1.0 INTRODUCTION

This report documents the results of an Air Quality and Greenhouse Gas (GHG) Emissions Assessment completed for the Aerojet Waste Consolidation Project (Project), which includes the construction of a Consolidation Class II Landfill to accept up to 1,000,000 cubic yards (CYs) of material from the existing Aerojet Landfill in northeast Sacramento County, north of Aerojet Road, south of Highway 50, and west of Prairie City Road, as well as other scattered locations within the access-controlled 8,500-acre Aerojet Sacramento facility. This assessment was prepared using methodologies and assumptions recommended in the rules and regulations of the Sacramento Metropolitan Air Quality Management District (SMAQMD) and County of Sacramento. Regional and local existing conditions are presented, along with pertinent emissions standards and regulations. The purpose of this assessment is to estimate Project-generated criteria air pollutants and GHG emissions attributable to the Project and to determine the level of impact the Project would have on the environment.

1.1 Project Location

The ±190-acre Aerojet Landfill is a closed, inactive permitted landfill on a 214-acre Aerojet Rocketdyne, Inc. (AR)-owned parcel situated within the greater AR access-controlled land holding located approximately 17 miles east of Sacramento. As shown in Figure 1. Aerojet Landfill Location, and Figure 2. Site Location and Haul Route Map, the Aerojet Landfill site is located north of Aerojet Road, south of Highway 50, and west of California Circle in Sacramento County. The site includes a combination of natural, gently rolling terrain, and highly disturbed areas from historic mining activities and the waste management units (WMUs). While the WMUs are mostly at ground level, site elevation ranges from approximately 200 to 280 feet above mean sea level. The linear dredge tailing piles range up to several hundred meters in length. Vegetated areas are interspersed between tailing piles and the WMUs. The area immediately surrounding the Landfill is managed as passive open space. Approximately 0.3 mile north of the landfill on the north side of US Highway 50 is a mixture of industrial, commercial and residential development. The landfill is within the Sacramento County-approved Easton development, a future mixed-use community. The Aerojet property, including the Aerojet Landfill, is surrounded and secured by fencing. Entrance to Aerojet property is controlled through access gates and guard stations. Access to the site must be prearranged and authorized by appropriate Aerojet personnel.

Another primary component of the Proposed Project is the White Rock North Dump (WRND), located within the AR access-controlled land holding and north of the White Rock Road/Grant Line Road intersection in Sacramento County (see Figure 2). The WRND is approximately 2.5 miles south of the Aerojet Landfill and is bound on the north by Old White Rock Road (located within AR’s access-controlled property), on the south by White Rock Road, and on the east and west by undeveloped property. The WRND is an existing 100-acre, inactive pre-regulation dump located on a ±250-acre parcel. This operation occurred prior to the promulgation of current landfill regulations. The WRND has not been formally closed with regulatory agencies since operations were discontinued in the early 1970s. The WRND is characterized by variable topography/tailing piles due to extensive gold dredging that occurred in the late 1930s and early 1940s. The site is dominated by weedy ruderal plants; native oaks and nonnative trees are scattered within the dredge tailings and pits along the northern boundary.

Additionally, the Aerojet Borrow Site, another important component of the Proposed Project, is located within Aerojet’s access-controlled property approximately 1.5 miles south of the Aerojet Landfill and 0.4 mile west of White Rock Road (see Figure 2). Access to the Borrow Site is via a driveway from Faulk Road. The Borrow Site, which has been used historically for other Aerojet project aggregate and soils needs, is highly disturbed and contains several 10- to 20-foot high dredge tailing/soil piles from historic mining activities as well as a leveled/cleared area used for material processing, truck loading and transport operations. The area is mostly devoid of vegetation with occasional ruderal/weedy species on the tailings.

The Aerojet Landfill, WRND, and Borrow Site are linked by paved roads. Site access would be provided via a gate from Old White Rock Road. A perimeter road and other internal roads would provide vehicle access to landfill infrastructure to facilitate landfill construction, and long-term inspection and maintenance. Onsite access roads would generally be 20 feet wide, graded, compacted, and surfaced with gravel, recycled concrete or asphalt.

1.2 Project Description

The Project proposes the following phased improvements:

Phase I Aerojet Waste Consolidation Unit: The Project proposes to construct a Class II Landfill to be known as the Aerojet Waste Consolidation Unit (AWCU) on approximately 50-acres of the existing Aerojet-owned 250-acre WRND parcel. The Project would haul up to 1,000,000 CYs of waste soil that exceeds contamination screening levels and inert construction debris (together referred to as Transfer Material) excavated from both the existing closed, inactive, and permitted Aerojet Landfill and other locations within the access-controlled 8,500-acre Aerojet Sacramento facility to the AWCU for disposal. The precise volume of the Aerojet Landfill Transfer Material is not known; however, prior studies have estimated this volume to be 500,000 CYs; therefore, Aerojet would reserve 500,000 CYs of AWCU capacity for Aerojet Landfill Transfer Material. Aerojet anticipates that additional Transfer Material would be generated from within the Aerojet Sacramento facility. If the excavation and hauling activities from different areas are anticipated to be separated by more than 1 year, the portion of the AWCU filled with that material would be capped. (Construction of the AWCU would include an initial 500,000 CY cell (Phase 1A) followed by construction of additional cells in 100,000 CY increments as needed until all Transfer Material has been placed [Phases 1B through 1F]. Should any portion of cells 1B through 1F not be required, that area would become part of Phase 2.) The Transfer Material would be hauled by trucks utilizing primarily existing paved private roads within the access-controlled Aerojet property. The Aerojet Landfill Clean Closure Plan (CCP) requires disposal of the Transfer Material at a Class II Landfill. Following completion of the transfer activities, the AWCU would be closed and capped consistent with Title 27 requirements. For purposes of this analysis, it is assumed a vapor collection system would be required and installed beneath the AWCU double liner. The AWCU would be capped with a geomembrane-based or “alternative cover” in accordance with Title 27.

Phase 2 White Rock Road North Dump Cap and Closure: Phase 2 of the Project includes the capping and closure of the remainder of the existing former WRND waste cells in accordance with Title 27 requirements (±50 acres within the ±250-acre WRND parcel). Additionally, any portion of the Phase 1B through 1F WMUs not constructed as part of the Phase 1 AWCU (up to an additional 26 acres) could become part of the Phase 2 Cap.

1.2.1 2008 Closure Modification Plan/2015 Clean Closure Plan

In 2008 AR proposed a Closure Modification Plan (CMP) in order to excavate and remove all waste from the Aerojet Landfill. The CMP modified the prior closure plans (Final Closure and Post-Closure Maintenance Plan, WMU Areas 1 and 2 and Final Closure Plan, Aerojet Propulsion Division Class III Landfill WMU Areas 3 and 4) for the landfill as these plans consisted of closure with waste in place. The CMP was updated in 2015 and retitled as the Clean Closure Plan (CCP).

The CCP was submitted to the California Integrated Waste Management Board (CIWMB) and the California Central Valley Regional Water Quality Control Board (RWQCB) for approval, with concurrence by the Local Enforcement Agency (LEA), to change the final closure and post closure maintenance plans for the Aerojet Landfill. CEQA compliance included adoption of the Sacramento County Aerojet Landfill Closure Modification Plan Initial Study/Mitigated Negative Declaration and the follow-on Aerojet Landfill CCP Initial Study Addendum.

The fully approved CCP authorizes the excavation, onsite sorting, stockpiling, processing and offsite hauling and disposal of Aerojet Landfill Transfer Material. The Proposed Project is consistent with the approved CCP with one exception, which includes revisions to the assumed offsite Transfer Material haul route and final disposal location. Specifically, under the Proposed Project the proposed AWCU would be the final disposal location and the haul route would consist of the existing paved private roads within the access-controlled Aerojet property. Compared with the fully approved CCP as analyzed under the Sacramento County Aerojet Landfill Closure Modification Plan Initial Study/Mitigated Negative Declaration and the follow-on Aerojet Landfill CCP Initial Study Addendum, the use of the WRND site as proposed by the Project has the benefit of instigating substantially less haul truck trips equating to a reduction of 4.19 million miles traveled.

The Proposed Project phasing, improvements, and schedule are summarized below.

The WRND is an existing 100-acre, inactive pre-regulation dump on a ±250-acre parcel located north of the White Rock Road/Grant Line Road intersection in Sacramento County. Prior to AR ownership, the County of Sacramento contracted companies to operate a disposal facility on the WRND property. This operation occurred prior to the promulgation of current landfill regulations. The WRND has not been formally closed since ceasing operation in the early 1970s.

Phase 1

The proposed Phase I AWCU would cover up to ±50 acres and be constructed on top of the northeast portion of the existing WRND. Construction of the AWCU would include an initial 500,000 CY cell (Phase 1A) followed by construction of additional cells in 100,000 CY increments as needed until all Transfer


https://2009-165.22


Material has been placed (Phases 1B through 1F). Should any portion of cells 1B through 1F not be required, that area would become part of the Phase 2 WRND Cap Project.

The AWCU would only receive Transfer Material from the Aerojet Landfill (at an estimated volume of 500,000 CYs) and a scattering of other locations within the access-controlled 8,500-acre Aerojet Sacramento facility. The AWCU would be designed in compliance with Title 27 of the California Code of Regulation (CCR Title 27) requirements. This would include a double liner, leachate collection and recovery system, a leak detection system, stormwater management system, and other appropriate environmental controls.

The presence and extent of landfill gas emanating from the existing WRND landfill is unknown. AR is currently conducting a landfill gas investigation to determine if a vapor/gas collection system is required. If required, a vapor/gas collection system/layer would be installed below the proposed AWCU. Installation would include a one- to two-foot layer of rough graded stone. A network of slotted high-density polyethylene (HDPE) piping would be installed within this stone layer. The piping would work as a passive system. If needed, the pipes would be manifolded together to a central location where gas could actively be drawn and managed/treated. The level of gas management/treatment would be based upon concentrations detected in the vapor collection system.

The Proposed Project includes the following two offsite improvements including 1) Haul Route Temporary Access Road and 2) Stormwater Transmission and Outfall Facilities. Specifically, construction of a 0.02-mile (approximately 105-foot-long) temporary access road between the haul route’s existing southern terminus and Old White Rock Road is required to connect the haul route with the WRND property and AWCU. Onsite drainage facilities would collect and convey stormwater from a theoretical 1,000-year 24-hour storm event to the northern boundary of the AWCU. From that point, the proposed drainage system would be constructed as an offsite improvement. Two approximately three-foot-wide and 300-foot-long stormwater drainage ditches would be constructed to convey and discharge stormwater to a low area located between historic dredge piles north of Old White Rock Road and the existing fire break/dirt access road, and southwest of the abandoned portion of Grant Line Road. In addition, drainage ditches would be located along the northeast side of the access roads that link the AWCU with Old White Rock Road. The outfall discharge area is comprised primarily of cobble with high infiltration.

Phase 2

The ±50-acre Phase 2 Cap would completely cover the remaining portions of the WRND historic landfill deposits. Excavation of landfill waste at the surface and near surface (up to five feet below ground surface [bgs]) and consolidation with existing deeper WRND cells, may occur prior to capping to reduce the overall size of the Phase 2 Cap. Additionally, any portion of the Phase 1B through 1F WMUs not constructed as part of the Phase 1 AWCU (up to an additional 26 acres) could become part of the Phase 2 Cap. Beneath the Phase 1 AWCU, the WRND final cover would consist of the AWCU improvements which include a double liner installed on top of the WRND beneath the newly constructed AWCU in addition to the final geosynthetic-based cover of the AWCU.

Schedule

Aerojet anticipates the entire Project lifecycle not to exceed 15 years from the issuance of the solid waste facility permit. The construction of AWCU cell 1A (500,000 CY) is anticipated to take four to six months from start to finish. Aerojet currently anticipates that this first Transfer Material to be transferred would come from the Aerojet Landfill; however, based upon real estate market timing and COVID-19 concerns, Transfer Material from some of the other sites in the 8,500-acre Aerojet Sacramento facility may get transferred ahead of Aerojet Landfill material. Regardless, 500,000 CYs of the 1,000,000 CY AWCU volume would be set aside for the Aerojet Landfill project. Assuming the construction of the AWCU commences in Spring 2021, Transfer Material could be received as soon as Fall 2021. In order to maximize the benefit of the AWCU, Aerojet intends on completely filling the 1,000,000 CY AWCU. Although Aerojet does not know the exact timing of hauling and depositing all the Transfer Material from the Aerojet Landfill and other locations within the access-controlled 8,500-acre Aerojet Sacramento facility to the WRND, Aerojet commits to an AWCU closure within 15 years or by the end of 2035.

Construction and related AWCU filling operations would be completed Monday through Friday from 7:00 a.m. to 6:00 p.m. While most construction and filling activities would conform to this operating schedule, some deviation may be necessary depending on the construction task. For example, liner construction/installation can be temperature sensitive and may require start times earlier than 7:00a.m. Should deviation from the normal 7:00a.m to 6:00p.m. Monday through Friday operating schedule be required, these instances would be coordinated with the County and all site work would be completed in compliance with local ordinance and notification requirements.

The preferred schedule for implementation of the WRND Phase 2 Cap is to begin when 1,000,000 CY of Transfer Material have been placed in the AWCU. At this time, the WRND Phase 2 Cap would be constructed. However, since Aerojet does not know the exact timing of all projects that would generate Transfer Material, Aerojet commits to the completion of Phase 2 within 15 years or by the end of 2035. If, at the time that the Phase 2 project needs to be implemented, AWCU capacity remains, Aerojet may propose to consolidate some of the WRND waste material into the AWCU in order to reduce the footprint of the WRND Phase 2 Cap.

Following the acceptance of 1,000,000 CYs of Transfer Material the entire AWCU would be closed and capped. Although Aerojet does not know the exact timing of hauling and depositing all the Transfer Material from the Aerojet Landfill and other locations within the access-controlled 8,500-acre Aerojet Sacramento facility to the WRND, Aerojet commits to an AWCU closure within 15 years or by the end of 2035. The work involved would not be continuous, and it is estimated that the actual work constructing the WRND and hauling and depositing Transfer Material would occur in fits and starts throughout the 15-year period. The WRND Phase 2 Cap/Cover project would also occur by 2035.

As previously described, the Aerojet Borrow Site is located within Aerojet’s access-controlled property approximately 1.5 miles south of the Aerojet Landfill and 0.4 mile west of White Rock Road. The Borrow Site would be used as a source of material for construction of several components of the AWCU including: the vapor collection layer, the base layer of the liner system, the cap, and onsite roadways. Access to the Borrow Site is via a driveway from Faulk Road. Processing activities at the Borrow Site would include


https://2009-165.22


crushing and screening of aggregate and soils to segregate material fractions for the different AWCU uses (e.g., vapor collection system, leachate collection and recovery system [LCRS] covers and road base). Onsite Project activities would include operation of transportable rock crushing machinery, screening sieves and heavy equipment for material movement, stockpiling and loading. Haul trucks would enter, circulate through the site for loading, and then exit via the Faulk Road driveway.

1 Recyclable metal would be sent to the Schnitzer Steel facility in Rancho Cordova, CA or other appropriate recycling facility. Non-hazardous solid waste would be transported to Kiefer Landfill or other Class III landfill facility. Designated non-hazardous waste materials would be disposed of at Potrero Hills Landfill, Forward Landfill or other Class II Landfill facility. While not expected, should any Class I material be discovered it would be transported to an appropriate facility such as the Chemical Waste Management – Kettleman Hills Landfill. The Kettleman Hills Landfill is located west of I-5 and north of Highway 41 approximately 219 miles south of the project site. Because haul trips to Kettleman Hills Landfill are not anticipated, related mileage is not included in the average trip length range calculation.

2 A trip length of between 7.4 and 62.4 miles one way is assumed. The low end of the range is the average trip length to Schnitzer Steel Recycling (8.6 miles) and Kiefer Landfill (6.1 miles); the high-end range is the average length to Potrero Hills Landfill (67 miles) and Forward Landfill (57.8 miles) as identified in note 1.

3 Assumes 50 acres of clearing and prep and 1-3 truck trips per acre = 50-150 haul trips. 4 A trip length of 2.55 miles is assumed which is the average of the Aerojet Landfill and Aerojet Borrow Site trip lengths. 5 Assumes a soil density of 2.0 tons/CY and average payloads between 23 to 40 tons per tractor, the number of round trips from onsite

landfill to AWCU is estimated as follows: 50 Acres (1M CY Construction) Requires 161,332 CY or 322,664 tons of stone = ~8,076 to 14,028round trips.

6 Assumes soil density of 1.5 tons/CY and average payloads between 23 to 40 tons per tractor load, the number of round trips from Aerojet landfill and other locations within the access-controlled 8,500-acre Aerojet Sacramento facility to AWCU is estimated as follows: 1M CY or 1,500,000 tons of waste material = ~37,500 to 65,217round trips.

7 Assuming a soil density of 1.5 tons/CY and average payloads between 23 to 40 tons per tractor, the number of round trips from the borrow area is estimated as follows: (1M CY Landfill) 200,000 CY or 300,000 tons = 7,500 to 13,043 round trips. These haul trips account for additional material to create drainage features, anchor trenching fill, etc.

Compared with the fully approved CCP as analyzed under the Sacramento County Aerojet Landfill Closure Modification Plan Initial Study/Mitigated Negative Declaration and the follow-on Aerojet Landfill CCP Initial Study Addendum, the use of the WRND site as proposed by the Project has the following benefits:


https://2009-165.22


Substitutes an 8.5-mile roundtrip for a 120-mile roundtrip for trucks hauling material to a Class II landfill, thereby reducing by ninety-seven percent (97%) the vehicle miles traveled – from 4.3 million miles to approximately 113,000 miles, a reduction of 4.19 million miles.

Eliminates approximately 44 truck trips per hour, and approximately 264 truck trips per day, from local public roads and state highways in favor of private roadways entirely within the Aerojet controlled property.

Eliminates emissions from approximately 4.19 million miles of diesel truck hauling.

Eliminates truck traffic departing and returning to the site every 90 seconds, six hours a day, five days a week, on public roads.

Reduces accident risks on public roads by eliminating from public right-of-way all truck trips associated with the transfer of waste material between the two landfills.

Relieves stress on offsite landfills.

As described, compared with the fully approved CCP as analyzed under the Sacramento County Aerojet Landfill Closure Modification Plan Initial Study/Mitigated Negative Declaration and the follow-on Aerojet Landfill CCP Initial Study Addendum, the use of the WRND site as proposed by the Project eliminates emissions from approximately 4.19 million miles of diesel truck hauling. For the purposes of disclosure, the 2017 version of the EMission FACtor model (EMFAC) developed by CARB was employed to calculate the quantity of air pollutant emissions that would be generated by the 4.19 million miles of haul truck travel that would be eliminated under the Proposed Project. EMFAC 2017 is a mathematical model that was developed to calculate emission rates from motor vehicles that operate on highways, freeways, and local roads in California and is commonly used by CARB to project changes in future emissions from on-road mobile sources including cars, trucks, and buses in California. EMFAC 2017 includes the latest data on California’s truck fleets and travel activity. Table 1-4 identifies the quantity of air pollutant emissions that would be generated by 4.19 million miles of haul truck travel.

The approved CCP estimated 148 days of truck hauling, thus daily vehicle miles traveled equates to 28,513.5 miles [4,190,000 ÷ 148 = 28,310.8]. It is noted that Table 2-6 only identifies the quantity of air pollutant emissions that would be generated by 4.19 million miles of haul truck travel, and does not include emissions that would occur from excavating and loading Transfer Material from the Aerojet Landfill as currently allowed under the approved CCP and as analyzed under the previous Sacramento County Aerojet Landfill Closure Modification Plan Initial Study/Mitigated Negative Declaration.

During construction, the Project would implement a variety of Environmental Stewardship Measures (ESMs) designed to avoid short- and long-term effects on the physical and human environment as mandated under the Sacramento County Aerojet Landfill Closure Modification Plan Initial Study/Mitigated Negative Declaration and the follow-on Aerojet Landfill CCP Initial Study Addendum. These measures are considered part of the Project. Project Environmental Stewardship Measures specific to the generation of air pollutant emissions include ESM-12, Implement Measures to Minimize Air Quality Impacts, which requires the Project to implement the several best management practices intended to minimize air quality impacts, specifically the installation of cobble at construction site entrance/exit, suspending grading during high wind events, maintaining adequate moisture in disturbed or stockpiled materials, applying water mist and spray to control fugitive dust emissions, and compacting or using soil stabilizers and/or temporary cover materials to protect disturbed or stockpiled materials. ESM-13, Perform Air Quality Monitoring to Protect Construction Workers, requires the use of aerosol meters and other local air monitoring devices during the placement of Transfer Material in order to ensure emission compliance and worker safety. As part of this Environmental Stewardship Measure, five gas meters with photo ionization detector functions will be utilized during excavation and other remedial efforts to monitor for typical conditions and contaminants of concern that might be encountered. Perimeter air monitoring for visible dust and other contaminants must also be established.

2.0 AIR QUALITY

2.1 Air Quality Setting

Air quality in a region is determined by its topography, meteorology, and existing air pollutant sources. These factors are discussed below, along with the current regulatory structure that applies to the Sacramento Valley Air Basin, which encompasses the Project site, pursuant to the regulatory authority of the Sacramento Metropolitan Air Quality Management District (SMAQMD).

Ambient air quality is commonly characterized by climate conditions, the meteorological influences on air quality, and the quantity and type of pollutants released. The air basin is subject to a combination of topographical and climatic factors that reduce the potential for high levels of regional and local air pollutants. The following section describes the pertinent characteristics of the air basin and provides an overview of the physical conditions affecting pollutant dispersion in the Project area.

2.1.1 Sacramento Valley Air Basin

The California Air Resources Board (CARB) divides the state into air basins that share similar meteorological and topographical features. The Project site is located in the Sacramento Valley Air Basin (SVAB), which is under the jurisdiction of the SMAQMD. The air basin is relatively flat, bordered by mountains to the east, west, and north and by the San Joaquin Valley to the south. Air flows into the SVAB through the Carquinez Strait, moving across the Sacramento Delta, and bringing with it pollutants from the heavily populated San Francisco Bay Area. The climate is characterized by hot, dry summers and cool, rainy winters. Characteristic of SVAB winter weather are periods of dense and persistent low-level fog, which are most prevalent between storm systems. From May to October, the region’s intense heat and sunlight lead to high ozone pollutant concentrations. Summer inversions are strong and frequent but are less troublesome than those that occur in the fall. Autumn inversions, formed by warm air subsiding in a region of high pressure, have accompanying light winds that do not provide adequate dispersion of air pollutants.

Meteorological Influences on Air Quality

Regional flow patterns affect air quality patterns by directing pollutants downwind of sources. Localized meteorological conditions, such as moderate winds, disperse pollutants and reduce pollutant concentrations. However, the mountains surrounding the SVAB can create a barrier to airflow, which can trap air pollutants in the valley when meteorological conditions are right and a temperature inversion exists. The highest frequency of air stagnation occurs in the autumn and early winter when large high-pressure cells lie over the valley. The lack of surface wind during these periods and the reduced vertical air flow caused by less surface heating reduces the influx of outside air and allows air pollutants to become concentrated in a stable volume of air. The surface concentrations of pollutants are highest when these conditions are combined with smoke from agricultural burning or when temperature inversions trap cool air, fog, and pollutants near the ground.

The ozone season (May through October) in the valley is characterized by stagnant morning air or light winds, with the delta sea breeze arriving in the afternoon out of the southwest. Usually the evening breeze


https://2009-165.22


transports the airborne pollutants to the north out of the valley. During about half of the days from July to September, however, a phenomenon called the Schultz Eddy prevents this from occurring. Instead of allowing the prevailing wind patterns to move north and carry the pollutants out of the valley, the Schultz Eddy causes the wind pattern to circle back south. This phenomenon exacerbates the pollution levels in the area and increases the likelihood of violating federal or state standards.

2.1.2 Sources of Regional Air Pollution

Motor vehicle transportation, including automobiles, trucks, transit buses, and other modes of transportation, is the major contributor to regional air pollution. Stationary sources were once important contributors to both regional and local pollution; however, their role has been substantially reduced in recent years by pollution control programs.

2.1.3 Criteria Air Pollutants

Criteria air pollutants are defined as those pollutants for which the federal and state governments have established air quality standards for outdoor or ambient concentrations to protect public health with a determined margin of safety. Ozone (O3), coarse particulate matter (PM10), and fine particulate matter (PM2.5) are generally considered to be regional pollutants because they or their precursors affect air quality on a regional scale. Pollutants such as carbon monoxide (CO), nitrogen dioxide (NO2), and sulfur dioxide (SO2) are considered to be local pollutants because they tend to accumulate in the air locally. PM is also considered a local pollutant. Health effects commonly associated with criteria pollutants are summarized in Table 2-1.

Table 2-1. Criteria Air Pollutants – Summary of Common Sources and Effects

Pollutant Major Manmade Sources Human Health & Welfare Effects CO An odorless, colorless gas formed when carbon in fuel is

not burned completely; a component of motor vehicle exhaust.

Reduces the ability of blood to deliver oxygen to vital tissues, effecting the cardiovascular and nervous system. Impairs vision, causes dizziness, and can lead to unconsciousness or death.

NO2 A reddish-brown gas formed during fuel combustion for motor vehicles, energy utilities and industrial sources.

Respiratory irritant; aggravates lung and heart problems. Precursor to ozone and acid rain. Causes brown discoloration of the atmosphere.

O3 Formed by a chemical reaction between reactive organic gases (ROGs) and nitrous oxides (N2O) in the presence of sunlight. Common sources of these precursor pollutants include motor vehicle exhaust, industrial emissions, solvents, paints and landfills.

Irritates and causes inflammation of the mucous membranes and lung airways; causes wheezing, coughing and pain when inhaling deeply; decreases lung capacity; aggravates lung and heart problems. Damages plants; reduces crop yield.

PM10 & PM2.5

Power plants, steel mills, chemical plants, unpaved roads and parking lots, wood-burning stoves and fireplaces, automobiles and others.

Increased respiratory symptoms, such as irritation of the airways, coughing, or difficulty breathing; aggravated asthma; development of chronic bronchitis; irregular heartbeat; nonfatal heart attacks; and premature death in people with heart or lung disease. Impairs visibility (haze).

SO2 A colorless, nonflammable gas formed when fuel containing sulfur is burned. Examples are refineries, cement manufacturing, and locomotives.

Respiratory irritant. Aggravates lung and heart problems. Can damage crops and natural vegetation. Impairs visibility.

Carbon Monoxide

CO in the urban environment is associated primarily with the incomplete combustion of fossil fuels in motor vehicles. CO combines with hemoglobin in the bloodstream and reduces the amount of oxygen that can be circulated through the body. High CO concentrations can cause headaches, aggravate cardiovascular disease and impair central nervous system functions. CO concentrations can vary greatly over comparatively short distances. Relatively high concentrations of CO are typically found near crowded intersections and along heavy roadways with slow moving traffic. Even under the most severe meteorological and traffic conditions, high concentrations of CO are limited to locations within relatively short distances (i.e., up to 600 feet or 185 meters) of the source. Overall CO emissions are decreasing as a result of the Federal Motor Vehicle Control Program, which has mandated increasingly lower emission levels for vehicles manufactured since 1973. CO levels in the SoCAB are in compliance with the state and federal one- and eight-hour standards.

Nitrogen Oxides

Nitrogen gas comprises about 80 percent of the air and is naturally occurring. At high temperatures and under certain conditions, nitrogen can combine with oxygen to form several different gaseous compounds collectively called nitric oxides (NOx). Motor vehicle emissions are the main source of NOx in urban areas. NOx is very toxic to animals and humans because of its ability to form nitric acid with water in the eyes, lungs, mucus membrane, and skin. In animals, long-term exposure to NOx increases susceptibility to respiratory infections, and lowering resistance to such diseases as pneumonia and influenza. Laboratory studies show that susceptible humans, such as asthmatics, who are exposed to high concentrations can suffer from lung irritation or possible lung damage. Precursors of NOx, such as NO and NO2, attribute to the formation of O3 and PM2.5. Epidemiological studies have also shown associations between NO2 concentrations and daily mortality from respiratory and cardiovascular causes and with hospital admissions for respiratory conditions.

Ozone

O3 is a secondary pollutant, meaning it is not directly emitted. It is formed when volatile organic compounds (VOCs) or ROGs and NOx undergo photochemical reactions that occur only in the presence of sunlight. The primary source of ROG emissions is unburned hydrocarbons in motor vehicle and other internal combustion engine exhaust. NOx forms as a result of the combustion process, most notably due to the operation of motor vehicles. Sunlight and hot weather cause ground-level O3 to form. Ground-level O3 is the primary constituent of smog. Because O3 formation occurs over extended periods of time, both O3 and its precursors are transported by wind and high O3 concentrations can occur in areas well away from sources of its constituent pollutants.

People with lung disease, children, older adults, and people who are active can be affected when O3 levels exceed ambient air quality standards. Numerous scientific studies have linked ground-level O3 exposure to a variety of problems including lung irritation, difficult breathing, permanent lung damage to those with repeated exposure, and respiratory illnesses.


https://2009-165.22


Particulate Matter

PM includes both aerosols and solid particulates of a wide range of sizes and composition. Of concern are those particles smaller than or equal to 10 microns in diameter size (PM10) and small than or equal to 2.5 microns in diameter (PM2.5). Smaller particulates are of greater concern because they can penetrate deeper into the lungs than larger particles. PM10 is generally emitted directly as a result of mechanical processes that crush or grind larger particles or form the resuspension of dust, typically through construction activities and vehicular travel. PM10 generally settles out of the atmosphere rapidly and is not readily transported over large distances. PM2.5 is directly emitted in combustion exhaust and is formed in atmospheric reactions between various gaseous pollutants, including NOx, sulfur oxides (SOx) and VOCs. PM2.5 can remain suspended in the atmosphere for days and/or weeks and can be transported long distances.

The principal health effects of airborne PM are on the respiratory system. Short-term exposure of high PM2.5 and PM10 levels are associated with premature mortality and increased hospital admissions and emergency room visits. Long-term exposure is associated with premature mortality and chronic respiratory disease. According to the U.S. Environmental Protection Agency (USEPA), some people are much more sensitive than others to breathing PM10 and PM2.5. People with influenza, chronic respiratory and cardiovascular diseases, and the elderly may suffer worse illnesses; people with bronchitis can expect aggravated symptoms; and children may experience decline in lung function due to breathing in PM10 and PM2.5. Other groups considered sensitive include smokers and people who cannot breathe well through their noses. Exercising athletes are also considered sensitive because many breathe through their mouths.

2.1.4 Toxic Air Contaminants

In addition to the criteria pollutants discussed above, toxic air contaminants (TACs) are another group of pollutants of concern. TACs are considered either carcinogenic or noncarcinogenic based on the nature of the health effects associated with exposure to the pollutant. For regulatory purposes, carcinogenic TACs are assumed to have no safe threshold below which health impacts would not occur, and cancer risk is expressed as excess cancer cases per one million exposed individuals. Noncarcinogenic TACs differ in that there is generally assumed to be a safe level of exposure below which no negative health impact is believed to occur. These levels are determined on a pollutant-by-pollutant basis.

There are many different types of TACs, with varying degrees of toxicity. Sources of TACs include industrial processes such as petroleum refining and chrome plating operations, commercial operations such as gasoline stations and dry cleaners, and motor vehicle exhaust. Public exposure to TACs can result from emissions from normal operations, as well as from accidental releases of hazardous materials during upset conditions. The health effects of TACs include cancer, birth defects, neurological damage, and death.

Diesel Exhaust

Most recently, CARB identified DPM as a TAC. DPM differs from other TACs in that it is not a single substance but rather a complex mixture of hundreds of substances. Diesel exhaust is a complex mixture of particles and gases produced when an engine burns diesel fuel. DPM is a concern because it causes lung


https://2009-165.22


cancer; many compounds found in diesel exhaust are carcinogenic. DPM includes the particle-phase constituents in diesel exhaust. The chemical composition and particle sizes of DPM vary between different engine types (heavy-duty, light-duty), engine operating conditions (idle, accelerate, decelerate), fuel formulations (high/low sulfur fuel), and the year of the engine (USEPA 2002). Some short-term (acute) effects of diesel exhaust include eye, nose, throat, and lung irritation, and diesel exhaust can cause coughs, headaches, light-headedness, and nausea. DPM poses the greatest health risk among the TACs; due to their extremely small size, these particles can be inhaled and eventually trapped in the bronchial and alveolar regions of the lung.

2.1.5 Ambient Air Quality

Ambient air quality at the Project site can be inferred from ambient air quality measurements conducted at nearby air quality monitoring stations. CARB maintains more than 60 monitoring stations throughout California. O3, PM10 and PM2.5 are the pollutant species most potently affecting the Project region. As described in detail below, the region is designated as a nonattainment area for the federal O3 and PM2.5

standards and is also a nonattainment area for the state standards for O3 and PM10 (CARB 2018). The Folsom air quality monitoring station, located at 50 Natoma Street approximately 2.5 miles north of the Project site, monitors ambient concentrations of O3 and PM2.5. The Sacramento-Branch Center #2 air quality monitoring station, located at 3847 Branch Center Road, approximately 8.3 miles west of the Project site, monitors ambient concentrations of PM10. Ambient emission concentrations will vary due to localized variations in emission sources and climate and should be considered “generally” representative of ambient concentrations in the Project area.

Table 2-2 summarizes the published data concerning O3, PM2.5 and PM10 since 2016 for each year that the monitoring data is provided.

https://2009-165.22


The USEPA and CARB designate air basins or portions of air basins and counties as being in “attainment” or “nonattainment” for each of the criteria pollutants. Areas that do not meet the standards are classified as nonattainment areas. The National Ambient Air Quality Standards (NAAQS) (other than O3, PM10 and PM2.5 and those based on annual averages or arithmetic mean) are not to be exceeded more than once per year. The NAAQS for O3, PM10, and PM2.5 are based on statistical calculations over one- to three-year periods, depending on the pollutant. The California Ambient Air Quality Standards (CAAQS) are not to be exceeded during a three-year period. The attainment status for the Sacramento County portion of the SVAB, which encompasses the Project site, is included in Table 2-3.

Table 2-3. Attainment Status of Criteria Pollutants in the Sacramento County Portion of the SVAB

Pollutant State Designation Federal Designation

O3 Nonattainment Nonattainment

PM10 Nonattainment Attainment

PM2.5 Attainment Nonattainment

CO Attainment Unclassified/Attainment

NO2 Attainment Unclassified/Attainment

SO2 Attainment Unclassified/Attainment

Source: CARB 2018

The determination of whether an area meets the state and federal standards is based on air quality monitoring data. Some areas are unclassified, which means there is insufficient monitoring data for determining attainment or nonattainment. Unclassified areas are typically treated as being in attainment. Because the attainment/nonattainment designation is pollutant-specific, an area may be classified as nonattainment for one pollutant and attainment for another. Similarly, because the state and federal standards differ, an area could be classified as attainment for the federal standards of a pollutant and as nonattainment for the state standards of the same pollutant. The region is designated as a nonattainment area for the federal O3 and PM2.5 standards and is also a nonattainment area for the state standards for O3

and PM10 (CARB 2018).

2.1.6 Sensitive Receptors

Sensitive receptors are defined as facilities or land uses that include members of the population who are particularly sensitive to the effects of air pollutants, such as children, the elderly, and people with illnesses. Examples of these sensitive receptors are residences, schools, hospitals, and daycare centers. CARB has identified the following groups of individuals as the most likely to be affected by air pollution: the elderly over 65, children under 14, athletes, and persons with cardiovascular and chronic respiratory diseases such as asthma, emphysema, and bronchitis.

The nearest sensitive receptors to the Project site are residences located north of the Aerojet Landfill in the City of Folsom, beyond Highway 50. At the nearest, this residential neighborhood is 1,370 feet from


https://2009-165.22


the northern boundary of the Aerojet Landfill. There are also residences to the south of the WRND, the nearest located approximately 6,601 feet distant.

2.2 Regulatory Framework

2.2.1 Federal

Clean Air Act

The Clean Air Act (CAA) of 1970 and the CAA Amendments of 1971 required the USEPA to establish the NAAQS, with states retaining the option to adopt more stringent standards or to include other specific pollutants. On April 2, 2007, the Supreme Court found that carbon dioxide (CO2) is an air pollutant covered by the CAA; however, no NAAQS have been established for CO2.

These standards are the levels of air quality considered safe, with an adequate margin of safety, to protect the public health and welfare. They are designed to protect those “sensitive receptors” most susceptible to further respiratory distress such as asthmatics, the elderly, very young children, people already weakened by other disease or illness, and persons engaged in strenuous work or exercise. Healthy adults can tolerate occasional exposure to air pollutant concentrations considerably above these minimum standards before adverse effects are observed.

The USEPA has classified air basins (or portions thereof) as being in attainment, nonattainment, or unclassified for each criteria air pollutant, based on whether or not the NAAQS have been achieved. If an area is designated unclassified, it is because inadequate air quality data were available as a basis for a nonattainment or attainment designation. Table 2-3 lists the federal attainment status of the Sacramento County portion of the SVAB for the criteria pollutants.

2.2.2 State

California Clean Air Act

The California Clean Air Act (CCAA) allows the state to adopt ambient air quality standards and other regulations provided that they are at least as stringent as federal standards. CARB, a part of the California Environmental Protection Agency, is responsible for the coordination and administration of both federal and state air pollution control programs within California, including setting the CAAQS. CARB also conducts research, compiles emission inventories, develops suggested control measures, and provides oversight of local programs. CARB establishes emissions standards for motor vehicles sold in California, consumer products (such as hairspray, aerosol paints, and barbecue lighter fluid), and various types of commercial equipment. It also sets fuel specifications to further reduce vehicular emissions. CARB also has primary responsibility for the development of California’s State Implementation Plan (SIP), for which it works closely with the federal government and the local air districts.


https://2009-165.22


California State Implementation Plan

The federal CAA (and its subsequent amendments) requires each state to prepare an air quality control plan referred to as the SIP. The SIP is a living document that is periodically modified to reflect the latest emissions inventories, plans, and rules and regulations of air basins as reported by the agencies with jurisdiction over them. The CAA Amendments dictate that states containing areas violating the NAAQS revise their SIPs to include extra control measures to reduce air pollution. The SIP includes strategies and control measures to attain the NAAQS by deadlines established by the CAA. The USEPA has the responsibility to review all SIPs to determine if they conform to the requirements of the CAA.

State law makes CARB the lead agency for all purposes related to the SIP. Local air districts and other agencies prepare SIP elements and submit them to CARB for review and approval. CARB then forwards SIP revisions to the USEPA for approval and publication in the Federal Register. The SMAQMD 2015 Sacramento Regional 8-Hour Ozone Attainment and Reasonable Further Progress Plan (2015), the PM10

Implementation/Maintenance Plan and Re-Designation Request (2010), and PM2.5

Implementation/Maintenance Plan and Re-designation Request for Sacramento PM2.5 Nonattainment Area (2013) are air quality attainment plans and reports that constitute the SIP for the Sacramento County portion of the SVAB. These air quality planning documents present comprehensive strategies to reduce the O3 precursor pollutants (ROG and NOx) as well as PM emissions from stationary, area, mobile, and indirect sources.

2.2.3 Local

Sacramento Metropolitan Air Quality Management District

The SMAQMD is the air pollution control agency for Sacramento County, including the Project site. The agency’s primary responsibility is ensuring that the NAAQS and CAAQS are attained and maintained in the Sacramento County portion of the SVAB. The SMAQMD coordinates the work of government agencies, businesses, and private citizens to achieve and maintain healthy air quality for the Sacramento area. The SMAQMD develops market-based programs to reduce emissions associated with mobile sources, processes permits, ensures compliance with permit conditions and with SMAQMD rules and regulations, and conducts long-term planning related to air quality. The SMAQMD is also responsible for adopting and enforcing rules and regulations concerning air pollutant sources, issuing permits for stationary sources of air pollutants, inspecting stationary sources of air pollutants, responding to citizen complaints, monitoring ambient air quality and meteorological conditions, awarding grants to reduce motor vehicle emissions, and conducting public education campaigns, as well as many other activities.

The following is a list of noteworthy SMAQMD rules that are required of construction activities associated with the Proposed Project:

Rule 402: Nuisance. The purpose of this rule is to limit emissions which cause injury, detriment, nuisance, or annoyance to any considerable number of persons or the public, or which endanger the comfort, repose, health, or safety of any such persons or the public, or which cause or have natural tendency to cause injury or damage to business or property.


https://2009-165.22


Rule 403: Fugitive Dust. The purpose of this rule is to require that reasonable precautions be taken so as not to cause or allow the emissions of fugitive dust from non-combustion sources from being airborne beyond the property line from which the emission originates.

2.3 Air Quality Emissions Impact Assessment

2.3.1 Thresholds of Significance

The impact analysis provided below is based on the following California Environmental Quality Act (CEQA) Guidelines Appendix G thresholds of significance. The Project would result in a significant impact to air quality if it would do any of the following:

1) Conflict with or obstruct implementation of any applicable air quality plan.

2) Result in a cumulatively considerable net increase of any criteria pollutant for which the Project region is nonattainment under an applicable federal or state ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors).

3) Expose sensitive receptors to substantial pollutant concentrations.

4) Result in other emissions (such as those leading to odors adversely affecting a substantial number of people).

Sacramento Metropolitan Air Quality Management Thresholds

The significance criteria established by the applicable air quality management or air pollution control district (SMAQMD) may be relied upon to make the above determinations. According to the SMAQMD, an air quality impact is considered significant if the proposed Project would violate any ambient air quality standard, contribute substantially to an existing or projected air quality violation, or expose sensitive receptors to substantial pollutant concentrations. The SMAQMD has established thresholds of significance for air quality for construction and operational activities of land use development projects such as that proposed, as shown in Table 2-4.

By its very nature, air pollution is largely a cumulative impact. No single project is sufficient in size, by itself, to result in nonattainment of ambient air quality standards. Instead, a project’s individual emissions contribute to existing cumulatively significant adverse air quality impacts. If a project’s individual emissions exceed its identified significance thresholds, the project would be cumulatively considerable. Projects that do not exceed significance thresholds would not be considered cumulative considerable.

2.3.2 Methodology

Air quality impacts were assessed in accordance with methodologies recommended by CARB and the SMAQMD. Where Project-related criteria air pollutant quantification was required, emissions from offroad equipment and ground disturbance were modeled using the California Emissions Estimator Model (CalEEMod), version 2016.3.2. Emissions from worker commute trips were also calculated with CalEEMod. CalEEMod is a statewide land use emissions computer model designed to quantify potential criteria pollutant emissions associated with both construction and operations from a variety of land use projects. Emissions generated from Project haul truck trips are estimated with the use of the 2017 version of the EMission FACtor model (EMFAC). As previously described, EMFAC 2017 is a mathematical model that was developed to calculate emission rates from motor vehicles that operate on highways, freeways, and local roads in California and is commonly used by CARB to project changes in future emissions from on-road mobile sources including cars, trucks, and buses in California. EMFAC 2017 includes the latest data on California’s truck fleets and travel activity. Project air pollutant emissions were calculated using a combination of model defaults for Sacramento County and Project details contained in Tables 1-1, 1-2, and 1-3. The Project is expected to begin construction in the Spring of 2021. Additionally, this analysis assumes the maximum 1,000,000 CY would be hauled.

2.3.3 Impact Analysis

Project Construction-Generated Criteria Air Quality Emissions

Construction Significance Analysis

Emissions associated with Project implementation would be temporary and short-term but have the potential to represent a significant air quality impact. Two basic sources of short-term emissions will be generated through Project implementation: operation of the heavy-duty equipment (i.e., excavators, loaders, crushers, haul trucks) and the creation of fugitive dust during clearing and grading. Construction activities such as excavation and grading operations, construction vehicle traffic, and wind blowing over exposed soils would generate exhaust emissions and fugitive PM emissions that affect local air quality at various times during construction. Effects would be variable depending on the weather, soil conditions, the amount of activity taking place, and the nature of dust control efforts. The dry climate of the area during the summer months creates a high potential for dust generation. Construction activities would be subject to SMAQMD Rule 403, which, as previously described, requires taking reasonable precautions to prevent the emissions of fugitive dust, such as using water or chemicals, where possible, for control of dust during the clearing of land and other construction activities.

Emissions associated with Project offroad equipment, worker commute trips, and ground disturbance were calculated using the CARB-approved CalEEMod computer program, which is designed to model emissions for land use development projects, based on typical construction requirements. Emissions generated from Project haul truck trips are estimated with EMFAC 2017. See Attachment A for more information regarding the construction assumptions, including types of construction equipment used, haul truck mileage and idling rates, and Project duration, used in this analysis. While construction of the AWCU is expected to commence in Spring 2021 and the exact timing of hauling and depositing all the Transfer Material at the WRND is unknown, Aerojet commits to an AWCU closure within 15 years or by the end of 2035. The work involved would not be continuous, and it is estimated that the actual work constructing the WRND and hauling and depositing Transfer Material would occur in fits and starts throughout the 15-year period. However, emissions predictions in this analysis are based on Phase 1 of the Project commencing in the Spring of 2021 and continuing in a single phase spanning 29 months into the end of 2023, and Phase 2 beginning in 2024. This is conservative as while the actual timing of Project implementation would be dictated by several other forces resulting in Project implementation lasting as much as 15 years, CalEEMod and EMFAC incorporates lower emission factors associated with construction equipment and haul trucks in future years due to improved emissions controls and fleet modernization through turnover. Thus, calculating Project emissions to account for Project implementation at the earliest dates provides the highest estimate of daily emissions.

Predicted maximum daily emissions attributable to Project implementation are summarized in Table 2-5. Such emissions are short-term and of temporary duration, lasting only as long as Project implementation activities occur, but would be considered a significant air quality impact if the volume of pollutants generated exceeds the SMAQMD’s thresholds of significance.

Emissions estimates account for the anticipated equipment fleet and number of workers identified in Table 1-1, as well as the amount of material movement, haul truck trips, and haul truck trip lengths identified in Table 1-2.

As shown in Table 2-5, the highest amount of daily emissions would be generated during the installation of the vapor/gas collection system and during the hauling and placement of 1,000,000 CY of Transfer Material. As also shown, the amount of daily emissions would fall below the SMAQMD daily significance threshold for NOx. SMAQMD states that projects generating less than 80 pounds of PM10 and less than 82 pounds of PM2.5 daily while also implementing SMAQMD’s Basic Construction Emission Control Practices, known as Best Management Practices (BMPs) are considered less than significant. The Project would not exceed the SMAQMD significance criterion for NOX, PM10, or PM2.5 with the implementation of mitigation measure MM AQ-1. Mitigation measure MM AQ-1 requires best available control technology (BACT) and BMPs to be implemented.


https://2009-165.22


Mitigation Measures

MM AQ-1 The following practices are considered feasible for controlling fugitive dust from a construction site. Control of fugitive dust is required by District Rule 403 and enforced by SMAQMD staff.

• Water all exposed surfaces two times daily. Exposed surfaces include but are not limited to soil piles, graded areas, unpaved parking areas, staging areas, and access roads.

• Cover or maintain at least 2 feet of free board space on haul trucks transporting soil, sand, or other loose material on the site. Any haul trucks that would be traveling along freeways or major roadways should be covered.

• Use wet power vacuum street sweepers to remove any visible trackout mud or dirt onto adjacent public roads at least once a day. Use of dry power sweeping is prohibited.

• Limit vehicle speeds on unpaved roads to 15 miles per hour.

• All roadways, driveways, sidewalks, and parking lots to be paved should be completed as quickly as possible. In addition, building pads should be laid as soon as possible after grading unless seeding or soil binders are used.

• Minimize idling time either by shutting equipment off when not in use or reducing the time of idling to 5 minutes [required by California Code of Regulations, Title 13, sections 2449(d)(3) and 2485]. Provide clear signage that posts this requirement for workers at the entrances to the site.

• Maintain all construction equipment in proper working condition according to manufacturer’s specifications. The equipment must be checked by a certified mechanic and determine to be running in proper condition before it is operated.

Bolded text equals the highest maximum emissions. Emissions estimates account for the anticipated equipment fleet and number of workers identified in Table 1-1, as well as the amount of material movement, haul truck trips, and haul truck trip lengths identified in Table 1-2.

As shown in Table 2-6, the amount of annual emissions would fall below the SMAQMD annual significance thresholds.

Criteria pollutant emissions generated during Project construction would not result in a cumulatively considerable net increase of any criteria pollutant for which the Project region is nonattainment under an applicable federal or state ambient air quality standard.

Furthermore, as previously described, compared with the fully approved CCP as analyzed under the Sacramento County Aerojet Landfill Closure Modification Plan Initial Study/Mitigated Negative Declaration and the follow-on Aerojet Landfill CCP Initial Study Addendum, the use of the WRND site as proposed by the Project has the benefit of instigating substantially less haul truck trips equating to a reduction of 4.19 million miles traveled. Table 1-4 above identifies the quantity of air pollutant emissions that would be generated by 4.19 million miles of haul truck travel. A comparison of Table 1-4 and Tables 2-5 and 2-6 show that Project NOx and ROG emissions resulting from Project implementation are substantially reduced compared with the NOx and ROG emissions that would be generated by haul truck trips currently allowed under the approved CCP. This reduction in O3 precursor emissions would be a beneficial impact attributable to the Project.

Project Operations Criteria Air Quality Emissions

Operational Significance Analysis

As previously described, it is anticipated the final Closure Plan would require regular maintenance, monitoring and inspection of the AWCU including the following:










These activities would result in long-term operational emissions of criteria air pollutants such as PM10, PM2.5, CO, and SO2 as well as O3 precursors such as ROGs and NOX. Project-generated increases in emissions would be predominantly associated with motor vehicle and equipment use. As previously described, operational air pollutant emissions were based on Project details contained in Table 1-3.

Long-term operational emissions attributable to the Project are identified in Table 2-7 and compared to the operational significance thresholds promulgated by the SMAQMD.

As shown in Table 2-7, the Project’s emissions would not exceed any SMAQMD thresholds for any criteria air pollutants during operation.

As identified in Table 2-3, the Sacramento County portion of the SVAB is listed as a nonattainment area for the federal O3 and PM2.5 standards and is also a nonattainment area for the state standards for O3 and PM10. O3 is a health threat to persons who already suffer from respiratory diseases and can cause severe ear, nose and throat irritation and increases susceptibility to respiratory infections. PM can adversely affect the human respiratory system. As shown in Table 2-7, the Proposed Project would result in increased emissions of PM10 and PM2.5; however, the correlation between a project’s emissions and increases in nonattainment days, or frequency or severity of related illnesses, cannot be accurately quantified. The overall strategy for reducing air pollution and related health effects in the SMAQMD is contained in the SMAQMD 2015 Sacramento Regional 8-Hour Ozone Attainment and Reasonable Further Progress Plan (2015), the PM10 Implementation/Maintenance Plan and Re-Designation Request (2010), and PM2.5

Implementation/Maintenance Plan and Re-designation Request for Sacramento PM2.5 Nonattainment Area (2013). These air quality planning documents present comprehensive strategies to reduce the O3

precursor pollutants (ROG and NOx) as well as PM emissions from stationary, area, mobile, and indirect sources. Each of these air quality planning documents provide control measures that reduce emissions to attain and maintain federal ambient air quality standards such as the application of available cleaner technologies, best management practices, incentive programs, as well as development and implementation of zero and near-zero technologies and control methods. The CEQA thresholds of


https://2009-165.22


significance established by the SMAQMD are designed to meet the objectives of these air quality planning documents and in doing so achieve and maintain attainment status with state and federal standards. As noted above, the Project would increase the emission of certain pollutants, but would not exceed the thresholds of significance established by the SMAQMD for purposes of reducing air pollution and its deleterious health effects.

Project Consistency with Air Quality Planning

As part of its enforcement responsibilities, the USEPA requires each state with nonattainment areas to prepare and submit a SIP that demonstrates the means to attain the federal standards. The SIP must integrate federal, state, and local plan components and regulations to identify specific measures to reduce pollution in nonattainment areas, using a combination of performance standards and market-based programs. Similarly, under state law, the CCAA requires an air quality attainment plan to be prepared for areas designated as nonattainment with regard to the NAAQS and CAAQS. Air quality attainment plans outline emissions limits and control measures to achieve and maintain these standards by the earliest practical date.

As previously mentioned, the Project site is located within the Sacramento County portion of the SVAB, which is under the jurisdiction of the SMAQMD. The SMAQMD is required, pursuant to the CAA, to reduce emissions of criteria pollutants for which the SVAB is in nonattainment. The SMAQMD is required to submit air quality plans and rate-of-progress milestone evaluations in accordance with the federal Clean Air Act. The SMAQMD air quality attainment plans and reports, which include the 2015 Sacramento Regional 8-Hour Ozone Attainment and Reasonable Further Progress Plan (2015), the PM10

Implementation/Maintenance Plan and Re-Designation Request (2010), and PM2.5

Implementation/Maintenance Plan and Re-designation Request for Sacramento PM2.5 Nonattainment Area (2013), present comprehensive strategies to reduce the ozone precursor pollutants (ROG and NOx) as well as particulate matter (PM) emissions from stationary, area, mobile, and indirect sources.

A Project is consistent with regional air quality planning efforts in part if it is consistent with the population and housing assumptions that were used in the development of the SMAQMD air quality plans. The Project would not be contributing to an increase in population or housing growth. Furthermore, as shown in Tables 2-6, 2-7, and 2-8, all Project emissions would fall below SMAQMD significance thresholds.

Furthermore, a comparison of Table 1-4 and Tables 2-5 and 2-6 show that Project NOx and ROG emissions resulting from Project implementation are substantially reduced compared with the NOx and ROG emissions that would be generated by haul truck trips currently allowed under the approved CCP. This reduction in O3 precursor emissions would be a beneficial impact attributable to the Project.

In conclusion, the Project would not conflict with the land use assumptions or exceed the population or job growth projections used by SMAQMD to develop its air quality attainment plans. Project emissions would be emitted below SMAQMD significance thresholds. Lastly, it is noted that the Project would reduce the distance of haul truck travel currently approved and result in a reduction of emissions. The Project would not conflict with SMAQMD’s air quality planning.


https://2009-165.22


Exposure of Sensitive Receptors to Toxic Air Contaminants

As previously described, sensitive receptors are defined as facilities or land uses that include members of the population that are particularly sensitive to the effects of air pollutants, such as children, the elderly, and people with illnesses. Examples of these sensitive receptors are residences, schools, hospitals, and daycare centers. CARB has identified the following groups of individuals as the most likely to be affected by air pollution: the elderly over age 65, children under age 14, athletes, and persons with cardiovascular and chronic respiratory diseases such as asthma, emphysema, and bronchitis. The nearest sensitive receptors to the Project site are residences located north of the Aerojet Landfill in the City of Folsom, beyond Highway 50. At the nearest, this residential neighborhood is 1,370 feet from the northern boundary of the Aerojet Landfill. There are also residences to the south of the WRND, the nearest located approximately 6,601 feet distant.

Project implementation would result in temporary, short-term Project-generated emissions of diesel particulate matter from the exhaust of off-road, heavy-duty diesel equipment for site preparation (e.g., clearing, grading); soil hauling truck traffic; paving; application of architectural coatings; and other miscellaneous activities. For such activity, PM exhaust is the primary TAC of concern. Particulate exhaust emissions from diesel-fueled engines were identified as a TAC by CARB in 1998. The potential cancer risk from the inhalation of PM exhaust outweighs the potential for all other health impacts (i.e., non-cancer chronic risk, short-term acute risk) and health impacts from other TACs. Accordingly, PM exhaust is the focus of this discussion. According to the SMAQMD (2019), when PM10 and PM2.5 emissions generated by a project are less than the mass emission thresholds for PM10 and PM2.5 (see Table 2-4), the project is considered to have a less than significant impact in terms of exposing sensitive receptors to concentrations of air toxics.

Another important consideration is the proximity of nearby sensitive receptors. Studies show that PM exhaust disperses rapidly (e.g., according to CARB (2005) DPM concentrations decrease by 70 percent at 500 feet from the source), and receptors must be in close proximity to emission sources (over a substantial span of time) in order to be exposed to concentrations of concern. The nearest sensitive residential receptors around the Project site are 1,370 feet distant at the nearest, as measured from the northern boundary of the Aerojet Landfill. As previously described, emissions of PM exhaust would be generated from different locations on the AR property, rather than a single location, because different types of Project implementation activities would not occur at the same place at the same time.

Lastly, during Project implementation the Project would implement a variety of ESMs, as previously described, designed to avoid short- and long-term effects on the physical and human environment as mandated under the Sacramento County Aerojet Landfill Closure Modification Plan Initial Study/Mitigated Negative Declaration and the follow-on Aerojet Landfill CCP Initial Study Addendum. These measures are considered part of the Project. Project ESMs specific to the generation of air pollutant emissions include ESM-12, Implement Measures to Minimize Air Quality Impacts, which requires the Project to implement the several best management practices intended to minimize air quality impacts, specifically the installation of cobble at construction site entrance/exit, suspending grading during high wind events, maintaining adequate moisture in disturbed or stockpiled materials, applying water mist and spray to control fugitive dust emissions, and compacting or using soil stabilizers and/or temporary cover materials to protect


https://2009-165.22


disturbed or stockpiled materials. ESM-13, Perform Air Quality Monitoring to Protect Construction Workers, requires the use of aerosol meters and other local air monitoring devices during the placement of Transfer Material in order to ensure emission compliance and worker safety. As part of this ESM, five gas meters with photo ionization detector functions will be utilized during excavation and other remedial efforts to monitor for typical conditions and contaminants of concern that might be encountered. Perimeter air monitoring for visible dust and other contaminants must also be established.

The Project would not expose receptors to substantial concentrations of air toxics

Odors

Typically, odors are regarded as an annoyance rather than a health hazard. However, manifestations of a person’s reaction to foul odors can range from psychological (e.g., irritation, anger, or anxiety) to physiological (e.g., circulatory and respiratory effects, nausea, vomiting, and headache).

With respect to odors, the human nose is the sole sensing device. The ability to detect odors varies considerably among the population and overall is quite subjective. Some individuals have the ability to smell minute quantities of specific substances; others may not have the same sensitivity but may have sensitivities to odors of other substances. In addition, people may have different reactions to the same odor; in fact, an odor that is offensive to one person (e.g., from a fast-food restaurant) may be perfectly acceptable to another. It is also important to note that an unfamiliar odor is more easily detected and is more likely to cause complaints than a familiar one. This is because of the phenomenon known as odor fatigue, in which a person can become desensitized to almost any odor and recognition only occurs with an alteration in the intensity.

Quality and intensity are two properties present in any odor. The quality of an odor indicates the nature of the smell experience. For instance, if a person describes an odor as flowery or sweet, the person is describing the quality of the odor. Intensity refers to the strength of the odor. For example, a person may use the word “strong” to describe the intensity of an odor. Odor intensity depends on the odorant concentration in the air. When an odorous sample is progressively diluted, the odorant concentration decreases. As this occurs, the odor intensity weakens and eventually becomes so low that the detection or recognition of the odor is quite difficult. At some point during dilution, the concentration of the odorant reaches a detection threshold. An odorant concentration below the detection threshold means that the concentration in the air is not detectable by the average human.

Land uses commonly considered to be potential sources of obnoxious odorous emissions include agriculture (farming and livestock), wastewater treatment plants, food processing plants, chemical plants, composting facilities, refineries, landfills, dairies, and fiberglass molding. The Proposed Project includes the development of a landfill in order to 1,000,000 CYs of material from the existing Aerojet Landfill. The effect of the Project would be to relocate an existing landfill currently 1,370 feet from a residential neighborhood at the nearest, to an area (the AWCU) approximately 6,601 feet distant from any residences. Additionally, a unique aspect of the Proposed Project is that a typical landfill “operational period” would not follow construction. Instead, immediately following completion of waste transport from the Aerojet Landfill, the AWCU would be officially closed and capped. Lastly, the Proposed Project would


https://2009-165.22


also be required to comply with SMAQMD Rule 402 to prevent occurrences of public nuisances. Rule 402 prohibits the discharge from any source that causes nuisance, annoyance, or discomfort to a considerable number of persons.

3.0 GREENHOUSE GAS EMISSIONS

3.1 Greenhouse Gas Setting

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 earth’s atmosphere from space. A portion of the radiation is absorbed by the earth’s surface and a smaller portion of this radiation is reflected back toward space. This absorbed radiation is then emitted from the earth as low-frequency infrared radiation. The frequencies at which bodies emit radiation are proportional to temperature. Because the earth has a much lower temperature than the sun, it 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. Without the greenhouse effect, the earth would not be able to support life as we know it.

Prominent GHGs contributing to the greenhouse effect are CO2, methane (CH4), and N2O. Fluorinated gases also make up a small fraction of the GHGs that contribute to climate change. Fluorinated gases include chlorofluorocarbons, hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride, and nitrogen trifluoride; however, it is noted that these gases are not associated with typical land use development. Human-caused emissions of these GHGs in excess of natural ambient concentrations are believed 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 factors together (Intergovernmental Panel on Climate Change [IPCC] 2014).

Table 3-1 describes the primary GHGs attributed to global climate change, including their physical properties, primary sources, and contributions to the greenhouse effect.

Each GHG differs in its ability to absorb heat in the atmosphere based on the lifetime, or persistence, of the gas molecule in the atmosphere. CH4 traps over 25 times more heat per molecule than CO2, and N2O absorbs 298 times more heat per molecule than CO2 (IPCC 2014). Often, estimates of GHG emissions are presented in carbon dioxide equivalents (CO2e), which weight each gas by its global warming potential. Expressing GHG emissions in CO2e takes the contribution of all GHG emissions to the greenhouse effect and converts them to a single unit equivalent to the effect that would occur if only CO2 were being emitted.

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 pollutants with localized air quality effects have relatively short atmospheric lifetimes (about one day), GHGs have long atmospheric lifetimes (one to several thousand years). GHGs persist in the atmosphere for long enough time periods to be dispersed


https://2009-165.22


around the globe. Although the exact lifetime of any particular GHG molecule is dependent on multiple variables and cannot be pinpointed, it is understood that more CO2 is emitted into the atmosphere than is sequestered by ocean uptake, vegetation, or other forms. Of the total annual human-caused CO2

emissions, approximately 55 percent is sequestered through ocean and land uptakes every year, averaged over the last 50 years, whereas the remaining 45 percent of human-caused CO2 emissions remains stored in the atmosphere (IPCC 2013).

Table 3-1. Greenhouse Gases

Greenhouse Gas Description

CO2 Carbon dioxide is a colorless, odorless gas. CO2 is emitted in a number of ways, both naturally and through human activities. The largest source of CO2 emissions globally is the combustion of fossil fuels such as coal, oil, and gas in power plants, automobiles, industrial facilities, and other sources. A number of specialized industrial production processes and product uses such as mineral production, metal production, and the use of petroleum-based products can also lead to CO2 emissions. The atmospheric lifetime of CO2 is variable because it is so readily exchanged in the atmosphere.1

CH4 Methane is a colorless, odorless gas and is the major component of natural gas, about 87 percent by volume. It is also formed and released to the atmosphere by biological processes occurring in anaerobic environments. Methane is emitted from a variety of both human-related and natural sources. Human-related sources include fossil fuel production, animal husbandry (intestinal fermentation in livestock and manure management), rice cultivation, biomass burning, and waste management. These activities release significant quantities of CH4 to the atmosphere. Natural sources of CH4 include wetlands, gas hydrates, permafrost, termites, oceans, freshwater bodies, non-wetland soils, and other sources such as wildfires. The atmospheric lifetime of CH4 is about12 years.2

N2O Nitrous oxide is a clear, colorless gas with a slightly sweet odor. Nitrous oxide is produced by both natural and human-related sources. Primary human-related sources of N2O are agricultural soil management, animal manure management, sewage treatment, mobile and stationary combustion of fossil fuels, adipic acid production, and nitric acid production. N2O is also produced naturally from a wide variety of biological sources in soil and water, particularly microbial action in wet tropical forests. The atmospheric lifetime of N2O is approximately 120 years.3

The quantity of GHGs that it takes to ultimately result in climate change is not precisely known; it is sufficient to say the quantity is enormous, and no single project alone would measurably contribute to a noticeable incremental change in the global average temperature or to global, local, or microclimates. From the standpoint of CEQA, GHG impacts to global climate change are inherently cumulative.

3.1.1 Sources of Greenhouse Gas Emissions

In 2019, CARB released the 2019 edition of the California GHG inventory covering calendar year 2017 emissions. In 2017, California emitted 424.1 million gross metric tons of CO2e including from imported electricity. Combustion of fossil fuel in the transportation sector was the single largest source of California’s GHG emissions in 2017, accounting for approximately 41 percent of total GHG emissions in the state. This sector was followed by the industrial sector (24 percent) and the electric power sector including both in- and out-of-state sources (15 percent) (CARB 2019b). Emissions of CO2 are by-products of fossil fuel combustion. CH4, a highly potent GHG, primarily results from off-gassing (the release of chemicals from nonmetallic substances under ambient or greater pressure conditions) and is largely associated with agricultural practices and landfills. N2O is also largely attributable to agricultural practices

and soil management. CO2 sinks, or reservoirs, include vegetation and the ocean, which absorb CO2

through sequestration and dissolution (CO2 dissolving into the water), respectively, two of the most common processes for removing CO2 from the atmosphere.

3.2 Regulatory Framework

3.2.1 State

Executive Order S-3-05

Executive Order (EO) S-3-05, signed by Governor Arnold Schwarzenegger in 2005, proclaims that California is vulnerable to the impacts of climate change. It declares that increased temperatures could reduce the Sierra Nevada snowpack, further exacerbate California’s air quality problems, and potentially cause a rise in sea levels. To combat those concerns, the EO established total GHG emission targets for the state. Specifically, emissions are to be reduced to the 2000 level by 2010, the 1990 level by 2020, and to 80 percent below the 1990 level by 2050.

While dated, this EO remains relevant because a more recent California Appellate Court decision, Cleveland National Forest Foundation v. San Diego Association of Governments (November 24, 2014) 231 Cal.App.4th 1056, examined whether it should be viewed as having the equivalent force of a legislative mandate for specific emissions reductions. While the California Supreme Court ruled that the San Diego Association of Governments did not abuse its discretion by declining to adopt the 2050 goal as a measure of significance in light of the fact that the EO does not specify any plan or implementation measures to achieve its goal, the decision also recognized that the goal of a 40 percent reduction in 1990 GHG levels by 2030 is “widely acknowledged” as a “necessary interim target to ensure that California meets its longer-range goal of reducing GHG emissions 80 percent below 1990 levels by the year 2050.

Assembly Bill 32 Climate Change Scoping Plan and Updates

In 2006, the California legislature passed Assembly Bill (AB) 32 (Health and Safety Code § 38500 et seq., or AB 32), also known as the Global Warming Solutions Act. AB 32 requires CARB to design and implement feasible and cost-effective emission limits, regulations, and other measures, such that statewide GHG emissions are reduced to 1990 levels by 2020 (representing a 25 percent reduction in emissions). AB 32 anticipates that the GHG reduction goals will be met, in part, through local government actions. CARB has identified a GHG reduction target of 15 percent from current levels for local governments and notes that successful implementation relies on local governments’ land use planning and urban growth decisions.

Pursuant to AB 32, CARB adopted a Scoping Plan in December 2008, which was re-approved by CARB on August 24, 2011, that outlines measures to meet the 2020 GHG reduction goals. To meet these goals, California must reduce its GHG emissions by 30 percent below projected 2020 business-as-usual emissions levels or about 15 percent from today’s levels. The Scoping Plan recommends measures for further study and possible state implementation, such as new fuel regulations. It estimates that a reduction of 174 million metric tons of CO2e (about 191 million U.S. tons) from the transportation, energy,


https://2009-165.22


agriculture, and forestry sectors and other sources could be achieved should the State implement all of the measures in the Scoping Plan.

The Scoping Plan is required by AB 32 to be updated at least every five years. The first update to the AB 32 Scoping Plan was approved on May 22, 2014 by CARB. The 2017 Scoping Plan Update was adopted on December 14, 2017. The Scoping Plan Update addresses the 2030 target established by SB 32 as discussed below and establishes a proposed framework of action for California to meet a 40 percent reduction in GHG emissions by 2030 compared to 1990 levels. The key programs that the Scoping Plan Update builds on include: increasing the use of renewable energy in the state, the Cap-and-Trade Regulation, the Low Carbon Fuel Standard, and reduction of methane emissions from agricultural and other wastes.

Executive Order B-30-15

On April 20, 2015 Governor Edmund (Jerry) Brown, Jr., signed EO B-30-15 to establish a California GHG reduction target of 40 percent below 1990 levels by 2030. The Governor’s EO aligns California’s GHG reduction targets with those of leading international governments such as the 28-nation European Union, which adopted the same target in October 2014. California is on track to meet or exceed the target of reducing GHG emissions to 1990 levels by 2020, as established in the California Global Warming Solutions Act of 2006 (AB 32, discussed above). California’s new emission reduction target of 40 percent below 1990 levels by 2030 will make it possible to reach the ultimate goal of reducing emissions 80 percent below 1990 levels by 2050. This is in line with the scientifically established levels needed in the U.S. to limit global warming below 2˚C, the warming threshold at which major climate disruptions are projected, such as super droughts and rising sea levels.

Senate Bill 32 and Assembly Bill 197 of 2016

In August 2016, Governor Brown signed SB 32 and AB 197, which serve to extend California’s GHG reduction programs beyond 2020. SB 32 amended the Health and Safety Code to include § 38566, which contains language to authorize CARB to achieve a statewide GHG emission reduction of at least 40 percent below 1990 levels by no later than December 31, 2030. SB 32 codified the targets established by EO B-30-15 for 2030, which set the next interim step in the State’s continuing efforts to pursue the long-term target expressed in EOs S-3-05 and B-30-15 of 80 percent below 1990 emissions levels by 2050.

Senate Bill X1-2 of 2011, Senate Bill 350 of 2015, and Senate Bill 100 of 2018

SB X1-2 of 2011 requires all California utilities to generate 33 percent of their electricity from renewables by 2020. SB X1-2 sets a three-stage compliance period requiring all California utilities, including independently owned utilities, energy service providers, and community choice aggregators, to generate 20 percent of their electricity from renewables by December 31, 2013; 25 percent by December 31, 2016; and 33 percent by December 31, 2020. SB X1-2 also requires the renewable electricity standard to be met increasingly with renewable energy that is supplied to the California grid from sources within, or directly proximate to, California.


https://2009-165.22


In October 2015, SB 350 was signed by Governor Brown, which requires retail sellers and publicly owned utilities to procure 50 percent of their electricity from renewable resources by 2030. In 2018, SB 100 was signed by Governor Brown, codifying a goal of 60 percent renewable procurement by 2030 and 100 percent by 2045 Renewables Portfolio Standard.

3.2.2 Local

County of Sacramento Climate Action Planning

In October of 2011 Sacramento County approved the Climate Action Plan Strategy and Framework document (CAP), which is the first phase of developing a community-level Climate Action Plan. The CAP provides a framework and overall policy strategy for reducing GHG emissions and managing resources in order to comply with AB 32. It also highlights actions already taken to become more efficient, and targets future mitigation and adaptation strategies. The CAP contains policies/goals related to agriculture, energy, transportation/land use, waste, and water.

As part of the CAP, Sacramento County prepared a GHG emissions inventory and based on this inventory, developed GHG significance thresholds for land use development projects. Separate thresholds have been included for the Energy sector and Transportation/Land Use sector, the two most potent sources of GHG emissions. The purpose of this division is to provide additional information about the source of emissions.

Publication of a “Phase II” CAP is anticipated to occur within five years of the adoption of the 2030 Sacramento County General Plan (the General Plan was adopted in November 2011). This second phase CAP is intended to flesh out the strategies involved in the strategy and framework CAP, and will include economic analysis, intensive vetting with all internal departments, community outreach/information sharing, timelines, and detailed performance measures.

Sacramento Metropolitan Air Quality Management District

The SMAQMD has primary responsibility for developing and implementing rules and regulations to maintain the national ambient air quality standards and attain the California ambient air quality standards, permitting new or modified sources, developing air quality management plans, and adopting and enforcing air pollution regulations for all projects in the SVAB. The AB 32 Scoping Plan does not specify an explicit role for local air districts with respect to implementing AB 32, but it does state that CARB will work actively with air districts in coordinating emissions reporting, encouraging and coordinating GHG reductions, and providing technical assistance in quantifying reductions. The ability of air districts to control emissions (both criteria pollutants and GHGs) is provided primarily through permitting, but also via their role as a CEQA lead or commenting agency, the establishment of CEQA thresholds, and the development of analytical requirements for CEQA documents.

The SMAQMD has recommended an approach for assessing a proposed development’s GHG emissions. Specifically, SMAQMD recommends a comparison of a project’s annual construction GHG emissions to a significance threshold of 1,100 metric tons per year. Similarly, SMAQMD recommends a comparison of a project’s annual operational GHG emissions to a significance threshold of 1,100 metric tons per year. If a


https://2009-165.22


threshold is exceeded, then the project may have a cumulatively considerable contribution to a significant cumulative environmental impact, and all feasible mitigation is required.

3.3 Greenhouse Gas Emissions Impact Assessment

3.3.1 Thresholds of Significance

The impact analysis provided below is based on the following CEQA Guidelines Appendix G thresholds of significance. The Project would result in a significant impact to greenhouse gas emissions if it would:

1) Generate GHG emissions, either directly or indirectly, that may have a significant impact on the environment.

2) Conflict with any applicable plan, policy, or regulation of an agency adopted for the purpose of reducing the emissions of greenhouse gases or

The Appendix G thresholds for GHG’s do not prescribe specific methodologies for performing an assessment, do not establish specific thresholds of significance, and do not mandate specific mitigation measures. Rather, the CEQA Guidelines emphasize the lead agency’s discretion to determine the appropriate methodologies and thresholds of significance consistent with the manner in which other impact areas are handled in CEQA. With respect to GHG emissions, the CEQA Guidelines § 15064.4(a) states that lead agencies “shall make a good-faith effort, based to the extent possible on scientific and factual data, to describe, calculate or estimate” GHG emissions resulting from a project. The CEQA Guidelines note that an agency has the discretion to either quantify a project’s GHG emissions or rely on a “qualitative analysis or other performance-based standards.” (14 California Code of Regulations [CCR] 15064.4(b)). A lead agency may use a “model or methodology” to estimate GHG emissions and has the discretion to select the model or methodology it considers “most appropriate to enable decision makers to intelligently take into account the project’s incremental contribution to climate change.” (14 CCR 15064.4(c)). Section 15064.4(b) provides that the lead agency should consider the following when determining the significance of impacts from GHG emissions on the environment:

1. The extent a project may increase or reduce GHG emissions as compared to the existing environmental setting.

2. Whether the project emissions exceed a threshold of significance that the lead agency determines applies to the project.

3. The extent to which the project complies with regulations or requirements adopted to implement a statewide, regional, or local plan for the reduction or mitigation of GHG emissions (14 CCR 15064.4(b)).

In addition, Section 15064.7(c) of the CEQA Guidelines specifies that “[w]hen adopting or using thresholds of significance, a lead agency may consider thresholds of significance previously adopted or recommended by other public agencies, or recommended by experts, provided the decision of the lead agency to adopt such thresholds is supported by substantial evidence” (14 CCR 15064.7(c)). The CEQA


https://2009-165.22


Guidelines also clarify that the effects of GHG emissions are cumulative and should be analyzed in the context of CEQA’s requirements for cumulative impact analysis (see CEQA Guidelines § 15130(f)). As a note, the CEQA Guidelines were amended in response to SB 97. In particular, the CEQA Guidelines were amended to specify that compliance with a GHG emissions reduction plan renders a cumulative impact insignificant.

Per CEQA Guidelines § 15064(h)(3), a project’s incremental contribution to a cumulative impact can be found not cumulatively considerable if the project would comply with an approved plan or mitigation program that provides specific requirements that would avoid or substantially lessen the cumulative problem within the geographic area of the project. To qualify, such plans or programs must be specified in law or adopted by the public agency with jurisdiction over the affected resources through a public review process to implement, interpret, or make specific the law enforced or administered by the public agency. Examples of such programs include a “water quality control plan, air quality attainment or maintenance plan, integrated waste management plan, habitat conservation plan, natural community conservation plans [and] plans or regulations for the reduction of greenhouse gas emissions.” Put another way, CEQA Guidelines § 15064(h)(3) allows a lead agency to make a finding of less than significant for GHG emissions if a project complies with adopted programs, plans, policies and/or other regulatory strategies to reduce GHG emissions.

The significance of the Project’s GHG emissions is evaluated consistent with CEQA Guidelines § 15064.4(b)(2) by considering whether the Project complies with applicable plans, policies, regulations and requirements adopted to implement a statewide, regional, or local plan for the reduction or mitigation of GHG emissions. Specifically, the Project will first be compared to the SMAQMD thresholds of 1,100 metric tons per year during Project construction and 1,100 metric tons per year during Project operations. Secondly, the Project will also be assessed for consistency with the County of Sacramento CAP.

3.3.2 Methodology

GHG emissions-related impacts were assessed in accordance with methodologies recommended by CARB and the SMAQMD. Where Project-related GHG emission quantification was required, emissions from offroad equipment and ground disturbance were modeled using CalEEMod, version 2016.3.2. Emissions from worker commute trips were also calculated with CalEEMod. CalEEMod is a statewide land use emissions computer model designed to quantify potential criteria pollutant emissions associated with both construction and operations from a variety of land use projects. Emissions generated from Project haul truck trips are estimated with the use of EMFAC 2017. As previously described, EMFAC 2017 is a mathematical model that was developed to calculate emission rates from motor vehicles that operate on highways, freeways, and local roads in California and is commonly used by CARB to project changes in future emissions from on-road mobile sources including cars, trucks, and buses in California. EMFAC 2017 includes the latest data on California’s truck fleets and travel activity. Project GHG emissions were calculated using a combination of model defaults for Sacramento County and Project details contained in Tables 1-1, 1-2, and 1-3. The Project is expected to begin construction in the Spring of 2021. Additionally, this analysis assumes the maximum 1,000,000 CY would be hauled.

3.3.3 Impact Analysis

Generation of GHG Emissions

Construction Significance Analysis

Construction-related activities that would generate GHG emissions include worker commute trips and the operation of the heavy-duty equipment (i.e., excavators, loaders, crushers, haul trucks). GHG emissions associated with Project offroad equipment and worker commute trips were calculated using the CARB-approved CalEEMod computer program, which is designed to model emissions for land use development projects, based on typical construction requirements. Emissions generated from Project haul truck trips are estimated with EMFAC 2017. See Attachment A for more information regarding the construction assumptions, including construction equipment and duration, used in this analysis. While construction of the AWCU is expected to commence in Spring 2021 and the exact timing of hauling and depositing all the Transfer Material at the WRND is unknown, Aerojet commits to an AWCU closure within 15 years or by the end of 2035. The work involved would not be continuous, and it is estimated that the actual work constructing the WRND and hauling and depositing Transfer Material would occur in fits and starts throughout the 15-year period. However, emissions predictions in this analysis are based on Phase 1 of the Project commencing in the Spring of 2021 and continuing in a single phase spanning 29 months into the end of 2023, and Phase 2 beginning in 2024. This is conservative as while the actual timing of Project implementation would be dictated by several other forces resulting in Project implementation lasting as much as 15 years, CalEEMod and EMFAC incorporates lower emission factors associated with construction equipment and haul trucks in future years due to improved emissions controls and fleet modernization through turnover. Thus, calculating Project emissions to account for Project implementation at the earliest dates provides the highest estimate of emissions.

Predicted maximum annual GHG emissions attributable to Project implementation are summarized in Table 3-2. Such emissions are short-term and of temporary duration, lasting only as long as Project implementation activities occur, but would be considered a significant air quality impact if the volume of GHG emissions generated exceeds the SMAQMD’s thresholds of significance.

Source: CalEEMod version 2016.3.2; EMFAC 2017. Refer to Attachment A for Model Data Outputs. Notes: Emissions estimates account for the anticipated equipment fleet and number of workers identified in Table 1-1, as well as the

amount of material movement, haul truck trips, and haul truck trip lengths identified in Table 1-2.

As shown in Table 3-2, the highest amount of annual GHG emissions would be generated during a year of hauling and placement of Transfer Material, Phase 1 cap and cover implementation, and the site fencing installation. The amount of annual GHG emissions are predicted to fall below the SMAQMD annual significance threshold.

Furthermore, as previously described, compared with the fully approved CCP as analyzed under the Sacramento County Aerojet Landfill Closure Modification Plan Initial Study/Mitigated Negative Declaration and the follow-on Aerojet Landfill CCP Initial Study Addendum, the use of the WRND site as proposed by the Project has the benefit of instigating substantially less haul truck trips equating to a reduction of 4.19 million miles traveled. Table 1-4 above identifies the quantity of GHG emissions that would be generated by 4.19 million miles of haul truck travel. A comparison of Table 1-4 and Table 3-2 shows that Project CO2e emissions resulting from Project implementation are substantially reduced compared with the CO2e emissions that would be generated by haul truck trips currently allowed under the approved CCP. This reduction in GHG emissions would be a beneficial impact attributable to the Project.

Operational Significance Analysis

As previously described, it is anticipated the final Closure Plan would require regular maintenance, monitoring and inspection of the AWCU including the following:





https://2009-165.22








These activities would result in long-term operational GHG emissions. Project-generated increases in emissions would be predominantly associated with motor vehicle and equipment use. As previously described, operational GHG emissions were based on Project details contained in Table 1-3.

Long-term operational GHG emissions attributable to the Project are identified in Table 3-3 and compared to the operational GHG significance thresholds promulgated by the SMAQMD.

As shown in Table 3-3, the Project’s emissions would not exceed any SMAQMD thresholds for GHG emissions during operation.

Conflict with any Applicable Plan, Policy, or Regulation of an Agency Adopted for the Purpose of Reducing the Emissions of Greenhouse Gases

As previously described, the Sacramento County CAP provides a framework and overall policy strategy for reducing GHG emissions and managing resources in order to comply with statewide GHG reduction goals. It also highlights actions already taken to become more efficient, and targets future mitigation and adaptation strategies. The CAP contains policies/goals related to agriculture, energy, transportation/land use, waste, and water. As part of the CAP, Sacramento County prepared a GHG emissions inventory and based on this inventory, developed GHG significance thresholds for land use development projects. Separate thresholds have been included for the Energy sector and Transportation/Land Use sector, the two most potent sources of GHG emissions. The purpose of this division is to provide additional information about the source of emissions.

The County CAP does not promulgate specific thresholds for construction-type projects such as that proposed by the Aerojet Waste Consolidation Project. However, although there would be emissions


https://2009-165.22


associated with the Project (see Table 3-2), Project GHG emissions resulting from construction are substantially reduced compared with the GHG emissions that would be generated by haul truck trips currently allowed under the approved CCP. This reduction would be a beneficial impact attributable to the Project. Thus, since the primary intent of the County CAP is to reduce GHG emissions in the County, the Project is consistent with the intent of the CAP and would in no way conflict with it.

1 Daily Idling ‐ Calculations assume 15 minutes of idling per daily haul truck trip. The amount of total haul trips in Table 1‐2 for Phase 1 Cap/Cover of the Emissions Assessment (26,086) ÷ the amount of days required to complete the activity (35). [26,086 total trips ÷ 35 days = 745.3. Rounded to 746 trips x 15 minutes = 11,190 minutes of idling daily.

The amount of days required to complete this activity is based on the Production Rate identified in Table 1‐1 for Phase 1 Cap/Cover of the Emissions Assessment (1.5 acres of cover per day). 1.5 acres of cover installation per day at 53‐acre WRND = 35 days.
