02-21559. Approval and Promulgation of State Implementation Plans; Arizona State Implementation Plan Revision, Maricopa County Environmental Services Department

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA is proposing to approve revisions to the Arizona State Implementation Plan (SIP) for the Maricopa County Environmental Services Department (MCESD). The revisions consist of negative declarations for twelve volatile organic compound source categories for the MCESD. The intended effect of this action is to bring the MCESD portion of the Arizona SIP up to date in accordance with the requirements of the Clean Air Act, as amended in 1990 (CAA or the Act). EPA is proposing the approval of these negative declarations for the MCESD portion of the Arizona SIP under provisions of the CAA regarding EPA action on SIP submittals, SIPs for national primary and secondary ambient air quality standards, and plan requirements for nonattainment areas. EPA is approving these revisions in accordance with the requirements of the CAA.

DATES:

Comments must arrive by September 25, 2002.

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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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.

Authority: 42 U.S.C. 7401 et seq.
