List of Hazardous Air Pollutants, Petition Process, Lesser Quantity Designations, Source Category List

Mon, Dec 19 2005 11:00:00 GMT

EPA is amending the list of hazardous air pollutants (HAP) contained in section 112 of the Clean Air Act (CAA) by removing the compound methyl ethyl ketone (MEK) (2Butanone) (CAS No. 78933). This action is being taken in response to a petition submitted by the Ketones Panel of the American Chemistry Council (formerly the Chemical Manufacturers Association) on behalf of MEK producers and consumers to delete MEK from the HAP list. Petitions to remove a substance from the HAP list are permitted under section 112 of the CAA.

Based on the available information concerning the potential hazards of and projected exposures to MEK, EPA has made a determination pursuant to CAA section 112(b)(3)(C) that there are ``adequate data on the health and environmental effects [of MEK] to determine that emissions, ambient concentrations, bioaccumulation, or deposition of the substance may not reasonably be anticipated to cause adverse effects to human health or adverse environmental effects.''

NESHAP: National Emission Standards for Hazardous Air Pollutants: Standards for Hazardous Air Pollutants for Hazardous

Mon, Dec 19 2005 11:00:00 GMT

EPA is taking direct final action on amendments to the national emissions standards for hazardous air pollutants (NESHAP) for hazardous waste combustors which were issued October 12, 2005, under section 112 of the Clean Air Act. In that rule, we inadvertently included three new or revised bag leak detection system requirements for Phase I sourcesincinerators, cement kilns, and lightweight aggregate kilnsamong implementation requirements taking effect on December 12, 2005, rather than, as intended, after three years when the sources begin complying with the revised emission standards under the NESHAP for hazardous waste combustors. We intended to establish the compliance date for these provisions three years after promulgation October 14, 2008because the provisions establish more stringent requirements for Phase I sources, which cannot readily be complied with on short notice, and because these provisions are inextricably tied to the revised emissions standards. We are issuing the amendments as a

Exemption of Certain Area Sources From Title V Operating Permit Programs

Mon, Dec 19 2005 11:00:00 GMT

The EPA is finalizing permanent exemptions from the title V operating permit program for five categories of nonmajor (area) sources that are subject to national emission standards for hazardous air pollutants (NESHAP). The EPA is making a finding for these categories, consistent with the Clean Air Act requirement for making such exemptions, that compliance with title V permitting requirements is impracticable, infeasible, or unnecessarily burdensome on the source categories. The five source categories are dry cleaners, halogenated solvent degreasers, chrome electroplaters, ethylene oxide (EO) sterilizers and secondary aluminum smelters. The EPA declines to make a finding for a sixth category, area sources subject to the NESHAP for secondary lead smelters. A previous deferral from permitting for this category expired on December 9, 2004, subjecting all such sources to the title V program.

TSCA Inventory Update Reporting Revisions

Mon, Dec 19 2005 11:00:00 GMT

EPA is amending the Toxic Substances Control Act (TSCA) section 8(a) Inventory Update Reporting (IUR) regulations. The IUR currently requires manufacturers (including importers) of certain chemical substances listed on the TSCA Chemical Substances Inventory to report data on chemical manufacturing, processing, and use every 4 years. In this amendment, EPA is extending the reporting cycle, modifying the timing of the submission period, further clarifying the new partial exemption for specific chemicals for which certain IUR data are of low current interest, amending the petroleum refinery process streams partial exemption, amending the list of consumer and commercial product categories, revising the manner in which production volume would be reported, restricting reporting of processing and use information to domestic processing and use activities only, clarifying the polymer exemption definition, and removing a provision regarding the confidentiality of production volume within specified ranges

NESHAP: National Emission Standards for Hazardous Air Pollutants: Standards for Hazardous Air Pollutants for Hazardous

Mon, Dec 19 2005 11:00:00 GMT

EPA is proposing amendments to the national emissions standards for hazardous air pollutants (NESHAP) for hazardous waste combustors which were issued October 12, 2005, under section 112 of the Clean Air Act. In that rule, we inadvertently included three new or revised bag leak detection system requirements for Phase I sources incinerators, cement kilns, and lightweight aggregate kilnsamong implementation requirements taking effect on December 12, 2005, rather than, as intended, after three years when the sources begin complying with the revised emission standards under the NESHAP for hazardous waste combustors. We intended to establish the compliance date for these provisions three years after promulgationOctober 14, 2008 because the provisions establish more stringent requirements for Phase I sources, which cannot readily be complied with on short notice, and because these provisions are inextricably tied to the revised emissions standards.

Standards of Performance for New Stationary Sources and Emission Guidelines for Existing Sources: Large Municipal

Mon, Dec 19 2005 11:00:00 GMT

On December 19, 1995, EPA adopted new source performance standards (NSPS) and emission guidelines for large municipal waste combustion (MWC) units. The NSPS and emission guidelines were fully implemented by December 2000. Section 129 of the Clean Air Act (CAA) requires EPA to review, and if appropriate, revise the NSPS and emission guidelines every 5 years. In this action, EPA is proposing to revise the emission limits in the NSPS and emission guidelines to reflect the levels of performance actually achieved by the emission controls installed to meet the emission limits set forth in the December 19, 1995, NSPS and emission guidelines.

The MWC NSPS and emission guidelines apply to the combustion of nonhazardous municipal solid waste. Hazardous waste combustors (incinerators) are addressed by CAA section 112 standards.

Finding of Substantial Inadequacy of Implementation Plan; Call for Missouri State Implementation Plan Revision

Mon, Dec 19 2005 11:00:00 GMT

Pursuant to our authority in the Clean Air Act to call for plan revisions, EPA is proposing to find that the Missouri State Implementation Plan for lead is substantially inadequate to attain or maintain the National Ambient Air Quality Standard for lead in the portion of Jefferson County within the city limits of Herculaneum, Missouri. The specific State Implementation Plan deficiencies, which form the basis for this proposed finding, are described below. If EPA finalizes this proposed finding of substantial inadequacy, Missouri will be required to revise its State Implementation Plan to correct these deficiencies by a date which will be specified in the final rule. If the state fails to submit a revised State Implementation Plan by the deadline, it will be subject to sanctions under the provisions of the Clean Air Act.

Idaho: Incorporation by Reference of Approved State Hazardous Waste Management Program

Mon, Dec 19 2005 11:00:00 GMT

The Resource Conservation and Recovery Act, as amended, 42 U.S.C. 6901 to 6992k (RCRA), allows EPA to authorize State hazardous waste management programs if EPA finds that such programs are equivalent to and consistent with the Federal program and provide adequate enforcement of compliance. Title 40 of the Code of Federal Regulations (CFR) part 272 is used by EPA to codify its decision to authorize individual State programs and incorporates by reference those provisions of the State statutes and regulations that are subject to EPA's inspection and enforcement authorities as authorized provisions of the State's program. This rule proposes to revise the codification of the Idaho authorized program at 40 CFR part 272, subpart N.

Agency Information Collection Activities; Submission to OMB for Review and Approval; Comment Request; Used Oil

In compliance with the Paperwork Reduction Act (44 U.S.C. 3501 et seq.), 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 renew an existing approved collection. This ICR is scheduled to expire on December 31, 2005. Under OMB regulations, the Agency may continue to conduct or sponsor the collection of information while this submission is pending at OMB. This ICR describes the nature of the information collection and its estimated burden and cost.
