Tlie Administrator published in the Federat, ItcmcTcn of January l(i, 1973, (38 IB 19114) a list of 27 source cate gories, including the organic chemicals manufacturing category. The ugulalious proposed herein set forth the standards of performance applicable to new sources for the nonaqueous proc esses subcategory (Subpart A), processes with process water contact as steam diluent or absorbent subcategory (Sub part R), aqueous liquid phase reaction systems subcategory (Subpart C), and batch and semicontinuous processes sub category (Subpart D) of the organic chemicals manufacturing category. Section 307(C) of the Act requires the Administrator to promulgate pretreat ment standards for new sources at the same time that standards of perform ance for new sources are promulgated pursuant to section 306. Sections 414.15, 414,25, 414.35 and 414.45 proposed below provide pretreatment standards for new sources within the nonaqueous processes subcatcsory (Subpart A), processes with process water contact as steam diluent or absorbent subealegory (Subpart B), aqueous liquid phase reaction systems subcategory (Subpurt C), and batch and semicontinuous processes subcate gory (Subpart D) oi the organic chemi cals manufacturing category.

The point sources category wavs first studied for the purpose of determin ing V'hethcr separate limitation.1; and standards are appropriate for du; front .-cements withm the category. This analysis included a determination of wheihcr differences in raw material used, product produced, mnnulaclunivr process employed, acre, size, waste water nn".l:tuen'-s and oilier iactors require development oi separate limitations and s Lauda ids for riiifoient segments ol the Point- source category. The raw waste characteristics for each such segment were then identified. Tins included an analysis of (1) the source, flow and volume of water used in the process employed and the sources of waste and waste waters in the operation; and (2) tlie constituents of the waste which should be subject to effluent limitations guidelines and standards of perform ance'were identified. The control and treatment tech nologies existing within each segment were identified. This included an iden tification of each distinct control and treatment technology, including both in- plant and end-of-process technologies, which are existent or capable of being designed for each segment. It also in cluded an identification of, in terms of the amount of constituents and the chemical, physical, and biological char acteristics of pollutants, the effluent level resulting from the application of each of the technologies. The problems, limita tions and jeliability of each treatment and control technology were also iden tified. In addition, the nonwater quality environmental impact, such as the eifects of the application of such technologies upon other pollution problems, including air, solid waste, noise and radiation, was identified. The energy requirements of each control and treatment technology were determined, as well as the cost of the application of such technologies. The informal ion, as outlined above, was then evaluated in order to determine what levels of technology constitute the "best practicable control technology cur rently available," "best available tech nology economically achievable" and the "best available demonstrated control technology, processes, operating meth ods, or other alternatives." In identifying such technologies, various factors were considered. These included the total cost of application of technology in relation to the effluent reduction benefits to be achieved from such application, tlie age of equipment and facilities involved, the process employed, the engineering as pects of the application of various types of control techniques, process changes, nonwater quality environmental im pact including energy requirements and other factors. Tlie data on which the above analysis was performed included EPA permit ap plications, EPA sampling and inspec tions, consultant reports, and the indus try submissions. The pretreatment standards proposed herein are intended to be complementary to the pretreatment standard proposed for existing sources under of 40 CFR FEDERAL REGISTER, VOL. 38, NO. 241--MONDAY, DECEMBER 17, 1973 /CCR 000036417 PROPOSED RULES 3-5707 Part 123. The buds for such standards is set forth m the Fepuka), liKC-LyrEx of July 1.9, 1973, 32 I'll 19233. The.-provisioiiA of Part 323 arc equally BPiSJcable to fourees which would cihs!:ilui*r "new sources," under section 203 if they were to discharge pollutants directly to navi gable waters except for 5 123.133. That section provides a prclrcatn-.ent standard for "incompatible nollutmirs" and re quires implication of tlie "last practica ble control tecimoloey currently avail able," subject to an adjustment for amounts of pollutants removed by the publicly owned treatment works. Since the pretreatment standaicls proposed herein apply to new sources, S 414.15, 414.25, 414.35 and 414,45 below amend 5 123.133 to require application of the standard of performance for new sources rather than the "brat practicable" stand ard applicable to dusting sources under sections 301 and 301 (b) of the Act. (2) Summary of conclusions with re spect to .the nonaqueous processes subcategory (Subpart A), processes with process water contact as steam diluent or absorbent subcategory (Subpart R), aqueous liquid phase reaction systems subcatop.ory (Buboart C), and batch and seinicontinuous processes subcategory (Subpart D) of the organic chemicals manufacturing category.

The organic chemical Industry' in the United States Is a complex matrix in which interrelated chemicals compete for raw' materials and markets via increasingly competitive technologies. The water use. and sub sequent waste water discharges within the Industry are closely related to this mix of products and manufacturing processes. The structure of the industry can be studied by several approaches. 'There are some companies which specialize in making products for use by another in dustry, while other firms specialize in the production of com noun.in having com mon chemical functional j. roups or com pounds made by similar unit processes. The concept of horizontal integration is a strong motivating force in the be havior of many companies which pro duce several products with a common end use. By maintaining a position in each of there products, a company pro tects Itself against intrusion into these common end use markets. Another major influence has been the need for vertical integration. Firms that until recently were content to produce intermediate or end products, have been under constant pressure either to integrate backwards by acquiring their own sources of raw materials or to integrate forward by gaining control of their customers. Backward integration within the in dustry has in turn been affected by the changing availability of economical raw materials. Prior to World War II, the organic chemicals Industry relied pri marily on feedstocks derived from coal. After World War IT, more readily proc essed feedstocks were introduced in the form of refinery dry gas and olefins. These became available through the growth of catalytic cracking installations for gasoline manufacture in refinery operations. This kind of feedstock was in turn re placed, storting in tlie early 3950's, by a low priced liquid petroleum gas ChPG) by-product (ethane and propane) from a rapidly expanding natural gas indus try based on the Cuif Coast. During the decade of the 1960's the rapid growth uf the industry was twice that of the source of its feedstock supply, natural gas. Tins situation has led to the increased use of distillates derived from crude oil (naphtha) as feedstocks. Currently, there is sharp competition within the industry for both of these feedstocks. Tlie competition has been in tensified by alternate uses for them out side the organic chemicals industry. In the past, the natural gas industry has found advantages in selling ethane and propane for chemical usage. How ever, the drastically increased demand for pollution free sources of fuel has completely changed this picture. Tight liquid distillates derived from crude oil have an alternative use and value in gasoline. This has led to sharp competition between chemical producers and oil reimers for the same barrel of crude oil. A given set of feedstocks, intermedi ates, and products associated with the operation of any specific facility repre sents the sum of these considerations as they relate to mi individual company. Each plant's set of process" operations and production is a unique contribution to a profitable operation. The term "production" must be accu rately defined when applied to a chemical plant. It is erroneous to base production only on those commodities which are finally shipped across plant boundaries for sale. Tne true production associated with any given plant must include the captive utilization of feedstocks and intermediate processing steps between the initial feedstock (c.g. IPG, naphtha) and final products. Each process is itself a series of unit operations which effect chemical and physical changes In the feedstock or products. In the commercial synthesis of a simple product from a single feedstock, there are normally sections of the proc ess associated with the preparation of the feedstock, the chemical reaction, the sep aration of reaction products, and the final purification of the desired product. Each unit operation may have drastically different water usages associated with it The type and quantity of waste water produced by a given iacility is therefore directly related to the nature of the various processes within its boundaries. Tlie production from a given process module is related to the design capacities of the individual unit operations within it. In many cases, some unit operations such as the central reaction, are carried out in several small reactors -operating in parallel. The flow of material between unit op erations within a process may be either a continuous stream or through a series of batch transfers. Both types of proc esses normally have an associated design capacitv, which can be expressed as mil lions of pounds of product r>cr year. Tire actual rede at which a product is produced may be higher or lev. or than the rated capacity, depending cm such factors as down time (for maintenance, catalyst regeneration, etc.). process "de bottlenecking", variations in feedstock availability, and product demand. To insure the smooth operation of tire different segments within a producing facility, manufacturers maintain inven tories of the amounts of feedstock, inter mediate products, and final products available for subsequent reaction or ship ment from the plant. Depending on tiio nature of the operation, these inventories are updated on a monthly, weekly, or even daily basis. Tire examination of his torical production inventories and asso ciated manufacturing processes for a given facility provides the most mean ingful picture of the activities within its boundaries. This is directly related to the type and quantity of wastes which are generated. (ii) Categorization. The organic chem icals manufacturing category consults of approximately 260 product commodifies listed under the Governments Standard Industrial Classifications (SIC) 2555 (formerly SIC 2815), Cyclic Intermedi ates, Dyes, Organic Pigments and Coal Tar Crudes, and SIC 2360 (formerly SIC 2818), Industrial Organic Chemicals not elsewhere classified. Of these 260 prod uct commodities listed under SIC 2365 and SIC 2869, 210 significant product commodities, which are manufactured by 2G9 processes, were identified. These product-process segments are estimated to comprise greater than 99 percent of the Industry's production capacity. From the list of 269 significant product-process segments, 41 major product-process seg ments were selected, as they represent approximately 75 percent of the Indus try's production capacity. These productprocess segments are presented in Table I. Effluent limitations, as set forth in these regulations (Part 414), are appli cable to the product-process segments shown in Table L Taels I SUECATEGOHY A NONAQUEOUS PROCESSES MAJOR PRODUCTS AN;) PROCESSES Product Cyclohexane Ethyl Benzene-----Vinyl Chloride------ BTX Aromatics-- BXX Aromatics___ Process Hydrogenation of Ben zene.

SUBCATECORY D BATCH AND SEMICONTIN IJOTJS Processes Major Products and Processes Organic Dye Products: Azoic Dye3 and Components. The organic chemicals manufacturing category was subcategorized by the iden tification of four major process related subcategories in which all 269 product- process segments were classified. Subcategories A, B, and C are comprised of continuously operated processes. Sub category D Is comprised of batch and semicontinuous processes. Each subcate- goiry is defined on the basis of manufac turing process technology and process w$ste water generated. These subcategalries are defined as follows: (1) Subpart A--Nuna'ntc.otis processes subcategory: These processes have mini mal contact between water end reactants Of products within the rn'-Tss. Water is not required a reactant or diluent and is not lornud as a xeactian product. The only wrier usage steins from periodic washes of working fluids or catalyst hydration. <2) Subpat t. li--Pro-.e-'ses with process water contact as steam diluent or 0L>sorbent subce.it gory: Process water usage is in. the form of dilution steam, direct contact quench, or as an absorbent for reactor eriuent gases. Reactions are all vapor-phase and carritd out over solid catalysts. Alo.-t processes have an ab sorber coupled with steam stripping of chemicals for purification and recycle. (3) Subpart C--Aqueous liquid-phase reaction systems subcuicgory: These are liquid-phase reactions where the catalyst is generally i;.i aqueous media sucli as dissolved or emulsified mineral salt, or acid and caustic solutions. Continuous regeneration of catalyst system requires extensive water usage. Substantial re moval of spent inorganic salt by-products may also be required. Working aqueous catalyst .-oluvion is normally corrosive. Additional process v/aler is required in final purification or neutralization of products. <4) Subpart D--Batch and semicon tinuous processes subcatcgory: Processes are carried out in reaction kettles equipped with agitator;,, scrapers, rciltix condensers, etc. depending on the nature of the operation. Many reactions are liq uid-phase with aqueous catalyst systems. Reactants are transferred to batch reac tors by gravity flow, pumping, or pres surization with air or inert gas. Much of the material handling is manual, and there is limited use ol automatic process control. Filter presses and centrifuges are commonly used to separate solid products from liquid. Where drying is re quired, air or vacuum mens arc used. Cleaning of noucontinuous production equipment consulates a major source of process waste water. Due to the large range of raw waste loads for product-process segments in subcategories B and C, it was necessary to establish diluent limitations within each of these subcategories. This was accomplished by determining the median raw waste loads of product-process seg ments in each subcategory. Productprocess segments with raw waste loads below the median value were subse quently designated K1 and Cl respec tively'. Those product-process segments with raw waste loads above the median value were designated E2 and C2 respec tively. (lit) Constituents of waste water pol lutants, in determining the major pollut ants and effectiveness of various treatment alternatives, the following pol lutant parameters were measured: bio chemical oxygen demand (BODS). chem ical oxygen demand (COD), total organic carbon (TOC), total suspended solids (TSS), phenols. pH, cyanide <CN), am monia (NII.J), total kjeldahl nitrogen (TfCN), extractable oils, sulfate, total uhospbrnis (TP), nine (Zn), copper (Cu), iron 'Fe), chromium (Cr), and cadmium <Cd>. It was determined that dissolved or ganic chemicals constitute the maior pollutant source in this industry. The following pollutant parameters were se lected on this basis: Biochemical oxygen demand iBODj), chemical oxygen de mand (COD), total suspended solids (TSS), and phenols. Other pollutant pa rameters were found to lie less significant in the raw waste loads or treated diluent. Effluent limitations have not been es tablished for cyanide (CN> and cadmium (Cd) although trace quantities of these pollutants were found in certain process waste streams. Significant reductions of these pollutants are expected to occur after cnd-of-proce&s treatment by best practicable control technology currently available. <iv) Cost and energy requirements. Capital and annual end-of-proccss treat ment costs have been estimated for each level of technology and arc presented in the Development Document. These costs were also estimated by treatment plant size with treated effluent flow's: 0.012, 0.36, 0.72. and 2.1G million gallons per day. Annual costs were also calculated per 1000 gal treated effluent and per pound of BODS removed. Total industry cost for best practicable control technology currently available is estimated at 61,030 million ("Economic Impact of Water Pollution Control on the Organic chemicals Industry," Ar thur D. Little, Inc., Cambridge, Mass., 1973). This cost includes a substantial portion of capital (approximately 25 per cent) which has been invested as of 1973. Annual energy requirements for best practicable control technology currently available (BPCTCA) treatment and con trol are estimated to be 2 trillion BTU (600 million Kwh) for the entire in dustry. This is relatively insignificant (less than 1 percent) when compared to the total energy requirements for this industry. (v) Nonwater quality environmental impact. 'Die major nonwater quality consideration which may be associated with in-process control measures is the use of alternate means of ultimate dis posal. As process raw waste loads are reduced in volume using water conserva tion and reuse, industry may wish to decide on alternate disposal technologies such as incineration, ocean discharge, deep well injection, and land disposal. Each of these alterantives must be eval uated on a case by case basis within EPA's policy and statutory requirements for air quality, ocean, deep well, and land disposal. No increased air pollution problems should develop as a result Of water treat ment processes. Solid wastes will increase as a result of the removal of suspended solids from process waste water. Best practicable control technology and best available control technology as they are known today, require disposal of tire pollutants removed from waste waters In this in dustry in the form of solid wastes and FEDERAL REGISTER, VOL. 3C, NO. 241--MONDAY, DECEMBER 17, 1973 CCR 0000364-19 PRQPGCUD RUt.ES 34709 liquid eorventrates.

The best piaeneable control tech nology currently available (BPCTCA) has been unilormly deiined for all lour major subcatc 'oric- m hie o; t-cnic chem icals nirautiacuumg induriiy as biologi cal waste treatment. In determining this technology, it was lirst necessary to deter mine the performance of exemplary bio logical waste treatment systems, These systems consist of various combinations or biological processes: activated sludge, activated sludge preceded by trickling fil ters, aerated lagoons, anaerobic and aerobic lagoons, and activated sludge fol lowed by aerated lagoons. Tne following model system was used for coct estimat ing purposes and does not limit the BPCTCA solely lo these processes: equal ization with pli control and oil separa tion, activated sludge with chemical addition of coagulants to aid in clarifica tion of suspended solids. Effluent limita tions based upon the application of BPCTCA biological treatment systems do not preclude the use of equivalent chem ical-physical or other treatment systems wherever applicable. Determining the best available dem onstrated control technology (BADCT) for new organic chemical manufacturing sources Involved the evaluation of the best in-process control measures and end-of-proecss technologies. Some inprocess controls which would Involve the most exemplary practice arc as follows: (a) The substitution of nonprocess contact heat exchangers (using air, water or refrigerants) for direct contact water cooling (barometric condensers); (b) Hie use of nonaqueous quench media (e.g. hydrocarbons such as furnace oil) as a substitute for water, where di rect contact quench is required: (c) The recycle of process water, such as between absorber and stripper; . (d) The reuse of process water (after treatment) as make-up to evaporative cooling towers through which noncontact cooling water Is circulated; <c) The vr- of ivoctzs water to pro duce low preiRurc fleam by noncontact heat exchangers in roiicx condensers or chsiillTion columns; t/> Ti.'j recovery of .-'pent acid or caustic solutions '.or reuse; (r/i The rccoic-ry and reuse of spent catalystdurians: </(' The two oi nonaqueous solvents for ic.iracnon of product'..

Although biological trearinoni he.s been I'lescrilwu as the basis for the DAHCT, it is I'f'vc'gniz&d that, chemical-physical systems such as activated carbon may e.lso be employed as an end-nf-process technology or as an in-process recovery system, it may also be necessary to re move certain v asees which arc harmful to or interfere with' hiologi>r>l waste treatment systems by m-pro'arss chemi cal physical control processes. In betr-rmiiung the best available technology ccononucnily achievable for all sources by H'W, it was necessary to evaluate cue best, control and treatment technologies. This analysis was focused on tire n ciuciton oi the major pollutant, dissolved organic chemicals as measured by the chemical oxygen demand (COD) analysis. Applicable in-process controls as previously described for the BADCT maximize the reductions of raw wastes, particularly from harmful and biorelractory .sources. The model end-ofproccss system for all four subcategories involves addition of activated carbon to the biological waste treatment model for BADCT. As previously emphasized, this model does not preclude the use of equivalent systems. It has been recog nized that in-procer.s controls are fre quently used to recover products or by products and remove substances which interfere with biological treatment sys tems. These In-process systems may pre clude the need for additional end-ofprocess activated carbon treatment. Cvil) Effluent limitations are based upon the median raw waste load data for each suoeategory and the degree of re duction attainable by each treatment and control technology. Tne following pollutant parameters were limited by application of BPCTCA: biochemical oxygen demand, 5 day, total suspended solids (T3S), and phenols. Hie same pollutant parameters are limited for the new7 sources (BADCT) and best avail able technology economically achievable (BATEA) with the addition of a limita tion for chemical oxygen demand (COD).

Public- comments cn all these suggestions are solicited. (1) Most commontors expressed gen eral agreement that the process oriented categorization system is reasonable, ex plains raw waste load variations to a rea sonable extent, cud is useful in sim plifying what is universally understood to i be ft complex industry. Some commtiuteiv. questioned the loci: ol considcrai.iqn ior factors such r.s age, size oi plants, location, waste load variations within cakgoiies, and waste load treatability. trite analysis used in categorizing the industry shows that tho suboetogones adequately characterize the industry as t.opirccess technology and raw waste load variations. Hence, this approach will be followed. Additionally, the subcategories also explain to a large extent factors such tw o ge, location, size, treatability, and raw ws'.to load variations. Age of plant is & on er?.!!y not considered to be a relevant factor for most chemical plants since the iiwlu'.fi-y is constantly in the state of technologies'! change. Subcategory A and K jj^oduct-processes are common to large pel renkemien! plants located in the South and Gulf CoaT areas. These plants are characteristically lruge volume opera tions employing the latest control tech nology. Subcategory C product-processes comprise a large mixture of processes (aqiaous phase reactions) and raw waste load.-,.

Finally, effluent limitations were deter mined from reductions of raw waste loads achievable by tho apuueation BFCTCA c-ud-of-proees.; waste treatment fg stems. (3) Some common'trs expressed the view that the organic chemicals manu facturing industry is too complex for effluent limitations and standards and that the intent of the lew would bo ful filled by publishing only guidelines. Section 301 requires the achievement by July 1, 1977 of "effluent limitations'' for point sources. Data obtained for major segments of this industry lias indi cated that a "range'' of achievable limitations is not necessary. In develop ing effluent limitations and standards, the organic chemicals industry was first cate gorized. These factors were also evalu ated: ago, eizc of plant, location, process, raw waste, treatability, the full range of control and treatment technologies and treatment process variability. Industry categorization and subsequent effluent limitations contained in Bart -114. do-not require further consideration and vari ance as a result of these factors. Daily maximum and monthly maximum limita-f tions wore based upon normal treatment variations resulting from temperature, wasteland, operations, testing and other factors which were observed from prop erly designed and operated waste treat ment facilities. (4) Many commentcrs disagreed with the contractor's recommendation of BOD5, TOO and COD limitations for the best practicable control technology cur rently available. The biochemical oxygen demand parameter (BOD5) was determined to be the more appropriate oxygen demand pollutant parameter for biological waste treatment systems as recommended for BPCTCA. Other pollutant parameters such as chemical oxygen demand (COD) and total organic carbon (TOC) measure the non-biodegradablo as well as the bio degradable pollutants in waste streams. It is not possible, at tllis time, to establish a direct relationship between BOD5, COD, and TOC that would be appropri ate for the various mixtures of pollutants waste treatment plants. in the treated effluent from biological (2) Most coimnenters questioned the treatment systems.

The purpose of this notice is to estab lish final effluent limitations guidelines for existing sources and standards of performance and pretreatment stand ards for new souice.; in the inorganic chemicals manufacturing category of point source;, by amending 40 CFR Chapter I, Subehapter N, to add a new Lart 415. This final rulemaking is pro mulgated pursuant to sections 301, 304(b) and (c), 303(b) and (c.) and 307(c) of the Federal Water Pollution Control Act, as amended, (the Act) ; 33 U.S.C. 1331, 1311, 1314tb) and (c), 1310(b) and (c) and 1317(c): 86 Stat. 810 ct sen.; Pub. L. 93-500. Regulations regarding cooling water intake structures tor all categories of point sources under section 316(b) of the Act will be promulgated in 40 CFR Part 403. In addition, the EPA is simultaneously proposing a separate provision which ap pears in the proposed rules section of the Federal Register, stating the applica tion of tile limitations and standards set forth below to users of publicly owned treatment works which are subject to pretreatment standards under section 307(b) of the Act. The basis of that pro posed regulation is sot forth in the asso ciated notice of proposed rulemaking. The legal basis, methodology and fac tual conclusions which support promul gation of this regulation were set forth in substantial detail in the notice of public review procedures , published August 6, 1973 (38 FR 31202) and in the notice of proposed rulemaking for the aluminum chloride production sub category, aluminum sulfate production subcategory, calcium carbide production subcategory, calcium chloride production subeategory, calcium oxide and hydrox ide production subcategory, chlorine and sodium or potassium hydroxide pro duction subcategory, hydrochloric acid production subcategory, hydrofluoric acid production subcategory, hydrogen peroxide production subcategory, nitric acid production subeategory, potassium metal production subcategory, potassium dichromate production subeategory, po tassium sulfate production subcategory, sodium bicarbonate production subcatcgory, sodium carbonate production subcategory, sodium chloride production subcatcgoi-y, sodium bichromate and sodium sulfate production subcategory, sodium metal production subcategory, sodium silicate production subcategory, sodium sulfite production subeategory, sulfuric acid production subcategory, and titanium dioxide production sub category. In addition, the regulations as proposed were supported by two other documents: (1) The document entitled "Development Document for Proposed Effluent Limitations Guidelines and New Source Performance Standards for the major inorganic products Segment of the Inorganic Chemicals Manufacturing Point Source Category" (August 1973) and (2) the document entitled "Eco nomic Analysis of Proposed Effluent Guidelines. Inorganic Chemicals, Alkali and Chlorine Industries (Major Prod ucts) (August, 1973). Doth of these documents were made available to the public and circulated to interested per sons at aoprixmately the time of publi cation of the notice of proposed rulemaking. Interested persons were invited to par ticipate in the rulemaking by submitting written comments within 30 days from the date of publication. Prior public par ticipation in the form of solicited com ments and responses from the States, Federal agencies, and other interested parties were described in the preamble to the proposed regulation. The EPA has considered carefully all of the comments received and a discussion of these com ments with the Agency's response thereto follows. The i emulation as promulgated contains some signilicant departures from the proposed regulation. The fol lowing discussion outlines the reasons why these changes were made and why other suggested changes were not made.

Tire following is a summary of the sig nificant comments and the Agency's re sponse to those comments. (1) Because of wide variations in plant age and size, product ii-ix, manufactur ing processes, and raw materials, the guidelines should be expressed as ranges. Many eommenlers recommended adop tion of EGWQIAC's proposed methodolo gy. The approach taken in developing effluent limitations guidelines and stand ards of performance for the inorganic chemicals manufacturing industry was to examine all variables and segment the industry Into workable subcategories consistent with these variations. Twentytwo subcategories have been established based on the chemical product manufac tured. In cases where two dissimilar proc esses are used to manufacture the same product, separate limitations have been established within the subcategory. Thus, ranges are provided for, as are other fac tors, by segmenting the inorganic chem icals manufacturing point source cate gory into discrete subcategories, each with its own limitation. ESWQIAC's pro posal is under evaluation as a contribu tion toward future refinements on guide lines for some industries. The committee has indicated that their proposed meth odology could not be developed in suffi cient time to be available for the current phase of guideline promulgation, which is proceeding according to a court-or dered schedule. Its present state of de velopment does not provide sufficient FEDERAL REGISTER, VOL. 39, NO. 49--TUESDAY, MARCH 1 i, 1974 CCR 000036429 RULES AND REGULATIONS 9613 evidence to warrant the Agency's delay that the initial estimates arc low, the place of bauxite which significantly ef ing issuance of any standard in hopes figures have been revised and the pro fects the raw waste load.

The pollutants presenv in the waste water generated by the manufacture of inorganic chemi cals have been identified. Discharge of these pollutants to municipal treatment systems is allowed in limited quantities so as to ensure adequate treatment and to prevent interference with the per formance of such a system. These pre treatment standards for existing point sources are being proposed as an amend ment to 40 CFR Part 415. (4) Many conunenters stated that the cost estimates were low and did not in clude costs for auxiliary equipment, land acquisitions, sludge disposal, or research and development work. Additionally, it was said that the impact of these costs has been understated. Cost information was obtained directly from Industry during plant visits, from engineering firms and equipment sup pliers, and from available literature. This data has been obtained from the best sources available to the Agency and is believed to bo representative of actual capital and operating costs. In cases where conunenters have sup plied additional cost data, satisfactorily documented and detailed, to Indicate certain cases an effluent limitation may be adjusted to take into account pol lutants entering with a discharger's sup ply providing the water is withdrawn from the same source into which it is discharged. If the source is other than the receiving waterbody, the effluent standards will be applied as absolute limitations without adjustment. <7) Aluminum chloride. Some commenters said that a market may not exist for the scrubber water (a 23 percent aluminum chloride solution) and that costs to purify and concentrate the solu tion may be prohibitive. They recom mend a discharge allowance be made for the scrubber waste water effluent. Only "yellow grade" aluminum chlo ride, made with an excess of chlorine, re quires wet scrubbing techniques on the gaseous waste stream. Two plants, rep resenting approximately 40 percent of the total annual production of aluminum chloride, currently are able to sell their dilute scrubber solution. A rc-evaluation of the costs to concentrate the dilute scrubber solution indicates that costs for concentration are approximately 0.4 per cent of the selling price of aluminum chloride. (8) Aluminum sulfate. Some commenters stated that recycle of leaks and spills may contaminate high purity grades of product. Also, aluminum clays may be used as the raw material In standards consider it a ferroalloy: fb) all plants are members of Ferroalloy As soc.; (c) it Is usually made in complexes with ferroalloys; (d) it uses .similar processes in similar ovens. Commentors also expressed concern that the only two plants achieving the proposed guide lines are unique, using an uncovered furnace. Other plants recover gaseous carbon monoxide and must scrub the gas to remove impurities. Because of high temperatures dry bag collection of dust is not feasible. A portion of calcium carbide is pro duced in both the ferroalloy industry and the inorganic chemicals industry. The regulation presented heroin is r.pplieab'e to discharges from calcium carbide pro duction in open furnaces. Plants em ploying this manufacturing process are not located tn ferroalloy complexes. Ef fluent limitations for waste water dis charges from calcium carbide production in covered furnaces will be established in a forthcoming regulation as part of the ferroalloy industry. This distinction will accommodate differences in process waste water from plants using open fur naces and those using covered furnaces. CIO) Calcium oxide and calcium hy droxide. Many commcnters mentioned that costs for converting to a dry bag house from a wet scrubber system are economically unjustified.

The process waste water should be segregated from other waste streams and may be collected and fed recommended in Standard Methods for Waste Water Analysis. The guidelines do not require the sale of sodium sulfate. Satisfactory land disposal of the unused sodium sulfate would cost approximately two percent of the selling price of sodium sulfite. Tiie waste waters may be segre gated, treated and recycled to the process. (18) Sodium carbonate. Some com back into the manufacturing process. menters stated that gravity sedimenta tion will not reduce the suspended solids concentration to the recommended 25 mg/1 concentration. They say particles are very fine and a filter precoat is re quired. A small suspended solids reduc tion is not justified by the cost. Various manufacturers recommend using a sus pended solids concentration of 50 mg/1 as it is compatible with actual settling pond performance and is a move "real istic and achievable level". The treatment technologies required to attain the affluent pollutant reduction proposed are conventional and proven treatment systems. Treatment alter natives include sedimentation basins, fiocculators and clarifiers, (19) Sodium dichromate. Some com menters mentioned that technology has not been demonstrated to achieve no discharge of process waste water pollu tants and that it is technically impos sible. The 1977 standard is based on a plant which is only two years old. Commentors question whether existing plants can economically achieve its effluent quality. The control technology used at the exemplary plant consists of leak and spill containment and pickle liquor treatment for chromium reduction followed by sedimentation to achieve the proposed guidelines. Another plant uses conven tional sodium hydrosulfide treatment and lime to attain the proposed chromium levels. The proposed effluent limitations can bo attained in existing faciiitles.-Tlie proposed new source per formance standards were based on evaporation to attain no discharge of process waste water pollutants. Consid ering nonwater environmental aspects, the new source performance standards have been revised to require good water conservation and best practicable technology, (20) Sodium chloride. Commentors stated that most plants return unused bitterns to the source. They feel that dis charges do not threaten aquatic life or contribute to water pollution and that recovery of potassium and magnesium salts is not economical. Although some plants may have ample land to store waste bitterns, tills treat ment is not universally applicable. Alter native means to achieve no discharge of process waste water pollutants are eco nomically prohibitive. If no pollutants are added to the waste bitterns, return of the unused salts to the source is a reason able limitation for technology-based standards. (21) Sodium Silicate. Some comments stated that sodium hydroxide, sodium sulfate, and silica should not be con sidered pollutants. Because of their natu ral occurrence in most waters, costs to achieve no discharge of these compounds are not justified. They further state that recycle is. not possible because of turbidity problems and evaporation ponds are not universally applicable.

Inclusion of efflu ent limitations for suspended solids, pH, and Iron are sufficient to ensure compli ance with the effluent reduction attain able through the application of the required levels of treatment technology. Other waste water constituents appear in relatively minor quantities and are ade quately removed when the Iron limitation is achieved. The rationale presented above for using the parameter "total iron" is applicable to the sulfate process also. The process waste water flow basis of 100,000 1/kkg has been re-examined. Based on initial data and comments re ceived this basis has been revised. A total process waste water flow of 210.000 1/kkg of product is achievable using recycle of scrubber water. Detailed data have been supplied subsequent to the publica tion of the proposed regulations. These data indicate the costs to reduce tbe TSS Wco1ncentration to 25 mg/1 are greater, v.an initially estimated.

(7) The effluent limitation of sus pended solids has been revised for dia phragm cell chlorine plants, (8) The effluent limitations for titanum dioxide production have been changed to exclude limitations on trace elements. The parameter "total dissolved iron" has been amended to "total iron" and the guideline has been altered ac cordingly. (9) The effluent limitations for tita nium dioxide production by the sulfate process have been changed. The flow basis has been increased resulting in less stringent limitations on iron and sus pended solids. (10) Minor adjustments have been made to reflect the fact that an increased number of definitions and analytical methods have been included in 40 CFR 401 and are incorporated by reference where applicable. (11) Section 304(b) (1) (B) of the Act provides for "guidelines" to implement the uniform national standards of sec tion 301(b)(1)(A). Thus Congress rec ognized that some flexibility was neces sary' in order to take into account the complexity of the industrial world with respect to the practicability of pollution control technology. In conformity with the Congressional intent and in recogni tion of the possible failure of these regu lations to account for all factors bearing on the practicability of control technol ogy', It yyas concluded that some provision was needed to authorize flexibility in the strict application of the limitations con tained in the regulation where required by special circumstances applicable to individual dischargers. Accordingly, a provision allowing flexibility in the ap plication of the limitations representing best practicable control technology cur rently available has been added to each subpart, to account for special circum stances that may not have been .ade quately accounted for when these regu lations were developed. (12) An allowance lias been provided to permit the discharge of process waste water pollutants from plants located in areas where precipitation exceeds evap oration. An allowance has also been pro vided for discharge in the event of a cat astrophic rainfall. These allowances are applicable only to chemical subcategor ies which may utilize ponds to achieve no discharge of process waste water pollu tants. Economic Impact The changes that were made to the proposed regulations for the inorganic chemicals manufacturing category do not substantially affect the initial eco nomic analysis. The changes detailed above concern new sources and reflect a re-evaluation of the efficiency of vari ous treatment systems. These revisions, however, do not affect the conclusions of the economic impact study. Cost-Benefit Analysis The detrimental effects of the con stituents of waste waters now discharged by point sources within the major in organic products segment of the inor ganic chemicals manufacturing point source category are discussed in Section VT of the report entitled "Development Document for Effluent Limitations Guide lines for the major inorganic products segment of the Inorganic Chemicals Manufacturing Point Source Category" (August 1974).

It is, however, possible that data which would alfect these limitations have not been available and, as a result, these limitations should be adjusted for certain plants in this industry. An in dividual discharger or other interested person may submit evidence to the Regional Administrator (or to the State, if the State has the authority to issue NPDES permits) that factors relating to the equipment or facilities involved, the process applied, or other such factors re lated to such discharger are fundamen tally different from the factors con sidered in tile establishment of the guidelines. On tho basis of such evidence or other available information, the Regional Administrator (or the State) will make a written finding that such factors are or are not fundamentally different for that facility compared to those specified in the Development Docu ment. If such fundamentally different factors are found to exist, the Regional Administrator or the State shall establish for the discharger effluent limitations in the NPDES permit either more or less stringent than the limitations established herein, to the extent dictated by such fundamentally different factors. Such limitations must be approved by the Administrator of the Environmental Protection Agency.

The first is to declare that the guidelines do not apply. The second is to apply the guidelines unchanged. The third is to modify the guidelines to reflect: (1) differences between direct dischargers and plants utilising municipal systems which affect the practicability of the latter employing the technology available to achieve the effluent limitations guide lines: or (2) characteristics of the rele vant pollutants which require higher levels of reduction (or permit less strin gent levels) in order to insure that the pollutants do not interfere with the treatment works or pass through them untreated. The first option, which would leave the introduction of incompatible pollutants unregulated by a national pretreatment standard, is inappropriate in view of the information available to the Agency concerning the effects of those pollut ants generated by the inorganic chemi cals manufacturing category and the available treatment technologies. The Agency believes that treatment levels re quired of ^plants utilizing municipal treatment systems should be comparable to those applicable to direct discharges, so that use of such systems does not re sult in higher levels of ultimate pollut ant discharge to navigable waters or in any unjustified economic advantage. The process waste waters in the inor ganic chemicals industry generally con tain high concentrations of dissolved solids. These solids could Interfere with the operation of publicly owned treat ment works, pass through such works untreated or Inadequately treated, or otherwise bo incompatible with such treatment works. The information avail able to the Agency does not indicate dif ferences between plants which discharge directly to navigable waters and those which use municipal treatment systems significant enough to warrant varying the effluent limitation guidelines. Accord ingly, it is the opinion of the Agency that these incompatible process waste water constituents should be treated to the level required by the application of the best practicable control technology currently available before discharge of these waste water constituents to publicly owned treatment works. In those cases where the effluent limitation guidelines based on best practicable control technology currently available are not defined for an incompatible pollutant, such as dis solved solids, no pretreatment will be required for such incompatible pollut ants unless, pursuant to 40 CFR 128, Section 128.131, the wastes interfere with the operation or performance of the publicly owned treatment works, or pretreatment Is required by local or State law, as provided for in 307(b) (4) of the Act.

(h) Whenever under the normal poli cies or procedures of a bureau a hearing' would be held on a matter requiring the preparation of an environmental impact statement, the environmental aspects should be included in the hearing. In other cases the question of whether a hearing should be held with respect to an environmental matter shall be deter mined in accordance with the criteria set forth in 1500.3(d) of the Guidelines. Normally, all hearings contemplated in this paragraph should be based on a draft environmental impact statement, which should in any event be made available to the public at least 15 days before the heating. (1) If as the result of the considera tion of a proposed action as provided for by (b) above it is determined that no en vironmental Impact statement is required under section 102(2) (C) of NEPA, a suci cinct but complete negative statement describing the action, the environmental Impacts considered and the reasons why it has been concluded that an impact statement need not be filed shall be pre pared by the head of the bureau having jurisdiction over the matter or by an of ficer specifically designated by him for the purpose. The Bureau EQO shall par ticipate as appropriate in the prepara tion of such statements, which shall be submitted for thp review and approval of the Departmental EQO. A file of such negative statements, available for public Inspection, shall be maintained by the Bureau EQO (see CEQ Guidelines, { 1500.6(e)). ment of the normal time periods and related procedures, a draft statement may be furnished to the Congress and made available to the public pending transmittal of the comments as received and the final text (CEQ Guidelines, 5 1500.12(b)). (e) In the event of emergencies or overriding considerations of expense, the CEQ may be consulted, through the De partmental EQO, on possible variations of the specified periods (CEQ Guidelines, 1500.11(e)). 4. General considerations as to utiliza tion of impact statements, (a) Environtal impact statements are to be utilized with the greatest effectiveness possible in the process of assessing and reviewingLproposed departmental policies, pro grams, and projects. All bureaus should take special care in determining at what stage or stages of a series of actions relat ing to a particular matter the environ mental impact statement procedures cov ered by this directive shall be applied. As already indicated (section 2(b) above), the preparation of a requisite impact statement should be undertaken as early as possible in the bureau's proc ess of considering the respective pro posal. The normal process of the bureau for consideration and review of actions shall be followed, with such adjustment, particularly as to time periods, as may be necessary to permit ample fulfillment of the requirements of NEPA, the CEQ Guidelines, and these procedures (see CEQ Guidelines, 1500.3(a) and 1500.11(b)). (b) As Indicated in S 1500.9(a) of the and generally applicable environm radiation criteria and standards. (b) Where an environmental in statement is being filed with EP. comment, no special additional proc is required. However, proposed leglsi or regulations in areas of EPA resp bility must be referred to that agent comment, even if no environments pact statement under section 102 (i of NEPA is to be filed. 6.

Any pro cedures or instructions Issued by the Federal agency having jurisdiction with regard to such a statute should, of course, be consulted In the preparation of the combined statement. 9. Filina and distribution of environ mental impact statements, (a) Ten copies of each draft or final statement are to be filed- with CEQ (Guidelines, 5 1500.11(a)). (b) At the same time that each draft statement is filed with the Council, copies should also be sent to all pertinent entities, i.e.. Federal, state, and local agencies, and private organizations and individuals (CEQ Guidelines. 5 1500.9). (c) At the same time that each final statement is filed with the Council, copies should also be sent to all entities which made substantive comments on the draft statement, or requested a copy, so that they may be appropriately informed (CEQ Guidelines, 1 1500.10(b)). 10. Availability of environmental im pact statements to the public, (a) En vironmental impact statements, both draft and final, and any substantive comments thereon shall be made avail able to the public pursuant to the Free dom of Information Act (5 U.S.C. 552), the Department's regulations thereunder (31 CFR Part 1), and the disclosure charge, but when costs are significant, the bureau may, with the approval of the Departmental EQO, establish a fee which shall not exceed the actual cost of repro ducing the copies additional to those re quired to be sent to other governmental agencies (CEQ Guidelines, 3 1500.9(d)). (d) If the supply of copies of a state ment provided for in the preceding para graph has been exhausted, or a requestor seeks more than one copy without an ap propriate reason, attention should be di rected to the publication service of the National Technical Information Service of the Department of Commerce, which has been designated as the long-term "publisher" of environmental impact statements, and which offers for sale to the public the environmental impact statements of all Federal agencies. Orders should be placed with the Ordering De partment, National Technical Informa tion Service, U.S. Department of Com merce. Springfield, Virginia 22151. 11. Utilization of final impact state ments in decisional process, (a)- Section 102T2) (C) of NEFA requires that the final environmental impact statement shall accompany the proposal to which it relates through the agency review process. (b) In this process pertinent non-environmental factors are to be considered and balanced with those relating to the environment.
