(c) Old building sewers may be used in connection with new buildings only when they are found, on examination and test by the said < Inspector, to meet all requirements of this ordinance. (f) The size, slope, alignment, materials of construction of a building sewer, and the methods to be used in excavating, placing of the pipe, jointing, testing, and backfilling the trench, shall all conform « to the requirements of the building ■ and plumbing code or other applicable rules and regulations of the Town. In the absence of code pro- < visions or in amplification thereof. 1 the materials and procedures set forth in appropriate specifications of the A.S.T.M. and W.P.C.F. Manual of Practice No. 9 shall apply. <g) Whenever possible, the building sewer shall be brought to the building at an elevation below the basement floor. In all buildings in which any building drain < is too low to permit gravity flow to the public sewer, sanitary sewage carried by such building drain shall be lifted by an approved means and discharged to the building sewer. <h) No person shall make connection of roof downspouts, exterior foundation drains, areaway drains, of other sources of surface run-off or groundwater to a building sewer or building drain which in turn is connected directly or indirectly to a public sanitary sew er (i) The connection of the building sewer into the public sewer shall conform to the requirements of the building and plumbing code or other applicable rules and regulations of the Town, or the procedures set forth in appropriate specifications of the A.S.T.M. and the W.P.C.F. Manual of Practice No. 9. All such connections shall be made gas tight and water tight. Any deviation from the prescribed procedures and materials must be approved by the Superintendent before installation. (j) The applicant for the building sewer permit shall notify the said Inspector when the building sewer is ready for inspection and connection to the public sever. The connection shall be made under the supervision of the said Inspector or his representative. (k) All excavations for building sewer installation shall be adequately guarded with barricades and lights so as to protect the pub lie from hazard. Streets, sidewalks, parkways, and other public property disturbed in the course of the work shall be restored in a manner satisfactory to the said Town. Section 5. (a) No person shall discharge or cause to be discharged any of the following described waters or wastes to any public sewers: (I) Any gasoline, benzene, naptha, fuel oil. or other flammable or explosive liquid, solid or gas. (,2) Any waters or wastes con taining toxicor poisonous volids, liquids, or gases in sufficient quantity, either singly or by interaction with other wastes, to injure or interefere with any sewage treatment process, constitute a hazard to humans or animals, create a public nuisance, or create any hazard in the receiving waters of the sewage treatment plant (3) Anv waters or wastes having a pH lower than 5.5. or having any other corrosive property capable of causing damage or hazard to structures, equipment, and personnel of the sewage works. (4: Solid or viscous substances in quantities or of such size capable of causing obstruction to the flow in sewers, or other in-

terference with the proper operation of the sewage works such as. but not limited to. ashes, cinders. sand. mud. straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, unground garbage. whole bhxxl, paunch manure. hair and fleshings, entrails, paper, dishes, cups, milk containers, etc., either whole or ground by garbage grinders. <b) No person shall discharge or cause to be discharged the following described substances, materials. waters, or wastes if it appears likely in the opinion of the Superintendent that such wastes can harm either the sewers, sewage treatment process, or equipment, have an adverse effect on the receiving stream, or can otherwise endanger life, limb, public property. or constitute a nuisance. In forming his opinion as to the acceptabily of these wastes, the Superintendent will give consideration to such factors as the quantities of subject wastes in relation to flows and velocities in the sewers, materials or construction of the sewers, nature of the sewage treatment process, capacity of the sewage treatment plant, degree of treatability of wastes in the sewage treatment plant, and other pertin ent factors. The substances prohibited are: (1) Any liquid or vapor having a temperature higher than one hundred fifty (150) degrees Fahrenheit (65) decrees C. (2) Anv water or waste containing fats, wax, grease, or oils, whether emulsified or not, in excess of one hundred (100) mg I or containing substances which may solidify or become viscous at temperatures between thirtytwo (32) and one hundred fifty (150) degrees Fahrenheit (0 and 65) degrees C. (3) Anv garbage that has not been properly shredded. The installation and operation of anv garbage grinder equipped with a motor of three-fourths (V«) horsepower (0.76 hp metric) or greater shall be subject to the review and approval of the Superintendent. (4) Any waters or wastes containing strong acid iron pickling wastes, or concentrated plating solutions whether neutralized or not. (5) Any waters or wastes containing iron, chromium, copper, zinc, and similar objectionable or toxic substances; or wastes exerting an excessive chlorine requirement. to such degree that any such material received in the composite sewage at the sewage treatment works exceeds the limits established by the Superintendent for such materials. (6) Any waters or wastes containing phenols or other taste or odor producing substances, in such concentrations exceeding limits which may be established by the Superintendent as necessary. after treatment of the composite sewage, to meet the requirements of the State. Federal, or other public agencies of jurisdiction for such discharge to the receiving waters. (7) Any radioactive wastes or isotopes of such halflife or concentration as may exceed limits established by the Superintend ent in compliance with applicable State or Federal regulations. (8) Any waters or wastes having a pH in excess of 9.5. (9) Materials which exert or cause: (i) Unusual concentrations of inert suspended solids (such as. but not limited to. Fullers earth, lime slurries, and lime residues) or of dissolved solids (such as, but not limited to. sodium chloride and sodium sulfate). (ii) Excessive discoloration (such as. but not limited to. dve wastes and vegetable tan ning solutions). (ni) Unusual BOD. chemi cal oxygen demand, or chlor me requirements in such

quantiles as to constitute a significant load on the sewage treatment works, (iv) Unusual volume of flow or concentration of w astes con- i stituting "slugs’' as defined herein. (10) Waters or wastes containing substances which are not amenable to treatment or reduction by the sewage treatment process employed, or are amenable to treatment only to such degree that the sewage treatment plant effluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters. (c) If any waters or wastes are discharged, or are proposed to be discharged, to the public sewers, which waters contain the substances or process the characteristics enumerated in Section s(h) of this article, and which in the judgement of the Superintendent may have a deleterious effect upon the sewage works, processes, equipment, or receiving waters, or which otherwise create a hazard to life or constitute a public nuisance, the Superintendent may: (1) Require new industries or industries with significant increase in discharges to submit information on wastewater characertistics and obtain prior approval for discharges. (2) Reject the wastes in whole or in part for anv reason deemed appropriate by the Tow n. (3) Require pretreatment of such wastes to within the limits of normal sewage as defined. (4) Require control or flow equalization of such wastes so as to avoid any "slug" loads or ex cessive loads that may be harmful to the treatment works, or (5) Require pay ment of a surcharge on any excessive flows or loadings discharged to the treatment works to cover the additional costs of having capacity for and treating such wastes. H the Superintendent permits the pretreatment or equalization of waste flows, the design and installation of the plant and equipment shall be subject to the review and approval of the Superintendent and subject to the requirements of all applicable codes, ordinances, and laws. (d) Where preliminary treatment or flow-equalizing facilities are provided for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner at his expense. (e) When required by the Superintendent. the ow ner of any property serviced by a building sewer carrying industrial wastes shall install a suitable control manhole together with such necessary meters an other appurtenances in the building sewer to facilitate observation. sampling, and measurement of the wastes. Such manhole. when required, shall be accessibly and safely located, and shall be constructed in accordance with plans approved by the Superintendent. The manhole shall be installed by the owner at his expense, and shall be maintained by him so as to be safe and accessible at all times. Agents of the Town, the State Water Pollution Control Agencies, and the U. S. Environ mental Protection Agency shall be permitted to enter all properties for the purpose of inspection, observation. measurement, sampling and testing. (f) All measurements, tests, and analysis of the characteristics of waters and wastes to which reference is made in this ordinance shall be determined in accordance with the latest edition of "Standard Methods of the Examination of Water and Wastewater", publish ed bv the American Public Health Association, and shall be determined at the control manhole provided. or upon suitable samples taken at said control manhole, except for applications for NPDES permits and report thereof which shall be conducted in accordance

with rules and regulations adopted bv the USEPA published in the Federal Register October 16, 1973 (38 CFR 20756) and any subsequent revisions subject to approval by the Town. In the event that no special manhole has been required, the control manhole shall be considered to be the nearest downstream manhole in the public sewer to the point at which the building sewer is connected. Sampling shall be carried out by customarily accepted methods to reflect the effect of constituents upon the sewage works and to determine the existence of hazards to life, limb, and property . (The particular analyses involved will determine whether a twenty-four (24) hour composite of all outfalls of a premise is appropriated or whether a grab sample or samples should be taken. Normally. but not always, BOD suspended solids analyses are obtained from twenty-four (24) hour composites of all outfalls whereas pH's are determined from periodic grab samples.) (g) No statement contained in this article shall be construed as preventing any special agreement or arrangement between the Town and anv industrial concern w hereby an industrial waste of unusual strength or character may be accepted by the Town for treatment, subject to payment therefore, bv the industrial concern, at such rates as are compatible with the rate ordinance. Section 6. Pretreatment of industrial wastes from major contributing industries prior to discharge to the treatment works is required and is subject to the Rules and Regulations adopted by the United States Environmental Protection Agency (USEPA) and published in the Federal Register on November 6. 1973 (40 CFR Part 182). and "Federal Guidelines Establishing Test Procedures for Analysis of Pollutants" published in the Federal Register on October 16. 19' 7 3 (40 CFR Part 136). in addition to any more stringent requirements established by the Town, and anv subsequent State or Federal Guidelines and Rules and Regulations. Section 7. Plans, specifications, and anv other pertinent information relating to pretreatment or control facilities shall be submitted for approval of the Town and no construction of such facilities shall be commenced until approval in writing, is granted.

State and local laws and permits. Ihe owner shall maintain operating records and shall submit to the Town a monthly summary report of the character of the influent and effluent to show the performance of the treatment facilities and for comparison against Town monitoring records. Section 8. Unpolluted water from air conditioners: cooling. con densing systems or swimming p<xMs. shall be discharged to a storm sewer, where it is available, or to a combined sewer approved by the Town. Where a storm sewer is not available, discharge may be to a natural outlet approved by the Town and by the State of Indiana. Where a storm sewer, combined sewer, or natural sewer is not available, such unpolluted water may be discharged to a sanitary sewer pending written approv al by the Town. Section 9. Industrial cooling water, which mav be polluted with insoluble oils or grease or suspend ed solids, shall be pretreated tor removal of pollutants and the re suitant clear water shall be dis charge in accordance with the above Section Section 10 I he Town mav re qure users of the treatment works other than residential users, to

supply pertinent information on wastewater flows characteristics. Such measurements, tests, and analysis shall be made at the user's expense. If made by the Town an appropriate charge mav be assessed to the user at the option of the Town. Section 11. The strength of wastewaters shall be determined, for periodic establishment of charges provided for in the Rate Ordinance, from samples taken at the aforementioned structure at any period of time and of such duration and in such manner as the Town may elect, or, at anv place mutually agreed upon between the user and the Town. Appropriate charges for sampling and analysis may be assessed to the user at the option of the Town. The results of routine sampling and analysis bv the user may also be used, for determination of charges after verification by the Tow n. Section 12. Grease, oil and sand interceptors or traps shall be provided when, in the opinion of the Town, they are necessarv for the proper handling of liquid wastes containing grease in excessive amounts, or any flammable w astes. sand and other harmful ingredients. except that such interceptors or traps will not be required for private living quarters or dwelling units.
