Air Plan Approval; Massachusetts; Infrastructure State Implementation Plan Requirements for the 2015 Ozone Standard

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision submitted by the State of

Massachusetts. Except as noted, this revision satisfies the infrastructure requirements of the Clean Air Act (CAA) for the 2015 ozone National Ambient Air Quality Standards (NAAQS). The infrastructure requirements are designed to ensure that the structural components of each state's air quality management program are adequate to meet the state's responsibilities under the CAA. We are proposing to issue a finding of failure to submit pertaining to various aspects of the prevention of significant deterioration (PSD) requirements of infrastructure SIPs. The Commonwealth has long been subject to a Federal Implementation Plan (FIP) regarding PSD, thus a finding of failure to submit will result in no state sanctions or further FIP requirements. We do not in this action address CAA requirements regarding interstate transport, because we previously approved the Commonwealth's submittal addressing these requirements for the 2015 ozone standard (January 31, 2020). This action is being taken in accordance with the Clean Air Act.

SUPPLEMENTARY INFORMATION:

In the Final Rules section of this issue of the

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 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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 issue of the

Federal Register
