Commissioner

On January 30, 2008, the Massachusetts Department of Environmental Protection (MassDEP) submitted to your office the Massachusetts State Implementation Plan to Demonstrate Attainment of the National Ambient Air Quality Standard (NAAQS) for Ozone (the Attainment Demonstration SIP). In that submittal, MassDEP committed to adopt additional ozone control measu res. MassDEP has promulgated regulations implementin g additional controls in furtherance of that commitment. The regulations that we are submitting are:

• AIM Coatings and Consumer Products. On October 19, 2007, regulations were promulgated amending Best Available Controls for Consumer and Commercial Products, 310 CMR 7.25. These amendments further reduce emissions of volatile organic compounds (VOCs) from architectural and industrial maintenance (A IM) coatings and consumer products. They add a number of new product categories to the list of previously regulated product categories and reduce the VOC content limits for many of the /.**~** previously regulated products.

The amendments to Best Available Controls for Consumer and Commercial Products , 310 CMR 7.25(12), add an Alternative Compliance Plan (ACP) option to the consumer product regulations adopted in October 2007, which allows manufacturers of consumer products to average VOC emissions among products to meet overall VOC emissions limits.

### .· • Stage II Vapor Recovery On March 1 , 2009 , regulations were promulgated amending 310 CMR 7.24(6). The amendments require the installation of PV vent caps at facilities with certain types of Stage II systems, a control measure which MassDEP committed to in the Ozone SIP. These amendments also clarify sections ofthe Stage II regulations to improve faci lity compliance and update applicable program requirements
.

• Other Regulations We have also promulgated other minor regulatory revisions that were not part of the Attainment Demonstration SIP commitment. On March 6, 2009 regulations were promulgated to: 1) amend the definition ofVOC in 310 CMR 7.00 to add HFE-7300 to the list of exempt compounds; and 2) make a technical correction to 310 CMR 7.03(16) related to paint spray booths.

I am submitting these regulations for your approval and incorporation into the Ozone SIP pursuant to the procedures establi shed in Section 11 O(k) ofthe Clean Air Act. Should you or your staffhave any questions regarding this submittal, please contact Barbara Kwetz, Director of the Planning Division in the Bureau of Waste Prevention. (617-292- 5882).
