2014-05667. Approval and Promulgation of Implementation Plans; State of Arizona; Payson PM10

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

Pursuant to the Clean Air Act (CAA), the Environmental Protection Agency (EPA) is proposing to approve a revision to the Payson portion of the Arizona State Implementation Plan submitted by the Arizona Department of Environmental Quality on January 23, 2012. This revision consists of the second ten-year maintenance plan for the Payson air quality planning area for the national ambient air quality standards (NAAQS) for particulate matter less than 10 microns in diameter (PM₁₀). EPA is proposing to approve this plan based on the conclusion that the plan adequately provides for continued maintenance of the PM₁₀ NAAQS in the Payson area through 2022. EPA is proposing this action pursuant to those provisions of the CAA that obligate the Agency to take action on submittals of revisions to SIPs. The effect of this action would be to make the State's continuing commitments with respect to maintenance of the PM₁₀ NAAQS in the Payson area federally enforceable for another ten years.

Any comments on this proposal must arrive by April 18, 2014.

SUPPLEMENTARY INFORMATION:

This proposal addresses the Final Update of the Limited Maintenance Plan for the Payson PM ₁₀ Maintenance Area (December 2011) (“Second Ten-Year Limited Maintenance Plan”) submitted as a revision to the Arizona State Implementation Plan (SIP) on January 23, 2012 by the Arizona Department of Environmental Quality. In the Rules and Regulations section of this Federal Register, we are approving the Second Ten-Year Limited Maintenance Plan for the Payson area 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 we receive adverse comment on an amendment, paragraph, or section of this rule and if that provision may be severed from the remainder of the rule, we 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.

Dated: March 5, 2014.

Jared Blumenfeld,

Regional Administrator, Region IX.
