A.
If any waters or wastes are discharged or are proposed to be discharged
to the district sewerage system or sewers tributary thereto, which
waters or wastes, in the judgment of the Director, may have a deleterious
effect upon said system or sewers, processes, equipment or receiving
waters, or may otherwise create a hazard to life or constitute a public
nuisance, or may exceed the concentration limits prescribed for "normal
sewage," the Director may:
(1)
Reject the waters or wastes;
(2)
Require pretreatment to an acceptable condition for discharge to
the sewers;
(3)
Require control over the quantities and rates of discharge; and/or
(4)
Require payment to cover the added costs of handling and treating
the waters or wastes not covered by existing charges or sewer rents.
B.
Also, certified tests of industrial wastewater may be required periodically
by the District.
The following are some of the industries which require approval by permit before discharging wastewater into public sewers: tanning, metal pickling, metal plating, galvanizing, pulp and paper making, brewing, distilling, public laundering, laundromats, soap making, glue manufacturing, meat and poultry packing, food processing, wool scouring, bleaching and dyeing, munitions manufacturing, slaughtering, dairies, dairy products, sugar refining, fat rendering, manufacture of syrups, jam or jelly, cotton textile manufacture or processing, or any industry producing wastes which may have or may create the aforesaid deleterious effect, hazards, nuisances, or added costs. The process or processes employed in the pretreatment and control, if required, of such wastewater shall in each case be satisfactory to and shall have the approval by permit of the Director as set forth under Article VII. No permit required pursuant to this section shall be arbitrarily denied.
No person shall discharge or cause to be discharged into the
district sewerage system or sewers tributary thereto, any of the following
materials, substances or wastes:
A.
Any liquids, solids or gases which by reason of their nature or quantity
are, or may be, sufficient either alone or by interaction with other
substances to cause fire or explosion or be injurious in any other
way to the POTW or to the operation of the POTW. At no time shall
two successive readings on an explosive hazard meter, at the point
of discharge into the system (or at any point in the system), be more
than 5% nor any single reading over 10% of the lower explosive limit
(LEL) of the meter. Prohibited materials include, but are not limited
to, gasoline, kerosene, chlorates, perchlorates, bromates, carbides,
hydrides, and sulfides and any other substances which are a fire hazard
or a hazard to the system.
B.
Any wastewater having a pH less than 5.0 or greater than 9.5, unless
the POTW is specifically designed to accommodate such wastewater,
or wastewater having any other corrosive property capable of causing
damage or hazard to sewers, structures, equipment or personnel.
C.
Solid or viscous substances, in quantities or of such size or state,
which may impair the hydraulic capacity, may cause maintenance difficulties,
or may interfere with the proper operation of the district sewerage
system and sewers tributary thereto, such as, but not limited to,
ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, tar,
plastics, wood, whole blood, paunch manure, feathers, hair and fleshings,
entrails, paper dishes, cups, milk containers, etc., either whole
or macerated.
D.
Any liquid or vapor having a temperature higher than 150° F.
(65° C.) or in such quantities that the temperature at the treatment
works influent exceeds 104° F. (40° C.). If, in the opinion
of the Director, lower temperatures of such wastes could harm either
the sewers, sewage treatment process, or equipment, have an adverse
effect on the receiving stream, or could otherwise endanger life,
health or property, or constitute or contribute to a nuisance, the
Director may prohibit such discharges.
E.
Waters or wastes containing substances which are not amenable to
treatment or reduction by the POTW processes employed, or are amenable
to treatment only to such a degree that the POTW effluent cannot meet
the requirements of regulatory agencies having jurisdiction over the
discharge to the receiving waters.
F.
Any wastewater containing toxic pollutants in sufficient quantity,
either singly or by interaction with other pollutants, to injure or
interfere with any wastewater treatment process, constitute a hazard
to humans or animals, create a toxic effect on the receiving waters
of the POTW, or to exceed the limitation set forth in a Categorical
Pretreatment Standard.
G.
Any substance which may cause the POTW's effluent or any other
product of the POTW, such as residues, sludges or scums, to be unsuitable
for reclamation process. In no case shall a substance discharged into
the POTW be in noncompliance with sludge use or disposal criteria,
guidelines or regulations developed under Section 405 of the Federal
Water Pollution Control Act, any criteria, guidelines or regulations
affecting sludge use or disposal development pursuant to the Solid
Waste Disposal Act, or state criteria applicable to the sludge management
method being used.
A.
No person shall discharge or cause to be discharged into the district
sewerage system or sewers tributary thereto the following described
materials, substances, waters or wastes if it appears likely, in the
judgment of the Director, that such wastes may have a deleterious
effect upon the district sewerage system or sewers tributary thereto,
sewage treatment or other processes, equipment, or receiving waters,
or may otherwise endanger life, limb, property or constitute a public
nuisance.
B.
In forming his or her opinion as to the acceptability of wastes listed
below, the Director shall consider their impact upon velocities in
the sewers, materials of construction, POTW processes and capacity,
degree of treatability and other pertinent factors.
C.
The materials, substances, waters and wastes prohibited or restricted
are:
(1)
Any water or wastes 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°
F. and 150° F. (0° and 65° C).
(2)
Any garbage that has not been properly shredded. The installation
and operation of garbage grinders equipped with a motor greater than
3/4 horsepower shall be subject to the review and approval of the
Director. (Not more than 30% of ground garbage, on the dry basis,
shall pass a No. 40 U.S. Standard sieve.)
(3)
Any radioactive wastes or isotopes of such half-life or concentration
as may exceed limits established by the Director in compliance with
applicable Town, county, state or federal regulations.
(4)
Materials which exert or cause unusual concentration 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.
(5)
Waters or wastes which exert or cause unusual volumes of flow or
concentration constituting "slugs" as defined herein.
(6)
Any waters or wastes containing excessive discoloration, concentrations
exceeding limits which may be established by the Director to meet
the requirements of other agencies having jurisdiction over discharge
to the receiving waters.
(7)
Any noxious malodorous liquids, gases, or solids which either singly
or by interaction with other wastes are sufficient to create a public
nuisance or hazard to life or are sufficient to prevent entry into
the sewers for maintenance and repair.
(8)
Any substance which will cause the POTW to violate its SPDES permit
or the receiving water quality standards.
(9)
Any wastewater with objectionable color not removed in the treatment
process, such as, but not limited to, dye wastes and vegetable tanning
solutions.
(10)
Any waters or waste from a motor vehicle, tank truck or any
other mobile conveyance without prior written authorization by the
Director, specifying the nature, volume, manner, time and place of
discharge.
D.
When the Director determines that a user(s) is contributing to the
POTW any of the above-enumerated substances in such amounts as to
interfere with the operation of the POTW, the Director shall:
A.
No person shall discharge or cause to be discharged into the district
sewerage system or sewers tributary thereto any water or wastes containing
toxic, poisonous, or other solids, liquids or gases in sufficient
quantity, in the judgment of the Director, either singly or by interaction
with other processes, equipment, or receiving waters, to endanger
life, limb, property or to constitute a public nuisance.
B.
The following is a partial list of such prohibited or restricted
substances:
(1)

D.
Discharge concentrations shall be determined from a twenty-four-hour
composite sample collected from the building sewer at a point prior
to connection to Kingsbury Sewer District No. 1 collector sewers.
Users with multiple discharge outfalls shall not combine wastewater
streams unless approved by the District.
E.
The Director may impose lower concentrations at the point of discharge
to the public sewers where maximum concentrations at the plant influent
are exceeded.
F.
The Director may permit higher concentrations where the substances
are effectively removed by the District's POTW and do not constitute
or create the aforesaid deleterious effects, dangers or nuisance.
G.
The provisions of this article shall not apply to any municipality
discharging sewage from a municipal sewage collection system into
the Kingsbury Sewer District No. 1 Sewage System unless the municipality
is itself the user in violation.
Upon the promulgation of the Federal Categorical Pretreatment
Standards for a particular industrial subcategory, the federal standard,
if more stringent than limitations imposed under these rules and regulations
for sources in that subcategory, shall immediately supersede the limitations
imposed under these rules and regulations. The Director shall notify
all affected users of the applicable reporting requirements under
40 CFR 403.12.
State requirements and limitations on discharges shall apply
in any case where they are more stringent than federal requirements
and limitations or those in these rules and regulations.
No user shall increase the use of process or, in any way, attempt
to dilute a discharge as a partial or complete substitute for adequate
pretreatment to achieve compliance with the standards, or any pollutant-specific
limitation by the District or state.
