(a) Submission of Basic Data. Within sixty days after passage of this chapter, each person whose operation entails the discharge of industrial wastewater to a public sewer shall prepare and file with the City a written statement setting forth the nature of the operation contemplated or presently carried on, the amount and source of water required for use, the proposed point of discharge of such wastewater into the wastewater collection system of the City, the estimated amount to be so discharged and a fair statement setting forth the expected bacterial, physical, chemical and other known characteristics of such wastewater. Within a reasonable time of receipt of such statement, it shall be the duty of the City to make an order stating such minimum restrictions as in the judgment of the Director may be necessary to adequately guard against unlawful uses of the City’s wastewater system. If such a statement has been previously filed with the City to the satisfaction of the Director, the requirements of this section will be waived.
(b) Extension of Time. When it can be demonstrated that circumstances exist which would create an unreasonable burden on the person to comply with the time schedule imposed by subsection (a) hereof, a request for extension of time may be presented for the consideration of the Director. All requests for extension of time shall be submitted in writing stating the reasons for such a request. Under no circumstances shall the extension of time exceed thirty days after approval of the extension by the Director.
(c) Control Manholes.
(1) Each person discharging industrial wastewater into a public sewer shall construct and maintain one or more control manholes or access points to facilitate observation, measurement and sampling of his wastewater, including sanitary wastewater.
(2) Control manholes or access facilities shall be located and built in a manner acceptable to the Director. If measuring devices are to be permanently installed they shall be of a type acceptable to the Director.
(3) Control manholes, access facilities, and related equipment shall be installed by the person discharging the wastewater at his expense, and shall be maintained by him so as to be in safe condition, accessible and in proper operating condition at all times. Plans for the installation of such facilities shall be approved by the Director prior to the beginning of construction.
(4) In the event no special manhole has been required, the control manhole may be considered to be the nearest downstream manhole in the public sewer to the point at which the Building Sewer is connected.
(d) Wastewater Volume Determination.
(1) The volume of flow used for computing industrial wastewater charges shall be the metered water consumption of the industrial user as shown in the records of water meter readings maintained by the City, except as herein provided.
(2) If the person discharging industrial wastewater into the public sewers procures any part, or all, of this water from sources other than the City water system, all or part of which is discharged into the public sewers, the person shall install and maintain at his expense water meters of a type approved by the Director for the purpose of determining the volume of water obtained from those other sources.
(3) The person discharging industrial wastewater into the public sewers may install and maintain at his expense metering devices for determining the volume of wastewater being discharged to the public sewer, from which the industrial wastewater charges would be computed. The measuring devices shall be of a type acceptable to the Director.
(4) The Director may require the installation of devices for measuring the volume of wastewater discharged if these volumes cannot otherwise be determined from the metered water consumption records.
(5) Any metering device for determining the volume of wastewater discharged to the public sewer shall be installed, owned and maintained by the industrial user. Following approval and installation, such meters may not be removed without the consent of the Director.
(e) Sampling and Monitoring.
(1) Industrial wastewaters discharged into the public sewers shall be subject to periodic inspection with a determination of character and concentration of such wastes. The determination shall be made as often as may be deemed necessary by the Director but in no case less than one twenty-four hour composite sample per quarter. The owner shall be responsible for the collection and testing of the aforementioned samples.
(2) Samples shall be collected in such a manner as to be representative of the composition of the wastewater. The sampling shall be accomplished by the use of automatic sampling equipment capable of collecting composite samples, or by other approved means.
(3) Access to sampling locations shall be granted to the Director or his authorized representative at all times. Care shall be exercised in the collection of samples to insure their preservation in a state comparable to that at the time the sample was taken.
(f) Analysis.
(1) Laboratory procedure used in the examination of industrial wastewaters shall be those set forth in the latest edition of "Standard Methods" or "EPA Methods". However, alternative methods for certain analyses of industrial wastewaters may be used subject to mutual agreement between the Director and the industrial user. Reference is made to EPA "Guidelines Establishing Test Procedures for Analysis of Pollutants" (40 CFR 136).
(2) Determination of the character and concentration of the industrial wastewaters shall be made by the industrial user responsible for the discharge, or the industrial user's qualified agent as approved by the Director. The results of the analyses shall be reported to the City on a quarterly basis on forms provided by the City. The City may make its own analyses on the wastewaters and these determinations, when made, shall be binding as a basis for charges, except under circumstances in the subsection (f)(3) hereof.
(3) In case the analyses performed by the industry and the City result in substantially different values, an effort shall be made by the industry to collect samples at the same time the City collects its own samples. The results of the analyses on the samples collected by the City and the industry shall be compared using the same testing procedures as outlined in the latest edition of "Standard Methods" and the differences negotiated.
