###### Environmental Protection Agency

          - 40 CFR Part 70
          - [EPA-R03-OAR-2007-0254; FRL-8304-9]

# AGENCY:

Environmental Protection Agency (EPA).

# ACTION:

Proposed rule.

# SUMMARY:

                        EPA proposes to approve the operating permit program revision submitted by the State of Maryland for the purpose of amending the Code of Maryland Administrative Regulations' (COMAR) incorporation by reference citations to ensure that future changes to the Federal Acid Rain program will continue to be incorporated into Maryland's regulations. In the Final Rules section of this                         **Federal Register**                        , EPA is approving the State's operating permit program revision 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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 May 25, 2007.
