40 CFR Part 52

[CA 105-153a; FRL-6378-7]


Approval and Promulgation of Implementation Plans; California 
State Implementation Plan Revision; Kern County Air Pollution Control 
District; Mojave Desert Air Quality Management District; Ventura County 
Air Pollution Control District

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

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

SUMMARY: EPA is taking direct final action to approve revisions to the 
California State Implementation Plan (SIP). The revisions concern rules 
from the Kern County Air Pollution Control District (KCAPCD), the 
Mojave Desert Air Quality Management District (MDAQMD), and the Ventura 
County Air Pollution Control District (VCAPCD). The rules control 
oxides of nitrogen (NOX) from cement kilns and electric 
power generating facilities. This approval action will incorporate 
these three rules into the Federally approved SIP. The intended effect 
of approving these rules is to regulate emissions of NOX in 
accordance with the requirements of the Clean Air Act, as amended in 
1990 (CAA or the Act). Thus, EPA is finalizing the approval of these 
revisions 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 nonattainment 
areas.

DATES: These rules are effective on September 20, 1999 without further 
notice, unless EPA receives adverse comments by August 19, 1999. If EPA 
receives such comments, it will publish a timely withdrawal in the 
Federal Register informing the public that this rule will not take 
effect.

SUPPLEMENTARY INFORMATION:

I. Applicability

    The rules being approved into the California SIP include: KCAPCD's 
Rule 425.3, Portland Cement Kilns (Oxide of Nitrogen); MDAQMD's Rule 
1158, Electric Power Generating Facilities; and VCAPCD's Rule 59, 
Electric Power Generating Equipment--Oxides of Nitrogen Emissions. 
These rules were submitted by the California Air Resources Board (CARB) 
to EPA on October 19, 1994 (Rule 425.3) and March 10, 1998 (Rule 1158 
and Rule 59).

II. Background

    On November 15, 1990, the Clean Air Act Amendments of 1990 (CAA or 
the Act) were enacted. Public Law 101-549, 104 Stat. 2399, codified at 
42 U.S.C. 7401-7671q. The air quality planning requirements for the 
reduction of NOX emissions through reasonably available 
control technology (RACT) are set out in section 182(f) of the CAA. On 
November 25, 1992, EPA published a proposed rule entitled ``State 
Implementation Plans; Nitrogen Oxides Supplement to the General 
Preamble; Clean Air Act Amendments of 1990 Implementation of Title I; 
Proposed Rule,'' (the NOX Supplement) which describes the 
requirements of section 182(f). The November 25, 1992, proposed rule 
should be referred to for further information on the NOX 
requirements and is incorporated into this document by reference.
    Section 182(f) of the Clean Air Act requires States to apply the 
same requirements to major stationary sources of NOX 
(``major'' as defined in section 302 and section 182(c), (d), and (e)) 
as are applied to major stationary sources of volatile organic 
compounds (VOCs), in moderate or above ozone nonattainment areas. Kern 
County area is classified as serious; the Southeast Desert Air Basin 
managed by MDAQMD and the Ventura County area are classified as severe; 
1 therefore these areas were subject to the RACT 
requirements of section 182(b)(2), cited below, and the November 15, 
1992 deadline.
---------------------------------------------------------------------------

    \1\ Kern County area, Ventura County area, and Southeast Desert 
Air Basin managed by MDAQMD retained their designations of 
nonattainment and was classified by operation of law pursuant to 
sections 107(d) and 181(a) upon the date of enactment of the CAA. 
See 56 FR 56694 (November 6, 1991).
---------------------------------------------------------------------------

    Section 182(b)(2) requires submittal of RACT rules for major 
stationary sources of VOC emissions (not covered by a pre-enactment 
control techniques guidelines (CTG) document or a post-enactment CTG 
document) by November 15, 1992. There were no NOX CTGs 
issued before enactment and EPA has not issued a CTG document for any 
NOX sources since enactment of the CAA. The RACT rules 
covering NOX sources and submitted as SIP revisions, are 
expected to require final installation of the actual NOX 
controls as expeditiously as practicable, but no later than May 31, 
1995.
    The State of California submitted many RACT rules for incorporation 
into its SIP on October 19, 1994, March 3 and 10, 1998 including the 
rules being acted upon in this document. This document addresses EPA's 
direct-final action for KCAPCD Rule 425.3, Portland Cement Kilns 
(Oxides of Nitrogen); MDAQMD Rule 1158, Electric Power Generating 
Facilities; and VCAPCD Rule 59, Electric Power Generating Equipment--
Oxides of Nitrogen Emissions. KCAPCD adopted Rule 425.3 on October 13, 
1994, MDAQMD adopted Rule 1158 on August 25, 1997, and VCAPCD adopted 
Rule 59 on July 15, 1997. The submitted KCAPCD's Rule 425.3 was found 
to be complete on October 21, 1994; MDAQMD's Rule 1158 and VCAPCD's 
Rule 59 were found to be complete on May 21, 1998 pursuant to EPA's 
completeness criteria that are set forth in 40 CFR part 51, appendix V 
2 and are being finalized for approval into the SIP. By 
today's document, EPA is taking direct final action to approve these 
rules into the Federally approved 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).
---------------------------------------------------------------------------

    NOX emissions contribute to the production of ground 
level ozone and smog. KCAPCD's Rule 425.3 controls emissions of 
NOX from cement kilns; MDAQMD's Rule 1158 and VCAPCD's Rule 
58 control emissions of NOX from electric power generating 
facilities. These rules were adopted as part of KCAPCD's, MDAQMD's, and 
VCAPCD's efforts to achieve the National Ambient Air Quality Standards 
(NAAQS) for ozone and in response to the CAA requirements cited above. 
The following is EPA's evaluation and final action for these rules.

III. EPA Evaluation and Action

    In determining the approvability of a NOX 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). The EPA interpretation of these requirements, 
which forms the basis for this action, appears in various EPA policy 
guidance documents.3 Among these provisions is the 
requirement that a NOX rule must, at a minimum, provide for 
the implementation of RACT for stationary sources of NOX 
emissions.
---------------------------------------------------------------------------

    \3\ Among other things, the pre-amendment guidance consists of 
those portions of the proposed post-1987 ozone and carbon monoxide 
policy that concern RACT, 52 FR 45044 (November 24, 1987); ``Issues 
Relating to VOC Regulation Cutpoints, Deficiencies, and Deviations, 
Clarification to Appendix D of November 24, 1987 Federal Register 
Notice'' (Blue Book) (notice of availability was published in the 
Federal Register on May 25, 1988).
---------------------------------------------------------------------------

    For the purposes of assisting State and local agencies in 
developing NOX RACT rules, EPA prepared the NOX 
Supplement to the General Preamble, cited above (57 FR 55620). In the 
NOX Supplement, EPA provides guidance on how RACT will be 
determined for stationary sources of NOX emissions. While 
most of the guidance issued by EPA on what constitutes RACT for 
stationary sources has been directed towards application for VOC 
sources, much of the guidance is also applicable to RACT for stationary 
sources of NOX (see section 4.5 of the NOX 
Supplement). In addition, pursuant to

[[Page 38834]]

section 183(c), EPA is issuing alternative control technique documents 
(ACTs), that identify alternative controls for categories of stationary 
sources of NOX. The ACT documents will provide information 
on control technology for stationary sources that emit or have the 
potential to emit 25 tons per year or more of NOX. However, 
the ACTs will not establish a presumptive norm for what is considered 
RACT for stationary sources of NOX. In general, the guidance 
documents cited above, as well as other relevant and applicable 
guidance documents, have been set forth to ensure that submitted 
NOX RACT rules meet Federal RACT requirements and are fully 
enforceable and strengthen or maintain the SIP.
    There is currently no version of KCAPCD Rule 425.3, Portland Cement 
Kilns in the SIP. Rule 425.3 controls NOX emissions from 
Portland cement kilns operated within the Kern County area. The 
submitted rule includes the following provisions: applicability, 
exemptions, definitions, emission limits, compliance determination and 
monitoring, recordkeeping, test methods, and compliance schedule.
    EPA developed alternative control technique (ACT) documents for 
categories of stationary sources that either emit or have the potential 
to emit 25 tons per year or more of NOX, to assist states in 
making RACT determinations. However, the ACTs do not establish a 
presumptive norm for what is considered RACT for stationary sources of 
NOX. Cement kilns have been identified as a major stationary 
source that emit more than 25 tons of NOX per year. The ACT 
for cement kilns provides technical information for use by state and 
local agencies to develop and implement regulatory programs to control 
NOX emissions from cement manufacturing operations. The ACT 
reports a range of NOX emission factors from 0.90 to 19.5 
lbs./ton for different cement kiln types and processes.
    Rule 425.3 sets RACT NOX emission limits at 11.6 lbs./
ton of clinker produced averaged on a 24 consecutive hour period and/or 
at 6.4 lbs./ton of clinker produced averaged on a 30 consecutive day 
period. These limits were set based on initial source tests and are 
comparable to other district NOX emission limits for cement 
kilns; they are within the ACT NOX emissions factors (0.90-
19.5 lbs./ton) for cement manufacturing operation.
    When reviewing rules for SIP approvability, EPA evaluates 
enforceability elements such as test methods, recordkeeping, and 
compliance determinations in addition to RACT emission limits. Rule 
425.3 strengthens the SIP with enforceable measures such as 
applicability, definition, emission limits, recordkeeping, test 
methods, and compliance schedule. Therefore, Rule 425.3 meets the 
federal RACT by meeting the above requirements.
    In evaluating the rule, EPA must determine whether the CAA 
requirement that RACT will be implemented by May 31, 1995 is met. The 
rule requires final compliance by May 31, 1995. Kilns that need to 
retrofit are allowed full compliance by May 31, 1997. Rule 425.3 meets 
EPA's RACT guideline and May 31, 1995 implementation requirements by 
requiring RACT be implemented by May 1997 and interim measures 
including submission of a compliance plan, and an application for 
authority to construct, are met to ensure progress toward final 
compliance with the rule.
    There is currently no version of MDAQMD's Rule 1158, Electric Power 
Generating Facilities in the SIP. Rule 1158 controls NOX 
emissions from electric power generating facilities within the 
Southeastern Desert Air Basin managed by MDAQMD. The submitted rule 
includes the following provisions: applicability, emission limits, 
exemptions, monitoring requirements, recordkeeping, averaging time, 
test methods, definitions, and compliance schedule.
    EPA established RACT emission levels for electric utility boilers 
and recommended for other source categories that States/Districts make 
RACT determinations comparable to those EPA established for electric 
utility boilers. This comparability should be based on several factors 
including cost, cost-effectiveness, and emission reductions.
    The CARB RACT/BARCT Guidance 4 document for stationary 
gas turbines suggests the NOX limits of 42 ppm (gas-fired) 
and 65 ppm (liquid-fired) for units rated 0.30 MW and greater. EPA has 
used the NOX Supplement to the General Preamble 
(NOX Supplement) document and the CARB's RACT/BARCT Guidance 
for gas turbines in evaluating Rule 1158 for consistency with the CAA's 
RACT requirements.
---------------------------------------------------------------------------

    \4\ Determination of Reasonably Available Control Technology and 
Best Available Retrofit Control Technology for gas turbines (RACT/
BARCT Guidance for stationary gas turbines), California Air 
Resources Board, May 18, 1992.
---------------------------------------------------------------------------

    The RACT limits for utility boilers range 0.20-0.30 pounds of 
NOX per million Btu (lbs./MMBtu) (167-251 ppm) 
for burning gaseous and liquid fuels. The emission limits in CARB's 
RACT/BARCT determination (42/65 ppm) are generally comparable to those 
specified in the NOX Supplement for electric utility 
boilers.
    Rule 1158's NOX emission limits ((70-125 ppm) gas-fired 
and (115-225 ppm) liquid-fired) for boilers, and (42 ppm (gas-fired) 
and 65 ppm (liquid-fired) for combined-cycle gas turbines are below or 
within the NOX Supplement allowable emission limits (167-251 
ppm) for electric utility boilers and the CARB's RACT/BARCT Guidance 
emission limits (42/65 ppm) for gas turbines. The rule is generally 
consistent with EPA guidelines and CARB's RACT/BARCT Guidance 
requirements. The rule contains enforceability measures such as 
applicability, emission limits, exemptions, monitoring requirements, 
recordkeeping, averaging time, test methods, definitions, and 
compliance schedule. The rule also requires final compliance with the 
emission limits by May 31, 1995. Therefore, Rule 1158 meets the federal 
RACT guidance and the May 31, 1995 implementation deadline by meeting 
the above requirements.
    On January 22, 1997, EPA approved into the SIP a version of Rule 
59, Electric Power Generating Equipment that had been revised by VCAPCD 
on October 12, 1993. Revisions to this rule were subsequently adopted 
on July 15, 1997 and submitted to EPA. VCAPCD's submitted Rule 59, 
Electric Power Generating Equipment--Oxides of Nitrogen Emissions 
includes the following significant changes from the current SIP:
     Rule 59 has been revised so it will apply to any owner/
operator of electric power generating steam boilers within VCAPCD area;
     A threshold heat input capacity greater than 300 million 
British Thermal Unit per hour (MMBtu/hr) has been added;
     The NOX emission limits have been changed to a 
uniform and more stringent limit of 0.10 pounds per megawatt hour 
(lbs./MW-hr);
     The use of continuous emission monitoring (CEM) system to 
determine compliance has been added;
     Compliance period has been changed from the rolling 
twenty-four hours to an hourly average not to exceed twenty-four hours;
     Use of 40 CFR 75.10(d)(1) provisions in lieu of the hourly 
calculation of NOX emission rates;
     Clarification of the 96-hours exemption during fuel oil 
system tests;
     Recordkeeping has been increased from four to five years;
     Deletion of extraneous provisions and obsolete 
requirements in the rule; and

[[Page 38835]]

     Other minor changes of the rule to improve clarity.
    When reviewing rules for SIP approvability, EPA evaluates 
enforceability elements such as test methods, recordkeeping, and 
compliance determinations as well as RACT emission limits. All these 
elements are already in the SIP-approved version of the rule. The 
revised rule is more stringent than the SIP approved version of the 
rule, which was previously determined to meet RACT requirements. EPA 
believes the addition of 300 MMBtu/hr applicability cut-off and the 
changing of the compliance period from a 24-hour averaging to a 
flexible hourly average is not a relaxation restricted under 110(l) of 
the Act because the heat rate ratings of the existing units affected by 
this amendment are much higher than the 300 MMBtu/hr cut-off and the 
hourly averaging is more stringent than the 24-hour average compliance 
period. The additional reduction obtained beyond those attributable to 
RACT are assumed necessary for VCAPCD's attainment planning purposes.
    A more detailed discussion of the sources controlled, the controls 
required, and the justification for why these controls represent RACT 
can be found in the Technical Support Documents (TSDs) for KCAPCD's 
Rule 425.3, MDAQMD's Rule 1158, and VCAPCD's Rule 59 dated June 1, 
1999.
    EPA has evaluated the submitted rules and has determined that they 
are consistent with the CAA, EPA regulations and EPA policy. Therefore, 
KCAPCD's Rule 425.3, Portland Cement Kilns (Oxides of Nitrogen), 
MDAQMD's Rule 1158, Electric Power Generating Facilities, and VCAPCD's 
Rule 59, Electric Power Generating Equipment--Oxides of Nitrogen 
Emissions are being approved under section 110(k)(3) of the CAA as 
meeting the requirements of section 110(a), section 182(b)(2), section 
182(f) and the NOX Supplement to the General Preamble.
    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 
adverse comments be filed. This rule will be effective September 20, 
1999 without further notice unless the Agency receives adverse comments 
by August 19, 1999.
    If the EPA receives such comments, then EPA will publish a timely 
withdrawal in the Federal Register 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 September 20, 1999 and no further action will 
be taken on the proposed rule.

IV. Administrative Requirements

A. 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.

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

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

D. 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.

E. 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

[[Page 38836]]

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).

F. 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.

G. 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).

H. Petitions for Judicial Review

    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 September 20, 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).)
