Approval and Promulgation of State Implementation Plans; California State Implementation Plan Revision, Mendocino County Air Quality Management District

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

SUMMARY: EPA is proposing to approve revisions to the California State Implementation Plan (SIP). This action is an administrative change which revises two definitions and adds one definition in Mendocino County Air Quality Management District (MCAQMD) Rule 130, Definitions.

The intended effect of proposing approval of this rule is to incorporate changes to the definitions for clarity and consistency with revised federal and state definitions. EPA is proposing approval of this revision to be incorporated into the California SIP for the attainment and maintenance of the national ambient air quality standards (NAAQS) under title I of the Clean Air Act, as amended in 1990 (CAA or the Act). In the Final Rules Section of this Federal Register, the EPA is approving the state's SIP revision as a direct final rule without prior proposal because the Agency views this as a noncontroversial revision amendment and anticipates no adverse comments. A detailed rationale for this approval is set forth in the direct final rule. If no relevant adverse comments are received in response to the direct final rule, no further activity is contemplated in relation to this proposed rule. If EPA receives relevant adverse comments, the direct final rule will not take effect and all public comments received will be addressed in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period. Any parties interested in commenting should do so at this time.

DATES: Comments must be received in writing by August 31, 1998.

ADDRESSES: Written comments on this action should be addressed to: Andrew Steckel, Rulemaking Office (AIR-4), Air Division, U.S. Environmental Protection Agency, Region 9, 75 Hawthorne Street, San Francisco, CA 94105-3901.

Copies of the rule revisions and EPA's evaluation report of each rule are available for public inspection at EPA's Region 9 office during normal business hours. Copies of the submitted rule revisions are also available for inspection at the following locations:
