forth, on a State-by-State, pollutant-bypollutant basis (as appropriate), the

attainment status of the abovementioned NAAQS as submitted by the

appropriate States, and approved or as

designated and classified by the EPA.

Designations and classifications revised

as a result of technical corrections will

be republished.

EFFECTIVE DATE: This regulation will

become effective on January 6, 1992.

I. Background

A. Purpose

The purpose of this document is to

announce and promulgate designations,

classifications, and boundaries for areas

of the country with respect to the

NAAQS for ozone, CO, particulate

matter with an aerodynamic diameter

less than or equal to a nominal 10

micrometers (PM-10), and lead in

accordance with the requirements of the

Clean Air Act (CAA).

B. Preeanctment Status and Clean Air

Act Amendments (CAAA) of 1990

The nation's first Federal efforts at

controlling air pollution began in 1963

with passage of the CAA. Four

amendments followed in 1967, 1970, 1977

and 1990. The 1967 Amendments

directed the previous Department of

Health, Education and Welfare to

identify regional areas with common air

masses throughout the nation [Air

Quality Control Regions (AQCR's)]. By

1970, 57 AQCR's were named. Later that

year, 34 additional areas were

announced.

The 1970 Amendments authorized the

Administrator of the newly created EPA

to identify additional areas, but only at

the States' initiative. As of January 1972,

247 AQCR's were listed.

Section 107(d) of the 1977

Amendments gave the EPA the authority

to designate areas nonattainment

without a State's request. After EPA's

initial designation of areas as

attainment/unclassifiable or

nonattainment in 1978, however,

subsequent designations could be made

only at a State's request. In that same

year, EPA published, for the first time, a

list of all section 107(d) nonattainment

areas in 40 CFR part 81.

C. CAAA and Subsequent EPA Actions

This section summarizes the relevant

provisions of the CAAA as applicable to

ozone and CO areas. A discussion of the

provisions applicable to PM-10, SO2,

and lead areas is found in sections II. B.,

C., and D. of this document.

The CAAA of 1990 authorized EPA to

designate areas nonattainment and to

classify them according to degree of

severity. Classification, in turn, triggers

a set of control requirements designed to

bring areas into attainment by their

specified attainment dates.

Under the CAAA of 1990,

preenactment ozone and CO

nonattainment areas were classified on

the date of enactment according to the

severity of their problem. States were

required, by 120 days after enactment, to

submit lists designating all areas of the

State as attainment, unclassifiable, or

nonattainment for ozone and CO. The

EPA was required to promulgate these

lists by 240 days after enactment,

making revisions, including boundary

modifications, as appropriate. Ozone or

CO areas classified serious or higher are

subject to a separate process for

determining boundaries which places a

strong presumption in favor of

expanding boundaries to the

Metropolitan Statistical Area (MSA) [or

Consolidated Metropolitan Statistical

Area (C/MSA)].

D. Chronology of EPA and State Actions

1. CAAA of 1990. The CAAA of 1990

reaffirm the major role of the States in

developing and implementing State

implementation plans (SIP's) to attain

the NAAQS. On November 15, 1990, the

day the CAAA were signed into law,

EPA Administrator William K. Reilly

sent a letter to State Governors alerting

them to the significance of the

legislation and summarizing the

Amendments.

One month later, William G.

Rosenberg, Assistant Administrator for

Air and Radiation, followed up the

November 15, 1990 letter with a second

letter to State Governors. This letter

notified Governors of those initial State

actions or submittals rcquired of States,

particularly those actions needed within

a very short time period.

In January 1991, a thied letter to States

went out from each Regional

Administrator providing more detailed

information on determining

designations, classifications, and

boundaries; notification of SIP

deficiencies; and information about

other early State actions. Attached to

the letter was a list of current and

planned guidance materials that would

be provided by EPA to support State

activities.

2. Chronology of events. The first

official actions the States took came 45

days after enactment of the CAAA

(December 30, 1990). Preenactment

ozone and/or CO nonattainment areas

classified under section 107(d)(4)(A)(iv)

as serious, severe, or extreme would

take as their nonattainment area

boundaries the boundary of their

respective C/MSA unless the State

notified the Administrator, no latei than

45 days after enactment, of its intent to

study the boundaries further (the 45-day

letter].

In addition, under sections 181(a)(4)

and 186(a)(3), EPA was authorized to

reclassify an area upward or downward

(a "bump down") if the design value of

an area placed it within 5 percent of the

next classification. The EPA requested

that States seeking a bump down make

the request within 45 days of enactment.

(Section 181(b)(3) provides that EPA

shall automatically grant the request of

any State to reclassify an ozone

nonattainment area to a higher

classification.)

The next major event occurred 90

days after enactment, February 13, 1991,

when the EPA responded to States'

bump down requests.

On March 15, 1991 (120 days after

enactment), States were required to

submit to EPA a list of all their ozone

and CO nonattainment areas, including

boundary recommendations. States

were urged to submit at the same time

SO2. PM-IO, and lead nonattainment

areas, including boundary

recommendations. States were

encouraged to provide at this time the

additional boundary studies and

recommendations for the serious,

severe, and extreme ozone and CO

areas covered by the 45-day letters. By

56695
569 Fedra Reite/olI6 No 5Wensdy Noebr6"91Rle n euain

May 14, 1991 (180 days after enactment),

EPA Regional Administrators notified

States of any potential modifications to

the States' recommendations. States

were encouraged in the 180-day letter to

respond to EPA's proposal within 20

days (by June 3, 1991, which is 200 days

after enactment) for ozone and CO

areas, and within 60 or 120 days,

depending on the type of modification,

for lead. Many States did so. With respect to ozone and CO,

today's action is final except for the

following counties for ozone: Orange

and Putnam (New York, New JerseyLong Island CMSA); Muskegon

(Muskegon, MI); Washington

(Parkersburg-Marietta, OH) and Pasco

(Tampa, FL); and the following counties

for CO: Hancock, Brooke, and Jefferson

(Steubenville); and Utah (Provo, UT).

With respect to lead, PM-10, and SO2,

refer to the appropriate section below

for a description of the specific action

being taken.

3. Presentation of technical

information. Copies of all of the above

mentioned correspondence and other

correspondence between the States,

interested parties, and EPA regarding

this process are available for review in

the Air Docket No A-90-42 maintained in

Rm. M-1500, 401 M St., SW.,

Washington, DC 20460 (first floor of the

EPA Washington DC, Waterside Mall

Office). Identical information is also

available for review at the EPA Regional

Offices listed above in the addresses

section of this rulemaking package.

Detailed discussions concerning the

basis for EPA's actions and decisions are excluded from this rulemaking and

are included in a Technical Support

Document (TSD). The TSD is also

available in the Air Docket and

respective Regional Offices. Where

appropriate in this rule, the reader is

directed to the TSD for additional

information.

II. Summary of Today's Action

A. Ozone/CO

1. Introduction. This section will

describe EPA's interpretation of the

designations/classifications/boundaries

requirements applicable to ozone/CO

areas; and it will describe EPA's actions

in promulgating or announcing these

decisions.

This section is organized

chronologically. The reader is invited to

refer to the chronology of CAAA

requirements and EPA/State

administrative actions described above.

The most important submissions by the

States, and preliminary and final EPA

actions, are summarized in tables

included as part of this rule.

2. Enactment-a. Designations/

boundaries/classifications-i.

Designations. As described in this

section, at the date of enactment, all

areas of the country were designated

with respect to ozone and CO by

operation of law in accordance with the

preenactment designations. For areas

that were designated nonattainment

before enactment, EPA interprets the

CAAA to maintain the preenactment

designation for the area and to begin a

process for determining the boundaries

for the area.

Section 107(d)(1)(C) provides that

each ozone and CO area designated

nonattainment, attainment, or

unclassifiable immediately before the

date of enactment of the CAAA "is

designated, by operation of law," as a

nonattainment, attainment, or

unclassifiable area, respectively. -

Section 107(d)(2)(A) requires EPA to

publish a Federal Register notice with

respect to this designation, but does not

specify a time for doing so. Accordingly,

this rulemaking serves the purpose of

fulfilling this requirement to promulgate

the date-of-enactment designations,

coupled with the requirements discussed

below, to promulgate the classifications

and boundaries for these areas.

ii. Boundaries. As noted above,

section 107(d)(1)(C) requires that each

area designated preenactment of the

CAAA be designated again, by

operation of law, in the same fashion.

Because the specific boundaries of the

areas are to be determined

subsequently, as described below, EPA

interprets the section 107(d)(1)(C)

requirement as generally specifying that

the appropriate areas be designated, but

not necessarily as solidifying their preenactment boundaries. For example, as

of the date of enactment, the Tampa,

Florida, area became designated

nonattainment, but the specific

boundaries of that area were to be

determined subsequently.

Nevertheless, for certain purposes,

each area designated by operation of

law under section 107(d)(1)(C) retained

its preenactment boundaries at the date

of enactment. For example, locations

within a metropolitan area that were

designated nonattainment at enactment

remained subject to the nonattainment

new source review (NSR) requirements

of the NSR programs EPA had

previously approved for the

nonattainment areas (under Part D of

Title I of the Clean Air Act prior to the

CAAA). The preenactment boundaries

are identified in the version at 40 CFR

part 81, Subpart C-Section 107

Attainment Status Designations (part 81

tables), preceding the enactment of the

CAAA.

(af iii. General Classificationslother -As described treatmen in this ssection, all areas dwith certain

exceptions designated nonattainment

by operation of law as of the date of

enactment were classified as of the date

of enactment in accordance with air

quality.

Section 181(at(1y provides:

Each area designated nonattainment for ozone pursuant to section 107d) shall be

classified at the time of such designation

under table 1, by operation of law, as a

Marginal Area, a Moderate Area, a Serious

Area, a Severe Area, or an Extreme Area

based on the design value for the area.

Section 186(a)(1) includes an identical

,provision for CO areas (except that the

classifications are limited to moderate or serious). Based on these provisions, EPA has

taken the position that classifications

for areas designated nonattainient

prior to enactment occurred at the same

time that those areas were designated

by operation of law as nonattainment

under section 107d1(C}i), which was

the date of enactment. As discussed

below, EPA has taken the position that,

for metropolitan areas that included at

least some locations designated

nonattainment at enactment, such

classification is not delayed until the

time of the designations required to be

promulgated 240 days after enactment

under section 107[d4n(Ae(ii).

For ozone, classification is to be

based on the following table of design

Values (section 181(a)(1), table 1):

Area classification Areaclasifictionmillion) Design value (parts per

Marginal .............................. 0.121 up to (but not

including) 0.138

Moderate ............................. 0.138 up to (but not

Including) 0.160

Serious ................................ 0.160 up to (but not

Including) 0.180

Severe-15 ............................ 0.180 up to (but not

including) 0.190

Severe-17 ......... 0.190 up to (but not

including) 0.280

Extreme ............................... 0.280 and above

Severe-15 and -17 areas (EPA's

nomenclature] face the same

requirements but differ in their

attainment dates (15 years for severe-15;

17 years for severe-17). Severe-17

applies to areas with a design value of

.190 to .280 for ozone years 1986-1988.

For CO, classification is to be based

on the following table of design values

(section 186(a)(1), table 3):

Area classification Design value (ppm)

Moderate-i .......................... 9.1-12.7

Moderate-2 .......................... 12.8-16.4

56,696 , .Federal Register/Vol. 56, No. 215/Wednesday, November 6, 1991/Rules and Regulations
Federal Register/Vol. 56, No. 215/Wednesday, November 6, 1991/Rules and Regulations

Area classification Design value (ppm).

Serious ................................ 16.5 and above

EPA is distinguishing moderate-1 from

moderate-2 (EPA's nomenclature)

because of the significant additional

regulatory requirements for those areas

with a design value above 12.7 ppm.

For both ozone and CO. the design

value is to be calculated according to

"the interpretation methodology issued

by the Administrator most recently

before the date of the enactment" of the

CAAA. This methodology is contained

for the most part in a memorandum from

William Laxton, Director, Technical

Support Division, the Office of Air

Quality Planning and Standards, dated

June 18, 1990 ("Laxton Memorandum").

This memorandum is contained in the

TSD, item #1.

Section 181(a)(3) requires the

publication in the Federal Register of

ozone classifications at the time of the

publication of the notice under section

107(d)(4) (concerning designations).

Section 186(a)(2) includes a comparable

requirement for CO. This rulemaking

fulfills those requirements. -

A listing of the classifications as they

stood at the date of enactment can be

found in the pre-CAAA 40 CFR part 81

tables mentioned previously.

(b) Years of data. The primary years

the EPA used for purposes of

designations and classifications

pursuant to this notice were 1987-1989

(3-year period) for ozone and 1988-1989

(2-year period) for CO.

In some cases, the EPA used complete

1988-1990 (ozone) or 1989-1990 (CO) data

if they were quality assured and

publicly available in the AIRS

[Aerometric Information Retrieval

System (EPA's National Air Quality

Database)] by February 13, 1991, and the

State requested the EPA to use it:

For areas designated attainment prior

to enactment, the EPA relied on 1990

data (if quality assured and in AIRS by

February 13, 1991) to continue an

attainment designation in cases where

an area violated the standard during the

primary ozone or CO years, but then

revealed attainment once again using

1990 data.

There are several reasons why the

EPA began with the data years 1987-

1989 for ozone and 1988-1989 for CO.

The CAA required the Administrator to

make a determination for 5 percent

classification downshifts no later than

90 days after enactment (February 13,

1991). No later than 180 days after

enactment (May 15, 1991), the EPA was

required to notify States of its intent to

diesignate areas. Although some areas

had 1990 data available as early as

February 13, 1991 and EPA considered

it, most areas did not. Thus, in order to

meet the deadlines set forth in the Act

the EPA was compelled for timing

purposes to use 1987-1989 for ozone and

1988-1989 for CO as primary data years

in determining designations and

classifications pursuant to this notice.

(c) Other treatment. Some

nonattainment areas were not classified

in accordance with the classification

tables under section 181(a)(1) or

186(a)(1) because of specific statutory

provisions or because their air quality

values did not accord with the

classification tables. -

(1) Submarginal. The EPA has

determined to treat certain ozone

nonattainment areas as "submarginal."

This category includes areas that

violated the ozone standard during 1987-

1989 and that had a design value during

the relevant period of less than .121

ppm. The submarginal. category can

occur when there is not a complete set

of data so that the expected exceedance

rate is higher than the NAAQS

exceedance rate of 1.0 per year even

though the estimated design value is less

than the level of the standard. More

discussion of EPA's data requirements is

contained in the TSD, item #2.

The SIP submittal requirements of

section 182 (concerning ozone) do not

apply to these areas. A detailed

discussion of these requirements will

appear in the Title I General Preamble

in a Federal Register scheduled for

January 1992 publication.

(2) Transitional. Section 185A

provides that an area designated

nonattainment by operation of law

under section 107(d)(1)(C)(i) (by virtue of

its designation asnonattainment prior to

enactment of the CAAA), which "has

not violated the [NAAQSI" for ozone

during the 1987-1989 period is to be

treated as a transitional area. Section

185A further requires EPA to determine,

by June 30, 1992, based on the

transitional area's "design value as of

the attainment date" whether the area

attained the NAAQS by December 31,

1991.

The EPA interprets this provision to

require EPA to use its standard methods

for determining attainment or

nonattainment to ascertain whether an

area is a transitional area and to

determine whether the area attained the

NAAQS by December 31, 1991. There

must be sufficient data (75 percent

completeness for each year) to

determine that the area has not violated

the standard. A brief discussion of these

procedures is included in the TSD, item

#3.

(3) Ozone incomplete data areas.

Certain ozone areas designated

nonattainment prior to enactment do not

have sufficient air quality monitoring

data to determine whether they are or

are not violating the NAAQS. Under

these circumstances, the EPA does not

believe sufficient data (75 percent

completeness for each year) exist to

warrant a classification for the area.

The EPA terms these areas "Incomplete

Data Areas."

As a result, the SIP submittal

requirements of section 182 (concerning

ozone) do not apply to these areas. A

detailed discussion of these

requirements will appear in the Title I

General Preamble in a Federal Register

scheduled for January 1992 publication.

(4) CO "not classified" areas. Certain

CO areas are designated nonattainment

by operation of law as of the date of

enactment by virtue of their

preenactment designation of

nonattainment. These areas did not

experience a violation of the 1988-1989

NAAQS. Where there was inadequate

monitoring or insufficient data, EPA

looked at historical trends to determine

whether the area would have violated

the NAAQS in 1988-1989. Where EPA

concluded there would have been a

violation, the area was classified

appropriately. Where EPA believed

there would not have been a violation,

the area was "not classified."

As a result, the SIP submittal

requirements of section 187 (concerning

CO) do not apply to these areas. A

detailed discussion of these

requirements will appear in the Title I

General Preamble in a Federal Register

scheduled for January 1992 publication.

(5) Rural transport areas (ozone).

Section 182(h) sets out general criteria

for determining whether an area

qualifies as a rural transport area. The

statute defines it as an area which is

designated nonattainmcnt and neither

includes nor is adjacent to any part of a

C/MSA. In such cases, the

Administrator in his discretion may

treat the area as a rural transport area

based on a finding that the emissions

within the area do not make a

significant contribution to the ozone

concentrations measured in the area or

in other areas.

For specific criteria in determining

when an area is a rural transport area,

refer to the procedures contained in

technical document # EPA 450/4-91-015,

."Criteria for Assessing the Role of

Transported Ozone/Precursors in Ozone

Nonattainment Areas."

This section also provides that a rural

transport area, regardless of its

classification, is treated as meeting the

56697
56698 Federal Register/Vol. 56, No. 215/Wednesday, November 6, 1991/Rules and Regulations

applicable requirements of section 182

(generally relating to submissions

required for ozone areas classified from

marginal to extreme) if the area meets

the submission requirements of a

marginal area. The thrust of this provision is to allow

a rural transport area, the design value

of which would otherwise indicate a

classification for the area of moderate or

higher, to be treated as a marginal area.

3. Enactment + 45 days: C/MSA

boundary process begins-general

requirements. Section 107(d)(4)(A)(iv)

provides that areas designated

nonattainment at the date of enactment,

and classified as serious or higher,

would, by operation of law 45 days after

the classification, take as their

boundaries the MSA or C/MSA, unless

the State submitted a letter before that

date indicating that it wished to study

the boundary question further. Because areas designated nonattainment by

operation of law at the date of

enactment were also classified at that

time, as described above, this 45-day

period began from the date of enactment

and ended on December 30, 1990.

Areas for which no 45-day letter was

submitted took as their boundary the

larger of their preenactment boundaries

or the C/MSA. These areas are

identified in section 8a(1) of this

document.

Areas for which a 45-day letter was

submitted are identified in the TSD, item.

#4, and copies of the letters are in

Docket A-90-42. For these areas, the

State was given the opportunity to

submit to EPA a study describing why

parts of the C/MSA should not be

included in the nonattainment area. In

letters from EPA to the relevant State air

agency directors, EPA urged that the

States submit their analyses by March

15, 1991, and requested that the study be

completed by, at the latest, August 13,

1991. If EPA concurs in the finding,

based on the State study, by 14 months

after classification (January 15, 1992),

the boundaries will be reduced

accordingly. If EPA does not concur by

that date, the boundaries will become

the C/MSA by operation of law.

4. Enactment + 90 days: 5percent

classification adjustment-a. General.

Under sections 181(a)(4) and 186(a)(3),

an ozone or CO nonattainment area may

be reclassified to the next higher or lower classification if its design Value

places it within 5 percent of the next

classification. For ozone, section

181(a)(4) provides that such

reclassification must occur no later than

90 days after the initial classification,

which is (1) 90 days after the date of

enactment (by February 13, 1991) for

areas designated nonattainment by

operation of law under section

107(d)(1)(C) (by virtue of their

designation as nonattainment

preenactment); or (Z) 90 days after the

effective date of this rule for areas

designated nonattainment for ozone for

the first time pursuant to this rule (by

virtue of their designation as attainment

preenactment). For CO, section 186(a)(3)

provides that such reclassification must

occur no later than 90 days after

enactment. The provisions grant the

Administrator broad discretion in

making, or determining not to make, the

reclassification.

b. EPA criteria. Section 181(a)(4)

provides general guidelines in

determining whether an area qualifies

for a classification adjustment:

In making such adjustment, the

Administrator may consider the number of

exceedances of the national primary ambient

air quality standard for ozone in the area, the

level of pollution transport between the area and other affected areas, including both

intrastate and interstate transport, and the

mix of sources and air pollutants in the area.

The EPA has developed more specific

criteria (discussed below) to evaluate

whether it is appropriate to reclassify a

particular area. These criteria are

primarily applicable to downshifts. The

EPA approved downshifts when the

area met the first requirement (a request

by the State to EPA) and at least some

of the other criteria (emissions,

reductions, trends, etc.) and did not

violate any of the criteria.

Request by State: EPA did not

exercise its authority to downclass (or

upclass) areas on EPA's own initiative.

Rather, EPA requested that the State

submit a request for a downshift.

Discontinuity- A 5-percent downshift

must not result in an illogical or

excessive discontinuity relative to

surrounding areas. In particular, in light

of the area-wide nature of ozone

formation, a downshift should not create

a "donut hole" where an area of one

classification is surrounded by areas of

higher classification.

Attainment: Evidence should be

available that the proposed area would

be able to attain by the earlier date

specified by the lower classification.

Emissions reduction: Evidence should

be available that the area would be very

likely to achieve the appropriate total

percent emission reduction necessary in

order to attain in the shorter time

period.

Trends: Near- and long-term trends in

emissions and air quality should support

a downshift. Historical air quality data

should indicate substantial air quality

improvement. Growth projections and

emission trends should support a - downshift. Vehicle miles traveled (VMT)

and other indicators of emissions should

not be increasing at higher than normal

rates.

Years of data: For ozone, the 1987-

1989 period is central to determining

classification. Years of data after 1989

may be employed to corroborate the

validity of a downshift. However, later

years of data should not be the sole

foundation for downshifts.

Only one downshift is allowed,

meaning, if downclassed, an area cannot

present data from other years as

justification for a second downclass.

Under no circumstances can the use

of 1990 air quality data be used to

redesignate an area from nonattainment

to attainment. For redesignation to

attainment, the area must meet all of the

requirements of section 107(d)(3)

(including a maintenance plan).

c. EPA action. Areas requesting a

downshift per section 181(a)(4) and

EPA's response to those requests are

contained in the TSD, item #5.

d. Reclassifications upward. Section

181(b)(3) provides that EPA shall

automatically grant the request of any

State to reclassify an ozone

nonattainment area to a higher

classification. This requirement requires

EPA to "publish a notice in the Federal

Register of any such request and of any

action by the Administrator in granting

such request."

On December 27, 1990, EPA received a

request from the State of Maine to

reclassify Lincoln County upward from

marginal to moderate. By this notice,

EPA is granting that request.

On December 28, 1990, EPA received a

request from the State of California to

reclassify Ventura County from serious

to severe. Ventura County is part of the

Los Angeles C/MSA, which is classified

as extreme, and California has

requested (pursuant to the 45-day/14-

month process described above) that

Ventura County be treated as a separate

nonattainment area. California's request

to reclassify Ventura County to severe is

based on an assumption that Ventura

County would be treated as a separate

nonattainment area. As discussed

below, EPA is, by this notice, approving

California's request to treat Ventura

County as a separate area classified as

severe.

Section 182(b)(3) does not by its terms

place time limits on the opportunity of a

State to request a voluntary

reclassification upward. Accordingly,

States may continue to submit such.

requests. However, such reclassification

will not delay the SIP/submittal dates

otherwise applicable under subpart 2 o'

Title I of the CAAA.
Federal Register/Vol. 56, No. 215/Wednesday, November 6, 1991/Rules and Regulations

5. Enactment + 120 days: State

submits list of all areas-general.

Section 107(d)(4)(A)(i) requires States to

submit a list designating, redesignating,

or affirming the designation of all areas

of the State as nonattainment,

attainment, or unclassifiable for ozone

and CO by 120 days after enactment.

Virtually all the States met this

requirement on a timely basis. Copies of

the States' 120-day letters are included

in Air Docket A-90-42.

For areas designated nonattainment

at the date of enactment of the CAAA,

and classified as marginal or moderate,

this list must include the boundaries of

the areas.

For areas designated nonattainment

at the date of enactment of the CAAA,

and classified serious or above, and for

which the Governor submitted a 45-day

letter, EPA encouraged the States to

submit their supporting analyses as soon

as possible, and EPA stated that if

possible, EPA would make a

determination by this notice instead of

by January 15, 1992 (the statutorily

prescribed deadline). Several States did

submit their boundary analyses

sufficiently early to allow EPA to take

action in this document. The actions

EPA is taking on the boundaries for

these States are discussed later in this

document and in more detail in the TSD.

For areas designated attainment or

unclassifiable at the date of enactment,

States were required to redesignate

these areas to nonattainment if their

current air quality revealed

nonattainment. These areas are

identified in Part III. The applicability to

these areas of the opportunity for the 5

percent reclassification and, in the case of areas classified serious or higher, the

C/MSA boundaries procedure, is

described below. Although for these

areas this procedure for reclassification

and boundary determinations may take

place after the classification, which is

occurring by this notice, EPA requested

in letters sent to the States in January

that any affected States submit with

their 120-day (March 15) submittals any

analyses supporting a reclassification or boundary revision, and EPA would

consider taking final action on these

issues with today's notice.

6. Enactment + 180 days: EPA

notifies States of intent to modify

suggested designations for certain

areas. Section 107(d)(4)(A)(ii] and

(1)(B)(ii) provides that EPA may modify

the designations, classifications, and

boundaries submitted by the State at 120

days, but that if EPA intends to do so, it

must notify the State of EPA's proposed

modifications at least 60 days prior to

EPA promulgalion.

By letters dated on or about May 14,

1991 (at least 60 days before the

promulgations and announcements set

forth in this document), EPA proposed

modifications to various State

submissions. These modifications are

summarized later in this document and/

or in more detail in the TSD.

7. Enactment + 200 days: States

respond to EPA's proposed

modifications. Consistent with section

107(d)(4)(A)(ii) and (1)(B)(ii), EPA

provided the affected States with an

opportunity to demonstrate why any of

EPA's proposed modifications were

inappropriate. The EPA requested that

the affected States submit such

demonstrations by June 3, 1991, so that

EPA could meet the statutory deadline

for promulgation of final designations,

classifications, and boundaries. The

States' responses are included in Air

Docket A-90-42.

8. Enactment + 240 days. This section

describes the actions EPA is taking with

this notice.

Under section 107(d)(4)(B)(ii), EPA is

required to promulgate the new,

affirmed, and reaffirmed designations,

including boundaries, for areas

designated nonattainment, attainment,

or unclassifiable with respect to ozone

and CO. The EPA is taking that action

with this notice. This section discusses

those actions in several separate parts:

(1) Areas designated nonattainment at

date of enactment-classified serious

and higher.

(2) Areas designated nonattainment at

date of enactment-ozone areas

classified marginal or moderate and CO areas classified moderate.

(3) Other areas designated

nonattainment at the date of

enactment-treated separately from the

classified areas.

(4) Areas designated entirely

attainment/unclassifiable at enactment,

but now redesignated to nonattainment.

(5) Areas designated attainment/

unclassifiable at enactment and that

now retain that designation.

a. Ozone and CO areas designated

nonattainment at date of enactment--

classified serious and higher. With

respect to areas designated

nonattainment for ozone or CO at

enactment and classified serious or higher, and for which the Governor did

not submit a 45-day letter, the area took

as its boundaries, 45 days after

enactment, the larger of their

preenactment boundaries or the C/MSA

boundary. Today's notice affirms those

boundaries. Any areas not included in

the boundaries of these nonattainment

areas pre-enactment, but now included

within the nonattainment boundaries by

virtue of the expansion of the

nonattainment area to include the C/

MSA, are generally treated as having

been designated and classified on the

date of enactment, as described below.

With respect to areas designated

nonattainment for ozone or CO at

enactment, classified serious or higher.

for which the Governor submitted a 45-

day letter (thereby beginning the C/

MSA boundary-determination process)

and has submitted the relevant

boundary data, this notice promulgates

these boundaries.

(1) EPA Actions:

Following are the serious and higher

classified areas for which the entire C/

MSA was already designated at

enactment by operation of law (because

the preenactment boundaries of the

nonattainment area included the C/

MSA), or the remaining attainment

areas were added by the State. (See Air

Docket No. A- 90-42 for official

designation correspondence between

the States and EPA on each area.) In

addition, for two areas, the Washington,

DC, MSA and Philadelphia CMSA, the

entire C/MSA is designated due to

absence of a 45-day letter from the State

requesting more time to evaluate

boundaries (Stafford Co., VA, became

part of the Washington, DC,

nonattainment area and Cecil Co., MD,

became part of the Philadelphia

nonattainment area).

San Diego, CA

San Joaquin Valley, CA

Philadelphia, PA-NJ-MD-DE

Washington, DC-MD-VA

Baton Rouge, LA

Boston, MA

Greater Connecticut (New London

portion)

New York City (New Jersey portion)

Springfield, MA

Beaumont, TX

El Paso, TX

Houston, TX

Milwaukee, WI

Sheboygan, WI

The San Joaquin Valley, CA, area

includes the MSAs of Bakersfield,

Fresno, Visalia-Tulare-Porterville,

Modesto, Merced, and Stockton, and the

counties of Kings and Madera. The

Greater Connecticut nonattainment area

consists of the Hartford-New BritainMiddletown CMSA, the Waterbury, CT,

MSA, the New London-Norwich, CT-RI,

MSA, and the New Haven-Meriden, CT,

MSA, including some of the previous

planning areas in the State.

By this notice EPA is promulgating the

boundaries of the following seven areas

as smaller than the C/MSA. For these

areas, the portions of the C/MSA not

included in the nonattainment area

56699
56700 Federal Register/Vol. 56, No. 215/Wednesday, November 6, 1991/Rules and Regulations

become either (1) separate

nonattainment areas with a lower

classification, or (2) adjoined to another,

contiguous nonattainment area with the

same or lower classification. The States

and EPA are in agreement with respect

to these actions. Under section

107(d)(4)(A)(v), EPA may promulgate

boundaries smaller than the CIMSA if it

concurs with a State finding that sources

in the excluded portion "do not

contribute significantly" to the violation

of the NAAQS. This provision identifies

several factors that may be considered.

In general, EPA supports its decision

to concur with the State's finding with

respect to these areas on the basis of a

facts-and-circumstances test that

focused on whether sources in the area

at issue contributed significantly to'

NAAQS violations in the C/MSA. The

EPA did not develop bright-line criteria,

but instead, examined such factors as

the amount of emissions from within the

area at issue and its percentage

contribution to the CIMSA (or

surrogates for emissions data, such as

population] and if available, the results

of modeling studies.

Baltimore. MD-Kent and Queen

Annes Counties become a separate

marginal nonattainment area.

Los Angeles, CA-Ventura County

becomes a separate severe-15 area.

Southeast desert modified (AQMA)

becomes a separate severe-17 area.

Portsmouth, NH-ME-The Maine

portions of Portsmouth become part of

the Portland, Maine, nonattainment

area.

Chicago, IL-Kenosha County

becomes part of the Milwaukee-Racine

nonattainment area.

New London-Norwich MSA (Rhode

Island portion)-Westerly and

Hopkington become part of the

Providence nonattainment area.

New York City (Connecticut

portion)-Ansonia City, Beacon Falls

Town, Derby City, Milford City, Oxford

Town, Seymour Town and Shelton City

become part of the Greater Connecticut

nonattainment area.

Boston, MA-All Massachusetts

towns which were previously part of the

Providence CMSA become part of the

Boston nonattainment area.

In addition, EPA believes that it may

concur in reassignment of a portion of

the C/MSA to another nonattainment

area when that reassignment results in

the same, or essentially the same,

classification-under the de minimis

authority of Alabama Power Co. v.

Costle, 636 F.2d 323, 360-61, 404-05 (DC

Cir. 1980). This case held that EPA may

exempt de minimis situations from a

statutory requirement when the burden

of regulation would yield little or no

value. In these cases, EPA believes that

applying the "contributes significantly"

test to these areas would yield no gain

in air quality since control requirements

remain the same despite the

reassignment, and thus neither area's

prospects for reaching attainment and

maintenance is jeopardized. Applying de

minimis authority to these cases

remains consistent with the underlying

purpose of the nonattainment

provisions, which is to assure

attainment and maintenance of the

NAAQS. (See the TSD, item #8, for

technical documentation supporting

these determinations.)

In addition, by this notice EPA is

promulgating the boundaries of the

following five areas as smaller than the

C/MSA. For these areas, the removed

portions of the C/MSAs remained

attainment. (See the TSD, item #7, for

technical documentation supporting

these determinations.) Following is a

listing of the C/MSAs and the counties

which remain attainment. The States

and EPA are in agreement with respect

to these actions.

Ozone

Atlanta, GA-Butts. Barrow, Newton,

Spaulding and Walton Counties remain

attainment.

Los Angeles, CA-The southeast

desert portion (eastern Riverside County

and northern and eastern San

Bernardino County) of the LA CMSA

remains attainment.

Sacramento, CA-The Lake Tahoe Air

Basin portions of El Dorado and Placer

Counties remain attainment.

Chicago, IL-Portions of Kendall and

Grundy Counties remain attainment.

CO

Los Angeles, CA-All of Ventura

County and the southeast desert

portions of Los Angeles, Riverside, and

San Bernardino Counties remain

attainment.

For the following serious areas, States

requested in a letter (45-day letter) more

time to evaluate their boundaries per

section 107(d)[4)(A)[iv). The

Administrator has not yet made a

finding on these two areas.

Muskegon, MI.

New York City (Orange and Putnam

Counties, NY).

In a May 14, 1991 letter to these

States, EPA requested that all

documentation pertaining to any

proposed boundary changes be

submitted as soon as possible, but no

later than August 12, 1991.

New York State followed with a letter

on June 4, 1991, requesting more time to

evaluate the boundaries of Orange and

Putnam Counties and informed EPA that

the appropriate documentation would be

submitted no later than the August 12.

1991 deadline.

The State of Michigan confirmed its

intent to continue studying its Muskegon

boundary issue in a June 18, 1991 letter

to EPA.

On January 15. 1992. nonattainment

boundaries will become the entire Cl

MSA for both the New York and

Michigan areas discussed above unless

the Administrator has concurred with

the Governors' finding that a smaller

boundary is more appropriate. The EPA

is awaiting the State's studies. The final

determinations will be promulgated in a

separate Federal Register notice.

b. Ozone and CO areas designated

nonattainment at date of enactmentclassified marginal or moderate-i.

Designations. For areas designated

nonattainment for ozone or CO by

operation of law under section

107(d)[1)(C) at the date of enactment,

EPA, with today's action, reaffirms that

designation. Section 107(d)(4)(A)(iii)

precludes redesignating an area to

attainment under this 240-day process.

ii. Boundaries. At a minimum, the

nonattainment boundaries should

include those areas designated

nonattainment prior to enactment. For

purposes of determining sources subject

to new source review, this preenactmen'

boundary applies. Where it may be

appropriate to expand the

nonattainment boundary beyond the

existing boundary, States should treat

these additional areas as subject to the

appropriate other CAA requirements. -

Section 107(d)(4)(A)(i)-(iij authorizes

EPA to promulgate a designation of "nonattainment" for an area. Section

107(d)(1)(A)(i) defines a nonattainment"

area asany area that does not meet (or that

contributes to ambient air quality in a nearby

area that does not meet) the [NAAQSJ.

This provision bases the

determination of whether an area is

nonattainment on air quality

considerations-if the air quality of an

area violates the NAAQS, or if sources

in that area contribute to NAAQS

violations in a nearby area, the area

must be designated nonattainment.

However, the provision does not by its

terms specify criteria for determining the

extent to which source contributions

mandate designation as nonattainment.

Accordingly. the statute grants EPA

discretion in making this determination.

Section 107(d)(1)(A) and (B)(i) and (ii)

and 107(d)(4)(A)(i) and (ii) requires the

State to submit a list of all areas in the

State, with its designations, and
Federal Register/Vol. 56, No. 215/Wednesday, November 6, 1991/Rules and Regulations

authorizes EPA to make "such

modifications as the Administrator

deems necessary to the designations of

the areas (or portions thereofn * * *

(including to the boundaries of such

areas or portions thereof)."

These statutory provisions provide

guidance for the determination of

whether an area is to be designated

nonattainment. They do not, however,

provide explicit criteria for determining

the specific boundaries of the

nonattainment area. They do not

specifically address the issue of whether

a geographic area designated

nonattainment must be one

nonattainment area, or whether the

State or EPA may divide that area into

two or more nonattainment areas.

Accordingly, the statute grants EPA

discretion in making this determination.

The EPA will grant a strong

presumption in favor of the designations

and boundaries put forth by the States.

The EPA believes that this is an

acceptable approach since by definition,

the nonattainment areas classified as

marginal and moderate have less severe

ozone or CO problems and are likely to

reach attainment through Federal

measures which generally apply

independent of boundaries.

Accordingly, EPA has determined in

most cases to accept the State-proffered

designations and boundaries. In general,

EPA is not discussing in this document

or in the TSD, designations, boundaries,

and/or classifications issues where EPA

is in agreement with the State's request.

However, where EPA is disagreeing

with a State's proposed action, a

detailed discussion of the issue,

including EPA's reasons, follows.

The EPA, in several instances, is still

studying whether to expand ozone

nonattainment areas within a C/MSA to

include additional counties in that C/

MSA when those counties may be of

such great population or such a large

percentage of the C/MSA's population

that sources in those counties may be

contributing to the nonattainment

problem in the C/MSA. These counties

are: Pasco County, in the Tampa,

Florida, MSA; Washington County in the

Parkersburg-Marietta, Ohio, MSA. For

these areas, as noted in the

accompanying tables of this document,

the listed designation does not reflect

EPA action under section 107(d)(4)(A).

At the date of enactment of the CAAA,

these two counties were designated

attainment, by operation of law, under

section 107(d)(1)(C). The State and EPA

are reviewing whether to confirm or

reverse their present designation under

the process set out under section

107(d)(4)(A) and will publish a separate

noticc to that effect.

In a number of instances occurring

across the nation, counties that may

generally be considered to be rural due

to relatively small populations and a

relatively low degree of urbanization

have contained a monitor that has

recorded an ozone NAAQS violation. In

some of these instances, the States, in

the 120-day submissions of the lists of

areas, elected not to designate these

areas as nonattainment. In these cases,

EPA informed the State in EPA's 180-

day letter that such counties (or

subcounties) must be designated as

nonattainment on the grounds that

section 107(d)(1)(A)(i) defines a

nonattainment area as, among other

things, "any area that does not meet...

the [NAAQSI."

Some States did not wish to designate

the entire county. In these cases, EPA

generally agreed to designate only a

portion of the county nonattainment. To

determine the boundaries of these

nonattainment areas, or the extent to

which neighboring nonattainment areas

should be expanded to include all or

part of these counties, EPA has

determined to apply the following

criteria.

Presumptively, the nonattainment

area should include the entire county. If

the county does not adjoin any

nonattainment area, the presumption in

favor of an entire county is stronger. The

boundaries may be reduced to less than

an entire county if it is possible to

delineate the boundaries of the area

involving the NAAQS violation, and if it

can be shown that certain other areas

within the county likely do not

contribute to the NAAQS violation.

In particular, if a county adjoins a

nonattainment area, the presumption in

favor of designating the entire county

nonattainment may be rebutted, and

EPA will designate boundaries narrower

than the entire county, in accordance

with the following criteria.

The portion of the county designated

nonattainment must be contiguous with

the adjoining nonattainment area,

include the area surrounding the

monitor, and include all adjoining areas

with populations of sufficient density

such that these areas are likely to

contribute to the NAAQS violation.

Further explanation of these criteria and

of their application to individual cases is

included in the TSD, item #8.

Based on these criteria, EPA is today

promulgating the following

nonattainment areas:

Ozone

North Carolina

On May 13, 1991, EPA Region IV

wrote to Governor Martin (180-day

letter) recommending that a portion of

-Davie County (Greensboro MSA) and

Granville County (Raleigh-Durham

MSA) be designated nonattainment for

ozone based on available monitoring

data.

Based on population and emission

data provided by the State of North

Carolina, EPA believes that emissions

originating in the counties of Davie and

Granville do not merit inclusion of each

entire county as nonattainment.

However, since these counties have

monitored violations of the NAAQS, at

least a portion of the county must be

designated nonattainment. The EPA is

therefore designating areas smaller than

the counties as nonattainment for Davie

and Granville Counties. The boundaries

chosen for each of the areas include the

monitor and an area that includes the

more urbanized portions of the county

that is contiguous with the rest of the

nonattainment area (the GreensboroHigh Point-Winston-Salem MSA for

Davie County; and the Raleigh-Durham

MSA for Granville County). The

rationale for this action is that this

boundary includes the area in which the

air quality is nonattainment and in

which sources likely to contribute to the

nonattainment problem are located.

South Carolina

The Cowpens monitor in the

northwest comer of Cherokee County

(non-MSA) measured violations of the

NAAQS during the 1987-1989 period and

therefore must be designated

nonattainment. Since there is

uncertainty at this time as to the origin

of the source of the emissions causing

the violations in Cherokee County, and

EPA believes that there is no basis for

designating the nonattainment area as

less than a county, the entire county is

being designated nonattainment.

(Cherokee County is contiguous to the

Charlotte MSA to the northeast and the

Greenville-Spartanburg MSA to the

southwest.)

Kentucky

The EPA is today designating portions

of the following five counties in the

Commonwealth of Kentucky for the

same reasons as the North Carolina

counties discussed above: Livingston

County (Paducah, non-MSA); Greenup

County (Huntington-Ashland MSA);

Oldham County (Louisville MSA); Bullitt

County (Louisville MSA); and Hancock

County (Owensboro MSA).

Since there is uncertainty at this time

as to the origin of the source of the

emissions causing the violations in a

sixth county-Edmonson County

(Bowling Green non-MSA)-the entire

56701 I
56702 Feaeral Register/Vol. 56, No. 215/Wednesday, November 6, 1991/Rules and Regulations

county is designated nonattainment and

classified as a rural transport area. (See

the TSD, item #9, for documentation

supporting a rural transport

classification.)

Virginia

Virginia proposed that Charles City

County (Richmond MSA] and the City of

Suffolk (Norfolk MSA) remain

attainment By today's notice, EPA is

designating both of these counties as

nonattainment because of monitored

violations within them.

CO

New Jersey

The State of New Jersey stated in a

letter dated June 28, 1991, that, while it

is willing to accept EPA's nonattainment

boundaries for CO, it requests that these

nonattainment areas be classified as

"low moderate" (12.7 ppm and below).

The EPA believes that the

nonattainment area is comprised of the

contiguous jurisdictions of New York

City, Nassau and Westchester Counties

in New York, and Bergen, Hudson,

Essex and Union Counties and the cities

of Passaic, Clifton and Paterson in New

Jersey. The highest CO concentrations

measured within this area are in

Manhattan, in the center of the

metropolitan area. The measured

concentration places the area in the

"high moderate" category. Since

vehicles commute throughout the entire

area and a certain proportion have

Manhattan as their destination, these

vehicles have the potential to contribute

to the maximum measured levels.

The New Jersey counties in the area

rank among the State leaders in such

categories as vehicle miles traveled and

population density per square mile.

These New Jersey counties are not

distinguishable from the New York

counties surrounding Manhattan.

Therefore, based on this rationale and

the measured concentrations in

Manhattan (13.5 ppm), the northern New

Jersey portion of the New York-New

Jersey-Long Island CMSA

nonattainment area retains the same

classification (high moderate) as the

CMSA, which includes northern New

Jersey.

Tennessee

On March 12, 1991, Governor

McWherter and Commissioner Luna

submitted the recommendation that the

City of Memphis be designated as a

moderate nonattainment area for CO.

The City of Memphis was designated

nonattainment for CO prior to

enactment of the CAAA.

On May 13, 1991, in a letter to

Governor McWherter, EPA

recommended that the CO

nonattainment area be expanded from

the City of Memphis to all of Shelby

County. This designation is based on

contribution to the mobile source CO

emissions in the portion of Shelby

County outside of the City of Memphis,

and on the practical problems of

attempting to administer a partialcounty rather than countywide

automobile inspection and maintenance

(I/M) program.

The mobile source contribution from

vehicles in the portion of Shelby County

outside of the City of Memphis is 132

tons per day, or 26 percent of the total

CO emissions from mobile sources in

Shelby County. Currently, the I/M

program is required only for the City of

Memphis. Since automobile registration

is done on a countywide basis without

regard to whether or not the vehicle is

located within the City of Memphis, it is

difficult if not impossible to verify

whether the appropriate vehicles are

actually subject to the I/M program. The

expansion of the nonattainment area to

the entire county will give the State a

basis for expanding coverage of the I/M

program.

On May 31, 1991, Commissioner Luna

wrote a letter to EPA Regional

Administrator Greer Tidwell disagreeing

with the Region's proposed boundaries

for the ozone nonattainment areas in

Tennessee. In that letter, there was no

comment on EPA's proposal to expand

the Memphis CO nonattainment area.

Utah

The EPA is still studying whether to

expand the Provo CO nonattainment

area. As noted in the accompanying

tables of this document, the listed

designation does not reflect EPA action

under section 107(d)(4)(A). At the date

of enactment of the CAAA, that portion

of Utah County outside the city limits of

Provo was designated attainment by

operation of law under section

107(d)(1)(C). The State of Utah and EPA

are reviewing whether to confirm or

reverse their present designation under

the process set out under section

107(d)(4)(A) and will publish a separate

notice to that effect.

iii. Classifications. Areas designated

nonattainment by operation of law at

the date of enactment were classified at

that time, and by today's notice, EPA is

announcing the classifications as

required under sections 107(d)(4)(AI(ii),

107(d)(2), 181(a)(3), and 186(a)(2). Areas

designated nonattainment at the date of

enactment are not being classified anew

by today's notice: rather, that

classification occurred at the date of

enactment, and EPA today is merely

announcing and codifying in the CFR the

classifications that occurred for these

areas at enactment. -

The EPA bases this approach

primarily on the provisions of section

181(a)(1) and section 186(a)(1), each of

which provides (in relevant part, using

identical terms): "Each area designated

nonattainment... pursuant to section

107(d) shall be classified at the time of

such designation." Section

107(d)(1)(C)[i) provides that each ozone

and CO preenactment nonattainment

area is "designated, by operation of law,

as a nonattainment area." This

designation occurred at the date of

enactment. -

The fact that classification occurred at

the date of enactment means that the

clock began ticking on the date of

enactment for certain events triggered

by the classification, specifically, the

90-day opportunity for 5 percent

reclassification, and the 45-day period

for States to submit requests to study

.the boundaries of areas classified.

serious and higher. For CO

nonattainment areas, section 186(a)(3)

provides that the 5 percent

reclassification must occur "within 90

days after the date of the enactment"

thereby confirming that classification for

CO under section 186(a)(1) occurred on.

the date of enactment. Because the

relevant provisions of section 181(a)(1)

for ozone are identical to the section

186(a)(1) CO provisions, section

186(a)[3) implies that classification for

ozone also occurred on the date of

enactment, at least for areas containing

locations designated nonattainment at

enactment. The House Committee

Report confirms this view by stating that

the 5 percent reclassification adjustment

for ozone may occur "{Iwjithin 90 days of

enactment" [H.R. No. 101-490, 101st

Cong., 2d Sess. 231-32 (1990)]. -

Areas classified at the date of

enactment are not reclassified again by

virtue of the fact that today's notice

reaffirms the designation of those areas

and includes certain nearby locations

within the boundaries of those areas.

The EPA takes the position that because

they are not again classified, they are

not again given the opportunity to make

a 5 percent reclassification, or, in the

case of areas classified serious or

higher, to initiate new efforts to adjust

the boundaries to smaller than the C/

MSA. Interpreting the CAA to allow

such opportunities would be

inconsistent with congressional intent to

expedite the preliminary questions of

designations, classifications, and

boundaries in order to assure that the

heart of the program-the pollution
Federal Register/Vol. 56, No. 215/Wednesday, November 6, 1991/Rules and Regulations

controls themselves-are in place as

quickly as possible [see H.R. No. 101-

490, 101st Cong., 2d Sess., 232 (1990)

(stating that a period of only 90 days is

provided for the 5 percent

reclassification "to assure that State and

EPA resources are devoted to efforts to

attain the standard, and not to changes

in the classification of areas")1.

Although in some cases the

boundaries for an area remained

undetermined until today's notice (i.e.,

areas containing at least some portion

which was attainment at enactment), all

areas ultimately determined to be within

those boundaries and promulgated in

this document are considered to be part

of the nonattainment area designated

and classified at the date of enactment.

As a result, with respect to any

neighboring area that is ultimately

included in the nonattainment area, no

new classification has occurred with

today's notice, and there is no

opportunity for a 5 percent

reclassification or a 45-day C/MSA

process.

The following are specific actions

EPA is taking with respect to

classifications.

Arizona

In a May 15, 1991 letter, Governor

Symington of the State of Arizona

recommended an ozone classification of

transitional for Maricopa County

(Phoenix area) pending verification of

ozone data for calendar year 1990 and

additional studies to be conducted

during 1991 to determine the appropriate

design value. Additional quality-assured

monitoring data for 1990 from two

monitoring sites in Maricopa County

(Papago Park and Vehicle Emissions

Lab) made available since receipt of the

Governor's original recommendation

indicate that a classification of

moderate is more appropriate for the

Phoenix area. Based on this additional,

quality-assured data, EPA is classifying

Phoenix as a moderate area for ozone.

Ohio

On March 15, 1991, the State of Ohio

recommended that Mahoning and

Trumbull Counties be redesignated from

nonattainment to attainment. The EPA

previously disapproved a redesignation

request for this area on July 10, 1990 (see

55 FR 28199). Mahoning and Trumbull

Counties will remain nonattainment

because section 107(a)(4)(A)(iii) does

not permit redesignations to attainment

as part of this general review of

designations and classifications.

Mahoning and Trumbull Counties are

being classified as a marginal ozone

nonattainment area along with Mercer

County, Pennsylvania. There are two

ozone monitors located in this area. One

is located in Youngstown (Mahoning

County, Ohio). This monitor is located in

the urban area of Youngstown and may

not represent the worst-case ozone

concentration in the area. This is due to

the suppression of ozone formation by

NOx in the urban area. The monitor in

Youngstown has not recorded a

violation of the ozone NAAQS based on

1987 through 1989 monitoring data. The

second monitor is located downwind in

Farrell, Pennsylvania (Mercer County,

Pennsylvania). This monitor has

recorded a violation of the ozone

NAAQS based on 1987 through 1989 air

quality data (2.1 average expected

exceedances per year). A violation of

the NAAQS occurs when the average

expected exceedances per year is

greater than 1.0. The monitoring site in

Farrell, Pennsylvania, is approximately

1 to 2 miles to the east of Trumbull

County, Ohio. The EPA has determined

that the monitoring site in Farrell,

Pennsylvania, may have been adversely

impacted by emissions from Mahoning

and Trumbull Counties (see 55 FR 28199,

July 10, 1990). This is based on the

prevailing warm weather (ozone

conductive) winds in the upper midwest.

Since the winds typically blow from the

quadrant bounded by the directions

south and west, the Farrell site is

expected to be downwind on these days.

Based on this information Mahoning and

Trumbull Counties, Ohio, are being

classified, along with Mercer County,

Pennsylvania, as a marginal ozone

nonattainment area with a design value

of .134 ppm.

Pennsylvania

In a March 18, 1991 letter,

Pennsylvania proposed that Lawrence

County be designated "cannot be

classified or better than primary

standa-ds" for ozone. To support its

recommendation, the State pointed out

that ozone NAAQS attainment has been

monitored at a location in that county.

Per section 107(d)(1)(C)(i), an area

designated nonattainment preenactment

of the CAAA of 1990 must be

nonattainment postenactment.

In the same letter, Pennsylvania

proposed that Allegheny County be

designated "cannot be classified or

better than primary standards" for

carbon monoxide. The State bases its

recommendation on the fact that the

county is monitoring attainment. Again,

as Allegheny County was designated

nonattainment prior to passage of the

CAAA, the area remains nonattainment

by operation of law until a carbon

monoxide NAAQS maintenance plan is

developed and approved by EPA. In the

tables section of the 107 classification/

designation notice EPA recognizes the

fact that Allegheny County is not

violating the NAAQS. i.e., that it is

monitoring attainment.

c. Other treatment. With today's

notice, EPA is also promulgating the

affirmed or reaffirmed designations (and

new, affirmed, or reaffirmed boundaries)

of nonattainment area 3 to be treated as

transitional (ozone), submarginal

(ozone), incomplete data (ozone), not

classified(CO), and rural transport

areas (ozone); and codifying its

conclusion that those areas should be

accorded that treatment. These uzeas

are listed in the TSD, item #10.

d. Areas designated entirely

attainment/unclassifiable at enactment

but now subject to redosignation to

nonattainment- i. Serious and higher.

Ohio and West Virginia

As noted in the accompanying tables

of this document, the lsted designation

for the Steubenville, OH-WV

nonattainment area does not reflect EPA

action under section 107(d)(4)(A). At the

date of enactment of the CAAA, the

three counties which make up the

Steubenville MSA-Jefferson County,

Ohio; Brooke County, West Virginia;

and Hancock County, West Virginiawere designated attainment, by

operation of law, under section

107(d](1)(C). The States and EPA are

reviewing whether to confirm or reverse

this present designation under the

process set out under section

107(d)(4](A). The EPA will publish a

separate notice to that effect.

ii. Marginal/moderate. With today's

notice, EPA is promulgating the

designations, classifications, and

boundaries for three areas, Smyth

County, Virginia; Essex County, New

York; and Jefferson County, New York.

These areas were designated entirely

attainment as of the date of enactment;

however, current air quality necessitates

a designation of nonattainment under

section 107(d)(4)(A)(i)-(ii). For new

ozone nonattainment areas, because

they are classified as of the effective

date of today's notice, any

reclassification based on the 5 percent

provision of section 181(a)(3) must occur

within 90 days of that effective date.

The criteria for making the 5 percent

reclassification will be the same as

discussed above. Smyth and Essex

Counties are rural transport areas.

Therefore, a 5 percent downshift is not

applicable to either area.

On March 21, 1991, the Governor of

New York requested a 5 percent

downshift for Jefferson County since its

design value of .143 ppm fell within 5

percent of the marginal classification.

56703
56704 Federal Register/Vol. 56, No. 215/Wednesday, November 0, 1991/Rules and Regulations

Today's notice approves this request

and reclassifies Jefferson County as a

marginal nonattainment area per section

181(a)(4).

Essex County, New York

New York State requested in its

March 21, 1991 letter that Essex County

(non-MSA) be designated attainment.

The State based this request on the fact

that the monitoring station on which the

designation is based is part of an

atmospheric research station on the top

of Whiteface Mountain, and on the

belief that the measurements taken at

this station do not reflect general air

quality in the region. New York State

further commented in a June 4, 1991

letter that the exceedances all occurred

at night when the public could not be

exposed. New York noted that the time

of the exceedances indicate that longrange transport of ozone is the cause of

the violations.

It is EPA's position that the violations

of the ozone NAAQS recorded on

Whiteface Mountain are based on valid

measurements and the State does not

dispute this. However, the fact that the

ozone violations do not originate in

Essex County is not sufficient basis for

designating the area attainment.

Furthermore, the area where the

violations are observed is accessible to

the public. The Whiteface Mountain

area is part of the Lake Placid

recreational area, Adirondack Park, a

year-round resort location. Since the

State's June 4, 1991 letter, additional

exceedances of the ozone standard,

including some day-time readings, have

been recorded at this location.

The EPA does agree that long range

transport appears to be a substantial

contributor to the NAAQS violations on

Whiteface Mountain. Given violations

have occurred only at a higher elevation

while attainment is measured at the

base of Whiteface Mountain, EPA has

determined that a smaller boundary, as

defined by those areas on Whiteface

Mountain above an elevation of 4,500

feet, is more appropriate and a

classification of rural transport

accurately characterizes Whiteface

Mountain (as proposed in an October 4,

1991 letter from New York State to EPA).

The EPA accepts this boundary to

define the nonattainment area on

Whiteface Mountain, allowing the rest

of Essex County to remain attainment.

The EPA believes this boundary

adequately includes the monitor, located

at an elevation of 4,867 feet, and a

reasonable surrounding area.

By selecting 4,500 feet as the

boundary marking the nonattainment

area of Whiteface Mountain, EPA also

believes that the air quality in the

Adirondack Park area, an area

frequented by the public, will benefit by

designating this portion of Essex County

as nonattainment.

The EPA also agrees with the State

that a rural transport status more

accurately reflects the ozone

nonattainment problem in Essex County

at Whiteface Mountain. Documentation

supporting a classification of rural

transport is contained in the TSD, item

#11.

Smyth County, Virginia

In a March 15, 1991 letter to EPA,

Governor Wilder of the Commonwealth

.of Virginia proposed that Smyth County

(non-MSA) remain attainment for ozone.

On May 14, 1991, the EPA opposed

this request and notified the Governor of

Virginia that, while acknowledging

strong evidence of long-range ozone

transport, at least a portion of Smyth

County must be designated

nonattainment.

In a June 3, 1991 letter to EPA Region

III, the State of Virginia recommended

designating the area in Smyth County

above 4,500 feet as nonattainment and

continued to request a classification of

rural transport.

The EPA recognizes the monitored

violations by designating the area in

Smyth County above 4,500 feet elevation

as nonattainment, as recommended by

the State of Virginia in their June 3, 1991

letter to EPA. The EPA accepts this

elevation as a boundary to define the

nonattainment area as EPA believes it

adequately includes the monitor, located

at 5,520 feet, and a reasonable area

surrounding it.

Selecting 4,500 feet as the boundary

marking the nonattainment area of

Smyth County also ensures that the

Appalachian Trail, an area frequented

by the public, is included in the

nonattainment area.

The EPA agrees with the State that a

rural transport status more accurately

reflects the ozone nonattainment

problem in Smyth County.

Documentation supporting Smyth

County as a rural transport area is

contained in the TSD, item #12.

iii. Other treatment. The City of

Oshkosh, attainment for CO prior to

enactment, is hereby designated

unclassifiable for CO. (See the TSD,

item #13, for documentation supporting

this designation.)

9. Procedural requirements. As

described above, today's notice

promulgates designations,

classifications, and boundaries for

ozone and CO areas. This section

describes the procedural requirements

concerning notice- and-comment and

judicial review applicable to these

actions. -

a. Designations and boundaries- i.

Notice-and-comment rulemaking.

Today's notice announces and

promulgates the designations that

occurred under section 107(d)(1)(C)

(designations by operation of law at the

date of enactment of the CAAA) and the

designations (including boundary

determinations) under section 107(d)(4)

(designations submitted by the States

and promulgated by EPA). The EPA

takes this action in accordance with

section 107(d)(2)(A), which requires

publication in the Federal Register of a

notice announcing or promulgating

designations under, among other things,

section 107(d)(1) and (4). Beyond that,

however, section 107(d)(2)(B) provides:

Promulgation or announcement of a

designation under paragraph (1), (4) or (5)

shall not be subject to the provisions of

sections 553 through 557 of title 5 of the

United States Code (relating to notice and

comment), except nothing herein shall be

construed as precluding such public notice

and comment whenever possible.

By its terms, this provision exempts

the designations announced and

promulgated by this notice from the

notice-and-comment procedures under

the Administrative Procedures Act.

Through various publicly available

letters to the States, EPA described its

preliminary views at various points in

time as to the designation and

classification of areas, and interested

persons had the opportunity to give their

views on the subject to EPA. In addition,

the tight timetables Congress set out in

section 107(d)(4)(A)(i)-(ii) made it

difficult to engage in notice-andcomment rulemaking. Therefore, as

permitted under section 107(d)(2)(B),

EPA is today taking final action without

notice-and-comment rulemaking. In

addition, section 307(h), added by the

CAAA provides:

It is the intent of Congress that, consistent

with the policy of the Administrative

Procedures Act, the Administrator in

promulgating any regulation under this Act,

including a regulation subject to a deadline,

shall ensure a reasonable period for public

participation of at least 30 days, except as otherwise expressly proved in section 107[d),

172(a), 181(a) and (b), and 186(a) and (b).

The EPA is interested, however, in the

public's views on whether EPA has

made significant errors which could

have been avoided had notice-andcomment rulemaking been possible.

Accordingly, EPA will allow 30 days

from the date of this document for public

comment on any such errors, and, if

such errors are brought to EPA's

attention, EPA will correct any technical
Federal Register/Vol. 56, No. 215/Wednesday, November 6, 1991/Rules and Regulations

errors made. In addition, if anyone

raises significant new policy issues, EPA

will pursue notice-and-comment

rulemaking to resolve such issues. This

notice will take effect 60 days from the

date of publication, except to the extent,

if any, that EPA determines corrections

are necessary in light of errors

elucidated by timely public comment.-

ii. Judicial review. The CAAA provide

no additional limits on judicial review of

the designations, including boundaries.

Accordingly, if a party follows the

appropriate administrative procedures

under CAAA, section 307, the party is

not barred from challenging EPA's

action in this regard through litigation. - b. Classifications- i. Notice and

comment. Sections 181(a)(3) and

186(a)(2) provide that at the time EPA

publishes the notice designating ozone

and CO nonattainment areas:

The Administrator shall publish a notice

announcing the classification of [such ozone

or CO1 nonattainment area. The provisions of

section 172(a)(1](B) (relating to lack of notice

and comment and judicial review) shall apply

to such classification.

Section 172(a)(1), which is found in

subpart I of part D, deals primarily with

classifications that EPA may make upon

promulgating a new or revised NAAQS

and designating areas in accordance

with that new or revised NAAQS.

Section 172(a)(1)(A) authorizes EPA to

make classifications; section

172(a)(1)(B), which is referenced by

sections 181(a)(3) and section 186(a)(2).

provides, in relevant part: -

The Administrator shall publish a notice in

the Federal Register announcing each

classification under subparagraph (A), except the Administrator shall provide an

opportunity of at least 30 days for written

comment. Such classification shall not be

subject to the provisions of sections 553

through 557 of title 5 of the United States

Code (concerning notice and comment) and

shall not be subject to judicial review until

[specified times).

The EPA interprets the reference in

sections 181(a)(3) and 186(a)(2) to "[tihe

provisions of section 172(a)(1)(B)

(relating to lack of notice and comment

and judicial review)" to refer to the

second sentence in section 172(a)(1)(B),

not the first sentence. As a result, the

provisions of the first sentence requiring

a 30-day comment period do not apply

to the classifications under section

181(a)(3) or section 186(a)(2), which are

the subject of this document. The EPA

interprets the parenthetical phrase in

sections 181(a)(3) and 186(a)(2) to limit

the applicable provisions of section

172(a)(1)(B) to those that eliminate the

notice-and-comment requirement, which

are found in the second sentence. This

reading is consistent with the fact that

the first sentence in section 172(a)(1)(B)

sets out the requirement for publishing a

notice announcing a classification, a

requirement that is separately

incorporated in sections 181(a)(3) and

186(a)(2). This duplication suggests that

the first sentence of section 172(a)(1)(B)

does not apply.

Similarly, EPA takes the position that

notice-and-comment rulemaking is not

required for any decisions by EPA under

section 181(a)(4) or section 186{a)(3) to

make, or not to make, reclassifications

on the grounds that the air quality of an

ozone or CO nonattainment area is

within 5 percent of the cut-off for a

different classification. Sections

181(a)(4) and 186(a)(3) provide that EPA

is to make these decisions "by the

procedure required under paragraph

[section 181(a)1(3)" for ozone, or "by the

procedure required under paragraph

[section 186(a)(2)1" for CO. As just

discussed, those procedures eliminate

the requirement for notice-and-comment

rulemaking. -

ii. Judicial review. As noted above,

sections 181(a)(3) and 186(a)(2) provide

that the provisions concerning judicial

review found in section 172(a)(1)(B)

apply. Those provisions state that

judicial review may occur only after.

[Tihe Administrator takes final action

under subsection (k) or (1) of section 110

(concerning action on plan submissions) or section 179 (concerning sanctions) with

respect to any plan submissions required by

virtue of such classification.

Accordingly, judicial review on the

classification decisions [(including the

decisions to make, or not to make,

reclassifications under the 5 percent

adjustment provisions of section

181(a)(4) and section 186(a)(3)] may be

had only at those times.

B. PM-10

1. Initial PM-10 designations.

Previously, EPA published a Federal

Register notice announcing the

designations and classifications for PM10 occurring by operation of law upon

enactment of the CAAA (see 56 FR

11101, March 15, 1991). In addition, EPA

has published a follow-up notice

correcting the boundaries and

designations of some areas in light of

comments addressing the March 1991

notice (see 56 FR 37654, August 8, 1991).

Both of these notices provide a detailed

discussion of the history and current

status of PM-10 areas nationwide. An

abbreviated discussion is provided here.

Generally, EPA adopted a PM-10 SIP

development policy "grouping" all areas

of the country into three categories

based on their probability of violating

the standards when EPA revised the

indicator for particulate matter to PM-lu

(see generally 52 FR 24634, July 1, 1987)

(revising particulate matter indicator

from total suspended particulates to

PM-10}. The EPA announced the initial

groupings for PM-10 in a Federal

Register notice published on August 7,

1987 (52 FR 29383). The EPA modified

the groupings and boundaries in two

subsequent Federal Register notices

published on March 28, 1989 (54 FR

12620) and October 31, 1990 (55 FR

45799).

The CAAA provided designations for

PM-10 for the first time, using EPA's

grouping scheme as a starting point.

Specifically, the amended law provides

that each former Group I area identified

in 52 FR 29383 (August 7, 1987), except to

the extent modified before enactment of

the CAAA (November 15, 1990), was

designated nonattainment for PM-10

[see 107(d)(4)(B)(i) of the amended Act].

The Federal Register notice published

on October 31, 1990 (55 FR 45799)

clarified or "modified" EPA's

identification of the Group I areas listed

in the August 1987 notice. Thus, as a

general matter, the former Group I areas

listed in the October 1990 notice became

nonattainment for PM-10 by operation

of law upon enactment of the CAAA

[the October 31, 1990 notice reflects the

revisions announced in the notice

published on March 28, 1989 (54 FR

12620)]. Any other area (i.e.. Group 11 or

11) violating the PM-10 NAAQS (as

determined by 40 CFR part 50, Appendix

K) prior to January 1, 1989, also was

designated nonattainment for PM-10 by

operation of law upon enactment of the

CAAA [see section 107(d)(4)[B)(ii) of the

amended ActI. All other areas were

designated unclassifiable for PM-10 by

operation of law upon enactment of the

CAAA [see section 107(d)(4)(B](iii) of

the CAAA]. Finally, all of those areas

designated nonattainment for PM-10

were classified as moderate by

operation of law at the time of the

designation [see section 188(a) of the

CAAA). The EPA will be reclassifying

some of these initial PM-10

nonattainment areas from moderate to

serious if EPA determines they cannot

practicably attain the PM-10 air quality

standards by December 31, 1994 [see

section 188(b)(1)].

In the Federal Register notices

published on March 15, 1991 (56 FR

11101) and August 8, 1.991 (56 FR 37654)

the EPA applied sections 107(d)(4)(B)

and 188(a), and other operative legal

provisions, and announced the

designations and classifications for PM10. In today's notice, EPA formally

codifies the designations and

classifications for PM-10 announced in

these prior two notices. Further, in a

5 670M5
56706 Federal Register/Vol. 56, No. 215/Wednesday, November 6, 1991/Rules and Regulations

letter dated October 2, 1991, Governor

Stephens of the State of Montana

informed EPA that the August 8, 1991

corrections notice contained an editorial

error in the boundary for Libby,

Montana. The EPA has reviewed the

Governor's letter and the boundary for

Libby. The EPA concurs with the

Governor's comment and has corrected

the boundary for Libby. Thus, the

codification of the initial designations and classifications for PM-10 are as set

forth in the table below. Note that

today's codification of the initial

designations for PM-10 [under section

107(d)(4)(B)] in 40 CFR part 81

represents final agency action for the

purpose of section 307(b) of the CAA.

2. Additional PM-10 designations. As

discussed above, all areas of the c:ountry

were designated either nonattainment or

unclassifiable for PM-10 by operation of

law upon enactment of the CAAA

pursuant to section 107(d)(4)(B). Section

107(d)(3) of the CAAA authorizes the

Administrator to redesignate as

nonattainment those areas initially designated as unclassifiable for PM-10

[see section 107(d)(3)(A), (B), and (C)].

The EPA has initiated the redesignation

process for some areas. Specifically, in

January and February of 1991, EPA

Regional Administrators provided

letters to the Nation's Governors

initiating the process of redesignating

additional areas as nonattainment for

PM-10, as called for in section

107(d)(3)(A) of the CAAA. In addition, in

a Federal Register notice published on

April 22, 1991 (50 FR 16274), the EPA

identified those PM-10 areas for which

EPA had notified the Governors of

affected States that an area's PM-10

designation should be revised to

nonattainment. (The need to revise the

designation for the section in LaSalle

County, Illinois, that EPA had identified

in the April 22, 1991 notice has been

rendered moot. In the correction notice

for the initial nonattainment areas

published in the Federal Register of

August 8, 1991 (56 FR 37654), EPA

indicated that this section was

designated nonattainment and included

as part of the initial Oglesby, Illinois,

PM-10 nonattainment area.)

In a separate Federal Register notice,

EPA will propose redesignations for

these areas in light of comments

received from the affected States. A

more detailed discussion about the

section 107(d)(3) redesignation process and the actions being proposed will be

described in that notice. [Note that the

section 107(d)(3) redesignation process is different from the section 107(d)(4)(B)

designations occurring by operation of

law upon enactment of the CAAA in

that the section 107(d)(3) redesignations

are not exempt from the notice-andcomment rulemaking procedures of the

Administrative Procedures Act (section

107(d)(2)(B) of the CAAA).]

As mentioned, EPA Regional

Administrators have corresponded with

some of the Nation's Governors,

initiating the process to redesignate

additional areas of the country as

nonattainment for PM-10. In some of the

responses to these letters, States

requested that EPA expand the

boundaries of former Group I areas and

make the expansion area part of an

initial nonattainment area. In the

situations where EPA believed there

was no legal basis to make such an

adjustment, EPA has indicated that it

would treat the State's request as an

unsolicited request to redesignate the

additional area as nonattainment within

the meaning of section 107(d)(3)(D) of

the CAAA (56 FR 37654, August 8, 1991).

Accordingly, in a separate Federal

Register notice, EPA will determine

whether such submittals are complete

and, if so, will propose to approve or

deny the State's redesignations request

[see section 107(d)(3)(D) of the CAAA].

3. Total suspended particulates (TSP).

Section 107(d)(4)(B) of the CAAA

provides that the designations for

particulate matter measured in terms of

TSP existing immediately prior to

enactment of the CAAA (November 15, 1990) remain in effect. The TSP

designations are to remain in effect until

the Administrator determines that the

designations are no longer necessary for

implementing the maximum allowable

increases in concentrations of

particulate matter, measured in terms of

TSP, pursuant to section 163(b) [section

107(d)(4)(Bfl.

Thus, by this notice, EPA announces

that the TSP designations existing before enactment of the CAAA shall

remain in effect for now. Further, EPA

notes that it will review the need for

these designations and provide notice at

such time EPA determines these

designations are no longer necessary for

the purpose of implementing the

increments in section 163(b).

C. Sulfur Dioxide (SO2)

1. Initial S02 designations. Section

107(d)(1)(C) of the CAAA generally

provides that those SO2 designations

existing before enactment of the CAAA were affirmed at enactment by

operation of law. Thus, the designation

of an SO2 area existing just prior to

enactment of the CAAA (November 15,

1990) become the designation of the area

upon enactment and at this time. To

avoid unnecessary duplication, EPA will

not reprint the codification table for SO2

in today's notice. For the status of SO2

areas, readers should refer to the

codification tables currently set forth in

40 CFR part 81 (July 1, 1991) and to any

subsequent modifications to these SO2

tables that have been published in the

Federal Register.

2. Additional S02 designations. As

with the additional PM-10

nonattainment areas, EPA has initiated

the redesignation of some S0 2 areas

pursuant to section 107(d)(3) Qf the

CAAA [section 107(d)(3)(A), (B), and

(C)]. In January and February of 1991,

EPA Regional Administrators provided

letters to the Nation's Governors

initiating the process of redesignating

additional areas as nonattainment for

SO2, as called for in section 107(d)(3)(A-)

of the CAAA. In addition, in a Federal

Register notice published on April 22,

1991 (56 FR 16274), EPA identified those

SO2 areas for which EPA had notified

the Governors of affected States that an

area's S02 designation should be

revised to nonattainment.

In a separate Federal Register, EPA

will propose designations for these

areas in light of comments received from

the affected States. A more detailed

discussion about the section 107(d)(3)

redesignation process and the actions

being proposed for particular areas will

be described in that notice.

D. Lead

1. Background. In 1978, when EPA

promulgated the lead NAAQS, the

Agency believed that implementation

and maintenance of the lead NAAQS

should be in accordance with the SIP

requirements set forth in section 110 of

the CAA and not Part D. Therefore, EPA

did not designate areas for lead. The

Agency believed that section 107 and

the Part D requirementswere intended

by Congress to apply only to NAAQS

which were set prior to 1977. The CAA,

as recently amended in 1990, clearly

authorizes EPA to designate areas for

the lead standard in effect at the date of

enactment of the CAAA. Once an area

is designated nonattainment for the lead

standard in effect at the date of

enactment, the SIP requirements for the

area are as set forth in sections 191 and

192 of the CAAA.

Section 107(d)(5) of the CAAA

authorizes EPA to require States to

designate areas (or portions thereof) as

nonattainment, attainment or

unclassifiable with respect to the lead

NAAQS in effect as of the date of

enactment of the CAAA. As provided in

section 107(d)(5), these lead areas are to

be designated pursuant to the

procedures outlined in section

107(d)(1)(A) and'(B) of the amended
Federal Register/Vol. 56, No. 215/Wednesday, November 6, 1991/Rules and Regulations

CAAA except that certain timeframes in

subparagraph (B) have been modified by

section 107(d)(5).

Section 107(d)(1)(A) of the amended

CAAA permits EPA to require the

Governors of affected States to submit

their recommended designations for the

areas EPA seeks designated in a

timeframe that EPA deems reasonable.

This timeframe, however, can be no

sooner than 120 days, nor later than 1

year, after the date EPA notifies the

State of the requirement to submit such

designations. Section 107(d)(1)(B) of the

CAAA requires EPA to promulgate these

designations no later than 1 year after

notifying the State of the requirement to

designate areas for lead. The EPA may

make any modifications deemed

necessary to the suggested designations

submitted by the State [see generally.

section 107(d)(1)(B) of the CAAA].

However, no later than 120 days before

promulgating a modified area, EPA must

notify the affected State and provide an

opportunity for the State to demonstrate

'why any proposed modification is

inappropriate. If the Governor of an

affected State fails to submit the

required lead designations, in whole or

in part, EPA is required to promulgate

the designation that is deemed

appropriate for any area (or portion

thereof) not designated by the State.

In January and February 1991, EPA

notified the Governors of affected States

that they should proceed to designate as

nonattainment those areas that had

recorded violations of the lead NAAQS.

In addition, EPA has requested the

Governors to designate as unclassifiable

those areas that contain stationary lead

sources which EPA believes to be .

capable of violating the lead NAAQS,

but for which existing air quality data

are insufficient at this time to designate

as attainment or nonattainment [section

107(d)(1)(A)(iii)]. For administrative

efficiency reasons, in the January and

February letters, EPA requested the

States to submit the designations by

March 15, 1991 [the date the lists of

designations for all ozone and CO areas

were due from the Governor of each

State pursuant to section 107(d)(4)(A) of

the CAAA]. In any event, EPA indicated

to the States that they had to submit

their designations not later than 120

days from the date EPA notified them of

the requirement to submit such

designations. In a Federal Register

notice published on April 22, 1991 (56 FR

16274), EPA identified those areas for

which EPA had requested designations

for lead.

The designation requests submitted

by the Governors have created several

different situations which require that

EPA act on the designations in several

actions. The EPA has termed the EPArequested designations submitted by

Governors as "solicited designations"

and the designations submitted by

Governors on his/her own initiative as "unsolicited designations." The different

situations and when EPA intends to

formally act on the designations are as

follows:

(1) Solicited designation requests

submitted within a timeframe sufficient

enough for EPA to review and process,

and which EPA does not intend to

modify, are addressed in this document.

(2) Solicited designation requests

which EPA intends to modify will be

addressed at a later date. (As mentioned

earlier, EPA must notify the affected

State 120 days prior to the promulgation

of a modified area and provide an

opportunity for the State to demonstrate

why any proposed modification is

inappropriate. The EPA notified affected

States in May 1991.)

(3) Unsolicited designation requests

which EPA may or may not modify will

be addressed at a later date. (Although

the affected Governors have been

notified within the required timeframes

that EPA intends to modify the

designation submittal, EPA has decided

that in order to provide adequate time

for the affected Governors to respond

and for EPA to review any response, it

would be more appropriate to address

the unsolicited designation requests in a

separate notice.)

2. Today's action. In today's notice,

EPA is acting on those State submittals

which were received by EPA in a

timeframe sufficient enough to review

and process, and which EPA does not

intend to modify. The EPA is publishing

these designations as called for in

section 107(d)(2)(A) of the CAAA. The

States affected by this notice include:

Alabama, Florida, Georgia, Indiana,

Louisiana, Minnesota, Missouri,

Montana, Nebraska, New York, Ohio,

Tennessee, and Texas. The States of

Montana, New York, and Texas

submitted both solicited and unsolicited

designation requests. In this notice, EPA

is acting only on the solicited portion of

the submittals for which EPA has

-determined modifications are not

necessary. The unsolicited portion of the

submittal will be addressed in a

separate notice.

A brief description of the

nonattainment and unclassifiable lead

areas is provided below. The legally

binding description of the nonattainment

and unclassifiable area lead boundaries

for each affected State is provided in the

rulemaking tables at the end of this

document.

A lead nonattainment area consists of

that area which does not meet (or that

contributes to ambient air quality in a

nearby area that does not meet) the lead

NAAQS [see section 107(d)(1)(A)(i)]. A

lead unclassifiable area consists of any

area that cannot be classified on the

basis of available information as

meeting or not meeting the lead NAAQS

[see section 107(d)(1)(A)(iii)]. Generally,

EPA has recommended that the lead

nonattainment and unclassifiable

boundaries be defined by the county

perimeter for the county in which the

ambient lead monitor(s) recording the

violation of the lead NAAQS and/or the

lead source is located. In some

situations, however, a boundary other

than the county perimeter may be

appropriate. States may seek to

alternatively define the lead

nonattainment or unclassifiable

boundary by using one, or a

combination, of the following

techniques: (1) Qualitative analysis: (2)

spatial interpolation of air monitoring

data, or (3) air quality simulation by

dispersion modeling. The techniques are

described:in more detail in "Procedures

for Estimating Probability of

Nonattainment of a PM-10 NAAQS

Using Total Suspended Particulate or

PM-10 Data," EPA-450/4-86-017,

December 1986. If a State seeks to

alternatively define a lead

nonattainment area, EPA recommends

that it submit a reasoned and

documented justification for the

boundary identified.

Finally, the air quality monitoring data

and other technical information

supporting today's action are available

from the respective EPA Regional Office

which serves the State where the

affected area is located. The addresses

of the Regional Offices are listed in the

addresses section of this document.

As noted, this action is being taken

pursuant to section 107(d)(5) of the

CAAA. As with the section 107(d)(4)

designations for ozone and CO areas,

the designations under section 107(d)(5)

are exempt from the Administrative

Procedures Act requirements for noticeand-comment rulemaking (5 U.S.C.

sections 553-557) [see section

107(d)(2)(B) of the CAAA]. Nevertheless,

as with the ozone and CO designations in today's notice, EPA will entertain any

comments on these actions that are

received by December 6, 1991, for the

purpose of correcting technical errors.

The EPA's promulgation of these

designations [for purposes of section

107(d)(2)(A)] will become effective on

January 6, 1992. This is intended to

provide EPA with time to make any

technical corrections that are

appropriate in light of the comments.

3. Additional actions. The EPA

intends to modify some of the suggested

designations submitted by States in

response to EPA's request to designate

areas for lead. As called for in section

107(d)(1)(B)(ii), EPA has notified the

affected States that EPA believes

modification is necessary and is

providing them with an opportunity to

demonstrate why EPA's proposed

modification is inappropriate. The EPA

will address the modified designations

to the solicited submittals in a separate

Federal Register notice, to be published

in the near future.

Additionally, EPA has received

unsolicited lead designation requests

from some States. At this time, EPA

intends to modify most of these requests

and, accordingly, has notified the

affected States and is providing them

with an opportunity to demonstrate why

EPA's proposed modification is

inappropriate. The EPA also will

address these unsolicited designations

in a separate Federal Register notice, to

be published in the near future.

4. Miscellaneous. The EPA will

continue to assess ambient monitoring

data as they are received. Areas that

record violations of the lead NAAQS

will be reviewed. If EPA determines that

a nonattainment designation for an area

is appropriate, EPA will so inform the

Governor of the affected State and

require the Governor to submit a

designation request [section 107(d)[5) of

the CAAA and cross reference to

section 107(d)[1)].

Additionally, section 107(d)(1)(A) of

the CAAA authorizes Governors to

submit, at any time the Governor deems

appropriate, a list of areas designated as

nonattainment, attainment, or

unclassifiable for lead. Section

107(d)(1)(B)(iii) of the CAAA requires

that EPA must then act on these

designation requests in accordance with

the procedures in section 107(d)(3).

III. Tables

The tables codified in today's action

are significantly different from the

tables now included in 40 CFR part 81.

The current 40 CFR part 81 designation

listings (revised as of July 1, 1990)

include by State and NAAQS pollutant, a brief description of areas within the

State and their respective designation.

The EPA has modified this format in

order to better describe the areas and

their attainment status and to account

for the pollutant classifications required

by the CAAA. Today's action includes

completely new tables for ozone and

CO. The SO2 , NO 2, and TSP tables are

not modified by today's action but will

in the future be revised, as appropriate,

to this new format. Lead tables include

the areas currently designated as

nonattainment and unclassifiable. The

PM-10 tables identify those areas

currently designated as nonattainment

for PM-10. As provided in section

107(d)(4)(B) of the CAAA, all of those

areas in a State not designated

nonattainment for PM-10 were

designated unclassifiable for PM-10.

The tables do not specify the PM-10

unclassifiable areas but by implication

all those areas not currently designated

nonattainment for PM-10 are designated

unclassifiable.

IV. Other Regulatory Requirements

A. Executive Order 12291

Under E.O. 12291, EPA is required to

judge whether an action is "major" and

therefore subject to the requirement of a

regulatory impact analysis. The Agency

has determined that the attainment,

nonattainment, and classified area

designations and classifications made

final today would result in none of the

significant adverse economic effects set

forth in section 1(b) of the E.O. as

grounds for a finding that an action is "major." The Agency has, therefore,

concluded that this action is not a "major" action under E.O. 12291. This

rule was submitted to the Office of

Management and Budget (OMB) for

review under this E.O.

A copy of the draft rule as submitted

to the OMB, any documents

accompanying the draft, any written

comments received from other agencies

(including OMB), and any written
Federal Register/Vol. 56, No. 215/Wednesday, November 6, 1991/Rules and Regulations

responses to these comments have been

included in the Docket.

B. Regulatory Flexibility Act

Whenever an agency is required by

law to publish a general notice of

proposed rulemaking, the Regulatory

Flexibility Act of 1980 (5 U.S.C. 601-612)

generally requires that the agency

prepare a Regulatory Flexibility

Analysis describing the impact of the

proposed rule on small entities. Because

this rule is not required to be published

first as a notice of proposed rulemaking

under section 553 (the Administrative

Procedures Act) or any other law, it is

not subject to the requirements of the

Regulatory Flexibility Act.

List of Subjects in 40 CFR Part 81

Air pollution control, National parks,

Wilderness areas.

Dated: October 28,1991.

William K. Reilly,

Administrator.

Therefore, 40 CFR part 81 is amended

as follows:

1. The authority citation for part 81 is

revised to read as follows:

Authority: 42 U.S.C. 7407, 7501-7515, 7601.

2. Section 81.300 is revised to read as

follows:

§ 81.300 Scope.

(a) Attainment status designations as

approved or designated by the

Environmental Protection Agency (EPA)

pursuant to section 107 of the Act are

listed in this subpart. Area designations

are subject to revision whenever

sufficient data becomes available to

warrant a redesignation. Both the State

and EPA can initiate changes to these

designations, but any State

redesignation must be submitted to EPA

for concurrence. The EPA has replaced

the national ambient air quality

standards for particulate matter

measured as total suspended particulate

(TSP) with standards measured as

particulate matter with an aerodynamic

diameter less than or equal to a nominal

10 micrometers (PM-A10). Accordingly,

area designations for PM-10 are

included in the lists in subpart C of this

part. However, the TSP area

designations will also remain in effect

until the Administrator determines that

the designations are no longer necessary

for implementing the maximum

allowable increases in concentrations of

particulate matter pursuant to section

163(b) of the Act, as explained in

paragraph (b) of this section.

(b) Designated areas which are listed

below as attainment ("Better than

national standards") or unclassifiable

("Cannot be classified") for total

suspended particulate (TSP), sulfur

dioxide (SO2), and nitrogen dioxide

(NO2), represent potential baseline

areas or portions of baseline areas

which are used in determining

compliance with maximum allowable

increases (increments) in concentrations

of the respective pollutants for the

prevention of significant deterioration of

air quality (PSD). With respect to areas

identified as "Rest of State" it should be

assumed that such reference comprises

a single area designation for PSD

baseline area purposes. However, for

PM-10, the use of the term "Rest of

State" is an interim measure to

designate as unclassifiable all locations

not originally designated nonattainment

for PM-10 in accordance with section

107(d)(4)(B) of the Act.

(c) For PM-10 areas designated

nonattainment, pursuant to section

107(d)(4)(b) by operation of law upon

enactment of the 1990 Amendments to

the Act, the boundaries are more fully

described as follows:

(1) For cities and towns, the boundary

of the nonattainment area is defined by

the municipal boundary limits as of

November 15, 1990, the date the 1990

Amendments were signed into law,

except for areas which were formerly

categorized as "Group I areas", in which

case the nonattainment area is defined

by the municipal boundary limits as of

October 31.1990.

(2) Similarly, for planning areas, air

quality maintenance areas, air basins,

and urban growth boundaries the

nonattainment area is defined by the

entire planning area, air quality

maintenance area, air basin, or urban

growth boundary as of November 15,

1990, except for areas which were

formerly "Group I", in which case the

boundary is defined by the entire

planning area, air quality maintenance

area, air basin, or urban growth

boundary as of October 31, 1990. The

foregoing is true except to the extent the

planning area, air quality maintenance

area, air basin, or urban growth

boundary is further defined, e.g., by

township, range and/or section. Such

geographical descriptors remain a fixed

part of the nonattainment boundaries

irrespective of whether they are

included in the planning area, air quality

maintenance area, air basin, or urban

growth boundary.

(3) The boundaries of PM-10 areas

subsequently redesignated pursuant to

section 107(d)(3) of the Act will be

defined by the city, town, planning area,

air quality maintenance area, air basin,

or urban growth boundary in effect the

date the designation is promulgated.

3. Section 81.301 is amended by

revising the tables for "Alabama-O"

and "Alabama-CO", and by adding a

new table titled "Alabama-Lead" to be

inserted in alphabetical order

immediately following the tabular entry

for "Alabama-SO." to read as follows:
