§ 52.03 USE OF PUBLIC SEWERS.
   (A)   No person shall discharge or cause to be discharged to any sanitary sewer, either directly or indirectly, storm water, surface water, ground water, roof runoff, subsurface drainage, cooling water, unpolluted water or unpolluted industrial process water. The township shall require the removal of unpolluted waters from any wastewater collection or treatment facility if such removal is cost-effective and is in the best interest of all users of those facilities.
   (B)   Storm water, surface water, ground water, roof runoff, subsurface drainage, cooling water, unpolluted water or unpolluted industrial process water may be admitted to storm sewers which have adequate capacity for their accommodation. No person shall use such sewers, however, without the specific permission of the township.
   (C)   No person shall place, deposit or permit to be deposited in any unsanitary manner on public or private property within the jurisdiction of the authority, any wastewater or other polluted waters except where suitable treatment has been provided in accordance with provisions of this chapter and the NPDES permit.
   (D)   No person shall discharge or cause to be discharged to any natural outlet any wastewater or other polluted waters except where suitable treatment has been provided in accordance with provisions of this chapter.
   (E)   (1)   No person shall construct or maintain any privy, privy vault, septic tank, cesspool or other facility intended or used for the disposal of wastewater except as hereinafter provided.
      (2)   In the event any existing private sewage system shall, in the opinion of the Township Board, become a hazard to health, safety or general welfare of any persons or property, then the owner thereof shall be required, at his or her expense, to install suitable sewage facilities therein and to connect such facilities directly with the proper public sewer in accordance with the provisions of this chapter, within 90 days after date of official notice to do so.
      (3)   Where a public sanitary sewer is not available, the building sewer shall be connected to a private sewage disposal system in accordance with the specification of the County Health Department and the township.
      (4)   The owner shall operate and maintain the private sewage disposal facilities in a sanitary manner at all times, at no expense to the township.
      (5)   In the event that the owner of the property, upon which the same is located, shall fail to abandon and correct upon reasonable notice a private sewage disposal system, then and in such case, the township may do so, and charge the cost thereof to the property owner and to the occupant of the property, and such charges shall become a debt, collectible as such.
   (F)   Within six months from the time a collector sewer becomes available (within 50 feet of the property line) to any person, such person shall make connection. Such connection, however, shall be subject to the review and approval of the township and shall be contingent upon the availability of capacity in all downstream sewers, pump stations, forcemains and the sewage treatment plant including compatible pollutant capacity.
   (G)   No person shall discharge, or cause to be discharged to any public sewer, any wastes which would interfere with the operation or performance of the treatment works. Specifically, the following wastes shall not be introduced into the treatment works:
      (1)   Wastes which create a fire or explosion hazard in the treatment works;
      (2)   Wastes which will cause corrosive structural damage to treatment works, but in no case with a pH lower than 6.0;
      (3)   Any waters or wastes containing toxic or poisonous solids, liquids or gases in sufficient quantity, either singly or by interaction with other wastes to injure or interfere with any wastewater treatment process, constitute a hazard to humans or animals, create a public nuisance, or create any hazard in the receiving waters of the wastewater treatment plant, including, but not limited to, the following concentrations of materials in the wastes as received at the influent of the wastewater treatment plant; or any pollutant identified pursuant to § 307 of the Act, being 33 U.S.C. § 1317:

      (4)   Any noxious or malodorous liquids, gases or solids which either singly or by interaction with other wastes are capable of creating a public nuisance or hazard to life or are sufficient to prevent entry into the sewers for their maintenance and repair;
      (5)   Any substance which may cause the wastewater disposal systems effluent or any other product of the wastewater treatment process such as residues, sludges or scums, to be unsuitable for reclamation and reuse or to interfere with the reclamation process. In no case, shall a substance discharged to the wastewater disposal system cause the system to be in noncompliance with sludge use or disposal criteria, guidelines or regulations developed under § 405 of the Act; any criteria; guidelines or regulations affecting sludge use or disposal developed pursuant to the Solid Wastes Disposal Act, also known as Subtitle D of the Resource Conservation and Recovery Act (RCRA), being 42 U.S.C. §§ 6941 et seq., the Clean Air Act, being 42 U.S.C. §§ 7401 et seq., the Toxic Substances Control Act, being 15 U.S.C. §§ 2601 et seq., or state standards applicable to the sludge management method being used;
      (6)   Any substance which will cause the wastewater disposal system to violate its NPDES permit or the receiving water quality standards;
      (7)   Any wastewater which creates conditions at or near the wastewater disposal system which violates any statute or any rule, regulation or ordinance of any public agency or state or federal regulatory body;
      (8)   Any liquid or vapor having a temperature higher than 120°F (49°C), or causing, individually or in combination with other wastewater, the influent at the wastewater treatment plant to have a temperature exceeding 104°F (40°C);
      (9)   Any water or waste containing fats, wax, grease or oils, whether emulsified or not, in excess of 25 mg/l or containing substances which may solidify or become viscous at temperatures between 32° and 150°F (0° and 65°C);
      (10)   Any waters or wastes containing strong acid iron pickling wastes, or concentrated plating solutions whether neutralized or not;
      (11)   Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits in compliance with applicable state or federal regulations;

         (a)   Unusual concentrations of inert suspended solids (such as but not limited to, Fullers earth, lime residues) or of dissolved solids (such as, but not limited to, sodium chloride and sodium sulfate);
         (b)   Excessive discoloration (such as dye wastes and vegetative tanning solutions); and
         (c)   Unusual BOD, chemical oxygen demand or chlorine requirements in such quantities as to constitute a significant load on the wastewater treatment works.
      (14)   Solid or viscous wastes in amounts which would cause obstruction of the flow in sewers, or other interference with the proper operation of the treatment works; and
      (15)   Wastes at a flow rate and/or pollutant discharge rate (slugs) which are excessive over relatively short time periods so that there is a treatment process upset and subsequent loss of treatment efficiency.
   (H)   Treatment authority management, whenever necessary, with regard to discharge or proposed discharge of industrial wastes into any sewer, shall have the right to:
      (1)   Require new industries or industries with significant increase in discharge to submit information on wastewater characteristics and obtain prior approval for discharges;
      (2)   Reject the wastes in whole or in part for any reason deemed appropriate by the township;
      (3)   Require pretreatment of such wastes to within the limits of normal sewage as defined; and
      (4)   Require control of flow equalization of such wastes so as to avoid any “slug” loads or excessive loads that may be harmful to the treatment works.
   (I)   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, June 26, 1978, and any more stringent requirements established by the township and any subsequent federal guidelines and rules and regulations. (As specific pretreatment levels are established, they should be incorporated into this section.)
   (J)   Plans, specifications and any other pertinent information relating to pretreatment or control facilities shall be submitted for approval of the township and no construction of such facilities shall be commenced until approval in writing is granted. Where such facilities are provided, they shall be maintained continuously in satisfactory and effective operating order by the owner at his or her expense and shall be subject to periodic inspection by the township to determine that such facilities are being operated in conformance with applicable federal, state and local laws and permits. The owner shall maintain operating records and shall submit to the township a monthly summary report of the character of the influent and effluent to show the performance of the treatment facilities and for comparison against the township monitoring records.
   (K)   The township may require users of the treatment works, other than residential users, to supply pertinent information on wastewater flow characteristics. Such measurements, test and analysis shall be made at the users’ expense. If made by the township an appropriate charge may be assessed to the user as established by the township.
   (L)   The owner of any property serviced by a building sewer carrying industrial wastes or other nonresidential wastewater may be required by the township to install a control manhole together with such necessary meters and other appurtenances in the building to facilitate observation, sampling and measurement of the wastes. Such structures, when required, shall be accessible and safely located and shall be constructed in accordance with plans approved by the township. The structures shall be installed by the owner at his or her expense and shall be maintained by him or her so as to be safe and accessible at all times.
   (M)   The strength of wastewaters shall be determined, for periodic establishment of charges provided for in this chapter, from samples taken at the aforementioned structure at any period of time and of such duration and in such manner as the township may elect, or, at any place mutually agreed upon between the user and the township. Appropriate charges for sampling and analysis may be assessed to the user at the option of the township. The results of routine sampling and analysis by the user may also be used for determination.
   (N)   All measurements, tests and analysis of the characteristics of waters and wastes to which reference is made in this chapter shall be determined in accordance with latest edition of Standard Methods, except for applications for NPDES permits and reports thereof which shall be conducted in accordance with rules and regulations adopted by the U.S. Environmental Protection Agency, published in the Federal Register (40 C.F.R. part 136), and any subsequent revisions subject to approval by the township.
   (O)   (1)   Grease, oil and sand interceptors or traps shall be provided when, in the opinion of the township they are necessary for the proper handling of liquid wastes containing grease in excessive amounts, or any flammable wastes, sand and other harmful ingredients, except that such interceptors or traps will not be required for private living quarters or dwelling units.
      (2)   All interceptors or traps shall be of a type and capacity approved by the township and shall be located so as to be readily and easily accessible for cleaning and inspection. They shall be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperatures and shall be of substantial construction, to be gas-tight, water-tight and equipped with easily removable covers.
      (3)   Where installed, all grease, oil and sand interceptors or traps shall be maintained by the owner, at his or her expense, in continuously efficient operation at all times.
   (P)   Users of the treatment works shall immediately notify the township of any unusual flows or wastes that are discharged accidentally or otherwise to the sewer system.
   (Q)   No statement contained in this section shall be construed as preventing any special agreement or arrangement between the township and any industrial concern whereby an industrial waste of unusual strength or character may be accepted by the township for treatment. In all such cases the provisions set forth herein in the sewage rate regulations will be governing factors in any contracts entered into.
