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 Plan (SIP) 

for the 2010 federal nitrogen dioxide (N02) standard. On November 15, 2012, the 

Board approved for adoption the N02 Infrastructure SIP which addresses the elements 

set forth in Clean Air Act (Act) Section 11 O(a)(2). As required under the Act, the N02 

Infrastructure SIP elements document that California's resources, programs, and 

authority are adequate to implement, attain, and enforce the 2010 federal N02 standard. 

Before being approved by the Board, the N02 Infrastructure SIP was available for a 

30-day public review. No changes have been made to the document since that time. 

This N02 Infrastructure SIP submittal includes one hard copy and one identical 

electronic copy of the following materials (enclosed). 

1. State Implementation Plan Revision forFederal Nitrogen Dioxide Standard 

Infrastructure Requirements (Staff Report which includes Appendix A): 

• "Appendix A: State Implementation Plan Revision for Federal 

Nitrogen Dioxide Standard Infrastructure Requirements" 

2. ARB Resolution 12-34 approving the State Implementation Plan Revision 

for Federal Nitrogen Dioxide Standard Infrastructure Requirements 

3. Public Hearing notice evidence of the November 15, 2012, Board Hearing 

to consider approval of the State Implementation Plan Revision for Federal 

Nitrogen Dioxide Standard Infrastructure Requirements. 

4. Comments received in response to the Public Hearing notice. 

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

For a list of simple ways you can reduce demand and cut your energy costs, see our website: http://www.arb.ca.gov.
