2017-24114. Approval and Promulgation of Air Quality Implementation Plans; Maryland; Continuous Opacity Monitoring Requirements for Municipal Waste Combustors

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

The Environmental Protection Agency (EPA) proposes to approve the Clean Air Act (CAA) section 111(d)/129 State Plan revision submitted by the State of Maryland for the purpose of updating municipal waste combustor (MWC) references to opacity monitor quality assurance and quality compliance requirements in Regulations .07 and .08 under the Code of Maryland Regulations (COMAR) 26.11.08. In the Final Rules section of this Federal Register, EPA is approving Maryland's State Plan 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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.

DATES:

Comments must be received in writing by December 6, 2017.
