40 CFR Part 63, Subpart JJ - National Emission Standards for Wood Furniture Manufacturing Operations

The Environmental Protection Agency (EPA) published a final rule in the Federal Register on October 26, 2015, titled NESHAP for Brick and Structural Clay Products Manufacturing; and NESHAP for Clay Ceramics Manufacturing. These amendments make two technical corrections to the published regulation.

This action finalizes the residual risk and technology review conducted for the Petroleum Refinery source categories regulated under national emission standards for hazardous air pollutants (NESHAP) Refinery MACT 1 and Refinery MACT 2. It also includes revisions to the Refinery MACT 1 and MACT 2 rules in accordance with provisions regarding establishment of MACT standards. This action also finalizes technical corrections and clarifications for the new source performance standards (NSPS) for petroleum refineries to improve consistency and clarity and address issues related to a 2008 industry petition for reconsideration. Implementation of this final rule will result in projected reductions of 5,200 tons per year (tpy) of hazardous air pollutants (HAP) which will reduce cancer risk and chronic health effects.

This action sets forth the Environmental Protection Agency's (EPA's) final decision on the issues for which it granted reconsideration on January 21, 2015, that pertain to certain aspects of the January 31, 2013, final amendments to the “National Emission Standards for Hazardous Air Pollutants for Major Sources: Industrial, Commercial, and Institutional Boilers and Process Heaters” (Boiler MACT). The EPA is retaining a minimum carbon monoxide (CO) limit of 130 parts per million (ppm) and the particulate matter (PM) continuous parameter monitoring system (CPMS) requirements, consistent with the January 2013 final rule. The EPA is making minor changes to the proposed definitions of startup and shutdown and work practices during these periods, based on public comments received. Among other things, this final action addresses a number of technical corrections and clarifications of the rule. These corrections will clarify and improve the implementation of the January 2013 final Boiler MACT, but do not have any effect on the environmental, energy, or economic impacts associated with the proposed action. This action also includes our final decision to deny the requests for reconsideration with respect to all issues raised in the petitions for reconsideration of the final Boiler MACT for which we did not grant reconsideration.

The Environmental Protection Agency (EPA) is finalizing national emission standards for hazardous air pollutants (NESHAP) for Brick and Structural Clay Products (BSCP) Manufacturing and NESHAP for Clay Ceramics Manufacturing. All major sources in these categories must meet maximum achievable control technology (MACT) standards for mercury (Hg), non-mercury (non-Hg) metal hazardous air pollutants (HAP) (or particulate matter (PM) surrogate) and dioxins/furans (Clay Ceramics only); health-based standards for acid gas HAP; and work practice standards, where applicable. The final rule, which has been informed by input from industry (including small businesses), environmental groups, and other stakeholders, protects air quality and promotes public health by reducing emissions of HAP listed in section 112 of the Clean Air Act (CAA).

This action finalizes the residual risk and technology review (RTR) conducted for the Primary Aluminum Production source category regulated under national emission standards for hazardous air pollutants (NESHAP). In addition, we are taking final action regarding new and revised emission standards for various hazardous air pollutants (HAP) emitted by this source category based on the RTR, newly obtained emissions test data, and comments we received in response to the 2011 proposal and 2014 supplemental proposal. These final amendments include technology-based standards and work practice standards reflecting performance of maximum achievable control technology (MACT), and related monitoring, reporting, and testing requirements, for several previously unregulated HAP from various emissions sources. Furthermore, based on our risk review, we are finalizing new and revised emission standards for certain HAP emissions from potlines using the Soderberg technology to address risk. We are also adding a requirement for electronic reporting of compliance data, eliminating the exemptions for periods of startup, shutdown, and malfunctions (SSM), and not adopting the affirmative defense provisions proposed in 2011, consistent with a recent court decision vacating the affirmative defense provisions. This action will provide improved environmental protection regarding potential emissions of HAP emissions from primary aluminum reduction facilities.

This action finalizes the residual risk and technology review (RTR), and the rule review, we conducted for the Secondary Aluminum Production source category regulated under national emission standards for hazardous air pollutants (NESHAP). In this action, we are finalizing several amendments to the NESHAP based on the rule review. These final amendments include a requirement to report performance testing through the Electronic Reporting Tool (ERT); provisions allowing owners and operators to change furnace classifications; requirements to account for unmeasured emissions during compliance testing for group 1 furnaces that do not have add-on control devices; alternative compliance options for the operating and monitoring requirements for sweat furnaces; compliance provisions for hydrogen fluoride; provisions addressing emissions during periods of startup, shutdown, and malfunction (SSM); and other corrections and clarifications to the applicability, definitions, operating, monitoring and performance testing requirements. These amendments will improve the monitoring, compliance and implementation of the rule.

The Environmental Protection Agency (EPA) published a final rule in the Federal Register on July 27, 2015, titled National Emission Standards for Hazardous Air Pollutants for the Portland Cement Manufacturing Industry and Standards of Performance for Portland Cement Plants. This final rule makes technical corrections and clarifications to the regulations published in that final rule. The rule also includes a provision describing performance testing requirements when a source demonstrates compliance with the hydrochloric acid (HCl) emissions standard using a continuous emissions monitoring system (CEMS) for sulfur dioxide measurement and reporting.

This action finalizes the residual risk and technology review conducted for the Phosphoric Acid Manufacturing and Phosphate Fertilizer Production source categories regulated under national emission standards for hazardous air pollutants (NESHAP). In addition, this action finalizes an 8-year review of the current new source performance standards (NSPS) for five source categories. We are also taking final action addressing Clean Air Act (CAA) provisions related to emission standards for hazardous air pollutants, review and revision of emission standards, and work practice standards. The final amendments to the Phosphoric Acid Manufacturing NESHAP include: Numeric emission limits for previously unregulated mercury (Hg) and total fluoride emissions from calciners; work practice standards for hydrogen fluoride (HF) emissions from previously unregulated gypsum dewatering stacks and cooling ponds; clarifications to the applicability and monitoring requirements to accommodate process equipment and technology changes; removal of the exemptions for startup, shutdown, and malfunction (SSM); adoption of work practice standards for periods of startup and shutdown; and revised recordkeeping and reporting requirements for periods of SSM. The final amendments to the Phosphate Fertilizer Production NESHAP include: Clarifications to the applicability and monitoring requirements to accommodate process equipment and technology changes; removal of the exemptions for SSM; adoption of work practice standards for periods of startup and shutdown; and revised recordkeeping and reporting requirements for periods of SSM. The revised NESHAP for Phosphoric Acid Manufacturing facilities will mitigate future increases of Hg emissions from phosphate rock calciners by requiring pollution prevention measures. Further, based on the 8-year review of the current NSPS for these source categories, the EPA determined that no revisions to the numeric emission limits in those rules are warranted.

This action finalizes the residual risk and technology reviews (RTR) conducted for the Mineral Wool Production and Wool Fiberglass Manufacturing source categories regulated under national emission standards for hazardous air pollutants (NESHAP). Under this action, we are establishing pollutant-specific emissions limits for hazardous air pollutants (HAP) that were previously regulated (under a surrogate) and for HAP that were previously unregulated. This action finalizes first-time generally available control technologies (GACT) standards for gas-fired glass-melting furnaces at wool fiberglass manufacturing facilities that are area sources. We are also amending regulatory provisions related to emissions during periods of startup, shutdown, and malfunction (SSM); adding requirements for reporting of performance testing through the Electronic Reporting Tool (ERT); and making several minor clarifications and corrections. The revisions in these final rules increase the level of emissions control and environmental protection provided by the Mineral Wool Production and Wool Fiberglass Manufacturing NESHAP.

The Environmental Protection Agency (EPA) published a final rule in the Federal Register on October 26, 2015, titled NESHAP for Brick and Structural Clay Products Manufacturing; and NESHAP for Clay Ceramics Manufacturing. These amendments make two technical corrections to the published regulation.

This action requests information related to hazardous air pollutant (HAP) emissions from sources in the oil and natural gas production and natural gas transmission and storage segments of the oil and natural gas sector. In 2012, the Environmental Protection Agency (EPA) revised the National Emission Standards for Hazardous Air Pollutants (NESHAP) for the Oil and Natural Gas Production Facilities and the Natural Gas Transmission and Storage Facilities major source categories. This action requests additional data and information that was not available at that time. In particular, we are requesting data on storage vessels without potential flash emissions (PFE) and data on HAP emissions from regulated small glycol dehydrators. With regard to the small glycol dehydrators we are particularly interested in data regarding any emissions of HAP other than benzene, toluene, ethylbenzene, and xylene (BTEX), information on available control options for any such HAP and information regarding a potential compliance demonstration issue with respect to the 2012 standards for small glycol dehydration units, as they apply to units with very low emissions.

The Environmental Protection Agency (EPA) is extending the comment period for the proposed rule titled, “Revisions to Test Methods, Performance Specifications, and Testing Regulations for Air Emission Sources,” that was published in the Federal Register on September 8, 2015. The 60-day comment period in the proposed rule is scheduled to end on November 9, 2015. The extended comment period will close on December 9, 2015. The EPA recently added a technical justification to the docket for the revision in the proposed rule regarding Subpart JJJJ of Part 60 (Standards of Performance for Stationary Spark Ignition Internal Combustion Engines). We also added background information to support our reasoning for soliciting comment about Method 7E stratification. Therefore, the EPA is extending the comment period to allow the public additional time to submit comments and supporting information on these and other aspects of the proposed rule.

The Environmental Protection Agency (EPA) is announcing a public hearing for the proposed rule titled, “Revisions to Test Methods, Performance Specifications, and Testing Regulations for Air Emission Sources,” that was published in the Federal Register on September 8, 2015. The hearing will be held in Research Triangle Park, North Carolina. The EPA is proposing technical and editorial corrections and revisions to regulations related to source testing of emissions. The EPA is proposing to make corrections and updates to testing provisions that contain inaccuracies and outdated procedures, and to provide alternatives to existing testing regulations. The revisions will improve the quality of data and provide testers flexibility to use recently-approved alternative procedures. Many of the changes were suggested by testers and other end-users and will not impose new substantive requirements on source owners or operators.
