40 CFR Parts 52and 81 [OH92-1 &OH79-3; FRL-5458-8] Approval and Promulgation of Implementation Plans and Designation ofAreas forAir Quality Planning Purposes; Ohio

AGENCY: Environmental Protection Agency (USEPA). ACTION: Final rule.

SUMMARY: The USEPA is determining that the Cleveland -Akron-Lorain (CAL)

ozone nonattainment area (which includes the Counties ofAshtabula, Cuyahoga, Geauga, Lake, Lorain, Medina, Portage and Summit) has attained the public health-based National Ambient Air Quality Standard (NAAQS) for ozone. This determination is based upon three years ofcomplete, quality-assured, ambient air monitoring data for the 1993 to 1995 ozone seasons that demonstrate that the ozone NAAQS has been attained in each ofthese areas. On the basis ofthis determination, USEPA is also determining that certain reasonable-further-progress (RFP) and attainment demonstration requirements, alongwith certain otherrelated requirements, ofPart D ofTitle 1ofthe Clean Air Act (CAA) are not applicable to the Cleveland -Akron-Lorain area.

In another part ofthisrulemaking, the USEPA is approving the Ohio Environmental Protection Agency (OEPA)request to revise the official designation ofthe Cleveland-AkronLorain (CAL) area as an area that is meeting the ozone air quality standard. The USEPA is also approving the CAL

area maintenance plan as a revision to Ohio's State Implementation Plan (SIP) for ozone. The purpose ofthe maintenance plan is to provide for continued good ozone air quality levels in the area over the next 10 years. EFFECTIVE DATE: This final rule is effective on May 7, 1996. ADDRESSES: Copies ofthe determination ofattainment, redesignation requests, public comments on the rulemaking, and other materials relating to this rulemaking are available for inspection at the following address: (It is recommended that you telephone William Jones at (312) 886-6058, before visiting the Region 5 Office.)

SUPPLEMENTARY INFORMATION:
Determination ofAttainment

I. Background Subpart 2 ofPart D ofTitle Iofthe CAA contains various air quality planning and state implementation plan (SIP) submission requirements for ozone nonattainment areas. The USEPA believes it is reasonable to interpret provisions regarding RFP and attainment demonstrations, alongwith certain other related provisions, so as not to require SIP submissions if an
ozone nonattainment area subject to those requirements is monitoring attainment ofthe ozone standard (i.e., attainment ofthe NAAQS demonstrated with three consecutive years of complete, quality-assured, air quality monitoring data). As described below, USEPA has previously interpreted the general provisions of subpart 1ofpart D ofTitle I (sections 171 and 172) so as not to require the submission ofSIP revisions concerning RFP, attainment demonstrations, or contingency

measures. As explained in a memorandum from John S. Seitz, Director, Office ofAir Quality Planning and Standards, entitled "Reasonable Further Progress, Attainment Demonstration, and Related Requirements for Ozone Nonattainment Areas Meeting the Ozone National Ambient Air Quality Standard," dated May 10, 1995, USEPA believes itis appropriate to interpret the more specific RFP, attainment demonstration and related provisions of subpart 2 in the same manner.

First, with respect to RFP, section 171(1) ofthe CAA states that, for purposes ofpart D ofTitle I, RFP

means such annual incremental reductions in emissions ofthe relevant air pollutant as arerequired by this part

or may reasonably be required by the Administrator for the purpose of ensuring attainment ofthe applicable NAAQS by the applicable date." Thus, whether dealing with the general RFP requirement ofsection 172(c)(2), or the

more specific RFP requirements of subpart 2 for classified ozone nonattainment areas (such as the 15 percent plan requirement of section 182(b)(1)), the stated purpose ofRFP is to ensure attainment bythe applicable attainment date.' If an area has in fact

1USEPA notes thatparagraph (1)ofsubsection 182(b)is entitled "PLAN PROVISIONS FOR REASONABLE FURTHER PROGRESS" and that subparagraph (B)ofparagraph 182(c)(2) isentitled "REASONABLE FURTHER PROGRESS DEMONSTRATION," thereby making itclear that attained the standard, the stated purpose ofthe RFP requirement will have already been fulfilled and USEPA does not believe that the area need submit revisions providing for the further emission reductions described in the RFP provisions of section 182(b)(1).

The USEPA notes that it took this view with respect to the general RFP requirement ofsection 172(c)(2) in the General Preamble for the Interpretation ofTitle I ofthe Clean Air Act Amendments of 1990 (57 FR 13498 (April 16, 1992)), and it is now extending that interpretation to the specific provisions of subpart 2. In the General Preamble, USEPA stated, in the context ofa discussion ofthe requirements applicable to the evaluation ofrequests to redesignate nonattainment areas to attainment, that the "requirements for RFP will not apply in evaluating a request for redesignation to attainment since, at a minimum, the air quality data for the

area must show that the area has already attained. Showing that the State will make RFP towards attainment will, therefore, have no meaning at that point." (See 57 FR at 13564)2 Second, with respect to the attainment demonstration requirements ofSection 182(b)(1), an analogous rationale leads to the same result. Section 182(b)(1) requires that the plan provide for "such specific annual reductions in emissions * * * as necessary to attain the national primary ambient air quality standard bythe attainment date applicable under this Act." As with the RFP requirements, if

an area has in fact monitored attainment ofthe standard, USEPAbelieves there is

no need for an area to make a further submission containing additional

measures to achieve attainment. This is also consistent with the interpretation of certain section 172(c) requirements provided by USEPA in the General Preamble to Title I. As USEPA stated in the Preamble, no othermeasures to provide for attainment would be needed by areas seeking redesignation to attainment since "attainment will have been reached." (57 FR at 13564; see also September 1992 Calcagni memorandum

both the 15 percentplan requirement ofsection 182(b)(1) and the 3 percent peryear requirement of section 182(c)(2) are specific varieties ofRFP requirements.

2See also "Procedures for Processing Requests to Redesignate Areas to Attainment," from John Calcagni, Director, Air QualityManagement Division, toRegional Air Division Directors, September 4, 1992, atpage 6 (stating thatthe "requirements forreasonable further progress willnot apply for redesignations because they only have meaning for areas not attaining the standard") (hereinafterreferred to as "September 1992 Calcagni memorandum").

at page 6). Upon attainment ofthe NAAQS, the focus ofstate planning efforts shifts to the maintenance ofthe NAAQS and the development ofa maintenance plan under Section 175A.

Similar reasoning applies to other related provisions of subpart 2. The first ofthese are the contingency measure requirements of section 172(c)(9) ofthe Act. The USEPA has previously interpreted the contingency measure requirement of section 172(c)(9) as no longer being applicable once an area has attained the standard since those "contingency measures are directed at ensuring RFP and attainment by the applicable date." (57FR at 13564; see also September 1992 Calcagni memorandum atpage 6).

The State must continue to operate an appropriate air quality monitoring network, in accordance with 40 CFR part 58, to verify the attainment status ofthe area. The air quality datarelied upon to determine that the area is attaining the ozone standard must be consistent with 40 CFR part 58 requirements and other relevant USEPA guidance and recorded in USEPA'sAerometric Information Retrieval System (AIRS).

The determinations made in this notice do not shield an area from future USEPA action to require emissions reductions from sources in the area where there is evidence, such as photochemical grid modeling, showing that emissions from sources in the area contribute significantly to nonattainment in, or interfere with maintenance by, any other States with respect to the NAAQS (see section 110(a)(2)(D)). The USEPA has authority under sections 110(a)(2)(A) and 110(a)(2)(D) ofthe Act to require such emission reductions if necessary and appropriate to deal with transport situations. Analysis ofAir Quality Data

The USEPA has reviewed the ambient air monitoring data for ozone (consistent with the requirements contained in 40 CFR part 58 and recorded in AIRS) for the Cleveland-Akron-Lorain ozone nonattainment area in Ohio from the 1992 through 1995 ozone seasons. The following ozone exceedances were recorded for the period from 1993 to 1995 (and the average number of expected exceedances for this three-year period is also presented):

Cleveland -Akron-Lorain: Medina County, 6364 Deerview Lane (1994)- 0.127 parts per million (ppm); average expected exceedances: 0.3. Cuyahoga County, 891 E. 152 St. (1993)-0.126 ppm, (1994) 0.127 ppm and 0.125 ppm; average expected exceedances: 1.0. Data 

### for 1995 shows no new exceedances of the ozone NAAQS were monitored in the Cleveland-Akron-Lorain area.

On the basis ofthis review, USEPA determines thatthe area has attained the

ozone standard during the 1993-95 period, which is the most recent threeyear time period ofair quality monitoring data, and therefore are not required to submit a 15% emissions reduction plan, attainment demonstration, and a section 172(c)(9) contingency measure plan. See theJune 29, 1995, proposed rulemaking published in the FederalRegister at 60 FR 31433.
Public Comment/USEPA Response

These arethe comments and responses that relate to the determination ofattainment forthe Cleveland -Akron-Lorain area. Comments thatwere received in support ofthedetermination arenot summarized below; only the adverse comments are summarized and responses areprovided to these comments. No further action will be taken on the determination of attainment forthe Dayton and Toledo
areas since those areas have already been redesignated to attainment. In a later part ofthis rulemakingcomments and responses areprovided on the

ozone redesignation request forthe CAL

area. Because ofthepotential for overlap ofcomments received on the issue ofthe determination ofattainment and the redesignation, USEPA hereby incorporates by reference the responses contained in the section below on redesignation tothe extent thatthey bear on the issues involved in the determination ofattainment, and vice
versa. To the extent that comments can be construed to bear on both rulemaking actions, responses should be construed to pertain to both. (1)Comment:The determination action has been inappropriately segregated from the section 110(a)(2)(D) petition submitted by the StateofNew York which requested theFederal government to assess the implementation plans ofupwind states to determine their contribution to nonattainment in the State ofNew York. Regional Oxidant Modeling indicates that areas to thewest ofthe State ofNew York, including the StateofOhio, contribute to violations ofthe ozone NAAQS in the northeast United States, including the StateofNew York. Therefore these areas should continue to meet the statutory reasonable further progress requirements setforth in the Clean Air Act, at leastuntil the State of New York's section 110(a)(2)(D) request has been acted on. (1) Response:The issue oftransported emissions is not relevant to this rulemaking action. The purpose ofthe requirements of section 182(b)(1) concerning reasonable furtherprogress and attainment demonstration and the contingency measure requirements of section 172(c)(9) as they apply to CAL is not to address emissions from that

area that may cause or contribute to air quality problems in downwind areas. The purpose ofthose requirements as they apply to CAL is to achieve attainment ofthe standard in that area. The issue oftransported emissions is dealt with by other provisions ofthe Act, provisions that are not the subject ofthis rulemaking action. USEPA has authority, and the state has an obligation, under section 110(a)(2)(A) (in the case ofintrastate areas) and section 110(a)(2)(D) (in the case of interstate areas), to address transported emissions from upwind areas that significantly contribute to air quality problems in downwind areas. The determination being made in this rulemaking is that, as CALhas attained the ozone standard, certain additional Actrequirements whose purpose is to achieve attainment in the area do not apply to them. That determination does notmean that the area might not have to achieve additional reductions pursuant to otherprovisions ofthe Act ifitis determined in the future that such reductions are necessary to deal with transport from the CAL area to downwind areas.

Currently, the issue oftransported

ozone and ozone precursors is being addressed by the Ozone Transport Assessment Group (OTAG) which is composed ofIndustry, Environmental Groups, Federal Government, State Governments (including the State of Ohio), and Local Governments from the Midwest and Eastern Regions. OTAGis performing ozone modeling to determine how ozone transport can be addressed on aregional basis. After this assessment is completed, The United States Environmental Protection Agency (USEPA) anticipates using its authority under sections 110(a)(2)(A) and 110(a)(2)(D) ofthe Act to require emissions reductions where appropriate based on this assessment and any other relevant information. (2) Comment:The determination of attainment fails to meet the purpose, intent and spirit ofthe Clean Air Act by notprotecting and enhancing the quality ofthe Nation's air resources so
as to promote the public health and welfare and the productive capacity of its population. The ozone standard has been shown to be inadequate to protect public health. The American Lung

Association has provided ample evidence and new studies continue to confirm this. It is very clear to many people living here that the air is polluted and adversely affecting people's health. Furthermore, no one has demonstrated that the bad air and high pollution levels in Ohio's nonattainment areas are not adversely affecting the health ofthose downwind.

(2) Response:The determination of attainment is based on ozone monitoring data collected in the Cleveland -Akron-Lorain area. These data continue to show that the area has attained the standard. In a separate part ofthisrulemaking the ozone redesignation request is discussed. This request contains a maintenance plan which willprovide for continued maintenance ofthe standard into the future. The maintenance plan is unaffected by the determination of attainment that finds that the 15% plan, attainment demonstration, and section 172(c)(9) contingency measures are no longer required.

USEPA is also reviewing the current

ozone standard to see whether it should be revised in order to better protect the public health. Until the current NAAQS is revised, the current NAAQS of .12 parts per million is the appropriate standard against which to assess plans and measure attainment.

(3) Comment:The piecemeal approach which USEPA is taking to

ozone attainment and redesignation is promotingbacksliding and encouraging doing the least possible to protect public health and actually clean up the air. A holistic approach to solving environmental problems is always needed. This is no exception. Reviewing emissions inventories in one rulemaking, NOx in another, the SIP in another, Reasonable Further Progress in another, transportation modeling in another, etc. is a methodology which effectively puts blinders on and prevents complete analysis of interdependence aspects. Furthermore this piecemeal approach is an out-ofsequence, illogical process.

USEPA must first determine if attainment has been reached in accordance with the Clean Air Act's redesignation criteria given in section 107. Without ascertaining that attainment has actually been reached it is premature to alleviate the requirements for further controls or Reasonable Further Progress. It appears that USEPA is only applying the first redesignation requirement that the area has attained the NAAQS and ignoring the otherrequirements for redesignation and proceeding to relax the standards. (3) Response:Nothing requires that all ofthe SIPrevisions submitted by the State be reviewed together. The CAA has differing submittal dates for the SIPs and requires USEPA to act on each within a specific time period ofits submittal. This would probably not allow adequate time for USEPA to process all ofthe submittals atonce, given that some ofthe submittals were submitted years apart from each other. Where possible USEPA has sought to consolidate responses to submittals but the CAA is not always conducive to this approach. The determination of attainment is not the same as a redesignation to attainment, and therefore the requirements of section 107, which apply to redesignations to attainment are not applicable. See also the response to comments below. The determination ofattainment is only based on the area's ozone monitoring data. USEPA has decided to address the determination ofattainment and the State's ozone redesignation request for Cleveland -Akron-Lorain together in this Federal Register action. This rulemaking does not circumvent the redesignation requirements. See the discussion in the redesignation rulemaking, below, and in USEPA's Responses to Comments in its Determination ofAttainment ofOzone Standard for Salt Lake and Davis Counties, Utah 60 FR36723 (July 18, 1995). USEPA in this portion ofthe rulemaking, its determination of attainment, is simply making afactual determination that since CAL is attaining the standard, certain provisions ofthe CAA, whose express purpose is to achieve attainment ofthe standard, do not require SIP revisions. In the redesignation portion ofthis rulemaking, USEPA explains its basis for concluding that CALhas met the requirements of section 107 for redesignation to attainment.

With respect to the determination of attainment, USEPA set forth in the June 29, 1995 notices on CAL its basis for interpreting certain CAA requirements

as inapplicable to an area that is attaining the ozone standard.

This interpretation is consistent with USEPA's General Preamble for the Implementation ofTitle I ofthe Clean Air Act Amendments of 1990 ("General Preamble"), 57 FR 13,498 (April 16, 1992), which directly addressed requirements for redesignations. Id. at 13,561-64. USEPA interpreted the general reasonable further progress requirement and contingency measures
as not applying to redesignation requests because an area musthave attained the standard before it could be redesignated to attainment, making reasonable further progress and contingency measures, unnecessary.

USEPA's May 10 memorandum set forth USEPA's interpretation ofthe requirements ofCAA sections 172(c)(9) and 182(b)(1)(A), with respect to ozone nonattainment areas that have achieved the ozone NAAQS. USEPA explained that because the purpose ofthose requirements has already been fulfilled for areas that have attained the standard, the requirements do not apply to those

areas for as long as they stay in attainment. It further explained that this interpretation is consistent with USEPA's interpretation ofthe general reasonable further progress requirements and section 172(c)(9) contingency measure requirements with respect to redesignation requests as set forth in its General Preamble, and with related USEPA guidance on the procedures to be used when USEPA is processing redesignation requests.

USEPA has concluded that Congress included the 15 percent plan as a specification of "reasonable further progress". Section 182(b)(1) is entitled "Plan provisions forreasonable further progress." The heading's reference to "reasonable further progress" indicates Congress' overall intentin enacting the provision. The term "reasonable further progress" is defined as "such annual incremental reductions in emissions of the relevant air pollutant as are required by this part or may reasonably be required by (USEPA)for the purpose of ensuring attainment ofthe applicable (NAAQS) by the applicable date." 42 U.S.C. section 7501(1). This definition applies for "the purposes of* * * part" DofTitle Iofthe CAA, which includes section 182(b). Id. Thus, the term "reasonable further progress" requires only such reductions in emissions as are necessary to attain the NAAQS bythe attainment date and no more. 42 U.S.C. section 7501(1). Accordingly, USEPA has interpreted section 182(b)(1)(A)(I) consistent with the statutory definition of "reasonable furtherprogress" and with section 182(b)(1)(A)(I)'s express purpose ofassuring progress to bring violating areas into attainment. Ifan
area has in fact attained the standard, the stated purpose ofthe RFP requirement willhave already been fulfilled and USEPA does not believe that the area need submit revisions providing forthe further emissions reductions described in section 182(b)(1).

The legislative history expressly supports USEPA's interpretation of section 182(b)(1)(A)(I). In describing the 15 percent plan, the House Report stated: 

## 20460

HeinOnline -- 61 Fed. Reg. 20460 1996

### Federal Register / Vol. 61, No. 89 / Tuesday, May 7, 1996 / Rules and Regulations

The emissions reductions called for in this subsection* * * provide a concrete translation ofhow much an area mustdo to achieve "reasonable further progress" toward attainment ofthe standards, as required in section 172 and defined in section 171. Areas that fail, as determined by USEPA, to achieve reasonable furtherprogress are in violation of the Act.
H.R. Rep. no. 490, 101st Cong., 2d Sess., pt. 1(1990) at 236. Thus, Congress contemplated that the requirements of section 182(b)(1)(A)(I) were simply a specification ofthe more general reasonable furtherprogress requirements ofthe Act, with the same goals and definition.

Moreover, USEPA's interpretation of the requirements ofsection 182(b)(1)(A)(I) is consistent with its interpretation ofthe general reasonable further progress requirements ofCAA section 172.

USEPA has also determined that section 172 (c)(9), 42 U.S.C. section 7502(c)(9) does notrequire a contingency measures plan for an area such as CAL, which has attained the standard. The contingency measures plan is required for an area which "fails to make reasonable furtherprogress, or to attain the (NAAQS) by the attainment date * * *" 42 U.S.C. section 7502(c)(9). If, as USEPAhas determined with respect to CAL, an area has already attained the standard, then by definition such an area is not one to which contingency measures apply. There simply is no failure to attain or make progress for which additional measures need be contingent. However, as with section 182(b)(1)(A)(I), USEPA interprets section 172(c)(9)'s requirements to be applicable to areas that lapse back into violation prior to redesignation, and which therefore need additional progress toward attainment. Moreover, USEPA's interpretation of 172(c)(9) is consistent with its interpretation ofthese requirements in the context ofredesignation requests. 57 FR 13564. USEPA's interpretation also vindicates the policy objective of reducing the burden on states and

sources ofadopting and implementing additional control measures that are not necessary to attain the standard.

(4) Comment:The number of "close calls" and the use ofvoluntary measures to reduce ozone raises real questions about the overall air quality. Modeling would answer some ofthese questions and give a truer picture of what the air is really like. Some initial analysis of the weather patterns in 1995 indicates that they may be similar to 1988, a supposedly "unusually hot, dry summer" when numerous exceedances

were recorded. In fact, the weather in Ohio in 1988 or thus far in 1995 is not allthat unusual. Even higher temperature have been recorded. It can be expected that there will be more exceedances, unless there are reductions in ozone precursor emissions.

USEPA policy (September 4, 1992, procedures for processingrequests to redesignate areas to attainment, from John Calcagni) states that data from the monitors be from areas ofhighest concentration and that modeling may be necessary to determine the representativeness ofthe monitor data. (4)Response:While voluntary

measures were used in Cleveland during the summer of 1995 to involve the community in keeping their air clean, the Ohio Environmental Protection Agency (OEPA) did not claim that this

measure was responsible for the Cleveland area attaining the NAAQS. Ohio's request claimed that the improvement in air quality was due to permanent and enforceable measures, namely the Federal Motor Vehicle Emissions Control Program and the Federal fuel volatility requirements that reduced the emissions from gasoline. In addition, the basic automobile inspection and maintenance program, required as a part ofthe carbon monoxide SIP, would also have provided volatile organic compound (VOC), and oxide ofnitrogen (NOx) emissions reductions in the area, as a side benefit. These measures resulted in the area's VOC emissions decreasing by about 14percent from 1990to 1994, enabling the area to reach attainment of the ozone NAAQS.

USEPA policy on the determination of attainment is provided in aMay 10, 1995, memorandum from John S. Seitz, Director ofthe Office ofAir Quality Planning and Standards. This memorandum sets forth USEPA's interpretation ofcertain requirements of subpart 2 ofpart D oftitle I ofthe Clean Air Act as they relate to ozone nonattainment areas that are meeting the ozone NAAQS. The USEPAbelieves it is reasonable to interpret provisions regarding RFP and attainment demonstrations, alongwith the related requirements, so as not to require SIP submissions if an ozone nonattainment

area subject to those requirements is in fact attaining the ozone standard (i.e., attainment ofthe NAAQS is demonstrated with 3 consecutive years ofcomplete, quality-assured air quality monitoring data). The USEPA has previously interpreted the general provisions of subpart 1 ofpart D oftitle I (section 171 and 172) so as not to require the submissions ofSIP revisions concerning RFP, attainment demonstrations, or contingency measures, and USEPA believes it is appropriate to interpret the ozonespecific provisions of subpart 2 in the

same manner. This is further discussed under section I covering the background

on the determination ofattainment.

The determination of attainment is based only on ozone monitoring data for the area. The data for atleast the last four years show that the area has achieved attainment. We believe that the monitoring data is adequate and representative ofthe area and that modeling is not necessary to show attainment. These data show that the

area is in attainment and the monitoring data for 1995 show that no exceedances

were monitored in the entire ClevelandAkron-Lorain area. This shows that the provisions related to submitting a SIP revision to bring an area into attainment ofthe ozone NAAQS, such as the attainment demonstration, RFP, and contingency measures requirements are notnecessary since the area is already in attainment ofthe ozone NAAQS.

The weather in 1995 was more conducive toward forming ozone in many parts ofthe Country. Even though this was the case no exceedances were monitored at any ofthe monitors in the CAL area showing that the area has reduced its emissions to a level that has brought the CAL area into attainment of the ozone NAAQS.

(5) Comment:The Southwestern Pennsylvania Growth Alliance (Growth Alliance) is concerned that the redesignation ofthe Cleveland -AkronLorain area could adversely affect both the economy and air quality in southwestern Pennsylvania, and it feels that action on the applications from theseregions should be suspended until

a more comprehensive national solution to interstate transport ofozone and

ozone precursors is developed and implemented. The Growth Alliance believes that Southwestern Pennsylvania is being unfairly disadvantaged compared to neighboring states by the requirements created by the Clean Air Act, by USEPA, and by the Northeast Ozone Transport Commission.

(5) Response:USEPA's proposed action to determine that the ClevelandAkron-Lorain area has reached attainment and that it is not necessary for itto have an attainment demonstration, 15% rate ofreduction plan, and a contingency plan is different from redesignating the ClevelandAkron-Lorain area as an attainment area for ozone. In order forUSEPA to make

a determination concerning the 15% plan and other requirements, it is only necessary to show that the area has attained the ozone standard through

monitoring data. In order to be redesignated from nonattainment to attainment the area must meet the five redesignation requirements ofsection 107 ofthe CAA. One ofthe five redesignation requirements is that the

area have met all ofthe SIP requirements applicable to the area. A determination ofattainment renders

some ofthose requirements as inapplicable, based on the area attaining the standard, but the area would still have to meet the remaining applicable SIPrequirements before it could satisfy part ofthe requirements for redesignation. The ozone redesignation request for Cleveland-Akron-Lorain is being addressed in a separate part of this same Federal Register action. A discussion ofthe comments and responses received on the redesignation is given in that part ofthis action. In order for the CAL area to be redesignated from nonattainment to attainment it would have to meet all of the applicable redesignation requirements. If an area meets the criteria for redesignation nothing in the CAA suggests that redesignations should be delayed. Any issue regarding transport ofozone and its precursors
can and is expected to be dealtwith through the Ozone Transport and Assessment Group (OTAG) and USEPA's authority under section 110 (a)(2)(A) and (a)(2)(D) ofthe Act. See also Response to comment 2.
Determination Conclusion

The USEPA has determined that the Cleveland -Akron-Lorain (which includes the Counties ofAshtabula, Cuyahoga, Geauga, Lake, Lorain, Medina, Portage and Summit) has attained the ozone standard and continues to attain the standard at this time.

As a consequence ofthis determination that the ClevelandAkron-Lorain ozone nonattainment area has attained the ozone standard, the 

### requirements ofsection 182(b)(1) concerning the submission ofthe 15 percent plan and ozone attainment demonstration and the requirements of section 172(c)(9) concerning contingency measures are not applicable to the Cleveland -Akron-Lorain area. Additionally since this determination is occurring simultaneously with the

ozone redesignation to attainment, the determination will not be revoked in the event ofa violation. Rather, in the event ofa violation, the contingency measures in the approved maintenance plan would be triggered by a violation. 

### Ozone Redesignation Request

I. Background

On November 14, 1994, the OEPA submitted to the USEPA arequest for redesignation to attainment for ozone for the CAL area ofLorain, Cuyahoga, Lake, Ashtabula, Geauga, Medina, Summit and Portage. Additional information on the State public hearing and response to comments was submitted to USEPA on February 22, 1995. The redesignation requests were supported by technical information demonstrating that the requirements of section 107(d)(3)(E) ofthe Clean Air Act Amendments (CAAA) were met. On June 15, 1995, anotice was published in the Federal Register (60 FR 31433) which proposed approval ofthe redesignation requests to attainment for

ozone and the maintenance plans for the Ohio CAL moderate ozone nonattainment area counties.

I. Summary ofProposedRulemaking

The proposed rulemaking detailed how the State submittal fulfilled the redesignation requirements ofthe CAAA. Specifically, section 107(d)(3)(E) provides for redesignation if: (i) The Administrator determines that the area has attained the National Ambient Air 

### Quality Standards (NAAQS); (ii)The Administrator has fully approved the applicable implementation plan forthe

area under section 110(k); (iii) The Administrator determines that the improvement in air quality is due to permanent and enforceable reductions in emissions resulting from implementation ofthe applicable implementation plan and applicable Federal airpollutant control regulations and otherpermanent and enforceable reductions; (iv)The Administrator has fully approved a maintenance plan for the area asmeeting therequirements of section 175(A); and (v) the State containing such area has met all requirements applicable to the area under section 110 and Part D.

Included in the State submittal was a maintenance plan. A component ofthe maintenance plan is the maintenance demonstration which shows thatthe level ofemissions projected out 10 years will notexceed the attainment year inventory. The proposed rulemaking presented summary tables ofVolatile Organic Compounds (VOC) emissions, and NOx emissions projections for the CAL area counties. The OEPA has revised thebase year and projected year inventories numbers in response to comments made by Region 5. The VOC and NOx point source emissions projections for the year 2000 were estimated by USEPAbased on an average growth rate for the 1996to 2006 period. These estimates show thatthe totalemissions in the area are expected to remain below the attainment level of emissions. In addition, the NOxpoint
source emission projections do not account for emission reductions due to the Title IV Acid Rain requirements of the CAA, which would furtherreduce NOx emissions inthe area. The changes did not affect the State's ability to demonstrate maintenance. Therevised tables are presented below.

Additionally, the VOC and NOx emissions projected for the year 2006 in the above tables are considered emission budgets for purposes of transportation conformity.

The proposal stated that final approval ofthe CAL moderate nonattainment area counties was contingent upon final approval ofVOC reasonably available control technology (RACT)rules, the 1990 Base-year inventory, the section 182(f) NOx waiver request, the 182(b)(1) reasonable further progress plan (15% plan), the 182(b)(4) inspection and maintenance plan, the attainment demonstration, and the 172(c)(9) contingency measures. All oftheserequirements have either been met through full approval of state submittals or havebeen determined in this rulemaking to be no longer applicable. The final approval ofmost of the VOC RACT rules were published on March 23, 1995 (60 FR 15235), and became effective on May 22, 1995. Final approval ofRACT rules for major stationary sources not specifically covered by a USEPA Control Technique Guideline for RACT became effective on October 31, 1995, in aletter notice action from Regional Administrator Adamkus to the individual companies. A formal announcement ofthis was 

### made in the Federal Register. The Baseyear inventories were approved on December 7, 1995 (60 FR 62737) and effective on January 8, 1996. The NOx waiver request was approved on July 13, 1995 (60 FR 36051) and became effective on August 14, 1995. The I/M plan was approved on April 4, 1995 (60 FR 16989) and became effective on June 3, 1995.

A May 10, 1995, memorandum from John S. Seitz, Director, Office ofAir Quality Planning and Standards, entitled "Reasonable Further Progress, Attainment Demonstration, and Related Requirements for Ozone Nonattainment Areas Meeting the Ozone National Ambient Air Quality Standard", states that upon a determination made by USEPA that an area has attained the NAAQS for ozone, that area need not submit SIPrevisions concerning reasonable furtherprogress (15%) plan, 182(b)(1) attainment demonstrations, and 172(c)(9) contingency measures for as long as the area continues to meet the standard. Such a determination is made for the CAL area in a separate part of this rulemaking. Consequently, final approval ofthe redesignation request for the CAL counties ofLorain, Cuyahoga, Lake, Ashtabula, Geauga, Medina, Summit, and Portage is no longer dependent upon approval ofthe 15% plan, attainment demonstration, or section 172(c)(9) contingency measures. Public Comment/USEPA Response

In response to the request for written comments on the proposed rulemaking, USEPA received about 50 comment letters. Letters were received from concerned citizens, environmental groups, and industry. Over 30 ofthese letters were adverse comments on the propose rulemaking. The remaining comments were in support ofthe proposed rule. The following summarizes the adverse comments received and responds to them. The comments in support ofthe rule are not summarized below, but are available for public review in USEPA's docket. In an earlier part ofthis rulemaking comments and responses areprovided

on the determination ofattainment for the CAL area. To the extent that any comments under the determination section also apply to the ozone redesignation action for the CAL area they are also incorporated into the comments/responses under this section covering the ozone redesignation action for the CAL area. (1) Comment:Many ofthe commenters are opposed to the redesignation ofthe Cleveland-AkronLorain area to attainment on the grounds that they believe that more stringent emission control requirements and sanctions are needed to avoid unsafe pollution levels. These commenters believe that the benefits of health and environmental improvements to be achieved through stricter standards outweigh the increased costs ofemission controls on industry and on the public. Several commenters state that the ozone standard itselfshould be tightened, expressing concerns over longterm health impacts, impacts on children and the elderly, and impacts on smog levels still visible in the area.

(1) Response:The NAAQS were established to protect the public's health and welfare with an adequate margin of safety. Although additional reductions in VOCs mayprovide further health improvements, it is noted that the issue here is attainment ofthe ozone standard. The State ofOhio has met the requirements for the redesignation of the Cleveland-Akron -Lorain area to attainment ofthe ozone standard, including attainment ofthe ozone NAAQS. It is not clear that further reduction in ozone levels will provide significant health improvements.

With regard to arevised ozone standard, it should be noted that the USEPA alongwith States and science advisors, is the process ofreconsidering the ozone standard. Ifthe ozone standard is revised a number ofozone attainment and nonattainment areas maybe affected. A redesignation of Cleveland-Akron-Lorain to attainment at this time will not prevent this area from being redesignated to nonattainment ifit is subsequently found to be in violation ofa revised ozone standard. Until the NAAQS is revised, however, the 0.12 ppm NAAQS for ozone is the only appropriate standard against which to judge attainment. (2) Comment:People in the Cleveland-Akron-Lorain area suffer from sinus problems, and increased

occurrence ofasthma and other lifethreatening respiratory illnesses that are directly attributable to air pollution. The air is often oppressive and really unbreathable, especially in the kind of hot, humid weather that the area has experienced this summer. Infants and the elderly are affected by the higher tolerance ofozone levels now in force. We see people who become ill from polluted air whenever the ozone level rises. The current ozone standard is not health based. We wantto breathe cleaner air. We are opposed to the redesignation ofCleveland -AkronLorain because ofthe asthma epidemic and increasing number ofasthma deaths. The pervasiveness ofthe health threat posed far outweighs the inhibition ofindustrial expansion and limits on smokestack pollution.

### Federal Register / Vol. 61, No. 89 / Tuesday, May 7, 1996 / Rules and Regulations

(2) Response:The current ozone standard is a health based standard. It

was recently reviewed and reaffirmed,

see 58 FR 13008 (March 9, 1995). However, the ozone NAAQS is currently being reviewed to see ifthe standard should be changed and what the new standard would be, see 59 FR 5164 (February 3, 1994). A staffreport was recently released that discusses this review ofthe ozone NAAQS. But unless and until the ozone NAAQS is changed

- itremains the standard to use for comparison against ozone monitoring data in the area. Those data indicates attainment ofthe ozone standard.

(3) Comment:In Cleveland-AkronLorain the air smells. There are also foul odors coming from factories during the early morning hours that are waking us up and makingus nauseated.

(3) Response:At the Federal level the Clean Air Act (CAA) does not provide specificrequirements for companies to control odors. Odor is not an issue pertinent to the ozone standard or the attainment ofthat standard. We have, however, made our enforcement group
aware ofthese complaints to see what

can be done. Further, existing facilities must continue to operate existing air pollution control equipment in accordance with applicable rules, regulations and permits, and sources that are problematic in terms ofposing

anuisance to area residents maybe referred to the State and local environmental enforcement stafffor investigation.

(4) Comment:Several commenters expressed concern that trucks and buses pollute the air byblowing outblack smoke and that cleaning up emissions from cars is not sufficient.

(4)Response:The USEPA agrees that cleaning up emissions from cars is not enough. Trucks and buses also produce significant pollution. The USEPA has set stringent standards for new heavy duty diesel engines beginning with the 1988 model year, with additional improvements to be made with the 1991 and 1994 model year engines. The black smoke from diesel trucks and buses is particulate matter which is a visible air pollutant. Trucks and buses also contribute to ozone air pollution because they produce hydrocarbons and NOx. The NOxemission standard has been tightened from 10.7 grams per brake horsepower per hour (g/bhp-hr) in 1985 to 6.0 in 1988 and 5.0 in 1991. The hydrocarbon emission rate for diesel engines is set at 1.3 g/bhp-hr. Particulate emission standards have been tightened from 0.60 g/bhp-hr in 1988 to 0.10 g/ bhp-hr in 1994 for all new heavy duty engines. As the older trucks and buses

are replaced by the newer, cleaner engines the pollution from these vehicles will be significantly reduced.

In October 1993, the USEPA required the use ofa cleaner diesel fuel throughout the country. Diesel fuel used in on-highway compression ignition engines contains less sulphur than earlier fuels. Lower sulphur reduces the amount ofindirect particulate and improves the operation ofnew diesel engines using particulate trap oxidizers to control direct particulate emissions. It is estimated that the use oflow-sulphur diesel fuel reduces direct and indirect particulate by approximately 28 percent from the baseline fuel. Air quality impacts offuel controls are projected to reduce particulate by 2.3 to 8.3 micrograms per cubic meter and sulphur dioxide by 7 to 16 micrograms per cubic meter in a metropolitan area the size ofCleveland-Akron-Lorain.

The State ofOhio will implement its inspection and maintenance (JIM) program beginning in 1996. The authorizing State legislation for the IM program requires the testing ofdiesel powered vehicles up to 10,000 pounds for opacity (smoke). Buses are also required to meet emission standards for smoke, hydrocarbons and carbon monoxide.

The reductions in hydrocarbon, and NOx emissions from trucks and buses will contribute to maintaining the ozone standard and protecting the public's health. Particulate issues are separate from ozone issues and are not relevant for consideration here. While the standards for particulate emissions will greatly reduce the amount ofsmoke emitted from trucks and busses, it is not expected to have a significant effect on
ozone levels and as a result is not pertinent to an ozone redesignation request. (5) Comment:Several commenters have expressed confusion over the relationship between the proposed redesignation and the protection ofthe "ozone layer." One commenter in particular requests that the USEPA explain the "whole ozone picture." (5) Response:At the very outset of this response, itmust be noted that "ozone" referred to in the proposed redesignation is chemically identical to the "ozone" referred to in the term "ozone layer." In both situations ozone refers to a gas composed ofmolecules with three oxygen atoms each.

In the case ofthe "ozone layer", one is referring to the layer ofthe Earth's stratosphere where ozone is found in relatively high concentrations. Ozone in this layer is formed through the reaction ofoxygen molecules (two oxygen atoms each) and high energy electromagnetic radiation from the Sun. Oxygen atoms are freed when oxygen molecules are impacted by the high energy radiation. Some ofthese freed oxygen atoms combine with oxygen molecules to form

ozone molecules. Within this layer of the atmosphere, ozone is a significant absorber ofhigh energy ultraviolet radiation from the Sun. Ifthis ultraviolet radiation reached the surface ofthe earth in sufficient intensity, significant, undesirable biological damage could result to surface organisms. Concerns over potential damage to the protective ozone layer has led to efforts to reduce the emissions of gasses which are believed to directly or indirectly eliminate ozone molecules.

In the case ofthe proposed of Cleveland-Akron-Lorain, one is dealing with ozone found in the lowest levels of the atmosphere. At this level ofthe atmosphere, high ozone levels are not typically found (naturalprocesses can lead to peak ozone levels of0.04 to 0.06 parts per million, well below the ozone standard of0.12parts per million). Manmade (anthropogenic) emissions of volatile organic compounds, oxides of nitrogen, and other gases, in the presence of sunlight and relatively

warm temperatures, can lead to ozone formation ofconsiderably higher concentrations. This chemical formation process involves hundreds ofchemical reactions and differs significantly from the process that forms ozone in the stratosphere. There is no significant exchange ofozone between the lower atmosphere, where high ozone levels are undesirable, and the stratosphere, where high ozone levels are desirable for the protection oflife on earth.

Ozone concentrations in excess ofthe

ozone standard are shown, based on
numerous health studies and correlation ofhealth data and monitored ozone concentrations, to be damaging to human health, particularly causing problems with the human respiratory system. For thisreason, ozone has been listed as a primary pollutant with a defined health-based standard.

(6)Comment:The air quality in Cleveland-Akron-Lorain is lousy and there has been no improvement in the quality ofour air. If anything, Iwould say things are worse.

(6)Response:With respect to ozone levels in the CAL, the air quality has improved significantly since the late 1980's. During 1988 there were a number ofmonitored readings above .150 parts per million in the area. During the last four years the highest concentration monitored was .127 ppm. CAL achieved attainment ofthe ozone standard at the end of 1994, by monitoring attainment ofthe ozone NAAQS during the three previous years

HeinOnline -- 61 Fed. Reg. 20464 1996

### Federal Register / Vol. 61, No. 89 / Tuesday, May 7, 1996 / Rules and Regulations

(which are 1992, 1993, and 1994). The

area continued to attain the standard since that time.

Section 107(d)(3)(E)(iii) requires that, for the USEPA to approve a redesignation, it must determine that the improvement in air quality is due to permanent and enforceable reductions in emissions. The September Calcagni memorandum, at page 4, clarifies this requirement by stating that "[a]ttainment resulting from temporary reductions in emission rates (e.g., reduced production or shutdown due to temporary adverse economic conditions) or unusually favorable meteorology would not qualify as an air quality improvement due to permanent and enforceable emission reductions." As discussed in the June 15, 1995 Federal Register proposed rulemaking, the State ofOhio demonstrated that permanent and enforceable emission reductions are responsible for the recent improvement in air quality. This demonstration was accomplished through an estimate ofthe reductions (from 1990 to 1993) ofVOC achieved through Federal measures such as the Federal Motor Vehicle Emissions Control Program (FMVECP) and fuel volatility rules implemented from 1990- 1993, as suggested by the September Calcagni memorandum.

Volatile Organic Compound (VOC) emissions are one ofthe precursors that help to form ozone. The total emission reductions achieved from 1990 to 1993

were 65 tons ofVOCper day. This is a 14 percent reduction in VOCs, which corresponds to the drop in ozone concentrations in the area. These emission reductions were primarily the result ofthe FMVECP, Automobile Inspection and Maintenance program, and Gasoline Reid Vapor Pressure (RVP) reductions from 10.5 pounds per square inch (psi) in 1989, to 9.0psi in 1992. The VOC emissions are expected to continue to decrease in the future due to the Federal Motor Vehicle Emissions Control Program, Stage II vapor recovery program, and the Enhanced Automobile Inspection and Maintenance Program. The NOxemissions are also expected to decrease in the future due to the Federal Motor Vehicle Emissions Control Program and the Enhanced Automobile Inspection and Maintenance Program.

(7) Comment:I am sure you are being bombarded with requests to change the designation to attainment, on the grounds that the region willbe hurt economically if this is not done. To me, such arguments ignore two fundamental points. First, there is not evidence that stricter environmental regulations hurt the economy. A clean environment does not mean lessjobs, it can mean more jobs. In fact, there is evidence that indicates the opposite. Second, even if this is true, we would be selling our health, and the health ofour world and

our children, for economic benefit. This does not seem a good trade. There is entirely too much emphasis on business economic considerations over health considerations. The cost to industry may be high, but what about the cost to pay for increased health problems? Air pollution results in hundreds of thousands ofdollars worth ofasthma illnesses and deaths each week. This should be spent on pollution controls instead.

It would be reprehensible ifthe agency charged with the protection of health and the environment capitulated to vested, self-serving interests that place the almighty dollar ahead of human health and welfare. The redesignation request should not be approved.

(7) Response:The approval ofthe

ozone redesignation request for Cleveland -Akron-Lorain is based on the

area meeting the five requirements of section 107 ofthe CAA. Itis notbased

on economic grounds. The first ofthe five requirements of section 107 is that the area has attained the National Ambient Air Quality Standard for
ozone, which it has. The NAAQS for

ozone is set at a level designed to protect the public's health and monitoring data show that the area is meeting the standard. (8) Comment:One commenter, although not expressing opposition to the proposed redesignation, does express opposition to the approach used in the Cleveland-Akron-Lorain area of trying to get the public to reduce emissions only during critical high

ozone potential periods. The commenter favors a permanent curtailment of emissions so that people with related health risks, such as asthma, will not have to seek the shelter ofairconditioned places during such periods. (8)Response:It is agreed that, where possible, permanent emission controls should be implemented to minimize

ozone levels and to attain the ozone standard. It should be recognized that many permanent emission controls, such as reasonably available control technology, transportation control
measures, and vehicle inspection/ maintenance, have been implemented in the Cleveland-Akron-Lorain area. The maintenance plan takes into account that these emission controls will be maintained despite the redesignation of the area as an area in attainment ofthe

ozone standard. The permanent and enforceable emissions reductions are discussed under comment number six, and in comment 4 in the determination ofattainment section.

(9) Comment:A number of commenters believed the air monitoring in the area was inadequate. Several

concerns were noted: Commenters stated that there is presently insufficient monitoring both in terms ofwhat is monitored and the number of monitoring stations (specifically, a lack ofozone monitoring in Geauga County

was cited by several commenters).

(9)Response:The requirements for ambient air quality monitoring are detailed in 40 CFR part 58. The federal requirements include: The use of approved air monitoring equipment; quality assurance ofmonitoring data; appropriate network design; operating schedule; and siting ofindividual monitors. In determining attainment or nonattainment status of an area for the NAAQS for ozone, only air monitors sampling for ozone are relevant. Monitoring forprecursors ofozone (such as VOCs and NOx) can be beneficial in understanding ozone formation. For determining the air quality concentrations ofozone in an
area and determining attainment ofthe

ozone standard, ambient ozone monitors

are considered.

The Cleveland-Akron -Lorain ozone monitoring network consists often ambient ozone monitors: three in Cuyahoga County, two in Lake County, and one each in Ashtabula, Lorain, Medina, Portage and Summit Counties. The monitoring network is reviewed by the USEPA. The individual monitoring sites meet the federal monitoring requirements. The commenters are correct in notingthat Geauga County is downwind ofthe urban area and in a location that would be expected to receive high ozone concentrations. However, the USEPA believes that decisions on the air quality can be made with the current network because the monitors cover an adequate geographic

area to be representative ofthe nonattainment area. Ozone monitors are located in every county that is contiguous to Geauga County. All of these monitors are in attainment ofthe

ozone NAAQS, including Lake County which is also downwind ofthe main urban area and would be expected to have similar air quality to Geauga County. Based on this USEPA believes that Geauga County is also in attainment ofthe ozone NAAQS.

(10) Comment:One commenter believed that the original readings that brought about the "bad rating" were taken in an industrial area surrounded by freeways inundated with Cleveland Browns fans. The commenter believed 

## 20465

HeinOnline -- 61 Fed. Reg. 20465 1996

### Federal Register / Vol. 61, No. 89 / Tuesday, May 7, 1996 / Rules and Regulations

the monitoring readings to be unrepresentative.

(10)Response:The highest ozone readings are not typically found in industrial areas or near freeways. Industries and traffic produce hydrocarbons (also called volatile organic compounds) and NOx pollution that react in the presence ofsunlight to form ozone. Thisreaction takes place

over aperiod of several hours and thus the highest ozone concentrations are typically found 20 to 40 miles in the downwind direction. The USEPA considers all valid, quality assured monitoring data in the area in assessing the air quality. The moderate ozone nonattainment designation was based

on 3 years ofozone monitoring data (1987-1989) and was based on the fourth highest reading (.157 the design value) at the monitoring site in Akron, Ohio. Other ozone monitoring sites in the area also had ozone concentrations in the range ofamoderate classification. For example, the site at Jefferson Elementary School in Eastlake, Ohio had a design value of .152 for the 1987- 1989 time period. The ozone monitoring data now shows an improvement in air quality that demonstrates attainment of the health based ozone standard. All air monitoring data is available to the public from the national USEPA Aerometric Information and Retrieval System (AIRS) databank.

(11) Comment:The fact that this region did not adopt reformulated, less ozone-producing gasoline with fewer VOC's for summertime use clearly demonstrates the lack ofcommitment to clean air.

(11) Response:While the ClevelandAkron-Lorain area was notrequired to adopted reformulated gasoline in order to be redesignated, they did choose an Enhanced Automobile Inspection and Maintenance program (I/M) as a maintenance measure to be implemented in the area. This program
was chosen as the most cost effective program that the area could use for maintaining the standard while still providing room for growth in the area.

(12) Corn ment:Several commenters expressed dissatisfaction with the inspection and maintenance program for automobiles. Some were concerned about gaps in the I/M program that reduced the effectiveness. One commenter suggested other pollution reduction measures. A commenter believed that the vehicle inspection and maintenance program was not effective. The commenter believed that the I/M funds would be better spent on enforcing the speed limit, gettingrid of high polluting vehicles, doing more on "Ozone Action Days" or making these mandatory, and giving incentives for sharingrides. One commenter was against the more stringent IM program.

(12) Response:The IM program for automobiles is a very cost-effective program for reducing pollution. Studies show that a small percentage of vehicles

are producing alarge portion ofthe pollution in ametropolitan area. Automobiles that are not wellmaintained or that have pollution control equipment that has been disabled emit air pollution that can increase ozone concentrations. The I/M program will identify these automobiles and require repairs. Compared to other forms ofpollution control, the IM program is a low-cost alternative. The enhanced IM program is estimated to cost between $500 to $900 dollars per ton ofVOC pollution reduced. This compares to a cost ofapproximately $5,000 per ton for abasic program, $5,000 to $10,000 dollars per ton of VOC reduced for additional stationary

source controls beyond the current RACT required in the Cleveland-AkronLorain area. The USEPA agrees that an effective IM program is important. The enhanced IM program adopted by Ohio and which began in January 1996, is the best and most cost effective testing program recommended bythe USEPA.

An additional feature ofthe State's enhanced IM program, designed to improve repair-effectiveness, is the requirement that automobile technicians become certified to repair vehicles which fail the test. The auto technician training program requires technicians to undergo a training program to ensure they are able to perform repairs on current new-technology vehicles and vehicles ofthe future. Technicians and repair facilities will be graded on the effectiveness ofrepairs and this information will be available to the public in order to make informed decisions on where to take their vehicle for repairs. This technician training and certification program began implementation in October 1995, and is being supervised bythe OEPA. (13) Comment:A commenter expresses the concern that control of emissions from aircraft as they travel

over the area (and over the United States in general) have notbeen given enough consideration. The commenter believes aircraft emissions must be considered alongwith emissions from industries and automobiles in the control ofair pollution. (13) Response:It should be noted that States, under the requirements of section 182(a)(1) ofthe Clean Air Act, have included aircraft emissions in a base year emissions inventory for each

ozone nonattainment area. These aircraft emissions were projected to the 10-year maintenance period in Ohio's maintenance plan for the ClevelandAkron-Lorain area, and were shown, along with emissions from other
sources, to not cause aprojected violation ofthe ozone standard.

(14) Comment:A number of commenters were concerned that the redesignation would affect transportation choices and transportation planning and would contribute to more pollution. Concerns

were expressed about: The need for

more bike paths, the need forimproved public transit, the need to discourage driving. Specific concern was expressed about express lanes on 1-271 which would impact the environment. Another commenter had concerns about a subway being dropped from the transportation planning, a lack of bicycle facilities, more interchanges and freeways and new lane additions. There

was concern about a tollway from Toledo to Portsmouth instead oflight rail that would be upwind ofthe populated current nonattainment areas and would add pollution to the areas. The commenter wanted pollution prevention through better transportation choices.

(14)Response:The redesignation to attainment does not negate the need for the area to make smart transportation choices. The transportation conformity requirements still apply to the area as a maintenance area. The area will need to demonstrate that emissions are not exceeding the mobile source emission budget in the maintenance plan. The Northeast Ohio Area wide Coordinating Agency (NOACA) is the local metropolitan planning organization for the Cleveland-Akron -Lorain area and performs the conformity analysis on the transportation plan. Conformity to the emission budget is designed to prevent the area from increasing mobile source emissions to the point where the air quality standards are exceeded. Conformity will also provide assurance that a project will not be done ifit would cause or contribute to a violation ofthe ozone NAAQS in the CAL area.

The commenters are correct in noting that transportation measures such as improvements inbicycle paths and facilities and improved public transit will contribute to better air quality by reducing the number ofautomobiles and the number ofvehicle miles oftravel. The commenters are also correct in their

concerns about increasing freeway capacity and tollways, as these types of projects will encourage additional vehicular traffic. The USEPA believes that the conformity requirements will allow the area to make local decisions 

## 20466

HeinOnline -- 61 Fed. Reg. 20466 1996

### Federal Register / Vol. 61, No. 89 / Tuesday, May 7, 1996 / Rules and Regulations

on transportation planning while assuringthat mobile source emissions will not increase. Increases to the mobile source budget are only allowed if there is an excess in the total projected emissions for the area.

Projects such as tollways that are built in the maintenance area would also be subject to conformity. Tollways that are in attainment areas are not currently required to meet any conformity tests. It is possible that projects ofthis type could affect air quality downwind; however, the USEPA believes that the cleaner vehicle standards will contribute to preventing degradation of the air. See also the response to comment 18.

(15) Corn m ent: Over Lake Erie there is

a gray and yellow mass ofpollution. There is also a trail ofsmoke that rises from the smoke stacks ofthe East Lake Electric Power plant, and the trucks and buses are also emitting smoke. When I

am at ahigh point on ahill looking down atdowntown Cleveland, Ican barely see the buildings. It's as if they

are behind a cloud ofdirt, smoke, and other pollution. We need to change this.

(15)Response:USEPA has avariety of programs addressing the commenter's

concerns. The "trail of smoke" from the East Lakepower plant is particulate matter, which is regulated both by limits

on the mass ofparticulate matter and by limits on the opacity ofthe plume. Smoke from trucks and buses is being limited bynew emissions standards that have been made achievable by new limitations on the sulfur content of diesel fuel. USEPA is updating its visibility regulations to reduce the impairment ofvisibility due to air pollution. Nevertheless, USEPA evaluates attainment ofthe air quality standards based on quantitative measurements ofair pollutant concentration. Since these measurements indicate that the ozone standard is being attained, USEPA must conclude that this criterion for redesignation is satisfied.

(16) Comment:Several commenters

are opposed to the redesignation because they believe it will lead to less USEPA oversight ofexisting emission control regulations and, therefore, to increased air pollution.

(16)Response:All volatile organic compound emission control regulations in place at the time ofthe redesignation ofthe Cleveland -Akron-Lorain area will remain in place unless it is ultimately shown through photochemical dispersion modeling that such control

measures are not necessary for continued attainment ofthe ozone standard. These regulations will continue to be enforced by the State and will remain federally enforceable. (17)Corment:One commenter asserted that section 107(d)(e)(E)(v) requires that a state meet all applicable requirements under section 110 and Part D. While claiming that Cleveland satisfies all 172(c) requirements, USEPA acknowledges that some components have not yet completed regulatory review. 60 FR 31437. (17)Response:All applicable components, including those were referred to in the proposal as pending regulatory review, have now completed regulatory review. The Clean Air Act requires that the Cleveland -AkronLorain area meet all applicable requirements before the area is redesignated. USEPA approved the 1990 base year emissions inventory in a final rulemaking published on December 7, 1995 (60 FR 62737). The remaining VOC RACT rules for the area were approved in letter notice rulemakings dated October 31, 1995 and announced in the Federal Register. In a separate part of this final rulemaking USEPA determined that the 15% plan and contingency measures requirements are
no longer applicable to the ClevelandAkron-Lorain area. USEPA's rational for this action is contained in the rulemakings dated August 25, 1995 (60 FR44277), June 29, 1995 (60 FR 33742, and 60 FR 33781), and this final rulemaking. As a result ofthese actions the Cleveland-Akron-Lorain area has met all ofthe fully approved SIP requirements. These requirements were met before USEPA published this final rulemaking taking action on the redesignation requests.

In response to the comment on the protection ofthe public health. The public's health is protected as evidenced by the monitoring data collected in the area. The data show that the air quality levels are meeting the NAAQS for ozone. These standards

were set to protect the public health and welfare. (18) Comment:By this proposed approval, USEPA claims the redesignation request relieves Ohio from submitting SIP revisions providing transportation and general conformity criteria guidance. (18)Response:USEPA in this notice does not relieve Ohio from conformity requirements. Rather, USEPA has determined that those requirements will continue to apply after the area is redesignated, and therefore need not be fulfilled as a condition ofredesignation. Section 176(c) ofthe Act requires States to revise their SIPs to establish criteria and procedures to ensure that Federal actions, before they are taken, conform to the air quality planning goals in the applicable SIP. The requirement to determine conformity applies to transportation plans, programs and projects developed, funded or approved under Title 23 U.S.C. orthe Federal Transit Act ("transportation conformity"), as well as to all other Federal actions ("general conformity"). Section 176 further provides that the conformity revisions to be submitted by the States must be consistent with Federal conformity regulations that the Actrequired the USEPA to promulgate. Congress provided for the State revisions to be submitted one year after the date ofpromulgation offinal USEPA conformity regulations.

The USEPA promulgated final transportation conformity regulations on November 24, 1993 (58 FR 62188), and general conformity regulations on November 30, 1993 (58 FR 63214). These conformity rules require that States adopt both transportation and general conformity provisions in the SIP for areas designated nonattainment or subject to a maintenance plan approved under section 175A ofthe Act. Pursuant to 40 CFR 51.396 ofthe transportation conformity rule and 40 CFR 51.851 of the general conformity rule, the State of Ohio is required to submit a SIP revision containing transportation conformity criteria and procedures consistent with those established in the Federal rule byNovember 25, 1994, and November 30, 1994, respectively. Ohio submitted transportation and general conformity SIP revisions on August 17, 1995. The USEPA has not yet approved the transportation conformity rules as part ofthe SIP. Final rulemaking on the general conformity rules is expected

soon.

The USEPA believes it is reasonable to interpret the conformity requirements

as notbeing applicable requirements for purposes ofevaluating the redesignation request under section 107(d). The rationale for this is based on a combination oftwo factors. First, the requirement to submit SIP revisions to comply with the conformity provisions ofthe Act continue to apply to areas after redesignation to attainment, since such areas would be subject to a section 175A maintenance plan. Therefore, the State remains obligated to adopt the transportation and general conformity rules even afterredesignation and would risk sanctions for failure to do so. While redesignation ofan area to attainment enables the area to avoid further compliance with most requirements of section 110 and part D, since those requirements are linked to the nonattainment status ofan area, the conformity requirements apply to both

### Federal Register / Vol. 61, No. 89 / Tuesday, May 7, 1996 / Rules and Regulations

nonattainment and maintenance areas. Second, USEPA's federal conformity rules require theperformance of conformity analyses in the absence of state-adopted rules. Therefore, a delay in adopting Staterules does notrelieve

an area from the obligation to implement conformity requirements.

Because areas are subject to the conformity requirements regardless of whether they are redesignated to attainment and must implement conformity under Federal rules ifState rules are not yet adopted, the USEPA believes it isreasonable to view these requirements as not being applicable requirements for purposes ofevaluating

aredesignation request.

For thereasonsjust discussed, the USEPA believes that the ozone redesignation request for the CAL area may be approved notwithstanding the lack offully approved State transportation and general conformity rules. Thispolicy was also exercised in the Tampa, Florida ozoneredesignation finalized on December 7, 1995 (60FR 62748).

(19) Comments:A commenter argued that the submission is defective under section 107(d)(3) because ofthe absence ofa complete and fully approved implementation plan. The commenter asserted that USEPA cannot excuse Ohio's failure to submitrequired SIP revisions coming due afterthe November 15, 1994 filingofthe redesignation request. The commenter complained thatUSEPA in itsproposal
was illegally attempting torectify gaps by waiving applicability ofnecessary SIPrequirements, including the requirements of 15percent RFP, attainment demonstration, and contingency measures. Under section 107(d)(3)(E)(ii), anonattainment area may be redesignated only after USEPA has fully approved the applicable implementation plan forthe area under section 110(k).

Under the APA, theAdministrator may not suspend applicability ofSIP requirements except byredesignation pursuant to 107(d)(e)(E). This canbe done only ifUSEPA has fully approved the SIPunder 110(k). See 107(d)(3)(E)(iii). Congress allotted USEPA no discretion in determining what constitutes the applicable plan, but directed itto look at section l10(k), which does not give theAdministrator authority to decide what constitutes the "applicable requirements ofthis Act." Under section 107(d),the Administrator
can only grant a request to redesignate to attainment ifthe state has met all applicable requirements under section 110 and Part D,and after the state has adopted a complete implementation plan. (19)Response:USEPA has not suspended orgranted the CAL an exemption from any applicable requirements. Rather, USEPA has interpreted the requirements of section 182(b)(1)(A)(i) and 172 (c)(9) as not being applicable once an area has attained the standard, as long as it continues to do

so. This is not a waiver ofrequirements that bytheir terms clearly apply; itis a determination that certain requirements

are written so as to be operative only if the area is not attaining the standard.

The May 10 Policy was clear about the consequences ofthe policy for redesignations. First, it made plain that

a determination ofattainment is not tantamount to a redesignation ofan area to attainment. Attainment is only one of the criteria set forth in 107(d)(3)(E). To be redesignated, the State must satisfy all ofthe criteria of 107(d)(3)(E), including the requirement ofa demonstration that the improvement in the area's air quality is due to permanent and enforceable reductions, and the requirements that the area have

a fully-approved SIP which meets all of the applicable section 110 and part D requirements, and a fully approved maintenance plan.

Upon a determination of attainment, however, the 182(b)(1)(A)(i) requirements ofRFP and attainment plans, and the 172(c)(9) requirement of contingency plans are no longer considered applicable requirements under section 107(d)(3)(E). They would

no longer be included amongthose

measures whose approval is part ofthe requirement ofhaving afully approved SIP.

A commenter contended that, by relying upon its determination of attainment, USEPA is avoiding the redesignation requirements of 107(d). This is not the case. What USEPA has done is make a determination that since the area is attaining the standard, which is a factual determination, certain provisions ofthe CAA, whose express purpose is to achieve attainment ofthe standard, do not require SIP revisions to be made by the State for so long as the

area continues to attain the standard. This has longbeen USEPA's policy with respect to the section 172(c)(9) contingency measures and section 172(c)(2) RFP requirement. See general preamble at 57 FR 13498. USEPA has also made determinations regarding section 182(f) NOx waivers at or before the redesignation ofan area and therefore not required NOx RACT submissions to approve such redesignations. Seethe Bay Area redesignation at 59 FR49361. USEPA disagrees with the commentor's analysis ofthe language and structure ofthe CAA. USEPA's statutory analysis was explained in detail in the June 8, 1995 direct final rule and in the May 10, 1995 memorandum from John Seitz. USEPA further elaborated upon this analysis, and responded to many ofthe concerns raised bythe plaintiffs, in its final determination ofattainment ofOzone Standard for Salt Lake and Davis Counties, Utah, and Determination Regarding Applicability ofCertain Reasonable Further Progress and Attainment Demonstration Requirements. See 60 FR 36,723 (July 18, 1995). To the extent here pertinent, such portions ofthat notice, including the responses to comments, are incorporated herein byreference.

Thus, USEPA disagrees with the commentors' view that USEPA is not complying with allthe redesignation requirements of 107(d)(3)(E). The area has a fully approved plan for and has met all applicable requirements. USEPA has interpreted SIP submission requirements of section 182(b)(1) regarding reasonable further progress and attainment demonstration plans, and ofsection 172(c)(9) regarding contingency measures to be implemented in the event an area fails to make reasonable further progress or attain the standard by the attainment date, not to apply for so long as the area continues to attain the standard. Since they are not applicable, fulfillment of theserequirements is not necessary to meet the redesignation criteria of 107(d)(3)(E).

The commenter challenges USEPA's authority to determine certain SIP requirements inapplicable, and then bootstraps that argument to complain that since CAL has notmet these requirements, the redesignation request onlypartially fulfills 107(d)(E)(v). The commenter argues that this is because the state has not met all "applicable" requirements under section 110 and Part D;but the requirements it points to are the very ones that USEPA has determined are inapplicable.

USEPA rejects this kind ofcircular argument. Since USEPA has determined that the statute does not require certain submissions so long as the area is in attainment, those inapplicable requirements cannot serve as the basis for concludingthat the redesignation request is defective. Under the criteria ofsection 107(d)(E)(3) itself, a state need onlymeet all applicablerequirements, and have afully approved plan that contains all requiredelements. Thus USEPA's interpretation is fully consistent with the criteria of section 

## 20468

HeinOnline -- 61 Fed. Reg. 20468 1996

### Federal Register / Vol. 61, No. 89 / Tuesday, May 7, 1996 / Rules and Regulations

107(d)(3). Since USEPA has determined that the 15%, attainment demonstration, and contingency plan requirements are not applicable to CAL, and has found the SIP to be fully approvable without them, the CAL area has fairly met the criteria of section 107(d)(3). Certainly USEPA, after determining that these requirements are inapplicable, could not in good faith conclude that the redesignation request is defective because it fails to meet them.

Thus USEPA concludes that, where it has made a determination ofattainment that results in the suspension of requirements, it may rely on that determination and its consequences in considering the approvability ofa redesignation request.

For the reasons stated above and elsewhere in this Notice, in the June 29, 1995 Federal Register notices (60 FR 3372, 33781), in the May 10, 1995 memorandum, and in the 60 FR 36,723 (July 18, 1995) Utah notice, USEPA does not believe that the rulemaking violates any section ofthe CAA, nor does it circumvent the redesignation requirements under section 107(d)(3)(E).

(20) Comment:Citizens Commissions for Clean Air in the Lake Michigan Area stated that USEPA's action is not a reasonable interpretation ofUSEPA's nondiscretionary mandate "to protect and enhance the quality ofthe Nation's air resources so as to promote the public health and welfare and the productive capacity ofits population[.]}. section 101(b)(1).

(20)Response:The USEPA disagrees with the commentor's statement that its action violates section 101(b)(1). Section 101(b)(1) does not establish a nondiscretionary duty; it is a statement ofpurpose-a purpose that USEPA is not disregarding in this action. the area has attained the primary ozone standard, a standard designed to protect public health with an adequate margin of safety. (see section 109(b)(1)). USEPA's action does not relax any of the requirements that have led to the attainment ofthe standard. Rather, its action has the effect of suspending requirements, for additional pollution reductions, above and beyond those that have resulted in the attainment ofthe health-based standard.

(21) Comm ent:A commentor asserts that USEPA's action violates the Administrative Procedure Act and the CAA through its reliance on unpublished memoranda ofJohn Calcagni and John Seitz and the General Preamble for the Implementation of Title I ofthe Clean Air Act Amendments of 1990, 57 FR 13498 (April 16, 1992). According to the commentor, reliance

on those documents is inappropriate and illegal since those documents were issued without opportunity for notice and comment and are not enforceable regulations. (21) Response:USEPA's reference to and reliance on those documents, all of which are either published or publicly available and a part ofthe record ofthis rulemaking, is in no way illegal under provisions ofeither the CAA or the Administrative Procedures Act. (The commentor cited no specific provisions ofeither act). USEPA agrees that such documents do not establish enforceable regulations; they do not purport to be anything but guidance. That is precisely why USEPA has performed this rulemaking-a notice-and-comment rulemaking to take comment on its statutory interpretations and factual determinations in order to make a binding and enforceable determination regarding the CAL area. The June 29, 1995 Federal Register notice referred to USEPA's prior policy memoranda not as binding the Agency to adopt the interpretations being proposed therein, but rather as a useful description ofthe rationale underlying those proposed interpretations. USEPA has explained the legal and factual basis for its rulemaking in the June 29, 1995 Federal Register notice and afforded the public

afull opportunity to comment on USEPA's proposed interpretation and determination fully consistent with the applicable procedural requirements of the Administrative Procedures Act. (The procedural requirements of section 307(d) ofthe CAA do not apply to this rulemaking since it is not among the rulemakings listed in section 307(d)(1).) (22) Comment:USEPA claims that, in accordance with the October 1994 Nichols memorandum, "that areas being redesignated need not comply with the requirement that a NSR program be approved prior to redesignation so [long] as they have an approved Prevention ofSignificant Deterioration (PSD) SIP or delegated PSD authority." 60 FR at 31439. USEPA apparently believes it can replace NSR with PSD, but the CAA does not grant the Administrator such discretion. (22) Response:The USEPA believes that the CAL area may be redesignated to attainment notwithstanding the lack ofa fully-approved NSRprogram meeting the requirements ofthe 1990 Act amendments and the absence of such an NSR program from the contingency plan. This view, while a departure from pastpolicy, has been set forth bythe USEPA as its new policy in

amemorandum from Mary Nichols, Assistant Administrator for Air and Radiation, dated October 14, 1994, entitled Part DNew SourceReview (part DNSR) Requirements forAreas RequestingRedesignationto Attainment.

The USEPA believes that its decision notto insist on a fully-approved NSR program as aprerequisite to redesignation isjustifiable as an exercise ofthe Agency's general authority to establish de minimis exceptions to statutory requirements. SeeAlabamaPowerCo. v. Costle, 636 F.2d 323, 360-61 (D.C. Cir. 1979). Under AlabamaPowerCo. v. Costle,the USEPAhas the authority to establish de minimis exceptions to statutory requirements where the application of the statutory requirements would be of trivial or no value environmentally.

In this context, the issue presented is whether the USEPA has the authority to establish an exception to the requirements of section 107(d)(3)(E) that the USEPA have fully-approved a SIP meeting all ofthe requirements applicable to the area under section 110 and part Doftitle Iofthe Act. Plainly, the NSR provisions of section 110 and part D arerequirements that were applicable to the Ohio area seeking redesignation at the time ofthe submission ofthe request for redesignation. Thus, on its face, section 107(d)(3)(E) would seem to require that the State have submitted and the USEPAhave fully-approved apart D NSR program meeting the requirements ofthe Actbefore the areas could be redesignated to attainment.

Under the USEPA's de minimis authority, however, it may establish an exception to an otherwise plain statutory requirement ifits fulfillment would be oflittle or no environmental value. In this context, it is necessary to determine what would be achieved by insisting that there be a fully-approved part DNSR program in place prior to the redesignation ofthe CAL area. Forthe followingreasons, the USEPA believes that requiring the adoption and fullapproval ofa part D NSRprogram prior to redesignation would notbe of significant environmental value in this

case.

Ohio has demonstrated that maintenance ofthe ozone National Ambient Air Quality Standards (NAAQS) will occur even ifthe emission reductions expected to result from the part D NSR program do not

occur.The emission projections made by Ohio to demonstrate maintenance of the NAAQS considered growth in point

source emissions (alongwith growth for other source categories) and were premised on the assumption that the Prevention ofSignificant Deterioration (PSD)program, rather than the part D NSR, would be in effect, during the 

### 20469

HeinOnline -- 61 Fed. Reg. 20469 1996

### Federal Register / Vol. 61, No. 89 / Tuesday, May 7, 1996 / Rules and Regulations

maintenance period. Under NSR, significant point source emissions growth would not occur. Michigan assumed that NSR would not apply after redesignation to attainment, and therefore, assumed source growth factors based on projected growth in the economy and in the area's population. (It should be noted that the growth factors assumed maybe overestimates under PSD, which would restrain source growth through the application ofbest available control techniques.) Thus, contrary to the assertion ofthe commentor, Ohio has demonstrated that there is no need to retain the part D NSR

as an operative program in the SIP during the maintenance period in order to provide for continued maintenance of the NAAQS. (Ifthis demonstration had not been made, NSR would have had to have been retained in the SIP as an operative program since it would have been needed to maintain the ozone standard.)

The otherpurpose that requiring the full-approval ofapart D NSR program might serve would be to ensure that NSR would become a contingency provision in the maintenance plan required for these areas by section 107(d)(3)(E)(iv) and 175A(d). These provisions require that, for an area to be redesignated to attainment, it must receive full approval ofa maintenance plan containing "such contingency provisions as the Administrator deems necessary to assure that the State will promptly correct any violation ofthe standard which occurs after the redesignation ofthe area as an attainment area. Such provisions shall include a requirement that the State will implement all measures with respect to the control ofthe air pollutant concerned which were contained in the SIP for the area before redesignation of the area as an attainment area." Based

on this language, itis apparent that whether an approved NSRprogram must be included as a contingency provision depends on whether it is a "measure" for the control ofthe pertinent air pollutants.

As the USEPA noted in the proposal regarding this redesignation request, the term "measure" is not defined in section 175A(d) and Congress utilized that term differently in different provisions ofthe Act with respect to the PSD and NSR permitting programs. For example, in section 110(a)(2)(A), Congress required that SIPs include "enforceable emission limitations and other control measures, means, or techniques

. . . as may be necessary or appropriate to meet the applicable requirements ofthe Act." In section 110(a)(2)(C), Congress required that SIPs include "a program to provide for the enforcement ofthe measuresdescribed in subparagraph (A), andregulation of the modification and construction of any stationary source within the areas covered by the plan as necessary to

assure that NAAQS are achieved, including a permit program as required in parts C and D." (Emphasis added.) If the term measures as used in section 110 (a)(2)(A) and (c) had been intended to include PSD and NSR there would have been no point to requiring that SIPs include both measures and preconstruction review under parts C and D (PSDor NSR). Unless "measures" referred to something other than preconstruction review under parts C and D, the reference to preconstruction review programs in section 110(a)(2)(C) would be rendered mere surplusage. Thus, in section 110(a)(2) (A) and (C), it is apparent that Congress distinguished "measures" from preconstruction review. On the other hand, in other provisions ofthe Act, such as section 161, Congress appeared to include PSD within the scope ofthe term "measures."

The USEPA believes that the fact that Congress used the undefined term "measure" differently in different sections ofthe Act is germane. This indicates that the term is susceptible to

more than one interpretation and that the USEPA has the discretion to interpret itin areasonable manner in the context of section 175A. Inasmuch

as Congress itselfhas used the term in

amanner that excluded PSD and NSR from its scope, the USEPA believes it is reasonable to interpret "measure," as used in section 175A(d), not to include NSR. That this is areasonable interpretation is further supported by the fact that PSD, aprogram that is the corollary ofpart D NSR for attainment
areas, goes into effect in lieu ofpart D NSR.3 This distinguishes NSR from other required programs under the Act, such as inspection and maintenance and

3The USEPA is not suggesting that NSR and PSD

are equivalent, butmerely that they are the same type ofprogram. The PSD program is a requirement in attainment areas and designed to allow new

source permitting, yet contains adequate provisions
to protect the NAAQS. If any information including preconstruction monitoring, indicates that an area is not continuing to meet the NAAQS after redesignation to attainment, 40 CFR part 51 appendix S (Interpretive Offset Rule) or a 40 CFR 51.165(b) program would apply. The USEPA believes that in any area that is designated or redesignated as attainment under section 107, but experiences violations of theNAAQS, these provisions should be interpreted as requiring major

new or modified sources to obtain VOC emission offsets ofat least a 1:1 ratio, and as presuming that 1:1 NOx offsets are necessary. See October 14, 1994 memorandum from Mary Nichols entitled Part D New Source Review (part DNSR)Requirements for AreasRequestingRedesignationtoA ttainment. Reasonably Available Control Technology (RACT) programs, which have no corollary for attainment areas. Moreover, the USEPAbelieves that those other required programs are clearly within the scope ofthe term "measure." 4

The USEPA's logic in treating part D NSR in this mannerdoes not mean that other applicable part D requirements, including those that have been previously met and previously relied upon in demonstrating attainment, could be eliminated without an analysis demonstrating that maintenance would be protected. As noted above, Ohio has demonstrated that maintenance would be protected with PSD in effect, rather than part D NSR. Thus, the USEPA is notpermitting part D NSRto be removed without a demonstration that maintenance ofthe standard will be achieved. Moreover, the USEPAhas not amended its policy with respect to the conversion ofother SIP elements to contingency provisions, which is that they may be converted to contingency provisions only upon a showing that maintenance will be achieved without them being in effect. Finally, as noted above, the USEPA believes that the NSR requirement differs from other requirements, and does not believe that the rationale for the NSR exception extends to other required programs.

As the USEPAhas recently changed its policy, the position taken in this action is consistent with the USEPA's current national policy. That policy permits redesignation to proceed without otherwise required NSR programs having been fully approved and converted to contingency provisions provided that the area demonstrates, as has been done in this
case, that maintenance will be achieved with the application ofPSDrather than part DNSR. (23) Comment:A violation does not

occur until the third "exceedance", this is deceptive and doesn't help people get information that the air is polluted. Even though .124 ppm is above the "standard" of0.12ppm; because of rounding that terrible air wouldn't even be counted as an exceedances or violation.

4The USEPA also notes that in the case ofthe Cleveland, Ohio area, allpermits to install formajor volatile organic compound (VOC) emission sources and major VOC emission source modifications issued by the State in the moderate ozone nonattainment areas since November 15, 1992have complied with the 1.15 to 1.0 VOC emissions offset ratio. In addition, permits to install cannot be issued under the Prevention ofSignificant Deterioration (PSD)program unless the applicant

can demonstrate that theincreased emissions from thenew or modified source will not result in a violation ofthe NAAQS.

### Federal Register / Vol. 61, No. 89 / Tuesday, May 7, 1996 / Rules and Regulations

Cleveland -Akron-Lorain's ozone monitors are not on all year. We should be monitoring year-round. We get unusual weather in northeast Ohio. We've had temperatures in the 80's during every month when we are not required by law to monitor. Ifwe had

aviolation during these months (we have had extreme haze then and lots of emergency room visits from respiratory patients), we have no way ofknowing,

so these days don't count, either. Iam against the redesignation ofClevelandAkron-Lorain for these reasons.

(23)Response:Published guidance (Guideline fortheInterpretationof OzoneAir QualityStandards, January 1979, EPA-450/4-79-003), which is part ofthe ozone standard by reference in 40 CFR part 50, appendix H, notes that the stated level ofthe standard is determined by defining the number of significant figures to be used in comparison with the standard. For example, a standard level of0.12ppm
means that measurements are to be rounded to two decimal places (0.005 rounds up), and therefore, 0.125 ppm is the smallest three-decimal concentration value in excess ofthe level ofthe standard that is considered

an exceedance.

Since ozone levels decrease significantly in the colder parts ofthe year in many areas, ozone is required to be monitored at monitors only during the "ozone season" which is listed in Appendix D to 40 CFR part 58 forOhio

as April through October. This seasonal definition was initially set in 1986 based on temperature data. Months where the monthly mean daily maximum temperature is less than 55 degrees Fahrenheit were generally excluded from the season. In ClevelandAkron-Lorain, this occurs from November through March. In different

areas ofthe country where months are cooler than 55 degrees Fahrenheit,

ozone concentrations greater than .08 ppm are unlikely to occur. In addition actual ozone monitoring data for the Cleveland -Akron-Lorain area collected from 1987 though 1994 for the months ofApril and October show only three recorded concentrations above .100 parts per million. The highest monitored concentration was .109 parts per million during October 1992. The

ozone NAAQS of .12 ppm was not exceeded in the Cleveland-Akron-Lorain

area for the months ofApril and October from 1987 though 1994. Given the generally lower temperatures ofthe other winter months compared to April and October, it is expected that these months would nothave monitored an exceedance ofthe ozone NAAQS. (24)Comment:A commenter was concerned that because ofthe redesignation to attainment the area would become exempt from congestion mitigation and air quality (CMAQ) funds which local transit agencies relied

on for new buses and expanded service thus increasing air pollution. (24) Response:The federal CMAQ program is designed to give additional money for air quality nonattainment

areas to use on transportation projects that will improve the air quality and bring the area into attainment ofthe air quality standards. The United States Department ofTransportation (USDOT) revised their CMAQ guidance on July 13, 1995, to allow redesignated areas to have a 2 year transition period to insure continuity in CMAQ funding for projects which are programmed in the first 2 years ofthe transportation improvement program at the time the

area is redesignated to attainment. Although Cleveland -Akron-Lorain will lose the additional CMAQ funds after the 2-year transitional period, the projects already programmed for funding will now be able to continue implementation. Airpollution is not expected to increase because the stricter standards for new cleaner cars, trucks and buses will help to decrease pollutant emissions. The USEPA believes the air pollution emissions will thus continue to decrease or atleast maintain the levels that have brought the area into attainment. (25)Comment:The 15% plan approved for Greater Cleveland -AkronLorain fell short ofthe required reduction because the area did not choose to do reformulated gasoline. The

area has not met this requirement and should not be redesignated.

(25)Response:USEPA determined that, based on USEPA's determination ofattainment, the requirement for a 15% reduction in volatile organic emissions in the area is no longer applicable. See the final action also contained in this final rulemaking. Since this is no longer an applicable requirement, the area is not required to meet itbefore the CAL area can be redesignated. The 15% reduction plan that was submitted for the CAL area did not rely on reformulated gasoline to achieve the emissions reduction.

(26)Comment:Several commenters believed there was a potential conflict of interest when the same entity (i.e. the City ofCleveland) does the monitoring and also applies for redesignation.

(26)Response:The ambient air data collected by State and local agencies are required to meet very specific quality

assurance measures that are detailed in 40 CFR 58.10 and appendix A. The 

### USEPAQuality Assurance manual gives
more detailed guidance on operation of ambient air monitors. The USEPA audits the State and local agencies on a regular basis to ascertain thatthe appropriate quality assurance measures arebeing implemented. In the case of the Cleveland local agency, the State air agency (OhioEnvironmental Protection Agency) isresponsible for conducting accuracy audits on the airmonitoring equipment being operated bythe Cleveland local agency. In addition, the USEPAconducts audits ofthe air monitoringnetwork. Precision and Accuracy audits are reported on a regular basis to the USEPA and recorded in the national AIRS data bank. This information is available tothe public. Thisoversight ensures thequality ofthe datarelied upon forredesignation.
III.RulemakingAction

On June 29, 1995, USEPAproposed to determine thatthe 15% plan, attainment demonstration, and contingency
measures plan forthe Cleveland-AkronLorain area areno longer applicable requirements, since the area has attained the ozone NAAQS. The USEPA received several comments pertaining to theproposed rulemaking. These comments were considered and responses aredetailed in the above section oftherulemaking on the determination ofattainment. USEPA believes thatthe determination of attainment is still warranted and is takingfinal action to determine thatthe requirements for a 15% emissions reduction plan, attainment demonstration, and contingency

measures plan arenot applicable at this time.

On June 15, 1995, USEPAproposed to approve the OEPA request for redesignation to attainment and the maintenance plan for ozone for theCAL moderate nonattainment area counties ofLorain, Cuyahoga, Lake, Ashtabula, Geauga, Medina, Summit, and Portage. The USEPA received about 50 comment letters pertaining to theproposed rulemaking. The comments were considered and responses aredetailed in the above section oftherulemaking

on the ozone redesignation request. The USEPAbelieves that theredesignation requirements ofSection 107(d) are satisfied and is taking final action to approve therequests forredesignation to attainment and the maintenance plan for the CAL counties ofLorain, Cuyahoga, Lake, Ashtabula, Geauga, Medina, Summit, and Portage.

USEPA finds that there isgood cause for thisredesignation, SIP revision, and

### Federal Register / Vol. 61, No. 89 / Tuesday, May 7, 1996 / Rules and Regulations

determination ofattainment tobecome effective immediately upon publication because a delayed effective date is unnecessary due tothe nature ofa redesignation to attainment, determination ofattainment, which exempts the areas from certain Clean Air Act requirements that would other wise apply toit. The immediate effective date for thisredesignation is authorized under both 5 U.S.C. 553(d)(1), which provides that rulemaking actions maybecome effective less than 30 days after publication iftherule "grants or recognizes an exemption orrelieves a restriction" and section 553(d)(3), which allows an effective date less than 30 days after publication "as otherwise provided by the agency for good cause found and published with therule."

Nothing in this action should be construed as permitting, allowing or establishing a precedent for any future request forrevision to any SIP. USEPA shall consider each request forrevision to the SIP in lightofspecific technical, economic, and environmental factors and in relation to relevant statutory and regulatory requirements.

This action has been classified as a Table 3action for signature by the Regional Administrator under the procedures published in the Federal Register on January 19, 1989 (54FR 2214-2225), asrevised by aJuly 10, 1995, memorandum from MaryNichols, Assistant Administrator forAir and Radiation. The Office ofManagement and Budget (OMB) has exempted this regulatory action fromExecutive Order 12866 review.

Under the Regulatory Flexibility Act, 5 U.S.C. 600 etseq., USEPA must prepare a regulatory flexibility analysis assessing theimpact ofany proposed or final rule on small entities (5 U.S.C. 603 and 604).Alternatively, USEPA may certify that therule will not have a significant impact on a substantial number ofsmall entities. Small entities include small businesses, small not-forprofit enterprises, and government entities withjurisdiction over populations ofless than 50,000.

Redesignation ofan area to attainment under section 107(d)(3)(E) ofthe CAA does not impose any new requirements

on smallentities. Redesignation is an action that affects the status ofa geographical area and does not impose anyregulatory requirements on sources. The Administrator certifies that the approval oftheredesignation request will not affect a substantial number of smallentities.

SIP approvals under section 110 and subchapter I,Part Dofthe CAA do not create any new requirements, but simply approve requirements that the State is already imposing. Therefore, because the federal SIP-approval does not impose any new requirements, I certify that it does not have a significant impact on any small entities affected. Moreover, due to the nature ofthe federal-state relationship under the CAA, preparation ofaregulatory flexibility analysis would constitute federal inquiry into the economic reasonableness of state action. The CAA forbids USEPA to base its actions concerning SIPs on such grounds. Union ElectricCo. v. U.S. E.P.A., 427 U.S. 246, 256-66 (S.Ct. 1976); 42U.S.C. 7410(a)(2).

Under sections 202, 203, and 205 of the Unfunded Mandates Reform Act of 1995 (Unfunded Mandates Act), signed into law on March 22, 1995, USEPA must undertake various actions in association with proposed or final rules that include a Federal mandate that may result in estimated costs of$100 million

or more to the private sector, or to State, local, or tribal governments in the aggregate.

Through submission ofthe state implementation plan or plan revisions approved in this action, the State and any affected local or tribal governments have elected to adopt the program provided for under section 175A ofthe Clean Air Act. The rules and commitments being proposed for approval in this action may bind State, local and tribal governments to perform certain actions and also may ultimately lead to the private sector being required to perform certain duties. To the extent that the rules and commitments being proposed for approval by this action will impose or lead to the imposition of any mandate upon the State, local or tribal governments either as the owner
or operator of a source or as aregulator,

or would impose or lead to the imposition of any mandate upon the private sector, USEPA's action will impose no new requirements; such

sources are already subject to these requirements under State law. Accordingly, no additional costs to State, local, or tribal governments, or to the private sector, result from this action. The USEPA has also determined that this action does not include a mandate that may result in estimated costs of$100 million or more to State, local, or tribal governments in the aggregate or to the private sector.

Under section 307(b)(1) ofthe Clean Air Act, petitions forjudicial review of this action must be filed in the United States Court ofAppeals for the appropriate circuit by July 8, 1996. Filing apetition for reconsideration by the Administrator ofthis final rule does not affect the finality ofthis rule for the purposes ofjudicial review nor does it extend the time within which a petition forjudicialreview may be filed, and shall not postpone the effectiveness of such rule or action. This action may not be challenged later in proceedings to enforce its requirements. (See section 307(b)(2).)

a. StatutoryAuthority

This regulation is issued under sections 302, 304 and 328 ofthe Emergency Planning and Community Right-to-Know Act (EPCRA).
b. Background

On October 17, 1986, the President signed into law the Superfund Amendments and Reauthorization Act of 1986 (SARA), Pub. L. 99-499 (1986). Title III ofSARA, the Emergency Planning and Community Right-toKnow Act of 1986 (EPCRA), established

aprogram designed to encourage state and local planning and preparedness for spills or releases ofextremely hazardous substances and to provide the public and local governments with information concerning chemical releases and the potential chemical risks in their communities. Subtitle A ofthe Act establishes the framework forlocal emergency planning. Under section 302, a facility which has present an extremely hazardous substance (EHS) in excess of its threshold planning quantity (TPQ) must notify its state emergency response commission (SERC) and participate, as necessary, with the local emergency planning committee (LEPC) in the local emergency planning process. Section 302 directed EPA to publish the list of extremely hazardous substances as an interim final rule within 30 days ofthe enactment of EPCRA. Section 302(a)(2) required that the listbe identical to the list compiled by EPA in 1985 as part ofEPA's Chemical Emergency Preparedness Program. Under section 302(a)(4), EPA is authorized to revise the list, but in undertaking any such revision, EPA must take into account the "toxicity, reactivity, volatility, dispersibility, combustibility, orflammability of a substance." The term "toxicity" is defined to include "any short- or longterm health effects which may result from a short-term exposure to the substance."

EPA published the list of402 extremely hazardous substances on November 17, 1986 (51 FR41570). On the same day, EPA proposed the deletion of40 substances from the EHS list on the basis that their original listing

was in error. On April 22, 1987, 52 FR 13388, EPA announced that it was deferring the proposed delisting ofthese substances, pending an evaluation ofthe long-term effects from short-term exposure to each ofthem. This deferral

was in response to comments from members ofthe public who argued that the proposed rule was premature. On November 23, 1987, the District Court for the District ofColumbia inA.L. Laboratories,Inc. v. Environmental ProtectionAgency issued an order requiring EPA to remove several substances from the EHS list, reasoning that Congress did not intend to include in the statutorily designated list substances listed due to "clerical error." 

### 20474

HeinOnline -- 61 Fed. Reg. 20474 1996

### Federal Register / Vol. 61, No. 89 / Tuesday, May 7, 1996 / Rules and Regulations

It is on the basis ofthis rulingthat EPA proposed on October 12, 1994 (59 FR 51816), the removal offour chemicals.

Section 304 ofEPCRA establishes requirements for immediate reporting of certain releases ofEHSs and hazardous substances (HSs) listed under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) to SERCs and LEPCs, similar to the release reporting provisions ofCERCLA section 103. Although similar, CERCLA section 103 and EPCRA section 304 differ somewhat in purpose. CERCLA provides generally for federal planning and coordination of entities and for federal contingency plans. CERCLA section 103 requires federal notification for any release ofa hazardous substance in an amount equal to or in excess ofits RQ. EPCRA is designed to protect the public in the event ofdangerous chemical releases through the establishment oflocal and state emergency response capability. EPCRA section 304 requires, in addition to any federal notification, notification to state and local authorities for any release ofan EHS in an amount equal to or in excess ofits RQ. The potential hazards posed byEHSs make state and local notification critical to effective and timely emergency response. EHSs are acutely toxic chemicals which cause both severe sort- and long-term health effects after a single, briefexposure. In many cases, local and state authorities may be the first and onlyresponders to the release ofan EHS.

Notifications are required if a release ofan EHS or HS is equal to or above the reportable quantity (RQ). Section 304(a) ofEPCRA provides that chemicals on the EHS list which do not have an RQ assigned to them byregulation, will have a reportable quantity of 1 pound. Currently, 204 EHSs have the statutory one-pound RQ. On August 30, 1989 (54 FR 35988), EPA proposed to modify the statutory RQs for 232 EHSs using a proposed modification ofthe CERCLA RQ methodology.

c. Today'sRulemaking

EPA is today taking final action on the two proposed rules published in the Federal Register on August 30, 1989 and October 12, 1994. As discussed below, EPA is not yet taking final action

on some aspects ofthe proposed rules. EPA is adjusting the reportable quantities of204 extremely hazardous substances.' Thisrule will make the

1Although a total of 215 EHSs have one-pound statutory RQs, this ruleis adjusting the RQs of 204 of these EHSs. The remaining 11 EHSs with onepound statutory RQs were designated CERCLA hazardous substances in a February 9, 1995 final rule (60 FR 7824); the Agency is currently reportable quantities for these chemicals the same as their threshold planning quantities. EPA is also finalizing the proposal to remove phosphorus pentoxide, diethylcarbamazine citrate, fenitrothion and tellurium from the EHS list.

On August 30, 1989, EPA proposed the adjustment ofthe TPQ for isophorone diisocyanate. Today's rule reflects the current TPQ for isophorone diisocyanate. However, an adjusted TPQ and RQ will be published in a future notice.
II. RQ AdjustmentMethodologies

a. TPQ Methodology

EPA's methodology for establishing threshold planning quantities for EHSs under EPCRA consists ofinitially determining the minimum short term exposure concentration in air that would lead to serious irreversible health effects in the general population when exposed to the substance for relatively short duration. This is the so-called "level ofconcern." (See the Threshold Planning Quantities Technical Support Document, April 7, 1987.)

There are two ways to determine a "level ofconcern." Ifitis available for

a chemical, EPA may use one-tenth of the Immediately Dangerous to Life and Health (IDLH) level established by the National Institute for Occupational Safety and Health (NIOSH). The IDLH is the maximum concentration of a substance in air to which a healthy worker can be exposed for 30 minutes and escape without suffering irreversible health effects or impairing symptoms. Ifthe IDLH value is not available, as is the case for most ofthe EHSs, EPA determines an IDLH equivalent value using available toxicity data with an adjustment factor.

The level ofconcern is then divided by a factor "V" which represents the extent to which the material can volatilize and become airborne and dispersed. This approach is explained in the November 17, 1986 Federal Register notice (51 FR41580). Dividing the level ofconcern by "V" provides the index value for an EHS.

The final threshold planning quantity is then determined by arelative ranking ofthe index values for all ofthe chemicals on the EHS list. The index values and their corresponding threshold planning quantities are found in the Threshold Planning Quantity Technical Support Document. This approach is generally based on the

developing a rulemaking to adjust the CERCLA and EPCRA one-pound RQs for these 11 substances. The substances are identified in 40 CFR Part 355 by the footnote "d." quantity ofthe chemical which when released will generate the level of

concern at a distance of 100 meters.
b. CERCLA RQMethodology

The CERCLA RQ methodology uses a two step process to determine the possibility ofharm from the release of

ahazardous substance. The methodology begins with an evaluation ofsix intrinsic physical, chemical, and toxicological properties associated with each hazardous substance. These properties are known as the "primary criteria." Each substance is evaluated according to the applicable "primary criteria," and an RQ value is determined for each applicable criterion. The "primary criteria" RQ for each hazardous substance is the lowest value ofall the applicable criteria. For example, if the Agency evaluates hazardous substance A under the RQ adjustment methodology, identifies both aquatic toxicity and mammalian toxicity data on the substance, and sets a tentative RQ of 100pounds on the basis ofaquatic toxicity and 1000 pounds on the basis ofmammalian toxicity, the 100 pound value will be the applicable "primary criteria" RQ. Upon completion ofthe evaluation ofthe "primary criteria" RQ, secondary adjustment criteria based on the natural degradation processes ofBHP (biodegradation, hydrolysis, and photolysis) are assessed. Ifa hazardous substance, when released into the environment, degrades (within 5 days) to a less hazardous form by one
or more ofthe BHP processes, its primary criteria RQ is raised one level; ifthe substance degrades to a more hazardous form, its RQ may be lowered.

c. ProposedMethodology

For approximately 60 ofthe 232 chemicals proposed for adjustment on August 30, 1989, the CERCLA methodology adjusted RQs that were too high for purposes ofemergency notification under EPCRA. The reportable quantities under the CERCLA methodology in these cases are higher than the substances' EPCRA threshold planning quantity. To rectify this discrepancy, the August 30, 1989, notice proposed to modify the CERCLA RQ methodology by integrating the TPQ into the CERCLA RQ methodology. As proposed, after the two-step CERCLA RQ process had been applied to the chemicals, an additional step of comparing the tentative RQ to the substances' TPQs was applied. Ifthe TPQ was lower than the tentative RQ, the RQ would be adjusted to the TPQ level or lower.

HeinOnline -- 61 Fed. Reg. 20475 1996

### Federal Register / Vol. 61, No. 89 / Tuesday, May 7, 1996 / Rules and Regulations

d.Alternative Chosen

In the proposed rule ofAugust 30, 1989, the Agency was seeking comment

on the various alternatives that could be used to set the reportable quantities. At the time the RQ adjustments were proposed, the Agency anticipated that the EHSs would be designated CERCLA hazardous substances as proposed on January 23, 1989 (54 FR 3388). The Agency, however is not finalizing at this time the proposal to designate these chemicals as CERCLA hazardous substances. Today's rule does not affect any CERCLA hazardous substances. Therefore, the Agency is notutilizing or modifying the CERCLA RQ methodology at this time. Instead, the Agency has decided to adjust the 1 pound EHS RQs to the same level as their respective TPQs. 2

The Agency believes that it is appropriate to rely on the TPQ methodology rather than the CERCLA methodology to adjustEHS RQs for several reasons.

First, reporting ofEHS releases is required because EHSs are acutely toxic and will potentially pose an immediate hazard upon release. Thus, EHS RQs should be adjusted based on substances' potential for immediateeffects. The TPQ methodology, designed specifically for the EHSs, is based on such effects, utilizing a "level ofconcern" based upon short-term exposure concentrations that could lead to serious irreversible health effects.

Second, use ofthe CERCLA secondary criteria ofBHP is inappropriate for adjustingEHS RQs. The BHP analysis is used to increase a substance's RQ by taking into account its natural chemical degradation. EHSs can cause severe health effects after only a single, brief exposure which may occur prior to any chemical degradation. The BHP analysis and higher RQs based on chemical degradation are not suitable in this context.

Third, as with RQs, the Agency adjusts TPQs based on the possibility of harm from the release ofa specific substance. In the Threshold Planning Quantity Technical Support Document to the proposed rule ofNovember 17, 1986 (51 FR41570) to adjust TPQs, EPA stated that the TPQ should represent a quantity that could cause serious health consequences if an accident were to

occur with that quantity. Consistent with this statement, EPA modelled a variety ofrelease scenarios to generate the relative ranking ofeach EHS and to

2The release ofEHSs which are already CERCLA hazardous substances is reportable at theRQ levels applicable under CERCLA. (EPCRA section 304 (a)(1)). determine the six TPQ quantities (1, 10, 100, 500, 1,000, and 10,000 pounds). Since the TPQ methodology is based on the possibility ofharm from release, the Agency believes that it is appropriate to rely on it to adjust RQs as well.

Finally, like CERCLA RQs, EPCRA RQs do not reflect a determination that

arelease ofa substance will always be hazardous atthe RQ level and never hazardous below that level. EPA has not attempted to make such a determination because the actual hazard will vary with the unique circumstances ofthe release. For this reason, EPA encourages SERCs and LEPCs to consider the RQ during their emergency planning process involving facilities with extremely hazardous substances. 

### III. Response to Comments on August 

### 30, 1989 Proposal

Many ofthe comments received in response to the Federal Register notice ofAugust 30, 1989, are not addressed today because they concerned the designation ofEHSs as CERCLA hazardous substances and the adjustment ofRQs for those substances under CERCLA. As stated above, the Agency is not taking action on modifying the CERCLA RQ methodology or listingEHSs as CERCLA hazardous substances atthis time. For a complete list ofcomments and the Agency's responses, see the responses to comments document in the Docket of this Federal Register notice.

a. ThresholdPlanningQuantity Methodology

The Agency received several comments on its proposed use ofthe TPQ methodology to adjust RQs. These commenters believed that the use ofthe TPQ methodology was inappropriate because the RQ and the TPQ address different regulatory requirements.

EPA believes that the TPQ methodology is appropriate for these chemicals. Although the RQs and TPQs trigger two distinct notification requirements, both quantities are adjusted based on the possibility of harm from the release ofa specific substance. Thus, even though TPQ (EPCRA §302) notification is not triggered by an actual release, the TPQ is based upon the potential harm from

an actual release. In addition, the particular concern with EHSs is that they will potentially pose an immediate hazard upon release. Notification requirements should be based on the potential for these immediate effects, and the TPQ methodology (developed specifically for the EHS list) is in fact based upon the potential for immediate effects. Forthese reasons, the Agency believes that the use ofthe TPQ methodology is appropriate to set RQs for extremely hazardous substances. However, because these chemicals are notbeing added to the CERCLA hazardous substance list, modification ofthe CERCLA RQ methodology is not warranted at this time.
b.SulfurDioxide

The adjusted RQ for sulfur dioxide

was proposed at 100-pounds. Several commenters from the petroleum industry commented that the 100-pound RQ is too low and would require needless and excessive reporting for the petroleum sector. In the petroleum sector, sulfur dioxide is a combustion product created when hydrogen sulfide from crude oil and natural gas is flared. The commenters referenced the Federal Clean Air ActNew Source Performance Standards that they state allow coal fired power plants to emit 200,000 pounds per day ofsulfur dioxide.

The proposed RQ for sulfur dioxide

was set at 100-pounds based on the proposed modified CERCLA RQ methodology. In the final rule ofApril 22, 1987 (52 FR 13378), the TPQ for sulfur dioxide was adjusted to 500- pounds. Because there is no 500-pound CERCLA RQ level, the sulfur dioxide RQ was proposed at 100-pounds. As stated earlier in thisrule, EPA is not modifyingthe CERCLA RQ methodology at this time, but is adjusting RQs to the TPQ level. The final EPCRA RQ for sulfur dioxide is 500-pounds.

EPA does not agree that the existence ofa 200,000 pounds per day standard for one sector means that the EPCRA RQ should be set at ahigher RQ level. Sulfur dioxide is used in many industries other than the petroleum sector, for example, sulfuric acid production, water purification and the pulp and paper industry. While flares and stacks are designed to lift the sulfur dioxide into the atmosphere, ground level releases of sulfur dioxide, including releases from containers storing sulfur dioxide maybe more hazardous to the community. Since EPA sets one RQ to incorporate all probable release scenarios, EPA believes that the 500 pound RQ based on the substance's IDLH value provides an appropriate level.

EPA notes that the release reporting requirements ofEPCRA section 304 work in conjunction with the federally permitted release exemption under CERCLA section 101(10) and the continuous release reporting requirements under CERCLA section 103. Releases that are federally permitted and those that are continuous 

## 20476

HeinOnline -- 61 Fed. Reg. 20476 1996

### Federal Register / Vol. 61, No. 89 / Tuesday, May 7, 1996 / Rules and Regulations

have reduced reporting requirements under EPCRA section 304.

c. Hydrogen Chloride

Several commenters correctly pointed out that the phrase "gas only" was omitted from the hydrogen chloride listing in the tables proposing to revise Appendices A and B to 40 CFR part 355. In today's rule, this omission is corrected.

In the final rule published in the Federal Register December 27, 1989 (54 FR 53057), EPA raised the reportable quantity for Hydrogen chloride (gas only) to 5,000pounds. This is the same
as the reportable quantity for hydrogen chloride (a synonym ofhydrochloric acid) under CERCLA section 103.
d. SulfurTrioxide

Several commenters believed that a reportable quantity for sulfur trioxide above 100 pounds is warranted. EPA, however, disagrees. The 100pound TPQ for sulfur Trioxide is based upon acute toxicity. EPA agrees that some releases of sulfur trioxide above 100-pounds may not be hazardous based upon the conditions ofthe release (e.g. from a flare or stack). However, 100-pound releases of sulfur trioxide at ground level (e.g. releases during sulfuric acid and explosive manufacturing) may pose
ahazard to the community. An RQ incorporates allprobable release scenarios so that persons off-site can determine the level ofresponse necessary. Therefore, the Agency believes that the 100-pound RQ for sulfur trioxide based upon its acute toxicity is appropriate.
IV. Listing Corrections

EPA is making final arule that was originally proposed on October 30, 1994, to remove phosphorus pentoxide, diethylcarbamizine citrate, finitrothion and tellurium from the extremely hazardous substances list.3

Substances are listed as EHSs based

on toxicity criteria. Substances are screened using acute animal toxicity data for the most sensitive mammalian species and are placed on the list ifthey meet one ofthe following criteria:

* LC5 04 !<0.5mg/L * DermalLD505

### <50mg/kg * Oral LD5o<25mg/kg

3 On October 30, 1994, EPA proposed the adjustment ofthe TPQ forisophorone diisocyanate. The final rule on this adjustment will be published in a future notice.

4"LC 5 0 " refers to that concentration ofa substance in the air that is expected to cause the death of50 percent ofa defined experimental population.

5 "LD50"refers to that dose ofa substance expected to cause the death of50 percent ofa defined experimental population. IfLC50 or LD5 0 data are not available, 

### then LCLO orLDLO data areused. Substances thatmeet one ofthese criteria have the potential for causing harm ifaccidently released and are, therefore, designated asEHSs.

EPA listed phosphorus pentoxide based on information presented in an abstract. This source reported an LC50 of 

### 0.061 mg/L for guinea pigs and an LC50 

### of0.271 mg/L formice exposed for 1 hour to smoke generated from burning red phosphorus. A significant limitation ofthis study is thatthe toxic effects cannot be directly related to phosphorus pentoxide. Therefore, these data are insufficient for listing phosphorus pentoxide as an EHS. In addition, the Elemental Phosphorus Ad Hoc Solid Waste Group submitted a study that indicated thatthe LC50 

### forrats exposed to phosphorus pentoxide for4 hours is greater than 0.99 mg/L,well above the .5 mg/L listing criteria. Based on the insufficient information in theoriginal study and the information ofthe more recent study,EPA has decided to
remove phosphorus pentoxide from the EHS list.

EPA listed diethylcarbamazine citrate based on information presented in a Russian data compilation thatlisted an LC50

### forrats equal to 0.309 mg/L for a 4-hour exposure. Review ofthis information indicated that thetoxicity values presented were unverifiable because the study details were not available. In addition, SmithKline Beecham submitted a study that reported no deaths ofrats from exposure to either 1.63 mg/L or 2.38 mg/L for 1 hour. Based on thepoor quality ofthe original study and the additional information received, EPAhas decided to remove diethylcarbamazine citrate from the EHS list.

EPA listed fenitrothion based on a study thatreported an LC50

### equal to 0.378 mg/L for a4-hour exposure. EPA's review ofthis study concluded that a toxic impurity had resulted in an erroneously low value for the LC50. In 

### addition, a surfactant was present that altered the permeability ofthe skin and cell membranes ofthe test animals, making them more susceptible to fenitrothion's toxic effect. Information submitted by Sumitomo Chemical America, Inc., reported an LC50 

### greater than 2.210 mg/L. Based on theAgency's review and the additional information, fenitrothion is being deleted from the EHS list.

EPA listed tellurium metal based on
a study thatreported an oral LD50

### of20 mg/kg. Review ofthis study indicted that sodium tellurate, which is listed as an EHS, was used in the study rather than tellurium metal. The Selenium Tellurium Development Association also submitted a study that reported an LD50 greater than 5000 mg/kg for tellurium metal. Based on this information, EPA is deletingtellurium from the list ofEHSs.


### V. Response to Comments on October 12, 1994,Proposal

EPA received one comment from the Clean Water Fund ofNorth Carolina objecting to the removal ofphosphorus pentoxide from the EHS list. The Clean Water Fund questions the validity ofan unpublished 1987 toxicity study showing no toxic effects in exposed animals, at levels up to .99 mg/L of phosphorus pentoxide aerosol. That study however, did not determine the level ofthe chemical in question in the chamber atmosphere. The analytical method determined onlytotal phosphorus, which was then converted
to an equivalent concentration of phosphorus pentoxide in air. The Clean Water Fund argues, therefore, that the pentoxide should remain on the list because the 1980 and 1982 combustion experiments established that the pentoxide was a major component ofthe smoke and "because the analytical techniques employed by the 1980 study mayhave actually synthesized the pentoxide from other (possiblyless dangerous) phosphorus compounds actually present in the test chamber." The Agency assumes Clean Water Fund believes that because the pentoxide could have been synthesized from less toxic compounds, the pentoxide presented the toxic character ofthe test chamber gas.

EPA disagrees. The 1980 and 1982 studies show that, in burning the phosphorus, there is apotential for the production of several oxides of phosphorus. Regardless ofhow pentoxide was formed (as noted bythe Clean Water Fund) or whether the various oxide compounds are more or less toxic, the fact still remains that the studies did not distinguish which ofthe various oxides caused the high toxicity ofthe smoke. While the 1987 study showed no toxicity ofphosphorus pentoxide, it also is not conclusive because it did not indicate a direct
measurement ofphosphorus pentoxide in the chamber and the pentoxide could have hydrolyzed to possibly less toxic constituents. On balance, none ofthe studies presented show that phosphorus pentoxide meets the toxicity criteria. Accordingly, EPA is removing the chemical from the EHS list.

VI. Regulatory Analyses

a.Executive Order12866

Under Executive Order 12866, (58 FR 51,735) ofOctober 4, 1993, the Agency must determine whether the regulatory action is "significant" and therefore subject to review by the Office of Management and Budget (OMB) and the requirements ofthe Executive Order. The Order defines "significant regulatory action" as one that is likely to result in arule that may:

(1) Have an annual effect on the economy of$100 million or more or adversely affect in a material way the economy, a sector ofthe economy, productivity, competition, jobs, the environment, public health or safety, or State, local or tribal governments or communities;

(2) Create a serious inconsistency or otherwise interfere with an action taken

or planned by another agency;

(3) Materially alter the budgetary impact ofentitlements, grants, user fees,

or loan programs or the rights and obligations ofrecipients thereof; or

(4) Raise novel legal orpolicy issues arising out oflegal mandates, the President's priorities, or the principles set forth in the Executive Order.

Ithas been determined that thisrule is not a "significant regulatory action" under the terms ofExecutive Order 12866 and is therefore not subject to OMB review.
b. RegulatoryFlexibilityAnalysis

Pursuant to the Regulatory Flexibility Act, 5 U.S.C. 601 et seq., whenever an agency is required to publish a notice of rulemaking for any proposed or final rule, itmust prepare and make available for public comment a regulatory flexibility analysis that describes the effect ofthe rule on small entities (i.e., small businesses, small organizations, and small governmentaljurisdictions). This analysis is unnecessary, however, if the agency's administrator certifies that the rule will not have a significant economic effect on a substantial number of small entities.

EPA has examined this rule's potential effects on small entities as required bythe Regulatory Flexibility Act. It has determined that today's final rule will not have a significant economic effect on a substantial number of small entities. The overall economic effect ofthisregulation has been determined to equate to 6,249 hours of burden reduction (with no added burden) at a total cost saving of $355,628 per year to allregulated entities. Therefore, this regulation will have a cost savings, and nothave a significant impact on small businesses. c. Paperwork ReductionAct
The information collection requirements contained in this final rule have been approved by OMB under the provisions ofthe Paperwork Reduction Act, 44U.S.C. 3501 etseq., and have been assigned OMB control number 2050-0092 (EPA Information Collection Request No. 1395.2). Copies ofthe information collection requests may be obtained from Sandy Farmer, OPPE Regulatory Information Division, U.S. Environmental Protection Agency (2136),401 M Street, SW., Washington, DC 20460 or by calling (202) 260-2740.

As indicated in the Section I Introduction, the mandatory reporting requirements under EPCRA section 304

serve as atrigger for informing state and local governments ofa release, so that state and local personnel can evaluate the need for any necessary action in a timely fashion. EPCRA section 304 also requires the submittal ofa written follow-up notice to the same state and local entities.

The public reporting burden for the collection ofinformation pursuant to EPCRA section 304 is estimated to take,

on average, 5 hours per response. This estimate includes the time required to make the call and to develop the written follow-up notice.

Because the RQs for almost all ofthe substances included in today's rule are to be raised, the net reporting and recordkeeping burden associated with reporting releases ofthese substances under EPCRA section 304 is expected to decrease. As demonstrated in an economic impact analysis (EIA), the Agency estimates that the total burden reduction for notification to SERCs and LEPCs, and notification to 911 services in transportation -related incidents, and the completion offollow up reports will equate to 6,249 hours at atotal cost savings of$355,628 per year.

Send comments on the ICR to the Director, OPPE Regulatory Information Division, U.S. Environmental Protection Agency (2136), 401 M Street, SW., Washington, DC 20460; and to the Office ofInformation and Regulatory Affairs, Office ofManagement and Budget, 725 17th Street, NW., Washington, DC 20503, marked "Attention: Desk Officer for EPA." Include ICR number 1395.2 in any correspondence.
d. UnfundedMandatesReform Act

Title II ofthe Unfunded Mandates Reform Act of 1995 (UMRA), Public Law 104-4, establishes requirements for Federal agencies to assess the effects of their regulatory actions on State, local, and tribal governments and the private sector. Under section 202 ofthe UMRA, EPA generally mustprepare a written statement, including a cost-benefit analysis, for proposed and final rules with "Federal mandates" that may result in expenditures to State, local, and tribal governments, in the aggregate,

or to the private sector, of$100 million

or more in any one year. Before promulgating an EPA rule forwhich a written statement is needed, section 205 ofthe UMRA generally requires EPA to identify and consider areasonable number ofregulatory alternatives and adopt the least costly, most costeffective or least burdensome alternative that achieves the objectives ofthe rule. The provisions of section 205 do not apply when they are inconsistent with applicable law. Moreover, section 205 allows EPA to adopt an alternative other than the least costly, most cost-effective

or least burdensome alternative ifthe Administrator publishes with the final rule an explanation why that alternative

was not adopted. Before EPA establishes any regulatory requirements that may significantly oruniquely affect small governments, including tribal governments, it must have developed under section 203 ofthe UMRA a small government agency plan. The plan must provide for notifying potentially affected small governments, enabling officials of affected small governments to have meaningful and timely input in the development ofEPA regulatory proposals with significant Federal intergovernmental mandates, and informing,educating, and advising small governments on compliance with the regulatory requirements.

EPA has determined that this rule does not contain aFederal mandate that mayresult in expenditures of$100 million or more for State, local, and tribal governments, in the aggregate, or the private sector in any one year. Because the RQs for almost all ofthe substances included in today's rule are to be raised, the net reporting and recordkeeping burden associated with reporting releases ofthese substances under EPCRA section 304 is expected to decrease. As demonstrated in an economic impact analysis (EIA), the Agency estimates that the total burden reduction for notification to SERCs and LEPCs, and notification to 911 services in transportation-related incidents, and the completion offollow up reports will equate to 6,249 hours at atotal cost savings of$355,628 per year. Thus, today's rule is not subject to the requirements of sections 202 and 205 of the UMRA.

EPA has determined that this rule contains no regulatory requirements that might significantly or uniquely affect

Because the RQs for almost allofthe substances included in today's rule are tobe raised, the net reporting and recordkeeping burden associated with reportingreleases of these substances under EPCRA section 304 is expected to decrease. Small governments will no longerreceive notifications and written follow-up reports from facilities thathave releases ofextremely hazardous substances less that the substances' TPQ.
