40 CFR 63.8390 - What parts of my plant does this subpart cover?

This action provides notice that on March 28, 2013, the Acting EPA Administrator, Bob Perciasepe, signed a letter denying a petition for reconsideration of the final rule published in the Federal Register on September 19, 2012. The rule established new emission limits for hard and decorative chromium electroplating and chromium anodizing tanks, and steel pickling—HCl process facilities and hydrochloric acid regeneration plants.

On April 14, 2010, EPA published a direct final rule approving delegations of authority for Louisiana. There was an error in the amendatory language which resulted in errors in the codification of the delegated Federal authorities for Kentucky and Louisiana. This action corrects the errors.

On July 18, 2012, the EPA proposed amendments to the National Emission Standards for Hazardous Air Pollutants for the Portland Cement Manufacturing Industry and the Standards of Performance for Portland Cement Plants. This final action amends the national emission standards for hazardous air pollutants for the Portland cement industry. The EPA is also promulgating amendments with respect to issues on which it granted reconsideration on May 17, 2011. In addition, the EPA is amending the new source performance standard for particulate matter. These amendments promote flexibility, reduce costs, ease compliance and preserve health benefits. The amendments also address the remand of the national emission standards for hazardous air pollutants for the Portland cement industry by the United States Court of Appeals for the District of Columbia Circuit on December 9, 2011. Finally, the EPA is setting the date for compliance with the existing source national emission standards for hazardous air pollutants to be September 9, 2015.

In this action, the EPA is taking final action on reconsideration of certain issues related to the emission standards to control hazardous air pollutants from new and existing industrial, commercial and institutional boilers at area sources which were issued under section 112 of the Clean Air Act. As part of this action, the EPA is amending certain compliance dates for the standard and making technical corrections to the final rule to clarify definitions, references, applicability and compliance issues raised by petitioners and other stakeholders affected by the rule. The EPA today is taking final action on the proposed reconsideration.

In this action the EPA is taking final action on its reconsideration of certain issues in the emission standards for the control of hazardous air pollutants from new and existing industrial, commercial, and institutional boilers and process heaters at major sources of hazardous air pollutants, which were issued under section 112 of the Clean Air Act. As part of this action, the EPA is making technical corrections to the final rule to clarify definitions, references, applicability and compliance issues raised by petitioners and other stakeholders affected by this rule. On March 21, 2011, the EPA promulgated national emission standards for this source category. On that same day, the EPA also published a notice announcing its intent to reconsider certain provisions of the final rule. Following these actions, the Administrator received several petitions for reconsideration. After consideration of the petitions received, on December 23, 2011, the EPA proposed revisions to certain provisions of the March 21, 2011, final rule, and requested public comment on several provisions of the final rule. The EPA is now taking final action on the proposed reconsideration.

The EPA is finalizing amendments to the national emission standards for hazardous air pollutants for stationary reciprocating internal combustion engines. The final amendments include alternative testing options for certain large spark ignition (generally natural gas-fueled) stationary reciprocating internal combustion engines, management practices for a subset of existing spark ignition stationary reciprocating internal combustion engines in sparsely populated areas and alternative monitoring and compliance options for the same engines in populated areas. The EPA is establishing management practices for existing compression ignition engines on offshore vessels. The EPA is also finalizing limits on the hours that stationary emergency engines may be used for emergency demand response and establishing fuel and reporting requirements for certain emergency engines used for emergency demand response. The final amendments also correct minor technical or editing errors in the current regulations for stationary reciprocating internal combustion engines.

Under the Clean Air Act (“CAA”) and Federal regulations promulgated there under, the New Hampshire Department of Environmental Services (“NH DES”) submitted a request for approval to implement and enforce the readopted and re-codified “Env-Sw 2100: Management and Control of Asbestos Disposal Sites Not Operated after July 9, 1981,” and the amended “Env-A 1801-1807.01: Asbestos Management and Control,” (amended Asbestos Management Rules) in place of the National Emission Standard for Asbestos (“Asbestos NESHAP”). EPA has reviewed this request and has determined that the amended Asbestos Management Rules satisfy the requirements necessary for approval. Thus, EPA is hereby granting NH DES the authority to implement and enforce the amended Asbestos Management Rules in place of the Asbestos NESHAP. This approval makes NH DES's amended Asbestos Management Rules federally enforceable.

On January 30, 2012, the EPA proposed revisions to several provisions of the final National Emission Standards for Hazardous Air Pollutants for Chemical Manufacturing Area Sources. The proposed revisions were made, in part, in response to a petition for reconsideration received by the Administrator following the promulgation of the October 29, 2009, final rule (“2009 final rule”). In this action, the EPA is finalizing those amendments, lifting the stay of the title V permit requirement issued on March 14, 2011, and lifting the stay of the final rule issued on October 25, 2012. In addition, this final action includes revisions to the EPA's approach for addressing malfunctions and standards applicable during startup and shutdown periods. This final action also includes amendments and technical corrections to the final rule to clarify applicability and compliance issues raised by stakeholders subject to the 2009 final rule. The revisions to the final rule do not reduce the level of environmental protection or emissions control on sources regulated by this rule but provide flexibility and clarity to improve implementation. This action also extends the compliance date for existing sources and the EPA's final response to all issues raised in the petition for reconsideration.

On February 16, 2012, pursuant to sections 111 and 112 of the Clean Air Act (CAA), the EPA published the final rules titled “National Emission Standards for Hazardous Air Pollutants from Coal- and Oil-fired Electric Utility Steam Generating Units and Standards of Performance for Fossil-Fuel-Fired Electric Utility, Industrial-Commercial-Institutional, and Small Industrial-Commercial-Institutional Steam Generating Units.” The National Emission Standards for Hazardous Air Pollutants (NESHAP) rule issued pursuant to CAA section 112 is referred to as the Mercury and Air Toxics Standards (MATS), and the New Source Performance Standards rule issued pursuant to CAA section 111 is referred to as the Utility NSPS. The Administrator received petitions for reconsideration of certain aspects of MATS and the Utility NSPS. In this notice, the EPA is announcing reconsideration of certain new source standards for MATS, the requirements applicable during periods of startup and shutdown for MATS, the startup and shutdown provisions related to the particulate matter (PM) standard in the Utility NSPS, and certain revisions to the definitional and monitoring provisions of the Utility NSPS. We are also proposing certain technical corrections to both MATS and the Utility NSPS. We seek comment only on the aspects of the final MATS and Utility NSPS rules specifically identified in this notice. We are not opening for reconsideration any other provisions of MATS or the Utility NSPS at this time.

On January 30, 2012, the EPA published in the Federal Register a proposed rule reconsidering certain provisions in the final National Emission Standards for Hazardous Air Pollutants for Chemical Manufacturing Area Sources (CMAS) that was promulgated on October 29, 2009. The compliance date for the final CMAS rule is October 29, 2012. However, the EPA is still in the process of finalizing the reconsideration action. For this reason, a short stay of the final CMAS rule pending completion of the reconsideration action is warranted. Pursuant to the Clean Air Act, the EPA is staying until December 24, 2012 the final CMAS rule.

This action finalizes the residual risk and technology review conducted for the following source categories regulated under two national emission standards for hazardous air pollutants (NESHAP): hard and decorative chromium electroplating and chromium anodizing tanks, and steel pickling—HCl process facilities and hydrochloric acid regeneration plants. On October 21, 2010, EPA proposed amendments to these NESHAP under section 112(d)(6) and (f)(2) of the Clean Air Act. On February 8, 2012, EPA published a supplemental proposal with new analyses and results. For hard and decorative chromium electroplating and chromium anodizing tanks these final amendments addressing Clean Air Act (CAA) sections 112(d)(6) and (f)(2) include revisions to the emissions limits for total chromium; addition of housekeeping requirements to minimize fugitive emissions; and a requirement to phase-out the use of perfluorooctane sulfonic acid (PFOS) based fume suppressants. These requirements will provide greater protection for public health and the environment by reducing emissions of hexavalent chromium (a known human carcinogen). In addition, as part of the October 2010 proposal, we proposed certain actions pursuant to CAA section 112(d)(2) and (3) for hard and decorative chromium electroplating and chromium anodizing tanks. For these sources, we are modifying and adding testing and monitoring, recordkeeping, and reporting requirements; and revisions to the regulatory provisions related to emissions during periods of malfunction. For steel pickling hydrochloric acid regeneration plants, we are finalizing our proposal to remove the alternative compliance method because we believe it is inconsistent with the requirements of CAA section 112(d)(2) and (3). This amendment will achieve reductions in chlorine emissions. Additionally, we are adding provisions to the Steel Pickling Facilities NESHAP requiring that the emission limits of the rule apply at all times, including during periods of startup, shutdown and malfunction.

This action finalizes the residual risk and technology review conducted for the pulp and paper industry source category regulated under national emission standards for hazardous air pollutants. The EPA is required to conduct residual risk and technology reviews under the Clean Air Act. This action finalizes amendments to the national emission standards for hazardous air pollutants that include a requirement for 5-year repeat emissions testing for selected process equipment; revisions to provisions addressing periods of startup, shutdown and malfunction; a requirement for electronic reporting; additional test methods for measuring methanol emissions; and technical and editorial changes. The amendments are expected to ensure that control systems are properly maintained over time, ensure continuous compliance with standards and improve data accessibility; we estimate facilities nationwide will spend $2.1 million per year to comply.

This action finalizes the review of new source performance standards for the listed oil and natural gas source category. In this action the EPA revised the new source performance standards for volatile organic compounds from leaking components at onshore natural gas processing plants and new source performance standards for sulfur dioxide emissions from natural gas processing plants. The EPA also established standards for certain oil and gas operations not covered by the existing standards. In addition to the operations covered by the existing standards, the newly established standards will regulate volatile organic compound emissions from gas wells, centrifugal compressors, reciprocating compressors, pneumatic controllers and storage vessels. This action also finalizes the residual risk and technology review for the Oil and Natural Gas Production source category and the Natural Gas Transmission and Storage source category. This action includes revisions to the existing leak detection and repair requirements. In addition, the EPA has established in this action emission limits reflecting maximum achievable control technology for certain currently uncontrolled emission sources in these source categories. This action also includes modification and addition of testing and monitoring and related notification, recordkeeping and reporting requirements, as well as other minor technical revisions to the national emission standards for hazardous air pollutants. This action finalizes revisions to the regulatory provisions related to emissions during periods of startup, shutdown and malfunction.

This action stays the effectiveness of national new source emission standards for hazardous air pollutants from coal- and oil-fired electric utility steam generating units issued pursuant to Clean Air Act section 112 that were published in the Federal Register on February 16, 2012 (77 FR 9304).

EPA is taking direct final action to delegate the authority to implement and enforce specific National Emission Standards for Hazardous Air Pollutants (NESHAP) to the Gila River Indian Community Department of Environmental Quality (GRIC) in Arizona. The preamble outlines the process that GRIC will use to receive delegation of any future NESHAP, and identifies the NESHAP categories to be delegated by today's action. EPA has reviewed GRIC's request for delegation and has found that this request satisfies all of the requirements necessary to qualify for approval. Thus, EPA is hereby granting GRIC the authority to implement and enforce the unchanged NESHAP categories listed in this rule.

This action provides notice that on March 28, 2013, the Acting EPA Administrator, Bob Perciasepe, signed a letter denying a petition for reconsideration of the final rule published in the Federal Register on September 19, 2012. The rule established new emission limits for hard and decorative chromium electroplating and chromium anodizing tanks, and steel pickling—HCl process facilities and hydrochloric acid regeneration plants.

This action proposes chromium and particulate matter (for metals) standards for wool fiberglass gas-fired glass-melting furnaces at area sources and adds these sources to the category list in the Urban Air Toxics Strategy. It also proposes amendments to the existing major source rules for Mineral Wool and Wool Fiberglass, supplementing the rule proposed on November 25, 2011. The proposed area source standards for the gas-fired glass-melting furnaces used to make wool fiberglass would increase the level of environmental protection.

On April 14, 2010, EPA published a direct final rule approving delegations of authority for Louisiana. There was an error in the amendatory language which resulted in errors in the codification of the delegated Federal authorities for Kentucky and Louisiana. This action corrects the errors.

This notice announces that EPA will review three regulatory actions pursuant to section 610 of the Regulatory Flexibility Act. Those three actions are: Heavy-Duty Engine and Vehicle Standards and Highway Diesel Fuel Sulfur Control Requirements (Heavy-Duty 610 Review); NESHAP: Reinforced Plastic Composites Production (Plastics 610 Review); and NPDES Permit Regulation and Effluent Limitations Guidelines Standards for CAFOs (CAFO 610 Review). As part of this review, EPA will consider and solicit comments on the following factors: The continued need for the rules; the nature of complaints or comments received concerning the rules; the complexity of the rules; the extent to which the rules overlap, duplicate, or conflict with other Federal, State, or local government rules; and the degree to which the technology, economic conditions or other factors have changed in areas affected by the rules.

On January 30, 2012, the EPA published in the Federal Register a proposed rule reconsidering certain provisions in the final National Emission Standards for Hazardous Air Pollutants for Chemical Manufacturing Area Sources (CMAS) that was promulgated on October 29, 2009. The compliance date for the final CMAS rule is October 29, 2012. However, the EPA is still in the process of finalizing the reconsideration action. For this reason, a short stay of the final CMAS rule pending completion of the reconsideration action is warranted. Pursuant to the Clean Air Act, the EPA is staying until December 24, 2012 the final CMAS rule.

The EPA is reopening the public comment period for the proposed amendments to the National Emission Standards for Hazardous Air Pollutants for Stationary Reciprocating Internal Combustion Engines to solicit comment on specific issues raised during the initial public comment period regarding existing engines on offshore vessels.

This action finalizes the residual risk and technology review conducted for the following source categories regulated under two national emission standards for hazardous air pollutants (NESHAP): hard and decorative chromium electroplating and chromium anodizing tanks, and steel pickling—HCl process facilities and hydrochloric acid regeneration plants. On October 21, 2010, EPA proposed amendments to these NESHAP under section 112(d)(6) and (f)(2) of the Clean Air Act. On February 8, 2012, EPA published a supplemental proposal with new analyses and results. For hard and decorative chromium electroplating and chromium anodizing tanks these final amendments addressing Clean Air Act (CAA) sections 112(d)(6) and (f)(2) include revisions to the emissions limits for total chromium; addition of housekeeping requirements to minimize fugitive emissions; and a requirement to phase-out the use of perfluorooctane sulfonic acid (PFOS) based fume suppressants. These requirements will provide greater protection for public health and the environment by reducing emissions of hexavalent chromium (a known human carcinogen). In addition, as part of the October 2010 proposal, we proposed certain actions pursuant to CAA section 112(d)(2) and (3) for hard and decorative chromium electroplating and chromium anodizing tanks. For these sources, we are modifying and adding testing and monitoring, recordkeeping, and reporting requirements; and revisions to the regulatory provisions related to emissions during periods of malfunction. For steel pickling hydrochloric acid regeneration plants, we are finalizing our proposal to remove the alternative compliance method because we believe it is inconsistent with the requirements of CAA section 112(d)(2) and (3). This amendment will achieve reductions in chlorine emissions. Additionally, we are adding provisions to the Steel Pickling Facilities NESHAP requiring that the emission limits of the rule apply at all times, including during periods of startup, shutdown and malfunction.
