# AGENCY:

Environmental Protection Agency (EPA).

# ACTION:

Proposed rule.

# SUMMARY:

                        Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is proposing to approve portions of the revisions to the Arkansas State Implementation Plan (SIP) submitted by the Arkansas Department of Environmental Quality (ADEQ) on March 24, 2017. Most of the revisions are administrative in nature and make the SIP current with Federal rules. The EPA is also proposing to make ministerial changes to the Code of                         **Federal Register**                         (CFR) to reflect SIP actions pertaining to the Arkansas Prevention of Significant Deterioration (PSD) program.

# SUPPLEMENTARY INFORMATION:

                    In the final rules section of this issue of the                     **Federal Register**                    , the EPA is approving the State's SIP submittal as a direct rule without prior proposal because the Agency views this as 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 If the EPA receives relevant adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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 issue of the                     **Federal Register**                    .

Regional Administrator, Region 6.
