Grease, oil and sand interceptors shall be provided when, in the opinion of the Board of Selectmen, they are necessary for the proper handling of liquid wastes containing grease in excessive amounts or any flammable wastes, sand or other harmful ingredients, except that such interceptors shall not be required for private living quarters or dwelling units. All interceptors shall be of a type and capacity approved by the Board of Selectmen and shall be located so as to be readily and easily accessible for cleaning and inspection.
Where preliminary treatment or flow-equalizing facilities are provided for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner at his expense.
When required by the Board of Selectmen, the owner of any property serviced by a building sewer carrying industrial wastes shall install a suitable control manhole or other sampling location, together with such necessary meters and other appurtenances, to facilitate observation, sampling and measurement of the wastes. Such manhole or other sampling location, when required, shall be accessible and safely located and shall be constructed in accordance with plans approved by the Board of Selectmen. The manhole or other sampling location, as well as meters and other appurtenances, shall be installed by the owner at his expense and shall be maintained by him/her so as to be operable and safe and accessible at all times.
All measurements, tests and analyses of the characteristics of waters and wastes to which reference is made in this chapter shall be conducted using the methods and procedures in 40 CFR Part 136. If no method is listed for a given parameter, the Director of Public Works shall specify acceptable methods.
A. 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 twenty-four-hour composite of all outfalls of a premises is appropriate or whether a grab sample or samples should be taken. Normally, but not always, BOD and suspended solids analyses are obtained from twenty-four-hour composites of all outfalls, whereas pHs must be determined from periodic grab samples).
B. All industries discharging into a public sewer shall perform such monitoring of their discharges as the Board of Selectmen and/or other duly authorized employees of the town may reasonably require, including installation, use and maintenance of monitoring equipment, keeping records and reporting the results of such monitoring to the Board of Selectmen. Such records, including records of all monitoring activities and results, whether or not such monitoring was required, shall be made available upon request for inspection and copying by the Board of Selectmen and to other agencies having jurisdiction over discharges to the receiving waters. Records shall be maintained for a minimum of three years. This period shall be extended during the course of unresolved litigation or when requested by the POTW or agency having jurisdiction over discharges to the receiving waters.
No statement contained in this article shall be construed as preventing any special agreement or arrangement between the town and any industrial concern whereby an industrial waste of unusual strength or character may be accepted by the town for treatment, subject to payment therefor by the industrial concern and subject to compliance with applicable federal and state discharge requirements.
No person shall maliciously, willfully or negligently break, damage, destroy, uncover, deface or tamper with any structure, appurtenance or equipment which is a part of the sewage works. Any person violating this provision shall be subject to immediate arrest under charge of disorderly conduct.
