Approval and Promulgation of Implementation Plans; California

State Implementation Plan Revision; South Coast Air Quality Management

District; Ventura County Air Pollution Control District; Mojave Desert

Air Quality Management District

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: EPA proposes to approve revisions to the California State

Implementation Plan (SIP). Two rules to be approved into the SIP

control volatile organic compound (VOC) emissions from storage tank

cleaning and degassing operations and from components at crude oil and

natural gas production and processing facilities. Two rules to be

removed from the SIP control VOC emissions from pumps, compressors, and

relief valves.

The intended effect of this action is to regulate emissions of VOCs

in accordance with the requirements 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 submittal as a direct

final rule without prior proposal because the Agency views this as a

noncontroversial revision and anticipates no adverse comments. A

detailed rationale for this approval is set forth in the direct final

rule. If no adverse comments are received, no further activity is

contemplated. If EPA receives adverse comments, the direct

[[Page 45216]]

final rule will be withdrawn and all public comments received will be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 should do so at this time.

DATES: Written comments must be received by September 20, 1999.

ADDRESSES: Comments should be addressed to: Andrew Steckel, Rulemaking

Office (AIR-4), Air Division, U.S. Environmental Protection Agency,

Region IX, 75 Hawthorne Street, San Francisco, CA 94105-3901.
