SUBJECT:Revisions to the Sacramento County Portion of California’s State Implementation Plan to Remove Control Measures SMAQMD – 412, IC Engines and SMAQMD – 471, Asphaltic Concrete
| Date | Tuesday, July 12, 2011 |
| Time | 10:00 a.m. |
| Location | Sacramento Metropolitan AQMD 777 12th Street, 3rd Floor Sacramento, California 95814 |
The Staff of the Sacramento Metropolitan AQMD will hold a public workshop for a proposed revision to the 2009 Sacramento Regional 8-Hour Ozone and Reasonable Further Progress Plan to remove the commitment to adopt control measures SMAQMD – 412, IC Engines and SMAQMD – 471, Asphalt Concrete. This revision will be submitted to the U.S. Environmental Protection Agency as an amendment to the California State Implementation Plan.
These measures would require equipment changes to reduce NOx emissions from internal combustion engines and at plants that produce asphalt. Since the approval of the Plan, several factors have led Staff to recommend these revisions. These factors include:
- The emissions decreased since adoption of the Plan
- The estimated cost effectiveness of the measures, in dollars per pound of NOx emissions reduced, has more than quadrupled what was estimated in the Plan
This revision complies with the Clean Air Act (CAA) Section 110(l) because it will not change or interfere with the attainment demonstration (CAA Sections 172(c)(1) and 182(c)(2)(A)), or reasonable further progress demonstration (CAA Sections 182(c)(2)(B) and (C)), and will not change the reasonably available control measures conclusions (CAA Section 172(c)(1)) or contingency measure conclusions (CAA Section 172(c)(9) and 182(c)(9)).
