Approval and Promulgation of Implementation Plans; California State Implementation Plan Revision, Six California Air Pollution Control Districts

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

SUMMARY: EPA is taking direct final action on revisions to the California State Implementation Plan. The revisions concern rules from the following: Kern County Air Pollution Control District (KCAPCD), Lake County Air Quality Management District (LCAQMD), Modoc County Air Pollution Control District (MCAPCD), Northern Sierra Air Quality Management District (NSAQMD), San Joaquin Valley Unified Air Pollution Control District (SJVUAPCD), and Ventura County Air Pollution Control District (VCAPCD). The rules control particulate matter (PM) emissions from open burning, orchard heaters, fuel burning equipment, or processes identified by a weight rate throughput. This approval action will incorporate these rules into the federally-approved SIP. The intended effect of approving these rules is to regulate emissions of PM in accordance with the requirements of the Clean Air Act, as amended in 1990 (CAA). Thus, EPA is finalizing the approval of these rules into the California SIP under provisions of the CAA regarding EPA action on SIP submittals, SIPs for national primary and secondary ambient air quality standards, and plan requirements for attainment and nonattainment areas.

DATES: This rule is effective on July 19, 1999 without further notice, unless EPA receives relevant adverse comments by June 17, 1999. If EPA receives such comments, then it will publish a timely withdrawal in the Federal Register informing the public that this rule will not take effect.

ADDRESSES: Comments must be submitted to Andrew Steckel at the Region IX office listed below. Copies of the rules and EPA's evaluation report for the rules are available for public inspection at EPA's Region IX office during normal business hours. Copies of the submitted rules are available for inspection at the following locations:

   [[Page 26877]]

   1994); and VCAPCD Rule 56, Open Fires (as amended on March 29, 1994, submitted May 24, 1994).

2. Background

   On March 3, 1978, EPA promulgated a list of total suspended particulate (TSP) nonattainment areas under the provisions of the 1977 Clean Air Act, that included the Ventura County (Southern Part) and the San Joaquin Valley Air Basin (43 FR 8964; 40 CFR 81.305). On July 1, 1987 (52 FR 24672) EPA replaced the TSP standards with new PM standards applying only to PM up to 10 microns in diameter (PM-10). ‹SUP›1‹/SUP› On November 15, 1990, amendments to the 1977 CAA were enacted (Pub. L. 101-549, 104 Stat. 2399, codified at 42 U.S.C. 7401-7671q). On the date of enactment of the 1990 CAA Amendments, PM-10 areas meeting the qualifications of section 107(d)(4)(B) of the Act were designated nonattainment by operation of law and classified as moderate or serious pursuant to section 188(a). Nevada County, Plumas County, and Sierra County (which now comprise NSAQMD), Lake County, Modoc County, and Ventura County were not among the areas designated nonattainment. The present KCAPCD includes an area never designated nonattainment for PM- 10 and a part of Searles Valley, which was designated moderate nonattainment for PM-10. On February 8, 1993, EPA classified four nonattainment areas as serious nonattainment, including the San Joaquin Valley Planning Area, which now comprises the SJVUAPCD.

   \1\ On July 18, 1997 EPA promulgated revised and new standards for PM-10 and PM-2.5 (62 FR 38651). EPA has not yet established specific plan and control requirements for the revised and new standards. This action is part of California's efforts to achieve compliance with the 1987 PM-10 standards.

   Section 189(a) of the CAA requires moderate and above PM-10 nonattainment areas to adopt reasonably available control measures (RACM), including reasonably available control technology (RACT) for stationary sources of PM-10. Section 189(b) of the CAA requires serious nonattainment areas to adopt best available control measures (BACM) for significant sources of PM-10, including best available control technology (BACT). Therefore, KCAPCD and SJVUAPCD must meet RACM. SJVUAPCD must also adopt BACM. However, EPA is deferring decision on the specific BACM requirements until EPA acts on SJVUAPCD's BACM plan at a later date.

   In response to section 110(a) and Part D of the Act, the State of California submitted many PM-10 rules for incorporation into the California SIP, including the rules being acted on in this document. This document addresses EPA's direct-final action for the following:

   KCAPCD Rule 409, Fuel Burning Equipment, was amended May 7, 1998, submitted by the State of California for incorporation into the SIP on June 23, 1998, and found to be complete on August 24, 1998, pursuant to EPA's completeness criteria that are set forth in 40 CFR Part 51 Appendix V ‹SUP›2‹/SUP› and is being finalized for approval into the SIP.

   \2\ EPA adopted the completeness criteria on February 16, 1990 (55 FR 5830) and, pursuant to section 110(k)(1)(A) of the CAA, revised the criteria on August 26, 1991 (56 FR 42216).

   LCAQMD Sections (Rules) 248.5, 270, 640, 1010, and 1350 were adopted December 6, 1988, December 6, 1988, July 15, 1997, June 13, 1989, and October 15, 1996, respectively; submitted by the State of California for incorporation into the SIP on February 7, 1989, February 7, 1989, March 10, 1998, March 26, 1990, and March 10, 1998, respectively; and found to be complete on May 5, 1989, May 5, 1989, May 21, 1998, June 20, 1990, and May 21, 1998, respectively.

   LCAQMD Section (Rule) 1002 was amended March 19, 1996, submitted May 18, 1998, and found to be complete July 17, 1998.

   MCAPCD Rule 4.11, Orchard Heaters, was adopted January 3, 1989, submitted by the State of California for incorporation into the SIP on December 31, 1990, and found to be complete on February 28, 1991.

   NSAQMD Rule 211, Process Weight per Hour, was adopted September 11, 1991, submitted by the State on October 28, 1996, and found to be complete on December 19, 1996.

   SJVUAPCD Rule 4301, Fuel Burning Equipment, was amended December 17, 1992, submitted by the State of California for incorporation into the SIP on September 28, 1994, and found to be complete on October 21, 1994.

   VCAPCD Rule 56, Open Fires was amended March 29, 1994, submitted by the State of California for incorporation into the SIP on May 24, 1994, and found to be complete on July 14, 1994.

   PM emissions can harm human health and the environment. These rules were adopted as part of KCAPCD, LCAQMD, MCAPCD, NSAQMD, SJVUAPCD, and VCAPCD efforts to maintain the National Ambient Air Quality Standard (NAAQS) for TSP/PM-10. The following is EPA's evaluation and final action for these rules.

3. EPA Evaluation and Action

   In determining the approvability of a PM-10 rule, EPA must evaluate the rule for consistency with the requirements of the CAA and EPA regulations, as found in section 110 and part D of the CAA and 40 CFR part 51 (Requirements for Preparation, Adoption, and Submittal of Implementation Plans). EPA must also ensure that rules are enforceable and strengthen or maintain the SIP's control strategy.

   The statutory provisions relating to RACM/RACT and BACM/BACT are discussed in EPA's ``General Preamble'', which give the Agency's preliminary views on how EPA intends to act on SIPs submitted under Title I of the CAA. See 57 FR 13498 (April 16, 1992), 57 FR 18070 (April 28, 1992) and 59 FR 41998 (August 16, 1994). In this rulemaking action, EPA is applying these policies to this submittal, taking into consideration the specific factual issues presented.

   EPA previously reviewed rules from KCAPCD, LCAQMD, MCAPCD, NSAQMD, SJVUAPCD, and VCAPCD and incorporated them into the federally-approved SIP pursuant to section 110(k)(3) of the CAA.

   On September 22, 1972 and May 3, 1984, respectively, EPA approved into the SIP versions of KCAPCD Rule 407.2, Fuel Burning Equipment-- Combustion Contaminants, and Rule 409, Fuel Burning Equipment--Desert Basin. Submitted Rule 409, Fuel Burning Equipment, combines these two rules and is equally as stringent. This rule regulates particulate and other emissions from fuel burning equipment. EPA has determined that submitted Rule 409 meets the requirements of RACM.

   On May 18, 1981, EPA approved into the Nevada County (now part of the unified NSAQMD) SIP Rule 211, Process Weight per Hour, the general prohibition plus exceptions in paragraphs A.6 and A.7, while disapproving the exceptions in paragraphs A.1 through A.5. Paragraphs A.1 through A.5 exceptions give specific emission limits to the following:

   ‹bullet› Portland Cement Kilns--0.30 pounds per ton dry feed.

   ‹bullet› Portland Cement Clinker Coolers--0.10 pounds per ton dry feed.

   ‹bullet› Sewage Sludge Incinerators--1.30 pounds per ton dry sludge input.

   ‹bullet› Rotary Lime Kilns--0.30 pounds per ton limestone feed.

   ‹bullet› Lime Hydrators--0.15 pounds per ton lime feed.

   There is currently no version of NSAQMD Rule 211 in Plumas County or Sierra County in the SIP. Submitted NSAQMD Rule 211, Process Weight per

   [[Page 26878]]

   Hour, which contains the general prohibition plus paragraphs A.1 through A.6., replaces the Nevada County SIP-approved rule. The previously disapproved paragraphs A.1 through A.5 are being approved in this action, because this is an attainment area and all of the exceptions are at least as stringent as New Source Performance Standards, and EPA concludes that they will not interfere with attainment or any other provision of the CAA.

   There is currently no version of LCAQMD Section (Rule) 248.5, Prescribed Burning (Definition), and LCAQMD Section (Rule) 270, Wildland Vegetation Management Burning (Definition), in the SIP. Section (Rule) 248.5 defines Prescribed Burning. Section (Rule) 270 defines Wildland Vegetation Management Burning.

   There is currently no version of LCAQMD Section (Rule) 640, (Permit Exemptions) in the SIP. This is a new rule (a previous version was not SIP-approved) that exempts certain types of burning from the requirement to obtain a burn permit.

   On August 4, 1978, EPA approved into the SIP a version of LCAQMD Section (Rule) 1002, (Agencies Authorized to Issue Permits). Submitted Section (Rule) 1002, replaces the SIP-approved rule and includes the following significant changes from the current SIP:

   ‹bullet› U.S. Forest Service is deleted as an agency authorized to issue burn permits.

   ‹bullet› The specific California Division of Forestry and local fire protection districts are listed by name.

   There is currently no version of LCAQMD Section (Rule) 1010, (No- Burn Day) in the SIP. This is a new rule that states that the Air Pollution Control Officer shall designate and provide notice of No-Burn Days, in order to protect ambient air quality.

   There is currently no version of LCAQMD Section (Rule) 1350, Burning of Standing Tule, in the SIP. This is a new rule that regulates the burning of standing tule and requires a burn permit.

   There is currently no version of MCAPCD Rule 4.11, Orchard Heaters, in the SIP. The submitted rule includes the following provisions:

   ‹bullet› Restricts the use of orchard heaters to those approved by the California Air Resources Board.

   ‹bullet› Limits the emissions to not more than one gram per minute of unconsumed solid carbonaceous material.

   On various dates, EPA approved into the SIP versions of Fuel Burning Equipment rules for the eight counties that now comprise the SJVUAPCD. Submitted Rule 4301, Fuel Burning Equipment, replaces these rules and includes no significant changes from the SIP versions from the eight counties. Rule 4301 is equally as stringent as similar rules in other districts. EPA has determined that submitted Rule 4301 meets the requirements of RACM.

   On August 6, 1990, EPA approved into the SIP a version of VCAPCD Rule 56, Open Fires. Submitted VCAPCD Rule 56, Open Fires, replaces this rule and includes the following significant changes from the current SIP:

   ‹bullet› Burning is prohibited on Ban Days, which have been redefined as days when the ambient ozone concentration is or is predicted to exceed the California ozone standard of 0.09 ppm by volume.

   ‹bullet› Persons who burn agricultural waste are now required to notify the District both before and after burning occurs.

   EPA has evaluated the submitted rules and has determined that they are consistent with the CAA, EPA regulations, and EPA policy. Therefore, the following rules are being approved under section 110(k)(3) of the CAA as meeting the requirements of section 110(a) and part D:

   ‹bullet› KCAPCD Rule 409, Fuel Burning Equipment (submitted June 23, 1998).

   ‹bullet› LCAQMD Section (Rule) 248.5, Prescribed Burning (Definition) (submitted February 7, 1989).

   ‹bullet› LCAQMD Section (Rule) 270, Wildland Vegetation Management Burning (Definition) (submitted February 7, 1989).

   ‹bullet› LCAQMD Section (Rule) 640, (Permit Exemptions) (submitted March 10, 1998).

   ‹bullet› LCAQMD Section (Rule) 1002, (Agencies Authorized to Issue Permits) (submitted May 18, 1998).

   ‹bullet› LCAQMD Section (Rule) 1010, (No-Burn Day) (submitted March 26, 1990).

   ‹bullet› LCAQMD Section (Rule) 1350, Burning of Standing Tule (submitted March 10, 1998).

   ‹bullet› MCAPCD Rule 4.11, Orchard Heaters (submitted December 31, 1990).

   ‹bullet› NSAQMD Rule 211, Process Weight per Hour (submitted October 28, 1996).

   ‹bullet› SJVUAPCD Rule 4301, Fuel Burning Equipment (submitted September 28, 1994).

   ‹bullet› VCAPCD Rule 56, Open Fires (submitted May 24, 1994).

   A more detailed evaluation can be found in EPA's evaluation reports for these rules.

   EPA is publishing this rule without prior proposal because the Agency views this as a noncontroversial amendment and anticipates no adverse comments. However, in the proposed rules section of this Federal Register publication, EPA is publishing a separate document that will serve as the proposal to approve the SIP revision should relevant adverse comments be filed. This rule will be effective July 19, 1999 without further notice unless the Agency receives relevant adverse comments by June 17, 1999.

   If the EPA receives such comments, then EPA will publish a timely withdrawal informing the public that the rule will not take effect. All public comments received will then be addressed in a subsequent final rule based on the proposed rule. The EPA will not institute a second comment period on this rule. Any parties interested in commenting on this rule should do so at this time. If no such comments are received, the public is advised that this rule will be effective on July 19, 1999 and no further action will be taken on the proposed rule.

4. Administrative Requirements

   1. Executive Order 12866

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

   2. Executive Order 12875

      Under Executive Order 12875, Enhancing the Intergovernmental Partnership, EPA may not issue a regulation that is not required by statute and that creates a mandate upon a State, local or tribal government, unless the Federal government provides the funds necessary to pay the direct compliance costs incurred by those governments, or EPA consults with those governments. If EPA complies by consulting, Executive Order 12875 requires EPA to provide to the Office of Management and Budget a description of the extent of EPA's prior consultation with representatives of affected State, local and tribal governments, the nature of their concerns, copies of any written communications from the governments, and a statement supporting the need to issue the regulation. In addition, Executive Order 12875 requires EPA to develop an effective process permitting elected officials and other representatives of State, local and tribal governments ``to provide meaningful and timely input in the development of regulatory proposals containing significant unfunded mandates.'' Today's rule does not create a mandate on State, local or tribal governments. The rule does not impose any enforceable duties on these entities. Accordingly, the requirements of

      [[Page 26879]]

      section 1(a) of E.O. 12875 do not apply to this rule.

   3. Executive Order 13045

      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 E.O. 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 E.O. 13045 because it does not involve decisions intended to mitigate environmental health or safety risks.

   4. Executive Order 13084

      Under Executive Order 13084, Consultation and Coordination with Indian Tribal Governments, EPA may not issue a regulation that is not required by statute, that significantly or uniquely affects the communities of Indian tribal governments, and that imposes substantial direct compliance costs on those communities, unless the Federal government provides the funds necessary to pay the direct compliance costs incurred by the tribal governments, or EPA consults with those governments. If EPA complies by consulting, Executive Order 13084 requires EPA to provide to the Office of Management and Budget, in a separately identified section of the preamble to the rule, a description of the extent of EPA's prior consultation with representatives of affected tribal governments, a summary of the nature of their concerns, and a statement supporting the need to issue the regulation. In addition, Executive Order 13084 requires EPA to develop an effective process permitting elected officials and other representatives of Indian tribal governments ``to provide meaningful and timely input in the development of regulatory policies on matters that significantly or uniquely affect their communities.'' Today's rule does not significantly or uniquely affect the communities of Indian tribal governments. Accordingly, the requirements of section 3(b) of E.O. 13084 do not apply to this rule.

   5. 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 final 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).

   6. Unfunded Mandates

      Under section 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 annual costs to State, local, or tribal governments in the aggregate; or to 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 promulgated does not include a Federal mandate that may result in estimated annual 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.

   7. Submission to Congress and the Comptroller General

      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. This rule is not a ``major'' rule as defined by 5 U.S.C. 804(2).

   8. Petitions for Judicial Review

      Under section 307(b)(1) of the Clean Air Act, petitions for judicial review of this action must be filedin the United States Court of Appeals for the appropriate circuit by July 19, 1999. 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).)
