Federal Register / Vol. 61, No. 84 / Tuesday, April 30, 1996 / Rules and Regulations 18959

In a subsequent matter not

contemplated in the proposed

rulemaking, the state has made one

regulatory change concerning when a

source shall apply for a voluntary

operating permit. In the original rule,

the date of March 1, 1995, was

specified. However, due to the delay in

receiving approval of the program, the

state revised its rule at 22.203(1)a(1) to

read that applications are due 90 days

after approval of the state’s Title V

program (October 1, 1995).

This change became effective on

February 24, 1995, and was submitted to

the EPA under the Director’s signature

on February 27, 1996. This change is

approvable by the EPA because it is

noncontroversial and it precludes

sources from the tenuous position of

applying for a program not yet approved

(which the original rule did not

anticipate).

EPA Action

The EPA is taking final action to

approve revisions submitted on

December 8, 1994; February 16, 1996;

and February 27, 1996, for the state of

Iowa. This action makes the state’s

program a federally enforceable part of

the SIP, and also makes such permits

federally enforceable for hazardous air

pollutants by means of EPA’s approval

under section 112(l).

Nothing in this action should be

construed as permitting or allowing or

establishing a precedent for any future

request for revision to any SIP. Each

request for revision to the SIP shall be

considered separately in light of specific

technical, economic, and environmental

factors, and in relation to relevant

statutory and regulatory requirements.

SIP approvals under section 110 and

subchapter I, Part D of the Clean Air Act

(CAA) do not create any new

requirements, but simply approve

requirements that the state is already

imposing. Therefore, because the federal

SIP approval does not impose any new

requirements, the EPA certifies that it

does not have a significant impact on

any small entities affected. Moreover,

due to the nature of the federal-state

relationship under the CAA, preparation

of a regulatory flexibility analysis would

constitute federal inquiry into the

economic reasonableness of state action.

The CAA forbids the EPA to base its

actions concerning SIPs on such

grounds (Union Electric Co. v. U.S.

E.P.A., 427 U.S. 246, 256–66 (S.Ct.

1976); 42 U.S.C. 7410(a)(2)).

This action has been classified as a

Table 3 action for signature by the

Regional Administrator under the

procedures published in the Federal

Register on January 19, 1989 (54 2214–

2225), as revised by a July 10, 1995,

memorandum from Mary Nichols,

Assistant Administrator for Air and

Radiation. The Office of Management

and Budget has exempted this

regulatory action from E.O. 12866

review.

Unfunded Mandates

Under sections 202, 203, and 205 of

the Unfunded Mandates Reform Act of

1995 (‘‘Unfunded Mandates Act’’),

signed into law on March 22, 1995, the

EPA must undertake various actions in

association with proposed or final rules

that include a federal mandate that may

result in estimated costs of $100 million

or more to the private sector, or to state,

local, or tribal governments in the

aggregate.

Through submission of this SIP, the

state has elected to adopt the program

provided for under section 110 of the

CAA. These rules may bind state and

local governments to perform certain

actions and also require the private

sector to perform certain duties. To the

extent that the rules being finalized for

approval by this action will impose new

requirements, sources are already

subject to these regulations under state

law. Accordingly, no additional costs to

state or local governments, or to the

private sector, result from this final

action. The EPA has also determined

that this final action does not include a

mandate that may result in estimated

costs of $100 million or more to state or

local governments in the aggregate or to

the private sector. The EPA has

determined that these rules result in no

additional costs to tribal government.

Under section 307(b)(1) of the CAA,

petitions for judicial review of this

action must be filed in the United States

Court of Appeals for the appropriate

circuit by July 1, 1996. 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).)

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

Ventura County Air Pollution Control

District (VCAPCD), the Sacramento

Metropolitan Air Quality Management

Division (SMAQMD), and the Placer

County Air Pollution Control District

(PCAPCD). This approval action will

incorporate three rules into the federally

approved SIP. The intended effect of

approving these rules is to regulate

emissions of oxides of nitrogen (NOX) in

accordance with the requirements of the

Clean Air Act, as amended in 1990

(CAA or the Act). The rules control NOX

emissions from natural gas-fired central

furnaces, stationary internal combustion

engines, and biomass boilers.

DATES: This action is effective on July 1,

1996, unless adverse or critical

comments are received by May 30, 1996.

If the effective date is delayed, a timely

notice will be published in the Federal

Register.

Applicability

This notice addresses EPA’s direct

final action for the following rules:

• VCAPCD, Rule 74.22, Natural GasFired, Central Fan- Type Furnaces;

• SMAQMD, Rule 412, Stationary

Internal Combustion Engines Located at

Major Stationary Sources; and

• PCAPCD, Rule 233, Biomass

Boilers.

The rules were adopted by the

districts, submitted by the State of

California, and found complete

pursuant to EPA’s completeness criteria

set forth in 40 CFR Part 51 Appendix V 1

on the following dates:

• Rule 74.22—November 9, 1993;

February 11, 1994; April 11, 1994.

• Rule 412—June 1, 1995; June 23,

1995; June 30, 1995.

• Rule 233—October 6, 1994; October

19, 1994; October 21, 1995.

Background:

On November 15, 1990, the Clean Air

Act Amendments of 1990 (CAA) were

enacted. Pub. L. 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 notice of

proposed rulemaking 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 NOX Supplement 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. The Sacramento Metropolitan

Area (including part of Placer County)

and the Ventura County Area are

classified as a severe nonattainment

areas for ozone.2. Both areas are subject

to the RACT requirements of section

182(b)(2), cited above.

Section 182(b)(2) requires submittal of

RACT rules for major stationary sources

of VOC emissions (not covered by a preenactment control technique 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 category

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 by May 31, 1995 for those

sources where installation by that date

is practicable.

NOX emissions contribute to the

production of ground level ozone and

smog. The three rules control emissions

of NOX from various industries used in

a wide variety of applications. The rules

were adopted as part of the VCAPCD’s,

SMAQMD’s, and PCAPCD’s efforts to

achieve and maintain the National

Ambient Air Quality Standards

(NAAQS) for ozone. All three rules are

required to satisfy the mandates of the

Clean Air Act requirements, and were

submitted pursuant to the CAA

requirements cited above.

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

interpretations of these requirements,

which form the basis for this action,

appear in the NOX Supplement and

various other 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.

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 should be determined for

major stationary sources of NOX

emissions. The document sets RACT

emission levels specifically for electric

utility boilers. For all other source

Commercial Boilers, Steam Generators, and Process

Heaters (RACT/BARCT guidance for ICI boilers),

California Air Resources Board, July 18, 1991.

categories, EPA expects States/Districts

to establish RACT levels comparable to

those levels for utility boilers taking into

account cost, cost-effectiveness, and

emission reductions.

While most of the guidance issued by

EPA (previous to the NOX Supplement)

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 section 183(c),

EPA has issued alternative control

techniques documents (ACTs), that

identify alternative controls for most

categories of stationary sources of NOX.

The ACT documents provide

information on control technology for

stationary sources that emit or have the

potential to emit 25 tons per year or

more of NOX. While providing guidance

and information for States to use in

making RACT determinations, the ACTs

do 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 issued by EPA to

ensure that submitted NOX RACT rules

are fully enforceable and strengthen or

maintain the SIP.

Placer Rule 233 sets NOX limits at 115

parts per million (ppm) corrected to

12% carbon dioxide (0.2096 pounds per

million British Thermal Units (lb/

MMBTU)). This limit corresponds to

162 ppm corrected to 3% oxygen. The

district believes this limit meets RACT

because it is similar to the RACT limits

that EPA has set for electric utility

boilers (0.20–0.50 lb/MMBTU). The

district set the limits based on current

emission limitations at existing facilities

in Placer county, and is not expecting to

achieve any further emissions

reductions as a result of adopting this

rule. Additionally, there will be no

additional costs incurred by the sources

subject to this rule as a result of its

adoption.

The California Air Resources Board

RACT/BARCT Guidance 4 document for

institutional, commercial, and industrial

boilers suggests a RACT limit of 70 ppm

corrected to 3% O2 for such units fired

with gaseous fuel and 115–150 ppm for

units fired with fuels other than gas.

EPA established RACT 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, costeffectiveness, and emission reductions.

Because of the variability in application,

equipment, and input and output

characteristics of different NOX source

categories, comparability cannot easily

be done solely by comparing the

emissions rates. That is why EPA

suggests that RACT levels should be

made in comparison to the limits set for

electric utility boilers using the factors

cited above.

EPA does not necessarily agree that

the limits in Rule 233 represent what

would generally be considered RACT

for this source category, even though the

emissions rates are similar to those set

for utility boilers. However, EPA

recognizes that the two sources covered

by this rule are already applying NOX

reduction technology according to their

permits (district and federal). One

source is permitted at 54 ppm at 12%

CO2 and the other at 115 ppm at 12%

CO2. Because these sources are currently

utilizing NOX controls, EPA believes the

cost of achieving additional small

reductions of NOX to meet the general

RACT limits would be cost prohibitive.

In addition, PCAPCD is not claiming

any emissions reductions in their

Federal ozone attainment plan for Rule

233 and has submitted the rule for

incorporation into the SIP to prevent

any NOX emissions increases from this

source category. Therefore, EPA agrees

that in this circumstance the limits set

in Rule 233 for these sources satisfies

the RACT requirements of the CAA.

Ventura Rule 74.22 sets NOX emission

levels at 40 nanograms per joule of heat

output (ng/J). This limit represents a

75% average reduction from typical

natural-gas fired furnaces and will be

achieved from new units being

purchased and installed. The limit was

chosen so as not to require homeowners

or businesses to modify furnace

enclosures when replacing existing

furnaces in order to keep the costs

appropriate. The VCAPCD estimates the

cost of compliance at approximately

$2.24 per pound of NOX reduced, and

expects the rule to achieve reductions of

1.5 tons per day. Final compliance is

required by May 31, 1994.

Sacramento Rule 412 sets limits for

RACT and BARCT in the rule. The

RACT levels are set at 50/125/700 ppm

for rich burn, lean burn, and diesel

engines, respectively. The BARCT limits

are set at 25/65/80 ppm for rich, lean,

and diesel engines, respectively. The

rule is structured to allow exemptions

from compliance with the emissions

limits for some units which operate at

annual levels that the control of which

would not be cost-effective. The rule is

expected to achieve reductions of 2.2

tons per year. RACT is required to be

implemented by July 1, 1995.

EPA is incorporating these rules into

the SIP because they strengthen the SIP

through the addition of enforceable

measures such as NOX emission limits,

recordkeeping, test methods,

definitions, and compliance tests. EPA

believes all three rules for these source

categories in each district satisfy the

RACT requirements of the CAA. A more

detailed discussion of the sources

controlled, the controls required, and

the analysis of how these controls meet

RACT can be found in the Technical

Support Document (TSD) and its

attachments, dated November 1995.

EPA has evaluated the submitted

rules and has determined that they are

consistent with the CAA, EPA

regulations and EPA policy. All three

rules are new rules establishing RACT

for their particular category, and contain

implementation dates consistent with

the CAA and EPA’s policy. Therefore,

all three are being approved under

section 110(k)(3) of the CAA as meeting

the requirements of section 110(a) and

Part D.

Nothing in this action should be

construed as permitting or allowing or

establishing a precedent for any future

implementation plan. Each request for

revision to the state implementation

plan shall be considered separately in

light of specific technical, economic,

and environmental factors and in

relation to relevant statutory and

regulatory requirements.

EPA is publishing this document

without prior proposal because the

Agency views this as a noncontroversial

amendment and anticipates no adverse

comments. However, in a separate

document in this Federal Register

publication, the EPA is proposing to

approve the SIP revision should adverse

or critical comments be filed. This

action will be effective July 1, 1996,

unless, by May 30, 1996, adverse or

critical comments are received.

If the EPA receives such comments,

this action will be withdrawn before the

effective date by publishing a

subsequent document that will

withdraw the final action. All public

comments received will then be

addressed in a subsequent final rule

based on this action serving as a

proposed rule. The EPA will not

institute a second comment period on

this action. Any parties interested in

commenting on this action should do so

at this time. If no such comments are
18962 Federal Register / Vol. 61, No. 84 / Tuesday, April 30, 1996 / Rules and Regulations

received, the public is advised that this

action will be effective July 1, 1996.

Regulatory Process

Under the Regulatory Flexibility Act,

5 U.S.C. 600 et. seq., EPA must prepare

a regulatory flexibility analysis

assessing the impact of any proposed or

final rule on small entities. 5 U.S.C. 603

and 604. Alternatively, EPA may certify

that the rule will not have a significant

impact on a substantial number of small

entities. Small entities include small

businesses, small not-for-profit

enterprises and government entities

with jurisdiction over population of less

than 50,000.

SIP approvals under sections 110 and

301(a) and subchapter I, Part D of the

CAA do not create any new

requirements, but simply approve

requirements that the State is already

imposing. Therefore, because the

Federal SIP-approval does not impose

any new requirements, I certify that it

does not have a significant impact on

any small entities affected. Moreover,

due to the nature of the Federal-state

relationship under the CAA, preparation

of a regulatory flexibility analysis would

constitute Federal inquiry into the

economic reasonableness of state action.

The CAA forbids EPA to base its actions

concerning SIPs on such grounds.

Unfunded Mandates

Under Sections 202, 203, and 205 of

the Unfunded Mandates Reform Act of

1995 (‘‘Unfunded Mandates Act’’),

signed into law on March 22, 1995, EPA

must undertake various actions in

association with proposed or final rules

that include a Federal mandate that may

result in estimated costs of $100 million

or more to the private sector or to State,

local, or tribal governments in the

aggregate.

Through submission of this state

implementation plan or plan revision,

the State and any affected local or tribal

governments have elected to adopt the

program provided for under Part D of

the Clean Air Act. These rules may bind

State, local, and tribal governments to

perform certain actions and also require

the private sector to perform certain

duties. The rules being approved by this

action will impose no new requirements

because affected sources are already

subject to these regulations under State

law. Therefore, no additional costs to

State, local, or tribal governments or to

the private sector result from this action.

EPA has also determined that this final

action does not include a mandate that

may result in estimated costs of $100

million or more to State, local, or tribal

governments in the aggregate or to the

private sector.

This action has been classified as a
