San Francisco Bay Area Air Quality Management Plans
This page contains information regarding
recent and historical SIP activity related to the San Francisco Bay
Area. Below you will find links to the 2012 PM2.5 emission inventory SIP submittal, the 2001 and 1999 Ozone Attainment Plans, and associated documents such as letters submitting the plans to ARB
and the U.S. Environmental Protection Agency, resolutions, staff
reports, emissions inventory, and public hearing notices.
Previous SIP submittals are available in hardcopy from the Air Quality Transportation and Planning Branch at (916)322-0285 and the Bay Area Air Quality Management District at http://www.baaqmd.gov and (415) 771-6000.
2012 San Francisco Bay Area PM2.5 Emission Inventory
At a public meeting held on December 6, 2012, the Air Resources Board (ARB) approved the San Francisco Bay Area PM2.5 Emission Inventory submittal to the State Implementation Plan. The PM2.5 Emission Inventory was submitted to the U.S. EPA on January 14, 2013. The information on this page provides links to ARB and District documentation, as well as U.S. EPA actions.

2001 Ozone Plan
On November 1, 2001, the Board approved the San Francisco Bay Area 2001 Ozone Attainment Plan for the 1-Hour National Ozone Standard (2001 Plan) as a revision to the State Implementation Plan (SIP). This was a continuation of the initial hearing of this item on July 26, 2001. The Bay Area Air Quality Management District (District) and its co-lead agencies, the Metropolitan Transportation Commission (MTC) and the Association of Bay Area Governments (ABAG) adopted the 2001 Plan on October 26, 2001.
The District prepared
the 2001 Plan because the Bay Area failed to attain the federal
ozone standard by its 2000 deadline. As a result, the U.S.
Environmental Protection Agency (U.S. EPA) disapproved
the Bay Area's 1999 Plan and required a new plan with an updated
volatile organic compounds (VOC) and nitrogen
oxides (NOx) emissions inventory, new transportation conformity
budgets, and that shows attainment of the federal
ozone standard by 2006.
The 2001 Plan contains a control strategy with seven new stationary source measures, five new transportation control measures (TCMs), and eleven further-study measures. In the 2001 Plan, the District also commits to strengthen the Smog Check program by requesting the State Bureau of Automotive Repair to implement two VOC-reducing program elements. The new measures and on-going programs will provide 271 tons per day of combined VOC and NOx emission reductions between 2000 and 2006. The 2001 Plan also includes a new attainment assessment based on currently available data for the Bay Area. The Bay Area co-lead agencies have committed to reassess the attainment assessment in 2003 using data from the Central California Ozone Study and to submit a revised SIP to U.S. EPA in 2004 with any needed modifications to the control strategy.
On November 30, 2001, ARB submitted the 2001 Plan to U.S. EPA for approval as a revision to the California SIP. To support the on-road motor vehicle emission inventory and transportation conformity budgets in the Plan, ARB also transmitted the San Francisco Bay Area-EMFAC2000 model to U.S. EPA for approval for the Bay Area.

1999 Ozone Plan
|The ARB held a public hearing on July 22,
1999 to consider the San Francisco Bay Area Ozone Attainment Plan for
the 1-Hour National Ozone Standard (1999 Bay Area Plan) as a revision
to the California State Implementation Plan (SIP). The Plan includes a
1995 emission inventory for volatile organic compounds (VOC) and
nitrogen oxides (NOx); an assessment of the emission reductions needed
to attain the ozone standard by 2000; a control strategy; a new
transportation conformity budget; and contingency measures. The
District is committing to adopt new controls for polystyrene
manufacturing, organic liquid storage, and gasoline dispensing
facilities, as well as two new measures affecting aeration of
