Revisions to the Arizona State Implementation Plan, Maricopa County Air Quality Department and Maricopa County

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA is proposing to approve revisions to the Maricopa County Air Quality Department (MCAQD) and Maricopa County portions of the Arizona State Implementation Plan (SIP). These revisions concern PM-10 emissions from open outdoor fires and indoor fireplaces at commercial and institutional establishments, primary and secondary MCAQD ambient air quality standards, and residential woodburning devices. We are proposing approval of local rules that regulate these emission sources under the Clean Air Act as amended in 1990 (CAA or the Act).

DATES:

Any comments on this proposal must arrive by December 9, 2009.

SUPPLEMENTARY INFORMATION:

This proposal addresses the approval of local MCAQD Rules 314 and 510 and MC Ordinance P-26. In the Rules and Regulations section of this Federal Register, we are approving these local rules in a direct final action without prior proposal because we believe this SIP revision is not controversial. If we receive adverse comments, however, we will publish a timely withdrawal of the direct final rule and address the comments in subsequent action based on this proposed rule.

Please note that if EPA receives adverse comment on an amendment, paragraph, or section of this rule and if that provision may be severed from the remainder of the rule, EPA may adopt as final those provisions of the rule that are not the subject of an adverse comment.

We do not plan to open a second comment period, so anyone interested in commenting should do so at this time. If we do not receive adverse comments, no further activity is planned. For further information, please see the direct final action.
