Notice of Availability of the Recommended Toxicity Equivalence Factors (TEFs) for Human Health Risk Assessments of 2,3,7,8-Tetrachlorodibenzo-p-dioxin and Dioxin-Like Compounds
The U.S. Environmental Protection Agency (EPA) is announcing the availability of the final ``Recommended Toxicity Equivalence Factors (TEFs) for Human Health Risk Assessments of 2,3,7,8- Tetrachlorodibenzo-p-dioxin and Dioxin-Like Compounds'' (EPA/100/R-10/ 005). The purpose of this document is to assist EPA scientists in using the toxicity equivalence methodology to assess health risks from dioxins and dioxin-like compounds, as well as inform EPA decision makers, other agencies, and the public about this methodology. This guidance document summarizes the toxicity equivalence methodology, provides background information and assumptions on how the methodology has evolved, and recommends an approach for health risk assessors to use to apply the methodology. EPA's Risk Assessment Forum (RAF) oversaw the development of this document. Input was obtained from scientists throughout the Agency, from interested members of the public, and from external experts from a range of scientific disciplines via a contractor-led peer review.
Notice of Nationwide Waiver of Section 1605 (Buy American Requirement) of the American Recovery and Reinvestment Act of 2009 (ARRA) for the Use of Small Horsepower Vertical Hollow Shaft Electric Motors (Less Than 40 Horsepower) for Projects Financed Through the Clean or Drinking Water State Revolving Funds Using Assistance Provided Under ARRA
The EPA is hereby granting a nationwide waiver of the Buy American requirements of ARRA Section 1605 under the authority of Section 1605(b)(2) [manufactured goods are not produced in the United States in sufficient and reasonably available quantities and of a satisfactory quality] for small-horsepower (HP) vertical hollow shaft (VHS) electric motors (less than 40 HP). This nationwide waiver applies to the use of the specified products and is applicable only for their purchase and installation for one-year subsequent to the effective date of the waiver. Based upon information gathered from multiple waiver request submittals and further research by its contractor, EPA has determined that domestically manufactured small-HP VHS electric motors (less than 40 HP) are not reasonably available. The Assistant Administrator for the Office of Water is making this determination based on the review and recommendations of the Office of Ground Water and Drinking Water and the Office of Wastewater Management. The Assistant Administrator of the Office of Administration and Resources Management has concurred on this decision to make an exception to Section 1605 of ARRA. This action permits the nationwide purchase and installation of non-domestic VHS electric motors less than 40 HP up to one-year subsequent to the effective date of the waiver. EPA reserves the right to withdraw or amend this nationwide waiver based on new developments or changes in the domestic manufacturing capacity for these items.
Disapproval and Promulgation of Air Quality Implementation Plans; Montana; Revisions to the Administrative Rules of Montana-Air Quality, Subchapter 7, Subchapter 16 and Subchapter 17
EPA is proposing to disapprove portions of revisions and new rules as submitted by the State of Montana on October 16, 2006 and November 1, 2006. Montana adopted these rules on December 2, 2005 and March 23, 2006 and these rules became State-effective on January 1, 2006. These revisions and new rules do not meet the requirements of the Clean Air Act and EPA's Minor New Source Review (NSR) regulations. EPA has concluded that none of the identified elements for the submitted revisions and new rules are severable from each other. The intended effect of this action is to propose to disapprove these rules as they are inconsistent with the Clean Air Act. This action is being taken under section 110 of the Clean Air Act.
Approval and Promulgation of Implementation Plans; Connecticut: Prevention of Significant Deterioration; Greenhouse Gas Permitting Authority and Tailoring Rule Revision
EPA is proposing to approve a draft revision to the State Implementation Plan (SIP), submitted by Connecticut on December 9, 2010, for parallel processing. The proposed SIP revision makes two changes impacting Connecticut's New Source Review (NSR) Prevention of Significant Deterioration (PSD) program. First, the proposed revision provides the State of Connecticut with authority to regulate greenhouse gases (GHGs) under its PSD program. Second, the proposed SIP revision establishes appropriate emission thresholds for determining which stationary sources and modification projects become subject to Connecticut's PSD permitting requirements for their GHG emissions. The first component of the proposed revision is necessary because the State of Connecticut is required to apply its PSD program to GHG-emitting sources, and unless it does so (or unless EPA promulgates a federal implementation plan (FIP) to do so), such sources will be unable to receive preconstruction permits and therefore may not be able to construct or modify. The second component is necessary because without it, on January 2, 2011, PSD requirements would apply at the 100 or 250 tons per year (tpy) levels provided under the Clean Air Act (CAA or Act), which would overwhelm Connecticut's permitting resources.
Guidelines for Awarding Clean Water Act Section 319 Base Grants to Indian Tribes
This final rule provides national guidelines for the award of base grants under the Clean Water Act (CWA) section 319(h) nonpoint source (NPS) grants program to Indian tribes in FY 2011 (and subsequent years). In addition, the rule includes a few new administrative changes to clarify the guidelines and make them more user-friendly. The new administrative changes for base grant submissions are: That each EPA Region will now establish its own individual timeframe for tribes to submit application materials for section 319 base grants; the inclusion of information on how to calculate the cost-share/match; and the availability of facsimile submission for section 319 base grant application materials when the tribe coordinates with the appropriate EPA Regional coordinator in advance of the section 319 base grant application deadline.
Finding of Substantial Inadequacy of Implementation Plan; Call for Kansas Section 110 State Implementation Plan for Interstate Transport for the 1997 National Ambient Air Quality Standards for Ozone
Pursuant to our authority under the Clean Air Act (CAA), EPA is proposing to find that the Kansas State Implementation Plan (SIP) is substantially inadequate to satisfy the CAA requirement to address Kansas' significant contribution to downwind nonattainment or interference with maintenance in another State with respect to the 1997 National Ambient Air Quality Standards (NAAQS) for ozone. The specific State Implementation Plan deficiencies that EPA has identified are described in this proposal and in the proposed Federal Implementation Plan To Reduce Interstate Transport of Fine Particulate Matter and Ozone. If EPA finalizes this proposed finding of substantial inadequacy, Kansas will be required to revise its SIP to correct these deficiencies no later than 12 months following the date of signature of the final finding of substantial inadequacy.
