Approval and Promulgation of Air Quality Implementation Plans; Wisconsin; Disapproval of PM2.5
EPA is proposing to disapprove a revision to Wisconsin's State Implementation Plan (SIP) submitted by the Wisconsin Department of Natural Resources (WDNR) in a letter dated May 12, 2011. The revision concerns permitting requirements relating to particulate matter of less than 2.5 micrometers (PM2.5). EPA is proposing to disapprove the revisions because they do not meet the 2008 PM2.5 SIP requirements.
Approval and Promulgation of Implementation Plans; Tennessee: Knox County Supplemental Motor Vehicle Emissions Budget Update
EPA is proposing to approve, through parallel processing, a draft revision to the Tennessee State Implementation Plan (SIP), submitted to EPA on October 12, 2012, by the State of Tennessee, through the Tennessee Department of Environment and Conservation (TDEC). Tennessee's October 12, 2012, draft SIP revision includes changes to the maintenance plan for the Knox County 1-hour ozone area submitted on August 26, 1992, and approved by EPA on September 27, 1993, and a subsequent SIP revision approved by EPA on August 5, 1997. The Knox County 1-hour ozone area was comprised of Knox County in its entirety. The October 12, 2012, draft revision proposes to increase the safety margin allocated to motor vehicle emissions budgets (MVEB) for nitrogen oxides (NOX) and volatile organic compounds (VOC) for Knox County to account for changes in the emissions model and vehicle miles traveled (VMT) projection model. EPA is proposing approval of this draft SIP revision pursuant to section 110 of the Clean Air Act (CAA or Act).
Agency Information Collection Activities; Submission to OMB for Review and Approval; Comment Request
In compliance with the Paperwork Reduction Act (PRA), this document announces that an Information Collection Request (ICR) has been forwarded to the Office of Management and Budget (OMB) for review and approval. This is a request to extend the current approval for the Information Collection Request (ICR) entitled ``Pesticide Data Call-In Program'' and identified as EPA ICR No. 2288.02 and OMB Control No. 2070-0174. The ICR, which is abstracted below, describes the nature of the information collection and its estimated burden and cost, and is available in the docket for additional public review and comment.
Water Quality Standards for the State of Florida's Estuaries, Coastal Waters, and South Florida Inland Flowing Waters
The U.S. Environmental Protection Agency (EPA or Agency) is proposing numeric water quality criteria to protect ecological systems, aquatic life, and human health from nitrogen and phosphorus pollution in estuaries and coastal waters within the State of Florida not covered by EPA-approved State rulemaking, and south Florida inland flowing waters. These proposed criteria apply to Florida waters that are designated as Class I, Class II, or Class III waters and they are intended to protect these designated uses as well as implement for the purposes of the Clean Water Act the State's narrative nutrient provision at Subsection 62-302.530(47)(b), Florida Administrative Code (F.A.C.), which provides that ``[i]n no case shall nutrient concentrations of a body of water be altered so as to cause an imbalance in natural populations of aquatic flora or fauna.''
Water Quality Standards for the State of Florida's Streams and Downstream Protection Values for Lakes: Remanded Provisions
The Environmental Protection Agency (EPA or Agency) is proposing a rule that addresses an order by the U.S. District Court for the Northern District of Florida from February 18, 2012, which remanded to EPA two portions of its numeric water quality standards for nutrients in Florida that were promulgated and published on December 6, 2010. For this proposal, EPA is re-proposing the same numeric nutrient criteria for total nitrogen (TN) and total phosphorus (TP) for Florida streams not covered by EPA-approved State rulemaking, as included in EPA's final rule, with further explanation of how the proposed numeric streams criteria will ensure the protection of the Florida's Class I and III designated uses. EPA is also proposing default approaches available for use when modeling cannot be performed to derive downstream protection values (DPVs) that will ensure the attainment and maintenance of the numeric nutrient criteria that protect Florida's lakes. The default approaches would be applicable to streams that flow into unimpaired lakes, but could also be used for streams that flow into impaired lakes.
