[CA 009-0137a; FRL-6337-8]

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).

II. 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). 1

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 2 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.

III. 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:

Portland Cement Kilns--0.30 pounds per ton dry feed.

Portland Cement Clinker Coolers--0.10 pounds per ton dry

feed.

Sewage Sludge Incinerators--1.30 pounds per ton dry sludge

input.

Rotary Lime Kilns--0.30 pounds per ton limestone feed.

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:

U.S. Forest Service is deleted as an agency authorized to

issue burn permits.

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:

Restricts the use of orchard heaters to those approved by

the California Air Resources Board.

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:

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.

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:

KCAPCD Rule 409, Fuel Burning Equipment (submitted June

23, 1998).

LCAQMD Section (Rule) 248.5, Prescribed Burning

(Definition) (submitted February 7, 1989).

LCAQMD Section (Rule) 270, Wildland Vegetation Management

Burning (Definition) (submitted February 7, 1989).

LCAQMD Section (Rule) 640, (Permit Exemptions) (submitted

March 10, 1998).

LCAQMD Section (Rule) 1002, (Agencies Authorized to Issue

Permits) (submitted May 18, 1998).

LCAQMD Section (Rule) 1010, (No-Burn Day) (submitted March

26, 1990).

LCAQMD Section (Rule) 1350, Burning of Standing Tule

(submitted March 10, 1998).

MCAPCD Rule 4.11, Orchard Heaters (submitted December 31,

1990).

NSAQMD Rule 211, Process Weight per Hour (submitted

October 28, 1996).

SJVUAPCD Rule 4301, Fuel Burning Equipment (submitted

September 28, 1994).

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.

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

[[Page 26879]]

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 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 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 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).)
