Approval and Promulgation of Implementation Plans: Washington and Oregon

Pursuant to procedures described in the January 19, 1989 Federal Register, EPA recently approved a number of minor State Implementation Plan (SIP) revisions submitted by the Washington Department of Ecology (WDOE) and the Oregon Department of Environmental Quality (ODEQ). These revisions included; local air pollution control regulations submitted by WDOE from the Puget Sound Air Pollution Control Agency (PSAPCA) which adjust civil penalty and registration fee amounts to cover program costs and which update delegations for Federal New Source Performance Standards (NSPS) and National Emission Standard for Hazardous Air Pollutants (NESHAPS); the repeal of two WDOE regulations which have no adverse impact on air quality; and a revision from ODEQ to better define existing air quality control regions and nonattainment and maintenance areas of Oregon (the revision did not change any existing boundaries). This document lists the revisions EPA approved and incorporates the relevant material into the Code of Federal Regulations.
