###### Environmental Protection Agency

          - 40 CFR Parts 52, 62, and 70
          - [EPA-R07-OAR-2017-0470; FRL-9967-50-Region 7]

# AGENCY:

Environmental Protection Agency (EPA).

# ACTION:

Proposed rule.

# SUMMARY:

                        The Environmental Protection Agency (EPA) is proposing to approve revisions to the Iowa the State Implementation Plan (SIP), the 111(d) plan, and the Operating Permits Program. These revisions update and clarify rules and make minor revisions and corrections. Approval of these revisions will ensure consistency between the state and Federally-approved rules, and ensure Federal enforceability of the state's revised air program rules. In the “Rules and Regulations” section of this                         **Federal Register**                        , we are approving the state's SIP revisions as a direct final rule without a prior proposed rule. EPA is taking direct final action because we view this as a noncontroversial action and anticipate no relevant adverse comment. We have explained our reasons for these actions in the Technical Support Document that is included with this docket. If we receive no adverse comment, we will not take further action on this proposed rule.                    

# DATES:

Comments must be received by October 16, 2017.

# SUPPLEMENTARY INFORMATION:

                    This document proposes to take action on the Iowa the SIP, the 111(d) plan, and the Operating Permits Program. We have published a direct final rule approving these revisions in the “Rules and Regulations” section of this                     **Federal Register**                    , because we view this as a noncontroversial action and anticipate no relevant adverse comment. We have explained our reasons for these actions in the Technical Support Document that is included with this docket. If we receive no adverse comment, we will not take further action on this proposed rule. If we receive adverse comment, we will withdraw the direct final rule and it will not take effect. We would address all public comments in any subsequent final rule based on this proposed rule. We do not intend to institute a second comment period on this action. Any parties interested in commenting must do so at this time.
