NOTICE OF PUBLIC HEARING

WASHINGTON STATE DEPARTMENT OF ECOLOGY

Including Revised Spokane County Air Pollution Control

Authority Regulatory Orders in the Washington State Implementation Plan



The Washington State Department of Ecology is conducting a public hearing to receive comments on including revised Spokane County Air Pollution Control Authority (SCAPCA) regulatory orders in the state implementation plan (SIP). The SIP is a state-wide plan for meeting federal health-based air quality standards. The hearing will be held during the SCAPCA board meeting at 8:30 a.m. on Thursday, October 5, 2000, at the Spokane County Public Works Building, Commissioners' Hearing Room, Lower Level, 1026 West Broadway, Spokane, WA.

SCAPCA has proposed revised Orders #96-03, #96-05, and #96-06 to replace the orders currently in the SIP. SCAPCA adopted Orders #96-03, #96-04, #96-05, and #96-06 in 1996 to limit potential emissions from the Kaiser Trentwood facility in Spokane. Kaiser voluntarily accepted these regulatory orders under WAC 173-400-091 to maintain the validity of the modeling of the Kaiser Trentwood facility in the Spokane PM10 attainment plan. EPA adopted the four regulatory orders into Washington state's federally approved SIP. Following finalization of the orders, it was discovered that some emissions were inadvertently omitted from the orders. Kaiser has requested revised orders to ensure that these emissions are addressed. The revised orders reduce potential PM10 emissions from the Kaiser Trentwood facility by 390 pounds per day and include revisions to allow for operational flexibility. For ecology's purposes, comments must be limited to including the revised orders in the SIP. Written comments must be postmarked no later than October 9, 2000, and should be sent to Doug Schneider, Department of Ecology, Air Quality Program, P.O. Box 47600, Olympia, WA 98504-7600.
