ACTION:

Proposed rule.

SUMMARY:

EPA proposes to approve revisions to the Maryland State Implementation Plan (SIP) submitted by the Maryland Department of the Environment (MDE) on June 30, 2009. The revisions amend the visible emissions requirements of the Maryland SIP's regulation for the Control of Iron and Steel Production Installations as they apply to sintering plants. The sintering plant located at the Sparrows Point steelmaking facility (Sparrows Point) is the only sintering plant located in the State of Maryland, and therefore the only source affected by these SIP revisions. The revisions exempt the sintering plant from the visible emissions section of the regulation for the Control of Iron and Steel Production Installations contingent upon the source's two wet scrubbers, used to control emissions of particulate matter, continuously monitoring compliance with specified pressure drop and flow rate operating parameters. EPA is approving these revisions because they provide for a continuous means of determining compliance with the applicable SIP emission rate for particulate matter from the sintering plant located at Sparrows Point, and because that emission rate has been demonstrated to protect and maintain the National Ambient Air Quality Standards (NAAQS) for PM10 (particulate matter consisting of particles with an aerodynamic diameter less than or equal to 10 micrometers). EPA is proposing to approve these revisions in accordance with the requirements of the Clean Air Act (CAA). 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 action, 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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.

Comments must be received in writing by August 27, 2012.
