[EPA-R03-OAR-2012-0272; FRL-9702-5]

Approval and Promulgation of Air Quality Implementation Plans; 
Maryland; Control of Iron and Steel Production Installations; Sintering 
Plants

AGENCY: Environmental Protection Agency (EPA).

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will be withdrawn and all public comments received will be addressed in 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.

means EPA will not know your identity or contact information unless you 
provide it in the body of your comment. If you send an email comment 
directly to EPA without going through www.regulations.gov, your email

comment, EPA recommends that you include your name and other contact 
information in the body of your comment and with any disk or CD-ROM you 
submit. If EPA cannot read your comment due to technical difficulties 
and cannot contact you for clarification, EPA may not be able to 
consider your comment. Electronic files should avoid the use of special

viruses.
    Docket: All documents in the electronic docket are listed in the 
www.regulations.gov index. Although listed in the index, some

whose disclosure is restricted by statute. Certain other material, such 
as copyrighted material, is not placed on the Internet and will be 
publicly available only in hard copy form. Publicly available docket
