation adopted for the purpose of reducingemissions of GHGs.Public Resources Code Section 21083.3 and CEQA Guidelines Section 15183(e)(2) provide that projects consistent with the development density established by existing zoning, community plan or general plan policies for which an environmental impact report was certified shall not be subject to additional environmental review, except as might be necessary to examine whether there are project-specific significant effects that are peculiar to the project or its site. The project meets the criteria. Accordingly, this analysis evaluates the project’s consistency with the GHG analysis in the General Plan Environmental Impact Report (EIR) to determine whether there are significant project-
Chapter 3: Greenhouse Gases and Climate Change
Air Quality and Greenhouse Gas Technical Report Infinite 101 Project 3-12 June 2023 ICF 104667
specific GHG effects that are peculiar to the project or the project site (City of South San Francisco 2022c). GHG emissions associated with project construction and operations have been quantified. They are presented in this section to provide a comprehensive disclosure of the project’s emissions. As further discussed below, the General Plan EIR determined that GHG impacts from buildout of the General Plan would be less than significant with incorporation of Mitigation Measure AIR-1a, which requires the implementation of construction BMPs.
Compliance with Regulatory Programs In addition to the evaluation of consistency with the City’s General Plan, this analysis also discusses the project’s compliance with regulatory programs designed to reduce GHG emissions from particular activities (e.g., water usage). To the extent that the project’s design features would comply with or exceed the regulations adopted by CARB or other state agencies, the City could rely on this compliance to show that the proposed project would reduce emissions consistent with statewide legislation. This includes an analysis of the project’s consistency with the City’s CAP (City of South San Francisco 2022b). The CAP is not a qualified GHG reduction strategy that can be used for tiering purposes, and thus, it is not used to determine the significance of the project’s emissions. However, this analysis evaluates the project’s consistency with the CAP for informational purposes because the General Plan EIR considered consistency of the General Plan Update with the CAP to determine the significance of impacts.
3.3.3 Impact Analysis
Emissions of Greenhouse Gases Generated during Construction and Operation that May Have a Significant Impact on the Environment
Construction Emissions Construction activities would generate emissions of CO2, CH4, and N2O from mobile and stationary construction equipment, along with employee vehicles and haul trucks. Based on available information provided by the project sponsor, it is expected that construction would occur over eight phases between August 2023 and be completed by March 2026, lasting approximately 31 months.8 The construction modeling outputs and detailed assumptions are included in Attachment A. The estimated construction emissions for the project are summarized by construction year in Table 9. As shown in Table 9, below, it is estimated that construction of the project would generate approximately 3,678 MTCO2e over the entire construction period. Emissions generated during construction of the project would result primarily from the use of diesel-powered construction equipment (e.g., excavators) or the use of on-road vehicles for construction (e.g., haul trucks, workers’ vehicles). Construction emissions would cease once construction of the project is complete and therefore would be considered short term.
8 The analysis assumed construction would begin in August 2023 and end in March 2026 (31 months). After the analysis was conducted, the construction schedule was updated to begin in May 2024 and end in February 2027 (33 months). Over time, construction vehicles and equipment fleets will get cleaner as regulations become more stringent and older, more polluting equipment is replaced by newer, cleaner equipment. In addition, by expanding the construction schedule, emissions will decrease both daily and annually because activities will occur over a longer time frame. Therefore, the analysis is conservative.

Operational Emissions Area, energy, water, and waste emissions were estimated using CalEEMod. Area sources include gas-powered landscaping equipment. Energy sources are typically associated with the combustion of natural gas as well as the use of electricity. Water consumption results in indirect GHG emissions from the conveyance and treatment of water, and waste generation results in fugitive CH4 and N2O emissions from the decomposition of organic matter. Table 10 shows the operational emissions quantified for the project. The operational modeling outputs and detailed assumptions are included in Attachment A. As shown in Table 10, the proposed project would result in approximately 4,274 MTCO2e per year.

Conclusion As shown in Table 9, the project would emit 3,678 MTCO2e of GHG emissions over the entire construction period. Mitigation Measure AIR-1a in the General Plan EIR includes a list of BMPs to reduce dust. The measure would also reduce emissions of GHGs by minimizing idling time and ensuring that all equipment would be properly maintained and tuned. In addition, the City Municipal Code promotes the redirection of recyclable materials generated during construction away from landfills (Chapter 15.60) and requires that all project applicants submit a recycling management plan to estimate the volume of debris generated during construction, along with the estimated amount of
Chapter 3: Greenhouse Gases and Climate Change
Air Quality and Greenhouse Gas Technical Report Infinite 101 Project 3-14 June 2023 ICF 104667
debris that would be sent to the landfill. Furthermore, Section 15.62 of the municipal code requires the City to encourage contractors to make every structure planned for demolition available for deconstruction, salvage, and recovery prior to demolition and recover the maximum feasible amount of salvageable recyclable and reusable material prior to demolition. The General Plan EIR notes that future development, which includes the project, would be required to comply with these requirements of the municipal code and with Mitigation Measure Air-1a. Future development would therefore not generate GHG emissions that could have a significant impact on the environment. The project is consistent with the growth assumptions in the General Plan. With respect to project operations, GHG emissions would total approximately 4,274 MTCO2e per year. The General Plan EIR cites a comprehensive list of policies from the General Plan Update that would help reduce GHG emissions from future development, including the project. The project would be required to comply with the applicable policies from the General Plan Update; thus, GHG emissions may be reduced below the values shown in Table 10. The General Plan EIR also includes a quantitative assessment of citywide GHG emissions from buildout of the General Plan Update. The analysis calculates a service population metric for GHG emissions, which is the emissions of GHGs divided by the total population and number of jobs in the city. The service population metric is then compared to threshold from CARB of 4.0 MTCO2e per service population. As noted in the General Plan EIR, the service population threshold was based on plan-level GHG emissions thresholds recommended in CARB’s scoping plan. It represents the rate of emission reduction necessary for the City to achieve a fair share of statewide GHG reductions and meet the state’s long-term GHG reduction targets. The General Plan EIR concludes that future development in the city would result in emissions that would be less than the threshold of 4.0 MTCO2e—specifically, 3.55 MTCO2e per service population. Thus, future development would not result in GHG emissions that would have a significant impact on the environment. The project’s service population would be approximately 1,548 employees.9 Therefore, the project would result in annual GHG emissions per service population of 2.76 MTCO2e, which is below the General Plan EIR’s estimated GHG emissions per service population of 3.55 MTCO2e.10 Because the project would be consistent with the growth assumptions in the General Plan and within the estimated GHG emissions per service population, the General Plan EIR conclusion also applies to the project.
Consistency with Applicable Plans, Policies, and Regulations Adopted for the Purpose of Reducing GHG Emissions At the local level, the City’s CAP is the plan for reducing GHG emissions. At the state level, AB 32 and SB 32 are the state’s plans for reducing GHG emissions. The project’s consistency with the City CAP, AB 32, and SB 32, including the 2017 Climate Change Scoping Plan, has been assessed to determine the significance of this impact. In addition, the project’s consistency with BAAQMD’s 2017 Clean Air Plan and Plan Bay Area 2050/SB 375 was also evaluated.
Consistency with the City of South San Francisco’s Climate Action Plan The City adopted a CAP in 2022 to reduce community and municipal GHG emissions associated with General Plan buildout. The CAP is a roadmap that outlines a path to achieve carbon neutrality by 2045, reduce emissions 40 percent by 2030 and 80 percent by 2040, equitably mitigate and address the impacts of climate change, and realize the co-benefits of climate mitigation actions that help

create a sustainable community. The CAP features 62 recommended GHG emissions reduction measures within eight sectors of community and municipal operations (i.e., clean energy, built environment, transportation and land use, solid waste, waste and wastewater, carbon sequestration and natural systems, city leadership). The proposed project’s operational emissions are discussed by sector (e.g., mobile sources, energy) and evaluated for CAP consistency.11
Transportation and Land Use Emissions As shown in Table 10, emissions associated with mobile sources would amount to approximately 4,002 MTCO2e per year. The TDM plan includes 13 measures that would be implemented to reduce the number of trips. These include subsidizing transit passes for employees, establishing carpool or vanpool programs, and providing bicycle storage and shower and locker facilities. In addition, the CAP has nine transportation and land use measures. Although many of the measures require action on the City’s part to create policies and incentive programs, the proposed project supports the measures that are considered applicable, as evaluated in Table 11, below.

Federal, state, and local regulatory efforts target three elements of emissions reduction: vehicle fuel efficiency, the carbon content of fuels, and VMT. Most adopted programs and regulations focus on fuel efficiency (e.g., CAFE standards, Pavley standard) and the carbon intensity of transportation fuels (e.g., LCFS). Vehicle electrification is also rapidly becoming part of the state’s approach to reducing mobile-source emissions (e.g., Title 24). The proposed project would not include any features that would conflict with these programs. Rather, it would implement a TDM plan that would reduce the number of trips and VMT. A recent CARB assessment makes clear that the state is “not on track to meet greenhouse gas reductions expected under SB 375.” SB 743 is intended to close the VMT and emissions reduction gap. There is therefore a nexus between SB 743 and state goals to reduce mobile-source GHG emissions. In response to SB 743, OPR released its technical advisory on evaluating transportation impacts under CEQA in December 2018. The advisory indicates that “achieving 15 percent lower per capita (residential) or per employee (office) VMT than existing development is both generally achievable and is supported by evidence that connects this level of reduction to the state’s emissions
Chapter 3: Greenhouse Gases and Climate Change
Air Quality and Greenhouse Gas Technical Report Infinite 101 Project 3-18 June 2023 ICF 104667
goals.” This reduction goal is consistent with recent CARB (2019) analysis, which demonstrates that a 14.3 percent reduction in VMT per capita by 2050 (compared to a 2015–2018 average) would be needed statewide to meet the GHG planning goals. The proposed project would implement a TDM plan that would achieve a gross VMT reduction of 34 percent. This would align with the City’s VMT per capita reduction target of 15 percent below the regional average, which is designed to meet statewide VMT reduction goals. Therefore, it would not conflict with the state’s long-term emissions reduction trajectory for mobile sources.
Area Emissions As shown in Table 10, the proposed project’s emissions associated with area sources would amount to approximately 15 MTCO2e per year. Area sources include gasoline-powered landscaping equipment (e.g., trimmers, mowers). Area-source emissions are based on CalEEMod’s default assumptions, which represent a conservative estimate of equipment usage that corresponds to the square footage of new building space. The CAP does not include measures specific to area-source emissions. In addition, there are no relevant measures in the scoping plan for landscaping equipment. Although an inevitable transition away from fossil-fuel equipment would be needed to achieve carbon neutrality by 2045, the scoping plan did not assume all-electric landscaping equipment in its 2030 reduction analysis. This is consistent with the scoping plan’s overall goal of reducing emissions from fossil-fuel landscaping equipment.
Energy Emissions As shown in Table 10, building energy emissions would not include any emissions from either natural gas or electricity. The proposed project would have all-electric buildings and receive electricity from on-site renewables or PCE, which means there would be no energy-related emissions. PCE uses 100 percent renewable energy to generate electricity. The City CAP has seven energy measures. All of the measures require actions on the City’s part, such as creating policies or incentive programs. The proposed project supports the measures that are considered applicable, as evaluated in Table 12, below.

Solid Waste Emissions As shown in Table 10, the project’s emissions from solid waste would total approximately 151 MTCO2e per year. The CAP has six waste measures, most of which require action on the City’s part to create policies or incentive programs. Two of the measures evaluated in Table 13 are applicable to this project. The features described above (e.g., recycling and organic waste collection) are consistent with the scoping plan’s overall goal of reducing waste emissions and its specific strategy to avoid landfill CH4 emissions by reducing the disposal of landfill waste and organics. In addition, these features would comply with AB 341’s mandatory recycling requirement and support the state’s recycling goal.

Senate Bill 32 (including the 2022 Climate Change Scoping Plan) SB 32 outlines the state’s GHG emissions reduction targets for 2030. Although not legislatively adopted, EO S-03-05 establishes the state’s long-term goal to reduce GHG emissions 80 percent from 1990 levels by 2050. AB 1279 sets a more ambitious state goal of net-zero GHG emissions by 2045 and an 80 percent reduction in anthropogenic emissions from 1990 levels by 2045. In 2008 and 2014, CARB adopted the original scoping plan and first update, respectively, as a framework for achieving AB 32. The scoping plan and first update outline a series of technologically feasible and cost-effective measures to reduce statewide GHG emissions. CARB adopted the 2022 Climate Change Scoping Plan in July 2022 to assess progress toward the statutory 2030 target while laying out a path to achieving carbon neutrality no later than 2045. The 2022 Climate Change Scoping Plan carries forward GHG emissions reduction measures from the 2017 update as well as new measures to help achieve the state’s neutrality goal by 2045 across all sectors of the California economy, including transportation, energy, and industry. GHG emissions generated by proposed project construction activities would be short term and would cease once construction is complete. As discussed above, the project would be subject to Mitigation Measure AIR-1a and the City Municipal Code regulations pertaining to construction GHG emissions, and thus, the project’s emissions from construction would be minimized and would avoid any conflict with statewide emissions reduction goals. The proposed project would also implement sustainability measures, including all-electric buildings, waste diversion measures, and water reduction features that would be consistent with the 2022 Climate Change Scoping Plan and reduce GHG emissions. In addition, OPR’s 2018 Discussion Draft CEQA and Climate Change Advisory notes that a land use development project that “achieves applicable building energy efficiency standards, uses no natural gas or other fossil fuels, and includes Energy Star appliances where available, may be able to demonstrate a less-than-significant greenhouse gas impact associated with project operation.” These measures would assist the state with meeting its GHG reduction goals and would thus not conflict with any adopted statewide plans.
Plan Bay Area 2050/California Senate Bill 375 Plan Bay Area 2050 is consistent with SB 375, which requires MTC to adopt an SCS that outlines policies to reduce per capita GHG emissions from automobiles and light trucks. Environment and transportation are two of four elements discussed in MTC’s Plan Bay Area 2050. Both of these elements comprise a set of strategies that aim to reduce both VMT and emissions. The strategies include a mix of measures that encourage compact growth patterns, alternative transportation, transit, mobility and access, network expansion, and transportation investment.

It is estimated that the project would generate up to 5,808 net daily trips. To reduce VMT and associated emissions, the project would help to improve conditions for walking and biking by providing on-street bicycle racks/lockers, as well as long-term bicycle racks for workers, and orienting the buildings toward the sidewalk, with multiple pedestrian entrances. The proposed project would be an infill development, involving the redevelopment and densification of the site, and would be near local transit lines and routes that provide safe and convenient access for bicyclists and pedestrians, thereby encouraging alternative transportation modes. Overall, the project would incorporate 13 TDM features, which are anticipated to reduce gross VMT by approximately 34 percent. This reduction in gross VMT would make the project consistent with the City’s VMT per capita reduction target of 15 percent below the regional average, which is designed to meet statewide VMT reduction goals. These policies would support alternative transportation within the community, which could help reduce VMT and per capita GHG emissions from passenger vehicles, consistent with Plan Bay Area 2050.
Other State Regulations As discussed above in the analysis of consistency with SB 32, systemic changes will be required at the state level to achieve statewide future GHG reduction goals. Regulations such as the SB 100–mandated 100 percent carbon-free RPS by 2045; implementation of the state’s SLCP Reduction Strategy, including forthcoming regulations for composting and organics diversion; and future updates to the state’s Title 24 standards, including requirements for net-zero energy, will be necessary to attain the magnitude of reductions required by the state’s goals. The proposed project would be required to comply with these regulations in new construction (e.g., in the case of updated Title 24 standards) or be directly affected by the outcomes (e.g., energy consumption would be less carbon intensive with the increasingly stringent RPS). Unlike the scoping plans, which explicitly call for additional emissions reductions from local governments and new projects, none of these state regulations identify specific requirements or commitments for new development beyond what is already required by existing regulations or will be required in forthcoming regulation. Therefore, for the foreseeable future, the proposed project would not conflict with any state-level regulations pertaining to GHGs in the post-2020 era.
Conclusion The proposed project would be consistent with and support all measures that are applicable from the CAP. With respect to mobile sources, the proposed project would achieve the City’s VMT reduction target, which would ensure that the proposed project would be consistent with relevant regulatory programs, such as SB 743, that expressly aim to reduce VMT. In addition, the project would include measures that would be consistent with state regulations to reduce GHG emissions (e.g., SB 100, SLCP Reduction Strategy) as well as applicable policies described in the 2022 Scoping Plan, the 2017 Clean Air Plan, and Plan Bay Area 2050. Consequently, the project would not conflict with achievement of SB 32 reduction goals for 2030 or the RTP/SCS reduction goals for 2035 and 2050. The General Plan EIR determined that buildout of the General Plan would be consistent with applicable plans, policies, and regulations adopted for the purpose of reducing GHG emissions, including the 2022 Scoping Plan, the 2017 Clean Air Plan, and Plan Bay Area 2050. Therefore, the General Plan EIR conclusion also applies to the project.

3.3.4 Cumulative Greenhouse Gas Impacts Climate change is a global problem, and GHG impacts are inherently cumulative. This is because GHGs contribute to the global phenomenon that is climate change, regardless of where they are emitted. Climate change is the result of the individual contributions of countless past, present, and future sources.
