Abstract
Environmental Protection Agency (EPA) approves the revisions to the Washington State Implementation Plan (SIP) submitted by the Washington Department of Ecology on March 2, 1999 amending two portions of the Spokane County Air Pollution Control Agency's (SCAPCA) Regulation I, Article IV. The revisions to the SIP for the Spokane particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM10) nonattainment area simply adds a definition so that previously approved control measures would continue to be implemented should the area be redesignated as attainment or the pre-existing PM-10 standard is revoked.
