2010-20726. Outer Continental Shelf Air Regulations Consistency Update for Massachusetts

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule-consistency update.

SUMMARY:

EPA is proposing to update to a portion of the Outer Continental Shelf (“OCS”) Air Regulations. Requirements applying to OCS sources located within 25 miles of States' seaward boundaries must be updated periodically to remain consistent with the requirements of the corresponding onshore area (“COA”), as mandated by the Clean Air Act (“the Act”). The portion of the OCS air regulations that is being updated pertains to the requirements for OCS sources in the Commonwealth of Massachusetts. The intended effect of approving the OCS requirements for the Commonwealth of Massachusetts is to regulate emissions from OCS sources in accordance with the requirements onshore. The change to the existing requirements discussed below is incorporated by reference into the Code of Federal Regulations and is listed in the appendix to the OCS air regulations.

SUPPLEMENTARY INFORMATION:

In the Final Rules Section of this Federal Register, EPA is incorporating applicable provisions of 310 Code of Massachusetts Regulations (CMR) 4.00: Timely Action Schedule and Fee Provisions, as amended through September 4, 2009 and 310 CMR 6.00: Ambient Air Quality Standards for the Commonwealth of Massachusetts, 310 CMR 7.00: Air Pollution Control, and 310 CMR 8:00: The Prevention and/or Abatement of Air Pollution Episode and Air Pollution Incident Emergencies, as amended through May 20, 2010 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 rule, 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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. Please note that if EPA receives adverse comment on an amendment, paragraph, or section of this rule and if that provision may be severed from the remainder of the rule, EPA may adopt as final those provisions of the rule that are not the subject of an adverse comment.

For additional information, see the direct final rule which is located in the Rules Section of this Federal Register.
