On April 14, 2003, pursuant to section 112 of the Clean Air Act (CAA), the EPA issued national emission standards to control hazardous air pollutants emitted from pushing, quenching, and battery stacks at new and existing coke oven batteries. This action amends the parametric operating limits and associated compliance provisions for capture systems used to control emissions from pushing. This action also amends the requirements for mobile scrubber cars that capture emissions which occur during pushing and travel.

This table is not intended to be exhaustive, but rather provides a guide for readers regarding entities likely to be regulated by this action. To determine whether your facility would be regulated by this action, you should examine the applicability criteria in § 63.7281 of the national emission standards for hazardous air pollutants (NESHAP) for coke ovens: Pushing, quenching, and battery stacks. If you have any questions regarding the applicability of this action to a particular entity, consult the person listed in the preceding FOR FURTHER INFORMATION CONTACT section.
In addition to being available in the docket, an electronic copy of today's final amendments is also available on the Worldwide Web (WWW) through the Technology Transfer Network (TTN). Following the Administrator's signature, a copy of the final amendments will be placed on the TTN's policy and guidance page for newly proposed or promulgated rules at http://www.epa.gov/​ttn/​oarpg. The TTN provides information and technology exchange in various areas of air pollution control. If more information regarding the TTN is needed, call the TTN HELP line at (919) 541-5384.
Under section 307(b)(1) of the CAA, judicial review of the final amendments is available only by filing a petition for review in the U.S. Court of Appeals for the District of Columbia Circuit by December 13, 2004. Under section 307(d)(7)(B) of the CAA, only an objection to the final amendments 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 the final amendments may not be challenged separately in any civil or criminal proceedings brought by the EPA to enforce these requirements.
We are publishing the amendments as a direct final rule without prior proposal because we view the amendments as noncontroversial and do not anticipate adverse comments. However, in the Proposed Rules section of this Federal Register, we are publishing a separate document that will serve as the proposal for the amendments contained in the direct final rule in the event that significant adverse comments are filed. If we receive any significant adverse comments on one or more distinct amendments, we will publish a timely withdrawal in the Federal Register informing the public which provisions will become effective and which provisions are being withdrawn due to adverse comment. We will address all public comments in a subsequent final rule based on the proposed rule (should we decide to issue a final rule). We will not institute a second comment period on the direct final rule. Any parties interested in commenting must do so at this time.
A. What changes are we making as a result of the settlement agreement?
On April 14, 2003 (68 FR 18008), we issued national emission standards for the control of hazardous air pollutants (HAP) from pushing, quenching, and battery stacks at new and existing coke oven batteries (40 CFR part 63, subpart CCCCC). The NESHAP implements section 112(d) of the CAA by requiring all major sources to meet HAP emission standards reflecting application of the maximum achievable control technology (MACT).[1]
After publication of the final rule, the American Iron and Steel Institute (AISI)/American Coke and Coal Chemicals Institute (ACCCI) Coke Oven Environmental Task Force (COETF) filed a petition for review challenging the final standards (AISI/ACCCI Coke Oven Environmental Task Force v. U.S. Environmental Protection Agency, no. 03-1167, D.C. Cir.). The petitioners raised issues concerning:
The provisions requiring owners or operators of coke plants having a pushing emission control device to install, operate and maintain devices to monitor daily average fan motor amps, (or volumetric flow rate at the inlet of the control device and maintain daily average volumetric flow rate) at or above minimum levels established during initial performance tests. These provisions are included in 40 CFR 63.7290, 63.7323(c), 63.7326(a)(4), Start Printed Page 6081563.7330(d), 63.7331(g) and (h), and 63.7333(d).
The EPA and the petitioners anticipate that certain amendments to the final rule will resolve COETF's concerns. These amendments are set out in attachment A to a proposed settlement agreement between EPA and COETF. In accordance with section 113(g) of the CAA, EPA published a notice of the proposed settlement agreement (69 FR 31372, June 3, 2004) and provided a 30-day comment period which ended July 6, 2004. The EPA received no comments on the proposed settlement agreement. Under the terms of the proposed settlement agreement, EPA must submit proposed amendments for publication in the Federal Register within 90 days after review of public comments received in response to the notice of the settlement agreement. Within 120 days after the close of the comment period on the proposal, EPA must submit for publication in the Federal Register a notice setting forth the Administrator's final decision on the issues covered by the proposal.
Concurrent with development of the proposed settlement agreement, a coke manufacturer constructing a new non-recovery plant noticed a gap in the promulgated rule. The new source is being constructed with a type of emission control system that is not addressed in the final rule. Therefore, the source requested EPA to develop an appropriate emission limit for that control system. In response, we are broadening the applicability of an existing emissions limit to include the control system and are adding appropriate implementation and compliance provisions.
The petitioners argued that the operating limit in 40 CFR 63.7290(3)(i) of the final rule for capture systems applied to pushing emissions (which requires the plant to maintain the daily average fan motor amperage at or above a certain level) was inappropriate for systems that did not use an electric motor to drive the fan. We agree with the petitioners because there are a few fans that are not powered by an electric motor. In response, we are amending the operating limit in 40 CFR 63.7290(b)(3)(i) to state that the requirement applies to capture systems that use an electric motor to drive the fan. We are adding a new operating limit in 40 CFR 63.7290(b)(3)(ii) that is appropriate for assessing the proper operation of a capture system that does not use an electric motor to drive the fan. The new operating limit requires the owner or operator to maintain the daily average static pressure at the inlet to the control device at an equal or greater vacuum than the level established during the initial performance test, or to maintain the daily average fan revolutions per minute (RPM) at or above the minimum level established during the initial performance test. We also renumbered the existing operating limit for the daily average volumetric flow rate in 40 CFR 63.7290(b)(3)(ii) as 40 CFR 63.7290(b)(3).
We also are adding requirements to the final rule for demonstrating initial and continuous compliance with the new operating limit for daily average static pressure or fan RPM. To establish the operating limit, a new procedure in 40 CFR 63.7323(c)(3) requires that the static pressure at the inlet of the control device or fan RPM during each push sampled for each particulate matter (PM) test run during the performance test be measured and recorded. The operating limit for static pressure is the minimum vacuum recorded during any of the three runs that meets the emission limit. The operating limit for fan RPM is the lowest RPM recorded during any of the three runs that meets the emission limit. To demonstrate initial compliance, a new provision in 40 CFR 63.7326(a)(4) requires that the owner or operator have a record of the static pressure at the inlet of the control device or fan RPM measured during the performance test. To demonstrate continuous compliance, 40 CFR 63.7330(d) requires the owner or operator to monitor the static pressure or the fan RPM at all times according to the requirements in 40 CFR 63.7331(i), which requires a device to measure static pressure at the inlet of the control device or the fan RPM. A new provision in 40 CFR 63.7333(d) requires the owner or operator to maintain the daily average static pressure at the inlet to the control device at an equal or greater vacuum than established during the initial or subsequent performance test, or to maintain the daily average fan RPM at or above the minimum level established during the initial or subsequent performance test. The owner or operator also must check the static pressure or fan RPM at least every 8 hours to verify the daily average static pressure at the inlet to the control device, or the daily average fan RPM, is at or above the required values and to record the results of each check. We also made conforming amendments in each of the affected sections to account for changes in the regulatory citations.
The petitioners also argued that the provision in 40 CFR 63.7300(c)(1), which requires that the operation and maintenance plan include requirements to repair any defect or deficiency in the capture system before the next scheduled inspection, is unreasonable. We agree because there are a few repairs that may require more than 30 days to complete. Therefore, we are replacing the provision to complete all repairs within 30 days after the defect or deficiency is found to allow more time when necessary. If the repairs cannot be completed within 30 days, the owner or operator must estimate the number of days in which repairs can be completed. We developed provisions for two additional situations (i.e., one for repairs that can be made within 60 days and one for repairs that will take longer than 60 days).
If repairs can be completed within 60 days from the date that the problem is discovered, the owner or operator must submit a written notice to the permitting authority within 30 days after the date that the problem is discovered. The notice must contain specific information, including a description of the defect or deficiency, the steps needed to correct the problem, the interim steps needed to mitigate the emissions impact of the defect or deficiency, and an explanation of why the repairs cannot be completed within 30 days from the date that the problem is discovered.
If the repairs cannot be completed within 60 days, the owner or operator must submit a written request to the permitting authority for an extension of time to complete the repairs. The owner or operator must submit this request to the permitting authority within 45 days after the date the defect or deficiency is discovered. The amendments require that this request include the information required for the previous notice, along with a detailed proposed schedule for completing the repairs and a request for approval of the proposed repair schedule. The permitting authority may consider all relevant factors in deciding whether to approved or deny the Start Printed Page 60816request, including feasibility and safety, and may request modifications to the proposed schedule. If the permitting authority approves the request, the approved schedule must provide for completion of repairs as soon as practicable. This new requirement provides flexibility for unforeseen circumstances but also requires accountability for making needed repairs.
A new non-recovery coke plant now under construction will use flat car pushing along with a mobile control system (closed hood capture system vented to a multicyclone) to control PM emissions during pushing and travel to the quench tower. There are no test data for the proposed control system because no such system has been built. Consequently, we cannot develop an alternative emissions limit. However, the existing emission limit of 0.04 pound per ton of coke in 40 CFR 63.7290(a)(4), which applies to mobile scrubber cars that capture emissions during travel, covers a comparable situation. Therefore, we are changing the applicability of the limit from “mobile scrubber car” to “mobile control device.” Thus, the existing limit will apply to any type of mobile control device applied to pushing emissions that also captures emissions during travel at a new or existing coke oven battery.
While the existing rule contains monitoring provisions for scrubbers, baghouse, and capture systems, it does not include requirements applicable to multicyclones. Therefore, we have added an operating limit to the final rule, along with requirements for demonstrating initial and continuous compliance. Based on information in EPA's 1998 “Compliance Assurance Monitoring Technical Guidance Document” (available at http://www.epa.gov/​ttn/​emc/​cam), we selected pressure drop as the indicator of proper control device performance. For multicyclones, control efficiency is a function of inlet velocity, and changes in velocity result in changes in pressure drop across the device. If the inlet velocity exceeds a certain level, turbulence becomes excessive and control efficiency decreases. Therefore, the operating limit requires the owner or operator to maintain the pressure drop at or below the level established during the initial performance test. A continuous parameter monitoring system (CPMS) is required to measure and record the pressure drop across the device. We also added rule provisions for establishing an operating limit; demonstrating initial compliance; installing, operating, and maintaining the CPMS; and demonstrating continuous compliance with the parametric operating limit.
This action does not impose any new information collection burden. The costs of the information collection requirements associated with the provisions related to the settlement agreement do not increase the existing burden estimates for the final rule. The OMB has previously approved the information collection requirements contained in the existing rule (40 CFR part 63, subpart CCCCC) under the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. and has assigned OMB control number 2060-0521, EPA ICR number 1995.02. A copy of the approved Information Collection Request (ICR) may be obtained from Susan Auby, Collection Strategies Division, U.S. Environmental Protection Agency (2822T), 1200 Pennsylvania Ave., NW., Washington, DC 20460 or by calling (202) 566-1672.
For the purposes of assessing the impacts of today's final amendments on small entities, small entity is defined as: (1) A small business having no more than 1,000 employees, as defined by the Small Business Administration for NAICS codes 331111 and 324199; (2) a government 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 that is not dominant in its field.
After considering the economic impacts of today's final amendments on small entities, the EPA has concluded that this action will not have a significant economic impact on a substantial number of small entities. In determining whether a rule has a significant economic impact on a substantial number of small entities, the impact of concern is any significant adverse economic impact on small Start Printed Page 60817entities, since the primary purpose of the regulatory flexibility analyses is to identify and address regulatory alternatives “which minimize any significant economic impact of the proposed rule on small entities” (5 U.S.C. 603 and 604). Thus, an agency may conclude that a rule will not have a significant economic impact on a substantial number of small entities if the rule relieves regulatory burden, or otherwise has a positive economic effect on all of the small entities subject to the rule.
We believe there will be a positive impact on small entities because the final rule amendments add new compliance provisions to increase flexibility. These changes are voluntary and do not impose new costs. We have, therefore, concluded that today's final rule amendments will relieve regulatory burden for all small entities.
The EPA has determined that the final amendments 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 to the private sector in any 1 year. No new costs are attributable to the final amendments. Thus, the final rule amendments are not subject to the requirements of sections 202 and 205 of the UMRA. The EPA has also determined that the final rule amendments contain no regulatory requirements that might significantly or uniquely affect small governments because they contain no requirements that apply to such governments or impose obligations upon them. Therefore, the final rule amendments are not subject to section 203 of the UMRA.
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.” The final rule amendments do not have tribal implications, as specified in Executive Order 13175, because tribal governments do not own or operate any sources subject to the final rule amendments. Thus, Executive Order 13175 does not apply to the final rule amendments.
As noted in the proposed amendments, Section 112(d) of the National Technology Transfer and Advancement Act (NTTAA) of 1995 (Pub. L. 104-113; 15 U.S.C 272 note) directs the EPA to use voluntary consensus standards in their regulatory and procurement activities unless to do so would be inconsistent with applicable law or otherwise impracticable. Voluntary consensus standards are technical standards (e.g., material specifications, test methods, sampling procedures, business practices) developed or adopted by one or more voluntary consensus bodies. The NTTAA requires EPA to provide Congress, through the OMB, Start Printed Page 60818explanations when the Agency decides not to use available and applicable voluntary consensus standards.
The EPA's compliance with section 112(d) of the NTTAA has been addressed in the preamble to the existing rule (68 FR 18025, April 14, 2003). The final rule amendments do not involve technical standards. Therefore, EPA is not considering the use of any voluntary consensus standards.
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 the Congress and to the Comptroller General of the United States. The EPA will submit a report containing this rule 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 rule in the Federal Register. This action is not a “major rule” as defined by 5 U.S.C. 804(2). The final rule amendments will be effective on January 11, 2005.

You must then complete the repairs within 60 days after the date that the defect or deficiency is discovered.
(ii) In those rare instances when repairs cannot be completed within 60 days, you must submit a written request for extension of time to complete the repairs. The request must be received by the permitting authority not more than 45 days after the date that the defect or deficiency is discovered. The request must contain all of the information required for the written notice described in paragraph (c)(1)(i) of this section, along with a detailed proposed schedule for completing the repairs and a request for approval of the proposed repair schedule. The permitting authority may consider all relevant factors in deciding whether to approve or deny the request (including feasibility and safety). Each approved schedule must provide for completion of repairs as expeditiously as practicable, and the permitting authority may request modifications to the proposed schedule as part of the approval process.

(h) For each multicyclone applied to pushing emissions and subject to the operating limit in § 63.7290(b)(4), you must demonstrate compliance by meeting the requirements in paragraphs (h)(1) through (3) of this section.
(1) Maintaining the daily average pressure drop at a level at or below the level established during the initial or subsequent performance test.
(2) Operating and maintaining each CPMS according to § 63.7331(k) and recording all information needed to document conformance with these requirements.
(3) Collecting and reducing monitoring data for pressure drop according to § 63.7331(e)(1) through (3).
1. The final rule should not be confused with the MACT standards for coke oven doors, lids, offtake systems, and charging which are the subject of special statutory provisions (CAA section 112(d)(8), 112(i)(8)). The EPA adopted MACT standards for those emission points in 1993 (58 FR 57898, October 27, 1993), and recently proposed residual risk standards pursuant to CAA section 112(f)(2) for these sources (69 FR 68338, August 9, 2004).
