925.13 CONTROL OF INDUSTRIAL WASTES.
   (a)   Submission of Basic Data. Within thirty days after passage of this chapter, each person whose operation entails the discharge of industrial wastes to a public sewer shall prepare and file with the Municipality such data and items as are contained in Section 925.04(r). Within a reasonable time of receipt of such data, it shall be the duty of the Municipality to make an order stating such minimum restrictions as, in the judgment of the Superintendent, may be necessary to adequately guard against unlawful uses of the Municipality's wastewater treatment works.
 
   (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 consideration of the Superintendent. All requests for extension of time shall be submitted in writing, stating the reasons for such request. Under no circumstances shall the extension of time exceed thirty days after approval of the extension by the Superintendent.
   (c)   Control Manholes. When required by the Superintendent, an industry shall install one or more suitable structures, together with necessary meters and other appurtenances, in the building sewer(s) to facilitate observation, sampling and measurement of the wastes. Such structure(s), when required, shall be accessibly and safely located and shall be constructed in accordance with plans approved by the Superintendent. The structure(s) shall be installed by the industry at its expense and shall be maintained by the industry so as to be safe and accessible at all times.
 
   (d)   Wastewater Volume Determination. The volume of industrial wastes discharged to the wastewater treatment works of the Municipality from industries shall be determined upon the basis of the volume of wastewater discharged from the industry to the wastewater treatment works. This volume shall be the same volume as that recorded on the meter or meters used to measure from the water system of the Municipality, unless the industry is supplied with water from a source other than the water system of the Municipality and/or unless a substantial volume of water supplied to the industry is not discharged to the wastewater treatment works, in which cases, the volume of water discharged to the wastewater treatment works shall be determined by one or more meters installed to measure water flow and/or wastewater discharged, or by other means approved by the Municipality. Meters installed other than the meter or meters used to record consumption from the water system of the Municipality shall be approved by the Municipality and installed at the expense of the industry. Following approval, such meters shall not be removed without the consent of the Superintendent.
 
   (e)   Sampling and Monitoring. Industrial wastes discharged to 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 Superintendent, but in no case shall there be less than two 24-hour composite samples per month. The owner shall be responsible for the collection and testing of the aforementioned samples.
   Samples shall be collected in such a manner as to be representative of the composition of the wastes. The sampling shall be accomplished by the use of automatic sampling equipment capable of collecting composite samples. Every 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)   Analyses. Laboratory procedures used in the examination of industrial wastes shall be as provided in Section 925.11. However, alternative methods for certain analyses of industrial wastes may be used, subject to mutual agreement between the Superintendent and the owner.
   Determination of the character and concentration of the industrial wastes shall be made by the owner, or his qualified agent as approved by the Superintendent. The results of the analyses shall be reported to the Municipality on a monthly basis on forms provided by the Municipality. The Municipality shall make its own analyses on the wastes periodically. In case the analyses performed by the owner and the Municipality result in substantially different values, an effort shall be made by the owner to collect samples at the same time the Municipality collects samples. The results of the analyses on the samples collected by the Municipality and the owner shall be compared, using the same testing procedures as outlined in Section 925.11, and the differences negotiated. In the event the differences cannot be resolved, the determination performed by the Municipality shall be binding.
