The purpose of this document is to announce and promulgate designations, classifications, and boundaries for areas of the country with respect to the NAAQS for ozone, CO, particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM-10), and lead in accordance with the requirements ofthe Clean AirAct (CAA). B.Preeanctment StatusandCleanAir ActAmendments (CAAA) of1990

The nation's first Federal efforts at controlling air pollution beganin 1963 with passage ofthe CAA. Four amendments followed in 1967, 1970, 1977 and 1990. The 1967Amendments directed the previous Department of Health, Education and Welfare to identify regional areas with common air 

### masses throughout the nation [Air Quality Control Regions (AQCR's)]. By 1970, 57 AQCR's were named. Later that year, 34 additional areas were announced.

The 1970 Amendments authorized the Administrator of thenewly created EPA to identify additional areas, butonly at the States' initiative. As ofJanuary 1972, 247AQCR's were listed.

Section 107(d) ofthe 1977 Amendments gave the EPAthe authority to designate areas nonattainment without a State's request. AfterEPA's initial designation ofareas as attainment/unclassifiable or nonattainment in 1978,however, subsequent designations couldbe made onlyat a State'srequest. In thatsame year,EPA published, for the firsttime,a list ofall section 107(d) nonattainment areas in40 CFR part81. C.CAAA andSubsequentEPAActions

This section summarizes therelevant provisions ofthe CAAA as applicable to ozone and COareas. A discussion ofthe provisions applicable to PM-10, SO2, 

### and lead areas is found in sections II.B., C.,and D.ofthis document.

The CAAA of1990 authorized EPA to designate areas nonattainment and to classifythem according to degree of severity. Classification, in turn, triggers a set ofcontrol requirements designed to bring areas intoattainment bytheir specified attainment dates.

Under the CAAA of1990, preenactment ozone and CO nonattainment areas were classified on the date ofenactment according to the severity oftheir problem. States were required, by 120days after enactment, to submit lists designating all areas ofthe State as attainment,unclassifiable, or nonattainment for ozone and CO.The EPA wasrequired topromulgate these lists by 240days afterenactment, making revisions, includingboundary 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.Chronologyof EPAandStateActions 1. CAAA of1990.The CAAA of1990 

### reaffirm themajorrole ofthe States in developing and implementing State implementation plans(SIP's) to attain theNAAQS. OnNovember 15, 1990, the day the CAAA were signedinto law, EPAAdministrator William K.Reilly sent a letterto State Governors alerting them to the significance ofthe legislation and summarizing the Amendments.

One month later, William G. Rosenberg, Assistant Administrator for Air and Radiation, followed up the November 15, 1990 letter with a second letter to State Governors. This letter notified Governors of those initial State actions orsubmittals rcquired ofStates, particularly those actions needed within a very shorttime period.

In January 1991, a thied letter to States went out from eachRegional Administrator providing more detailed information on determining designations, classifications, and boundaries; notification ofSIP deficiencies; and information about other early State actions. Attached to the letter was a listofcurrent and planned guidance materials thatwould be provided byEPA to support State activities.

2.Chronologyofevents.The first official actions the States took came45 days after enactment ofthe CAAA (December 30,1990). Preenactment ozone and/or CO nonattainment areas classifiedunder section 107(d)(4)(A)(iv) as serious, severe, or extreme would take as theirnonattainment area boundaries the boundary oftheir respective C/MSAunless the State notified theAdministrator, no latei than 45 days after enactment, ofits intent to study the boundaries further (the45-day letter].

In addition,under sections 181(a)(4) and 186(a)(3), EPAwas authorized to reclassify an area upward or downward (a "bump down") ifthe design value of an area placed it within 5percent ofthe next classification.The EPA requested that States seeking a bump down make the request within 45 days ofenactment. (Section 181(b)(3) provides thatEPA shall automatically grant therequest 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 EPAresponded to States' bump down requests.

OnMarch 15, 1991 (120 days after enactment), Stateswere required to submit to EPA a list ofall their ozone and CO nonattainment areas, including boundary recommendations. States were urged to submit at the same time SO2

### . PM-IO,and leadnonattainment areas, including boundary recommendations. States were encouraged toprovide at this time the additional boundary studies and recommendations for the serious, severe, and extreme ozone and CO areas covered bythe 45-day letters. By 56695569 Fedra Reite/olI6 No 5Wensdy Noebr6"91Rle n euain 

### May 14, 1991 (180 days after enactment), EPARegional Administrators notified States of any potential modifications to the States' recommendations. States were encouraged in the 180-day letter to respond to EPA's proposal within 20 days (by June 3, 1991, which is 200 days after enactment) for ozone and CO areas, and within 60 or 120 days, depending on the type ofmodification, forlead.Many States did so.

With respectto ozone and CO, today's action is final except for the following counties for ozone: Orange and Putnam (New York,New JerseyLong Island CMSA); Muskegon (Muskegon,MI); Washington (Parkersburg-Marietta, OH) and Pasco (Tampa,FL); and the following counties for CO: Hancock, Brooke, and Jefferson (Steubenville); and Utah (Provo, UT).

With respect to lead, PM-10, and SO2

### , refer to the appropriate section below for a description ofthe specific action being taken.

3.Presentation oftechnical information.Copies ofall ofthe above mentioned correspondence and other correspondence between the States, interested parties, and EPA regarding thisprocess are available forreview in the AirDocket No A-90-42 maintained in Rm. M-1500,401 M St., SW., Washington, DC 20460 (firstfloor ofthe EPA Washington DC, Waterside Mall Office). Identical information is also available for review at the EPA Regional Offices listed above in the addresses section ofthis rulemaking package.

Detailed discussions concerning the basis for EPA's actions and decisions are excluded fromthis rulemaking and are included in aTechnical Support Document (TSD). TheTSD is also available in the Air Docket and respective Regional Offices. Where appropriate in thisrule, the reader is directed to the TSD for additional information. II. Summary of Today'sAction A. Ozone/CO

1.Introduction.This section will describe EPA's interpretation ofthe designations/classifications/boundaries requirements applicable to ozone/CO areas; and itwill 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 thisrule. 2.Enactment-a.Designations/ boundaries/classifications-i. Designations. As described in this section, at the date of enactment, all areas ofthe country were designated with respect to ozone and COby operation of law in accordance with the preenactment designations. For areas that were designated nonattainment before enactment, EPAinterprets 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 ofenactment ofthe CAAA "is designated, by operation oflaw," as a nonattainment, attainment, or unclassifiable area, respectively.

-



### Section 107(d)(2)(A) requires EPA to publish a Federal Registernotice 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 therequirements discussed below, to promulgate the classifications and boundaries for these areas.

ii. Boundaries. Asnoted above, section 107(d)(1)(C) requires that each area designated preenactment ofthe CAAA be designated again, by operation oflaw, 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 ofthe date ofenactment, theTampa, Florida, area became designated nonattainment, but the specific boundaries of that area were to be determined subsequently.

Nevertheless, for certain purposes, each area designated by operation of law under section 107(d)(1)(C) retained itspreenactment boundaries at the date ofenactment. Forexample, locations within a metropolitan area that were designated nonattainment at enactment remained subject to the nonattainment new source review (NSR) requirements ofthe NSR programs EPA had previously approved for the nonattainment areas (under PartD of Title Iofthe Clean AirAct prior to the CAAA). The preenactment boundaries are identified in the version at 40 CFR part 81, Subpart C-Section 107 Attainment Status Designations (part81 tables), preceding the enactment ofthe CAAA. iii. Classificationslother treatmens(afGeneral -As described in this section, all areasdwith certain exceptions designated nonattainment by operation oflaw as of thedate of enactment were classified as of the date ofenactment in accordance with air quality.

Section 181(at(1yprovides: Eacharea designated nonattainmentfor ozone pursuanttosection 107d)shall be classified atthe time ofsuch designation undertable 1,byoperation oflaw, asa Marginal Area, aModerate Area, a Serious Area, a Severe Area, oran Extreme Area 

### based on the design value forthe area.

Section 186(a)(1) includes an identical ,provision forCO areas (except that the classifications are limited tomoderate or serious).

Based on these provisions,EPA has taken the position thatclassifications for areas designated nonattainient priorto enactment occurred at thesame time that those areaswere designated by operation oflaw as nonattainment under section 107d1(C}i), which was the date ofenactment. As discussed below, EPA has takenthe position that, for metropolitanareas thatincluded at least some locations designated nonattainment at enactment, such classification is not delayed until the timeofthe designations requiredto be promulgated 240 days afterenactment under section 107[d4n(Ae(ii).

Forozone, classification is to be based on thefollowing table ofdesign
Values (section 181(a)(1), table 1):

Area classification Design value (parts per Areaclasifictionmillion)
Marginal
.............................. 0.121 upto (but not including) 0.138 Moderate

............................. 0.138 upto (but not Including) 0.160 Serious ................................ 0.160 upto (but not

Including) 0.180 Severe-15
............................ 0.180 upto (but not including) 0.190 Severe-17

......... 0.190 upto (butnot including) 0.280 Extreme
............................... 0.280 and above



### Severe-15 and -17 areas (EPA's nomenclature] face the same requirements but differin their attainment dates (15 years for severe-15; 17 years for severe-17). Severe-17 applies to areas with a design value of .190to .280forozone years 1986-1988.

For CO, classification is to be based on the following table ofdesign values (section 186(a)(1), table 3):

Areaclassification Design value (ppm)
Moderate-i

.......................... 9.1-12.7 Moderate-2

.......................... 12.8-16.4 

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

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

Area classification Design value (ppm).

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



### EPA is distinguishing moderate-1 from moderate-2 (EPA's nomenclature) because ofthe 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 theAdministrator most recently before the date of the enactment" ofthe CAAA. This methodology is contained for the most part in a memorandum from William Laxton, Director, Technical Support Division, the Office ofAir Quality Planning and Standards, dated June 18, 1990 ("Laxton Memorandum"). Thismemorandum is contained in the TSD, item #1.

Section 181(a)(3) requires the publication in the Federal Register of
ozone classifications at the time ofthe publication ofthe notice under section 107(d)(4) (concerning designations). Section 186(a)(2) includes a comparable requirement for CO.This rulemaking fulfills those requirements.

-

Alisting ofthe classifications as they stood at the date ofenactment can be found in the pre-CAAA 40CFR part 81 tables mentioned previously.

(b) Years ofdata.Theprimary years the EPA usedfor purposes of designations and classifications pursuant to this notice were 1987-1989 (3-year period) forozone and 1988-1989 (2-year period) for CO.

In some cases, the EPA used complete 1988-1990 (ozone) or 1989-1990 (CO) data ifthey were quality assured and publicly available in theAIRS [Aerometric Information Retrieval System (EPA'sNational Air Quality Database)] by February 13, 1991, and the State requested the EPA to use it:

Forareas designated attainment prior to enactment, the EPA relied on 1990 data (ifquality 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 COyears, but then revealed attainment once again using 1990 data.

There are several reasons why the EPA began with the data years 1987- 1989 forozone and 1988-1989 for CO. The CAA required the Administrator to make a determination for 5percent classification downshifts no later than 90 days afterenactment (February 13, 1991). No later than 180 days after enactment (May 15, 1991), the EPA was required to notify States ofits intent to diesignate areas. Although some areas 

### had 1990 data available as early as February 13, 1991 and EPA considered it,most areas did not.Thus,in order to meet the deadlines set forth in the Act theEPAwas compelled for timing purposes to use 1987-1989 forozone and 1988-1989 for COas primary data years 

### in determining designations and classifications pursuant to this notice.

(c)Othertreatment.Some nonattainment areas werenot classified in accordance with theclassification tables under section 181(a)(1) or 186(a)(1) because ofspecific statutory 

### provisions orbecause theirair quality values didnot accord with the classification tables.

-



### (1)Submarginal. The EPAhas 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 ofless 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 theNAAQS exceedance rate of1.0 per year even 

### though theestimated design value is less than the level ofthe standard. More discussionofEPA's data requirements is contained in the TSD, item #2.

TheSIP submittal requirements of section 182 (concerning ozone)do not apply to these areas. A detailed discussion ofthese requirements will appearin theTitle IGeneral Preamble in aFederal Register scheduled for January 1992 publication.

(2)Transitional. Section 185A 

### provides that an area designated nonattainment by operation oflaw under section 107(d)(1)(C)(i) (byvirtue of its designation asnonattainment prior to enactment ofthe CAAA), which "has notviolated the [NAAQSI" for ozone during the 1987-1989 period is to be 

### treated as a transitional area. Section 185A further requires EPA to determine, byJune 30, 1992, based onthe transitional area's "design value asof theattainment date" whether the area attained theNAAQS by December 31, 1991.



### The EPA interprets this provision to require EPA touse its standard methods for determining attainment or nonattainment to ascertain whether an area is atransitional area and to determine whether the area attained the NAAQS by December 31, 1991. There must be sufficient data (75 percent completeness for eachyear) to determine that the area hasnotviolated the standard. Abriefdiscussion ofthese procedures isincluded in the TSD, item #3. (3) Ozoneincompletedataareas. 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 EPAdoes not believe sufficient data (75 percent completeness for each year) exist to warrant a classification for the area. The EPA terms these areas "Incomplete Data Areas."

As a result, the SIP submittal requirements ofsection 182 (concerning ozone) do not apply to these areas. A detailed discussion ofthese requirements will appear in the Title I General Preamble in a Federal Register scheduled forJanuary 1992 publication.

(4) CO "notclassified" areas.Certain CO areas are designated nonattainment by operation of law as ofthe date of enactment by virtue oftheir preenactment designation of nonattainment. These areas did not experience a violation ofthe 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 in1988-1989. Where EPA concluded there wouldhave 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 ofsection 187 (concerning CO) do not apply to these areas. A detailed discussion ofthese requirements will appear in the TitleI General Preamble in a Federal Register scheduled forJanuary 1992 publication.

(5)Ruraltransport areas(ozone). Section 182(h) sets out general criteria for determining whether an area qualifies as a rural transport area. The statute defines it as an area which is designated nonattainmcnt and neither includes noris adjacent to any part ofa C/MSA. In such cases, the Administrator in his discretion may treat the area as a rural transport area based on a finding that the emissions within the area do not make a significant contribution tothe 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 forAssessing the Role of Transported Ozone/Precursors in Ozone Nonattainment Areas."

This section also provides that arural transport area, regardless ofits classification, is treated as meeting the 56697

### 56698 Federal Register/Vol. 56, No. 215/Wednesday, November 6, 1991/Rules and Regulations
applicable requirements ofsection 182 (generally relating to submissions required for ozone areas classified from marginal toextreme) ifthe area meets the submission requirements ofa marginal area.

The thrust ofthisprovision is to allow a rural transport area, the design value ofwhich would otherwise indicate a classification forthe area ofmoderate or higher, to be treated as a marginal area.

3.Enactment+ 45days: C/MSA boundary processbegins-general requirements.Section 107(d)(4)(A)(iv) provides that areas designated nonattainment at the date ofenactment, and classified as serious orhigher, would, by operation oflaw45 days after the classification, take as their boundaries the MSA or C/MSA, unless the State submitted a letter before that date indicating that it wished to study the boundary question further.Because areas designated nonattainment by operation oflaw at the date of enactment were also classified at that time, as described above, this 45-day periodbegan from the date ofenactment and ended on December 30, 1990.

Areas for which no 45-day letter was submitted took as their boundary the larger oftheir preenactment boundaries or the C/MSA. These areas are identified in section 8a(1) ofthis document.

Areas for which a 45-day letter was submitted are identified in the TSD, item. #4, and copies ofthe letters are in Docket A-90-42. For these areas, the State was given the opportunity to submit toEPA a study describing why parts ofthe 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. IfEPA concurs in thefinding, based on the State study,by 14 months after classification (January 15, 1992), the boundaries will be reduced accordingly. IfEPA does not concur by that date, the boundaries will become the C/MSA by operation oflaw.

4.Enactment+ 90days:5percent classificationadjustment-a.General. Under sections 181(a)(4) and 186(a)(3), an ozone or CO nonattainment area may be reclassified to the next higher or lower classification ifits design Value places it within 5 percent ofthe next classification. Forozone, section 181(a)(4) provides that such reclassification must occur no later than 90 days after the initial classification, which is (1)90 days after the date of enactment (by February 13, 1991) for areas designated nonattainment by operation oflaw under section 107(d)(1)(C) (by virtue oftheir designation as nonattainment preenactment); or (Z)90 days after the effective date ofthis rulefor areas designated nonattainment for ozone for the first time pursuant to thisrule (by virtue oftheir designation as attainment preenactment). For CO, section 186(a)(3) provides that such reclassification must occur no laterthan 90 days after enactment. The provisions grant the Administrator broad discretion in making, ordetermining not to make, the reclassification.

b.EPA criteria.Section 181(a)(4) provides general guidelines in determining whether an area qualifies for a classification adjustment:

Inmaking such adjustment, the Administrator mayconsider the number of exceedances ofthe national primary ambient airquality standard forozone in the area, the level ofpollution transport between the area and otheraffected areas,includingboth intrastate and interstate transport, and the mixof sources and airpollutants in the area.

The EPA has developed more specific criteria (discussed below) to evaluate whether it is appropriate to reclassify a particular area. These criteria are primarily applicable to downshifts. The EPA approved downshifts when the area met the first requirement (a request by the State to EPA) and at least some ofthe other criteria (emissions, reductions, trends, etc.) and did not violate any ofthe criteria.

Requestby State:EPA did not exercise its authority to downclass (or upclass) areas on EPA's own initiative. Rather, EPArequested that the State submit a request for a downshift.

Discontinuity- A 5-percent downshift mustnot result in an illogical or excessive discontinuity relative to surrounding areas. Inparticular, in light ofthe area-wide nature ofozone formation, a downshift should not create a "donut hole" where an area ofone classification is surrounded by areas of higher classification.

Attainment:Evidence shouldbe available that theproposed area would be able to attain by the earlier date specified by the lower classification.

Emissionsreduction:Evidence should be available that the area would be very likely to achieve the appropriate total percent emission reduction necessary in order to attain in the shorter time period.

Trends:Near- and long-term trends in emissions and air quality should support a downshift. Historical air quality data should indicate substantial air quality improvement. Growth projections and emission trends should support a - downshift. Vehicle miles traveled (VMT) 

### and other indicators ofemissions should notbe increasing at higher than normal rates. Yearsofdata:Forozone, the 1987- 1989 period is central to determining classification. Years ofdata after 1989 may be employed to corroborate the 

### validity ofa downshift. However,later years of data shouldnotbe thesole foundation fordownshifts.



### Only one downshift is allowed, meaning, ifdownclassed, an area cannot 

### present data from other years as justification fora second downclass.



### Under no circumstances can theuse of1990 airquality data be used to redesignate an area fromnonattainment to attainment. Forredesignation to attainment, thearea must meetall ofthe requirements ofsection 107(d)(3) (including a maintenance plan).

c.EPAaction.Areas requesting a downshift per section 181(a)(4) and EPA's response to those requests are contained in theTSD, item #5.

d.Reclassificationsupward.Section 181(b)(3) provides thatEPA shall automatically grant therequest ofany State toreclassify an ozone nonattainment areato a higher classification. This requirement requires 

### EPA to "publish anotice in theFederal Register ofany such request and ofany action by the Administrator in granting such request."

On December 27, 1990, EPAreceived a request from the State ofMaine to reclassify Lincoln Countyupward from marginal to moderate. By this notice, 

### EPA is granting that request.

OnDecember 28, 1990,EPA received a request from the State ofCalifornia to reclassify Ventura County from serious to severe. Ventura County ispart ofthe Los Angeles C/MSA, whichis classified as extreme, and California has requested (pursuant to the45-day/14- month process described above) that Ventura County be treated as a separate nonattainment area. California's request toreclassify Ventura County to severe is based on an assumption that Ventura County wouldbe treated as a separate nonattainment area. Asdiscussed below,EPA is,by thisnotice, approving California's request to treatVentura County as a separate area classified as severe.

Section 182(b)(3) does notby its terms place time limits onthe opportunity of a Statetorequest a voluntary reclassification upward. Accordingly, States may continue to submit such. requests. However, suchreclassification willnot delay the SIP/submittal dates otherwise applicable under subpart 2o' Title Iofthe CAAA.

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

5.Enactment+ 120 days:State submitslistofallareas-general. Section 107(d)(4)(A)(i) requires States to submit a list designating, redesignating, oraffirming the designation ofall areas ofthe State as nonattainment, attainment, or unclassifiable for ozone and CO by 120 days after enactment.

Virtually all the States met this requirement on a timelybasis. Copies of the States' 120-day letters are included in Air Docket A-90-42.

For areas designated nonattainment at the date ofenactment of the CAAA, and classified as marginal or moderate, this listmust include the boundaries of the areas.

For areas designated nonattainment at the date ofenactment ofthe 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 theirboundary 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.

Forareas designated attainment or unclassifiable at the date ofenactment, States were required toredesignate these areas to nonattainment iftheir current air quality revealed nonattainment. These areas are identified in Part III. The applicability to these areas of the opportunity forthe 5 percent reclassification and, in the case ofareas classified serious orhigher, 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 submitwith their 120-day (March 15) submittals any analyses supporting areclassification or boundary revision, and EPA would consider taking final action on these issues with today's notice.

6.Enactment + 180days:EPA notifiesStatesofintenttomodify suggesteddesignations forcertain areas.Section 107(d)(4)(A)(ii] and (1)(B)(ii) provides thatEPA may modify the designations, classifications, and boundaries submitted by the State at 120 days, but that ifEPA intends to do so, it must notify the State ofEPA'sproposed 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), EPAproposed modifications to various State submissions. These modifications are summarized laterin this document and/ orin more detail in the TSD.

7.Enactment + 200days:States respondtoEPA'sproposed modifications.Consistent with section 107(d)(4)(A)(ii) and (1)(B)(ii), EPA provided the affected States with an opportunity to demonstrate why any of EPA's proposed modifications were inappropriate. The EPA requested that the affected States submit such demonstrations by June 3, 1991, so that EPA could meet the statutory deadline for promulgation offinal designations, classifications, and boundaries. The States' responses are included inAir Docket A-90-42.

8.Enactment + 240days.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 EPAis taking that action with this notice.This section discusses those actions in several separate parts:

(1)Areas designated nonattainment at date ofenactment-classified serious and higher.

(2) Areas designated nonattainment at date ofenactment-ozone areas classified marginal or moderate and CO areas classified moderate.

(3)Other areas designated nonattainment at the date of enactment-treated separately from the classified areas.

(4) Areas designated entirely attainment/unclassifiable at enactment, but now redesignated to nonattainment.

(5) Areas designated attainment/ unclassifiable at enactment and that now retain that designation.

a.Ozone andCOareasdesignated nonattainmentatdateofenactment-- classified seriousandhigher. With respect to areas designated nonattainment for ozone or CO at enactment and classified serious or higher, and forwhich the Governor did not submit a 45-day letter, the area took as its boundaries, 45 days after enactment, thelarger oftheir preenactment boundaries or the C/MSA boundary.Today's notice affirms those boundaries. Any areas not included in the boundaries ofthese 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 ofenactment, as described below.

With respect to areas designated nonattainment forozone or CO at enactment, classified serious orhigher. forwhich the Governor submitted a 45- day letter (thereby beginning the C/ MSA boundary-determination process) and has submitted the relevant boundary data, this notice promulgates these boundaries. (1)EPA Actions:

Following are the serious and higher classified areas for which the entire C/ MSA was already designated at enactment by operation oflaw (because the preenactment boundaries ofthe nonattainment area included the C/ MSA), orthe remaining attainment
areas were added by the State. (See Air Docket No. A- 90-42 for official designation correspondence between the States and EPAon each area.) In addition, for two areas, theWashington, DC, MSA and Philadelphia CMSA, the entire C/MSA is designated due to absence ofa 45-day letter from the State requesting more time to evaluate boundaries (Stafford Co., VA, became part ofthe Washington, DC, nonattainment area and Cecil Co.,MD, became part ofthe Philadelphia nonattainment area).

San Diego, CA SanJoaquin Valley, CA Philadelphia, PA-NJ-MD-DE Washington, DC-MD-VA Baton Rouge, LA Boston,MA Greater Connecticut (NewLondon portion)

New York City (NewJersey portion) Springfield, MA Beaumont, TX El Paso, TX Houston, TX Milwaukee, WI Sheboygan, WI The San Joaquin Valley, CA, area includes the MSAs ofBakersfield, Fresno, Visalia-Tulare-Porterville, Modesto,Merced, and Stockton, and the counties ofKings and Madera. The Greater Connecticut nonattainment area consists ofthe Hartford-New BritainMiddletown CMSA, the Waterbury, CT, MSA,the New London-Norwich, CT-RI, MSA, and the New Haven-Meriden, CT, MSA,including some ofthe previous planning areas in the State.

By this notice EPA is promulgating the boundaries ofthe following seven areas as smaller than the C/MSA. For these areas, the portions ofthe C/MSA not included in the nonattainment area 

### 56699

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

become either (1)separate nonattainment areas with a lower classification, or (2)adjoined to another, contiguous nonattainment area withthe sameor lower classification. The States and EPAare in agreement with respect to these actions. Under section 107(d)(4)(A)(v), EPAmaypromulgate boundaries smaller than the CIMSAifit concurswith a State findingthat sources in theexcluded portion "do not contribute significantly" to theviolation of theNAAQS. This provision identifies several factors that may be considered.

In general, EPA supports its decision toconcur with the State's finding with respect to these areas onthebasis ofa facts-and-circumstances testthat focused onwhether sources in the area at issue contributed significantly to' NAAQS violations inthe C/MSA.The EPAdid notdevelopbright-line criteria, butinstead,examined suchfactors as the amount ofemissions fromwithin the area at issue and its percentage contribution to the CIMSA (or surrogates for emissions data, such as population] and ifavailable, theresults ofmodeling studies.

Baltimore. MD-Kent and Queen Annes Counties become a separate marginalnonattainment area.

Los Angeles, CA-Ventura County becomes a separate severe-15 area. Southeast desertmodified (AQMA) becomes a separate severe-17 area.

Portsmouth,NH-ME-The Maine portions ofPortsmouth become part of the Portland, Maine, nonattainment area.

Chicago, IL-Kenosha County becomespart oftheMilwaukee-Racine nonattainment area.

New London-Norwich MSA (Rhode Island portion)-Westerly and Hopkington become part ofthe Providence nonattainment area.

New YorkCity (Connecticut portion)-Ansonia City, BeaconFalls Town, Derby City, Milford City, Oxford Town, Seymour Town and Shelton City become part ofthe Greater Connecticut nonattainment area.

Boston, MA-All Massachusetts towns which were previously part ofthe Providence CMSA become part ofthe Boston nonattainment area.

In addition, EPA believes that it may concur inreassignment ofaportion of the C/MSA to another nonattainment area when thatreassignment results in the same, oressentially the same, classification-under the deminimis authority ofAlabama PowerCo. v. Costle, 636F.2d 323, 360-61, 404-05 (DC Cir.1980). This case held thatEPA may exempt de minimis situations from a statutory requirement when the burden ofregulation would yield little orno value. In these cases, EPA believes that applying the "contributes significantly" test to these areas would yieldno gain in airquality since control requirements remain the same despite the reassignment, and thus neither area's prospects for reaching attainment and maintenance isjeopardized. Applying de minimisauthority to these cases remains consistent with the underlying purpose ofthe nonattainment provisions, which is to assure attainment and maintenance ofthe NAAQS. (Seethe TSD, item #8, for technical documentation supporting these determinations.)

In addition,bythis notice EPA is promulgating theboundaries ofthe following five areas as smaller than the C/MSA. Forthese areas, the removed portions ofthe C/MSAs remained attainment. (See theTSD, item #7,for technical documentation supporting these determinations.) Following is a listingofthe C/MSAs and thecounties which remain attainment.The States and EPAare inagreement with respect to these actions. Ozone

For thefollowing serious areas, States requested in a letter (45-dayletter)more timeto evaluate theirboundaries per section 107(d)[4)(A)[iv). The Administrator has notyet made a finding on these two areas.

Muskegon, MI. New YorkCity (Orange and Putnam Counties, NY).

In a May 14, 1991letter to these States,EPA requested that all documentation pertaining to any proposed boundary changes be submitted as soonas possible, butno laterthan August 12, 1991.



### New York Statefollowed with a letter onJune4, 1991, requesting more time to evaluate the boundaries ofOrange and Putnam Counties and informed EPA that the appropriate documentation would be submitted nolater than the August 12. 1991 deadline.

The State ofMichigan confirmed its intent to continue studying itsMuskegon boundary issuein a June 18, 1991 letter to EPA.

OnJanuary 15.1992. nonattainment boundaries willbecome theentire Cl MSA for both theNew York and Michigan areasdiscussed above unless theAdministrator has concurred with theGovernors' finding that a smaller boundary is more appropriate. The EPA is awaiting theState's studies.The final determinations willbe promulgated in a separate Federal Register notice.

b. Ozone andCO areasdesignated nonattainment atdateofenactmentclassified marginal ormoderate-i. Designations. For areas designated nonattainment for ozone or COby operation oflaw under section 107(d)[1)(C) atthe dateofenactment, EPA, withtoday's action,reaffirms that designation. Section 107(d)(4)(A)(iii) precludesredesignating an areato attainment under this240-day process.

ii.Boundaries.Ata minimum, the nonattainment boundaries should include those areas designated nonattainment prior to enactment. For purposes ofdetermining sources subject to new source review, thispreenactmen' boundary applies. Where itmay be appropriate to expand the nonattainment boundary beyond the existing boundary,States should treat these additional areas as subject to the appropriate other CAA requirements. -

Section 107(d)(4)(A)(i)-(iij authorizes EPA topromulgate a designation of "nonattainment" for an area. Section 107(d)(1)(A)(i) defines a nonattainment" area asanyarea that doesnot meet (orthat contributestoambient air quality inanearby areathat does notmeet)the [NAAQSJ.

This provisionbases the determination ofwhether an area is nonattainment onairquality considerations-ifthe airquality ofan areaviolates theNAAQS, or ifsources in that area contribute to NAAQS violations in anearby area, thearea mustbe designated nonattainment. However,the provision doesnot byits terms specify criteriafor determining the extent to which source contributions mandate designation asnonattainment. Accordingly. the statute grants EPA discretionin making thisdetermination. 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 ofall areas in the State, with its designations, and

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

authorizes EPAto make "such modifications as theAdministrator deems necessary to the designations of the areas 

### (orportions thereofn * 

### * * 

### (including to the boundaries ofsuch areas or portions thereof)."

These statutory provisions provide guidance for the determination of whether an area is to be designated nonattainment. Theydonot, however, provide explicit criteria fordetermining thespecific boundaries ofthe nonattainment area. Theydonot specifically address the issue ofwhether a geographic area designated nonattainment mustbe one nonattainment area, or whether the State orEPA may divide that area into two or more nonattainment areas. Accordingly, the statute grants EPA discretionin making this determination.

The EPA will grant a strong presumption in favor ofthe designations and boundaries put forthby the States. TheEPA believes that this is an acceptable approach since bydefinition, the nonattainment areas classified as marginal and moderate have less severe ozone or COproblems and are likelyto reach attainment through Federal measures which generally apply independent ofboundaries.

Accordingly, EPAhas determined in most cases to accept the State-proffered designations andboundaries. Ingeneral, EPAis not discussing in this document orin the TSD, designations, boundaries, and/or classifications issueswhere EPA isin agreement with the State's request. However, where EPA is disagreeing with a State's proposed action, a detailed discussion oftheissue, including EPA'sreasons, follows.

TheEPA, inseveral instances,is still studying whether to expand ozone nonattainment areas withina C/MSA to include additional counties in that C/ MSA when those counties may be of such greatpopulation or such a large percentage ofthe C/MSA's population that sources in those counties maybe contributing to the nonattainment problem in the C/MSA. These counties are: PascoCounty, in theTampa, Florida, MSA; Washington County in the Parkersburg-Marietta, Ohio, MSA. For these areas, as noted in the accompanying tables ofthis document, the listed designation does notreflect EPA action under section 107(d)(4)(A). At the date ofenactment ofthe CAAA, these two counties were designated attainment, byoperation oflaw,under section 107(d)(1)(C). The State and EPA are reviewing whether to confirm or reverse their present designation under the process set out under section 107(d)(4)(A) and will publish a separate noticc to thateffect. In a number ofinstances occurring across thenation, counties that may generally be considered to berural due torelatively small populations and a relatively low degree ofurbanization have contained a monitor that has recorded an ozone NAAQS violation. In some ofthese instances, the States, in the 120-day submissions ofthelists of areas, electednot to designate these areas as nonattainment. Inthese cases, EPA informedthe State in EPA's 180- day letterthat such counties (or subcounties) must be designated as nonattainment onthe grounds that section 107(d)(1)(A)(i) defines a nonattainment area as,among other things, "any area that doesnot meet... the [NAAQSI."

Some States did notwishto designate the entire county.In these cases,EPA generally agreed to designate onlya portion ofthe county nonattainment. To determine theboundaries ofthese nonattainment areas, orthe extent to which neighboring nonattainment areas should be expanded to include all or part ofthese counties, EPA has determined to apply the following criteria.

Presumptively, the nonattainment area shouldinclude the entire county. If thecounty doesnot adjoin any nonattainment area, the presumption in favor ofan entire county is stronger. The boundaries may be reduced to less than an entire county ifit is possible to delineate the boundaries ofthe area involving the NAAQS violation, andifit can be shown that certain other areas within the county likely do not contribute to the NAAQS violation.

Inparticular, ifa county adjoins a nonattainment area, thepresumption in favor ofdesignating theentire county nonattainment mayberebutted, and EPAwill designate boundaries narrower than the entire county,in accordance with thefollowing criteria.

The portion ofthe county designated nonattainment mustbe contiguous with the adjoining nonattainment area, include the area surrounding the monitor,and include all adjoining areas withpopulations ofsufficient density such that these areas are likely to contribute to the NAAQS violation. Furtherexplanation ofthese criteria and oftheirapplication to individual cases is included in the TSD, item #8.

Based onthese criteria, EPA is today promulgating thefollowing nonattainment areas: Ozone 

### NorthCarolina

On May 13, 1991, EPARegion 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 ofNorth Carolina, EPA believes that emissions originating in the counties ofDavie and Granville do not merit inclusion of each entire county as nonattainment. However, since these counties have monitored violations ofthe NAAQS, at least a portion ofthe county must be designated nonattainment. The EPA is therefore designating areas smaller than the counties as nonattainment for Davie and Granville Counties. Theboundaries chosen for each of the areas include the monitor and an area that includes the
more urbanized portions ofthe county thatis contiguous with the rest of the nonattainment area (the GreensboroHigh Point-Winston-Salem MSA for Davie County; and the Raleigh-Durham MSA forGranville County). The rationale for this action is that this boundary includes the area in which the air quality is nonattainment and in which sources likely to contribute to the nonattainment problem are located. SouthCarolina

The Cowpens monitor in the northwest comer ofCherokee County (non-MSA)measured violations ofthe NAAQS during the 1987-1989 period and therefore mustbe designated nonattainment. Since there is uncertainty at this time as to the origin of the source of the emissions causing theviolations 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 ofthe following five counties in the Commonwealth ofKentucky forthe
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 ofthe source of the emissions causing the violations in a sixth county-Edmonson County (Bowling Green non-MSA)-the entire 

### 56701
I

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

county is designated nonattainment and classified as a rural transport area. (See the TSD, item #9, for documentation supporting a rural transport classification.) Virginia

Virginia proposed that Charles City County (RichmondMSA] and the Cityof Suffolk (Norfolk MSA) remain attainment By today's notice, EPA is designating both ofthese counties as nonattainment because ofmonitored violations within them. CO NewJersey

The State ofNew Jersey stated in a letter dated June 28, 1991, that, while it iswilling to accept EPA's nonattainment boundaries for CO,it requests that these nonattainment areasbe classified as "low moderate" (12.7 ppm and below).

The EPAbelieves thatthe nonattainment area is comprised ofthe contiguousjurisdictions ofNew York City,Nassau and Westchester Counties inNew York, and Bergen, Hudson, Essex and Union Counties and the cities ofPassaic, Clifton and Paterson in New Jersey. The highest CO concentrations measured within this area are in Manhattan, in the center ofthe 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 thepotential to contribute to the maximum measured levels.

The NewJersey counties in the area rank among the State leaders in such categories as vehicle miles traveled and population density per square mile. These New Jersey counties are not distinguishable from the New York counties surrounding Manhattan. Therefore, based on thisrationale and the measured concentrations in Manhattan (13.5 ppm), the northern New Jersey portion of the New York-New Jersey-Long Island CMSA nonattainment area retains the same classification (highmoderate) as the CMSA, which includes northern New Jersey. Tennessee

On March 12, 1991, Governor McWherter and Commissioner Luna submitted the recommendation that the City ofMemphis be designated as a moderate nonattainment area for CO. The City ofMemphis was designated nonattainment forCO prior to enactment ofthe CAAA. On May 13, 1991, in a letter to Governor McWherter,EPA recommended that the CO nonattainment area be expanded from the City ofMemphis to all ofShelby County. This designation is based on contribution to the mobile source CO emissions in the portion ofShelby County outside ofthe City ofMemphis, 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 ofthe City ofMemphis 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 forthe City of Memphis. Since automobile registration is done on a countywide basis without regard to whether ornot the vehicle is located within the City ofMemphis, it is difficult ifnot impossible to verify whether the appropriate vehicles are actually subject to theI/M program. The expansion ofthe nonattainment area to the entire county will give the State a basis for expanding coverage of theI/M program.

On May 31, 1991, Commissioner Luna wrote a letter to EPARegional 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'sproposal to expand the Memphis CO nonattainment area. Utah

The EPAis still studying whether to expand theProvo CO nonattainment area. As noted in the accompanying tables of this document, the listed designation does not reflect EPAaction under section 107(d)(4)(A). At the date ofenactment ofthe CAAA, that portion ofUtah County outside the city limits of Provo was designated attainment by operation oflaw under section 107(d)(1)(C). The State ofUtah 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 oflaw at the date ofenactment were classified at that time, and by today's notice,EPAis announcing the classifications as required under sections 107(d)(4)(AI(ii), 107(d)(2), 181(a)(3), and 186(a)(2). Areas designated nonattainment at the date of enactment are not being classified anew by today's notice: rather, that classification occurred at the date of enactment, and EPA today ismerely announcing andcodifying in the CFR the classifications that occurred for these
areas at enactment.-

The EPA basesthis approach primarily on the provisions ofsection 181(a)(1) and section 186(a)(1), each of which provides (in relevant part, using identical terms): "Each area designated nonattainment... pursuant tosection 107(d) shall be classified at the time of such designation." Section 107(d)(1)(C)[i) provides thateach ozone and CO preenactment nonattainment area is "designated, by operation of law, as a nonattainment area." This designation occurred at the date of enactment. -

The factthat classification occurred at the date ofenactment means that the clock began ticking on the date of enactment for certain events triggered by the classification, specifically, the 90-day opportunity for 5 percent reclassification, and the 45-day period for States to submit requests to study .theboundaries of areas classified. serious and higher. ForCO nonattainment areas, section 186(a)(3) provides that the 5percent reclassification mustoccur "within 90 days after the date ofthe enactment" thereby confirming that classification for CO under section 186(a)(1) occurred on. the date ofenactment. Because the relevant provisions ofsection 181(a)(1) for ozone areidentical 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 forareas containing locations designated nonattainment at enactment. The House Committee Report confirms this view by stating that the 5percent reclassification adjustment forozone may occur "{Iwjithin 90 days of enactment" [H.R. No. 101-490, 101st Cong., 2d Sess.231-32 (1990)].

-

Areas classified at the date of enactment arenot reclassified again by virtue of the fact that today's notice reaffirms the designation ofthose areas and includes certain nearby locations withinthe boundaries of those areas. The EPA takes the position thatbecause they are not again classified, they are not again given the opportunity to make a 5 percent reclassification, or,in the case ofareas classified serious or higher, to initiate new efforts to adjust the boundaries to smaller than the C/ MSA.Interpreting the CAA to allow such opportunities would be inconsistent with congressional intent to expedite the preliminary questions of designations, classifications, and boundaries in orderto assure that the heart ofthe program-the pollution

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

controls themselves-are in place as quickly as possible [see H.R. No.101- 490, 101st Cong., 2d Sess., 232 (1990) (stating that a period ofonly 90 days is provided for the5 percent reclassification "to assure that State and EPA resources are devoted to efforts to attain the standard, and not to changes in the classification ofareas")1.

Although in some cases the boundaries for an area remained undetermined until today's notice (i.e.,
areas containing at least some portion which was attainment at enactment), all
areas ultimately determined to be within those boundaries and promulgated in this document are considered to be part ofthe nonattainment area designated and classified at the date ofenactment. As a result, with respect to any neighboring area that is ultimately included in the nonattainment area, no new classification has occurred with today's notice, and there is no opportunity for a 5 percent reclassification or a45-day C/MSA process.

The following are specific actions EPA is taking with respect to classifications. Arizona

In a May 15, 1991 letter, Governor Symington ofthe StateofArizona recommended an ozone classification of transitional for Maricopa County (Phoenix area) pending verification of ozone data for calendaryear 1990 and additional studies tobe conducted during 1991 to determine the appropriate designvalue. Additional quality-assured monitoring data for 1990 from two monitoring sites in Maricopa County (Papago Park and Vehicle Emissions Lab) made available since receipt of the Governor's original recommendation indicate that a classification of moderate is more appropriate forthe Phoenix area. Based on this additional, quality-assured data, EPAis classifying Phoenix as a moderate area for ozone. Ohio

OnMarch 15, 1991, the State ofOhio recommended thatMahoning and Trumbull Counties be redesignated from nonattainment to attainment. TheEPA previously disapproved a redesignation request for this area on July 10, 1990 (see 55 FR 28199). Mahoning and Trumbull Counties will remain nonattainment because section 107(a)(4)(A)(iii) does not permit redesignations to attainment
as part ofthisgeneral 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). Thismonitor islocated in the urban area ofYoungstown and may not represent theworst-case ozone concentration in thearea. This is due to the suppression ofozone formation by NOx in the urban area.The monitor in Youngstown hasnot recorded a violation ofthe ozone NAAQS based on 1987 through 1989 monitoring data.The second monitor is located downwind in Farrell, Pennsylvania (Mercer County, Pennsylvania). This monitorhas recorded a violation oftheozone NAAQS based on 1987through 1989air quality data (2.1 average expected exceedances peryear). Aviolation of theNAAQS occurs when the average expected exceedances peryear is greater than 1.0.The monitoring site in Farrell, Pennsylvania, is approximately 1to 2miles to theeast ofTrumbull County,Ohio. TheEPA has determined that the monitoring sitein Farrell, Pennsylvania, may havebeen adversely impacted byemissions fromMahoning and Trumbull Counties (see 55 FR28199, July 10, 1990).This is based on the prevailing warm weather (ozone conductive) winds in the upper midwest. Since the windstypically blow from the quadrant bounded by thedirections south and west, theFarrell site is expected tobe downwind on these days. Based on this information Mahoning and Trumbull Counties,Ohio, are being classified, along withMercer County, Pennsylvania, as a marginal ozone nonattainment area with a design value of .134ppm. 

### Pennsylvania

In a March 18, 1991 letter, Pennsylvania proposed that Lawrence County be designated "cannot be classified orbetter than primary standa-ds" forozone. To support its recommendation, the Statepointed out that ozone NAAQS attainment hasbeen monitored at a location in that county. Per section 107(d)(1)(C)(i), an area designated nonattainment preenactment ofthe CAAA of1990 mustbe nonattainment postenactment.

Inthe same letter,Pennsylvania proposed that Allegheny Countybe designated "cannot be classified or better than primary standards" for carbon monoxide. TheState bases its recommendation on thefactthat the county ismonitoring attainment.Again, as Allegheny County was designated nonattainment priorto passage ofthe CAAA, the area remains nonattainment by operation oflaw until a carbon monoxide NAAQS maintenance plan is developed and approved byEPA. In the tables section ofthe 107 classification/ designation notice EPA recognizes the fact that Allegheny County is not violating the NAAQS. i.e., that it is monitoring attainment.

c. Othertreatment.With today's notice, EPA is also promulgating the affirmed or reaffirmed designations (and new, affirmed, orreaffirmed boundaries) ofnonattainment area3

### tobe treated as transitional (ozone), submarginal (ozone), incomplete data (ozone), not classified(CO), and rural transport areas (ozone); and codifying its conclusion thatthose areas should be accorded that treatment. These uzeas are listed in the TSD, item #10.

d.Areasdesignated entirely attainment/unclassifiable atenactment butnowsubjecttoredosignationto nonattainment- i. Seriousandhigher. Ohioand West Virginia

As noted in the accompanying tables ofthis document, the lsted designation forthe Steubenville, OH-WV nonattainment area does not reflect EPA action under section 107(d)(4)(A). At the date ofenactment of the CAAA, the three counties which make up the Steubenville MSA-Jefferson County, Ohio; Brooke County, West Virginia; and Hancock County, West Virginiawere designated attainment, by operation of law, under section 107(d](1)(C). The States and EPA are reviewing whether to confirm or reverse this present designation under the process set out under section 107(d)(4](A). TheEPA will publish a separate notice to that effect.

ii.Marginal/moderate. With today's notice, EPA is promulgating the designations, classifications, and boundaries for three areas, Smyth County, Virginia; Essex County, New York; and Jefferson County, New York. These areas were designated entirely attainment as ofthe date ofenactment; however, current air quality necessitates a designation ofnonattainment under section 107(d)(4)(A)(i)-(ii). Fornew ozone nonattainment areas, because they are classified as ofthe effective date of today's notice, any reclassification based on the 5percent provision of section 181(a)(3) must occur within90 days ofthat effective date. The criteria for making the 5percent reclassification will be the same as discussed above. Smyth and Essex Counties are rural transport areas. Therefore, a 5percent downshift is not applicable to either area.

On March 21, 1991, the Governor of New York requested a 5percent downshift for Jefferson County since its design value of.143 ppm fell within 5 percent ofthe marginal classification. 

### 56703

### 56704 Federal Register/Vol. 56, No. 215/Wednesday, November 0, 1991/Rules and Regulations
Today's notice approves thisrequest and reclassifies Jefferson County as a marginal nonattainment area per section 

### 181(a)(4). Essex County,New York

New York State requested inits March 21, 1991 letter that Essex County (non-MSA) be designated attainment. The State based this request on thefact that the monitoring station on which the designation is based is partof an atmospheric research station on the top ofWhiteface Mountain, and on the beliefthat the measurements taken at this station do not reflect general air quality in the region. NewYork 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 ofozone is the cause of theviolations.

It is EPA's position that the violations ofthe 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 ofthe Lake Placid recreational area, Adirondack Park, a year-round resort location. Since the State's June 4, 1991 letter, additional exceedances of the ozone standard, including some day-time readings, have been recorded at this location.

The EPA does agree that long range transport appears to be a substantial contributor to the NAAQS violations on Whiteface Mountain. Given violations have occurred only at a higher elevation while attainment is measured at the base ofWhiteface Mountain, EPA has determined that a smaller boundary, as defined by those areas on Whiteface Mountain above an elevation of4,500 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 ofEssex County to remain attainment. The EPA believes this boundary adequately includes the monitor, located at an elevation of4,867 feet, and a reasonable surrounding area.

By selecting4,500 feet as the boundary marking the nonattainment area ofWhiteface Mountain, EPA also believes that the air quality in the 

### Adirondack Park area, an area frequented by the public, willbenefit by designating thisportion ofEssex County as nonattainment.

TheEPA also agrees with the State that a rural transport status more accurately reflects the ozone nonattainment problem inEssex County at Whiteface Mountain.Documentation supporting a classification ofrural transport is contained in the TSD, item #11. Smyth County, Virginia

In a March 15, 1991 letter to EPA, GovernorWilder ofthe 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 Governorof Virginia that,while acknowledging strong evidence oflong-range ozone transport, at least a portion of Smyth County must bedesignated nonattainment.

In a June 3,1991 letterto EPA Region III, theState ofVirginia recommended designating the area in SmythCounty above 4,500 feet as nonattainment and continued torequest a classification of rural transport.

The EPA recognizes themonitored violations bydesignating the area in Smyth County above 4,500 feet elevation as nonattainment, as recommended by theState ofVirginia in theirJune 3,1991 letter to EPA.TheEPA accepts this elevation as a boundary to define the nonattainment area as EPA believes it adequately includes themonitor, located at 5,520feet, and a reasonable area surrounding it.

Selecting 4,500 feet as the boundary marking thenonattainment area of Smyth County alsoensures that the Appalachian Trail, an area frequented bythe public, is included in the nonattainment area.

The EPA agrees withthe State that a rural transport statusmore accurately reflects the ozonenonattainment problem in Smyth County. Documentation supporting Smyth Countyas a rural transport area is contained in the TSD, item#12.

iii. Othertreatment.TheCity of Oshkosh, attainment for COprior to enactment,is hereby designated unclassifiable forCO. (See the TSD, item#13, for documentation supporting this designation.)

9.Procedural requirements.As described above, today's notice promulgates designations, classifications, and boundaries for ozone and CO areas.This section describes the procedural requirements concerning notice- and-comment and judicial review applicable to these actions.

-

a. Designations andboundaries- i. Notice-and-commentrulemaking. Today's notice announces and promulgates the designations that occurred under section 107(d)(1)(C) (designations by operation oflaw at the date ofenactment ofthe 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 ofa 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 ofa designation underparagraph (1), (4)or(5) shall not besubject to the provisions of sections 553 through 557oftitle 5ofthe United States Code(relating to notice and comment), except nothing herein shall be construed as precluding such publicnotice and comment whenever possible.

By its terms, thisprovision exempts the designations announced and promulgated by this notice fromthe notice-and-comment procedures under the Administrative Procedures Act. Through various publicly available letters to the States, EPA described its preliminary views at various pointsin time as to the designation and classification ofareas, 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 bythe CAAA provides:

Itis the intentofCongress that,consistent with thepolicy ofthe Administrative Procedures Act, the Administrator in promulgating anyregulationunder this Act, including aregulation subject to a deadline, shall ensure areasonable period forpublic participation ofat least 30days, except as otherwise expressly proved in section107[d), 172(a), 181(a) and(b), and 186(a) and (b).

TheEPA 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 ofthis document for public comment on any such errors, and, if such errors are brought to EPA's attention, EPA will correct any technical

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

errors made.In addition,ifanyone raises significant new policyissues, EPA will pursue notice-and-comment rulemaking to resolve such issues.This notice willtake effect 60days from the date ofpublication, except tothe extent, ifany, thatEPA determines corrections are necessary in light oferrors elucidated by timely publiccomment.-

ii. Judicial review.The CAAA provide 

### no additionallimits onjudicial review of the designations, includingboundaries. Accordingly, ifa party followsthe appropriate administrative procedures under CAAA, section 307,the party is not barred from challenging EPA's action in this regard through litigation.-

b.Classifications- i.Noticeand comment.Sections 181(a)(3) and 186(a)(2) provide that atthe time EPA publishes thenotice designating ozone and COnonattainment areas:

The Administrator shallpublish anotice announcing the classificationof [suchozone or CO1nonattainment area.The provisions of section 172(a)(1](B) 

### (relating to lack ofnotice 

### and comment andjudicialreview) shall apply to suchclassification.

Section 172(a)(1), which is foundin subpart I ofpartD,deals primarily with classifications that EPAmay make upon promulgating a new orrevised 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 isreferenced by sections 181(a)(3) and section 186(a)(2). provides, inrelevant part:
-

The Administrator shallpublish anotice in theFederal Register announcingeach classification undersubparagraph (A), except theAdministrator shallprovide an opportunity ofatleast30days forwritten comment. Such classification shall notbe subject totheprovisionsofsections553 through 557 oftitle5oftheUnited States Code (concerning notice andcomment) and shall not be subjecttojudicialreview until [specified times).

The EPAinterprets thereference in sections 181(a)(3) and 186(a)(2) to "[tihe provisions ofsection 172(a)(1)(B) (relatingto lack ofnotice andcomment andjudicial review)" toreferto the second sentence in section 172(a)(1)(B), notthe first sentence. As aresult, the provisions ofthefirst sentence requiring a 30-day comment period donot apply to the classifications under section 181(a)(3) or section 186(a)(2), which are the subject ofthis document. TheEPA interprets theparenthetical phrase in sections 181(a)(3) and 186(a)(2) to limit the applicable provisions ofsection 172(a)(1)(B) tothose that eliminate the notice-and-comment requirement, which are found in the second sentence. This reading isconsistent with the fact that thefirst sentence in section 172(a)(1)(B) sets out therequirement for publishing a notice announcing a classification, a requirement that is separately incorporated in sections 181(a)(3) and 186(a)(2). This duplication suggests that thefirst sentence ofsection 172(a)(1)(B) does not apply.

Similarly, EPA takes the position that notice-and-comment rulemaking is not required forany 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 ofan ozone or COnonattainment area is within 5 percent ofthe cut-offfora 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)" forozone, or "by the procedure required under paragraph [section 186(a)(2)1" forCO. As just discussed, those procedures eliminate therequirement fornotice-and-comment rulemaking. -

ii.Judicial review.As noted above, sections 181(a)(3) and 186(a)(2) provide that the provisions concerning judicial review found in section 172(a)(1)(B) apply.Those provisions state that judicial review may occur only after.

[Tihe Administrator takes final action undersubsection (k) or(1)

### ofsection 110 (concerning action on plan submissions) or section 179 (concerning sanctions) with respect to anyplan submissionsrequired by virtue ofsuch classification.

Accordingly, judicial review on the classification decisions [(including the decisions to make, or not to make, reclassifications under the 5percent adjustment provisions ofsection 181(a)(4) and section 186(a)(3)] may be had only at those times. B.PM-10

1. Initial PM-10designations. Previously,EPApublished a Federal Registernotice announcing the designations and classifications forPM10 occurring by operation oflaw upon enactment ofthe CAAA (see56 FR 11101, March 15, 1991). In addition, EPA has published a follow-up notice correcting the boundaries and designations of some areas inlight of comments addressing the March 1991 notice (see 56 FR 37654, August 8, 1991). Both ofthese notices provide a detailed discussion ofthe history and current status ofPM-10 areas nationwide. An abbreviated discussion is provided here.

Generally, EPA adopted a PM-10 SIP development policy "grouping" all areas of the country intothree categories based on theirprobability ofviolating the standards when EPArevised the indicator for particulate matter to PM-lu (see generally 52 FR 24634, July 1, 1987) (revisingparticulate matter indicator fromtotal suspended particulates to PM-10}. The EPA announced the initial groupings for PM-10 in a Federal Register notice published on August 7, 1987 (52FR 29383). The EPA modified the groupings and boundaries in two subsequent Federal Register notices published on March 28, 1989 (54 FR 12620) and October 31, 1990 (55FR 45799).

The CAAA provided designations for PM-10 forthe first time, using EPA's grouping scheme as a starting point. Specifically, the amended law provides that each former Group I area identified in52FR 29383 (August 7, 1987), except to the extent modified before enactment of theCAAA (November 15, 1990), was designated nonattainment for PM-10 [see 107(d)(4)(B)(i) ofthe 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 Iareas listed in the October 1990notice became nonattainment for PM-10 by operation oflawupon enactment ofthe CAAA [the October 31, 1990notice reflects the revisions announced in thenotice published on March 28, 1989 (54FR 12620)]. Any other area (i.e.. Group 11 or 11) violating the PM-10 NAAQS (as determined by 40 CFR part 50, Appendix K)prior to January 1, 1989, also was designated nonattainment for PM-10by operation oflaw upon enactment ofthe CAAA [see section 107(d)(4)[B)(ii) ofthe amended ActI. All other areas were designated unclassifiable for PM-10by operation oflaw upon enactment ofthe CAAA [see section 107(d)(4)(B](iii) of the CAAA]. Finally, all ofthose areas designated nonattainment for PM-10 were classified as moderate by operation oflaw at the time ofthe designation [see section 188(a) of the CAAA). The EPA willbe reclassifying
some ofthese initial PM-10 nonattainment areas from moderate to serious ifEPA determines they cannot practicably attain the PM-10 airquality standards by December 31, 1994 [see 

### section 188(b)(1)].

In the Federal Registernotices published on March 15, 1991 (56 FR 11101) and August 8, 1.991 (56 FR 37654) the EPA applied sections 107(d)(4)(B) and 188(a), and other operative legal provisions, and announced the designations and classifications forPM10.In today's notice, EPAformally codifies thedesignations and classifications for PM-10 announced in these priortwo notices. Further, in a 

### 5

670M5

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

letter dated October2, 1991, Governor Stephens ofthe State ofMontana informed EPAthat 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 concurswith the Governor's comment and has corrected the boundary for Libby. Thus,the codification oftheinitial designations and classifications forPM-10 are as set forth in the table below. Note that today's codification oftheinitial designations for PM-10 [under section 107(d)(4)(B)] in40 CFRpart81 represents final agency action forthe purpose ofsection 307(b) ofthe CAA.

2.

AdditionalPM-10designations. As discussed above, all areasofthec:ountry were designated either nonattainment or unclassifiable forPM-10 by operation of law uponenactment ofthe CAAA pursuant to section 107(d)(4)(B). Section 107(d)(3) ofthe CAAA authorizes the Administrator to redesignate as nonattainment those areas initially designated asunclassifiable forPM-10 [see section 107(d)(3)(A), (B), and (C)]. TheEPA has initiated theredesignation process for some areas. Specifically,in January and February of1991, EPA Regional Administrators provided letters to the Nation's Governors initiating theprocess ofredesignating additional areas as nonattainment for PM-10, as called for in section 107(d)(3)(A) oftheCAAA. In addition, in a Federal Registernotice published on April 22, 1991 (50FR 16274), the EPA 

### identified those PM-10 areas for which EPA had notified the Governors of affected States that an area'sPM-10 designation should be revised to nonattainment. (Theneed to revise the designation for the section in LaSalle County,Illinois, that EPAhad identified in theApril 22, 1991 notice has been rendered moot. In the correction notice for the initialnonattainment areas published in the Federal Register of August 8,1991 (56 FR37654), EPA indicated that this section was designated nonattainment and included as part ofthe initial Oglesby,Illinois, PM-10 nonattainment area.)

In a separate Federal Registernotice, EPA willpropose redesignations for these areas inlight ofcomments received from the affected States. A more detailed discussion about the section 107(d)(3) redesignation process and the actions being proposedwill 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 thenotice-andcomment rulemaking procedures ofthe Administrative Procedures Act (section 107(d)(2)(B) ofthe CAAA).]

As mentioned, EPA Regional Administrators have corresponded with some ofthe Nation's Governors, initiating theprocess toredesignate additional areasofthecountry as nonattainment forPM-10. Insome ofthe responses to these letters, States requested that EPAexpand the boundaries offormer Group Iareas and make the expansion area part of an initialnonattainment area. In the situations where EPA believed there was no legal basis to make such an adjustment, EPAhas indicated that it would treat the State's request as an unsolicitedrequest toredesignate the additional area as nonattainment within themeaning of section 107(d)(3)(D) of theCAAA (56

### FR 37654, 

### August8, 1991). 

### Accordingly,in a separate Federal Register notice, EPAwill determine whether such submittals are complete and, ifso,willpropose to approveor deny the State's redesignations request [see section 107(d)(3)(D) oftheCAAA].

3.Totalsuspended particulates (TSP). Section 107(d)(4)(B) ofthe CAAA 

### provides that thedesignations for particulate matter measured in terms of TSPexisting immediately prior to enactment ofthe CAAA (November 15, 1990)remain in effect. TheTSP designations are toremain in effect until the Administrator determines that the designations are nolonger necessary for implementing themaximum allowable increases in concentrations of particulate matter,measured in terms of TSP,pursuant to section 163(b) [section 107(d)(4)(Bfl.

Thus,by thisnotice, EPA announces that the TSP designations existing before enactment oftheCAAA shall remain in effect fornow. Further,EPA notes that it willreview theneed for these designations andprovidenotice at such timeEPA determines these designations are nolonger necessary for the purpose ofimplementing the increments in section 163(b). C.SulfurDioxide(SO2 

### ) 1.InitialS02 designations. Section 107(d)(1)(C) ofthe CAAA generally provides that those SO2 

### designations existing before enactment of the CAAA were affirmed atenactment by operation oflaw. Thus, the designation ofan SO2

### area existing justprior to enactment ofthe CAAA (November 15, 1990) become the designation ofthe area upon enactment and at thistime. To avoid unnecessary duplication, EPAwill not reprint the codification table for SO2 

### in today's notice.For the status ofSO2 

### areas, readers should refer to the codification tables currently set forth in 40 CFR part 81 (July 1, 1991) and to any subsequent modifications to these SO2 

### tables that have been published in the Federal Register.

2.AdditionalS02 designations. As with the additional PM-10 nonattainment areas, EPAhas initiated the redesignation ofsome S0 2 

### areas pursuant to section 107(d)(3) Qfthe CAAA [section 107(d)(3)(A), (B), and (C)]. In January and February of1991, EPA Regional Administrators provided letters to theNation's Governors initiating the process ofredesignating additional areas as nonattainment for SO2

### , as called for in section 107(d)(3)(A-) ofthe CAAA. In addition, in aFederal Register notice published on April22, 1991 (56FR 16274), EPA identified those SO2 

### areas for which EPA had notified the Governors of affected States that an area's S02 

### designation shouldbe revised to nonattainment.

In a separate Federal Register, EPA will propose designations for these areas inlight ofcomments received from the affected States. Amore detailed discussion about the section 107(d)(3) redesignation process and the actions being proposed for particular areas will be described in thatnotice. D.Lead

1.Background. In 1978,when EPA promulgated the lead NAAQS, the Agency believed that implementation and maintenance of thelead NAAQS shouldbe in accordance with the SIP requirements set forth in section 110of the CAA and not Part D. Therefore, EPA did not designate areas for lead.The Agency believed that section 107 and thePart Drequirementswere intended by Congress toapply only to NAAQS which were set prior to 1977. The CAA, as recently amended in1990, clearly authorizes EPAto designate areas for the lead standard in effect at the date of enactment ofthe 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 ofthe CAAA.

Section 107(d)(5) of the CAAA authorizes EPA to require States to designate areas (orportions thereof) as nonattainment, attainment or unclassifiable with respect to thelead NAAQS in effect as ofthe date of enactment ofthe CAAA. As provided in section 107(d)(5), these lead areas are to be designated pursuant to the procedures outlined in section 107(d)(1)(A) and'(B) ofthe amended

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

CAAA except that certain timeframes in subparagraph (B)have been modified by section 107(d)(5).

Section 107(d)(1)(A) of the amended CAAA permits EPA to require the Governors ofaffected States to submit their recommended designations for the areas EPA seeks designated in a timeframe that EPA deems reasonable. This timeframe, however, canbe no sooner than 120 days, nor later than 1 year, after the date EPA notifies the State ofthe requirement to submit such designations. Section 107(d)(1)(B) ofthe CAAA requires EPA to promulgate these designations no later than 1year after notifying the State of therequirement to designate areas forlead. The EPA may make any modifications deemed necessary to the suggested designations submitted by the State [see generally. section 107(d)(1)(B) ofthe CAAA]. However, no later than 120 days before promulgating a modified area, EPA must notify the affected State and provide an opportunity forthe State to demonstrate 'why any proposed modification is inappropriate. Ifthe Governor of an affected Statefails to submit the required lead designations, inwhole or in part, EPA is required to promulgate the designation that is deemed appropriate forany area (or portion thereof) not designated bythe State.

InJanuary and February 1991, EPA notified the Governors ofaffected States that they shouldproceed to designate as nonattainment those areas that had recorded violations of thelead 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 ofviolating the lead NAAQS, but forwhich existing air quality data are insufficient at this time to designate as attainment ornonattainment [section 107(d)(1)(A)(iii)]. For administrative efficiency reasons, in theJanuary 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 theirdesignations not laterthan 120 days from the date EPA notified them of the requirement to submit such designations. In a Federal Register notice published on April 22, 1991 (56 FR 16274), EPA identified those areas for which EPA had requested designations for lead.

The designation requests submitted by the Governors have created several different situations which require that EPA act on the designations in several actions. The EPAhas termed the EPArequested designations submitted by Governors as "solicited designations" and the designations submitted by Governors on his/her own initiative as "unsolicited designations." The different situations and when EPAintends to formally act on the designations are as follows:

(1)Solicited designation requests submitted within a timeframe sufficient enough forEPA 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 willbe addressed at a laterdate. (As mentioned earlier,EPA must notifythe affected State 120 days prior to the promulgation ofa modified area and provide an opportunity forthe State to demonstrate why any proposedmodification is inappropriate. The EPA notified affected States in May 1991.)

(3) Unsolicited designation requests which EPA may ormay not modify will be addressed at a laterdate. (Although the affected Governors have been notified within the required timeframes that EPA intends tomodify 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'saction.Intoday's notice, EPA is acting on those State submittals which were received byEPA in a timeframe sufficient enough to review and process, and which EPA does not intend to modify. TheEPA is publishing these designations as called for in section 107(d)(2)(A) ofthe 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 andunsolicited designation requests. In thisnotice, EPA is acting only on the solicited portion of the submittals for which EPA has -determinedmodifications are not necessary. The unsolicited portion ofthe submittal will be addressed in a separate notice.

Abrief description ofthe nonattainment and unclassifiable lead
areas is provided below. The legally binding description ofthe nonattainment and unclassifiable area lead boundaries for each affected State is provided in the rulemaking tables at the end ofthis document.

A lead nonattainment area consists of that area which does not meet (orthat 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 ofany area that cannot be classified on the basis ofavailable 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 inwhich the ambient lead monitor(s) recording the violation ofthe lead NAAQS and/or the lead source is located. In some situations, however, a boundary other than the county perimeter may be appropriate. States may seek to alternatively define the lead nonattainment or unclassifiable boundary by using one, ora combination, ofthe following techniques: (1)Qualitative analysis: (2) spatial interpolation ofair monitoring data, or (3) air quality simulation by dispersion modeling. The techniques are described:in more detail in "Procedures for Estimating Probability of Nonattainment ofa PM-10 NAAQS Using Total Suspended Particulate or PM-10 Data," EPA-450/4-86-017, December 1986. Ifa State seeks to alternatively define a lead nonattainment area, EPA recommends that it submit a reasoned and documented justification for the boundary identified.

Finally, the air quality monitoring data and other technical information supporting today's action are available from the respective EPA Regional Office which serves the State where the affected area islocated. The addresses ofthe Regional Offices are listed in the addresses section ofthis document.

### As noted, thisaction is being taken pursuant to section 107(d)(5) ofthe CAAA. Aswith the section 107(d)(4) designations forozone and CO areas, the designations under section 107(d)(5) are exempt from theAdministrative Procedures Act requirements for noticeand-comment rulemaking (5U.S.C. sections 553-557) [see section 107(d)(2)(B) ofthe CAAA]. Nevertheless, as with the ozone and CO designations in today's notice, EPAwill entertain any comments onthese actions that are received byDecember 6, 1991, for the purpose ofcorrecting technical errors. TheEPA's promulgation ofthese designations [forpurposes ofsection 107(d)(2)(A)] willbecome effective on January 6, 1992.This isintended to provide EPA withtime tomake any technical corrections that are appropriate in light ofthe comments.

3.

Additionalactions.TheEPA intends to modify some ofthe suggested designations submittedby States in response to EPA's request to designate areas forlead.As called for in section 107(d)(1)(B)(ii), EPA has notified the affected States that EPAbelieves modification is necessary and is providing them with an opportunity to demonstrate whyEPA'sproposed modification is inappropriate. The EPA will address the modified designations to thesolicited submittals in a separate Federal Register notice, to be published inthe near future.

Additionally, EPA has received unsolicited lead designation requests from some States. At thistime, EPA intends to modify mostofthese requests and, accordingly,has notified the affected States and is providing them with an opportunity to demonstrate why EPA's proposed modification is inappropriate. TheEPA also will address these unsolicited designations in a separate Federal Registernotice, 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 thelead NAAQS will be reviewed. IfEPA 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 ofareas designated as nonattainment, attainment, or unclassifiable forlead. Section 107(d)(1)(B)(iii) ofthe 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 part81. The current 40 CFR part81 designation listings (revised as ofJuly 1, 1990) include by State and NAAQS pollutant, a briefdescription ofareas within the State and their respective designation. TheEPA has modified thisformat in order to betterdescribe 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. TheSO2

### ,NO2

### , and TSPtables are notmodified by today's action butwill 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) ofthe CAAA, all ofthose areas in a State not designated nonattainment forPM-10 were designated unclassifiable for PM-10. Thetables do not specify thePM-10 unclassifiable areas butby implication all those areas not currently designated nonattainment forPM-10 are designated unclassifiable. IV. Other Regulatory Requirements A. Executive Order12291

Under E.O. 12291, EPA is required to judge whether an action is "major" and therefore subject to therequirement ofa regulatory impact analysis. TheAgency has determined that the attainment, nonattainment, and classified area designations and classifications made final today would result in none ofthe significant adverse economic effects set forth in section 1(b) ofthe E.O. as grounds for a finding that an action is "major." TheAgency has, therefore, concluded that this action is not a "major" action under E.O. 12291. This rulewas submitted to the Office of Management and Budget (OMB)for review under thisE.O.

A copy ofthe draft rule as submitted to the OMB, any documents accompanying the draft, any written comments received from other agencies (including OMB), and any written

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

responses to these comments have been included in the Docket. B.RegulatoryFlexibility Act Whenever an agency is required by law to publish a general notice of proposed rulemaking, the Regulatory Flexibility Actof1980 (5 U.S.C. 601-612) generally requires that the agency prepare a Regulatory Flexibility Analysis describing the impact ofthe proposed rule on small entities. Because this rule is not required to be published first as a notice ofproposed rulemaking under section 553 (theAdministrative Procedures Act) or any other law, it is not subject to the requirements of the Regulatory Flexibility Act. List ofSubjects in 40 CFR Part81

Airpollution 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:42U.S.C. 7407,7501-7515, 7601. 2. Section 81.300 is revised toread as follows: §81.300 Scope.

(a) Attainment status designations as approved or designated by the Environmental Protection Agency (EPA) pursuant to section 107 ofthe 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 toEPA 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 orequal to a nominal 10micrometers (PM-A10). Accordingly, area designations forPM-10are included in the lists in subpart Cofthis part.However, the TSParea designations will alsoremain in effect until the Administrator determines that the designations are nolonger necessary for implementing themaximum allowable increases in concentrations of particulate matterpursuant to section 163(b) oftheAct, as explained in paragraph (b) ofthis section.

(b)Designated areas which are listed below as attainment ("Better than national standards") or unclassifiable ("Cannot be classified") for total suspended particulate (TSP), sulfur dioxide (SO2

### ),and nitrogen dioxide (NO 2

### ),represent potential baseline areas or portions ofbaseline areas which are used in determining compliance with maximum allowable increases (increments) in concentrations oftherespective pollutants forthe prevention ofsignificant deterioration of air quality (PSD). With respect to areas identified as "Rest of State" it shouldbe assumed that suchreference comprises a single area designation forPSD baseline area purposes. However, for PM-10, the useofthe term "Rest of State" is aninterim measure to designate asunclassifiable alllocations not originally designated nonattainment forPM-10in accordance with section 107(d)(4)(B) of the Act.

(c) For PM-10areas designated 

### nonattainment,pursuant to section 107(d)(4)(b) by operation oflaw upon enactment ofthe 1990Amendments to the Act, theboundaries are more fully described as follows:

(1)For cities and towns, theboundary ofthe 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 Iareas", in which
case the nonattainment area is defined by the municipal boundary limits as of October 31.1990.

(2) 

### Similarly, forplanning areas, air quality maintenance areas, air basins, and urban growth boundaries the nonattainment area is definedby the entire planning area, air quality maintenance area, air basin, or urban growth boundary as ofNovember 15, 1990, except for areas which were formerly "Group I", in which case the boundary is defined by the entire planning area, air quality maintenance area, airbasin, orurban growth boundary as ofOctober 31, 1990.The foregoing is trueexcept to the extent the planning area, air quality maintenance area, air basin, orurban growth boundary is further defined, e.g., by township, range and/or section. Such geographical descriptors remain a fixed part ofthe nonattainment boundaries irrespective ofwhether they are included in the planning area, air quality maintenance area, airbasin, or urban growth boundary. (3)The boundaries ofPM-10 areas subsequently redesignated pursuant to section 107(d)(3) ofthe Actwill be defined by the city, town,planning area, air qualitymaintenance area, air basin,
or urban growth boundary in effect the date the designation is promulgated.

3.Section 81.301 is amended by revising the tables for "Alabama-O" and "Alabama-CO", and by adding a new table titled "Alabama-Lead" to be inserted in alphabetical order immediately following the tabular entry for "Alabama-SO." to read as follows: §81.301 Alabama.
