SUPPLEMENTARY INFORMATION: Electronic Availability: This document is available as an electronic file on The Federal BulletinBoardat 9 a.m. the day ofpublication in theFederal Register. For the convenience ofthe reader,EPA hasprepared anupdated version ofthe individual State air designation listings that were amended in the Federal Register of November 6, 1991 (56 FR 56694), merged into the 1992 Code of Federal Regulations andfurther amended by this document.The updated files are also available at 9 a.m. theday ofpublication.

In the Federal Register ofNovember 6, 1991 (56 FR 56694), EPA issued a final rule promulgating orannouncing the designations, boundaries, and classifications ofvirtually all ozone and CO areas, all PM-l0 areas, and some lead areas. Under sections 107(d)(2)(B) and (d)(5), 172(a)(1)(B), 181(a)(3), 186(a)(2), and 188(a) of the amended Clean AirAct (CAA), EPA was not required to solicit public comment prior to these promulgations, and in view of the tight time frames imposed under the amended CAA for designations, classifications, and State implementation plan (SIP) submittals, EPA determined that a formal public comment period prior to the promulgations would notbe appropriate. However, in the November 6rule, EPA entertained public comments addressing the technical correctness ofits determinations and significant new policy issues. The EPA indicated that the rule wouldtake effect 60 days after the date ofpublication.

The designations andboundaries promulgated bythe rule took effect on January 6,1992. During the comment period, EPA received comments addressing typographical errors, 40 CFR part 81 table presentations, and technical errors. Independent ofthe comments, EPA identified errors in the 40 CFR part 81 tables. With this issuance, EPAis making corrections to some of the designations, boundaries, and classifications that were promulgated or announced in the rule. These corrections are made under section 110(k)(6) ofthe CAA which provides as follows:

Whenever the Administrator determines that the Administrator's action approving, disapproving, orpromulgating anyplan or

HeinOnline -- 57 Fed. Reg. 56762 1992

### Federal Register / Vol. 57, No. 230 /Monday, November 30, 1992 / Rules and Regulations

plan revision (orpart thereof), area designation, redesignation, classification, or reclassification was inerror, the Administratormay in the samemanner as the approval, disapproval, or promulgation revise such action as appropriate withoutrequiring anyfurther submission from the State. Such determination and the basis thereof shallbe provided to the State and public.

TheEPA interprets this provision to authorize the Agency to make corrections to a promulgated regulation when it is shown to EPA's satisfaction that (1) EPA clearly erred in failing to consider orinappropriately considered information made available to EPA at the time ofthe promulgation, or the information made available at the time ofpromulgation is subsequently demonstrated to have beenclearly inadequate;,and (2) other information persuasively supports a change in the regulation.

Following is a discussion ofthe corrections made to the November 6, 1991 finalrule. Allother comments submitted with respect to theruledrediscussed in a Technical Support Document contained in Air DocketA-90- 42. Comments Relating toTypographical Errors and 40 CFRpart81Table Presentation CarbonMonoxide California

.The AirPollution Control District of San Diego County commented that the boundary description for the San Diego COnonattainment area Is incorrect in. theNovember 6,1991 document. The Area's preenactment boundary and the boundary described bythe State in a December 28, 1990 letter to EPA are identical.However, EPA incorrectly expanded the nonattainment area in the November 6.1991 document. The EPA acknowledges this error.The correct boundary description for theSan Diego
area CO nonattainment areanow appears in the tabular entry ofthis document. 

### Virginia

The Commonwealth ofVirginia questioned why the following areas that
are part ofthe Air Quality Control Regions (AQCR) and are in attainment
are separated out from their respective AQCR's in the November 6,1991 rule: AQCR 047 (National Capital Interstate), AQCR 223 (Hampton Roads Intrastate), and AQCR 225 (State Capital Intrastate).

The explanation is that in therule, EPA followed the same listing format as formerly described in 40CFR 81.348. However,EPA willcombine the areas under their respective AQCR's in a tabular entry ofthis document since the Commonwealth hasrequested this. The 

### Commonwealth should be aware that doing so may affect theprevention of significant deterioration (PSD) baseline study area.

AQCR 223 HamptonRoads was incorrectly listedas "AQCR223 HamptonRoads." The area isnowlisted correctly as "AQCR223Hampton Roads Intrastate"'in the tabular entry ofthis document. Ozone Illinois

The townships "GooseLake" and "Aux Sable".were incorrectly listedas "Gooselake" and "Auxsable" inthe November 6,1991 document.This error is corrected inthis document. North Carolina

The word "Bumcombe" was incorrectly listed as "uncombe" inthe Designated Area column ofthe November 6,1991 document. This error is corrected inthis document. 

### Virginia

The Commonwealth ofVirginia commented that "Hampton Roads Area" is the preferred description for the area thatEPA describes as the "NorfolkVirginiaBeach-Newport News Area." Although EPA's original description is consistent with how other areas are , named, I.e., byusing the Metropolitan Statistical Area (MSA) name, EPA
concurs withthe Commonwealth's request and hasrevised thedescription toread "Norfolk-Virginia BeachNewport News (Hampton Roads)Area."

The Richmond nonattainment area was listed incorrectly asthe "RichmondPetersburg Area." Since Petersburg is in attainment,"the area is now described as the "Richmond Area" inthe tabular entryofthis document.

The Commonwealth alsocommented that the title forAQCR 207 is incorrect. The ozonetable Is corrected by ... changing this title to "AQCR207 Eastern Tennessee - SW VirginiaInterstate." OzoneandCarbonMonoxide Oregon

The Oregon Department of Environmental Quality commentedthat the Salem area was listedin the November 6, 1991 notice asthe "City of Salem" forboth ozone and CO. However, in an earlierletter to EPA (March 15,1991), Governor Roberts recommended thatthese ozone and CO nonattainment boundaries bereaffirmed asthe "Salem Area Transportation Study (SATS)."

Accordingly,the subheading "City of Salem" isreplaced with "Salem Area Transportation Study (SATS)" as requested.

Also,in her March 15, 1991 letterto EPA, the Governorrecommended that the carbon monoxide nonattainment boundary for Medford be established as the "Medford Urban Growth Boundary." The rule incorrectly designated the "Medford-Ashland Urban Growth Boundary." There is no such geographical entity; therefore, the description is corrected in thetabular entry ofthis document toread "Medford Urban Growth Boundary." Virginia

Since Nansemond County is nolonger agovernmental entity,the County Is removed from the tabular entries ofthis document. Nansemond County has been annexed bySuffolk City. EPA-Discovered Errors in40CFR part81 

### Tables PM-10

The EPA inadvertently erred in crafting thePM-10 tables included inthe November 6,1991 final rule.The PM-I0 -tables appropriately identified those _,areas.currently designated as

nonattainment forPM-l0 pursuant to section 107(d)(4)(B) ofthe CAA. However, all ofthe areas in a State not designated nonattainment forPM-l0 were designatedunclassifiable under section 107(d)(4)(B)(iii) ofthe CAA (see 56FR 56705). The PM-10tables published inthe November 6, 1991 document omitted the "Unclassifiable" designation for the "Rest of State" areas 

### not otherwise designated nonattainment. (Ifthe State currently has noPM-10 nonattainment areas,then it follows that the entire State is designatedunclassifiable for PM-iO.) [See section 107(d)(4)1B)(iii).l For administrative efficiency reasons,EPA is notcodifying in40 CFR part81 these State-wide unclassifiable designations.) The40 CFRpart 81 tables appearing in this document correct the oversight.The PM-10 tableheadings are alsomodified byremoving the word "initiaL"

included the classification description in thedesignation column. The error is corrected in this document. Michigan

The tabular listing forAQCR 082 incorrectly omitted "South Bend" in its title.The correct entry "AQCR 082 South Bend-Elkhart-Benton Harbor Interstate" is included in this document. Minnesota

Inthe November 6,1991 rule, portions of threeMinnesota Counties (Benton, Sherburne, and Stearns) that make up the City ofSt.Cloud were listed as "Unclassifiable/Attainment." However, the table should have included a footnote explaining that the area is in the process ofbeing redesignated to attainment forCO, and until such time as theredesignation approval is finalized the listing will have no force or effect (seethe footnote added to the Minnesota

- Carbon Monoxide table for clarification). WestVirginia

A footnote explaining the attainment status ofBrooke and Hancock Counties was accidentally left out ofthe November 6, 1991 final rule. The footnote is included in the tabular section of this document. Comments Relating toTechnical Errors Lead Georgia

The Georgia Environmental Protection Division (onbehalf ofthe State of Georgia) submitted comments requesting a revision to thelead nonattainment boundary forMuscogee County. The State proposed to change the boundary ofthe lead nonattainment area from the entire County to a circle with a radius of2.3 kilometers, with the GNB, Inc., lead smelting and battery production facility in the center.Georgia submitted dispersion modeling demonstrating that this boundary.is more appropriate than the entire county.

In the preamble to the November 6, 1991 rule, EPA described its policy for determining the boundary of a lead nonattainment area. The EPA indicated that the definition ofnonattainment area in section 107(d)(1)(A)(i) of the CAA is the controlling legal standard. TheEPA noted that generally it had recommended that the lead nonattainment boundary be defined by the county perimeter for the county in ;vhich the ambient lead monitor(s) recording the violation ofthe lead NAAQS and/or lead source is located. The EPA also noted that there maybe situations when a boundary other than the county perimeter may be appropriate: States may seek toalternatively define the lead nonattainment or unclassifiable boundary by using one, or a combination, of the 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 ofNonattainment ofa PM-10 NAAQS UsingTotal Suspended Particulate orPM-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 (56FR 56707).

Also in the preamble to the November 6, 1991 rulemaking, EPA indicated that it would entertain comments on the technical corrections of its determinations and significant new policy issues (56 FR 56694). The dispersion modeling and associated documents submitted by Georgia reflect
a reasoned and documented justification fordefining the nonattainment boundary to include only the area within a 2.3- kilometerradius of the GNB facility. The State has demonstrated that the 2.3- kilometerboundary includes both the portion of the county that does not meet the lead NAAQS and the source ofthe nonattainment problem [see section 107(d)(1)(A)(i) of the CAA]. Further, Georgia's submittal called into question the technical correctness of-theearlier boundary determination for this area., For these reasons, relying on its authority under section 110(k)(6) of the CAA, EPA is modifying the lead nonattainment boundary for Muscogee County, Georgia, from the entire county to that part of the county which includes
a circle with a radius of 2.3-kilometers with the GNB lead smelting and battery production facility in the center.

As provided in section 191(a), thePart D SIP for that portion ofthe County remaining nonattainment for lead will be due 18 months from the effective date of the'nonattainment designation for that area (i.e.,18 months from January 6, 1992, the effective date of the November 6, 1991 rule). Ozone Michigan

As described in the November 6, 1991 final rule, EPA generally relied on the years 1987-1989 for ozone designations and classifications. However, in some cases, EPA used complete 1988-1990 data ifthey were quality assured and publicly available in the Aerometric " Information Retrieval System (AIRS) by February 13, 1991, and the State requested a lower classification for the nonattainment area. In the November 6, 1991 final rule, EPA announced the classification ofMuskegon County, Michigan, as serious based on 1987-1989 

### data.Based on correspondence with the State and upon reviewing therecord, EPA has determined that the 1988-1990
ozone concentrations data for Muskegon County, Michigan, were submitted before February 13, 1991, and justify a moderate classification based on the design value. In addition, the State of Michigan requested that EPA classify the area as moderate. Thus, Muskegon meets EPA's criteria forclassification as a moderate area. Washington

In a letter from Governor Booth Gardner to the Administrator, dated December 18, 1991. Washington State presented a case that the Puget Sound Region "experiences unique geographic and urbanization patterns and climatological conditions" and that a rigorous evaluation to establish more appropriate boundaries than those proposed is warranted. The State submitted a specific boundary recommendation on January 17,1992, in
a letter from the Assistant Director of the Washington Department ofEcology to the Regional Administrator ofRegion X. This letter contains the technical details andjustification forthe State's boundary recommendation.

In light of this information, EPA is correcting the Seattle ozone nonattainment area boundary under section 110(k)(6) ofthe CAA as amended. In amending the nonattainment boundary, the State relied on a variety ofinformation, including air quality data, point source information,land use patterns and projections, climatic and meteorological data, ozonegeneration and transport dynamics, and population density data. The State obtained population density information from the Puget Sound Regional Council and compiled it into
zones which are nearly identical to U.S. Census tracts. The population in each tract was ranked by density and then accumulated and mapped by percentages oftotal population. The population data were mapped into a band which represents 95 percent of the population in the three-county area. This information was compiled for 1990 as well as projection years of2010 and 2020. The map encompassing 95 percent of the three-county population for each
was the preliminary step in establishing the boundary. The State then compared the map with the other criteria. Land
uses such as major industrial sites, cities, and transportation corridors were reviewed, and boundaries were expanded as necessary to assure inclusion. Finally, the boundary was expanded further to account for ozone

transport. Meteorological conditions and a limited amount ofspecial study ozone data were considered in this final adjustment. The final boundary recommendation by the State covers all the urbanized area as defined by the U.S.Census Bureau.The boundary covers all ofPierce County, nearly all of King County, and the urbanized portion ofSnohomish County. The boundary contains greater than 95percent ofthe current andprojected population, virtually all ofthe sources ofoxides of nitrogen and volatile organiccompounds in the three-county region,the monitoring sites, and areas that are likely to receive transported ozone. In this document,EPA is correcting the boundaries to conform to the State's recommendation. Wisconsin

As described in theNovember 6, 1991 final rule, EPA generally relied on the years 1987-1989 for ozone designations and classifications. However, in some cases, EPA used complete 1988-1990 data iftheywere quality assured and publicly available in AIRSby February 13, 1991 and theState requested a lower classification for the nonattainment area. In theNovember 6, 1991 final rule, EPA announced the classification of Sheboygan County as serious based on 1987-1989 data.Based on correspondence with the State, and upon reviewing therecord, EPA has determined that the 1988-1990 ozone concentration data for Sheboygan County were submitted before February 13, 1991 andjustify a moderate classification based on the design value.

Inaddition, theState ofWisconsin requested that EPA classify the area as moderate. Therefore, Sheboygan County meets EPA's criteria for classification as a moderate area. In this document, EPA is correcting the classification to moderate. CarbonMonoxide Massachusetts

Several commenters questioned the use of 1986 data to classify theBoston nonattainment area as Moderate, and argued that the area should be treated as attainment onthe basis of1988-1989 data. EPA is continuing toreview these comments. As a result,EPA is not, in this notice, revising the designation or classification ofthe Boston area, and EPA intends to respond to the commenters in a future action. OtherActions Ozone NewYork

Upon enactment ofthe CAA Amendments of 1990,the existing nonattainment areas, including the New York-New Jersey-Long Island Consolidated Metropolitan Statistical Area (NYC CMSA), were reaffirmed as nonattainment for ozone by operation of law.In addition, onNovember 15, 1990, the NYC CMSA was classified as a severe ozone area with 17 years to attain the standard based on its calculated ozone design value of0.201 part permillion. Section 107(d)(4)(A)(iv)- (v) of the CAA requires that the boundary for a serious, severe, or extreme area become the entire CMSA unless the Governor of therespective State notifies EPA that moretime is needed to study the boundaries. A finding concluding that a smaller boundary is more appropriate had to be completed andEPA had to concur in the findingbyJanuary 15, 1992, or the New York City nonattainment area would automatically become the entire CMSA. OnDecember 28, 1990, New York State formally requested additional time to study the appropriate boundary forthe NYC CMSA as it relates to the air quality designations for the Counties of Orange andPutnam. In a March 21, 1991 letterand in a June 4, 1991 letter,New York State again requested additional time to evaluate the boundaries of Orange andPutnam Counties. On January 15, 1992, New York State's Department ofEnvironmental Conservation (NYSDEC) formally submitted a study (NYSDEC had previously submitted drafts ofthe study) to the EPA Region 11Administrator discussing the designations and classifications ofOrange and Putnam Counties. New York State made the following boundary recommendations in the studybased on-population densities, population growth, and airquality in the area:

Orange County-Towns ofBlooming Grove, Chester, Highlands, Monroe, Tuxedo, Warwick, and Woodbury remain with the New York City nonattainment area and are classified as severe-17.

Orange County-Other 16 towns and cities are designated as attainment.

PutnamCounty- Entire County is designated as nonattainment and classified asmarginal.

The primary reason for excluding portions of Orange County and all of Putnam County from theNYC CMSA was that the excluded areas do not contribute significantlyto ozone violations in the NYC CMSA. The State reviewed population growth in Orange and Putnam Counties forthe last 10 years and found that the seven Orange County towns listed above experienced high population growth rates ofnearly 30percent. These seven towns are located in the southeastern portion of the County immediately north of Rockland County along the Hudson Valley, and they are closest to the rest oftheCMSA. By way ofcontrast, population grew much slower in the remaining portions ofOrange County and in all ofPutnam County. The towns in Putnam County experienced only a 3- percent population growth.

The study also examined the attainment status ofthese and surrounding areas. Although there isno permanent ozone monitoring stationin either Orange orPutnam County, a properly sited, temporary EPA monitoring stationinWest Point, Orange County,measured ozone concentrations in the severe classification. These violations are believed to be theresult oftransported ozone from the NYC CMSA. Based on the highpopulation growth rate in the southern part ofOrange County, its proximity to therest ofthe NYC CMSA severe nonattainment area, and the measured violations at theWest Point monitor,New York State recommended that the southern seven towns ofOrange County be designated nonattainment and classified as severe, thusbeing part ofthe NYC CMSA nonattainment area.

Similarly,based onthe small population growth in thenorthern portion ofOrange County, New York State recommended that the northern portion ofOrange County be excluded from the NYC CMSA anddesignated attainment. The State recommended that Putnam County be grouped with Dutchess County and classified as a marginal nonattainment area.The State concluded that the PutnamCounty classification shouldbe marginal, based onthe fact that the County will be surrounded bynonattainment areas, most ofwhich are classified severe, and that the population density ofPutnam County (362people per square mile) is comparable to Dutchess County (321 people per square mile), a county immediately to the north ofPutnam County which is classified as a marginal nonattainment area.

It should be noted that New York is located entirely within the Northeast Ozone Transport Region, and all areas ofthe State are subject to certain controls regardless oftheir attainment status. On January 15,1992, the Administrator agreed with the State's findingthat northern Orange County and Putnam County do notsignificantly contribute to ozoneviolations in the NYC CMSA nonattainment area. In a January 15,1992, letterto the NYSDEC Commissioner, theAdministrator

### By letterto theU.S. EPA Administrator dated May 21. 1992, a commenter objected to the exclusion from the NYC CSMA nonattainment
area ofthe northeastern portion of Orange County on grounds that the totsa population, population density, prior population growth, commuting patterns, and growth projection indicate that
sources in thisarea do contribute to the nonattaimnent problem. By letterto the U.S. EPA General Counsel datedJuly23. 1992, this commenter extended its objection to the exclusion from the NYC CSMA nonattainment aea of all of Orange County as well as Putnam County.

Due to thefacs that these comments were submitted recently, andthatEPA mustcoordinate its analysiswith the State.EPAhas not, to date,been able to complete itsevaluation of these comments. Accordingly, EPAplans to proceed withthe.designation and classification ofOrange sad Putnam Counties as.described above; however.

At that time, the State and EPA were reviewingwhether toconfirm orrevise that designation, andEPA committed to publish a subsequent Federal Register document tothat effect. During the designation process,EPA received numerous comments both in support of expanding theexisting boundary andIn opposition toexpansion. The nature of this Issue,coupled with themany comments received from thepublic. madeit apparent to EPA that more information was neededhr orderto adequately define theboundaries.
