NESHAP: National Emission Standards for Hazardous Air Pollutants: Standards for Hazardous Waste Combustors; Amendments, 18970-18984 [E8-6667]

Download as PDF 18970 Federal Register / Vol. 73, No. 68 / Tuesday, April 8, 2008 / Rules and Regulations EPA is publishing this rule without prior proposal because the Agency views this as a noncontroversial amendment and anticipates no adverse comments. This action simply reflects already existing Federal requirement for state air pollution control agencies and existing LMWC units that are subject to the provisions of 40 CFR part 60, subpart Cb and related subpart Eb. However, in the ‘‘Proposed Rules’’ section of today’s Federal Register, EPA is publishing a separate document that will serve as the proposal to approve the section 111(d)/129 plan revision should relevant adverse or critical comments be filed. This rule will be effective June 9, 2008 without further notice unless EPA receives adverse comments by May 8, 2008. If EPA receives adverse comments, EPA will publish a timely withdrawal in the Federal Register informing the public that the rule did not take effect. EPA will address all public comments in a subsequent final rule based on the proposed rule. The EPA will not institute a second comment period on this action. Any parties interested in commenting must do so at this time. rwilkins on PROD1PC63 with RULES IV. Statutory and Executive Order Reviews Under the Clean Air Act, the Administrator is required to approve a 111(d)/129 plan submission that complies with the provisions of the Act and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing 111(d)/129 plan submissions, EPA’s role is to approve state choices, provided that they meet the criteria of the Clean Air Act. Accordingly, this action merely approves state law as meeting Federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this action: • Is not a ‘‘significant regulatory action’’ subject to review by the Office of Management and Budget under Executive Order 12866 (58 FR 51735, October 4, 1993); • Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.); • Is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.); • Does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104–4); VerDate Aug<31>2005 16:20 Apr 07, 2008 Jkt 214001 • Does not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999); • Is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997); • Is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001); • Is not subject to requirements of Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the Clean Air Act; and • Does not provide EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994). In addition, this rule does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because the 111(d)/ 129 plan is not approved to apply in Indian country located in the state, and EPA notes that it will not impose substantial direct costs on tribal governments or preempt tribal law. 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. EPA will submit a report containing this action 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. 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). Under section 307(b)(1) of the Clean Air Act, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by June 9, 2008. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this action for the purposes of judicial review nor does it extend the time within which a petition for judicial review may be filed, and shall not postpone the effectiveness of such rule or action. This action may not be challenged later in proceedings to PO 00000 Frm 00028 Fmt 4700 Sfmt 4700 enforce its requirements. (See section 307(b)(2).)

What Is the Source of Authority for the Development of NESHAP? Section 112(c) of the Clean Air Act requires EPA to list categories and subcategories of major sources and area sources of hazardous air pollutants (HAP) and to establish NESHAP for the listed source categories and subcategories. Hazardous waste combustors include incinerators, cement kilns, lightweight aggregate kilns, boilers, and hydrochloric acid production furnaces that burn hazardous waste. EPA’s initial list of categories of major and area sources of HAP was published on July 16, 1992 (57 FR 31576). Hazardous waste incinerators, Portland cement manufacturing, clay products manufacturing (including lightweight aggregate kilns), industrial/commercial/ institutional boilers and process heaters, and hydrochloric acid production furnaces were among the listed categories of sources. Major sources of HAP are those sources that have the potential to emit at least 10 tons per year of any one HAP or 25 tons per year of any combination of HAP. B. How Did the Public Participate in Developing the Amendments to the Final Rule? The final rule was published on October 12, 2005 (70 FR 59402) and codified in 40 CFR part 63, subpart EEE. Following publication of the final rule, two industry trade associations identified a number of typographical errors and suggested several potential compliance and monitoring amendments and clarifications to the rule.1 On September 6, 2006, we published proposed amendments (71 FR at 52639) to address these issues and sought public comment on the proposed amendments.2 EPA received comments from five entities. Today’s action presents EPA’s responses to those comments and promulgates amendments to Subpart EEE of 40 CFR part 63. II. Summary of the Final Amendments In today’s notice, we are announcing our final action on several amendments to Subpart EEE of 40 CFR part 63. The amendments revise several compliance and monitoring provisions in response to questions and issues raised by entities affected by the rule. The revised provisions are effective immediately, and today’s final rule does not change the October 14, 2008 compliance date established by the October 12, 2005 final rule. See also Section III (Time Lines for compliance activities) in today’s action. Sources can readily comply with the revised provisions promulgated today within the compliance time frames established by the October 12, 2005 final rule. See § 63.1206(a). A. Proposed Amendments for Which No Adverse Comments Were Received In the September 6, 2006 proposal, we proposed several corrections and clarifications to the NESHAP for hazardous waste combustors. 71 FR at 52639–642, 52645–646. We received no adverse comments on the majority of the corrections and clarifications (see Table 1 below). Therefore, we are promulgating those provisions, as proposed, without further discussion.3 The reader is referred to the September 2006 proposed rule for background on these changes.

The other issues related to our response to four petitions for reconsideration that were submitted to the Administrator pursuant to section 307(d)(7)(B) of the Clean Air Act.

Nor does this final rule address any of the issues raised by EPA’s solicitation of comment published on September 27, 2007 (72 FR 54875). 3 Please note, however, that we have revised proposed § 63.1207(d)(2), which prescribes the schedule for confirmatory performance testing, to PO 00000 Frm 00030 Fmt 4700 Sfmt 4700 conform with existing § 63.1207(b)(3) to clarify further that confirmatory performance testing is not required for sources that are not subject to a numerical D/F emission standard: solid fuel boilers and hydrochloric acid production furnaces; lightweight aggregate kilns that are not subject to a numerical dioxin/furan emission standard under § 63.1221; and liquid fuel boilers that are not subject to a numerical dioxin/furan emission standard under § 63.1217.

None. Interpretation of existing regulations (see 71 FR at 52646). We also received no adverse comment on the proposed amendments described in Section V.G (Calculating Rolling Averages for Averaging Periods in Excess of 12 Hours) of the September 6, 2006 preamble citation. That discussion described our intent to simplify the monitoring requirements for sources that select mercury or semivolatile metal feedrate limits averaged over periods greater than 12 hours. As described in the preamble, this would require identical changes to four paragraphs of the regulation: §§ 63.1209(n)(2)(v)(A)(2)(iv), 63.1209(n)(2)(v)(A)(3)(v), 63.1209(l)(1)(ii)(B)(5), and 63.1209(l)(1)(ii)(C)(5). However, corresponding regulatory changes to the latter three paragraphs were inadvertently omitted from the September 2006 proposed rule. In today’s rule, we are correcting this oversight by promulgating the language proposed for § 63.1209(n)(2)(v)(A)(2)(iv) in all four paragraphs. B. Proposed Amendments for Which Comments Were Received rwilkins on PROD1PC63 with RULES 1. Calculating Rolling Averages a. Summary of the Final Action. We are revising §§ 63.1209(n)(2)(v)(B)(1), 63.1209(n)(2)(v)(B)(2), and 63.1209(o)(1)(ii)(A)(3) as proposed on September 6, 2006. 71 FR at 52640. These changes are intended to clarify that data for demonstrating compliance with feed rate limits of up to a 12-hour rolling average must be updated each minute. In addition, § 63.1209(n)(2)(v)(B)(1)(i) is modified to confirm that the chromium feed rate limit for boilers burning liquid hazardous waste with a heating value of 10,000 Btu/lb or greater is a 12-hour rolling average limit. b. What Are the Responses to Major Comments? Comment: We received two comments on this topic. One supported the changes as proposed. The other commenter objected to updating the 12hour average every minute rather than every hour, arguing that this VerDate Aug<31>2005 16:20 Apr 07, 2008 Jkt 214001 complicates data management and could require increased data storage. Response: We believe that complications to data management or increases in data storage requirements, if any, are negligible. Phase I sources— incinerators, cement kilns, and lightweight aggregate kilns—have been complying with 12-hour averages updated each minute for several years without significant problems. Furthermore, data storage is not measurably affected. These continuous monitors are required to record a data point at least once each minute, regardless of the whether the rolling average value for determining compliance is updated each minute or each hour. Consequently, the amount of recorded data is not significantly affected under either approach to calculating the rolling average. Phase I sources have been required to update their 12-hour rolling average feed rate data each minute ever since the hazardous waste combustor MACT rule was first promulgated in 1999. A ‘‘rolling average’’ was defined in that rule as ‘‘the average of all one-minute averages over the averaging period.’’ That definition has remained the same through the interim standards (for Phase I sources) and the replacement standards. We have consistently interpreted the definition to require that a new rolling average be calculated each minute. See, for example, the preamble discussion in the September 30, 1999 rule which says, while discussing how to calculate rolling averages upon initial startup, ‘‘Given that the one-hour, and 12-hour rolling averages for limits on various parameters must be updated each minute * * *’’ 64 FR at 52924. In the 2004 replacement standards proposed rule, we first introduced the concept of hourly updates to rolling averages, but only in the context of monitoring compliance with annual rolling average feed rate limits. See 69 FR at 21312. At no time did we discuss or propose any change to the longstanding requirement that rolling averages of 12 hours or less be updated each minute. In fact, we reiterated the PO 00000 Frm 00031 Fmt 4700 Sfmt 4700 requirement for one-minute updates in discussing how compliance with the 12hour thermal feed rate limits would be monitored. In that discussion we said that ‘‘For compliance, you would continuously monitor the feed rate of hazardous waste on a 12-hour rolling average updated each minute or, for standards based on normal emissions, on an annual rolling average updated each hour.’’ Id. at 21312. Given that we have consistently required rolling averages of 12 hours or less to be updated each minute and we have never discussed or proposed any changes to that approach, we find ample evidence that the addition of hourly updates for these parameters in the final replacement standards were, as we asserted in the proposed rule, inadvertent. Furthermore, we find no support for the commenter’s claim that data management or data storage requirements are significantly affected under either approach. Therefore, we have removed the references to hourly updates, as proposed. 2. Expressing Particulate Matter Standards Using the International System of Units a. Summary of the Final Action. We proposed to revise the particulate matter standards expressed in English units (gr/dscf) in §§ 63.1216 through 63.1221 by converting and expressing the standards using the International System of Units (SI). 71 FR at 52641. However, after considering the comments received in response to the proposed rule, we are not revising the standards as proposed. Thus, we are retaining the format of the particulate matter standards as promulgated in the October 12, 2005 final rule. b. What Are the Responses to Major Comments? Comment: We received three comments on this topic. One supported revising the particulate matter standards by expressing all particulate matter standards in SI units as proposed. Two other commenters opposed the proposed revisions because converting a standard from gr/dscf to mg/dscm and rounding to two significant figures can E:\FR\FM\08APR1.SGM 08APR1 18974 Federal Register / Vol. 73, No. 68 / Tuesday, April 8, 2008 / Rules and Regulations increase (and apparently does for at least one affected source) the stringency of the standard. Response: Given that the proposed conversion to SI units can increase the stringency of the promulgated standard in some instances, we are not revising the particulate matter standards as proposed. We do not believe the proposed revisions are appropriate because a source currently complying with the standard expressed in English units could find itself suddenly out of compliance if the standard were converted to SI units, after rounding the result to two significant figures. We believe this would be an inappropriate outcome for this ‘‘housekeeping’’ amendment. 3. Corrections to the Notice of Intent To Comply (NIC) Provisions for New Units rwilkins on PROD1PC63 with RULES a. Summary of the Final Action. We proposed several corrections to the NIC regulatory provisions for new units to accurately reflect the time frames for holding the informal public meeting and submitting a final NIC. See 71 FR at 52645–646. Specifically, we made corrections to the time line (Figure 2; 71 FR at 52644), and proposed to revise § 63.1210(b)(3) and (c)(1), which are the core requirements for the informal public meeting and final NIC. We explained that it was our intent to clarify that existing units’ NIC deadlines were based upon the effective date of the rule (e.g., ‘‘* * * no later than one year following the effective date * * *’’), whereas new units’’ NIC deadlines were based upon a set number of days between NIC compliance activities (e.g., ‘‘* * * or 60 days following the informal public meeting’’). This was necessary because the final rule effective date has no bearing on new units. We further explained that since the public meetings for the NIC and the RCRA pre-application are to occur simultaneously for new units, we anticipate new units will plan accordingly and work with their permitting authorities to determine the most suitable time to begin the NIC compliance process. Today we are amending § 63.1210(b)(3) and (c)(1) to accurately reflect the time frames for holding the informal public meeting and submitting a final NIC for new units. However, the amendments are not finalized as proposed, but rather were revised to VerDate Aug<31>2005 16:20 Apr 07, 2008 Jkt 214001 reflect a comment we received (see below). We are now further subdividing the paragraphs to explicitly differentiate between ‘‘existing units’’ and ‘‘new units.’’ Also, to further clarify that new units are subject to the same NIC requirements, we have added a new paragraph (b)(5) to § 63.1212 with respect to the final NIC. While it essentially mirrors § 63.1210(b)(3), we believe it is important to clearly indicate all applicable NIC provisions for new units in § 63.1212. b. What Are the Responses to Major Comments? Comment: One comment was received in response to the proposed amendments. The commenter noted that the proposed § 63.1210(c)(1) language retains the 10 month deadline, but also requires that the meeting must be held no later than 30 days following the notice. The 30 day advance notice language of § 63.1210(c)(3) was retained. This puts the facility in a position of having to issue the public notice precisely 30 days before the public meeting (i.e., facilities have two 30 day deadlines, one working backward from the meeting date and one working forward from the notice date). The commenter suggested that the requirements for new units and existing units be presented as two separate paragraphs to better represent the timelines for each. Response: We agree with the commenter. The few words added to § 63.1210(c)(1) do not clearly differentiate between existing and new units’ NIC deadlines. The reference in § 63.1210(c)(1) to the ‘‘* * * no later than 10 months after the effective date * * *’’ was intended only for existing units and the proposed reference to ‘‘* * * or 30 days following notice * * *’’ was intended only for new units. The way the paragraph reads gives the appearance that both references may be applicable to all units. Therefore, if one reads the 30 day reference in § 63.1210(c)(1) to also apply to existing units, along with the 30 day reference which was retained in § 63.1210(c)(3), it creates the situation which the commenter correctly identifies. We have subdivided § 63.1210(c)(1) (as well as § 63.1210(b)(3)) to clearly designate applicability for existing and new units as the commenter suggests. Section 63.1210(c)(1) is revised to PO 00000 Frm 00032 Fmt 4700 Sfmt 4700 require the informal public meeting for new units to be held no earlier than 30 days following notice of the informal meeting, as opposed to no later than 30 days following the notice. Also, we have revised § 63.1212(b)(4) to state that the informal public meeting must be held no earlier than 30 days following notice of the meeting, so that it is consistent with § 63.1210(c)(1). Finally, as noted above, a new paragraph (b)(5) is added to § 63.1212 regarding submission of the final NIC. C. Corrections to the Startup, Shutdown, and Malfunction Plan Provisions This action also corrects a ministerial error by EPA that lead to inadvertent revision of § 63.1206(c)(2)(v). In a 2006 final rule amending the Part 63 general provisions, EPA made conforming changes to many individual MACT standards that merely incorporate the startup, shutdown and malfunction (SSM) requirements of the general provisions. 71 FR 20446 (April 20, 2006). In doing so, EPA inadvertently revised the SSM provisions tailored specifically for HWC facilities. Today, we are correcting that inadvertent error. Accordingly, we are revising § 63.1206(c)(2)(v)(A)(2) and (c)(2)(v)(B)(4) so that they read as they did before the April 20, 2006 revisions. D. Time Lines In the September 2006 proposed rule, we noted several errors in the time lines published in the October 12, 2005 final rule. See 70 FR 59524–525 and 71 FR at 52642–644. Consequently, we revised the time lines, Figures 1 and 2, to reflect the correct dates and time frames associated with compliance activities for Phase 1 (i.e., incinerators, cement kilns, and lightweight aggregate kilns) and Phase 2 sources (i.e., liquid and solid fuel boilers and hydrochloric acid production furnaces). In addition, we discussed the time line revisions and why the changes were necessary, as well as providing some clarifying remarks. We did not receive any public comments on the revised time lines that were published in the proposed rule. For the reader’s convenience, we are publishing the time lines again in today’s final rule. Please refer to the proposal for the accompanying discussion of the time lines. 71 FR at 52642–643.

Impacts of the Final Rule A. What facilities are affected by the final amendments? A description of the affected source categories is discussed in the April 20, 2004 proposed rule. 69 FR at 21207–09. In the October 12, 2005 final rule, we estimated that there are a total of 267 sources subject to the rule requirements, including 116 boilers (104 liquid fuel boilers and 12 solid fuel boilers), 92 onsite incinerators, 25 cement kilns, 15 commercial incinerators, 9 lightweight aggregate kilns, and 10 hydrochloric acid production furnaces. 70 FR at 59530. While we are aware of several changes to the universe of operating hazardous waste combustors, these estimates remain a reasonable representation of existing operating sources.4 B. What are the impacts of the final rule? The rule amendments do not change any of the impacts presented in the preamble to the October 12, 2005 final rule. See 70 FR at 59529–35. IV. Statutory and Executive Order Reviews A. Executive Order 12866: Regulatory Planning and Review This action is not a ‘‘significant regulatory action’’ under the terms of Executive Order 12866 (58 FR 51735, October 4, 1993) and is therefore not subject to OMB review. rwilkins on PROD1PC63 with RULES B. Paperwork Reduction Act This action does not impose any new information collection burden because there is no additional burden on affected sources as a result of the final rule. However, the Office of Management and Budget (OMB) has previously approved the information collection requirements contained in the existing regulations (see 40 CFR part 9) under the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. and has assigned OMB control number 2050–0171, EPA ICR number 1773.08. A copy of the OMB approved Information Collection Request (ICR) may be obtained by writing to: Director, Collection Strategies Division; U.S. Environmental Protection Agency (2822T); 1200 Pennsylvania Ave., NW., Washington, DC 20460 or by calling (202) 566–1700. Burden means the total time, effort, or financial resources expended by persons 4 Given the small size of the lightweight aggregate kiln category, it is worth mentioning that the Solite Cascade plant in Virginia has ceased operations. Prior to closure, this plant operated four kiln sources. See also 70 FR at 59426. VerDate Aug<31>2005 16:45 Apr 07, 2008 Jkt 214001 to generate, maintain, retain, or 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 are listed in 40 CFR part 9. 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 will not have a significant economic impact on a substantial number of small entities. Small entities include small businesses, small organizations, and small governmental jurisdictions. For purposes of assessing the impacts of today’s rule on small entities, small entity is defined as: (1) A small business as defined by the Small Business Administration’s (SBA) regulations at 13 CFR 121.201; (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 today’s final rule on small entities, I certify that this action will not have a significant economic impact on a substantial number of small entities. As discussed in the October 12, 2005 final rule (which today’s final rule amends), we determined that hazardous waste combustion facilities are not owned by small governmental jurisdictions or nonprofit organizations. 70 FR at 59538. Therefore, in that rule only small businesses were analyzed for small entity impacts (a small entity was defined either by the number of PO 00000 Frm 00035 Fmt 4700 Sfmt 4700 18977 employees or by the dollar amount of sales). We found that few—a total of eight out of 145 facilities—of the sources affected by the October 2005 rule were owned by small businesses. Finally, our analysis indicated that none of these facilities are likely to incur annualized compliance costs greater than one percent of gross annual corporate revenues. Cost impacts were found to range from less than 0.01 percent to 0.46 percent of annual gross corporate revenues. 70 FR at 59538. 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. We note that today’s final rule does not alter the number or type of small businesses that were discussed in the October 12, 2005 final rule. Additionally today’s rule does not have any significant new regulatory requirements as compared to the requirements discussed in the October 12, 2005 final rule. 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 to State, local, and tribal governments, in the aggregate, or to the private sector, of $100 million or more in any one 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 costeffective 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 E:\FR\FM\08APR1.SGM 08APR1 18978 Federal Register / Vol. 73, No. 68 / Tuesday, April 8, 2008 / Rules and Regulations rwilkins on PROD1PC63 with RULES 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 this rule does 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. This is because today’s final rule does not add new requirements that would increase the costs of the original NESHAP for hazardous waste combustors. The NESHAP was published on September 30, 1999, and October 12, 2005, and had aggregated annualized social costs between $50 to $63 million (64 FR at 53022) and $22.6 million (70 FR at 59538), respectively. Thus, today’s final rule is not subject to the requirements of sections 202 and 205 of the UMRA. In addition, EPA has determined that this final rule does not significantly or uniquely affect small governments because it contains no requirements that apply to such governments or impose obligations upon them. Therefore, this final rule is not subject to section 203 of the UMRA. E. Executive Order 13132: Federalism Executive Order 13132, entitled ‘‘Federalism’’ (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’’ is 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.’’ This final rule does not have federalism implications. The final rule does 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, because State and local governments do not own or operate any sources that would be subject to the requirements of the final rule and as such would not bear substantial costs of effects. Thus, Executive Order 13132 does not apply to this rule. VerDate Aug<31>2005 16:20 Apr 07, 2008 Jkt 214001 F. Executive Order 13175: Consultation and Coordination With Indian Tribal Governments Executive Order 13175, entitled ‘‘Consultation and Coordination with Indian Tribal Governments’’ (65 FR 67249, November 9, 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.’’ This final rule does not have tribal implications, as specified in Executive Order 13175, because tribal governments do not own or operate any sources subject to today’s action. Thus, Executive Order 13175 does not apply to this rule. G. Executive Order 13045: Protection of Children From Environmental Health Risks 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 EO 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, the Agency 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 the Agency. EPA interprets Executive Order 13045 as applying to those regulatory actions that concern health or safety risks, such that the analysis required under section 5–501 of the Order has the potential to influence the regulation. This final rule is not subject to Executive Order 13045 because it is based solely on technology performance and not on health or safety risks. Furthermore, this final rule is not considered ‘‘economically significant’’ as defined under EO 12866. H. Executive Order 13211: Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use This rule is not a ‘‘significant energy action’’ as defined in Executive Order 13211, ‘‘Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use’’ (66 FR 28355 (May 22, 2001)) because it is not likely to have a significant adverse effect on the supply, distribution, or use of energy. Further, we have concluded that this rule is not likely to have any adverse energy effects. PO 00000 Frm 00036 Fmt 4700 Sfmt 4700 I. National Technology Transfer and Advancement Act As noted in the proposed rule, Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (‘‘NTTAA’’), Public Law No. 104–113, 12(d) (15 U.S.C. 272 note) directs EPA to use voluntary consensus standards in its regulatory activities unless to do so would be inconsistent with applicable law or otherwise impractical. Voluntary consensus standards are technical standards (e.g., materials specifications, test methods, sampling procedures, and business practices) that are developed or adopted by voluntary consensus standards bodies. The NTTAA directs EPA to provide Congress, through OMB, explanations when the Agency decides not to use available and applicable voluntary consensus standards. This action involves technical standards. During the development of the final rule, EPA searched for voluntary consensus standards that might be applicable. EPA adopted the following standards as practical alternatives to specified EPA test methods in the final rule: (1) American Society for Testing and Materials (ASTM) D6735–01, ‘‘Standard Test Method for Measurement of Gaseous Chlorides and Fluorides from Mineral Calcining Exhaust Sources—Impinger Method,’’ and (2) American Society of Mechanical Engineers (ASME) standard QHO–1–2004, ‘‘Standard for the Qualification and Certification of Hazardous Waste Incinerator Operators.’’ Section 63.1208 lists the test methods to determine compliance with the emission standards in the final rule. Under § 63.7(f) of the general provisions, a source may apply to EPA for permission to use alternative test methods in place of any required testing method, performance specification, or procedure. J. Executive Order 12898: Federal Actions To Address Environmental Justice in Minority Populations and Low-Income Populations Executive Order 12898 (59 FR 7629 (Feb. 16, 1994)) establishes federal executive policy on environmental justice. Its main provision directs federal agencies, to the greatest extent practicable and permitted by law, to make environmental justice part of their mission by identifying and addressing, as appropriate, disproportionately high and adverse human health or environmental effects of their programs, policies, and activities on minority E:\FR\FM\08APR1.SGM 08APR1 Federal Register / Vol. 73, No. 68 / Tuesday, April 8, 2008 / Rules and Regulations populations and low-income populations in the United States. EPA has determined that this final rule will not have disproportionately high and adverse human health or environmental effects on minority or low-income populations because the provisions contained within do not affect the level of protection to human health of the environment. The final amendments to the hazardous waste combustor NESHAP (40 CFR part 63 subpart EEE) are comprised of clarifications and revisions to current compliance and monitoring provisions that do not affect the current level of control at facilities subject to these rules. K. Congressional Review 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. EPA will submit a report containing this action 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. 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). This final rule will be effective on April 8, 2008. PART 63—NATIONAL EMISSIONS STANDARDS FOR HAZARDOUS AIR POLLUTANTS FOR SOURCE CATEGORIES 1.

ACTION: Final rule. rwilkins on PROD1PC63 with RULES AGENCY: SUMMARY: NMFS issues this final rule to clarify the existing sea turtle conservation requirements for sea scallop dredge vessels entering waters south of 41°9.0′ N. latitude from May 1 through November 30 each year and to add a transiting provision to the requirements. Any vessel with a sea scallop dredge and required to have a Federal Atlantic sea scallop fishery VerDate Aug<31>2005 16:20 Apr 07, 2008 Jkt 214001 permit, regardless of dredge size or vessel permit category, that enters waters south of 41°9.0′ N. latitude, from the shoreline to the outer boundary of the Exclusive Economic Zone (EEZ) must have a chain mat on each dredge, unless the terms of the transiting provision are met. The chain-mat modified dredge is necessary to help reduce mortality and injury to endangered and threatened sea turtles in scallop dredge gear and to conserve sea turtles listed under the Endangered Species Act (ESA). This current action addresses a procedural error in the original rulemaking to require chain mats on scallop dredge gear, clarifies the existing requirements, and adds a transiting provision to the regulations. Any incidental take of threatened sea turtles in sea scallop dredge gear in compliance with this gear modification requirement and all other applicable requirements will be exempted from the ESA’s take prohibition. DATES: Effective May 8, 2008. ADDRESSES: Copies of the Environmental Assessment (EA) and Regulatory Impact Review/Final Regulatory Flexibility Analysis (RIR/ FRFA) prepared for this final rule may be obtained by writing to Ellen Keane, NMFS, Northeast Region, One Blackburn Drive, Gloucester, MA 01930.

SUPPLEMENTARY INFORMATION: Background All sea turtles that occur in U.S. waters are listed as either endangered or threatened under the Endangered Species Act of 1973 (ESA). The Kemp’s ridley (Lepidochelys kempii), leatherback (Dermochelys coriacea), and hawksbill (Eretmochelys imbricata) sea turtles are listed as endangered. The loggerhead (Caretta caretta) and green (Chelonia mydas) sea turtles are listed as threatened, except for breeding populations of green turtles in Florida and on the Pacific coast of Mexico that are listed as endangered. Due to the inability to distinguish between these populations of green turtles away from the nesting beach, NMFS considers green sea turtles endangered wherever they occur in U.S. waters. Kemp’s ridley, hawksbill, loggerhead, and green sea turtles are hard-shelled sea turtles. The incidental take, both lethal and non-lethal, of loggerhead, Kemp’s ridley, and unidentified hard-shelled PO 00000 Frm 00042 Fmt 4700 Sfmt 4700 sea turtles has been documented in the sea scallop dredge fishery, as well as a non-lethal take of a green sea turtle (NEFSC FSB, Observer Database). In addition, an unconfirmed take of a leatherback sea turtle was reported during the experimental fishery to test the chain-mat modified dredge gear (DuPaul et al., 2004). This action is being taken under the ESA provisions authorizing the issuance of regulations to conserve threatened species and for enforcement purposes (sections 4(d) and 11(f), respectively). The requirement to use chain-mat modified dredge gear is necessary to provide for the conservation of threatened loggerhead sea turtles, and will have ancillary benefits for other sea turtle species that have been taken in the sea scallop dredge fishery, albeit to a lesser extent than loggerheads. Under the ESA and its implementing regulations, taking endangered sea turtles—even incidentally—is prohibited. The incidental take of endangered species may only legally be exempted by an incidental take statement (ITS) or an incidental take permit issued pursuant to section 7 or 10 the ESA, respectively. Existing sea turtle conservation regulations at 50 CFR 223.206(d) exempt fishing activities and scientific research from the prohibition on takes of threatened species under certain conditions. Any incidental take of threatened loggerhead sea turtles in sea scallop dredge gear in compliance with this gear modification requirement and other applicable requirements is exempted from the prohibition against takes. The chain-mat modified dredge is expected to benefit sea turtles following an interaction in the water column. Based on the available information, NMFS has determined that the use of a chain-mat modified dredge will prevent most captures of sea turtles in the dredge bag as well as any ensuing injuries as a result of such capture (e.g., crushing in the dredge bag, crushing on deck, etc.). However, NMFS has made the conservative assumption that a turtle in a bottom interaction sustains significant injuries on the bottom, so, under this conservative assumption, there would not be a benefit from the chain mat for bottom interactions. This assumption, however, may be too conservative in that it is possible (although not likely) that turtles in a bottom interaction only receive minor injuries. In the unlikely scenario of a turtle receiving only minor injuries following a bottom interaction, the chain mat modification would prevent significant injuries that result from capture in the dredge bag (i.e, injuries E:\FR\FM\08APR1.SGM 08APR1

EPA promulgated on October 12, 2005. The amendments to the October 2005 
final rule clarify several compliance and monitoring provisions, and 
also correct several omissions and typographical errors in the final 
rule. We are finalizing the amendments to facilitate compliance and 
improve understanding of the final rule requirements. This rule does 
not address issues for which petitioners sought reconsideration. Nor 
does it address issues raised in EPA's comment solicitation of 
September 27, 2007.

DATES: The final rule is effective on April 8, 2008.

I. Background

A. What Is the Source of Authority for the Development of NESHAP?

    Section 112(c) of the Clean Air Act requires EPA to list categories 
and subcategories of major sources and area sources of hazardous air 
pollutants (HAP) and to establish NESHAP for the listed source 
categories and subcategories. Hazardous waste combustors include 
incinerators, cement kilns, lightweight aggregate kilns, boilers, and 
hydrochloric acid production furnaces that burn hazardous waste. EPA's 
initial list of categories of major and area sources of HAP was 
published on July 16, 1992 (57 FR 31576). Hazardous waste incinerators, 
Portland cement manufacturing, clay products manufacturing (including 
lightweight aggregate kilns), industrial/commercial/institutional 
boilers and process heaters, and hydrochloric acid production furnaces 
were among the listed categories of sources. Major sources of HAP are 
those sources that have the potential to emit at least 10 tons per year 
of any one HAP or 25 tons per year of any combination of HAP.

B. How Did the Public Participate in Developing the Amendments to the 
Final Rule?

    The final rule was published on October 12, 2005 (70 FR 59402) and 
codified in 40 CFR part 63, subpart EEE. Following publication of the 
final rule, two industry trade associations identified a number of 
typographical errors and suggested several potential compliance and 
monitoring amendments and clarifications to the rule.\1\ On September 
6, 2006, we published proposed amendments (71 FR at 52639) to address 
these issues and sought public comment on the proposed amendments.\2\ 
EPA received comments from five entities. Today's action presents EPA's 
responses to those comments and promulgates amendments to Subpart EEE 
of 40 CFR part 63.
---------------------------------------------------------------------------

    \1\ See docket items EPA-HQ-OAR-2004-0022-0551 and 0552.
    \2\ In addition to soliciting comment on the rule amendments 
discussed in this action, EPA also requested comment on other issues 
in the September 6, 2006 proposed rule. The other issues related to 
our response to four petitions for reconsideration that were 
submitted to the Administrator pursuant to section 307(d)(7)(B) of 
the Clean Air Act. EPA's final response to the petitions for 
reconsideration is not included in today's action. See Sections II, 
III, and IV of the September 2006 notice for additional information 
on the reconsideration proceedings. Nor does this final rule address 
any of the issues raised by EPA's solicitation of comment published 
on September 27, 2007 (72 FR 54875).
---------------------------------------------------------------------------

II. Summary of the Final Amendments

    In today's notice, we are announcing our final action on several 
amendments to Subpart EEE of 40 CFR part 63. The amendments revise 
several compliance and monitoring provisions in response to questions 
and issues raised by entities affected by the rule. The revised 
provisions are effective immediately, and today's final rule does not 
change the October 14, 2008 compliance date established by the October 
12, 2005 final rule. See also Section III (Time Lines for compliance 
activities) in today's action. Sources can readily comply with the 
revised provisions promulgated today within the compliance time frames 
established by the October 12, 2005 final rule. See Sec.  63.1206(a).

 A. Proposed Amendments for Which No Adverse Comments Were Received

    In the September 6, 2006 proposal, we proposed several corrections 
and clarifications to the NESHAP for hazardous waste combustors. 71 FR 
at 52639-642, 52645-646. We received no adverse comments on the 
majority of the corrections and clarifications (see Table 1 below). 
Therefore, we are promulgating those provisions, as proposed, without 
further discussion.\3\ The reader is referred to the September 2006 
proposed rule for background on these changes.
---------------------------------------------------------------------------

    \3\ Please note, however, that we have revised proposed Sec.  
63.1207(d)(2), which prescribes the schedule for confirmatory 
performance testing, to conform with existing Sec.  63.1207(b)(3) to 
clarify further that confirmatory performance testing is not 
required for sources that are not subject to a numerical D/F 
emission standard: solid fuel boilers and hydrochloric acid 
production furnaces; lightweight aggregate kilns that are not 
subject to a numerical dioxin/furan emission standard under Sec.  
63.1221; and liquid fuel boilers that are not subject to a numerical 
dioxin/furan emission standard under Sec.  63.1217.

------------------------------------------------------------------------

    We also received no adverse comment on the proposed amendments 
described in Section V.G (Calculating Rolling Averages for Averaging 
Periods in Excess of 12 Hours) of the September 6, 2006 preamble 
citation. That discussion described our intent to simplify the 
monitoring requirements for sources that select mercury or semivolatile 
metal feedrate limits averaged over periods greater than 12 hours. As 
described in the preamble, this would require identical changes to four 
paragraphs of the regulation: Sec. Sec.  63.1209(n)(2)(v)(A)(2)(iv), 
63.1209(n)(2)(v)(A)(3)(v), 63.1209(l)(1)(ii)(B)(5), and 
63.1209(l)(1)(ii)(C)(5). However, corresponding regulatory changes to 
the latter three paragraphs were inadvertently omitted from the 
September 2006 proposed rule. In today's rule, we are correcting this 
oversight by promulgating the language proposed for Sec.  
63.1209(n)(2)(v)(A)(2)(iv) in all four paragraphs.

B. Proposed Amendments for Which Comments Were Received

1. Calculating Rolling Averages
    a. Summary of the Final Action. We are revising Sec. Sec.  
63.1209(n)(2)(v)(B)(1), 63.1209(n)(2)(v)(B)(2), and 
63.1209(o)(1)(ii)(A)(3) as proposed on September 6, 2006. 71 FR at 
52640. These changes are intended to clarify that data for 
demonstrating compliance with feed rate limits of up to a 12-hour 
rolling average must be updated each minute. In addition, Sec.  
63.1209(n)(2)(v)(B)(1)(i) is modified to confirm that the chromium feed 
rate limit for boilers burning liquid hazardous waste with a heating 
value of 10,000 Btu/lb or greater is a 12-hour rolling average limit.
    b. What Are the Responses to Major Comments?
    Comment: We received two comments on this topic. One supported the 
changes as proposed. The other commenter objected to updating the 12-
hour average every minute rather than every hour, arguing that this 
complicates data management and could require increased data storage.
    Response: We believe that complications to data management or 
increases in data storage requirements, if any, are negligible. Phase I 
sources--incinerators, cement kilns, and lightweight aggregate kilns--
have been complying with 12-hour averages updated each minute for 
several years without significant problems. Furthermore, data storage 
is not measurably affected. These continuous monitors are required to 
record a data point at least once each minute, regardless of the 
whether the rolling average value for determining compliance is updated 
each minute or each hour. Consequently, the amount of recorded data is 
not significantly affected under either approach to calculating the 
rolling average.
    Phase I sources have been required to update their 12-hour rolling 
average feed rate data each minute ever since the hazardous waste 
combustor MACT rule was first promulgated in 1999. A ``rolling 
average'' was defined in that rule as ``the average of all one-minute 
averages over the averaging period.'' That definition has remained the 
same through the interim standards (for Phase I sources) and the 
replacement standards. We have consistently interpreted the definition 
to require that a new rolling average be calculated each minute. See, 
for example, the preamble discussion in the September 30, 1999 rule 
which says, while discussing how to calculate rolling averages upon 
initial startup, ``Given that the one-hour, and 12-hour rolling 
averages for limits on various parameters must be updated each minute * 
* *'' 64 FR at 52924.
    In the 2004 replacement standards proposed rule, we first 
introduced the concept of hourly updates to rolling averages, but only 
in the context of monitoring compliance with annual rolling average 
feed rate limits. See 69 FR at 21312. At no time did we discuss or 
propose any change to the long-standing requirement that rolling 
averages of 12 hours or less be updated each minute. In fact, we 
reiterated the requirement for one-minute updates in discussing how 
compliance with the 12-hour thermal feed rate limits would be 
monitored. In that discussion we said that ``For compliance, you would 
continuously monitor the feed rate of hazardous waste on a 12-hour 
rolling average updated each minute or, for standards based on normal 
emissions, on an annual rolling average updated each hour.'' Id. at 
21312.
    Given that we have consistently required rolling averages of 12 
hours or less to be updated each minute and we have never discussed or 
proposed any changes to that approach, we find ample evidence that the 
addition of hourly updates for these parameters in the final 
replacement standards were, as we asserted in the proposed rule, 
inadvertent. Furthermore, we find no support for the commenter's claim 
that data management or data storage requirements are significantly 
affected under either approach. Therefore, we have removed the 
references to hourly updates, as proposed.
2. Expressing Particulate Matter Standards Using the International 
System of Units
    a. Summary of the Final Action. We proposed to revise the 
particulate matter standards expressed in English units (gr/dscf) in 
Sec. Sec.  63.1216 through 63.1221 by converting and expressing the 
standards using the International System of Units (SI). 71 FR at 52641. 
However, after considering the comments received in response to the 
proposed rule, we are not revising the standards as proposed. Thus, we 
are retaining the format of the particulate matter standards as 
promulgated in the October 12, 2005 final rule.
    b. What Are the Responses to Major Comments?
    Comment: We received three comments on this topic. One supported 
revising the particulate matter standards by expressing all particulate 
matter standards in SI units as proposed. Two other commenters opposed 
the proposed revisions because converting a standard from gr/dscf to 
mg/dscm and rounding to two significant figures can

[[Page 18974]]

increase (and apparently does for at least one affected source) the 
stringency of the standard.
    Response: Given that the proposed conversion to SI units can 
increase the stringency of the promulgated standard in some instances, 
we are not revising the particulate matter standards as proposed. We do 
not believe the proposed revisions are appropriate because a source 
currently complying with the standard expressed in English units could 
find itself suddenly out of compliance if the standard were converted 
to SI units, after rounding the result to two significant figures. We 
believe this would be an inappropriate outcome for this 
``housekeeping'' amendment.
3. Corrections to the Notice of Intent To Comply (NIC) Provisions for 
New Units
    a. Summary of the Final Action. We proposed several corrections to 
the NIC regulatory provisions for new units to accurately reflect the 
time frames for holding the informal public meeting and submitting a 
final NIC. See 71 FR at 52645-646. Specifically, we made corrections to 
the time line (Figure 2; 71 FR at 52644), and proposed to revise Sec.  
63.1210(b)(3) and (c)(1), which are the core requirements for the 
informal public meeting and final NIC. We explained that it was our 
intent to clarify that existing units' NIC deadlines were based upon 
the effective date of the rule (e.g., ``* * * no later than one year 
following the effective date * * *''), whereas new units'' NIC 
deadlines were based upon a set number of days between NIC compliance 
activities (e.g., ``* * * or 60 days following the informal public 
meeting''). This was necessary because the final rule effective date 
has no bearing on new units. We further explained that since the public 
meetings for the NIC and the RCRA pre-application are to occur 
simultaneously for new units, we anticipate new units will plan 
accordingly and work with their permitting authorities to determine the 
most suitable time to begin the NIC compliance process.
    Today we are amending Sec.  63.1210(b)(3) and (c)(1) to accurately 
reflect the time frames for holding the informal public meeting and 
submitting a final NIC for new units. However, the amendments are not 
finalized as proposed, but rather were revised to reflect a comment we 
received (see below). We are now further subdividing the paragraphs to 
explicitly differentiate between ``existing units'' and ``new units.'' 
Also, to further clarify that new units are subject to the same NIC 
requirements, we have added a new paragraph (b)(5) to Sec.  63.1212 
with respect to the final NIC. While it essentially mirrors Sec.  
63.1210(b)(3), we believe it is important to clearly indicate all 
applicable NIC provisions for new units in Sec.  63.1212.
    b. What Are the Responses to Major Comments?
    Comment: One comment was received in response to the proposed 
amendments. The commenter noted that the proposed Sec.  63.1210(c)(1) 
language retains the 10 month deadline, but also requires that the 
meeting must be held no later than 30 days following the notice. The 30 
day advance notice language of Sec.  63.1210(c)(3) was retained. This 
puts the facility in a position of having to issue the public notice 
precisely 30 days before the public meeting (i.e., facilities have two 
30 day deadlines, one working backward from the meeting date and one 
working forward from the notice date). The commenter suggested that the 
requirements for new units and existing units be presented as two 
separate paragraphs to better represent the timelines for each.
    Response: We agree with the commenter. The few words added to Sec.  
63.1210(c)(1) do not clearly differentiate between existing and new 
units' NIC deadlines. The reference in Sec.  63.1210(c)(1) to the ``* * 
* no later than 10 months after the effective date * * *'' was intended 
only for existing units and the proposed reference to ``* * * or 30 
days following notice * * *'' was intended only for new units. The way 
the paragraph reads gives the appearance that both references may be 
applicable to all units. Therefore, if one reads the 30 day reference 
in Sec.  63.1210(c)(1) to also apply to existing units, along with the 
30 day reference which was retained in Sec.  63.1210(c)(3), it creates 
the situation which the commenter correctly identifies.
    We have subdivided Sec.  63.1210(c)(1) (as well as Sec.  
63.1210(b)(3)) to clearly designate applicability for existing and new 
units as the commenter suggests. Section 63.1210(c)(1) is revised to 
require the informal public meeting for new units to be held no earlier 
than 30 days following notice of the informal meeting, as opposed to no 
later than 30 days following the notice. Also, we have revised Sec.  
63.1212(b)(4) to state that the informal public meeting must be held no 
earlier than 30 days following notice of the meeting, so that it is 
consistent with Sec.  63.1210(c)(1). Finally, as noted above, a new 
paragraph (b)(5) is added to Sec.  63.1212 regarding submission of the 
final NIC.

C. Corrections to the Startup, Shutdown, and Malfunction Plan 
Provisions

    This action also corrects a ministerial error by EPA that lead to 
inadvertent revision of Sec.  63.1206(c)(2)(v). In a 2006 final rule 
amending the Part 63 general provisions, EPA made conforming changes to 
many individual MACT standards that merely incorporate the startup, 
shutdown and malfunction (SSM) requirements of the general provisions. 
71 FR 20446 (April 20, 2006). In doing so, EPA inadvertently revised 
the SSM provisions tailored specifically for HWC facilities. Today, we 
are correcting that inadvertent error. Accordingly, we are revising 
Sec.  63.1206(c)(2)(v)(A)(2) and (c)(2)(v)(B)(4) so that they read as 
they did before the April 20, 2006 revisions.

D. Time Lines

    In the September 2006 proposed rule, we noted several errors in the 
time lines published in the October 12, 2005 final rule. See 70 FR 
59524-525 and 71 FR at 52642-644. Consequently, we revised the time 
lines, Figures 1 and 2, to reflect the correct dates and time frames 
associated with compliance activities for Phase 1 (i.e., incinerators, 
cement kilns, and lightweight aggregate kilns) and Phase 2 sources 
(i.e., liquid and solid fuel boilers and hydrochloric acid production 
furnaces). In addition, we discussed the time line revisions and why 
the changes were necessary, as well as providing some clarifying 
remarks.
    We did not receive any public comments on the revised time lines 
that were published in the proposed rule. For the reader's convenience, 
we are publishing the time lines again in today's final rule. Please 
refer to the proposal for the accompanying discussion of the time 
lines. 71 FR at 52642-643.

III. Impacts of the Final Rule

A. What facilities are affected by the final amendments?

    A description of the affected source categories is discussed in the 
April 20, 2004 proposed rule. 69 FR at 21207-09. In the October 12, 
2005 final rule, we estimated that there are a total of 267 sources 
subject to the rule requirements, including 116 boilers (104 liquid 
fuel boilers and 12 solid fuel boilers), 92 on-site incinerators, 25 
cement kilns, 15 commercial incinerators, 9 lightweight aggregate 
kilns, and 10 hydrochloric acid production furnaces. 70 FR at 59530. 
While we are aware of several changes to the universe of operating 
hazardous waste combustors, these estimates remain a reasonable 
representation of existing operating sources.\4\
---------------------------------------------------------------------------

    \4\ Given the small size of the lightweight aggregate kiln 
category, it is worth mentioning that the Solite Cascade plant in 
Virginia has ceased operations. Prior to closure, this plant 
operated four kiln sources. See also 70 FR at 59426.
---------------------------------------------------------------------------

B. What are the impacts of the final rule?

    The rule amendments do not change any of the impacts presented in 
the preamble to the October 12, 2005 final rule. See 70 FR at 59529-35.

IV. Statutory and Executive Order Reviews

A. Executive Order 12866: Regulatory Planning and Review

    This action is not a ``significant regulatory action'' under the 
terms of Executive Order 12866 (58 FR 51735, October 4, 1993) and is 
therefore not subject to OMB review.

B. Paperwork Reduction Act

    This action does not impose any new information collection burden 
because there is no additional burden on affected sources as a result 
of the final rule. However, the Office of Management and Budget (OMB) 
has previously approved the information collection requirements 
contained in the existing regulations (see 40 CFR part 9) under the 
provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. and 
has assigned OMB control number 2050-0171, EPA ICR number 1773.08. A 
copy of the OMB approved Information Collection Request (ICR) may be 
obtained by writing to: Director, Collection Strategies Division; U.S. 
Environmental Protection Agency (2822T); 1200 Pennsylvania Ave., NW., 
Washington, DC 20460 or by calling (202) 566-1700.
    Burden means the total time, effort, or financial resources 
expended by persons to generate, maintain, retain, or 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 are listed in 40 CFR part 9.

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 will not have a significant economic impact on a substantial 
number of small entities. Small entities include small businesses, 
small organizations, and small governmental jurisdictions.
    For purposes of assessing the impacts of today's rule on small 
entities, small entity is defined as: (1) A small business as defined 
by the Small Business Administration's (SBA) regulations at 13 CFR 
121.201; (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 today's final rule on 
small entities, I certify that this action will not have a significant 
economic impact on a substantial number of small entities. As discussed 
in the October 12, 2005 final rule (which today's final rule amends), 
we determined that hazardous waste combustion facilities are not owned 
by small governmental jurisdictions or nonprofit organizations. 70 FR 
at 59538. Therefore, in that rule only small businesses were analyzed 
for small entity impacts (a small entity was defined either by the 
number of employees or by the dollar amount of sales). We found that 
few--a total of eight out of 145 facilities--of the sources affected by 
the October 2005 rule were owned by small businesses. Finally, our 
analysis indicated that none of these facilities are likely to incur 
annualized compliance costs greater than one percent of gross annual 
corporate revenues. Cost impacts were found to range from less than 
0.01 percent to 0.46 percent of annual gross corporate revenues. 70 FR 
at 59538.
    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. We note that 
today's final rule does not alter the number or type of small 
businesses that were discussed in the October 12, 2005 final rule. 
Additionally today's rule does not have any significant new regulatory 
requirements as compared to the requirements discussed in the October 
12, 2005 final rule.

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 to State, local, and tribal governments, in 
the aggregate, or to the private sector, of $100 million or more in any 
one 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

[[Page 18978]]

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 this rule does 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. This is because today's final rule does not add 
new requirements that would increase the costs of the original NESHAP 
for hazardous waste combustors. The NESHAP was published on September 
30, 1999, and October 12, 2005, and had aggregated annualized social 
costs between $50 to $63 million (64 FR at 53022) and $22.6 million (70 
FR at 59538), respectively. Thus, today's final rule is not subject to 
the requirements of sections 202 and 205 of the UMRA. In addition, EPA 
has determined that this final rule does not significantly or uniquely 
affect small governments because it contains no requirements that apply 
to such governments or impose obligations upon them. Therefore, this 
final rule is not subject to section 203 of the UMRA.

E. Executive Order 13132: Federalism

    Executive Order 13132, entitled ``Federalism'' (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'' is 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.''
    This final rule does not have federalism implications. The final 
rule does 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, because State and 
local governments do not own or operate any sources that would be 
subject to the requirements of the final rule and as such would not 
bear substantial costs of effects. Thus, Executive Order 13132 does not 
apply to this rule.

F. Executive Order 13175: Consultation and Coordination With Indian 
Tribal Governments

    Executive Order 13175, entitled ``Consultation and Coordination 
with Indian Tribal Governments'' (65 FR 67249, November 9, 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.'' This final rule does not have 
tribal implications, as specified in Executive Order 13175, because 
tribal governments do not own or operate any sources subject to today's 
action. Thus, Executive Order 13175 does not apply to this rule.

G. Executive Order 13045: Protection of Children From Environmental 
Health Risks 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 EO 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, the 
Agency 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 the Agency.
    EPA interprets Executive Order 13045 as applying to those 
regulatory actions that concern health or safety risks, such that the 
analysis required under section 5-501 of the Order has the potential to 
influence the regulation. This final rule is not subject to Executive 
Order 13045 because it is based solely on technology performance and 
not on health or safety risks. Furthermore, this final rule is not 
considered ``economically significant'' as defined under EO 12866.

H. Executive Order 13211: Actions Concerning Regulations That 
Significantly Affect Energy Supply, Distribution, or Use

    This rule is not a ``significant energy action'' as defined in 
Executive Order 13211, ``Actions Concerning Regulations That 
Significantly Affect Energy Supply, Distribution, or Use'' (66 FR 28355 
(May 22, 2001)) because it is not likely to have a significant adverse 
effect on the supply, distribution, or use of energy. Further, we have 
concluded that this rule is not likely to have any adverse energy 
effects.

I. National Technology Transfer and Advancement Act

    As noted in the proposed rule, Section 12(d) of the National 
Technology Transfer and Advancement Act of 1995 (``NTTAA''), Public Law 
No. 104-113, 12(d) (15 U.S.C. 272 note) directs EPA to use voluntary 
consensus standards in its regulatory activities unless to do so would 
be inconsistent with applicable law or otherwise impractical. Voluntary 
consensus standards are technical standards (e.g., materials 
specifications, test methods, sampling procedures, and business 
practices) that are developed or adopted by voluntary consensus 
standards bodies. The NTTAA directs EPA to provide Congress, through 
OMB, explanations when the Agency decides not to use available and 
applicable voluntary consensus standards.
    This action involves technical standards. During the development of 
the final rule, EPA searched for voluntary consensus standards that 
might be applicable. EPA adopted the following standards as practical 
alternatives to specified EPA test methods in the final rule: (1) 
American Society for Testing and Materials (ASTM) D6735-01, ``Standard 
Test Method for Measurement of Gaseous Chlorides and Fluorides from 
Mineral Calcining Exhaust Sources--Impinger Method,'' and (2) American 
Society of Mechanical Engineers (ASME) standard QHO-1-2004, ``Standard 
for the Qualification and Certification of Hazardous Waste Incinerator 
Operators.''
    Section 63.1208 lists the test methods to determine compliance with 
the emission standards in the final rule. Under Sec.  63.7(f) of the 
general provisions, a source may apply to EPA for permission to use 
alternative test methods in place of any required testing method, 
performance specification, or procedure.

J. Executive Order 12898: Federal Actions To Address Environmental 
Justice in Minority Populations and Low-Income Populations

    Executive Order 12898 (59 FR 7629 (Feb. 16, 1994)) establishes 
federal executive policy on environmental justice. Its main provision 
directs federal agencies, to the greatest extent practicable and 
permitted by law, to make environmental justice part of their mission 
by identifying and addressing, as appropriate, disproportionately high 
and adverse human health or environmental effects of their programs, 
policies, and activities on minority

[[Page 18979]]

populations and low-income populations in the United States.
    EPA has determined that this final rule will not have 
disproportionately high and adverse human health or environmental 
effects on minority or low-income populations because the provisions 
contained within do not affect the level of protection to human health 
of the environment. The final amendments to the hazardous waste 
combustor NESHAP (40 CFR part 63 subpart EEE) are comprised of 
clarifications and revisions to current compliance and monitoring 
provisions that do not affect the current level of control at 
facilities subject to these rules.

K. Congressional Review

    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. EPA will submit a report containing this action 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. 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). This final rule will be effective on April 8, 2008.

Sec.  63.1207  What are the performance testing requirements?

* * * * *
    (b) * * *
    (3) * * *
    (vi) Sources that are required to perform the one-time dioxin/furan 
test pursuant to paragraph (b)(3) of this section are not required to 
perform confirmatory performance tests.
* * * * *
    (d) * * *
    (1) Comprehensive performance testing. Except as otherwise 
specified in paragraph (d)(4) of this section, you must commence 
testing no later than 61 months after the date of commencing the 
previous comprehensive performance test used to show compliance with 
Sec. Sec.  63.1216, 63.1217, 63.1218, 63.1219, 63.1220, or 63.1221. If 
you submit data in lieu of the initial performance test, you must 
commence the subsequent comprehensive performance test within 61 months 
of commencing the test used to provide the data in lieu of the initial 
performance test.
    (2) Confirmatory performance testing. Except as otherwise specified 
in paragraph (d)(4) of this section, you must commence confirmatory 
performance testing no later than 31 months after the date of 
commencing the previous comprehensive performance test used to show 
compliance with Sec. Sec.  63.1217, 63.1219, 63.1220, or 63.1221. If 
you submit data in lieu of the initial performance test, you must 
commence the initial confirmatory performance test within 31 months of 
the date six months after the compliance date. To ensure that the 
confirmatory test is conducted approximately midway between 
comprehensive performance tests, the Administrator will not approve a 
test plan that schedules testing within 18 months of commencing the 
previous comprehensive performance test.
* * * * *
    (4) Applicable testing requirements under the interim standards. 
(i) Waiver of periodic comprehensive performance tests. Except as 
provided by paragraph (c)(2) of this section, you must conduct only an 
initial comprehensive performance test under the interim standards 
(Sec. Sec.  63.1203 through 63.1205); all subsequent comprehensive 
performance testing requirements are waived under the interim 
standards. The provisions in the introductory text to paragraph (d) and 
in paragraph (d)(1) of this section apply only to tests used to 
demonstrate compliance with the replacement standards promulgated on or 
after October 12, 2005.
    (ii) Waiver of confirmatory performance tests. You are not required 
to conduct a confirmatory test under the interim standards (Sec. Sec.  
63.1203 through 63.1205). The confirmatory testing requirements in the 
introductory text to paragraph (d) and in paragraph (d)(2) of this 
section apply only after you have demonstrated compliance with the 
replacement standards promulgated on or after October 12, 2005.

    (2) * * *
    (i) Carbon monoxide (or hydrocarbon) CEMS emissions levels must be 
within the range of the average value to the maximum value allowed, 
except as provided by paragraph (g)(2)(v) of this section. * * *
    (ii) Each operating limit (specified in Sec.  63.1209) established 
to maintain compliance with the dioxin/furan emission standard must be 
held within the range of the average value over the previous 12 months 
and the maximum or minimum, as appropriate, that is allowed, except as 
provided by paragraph (g)(2)(v) of this section. * * *
* * * * *
    (m) Waiver of performance test. You are not required to conduct 
performance tests to document compliance with the mercury, semivolatile 
metals, low volatile metals, or hydrogen chloride/chlorine gas emission 
standards under the conditions specified in paragraphs (m)(1) or (m)(2) 
of this section. The waiver provisions of this paragraph apply in 
addition to the provisions of Sec.  63.7(h).
    (1) Emission standards based on exhaust gas flow rate. (i) You are 
deemed to be in compliance with an emission standard based on the 
volumetric flow rate of exhaust gas (i.e. [mu]g/dscm or ppmv) if the 
twelve-hour rolling average maximum theoretical emission concentration 
(MTEC) determined as specified below does not exceed the emission 
standard:
    (A) Determine the feedrate of mercury, semivolatile metals, low 
volatile metals, or total chlorine and chloride from all feedstreams;
    (B) Determine the stack gas flowrate; and
    (C) Calculate a MTEC for each standard assuming all mercury, 
semivolatile metals, low volatile metals, or total chlorine (organic 
and inorganic) from all feedstreams is emitted;
    (ii) To document compliance with this provision, you must:
    (A) Monitor and record the feedrate of mercury, semivolatile 
metals, low volatile metals, and total chlorine and chloride from all 
feedstreams according to Sec.  63.1209(c);
    (B) Monitor with a CMS and record in the operating record the gas 
flowrate (either directly or by monitoring a surrogate parameter that 
you have correlated to gas flowrate);
    (C) Continuously calculate and record in the operating record the 
MTEC under the procedures of paragraph (m)(1)(i) of this section; and
    (D) Interlock the MTEC calculated in paragraph (m)(1)(i)(C) of this 
section to the AWFCO system to stop hazardous waste burning when the 
MTEC exceeds the emission standard.

[[Page 18981]]

    (iii) in lieu of the requirement in paragraphs (m)(1)(ii)(C) and 
(D) of this section, you may:
    (A) Identify in the Notification of Compliance a minimum gas 
flowrate limit and a maximum feedrate limit of mercury, semivolatile 
metals, low volatile metals, and/or total chlorine and chloride from 
all feedstreams that ensures the MTEC as calculated in paragraph 
(m)(1)(i)(C) of this section is below the applicable emission standard; 
and
    (B) Interlock the minimum gas flowrate limit and maximum feedrate 
limit of paragraph (m)(1)(iii)(A) of this section to the AWFCO system 
to stop hazardous waste burning when the gas flowrate or mercury, 
semivolatile metals, low volatile metals, and/or total chlorine and 
chloride feedrate exceeds the limits of paragraph (m)(1)(iii)(A) of 
this section.
    (2) Emission standards based on hazardous waste thermal 
concentration. (i) You are deemed to be in compliance with an emission 
standard specified on a hazardous waste thermal concentration basis 
(i.e., pounds emitted per million Btu of heat input) if the HAP thermal 
concentration in the waste feed does not exceed the allowable HAP 
thermal concentration emission rate.
    (ii) To document compliance with this provision, you must:
    (A) Monitor and record the feedrate of mercury, semivolatile 
metals, low volatile metals, and total chlorine and chloride from all 
hazardous waste feedstreams in accordance with Sec.  63.1209(c);
    (B) Determine and record the higher heating value of each hazardous 
waste feed;
    (C) Continuously calculate and record the thermal feed rate of all 
hazardous waste feedstreams by summing the products of each hazardous 
waste feed rate multiplied by the higher heating value of that 
hazardous waste;
    (D) Continuously calculate and record the total HAP thermal feed 
concentration for each constituent by dividing the HAP feedrate 
determined in paragraph (m)(2)(ii)(A) of this section by the thermal 
feed rate determined in paragraph (m)(2)(ii)(C) of this section for all 
hazardous waste feedstreams;
    (E) Interlock the HAP thermal feed concentration for each 
constituent with the AWFCO to stop hazardous waste feed when the 
thermal feed concentration exceeds the applicable thermal emission 
standard.
    (3) When you determine the feedrate of mercury, semivolatile 
metals, low volatile metals, or total chlorine and chloride for 
purposes of this provision, except as provided by paragraph (m)(4) of 
this section, you must assume that the analyte is present at the full 
detection limit when the feedstream analysis determines that the 
analyte in not detected in the feedstream.
    (4) Owners and operators of hazardous waste burning cement kilns 
and lightweight aggregate kilns may assume that mercury is present in 
raw material at half the detection limit when the raw material 
feedstream analysis determines that mercury is not detected.
    (5) You must state in the site-specific test plan that you submit 
for review and approval under paragraph (e) of this section that you 
intend to comply with the provisions of this paragraph. You must 
include in the test plan documentation that any surrogate that is 
proposed for gas flowrate adequately correlates with the gas flowrate.
