National Emission Standards for Hazardous Air Pollutants: Ethylene Oxide Commercial Sterilization and Fumigation Operations
In this advance notice of proposed rulemaking (ANPRM), the U.S. Environmental Protection Agency (EPA) is soliciting information that will aid in potential future revisions to the Ethylene Oxide Emission Standards for Sterilization Facilities. The EPA is soliciting information and requesting comment on potential control measures for reducing ethylene oxide (EtO) emissions from commercial sterilization facilities. These control measures include controls for fugitive emissions of EtO, safety measures for the chamber exhaust vents (CEVs), process equipment improvements, and advances in add-on control technologies for point sources. In addition, the EPA is considering, and requesting comment on, how best to assess potential impacts on small businesses. The EPA is also taking comment on the available EtO usage data for individual facilities and on additional data contained in the modeling file that will be used to evaluate the impact of emissions from commercial EtO sterilizers.
Approval and Promulgation of Air Quality Implementation Plans; Delaware; Amendments to the Regulatory Definition of Volatile Organic Compounds
The Environmental Protection Agency (EPA) is approving a state implementation plan (SIP) revision submitted by the State of Delaware. The revisions pertain to amendments made to the definition of volatile organic compound (VOC) in the Delaware Administrative Code to conform with EPA's regulatory definition of VOC. EPA found that certain compounds have negligible photochemical reactivity and, therefore, has exempted them from the regulatory definition of VOC in several rulemaking actions. This revision to the Delaware SIP requested the exemption of eight compounds from the regulatory definition of VOC to match the actions EPA has taken. The revision also requested to remove the recordkeeping, reporting, modeling, and inventory requirements for t-butyl acetate (TBAC). EPA is approving these revisions to update the definition of VOC in the Delaware SIP in accordance with the requirements of the Clean Air Act (CAA).
North Dakota: Incorporation by Reference of State Hazardous Waste Management Program
This rule codifies in the regulations the prior approval of North Dakota's hazardous waste management program and incorporates by reference authorized provisions of the State's statutes and regulations. The Environmental Protection Agency (EPA) uses the regulations entitled, ``Approved State Hazardous Waste Management Programs,'' to provide notice of the authorization status of State programs, and to incorporate by reference those provisions of the State statutes and regulations that are authorized and that EPA will enforce under the Solid Waste Disposal Act, commonly referred to as the Resource Conservation and Recovery Act (RCRA). The EPA previously provided notices and opportunity for comments on the Agency's decisions to authorize the State of North Dakota program and the EPA is not now reopening the decisions, nor requesting comments, on the North Dakota authorization as previously published in the Federal Register documents specified in Section I.C. of this final rule document.
