Dear Ms. Jordan: 

The Air Resources Board (ARB) is pleased to submit to the U.S. Environmental 

Protection Agency (U.S. EPA) five local air district 2006 Reasonably Available Control 

Technology State Implementation Plans (RACT) (SIP) as a revision to the California 

SIP. The five districts are the Ventura County Air Pollution Control District, the South 

Coast Air Quality Management District (which also adopted the Coachella Valley 

nonattainment area plan), the San Joaquin Valley Air Pollution Control District, the 

Yolo-Solano Air Quality Management District, and the Antelope Valley Air Quality 

Management District. These RACT SIPS are for 8-hour ozone nonattainment areas that 

have to date adopted their RACT SIPs. 

RACT evaluations and analyses are required for specific stationary sources for which 

U.S. EPA had published Control Technique Guidelines (CTG) and for major non-CTG 

stationary sources (70 FR 71612, 71617, Nov. 29, 2005). U.S. EPA requires districts to 

review existing rules for CTG sources and major non-CTG sources within the district to 

determine if .those rules continue to nieet RACT. 

In parallel to the RACT SIP effort, nonattainment areas for the 8-hour ozone standard 

are preparing their attainment SIPs. These attainment SIPS will address the full suite of 

local and statewide measures that will be required to bring these areas into attainment. 

Because of California's long history of vigorous air pollution control, this round of RACT 

SIPS provides only a fraction of the additional reductions needed for attainment. ARB 

and the districts are currently refining air quality modeling to determine the specific 

amount of emission reductions needed. Concurrently, ARB and the districts are 

identifying, through a public process, controls to provide the necessary additional 

reductions. 

ARB staff has determined ,that these RACT SIPS have met the criteria for completeness, 

including public notice and public comment process prior to district adoption of their 

plans. Public comments received by local air districts are contained within each 

The energy challenge facing California is real. Every Californian needs to take immediate action to reduce energy consumption.
