Dennis M. McLerran, Regional Administrator U.S. Environmental Protection Agency, Region 10 1200 Sixth Avenue, Suite 900 Seattle, WA 98101-3140 RE: Tacoma-Pierce County Nonattainment Area SIP revision Dear Mr. McLerran: As the Governor's designee for the State Implementation Plan (SIP), I am submitting this SIP revision for the Tacoma-Pierce County Nonattainment Area (Nonattainment Area) for your approval as a part of the Washington SIP. The SIP revision details Washington's plan to improve air quality in the Nonattainment Area. The Washington State Department of Ecology (Ecology) adopted the SIP revision effective November 28, 2012. On September 4, 2012, EPA made a Clean Data Determination for the Nonattainment Area which suspended most SIP planning requirements. I am submitting the following:

• The required 2008 baseline emissions inventory for the Nonattainment Area (Appendix A to the SIP revision) for EPA approval.
• Puget Sound Clean Air Agency's (PSCAA) Regulation 1-13 Solid Fuel Burning Devices (Appendix B) for EPA approval. This rule will improve air quality in the Nonattainment Area and strengthen the Washington SIP. The PSCAA Board adopted this regulation on October 25, 2012 in accordance with state law. The rule will be effective December 1, 2012. Ecology's public notice clearly stated that we would submit these rules to EPA for approval. Ecology published notice in two Washington State newspapers on September 10, 2012 which meets the requirement for 31 days advance notice of the hearing. Ecology received oral testimony and written comments. The SIP revision includes a compilation of public comments Ecology received and Ecology's responses to those comments (Appendix G). The SIP revision includes a certification that Ecology held the public hearing in accordance with public notice and the public hearing requirements of 40 CFR §51.102. Ecology met all state and federal procedural requirements.Dennis M. McLerran, Regional Administrator
