New Mexico submitted this limited maintenance plan to fulfill the second 10-year maintenance plan requirement, under section 175A(b) of the Clean Air Act (CAA), to ensure maintenance of the 1971 SO₂ NAAQS through 2025. The EPA is also proposing to approve a monitoring network modification for the area. The EPA is proposing to approve these revisions pursuant to the CAA.

SUPPLEMENTARY INFORMATION:

In the final rules section of this Federal Register, EPA is approving the State's request for a limited maintenance plan submitted on November 1, 2013, for the Grant County maintenance area for the 1971 sulfur dioxide SO₂ NAAQS 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 relevant 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule. The EPA will not institute a second comment period. Any parties interested in commenting on this action should do so at this time.

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