**Approval and Promulgation of Air Quality Implementation Plans;**  **Minnesota**

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

**ACTION :**  Proposed rule.

**SUMMARY :**  EPA is proposing to approve Minnesota’s request to amend its State Implementation Plan (SIP) for sulfur dioxide (SO 2). The Minnesota Pollution Control Agency submitted the SIP revision request to EPA on May 7, 2010. The proposed approval revises the Minnesota SIP by updating information regarding the heat and steam distributor facility located in Fridley, Minnesota. The source, formerly operated as United Defense, LP, Inc. was sold and is now operating as ELT Minneapolis, LLC. The revision replaces the joint Title I/Title V document currently approved in the SIP for the facility to reflect the change in ownership. These revisions do not change any of the SO 2 control requirements and will not result in an increase in SO 2 emissions at the facility because no emission limits were increased.

**SUPPLEMENTARY INFORMATION :**  In the Rules section of this Federal Register, EPA is approving the State’s SIP submittal as a direct final rule without prior proposal because EPA 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 adverse comments are received in response to this rule, 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period. Any parties interested in commenting on this action should do so at this time. Please note that if EPA receives adverse comment on an amendment, paragraph, or section of this rule and if that provision may be severed from the remainder of the rule, EPA may adopt as final those provisions of the rule that are not the subject of an adverse comment. For additional information, see the direct final rule which is located in the Rules section of this Federal Register.

**Approval and Promulgation of Implementation Plans and**  **Designations of Areas for Air Quality Planning Purposes; Tennessee:**  **Knoxville; Determination of Attainment for the 1997 8-Hour Ozone Standards** 

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

**ACTION :**  Proposed rule.

**SUMMARY :**  On February 19, 2010, the State of Tennessee, through the Tennessee Department of Environment and Conservation (TDEC), submitted a request to EPA to make a determination that the Knoxville, Tennessee nonattainment area has attained the 1997 8-hour ozone national ambient air quality standards (NAAQS) based on quality assured, quality controlled monitoring data from 2007–2009. The Knoxville, Tennessee 1997 8-hour ozone nonattainment area (hereafter referred to as the ‘‘Knoxville Area’’) is comprised of Anderson, Blount, Jefferson, Knox, Loudon and Sevier Counties in their entireties and a portion of Cocke County (Great Smoky Mountain National Park) in Tennessee. In this action, EPA is proposing to determine that the Knoxville Area has attained the 1997 8- hour ozone NAAQS. This proposed determination is based upon complete, quality assured, quality controlled, and certified ambient air monitoring data for the years 2007–2009 showing that the Knoxville Area has monitored attainment of the 1997 8-hour ozone NAAQS. Preliminary air quality monitoring data available for 2010 are consistent with continued attainment. If this proposed determination is made final, the requirement for the State of Tennessee to submit an attainment demonstration and associated reasonably available control measures (RACM), a reasonable further progress (RFP) plan, contingency measures, and other planning State Implementation Plans (SIPs) related to attainment of the 1997 8-hour ozone NAAQS for the Knoxville, Tennessee 8-hour ozone nonattainment area, shall be suspended for as long as the Knoxville Area continues to meet the 1997 8-hour ozone NAAQS.
