(A) Wastes requiring prior approval. Review and acceptance by the Superintendent shall be obtained prior to the discharge into the public sewers by any person of sewage whose wastes have:
(1) A BOD greater than 230 mg/l;
(2) A suspended solids content greater than 230 mg/l; or
(3) Other contaminants or characteristics which, from their nature and quantity, might be harmful to the structures, processes or operations of the sewage works or to health, whether by themselves or through interacting with other wastes in the public sewers.
(B) Pretreatment facilities. When, after making the above review, the Superintendent concludes that, before the person discharges his or her wastes into the public sewers, he or she must modify or eliminate those constituents which would be harmful to the structures, processes or operations of the sewage works or injurious to health, then the person shall either modify the wastes at the point of origin or shall provide and operate at his or her own expense the preliminary treatment or processing facilities as may be determined to be necessary to render those wastes acceptable for admission to the public sewers and follow the procedures outlined in this chapter.
(C) Approval of pretreatment facilities. Plans, specifications and other pertinent information relating to proposed preliminary treatment or processing facilities shall be submitted to the city for examination and approval, and no construction of these facilities shall begin until the city, through its Board of Public Works and Safety, has given its written approval. This approval shall not exempt the person from the obligation to make further reasonable adaptations of the facilities when adaptations prove necessary to secure the results desired. Plans, specifications and other pertinent information shall also be submitted to the IDEM for approval in accordance with IDEM regulations.
(D) Operation of pretreatment facilities. When preliminary treatment facilities are provided, they shall be maintained continuously in satisfactory and effective operating condition by the person at his or her own expense and shall be subject to monthly inspection by the city. The person shall maintain suitable operating records and shall submit to the Superintendent those monthly summary reports of the character of the influent and effluent as the latter may prescribe.
(E) Grease and sand traps. Whenever the Board of Public Works and Safety determines that interceptors or traps are needed to protect the sewerage system or the operations of the wastewater treatment plant from grease, oil, sand or similar substances from occurring in a customer's sewage, then those traps shall be installed by the customer on his or her own lines at his or her own expense and shall be so maintained by the customer that none of these substances can be carried over into the public sewers. All traps shall be subject to the city's approval as to construction, location and installation.
(F) Data submission and permit requirements. The procedures authorized in this chapter shall be followed.
(G) Control manholes. Any person discharging industrial wastes into a public sewer, either directly or indirectly, may be required by the Board of Public Works and Safety, upon the recommendation of the Superintendent, to construct and maintain at his or her own expense one or more control manholes at specified location or locations to facilitate the observation, measurement, and sampling of his or her wastes. These manholes shall be constructed in accordance with the standards and specifications of the city. The Board may also require the person to install and maintain in any manhole at the person's expense an approved volume-measuring device. Plans for the installation of control manholes and related equipment must be approved by the Board of Public Works and Safety, upon the recommendation of the Superintendent, before construction is begun.
(H) Waste sampling; right of access.
(1) The Superintendent shall have the right to enter the premises of any user, at all reasonable times, to determine whether the user is complying with all requirements of this chapter and any wastewater discharge permit or order issued hereunder. Users shall allow the Superintendent ready access to all parts of the premises for the purposes of inspection, sampling, records examination and copying, and the performance of any additional duties.
(a) Where a user has security measures in force, which require proper identification and clearance before entry into its premises, the user shall make necessary arrangements with its security guards so that, upon presentation of suitable identification, the Superintendent will be permitted to enter without delay for the purposes of performing specific responsibilities.
(b) The Superintendent shall have the right to set up on the user's property, or require installation of, devices as are necessary to conduct sampling and metering of the user's operations.
(c) The Superintendent may require the user, at the user's expense, to install monitoring equipment as necessary. The facility's sampling and monitoring equipment shall be maintained at all times in a safe and proper operating condition by the user at its own expense. All devices used to measure wastewater flow and quantity shall be calibrated at a minimum of once a year to ensure their accuracy.
(d) Any temporary or permanent obstruction to safe and easy access to the facility to be inspected or sampled shall be promptly removed by the user at the written or verbal request of the Superintendent and shall not be replaced. The costs of clearing this access shall be borne by the user.
(e) Unreasonable delays in allowing the Superintendent access to the user's premises shall be a violation of this chapter.
(2) If the Superintendent has been refused access to a building, structure or property, or any part thereof, and is able to demonstrate probable cause to believe that there may be a violation of this chapter, or that there is a need to inspect or sample as part of a routine inspection and sampling program of the city designed to verify compliance with this chapter or any permit or order issued hereunder, or to protect the overall public health, safety and welfare of the community, then the Superintendent may seek issuance of a search warrant from the Superior or Circuit Court.
(I) Laboratory procedures.
(1) Laboratory procedures used in the examination of industrial wastes shall be those set forth in Standard Methods For the Examination of Water and Wastewater, 21st Edition (list of approved biological test procedures as set forth in 40 C.F.R. § 136.3). However, alternative methods for certain analyses of industrial wastes may be used to mutual agreement between the Superintendent and the user provided they meet federal requirements as set forth in 40 C.F.R. Part 136. The city may make, without charge to the user, the initial analysis of the user's wastes as well as other initial tests the Superintendent may deem advisable. Regular periodic check analyses and analyses made by the city at the request of the user shall be charged to the user according to the standard work order billing practice.
(2) All the analyses shall be binding in determining strength-of-wastes surcharges and other matters dependent upon the character and concentration of wastes.
(J) Representative analyses.
(1) Until an adequate analysis of a representative sample of a user's wastes has been obtained, the city shall, for the purpose of this chapter, make a determination of the character and concentration of the user's wastes by using data based on analyses of similar processes or data for that type of business that are available from the U.S. Environmental Protection Agency or from industry-recognized authoritative sources.
(2) This method, if selected by the city, shall continue at the city's pleasure or until an adequate analysis has been made.
(K) EPA review. All data collected pertaining to industrial wastes, including records kept by each industrial user, shall be subject to audit and review by the Environmental Protection Agency.
