North County Recycling Center and Sanitary Landfill Permit Revision Project Final Initial Study/Mitigated Negative Declaration · San Joaquin County | May 2025 37 • Endangerment Finding: The current and projected concentrations of the six key well- mixed GHGs (CO2, CH4, N2O, hydrofluorocarbons, perfluorocarbons, and sulfur Hexafluoride) in the atmosphere threaten the public health and welfare of current and future generations. The EPA also found that the combined emissions of these GHGs from new motor vehicles and new motor vehicle engines contribute to the GHG pollution that endangers public health and welfare under Clean Air Act Section 202(a). • Endangerment Finding: The current and projected concentrations of the six key well- mixed GHGs (CO2, CH4, N2O, hydrofluorocarbons, perfluorocarbons, and sulfur Hexafluoride) in the atmosphere threaten the public health and welfare of current and future generations. The EPA also found that the combined emissions of these GHGs from new motor vehicles and new motor vehicle engines contribute to the GHG pollution that endangers public health and welfare under Clean Air Act Section 202(a). In 2016, the EPA established two regulations — the New Source Performance Standards (NSPS) for new landfills and the Emission Guidelines (EG) for existing landfills — aimed at reducing methane emissions from landfill gas. The EG requires the installation of an LFG collection and control system at municipal solid waste (MSW) landfills that exceed a specified design capacity and NMOC emission threshold. State Regulations Assembly Bill (AB) 32, Senate Bill (SB) 32, AB 1279 The State has established the following GHG reduction goals: • AB 32: Reduce GHG emissions to 1990 levels by 2020. • SB 32: Reduce GHG emissions to 40 percent below 1990 levels by 2030. • AB 1279: Achieve carbon neutrality as soon as possible, but no later than 2045 and maintain net negative GHG emissions thereafter; and reduce GHG emissions to 85 percent below 1990 levels by 2045. Landfill Methane Regulation The California Air Resources Board (CARB) adopted the Landfill Methane Regulation in 2010, which requires MSW landfills to reduce methane and other air pollutant emissions through emissions monitoring and capturing fugitive methane emissions. Municipal solid waste (MSW) landfills are regulated under local air district rules that implement the federal requirements of the New Source Performance Standards (NSPS) and EG, 40 Code of Federal Regulations Part 60 Subparts WWW and Cc, for MSW landfills. CARB and 22 air districts, including the San Joaquin Valley Air Pollution Control District (Valley Air District), entered into memoranda of understanding to enable the districts to implement and enforce the Landfill Methane Regulation. The Short-Lived Climate Pollutant (SLCP) Reduction Strategy and SB 1383 Promulgated in 2016, SB 1383 set a statewide target to reduce organic waste disposed of in landfills of 50 percent by 2020 and 75 percent by 2025. In addition, SB 1383 requires recovering at least 20 percent of disposed edible food for human consumption by 2025. As organic waste is a primary substance that generates LFG, diverting organic waste from landfills can reduce LFG emissions. The Short-Lived Climate Pollutant (SLCP) Reduction Strategy, adopted by CARB in 2017, is California’s plan for reducing emissions of high global-warming potential gases with short atmospheric lifetimes. SLCPs include methane, hydrofluorocarbons, and anthropogenic black
