(A) Waste sampling.
(1) Any industrial waste 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 twice a year) and may include the use of suitable continuously-monitoring instruments in appropriate cases. Samples shall be collected either manually or by approved mechanical devices and in such a manner as to be representative of the overall composition of the wastes. Sampling period shall be determined by the Superintendent. 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 town. Access to the sampling facilities shall be granted at all times to the Town Superintendent or his or her duly authorized representative.
(B) Waste analyses.
(1) Laboratory procedures used in the examination of industrial waste shall be those set forth in Standard Methods. However, alternative methods for certain analyses of industrial waste may be used subject to agreement between the Superintendent and the user.
(2) The town may make the initial analysis and any regular periodic-check analysis of the user’s waste, as well as other tests the Superintendent may deem advisable, and the cost of any analysis made by the town shall be charged to the customer according to the standard work order billing practices. All such analyses shall be binding and conclusive in determining strength of water surcharges and other matters which are dependent upon the character and concentration of wastes.
(C) Use of representative analyses. Until an adequate analysis of a representative sample of user’s wastes has been obtained, the town shall, for the purpose of this chapter, make determination of the character and concentration of the user’s wastes by using data based on analyses of similar processes or data for his or her 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 until an adequate analysis has been made.
