                         The TTN provides information and technology exchange in various areas of air pollution control. C. Judicial Review Under section 307(b)(1) of the Clean Air Act (CAA), judicial review of these final rules is available only by filing a petition for review in the U.S. Court of Appeals for the District of Columbia Circuit by March 26, 2007. Under section 307(d)(7)(B) of the CAA, only an objection to these final rules that was raised with reasonable specificity during the period for public comment can be raised during judicial review. Moreover, under section 307(b)(2) of the CAA, the requirements established by these final rules may not be challenged separately in any civil or criminal proceedings brought by EPA to enforce these requirements. II. Background Information for Final Area Source Standards Sections 112(c)(3) and 112(k)(3)(B) of the CAA instruct EPA to identify not less than 30 HAP which, as a result of emissions from area sources, present the greatest threat to public health in the largest number of urban areas, and to list sufficient area source categories [1]
                        
                         to ensure that sources representing 90 percent or more of the emissions of each of the 30 listed HAP (“area source HAP”) are subject to regulation. Sierra Club sued EPA, alleging a failure to complete standards for the source categories listed pursuant to CAA sections 112(c)(3) and (k)(3)(B) within the timeframe specified by the statute. 
                        *See Sierra Club*
                         v. 
                        *Johnston*, No. 01-1537, (D.D.C.). On March 31, 2006, the court issued an order requiring EPA to promulgate standards under CAA section 112(d) for those area source categories listed pursuant to CAA sections 112(c)(3) and (k)(3)(B). Among other things, the order requires that, by December 15, 2006, EPA complete standards for four of the listed area source categories. On October 6, 2006 (71 FR 59302) we proposed NESHAP for the following four listed area source categories that we have selected to meet the December 15, 2006 deadline: (1) Primary Copper Smelting; (2) Secondary Copper Smelting; (3) Polyvinyl Chloride and Copolymers Production; and (4) Primary Nonferrous Metals—Zinc, Cadmium, and Beryllium. These final NESHAP complete the required regulatory action for four area source categories. Under CAA section 112(d)(5), the Administrator may, in lieu of standards requiring maximum achievable control technology (MACT) under section 112(d)(2), elect to promulgate standards or requirements for area sources “which provide for the use of generally available control technologies or management practices by such sources to reduce emissions of hazardous air pollutants.” Under section 112(d)(5), the Administrator has the discretion to use generally available control technology (GACT) or management practices in lieu of MACT. As mentioned in the proposed NESHAP for these four area source categories, we have decided not to issue MACT standards and concluded that requirements that provide for the use of GACT or generally available management practices are appropriate for these four source categories (71 FR 59302, 59304, October 6, 2006). III. Summary of Final Rules and Changes Since Proposal A. NESHAP for Polyvinyl Chloride and Copolymers Production Area Sources As proposed, we are adopting the requirements in 40 CFR part 61, subpart F that apply to polyvinyl chloride (PVC) plants as the NESHAP for the Polyvinyl Chloride and Copolymer Production area source category. The only change since the proposed rule is that this final rule does not adopt either the startup, shutdown, and malfunction (SSM) requirements in 40 CFR 63.6(e)(3) or the preconstruction notification requirements in 40 CFR 63.5. As discussed in more detail in section IV.B of this preamble, under the construct of part 61 standards, sources must comply with the standards at all times, including periods of SSM. Because in this final rule we are adopting the part 61 standards for PVC plants as the area source standard, separate requirements governing SSM are not necessary. We have also determined that the preconstruction notification requirements at 40 CFR 63.5 are not necessary because a comparable preconstruction notification is already required under the part 61 General Provisions (40 CFR part 61, subpart A), which apply to this NESHAP. 1. Applicability and Compliance Dates This final rule applies to both new and existing PVC and copolymer plants that are area sources of HAP. The owner or operator of an existing source must comply with all the requirements of this area source NESHAP by January 23, 2007. The owner or operator of a new source must comply with this area source NESHAP by January 23, 2007 or at startup, whichever is later. 2. Emissions Limits and Work Practice Standards The Polyvinyl Chloride and Copolymers Production area source category was listed for its contribution to the emissions of the area source HAP vinyl chloride. As proposed, we are adopting the requirements in 40 CFR part 61, subpart F that are applicable to PVC plants as the NESHAP for the Polyvinyl Chloride and Copolymer Production area source category. These requirements in subpart F include numerical emissions limits for reactors; strippers; mixing, weighing, and holding containers; monomer recovery systems; emissions sources following the stripper(s); and reactors used as strippers. In addition, they include emissions limits and work practice requirements that apply to discharges from manual vent valves on a PVC reactor and relief valves in vinyl chloride service, fugitive emissions sources, and equipment leaks. Subpart F also requires a new or existing source to comply with the requirements at 40 CFR part 61, subpart V for the control of equipment leaks. As discussed in the proposal preamble, we have determined that these requirements represent GACT for sources in this area source category. 3. Compliance Requirements We are including in this NESHAP the monitoring, testing, recordkeeping, and reporting requirements in 40 CFR part 61, subpart F. This final NESHAP requires a vinyl chloride continuous emissions monitoring system (CEMS) for the regulated emissions sources (except for sources following the stripper) and for any control system to which reactor emissions or fugitive 
                        ( print page 2932)
                        emissions must be ducted. Plants using a stripper to comply with this NESHAP must also determine the daily average vinyl chloride concentration for each type of resin. The owner or operator must submit quarterly reports containing information on emissions or resin concentrations that exceed the applicable limits. Records are required to demonstrate compliance, including a daily operating log for each reactor. Plants are required to comply with the testing, monitoring, recordkeeping, and reporting requirements in the part 61 General Provisions (40 CFR part 61, subpart A). For the reasons discussed in sections III.A and IV.B of this preamble, this final NESHAP does not require that the owner or operator comply with the SSM requirements at 40 CFR 63.6(e)(3) and the preconstruction notification requirements at 40 CFR 63.5. 4. Exemption From Title V Permit Requirements Section 502(a) of the CAA provides that EPA may exempt one or more area sources from the requirements of title V if EPA finds that compliance with such requirements is “impracticable, infeasible, or unnecessarily burdensome” on such area sources. EPA must determine whether to exempt an area source from title V at the time we issue the relevant section 112 standard (40 CFR 70.3(b)(2)). For the reasons discussed in the preamble to the proposed rule, we are exempting PVC and copolymers production area sources from the requirements of title V. PVC and copolymers production area sources are not required to obtain title V permits solely as a function of being the subject of the NESHAP; however, if they were otherwise required to obtain title V permits, such requirement(s) would not be affected by this exemption. We received no comments on our proposal to exempt PVC and copolymer production area sources from the requirements of title V. B. NESHAP for Primary Copper Smelting Area Sources The Primary Copper Smelting area source category was listed for its contribution to the emissions of the area source HAP arsenic, cadmium, chromium, lead, and nickel. As discussed in more detail in section IV.C of this preamble, the major change since the proposed rule is that we established a subcategory of primary copper smelters that use the batch converting technology and developed separate standards for this subcategory. At the time of the proposed rule, we were not aware of any area sources using the batch converting technology. Since then, we received comments indicating that there may or will be primary copper smelting area sources that use the batch converting technology. Because batch technology is quite different from the continuous converting technology we used to develop the proposed standards for the Primary Copper Smelting area source category in terms of process operation, emissions points, and achievable levels of control, we believe that the proposed standards do not represent GACT for existing primary copper smelting area sources that use the batch converting technology. Accordingly, we developed a separate standard for existing sources that use the batch converting technology, and we developed that standard based on the title V permit of one batch converting facility that we have determined to be effectively controlling its HAP emissions by complying with its permit terms and conditions. In response to comments, we also made several changes to the proposed rule for primary copper smelters that do not use the batch converting technology. As explained in the preamble to the proposed rule, we have determined that certain terms and conditions in the title V permit of the only area source primary smelter of which we are aware provide effective control of HAP emissions and represent GACT for these sources. We made changes in the proposed rule to more accurately capture the relevant terms and conditions in this existing area source's title V permit. Specifically, we clarified that capture and control systems are not required for anode casting and holding operations; that the sampler required for existing sources is a continuous PM sampler; that the emissions limit is expressed as PM less than 10 microns in aerodynamic diameter (PM10) rather than PM; and that a single gas collection system could serve multiple process vessels. As discussed in section IV.B of this preamble, we allow new and existing sources to comply with either the SSM requirements in 40 CFR 63.6(e)(3) or the detailed SSM requirements in the final rule that were developed from the existing sources' title V permits, which are substantially equivalent to the SSM requirements in 40 CFR part 63. 1. Applicability and Compliance Dates This final rule applies to each new or existing primary copper smelter that is an area source of HAP. The owner or operator of an existing affected source must comply by January 23, 2007. The owner or operator of a new affected source must comply by January 23, 2007 or upon initial startup, whichever is later. An affected source is new if construction or reconstruction of the affected source was commenced on or after October 6, 2006. 2. Emissions Limits and Work Practice Standards As previously mentioned, we have developed separate standards for existing sources that use the batch converting technology and for those that do not. However, the standards for new sources apply to all new area source primary copper smelters irrespective of the converting technology utilized. Under this final rule, the owner or operator of an existing area source using any converting technology is required to control HAP emissions from copper concentrate drying, copper concentrate smelting, copper matte drying and grinding, copper matte converting, and copper anode refining. As discussed in the proposal preamble, we are using PM as a surrogate for HAP metals. Gases and fumes generated by these processes must be captured and vented through one or more PM control devices. For existing primary copper smelters that do not use the batch converting process, the total emissions of PM10 from the captured gas streams from all of these processes is limited to 89.5 pounds per hour (lb/hr) as determined on a 24-hour average basis. For existing primary copper smelters using the batch converting technology, the exhaust gases from each smelter vessel and each converter must be collected and sent to a PM control device and to a sulfuric acid plant. A secondary gas collection system must be installed on each smelting vessel and converter, and PM emissions from the secondary capture and control system must not exceed 0.02 grains per dry standard cubic foot (gr/dscf). The PM emissions from each copper concentrate dryer must not exceed 0.022 gr/dscf. Similarly, the owner or operator of a new area source using any converting technology must control HAP emissions from all primary copper smelting processes, including but not limited to those processes mentioned above that are applicable to the new source's smelter design. Gases and fumes generated by these processes at a new source must be captured and vented through one or more PM control devices. We are requiring a new source to achieve a facility input-based emissions rate for total PM no greater than a daily (24-hour) average of 0.6 pounds per ton (lb/ton) of copper concentrate feed charged to the smelting vessel. This final rule for new area source primary copper smelters also requires a secondary gas system for each smelting 
                        ( print page 2933)
                        vessel and converting vessel that collects the gases and fumes released during the molten material transfer operations and conveys the collected gas stream to a control device. Capture systems that collect gas and fumes and convey them to a control device also are required for operations in the anode refining. These capture and control requirements apply to all new and existing area sources using any copper smelting technology. 3. Compliance Requirements In this final rule, we have adopted the testing, monitoring, operation and maintenance, recordkeeping, and reporting requirements for PM emissions that are in the title V permits of the existing area source smelters. Compliance with the emissions limit for existing area sources not using the batch converting technology is based on the daily average PM10
                         emissions measured by a continuous PM sampler. For smelters using the batch conversion technology, compliance is based on performance tests at least every 2.5 years and continuous monitoring using continuous opacity monitoring systems (COMS) for electrostatic precipitators and bag leak detection systems for baghouses. The operation and maintenance requirements in this final rule for existing sources using any converting technology are based on the existing sources' title V permits. At all times, the owner or operator must to the extent practicable, maintain and operate any affected source, including associated air pollution control equipment, in a manner consistent with good air pollution control practice for minimizing emissions. In addition, all pollution control equipment must be installed, maintained, and operated properly. Instructions from the vendor or established maintenance practices that maximize pollution control must be followed. Maintenance records must be made available to the permitting authority upon request. This final rule allows any new or existing source to meet the SSM requirements specified in this final rule or the SSM requirements in 40 CFR 63.6(e)(3). The SSM requirements that are specified in this final rule were developed from the existing sources' title V permit requirements, and we believe these requirements are equally applicable to new and existing area sources irrespective of the converting technology used. Sources may nevertheless choose to comply with the SSM provisions in 40 CFR 63.6(e)(3), in lieu of the SSM requirements specified in this final rule. The SSM provisions in this final rule require that all malfunctions be reported within two working days of the event. The report must include a description of the malfunction, steps taken to mitigate emissions, and corrective actions taken. In addition, the owner or operator must show through signed contemporaneous logs or other relevant evidence that: (1) A malfunction occurred and the probable cause can be identified, (2) the facility was being operated properly at the time the malfunction occurred, and (3) all reasonable steps were taken to minimize emissions that exceeded the emission standards. A malfunction or emergency does not include events caused by improperly designed equipment, lack of preventative maintenance, careless or improper operation, or operator error. The owner or operator of an existing area source using any copper smelting technology must comply with notification requirements in 40 CFR 63.9 of the General Provisions (40 CFR part 63, subpart A). In the notification of compliance status required in 40 CFR 63.9(h), the owner or operator may certify initial compliance with the emissions limit based on monitoring data collected during a previous compliance test. The owner or operator also must certify initial compliance with the work practice standards. The owner or operator of a new primary copper smelter must install, operate, and maintain a CEMS to measure and record PM concentrations and gas stream flow rates for each emissions source subject to the emissions limit. The standard requires that the PM CEMS meet EPA Performance Specification 11 (40 CFR part 60, appendix B). A device to measure and record the weight of the copper concentrate feed charged to the smelting furnace each day also is required. The owner or operator must continuously monitor PM emissions, determine and record the daily (24-hour) value for each day, and calculate and record the daily average pounds of total PM per ton of copper concentrate feed charged to the smelting furnace. A monthly summary report of the daily averages of PM per ton of copper concentrate feed charged to the smelting vessel also is required. All notification, monitoring, testing, operation and maintenance, recordkeeping, and reporting requirements of the part 63 General Provisions apply to the owner or operator of a new source. This final rule allows a new source to meet the specific SSM requirements that were developed from the title V permit requirements for existing sources or the SSM requirements in 40 CFR 63.6(e)(3). C. NESHAP for Secondary Copper Smelting Area Sources We did not receive any comments on our determination of GACT for secondary copper smelters, and we are promulgating the standard as proposed without any changes. 1. Applicability and Compliance Dates This final rule applies to each new secondary copper smelter that is an area source of HAP. The owner or operator of a new affected source is required to comply by January 23, 2007 or upon initial startup, whichever is later. 2. Emissions Limit and Work Practice Standards This final rule does not include requirements for existing area sources of secondary copper smelters. As we explained in the preamble to the proposed rule, currently there are no existing major or area sources of secondary copper smelters. Therefore, there is not any, nor would there ever be, an existing secondary copper smelter that would be subject to this rule. In this circumstance, we are not issuing standards for existing area sources of secondary copper smelters. However, this final rule contains requirements for new area sources of secondary copper smelters. The Secondary Copper Smelting area source category was listed for its contribution to the emissions of the area source HAP cadmium, lead and dioxin. We have established requirements for new sources in this category to ensure that any potential emission of these area source HAP from future secondary copper smelting area sources will be appropriately controlled. We are requiring that the owner or operator of any new secondary copper smelter operate a capture and control system for PM emissions from any process operation that melts copper scrap, alloys, or other metals or that processes molten material. Emissions of PM from the control device must not exceed 0.002 gr/dscf. The owner or operator must also prepare and follow a written plan for the selection, inspection, and pretreatment of copper scrap to minimize, to the extent practicable, the amount of oil and plastics in the scrap that is charged to smelting or melting furnaces. As we explained in the proposal preamble, we are using PM as a surrogate for establishing standards for metal HAP, which are cadmium and lead in this case. The United Nations Environmental Programme (UNEP) has also recommended using control devices with high efficiency PM removal to reduce dioxin emissions. The pollution 
                        ( print page 2934)
                        prevention measure described above (i.e., presorting and pretreating materials) is another UNEP recommendation for reducing dioxin emissions. We have determined that these requirements represent GACT for new sources of secondary copper smelters and requested comments on this determination in the proposed rule. We did not receive any comments on this determination. 3. Compliance Requirements Fabric filters (baghouses) are expected to be needed to meet the NESHAP emissions limit. Consequently, the monitoring requirements include bag leak detection systems when baghouses are used. For additional information on bag leak detection systems that operate on the triboelectric effect, see “Fabric Filter Bag Leak Detection Guidance”, U.S. Environmental Protection Agency, Office of Air Quality Planning and Standards, September 1997, EPA-454/R-98-015, NTIS publication number PB98164676. This document is available from the National Technical Information Service (NTIS), 5385 Port Royal Road, Springfield, VA 22161. The owner or operator must prepare a written plan for the selection, inspection, and pretreatment of copper scrap and keep records to document conformance with the requirements in the written plan. If a control device other than a baghouse is used, the owner or operator must submit a monitoring plan to the permitting authority for approval. The monitoring plan must include performance test results showing compliance with the PM emissions limit, a plan for operation and maintenance of the control device, a list of operating parameters that will be monitored, and operating parameter limits that were established during the performance test. The owner or operator must conduct a performance test to demonstrate initial compliance with the PM emissions limit and report the results in the notification of compliance status required by 40 CFR 63.9(h) of the General Provisions. If a baghouse is used, the PM concentration is to be determined using EPA Method 5 (for negative pressure baghouses) or Method 5D (for positive pressure baghouses) in 40 CFR part 60, appendix A. Repeat performance tests are required every 5 years to demonstrate compliance with the PM emissions limit. All requirements of the part 63 General Provisions apply to the owner or operator of a new source, including the notification, monitoring, testing, operation and maintenance, SSM, recordkeeping, and reporting requirements. D. NESHAP for Primary Nonferrous Metals—Zinc, Cadmium, and Beryllium Area Sources 1. NESHAP for Primary Zinc Production In this final rule, we have adopted a limit in grains per dry standard cubic foot (gr/dscf) for certain melting furnaces at existing zinc production area sources in addition to the proposed pound per hour (lb/hr) limits for these furnaces at existing sources. This gr/dscf limit is the limit that we proposed for the same furnaces at new sources. Both the gr/dscf limit and the lb/hr limits reflect the level of emission control that can be achieved based on the technology we identified as GACT for these furnaces (i.e., a well-operated and well-maintained baghouse). However, whereas the lb/hr limits were based on the specific operations at the two existing sources of which we are aware, the gr/dscf emission limit is not operation specific and can apply to these furnaces at any primary zinc production area source irrespective of its operation. For this reason, we proposed this gr/dscf emissions limit for these furnaces at new sources. In this final rule, we similarly allow an existing source to meet this gr/dscf limit for these furnaces. This final rule provides existing sources the option of meeting either the lb/hr limits or the gr/dscf limit for these furnaces. We believe that including both the lb/hr and gr/dscf limits in this final rule will ensure effective control of these furnaces at all existing primary zinc production area sources in the event that there are facilities other than the two we know and with very different operations from the two known sources. In addition, as discussed in section IV.B of this preamble, we allow new and existing sources to comply with either the SSM requirements in 40 CFR 63.6(e)(3) or with the detailed SSM requirements in the final rule that were developed from the existing sources' title V permits, which are substantially equivalent to the SSM requirements in part 63. *Applicability and compliance dates.*
                         This final rule applies to each new or existing primary zinc production facility that is an area source of HAP. The owner or operator of an existing affected source must comply by January 23, 2007. The owner or operator of a new affected source must comply by January 23, 2007 or upon initial startup, whichever is later. *Emissions limits and work practice standards.*
                         Primary zinc production facilities were included as part of the Primary Nonferrous Metals area source category due to their contributions to the emissions of the area source HAP arsenic, cadmium, lead, manganese, and nickel, all of which are metal HAP. As we mentioned in the proposal preamble, cadmium is produced as a by-product of zinc smelting processes. There are no primary cadmium smelters in the United States. Accordingly, the requirements for area sources of zinc production in this final rule also address emissions associated with any cadmium production at these zinc production facilities. As previously mentioned, we are using PM as a surrogate for establishing standards for metal HAP. Under this final rule, the owner or operator of an area source of zinc production is required to exhaust roaster off-gases to PM removal equipment and a sulfuric acid plant. Bypassing the sulfuric acid plant during charging of the roaster is prohibited. Emissions limits apply to the different types of melting furnaces at primary zinc production facilities. For existing sources, this NESHAP limit PM emissions to 0.93 lb/hr for zinc cathode melting furnaces; 0.1 lb/hr for furnaces that melt zinc dust, chips, and off-specification zinc materials; and 0.228 lb/hr for the combined exhaust from furnaces that melt zinc scrap and alloys. As an alternative to the lb/hr limits for these furnaces at existing sources, the owner or operator may elect to meet a limit of 0.005 gr/dscf. For new sources, the PM limit is 0.005 gr/dscf for the furnaces mentioned above. Other PM limits are 0.014 gr/dscf for anode casting furnaces and 0.015 gr/dscf for cadmium melting furnaces at new and existing sources. Emissions limits also apply to any sintering machine at a new or existing area source facility. If there is a sintering machine, the owner or operator must comply with the PM limit at 40 CFR 60.172 and the opacity limit at 40 CFR 60.174(a) of the new source performance standard (NSPS) for primary zinc smelters (40 CFR part 60, subpart Q). *Compliance requirements.*
                         We are adopting for existing area sources certain monitoring, recordkeeping, and reporting requirements in the title V permits of the two existing facilities that relate to PM emissions control. The owner or operator of an existing area source must monitor baghouse pressure drop, perform routine baghouse maintenance, and keep records to document compliance. In addition, we are requiring repeat performance tests (at least once every 5 years) for existing sources. This final rule also requires a continuous opacity monitoring system (COMS) for any sintering machine in accordance with 40 CFR 60.175. 
                        ( print page 2935) The owner or operator of an existing area source must comply with initial notification requirements in 40 CFR 63.9 of the General Provisions. In the notification of compliance status required by 40 CFR 63.9(h), the owner or operator may certify initial compliance with the HAP emissions limits based on the results of a PM performance test for each of the regulated emissions sources conducted within the past 5 years. The owner or operator must also certify initial compliance with the work practice standards. If an existing source has not conducted a performance test to demonstrate compliance with the emissions limits for a furnace, the facility must conduct a test according to the requirements at 40 CFR 63.7 using EPA Method 5 (40 CFR part 60, appendix A) to determine the PM concentration or an alternative method previously approved by the permitting authority. For a sintering machine, the owner or operator must conduct a performance test according to the procedures in 40 CFR 60.176(b) using EPA Method 5 to determine the PM concentration and EPA Method 9 (40 CFR part 60, appendix B) to determine the opacity of emissions. The operation and maintenance requirements in the final rule for existing sources are based on the sources' title V permits. The owner or operator must maintain all equipment covered under the subpart in such a manner that the performance or operation of the equipment does not cause a deviation from the applicable requirements. A maintenance record must be kept for each item of air pollution control equipment. At a minimum, this record must show the dates of performing maintenance and the nature of preventative maintenance activities. This final rule allows any existing source to meet the specific SSM requirements that were developed from the title V permit requirements for existing sources or the SSM requirements in 40 CFR 63.6(e)(3). The specific SSM provisions in this final rule require that all malfunctions be reported within two working days of the event. The report must include a description of the malfunction, steps taken to mitigate emissions, and corrective actions taken. In addition, the owner or operator must show through signed contemporaneous logs or other relevant evidence that: (1) A malfunction occurred and the probable cause can be identified, (2) the facility was being operated properly at the time the malfunction occurred, and (3) all reasonable steps were taken to minimize emissions that exceeded the emission standards. A malfunction or emergency does not include events caused by improperly designed equipment, lack of preventative maintenance, careless or improper operation, or operator error. As required in the existing permits, the owner or operator must submit a notification to the permitting authority of any deviation from the requirements of this final NESHAP. The notification must describe the probable cause of the deviation and any corrective actions or preventative measures taken. Existing facilities are also required to submit semiannual monitoring reports which clearly describe any deviations. Records of baghouse maintenance, all required monitoring data, and support information also are required. The owner or operator of an existing area source must also comply with the notification requirements in 40 CFR 63.9 of the General Provisions. The owner or operator of a new area source is required to install and operate a bag leak detection system for each baghouse used to comply with a PM emissions limit. For additional information on bag leak detection systems that operate on the triboelectric effect, see “Fabric Filter Bag Leak Detection Guidance”, U.S. Environmental Protection Agency, Office of Air Quality Planning and Standards, September 1997, EPA-454/R-98-015, NTIS publication number PB98164676. This document is available from the National Technical Information Service (NTIS), 5385 Port Royal Road, Springfield, VA 22161. In addition, we are requiring repeat PM performance tests (once every 5 years) for each furnace at a new source. The owner or operator must also install, operate, and maintain a COMS for each sintering machine according to EPA Performance Specification 1 (40 CFR part 60, appendix B). The owner or operator of a new affected source must demonstrate initial compliance with the applicable emissions limits by conducting a performance test according to the requirements at 40 CFR 63.7 and using EPA 5 or 5D (40 CFR part 60, appendix A), as applicable, to determine the PM concentration. An initial performance test is also required for a sintering machine according to the methods and procedures in 40 CFR 60.176(b). All of the notification, testing, monitoring, operation and maintenance, recordkeeping, and reporting requirements of the part 63 General Provisions apply to a new area source. This final rule allows a new source to meet the specific SSM requirements in this final rule or the SSM requirements in 40 CFR 63.6(e)(3). 2. NESHAP for Primary Beryllium Production Area Sources The only change since proposal is that this final rule does not adopt the SSM requirements in 40 CFR 63.6(e)(3) and the preconstruction notification requirements in 40 CFR 63.5. As discussed in more detail in section IV.B of this preamble, we have determined that the SSM requirements are not necessary for standards under part 61 that must be met at all times, and the preconstruction notification is already required under the part 61 General Provisions. *Applicability and compliance dates*. For this final rule, we are adopting all of the requirements in the National Emission Standard for Beryllium at 40 CFR part 61, subpart C. The owner or operator of an existing area source must comply with this NESHAP by January 23, 2007. The owner or operator of a new area source must comply by January 23, 2007 or at startup, whichever is later. *Emissions limits*. Primary beryllium production facilities were included as part of the Primary Nonferrous Metals area source category due to their contributions to the emissions of the area source HAP arsenic, cadmium, lead, manganese, and nickel, all of which are metal HAP. As discussed in the proposal preamble, we are using beryllium as a surrogate for HAP metals. We are adopting the 40 CFR part 61, subpart C standard as the requirements for both new and existing primary beryllium production facilities in this final rule. The part 61, subpart C standard limits emissions from extraction plants (i.e., primary beryllium production facilities) to 10 grams (0.022 lb) of beryllium over a 24-hour period. Alternatively, the owner or operator of a beryllium production facility may request to meet an ambient concentration limit instead of the emissions limit. As discussed in the preamble to the proposed rule, the part 61 standard is highly effective in controlling PM and metal HAP emissions from the only existing beryllium production facility known to us at the time of the proposal. We have determined that these requirements reflect GACT for area sources of beryllium production. We did not receive any comments on this determination. *Compliance requirements*. This final rule requires the owner or operator to comply with the testing, monitoring, recordkeeping, and reporting requirements in 40 CFR part 61, subpart 
                        ( print page 2936)
                        C. An owner or operator subject to the ambient concentration limit must operate air sampling sites to continuously monitor the concentrations of beryllium in the ambient air according to an EPA-approved plan. The owner or operator must comply with recordkeeping requirements in 40 CFR part 61, subpart C, as well as the testing, monitoring, recordkeeping, and reporting requirements in the part 61 General Provisions in 40 CFR part 61, subpart A. For the reasons discussed in section IV.B of this preamble, this final rule does not require that the owner or operator comply with the requirements for SSM plans and reports in 40 CFR 63.6(e)(3) or the preconstruction notification requirements in 40 CFR 63.5. IV. Summary of Comments and Responses A. Existing Area Source Facilities At proposal, we stated that we did not know of any existing sources in the Polyvinyl Chloride and Copolymer area source category, and we requested comments on whether there are or ever will be any area sources in this area source category. We also stated that currently there is only one area source of primary copper production in operation in the United States and that there are no primary beryllium production area sources. *Comment:*
                         One commenter informed us of an area source PVC plant in Alabama. In addition, two commenters stated that there are a few (at least three) PVC plants that they believe may qualify as area sources. According to the commenters, these were once major sources that have reduced HAP emissions significantly or that are currently shut down but are expected to start up again with significantly less emissions than from previous operations as major sources. The commenters requested that EPA clarify the meaning of “potential to emit” in its definition of an “area source” in the proposed rule, as well as the proposed rule's applicability to plants that have obtained or, for the ones that are not currently operating, will obtain permits that limit emissions to levels below the major source thresholds. In addition, the commenters requested clarification of the proposed rule's applicability to PVC plants co-located at chemical complexes that are major sources. One commenter notified us of an area source primary beryllium plant in Utah. The commenter sought clarification of the proposed rule's applicability to a primary beryllium plant that is a major source because of perchloroethylene emissions and that may become an area source in the future by eliminating the use of perchloroethylene. We also received comments that there are two operating primary copper smelters that are area sources rather than just one, as EPA stated in the proposed rule. The company operating this second source reported that it was an area source (synthetic minor) based on a determination by the permitting authority. The company also stated that it is planning to restart a primary copper smelter in Texas that has been shutdown and under “care and maintenance” for several years. This facility will incorporate feedstock limitations to remain below major source thresholds, and the company expects that this facility will qualify as an area source when the renewed permits are issued. The commenter sought clarification of the applicability of the proposed rule to the two primary copper smelters described above. *Response:*
                         Section 112(a) of the CAA defines the terms “major source” and “area source.” An “area source” is defined as any stationary source that is not a major source. In the proposed rule, we included a definition for “area source” and that definition attempted to summarize the statutory definitions of “major source” and “area source.” Commenters sought clarification of the meaning of the term “potential to emit” contained in the proposed definition of “area source.” Based on the comment, it appears that the proposed definition of “area source” has caused confusion. Because the proposed definition of “area source” was merely intended to summarize the statutory definitions of “major source” and “area source” and is redundant of the definition of “area source” contained in the General Provisions (40 CFR part 63, subpart A), we have decided not to finalize the proposed “area source” definition. Instead, as noted in the NESHAP for each of these four area source categories, the definitions of “major source,” “area source,” and “potential to emit” in 40 CFR 63.2 apply to this final rule.[2]
                        
                         To the extent the commenters have questions as to whether their facility is a major source or an area source, EPA cannot answer these site-specific applicability questions in the context of this national rulemaking. We refer the commenters to the definitions of “major source,” “area source,” and “potential to emit” found in 40 CFR 63.2, and recommend that the commenters consult with the relevant permitting authority or submit a request for an applicability determination to the EPA regional office in the region where the source is located. In addition, we want to clarify that a plant that is co-located with other facilities that together qualify as a major source is part of that major source and not an area source. B. Part 63 General Provisions *Comment:*
                         One commenter representing the two beryllium plants objected to the part 63 SSM requirements in the proposed NESHAP for the Primary Beryllium Production area source category. The commenter stated that these two beryllium plants are already subject to 40 CFR part 61, subpart C, which EPA has adopted in this final rule, as well as the SSM requirements in State implementation plans (SIP), State laws, and title V permits. According to the comment, because these plants are subject to a strict ambient air standard for beryllium under the part 61 NESHAP, which requires that the plants monitor continuously and meet the required limits under all conditions, the part 63 SSM requirements are not necessary. Commenters representing facilities in the PVC industry provided similar comments. In addition, they stated that by requiring compliance with part 61 and the SSM provisions in 40 CFR 63.6, the proposed rule would impose two different SSM schemes in one standard. It would also impose more burdensome reporting and recordkeeping obligations on the lower emitting (area) sources. Representatives of two primary copper companies also stated that the SSM requirements are unnecessary and duplicative of existing requirements and should be deleted. Their title V permits contain existing functionally equivalent 
                        ( print page 2937)
                        SSM provisions, including requirements for timely notification and reporting. *Response:*
                         We agree that the SSM requirements in the 40 CFR part 63 General Provisions need not be included in the NESHAP for the PVC and Copolymer Production and the Primary Beryllium Production area source categories, both of which adopted the relevant part 61 standards for these categories. Under the construct of the part 61 standards, sources must comply with the standards at all times, including periods of SSM. Therefore, separate requirements governing SSM are not necessary. Accordingly, we have revised the proposed rule to eliminate the part 63 SSM requirements for new and existing primary beryllium and PVC plants. We also examined the SSM requirements that are in title V permits for other source categories. The primary copper smelters and primary zinc production plants have similar requirements in their permits. Our review indicates that these requirements are substantially equivalent to the part 63 SSM requirements. For example, the title V permits for these plants require that all malfunctions be reported within two working days of the event. The report must include a description of the malfunction, steps taken to mitigate emissions, and corrective actions taken. In addition, the permittee must show through signed contemporaneous logs or other relevant evidence that: (1) A malfunction occurred and the permittee can identify the probable cause, (2) the facility was being operated properly at the time the malfunction occurred, and (3) all reasonable steps were taken to minimize emissions that exceeded the emission standards or other requirements of the permit. The permit also makes it clear that a malfunction or emergency does not include events caused by improperly designed equipment, lack of preventative maintenance, careless or improper operation, or operator error. Based on the comments and our review of title V permits, we are including in this final rule alternative SSM requirements that we have formulated based on our review of the title V permits mentioned above. Under this final rule, a new or existing primary copper smelter or primary zinc production facility may choose to meet the SSM requirements in 40 CFR 63.6(e)(3) or the alternative SSM requirements provided in this final rule. This final rule also includes operation and maintenance requirements for existing sources that are based on the permits. For primary copper smelters, the owner or operator must to the extent practicable, maintain and operate any affected source, including associated air pollution control equipment, in a manner consistent with good air pollution control practice for minimizing emissions. In addition, all pollution control equipment must be installed, maintained, and operated properly. Instructions from the vendor or established maintenance practices that maximize pollution control must be followed. All necessary equipment control and operating devices, such as pressure gauges, ampere meters, volt meters, flow rate indicators, temperature gauges, continuous emissions monitoring systems, etc., must be installed, operated properly and easily accessible to compliance inspectors. A copy of all manufacturers' operating instructions for pollution control equipment and pollution emitting equipment must be maintained at the facility site. These instructions must be available to all employees who operate the equipment and must be made available to the permitting authority upon request. Maintenance records must be made available to the permitting authority upon request. *Comment:*
                         One commenter stated that we should not adopt the preconstruction notification requirements in the part 63 General Provisions (40 CFR part 63, subpart A) because they were unnecessary and duplicate the very similar requirements already in the part 61 General Provisions (40 CFR part 61, subpart A). EPA should not impose the additional burden of submitting and processing two duplicative applications and should just rely on the provisions already in the part 61 General Provisions. *Response:*
                         We agree that if a preconstruction notification is submitted under the part 61 General Provisions (40 CFR 61.07), it is not necessary to submit another preconstruction notification under the part 63 General Provisions. We have revised the proposed rule to reflect this change. *Comment:*
                         One commenter stated that EPA should not incorporate any of the part 63 General Provisions into area source standards that adopt the part 61 NESHAP. These provisions, including those in 40 CFR 63.1 (Applicability), are already addressed in the part 61 General Provisions and enhanced by SIP requirements and title V permits. *Response:*
                         We have previously addressed the SSM requirements and preconstruction notifications for facilities subject to part 61 standards. The only other section of the part 63 General Provisions that we have included for these sources deals with applicability in 40 CFR 63.1 (§§ 63.1(a)(1) through (10), 63.1(b)(1), 63.1(c), and 63.1(d)). The provisions on applicability impose no burden on the facility and provide clarity and useful information related to the applicability of standards under part 63. Consequently, the final rule includes portions of § 63.1 from the part 63 General Provisions. C. Primary Copper Smelters *Comment:*
                         Two commenters identified two primary copper smelters as area sources in addition to the one smelter identified as an area source in the proposal preamble. One of these smelters is operating, and the company stated that the facility is an area source (i.e., a synthetic minor source). The other smelter has been shut down for several years, but it is in the process of obtaining permits to re-start and expects to be an area source. Both of these smelters use the batch converting process, whereas the smelter that was identified as an area source at proposal and was the basis for GACT uses flash continuous converting technology. The company pointed to the process descriptions in the proposal preamble that noted the numerous differences in the two technologies. The company suggested that their two smelters fit into a separate subcategory (batch converting technology) and should have rule requirements based on that technology. The requirements in the proposed rule are not appropriate for their smelters because the proposed rule is based on the flash continuous converting technology. *Response:*
                         The commenters asserted that there are two area source primary copper smelters that use the batch converting technology. As we described in the proposal preamble (71 FR 59308, October 6, 2006), there are numerous differences in process operation, emissions points, and achievable levels of control. We believe that our proposed standard for existing sources, which is based on flash continuous converting technology, would not be appropriate for existing sources of primary copper smelting that use the batch converting technology and that separate standards are needed to address the different technology used by these existing smelters. Solely for purposes of this analysis, we accept, as true, the commenter's assertion that there are existing area source facilities that use batch processing. As explained above, to the extent the commenter has any question as to whether the smelters identified above are major or area sources, they should consult with the relevant permitting authority or submit 
                        ( print page 2938)
                        a request for an applicability determination to the EPA regional office in the region where the source is located. In developing the requirements for sources using the batch converting technology, we reviewed the title V permit of the currently operating source identified in the comment. The emissions from this facility are controlled as a result of its title V permit requirements to capture and control emissions of PM. The vast majority of the gases from the smelting furnace and converter are collected by a primary capture system, sent to control equipment to remove PM, and then processed in a sulfuric acid plant. Fugitive emissions are collected by a secondary capture system and sent to a baghouse for control of PM emissions. We determined that these current permit requirements represent GACT for existing primary copper smelters using the batch converting process and have included these requirements in this final rule as the requirements for existing primary copper smelting area sources that use batch converting technology. According to these requirements, plants that use batch converting technology must operate primary capture systems on each smelting vessel and each copper converter. Secondary capture systems must be installed to capture emissions from tapping copper matte and slag from the smelting vessel and emissions from charging, skimming, pouring, and holding when the converter mouth is partially rotated out from the primary collection hood. All of the collected gases must be routed to an emissions control system. In addition, emissions from the primary collection system for the smelting vessel and converter must be routed to a sulfuric acid plant after PM removal. Emissions from each copper concentrate dryer must be controlled and must not exceed 0.022 gr/dscf. Emissions from secondary capture systems that are not vented to a sulfuric acid plant must not exceed 0.02 gr/dscf. We also examined the monitoring requirements in the title V permit of this primary smelter using the batch technology and found that they would ensure that control devices are working properly on a continuous basis. We therefore included these monitoring requirements in this final rule as requirements for primary copper smelting area sources that use the batch converting technology. Under these requirements, a COMS meeting Performance Specification 1 (40 CFR part 60, appendix B) must be installed on each electrostatic precipitator. If the 24-hour rolling average opacity exceeds 15 percent, the plant must investigate the cause of the problem and take corrective action. Each baghouse must be equipped with and monitored by a bag leak detection system to ensure proper operation. We have also required performance tests every 2.5 years to determine compliance with PM limits. *Comment:*
                         A commenter representing the primary copper plant that was the basis for GACT stated that EPA did not properly capture the facility's title V permit requirements in some cases. The commenter supplied additional details and clarifications. Clarification is needed for the requirements for anode casting and holding operations, the emissions limit should not be referred to as “smelter wide” but as the limit for the main stack, the limit should be expressed as PM10
                         rather than PM, and the continuous PM sampler should not be referred to as a CEMS. The commenter also asked that EPA modify the proposed rule to clearly state that a single secondary gas collection system can capture and control emissions from multiple processing vessels (i.e., each vessel does not have to have its own separate collection system). The commenter also requested more flexibility in the monitoring requirements so that the permitting authority could approve improved monitoring technology should it become available in the future. *Response:*
                         We agree with the commenter and will make most of the suggested changes. The facility's title V permit was the basis for our GACT determination, and we intended that the proposed area source rule incorporate the permit requirements of this well-controlled facility. We understand that in some cases, a gas collection system may be applied to multiple process vessels, and we have included this clarification in this final rule. We understand that flexibility in monitoring is important, especially as improved monitoring techniques become commercially available and demonstrated in metallurgical operations. That said, it is not necessary to revise the proposed rule to allow a facility to request approval of an alternative monitoring method because the procedure for making such requests is contained in 40 CFR 63.8, which applies to the NESHAP for the Primary Copper Smelting area source category in this final rule. *Comment:*
                         One commenter noted that the new source standard for primary copper was based on the newer flash continuous converter technology and would not be appropriate for new plants using the batch converting technology. The commenter stated that continuous converting has more limited applicability to ore concentrates that have high impurities levels than does batch converting. The commenter stated that because a new smelter could use either of the technologies, the emission standards for new sources should be reflective of the performance of either of these technologies. This can be achieved by providing flexibility in the emission limits that are adopted. The commenter recommended that the standard for new smelters using the batch converting technology be based on the best performing existing facility with the technology. In addition, a provision should be made to allow an alternate emissions limit to be authorized by either EPA or the permitting authority that is equally protective. *Response:*
                         The emissions limit that we proposed for new primary copper smelters is in lb/ton of copper concentrate feed and is applied on a facility wide basis. The format and requirements of the standard can be applied to and achieved by a facility using any primary copper smelting technology if it is well controlled. The format of the standard also provides flexibility because multiple process vessels can have different levels of emissions as long as they collectively meet the overall lb/ton limit. The limit has been demonstrated as achievable by an existing area source that uses a continuous converting process. Unlike existing sources, new sources using any smelting technology have the opportunity to incorporate state-of-the-art capture and control systems into their design, construction, and operation. Based on our engineering experience with capture and control systems that have been applied to primary copper processes and also those that have been applied to similar processes in other metallurgical industries, we believe that the emissions limit for new sources can be achieved by primary copper smelters using any processing technology, including both the continuous and batch converting processes. The standard for new primary copper smelters represents a level of control that is generally available for new sources. Consequently, we chose to promulgate the limit as proposed as GACT for new primary copper smelters. *Comment:*
                         Three commenters objected to the requirement of using a PM CEMS for monitoring at new primary copper smelter area sources. Although improvements in PM CEMS have been made as they continue to be developed, there is not sufficient operating history 
                        ( print page 2939)
                        to prove its feasibility for continuous monitoring at primary copper smelters. *Response:*
                         The PM CEMS have been demonstrated in many different applications, including processes with exhaust gases similar to those from primary copper smelters (e.g., at electric utilities where the temperatures and exhaust gas compositions are similar). The commenters did not provide any information that the exhaust gases from primary copper smelting are uniquely different. We have included PM CEMS as the monitoring technology for new sources in this final rule. D. Primary Zinc Smelters *Comment:*
                         One commenter asked if the proposed rule was meant to apply to any zinc refinery that processes any amount of zinc sulfide concentrate. If so, what is the timeframe for using zinc sulfide concentrate and its percentage of the feed that qualifies a facility as a primary zinc smelter? Is EPA really trying to regulate zinc refineries, which produce cathodes in a cathode melting furnace and use zinc sulfide concentrate as a feed material, and not regulate thermal zinc smelters, who do not produce cathodes and do not currently use zinc sulfide concentrate? *Response:*
                         The commenter is correct in that this final rule applies to any area source facility that produces zinc products from any amount of zinc sulfide ore concentrates using pyrometallurgical processes (i.e., a “primary zinc smelter”). This final rule does not apply to thermal zinc smelters if they do not process zinc sulfide concentrate. (Facilities processing only zinc scrap and residues containing zinc would be classified as secondary zinc smelters.) If a facility meets the definition of primary zinc smelter and is an area source on the compliance date, it is subject to this final rule. If the facility is not processing zinc sulfide concentrate but subsequently begins processing it, meets the definition of primary zinc smelter, and is an area source, it is subject to this final rule when it begins processing the zinc sulfide concentrate. Under these facts, such a facility would be subject to the standards for new sources if construction or reconstruction of the primary zinc smelter (the affected source) commenced on or after October 6, 2006. We are not making a distinction between zinc refineries and thermal zinc smelters as described by the commenter. Either type of facility is subject to this final rule if it is an area source and meets the definition of primary zinc smelter. *Comment:*
                         One commenter noted that the proposed rule requires demonstrating compliance by stack testing within 180 days after the compliance date. Their plant has a process that is not operating, it is subject to the rule, but it may not restart until more than 180 days after the compliance date. As the proposed rule reads, they would have to demonstrate compliance by a stack test even though the process is not operating. *Response:*
                         We have clarified the proposed rule to indicate that if a process subject to this final rule is not operating on the compliance date and subsequently starts up, compliance testing must be performed within 180 days after startup of the process. *Comment:*
                         One commenter noted that the proposed rule requires that initial compliance must be demonstrated “for each furnace at your facility.” A zinc smelter may have other types of furnaces that are not subject to emission limits. The commenter assumes that this requirement will have no impact on these furnaces. *Response:*
                         The commenter is correct. We have clarified the proposed rule to state that initial compliance must be demonstrated “for each furnace at your facility that is subject to an emissions limit under this subpart.” *Comment:*
                         One commenter stated that the emissions limit of 0.005 gr/dscf for certain furnaces at new sources is greater than the emissions limit for the same furnaces at existing sources. The commenter suggested that the greater of the two values be applied in this case to provide a level playing field for new and existing sources. *Response:*
                         We disagree with the comment that the emissions limit of 0.005 gr/dscf for certain furnaces at new sources is greater than the emissions limits for the same furnaces at existing sources. The emissions limit of 0.005 gr/dscf for new sources is applied to the exhaust vent of a zinc cathode melting furnace; scrap zinc melting furnace; furnace melting zinc dust, zinc chips, and other materials containing zinc; and alloy melting furnace. For existing sources, the limits are 0.1 lb/hr from the exhaust vent of a furnace that melts zinc dust, zinc chips, and/or other materials containing zinc; and 0.228 lb/hr from the vent for the combined exhaust from a furnace melting zinc scrap and an alloy furnace. Although the limits for the furnaces mentioned above are expressed in different formats for new and existing sources, both formats reflect the level of emission control that can be achieved based on the technology we identified as GACT for these furnaces (i.e., a well-operated and well-maintained baghouse). However, whereas the lb/hr limits for the above-noted furnaces in the proposed rule were based on the specific operations at the two existing sources of which we are aware, the gr/dscf emission limit is not operation specific and can apply to these furnaces at any primary zinc production area source. We have therefore adopted the gr/dscf limit in addition to the proposed lb/hr limit, and sources can meet either the limit expressed in lb/hr or the limit expressed in gr/dscf. E. Basis for Area Source Standards *Comment:*
                         We received a comment from the National Association of Clean Air Agencies (NACAA) expressing concern with EPA's establishment of area source standards under section 112 of the CAA by adopting existing Federal and/or State area source standards. In the comment, the NACAA stated that the existence of State and local regulations does not relieve EPA of its obligation to establish area source standards under the CAA. The NACAA expressed concern that some States cannot have requirements more stringent than those of the Federal government and may, therefore, be required to change their regulations of area sources to be consistent with EPA's area source standards. The NACAA stated that, if the permit requirements that make these sources “well controlled” are not contained within the Federal rule, the nonfederal rules could be relaxed. The NACAA further stated that, in the absence of Federal requirements, there would be nothing to prevent “backsliding” by these sources. The NACAA was particularly concerned with EPA's proposed PVC rule, which adopted the part 61 standards for PVC plants. According to the NACAA, the part 61 standards for PVC plants are outdated and inappropriate as a model for GACT. The NACAA submitted with its comment a recommendation for the standards for area sources of PVC plants. The NACAA previously recommended these limits to EPA as the MACT standards for major sources of PVC plants. The NACAA believes the submittal contains valuable information for EPA in developing PVC regulations for area sources as well. *Response:*
                         We have traditionally reviewed operating permits and current standards in the standards development process, and we used this approach in developing the NESHAP for the four area source categories in this final rule. The NACAA did not explain why it would be inappropriate for EPA to adopt existing Federal, State or local standards that EPA has determined to be 
                        ( print page 2940)
                        effective in controlling HAP emissions. Contrary to the commenter's assertions, EPA is setting final area source standards for the four source categories at issue in this rule. The emissions limits and/or work practice standards in each of the four NESHAP in this final rule have been reviewed, determined by EPA to be the appropriate standards for the relevant area source category, and established by EPA in this final rule as the Federal requirements for that category pursuant to section 112 of the CAA. It is conceivable that for those States with laws that preclude the State from issuing regulations that are more stringent than EPA's regulations, a State may need to change its existing area source regulation in response to this final rule. However, the NACAA has not identified any existing State regulation that would require modification in this regard. Further, as previously mentioned, we established the area source standards in this final rule based on GACT, which may or may not be reflected by more stringent State or local requirements. The NACAA also asserted that the part 61 standards for PVC plants are outdated and inappropriate as GACT for area source PVC plants. NACAA's statement was apparently based on the fact that the part 61 standards were issued prior to the 1990 Amendments to the Clean Air Act and were based on risk. However, the fact that these are risk-based standards are not per se evidence that they do not reflect GACT for area sources of PVC plants. We believe that the record supports our determination as to what constitutes GACT for the four categories at issue here. Moreover, we reviewed the information submitted by the commenter that contained their “presumptive” determination of MACT that they issued as guidance to State and local agencies. These recommended limits were based on the best-controlled plants, most if not all of which are major sources.[3]
                        
                         We believe that these recommended limits may represent MACT or something beyond MACT, but we do not believe that they are appropriate for these particular area source categories. As previously mentioned, we have decided to establish the standards for the PVC and Copolymer Production area source category based on GACT. We do not believe that NACAA's recommended limits represent GACT for area sources of PVC plants. Because we expect PVC plants to be operating in accordance with the part 61 standards for PVC plants, we believe that these standards represent a level of control that is generally available and is therefore a reasonable representation of GACT for area sources in this source category. *Comment:*
                         One commenter stated that area source standards are not needed for primary beryllium plants. All of these plants, including major and area sources, are already subject to NESHAP under 40 CFR part 61. In addition, the proposed area source standard will not achieve any reduction in HAP emissions. A second commenter stated that absent EPA's statutory obligation to establish standards for area sources, there would be no need to regulate PVC and copolymer plants because they are already governed by the existing NESHAP. However, the commenter recognizes EPA's obligation to regulate PVC and copolymer area sources and supports the adoption of the part 61 NESHAP as the area source standard. *Response:*
                         The second commenter has captured the issue and provides the response to the first commenter: EPA has a statutory obligation to establish area source NESHAP for primary beryllium plants. F. Compliance Date *Comment:*
                         Two commenters stated that requiring compliance on the date of publication of the final rule in the 
                        **Federal Register**
                         does not allow sufficient time for existing sources to develop a SSM plan. *Response:*
                         We believe that we have addressed the commenter's concern regarding existing sources' abilities to develop SSM plans by the compliance date. With respect to primary copper smelting and primary zinc production area sources, this final rule allows existing sources in these two area source categories to address SSM according to the relevant requirements in their title V permits, which do not require a SSM plan. As previously discussed in our response to the comments on the necessity of the part 63 SSM requirements (section IV.B of this preamble), we have reviewed the SSM requirements in the title V permits for the existing sources of primary copper smelting and primary zinc production area sources and have determined that these provisions are adequate to replace the SSM requirements in the General Provisions, which require a SSM plan. See 40 CFR 63.6(e)(3). We have therefore included in the final NESHAP for primary copper smelting and primary zinc production area sources requirements that are based on these title V permit terms and conditions. To provide flexibility, sources can comply with the SSM requirements specified in this final rule or comply with the provisions contained in the General Provisions at 40 CFR 63.6(e). Accordingly, the existing sources in these two area source categories are not required to develop SSM plans and may instead continue to follow their title V permit requirements regarding SSM. In addition, as previously mentioned, we are not requiring SSM plans and reports in 40 CFR 63.6(e)(3) for area source PVC plants and beryllium production facilities. Because the NESHAP for these source categories in this final rule adopt part 61 standards, which require compliance at all times, specific provisions governing SSM are unnecessary. For all of the reasons stated above, we believe that the concern expressed in this comment has been addressed. V. Statutory and Executive Order Reviews A. Executive Order 12866: Regulatory Planning and Review Under Executive Order 12866 (58 FR 51735, October 4, 1993), this action is a “significant regulatory action” because it may raise novel legal or policy issues. Accordingly, EPA submitted this action to the Office of Management and Budget (OMB) for review under Executive Order 12866, and any changes made in response to OMB recommendations have been documented in the docket for this action. B. Paperwork Reduction Act The NESHAP for Polyvinyl and Copolymers Production Area Sources do not impose any new information collection burden. New and existing plants that are area sources are required to comply with the same testing, monitoring, reporting, and recordkeeping requirements as those in the National Emission Standards for Vinyl Chloride (40 CFR part 61, subpart F), to which these area sources are currently subject, and the information collection requirements in the part 61 NESHAP General Provisions (40 CFR part 61, subpart A), which are incorporated into the NESHAP. The OMB has previously approved the information collection requirements in 40 CFR part 61, subpart F, under the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 
                        *et seq.*
                         and has assigned OMB control number 2060-0071, EPA Information Collection Request (ICR) number 0186.10. A copy of the OMB-approved ICR for the National Emission Standards for 
                        ( print page 2941)
                        Vinyl Chloride may be obtained from Susan Auby, Collection Strategies Division, U.S. EPA (2822T), 1200 Pennsylvania Ave., NW., Washington, DC 20460, by e-mail at

                         or by calling (202) 566-1672. The requirements for primary beryllium production facilities in the NESHAP for Primary Nonferrous Metals Area Sources do not impose any new information collection burden. New and existing plants that are area sources are required to comply with the same testing, monitoring, recordkeeping, and reporting requirements as those in the National Emission Standards for Beryllium (40 CFR part 61, subpart C), to which these area sources are currently subject, and the information collection requirements in the part 61 General Provisions (40 CFR part 61, subpart A), which are incorporated into the NESHAP for these sources. The OMB has previously approved the information collection requirements in 40 CFR part 61, subpart C, under the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 
                        *et seq.*
                         and has assigned OMB control number 2060-0092, EPA ICR number 0193.08. A copy of the OMB-approved ICR for the National Emission Standards for Beryllium may be obtained from Susan Auby, Collection Strategies Division, U.S. EPA (2822T), 1200 Pennsylvania Ave., NW., Washington, DC 20460, by e-mail at 
                        *auby.susan@epa.gov,*
                         or by calling (202) 566-1672. The information requirements in the NESHAP for Polyvinyl Chloride and Copolymers Production Area Sources, Primary Copper Smelting Area Sources, Secondary Copper Smelting Area Sources, and Primary Nonferrous Metals—Zinc, Cadmium, and Beryllium Area Sources have been submitted for approval to OMB under the Paperwork Reduction Act, 44 U.S.C. 3501 
                        *et seq.*
                         The information collection requirements are not enforceable until OMB approves them. The information collection requirements for primary copper smelting and primary zinc production are based on the current title V permitting requirements for existing sources and the information collection requirements in the part 63 General Provisions (40 CFR part 63, subpart A), most of which are incorporated into the NESHAP for new sources. The ICR document includes the burden estimates for all applicable General Provisions. These recordkeeping and reporting requirements are mandatory pursuant to section 114 of the CAA (42 U.S.C. 7414). All information submitted to EPA pursuant to the information collection requirements for which a claim of confidentiality is made is safeguarded according to CAA section 114(c) and the Agency's implementing regulations at 40 CFR part 2, subpart B. The PM testing, monitoring, recordkeeping, and reporting requirements with which existing primary copper smelting and primary zinc smelting area sources must comply are the same as the requirements that are in these facilities' current title V operating permits. The only new information collection requirements that apply to these area sources consist of initial notifications. There are no existing secondary copper smelting facilities, and there are no requirements for existing secondary copper smelting area sources. Any new primary zinc production facility, primary copper smelter, or secondary copper smelter area source is subject to all information collection requirements in the part 63 General Provisions. No costs or burden hours are estimated for new primary copper smelters, secondary copper smelters, or primary zinc production area sources because no new sources are estimated during the 3-year period of the ICR. No new sources have been constructed in more than 10 years, no new construction has been announced, and we have no indication there will be any new sources in the next 3 years. The annual burden for this information collection (including all four source categories) averaged over the first 3 years of this ICR is estimated to total 23 labor hours per year at a cost of $1,948 for the three existing primary copper smelting area sources and 15.4 labor hours per year at a cost of $1,305 for the two existing primary zinc smelting area sources. No capital/startup costs or operation and maintenance costs are associated with the requirements. Burden means the total time, effort, or financial resources expended by persons to generate, maintain, retain, disclose, or provide information to or for a Federal agency. This includes the time needed to review instructions; develop, acquire, install, and utilize technology and systems for the purposes of collecting, validating, and verifying information, processing and maintaining information, and disclosing and providing information; adjust the existing ways to comply with any previously applicable instructions and requirements; train personnel to be able to respond to a collection of information; search data sources; complete and review the collection of information; and transmit or otherwise disclose the information. An agency may not conduct or sponsor, and a person is not required to respond to, a collection of information unless it displays a currently valid OMB control number. The OMB control numbers for EPA's regulations in 40 CFR part 63 are listed in 40 CFR part 9. When this ICR is approved by OMB, the Agency will publish a technical amendments for the approved information collection requirements contained in the final rules. C. Regulatory Flexibility Act The Regulatory Flexibility Act (RFA) generally requires an agency to prepare a regulatory flexibility analysis of any rule subject to notice and comment rulemaking requirements under the Administrative Procedure Act or any other statute unless the agency certifies that the rule would not have a significant economic impact on a substantial number of small entities. Small entities include small businesses, small not-for-profit enterprises, and small governmental jurisdictions. For the purposes of assessing the impacts of the area source NESHAP on small entities, small entity is defined as: (1) A small business that meets the Small Business Administration size standards for small businesses at 13 CFR 121.201 (less than 1,000 employees for primary copper smelting and less than 750 employees for PVC and copolymers production, secondary copper smelting, and primary nonferrous metals manufacturing); (2) a small governmental jurisdiction that is a government of a city, county, town, school district, or special district with a population of less than 50,000; and (3) a small organization that is any not-for-profit enterprise which is independently owned and operated and is not dominant in its field. After considering the economic impacts of these final rules on small entities, I certify that this action will not have a significant economic impact on a substantial number of small entities. The small entities directly regulated by these final rules are small businesses. We have determined that existing small businesses in these area source categories will not incur any adverse impacts on existing area sources of PVC and copolymer production facilities, primary copper smelters, and non-ferrous metal production facilities because the rules do not create any new requirements or burdens other than minimal notification requirements. There will be no adverse impacts on existing secondary copper area sources because there are no existing sources in the category. Although these final NESHAP contain emission control 
                        ( print page 2942)
                        requirements for new area sources in all four source categories, we are not aware of any new sources being constructed now or planned in the near future, and consequently, we did not estimate any impacts for new sources. Although this final rule will not have a significant economic impact on a substantial number of small entities, EPA nonetheless has tried to reduce the impact of this rule on small entities. These final rules are designed to harmonize with existing State or local requirements. In addition, we have deleted the proposed requirements for SSM plans and reports. D. Unfunded Mandates Reform Act Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), Public Law 104-4, establishes requirements for Federal agencies to assess the effects of their regulatory actions on State, local, and tribal governments and the private sector. Under section 202 of the UMRA, EPA generally must prepare a written statement, including a cost-benefit analysis, for proposed and final rules with “Federal mandates” that may result in expenditures by State, local, and tribal governments, in the aggregate, or to the private sector, of $100 million or more in any 1 year. Before promulgating an EPA rule for which a written statement is needed, section 205 of the UMRA generally requires EPA to identify and consider a reasonable number of regulatory alternatives and adopt the least costly, most cost-effective, or least burdensome alternative that achieves the objectives of the rule. The provisions of section 205 do not apply when they are inconsistent with applicable law. Moreover, section 205 allows EPA to adopt an alternative other than the least costly, most cost-effective, or least burdensome alternative if the Administrator publishes with the final rule an explanation why that alternative was not adopted. Before EPA establishes any regulatory requirements that may significantly or uniquely affect small governments, including tribal governments, it must have developed under section 203 of the UMRA a small government agency plan. The plan must provide for notifying potentially affected small governments, enabling officials of affected small governments to have meaningful and timely input in the development of EPA regulatory proposals with significant Federal intergovernmental mandates, and informing, educating, and advising small governments on compliance with the regulatory requirements. EPA has determined that the final rules do not contain a Federal mandate that may result in expenditures of $100 million or more for State, local, and tribal governments, in the aggregate, or the private sector in any one year. The estimated expenditures for the private sector in any one year are less than $2,500. Thus, the final rules are not subject to the requirements of sections 202 and 205 of the UMRA. In addition, the final rules do not significantly or uniquely affect small governments. The final rules contain no requirements that apply to such governments, impose no obligations upon them, and will not result in expenditures by them of $100 million or more in any one year or any disproportionate impacts on them. Therefore, the final rules are not subject to section 203 of the UMRA. E. Executive Order 13132: Federalism Executive Order 13132 (64 FR 43255, August 10, 1999) requires EPA to develop an accountable process to ensure “meaningful and timely input by State and local officials in the development of regulatory policies that have federalism implications.” “Policies that have federalism implications” are defined in the Executive Order to include regulations that have “substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.” These final rules do not have federalism implications. They will not have substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132. These final rules impose requirements on owners and operators of specified area sources and not State and local governments. Thus, Executive Order 13132 does not apply to these final rules. F. Executive Order 13175: Consultation and Coordination With Indian Tribal Governments Executive Order 13175 (65 FR 67249, November 6, 2000), requires EPA to develop an accountable process to ensure “meaningful and timely input by tribal officials in the development of regulatory policies that have tribal implications.” These final rules do not have tribal implications, as specified in Executive Order 13175. They will not have substantial direct effects on tribal governments, on the relationship between the Federal government and Indian tribes, or on the distribution of power and responsibilities between the Federal government and Indian tribes, as specified in Executive Order 13175. These final rules impose requirements on owners and operators of specified area sources and not tribal governments. Thus, Executive Order 13175 does not apply to these final rules. G. Executive Order 13045: Protection of Children From Environmental Health and Safety Risks Executive Order 13045 (62 FR 19885, April 23, 1997) applies to any rule that: (1) Is determined to be “economically significant,” as defined under Executive Order 12866, and (2) concerns an environmental health or safety risk that EPA has reason to believe may have a disproportionate effect on children. If the regulatory action meets both criteria, EPA must evaluate the environmental health or safety effects of the planned rule on children, and explain why the planned regulation is preferable to other potentially effective and reasonably feasible alternatives considered by EPA. EPA interprets Executive Order 13045 as applying only to those regulatory actions that are based on health or safety risks, such that the analysis required under section 5-501 of the Executive Order has the potential to influence the regulation. These final rules are not subject to the Executive Order. They are based on control technology and not on health or safety risks. H. Executive Order 13211: Actions That Significantly Affect Energy Supply, Distribution, or Use These final rules are not a “significant energy action” as defined in Executive Order 13211 (66 FR 28355, May 22, 2001) because they are not likely to have a significant adverse effect on the supply, distribution, or use of energy. Further, we have concluded that these final rules are not likely to have any adverse energy effects because energy requirements would remain at existing levels. No additional pollution controls or other equipment that consume energy are required by these final rules. I. National Technology Transfer Advancement Act Section 12(d) of the National Technology Transfer and Advancement Act (NTTAA) of 1995 (Pub. L. 104-113, section 12(d), 15 U.S.C. 272 note) directs EPA to use voluntary consensus standards (VCS) in its regulatory activities, unless to do so would be inconsistent with applicable law or otherwise impractical. The VCS are technical standards (
                        *e.g.*, materials specifications, test methods, sampling procedures, and business practices) that are developed or adopted by VCS 
                        ( print page 2943)
                        bodies. The NTTAA directs EPA to provide Congress, through OMB, explanations when the Agency does not use available and applicable VCS. This rule involves technical standards. The EPA cites the following standards: EPA Methods 1, 1A, 2, 2A, 2C, 2D, 2F, 2G, 3, 3A, 3B, 4, 5, 5D, and 9 in 40 CFR part 60, appendix A; and Performance Specifications 1 and 11 in 40 CFR part 60, appendix B. The search identified one VCS as an acceptable alternative to EPA Method 3B. The method ASME PTC 19.10-1981, “Flue and Exhaust Gas Analyses,” is cited in two of these final rules for its manual method for measuring the oxygen, carbon dioxide, and carbon monoxide content of the exhaust gas. This part of ASME PTC 19.10-1981 is an acceptable alternative to EPA Method 3B. The standard ASTM D6216 (1998), “Standard Practice for Opacity Monitor Manufacturers to Certify Conformance with Design and Performance Specifications,” was designated an acceptable alternative for the design specifications given in EPA's Performance Specification 1. As a result, EPA incorporated ASTM D6216-98 by reference into Performance Specification 1 as the design specifications for opacity monitors in August 2000. The search for emissions measurement procedures identified 13 other VCS. The EPA determined that these 13 standards identified for measuring emissions of the HAP or surrogates subject to emission standards in these final rules were impractical alternatives to EPA test methods for the purposes of the rules. Therefore, EPA does not intend to adopt these standards for this purpose. The reasons for the determinations for the 13 methods are in the docket for these rules. For the methods required or referenced by these rules, a source may apply to EPA for permission to use alternative test methods or alternative monitoring requirements in place of any required testing methods, performance specifications, or procedures under §§ 63.7(f) and 63.8(f) of subpart A of the General Provisions. J. Congressional Review Act The Congressional Review Act, 5 U.S.C. 801, 
                        *et seq.*, as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of Congress and to the Comptroller General of the United States. The EPA will submit a report containing these final rules and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the final rules in the 
                        **Federal Register**
                        . A major rule cannot take effect until 60 days after it is published in the 
                        **Federal Register**
                        . This action is not a “major rule” as defined by 5 U.S.C. 804(2). These final rules will be effective on January 23, 2007. List of Subjects in 40 CFR Part 63 Environmental protection

 Applicability and Compliance Dates § 63.11140
  (a) You are subject to this subpart if you own or operate a plant specified in 40 CFR 61.61(c) that produces polyvinyl chloride (PVC) or copolymers and is an area source of hazardous air pollutant (HAP) emissions.

(1) You must calibrate, maintain and operate a system to continuously measure emissions of particulate matter (PM) from the smelter's main stack. (2) All PM collected by the smelter main stack continuous PM sampling system is reported as PM10
                                 unless you 
                                ( print page 2945)
                                demonstrate to the satisfaction of the permitting authority that, due to an infrequent event, the measured PM contains a large fraction of particles greater than 10 microns in diameter. (3) To determine the mass emissions rate, the PM10
                                 concentration as determined by the smelter main stack continuous PM sampling system is multiplied by the volumetric flow rate for the smelter main stack and any necessary conversion factors. (4) Compliance with the PM10
                                 emissions limit is demonstrated based on the average mass PM10
                                 emissions rate for each 24-hour period. (5) The results of the PM monitoring and calculated average mass PM10
                                 emissions rate for each 24-hour period must be recorded and the records maintained for at least 5 years.

 § 63.11148
  (a) 
                                *Emissions limits and work practice standards.*
                                 (1) For each copper concentrate dryer, you must not discharge to the atmosphere from the dryer vent any gases that contain total particulate matter (PM) in excess of 0.022 grains per dry standard cubic foot (gr/dscf). (2) You must exhaust the process off gas from each smelting vessel to a control device according to the requirements in paragraphs (a)(2)(i) and (ii) of this section. (i) During periods when copper ore concentrate feed is charged to and smelted to form molten copper matte and slag layers in the smelting vessel, you must exhaust the process off gas from the smelting vessel to a gas cleaning system controlling PM and to a sulfuric acid plant prior to discharge to the atmosphere. (ii) During periods when no copper ore concentrate feed is charged to or molten material tapped from the smelting vessel but the smelting vessel 
                                ( print page 2946)
                                remains in operation to temporarily hold molten material in the vessel before resuming copper production, you must exhaust the process off gas from the smelting vessel to an electrostatic precipitator or baghouse prior to discharge to the atmosphere. (3) You must control the process emissions released when tapping copper matte or slag from a smelting vessel according to paragraphs (a)(3)(i) and (ii) of this section. (i) You must operate a capture system that collects the gases and fumes released when copper matte or slag is tapped from the smelting vessel. The design and placement of this capture system must be such that the tapping port opening, launder, and receiving vessel (e.g., ladle, slag pot) are positioned within the confines or influence of the capture system's ventilation draft during those times when the copper matte or slag is flowing from the tapping port opening. (ii) You must not cause to be discharged to the atmosphere from the capture system used to comply with paragraph (a)(3)(i) of this section any gases that contain total PM in excess of 0.022 gr/dscf. (4) For each batch copper converter, you must meet the requirements in paragraphs (a)(4)(i) through (iv) of this section. (i) You must operate a primary capture system that collects the process off gas vented when one or more batch copper converters are blowing. If you operate a batch copper converter that does not use a “U”-shaped side flue located at one end of the converter, then the capture system design must include use of a primary hood that covers the entire mouth of each batch copper converter vessel when the copper converter is positioned for blowing. The capture system may use multiple intake and duct segments through which the ventilation rates are controlled independently of each other. (ii) If you operate a batch copper converter that does not use a “U”-shaped side flue located at one end of the converter, then you must operate a secondary capture system that collects gases and fumes released from the batch copper converter when the converter mouth is rotated out partially or totally from within the confines or influence of the primary capture system's ventilation draft during charging, skimming, pouring, or holding. The capture system design must use additional hoods (e.g., sliding secondary hoods, air curtain hoods) or other capture devices (e.g., building evacuation systems). The capture system may use multiple intake and duct segments through which the ventilation rates are controlled independently of each other, and individual duct segments may be connected to separate PM control devices. (iii) You must exhaust the process off gas captured by the primary capture system that is used to comply with paragraph (a)(4)(i) of this section to a gas cleaning system controlling PM and to a sulfuric acid plant prior to discharge to the atmosphere. (iv) For each secondary capture system that is used to comply with paragraph (a)(4)(ii) of this section and is not vented to a gas cleaning system controlling PM and a sulfuric acid plant, you must not cause to be discharged to the atmosphere any gases that contain total particulate matter in excess of 0.02 grains/dscf. (b) 
                                *Monitoring requirements for electrostatic precipitators.*
                                 To monitor the performance of each electrostatic precipitator used to comply with the PM emissions limits in paragraph (a) of this section, you must use a continuous opacity monitoring system (COMS) that is installed at the outlet of each electrostatic precipitator or a common duct at the outlet of multiple electrostatic precipitators. (1) Each COMS must meet Performance Specification 1 in 40 CFR part 60, appendix B. (2) You must comply with the quality assurance requirements in paragraphs (b)(2)(i) through (v) of this section. (i) You must automatically (intrinsic to the opacity monitor) check the zero and upscale (span) calibration drifts at least once daily. For a particular COMS, the acceptable range of zero and upscale calibration materials is as defined in the applicable version of Performance Specification 1 in 40 CFR part 60, appendix B. (ii) You must adjust the zero and span whenever the 24-hour zero drift or 24-hour span drift exceeds 4 percent opacity. The COMS must allow for the amount of excess zero and span drift measured at the 24-hour interval checks to be recorded and quantified. The optical surfaces exposed to the effluent gases must be cleaned prior to performing the zero and span drift adjustments, except for systems using automatic zero adjustments. For systems using automatic zero adjustments, the optical surfaces must be cleaned when the cumulative automatic zero compensation exceeds 4 percent opacity. (iii) You must apply a method for producing a simulated zero opacity condition and an upscale (span) opacity condition using a certified neutral density filter or other related technique to produce a known obscuration of the light beam. All procedures applied must provide a system check of the analyzer internal optical surfaces and all electronic circuitry including the lamp and photodetector assembly. (iv) Except during periods of system breakdowns, repairs, calibration checks, and zero and span adjustments, the COMS must be in continuous operation and must complete a minimum of one cycle of sampling and analyzing for each successive 10 second period and one cycle of data recording for each successive 6-minute period. (v) You must reduce all data from the COMS to 6-minute averages. Six-minute opacity averages must be calculated from 36 or more data points equally spaced over each 6-minute period. Data recorded during periods of system breakdowns, repairs, calibration checks, and zero and span adjustments must not be included in the data averages. An arithmetic or integrated average of all data may be used. (3) You must evaluate opacity measurements from the COMS on a 24-hour rolling average excluding periods of startup, shutdown, and malfunction. If the 24-hour rolling average opacity exceeds 15 percent, you must initiate investigation of the relevant controls or equipment within 24 hours of the first discovery of the high opacity incident and, if necessary, take corrective action as soon as practicable to adjust or repair the controls or equipment to reduce the opacity average to below the 15 percent level. (4) You must log in ink or electronic format and maintain a record of 24-hour opacity measurements performed in accordance with paragraph (b)(3) of this section and any corrective actions taken, if any. A record of corrective actions taken must include the date and time during which the 24-hour rolling average opacity exceeded 15 percent and the date, time and type of the corrective action. (c) 
                                *Monitoring requirements for baghouses.*
                                 To monitor the performance of each baghouse used to comply with PM emissions limits in paragraph (a) of this section, you must use a bag leak detection system according to the requirements in paragraphs (c)(1) through (4) of this section. (1) You must install, calibrate, maintain, and continuously operate a bag leak detection system for the baghouse to monitor the baghouse performance. (2) The baghouse leak detection system must meet the specifications and requirements in paragraphs (c)(2)(i) through (v) of this section. 
                                ( print page 2947) (i) The bag leak detection system must be certified by the manufacturer to be capable of detecting particulate matter emissions at concentrations that can effectively discern any dysfunctional leaks of the baghouse. (ii) The bag leak detection system sensor must provide output of relative or absolute particulate matter loadings. (iii) The bag leak detection system must be equipped with an alarm system that will sound automatically when an increase in relative particulate emissions over a preset level is detected. The alarm must be located where it is easily heard by plant operating personnel. (iv) The bag leak detection system must be installed downstream of the baghouse. (v) The bag leak detection system must be installed, operated, calibrated, and maintained in a manner consistent with the manufacturer's written specifications and recommendations. The calibration of the system must, at a minimum, consist of establishing the relative baseline output level by adjusting the sensitivity and the averaging period of the device and establishing the alarm set points and the alarm delay time. (3) If the bag leak detection system alarm sounds, you must initiate investigation of the baghouse within 24 hours of the first discovery of the alarm and, if necessary, take corrective action as soon as practicable to adjust or repair the baghouse to minimize possible exceedances of the applicable PM emissions limits in paragraph (a) of this section. (4) You must log in ink or electronic format and maintain a record of installation, calibration, maintenance, and operation of the bag leak detection system. If the bag leak detection system alarm sounds, the records must include an identification of the date and time of all bag leak detection alarms, their cause, and an explanation of the corrective actions taken, if any. (d) 
                                *Alternative monitoring requirements for baghouses.*
                                 As an alternative to the requirements in paragraph (c) of this section for bag leak detection systems, you must monitor the performance of each baghouse used to comply with a PM emissions limit in paragraph (a) of this section using a COMS that is installed at the outlet on the baghouse or a common duct at the outlet of multiple baghouses. Each COMS must meet the requirements in paragraphs (b)(1) through (4) of this section. (e) 
                                *Performance testing.*
                                 (1) You must demonstrate initial compliance with the applicable PM emissions limits in paragraph (a) of this section based on the results of a performance test for each affected source.

                             Under section 112(a) of the Clean Air Act, an area source is defined as a stationary source that is not a major source. A major source is defined as a stationary source or a group of stationary sources located within a contiguous area and under common control that emits or has the potential to emit considering controls, in the aggregate, 10 tons per year or more of any HAP or 25 tons per year or more of any combination of HAP.

                             In 1995, the Court of Appeals for the District of Columbia Circuit reviewed the definition of “potential to emit” (PTE) contained in 40 CFR in 40 CFR 63.2 (
                            *National Mining Ass'n*
                             v. 
                            *EPA*, 59 F.3d 1351 (D.C. Cir. 1995)). In July 2005, the D.C. Circuit remanded the definition to EPA to the extent the definition required that physical or operational limitations be “federally enforceable” (
                            *National Mining Ass'n*
                             v. 
                            *EPA*, 59 F.3d 1351 (D.C. Cir. 1995)). The court did not vacate the 40 CFR part 63 regulations and therefore the definition of “potential to emit” in 40 CFR part 63 remains in place. EPA is currently in the process of developing a proposed rule that responds to the court's remand. EPA has a transitional policy that relates to PTE. See “Options for Limiting the Potential to Emit (PTE) of a Stationary Source Under Section 112 and Title V of the Clean Air Act (Act)” (Jan. 25, 1995), available at 
                            *http://www.epa.gov/​Region7/​programs/​artd/​air/​title5/​t5memos/​ptememo.pdf*. EPA has extended the transition policy several times. See “Third Extension of January 25, 1995 Potential to Emit Transition Policy” (December 20, 1999), available at 
                            *http://www.epa.gov/​Region7/​programs/​artd/​air/​title5/​t5memos/​4thext.pdf*. Under the Third Extension, sources can rely on State-only enforceable PTE limits until we finalize our response to the remand. Back to Citation
