(A) Submission of basic data.
(1) The approving authority may require each person who discharges or seeks to discharge industrial wastes to a public sewer to prepare and file with the approving authority, at times as it determines, a report that shall include pertinent data relating to the quantity and characteristics of the wastes discharged to the wastewater collection and treatment facilities.
(2) In the case of a new connection, the approving authority may require that this report be prepared prior to making the connection to the public sewers.
(B) Industrial discharges. If any waters or wastes are discharged or are proposed to be discharged to the public sewers, which waters or wastes contain substances or possess the characteristics enumerated herein, and which in the judgment of the approving authority have a deleterious effect upon the wastewater collection and treatment facilities, processes, equipment or receiving waters and/or soil, vegetation and groundwater, or which otherwise create a hazard to life, health or constitute a public nuisance, the approving authority may:
(1) Reject the wastes;
(2) Require pretreatment to an acceptable condition for discharge to the public sewers, pursuant to § 307(b) of the Clean Water Act, being 33 U.S.C. § 1317(b), and its amendments,
(3) Require control over the quantities and rates of discharge, and/or
(4) Require payment to cover the added cost of handling and treating the wastes not covered by existing taxes or sewer charges under the provisions of this subchapter.
(C) Control manholes.
(1) Each person discharging industrial wastes into a public sewer shall, at the discretion of the approving authority, construct and maintain 1 or more control manholes or access points to facilitation observation, measurement and sampling of wastes, including sanitary sewage.
(2) Control manholes or access facilities shall be located and built in a manner acceptable to the approving authority. If measuring and/or sampling devices are to be permanently installed, they shall be of a type acceptable to the approving authority.
(3) Control manholes, access facilities and related equipment shall be installed by the person discharging the waste, at the person's expense, and shall be maintained by the person so as to be in safe condition, accessible and in proper operating condition at all times.
(4) Plans for installation of the control manholes or access facilities and related equipment shall be approved by the approving authority prior to the beginning of construction.
(D) Measurement of flow. The volume of flow used for computing sewer service charges shall be the metered water consumption of the person shown in the records of meter readings maintained by the Water Department or utility except as noted in division (F) below.
(E) Metering of waste.
(1) Devices for measuring the volume of waste discharged may be required by the approving authority if this volume cannot otherwise be determined from the metered water consumption records.
(2) Metering devices for determining the volume of waste shall be installed, owned and maintained by the person discharging the wastewater. Following approval and installation, these meters may not be removed without the consent of the approving authority.
(F) Waste sampling.
(1) Industrial wastes discharged into the public sewers shall be subject to the periodic inspection and determination of character and concentration of those wastes. The determination shall be made by the industry as often as may be deemed necessary by the approving authority.
(2) Samples shall be collected in a manner so as to be representative of the composition of the wastes. The sampling may be accomplished either manually or by the use of mechanical equipment acceptable to the approving authority.
(3) Installation, operation and maintenance of the sampling facilities shall be the responsibility of the person discharging the waste and shall be subject to the approval of the approving authority.
(4) Access to sampling locations shall be granted to the approving authority or its duly authorized representative at all times.
(5) Every care shall be exercised in the collection of samples to ensure their preservation in a state comparable to that at the time the sample was taken.
(G) Pretreatment.
(1) Persons discharging industrial wastes into any public sewer may be required to pretreat those wastes, if the approving authority determines pretreatment is necessary to protect the wastewater collection and treatment facilities or prevent the discharge of incompatible pollutants.
(2) In that event the person shall provide at his or her expense the pretreatment or processing facilities as may be determined necessary to render wastes acceptable for admission to the sanitary sewers.
(3) No user shall increase the process water, or in any manner, attempt to dilute a discharge as a partial or complete substitute to adequate treatment to achieve compliance with limitations contained in this subchapter, or contained in the National Categorical Pretreatment Standards or any state requirements.
(H) Grease, oil and sand interceptors.
(1) Grease, oil and sand interceptors shall be provided when, in the opinion of the approving authority, they are necessary for the proper handling of liquid wastes containing floatable grease in amounts in excess of those specified in this subchapter, or any flammable wastes, sand or other harmful ingredients; except that these interceptors shall not be required for private living quarters or dwelling units.
(2) All interceptors shall be of a type and capacity approved by the approving authority, and shall be located as to be readily and easily accessible for cleaning and inspection. In maintaining these interceptors, the owner(s) shall be responsible for the proper removal and disposal by appropriate means of the captured material and shall maintain records of the dates and means of disposal which are subject to review by the approving authority.
(3) Disposal of the collected materials performed by owners(s’) personnel or currently licensed waste disposal firms must be in accordance with currently acceptable local, county and state rules and regulations.
(I) Analyses.
(1) All measurements, tests and analyses of the characteristics of waters and wastes to which reference is made in this subchapter shall be determined in accordance with the latest edition of Standard Methods and with the federal regulations of 40 C.F.R. pt. 136 Guidelines Establishing Test Procedures for Analysis of Pollutants, as amended from time to time.
(2) Sampling method, location, time, durations and frequencies are to be determined on an individual basis subject to approval by the approving authority.
(J) Submission of information. Plans, specifications and any other pertinent information relating to proposed flow alkalization pretreatment, or grease and/or sand interceptor facilities shall be submitted for review and approval of the approving authority prior to the start of their construction if the effluent from the facilities is to be discharged into the public sewers. No construction of the facilities shall commence until the approval had been granted.
