E9-22918. Approval and Promulgation of Air Quality Implementation Plans; Indiana; Lead (Pb) Maintenance Plan Update for Marion County

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA is proposing to approve a request submitted by the Indiana Department of Environmental Management (IDEM) on April 1, 2009, to revise the Indiana State Implementation Plan (SIP) for lead (Pb). The State has submitted an update to its Pb maintenance plan for Marion County for continued attainment of the 1.5 micrograms per cubic meter (μg/m³) National Ambient Air Quality Standard (NAAQS) promulgated in 1978. This update satisfies section 175A of the Clean Air Act (CAA), and is in accordance with EPA's May 10, 2000 approval of the State's Redesignation Request and Maintenance Plan for the Marion County Pb nonattainment areas. Additionally, this Pb maintenance plan satisfies the requirements for maintenance plans contained in the September 4, 1992 EPA memorandum entitled “Procedures for Processing Requests to Redesignate Areas to Attainment.”

SUPPLEMENTARY INFORMATION:

In the Final Rules section of this Federal Register, EPA is approving the State's SIP submittal as a direct final rule without prior proposal because the Agency views this as a noncontroversial submittal and anticipates no adverse comments. A detailed rationale for the approval is set forth in the direct final rule. If no adverse comments are received in response to this rule, 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period. Any parties interested in commenting on this action should do so at this time. 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. For additional information, see the direct final rule which is located in the Rules section of this Federal Register.

Dated: September 14, 2009.

Acting Regional Administrator, Region 5.
