Proposed Effluent Limitations Guidelinesfor Existing Sources and Standards ofPerformance and Pretreatment Stand-ardsNotice is hereby given that effluent

limitations and guidelines for existingsources and standards of performanceand pretreatment standards for newsources set forth in tentative form be-low are proposed by the EnvironmentalProtection -Agency (EPA). On Janu-ary 22, 1974, EPA promulgated a regu-lation adding Part 426 to title 40 of theCode of Federal Regulations (39 FR2564). That regulation with subsequentamendments established effluent limita-tions and guidelines for existing sourcesand standards of performance and pre-treatment standards for new sources forthe Insulation fiberglass subcategory ofthe glass manufacturmg point sourcecategory. The regulation proposed belowwill amend 40 CFR, Part 426-gla s man-ufacturing point source category by add-ing thereto the glass container manu-facturing subcategory (Subpart H), themachine pressed and blown glass manu-facturing subeategory (Subpart I), theglass tubing manufacturing subcategory(Subpart J), the television picture tubeenvelope manufacturing subcategory(Subpart X), the incandescent lamp en-velope manufacturing subcategory (Sub-part L), and the hand pressed and blownglass manufacturing subcategory (Sub-part M), pursuant to sections 301, 304 (b)and (c), 306(b) and 307(c) of the Fed-eral Water Pollution Control Act, asamended (33 U.S.C. 1251, 1311, 1314 (b)and (c), 1316(b) and 1317(c); 86 Stat.816 et seq.; Pub. L. 92-500) (the Act).

(a) Legal authority.-(1) Existingpoint sources. Section 301(b) of the Actrequires the achievement by not laterthan July 1, 1977, of effluent limitationsfor point sources, other than publiclyowned treatment works, which requirethe application of the best practicablecontrol technology currently available asdefined by the Administrator pursuantto section 304(b) of the Act. Section301(b) also requires the achievement bynot later than July 1, 1983, of effluentlimitations for point sources, other thanpublicly owned treatment works, whichrequire the application of best availabletechnology economically achievablewhich will result in reasonable furtherprogress toward the national goal ofeliminating the discharge of all pollut-ants, as determined in accordance withregulations issued by the Administrator-pursuant to section 304(b) of the Act.

Section 304(b) of the Act requires theAdministrator to publish regulationsproviding guidelines for effldient limita-tions setting forth the degree of effluentreduction attainable through the appli-

cation of the best practicable controltechnology currently available-and thedegree- of effluent reduction attainablethrough the application of the best con-trol measures and practices achievableincluding treatment techniques, processand procedural innovations, operatingmethods and other alternatives. Theregulation proposed herein sets forth ef-fluent limitations and guidelines, pursu-ant to sections 301 and 304(b) of the Act,for the glass container manufacturingsubcategory (Subpart H), the machinepressed and blown glass manufacturingsubcategory (Subpart I), the glass tubingmanufacturing subcategory (Subpart J),the television picture tube envelopemanufacturing subcategory (Subpart K),the incandescent lamp envelope manu-facturing subcategory (Subpart L), andthe hand pressed and blown glass manu-facturing subcategory (Subpart 11), ofthe glass manufacturing point sourcecategory.

(2) New sources. Section 306 of the Actrequires the achievement by new sourcesof a Federal standard of performanceproviding for the control of the dischargeof pollutants which reflects the greatestdegree of effluent reduction which theAdministrator determines to be achiev-able through application of the bestavailable demonstrated control technol-ogy, processes, operating methods, orother alternatives, including, where prac-ticabld a standard permitting no dis-charge of pollutants.

Section 306(b) (1) (B) of the Act re-quires the Administrator to propose reg-ulations establishing Federal standardsof performance for categories of newsources included in a list published pur-suant to section 306(b) (1) (A) of theAct. The Administrator published in theFEDERAL REGISTER of January 16, 1973,(38 FR 1624) a list of 27 source cate-gories, including the glass and asbestosmanufacturing category. The regulationsproposed herein set forth the standardsof performancQ applicable to newsources for the glass container manufac-turing Subeategory (Subpart H), the ma-chine pressed and blown glass manufac-turing subcategory (Subpart I), the glasstubing manufacturing subeategory (Sub-part J), the television picture tube envel-ope manufacturing subcategory (Sub-K), the incandescent lamp envelopemanufacturing subcategory (Subpart L),and the hand'pressed and blown glassmanufacturing subcategory (Subpart M),of the glass manufacturing point sourcecategory.

Section 307(c) of the Act requires theAdministrator to promulgate pretreat-ment standards for new sources at thesame time that standards of perform-ance for new sources are promulgatedpursuant to section 306. Sections 426.86,426.96, 426.106, 426.116, 426.126, and426.136, proposed below, provide pre-treatment standards for new sourceswithin the glass container manufactur-ing subcategory (Subpart H), the ma-chine pressed and blown glass manu-facturing subeategory (Subpart I), theglass tubing manufacturing subcategory

(Subpart J), the television picture tubeenvelope manufacturing subcategory(Subpart K), the Incandescent lampenvelope manufacturing subcategory(Subpart L), and the hand pressed andblown glass manufacturing subcategory(Subpart M), of the glass manufacturingpoint source category.

Section 304(c) of the Act requires theAdministrator to Issue to the States andappropriate water pollution controlagencies information on the processes,procedures or operating methods whichresult in the elimination or reduction ofthe discharge of pollutants to implementstandards of performance under Section306 of the Act. The report or "Develop-ment Document" referred to below pro-vides, pursuant to Section 304(c) of theAct, information on such processes, pro-cedures or operating methods.I (b) Summary and basis of proposedeffluent limitations guidelines for existingsources and standards of performanceand pretreatment standards for newsources:

(1) General methodology, The ef-fluent limitations, guidelines and stand-ards of performance proposed hereinwere developed in the following manner.The point source category was firststudied for the purpose of determiningwhether separate limitations and stand-ards are appropriate for different seg-ments within the category. This anal-ysis included a determination of whetherdifferences in raw material used, productproduced, manufacturing process em-ployed, age, size, waste water con-stituents and other factors require de-velopment of separate limitations andstandards for different segments of thepoint source category. The raw wastecharacteristics for each such segmentwere then Identified. This included ananalysis of the source, flow and volumeof water used In the process employed,the sources of waste and waste waters inthe operation, and the constituents of allwaste water. The constituents of thewaste waters which should be subject toeffluent limitations and standards ofperformance were Identified.

The control and treatment technolo-gies eLxsting within each segment, wereidentified. This Included an identifica-tion of each distinct control and treat-ment technology, including both in-plant and end-of-process technologies,which are existent or capable of beingdesigned for each segment. It also in-cluded an Identification of, In terms ofthe amount of constituents and thechemical, physical, and biologicalcharacteristics of pollutants, the effluentlevel resulting from the application ofeach of the technologies. The problems,limitations, and reliability of each treat-ment and control technology were alsoIdentified. In addUtion, the non-waterquality environmental impact, such asthe'effects of the application of suchtechnologies upon other pollution prob-lems, including air, solid waste, noise,and radiation were Identified. The energyrequirements of each control and treat-ment technology were determined as

PROPOSED RULES

well as the cost of the application of suchtechnologies-

The information, as outlined above,was then evaluated in order to deter-mine what levels of technology-consti-tute the "best practicable controltechnology currently available". "bestavailable technology economicallyachievable", and the "best availabledemonstrated control technology, proc-esses, operating methods, or other alter-natives". In identifying such technolo-gies, various factors were considered.These included the total cost of appli-cation of technology in relation to theeffluent reduction benefits to be achievedfrom such application, the age of equip-ment and facilities involved, the processemployed, the engineering aspects of theapplication of various types of controltechniques, process changes, non-waterquality environmental impact (includingenergy requirements) and other factors.

The data upon which the above analy-sis was performed included EPA permitapplications, EPA sampling and inspec-tions, consultant reports, and industrysubmissions.

The pretreatment standards proposedherein are intended to be complementaryto the pretreatjnent standards proposedfor existing sources under 40 CFR Part128. The basis for such standards is setforth in the FEDEALm RErssR of July 19,1973, 38 FR 19236. The provisions ofPart 128 are equally applicable to sourceswhich would constitute "new sources",under section 306 if they were to dis-charge pollutants directly to navigablewaters, except for § 128.133. That sectionprovides a pretreatment standard for"incompatible pollutants" which requiresapplication of the "best practicable con-trol technology currently available", sub-ject to an adjustment for amounts ofpollutants removed by the publicly ownedtreatment works. Since the pretreatmentstandards proposed herein apply to newsources, §§ 426.86,426.96,426.106,426.116426.126, and 426.136 below amend§ 128.133 to specify the application of thestandard of performance for new sourcesrather than the "best practicable" stand-ard applicable to existing sources undersections 301 and 304(b) of the Act

(2) Summary of conclusions with re-spect to the glass container manufac-turing subcategory (Subpart H), themachine pressed and blown glass manu-facturing subcategory (Subpart D, theglass tubing manufacturing subcategory(Subpart J), the television picture tubeenvelope manufacturing subcategory(Subpart 1K), the incandescent lamp en-velope manufacturing subcategory (Sub-

-part L). and the hand pressed and blownglass manufacturing subcategory (Sub-part M), of the pressed and blown glasssegment of the glass manufacturingpoint source category,(i) Categorization. For the purpose

of establishing effluent limitations guide-lines and standards of performance, thepressed and blown glass segment of theglass manufacturing category has beendividedinto six categories:

(1) Subpart H. Glass Container Man-ufacturing Subcategory: This subcate-

gory Includes those plants which meltraw materials at their facility andmechanically process the resultant Classinto glass containers.

(2) Subpart 1. Machine Presed andBlown Glass Manufacturing Subate-gory: This subeategory includes thoseplants which melt raw materials at theirfacility and mechanically process the re-sultant glass into pressed or blown classproducts.

(3) Subpart J. Glass Tubing Manu-facturing Subcategory: This subcategoryincludes those plants which melt rawmaterials at their facility and produceglass tubing as the final product.

(4) Subpart K. Television PictureTiibe Envelope Manufacturing Subcate-gory: This subeategory includes thoseplants which melt raw materials at theirfacility and produce from the resultantglass, television picture tube envelopes asthe final product.

(5) Subpart L. Incandescent LampEnvelope Manufacturing. Subcategory:This subcategory includes those plantswhich melt raw materials at their facil-ity and produce incandescent lamp en-velopes. This subeategory also includesthose plants which frost the envelopes byetching with hydrofluoric acid (HF).

(6) Subpart L. Hand Pressed andBlown Glass Manufacturing Subcate-gory: This subcategory includes thoseplants which melt glass at their facilityand hand process the resultant glass intopressed or blown glass products.

Factors such as raw materials used,age and size of production facilities,principal products and production proc-esses, waste water characteristics, andapplicable treatment methods substanti-ate and verify this subcategorlzation.

(1) Waste charactcristics. The kmownsignificant pollutant properties or con-stituents of waste waters resulting fromthe manufacture of pressed and blownglass include suspended solids, oil, andpH. In addition to these parameters,fluoride may be present to varying de-grees in waste waters associated withthe manufacture of- tdevision picturetube envelopes, incandescent lamp en-velopes, and hand pressed and blownglassware. Lead is slnificant in wastewaters resulting from the production oftelevision picture tube envelopes andcertain hand pressed or blown glassware.Ammbnia is present in sigmilfleant quan-tities in waste waters resulting from thefrosting of incandescent lamp envelopes.Other less significant parameters asso-,elated with waste water resulting fromthe manufacture of preed and blownglass are chemical oxygen demand, dis-solved solids, and heat.

(iii) Origin of waste water PoUutants.Water is used during the manufactureof pressed and blown class for non-con-tat cooling, quenching of cullet, contactcooling of metallic forming or cuttingdevices, batch wetting, abrasive polish-ing, edge grinding, washing, and assortedother uses. A discussion of water usageand the source of pollutant dischargesfollows:

(1) Glass container manufacturingsubcategory. Proes water is used for

cullet quenching, batch wetting, contactcooling of shears, and non-contact cool-ing of batch feeders, melting furnaces,formIng machines, and other auxiliaryequipment. The principal pollutants as-sroated With this subcategory are oil,present In the shear spray or due to lea.-Ing lubricantz; suspended solids, presntin the cullet quenching dischage stream;and pHL

(3) Glass tubing manufacturing sub-category. Prowes water is used for culletquenching and for non-contact coolingof furnace walls and mandrel transrnis-sion. The principal pollutants as-o-ciated with this subcate ory are oil, re-sulting from lubrication leaks; sus-pended solids, present In the culletquench stream; andpH.

(4) Television picture tube envelopemanufacturing subcategory. Water isused for cullet, quenching, batch wetting,contact cooling of she=, non-contaztcooling (of batch feaders, furnaces,presses and miliary equipment), abra-sive polishing, edge grinding, and acidpolishing. The principal pollutants asso-elated With this subcategory are fluoride,contributed by fume scrubbers and acidpolishing rinse waters; lead, present inboth the abrasive and acid polishing dis-charge streanm; susp ded solids, pres-ant in the cullet quench, abrasive polish-

ing, and edge grinding dischargestreara; oil. contributed by s spraydri-ppge, lubrication leaks, and funnelrinse w ater; and PH.

(iv) Treatment and control tech-nology. Waste water treatment and con-trol technologies have been studied foreach subcategory of the industry to de-termine what is (a) the best practicablecontrol technology currently available,(b) .the best available technology eco-nomically achievable, and (c) the bestavailable demonstrated control tech-nology, processes, operating methods orother alternatives. Such technologies ascoagulation, sedimentation, oil separa-tion, lime precipitation, ion-exchange,ammonia stripping, and filtration havebeen considered and recommended asproven methods of control and treatmentof waste waters from the pressed andblown glass segment of the glass manu-facturing category. Many of these tech-nologies are currently practiced withinthe industry; all are readily transferabledue to their wide practice within otherindustrial categories or within the fieldof water treatment.

The following is a discussion of" thecontrol and treatment technologiesrecommended for each subcategory asbest practicable control technology eco-nomically achievable.

(1) Recommended control and treat-ment-glass container manufacturingsubcategory. Both in-plant- techniquesand end-of-pipe methods have been em-ployed by plants of this subcategory to re-duce pollutant discharge. Best practica-ble control technology currently availablewould require that a typical plant using2920 I/metric ton (700 gal/ton) of com-bined process and non-contact coolingwater achieve effluent.levels 9f 24 mg/1for suspended solids and 10 mg/1 for oil.A plant with segregation of process andnoncontact cooling water would be re-quired to attain effluent concentrationlevels of approximately double the afore-mentioned with regard to the processwater stream as this stream accountsfor approximately forty-seven percent ofthe combined flow. These levels are con-sidered to be typical of current operationand are presently achieved by 70 percentof the 40 plants for which effluent data isavailable. These effluent levels are readilyachievable by all plants within this sub-category throfigh normal maintenanceand clean-up operations within the plantand represent the raw waste loadings ex-pected from a glass container plant.Some plants may need to improve house-keeping to achieve the recommendedeffluent levels, while others may elect toprovide end-of-pipe treatment in the'form of some type of sedimentation sys-tem with oil removal capabilities. It isfelt however, that in-plant techniqueswill be a more effective and a consider-ably less expensive means of achievingthe recommended effluent limitations andbest practicable control technology cur-rently available is based on thiscontention.

Best available technology economicallyachievable recommends that the culletquench waste water stream be segregatedfrom the non-contact cooling waterstream, that the cullet quench stream berecirculated through a gravity separator

with treatment of the blowdown by dis-solved air flotation, and that the effluentfrom the dissolved air flotation system befiltered through diatomaceous earth.This will further reduce oil and sus-pended solids in the discharge stream toless than 5 mg/1 and will reduce the con-tact water discharge flow from 1540 1/metric ton (370 gal/ton) to 77 I/metricton- (18.5 gal/ton).

(2) Recommended control and treat-ment-machine pressed and blown glassmanufacturing subcategory. The in-plantcontrol and end-of-pipe treatment meth-ods employed in the machine pressedand blown glas manufacturing subcate-gory are those used in the glass con-tainer manufacturing subcategory. Bestpracticable control technology currentlyavailable would require that a typicalplant using 5630 1/metric ton (1350 gal/ton) of combined process and non-contact cooling water achieve effluentlevels of 25 mg/I for suspended solids and10 mg/1 for oil. A plant with segregationof process and non-contact cooling waterwould be required to attain effluent con-centration levels of approximately doublethe aforementioned with regard- to theprocess water stream as this stream ac-counts for approximately forty-blght per-cent of the combined flow. These effluentlevels are readily achievable by all plantswithin the subcategory with a minimumof in-plant controls or end-of-pipetreatment.

Best available technology economicallyachievable involves the segregation ofcullet quench from noncontact coolingwaters, the recirculation of the culletquench stream through a gravity sepa-rator with treatment of the blowdownby dissolved air flotation, and the diato-maceous earth filtration of the effluentfrom the dissolved air flotation system.This will .further. reduce oil and sus-pended solids in the discharge stream toless than 5 mg/I and will reduce the con-tact water discharge flow from 2920 1/metric ton (700 gal/ton) to 370 I/metricton (88 gal/ton).

(3) Recommendled control and treat-ment--glass tubing manufacturing sub-category. Owing to the high quality er-ratic discharge of cullet quench waterfrom plants within this subcategory, noplants presently employ end-bf-pipetreatment. Best practicable controltechnology currently available would re--quire that a typical plant using 83401/metric ton (2000 gal/ton) of combinedprocess and non-contact cooling waterachieve effluent levels of 27 mg/I forsuspended solids and 10 mg/l for oil. Allfour of the plans for which effluent dataare available presently achieve the rec-ommended levels. These effluent levelsare readily achievable by all plants with-in this subcategory with a minimum ofin-plant control in the form of house-keeping techniques.

Th& best available technology eco-nomically achievable involves the segre-gation of the cullet quench from thenon-contact cooling water stream, therecirculation of the cullet quench waterstream, and treatment of the blowdown

from the cullet quench recIroulatlonsystem by diatomaceous earth filtra-tion. This will further reduce oil and sus-pended solids in the discharge streamto less than 5 mg/I and will reduce thecontact water discharge from 420 I/met-ric ton (100 gal/ton) to 21 1/metrIo ton(5 gal/ton).

(4) Recommended control and treat-ment-televslon picture tube envelopemanufacturing subcategory. Televisionpicture tube envelope plants currentlyemploy in-plant methods of water con-servation and end-of-pipe treatment forfluoride, lead, and suspended solids re-moval. All of the plants for which infor-mation is available treat abrasive andacid polishing waste waters by lime pre-cipitation with the pH being adjustedwhere necessary. It Is this technologyupon which the best practicable controltechnology currently available Is based,A typical plant discharging 4420 1/metrIcton (1060 gal/ton) of finishing wastewater would be required to achieve ef-fluent levels of 15 mg/I of fluoride and1 mg/l of lead for that waste waterstream. The same typical plant whichdischarges 12,500 I/metrIc ton (3000gal/ton) of finishing waste water andcombined cullet quench and non-contactcooling water would be required toachieve effluent levels of 10 mg/i of sus-pended solids and oil, 5.2 mg/l of fluoride,and 0.35 mg/I of lead In the total wastewater stream. All plants within this sub-category are either currently achievingthese levels or can achieve these levels byupgrading the operation of existing treat-ment systems and/or improving house-keeping to minimize pollutant discharge,

Best available technology economt-cally achievable involves the sand filtra-tion of the lime treated effluent to fur-ther remove fluoride and lead precipi-tates, and the passage of the effluentfrom the sand filter through a bed ofactivated alumina, thus further reniov-ing fluoride. This technology will allowthe typical plant to achieve effluent levelsof10 mg/I of oil, 5 mg/I of suspendedsolids; 0.71 mg/I of fluoride, and 0.035mg/1 of lead In the total dischargestream.

(5) Recommended control and treat-ment-incandescent lamp envelope man-ufacturing subategory. The present levelof treatment within the incandescentlamp envelope manufacturing subeate-gory involves oil separation and sedi-mentation applied to the cullet quenchwater stream and lime treatment forfluoride and suspended solids removalfrom frosting waste waters.

Best practicable control technologycurrently available includes the presentstate-of-the-art for treatment of wastewaters within the subategory and theaddition of steam stripping for ammonlaremoval and a recarbonatlon system forpH adjustment of the frosting wastewater discharge stream. A typical plantusing 4500 l/metle ton (1080 gal/ton) ofcombined noncontact cooling and oulletquench water would be required toachieve effluent levels of 25 mg/I of oiland suspended solids In this waste water

PROPOSED RULES

stream. The typical plant also discharges3420 /metric ton (820 gal/ton) of frost-ing waste water; effluent levels of 25 mag/Iof suspended solids, 20 mg/1 of fluoride,and 30 mg/1 of ammonia are readilyattainable after treatment of this wastestream. Plants not currently achievingthese effluent levels can add. to theirpresent treatment system an ammoniaremoval system and a recarbonation sys-tem and can upgrade their present sys-tems to optimize suspended solids re-moval by better controlling flocculation,adding polyelectrolyte or other coagu-lant aids recirculating sludge, or reduc-ing weir overflow rates.

Best available technology economicallyachievable includes the sand filtrationof the effluent from the lime precipita-tion system, activated alumina filtrationof the effluent from the sand filters, anddiatomaceous earth filtration of the cul-let quench waste water stream. Thistechnology will allow a typical plant toachieve effluent levels of 5 mg/1 for sus-pended solids and oil in the cullet quenchwaste water stream, and 5 mg/1 of sus-pended solids and 2 mg/I of fluoride inthe frosting waste water stream. Thesetechnologies are not current industrypractice but have been employed formany years in the field of watertreatment.

(6) Recommended control and treat-nent-hand pressed and blown glass

manufacturing subcategory. Very limiteddata are available on the hand pressedand blown industry with regard to efflu-ent discharge. Owing to the low wastewater volumes, the lack of sufficientquantities of cooling water that couldbe used for dilution, and the very limiteddata available, achievable effluent levelsin the hand pressed and blown glasssubcategory are expressed in terms ofconcentrations (mg/I). Waste waterconstituents requiring control are sus-pended solids, fluoride, and lead.

Best practicable control technologycurrently available requires that effluentconcentrations of 25 mg/I for suspendedsolids, 15 mg/1 for fluoride, and 1.0 mg/1for lead be attained. Most plants donot make leaded glass and for theseplants, lead is not a problem. Manyplants do not acid etch or polish glassand therefore, do not have a fluorideproblem. Methods of achieving-the bestpracticable control technology currentlyavailable include sedimentation, clarifi-cation, land disposal, improved house-keeping techniques, and batch limeprecipitation.

Best available technology economicallyachievable requires that effluent levels of5 mg/1 for suspended solids, 2 mg/Ifor fluoride, and 0.1 mg/i for lead beattained. This involves sand filtration inall cases, and the use of activated alu-mina to further remove fluorides in thosecases where hydrofluoric acid is usedto etch or polish glassware.

Solid waste control. The applicationof these technologies requires that solidwaste control be considered. Best practi-cable control technology and best avail-able control technology as they are

known today, require disposal of thepollutants removed from waste watersproduced within this industry segmentin the form of solid wastes or liquid con-centrates. In most cases these are non-hazardous substances requiring onlyminimal custodial care. However, someconstituents may be hazardous and mayrequire special consideration. In orderto ensure long-term protection of theenvironment from any hazardous orharmful constituents, special considera-tion of disposal sites must be made. Alllandfill sites where such hazardouswastes are disposed should be selected soas to prevent horizontal and verticalmigration of these contaminants toground or surface waters.

In cases where geologic conditionsmay not reasonably ensure this, ade-quate legal and mechanical precautions(e.g., impervious liners) should be takento ensure long term protection to theenvironment from hazardous materials.Where appropriate, the location of solidhazardous materials disposal sitesshould be permanently recorded in theappropriate office of legal jurisdiction.It should be noted that there Is no evi-dence that the application of the recom-mended control and treatment tech-nologies will result in any unusual solidwaste disposal problems.

(v) Cost estimates for control ofwaste water pollutants. The capital andtotal yearly costs to the pressed andblown glass segment of the glass manu-facturing category to achieve the pro-posed best practicable control tech-nology currently available effluent limi-tations guidelines are estimated to be$2.67 million and $0.966 million respec-tively. This estimate is based on theassumption that only surface ds-chargers are affected by the proposedguidelines. There are: (a) 55 knownglass container, (b) 23 known machinepressed and blown glass, (c) 9 knownglass tubing, (d) 4 known television pic-ture tube envelope, (e) 3 known incan-descent lamp envelope, and (1) 13known hand pressed and blown glassmanufacturing surface dischargers. Thisestimate of surface dischargers is basedon RAPP applications, industry supplieddata, and a survey of the pressed andblown glass segment The Agency Is re-questing additional information with re-gard to surface dischargers at this time.

The capital and total yearly costs tothe pressed and blown glass segment ofthe glass manufacturing category toachieve the proposed best availabletechnology economically achievable ef-fluent limitations guidelines are esti-mated to be $27.7 and $0.59 millionrespectively. This estimate is based onthe assumption that only surface dis-chargers are affected by the proposedguidelines with no credit given for thosefacilities which currently employ all ora portion of the best available tech-nology economically achievable. Thisestimate also includes those costs assocl-ated with best practicable control tech-nology currently available.

3O285

(vi) Energy requirements and ron-water quality environmental impacts. Itis estimated that the equivalent ofeighteen million and thirty-one millionilowatt hours of electricity are required

to achieve the best practicable controltechnology currently available and thebest available technology economicallyachievable, respectively. This amounts toa less than one percent Increase in anIndividual plant's current energy re-quirement In all subcategories with theexception of the incandescent lamp en-velope manufacturing subcategory. Thesteun stripping of ammonia, on whichbest practicable control technology cur-rently available for that subcategory isbased, is a high energy user and resultsn an eight percent increase over current

energy requirements. The 650 mag/1 rawwaste discharges of ammonia necessitateIts removal to ensure environmentalprotection.

With the exception of ammonia re-moval, required for the incandescentlamp envelope subcategory, there is noevidence that application of the proposedefiluent limitations guidelines will resultIn any unusual air or solid waste disposalproblems. The ammonia stripped fromIncandescent lamp envelope frostingwaste water. will be discharged to theatmosphere but methods are availableto reduce the concentrations to below thethreshold of odor.

(vii) Economic impact analsis. Apreliminary assessment of the effects ofBPOTCA, BATEA, and NSPS costs forthe industry indicated that only two ofthe si: subcategorie-machine pressedand blown glass manufacturing and handprezsed and blown glass manufacturing-could face potential impacts under theproposed guidelines. Hence, detailed eco-nomic analysis was carried out only forthose two sectors.

Adverse economic impacts as the resultof BPCTCA efiluent limitations guide-lines are expected to occur only in thehand prezzed and blown glass manufac-turing subcategory. Between 3 and 5closures are anticipated primarily be-cause of the inabijity of some firms inthis subcategory to raise the capital nec-esary to purchase Pollution controlsystems for treatment of hydrofluoricacid etching wastes. However, only 46percent of the hand pressed and blonglass manufacturing subcategory per-forms acid etching. The plants which donot acid etch will be able to meet theguidelines with a substantially lowercapital Investment.

The threatened plants represent be-tween 10 and 15 percent of segment ca-pacity and about '700 to 1,000 employees.In addition, some regional effects mayarise due to the fact that hand pressedand blown glass manufacturing plantsare concentrated in the Ohio-West Vir-ginia area. Price increases necessary torecover annual BPCTCA costs (includ-ing depreciation and cost of capital)should be modest-approximateiy Ipercent for those plants with acid etchingand about 0.9 percent for those plantswithout acid etching.

FEDERAL REGISTER, VOL 39, NO. 163-WEDNESDAY, AUGUST 21, 1974

30286

Plants in the incandescent lamp enve-lope manufacturing subcategory willhave to make significant expendituresto achieve BPCTCA effluent limitationsguidelines, but no adverse effects are ex-pected. The estimated price increase isabout 1.0 percent.

None of the remaining four subcate-gories-machine pressed and blown glassmanufacturing, glass container manu-facturing, television picture tube enve-lope manufacturing and glass tubingmanufacturing-should face any signifi-cant impacts under the proposedBPCTCA guidelines. This is based on theassumption that plants in these subcate-gories will be able to meet the proposedBPCTCA limitations without new in-vestment. Some industry comments statethat a few plants may, in fact, requiremodification in order to tomply withproposed BPCTCA limitations. TheAgency is requesting additional cost in-formation for such plants, and in theevent significant plant modification costsare identified, the impact analysis will bereevaluated..The proposed BATEA effluent limita-

The proposed effluent limitationsguidelines are not expected to have anynoticeable effect on balance of paymentsor overall industry growth, althoughgrowth in the machine pressed andblown glass manufacturing subcategorymay be hindered due to the diversion ofcapital into pollution control equipment.

The following responded with com-ments: U.S. Water Resources Council;Delaware River Basin Commission; Min-nesota Pollution Control Agency; Owens-Illinois; Glass Container ManufacturersInstitute; State of Michigan, Departmentof Natural Resources; General ElectricCompany; and North Carolina Depart-ment of Natural & Economic Resources.

The primary issues raised in the de-velopment of the proposed effluent limita-tions guidelines and standards of per-formance and the treatment of theseissues herein are as follows:

(1) A common criticism was that pre-treatment standards were omitted fromthe draft development document. It wasstated that both pretreatment standardsand effluent limitations guidelines werenecessary in order that the pressed andblown glass industry can make firm en-gineering and economic commitments.

It has been Agency policy to proposepretreatment standards at the time ofpromulgation of effluent limitationsguidelines. However, the Agency wouldwelcome, at this time, data or suggestionspertaining to pretreatment standards forthe pressed and blown glass segment ofthe glass manufacturing category.

(2) The comment was received thatthe data base on whichIthe guidelines arebased is inadequate and that the Agencyshould extensively sample the pressedand blown glass segment to develop amore thorough and reliable data base.

All available data pertaining to thepressed and blown glass segment hasbeen analyzed and engineering judg-ments made based upon this data. TheAgency feels that the data base is ade-quate but does solicit any additional datawhich supports or contradicts the find-ings expressed in the draft developmentdocument.

(3) The comment was made that theage of a facility should be a factor withregard to the suboategorization of thepressed and blown glass segment with-therecommendation that a range of valuesbe specified which would reflect the ageof an individual facility.

The available data does not supportthis contention. However, the Agency so-licits information which substantiatesthis clain Information showing the re-lationship of investment required to at-tain effluent limitations guidelines, wa-ter usage, or waste loadings to age of afacility would be particularly useful insupporting the hypothesis that age is animportant factor affecting subcategori-zation of the industry segment.

(4) An objection was made to the in-clusion of noncontact cooling water flowin the characterization of the typicaIplant on which the BPCTCA guidelinesfor the glass container, machine pressedand blown, television picture tube en-velope, and glass tubing manufacturingsubcategories are based. It was statedthat while on a weight basis the recom-

mended guidelines are achievable inmost cases, industry feels that concentra-tion limits will be violated when wastestreams are segregated and recirculationsystems are employed during the interimperiod between 1977 and 1983 in orderthat BATEA limitations be attained.

Effluent limitations guidelines will beapplied consistent with a schedule ofcompliance leading to achievement oflevels of abatement required by the Act.Such limitations as are required by efflu-ent limitations guidelines will be statedin quantitative terms, i.e., unit of weightper unit of time (kg/day) for each pol-lutant limited. Qualitative limitations(i.e., concentration) set at a fixed levelare not consistent with fixed quantitativelimitations in a variable or reducing flowcontext, but may be required by State au-thority preserved under Section 510 ofthe Act. In such a situation, the morestringent effective limitation would beobserved.

(5) The comment was made that the20 mg/l level for fluoride which the draftdevelopment document states that thetypical incandescent lamp envelope man-ufacturing plant can achieve is toostringent and inconsistent with anNPDES permit which Is now being writ-ten. The commenter recommended thatthe 32 mg/l level which their plant is nowachieving is a more realistic level.

The development document presentsfindings, of an extensive survey of theentire subcategory rather than of a sin-gle plant. The available data supportsthe proposed effluent limitations guide-lines.

(6) The comment was made that be-cause no plants in the incandescent lampenvelope manufacturing subcategory arecurrently treating the 650 mg/1 concen-trations of ammonia discharged by thetypical plant, ammonia removal tech-niques are not best practicable controltechnology currently available and untilmore research is done, do not even qual-ify as best available technolo3y econom-ically achievable.

The high levels of ammonia whichoccur in waste waters associated withthe incandescent lamp envelope manu-facturing subcategory are capable ofproducing adverse biological effects. Thepresent degree of treatment-within thissubcategory has been Judged to be In-adequate with regard to ammonia re-moval. Many ammonia removal tech-niques exist and the deficiency of plantswithin this subcategory with regard totreatment of ammonia necessitates atransfer of technology from other pointsource categories. Waste waters fromplants within this subcategory are cur-rently treated to remove fluorides by theaddition of lime to a PH of 11 causingthe precipitation of calcium fluoride.This high pH makes the air or steamstripping of ammonia a rather attractivemethod of treatment. The technique onwhich effluent limitations guidelines arebased Is steam stripping which Is well-demonstrated in the fertilizer, petroleumand petrochemical and steel industries.

30-987

(7) The comment was made that theproposed recommendations for BATEAwill result In essentially zero dischargeof pollutants and the need for the opti-mistic technology transfer predictionsand the extremely low effluent levelsrecommended was not understood.

The Act declares that the national goalIs the elimination of discharge of pol-lutants by 1985. The proposed effluentlimitations guidelines fulfin the require-ment of progress toward this nationalgoal. The technoloaes on which BATEAeffluent limitation guidelines are basedare well demonstrated by their applica-tion to treatment of waste waters asso-elated with other industrial categoriesor application in the field of watertreatment.

(8) The comment was made that thecosts presented in the draft developmentdocument for typical plants are not rep-rezentative of all the plants Witlhn thevarious subcategories.

The technologies currently employedby plants within these various subcate-gorles of the pressed and blown glasssegment are considered acceptable asBPCTCA. There Is therefore, no expectedsignificant increase in capital invest-ment, the only requirement being thatplants operate existing pollution controland treatment equipment properly or im-prove houseLzeeping techniques to con-trol raw waste loadings. The Agency does,however, solicit data which support orcontradict this contention. The fact thatthe recommended levels are achievableIs demonstrated by the high percentageof plants for which data Is available thatcurrently meet the BPCTCA require-ments.

Interested persons may participate inthis rulemaking by submitting writtencomments in triplicate to the EPA Infer-mation Center, Environmental Protec-tion Agency, W-1hington, D.C. 20460.Attention: mr. Philip B. visman. Com-ments on all aspects of the proposedregulation are solicited. In the eventcomments are in the nature of criticismsas to the adequacy of data which areavailable, or which may be relied uponby the Agency, comments should iden-tify and, it possible, provide any addi-tional data which may be available andshould indicate why such data are essen-tial to the development of the regula-tions. In the event comments address theapproach taLen by the Agency in estab-lsbhing an effluent limitations guidelineor standard of performance, EPA solicitssuggestions as to what alternative ap-proach should be taken and why andhow this alternative better satisfies thedetailed requirements of sections 301,304(b), 306, and 307 of the Act.

representing the degree of ellluentreduction attainable by the applict-tion of the be4,t praclicable controltechnology currently available.

In establishing the limitations setforth in this section, EPA took into ac-count all information It was able tocollect, develop and solicit with respectto factors (such as age and size of plant,raw materials, manufacturing proceses,products produced, treatment technologyavailable, energy requirements and costs)which can affect the Indus-try subcatc-gorization and effluent levels established.It is, however, possible that data whichwould affect these limitations have notbeen available and, as a result, thesolimitations should be adjusted for cer-tain plants in this industry. An Individ-ual discharger or other interested per-son may submit evidence to the RegionalAdministrator (or to the State, If theState has the authority to Issue NPDEpermits) that factors relating to theequipment or facilities involved, theprocess applied, or other such factorsrelated to such discharger are funda-mentally different from the factors con-sidered In the establishment of theguidelines. On the basis of such evidenceor other available information, theRegional Administrator (or the State)will make a written finding that suchfactors are or are not fundamentallydifferent for that facility compared tothese specified in the Development Docu-ment. If such fundamentally difterentfactors are found to exist, the RegionalAdministrator or the State shall estab-lish for the discharge effluent limita-tions in the NPDES permit either moreor less stringent than the limitationsestablished herein, to the extent dictatedby such fundamentally different factors,Such limitations must be approved by theAdministrator of the Environmental

representing the degree of effluentreduction attainable by the applica-tion of the best practicable controltechnology currently available.

In establishing the limitations set forthin this section, EPA took into account allInformation it was able to collect, developand solicit with respect to factors (suchas age and size of plant, raw materials,manufacturing processes, products pro-duced, treatment technology available,energy requirements and costs) which

can affect the Industry subeategorlzationand effluent levels established. It is, how-ever, possible that data. which would af-fect these limitations have not beenavailable and, as a result, these limita-tions should be adjusted for certainplants in this Industry. An individualdischarger or other interested personmay submit evidence to the RegionalAdministrator (or to the State, if theState has the authority to issue NPDESpermits) that factors relating to theequipment or facilities involved, theprocess applied, or other such factors re-lated to such discharger are fundamen-tally different from the factors consid-ered in the establishment of the gulde-lines. On the basis of such evidence orother available information, the ReglonalAdministrator (or the State) will make awritten finding that such factors are orare not fundamentally different for thatfacility compared to those spccifled inthe Development Document. If such fun-damentally different factors are foundto exist, the Regional Administrator orthe State shall establish for the dis-charger effluent limitations in the NPDESpermits) -that factors relating to thepermit either more or less stringent thanthe limitations established herein, to theextent dictated by such fundamentallydifferent factors. Such limitations mustbe approved by the Administrator of theEnvironmental Protection Agency. TheAdministrator may approve or disap-prove such limitations, specify other lim-itations, or initiate proceedings to revisethese regulations.
