Re: Completeness Determination for the Multi-pollutant Infrastructure SIP Submission

Dear Mr. Clark: This letter is in response to your September 22, 2014 submission related to Clean Air Act (CAA) sections 1 l0(a)(1) and (2), "Infrastructure SIP Revision for the 2010 Nitrogen Dioxide, 2008 Ozone, and 1997, 2006, and 2012 Fine Particulate Matter National Ambient Air Quality Standards." This submission is intended to demonstrate that the State of Washington has the necessary infrastructure to implement the air quality management requirements set forth in sections 110(a)(1) and (2) of the CAA with respect to these air quality standards. Specifically, Washington's submission addresses the following CAA section 110(a)(2) infrastructure elements: (A), (B), (C) - except for those elements covered by the Prevention of Significant Deterioration (PSD) Federal Implementation Plan (FIP), (D)(i)(II) - except for those elements covered by the PSD and regional haze FIPs, (D)(ii) - except for those elements covered by the PSD FIP, (E), (F), (G), (H), (J) - except for those elements covered by the PSD FIP, (K), (L), and (M). The Environmental Protection Agency (EPA) notes that the Washington Department of Ecology (Ecology) intends to address the CAA section 110(a)(2)(D)(i)(I) interstate transport provisions in a separate submittal. The EPA has determined that the submission is complete for the specific elements described above for the air quality standards addressed. The EPA also notes that on January 27, 2014, Ecology submitted significant updates to Chapter 173-400 Washington Administrative Code (WAC), including provisions covering Ecology's PSD program. The EPA has already acted upon parts of the January 27, 2014 submittal, but we have not yet completed our review of Ecology's PSD program. The EPA also notes that the January 27, 2014 submission only covers PSD requirements for sources under Ecology's jurisdiction. So even after a final determination is made by the EPA regarding the January 27, 2014 submission, Ecology's PSD submission would not be considered complete for the PSD infrastructure requirements because it does not cover all facilities in Washington, such as those under the jurisdiction of the Energy Facilities Site Evaluation Council. As discussed in previous infrastructure actions for both ozone and lead (77 FR 30902, May 24, 2012 and 79 FR 42683, July 23, 2014), the EPA anticipates that there would be no adverse

and regional haze FIPs to satisfy infrastructure requirements. The EPA anticipates no additional FIP responsibilities for PSD and regional haze as a result of the determination that the September 22, 2014 infrastructure submission is not complete for those elements. We note that we are working with Ecology on a separate submission addressing the remaining CAA section 110(a)(2)(D)(i)(I) interstate transport requirements. If you have any questions please feel free to contact me at (206) 553-1271 or have your staff contact Debra Suzuki, Air Planning Unit Manager, at (206) 553-0985 or Jeff Hunt, staff lead, at 206-553-0256. Sincerely,
