05-20417. Approval and Promulgation of Air Quality Implementation Plans; Connecticut; Redesignation of City of New Haven PM10

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

The EPA is proposing to approve a State Implementation Plan (SIP) revision submitted by the State of Connecticut. This revision establishes a Limited Maintenance Plan (LMP) for the New Haven PM₁₀ nonattainment area (New Haven NAA) in the State of Connecticut and grants a request by the State to redesignate the New Haven NAA to attainment for the National Ambient Air Quality Standards (NAAQS) for particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM₁₀). EPA is approving this redesignation and LMP because Connecticut has met the applicable requirements of the Clean Air Act (CAA).

SUPPLEMENTARY INFORMATION:

In the Final Rules Section of this Federal Register, EPA is approving Connecticut'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 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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.
