(A) Any person, who on the effective date of this chapter is discharging industrial waste into the sanitary sewerage system, shall provide reasonable access, means and facilities for the purpose of permitting the convenient observations, measurements and sampling of the industrial waste. If the access, means and facilities are not otherwise available such person shall construct and maintain an accessible and safe control manhole on the waste line or lines for that purpose.
(B) After the effective date of this chapter, any person proposing to discharge industrial wastes in quantities greater than 50,000 gpd shall provide a control manhole, which shall include a recording wastewater meter, in accordance with the requirements of the Director.
(C) All measurements, test and analyses of the characteristics of waters and wastes to which references are made in this chapter shall be determined in accordance with the latest edition of Standard Methods for the Examination of Water and Wastewater published by the American Public Health Association, and shall be determined at the control manhole provided, or upon suitable samples taken at the control manhole. In the event that no special manhole has been required, the control manhole shall be considered to be the nearest downstream manhole in the public sewer to the point at which the building sewer is connected. Sampling shall be carried out by customarily accepted methods to reflect the effect of constituents upon the sewage works and to determine the existence of hazards to life, limb and property. The particular analyses involved will determine whether a 24-hour composite of all outfalls of a premise is appropriate or whether a grab sample or samples should be taken. BOD and suspended solids analyses will be obtained from 24-hour composites of all outfalls and pHs determined from periodic grab samples, unless otherwise determined by the Director.
(D) When required by the Director, the owner of any property serviced by a building sewer carrying industrial waste shall install a suitable control manhole together with the necessary meters and other appurtenances in the building sewer to facilitate observation, sampling and measurement of the wastes. The manhole, when required, shall be accessible and safely located, and shall be constructed in accordance with plans approved by the Director. The manhole shall be installed by the discharger at his expense and shall be maintained by him or her so as to be safe and accessible at all times. The provision of a control manhole shall be mandatory for wastes receiving pretreatment or otherwise altered or regulated before discharge and for wastes which are unusually strong and thereby subject to a surcharge.
(E) No statement contained in this section shall be construed as preventing any special agreement or arrangement between the town and any industrial concern whereby an industrial waste of unusual strength; the town for treatment, subject to payment, therefor, may accept character or quantity by the industrial concern. The making of special agreements or arrangements between the town and any industrial concern shall be strictly limited to the capability of the public sewage treatment works to treat the unusual wastes without affecting the operation, maintenance or effluent quality of the facility and the special agreements or arrangements must be shown by the industry to be the most cost-effective solution to their problem and that the monetary compensation as the town may receive will satisfy the financial demands created in order to treat the wastes from both an operation and maintenance standpoint and a capital investment standpoint. Any special agreement shall be in compliance with applicable federal and state pretreatment standards.
