Submittal of2012 Air Quality Management Plan Dear Mr. Goldstene and Ms. Jordan, At its December 7, 2012 meeting, the South Coast Air Quality Management District (SCAQMD) Governing Board adopted the 2012 Air Quality Management Plan (AQMP or Plan). The 2012 

### AQMP, as approved, is submitted addressing the following Federal Clean Air Act requirements:

• 24-hour PM2.5 Plan
• 8-hour ozone additional measures and vehicle miles traveled (VMT) offset demonstration • 1-hour ozone attainment demonstration and VMT offset demonstration Our agency would appreciate an expedited staffreview and California Air Resources Board (CARB) consideration at the earliest possible date. Changes indicated in underline and strikeout format in Attachment F to the Board Letter and the Errata sheet, as well as motions described below, have been incorporated in the attached Final 2012 AQMP. The Governing Board approved two motions along with the adoption ofthe 2012 AQMP. The first motion was to remove CTS-04 from the 2012 AQMP, which contains the low vapor pressure (LVP) exemption issue, and prepare a letter from SCAQMD Chairman Dr. Burke to CARB Chairman Nichols requesting a study which evaluates whether some ofthe exempt LVP substances contribute to ozone and should be further controlled for ozone attainment purposes. 

### The letter will offer our technical assistance and possible funding assistance for each study, and emphasize the need to partner with affected businesses in conducting such a study.
