**ACTION :**  Proposed rule.

**SUMMARY :**  The Environmental Protection Agency (EPA) is proposing to approve revisions to the State Implementation Plan (SIP) for the State of Iowa to include modified permits for Muscatine County, Iowa. The SIP revision addresses modifications to construction permits that were included in the 2006 24-hour particulate matter less than 2.5 micrometers (PM2.5 ) National Ambient Air Quality Standards (NAAQS) control strategy proposed on August 11, 2014, and published as a final rule in the Federal Register on December 1, 2014, with the effective date of December 31, 2014. The state’s submission of modified permits includes a revised air dispersion modeling analysis that demonstrated continued attainment of the 2006 24-hour PM 2.5 NAAQS. This action will also make an administrative correction to permit numbers.

. **SUPPLEMENTARY INFORMATION :**  In the final rules section of the Federal Register , EPA is approving the state’s revision to the SIP as a direct final rule without prior proposal because the Agency views this as a noncontroversial revision amendment and anticipates no relevant adverse comments to this action. The detailed rationale for the approval is set forth in the technical support document that can be found in Docket ID No. EPA–R07–OAR–2015– 0159. If no relevant adverse comments are received in response to this action, no further activity is contemplated in relation to this action. If EPA receives relevant adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rules based on this proposed action. EPA will not institute a second comment period on this action. Any parties interested in commenting on this action should do so at this time. Please note that if EPA receives adverse comments on part of this rule and if that part can be severed from the remainder of the rule, EPA may adopt as final those parts of the rule that are not the subject of an adverse comment.

**Regulation of Fuels and Fuel Additives: Cellulosic Waiver Credit**  **Price and Minor Amendments to Renewable Fuel Standard Regulations** 

**AGENCY :**  Environmental Protection Agency (EPA).

**ACTION :**  Proposed rule.

**SUMMARY :**  The Environmental Protection Agency (EPA) is proposing to clarify our regulations related to the data sources used to establish the cellulosic waiver credit (CWC) price. We are also proposing to remove references to CWC prices from the renewable fuel standard regulations, and instead intend to post the prices on EPA’s Web site. This proposed rule also indicates what the CWC prices for 2014 and 2015 would be using the data sources and methodology contained in the rule; however these prices will not be established until they are posted on our Web site following the effective date of the rule. In addition, we are proposing minor amendments to the renewable fuel standard program regulations to reinsert sections inadvertently overwritten by the Quality Assurance Program final rule published on July 18, 2014. In the ‘‘Rules and Regulations’’ section of this Federal Register , we are making these same amendments as a direct final rule. If we receive no adverse comment, the direct final rule will go into effect and we will not take further action on this proposed rule.

**DATES :**  A request for a public hearing must be received by April 20, 2015. If a public hearing request is received, EPA will publish a notice in the Federal Register indicating the time and place for the hearing. If a public hearing is held, written comments must be received within 30 days after the date of the hearing. If no public hearing is held then comments must be received on or before May 4, 2015.
