percent, from the state's projected 2020 emissions level of 596 MMT of CO2e under a business - as -usual scenario. The Scoping Plan also breaks down the amount of GHG emissions reductions ARB recommends for each emissions sector of the state's GHG inventory. While ARB has identified a GHG reduction target of 15 percent for local governments themselves, it has not yet determined what amount of GHG emissions reductions it recommends from local government land use decisions. However, the Scoping Plan does state that successful implementation of the plan relies on local governments' land use planning and urban growth decisions because local governments have primary authority to plan, zone, approve, and permit land development to accommodate population growth and the changing needs of their jurisdictions. ARB further acknowledges that decisions on how land is used will have large effects on the GHG emissions that will result from the transportation, housing, industry, forestry, water, agriculture, electricity, and natural gas emission sectors. The measures approved by ARB must be enacted by 2012. As of April 2010, 14 ARB regulations had been approved, including all nine Discrete Early Actions, which will provide a reduction of approximately 78 MMTCO2e in 2020 (almost 50% of the goal). Bay Area Air Quality Management District The Project site falls within the San Francisco Bay Area Air Basin and therefore under the jurisdiction of the Bay Area Air Quality Management District (BAAQMD). BAAQMD provides a guidance document titled, "Assessing the Air Quality Impacts of Projects and Plans" (CEQA Air Quality Guidelines), which provides guidance for consideration by lead agencies, consultants, and other parties evaluating air quality impacts conducted pursuant to the California Environmental Quality Act (CEQA). The document provides guidance on evaluating air quality impacts of development projects and local plans, determining whether an impact is significant, and mitigating significant air quality impacts. The current adopted version of the BAAQMD CEQA Guidelines was published in December 1999. On September 4, 2009, BAAQMD published a new set of proposed CEQA Air Quality Guidelines (Draft Guidelines) for consideration by lead agencies, which propose screening levels, thresholds of significance, and methods of analysis for Greenhouse Gas (GHG) emissions. The thresholds of significance were adopted on June 2, 2010, with an updated version of the Guidelines consistent with these thresholds published in June 2010. This analysis is consistent with the adopted thresholds and the June 2010 guidelines and recommended methodologies. 3 California Air Resource Board. April 22, 2010.
