40 CFR Part 52

[AZ 086-0017b; FRL-6438-2]

Approval and Promulgation of State Implementation Plans; Arizona

State Implementation Plan Revision, Maricopa County

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA proposes to approve revisions to the Arizona State

Implementation Plan (SIP) which concern the control of volatile organic

compounds (VOC) emissions from different surface coating operations

using primarily metal and plastic substrates and the aerospace

manufacturing and rework industry.

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

according to 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 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will be withdrawn and all public comments received will be addressed in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 October 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.

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:
