AGENCY: Environmental ProtectionAgency (EPA). ,ACTION: Proposed regulation.

SUMMARY: EPA proposes modificationsto the regulation which limits effluentdischarges to waters of the UnitedStates and the introduction of pollutantsinto publicly owned treatment worksfrom facilities engaged in ma'nufacturingiron and steel. EPA agreed to proposethese modifications in a settlementagreement which resolved the variouslawsuits brought against EPA by thesteel industry and the Natural ResourcesDefense Council, Inc., challenging thefinal iron and steel industry regulationpromulgated by EPA on May 27, 1982, 47FR 23258.

The proposed modifications include:(1) An amendment to the "waterbubble" rule (an alternate effluentlimitations policy, under whichdischargers with multiple outfalls maydischarge greater amounts of pollutantsfrom outfalls where treatment costs arehigh in exchange for an equivalentdecrease from outfalls at the same plantwhere abatement is less expensive); (2)certain modifications of the effluentlimitations for "best practicable controltechnology currently available: (BPT);"best available technology economicallyachievable" (BAT); "best conventionalpollutant control technology" (BCT);and, "new source-performancestandards" (NSPS) for direct discharges;and (3) certain modifications to thepretreatment standards for new and'existing indirect discharges (PSNS andPSES). In addition, EPA agreed topropose additional preamble languageregarding the steel industry regulation.The Agency is also proposing anamendment to the General PretreatmentRegulations (40 CFR Part 4.03) whichpermits reclassification of non-contactcooling water flows contaminated withsignificant quantities of pollutants from"dilute" to "unregulated" for purposes ofthe combined waste stream formulacontained in 40 CFR 403.6(e).DATES: Comments on this proposal mustbe subrmitted on or before November 14,1983.ADDRESSES: Send comments to: Mr.Ernst P.

I. Legal Authority

The regulation described in this noticeis proposed under authority of sections301, 304, 306, 307, and 501 of the CleanWater Act (the Federal Water PollutionControl Act Amendments of 1972, 33W.S.C. 1251 et seq., as amended by theClean Water Act of 1977, Pub. L. 92-517).

1I. Background

A. Prior Regulation

On January 7, 1981, EPA proposed aregulation to establish Best PracticableControl Technology Currently Available

(BTP), Best Available TechnologyEconomically Achieveable (BAT, andBest Conventional Pollutant ControlTechnology (BCT) effluent limitationsand New Source Performance Standards(NSPS), Pretreatment Standards forExisting Sources (PSES), andP etreatment Standards for NewSources (PSNS) for the iron and steelmanufacturing point source categoryPSES, and PSNS for the iron and steelmanufacturing point source category(steel industry), 46 FR 1858. EPApublished the final steel industryregulation on May 27, 1982, 47 FR 23258.The preamble to the final steel industryregulation describes the history of therulemaking action.

B. Challenges to the Prior Regulation

After publication of the steel industryregulation, certain members of the steelindustry, the American Iron and SteelInstitute, and the Natural ResourcesDefense Council, Inc., filed petitions toreview the regulation. These challengeswere consolidated into one lawsuit bythe Third Circuit Court of Appeals.(National Steel Corp. v. EPA, No. 82-3225 and Consolidated Cases).

C. Settlement Ageement

(1) Agreement to Modifications andChanges. On February 24, 1983, the-parties in the consolidated lawsuitsentered into a comprehensive settlementagreement which resolved all issuesrelated to the steel industry regulationraised by the petitioners. As a result ofthat settlement agreement, the UnitedStates Court of Appeals issued an orderon March 9, 1982 which stayed briefingin the lawsuits. In the settlementagreement, EPA agreed to publish anotice of proposed rulemaking and tosolicit comments regarding certain,modifications to the final steel industryregulation. In addition, EPA agreed topublish proposed additons to thepreamble to the regulation. If, after EPAhas taken final action under thesettlement agrepement, each individualprovision of the final steel industryregulation and each addition to thepreamble is substantially the same as,and does not alter the meaning of,Janguage set forth in the settlementageement, the petitioners will dismissthe various lawsuits challenging thefinal steel industry regulation

EPA also agreed to take final actionon a proposed amendment to the generalpretreatment regulations (40 CFR Part403) which would allow reclassification

.of non-contact cooling waterscontaiminated with significantquantities pollutants from "dilute" to"unregulated" for purposes of the

46944


combined waste stream formula to 40CFR 403.6(e).

(2) Stay of Certain EffluentLimitations. As part of the SettlementAgreement, the parties jointly requestedthe United States Court of Appeals forthe Third Circuit in National Steel Corp.v EPA, to stay the effectiveness ofcertain sections of 40 CFR Part 420pending final action by EPA on eachrespective modification or additon.Copies of the settlement agreement werepromptly sent to EPA Regional Officesand State NPDES permit-issuingauthorities after it was executed. OnMarch 9, 1983, the Court entered anorder staying those sections of theregulation promulgated on May 27, 1982which EPA is proposing to amend.

All limitations and standardscontained in the final steel industryregulation published in May 27, 1982which are not specifically listed in theattached proposed regulation are notstayed by the order entered by the court.EPA is not proposing to delete or modifyany of those limitations and standardsin this notice.

IIl. Proposed Modifications to the Ironand Steel Manufacturing Point SourceCategory Regulation

The following are the changes to thesteel industry regulation EPA isproposing:

A. Section 420.03 Alternative EffluentLimitations (Water Bubble)

The proposed amendments to thewater bubble rule for the iron and steelmanufacturing point source categoryregulation provide that the alternativeeffluent limitations established underthe water bubble must result in adecrease in the discharge of tradedpollutants from the amount allowed bythe generally applicable limitations. Thewater bubble rule established by thefinal regulation published on May 27,1982, provided that there could be noincrease in the discharge of pollutantsbeyond that allowed by the generallyapplicable limitations. The preambleamendments presented in Section V ofthis notice describes the proposedrevisions to the water bubble rule.

In the settlement agreement, theAgency agreed to propose to amend thepreamble to the regulation as follows:

As part of the settlement, EPA is proposingto amend its bubble rule for the steelindustry. As originally promulgated, the ruleprovided that a discharger could qualify foralternative effluent limitations as long as itsdischarge from a combination of outfalls metcertain requirements (water qualitystandards) and restrictions and would notexceed the total mass of each pollutantotherwise'allowed under the, regulation.

Under the revised rule being proposed today,a discharger would have to meet the samerequirements and restrictions, but wouldqualify for alternative effluent limitationsonly if it achieves a net reduction from thetotal mass of each traded pollutant.

The amended regulation provides that thepermit-issuing authority must determine an"appropriate net reduction amount" in eachcase. In making that determination, it isintended that the permit writer will examinehistorical discharge levels and seek toachieve those reductions that are attainableat a facility through good engineeringpractices, improved operations andsupervision of existing treatment systems orother feasible modifications, e.g., non-processflow segregation or chemical addition, if theycan be achieved without requiring significantadditional expenditures. It is intended that inreviewing opportunities for appropriatereductions, the permit writer will require onlythose measures which result in non-trivial(substantial) effluent reductions and whichwill not require significant additionalexpenditures.

The minimum net reduction in all cases foreach pollutant traded is to be the amountspecified in the regulation. The amount isexpressed in terms of percentages of theamount by which a discharger proposes toexceed the otherwise applicable effluentlimitations established in this regulation. TheAgency proposes approximately 15 percentfor Total Suspended Solids (TSS) and Oil andGrease lO&G) and approximately 10 percentfor all other traded pollutants.

In the simplest case, for example, adischarger might propose-to exceed theallowable limitation for TSS on Outfall A by100 pounds and then make up the amount onOutfall B by reducing its allowable dischargeby 100 pounds. The net reduction provisionwould require that, at a minimum, the "allowable discharge from Outfall B (or anyother outfall which the discharger hasincluded in the bubble trade) be reduced byapproximately 115 pounds. In making adetermination of the "appropriate netreduction amount," the permit writer willrequire further, non-trivial (substantial)reductions only if he determines that they canbe achieved without significant additionalexpenditures.

This amendment results from settlement oflitigation among several parties withsignificantly divergent views of the waterbubble rule. This provision does notrepresent the Agency view on whether it iseither a legally required condition of a bubblerule under the Clean Water Act or any otherenvironmental statute or required as a matterof policy, nor shall it be taken as an indicatorof what the Agency may or may not requireIn any other regulations establishing effluentlimitations guidelines under the'Clean WaterAct.

In reaching this accord, the parties do notimply any changes in their positions. In theinterest of avoiding protracted litigation andof expediting the installation of pollutioncontrols-for this industry, the parties havereached an overall settlement of many issuesthat they view as beneficial. In that context,the parties have-agreed to resolve theirdifferences'with this settlement.-

B. Section 420.06 Removal Credits forPhenols (4AAP

EPA proposes to add § 420.06 whichspecifies that pretreatment removalcredits for phenols (4AAP) may begranted when phenols (4AAP) is used asan indicator or surrogate pollutant..Under the general pretreatmentregulations, a categorical pretreatmentstandard may be revised to reflectremoval of indicator or surrogatepollutants if the standard specifies thatsuch revisions are permissible (40 CFR403.7(a)). The final regulation publishedon May 27, 1982, did not specify thatremoval credits would be granted forphenols (4AAP). The Agency believesthat the biological treatment systemsemployed at publicly owned treatmentworks will, in large measure, removethose pollutants for which phenols(4AAP) is Used as an indicator polluta ntto the same degree as they removephenols (4AAP). Accordingly, EPAproposes to revise the steel industryregulations to provide that removalcredits maybe granted for phenols(4AAP).


Removal allowances pursuant to 40 CFR403.7(a)(1) may be granted for phenols(4AAP) limited in 40 CFR Part 420 when usedas an indicator or surrogate pollutant. Ofcourse, when phenols (4AAP are not used asan indicator or surrogate pollutant, removalallowances may also be granted.

C. Subparts B and C-Sintering andIronniaking Subcategories

The proposed BAT, NSPS, PSES, andPSNS ironmaking and sinteringlimitations and standards for lead andzinc are slightly higher than thosecontained in the final steel industryregulation published on May 27, 1982.After promulgating the final regulation,EPA learned that the final limitations forironmaking operations (blast furnaces)were based in part upon data obtainedat a plant with treatment operationsmore extensive than the EPA modeltreatment system. Therefore, these datamay not be an appropriate basis for thelimitations and standards. The'limitations and standards proposedtoday are based upon data obtainedfrom steelmaking operations using theapplicable BAT model treatment system.The model treatment systems used todevelop the limitations and standardsfor steelmaking operations are the sameas those considered for sintering andironmaking operations. Becausewastewaters from steelmakingoperations are similar in character andtreatability to wastewaters from,

46945

Federal Register / Vol.,48, No. 200 / Friday, October 14, 1983 . Proposed Rules

sintering and ironmaking operationswith respect to toxic metal pollutants,the Agency believes that it isappropriate to rely upon that data inproposing modified lead and zinclimitations and standards for sinteringand ironmaking operation. Volume I ofDevelopment Document (EPA 440/1-82/024, May 1982, pages 13, 18, 19, 27, 31, 34,35, 40, 41, 46, 51, 55, 59, 63, 64, 66-68, and409-427) contains the relevant datarelating to steelmaking operations.

EPA is proposing modifications to theBAT limitations and PSES for totalcyanide and to establish a newsubdivision for existing indirect blastfurnace dischargers which wouldcontain standards which are the sameas the generally applicable PSES exceptthat the proposed ammonia-N andphenol standards are less stringent.These standards are only applicable tothe two existing iron blast furnaceoperations which discharge theirwastewater into POTWs. These,operations are located in Chicago,Illinois and discharge their wastewaterinto the Metropolitan Sanitary Districtsystem. Compliance with the proposedcyanide BAT limitations and PSES couldbe accomplished through the use ofwastewater treatment technologiesother than the model BAT and PSESalkaline chlorination technology. Theproposed changes would, accordingly,give the industry added flexibility. EPAis not, however, proposing any changesto the BAT limitations and p'retreatmentstandards (except as noted above forexisting indirect dischargers) forammonia-N and phenols (4AAP)contained in the final regulation.

D. Section.301 (g) W/Vater QualityVariance for Ammonia-N and Phenols(4AAP)

The availability of variances from theBAT limitations for non-toxicnonconventional pollutants as allowedunder Section 301(g) of the Clean WaterAct can significantly affect the cost ofcompliance for a discharger. Section301(g) variances can, however, only begranted in cases where the granting ofthe variance will not interfere withattainment of existing water qualitystandards. Certain parties to theSettlement Agreement have sought aclarification regarding the availability ofSection 301(g) variances for steelindustry dischargers. In the SettlementAgreement, the Agency agreed topropose to amend the preamble to thefinal regulation as follows:

The BPT referred to in section 301(g) of theClean Water Act is either (a) the requirementapplicable to the facility as a result of theBPT limitation contained in the steel industryregulation, or (b) the requirement applicable

to a facility as a result of the BPT limitationcontained in the steel industry regulationwhich is or may be modified after February24, 1983 by a futidamentally different factors('TDF") variance, (40 CFR 1"25.31), or the net/gross provisions of the NPDES permitregulationi (40 CFR 122.63(h). Section 301(g)variances may be granted for ammonia-Ndischarges from blast furnaces and fromsinter plants when sinter plant wastewatersare treated with blast furnace wastewaters.Section 301(g] variances may also be grantedfor phenols (4AAP) discharges from blastfurnaces and from sinter plants when sinterplant wastewaters are treated with blastfurnace waters if the applicant dischargingphenols performs appropriate analyses (e.g.,CC or CC/MS) of the effluent whichdemonstrate that the effluent does notcontain significant amounts of toxicpollutants. Of course, no variance may begranted pursuant to section 301(g) unless thedemonstration cal!ed for by that section hasbeen made.

E. Blast Furnace Flow-Rated SafetyIssue


It las been brought to the Agency'sattention that one facility contends that itmay encounter a safety problem related tothe maintenance of gas seal pressuresresulting from efforts to reduce its blastfurnace flows to those contemplated by theEPA model. Such a safety related flowproblem may result in difficulty in meetingblast furnace mass limitations at the facility.Safety related issues were not raised prior topromulgation of the effluent limitationsguidelines and were, therefore, notconsidered by the Agency in the rulemaking.The Agency has not received any informationthat this may be a problem at any otherfacility. If it appears that there is a safetyproblem at that particular site related to flowreduction (or the total cost of compliancewith the BAT requirements, including the costof remedying the safety problem is-substantially reater than the EPA modeltreatment system cost estimate) then either orboth of those circumstances may be anappropriate basis for a FDF variance for thatfacility. Any application for such a varianceshall be in accordance with and satisfy therequirements of 40 CFR Part 125 Subpart D.

F. Subpart I-Acid PicklingSubcategory, Sulfuric and HydrochloricAcid Pickling Segments

In accordance with the settlementagreement, the proposed BPT and BATlimitations and NSPS, PSES, and PSNSfor zinc are slightly higher than thosecontained in the final regulation.

G. Subpart I-Cold FormingSubcategory, Cold Worked Pipe andTube Segrhents

The final regulation limited all coldworked pipe and tube operations to zero

-discharge at each level of treatment

(BPT, BAT, NSPS, PSES, PSNS, andBCT). The model treatment systemrelied upon by the Agency as the basisfor the final limitations and standardsincludes the recycle of the oil or watersolution and, when appropriate, contracthauling of a small oil solutionblowdown" The proposed regulationwould permit nominal discharges of thespent oil or water solution (rather thancontract hauling), and also specifies thatappropriate limitations and standardsfor process wastewaters which are notregulated by the prior regulation are tobe developed on a case-by-case basis.The proposed effluent limitations andstandards for cold worked pipe and tubeoperations are based upon the coldrolling model treatment systems and amodel flow rate of 5 gallons per ton.

H. Subpart L-Hot Coating SubcategoryThe proposed regulation contains

modified effluent limitations andstandards for zinc. These limitationsand standards are based upoq the sameeffluent concentration as are theproposed zinc limitations and standardsfor acid pickling operations (0.20 mg/I).The proposed regulation contains aprovision requiring that hot coatingtreatment facilities presently achievingzinc discharge levels more stringentthan the proposed limitations andstandards continue to do so. Theproposed regulation also provides thatthe proposed limitations may be used asa basis for determining alternativelimitations under 40 CFR 420.03 (waterbubble rule) even for those facilitiespresently achieving discharge levelsmore stringent than the proposedlimitations and standards.

IV. Proposed Amendments to thePreamble to the Regulation

A. Pretreotment Issues

(1) Flow Monitoring for CombinedWastestream Formula. In the settlementagreement, the Agency agreed topropose to amend the preamble to theregulation as follows:.

Under 9 403.12(b)(4) of the GeneralPretreatment Regulations. a facility mustmonitor the flow of regulated process streamsand other streams "as necessary" to allowuse of the Combined Wastestream Formula.A facility must monitor the flows of itsregulated streams. However, a facility canavoid monitoring its other streams(unregulated and dilute) under this section byagreeing to meet a mass limitation at least asstringent as the one which would becalculated under the Combined WastestreamFormula if these other streams were takeninto consideration. An integrated iron andsteel facility combining regulated processstreams with either unregulated or dilutestreams, or both, can avoid monitoring the

46946


flows of those streams if it agrees to meet themass limit calculated solely through use ofthe limits applicable to the regulated streams.Such a limit would be as stringent as anywhich could possibly be'derived under theformula if either the unregulated or dilutestreams, or both, were taken intoconsideration. If, however, the facility desiresto take into account potential pollutantscontained in these unregulated or dilutestreams, monitoring of these streams will berequired to enable calculation of thealternative limit under the formula.

It should be noted that it.is an entirelydifferent matter where concentration-basedrather than mass-based limits are involved. Afacility cannot, for example, avoid monitoringunregulated or dilute streams by agreeing tomeet the concentration limit applicable to itsregulated streams. This is becauseapplication of the formula could result in amore stringent concentration-based limit ifthe unregulated or dilute streams were-takeninto consideration.

(2) Monitoring Data for TemporarilyClosed Plants. In the settlementagreement, the Agency agreed topropose to amend the preamble to theregulation as follows:

The pretreatment regulations should beconstrued to establish that temporarily closedplants are required to submit a-baselinemonitoring report if recommencement ofdischarge is expected, but need not includethe monitoring information unless the plantwants to submit historical data and this isacceptable to the Control Authority.Monitoring data should be submitted within areasonable time after reopening the plant. Forthose plants that are operating at a reducedrate of production, a complete baselinemonitoring report is required. The reportshould include monitoring data based uponthe present average rate of production. If theplant calculates its limits through use of theCombined Wastestream Formula, it will benecessary to inform the Control Authority ofany significant change in the values used tocalculate this limit. See 40 CFR 403.6(e)(1982).

(3) Flow Estimates for CombinedWastestream Formula. In the settlementagreement, the Agency agreed topropose to amend the preamble to theregulation as follows:

Flows from integrated facilities can beestimated when it is difficult or nearlyimpossible to monitor the flows to achieve anactual reading. 40 CFR 403.12(b)(4) (1982) liststhe flow measurement requirements, andstates in part that "the Control Authority mayallow for verifiable estimates of these flows[regulated streams and other streamsnecessary to allow use of the CombinedWastestream Formula] where justified bycost of feasibility considerations."

(4) Mass-Based and Concentration-Based Pretreatment Standards. In thesettlement agreement, the Agencyagreed to propose to amend thepreamble to the regulation as follows:

If an integrated plant is required tQ complywittl a categorical pretreatment standardexpressed only in the mass-based limits andwith another categorical pretreatmentstandard expressed only in concentration-based limits, a mass-based limit should beapplied to the combined flow. To accomplishthis under the formula, the concentrationlimit may be converted to a mass limit bymultiplying fhe concentration limit by theaverage or other appropriate flow of theregulated stream to which that. limit applies.

B. Central Tieatment


Industry petitioners believe that they areentitled to obtain a FDF variance under 40CFR Part 125 Subpart D for an individualprocess (a) where the removal costs arewholly out of proportion to the removal costsconsidered during development of thenational limits, or (b where other factorssolely related to, that individual processwould result in a non-water qualityenvironmental impact (including energyrequirements) fundamentally more adversethan the impact considered duringdevelopment of the national limits, eventhough EPA may have considered such costsor such other factors in making itsdetermination pursuant to 40 CFR 420'01(b).EPA does not concede that petitioners'contention is a correct interpretation ofapplicable law, but does rot agree that thediscussion in the preamble (47 FR 23267(Column 3) (May 27, 1982)) was not intendedto preclude this contention.

V. Proposed Modification to the GeneralPretreatment Regulations, § 403.6(c)

In the combined wastestream formula,the term "dilution stream" is defined toinclude boiler blowdown and non-contact cooling water streams, amongothers. However, in certaincircumstances (e-g, where recycledcooling water is tfeated with algaecides)non-contact cooling water or boilerblowdown could contain significantconcentrations of regulated pollutants.The Agency today proposes to refine themeaning of dilution stream to addressthis situation. Where non-contactcooling water or a boiler blowdownstream contains a significant amount ofa pollutant, and an industrial usercombines this wastewater with itsregulated process wastestream(s) priorto treatment, resulting in a substantialredution of that particular pollutant,the Control Authority will be authorizedto exercise its discretion to classify thisstream as either a dilution or anunregulated stream. The term "ControlAuthority" refers either to the POTW ifit has an approved pretreatmentprogram, or to the Approval Authority(EPA or the NPDES State) if the POTWhas no approved program.

. Before the Control Authority canexercise its discretion to classify such-astream, the industrial user must provideengineering, production, and samplingand analysis information sufficient toallow a determination by the ControlAuthority on how the stream should beclassified.

VI. Environmental Impact of theProposed Modifications to the SteelIndustry Regulation

EPA's estimates of the industry-widedirect discharges of toxic metals andtotal cyanide under the final steel.industry regulation and the regulation asmodified by this proposal are presentedbelow. Volume I of the DevelopmentDocument contains a compilation ofestimated industry-wide discharges on asubcategory specific basis. Theestimated discharges of other pollutantslimited by the final steel industryregulation would be the same under theregulation as modified by this proposal.These estimates do not take intoaccount the proposed change in thewater bubble rule which would result ina decrease in the. amount of pollutantsdischarged at those facilities using therule.

EPA invites public participation inthis rulemaking and requests commentson the proposals discussed or set out inthis notice. The Agency asks that anydeficiencies in the record of thisproposal be pointed to with specificityand that suggested revisions orcorrections be supported by data.

VIII. Executive Order 12291

Under Executive Order 12291, EPAmust judge whether a regulation is"major" and therefore subject to therequirement of a Regulatory ImpactAnalysis. The Agency previouslyprepared such an analysis regarding theMay 27, 1982 final steel industryregulation. This pioposed regulation isnot major because it does not fall withinthe criteria for major regulationsestablished in Executive Order 12291.

IX. Regulatory Flexibility Analysis

Under the Regulatory Flexibility Act, 5U.S.C. 601 et seq., EPA must prepare aRegulatory Flexibility Analysis for allproposed regulations that have asignificant impact on a substantialnumber of small entities. In thepreamble to the May 27, 1982 final steelindustry regulation, the Agencyconcluded that there would not be asignificant impact on any segment of theregulated population, large or small. Forthat reason, the Agency determined thata formal regulatory flexibility analysiswas not required. That conclusion isequally applicable to this regulation.The Agency is not, therefore, preparinga formal analysis for this regulation.

X. OMB Review

This regulation was submitted to theOffice of Management and Budget forreview as required by Executive Order12291. Any comments from OMB to EPAand any EPA response to thosecomments are available for publicinspection at Room M2404, U.S. EPA,401 M Street, S.W., Washington, D.C.20460 from 9:00 a.m. to 4:00 p.m. Mondaythrough Friday, excluding Federalholidays.

Dated: September 27, 1983.William D. Ruckelshaus,.Administrator.

For the reasons set out in thepreamble, EPA is proposing to amend 40CFR Part 420 as follows:

PART 420-(AMENDED]

1. The authority citation for Part 420reads as follows:

Authority: Sections 301: 304 (b), (c), (e), and(g): 306 (b) and (c); 307; 308 and 501, CleanWater Act (the Federal Water PollutionControl Act Amendments of 1972, asamended by the Clean Water Act of 1977)(the "Act"): 33 U.S.C. 1311: 1314'(b), (c), (e).and (g): 1316 (b) and (c): 1317: 1318; and 1361:86 Slat. 816, Pub. L. 92-500 91.Slat. 1567: Pub.L. 95-217.

2. By revising § 420.03 to read asfollows:

§ 420.03 Alternative effluent limitationsrepresentirg the degree of effluentreduction attainable by the application ofbest practicable control technologycurrently available, best availabletechnology, and best conventionaltechnology.

(a) Except as provided in paragraphs(b)(1) through (b)(3) of this section, anyexisting point source subject to this partmay-qualify for alternative effluentlimitations to those specified in Part 420,Subparts A though L for a number of itsprocesses representing. the degree ofeffluent reduction attainable by theapplication of best practicable controltechnology currently available, bestavailable, technology economically,achievable, and best conventionaltechnology. The alternative effluentlimitations for each pollutant aredetermined for a combination of outfallsby totaling the mass limitations of eachpollutant allowed under Subparts Athough L and subtracting from each totalan appropriate net reduction amount.The permit authority shall determine anappropriate net reduction amount foreach pollutant traded based uponconsideration of additional availablecontrol measures which vrould-result innon-trival (substantial) effluentreductions and which can be achievedwithout requiring significant additionalexpenditures at any outfall(s) by whichthe discharges from any waste steam(s)in the combination for which thedischarge is projected to be better thanrequired by this regulation.

(b) In the case of Total SuspendedSolids (TSS) and Oil and Grease (O&G),the minimum net reduction amount shallbe approximately 15 percent of theamount(s) by which any waste stream(s)in the combination will exceedotherwise allowable effluent limitations.For all other traded pollutants, theminimum net reduction exceedsotherwise allowable effluent limitations.For all other traded pollutants, theminimum net reduction amount shall beapproximately 10 percent of theamount(s) by which the disclarges fromany waste stream(s) in the combinationwill exceed otherwise allowable effluentlimitations for each pollutant under thisregulation.

(1) A discharger cannot qualify foralternative effluent limitations if theapplication of such alternative effluentlimitations would result in violation ofany applicable State water qualitystandards.

(2) Each outfall from which processwastewaters are discharged must havespecific, fixed effluent limitations foreach pollutant limited by the applicableSubparts A though L.

(3) Subcategory-Specific restrictions.

(i) There shall b e no alternate effluentlimitations for cokemaking processwastewaters.

(ii) There shall be no alternatvueffluent limitations for cold formingprocess wastewaters.

3. By adding a new § 420.06 to read asfollows:

§ 420.06 Removal Credits for Phenols(4AAP).

Removal allowances pursuant to 40CFR 403.7(a)(1) may be granted forphenols (4AAP) limited in 40 CFR Part420 when used as an indicator orsurrogate pollutant.

4. The table in § 420.23 is amended byrevising the entires for cyanide, lead,and zinc as follows:

1. The authority citation for Part 403

reads as follows:

Authority: Sections 301; 304(b), (c), (e), and(g); 306(b) and (c); 307; 308 and 501, CleanWater Act (the Federal Water PollutionControl Act Amendments of 1972, asamended by the Clean Water Act of 1977).(the "Act"); 33 U.S.C. 1311; 1314(b), (c), (e),and (g); 1316(b) and (c); 1317; 1318; and 1361;86 Stat. 816, Pub. L. 92-500; 91 Stat. 1567; Pub.L. 95-217.

2. Section 403.6 (e)(1) (i) and (ii) areamended by revising the definition forFD. As revised, the definition for FD inboth paragraphs reads as follows:

§403.6 National Pretreatment Standards:Categorical Standards.

FD = the average daily flow (at least a 30-day average) from (a) boiler blowdown

46956--. , __ I m --46956


streams and non-contact cooling streams:provided, however, that where such streamscontain a significant amount of a pollutant,and the combination of such streams, prior totreatment, with an Industrial Users regulatedprocess wastestream(s) will result in asubstantial reduction of that pollutant, theControl Authority, upon application of theIndustrial User, may exercise its discretion todetermine whether such stream(s) should beclassified as dilute or unregulated. In itsapplication to the Control Authority, theIndustrial User must provide engineering,production, sampling and analysis and such

other information so that the ControlAuthority can make its determination, or (b)sanitary wastestreams (where such streamsare not regulated by a ctegorical.Pretreatment Standard) or (c) from anyprocess wastestreams which were or couldhave been entirely exempted from categoricalPretreatment Standards pursuant to paragaph8 of the NRDC v. Costle Consent Decree (12ERC 1833) for one or more of the followingreasons (see Appendix D):

(1) the pollutants of concern are notdetectable in the effluent from the IndustrialUser (paragraph (8)(a)iii));

(2) the pollutants of concern are presentonly in trace amounts and are neither causingnor likely to cause toxic effects (paragraph(8)[a](iii);

(3) the pollutants of concern are present inamounts too small to be effectively reducedby technologies known to the Administrator(paragraph (8)(a)(iii); or

(4) the wastestream contains onlypollutants which are compatible with thePOTW (paragraph (8)(b)(i)).
