40 CFR Part 63, Subpart KK - National Emission Standards for the Printing and Publishing Industry

The Albuquerque-Bernalillo County Air Quality Control Board (ABCAQCB) has submitted updated regulations for receiving delegation of the Environmental Protection Agency (EPA) authority for implementation and enforcement of New Source Performance Standards (NSPS) and National Emission Standards for Hazardous Air Pollutants (NESHAPs) for all sources (both part 70 and non-part 70 sources). The delegation of authority under this action applies only to sources located in Bernalillo County, New Mexico, and does not extend to sources located in Indian Country. EPA is providing notice that it is updating the delegation of certain NSPS to ABCAQCB, and taking direct final action to approve the delegation of certain NESHAPs to ABCAQCB.

The Environmental Protection Agency (EPA) is taking direct final action to amend the National Emission Standards for Hazardous Air Pollutants for Polyvinyl Chloride and Copolymers Production Area Sources. This direct final rule withdraws the total non-vinyl chloride organic hazardous air pollutant (TOHAP) process wastewater emission standards for new and existing polyvinyl chloride and copolymers (PVC) area sources.

The New Mexico Environment Department (NMED) has submitted updated regulations for receiving delegation of the Environmental Protection Agency (EPA) authority for implementation and enforcement of New Source Performance Standards (NSPS) and National Emission Standards for Hazardous Air Pollutants (NESHAPs) for all sources (both part 70 and non-part 70 sources). The delegation of authority under this action does not apply to sources located in Bernalillo County, New Mexico, or sources located in Indian Country. EPA is providing notice that it has approved delegation of certain NSPS to NMED, and taking direct final action to approve the delegation of certain NESHAPs to NMED.

The Texas Commission on Environmental Quality (TCEQ) has submitted updated regulations for receiving delegation of EPA authority for implementation and enforcement of National Emission Standards for Hazardous Air Pollutants (NESHAPs) for all sources (both part 70 and non-part 70 sources). These regulations apply to certain NESHAPs promulgated by the Environmental Protection Agency (EPA) at 40 CFR part 63, as amended between April 13, 2004 and April 24, 2013. The delegation of authority under this action does not apply to sources located in Indian Country. EPA is taking direct final action to approve the delegation of certain NESHAPs to TCEQ.

The Environmental Protection Agency (EPA) is approving, through a “direct final” procedure, the straight delegation of authority and approval of the mechanism used for the implementation and enforcement of certain unchanged Federal section 112 rules to the Arkansas Department of Environmental Quality (ADEQ), pursuant to section 112(l) of the Clean Air Act (Act or CAA). A more detailed description of the procedures used to implement the delegation is set forth in a memorandum of agreement (MOA) between ADEQ and EPA, dated September 17, 2014, a copy of which may be found in the docket for this rulemaking, as discussed below. The delegation only encompasses sources subject to one or more Federal section 112 standards (Part 63 standards specifically) which are also subject to the requirements of the Title V operating permits program. The delegation of authority under this action does not include authorities contained in CAA section 112(r).

This action finalizes the residual risk and technology review (RTR) conducted for the Acrylic and Modacrylic Fibers Production, Amino/Phenolic Resins Production and Polycarbonate Production source categories regulated under national emission standards for hazardous air pollutants (NESHAP). In addition, we are taking final action addressing emissions during periods of startup, shutdown and malfunction, and are adding standards for previously unregulated hazardous air pollutant (HAP) emissions sources for certain emission points. These changes include revisions made in response to comments received on the proposed rule. These final amendments also include clarifying provisions pertaining to open-ended valves and lines, adding monitoring requirements for pressure relief devices and adding requirements for electronic reporting of performance test results, as proposed. We estimate that these final amendments will reduce HAP emissions from these three source categories by a combined 137 tons per year.

On August 5, 2014, The Dow Chemical Company (Dow) requested an Alternative Means of Emission Limitation (AMEL) under the Clean Air Act (CAA) in order to operate pressure-assisted multi-point ground flares at its Propane Dehydrogenation Plant and its Light Hydrocarbons Plant at its Texas Operations site located in Freeport, Texas. On October 21, 2014, ExxonMobil Chemical Company (ExxonMobil) requested an AMEL under the CAA for its pressure-assisted multi-point ground flares at its' Olefins Plant in Baytown, Texas, and its' Plastics Plant in Mont Belvieu, Texas. In this document, the Environmental Protection Agency (EPA) is soliciting comment on all aspects of the AMEL requests and the resulting alternative operating conditions that are necessary to achieve a reduction in emissions of volatile organic compounds (VOC) and hazardous air pollutants (HAPs) at least equivalent to the reduction in emissions required by various standards in 40 CFR parts 60, 61 and 63 that apply to emission sources controlled by these pressure-assisted multi-point ground flares. These standards point to the operating requirements for flares in the General Provisions to parts 60 and 63, respectively, to comply with the emission reduction requirements. Because pressure-assisted multi-point ground flares cannot meet the velocity requirements in these General Provisions, Dow and ExxonMobil are seeking an AMEL.

The U.S. Environmental Protection Agency (EPA) is announcing the receipt of a complete petition requesting that the EPA add the chemical n-Propyl Bromide (nPB) (Chemical Abstract Service No. 106-94-5) to the list of hazardous air pollutants (HAP) contained in section 112(b)(1) of the Clean Air Act (CAA). On October 28, 2010 and November 28, 2012, the Halogenated Solvent Industry Alliance (HSIA) submitted a petition to list nPB as a HAP and a supplement to the petition, respectively. In addition, on November 24, 2011, the New York State Department of Environmental Conservation (NYSDEC) submitted a petition to add nPB to the HAP list. We have determined that these petitions are complete for purposes of this process, which means they provide sufficient information to assess the human health impacts on people living in the vicinity of facilities emitting nPB. Today's document initiates our comprehensive technical review phase of the petition process. The EPA invites the public to comment on these petitions and to provide additional data, beyond what are in these petitions, on sources, emissions, exposure, health effects and environmental impacts associated with nPB that may be relevant to our technical review. These petitions and supporting information are available through Docket ID EPA-HQ-OAR-2014-0471. Following completion of the technical review phase that is initiated by today's notice and runs through the EPA's evaluation of all the comments received, the EPA will decide whether to grant or deny the petitions.

On December 18, 2014, the Environmental Protection Agency (EPA) proposed national emission standards for hazardous air pollutants (NESHAP) for brick and structural clay products manufacturing and NESHAP for clay ceramics manufacturing. The EPA is extending the deadline for written comments on the proposed rule by 30 days to March 19, 2015. In addition, the EPA is changing the date of the public hearing, if requested, to January 27, 2015, and the date to pre-register for the hearing if it is held.

The Environmental Protection Agency (EPA) is proposing national emission standards for hazardous air pollutants (NESHAP) for brick and structural clay products manufacturing and NESHAP for clay ceramics manufacturing. The EPA is proposing that all major sources in these categories meet maximum achievable control technology (MACT) standards for mercury, non-mercury 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 proposed rule, which has been informed by input from industry and other stakeholders, including small businesses, would protect air quality and promote public health by reducing emissions of HAP listed in section 112 of the Clean Air Act (CAA).

In this action, the Environmental Protection Agency (EPA) proposes that it has completed its statutory obligation of the Clean Air Act to promulgate emissions standards for source categories accounting for not less than ninety percent of the aggregated emissions of each of the seven hazardous air pollutants enumerated in section 112(c)(6). This document explains the basis for the agency's conclusion that it completed this obligation in February of 2011, identifies the promulgated standards that collectively satisfy the obligation, and provides the public an opportunity to comment.

On November 7, 2014, the Environmental Protection Agency (EPA) proposed amendments to the national emission standards for hazardous air pollutants for Phosphoric Acid Manufacturing and Phosphate Fertilizer Production source categories and to new source performance standards for several phosphate processing categories. The EPA is extending the deadline for written comments on the proposed amendments by 30 days to January 21, 2015. The EPA received requests for an extension from The Fertilizer Institute, several phosphate facilities and a testing company that supports the industry. The Fertilizer Institute has requested the extension in order to allow more time to review the proposed rule and associated emissions data, risk assessment and technology review.

The Environmental Protection Agency (EPA) is announcing that the period for providing public comments on the November 13, 2014, supplemental proposed rule titled “NESHAP Risk and Technology Review for the Mineral Wool and Wool Fiberglass Industries; NESHAP for Wool Fiberglass Area Sources” is being extended for 30 days.

The Environmental Protection Agency (EPA) is announcing that the period for providing public comments on the October 6, 2014, supplemental proposed rule titled “National Emission Standards for Hazardous Air Pollutants: Ferroalloys Production” is being extended an additional 11 days.

The Environmental Protection Agency (EPA) is announcing that the period for providing public comments on the October 6, 2014, supplemental proposed rule titled “National Emission Standards for Hazardous Air Pollutants: Ferroalloys Production” is being extended for 18 days.

This action proposes amendments in addition to those proposed on November 25, 2011, and April 15, 2013, for the Mineral Wool Production and Wool Fiberglass Manufacturing source categories. This action addresses comments received on previous proposals, explains changes to previously proposed limits for sources in these industries and clarifies our use of the upper prediction limit (UPL) in setting MACT floors. The Environmental Protection Agency (EPA) is taking comments on only aspects of the proposed rules that are discussed in this document. When finalized, these proposed standards would increase the level of environmental protection.

The Environmental Protection Agency (EPA) is proposing amendments to the National Emission Standards for Hazardous Air Pollutants for the Phosphoric Acid Manufacturing and Phosphate Fertilizer Production source categories and to new source performance standards (NSPS) for several phosphate processing categories. The proposed amendments address the results of the residual risk and technology reviews (RTR) conducted as required under the Clean Air Act (CAA), as well as other actions deemed appropriate during the review of these standards. The proposed amendments include numeric emission limits for mercury and work practice standards for hydrogen fluoride (HF) from calciners; work practice standards for hazardous air pollutant (HAP) emissions from gypsum dewatering stacks and cooling ponds; emission standards requiring HF testing from various affected sources; clarifications to the applicability and monitoring requirements for both source categories to accommodate process equipment and technology changes; changes to remove the exemptions for startup, shutdown and malfunction; work practice standards for periods of startup and shutdown; and revised provisions to address recordkeeping and reporting requirements applicable to periods of startup, shutdown and malfunction. The proposed amendments will reduce mercury emissions, thereby reducing potential mercury exposure to children, including the unborn. Further, the EPA has conducted an 8-year review of the current NSPS for these source categories, and is proposing that no revisions to the numeric emission limits for these standards are appropriate.

This action corrects our supplemental notice of proposed rulemaking to the national emission standards for hazardous air pollutants for the Ferroalloys Production source category published in the Federal Register on October 6, 2014. In that action, there is an incorrect location for the public hearing. This document amends the public hearing location and the date the hearing will be held, if requested.

This action finalizes the residual risk and technology review (RTR) conducted for the Acrylic and Modacrylic Fibers Production, Amino/Phenolic Resins Production and Polycarbonate Production source categories regulated under national emission standards for hazardous air pollutants (NESHAP). In addition, we are taking final action addressing emissions during periods of startup, shutdown and malfunction, and are adding standards for previously unregulated hazardous air pollutant (HAP) emissions sources for certain emission points. These changes include revisions made in response to comments received on the proposed rule. These final amendments also include clarifying provisions pertaining to open-ended valves and lines, adding monitoring requirements for pressure relief devices and adding requirements for electronic reporting of performance test results, as proposed. We estimate that these final amendments will reduce HAP emissions from these three source categories by a combined 137 tons per year.

This action supplements our proposed amendments to the national emission standards for hazardous air pollutants (NESHAP) for the Ferroalloys Production source category published in the Federal Register on November 23, 2011. In that action, the Environmental Protection Agency (EPA) proposed amendments based on the initial technology and residual risk reviews for this source category. Today's action presents a revised technology review and a revised residual risk review for the Ferroalloys Production source category and proposes revisions to the standards based on those reviews. This action also proposes new compliance requirements to meet the revised standards. This action would result in significant environmental improvements through the reduction of fugitive manganese emissions and through more stringent emission limits for several processes.
