###### Environmental Protection Agency

          - 40 CFR Part 52 
          - [EPA-R03-OAR-2012-0271; FRL-9664-1] 

# AGENCY:

Environmental Protection Agency (EPA). 

# ACTION:

Proposed rule.

# SUMMARY:

                        EPA proposes to approve the State Implementation Plan (SIP) revision submitted by the Maryland Department of Environment to revise the Maryland State Implementation Plan (SIP). The revision removes a 1980 Consent Order issued to the Maryland Slag Company (now known as MultServ). The 1980 Consent Order is no longer required to satisfy applicable Federal regulations and 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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.
