   1. The State's Submittal

      1. What rules did the State submit?

         Table 1 lists the rules addressed by this proposal with the dates that they were adopted by local air agencies and submitted by the Arizona Department of Environmental Quality (ADEQ).

         5/14/97 10/07/98. [Fugitive Dust].

         On June 4, 1996, the submittals of rules 4-2-020, 4-2-030, and 4-2- 040 were found to meet the completeness criteria in 40 CFR part 51, Appendix V, which must be met before formal EPA review. On April 24, 1999, the submittal of rule 4-2-050 was found to meet the completeness criteria.

      2. Are there other versions of these rules?

         There are no previous versions of Rules 4-2-020, 4-2-030, 4-2-040, or 4-2-050 in the SIP.

      3. What is the purpose of the submitted rules?

         Particulate matter (PM-10) harms human health and the environment. Section 110(a) of the CAA requires states to submit regulations that control PM-10 emissions. Rules 4-2-020, 4-2-030, 4-2-040, and 4-2-050 establish requirements that help control PM-10 emissions from fugitive dust. EPA's technical support document (TSD) has more information about these rules.

   2. EPA's Evaluation and Action

      1. How is EPA evaluating the rules?

      Generally, SIP rules must be enforceable (see section 110(a) of the CAA), must require reasonably available control measures (RACM), including reasonably available control technology (RACT) in moderate PM-10 nonattaiment areas (see section 189(a)), must require best available control measures (BACM), including best available control technology (BACT) in serious PM-10 nonattaiment areas (see section 189(b)), and must not relax existing requirements (see sections 110(l) and 193). A portion of PCAQCD is designated attainment, a portion is designated moderate nonattainment, and a portion is designated serious nonattainment for PM-10.

      The following guidance documents were used for reference:

1. Requirements for Preparation, Adoption, and Submittal of Implementation Plans, U.S. EPA, 40 CFR part 51.

2. PM-10 Guideline Document (EPA-452/R-93-008).

   2. Do the rules meet the evaluation criteria?

      These rules improve the SIP by establishing more stringent emission limits. These rules are largely consistent with the relevant policy and guidance regarding enforceability, RACT and SIP relaxations. Rule provisions which do not meet the evaluation criteria are summarized below and discussed further in the TSD.

   3. What are the rule deficiencies?

      These provisions conflict with section 110 and part D of the Act and prevent full approval of the SIP revision.

1. Rule 4-2-020, Section B specifies that Article 4 ``shall not be construed so as to prevent normal farm cultural practices which cause fugitive dust.'' Normal farm cultural practice is defined in Rule 4-2- 030, Definition 2, as ``all activities * * * conducted on any facility for the production of crops, livestock, poultry, livestock products or poultry products.'' As written, Rule 4-2-020, Section B effectively exempts agricultural activities from the fugitive dust rules without justification.

2. Rule 4-2-030, Definition 3, defines ``reasonable precaution'' in highly general terms. The term ``reasonable precaution'' is then used in every section of Rule 4-2-040, to define what actions must be taken to mitigate fugitive dust emissions from relevant activities. This general requirement is not sufficiently clear or enforceable.

3. Rule 4-2-050 does not contain recordkeeping provisions. The absence of these provisions makes the all of the submitted rules difficult to enforce.

   4. Proposed Action and Public Comment

      As authorized in sections 110(k)(3) and 301(a) of the Act, EPA is proposing a limited approval of the submitted

      [[Page 60936]]

      rules to improve the SIP. If finalized, this action would incorporate the submitted rules into the SIP, including those provisions identified as deficient. This approval is limited because EPA is simultaneously proposing a limited disapproval of the rules under section 110(k)(3). If this disapproval is finalized, sanctions will be imposed under section 179 of the Act unless EPA approves subsequent SIP revisions that correct the rule deficiencies within 18 months. These sanctions would be imposed according to 40 CFR 52.31. A final disapproval would also trigger the federal implementation plan (FIP) requirement under section 110(c). Note that the submitted rules have been adopted by the PCAQCD, and EPA's final limited disapproval will not prevent the local agency from enforcing them.

      We will accept comments from the public on the proposed limited approval and limited disapproval for the next 30 days.

      3. Statutory and Executive Order Reviews

   1. Executive Order 12866, Regulatory Planning and Review

      The Office of Management and Budget (OMB) has exempted this regulatory action from Executive Order 12866, entitled ``Regulatory Planning and Review.''

   2. Paperwork Reduction Act

      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.)

   3. Regulatory Flexibility Act

      The Regulatory Flexibility Act (RFA) generally requires an agency to conduct a regulatory flexibility analysis of any rule subject to notice and comment rulemaking requirements 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 not-for-profit enterprises, and small governmental jurisdictions.

      This rule will not have a significant impact on a substantial number of small entities because SIP approvals under section 110 and subchapter I, part D of the Clean Air Act do not create any new requirements but simply approve requirements that the State is already imposing. Therefore, because the Federal SIP approval does not create any new requirements, I certify that this action will not have a significant economic impact on a substantial number of small entities.

      Moreover, due to the nature of the Federal-State relationship under the Clean Air Act, preparation of flexibility analysis would constitute Federal inquiry into the economic reasonableness of state action. The Clean Air Act forbids EPA to base its actions concerning SIPs on such grounds. Union Electric Co., v. U.S. EPA, 427 U.S. 246, 255-66 (1976); 42 U.S.C. 7410(a)(2).

   4. Unfunded Mandates Reform Act

      Under sections 202 of the Unfunded Mandates Reform Act of 1995 (``Unfunded Mandates Act''), signed into law on March 22, 1995, EPA must prepare a budgetary impact statement to accompany any proposed or final rule that includes a Federal mandate that may result in estimated costs to State, local, or tribal governments in the aggregate; or to the private sector, of $100 million or more. Under section 205, EPA must select the most cost-effective and least burdensome alternative that achieves the objectives of the rule and is consistent with statutory requirements. Section 203 requires EPA to establish a plan for informing and advising any small governments that may be significantly or uniquely impacted by the rule.

      EPA has determined that the approval action proposed 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 proposes to approve 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.

   5. Executive Order 13132, Federalism

      Federalism (64 FR 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 distribution 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. 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 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 rule implementing a federal standard, and does not alter the relationship or the distribution of power and responsibilities established in the Clean Air Act. Thus, the requirements of section 6 of the Executive Order do not apply to this rule.

   6. Executive Order 13175, 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 proposed rule does not have tribal implications, as specified in Executive Order 13175. It will not have substantial direct effects on tribal governments, on the relationship between the Federal government and Indian tribes, or on the distribution of power and responsibilities between the Federal government and Indian tribes. Thus, Executive Order 13175 does not apply to this rule.

      EPA specifically solicits additional comment on this proposed rule from tribal officials.

   7. Executive Order 13045, Protection of Children from Environmental Health Risks and Safety Risks

      Protection of Children from Environmental Health Risks and Safety Risks (62 FR 19885, April 23, 1997), applies to any rule that: (1) Is determined to be ``economically significant'' as defined under Executive Order 12866, and (2) concerns an

      [[Page 60937]]

      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 does not involve decisions intended to mitigate environmental health or safety risks.

   8. Executive Order 13211, Actions that Significantly Affect Energy Supply, Distribution, or Use

      This rule is not subject to Executive Order 13211, ``Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use'' (66 FR 28355, May 22, 2001) because it is not a significant regulatory action under Executive Order 12866.

      1. National Technology Transfer and Advancement Act

      Section 12 of the National Technology Transfer and Advancement Act (NTTAA) of 1995 requires Federal agencies to evaluate existing technical standards when developing a new regulation. To comply with NTTAA, EPA must consider and use ``voluntary consensus standards'' (VCS) if available and applicable when developing programs and policies unless doing so would be inconsistent with applicable law or otherwise impractical.

      The EPA believes that VCS are inapplicable to this action. Today's action does not require the public to perform activities conducive to the use of VCS.
