As part of Ecology’s process to reissue the Phase II Municipal Stormwater General Permits in July 2012, Ecology must evaluate possible new permittees for coverage.
The federal rule to implement the NPDES program requires that Ecology evaluate possible new permittees for coverage under the NPDES Phase II stormwater municipal permits.
Ecology's permits authorize stormwater discharges to surface water from municipal separate storm sewer systems that are:
Ecology began working in summer 2011 with the following cities that met these population thresholds in the 2010 U.S. Census:
Ecology's evaluation also includes the unincorporated Urban Growth Areas (UGA’s) around cities over 10,000 that became permittees in 2007. This is consistent with the UGA’s of all the other Phase II cities, for which permit coverage began in 2007. Ecology met with the following counties during summer 2011 to inform them of the evaluation process and to request information related to the criteria for coverage through petition:
Ecology has completed its evaluation of the following jurisdictions and determined that at this time they do not meet the criteria for permit coverage:
City of Moxee
City of Woodway
City of Cheney
Grant County for the Moses Lake UGA
Skagit County for the Anacortes UGA
After evaluation of the Yakima County portion of the Sunnyside UGA, Ecology proposes to expand Yakima County’s coverage area in the 2013-2018 permit to include the unincorporated Sunnyside UGA.
Ecology has not yet completed evaluations for these jurisdictions, and as a result, listed them as proposed permittees in the October 2011 draft permit pending further evaluation. If the evaluation determines that these proposed coverage areas meet the criteria, Ecology will include them as new permittees in the final June 2012 permit for the August 1, 2013 to July 31, 2018 permit term:
Cities of Lynden, Snoqualmie, and Grandview
Clallam County for the Port Angeles UGA
Island County for the Oak Harbor UGA
Lewis County for the Centralia UGA
Kittitas County for the Ellensburg UGA
