(A) Submission of data on industrial wastes. Any person who discharges industrial wastes into the town's sewerage system, either directly or indirectly, shall, upon the written request of the Board of Trustees, fill out and file with the town within 90 days an industrial waste questionnaire to be furnished by the town, in which he shall set out the quantity and characteristics of the wastes discharged into the town's sewerage system. Similarly, any person desiring to establish a new connection to a public sewer for the purpose of discharging industrial wastes shall be required to fill out and file such a questionnaire, which shall include actual or predicted data relating to the quantity and characteristics of the wastes to be discharged. When special circumstances such as the size or complexity of his sewage disposal problem would make complying with the time schedule cited above an unreasonable burden on the person, an extension of time, not to exceed 90 days, may be granted by the Board of Trustees upon presentation of a proper application.
(B) Control manholes. Any person discharging industrial wastes into a public sewer, either directly or indirectly, may be required by the Board of Trustees, upon the recommendation of the Superintendent, to construct and maintain at his own expense 1 or more control manholes at a specified location or locations to facilitate the observation, measurement and sampling of his wastes. Such manholes shall be constructed in accordance with the standards and specifications of the town. The Board may also require the person to install and maintain in any such manhole at said 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 Trustees, upon the recommendation of the Superintendent or the Sewer Engineer, before construction is begun.
(C) Waste sampling.
(1) Any industrial wastes discharged into the public sewers shall be subject to periodic inspection and determination of character and concentration. The examination shall be made as often as the Superintendent deems it necessary (but at least once a year) and may include the use of suitable continuously monitoring instruments in appropriate cases. Samples shall be collected either manually or by overall composition of the wastes. Sampling period shall be for a period of 7 consecutive days, but may be of longer duration at the discretion of the town. In periods when the sampling program extends for a greater number of consecutive days than 7, the town shall have the prerogative of selecting the 7 consecutive days of its choice. Every care shall be exercised in collecting the samples to ensure their preservation, until analyzed, in a state comparable to that at the time the samples were collected.
(2) The installation, operation and maintenance of the sampling facilities shall be the responsibility of the person discharging the wastes and shall be subject to the approval of the Board of Trustees. Access to sampling facilities shall be granted at all times to the Superintendent or his duly authorized representative.
(D) Waste analyses. Laboratory procedures used in the examination of industrial wastes shall be those set forth in Standard Methods. However, alternative methods for certain analyses of industrial wastes may be used subject to mutual agreement between the Superintendent and the customer. The town shall make, without charge to the customer, the initial analysis and regular periodic check analyses of the customer's wastes as well as other tests the Superintendent may deem advisable. Analyses made by the town at the request of the customer shall be charged to the customer according to the 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 customer's wastes has been obtained, the town shall, for the purpose of this subchapter, make a determination of the character and concentration of the customer's wastes by using data based on analyses of similar processes or data for his type of business that are available from the U.S. Environmental Protection Agency or from 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.
(F) 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.
