SUPPLEMENTARY INFORMATION:

I. Background

The Columbia Falls, Montana area

.was designated nonattainment for PMo

and classified as moderate under

sections 107(d)(4)(B) and 188(a) of the

Clean Air Act, upon enactment of the

Clean Air Act Amendments of 1990.'

See 56 FR 56694 (November 6, 1991); 40

CFR 81.327 (Flathead County; Columbia

Falls and vicinity). The air quality

planning requirements for moderate

PMo nonattajnment areas are set out in

subparts I and 4 of part D, title I of the

Act.

The EPA has issued a "General

Preamble" describing EPA's preliminary

views on how EPA intends to review

SIPs and SIP revisions submitted under

title I of the Act.,including those State

submittals containing moderate PMIo

nonattainment area SIP requirements

(see generally 57 FR 13498 (April 16,

1992) and 57 FR 18070 (April 28,

1992)). Because EPA is describing its

interpretations here only in broad terms,

the reader should refer to the General

Preamble for a more detailed discussion

of the interpretations of title I advanced

in this final action and the supporting

rationale.

Those States containing initial

moderate PMo nonattainment areas

were required to submit, among other

things, the following provisions by

November 15, 1991:

1. Provisions to assure that reasonably

available control measures (RACM)

'The 1990 Amendments to the Clean Air Act

made significant changes to the air quality planning

requirements for areas that do not meet (or that

significantly contribute to ambient air quality in a nearby area that does not meet) the PMmo National

Ambient Air Quality Standards (see Public Law No.

101-549, 104 Stat. 2399). References herein are to

the Clean Air Act, as amended ("the Act"), 42

U.S.C. 7401, et seq.

HeinOnline -- 59 Fed. Reg. 17700 1994
Federal Register / Vol. 59, No. 72 / Thursday, April 14, 1994 / Rules and Regulations 17701

(including such reductions in emissions

from existing sources in the area as may be obtained through the adoption, at a

minimum, of reasonably available

control technology (RACT)) shall be

implemented no later than December

10,1993;

2. Either a demonstration (including

air quality modelling) that the plan will

provide for attainment as expeditiously

as practicable but no later than

December 31,1994, or a demonstration

that attainment by that date is

impracticable;

3. Quantitative milestones which are

to be achieved every 3 years and which

demonstrate reasonable further progress (RFP) toward attainment by December

31, 1994;and

4. Provisions to assure that the control

requirements applicable to major stationary sources of PMmo also apply to

major stationary sources of PMmo

precursors except where the

Administrator determines that such

sources do not contribute significantly

to PM,0 levels which exceed the

NAAQS in the area. See sections 172(c),

188, and 189 of the Act.

Some provisions are due at a later

date. States with initial moderate PM1O

nonattainment areas were required to

submit a permit program for the

construction and operation of new and

modified major stationary sources of

PM,0 by June 30, 1992 (see section

189(a)). Such States also were required

to submit contingency measures by

November 15, 1993 that become

effective without further action by the

State or EPA, upon a determination by EPA that the area has failed to achieve

RFP or to attain the PMo NAAQS by the

applicable statutory deadline. See

section 172(c)(9) and 57 FR 13543-

13544.

On January 27, 1994, EPA announced

its proposed approval of the Columbia

Falls, Montana moderate nonattainment

area PMIO SP as meeting those

moderate PMo SIP requirements due on

November 15, 1991 (59 FR 3804-3808).

In that proposed rulemaking action and

related Technical Support Document

(TSD), EPA described in detail its

interpretations of title I and its rationale

for proposing to approve the Columbia

Falls moderate nonattainment area PMo

SIP taking into consideration the

specific factual issues presented. EPA requested public comments on

all aspects of the proposal (please reference 59 FR 3808), and no

comments were received during the

comment period, which ended on

February 28, 1994. This final action on

the Columbia Falls moderate

nonattainment area PMo SIP is

unchanged from the January 27, 1994

proposed approval action.

The discussion herein provides only a

broad overview of the proposed action

EPA is now finalizing. The public is

referred to the January 27, 1994

proposed rule for a more in depth

discussion of the action now being finalized.

U. Response to Comments

EPA did not receive any public

comments regarding its January 27, 1994

proposed approval of the Columbia

Falls moderate nonattainment area PM1O

SIP (59 FR 3804-3808).

This Action

Section 110(k) of the Act sets out

provisions governing EPA's review of

SIP submittals (see 57 FR 13565-13566).

The Columbia Falls SIP consists of two

submittals. The first contains the

Flathead County Air Pollution Control

Program and Air Pollution Plan

regulations. Flathead County contains

two PM,0 nonattainment areas for which

SIPs were due in November 1991:

Columbia Falls and Kalispell. The

Flathead County regulations apply to

both areas and were submitted with the

attainment demonstration for Kalispell

on November 25, 1991, after being approved by the Montana Board of

Health and Environmental Sciences

(MBHES) on November 15, 1991. The

Columbia Falls SIP and attainment

demonstration were not submitted at

that time since a permit necessary to the

control strategy for the SIP was not

finalized. The MBHES issued that

permit and approved the SIP on January 24, 1992. This second submittal to EPA

was made by the Governor on May 6, 1992. Final technical corrections to the

SIP were received by EPA on June 15, 1993. The submittals were intended to

satisfy those moderate PM,o SIP

requirements due for Columbia Falls on

November 15, 1991.

As described in EPA's proposed action on this SIP (59 FR 3804-3808,

January 27, 1994), the Columbia Falls

moderate nonattainment area PM~o plan includes, among other things, a

comprehensive and accurate emissions

inventory, control measures that satisfy the RACM requirement, a demonstration

(including air quality modelling) that

attainment of the PM,o NAAQS will be

achieved by January 1. 1995 2,

provisions for meeting the November

2 The Clean Air Act calls for attainment by

December 31, 1994. Section 188(c)(1). EPA

interprets the State's demonstration as providing for

attainment of the PMo NAAQS by January 1, 1995.

EPA is approving the State's demonstration on the

basis of the de minimis differential between the two dates.

15. 1994 quantitative milestone and

reasonable further progress, and

enforceability documentation. Further,

EPA proposed to determine that major

sources of precursors of PMo do not

contribute significantly to PM,0 levels in excess of the NAAQS in Columbia

Falls 3 Please refer to EPA's notice of

proposed rulemaking (59 FR 3805) and

the TSD for that action for a more detailed discussion of these elements of

the Columbia Falls plan.

In this final rule, EPA is announcing

its approval of those elements of the

Columbia Falls moderate nonattainment area PMo SIP that were due on November 15, 1991, and submitted by

the Governor on November 25, 1991 and'

May 6, 1992, with technical-corrections

submitted in a letter dated June 15,

1993. Specifically, EPA is approving the

Flathead County rules (with the

exception of rules 501 through 506

which are specific to the city of

Kalispell-EPA willitake separate action on the Kalispell PMo nonattainment

area control plan) and the Columbia

Falls PMIO nonattainment area control

plan.

EPA finds that the State of Montana's

PM,0 SIP for the Columbia Falls

moderate nonattainment area meets the

Reasonably Available Control Measures

(RACM), including Reasonably

Available Control Technology (RACT),

requirement. Five sources/source

categories were identified as contributing to the PMo nonattainment

problem in Columbia Falls and,

therefore, were targeted for control in

the SIP. The State has demonstrated that

by applying control measures to area

sources (re-entrained road dust,

residential wood combustion,

prescribed burning, and motor vehicle

exhaust), as well as reducing allowable

emissions through air quality permit

modifications for the Plum Creek

sawmill and fiberboard plant, Columbia

Falls will be in attainment by January 1,

1995 (see footnote # 2) and it does not

appear that applying further control

measures to these sources would

expedite attainment.

EPA views the following measures as reasonable, enforceable, and responsible

for significant PM,0 emissions

reductions in Columbia Falls: (1)

Flathead County Rules No. qO-606,

which provide re-entrained road dust

controls, including sanding and chip

3 The consequences of this finding are to exclude

these sources from the applicability of PM,o nonattainment area control requirements. Note that

EPA's finding is based on the current character of

the area including for example, the existing mix of sources in the area. It is possible, therefore, that

future growth could change the significance of

precursors in the area.

RACT) provisions in the SIP are

described further in the technical

support document associated with

EPA's January 27, 1994 notice of

proposed rulemaking on this SIP.

Further, although no credit was

claimed in the SIP, EPA notes that the

State has adopted, as part of the

Columbia Falls SIP, lie Montana Smoke

Management Plan, which sets standards

for the regulation of prescribed burning.

EPA approved this plan in a separate

rulemaking action. (59 FR 2988, January

20, 1994).

A more detailed discussion of the

individual source contributions, their

associated control measures (including

available control technology) and an

explanation of why certain available

control measures were not

implemented, can be found in the TSD

accompanying EPA's proposed approval

of the Columbia Falls moderate PMo

nonattainment area SIP (59 FR 3804).

EPA has reviewed the State's

documentation and concluded that it

adequately justifies the control

measures-to be implemented. The

implementation of Montana's PMo

nonattainment plan for Columbia Falls

will result in the attainment of the PMo

NAAQS by January 1, 1995 (see footnote

# 2). By this action EPA is approving the

Columbia Falls PMo plan's control

measures as satisfying the RACM,

including RACT, requirement.

As noted, EPA did not propose to

approve some aspects of the Columbia

Falls SIP, as explained in the notice of

,proposed rulemaking (59 FR 3804-3808)

and associated TSD. To address

deficiencies identified by EPA, the State

adopted commitments after public

hearings on November 15, 1991 and

January 24, 1992, and submitted the

commitments to EPA with the

Governor's May 6, 1992 letter, as

additional tasks to be completed to

correct the deficiencies in the Columbia

Falls and statewide SIP. The State has

fulfilled commitments related to SIP,

requirements due November 15, 1991

for the Columbia Falls nonattainment

area. Those items related to deficiencies

in the statewide SIP will be addressed

in a separate action. EPA has

determined that the Columbia Falls SIP

can be fully approved without the State

fulfilling the remaining commitments.

Therefore, EPA is tracking the State's

efforts to meet these commitments, but

approval of the SIP for the Columbia

Falls nonattainment area is not

contingent upon the State meeting them

by the specified dates. Therefore, EPA.

will take separate action, as appropriate,

when the remaining commitments are

fulfilled by the State. A more detailed

discussion of the State's commitments

can be found in EPA's January 27, 1994

proposed approval of the Columbia

Falls moderate nonattainment area PMo

SIP (59 FR 3804-3808) and the TSD for

that action.

The State has made a separate

commitment to testing and further'

dispersion modeling of emissions from

the Columbia Falls Aluminum Company

(CFAC) facility. This facility is located

outside the nonattainment area and

emissions from CFAC were not

identified on the Chemical Mass

Balance analysis of filters collected from

the monitor in the Columbia Falls

nonattainment area. Emissions from

CFAC are a potential concern, however,

since this source accounts for 20 percent

of the emission inventory (at permitted

allowable emissions). EPA will continue

to monitor the testing and assist the

State with any action required by the

results.

Final Action

This document announces EPA's final

action on the rulemaking proposed at 59

FR 3804. As noted elsewhere in this

action, EPA received no adverse public

comments on the proposed action. As a

direct result, the Regional Administrator

has reclassified this action from Table 2

to Table 3 under the processing

procedures established at 54 FR 2214,

January 19, 1989.

Nothing in this action should be

construed as permitting or allowing or

establishing a precedent for any future

request for a revision to any SIP. Each

request for a 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.

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

economic impact on a substantial

number of small entities. Small entities

include small businesses, small not-forprofit enterprises, and government

entities with jurisdiction over .populations of less than 50,000.

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 impose any new requirements, I

certify that it does not have a significant

impact on a substantial number of small

entities affected. Moreover, due to the

nature of the Federal-state relationship

under the Clean Air Act, preparation of

a regulatory 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.

E.P.A., 427 U.S. 246, 256-66 (1976); 42

U.S.C. 7410(a)(2).

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 June 13, 1994.

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 file, 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)).

Executive Order (EO) 12866

This action has been classified as a

Table 3 action by the Regional

Administrator under the procedures

published in the Federal Register on

January 19, 1989 (54 FR 2214-2225), as

ACTION: Final rule.

SUMMARY: The USEPA is approving

revisions to Minnesota's State

Implementation Plan (SIP) for sulfur

dioxide (SO 2) for the Air Quality

Control Region (AQCR) 131 area (excluding the Pine Bend area of Dakota

County and the St. Paul Park/Ashland

area), which were submitted to USEPA on May 29, 1992. These SIP revisions

were submitted by the State of

Minnesota as a means of demonstrating

attainment of the National Ambient Air

Quality Standards (NAAQS) for SO 2. The USEPA proposed to disapprove the

originally submitted SIP revisions on September 13, 1993. However, that

notice of proposed rulemaking stated

that if the issues identified within were satisfactorily addressed by the State by

the end of the 30-day comment period,

and if no other significant adverse

comments were received, USEPA would

proceed with a final approval. The

issues were adequately addressed by the

State and submitted to the USEPA on July 12, 1993. No comments were received on the September 13, 1993,

proposed action. Consequently, the

USEPA is fully approving the SO 2 SIP

revisions for AQCR 131.

EFFECTIVE DATE: This final rule becomes

effective on May16, 1994.

SUPPLEMENTARY INFORMATION:

I. Background

On May 29, 1992, the Minnesota

Pollution Control Agency (MPCA)

submitted to the United States

Environmental Protection Agency

(USEPA), revisions to the State

Implementation Plan (SIP) for sulfur

dioxide (SO 2) in Air Quality Control

Region (AQCR) 131. The seven-county

metropolitan area (AQCR 131) has been'

designated, by the USEPA, as nonattainment for SO2. This submittal was intended to demonstrate attainment

of the National Ambient Air Quality

Standards (NAAQS) for SO2in AQCR

131, excluding an area surrounding the

S0 2 emission sources at Ashland

Petroleum Company, and an area surrounding the SO2 emission sources at

and near Koch Refining Company,

located in Dakota County. These two sources and the surrounding areas were subject to separate submittals and are addressed in separate rulemakings.

On September 13, 1993, a document was published in the Federal Register

(58 FR 47840) which proposed

disapproval of the SO2 SIP revision for

AQCR 131. The proposed notice

discussed the State submittal, including

administrative order, USEPA comments

regarding the administrative orders,

comparison of submittal with sections

110 and 172 requirements, and

proposed rulemaking action. The

disapproval was based on the issues

which had been identified in the notice

by the USEPA. However, the action also

stated that if the issues were

satisfactorily addressed by the end of

the 30-day comment period, and if no adverse comments were received, the

USEPA would proceed with a final

approval. This final rule will present a brief summary of the State submittal,

detail how the USEPA identified issues were addressed, and present our

recommendation for final approval.
