The EPA is approving by direct final rulemaking the Oklahoma Department of Environmental Quality's (ODEQ) request for program approval of adequate authorities and resources to implement and enforce Federal National Emission Standards for Hazardous Air Pollutants (NESHAP) in 40 CFR parts 61 and 63, as these regulations apply to non-part 70 sources.
The EPA is approving ODEQ's mechanism for receiving delegation of unchanged NESHAPs as they apply to non-part 70 sources.
Also, EPA is delegating authority to ODEQ to implement and enforce certain Federal NESHAPs hazardous air pollutant regulations which ODEQ has adopted by reference into their State rules as they apply to all sources (i.e., both part 70 and non-part 70 sources). These are NESHAPs found in 40 CFR parts 61 and 63. The EPA is also delegating specified General Provisions to parts 61 and 63 as these regulations apply to all sources.
The EPA is waiving its notification requirements so sources will only need to send notifications and reports to ODEQ.
This action is taken under the authority of CAA section 112(l) and 40 CFR part 63, subpart E.
This action does not apply to areas in Indian Country over which the State of Oklahoma has not demonstrated authority.
Written comments on this action should be addressed to Mr. Robert M. Todd at the Region 6 office listed below. Copies of the requests for delegation and other supporting documentation are available for public inspection at the following location: U.S. Environmental Protection Agency, Region 6, Multimedia Planning and Permitting Division (6PD), 1445 Ross Avenue, Dallas, TX 75202-2733. Anyone wanting to examine these documents should make an appointment at least two working days in advance.

8. What is the history of ODEQ's delegation requests?
We, the EPA, are approving ODEQ's air toxics program for non-part 70 sources and their mechanism for receiving future delegation of unchanged Federal NESHAP regulations for non-part 70 sources. The State submittal meets all section 112(l) requirements because:
The State program is no less stringent than the Federal program. The ODEQ's rules at Oklahoma Administrative Code, subchapter 41, Control of Emissions of Hazardous and Toxic Air Contaminants, part 3, Hazardous Air Contaminants, section 252:100-41-15, adopt certain Federal NESHAP regulations by reference, as more fully discussed in this action.
The ODEQ has demonstrated adequate authority and resources to implement and enforce the standards.
The schedule for implementation and compliance is sufficiently expeditious.
The program otherwise complies with Federal guidance.
A more detailed analysis of the State's submittal pursuant to § 63.91 is in the Technical Support Document included in the docket of this rulemaking. The mechanism for future delegation of unchanged standards is described in question twelve below.
We are delegating:
We are approving ODEQ's request for delegation of authority to implement and enforce specific 40 CFR parts 61 and 63, subparts for all sources, as they exist July 1, 1999. A notable exception is that we are not delegating those standards under part 61 dealing with radionuclides.
(Two tables outlining the standards requested by ODEQ and delegated by this action are found under the response to question eight, below.)
We are approving in part ODEQ's request for delegation of authority to implement and 40 CFR part 61, subpart A and part 63, subpart A, General Provisions (for all sources). The ODEQ's rules are unchanged from the Federal provisions.
We have determined that ODEQ has sufficient resources and expertise to implement certain sections of the General Provisions. A July 10, 1998, memorandum from John Seitz [1] clarified which of the part 63 General Provisions authorities may be delegated to State agencies. On September 14, 2000 our rules were revised to outline the delegable authorities at 40 CFR 63.91(g). A guidance document[2] from EPA's Office of Enforcement and Compliance clarified the part 61 discretionary authorities which were appropriate to delegate to State agencies. Granting ODEQ authority to make decisions that are not likely to be nationally significant or which do not alter the stringency of the underlying standard is in keeping with these authorities. The ODEQ should make decisions on a source-by-source basis, not on a source category basis.
Listed below are the part 61, subpart A, sections that we cannot delegate to ODEQ. We are delegating all other part 61, General Provision authorities to ODEQ.
40 CFR Part 61, Subpart A, General Provisions, Authorities Which May Not Be Delegated
61.04(b) Addresses of State and Local Implementing Agencies.
61.12(d)(1) Compliance with Standards and Maintenance Requirements, Alternate Means of Emission Limitation.
61.13(h) Major Change to an Emissions Test.
61.14(g) Major modifications to Monitoring Requirements.
61.16 Availability of Information Procedures.
Listed below are the part 63, subpart A, sections that we are delegating to ODEQ. Also, listed in the footnotes of the part 63 delegation table at the end of this rule are the authorities that cannot be delegated to any State or local agency which we therefore retain.
Part 63, Subpart A, General Provisions Authorities Delegated to ODEQ
63.7(e)(2)(iv) and (h)(2), (h)(3) Waiver of Performance Testing.
63.9 and 63.10 Approval of Adjustments to Time Periods for Submitting Reports.
63.10(f) Approval of Minor Alternatives to Recordkeeping and Reporting.
For part 70 sources, semiannual and annual reports are required and this does not change that requirement. Decisions ODEQ makes, such as State applicability determinations, approval of alternatives to test methods, approval of alternatives to monitoring and approval of alternatives to recordkeeping requirements are not binding on EPA.
In 1982, the Administrator of EPA's Dallas Regional Office delegated some authority to implement and enforce New Source Performance Standards (NSPS) and NESHAPs to ODEQ. (47 FR 17285, April 22, 1982) These standards and authorities are found in 40 CFR parts 60 and 61, respectively. Today's action will rescind and replace the NESHAP portion of that agreement only. The NSPS portion of the 1982 delegation agreement as supplemented on October 8, 1999 is not affected by this rulemaking. This delegation will cover more part 61 standards, more sources, and grant more discretionary authority to ODEQ, as discussed in the General Provision section of this document.
Section 112(l) of the CAA enables EPA to approve State air toxics programs or rules to operate in place of the Federal air toxics program or rules. 40 CFR part 63, subpart E (65 FR 55810 September 14, 2000) governs EPA's approval of State rules or programs under section 112(l).
Approval of an air toxics program is granted by EPA if we find that:
(1) The State program is “no less stringent” than the corresponding Federal program or rule,
(2) The State has adequate authority and resources to implement the program,
(4) The program otherwise complies with Federal guidance. Any request for subpart E approval that does not change the Federal section 112 rules must meet the criteria in 40 CFR 63.91.
The request may specify the mechanism that the State will use in the future to receive delegation of unchanged Federal section 112 standards without additional Federal rulemaking.
The procedure and criteria for requesting and receiving approval of programs or requesting delegation under section 112(l) of the CAA was initially published on November 26, 1993 in 58 FR 62262. The regulations were codified at 40 CFR part 63, subpart E. The EPA's procedures for delegating NESHAPS were modified on September 14, 2000 in 65 FR 55810. The revisions were to provide more options and expedite the approval process. These revisions did not affect the criteria and procedures for program approval and straight delegation to Oklahoma, and the State's request and our review is consistent with the regulations as revised.
With this delegation, ODEQ has the primary responsibility to implement and enforce the delegated standards.
This action does not apply to areas of Indian Country over which the State of Oklahoma has not demonstrated authority. States do not have jurisdiction over Indian Country (as defined in 18 U.S.C. 1151, and referenced in 40 CFR 51.1(i)) unless specifically granted by Congress. Since the State of Oklahoma has not submitted a demonstration of authority over the Indian Country, we are limiting our approval to those areas that do not constitute Indian Country. For a more detailed discussion of Tribal authority under the Act, see 59 FR 43956, August 25, 1994 and 63 FR 7254, February 12, 1998.
We retain the right, as allowed by CAA section 112(l)(7), to enforce any applicable emission standard or requirement under section 112.
The EPA Administrator has the authority to approve certain changes to, or make decisions under the General Provisions to parts 61 and 63. This authority is in 40 CFR part 61, subpart A and 40 CFR part 63, subpart A. We are granting ODEQ some of these authorities, and retaining others, as explained with the General Provisions description. And as stated earlier, EPA is not bound by State determinations.
In addition, no authorities are delegated that require rulemaking in the Federal Register to implement, or where Federal overview is the only way to ensure national consistency in the application of the standards or requirements of CAA section 112.
Also, we retain any authority in an individual emission standard that may not be delegated according to provisions of the standard.
The EPA must oversee ODEQ's decisions to ensure the delegated authorities are being adequately implemented and enforced. We will integrate oversight of the delegated authorities into the existing mechanisms and resources for oversight currently in place.
If, during oversight, we determine that ODEQ made decisions that decreased the stringency of the delegated standards, then ODEQ should take corrective actions and the source(s) affected by the decisions would be notified. We will initiate withdrawal of the program if the corrective actions taken are insufficient.
On March 10, 1995, we proposed to approve the State's program and mechanism for gaining delegation of unchanged section 112 standards for part 70 sources (60 FR 13092). This was included in our proposal to approve ODEQ's request for interim approval of the part 70 Operating Permit Program. On February 5, 1996, we issued final approval of the State's air toxics program and delegation mechanism for all section 112 standards under the authority of CAA section 112(1)(5) and 40 CFR 63.91 (61 FR 4224). This applies only to sources covered by the part 70 program. Start Printed Page 1587
We received delegation requests from ODEQ dated June 26, 1998, and May 5, 2000. These requests are for delegation of the 40 CFR parts 61 and 63 NESHAP standards adopted unchanged into Oklahoma Administrative Code Title 252 Chapter 100 Air Pollution Control Subchapter 41 Control of Emission of Hazardous and Toxic Air Contaminants. The ODEQ requested delegation of the general provisions and emission standards listed in the tables below. These requests were made according to the requirements of 40 CFR part 63, subpart E. 58 FR 62262, November 26, 1993. This regulation, which governs EPA's approval of State rules or programs was recently revised to better serve the needs of State and Local agencies that want to implement NESHAPs in their areas. 65 FR 55810, September 14, 2000. These revisions did not affect the criteria and procedures for program approval and straight delegation to Oklahoma, and the State's request and our review is consistent with the regulations as revised.

The State has asked for delegation of these standards, and we are delegating them to ODEQ, as they existed on July 1, 1999. Please see question twelve below for a discussion of how we will delegate future standards and revisions to the State.
Certain General Provisions authorities are automatically granted to ODEQ as part of their part 70 Operating Permits Program approval (regardless of whether the Operating Permits Program approval is interim or final). These are 40 CFR 63.6(i)(1), “Extension of Compliance with Emission Standards,” and 63.5(e) and (f), “Approval and Disapproval of Construction and Reconstruction.”[3]
Additionally, ODEQ's authority to grant a source a compliance extension under 40 CFR 63.6(i)(1) is not limited to delegated standards or part 70 permitted sources.
Sources within ODEQ's jurisdiction must submit notifications and reports required by the delegated NESHAPs to ODEQ, and sources do not need to send a copy to EPA. The ODEQ is the primary point of contact with respect to delegated NESHAPs. EPA Region 6 waives the requirement that notifications and reports for delegated standards be submitted to EPA in addition to ODEQ per 40 CFR 63.9(a)(4)(ii) and 63.10(a)(4)(ii).
In delegating the authority to implement and enforce these rules and in granting a waiver of EPA notification requirements, we require ODEQ to input all source information into the Aerometric Information Retrieval System (AIRS) for both point and area sources. The ODEQ must enter this information into the AIRS system and update the information by September 30 of every year. Additionally, ODEQ must also report to EPA, Region 6, all MACTRAX information on our request, which is typically semiannually. (MACTRAX provides summary data for each implemented NESHAP that EPA uses to evaluate the Air Toxics Program.) The ODEQ must provide any additional compliance related information to EPA, Region 6, Office of Compliance Assurance as necessary.
In receiving delegation for specific General Provisions authorities, ODEQ must submit to EPA, Region 6, copies of determinations issued under these authorities. For part 61, these determinations include: applicability determinations (section 61.01); determinations of construction or modification (section 61.06); approvals of construction or modification (section 61.08); Waiver of Compliance (section 61.11); Operation and Maintenance Requirements (section 61.12(c)); Waiver of Emission Test (section 61.13(h)(1)(iii) and (i)(1), (2)); Approval of Minor Alternatives to Monitoring (section 61.14(g) except section 61.14(g)(1)(ii)). For part 63, these determinations include: applicability determinations (§ 63.1); approval/disapprovals of construction and reconstruction (§ 63.5(e) and (f)); approval/disapprovals of compliance extensions (§ 63.6(i)(1)); approval of shorter sampling times and volumes (§ 63.7(e)(2)(iii)); waiver of performance testing (§ 63.7(e)(2)(iv) and (h)(2), (3)); approval of adjustments to time periods for submitting reports (§§ 63.9 and 63.10); approvals/disapprovals of minor (§ 63.7(e)(2)(i)) or intermediate (§ 63.7(e)(2)(ii) and (f)) alternative test methods; approvals/disapprovals of minor or intermediate alternative monitoring methods (§ 63.8(f)); and approvals/disapprovals of minor alternatives to recordkeeping and reporting (§ 63.10(f)). The ODEQ must also forward to EPA, Region 6, copies of any notifications received under § 63.6(h)(7)(ii) regarding the use of a continuous opacity monitoring system.
Additionally, EPA's Emission Measurement Center of the Emissions Monitoring and Analysis Division must receive copies of any approved intermediate changes to test methods or monitoring. (Please note that intermediate changes to test methods must be demonstrated as equivalent through the procedures set out in EPA method 301.) This information on approved intermediate changes to test methods and monitoring will be used to compile a database of decisions that will be accessible to State and local agencies and EPA Regions for reference in making future decisions. (For definitions of major, intermediate and minor alternative test methods or monitoring methods, see 40 CFR 63.90). The ODEQ should forward these intermediate test methods or monitoring changes via mail or facsimile to: Chief, Source Categorization Group A, U.S. EPA (MD-19), Research Triangle Park, NC 27711, Facsimile telephone number: (919) 541-1039.
In the future, for all sources, ODEQ will only need to send a letter of request to EPA, Region 6, for those NESHAP regulations that the State has adopted by reference with proof of its regulatory authority. We will respond in writing to the request stating that the request for delegation is either granted or denied. If a request is approved, the effective date of the delegation will be the date of our response letter. A document of the delegation will be published in the Federal Register to inform the public and affected sources of the delegation Start Printed Page 1589and to indicate where source notifications and reports should be sent.
Furthermore, ODEQ intends to update their adoptions by reference of 40 CFR parts 61 and 63 standards and request updated delegation annually, as current standards are revised and new standards are promulgated.
As part of today's rule, we are delegating, under the CAA, implementation and enforcement authority for the Hazardous Waste Combustor MACT to ODEQ. Many of the sources subject to the HWC MACT are also subject to the RCRA permitting requirements. We expect air emissions and related operating requirements found in the HWC MACT will be included in part 70 permits issued by ODEQ. However, RCRA permits will still be required for all other aspects of the combustion unit and the facility that are governed by RCRA (e.g., corrective action, general facility standards, other combustor-specific concerns such as materials handling, risk-based emissions limits and operating requirements, as appropriate and other hazardous waste management units).[4] See the HWC MACT rule preamble discussion on the interrelationship of the MACT rule with the RCRA Omnibus provision and site specific risk assessments at 64 FR 52828, pages 52839-52843, September 30, 1999, and the RCRA Site-Specific Risk Assessment Policy for Hazardous Waste Combustion Facilities dated June, 2000 for more information.
The public was provided the opportunity to comment on the proposed approval of the program and mechanism for delegation of section 112 standards, as apply to part 70 sources, on March 10, 1995. 60 FR 13088. The EPA received public comments on that proposal and responded to them in the February 5, 1996, Federal Register. 61 FR 4220. In this action, the public is given an opportunity to comment on the program and mechanism for the State to gain delegation of these standards as they apply to non-part 70 sources. However, the Agency views the approval of these requests as a noncontroversial action and anticipates no adverse comments. Therefore, EPA is publishing this rule without prior proposal. However, in the Proposed Rules section of today's Federal Register publication, EPA is publishing a separate document that will serve as the proposal to approve the program and delegation of authority described in this action if adverse comments are received. This action will be effective March 9, 2001 without further notice unless the Agency receives relevant adverse comments by February 7, 2001.
If EPA receives adverse comments, we will publish a timely withdrawal in the Federal Register informing the public the rule will not take effect. We 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.
Protection of Children from Environmental Health Risks and Safety Risks (62 Federal Register 19885, April 23, 1997), applies to any rule that: (1) Is determined to be “economically significant” as defined under Executive Order 12866, and (2) concerns an environmental health or safety risk that EPA has reason to believe may have a disproportionate effect on children. If the regulatory action meets both criteria, 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.
This rule is not subject to Executive Order 13045 because it is not economically significant and does not involve decisions intended to mitigate environmental health or safety risks.
Federalism (64 Federal Register 43255, August 10, 1999) revokes and replaces Executive Orders 12612 (Federalism) and 12875 (Enhancing the Intergovernmental Partnership). Executive Order 13132 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 Start Printed Page 1590distribution of power and responsibilities among the various levels of government.” Under Executive Order 13132, EPA may not issue a regulation that has federalism implications, that imposes substantial direct compliance costs, and that is not required by statute, unless the Federal government provides the funds necessary to pay the direct compliance costs incurred by State and local governments, or EPA consults with State and local officials early in the process of developing the proposed regulation. The EPA also may not issue a regulation that has federalism implications and that preempts State law unless the Agency consults with State and local officials early in the process of developing the proposed regulation.
This rule does not have federalism implications. It will not have substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132, because it merely approves a State program and rules implementing a Federal standard, and does not alter the relationship or the distribution of power and responsibilities established in the CAA. Thus, Executive Order 13132 does not apply to this rule. Although section 6 of the Executive Order does not apply to this rule, EPA did consult with State officials in developing this rule, and this rule is in response to the State's delegation request.
This rule will not have a significant impact on a substantial number of small entities because delegation of authority to implement and enforce unchanged Federal standards under section 112(l) of the CAA does not create any new requirements, but simply transfers primary implementation authorities to the State. Therefore, because this action does not impose any new requirements, the Administrator certifies that this action will not have a significant economic impact on a substantial number of small entities.
The EPA has determined that the approval action promulgated does not include a Federal mandate that may result in estimated costs of $100 million or more to either State, local, or tribal governments in the aggregate, or to the private sector. This Federal action approves pre-existing requirements under State or local law, and imposes no new requirements. Accordingly, no additional costs to State, local, or tribal governments, or to the private sector, result from this action.
This rule does not involve special consideration of Environmental Justice related issues as required by Executive Order 12898 (59 FR 7629, February 16,1994).
The EPA has complied with Executive Order 12630 (53 FR 8859, March 15, 1988) by examining the takings implications of the rule in accordance with the “Attorney Generals Supplemental Guidelines for the Evaluation of Risk and Avoidance of Unanticipated Takings” issued under the Executive Order.
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. 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 rule will be effective March 12, 2001 unless EPA receives adverse written comments by February 8, 2001.
Under section 307(b)(1) of the CAA, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by March 12, 2001. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this rule 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 enforce its requirements. (See section 307(b)(2).)
Title 40, chapter I, part 63 of the CFR is amended as follows:
2. Section 63.99 is amended by adding paragraph (a)(36) to read as follows:

4. EPA promulgated the HWC MACT (40 CFR part 63, subpart EEE) under the joint authority of the (CAA) and (RCRA). Before this rule went in to effect, the air emissions from these sources were primarily regulated under the authority of RCRA. See 40 CFR parts 264, 265, 266, and 270. With the release of HWC MACT, the air emissions are now regulated under both CAA and RCRA. Even though both statutes give EPA the authority, we determined that having the emissions standards and permitting requirements in both sets of implementing regulations would be duplicative. For this reason, using the authority provided by section 1006(b) of RCRA, EPA deferred the RCRA requirements for the HWC emission controls to the CAA requirements of 40 CFR part 63, subpart EEE. After a facility has demonstrated compliance with the HWC MACT, the RCRA waste management standards for air emissions from these units will no longer apply, with the exception of 3005(c)(3) of RCRA, which requires that each RCRA permit contain the terms and conditions necessary to protect human health and the environment. Under this provision of RCRA, if a regulatory authority determines that more stringent conditions that the HWC MACT are necessary to protect human health and the environment for a particular facility, then that regulatory authority may impose those conditions in the facility's RCRA permit.
