Approval and Promulgation of Air Quality Implementation Plans; Connecticut; Reasonably Available Control Technology for the 1997 8-Hour Ozone Standard
EPA is proposing approval of State Implementation Plan revisions submitted by the State of Connecticut. These SIP revisions consist of a demonstration that Connecticut meets the requirements of reasonably available control technology for oxides of nitrogen and volatile organic compounds set forth by the Clean Air Act with respect to the 1997 8-hour ozone standard. Additionally, we are proposing approval of three single source orders. This action is being taken in accordance with the Clean Air Act.
Revision to the Washington State Implementation Plan; Tacoma-Pierce County Nonattainment Area
EPA is proposing to approve a State Implementation Plan (SIP) revision submitted by the Washington Department of Ecology (Ecology) dated November 28, 2012. This SIP revision consists of two elements proposed for EPA approval. First, EPA is proposing to approve the ``2008 Baseline Emissions Inventory and Documentation'' included as Appendix A to the SIP revision. The emissions inventory was submitted to meet Clean Air Act (CAA) requirements related to the Tacoma-Pierce County nonattainment area for the 2006 fine particulate matter (PM2.5) National Ambient Air Quality Standard (NAAQS). Second, EPA is proposing to approve updated rules submitted by Ecology on behalf of the Puget Sound Clean Air Agency (PSCAA), contained in Appendix B, ``SIP Strengthening Rules.'' The updated PSCAA rules help implement the recommendations of the Tacoma-Pierce County Clean Air Task Force, an advisory committee of community leaders, citizen representatives, public health advocates, and other affected parties, formed to develop PM2.5 reduction strategies.
Notice of Intent To Suspend Certain Pesticide Registrations
This notice, pursuant to the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA), publishes two notices of intent to suspend issued by EPA. Each Notice of Intent to Suspend was issued following the Agency's issuance of a Data Call-In notice (DCI), which required the registrants of the affected pesticide products containing a certain pesticide active ingredient to take appropriate steps to secure certain data, and following the registrants' failure to submit these data or to take other appropriate steps to secure the required data. The subject data were determined to be required to maintain in effect the existing registrations of the affected products. Failure to comply with the data requirements of a DCI is a basis for suspension of the affected registrations under FIFRA.
Approval and Promulgation of Implementation Plans; South Carolina: New Source Review-Prevention of Significant Deterioration
EPA is proposing to approve changes to the South Carolina State Implementation Plan (SIP) submitted by the South Carolina Department of Health and Environmental Control (SC DHEC) to EPA in five separate SIP submittals dated May 1, 2012, July 18, 2011, February 16, 2011, December 23, 2009, and December 4, 2008. The SIP revisions make changes to South Carolina's New Source Review (NSR) Prevention of Significant Deterioration (PSD) program to adopt federal PSD requirements regarding fine particulate matter (PM2.5) and changes to the State's provisions related to the national ambient air quality standards (NAAQS) and volatile organic compounds (VOC). EPA is proposing to approve portions of the submittals as revisions to South Carolina's SIP because the Agency has preliminarily determined that they are consistent with section 110 of the Clean Air Act (CAA or Act) and EPA regulations regarding NSR permitting.
Epoxy Polymer; Exemption From the Requirement of a Tolerance
This regulation establishes an exemption from the requirement of a tolerance for residues of polymers of one or more diglycidyl ethers of bisphenol A, resorcinol, glycerol, cyclohexanedimethanol, neopentyl glycol, and polyethylene glycol, with one or more of the following: Polyoxypropylene diamine, polyoxypropylene triamine, N- aminoethyl-piperazine, trimethyl-1,6-hexanediamine isophorone diamine, N,N-dimethyl-1,3-diaminopropane, nadic methyl anhydride, 1,2- cyclohexane-dicarboxylic anhydride and 1,2,3,6-tetrahydrophthalic anhydride; also referred to as epoxy polymer, when used as an inert ingredient in a pesticide chemical formulation. Syngenta Crop Protection, LLC submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of polymers of one or more of the epoxy polymers.
Proposed Significant New Use Rule on Certain Chemical Substances
EPA is proposing significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for four chemical substances which were the subject of premanufacture notices (PMNs). This action would require persons who intend to manufacture, import, or process any of the chemical substances for an activity that is designated as a significant new use by this proposed rule to notify EPA at least 90 days before commencing that activity. The required notification would provide EPA with the opportunity to evaluate the intended use and, if necessary, to prohibit or limit the activity before it occurs.
