Dear Mr. Blumenfeld: 

Governor 

The Air Resources Board (ARB or Board) is submitting to the U.S. Environmental 

Protection Agency (U.S. EPA) revisions to California's State Implementation Plans (SIP) 

for the federal fine particulate matter (PM2.5) standard. ·On April 28, 2011, the Board 

approved for adoption revisions to the South Coast and San Joaquin Valley PM2.5 SIPs 

primarily to account for State and local rulemaking actions that will reduce PM2.5 

precursor emissions by the 2014 attainment deadline. This SIP revision updates three 

elements of the PM2.5 SIPs for the South Coast and San Joaquin Valley: ARB's 

rulemaking calendar, transportation conformity budgets, and reasonable further 

progress calculations. Revisions to the local element of the South Coast PM2.5 SIP 

have also been approved by ARB and are being submitted under separate cover letter. 

The submittal includes one hard copy and one identical electronic copy of the following 

materials (enclosed): 

1. The Progress Report on Implementation of PM2.5 SIPs for the South Coast and 

San Joaquin Valley Air Basins and Proposed SIP Revisions (Progress Report 

and Proposed SIP Revisions). The Progress Report and Appendices "A", "E", 

and "G" are being transmitted for informational purposes. The specific SIP 

submittal that the Board approved for adoption is as follows: 

• Appendix B: Rulemaking Calendar. 

• Appendix C: Reasonable Further Progress Tables. 

• Appendix D: Transportation Conformity Budgets. 

2. ARB Resolution 11-24 approving the Progress Report and Proposed SIP 

Revisions. 

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