The Honorable Herman Dillon, Sr. Chairman, Tribal Council Puyallup Tribe of Indians 3009 East Portland Avenue Tacoma, Washington 98404 RE: Offer for Consultation and Coordination on EPA's Proposed Approval of the Puget Sound Clean Air Agency Regulations Dear Chairman Dillon: The U.S. Environmental Protection Agency (EPA) is taking steps to address the backlog of older State Implementation Plan (SIP) revisions not acted upon at the time of submission. On February 4, 2005, and August 2, 2006, the EPA received submissions from the State of Washington requesting approval oCPuget Sound Clean Air Agency (PSCAA) regulatory changes adopted in 2003, 2004, and 2005. The PSCAA regulations apply on non-trust land and the airshed surrounding the Puyallup Reservation consistent with the Puyallup Tribe of Indians Land Claims Settlement Act. Since the PSCAA regulatory changes have been in place for nearly a decade, the EPA does not anticipate significant impact in proposing approval of these rules into the SIP. Nevertheless, on behalf of EPA, I would like to offer an opportunity for consultation and coordination on the actions. The first PSCAA regulatory change involves Regulation I, Section 12.03 "Continuous Emission Monitoring System." The EPA last approved Section 12.03 on August 31, 2004, (69 FR 53007). At that time, the EPA was concerned that language contained in Section 12.03 could be construed to limit the EPA's independent enforcement authority with respect to continuous emissions monitoring at a facility under a permit or order. The PSCAA satisfied the EPA's enforcement concern and committed to revising the regulations within six months (see 69 FR 53008). The SIP revision submitted on February 4, 2005 includes the updated PSCAA regulatory language and resolves the EPA's concern. The remaining regulatory changes involve Regulation II, Section 3.04 "Motor Vehicle and Mobile Equipment Coating Operations" and Section 3,11 "Coatings and Ink Manufacturing." These regulations were put in place by the PSCAA in 1991 to control volatile organic compound emissions and ozone formation. Subsequently, in 1998 and 2003, the EPA passed nationwide standards for auto refinishing and miscellaneous coatings, respectively. The revised PSCAA regulations submitted in 2005 and 2006 rely on the more stringent national standards rather than having duplicative local and national standards. As previously noted, the PSCAA regulatory changes have been in place for nearly a decade, so the EPA anticipates this proposed approval will not significantly impact the local community.
