(A) The Public Works Director or his or her designee shall have the authority to make whatever tests are necessary to carry out a planned sampling program and to make whatever analyses are needed for all commercial and industrial users. The BOD test shall be considered the standard test; however, COD or TOC tests may be substituted in cases where it has been determined by the Public Works Director that the BOD test is not representative of actual wastewater loading. Wastewater characteristics shall be determined by the Department on the basis of monitored wastewater discharged, a certified statement from the user, or on the best available data as to the characteristics of the discharges.
(B) Any change in the ongoing process(es) employed by a user contributing commercial or industrial waste which results in a variation of more than 25% in one or more of the effluent loading concentrations shall be reported to the Department within 30 days of the change.
(C) If it is determined through testing that a significant variation exists between the user’s certified data and the discharge characteristics monitored by the Department, the town may adjust the sewer use charge based on the monitored data from the original date of certification, unless written communication has occurred notifying the Department of changes in loading and giving specific dates of changes.
(D) Where sampling and gauging of specific users is not practical for physical, economic, safety, or other reasons, the Public Works Director may designate values for concentrations of the wastes discharged into the sewerage system for all users in the same Standard Industrial Classification or subclassification.
