Draft Supplemental Environmental Impact Report Page IV.D-7 Forward Inc. Landfill 2014 Expansion Project state total.e Landfills are a source of carbon dioxide and methane, which are greenhouse gasses (GHGs);however, the carbon dioxide is biogenic and would have been emitted whether the landfill existed or not. As biogenic emissions, carbon dioxide is not included in the GHG emissions, which is consistent with how carbon dioxide is treated in state and federal GHG programs. Methane is a result of the anaerobic conditions in the landfill and is anthropogenic. Regulatory Agencies J The EPA is responsible for implementing a myriad of programs established under the federal CAA, such as establishing and reviewing the NAAQS and judging the adequacy of State Implementation Plans (SIPS). However, EPA has delegated the authority to — implement many of the federal programs to the states while retaining an oversight role to ensure that the programs continue to be implemented. The CARB is responsible for establishing and reviewing California's State standards, compiling the California SIP, securing approval of this plan from EPA, and identifying toxic air contaminants. CARB also regulates mobile emissions sources in California, such as construction equipment, trucks, and automobiles, and oversees the activities of air quality management districts, which are organized at the county and/or regional level. The county/regional air quality management districts are primarily responsible for regulating stationary sources at industrial and commercial facilities within their — jurisdictions and for preparing air quality plans that are required under the federal Clean Air Act and California Clean Air Act. These regional air quality plans are prepared by districts throughout the State and compiled by CARB to form California's SIP. The local air districts also have the responsibility and authority to adopt transportation control and — emission reduction programs for indirect and area-wide emission sources. SJVAPCD is the regional agency with jurisdiction over the area surrounding the proposed project. The SJVAPCD is responsible for bringing the area into compliance and/or maintaining air quality within federal and State air quality standards. This includes the responsibility to monitor ambient air pollutant levels and to develop and - implement attainment strategies to ensure that future emissions are within federal and State standards. SJVAPCD's Guide to Assessing and Mitigating Air Quality Impacts (GAMAQI)is a guidance — document designed to provide lead government agencies, consultants, and project proponents with uniform procedures for assessing air quality impacts and preparing the air quality sections of environmental documents. The Guide recommends thresholds for — use in determining whether projects would have significant adverse environmental impacts, identifies methodologies for predicting project emissions and impacts, and identifies measures that can be used to avoid or reduce air quality impacts. Regulations and Policies As required by the federal Clean Air Act and the California Clean Air Act, air basins or — portions thereof have been classified as either "attainment" or"nonattainment" for each criteria air pollutant, based on whether or not the standards have been achieved. Nonattainment areas are also required to prepare air quality plans that include strategies for achieving attainment. The San Joaquin Valley is in attainment of both the NAAQS and the CAAQS for NO2, SO2, CO, and lead. The San Joaquin Valley is nonattainment 6 California Air Resources Board,California Greenhouse Gas Inventory Plan for 2000-2008,May 2010.
