§ 53.066 CONTROL OF ACCEPTABLE WASTES.
   (A)   Submission of data on industrial wastes.
      (1)   Any person (discharger) who discharges industrial wastes into the town’s wastewater treatment system, either directly or indirectly, shall, within 30 days of a written request of the Superintendent, fill out and file with the town an industrial waste questionnaire, to be furnished by the town, in which he or she shall set out the quantity and characteristics of the wastes discharged into the town wastewater treatment system. Each discharger requested to file an industrial waste questionnaire shall be financially responsible for the sampling and analyses which may be required to determine the characteristics of the discharger’s discharge.
      (2)   Similarly, any person desiring to establish a new connection to the public sewer for the purpose of discharging industrial wastes shall be required to fill out and file such a questionnaire, which shall include the actual or predicted date relating to the quantity and characteristics of the wastes to be discharged. When special circumstances, such as the size or complexity of his or her sewage disposal problem, would make complying with the time schedule cited in this chapter an unreasonable burden on the person, an extension of time not to exceed 90 days may be granted by the Superintendent upon presentation of a proper written application.
   (B)   Control manholes. Any person discharging industrial wastes into a public sewer, either directly or indirectly, may be required by the Superintendent to construct and maintain, at his or her own expense, one or more control manholes at a specified location or locations to facilitate the observation, measurement and sampling of his or her wastes. Such manholes shall be constructed in accordance with the standards and specifications of the town. The Superintendent may also require the person to install and maintain in any such manhole, at said person’s expense, an approved volume-measuring device. The Authority must approve plans for the installation of the control manhole and related equipment before construction begins.
   (C)   Waste sampling and sampling equipment.
      (1)   Any industrial wastes discharged into the public sewers shall be subject to sampling and determination of its characteristics. The sampling and analysis shall be made as often as the Superintendent deems necessary and may include the use of suitable continuously monitoring instruments in appropriate cases. The Superintendent must approve the sampling location(s). National categorical pretreatment standards are required to be met at the point of discharge from the industrial pretreatment system prior to mixing with any other waste stream.
      (2)   Except as indicated, the user must collect wastewater samples using flow-proportional composite collection techniques. In the event flow-proportional sampling is not feasible, the Superintendent may authorize the use of time-proportional sampling or a minimum of four grab samples where the use demonstrates that this will provide a representative sample of the effluent being discharged. In addition, grab samples may be required to show compliance with instantaneous discharge limits. Samples for oil and grease, temperature, pH, cyanide, phenols, sulfides and volatile organic compounds must be obtained using grab-collection techniques.
   (D)   Waste analysis. Laboratory procedures used in the examination of industrial wastewater shall be those set forth in 40 C.F.R. part 136, “Guidelines Establishing Test Procedures for the Analysis of Pollutants,” or amendments thereto, or if 40 C.F.R. part 136 does not contain sampling analytical techniques for the pollutant in question, then in accordance with procedures approved by the EPA. The POTW may make the initial analysis and perform periodic check analyses of the customer’s wastes as well as other tests the Superintendent may deem advisable. Analyses made by the POTW at the request of the discharger shall be charged to the customer according to the POTW’s standard work order billing practices. All such analyses shall be binding in determining strength-of-wastes surcharges and other matters dependent upon the character and concentration of wastes.
   (E)   Use of representative analyses. Until an adequate analysis of a representative sample of the customer’s wastes has been obtained, the town may, for the purpose of this chapter, make a determination of character and concentration of his or her wastes by using data based on analyses of similar processes or data for his or her type of business that are available from the industry-recognized authoritative sources. This method, if selected by the town, shall continue at the town’s pleasure or until an adequate analysis has been made.
