Start Preamble

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Direct final rule.

SUMMARY:

EPA is taking direct final action to approve revisions to the Arizona Department of Environmental Quality (ADEQ) portion of the Arizona State Implementation Plan (SIP). These revisions concern procedures for the calculation of sulfur emissions from copper smelters. We are approving a local rule that helps regulate these emission sources under the Clean Air Act as amended in 1990 (CAA or the Act).

DATES:

This rule is effective on June 12, 2006 without further notice, unless EPA receives adverse comments by May 12, 2006. If we receive such comments, we will publish a timely withdrawal in the Federal Register to notify the public that this direct final rule will not take effect.

ADDRESSES:

Submit comments, identified by docket number EPA-R09-OAR-2006-0227, by one of the following methods:

I. The State's Submittal

A. What Rule Did the State Submit?

Table 1 lists the rule we are approving with the date that the amended rule became effective and was submitted by the ADEQ.

Table 1.—Submitted Rule

AgencyRule No.Rule titleAmended effectiveSubmitted
ADEQR18-2-Appendix 8Procedures for Utilizing the Sulfur Balance Method for Determining Sulfur Emissions07/18/0503/01/06
Start Printed Page 18625

ADEQ submitted this amended rule (final but not yet codified) originally on January 18, 2006 together with public hearing and State rulemaking documentation. On February 22, 2006, this rule submittal was found to meet the completeness criteria in 40 CFR part 51, appendix V, which must be met before formal EPA review. On March 1, 2006, ADEQ submitted the codified version of this final rule as a supplement to the original January 18, 2006 submittal.

B. Are There Other Versions of the Rule?

We approved a version of ADEQ Rule R18-2-Appendix 8 into the SIP on November 1, 2004 (69 FR 63321).

C. What Is the Purpose of the Submitted Rule Amendments?

Section 110(a) of the Clean Air Act (CAA) requires states to submit regulations that control volatile organic compounds, nitrogen oxides, particulate matter, sulfur oxides, and other air pollutants which harm human health and the environment. This rule was developed as part of the ADEQ's program to control sulfur oxides.

Rule R18-2-appendix 8 was granted a limited approval and limited disapproval on November 1, 2004. The deficiencies in Rule R18-2-appendix 8 that conflict with section 110 and part D of the CAA and prevented full approval of the rule are summarized below in the brackets, which are followed by the amendments made to correct the deficiencies:

  • [Sections A.8.1.2 and A.8.2 contain excessive Director's discretion by allowing the Director to approve an equivalent method to calculate the sulfur content without providing the criteria that will be used to determine approvability.] The amended rule corrects the deficiency by requiring the written approval by EPA in addition to the Director of alternative methods of obtaining sulfur content and removed sulfur.
  • [Sections A.8.1.2.1.1, A.8.1.2.1.2, and A.8.1.2.1.3 should clarify how a representative sample should be taken from belt feeders, railcars, and trucks so that the sampling process is not biased. ADEQ may wish to investigate possible ASTM methods or other industry sampling methods.] This recommendation by EPA for further clarification was optional, and the methods as stated along with the sample preparation methods in section A8.1.2.2 will be accepted.
  • [Sections A.8.1.2.3.1 and A.8.1.2.3.2 should provide specific test methods for the “barium sulfate” and “potassium iodine” procedures.] The amended rule corrects the deficiency by requiring specific test methods for barium sulfate and potassium iodide in section A8.4.3.
  • [Section A.8.2.5.5 should provide a specific test method for “chemical gravimetric means.” Apparently it is intended to be the “barium sulfate” method from section A.8.1.2.3.1. Also the accuracy is stated as +50%, but it should be a ± number. The accuracy of a gravimetric procedure is normally about ±1%, not ±50%.] The amended rule corrects the deficiency by requiring the barium sulfate gravimetric method in section A8.4.3 and states the required accuracy to be +/−50% instead of +50%. The actual accuracy is normally much better than +/−50%, but the lesser accuracy required is not cause to disapprove the rule.
  • [The reference in A8.3.1 should be changed from R18-2-715(C)(4) to R18-2-715.01(K)-(O). Also, the reference in A.8.3.2 should be changed from R18-2-715(c)(7)(v) to R18-2-715.01(Q).] The amended rule changes these references appropriately.

EPA's technical support document (TSD) has more information about this rule.

II. EPA's Evaluation and Action

A. How Is EPA Evaluating the Rule?

Generally, SIP rules must be enforceable (see section 110(a) of the CAA) and must not relax existing requirements (see sections 110(1) and 193). There are no specific reasonably available control measures (RACM) or best available control measures (BACM) for administrative rules.

Guidance and policy documents that we used to help evaluate specific enforceability and RACT requirements consistently include the following:

  • Requirements for Preparation, Adoption, and Submittal of Implementation Plans, U.S. EPA, 40 CFR part 51.
  • Guidance Document for Correcting Common VOC & Other Rule Deficiencies, EPA Region IX (August 21, 2001). (The Little Bluebook)

B. Do the Rule Amendments Meet the Evaluation Criteria?

We believe the rule is consistent with the relevant policy and guidance regarding enforceability, SIP relaxations, BACM, and RACM. We also believe that the submitted rule adequately addresses the deficiencies identified in our November 1, 2004 limited disapproval. The TSD has more information on our evaluation.

C. Public Comment and Final Action

As authorized in section 110(k)(3) of the CAA, EPA is fully approving the submitted ADEQ Rule R18-2-Appendix 8 because we believe it fulfills all relevant requirements. We do not think anyone will object to this approval, so we are finalizing it without proposing it in advance. However, in the Proposed Rules section of this Federal Register, we are simultaneously proposing approval of the same submitted rule. If we receive adverse comments by May 12, 2006, we will publish a timely withdrawal in the Federal Register to notify the public that the direct final approval will not take effect and we will address the comments in a subsequent final action based on the proposal. If we do not receive timely adverse comments, the direct final approval will be effective without further notice on June 12, 2006. This will incorporate this rule into he federally enforceable SIP and permanently terminate all sanctions and FIP implications of our 2004 limited disapproval.

III. Statutory and Executive Order Reviews

Under Executive Order 12866 (58 FR 51735, October 4, 1993), this action is not a “significant regulatory action” and therefore is not subject to review by the Office of Management and Budget. For this reason, this action is also not subject to Executive Order 13211, “Actions Concerning Regulations That Significantly Affect Energy Supply Distribution, or Use” (66 FR 28355, May 22, 2001). This action merely approves state law as meeting Federal requirements and imposes no additional requirements beyond those imposed by state law. Accordingly, the Administrator certifies that this rule will not have a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.). Because this rule approves pre-existing requirements under state law and does not impose any additional enforceable duty beyond that required by state law, it 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).

This rule also does not have tribal implications because it will not have a substantial direct effect on one or more Indian tribes, on the relationship between the Federal Government and Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes, as specified by Executive Order 13175 Start Printed Page 18626(65 FR 67249, November 9, 2000). This action also does not have federalism implications because it 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 (64 FR 43255, August 10, 1999). This action merely approves a state rule implementing a Federal standard, and does not alter the relationship or the distribution of power and responsibilities established in the Clean Air Act. This rule also is not subject to Executive Order 13045 “Protection of Children from Environmental Health Risks and Safety Risks” (62 FR 19885, April 23, 1997), because it is not economically significant.

In reviewing SIP submissions, EPA's role is to approve state choices provided that they meet the criteria of the Clean Air Act. In this context, in the absence of a prior existing requirement for the State to use voluntary consensus standards (VCS), EPA has no authority to disapprove a SIP submission for failure to use VCS. It would thus be in-consistent with applicable law for EPA, when it reviews a SIP submission, to use VCS in place of a SIP submission that otherwise satisfies the provisions of the Clean Air Act. This, the requirements of section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) do not apply. This rule does not impose an information collection burden under the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.).

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 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).

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 12, 2006. 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).)
