• The Washington State Department of Ecology (Ecology) is pleased to provide this application for federal authorization ofseveral rules. Ecology is asking for authorization ofthe rules which are listed on the next two pages. This authorization will supplement Washington's authorization for the Core RCRA Program and three subsequent program revisions. This application is submitted pursuant to the requirements of 40 CFR Part 271. The package consists of a revised program description, an Attorney General's Statement, Revision Checklists, and copies of other appropriate documents. It has been determined that this program revision does not require any changes to the Memorandum ofAgreement (MOA), dated November 26, 1985. The MOA is supplemented by two addenda, dated July 25, 1988, and September 1994. I understand that both of our agencies have devoted considerable resources to the development and coordination of this application. I trust that our mutual investment willspeed the authorization process. If you or your staffhave any questions, please contact Megan White of my staff at (360) 407-6702. Sincerely,
