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.
