The EPA’s final findings respond to the 2007 U.S. Supreme Court decision that GHG emissions fit within the Clean Air Act definition of air pollu tants. The findings do not in and of themselves impose any emission reduction requirements but allow the EPA to finalize the GHG standards proposed in 2009 for new light-duty vehicles as part of the joint rulemaking with the Department of Transportation (EPA 2009). The EPA’s endangerment finding covers emissions of six key GHGs—CO2, CH4, N2O, hydrofluorocarbons, perfluorocarbons, and SF6—that have been the subject of scrutiny and intense analysis for decades by scientists in the United States and around the world (the first three are applicable to the Proposed Project). In response to the endangerment finding, the EPA issued the Mandatory Reporting of GHG Rule that requires substantial emitters of GHG emissions (large stationary sources, etc.) to report GHG emissions data. Facilities that emit 25,000 metric tons (MT) or more of CO2 per year are required to submit an annual report. State Laws Current State of California guidance and goals for reductions in GHG emissions are generally embodied in Executive Order S-03-05, Executive Order B-30-15; Assembly Bill (AB) 32; Senate Bill (SB) 32; and SB 375. In addition to the regulations discussed below, the State of California has a number of laws relating to GHG in different sectors, including transportation, renewable energy portfolio, energy efficiency, and water efficiency. Executive Order S-03-05 Executive Order S-03-05, signed June 1, 2005, set the following GHG reduction targets for the state: ▪ 2000 levels by 2010 ▪ 1990 levels by 2020 ▪ 80 percent below 1990 levels by 2050 5 - 104
