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 nomina110 

micrometers (PM-10), and lead in 

accordance with the requirements of the 

Clean Air Act (CAA). 

B. Preeanctment Status and Clean Air 

Act Amendmenls (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. 

1'he 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, SOz, 

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, 

makirtg 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, follcwed up the 

November 15, 19901etter 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 Re€;ional 

Administrator providinq more detailed 

information on determining 

designations, classifications, and 

boundaries; notificatiori of SIP 

deficiencies; and inforniation 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 canie 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 

SOa. PM-10, and lead nonattainment 

areas, including boundary 

recommendations. Statt:s were 

encouraged to provide at this time the 

additional boundary studies and 

recommendations for the serious, 

severe, and extreme ozune and CO 

areas covered by the 45-day letters. By 
56696 Federal Register/Vol. 56, No. 215/Wednesday, November .6, 1991/Rules and Regu)ations 

May 14, 1991 (180 days a£ter enactment), 

EPA Regional Administrators ciotified 

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 

fullowing 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 SOz , 

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 pocket 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 pocket 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 

l. lntroduction. 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. Enactmenl—a. Designations/ - 

boundaries/classi fic a tions—i. 

Designations. As described in this 

section, at the date of enaGtment, 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 aiea 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. 

iii. Clvssificalions/other.treatments— 

(a) General. –As described in .this 

section, all ereas (with 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(a)(1) provides: 

Each area designated nor.attainment for 

ozone pursuant to section 107(d) 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 nonattainment 

prior to enactment occurred at the same 

time that those areas were designated 

by operation of law as nonattainment 

under section 107(d)(1)(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(d)(4)(A)(ii). 

For ozone, classification is to be 

based on the following table of design 

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

lerea classification I ~

ign value ( rts per 

miliion~ 

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

including) 0.138 

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

inciuding) 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-1 .......................... 9.1-12.7 

Moderate-2 .......................... 12.8-16.4 
Federal Register/Vol. 56, No. 215/Wednesday, November 6, 1991/Rules and Regulations 56697 

Area ctassficatlon Oesign value (ppm). 

Serfous ............................... 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 

,iesignate 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)Submatginal. 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 EPiA'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 as nonattainment prior to 

enactment of the CAAA), which "has 

not violated the [NAAQS]" 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 "Incornplete 

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 jozone). 

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 niake 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 
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 -F 45 days: C/MSA 

boundar.yprocessbegins 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 thefr 

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: 5 percent 

classification adjustment—a. General. 

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

an ozone or CO nonattainment aiea 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, 

vvhich 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 classifir,ation 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 

primari.lyapplicable 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 a.ir 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. I-Iowever, 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 at.tainment. 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 56699 

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 unclassif[able 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 pocket 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 + IBO days: EPA 

lzotifies States of intent to modify 

suggested designations for certain 

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

(1)(13)(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.Enaclment - - 200 days: Slates 

respond to EPA's proposed 

modifications. Consistent with section 

307(d)(4)(A)(ii) and (1)(13)(ii), EPA 

provided the affected States with an 

opportunity to demonstrate why any of 

EPA's proposed modifications were 

inappropriate. The F.PA 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 -t- 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 

nonattainnient 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 Covernor 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-tVew BritainMiddletown CMSA, the Waterbury, CT, 

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

MSA, and the New HavE:n-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 srnaller than the C/MSA. For these 

areas, the portions of the C/MSA not 

included in the noinattainment area 
56700 t:'ederal Register/Vol. 58, 1Vo. 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 CrMSA 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 vioiations 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. 

i.os 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, 638 F.2d 323, 380-81, 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 y.ield 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 determtnations.) 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, IIrPortions 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 changesbe 

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 CJ 

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 await,ing the State's studies. The final 

determinations will be promulgated in a 

separate Federal Register notice. 

b. Ozone ond CO areas designated 

nonattainment at date of enactment— 

classified mar,ginal ormoderate—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 requirPrnents. – 

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

EPA to promulgate a designation of 

"nonattainment" for an area. Section 

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

area as— 

any area that does not meet (or that 

contributes to ambient air quality in a nearby 

area that does not meet) the [NAAQS). 

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 56701 

authorizes EPA to make "such 

modifications as the Administrator 

deems necessary to the designations of 

the areas (or portions thereof) ` ` ` 

(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 307(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 

notic: 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 [NAAQS)." 

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 aurrounding 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 nonattainnient and in 

which sources likely to contribute to the 

nonattainment problem are located. 

South Carolina 

The Cowpens monitor in the 

northwest corner 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 
56702 Feaeral Register/VoJ. 56, 1Vo. 215/Wednesday, No vember B, 1991/Rulesand 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 beiieves 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 ievels. 

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 Manhat,tan. 

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 

classificataon (high moderate) as the 

CMSA, which includes northern New 

Jersey. 

Tennessee 

On March 12, 1991, (,overnor 

McWherter and Coinmissioner Luna 

submitted the recommendation that the 

City of Mempbis 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 

difficuit 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 proposai 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 aocompanying 

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)(A)(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 thesa 

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 nonattaanment area:' This 

designation occurred at the date of 

enactment. - 

The fact that alassification 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 95-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 "{w]ithin 90 days of 

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

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

Areas classif ed 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 ssrious or 

higher, to initiate new efforts to acljust 

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, Novembe r 6, 1991/Rules and Regulations 56703 

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. 

Althuugh in some cases the 

L-oundaries 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 

r.eighberfng 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. 

Arizorto 

In a May 15, 1991 letter, Governor 

Symington of the State of Arizona 

recommended an ozone classification of 

transitionaI 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 

I.ab) 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 

r.ot 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 viotation 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 Trtimbull 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 ir.formation 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 

standai•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 treatrnent. With today's 

notice, EPA is also promulgating the 

affirmed or reaffirmed designations (and 

new, affirmed, or reaffirmed boundariEs) 

of nonattainment area3 to be treated as 

transitiona) (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 ureas 

are listed in the TSD, item #10. 

d. Areas designated entirely 

attainment/unclassifiable at enactment 

but now subject to redesignation to 

nonattainmenl— i. Serious and hiSher. 

Ohio and 14,1est Virginia 

As noted in the accompanying tables 

of this document, the listed 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 Virginia— 

were 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 wilt publish a 

separate notice to that effect. . 

ii. Marginal/moderate. With today's 

notice, EPA is promulgating the 

designations, classificaitions, and 

boundaries for three areas, Smyth 

County, Virginia; Essex County, New 

York; and Jefferson County, New York. 

These areas were designated entirety 

attainment as of the date of enactment; 

however, current air qaality 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 

reclassiflcation based on the 5 percent 

provision of section 181(a)(3) riiust 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 sinoe its 

design value of .143 ppm fell within 5 

percent of the marginal classification. 
56704 Federal Register/Vol. 56, No. 215/Wednesday, Nove:nber G, 1991/Rules and Regu lations 

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 21,19911etter that Essex County 

(non-MSA) be designated attalnment. 

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 vio)ations 

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 4,19911etter, 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 4,887 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. Doeumentation 

supporting a classification of rural 

transport is contained in the TSD, item 

#11. 

Smyth County, Virgirua 

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 

v,iolations 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. Designotions and boundaries— i. 

Notice-and-comment rulemoking. 

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 188(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 56:05 

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 chal)enging EPA's - 

action in this regard through litigation. - 

b. Classlficatfons— I. Notice and 

commenG Sections 181(a)(3) and 

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

publishes the notice designating ozone 

and CO nonattainment areas: 

Ttie Administrator shall publish a notice 

announcing the classification of [such ozone 

or CO] nonattainment area. The provisiona 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 1 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 provisipns of sections 553 

through 557 of title 5 of the United States 

Code (conceming 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 "[t)he 

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 pravisions 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 clEssification, 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 

ru)emaking. — 

ii. Judiclal 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 oecur only after: 

[T)he 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 on(y at those times. 

B. PM-10 

1. Inilial PM-10 deslgnations. 

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 37854, 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-10 

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

(revising particulate matter indicator 

from tota1 suspended pa.rticulates 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 bouiidaries in iwo 

subsequent Federal Register nolices 

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 Z8,1989 (54 FR 

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

1I1) 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 Act]. All other areas were 

designated unclassifiable for PM-10 by 

operation of (aw upon enactment of the 

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

the CAAAJ. Finally, all of those areas 

designated nonattainrr.ent 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 8,1991 (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 
56706 Federal Register/Vol. 56, 1Vo. 215/Wednesday, Nocember 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 country 

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 (58 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 (7'SPj. 

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)(13)]• 

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 (SOz) . 

l. lnitial S02designations. Section 

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

provides that those SOs designations 

existing before enactment of the CAAA 

were affirmed at enactment by 

operation of law. Thus, the designation 

of an SO, 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 SOa 

in today's notice. For the status of SOz 

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 SOz 

tables that have been published in the 

Federal Register. 

2. Additional SOs deslgnations. As 

with the additional PM-10 

nonattainment areas, EPA has initiated 

the redesignation of some S02 areas 

pursuant to section 107(d)(3) pf 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 

S02, as called for in section 107(d)(3)(Ar 

of the CAAA. In addition, in a Federal 

Register notice published on Apri122, 

1991 (56 FR 16274), EPA identified those 

S02 areas for which EPA had notified 

the Governors of affected States that an 

area's SOz 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 requirements were 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 ere 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, Navember 6, 1991/Rules and Regulations 56707 

CAAA except that certain timeframes in 

subparagraph (B) have been modified by 

section 307(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. 

'I'his 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 ' 

r.ecessary 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 

designafions. 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 

c'ifferer.t situations which require that 

EPA act on the designations in several 

action3. The EPA has termed the EPArequested designations submitted by 

Governors as "soL'cited designations" 

and the designations submitted by 

C•overnors 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 actlon. 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 

r.ecessary. The unsolicited portion of the 

subniittal will be addressed in a 

separate notice. 

A brief description of the 

nonattainment and unclassifiable lead 

a: eas is provided below. The legally 

binding description of the nonattainment 

and unclassiCiable 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 unclassifiahle 

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 SuspendedParticulate 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 cdata 

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 0, 1992. This is intended to 

provide EPA with time to make any 

technical corrections that are 

appropriate in light of the comments. 

3. Additional actians. 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 notifiecl 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 SOs, NOs, 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.0.12291, 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 df 

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, Novembe r6, 1991/Rule s and Regulations 56709 

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 

RegulRtory 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 

foll'ows: 

§ 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-10). 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 (S02), and nitrogen dioxide 

(NO:), 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 foe 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 an ended 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
