Approval and Promulgation of Implementation Plans; Washington; Removal of Obsolete Regulations

The Environmental Protection Agency (EPA) is proposing to remove outdated rules in the Code of Federal Regulations (CFR) for the State of Washington because they are unnecessary or obsolete. The EPA is also proposing to clarify regulations to reflect updated citations and more recent air quality monitoring data. These proposed actions make no substantive changes to the State Implementation Plan (SIP) and impose no new requirements. In the Final Rules section of this Federal Register, the EPA is approving these determinations as a direct final rule without prior proposal because the Agency views this as a noncontroversial action and anticipates no adverse comments. A detailed rationale for the approval is set forth in the direct final rule. If no adverse comments are received in response to this action, no further activity is contemplated. If the EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule. The EPA will not institute a second comment period. Any parties interested in commenting on this action should do so at this time.
