SUBCHAPTER C-AIR PROGRAMS

PART 52-APPROVAL AND PROMUL-GATION OF IMPLEMENTATIONPLANS

On April 30, 1971 (36 P.R. 8186), pur-suant to section 109 of the Clean AirAct, as amended, the Administrator pro-mulgated national ambient air qualitystandards for sulfur oxides, particulatematter, carbon monoxide, photochemicaloxidants, hydrocarbons, and nitrogendioxide. Within 9 months thereafter,each State was required by section 110of the Act to adopt and submit to theAdminitrator a plan which provides forthe implementation, maintenance, andenforcement of national ambient airquality standards within each air qualitycontrol region in the State. An additionalperiod of no longer than 18 months maybe allowed for adoption and submittalof that portion of a plan relating to im-plementation of secondary ambient airquality standards. State plans must pro-vide for attainment of national primaryambient air quality standards within 3years after the date of the Administra-tor's approval of such plans, except thata 2-year extension of this deadline maybe granted by the Administrator. Stateplans must provide for attainment of na-tional secondary ambient air qualitystandards within a reasonable time.Within 4 months from the date on whichState plans were required to be submit-ted, the Administrator must approve ordisapprove such plans or portionsthereof.

On August 14, 19.71 (36 P.R. 15486),the Administrator promulgated regula-tions (40 CFR Part 51) (formerly 42CPR Part 420, but transferred to ChapterI of Title 40 by publication in the FED-ERAL REGISTER, page 22369 et seq., No-vember 25, 1971) setting forth require-ments for preparation, adoption, andsubmittal of State implementation plans.These regulations were amended Octo-ber 23, 1971 (36 P.R. 20513), and Decem-ber 30, 1971 (36 P.R. 25233), to makecertain additions and corrections. TheAdministrator's regulations (40 CPR Part51) provided generally that State plansmust set forth a control strategy for at-tainment and maintenance of the na-tional standards; legally enforceableregulations and compliance schedules forimplementation of the control strategy;a contingency plan for preventing theoccurrence of air pollution levels whichwould cause significant harm to thehealth of persons; source surveillanceprocedures; procedures to assure thatconstruction or modification of sta-tionary sources will not interfere with at-tainment or maintenance of the nationalstandards; provisions for air quality sur-veillance; a description of the resourcesneeded to carry out the State plan; and

provisions for intergovernmental co-operation. Some of the r~qulrements varyby air quality control region in accord-ance with a classification scheme setforth in 40 CPR 51.9. Each State plan

-must also show that the State has thelegal authority necessary to carry outthe plan, as specified by 40 CPR 51.11.States were required to conduct one ormore public hearings prior to adoptionof their implementation plans.

All 50 States, plus the District of Co-lumbia, Puerto Rico, Virgin Islands,Guam, and American Samoa have sub-mitted implementation plans. The Ad-ministrator's approvals and disapprovalsare set forth below. A more detailed de-scription of disapproved portions, to-gether with an explanation of the basisof disapproval, will be provided to theStates; copies of these Evaluation Re-ports will be available for public inspec-tion at the Environmental 'ProtectionAgency, 401 M Street SW., Washington,D.C., and in the Agency's RegionalOffices.

Where the Administrator disapprovesa State plan or portion thereof, or wherea State fails to submit an implementa-tion plan or portion thereof, the Admin-istrator is required, under section 110(c)of the Act, to propose and subsequentlypromulgate regulations setting forth asubstitute implementation plan or por-tion thereof. Where regulatory portionsof a State plan, including controlstrategies and related rules and regula-tions, are disapproved or were not sub-mitted, regulations setting forth sub-stitute portions will be proposed .andpromulgated. When disapproved por-tions are of a nonregulatory nature, e.g.,air quality surveillance, resources, inter-governmental cooperation, and thereforeare not susceptible to correction throughpromulgation of regulations by the Ad-ministrator, detailed comments will beincluded in the evaluation report; insuch cases, the Environmental Protec-tion Agency will work with the Statesto correct the deficiencies.

To the extent possible, the Adminis-trator's evaluation of State plans reflectsthe latest information submitted by theStates. In the interest of giving Statesevery opportunity to bring their imple-mentation plans into full compliancewith the Act and 40 CER Part 51, theEnvironmental Protection Agency hasnotified States that modifications sub-mitted after the statutory'deadline forsubmittal.of State plans would be ac-cepted and considered: Provided, Thatsuch modifications were made and sub-mitted in accordance with the require-ments of 40 CPR Part 51. Accordingly,many States have been, and still are,making and submitting modifications oftheir implementation plans. Where suchmodifications affect the Administrator'sapproval or disapproval of a State planor portion thereof, but are not reflectedherein, appropriate changes to this partwill be published as soon as the Admin-istrator's evaluation of such modifica-tions is completed.

The Act directs the Administrator torequire a State to revise its implementa-tion plan whenever he finds that It is

substantially inadequate for attainmentand maintenance of a national standard.In accordance with the statutory man-date, the Environmental ProtectionAgency will make a continuing evalua-tion of the State plans and will, as nec-essary, call upon the States to makerevisions.

EVALUATION OF LEGAL AunIonnryStates were required to have the legal

authority specified In the Administra-tor's regulations. With one exception,States were required to have the speel-fled legal authority available to them atthe time they submitted their Imple-mentation plans. The one exception isauthority to carry out land-use andtransportation control measures; wherea State's control strategy include3 suchmeasures, the State plan must set fortha timetable for obtaining the necessarylegal authority. Where It was determinedthat a State's air pollution controlstatute does not explicitly provide allof the required legal authority, theState's attorney general was consultedfor an opinion as to whether the neces-sary authority is conferred by a generalgrant of powers In the air pollution con-trol statute or provided In other statutes.Where a State plan Indicated that oneor more local agencies will be responsi-ble for carrying out any portion of theimplementation plan, a similar ass es-ment was made of the legal authorityavailable to such local agencies. A com-plete record of the Environmental Pro-tection Agency's assessment of legal au-thority is maintained in the Office of theAssociate General Counsel, Air Qualityand Radiation Division, Rockville, Md,20852.

DELEGATION OF LEGAL AUTHORITY

The legal authority which each Statewas required to have carry out Its iniple-mentation plan Is specified by 40 CFR51.11. Subparagraphs (5) and (6) of§ 51.11 (a) require each State to have theauthority to obtain Information to deter-mine compliance with applicable lawsand regulations; require recordeplng;make inspections; conduct tests; requiresources to install and maintain monitor-ing equipment; require periodic report-ing; and release emission data to thepublic. The Administrator has suchauthority under section 114 of the Actand can delegate It to States. Where aState lacks the authority required by 40C R 51.11(a) (5) or (6), that portionof its implementation plan is disapprovedherein; however, if the State has re-quested delegation of the Administrator'sauthority, and if the State's source sur-veillance procedures are approvable, theneeded authority Is delegated herein,Where a State lacks the authority re-quired by 40 CPR 51.11(a) (5) or (6)but has not requested delegation of au-thority, the Administrator cannot ap-prove source surveillance procedureseven though the procedures may be tech-nically adequate. The State can correctthis deficiency by requesting a delegationof authority; such requests may be madeat any time and should be addressed tothe appropriate Regional Administrator.

ATTAn[mN Or' PamARY STANDARDS

" The Act requires attainment of pri-mary standards as expeditiously as prac-ticable, but not later than 3 years fromthe date of the Administrator's approvalof a State plan except where an exten-sion is granted by the Administrator; itrequires attainment of secondary stand-ards within a reasonable time. Exceptwhere extensions have been requested,State plans generally provide for attain-ment of the primary standards in 3 years.Whether more expeditious attainment ofthe primary standards is practicable is aquestion that will be subject to continu-ing examination in connection with theAdministrator's review of the complianceschedules and progress reports to be sub-mitted by the States and as part of theAdministrator's continuing surveillanceof State activities. It is already clear,

-however, that the aggregate emissioncontrol requirements of the 55 Stateplans will create such a great demand forclean fuels, emission control equipment,and other items that attainment of theprimary standards in many urban areasin significantly less time than 3 yearsgenerally will not be feasible.

ATTAINW DAsEach State plan must specify the pro-

jected dates of attainment of primaryand secondary standards. Where a Stateplan sets forth a control strategy andregulations adequate for attainment ofthe national standards within the timeperiods prescribed by the Act but fails tospecify an attainment date, the Admin-istrator will promulgate attainment datesmeeting the requirements of the Act.

MAlrMrAcE oF STANDARDSWhere existing air pollution levels ex-

ceed the national standards, State planswere expected to provide for the degreeof emission reduction necessary for at-tainment and maintenance of the na-tional standards, including the degree ofemission reduction necessary to offsetthe probable imp~act of projected growthof population, industrial activity, motorvehicle trafc, or other factors. There isa great deal of uncertainty involved inprojecting growth and predicting its im-pact on air quality. Growth projectionsextending more than 2 or 3 years intothe future are necessarily generalizedand inevitably are based on a variety ofassumptions, many of them which are, atbest, tenuous. Even where growth policieshave been adopted by State or localgovernments, they normally provide onlygeneral guidelines. Techniques for trans-lating, generalized projections of popula-tion and industrial growth into predic-tions of future air quality do not exist.Accordingly, States were limited in theextent to which they could develop con-trol strategies adequate not only for at-tainment, but also for maintenance, ofthe national standards. Since the Envi-ronmental Protection Agency's capabilityof planning for continued maintenanceof the national standards is subject to thesame limitations, and since State andlocal governments clearly should notlightly be deprived of the opportunity toplan and control growth In a manner best

suited to the needs and preferences of in-dividual communities and their Inhabi-tants, with due consideration of environ-mental impacts, the Administrator, atthis time, is not proposing substitute con-trol strategies based on considerationsrelated solely to maintenance of nationalstandards. States are required, however,to prevent construction, modification, oroperation of any stationary source at anylocation where its emissions will preventthe attainment or maintenance of anational standard; the Administratorwill promulgate appropriate regulationswherever State plans are Judged inade-quate in this regard. Thus, all Stateplans will include this mechanism forminimizing the effects of growth on airquality. New source performance stand-ards promulgated by the Administratorunder section 111 of the Act will alsoserve to minimize the impact of growth.Furthermore, the Act authorizes the Ad-ministrator to require revision of a Stateplan whenever he finds that it is substan-tially inadequate to attain or maintain anational standard. It is the Administra-tor's intention to make a continuing ex-amination of the adequacy of Stateplans, and, where necessary, to call forrevisions. States should be aware thatfailure to provide for maintenance of thenational standards could necessitate re-straints on population and industrialgrowth and/or further restrictions onemissions from existing sources of airpollution.

EVALUATION OP' CONTROL STRATEGMrA "control strategy" is a combination

of measures designed to achieve the ag-gregate reduction of emissions necessaryfor the purposes of attainment andmaintenance of a national standard.The Administrator's regulations (40CFR 51.13 and 51.14) set forth proce-dures, i.e., proportional or diffusionmodeling, to be employed by the Statesin demonstrating that their controlstrategies will be adequate for these pur-poses. Evaluation of the control strate-gies generally included assessment ofthe accuracy of the data relied upon bya State in demonstrating the adequacyof control strategies, the validity of anyassumptions made by the State, and theaccuracy of the calculations employedin the modeling exercises. In addition,a determination was made as to whetherthe control strategy would be suficientlycomprehensive.

SULMUR OxMDs AND PARTICULATE M&ATTRThe national standards for sulfur

oxides and particulate matter includeboth short-term standards, e.g., maxi-mum 24-hour concentrations not to beexceeded more than once per year, andlong-term standards, Le., annual aver-age concentrations. State plans were re-quired to set forth control strategies ade-quate for attainment and maintenanceof both the short-term and long-termstandards, with the exception of the 24-hour secondary standard for sulfur ox-ides and the annual average secondarystandard for particulate matter, both of'which are guidelines. Where State plansdid not explicitly demonstrate that a

10843

control strategy is adequate for attain-ment and maintenance of short-term, aswell as long-term standards, the Ad-ministrator has made judgments basedon available data regard peak-to-meanratios; point-source control measures, forexample, are likely to reduce the fre-quency and Intensity of peak concentra-tions. thus altering peak-to-mean ratiosand increasing the likelihood that a con-trol strategy adequate for attainment ofan annual average standard will also beadequate for attainment of short-termstandards.

FUEL AVArABn=

The State implementation plans tocontrol SOx generally have been respon-sive to the mandates of the Ciean AirAct. The plans provide for meeting by1975 primary air quality standards whichare designed to protect the public health.In most cases, the States determined1975 to be the "reasonable time" allowedby the Act to meet the secondary airquality standards for SOz which are de-signed to protect the public welfare. Fuelcombustion regulations were designed toachieve both the primary and secondarystandards by the 1975 date. n mostStates these emission regulations weremade to apply statewqlde, without re-gard to the differing air quality in re-gions within the State.

It is clear that achieving these rigor-ous State standards In the time pre-scribed would significantly enhance airquality in many areas of the Nation, ascontemplated by the Clean Air Act. How-ever, in addition to reviewing the effec-tiveness of each State implementationplan, this Agency and the Federal Gov-ernment have an obligation to assessthe impact of the various plans in theaggregate. From this standpoint, thereIs strong evidence that the completeimplementation of the plans as sub-.mitted may not be attainable in the timeprescribed.

Because of physical limitations on ourability to clean the emissions of highsulfur fuels on a large scale in the timepermitted by the statute, achievementof the particulars of the State planswould require the availability of largeadditional supplies of "clean!" fuels-natural gas and low sulfur coal and oil.Since fuel desulfurlzatlon facilities areunlikely to be built on the scale whichwould be required to fully implement allState plans by 1975. it appears that allState plans can be completely imple-mented by 1975 only with a major shortterm shift to naturally clean fuels. Un-fortunately, these naturally clean fuelsare not likely to be available In quantitiesnecessary to meet the projected demand.

Unfortunately, our long-overdue con-cern for air quality comes at a time whenthe abundance of cleaner energy fuels inthe United States is rapidly disappearingand energy experts are becoming worriedabout our ability to meet our energy fuelneeds even independent of environmen-tal considerations. Given the limits onthe supply of naturally clean fuels in theshort run, the well publicizedshortage ofnatural gas In this country, and thephysically disruptive task of substituting

FEDERAL REGISTER, VOL. 37, NO. 1OS-WEDNESDAY, M-'AY 31, 1972


the use of huge amounts of clean fuels byenergy producers and users at a timewhen traditional fuels such as naturalgas are in short supply, it is apparentthat the Nation faces a difficult task.

It is also apparent that the cost ofthis effort, translated into costs of fueland electric energy to our economy andto individual energy consumers, will besubstantial and cannot be wholly ig-nored. On the other hand, appropriateenviromental costs must be recognizedin the price of energy if we are to allo-cate our total resources properly.

There are alternative strategies which,should permit achievement of the goals

'of the Clean Air Act within the legisla-tive deadlines, but the approach must betwofold. First, implementation of thestandards must take into account thelimits on total availability of clean fuels.Second, government must also addressthe problem of creating economic andother incentives which ensure that nat-ural or desulfurized clean fuels go tousers in areas of greatest environmentalneed.

The Pure Air Act of 1972 (the sulfuremission tax), which is currently beforeCongress, is important to both aspectsof this approach. The tax would permitclean fuels to reach users in areas ofenvironmental need by providing astrong economic incentive for thoseusers to bid for the clean fuels. The taxwould also increase -the availability ofclean fuels by providing an economicstimulus both to develop new clean fuelresources, and to perfect technology forcleaning fuels before combustion, andfor purifying exhaust gases.

Preliminary analysis by EPA indicatesthe re.l possibility that, under currentconditions in the domestic and worldfuel markets including the absence ofthe sulfur tax, all aspects of the StatePlans In the aggregate cannot beachieved by 1975 despite the best effortsof both government and the privatesector. Pending further study, EPAis approving or promulgating regulationsfor meeting both the primary and sec-ondary SO% standards. The Statesshould proceed to develop complianceschedules on the assumption that bothstandards can be met. In the meantimeEPA will be completing its studies of theaggregate situation and will suggest nec-essary changes to the States, and like-wise modify federally promulgated soxregulations for achievement of the sec-ondary standard where appropriate.Highest priority must be given to achiev-ing the primary standards (health re-lated) by the statutory deadline.

At this time, the States most likely tobe affected by this shortage of clean fuelsinclude Illinois, Indiana, Kentucky,Wisconsin, Michigan, Ohio, Tennessee,Alabama, Pennsylvania, West Virginia,Georgia, and New York, but others willalso need to. consider the availability offuels in developing compliance schedules.

For its part in addition to completingthis work, EPA intends to be vigorousin urging other Federal agencies and theCongress to adopt energy policies whichwill stimulate the availability of-neededclean fuels and insure their availabilityto areas of greatest need, consistent with

environment, national security, con-sumer and other considerations.

'NITROGEN DIOXIDEWhere attainment of the national

standard for nitrogen dioxide would re-quire additional emission reductions be-yond those expected to result fromFederal motor vechicle emission stand-ards, the Admistrator's regulations (40CPR 51.14) required States to providefor the degree of nitrogen oxides emis-sion reduction 'attainable through theapplication of reasonably availabletechnology for the control of stationarysource emissions of nitrogen oxides, asdefined by 40 CFR. Part 51, AppendixB. Hydrocarbon emission reductionsarising from the Federal motor vehiclestandards or from transportation con-trol measures undertaken to implementthe national standards for photochemi-cal oxidants will tend to reduce ambientair concentrations of nitrogen dioxide.In accordance with 40 CFR 51.14, thiscombination of stationary and mobilesource control measures is consideredan adequate control strategy for imple-mentation of the national standards fornitrogen dioxide. Studies aimed at pro-viding an improved basis for developingand evaluating nitrogen oxides controlstrategies are underway. Based on theresults of these studies, the Administra-tor will determine whether revision ofthe State plans for implementation ofthe national standards for nitrogendioxide will be necessary; such revisionsmay necessitate, among other things, thedevelopment and application of nitro-gen oxides emission control techniquesgoing beyond those which are now avail-able. Pending such action, States' re-quests for 2-year extensions of thedeadline for attainment of this nationalstandard have not been evaluated.

HYDROCARBONS,The national standard for hydro-

carbons (40 CFR 50.10) is a guide to theformulation of control strategies for .at-tainment and maintenance of the na-tional standard for photochemicaloxidants. Accordingly, State plans werenot required to provide for' attainmentand maintenance of the national stand-ard for hydrocarbons, per se,

TRANSPORTATION CONTROL MEASURESThe Act and the Administrator's regu-

lations (40 CPR Part 51) require Statesto take steps to reduce emissions fromtransportation sources wherever suchsteps are necessary for attainment andmaintenance of national ambient airquality standards. In August 1971, whenthe Administrator's regulations werepromulgated, it was recognized thatStates have had practically no experi-ence with transportation control meas-ures as a means of dealing with airquality problems and that available datawere not sumcient to-permit States todevelop meaningful transportation con-trol schemes and predict their impact onair quality. The Environmental Protec-tion Agency had already begun an assess-ment of the extent to which varioustransportation control measures, includ-

FEDERAL REGISTER, VOL. 37, NO. 105-WEDNESDAY, MAY

Ing motor vehicle inspection and installa-tion of emission control devices on in-use automobiles, could be expected toproduce improvements in air quality, butit was apparent that the results wouldnot be available within the time allowedfor development of State plans. Accord-ingly, the States were advised that adop-tion of transportation control schemescould be deferred beyond the statutorydeadline for submittal of implementationplans but that State plans would haveto define the degree of emission reduc-tion to be achieved through transporta-tion control measures and Identify themeasures being considered. States werefurther advised that they would have tosubmit, no later than February 15, 1973,together with their first semiannualprogress reports, definitive transporta-tion control plans, including Identifica-tion of the specilflfc measures to be im-plemented, demonstration of the ade-quacy of these measures for attainmentand maintenance of the national stand.ards, and a detailed timetable for obtain-ing any necessary legal authority andtaking all other steps necessary to imple-ment the various measures. The Environ-mental Protection Agency, in cooperationwith the Department of Transportation,will provide assistance to the States inthe development of their transportationcontrol plans.

COMPLIANCE SCHEDULES

State plans were required to specifythe dates by which all sources must bein compliance with applicable regula-tions, except that, where a State planprovides for negotiating complianceschedules for individual sources, suchschedules are required to be submittedto the Administrator no later than thetime of submittal of the State's lrstsemiannual progress report. States gen-erally have either prescribed a terminaldate for compliance by all sources, withindiviiual source schedules, includinrschedules of incremental steps towardcompliance, to be negotiated, or havemade regulations effective almost imme-diately, with compliance schedules to benegotiated and effectuated through avariance procedure. Either approach isconsidered acceptable: Provided, flrst,That compliance with all regulationsrelated to attainment of national am-bient air quality standards will beachieved by the attainment date specifiedin the State plan or prwcrlbed by theAdministrator, and second, that provi-sion is made for negotiating complianceschedules, including incremental steps incases where the terminal date is morethan 18 months away.

EMERGENCY EPISODES

State plans were required to set forthepisode criteria, I.e., pollutant concen-trations at which specified emission con-trol actions will be initiated in order toprevent significant harm to the healthof persons. Episode criteria wore re-quired to be adequate to protect againstoccurrence of the significant harm levelsprescribed by the Administrator (40CPR 51.16). Emission control actionplans were required to provide for abate-

31, 1972

10844


ment adtion dealing with area sources.e.g., open burning, commercial and resi-dential incinerators, and motor vehicles,and to provide for development of indi-vidual standby abatement plans for allstationary sources emitting 1410 tons peryear or more. Where episode criteriadnd/or emission control action plans ap-plieable to area sources *and motor ve-hicles were not submitted or were dis-approved, the Administrator is notprescribing substitute provisions, but,rather, in carrying out his responsibili-ties under section 303 of the Act, will beguided by the suggested episode criteriaand emission control action plans setforth in the Administrator's regulations(40 CFR Part 51, Appendix L). Whereepisode criteria and/or emission controlaction plans are approved, the Adminis-trator will make use of them in theeventthat it is necessary to initiate actionunder section 303. In either case, the Ad-initrator, in acting under section 303,

may also take into consideration otherrelevant information and advice, includ-ing .medical-scientific opinions on en-dangerment to the health of persons.Where a State plan fails to provide forpublic announcements of episode stagesor fails to provide for development ofstandby abatement plans for station-ary sources emitting 100 tons per year ormore, the Administrator will promulgateregulations to correct such deficiencies.

AIR QuhnrrY SURVEILLANCEWhere a State'i provisions for air

quality surveillance do not meet the re-quirements of the Administrator's regu-lations (40 CFR 51.17), the deficiencieswill be identified in the evaluation re-port, and the Environmental ProtectionAgency will work with the State in cor-recting the deficiencies. Insofar as airquality monitoring methods are con-cerned, the only methods currently ap-proved are the reference methods pre-scribed by the Administrator (40 CPRPart 50) simultaneously with a promul-gation of the national standards. Withrespect to carbon monoxide, photo-chemical oxidants, and hydrocarbons,the Administrator prescribed an analyti-cal principle; any method employing ex-actly the same analytical principle isconsidered a reference method, providedthat it meets the performance 8pecifica-tions set forth in the Administrator'sregulations (40 CFR 51.17). For all pol-lutants, methods other than the refer-ence methods prescribed by the A-minis-trator may be approved if they areshown to be equivalent to the xeferencemethods. Equivalency testing guidelinesare being developed by the Environmen-tal Protection Agency.

NEW SOURCES AND MODIFICATIONS

State plans were required to providefor review of new sources and modifica-tions of existing sources and for prevent-ing construction or modification if itwould result in violations of applicableportions of a control strategy or inter-fere with attainment or maintenance ofnational standards.

REsouncEs

States were required by section 110 ofthe Act to provide assurances that theywill have adequate resources, I.e., per-sonnel and funding, to carry out theirimplementation plans. The Administra-tor's judgment as to the probable ade-quacy of projected resources is basedon a number of considerations, includ-ing estimates of manpower needs in re-lation to factors affecting the nature andmagnitude of air pollution problems andprevious evaluations of the performanceof State and local air pollution controlagencies. Where it is the Administrator'sjudgment that a State's projected re-sources may be inadequate, the Environ-mental Protection Agency will work withthe State in correcting this deficiency.The Administrator's judgment on theadequacy of resources should not be con-strued as a commitment to provide fi-nancial support; such support is subjectto the limitations of funds appropriatedunder the Clean Air Act.

Two-YEAR EXTENSIONSThe Act provides for 2-year, or shorter,

extensions of the statutory deadline forattainment of national primary ambientair quality standards where needed tech-nology or other alternatives are not avail-able or will not be available soon enoughto permit attainment of the primarystandards witlin the 3-year period pre-scribed by the Act. For the most pat,States' requests for such extensions wererelated to identified needs for applica-tion of transportation control measures.The Administrator has determined thatthe leadtime necessary for development,adoption, and implementation of trans-portation control measures generallyprecludes their application on any signif-icant scale within the next 3 years, i.e.,they will not be available soon enough topermit attainment of the primary stdnd-ards within the time period prescribed bytheAct. This determination was reflectedin 40 CFR 51, in which emission controlmeasures applicable to mobile sources,with minor exceptions, were not Includedamong the various emission controlmeasures judged to be attainable withreasonably available technology. Accord-ingly, it is the Administrator's judgmentthat 2-year extensions are Justified incases where transportatior control meas-ures will be necessary. It should be em-phasized, however, that timetables forattainment of primary standards will besubject to continuing examination, and,where the Administrator finds that moreexpeditious attainment is practicable,States will be required to revise theirtimetables.

-Where States have submitted imple-mentation plans that do not provide forattainment of the primary standardswithin the 3-year period prescribed bythe Act and have not requested an exten-sion, the Administrator has evaluatedsuch State plans to determine whetheran extension is Justified under the pro-visions of the Act. The Administrator'sdeterminations in such cases are re-flected below; these determinations wll

also be subject to continuing examina-tion, and where necessary, revision.

ErGHvEW-MoNr= ExTmsrsoxsUnder the Act, the Administrator may,

wherever he determines necessary, ex-tend for a period of not more than 18months the deadline for submittal of aState plan or portion thereof which wouldimplement a national secondary stand-ard. 40 CFR 51.31 provides that such ex-tensions may be granted where attain-ment of a secondary standard will re-quire emission reductions exceeding thosewhich can be achieved through the appli-cation of reasonably available controltechnology, as defined in 40 CFR Part 51,Appendix B. Where a State plan fails toprovide for attainment of a secondarystandard, and where attainment wouldrequire emission reductions exceedingthose which can be achieved through theapplication of reasonably available con-trol technology, the Administrator Isproviding for an 18-month extension re-gardless of whether the State has re-quested one. Such extensions will be ap-plicable to adoption of an adequate planfor implementation of the secondarystandard by the State or promulgation ofan adequate implementation plan by theAdministrator.

Emisom DATA AvrAmnyThe Act requires assurance that States

will provide for public availability ofemission data. Where a State lacks legalauthority to obtain and/or release emis-sion data or where the State plan is de-ficient with respect to source-reportingrequirements or procedures for publicaccess to emission data, the Administra-tor is disapproving the pertinent provi-slons of the State plan. The Administra-tor will promulgate regulations to remedysuch deficiencies. Under section 114 ofthe Clean Air Act, States may requestdelegation of the Administrator's author-ity to obtain and release information.

SouRcz MONTORINGStates must have legal authority to

require stationary source owners or oper-ators to install, maintain, and use emis-sion monitoring devices. The Environ-mental Protection Agency is making ananalysis of the Performance of currentlyavailable emission (in-stack) monitor-ing devices. Accordingly, States were notrequired by 40 CFR Part 51 to imposespecific source-by-source requirementsfor in-stack monitoring at this time.

OiIONAL CONTROLSeveral State plans include regula-

tions under which a source owner oroperator could be exempt from compli-ance with an applicable emission limi-tation if he can show that emissionsfrom the source will not interfere withattainment or maintenance of the na-tional standards. The Administratorneither approves nor disapproves suchoptional control features. States are ad-vised, however, that action taken toallow any such exemptions will con-stitute revision of a State plan and

FEDERAL REGISTER, VOL 37, NO. 105-WEDNESDAY MAY 31, 1972

108,5

10846

therefore will be subject at that time tothe Administrator's approval

REVISIONSIn accqrdance with the Act and the

Administrator's regulations (40 CFR51.6), all State plans are subject to re-vision, as necessary, to take account ofrevisions of the national standards,availability of improved or more ex-peditious methods of attaining the na-tional standards, or a finding by theAdministrator that a State plan is sub-stantially inadequate to attain or main-tain a national standard. Accordingly,whether a State has acknowledged thatits implementation plan is subject to re-vision is considered immaterial.

ENFORCEMENTUpon approval by the Administrator,

a State plan is enforceable by the Ad-ministrator under the Clean Air Act. Allapproved provisions relating to attain-ment and maintenance of nationalstandards, including approved rules andregulations, are subject to such enforce-ment action. Where a State plan includesregulations designed to attain and main-tain air quality better than that requiredby the national standards, such regula-tions are subject to enforcement actionunder the Clean Air Act unless they areseparate fiom those necessary for at-tainment and maintenance of the na-tional standards.

PRoGREss REPORTSStates are required to submit semi-

annual reports on their progress in car-rying out approved implementation plansor portions thereof. For implementationplans approved herein, the first progressreports will be due February 15, 1973.A format for use in preparing and sub-mitting such reports is being preparedand will be made available to the States.

PasvIous APPROVALS

The State implementation plans ap-proved 'herein supplement the portionspreviously approved by the Administra-tor, notice of which was published Feb-ruary 3, 1972 (37 F.R. 2581), at Part 52of Title 40 of the Code of Federal Regu-lations. Portions of State plans whichhave previously been approved remainin effect and unaffected by the approvalspublished today.

SCOPE OF APPROVALS

In general, all portions of State planswhich are related to attainment andand maintenance of national standardsare apl roved unless specifically dis-approved herein.

JUDICIAL REVIEW

The Administrator's approval or pro-mulgation of implementation plans, orportions thereof, is subject to judicial re-view under section 307(b) (1) of theClean Air Act. For purposes of section307(b)(1), the .30-day period withinwhich a petition for review may be filedwill be considered to run from the dateof publication in the FEDERAL REGISTERof a notice of approval or promulgationof a plan or portion thereof.


NOTE

Subpart A of the regulations includesgeneral statements regarding the type ofprovisions which will be promulgatedby the Agency as necessary in varioussubparts. These statements are expressedin the present tense in order to avoid re-visions of verb tenses at the time ofpromulgation.

EFFECTIVE DATEThese regulations are effective on the

date of their publication in the FEDERALREGISTER (5-31-72). The Agency findsthat good cause exists for not publishingthese regulations as a notice of proposedrule making and for making them effec-tive immediately upon publication, forthe following reasons:

1. The implementation plans were pre-pared, adopted, and submitted by theStates, and reviewed and evaluated bythe Administrator pursuant to 40 CFRPart 51, which, prior to promulgation,had been published as a notice of pro-posed rule-making for comment by in-terested persons, and

2. The approved implementation planprovisions were adopted In accordancewith procedural requirements of Stateand Federal law, which provided for ade-quate public participation through no-tice, public hearings, and time for com-ment, and consequently further publicparticipation is unnecessary.(42 U.S.C. 1857C-5)
