RE: Offer for Consultation and Coordination on the U.S. Environmental Protection Agency Review of 

and Action on the Second 1 0-Year Coarse Particulate Matter Limited Maintenance Plan for Kent, 

Seattle, and Tacoma 

Dear Chairman Dillon: 

Next month the Washington State Department of Ecology (Ecology), in coordination with the Puget 

Sound Clean Air Agency (PSCAA), plans to submit a limited maintenance plan for approval by the U.S. 

Environmental Protection Agency (EPA) covering the Kent, Seattle, and Tacoma Coarse Particulate 

Matter (PM10) maintenance areas. The EPA first identified these areas as violating the PM10 National 

Ambient Air Quality Standard (NAAQS) in 1987. Pollution control measures focused on fugitive dust, 

residential wood combustion, open burning, and industrial controls brought all three areas into 

compliance with the PM10 NAAQS by 1990. On March 13, 2001 , the EPA redesignated all three areas 

from "nonattainment" to "maintenance" triggering a twenty year obligation under section 175A of the 

Clean Air Act to demonstrate continued compliance with the PM10 NAAQS through the year 2020 (66 

FR 14492). 

A limited maintenance plan is a streamlined means of meeting section 175A Clean Air Act 

requirements for areas that demonstrate little risk of violating the PM10 NAAQS again. In accordance 

with the EPA's guidance, limited maintenance plans make no substantive changes to the overall control 

measures or the regulations already in place. Therefore, we believe potential action on all three areas 

would be noncontroversial and would have minimal impact on the Puyallup Tribe of Indians. We are 

expecting to be able to rely on the limited maintenance plan to meet the 175A Clean Air Act 

requirements for the Kent, Seattle, and Tacoma PM10 maintenance areas, including portions of the 

Puyallup Reservation. As a member of the PSCAA Advisory Council, you will have an opportunity at 

the October 9, 2013 Advisory Council meeting to review and modify the plan prior to submission to the 

EPA. Nevertheless, on behalf of the EPA, I would like to offer an opportunity for consultation and 

coordination on our review of and action on this plan. 

The EPA is offering you consultation and coordination in accordance with the EPA Policy on 

Consultation and Coordination with Indian Tribes (www.epa.gov/tribal/consultation/consultpolicy.htm). Please have your staff notify Jeff Hunt, at 206-553-0256, by November 1, 2013 if you are

interested in scheduling a consultation meeting or would like further information about any of these 

areas. Feel free to call me at 206-553-1271 if you have any questions.
