[Ord. of 1-13-1972, art.
IV, § 2]
(a) No person shall discharge or cause to be discharged any wastes into
a public sewer unless the acceptance of these wastes has been approved
by the Blackstone Valley Sewer Commission and the state department
of health.
(b) The acceptance of any wastes into any sewer shall be in accordance
with all rules and regulations established by the Blackstone Valley
Sewer Commission, the state department of health, and the Town public
works department.
(c) It shall be the responsibility of any industrial or commercial plant
to furnish the Town Engineer and the director of public works the
proportions of the chemical makeup of the wastes that they intend
to discharge into the public sewer. If the wastes that they plan to
discharge into a public sewer are objectionable to the Blackstone
Valley Sewer Commission, the state department of health or the Town
public works department, it shall be the applicant's responsibility
to take whatever steps required to make them suitable and acceptable
to the Blackstone Valley Sewer Commission, the state department of
health and the Town public works department. The applicant shall furnish,
if requested, samples of the waste, together with a chemical breakdown
of what they propose to discharge into the proposed public sewer.
This information is to be furnished to any of such agencies so requesting.
[Ord. of 7-8-1976(2),
art. XIV, § A]
Any person proposing a new discharge into the system or a substantial
change in the volume or character of pollutants that are being discharged
into the system shall notify the department of public works at least
45 days prior to the proposed change or connection.
[Ord. of 7-8-1976(2),
art. XIV, § B]
No person shall make connection of roof downspouts, exterior
foundation drains, arcaway drains, or other sources of surface runoff
or groundwater to a building sewer or building drain which in turn
is connected directly or indirectly to a public sanitary sewer.
[Ord. of 7-8-1976(2),
art. XII, § B]
It shall be unlawful to discharge to any natural outlet within
the Town or in any area under the jurisdiction of the Town, any sewage
or other polluted waters, except where suitable treatment has been
provided in accordance with the provisions of this article.
[Ord. of 7-8-1976(2),
art. XV, § A]
Stormwater and all other unpolluted drainage shall be discharged
to such sewers as are specifically designated as combined sewers or
storm sewers, or to a natural outlet approved by the Town Engineer.
Industrial cooling water or unpolluted process waters may be discharged,
on approval of the Town Engineer, to a storm sewer, combined sewer,
or natural outlets.
[Ord. of 7-8-1976(2),
art. XV, § B]
No person shall discharge or cause to be discharged any of the
following described waters or wastes to any public sewers:
(1) Any gasoline, benzene, naphtha, fuel oil, or other flammable or explosive
liquid, solid, or gas.
(2) Any waters or wastes containing toxic or poisonous solids, liquids,
or gases in sufficient quantity, either singly or by interaction with
other wastes, to injure or interfere with any sewage treatment process,
constitute a hazard to humans or animals, create a public nuisance,
or create any hazard in the receiving waters of the sewage treatment
plant.
(3) Any waters or wastes having a pH lower than 5.5, or having any other
corrosive property capable of causing damage or hazard to structures,
equipment, and personnel of the sewage works.
(4) Solid or viscous substances in quantities or of such size capable
of causing obstruction to the flow in sewers, or other interference
with the proper operation of the sewage works such as, but not limited
to, ashes, cinders, sand, mud, straw, shavings, metal, glass, rags,
feathers, tar, plastics, wood, unground garbage, whole blood, paunch
manure, hair and fleshings, entrails and paper dishes, cups, milk
containers, etc., either whole or ground by garbage grinders.
[Ord. of 7-8-1976(2),
art. XV, § C]
No person shall discharge or cause to be discharged the following
described substances, materials, waters, or wastes if it appears likely
in the opinion of the Town Engineer that such wastes can harm either
the sewers, sewage treatment process, or equipment, have an adverse
effect on the receiving stream, or can otherwise endanger life, limb,
public property or constitute a nuisance. In forming his opinion as
to the acceptability of these wastes, the Town Engineer will give
consideration to such factors as the quantities of subject wastes
in relation to flows and velocities in the sewers, materials of construction
of the sewers, nature of the sewage treatment process, capacity of
the sewage treatment plant, degree of treatability of wastes in the
sewage treatment plant, and other pertinent factors. The substances
prohibited are:
(1) Any liquid or vapor having a temperature higher than 150° F.
(65° C.).
(2) Any water or waste containing fats, wax, grease, or oils, whether
emulsified or not, in excess of 100 mg/l or containing substances
which may solidify or become viscous at temperatures between 32 and
150° F. (0 and 65° C.).
(3) Any garbage that has not been properly shredded. The installation
and operation of any garbage grinder equipped with a motor of three-quarter
horsepower or greater shall be subject to the review and approval
of the Town Engineer.
(4) Any waters or wastes containing strong acid iron pickling wastes,
or concentrated plating solutions whether neutralized or not.
(5) Any waters or wastes containing iron, chromium, copper, zinc, and
similar objectionable or toxic substances; or wastes exerting an excessive
chlorine requirement, to such degree that any such material received
in the composite sewage at the sewage treatment works exceeds the
limits established by the Town Engineer for such materials.
(6) Any waters or wastes containing phenols or other taste or odor producing
substances, in such concentrations exceeding limits which may be established
by the Town Engineer as necessary, after treatment of the composite
sewage, to meet the requirements of the state, federal or other public
agencies of jurisdiction for such discharge to the receiving waters.
(7) Any radioactive wastes or isotopes of such half-life or concentration
as may exceed limits established by the Town Engineer in compliance
with applicable state or federal regulations.
(8) Any waters or wastes having a pH in excess of 9.5.
(9) Materials which exert or cause:
a. Unusual concentrations of inert suspended solids such as, but not
limited to, fuller's earth, lime slurries, and lime residues or of
dissolved solids such as, but not limited to, sodium chloride and
sodium sulfate.
b. Excessive discoloration such as, but not limited to, dye wastes and
vegetable tanning solutions.
c. Unusual BOD, chemical oxygen demand, or chlorine requirements in
such quantities as to constitute a significant load on the sewage
treatment works.
d. Unusual volume of flow or concentration of wastes constituting slugs.
(10)
Waters or wastes containing substances which are not amenable
to treatment or reduction by the sewage treatment processes employed,
or are amenable to treatment only to such degree that the sewage treatment
plant effluent cannot meet the requirements of other agencies having
jurisdiction over discharge to the receiving waters.
[Ord. of 7-8-1976(2),
art. XV, § H]
All industries discharging into a public sewer shall perform
such monitoring of their discharge as the department of public works
and 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
department of public works. Such records shall be made available upon
request by the department of public works to other agencies having
jurisdiction over discharges to the receiving water.
[Ord. of 7-8-1976(2),
art. XV, § I]
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 therefore, by the industrial concern.
