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 to the EPA by the State of Montana. On September 19, 2016, the Governor of Montana's designee submitted a Clean Air Act (CAA) section 175A(b) second 10-year limited maintenance plan for the Missoula area for the carbon monoxide (CO) National Ambient Air Quality Standard (NAAQS). This limited maintenance plan addresses maintenance of the CO NAAQS for a second 10-year period beyond the original redesignation. This action is being taken under sections 110 and 175A of the CAA.

SUPPLEMENTARY INFORMATION:
In the “Rules and Regulations” section of today's Federal Register, the EPA is approving Montana's SIP revision as a direct final rule without prior proposal because the Agency views this as a noncontroversial SIP revision and anticipates no adverse comments. A detailed rationale for the approval is set forth in the preamble to the direct final rule. If the EPA receives no adverse comments, the EPA will not take further action on this proposed rule. If the EPA receives adverse comments, the EPA will withdraw the direct final rule and it will not take effect. The EPA will address all public comments in a subsequent final rule based on this proposed rule. The EPA will not institute a second comment period on this action. Any parties interested in commenting must do so at this time. For additional information, see the direct final action, with the same title, that is located in the “Rules and Regulations” section of this issue of the Federal Register.
