I. Legal Authority

The amendments to the regulationdescribed m this notice are proposedunder the authority of sections 301, 304,307, 308, and 501 of the Clean Water Act(the Federal Water Pollution Control ActAmendments of 1972, 33 U.S.C. 1251, etseq., as amended by the Clean WaterAct of 1977, Pub. L. 92517). Thesechanges are also proposed in responseto the Settlement Agreement m NaturalResources Defense Council, Inc. v.Environmental Protection Agency, No.83-1122 (D.C. Cir.).

II. Background

A. Prior Regulation

On October 18, 1982, EPA publishedfinal effluent limitations guidelines andstandards for the petroleum refiningpoint source category. That regulationprovided final effluent limitations for"best available technology economicallyachievable" (BATJ and established finalpretreatment standards for existingsources (PSES) and for new sources(PSNS). The Agency retained itspreviously promulgated "new sourceperformance standards" (NSPS) andalso did not modify its effluentlimitations guidelines for "bestpracticable control technology currentlyavailable" (BPT). The Agency reservedcoverage of "best conventional pollutantcontrol technology" (BCT) effluentlimitations guidelines. The preamble tothe final regulation describes the historyof the rulemaking. 47 FR 46434.

.B. Challenges to the Prior Regulation

The Natural Resources DefenseCouncil, Inc. ("NRDC") filed a petitionto review the final petroleum refiningregulation. Natural Resources DefenseCouncil, Inc. v. EnvironmentalProtection Agency, No. 83-1122 (D.C,Cir.). The American Petroleum Institute("API") and seven individual oilcompanies (hereinafter referred to as"Interveners") intervened in thelitigation.

C. Settlement AgreementOn April 17,1984, EPA, NRDC, 4P

and all other interveners to the litigationentered into a comprehensiveSettlement Agreement-which resolvedall of the issues raised by the petitionerand all interveners. In the SettlementAgreement, EPA agreed to publish anotice of proposed rulemaking and tosolicit comments regarding certainmodifications to the final petroleumrefining BAT effluent limitationsguidelines. In addition, EPA agreed topropose BCT effluent limitationsguidelines for four conventionalpollutants and BPT, BAT and BCTeffluent limitations guidelines forcontaminated storm water runoff.Petitioner NRDC agreed that if EPAtakes final action pursuant to andconsistent with the SettlementAgreement that it will dismiss itslawsuit challenging the final petroleumrefining regulation.

As part of the Settlement Agreement,the parties agreed to seek a judicial stayof the regulatory provisions to bemodified. On July 24, 1984, the Courtefltered a stay of the effluent limitationsfor phenolic compounds, total chromiumand hexavalent chromium for thefollowing portions of the regulationpending the rulemaking: 40 CFR419.13(a), 419.23(a), 419.33(a), 419.43(a),and 419.53(a).

III. Proposed Amendments to thePetroleum Refining Point SourceCategory Regulation

The following are the changes to thepetroleum industry regulation that EPAis. proposing:

A. Best Available Technology EffluentLimitations Guidelines

On October 18, 1982 EPA publishedfinal effluent limitations guidelines forbest available technology economicallyachievable (BAT) and final pretreatmentstandards for existing sources (PSES)and for new sources (PSNS) for thepetroleum refining industry. 47 FR 46434,The Natural Resources Defense Council("NDRC") filed a petition to review theOctober 18, 1982 regulation in the UnitedStates Court of Appeals for the Districtof Columbia Circuit, The AmericanPetroleum Institute (API) and sevencompanies which own and operatepetroleum refineries intervened In thatproceeding. A number of issues wereraised in settlement discussions amongthe parties in the lawsuit pertaining tothe BAT effluent limitations guidelines.After extensive discussions, thepetitioner, interveners and EPA entereda Settlement Agreement, which providesfor specified revisions to the BAT

34152


effluent limitations guidelines. Thoserevisions are set forth in today's.proposal.

In October 1982 EPA promulgatedBAT effluent limitations for thefollowing pollutants: (1) Non-conventional pollutants; chemicaloxygen demand (COD], phenoliccompounds (4AAP), ammoma (as N) andsulfide; and (2) toxic pollutants: totalchromin and hexavalent chromium.The model technology for theseregulations was flow equalization, initialoil and solids removal, advanced oil andsolids removal, biological treatment andfiltration or other final "polishing steps."

The Agency is now proposing toamend the BAT effluent limitationsguidelines for total chromium,hexavalent chromium and phenoliccompounds (4AAPJ. EPA is proposing toadd flow reduction to the modeltreatment technology for the BATeffluent limitations guidelines and tobase the effluent limitations for each ofthese three pollutants on a more recentdata base, rather than the one it reliedupon in the October 18,1982 BA'Ipromulgation. That rulemaking utilizedthe same data base used by the Agencywhen it established best practicablecontrol technology currently available(BPT) effluent limitation guidelines forthe petroleum refining point sourcecategory. BPT level of control for thisindustry was promulgated on May 9,1974 (39 ER 16560) and subsequentlyamended on May 20,1975 (40 FR 21939).The'BAT effluent limitation guidelinesfor other pollutants would remainunchanged.

The BAT effluent limitationsguidelines for total chromium beingproposed today-are based upon therevised 1979 flow model developed bythe Agency to predict refinery flows,rather than the BPT 1974 flow modelused in the October 1962-BATpromulgation. The effluent limitationsfor total chromium proposed today werederived by applying this updated flowmodel to concentrations for totalchromium observed from plant samplingin 1976-1977

BAT effluent limitations guidelines forhexavalent chromium and phenoliccompounds being proposed today werederived using the 1982 DevelopmentDocument concentrations and therevised 1979 flow model to moreaccurately represent effluent reductionsfor these pollutants which the industrywas generally achieving in 1979 or couldtechnologically was generally achievingin 1979 or could technologically achieveby the final BAT compliance date. BATfor hexavalent chromium beingproposed today is based upon Option 7(discharge flow reduction of 37.5 percent

from the revised 1979 model flow). BATfor phenolic compounds (4AAP) beingproposed today is based upon option 8(a reduction of 20 percent from therevised 1979 model flow).

Under today's proposal the BATeffluent limitations guidelines for eachof these there pollutants would besubstantially more stringent than the

.-BAT effluent limitations guidelinespromulgated in 1982. The total allowabledischarge of total chromium to thenation's navigable waters would bereduced by approximately 2C5,000pounds per year, a 667 annual reductionbeyond discharge levels allowableunder the existing BAT effluentlimitations guidelines; the totalallowable discharge of hexavalentchromium would be reduced byapproximately 19,300 pounds per year, a56% annual reduction beyond dischargelevels allowable under existing BAT; thetotal allowable discharge of phenoliccompounds (4AAP], would be reducedby approximately 75.000 pounds peryear, a 43% annual reduction beyonddischarge levels allowable underexisting BAT. These reductions arebased on data in the Agency's refinedBAT model. The refined flow model isincluded in the record for flusrulemaking proposal in a report entitled"Petroleum Refining Industry,Refinements to 1979 Proposed FlowModel."

EPA believes that approximately onehalf of refineries which directlydischarge pollutants to navigable watersalready are complying with the effluentlimitations being proposed today.Further, EPA believes that these effluentlimitations are economically achievablefor the industry.

In the preamble to the October 18,1982 promulgated regulations for thisindustry, EPA estimated that capitalcosts of $112 million and $37 million(1979 dollars) in annualized costs wouldbe required in order for petroleumrefiners to comply with option 7, one ofthe BAT control treatment optionsconsidered by the Agency (47 FR 46438).Likewise, EPA estimated that capitalcosts of $77 million and annualizedcosts of $25 million (1979) dollars wouldbe required in order for petroleumrefiners to comply with option 8, anotherof the BAT control treatment optionsconsidered by the Agency (47 FR 46438).

The revised limitations beingproposed today for phenolic compounds,hexavalent chromium and totalchromium are not based on either option7 or option 8 alone. The effluentlimitations for phenolic compounds arebased upon option 8. The effluentlimitations for hexavalent chromium arebased upon option 7 The effluent

limitations for total chromium, whilesomewhat more stringent than the BPTeffluent limitations for total chromium,are less stringent than those based uponoption 8.

The Agency has reevaluated the costsof compliance for today's proposedchanges to the BAT effluent limitationsand estimates that the total industrycosts of compliance would not exceedthose previously calculated for option 8.EPA estimates that no more than 61petroleum refineries will have to incuragregate capital costs no greater than$77 million and annualized costs nogreater than $25 million (1979 dollars).These costs translate to an averageincrease of no greater than one half centper gallon of refinery product Norefinery closures are anticipated by theAgency. Refinery capacity andconsumption would remain unaffected.Given these factors, the Agency believesthat its earlier heavy reliance on costsas the basis for rejecting more stringenteffluent controls in this industry wasinappropriate, and that the effluentlimitations guidelines for totalchromium, bexavalent chromium andphenolic compounds (4AAP) being -proposed today, rather than the effluentlimitations guidelines promulgated in1982. are appropriate for tlus industry asthe BAT level of control. The revisedproposed BAT numerical limitations arecontained in the proposed regulation.

B. Best Conventionol PolutantTechnology Effluent Lmr'tationsGidelines

As part of the Settlement AgreementEPA agreed to propose bestconventional pollutant controltechnology ("BCT") effluent limitationsguidelines for the petroleum refiningindustry. The 1977 Amendments to theClean Water Act ("CWA') addedsection 301(b)(2)(E) of the Actestablishing BCT for discharge ofconventional pollutants from existingindustrial point sources. Conventionalpollutants are those defined in Section304(a)(4) [biochemical oxygendemanding pollutants (BOD ), totalsuspended solids (TSS). fecal coliformand pH]. and any additional pollutantsdermed by the Administrator as"conventiona' The Administratordesignated oil and grease as aconventional pollutant on July 30,1979,44 FR 44501.BCT is not an additional limitation but

replaces BAT for the control ofconventional pollutants. In addition toother factors specified in section304(b)[4)(B) the Act requires the BCTlimitations be assessed in light of a twopart "cost reasonableness" test.

34153


American Paper Institute v. EPA, 660F2d 954 (4th Cir. 1981). The first testcompares the cost for private industry toreduce its conventional pollutants withthe costs to publicly owned treatmentworks for similar levels of reduction intheir discharge of these pollutants. Thesecond test examines the cost-ceffectiveness of additional industrialtreatment beyond best practicablecontrol technology currently available(BPT). EPA must find that limitations are"reasonable" under both tests beforeestablishing them as BCT. In no casemay BCT be less stringent than BPT.

EPA published a proposed BCTmethodology on October 29, 1982. (47 FR49176). This proposed BCT methodologyexplains the details of the two part cost-reasonableness test, i.e., the "POTWtest" and the "industry cost test"Today's proposed BCT effluentlimitations guidelines for the petroleumrefining industry are based on theproposed BCT methodology. EPA isproposing that BCT be set equal to BPTfor the petroleum refinung industry.

EPA considered two levels oftechnology for incremental controlbeyond BPT of total suspended solids(TSS) and oil and grease. Thesetechnology levels are recycle/reuse andrecycle/reuse followed by granularmedia filtration. These technologies arealready m use at certain sites in thepetroleum refining industry. Thesetechnologies were selected as candidateBCT technologies because the Agencybelieves they represent the first levels ofcontrol beyond BPT which could effectreductions m conventional pollutantloadings in tlus industry. Filtration alonewas not selected as a candidate BCTtechnology because it is one of theexisting BPT treatment technologies.However, the Agency decided toconsider the combination of recycle/reuse plus filtration as a candidate BCTtechnology. This is because thedecreased hydraulic loading resultingfrom recycle/reuse results in the needfor smaller and less costly filtrationequipment than that included in the BPTtreatment model. The BCT cost test wasthen performed on the combination ofrecycle/reuse and filtration as a double-check on the effects of the less costlyfiltration step.

In order to deternune whether thesecandidate technologies are "cost-reasonable", EPA developed one modelplant representative of a typical plant meach of the five BPT subcategories. Thefive BPT subcategories are:A-ToppingB-CrackingC-PetrochemicalD-Lube

E-IntegratedThen EPA calculated the incremental(beyond BPT) conventional pollutantremovals and the incremental costsassociated with these technologies foreach model plant. Based on thisinformation, cost-per-pound ratios werecalculated for each of the five BPTsubcategories.

EPA evaluated reductions in totalsuspended solids (TSS), biochemicaloxygen demand (BOD,5), and oil andgrease for each of these technologylevels. However, oil and grease was notconsidered for the BCT calculations forrecycle/reuse for this industry.Additionally, BOD5 was not consideredfor the BCT calculations for filtration forthis industry. This is in accordance withthe proposed BCT methodology in orderto avoid "double counting" of theamount of pollutants removed by acandidate BCT technology.

The recycle/reuse technology optionidentified for BCT was evaluated in therange of from 20 to 40 percent reductionm discharge flow. The cost per poundranges from $41.00 to $0.77 (1977 dollars)in the first part of the proposed BCT costreasonableness test (the "POTW test").Accordingly, the Agency found that theaddition of recycle/reuse technologyfails the first part of the proposed BCTcost reasonableness test in all fivesubcategories ($0.30 per pound in 1977dollars).

The Agency also found that theaddition of recycle/reuse plus filtrationfails the first part of the proposed BT.cost reasonableness test m all fivesubcategories. The recycle/reuse portionof this option was evaluated in the rangeof from 20 to 40 percent reduction indischarge flow. The cost per pound (1977dollars) ranges from $21.00 to $0.58,compared to the benchmark of $0.30 perpound (1977 dollars).

Therefore, the Agency is proposingthat BCT be set equal to BPT for the fivesubcategories in this industry.

A more complete discussion of theselection of the candidate BCTtechnologies, the details of the first partof the proposed BCT costreasonablenesss test ("POTW test"),and the basis for decision on thisproposal are contained in theadnumstrative record of this rulemaking.C. Effluent Limitations Guidelines forContaminated Storm Water Runoff

In the October 18,1982 rulemaking theAgency withdrew storm water effluentlimitations guidelines for BPT, BAT andNSPS, because they were remanded bythe U.S. Court of Appeals m AmericanPetroleum Institute v. EPA, 540 F.2d 1023(10th Cir. 1976).

Since that remand there has beensome confusion on the part of permitwriters and others as to whether stormwater runoff ("runoff") effluentlimitations should be contained inpermits. There are two kinds of suchrunoff, i.e., contaminated anduncontaminated. The purpose of thisrulemaking is to establish BPT, BCT andBAT effluent limitations guidelines forcontaminated storm water runoff, Theseproposed contaminated runoff effluentlimitations would be included inpetroleum refinery permits In addition toprocess wastewater effluent limitations.NSPS for contaminated runoff is beingreserved for future rulemaking.

In today's proposal EPA is definingcontaminated runoff, for purposes ofthese regulations only, ta be runoffwhich comes into contact with any rawmaterial, inteFnediate product, finishedproduct, by-product or waste productlocated on petroleum refinery property.Any other storm water runoff at arefinery is considered uncontaminated.In today's proposal, EPA also isproposing to amend the definition of theterm "runoff" currently found In 40,.CFR419.11(b) to clearify that It means theflow of storm water resulting fromprecipitation coming into contact withpetroleum refinery property.Contaminated runoff constitutes anadditional source of pollution whichmust be managed during periods ofprecipitation along with processwastewater from refinery operations,The regulations being proposed todaydo not establish numerical effluentlimitations for uncontaminated runoff.Effluent limitations, including but notlimited to allocations, foruncontaminated runoff may beestablished by the permit writer basedon his/her best professional Judgment,

The Agency believes that the bestpracticable control technology currentlyavailable, the best conventionalpollutant control technology and thebest available technology economicallyachievable for treatment ofcontaminated runoff are the same as thetechnologies identified for treatment ofprocess wastewater. The Agency hasnot identified any feasible technologiescapable of achieving pollutantreductions for contaminated runoff fromrefineries to any greater degree thanthose which are achievable by theprocess wastewater treatment facility.

The Agency believes that theconventional pollutant oil and greaseand the nonconventional pollutantparameter total organic carbon (TOC)are appropriate measures to determinewhether pollutant loadings incontaminated runoff would be

34154

Federal Regster / Vol. 49, No. 168 / Tuesday, August 28, 1984 / Proposed Rules

measurably reduced by the modeltreatment technologies used to developthese proposed regulations. Undertoday's proposal for BPT, wastewaterconsisting solely of contaminated runoffmay be discharged directly withouttreatment if it does not exceed 15 mg/loil and grease and 110 mg/l TOC, basedupon an analysis of any single grab orcomposite sample. Under today'sproposal for BCT, wastewater consistingsolely of contaminated runoff may bedischarged directly without treatment, ifit does not exceed 15 mg/l oil and greaseand under today's proposal for BAT,wastewater consisting solely ofcontaminated runoff may be dischargeddirectly without treatment if it does notexceed 110 mg/l TOC. If contaminatedrunoff (whether or not it exceeds 15 mg/I oil and grease or 110 mg/l TO] iscommingled or treated with processwastewater, or if wastewater consistingsolely of contaminated runoff whichexceeds 15 mg/1 oil and grease or 110mg/I TOC is not commingled or treatedwith any other type of wastewater, thensuch runoff would be subject to thealternative BPT/BCT/BAT effluentlimitations guidelines for contaminatedrunoff being proposed today, asappropriate. These oil and grease andTOC numerical effluent limitations arebased on the concentrations expectedfrom the properly designed and operatedmodel treatment facilities.

The effluent limitations guidelines intoday's BPT proposal for contaminatedrunoff are based on the sameconcentrations and variability factorsused to develop the Agency's existingBPT process wastewater effluentlimitations guidelines.

Today's BAT proposal forcontaminated runoff is based upon thesame concentrations and variabilityfactors used to develop the Agency'sexisting BAT process wastewatereffluent limitations guidelines, exceptthose for total chromium, wich arebased upon the same concentrationsand variability factors used for today'sproposed BAT effluent limitationsgwdelines for process wastewater.

Today's proposed BAT effluentguidelines for phenolic compounds(4AAP) for contaminated runoff arebased on-the same concentrations usedfor today's existing BAT effluentlimitations guidelines for processwastewater and the same variabilityfactors used for the Agency's existingBAT effluent limitations guidelines. EPAhas determined that this approach isappropriate in this proposal because ofthe specifics of each data base availableto the Agency. If EPA used thevariability factors from today's

proposed BAT effluent limitationsguidelines, less stringent BATcontaminated runoff numerical effluentlimitations for phenolic compounds(4AAP) would be derived than undertoday's proposed BPT contaminatedrunoff numerical effluent limitations forphenolic compounds (4AAP). The morestringent effluent limitations clearly areachievable and as a matter of law BATcannot be less stringent than BPT.

Today's BCT proposal forcontaminated runoff is based on thesame concentrations and variabilityfactors used for today's proposed ECTprocess wastewater effluent limitationsguidelines.

The Agency believes that the costsattributable to today's proposal will beminimal, while providing for reductionsin refinery pollutant discharges. This isbecause the Agency believes theindustry as a whole already is (a)treating contaminated runoff withprocess wastewater or (b) is dischargingcontaminated runoff below today'sproposed threshold for treatment. Thisproposal does not cover contaminatedrunoff which is commingled with non-process wastewater streams. EPAbelieves that such instances areinfrequent, and accordingly, they are leftto the permit writer's discretion.

Unlike the effluent limitationsguidelines for process wastewater forthis industry which are mass-based.today's proposed effluent limitationsguidelines for contaminated runoff areconcentration-based. This is becausestorm water volumes are not related toany measurement of refinery production.However, under today's proposal permiteffluent limitations for contaminatedrunoff are to be established on a massbasis. The mass-based effluentlimitations for each regulated pollutantfor contaminated runoff in a petroleumrefining permit are the product of (1) therespective effluent guidelineconcentration for that pollutant; and (2)the measured or calculatedcontaminated runoff volume.

Under today's proposal permit writersare given flexibility in determiningrefinery storm water volumes on a caseby case basis. The following factors areamong those appropriate for permitwriters to consider in determining whatcontaminated runoff volume to use incalculating mass-based effluentlimitations for refinery permits: (a)Measured difference between dryweather and wet weather dischargeflow from the treatment facility wherecontaminated runoff is the only runoffpresent in the treatment facility; and (b)volume of contamnnated runoff watercalculated from the product of (1)

measurement of land area whereprecipitation would becomecontaminated, and (2) an historicalmeasure of precipitation for theparticular refinery location.

Once the mass based effluentlimitation is derived, it may beincorporated into a refinery permit inone of three ways. The proper choicedepends on site-specific factors, such aslocal rainfall patterns and the design ofrunoff holding facilities.

The first method is a continuousallocation. This presents the problem ofproviding an allocation when no runoffis present and is appropriate only whereprecipitation patterns are relativelyconstant through the year or whenholding facilities are used to bleedrunoff into the treatment facility overmost or all of the year. The secondmethod is a variable allocation based onmeasurement or calculation of actualcontaminated runoff volume. While thisis the most ideal method, it may presentcompliance measurement andenforcement complexities. The thirdmethod is dual wet weather/dryweather limitations triggeredby eithertime of year, precipitation events, oractual contaminated runoff volume. Themethod of determining contaminatedrunoff volume used to calculate theeffluent limitations will vary dependingon the method used and the design ofany runoff holding facilities. Therefore,it is left to the permit writer to select anappropriate method under today'sproposal.

These proposed regulations do notaddress uncontaminated runoff which isdischarged through the processwastewater treatment facility. This isbecause the Agency believes thatintroducing uncontaminated runoff tothe process wastewater treatmentsystem may result in the discharge of anincreased mass of pollutants to theenvironment compared to the mass ofpollutants.discharged if nouncontaminated runoffwere present inthe process wastewater treatmentsystem. Therefore, the Agency does notwant to encourage this practice on anational basis.

In the case of BPT, the effluentlimitations guidelines being proposedtoday are for the following pollutants:(1) conventional pollutants totalsuspended solids (TSS), oil and grease,five-day biochemical oxygen demand(BOD ) and pH; (2] nonconventionalpollutants phenolic compounds (4AAP),chemical oxygen demand (COD) andtotal organic carbon (TOG]; and (3) toxicpollutants total chromium andhexavalent chromium. In the case ofBAT, the effluent limitations guidelines

34155


being proposed today are for: (1)Nonconventional pollutants phenoliccompounds (4AAP), chemical oxygendemand (COD) and total organic carbon(TOC); and (2) toxic pollutants totalchromium and hexavalent chromium. Inthe case of BCT, the effluent limitationsguidelines .being proposed today are forthe conventional pollutants TSS, oil andgrease, BOD5 and pH. In the case ofCOD, there may be instances whereextremely high chloride levels (greaterthan 1,000 mg/l) will interfere with theCOD analytical method. In this event,the Agency believes that TOC is anacceptable substitute parameter forCOD. A TOC limitation shall be basedupon effluent data from-the particularrefinery which correlates TOC to BODs.Where adequate correlation data are notavailable, the permitting authority mayestablish a TOC limitation on a ratio of2.2 to 1 to the applicable BPT/BCTeffluent limitations for BODs. This ratiois based upon effluent data analyzed bythe Agency.

No effluent'limitations guidelines forcontaminated runoff are being proposed,for the nonconventional pollutantsammonia (as N) and sulfide regulatedunder existing BPT and BAT levels ofcontrol. 1

V Solicitation of CommentsEPA invites public participation in

this 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.VI. Executive Order 12291

Under Executive Order 12291, EPAmust judge whether a regulation is

"major" and therefore subject to therequirement of a Regulatory ImpactAnalysis. This proposed regulation isnot major because it does not fall withinthe criteria for major regulationsestablished in Executive Order 12291VII. 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. The Agencydoes not believe that today's proposedamendments will have a significantimpact on any segment of the petroleumrefining industry, large or small. TheAgency is not, therefore, preparing aformal analysis for this regulation.

VIII. OMB ReviewThis regulation was submitted to the

Office of Management and Budget forreview as required by Executive Order12291.

§419.54 Effluent lImitations guidelinesrepresenting the degree of effluentreduction attainable by the application ofthe best conventional pollutant controltechnology (BCT): I

(a) Any existing point source subjectto this subpart must achieve thefollowing effluent limitationsrepresenting the degree of effluentreduction attainable by the applicationof the best conventional pollutant,control technology (BCT):

(3) See the comprehensive example inSubpart D, § 419.42(b)(3).

(c] The provisions of § 419.14(c) applyto discharges of process wastewaterpollutants attributable to ballast waterby a point source subject to theprovisions of this subpart.

(d) The quantity and quality ofpollutants or pollutant propertiescontrolled by this paragraph.attributable to once-through coolingwater, are excluded from the dischargeallowed by paragraph (b) of this section.

(e) Effluent Limitations forContaminated Runoff. The followingeffluent limitations constitute thequantity and quality of pollutants orpollutant properties controlled by this

paragraph and attributable tocontaminated runoff which may bedischarged after the application of thebest conventional pollutant controltechnology by a point source subject tothis subpart.

(1) If wastewater consists solely ofcontaminated runoff and is notcommingled or treated with processwastewater. it may be discharged if itdoes not exceed 15 mg/l oil and greasebased upon an analysis of any singlegrab or composite sample.

(2) If contaminated runoff iscommingled or treated with processwastewater, or if wastewater consistingsolely of contaminated runoff whichexceeds 15 mg/l oil and grease is notcommingled or treated with any othertype of wastewater, the quantity ofpollutants discharged shall not exceedthe quantity determined by multiplyingthe flow of contaminated runoff asdetermined by the permit writer timesthe concentrations listed in thefollowing table:
