Approval and Promulgation of Air Quality Implementation Plans; State of Delaware; Regional Haze State Implementation Plan
EPA is proposing to approve a revision to the Delaware State Implementation Plan (SIP) submitted by the State of Delaware through the Delaware Department of Natural Resources and Environmental Control (DNREC) on September 25, 2008 that addresses regional haze for the first implementation period. This revision addresses the requirements of the Clean Air Act (CAA) and EPA's rules that require states to prevent any future, and remedy any existing, anthropogenic impairment of visibility in mandatory Class I areas caused by emissions of air pollutants from numerous sources located over a wide geographic area (also referred to as the ``regional haze program''). States are required to assure reasonable progress toward the national goal of achieving natural visibility conditions in Class I areas. EPA is proposing to determine that the Regional Haze plan submitted by Delaware satisfies the requirements of the CAA. EPA is taking this action pursuant to those provisions of the CAA. EPA is also proposing to approve this revision as meeting the requirements of 110(a)(2)(D)(i)(II) and 110(a)(2)(J), relating to visibility protection for the 1997 8-Hour Ozone National Ambient Air Quality Standard (NAAQS) and the 1997 and 2006 fine particulate matter (PM2.5) NAAQS.

State Program Requirements; Application for Program Revision to the National Pollutant Discharge Elimination System (NPDES) Program; Alaska
EPA approved Alaska's National Pollutant Discharge Elimination System (NPDES) program application on October 31, 2008 pursuant to section 402 of the Clean Water Act (CWA or ``the Act''). The approved State program, called the Alaska Pollutant Discharge Elimination System (APDES), includes an implementation plan that transfers the administration of specific program components from EPA to the Alaska Department of Environmental Conservation (ADEC) in four phases over a three year period from the date of program approval. Phases I-III have been transferred from EPA to ADEC. Transfer of the final phase, Phase IV, is currently scheduled for October 31, 2011. ADEC has made a submission for approval for a one year extension of the transfer of Phase IV of the APDES program, which includes oil and gas, cooling water intakes and dischargers, munitions and all other remaining facilities not previously transferred in Phases I-III. If EPA approves the APDES program revision, Phase IV will transfer to ADEC four years from the date of program approval, or October 31, 2012. Today, EPA is requesting comments on the proposed one year extension and is providing notice of a public hearing and comment period on the proposal. The EPA Region 10 Regional Administrator will either approve or disapprove the APDES program revision after considering all comments received during the public comment period.
Approval and Promulgation of Air Quality Implementation Plans; Indiana
EPA is approving a request submitted by the Indiana Department of Environmental Management (IDEM) on November 24, 2010, to revise the Indiana State Implementation Plan (SIP). The submission revises the Indiana Administrative Code (IAC) by amending and updating the definition of ``References to the Code of Federal Regulations,'' to refer to the 2009 edition. The submission also makes a minor revision to the definition of ``Nonphotochemically reactive hydrocarbons'' or ``negligibly photochemically reactive compounds'' by deleting an outdated Federal Register citation.

Approval and Promulgation of Air Quality Implementation Plans; Massachusetts; Revised Carbon Monoxide Maintenance Plan for Lowell
EPA is approving a State Implementation Plan (SIP) revision submitted by the State of Massachusetts. This SIP submittal contains revisions to the carbon monoxide (CO) maintenance plan for Lowell, Massachusetts. Specifically, Massachusetts has revised the contingency plan portion of the original maintenance plan. The intended effect of this action is to approve this revision to the Lowell CO maintenance plan. This action is being taken in accordance with the Clean Air Act.
Approval and Promulgation of Air Quality Implementation Plans; Virginia; Prevention of Significant Deterioration; Greenhouse Gas Permitting Authority and Tailoring Rule Revision
EPA is approving a State Implementation Plan (SIP) revision submitted by the Virginia Department of Environmental Quality (VADEQ) on October 27, 2010. This revision pertains to EPA's greenhouse gas (GHG) Prevention of Significant Deterioration (PSD) permitting provisions as promulgated on June 3, 2010 in the Tailoring Rule. The SIP revision modifies Virginia's PSD program to establish appropriate emission thresholds for determining which new stationary sources and modifications become subject to Virginia's PSD permitting requirements for their GHG emissions. EPA is approving Virginia's SIP revision because the Agency has determined that this SIP revision is in accordance with the CAA and Federal regulations regarding PSD permitting for GHGs.
Modification of the Significant New Uses of 2-Propen-1-one, 1-(4-morpholinyl)-
EPA is finalizing an amendment to the significant new use rule (SNUR) under the Toxic Substances Control Act (TSCA) for 2-Propen-1- one, 1-(4-morpholinyl)- (CAS No. 5117-12-4). This action requires persons who intend to manufacture, import, or process the chemical substance for a use that is designated as a significant new use by this final rule to notify EPA at least 90 days before commencing that activity. EPA believes that this action is necessary because the chemical substance may be hazardous to human health. The required notification would provide EPA with the opportunity to evaluate the intended use and, if necessary, to prohibit or limit that activity before it occurs.
