All users of the Town sewerage system shall comply with applicable
standards and requirements of the Clean Water Act and standards and
requirements promulgated pursuant to the Act, including, but not limited
to, the standards and requirements in 40 CFR Parts 406 through 471,
inclusive.
A.
General prohibitions. The direct or indirect discharge of any pollutant or wastewater into the Town sewerage system that results in pass through or interference as defined in § 155-3 is prohibited. This general prohibition applies to all users of the Town and County sewerage systems whether, or not, the user is subject to federal categorical pretreatment standards, or any other federal, state, or local pretreatment standards or requirements.
B.
Specific prohibitions. Without limiting the generality of the foregoing,
the following are specifically prohibited from being discharged to
the Town sewerage system:
(1)
Solids, liquids, 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 a fire or an explosion or be injurious, in any
way, to the Town or county sewerage system, or to the operation of
the Town or county sewage treatment plants. At no time shall both
of two successive readings on a flame type explosion hazard meter,
at the point of discharge into the system (or at any other point in
the system) be more than 25% nor any single reading be more than 40%
of the lower explosive limit (LEL) of the meter. Unless explicitly
allowable by a written permit, prohibited materials in any quantity
include, but are not limited to, gasoline, kerosene, naphtha, benzene,
toluene, xylene, ethers, alcohols, carbides, hydrides, and sulfides,
and any other substance which the Town, the county, the state, or
the USEPA has determined to be a fire or explosion hazard.
(2)
Solids or viscous substances, which may cause obstruction to the
flow in a sewer or otherwise interfere with the operation of the wastewater
treatment facilities. Unless explicitly allowable by a written permit,
such substances include, but are not limited to, grease, food wastes
with particles greater than 1/2 inch in any dimension, animal guts
or tissues, paunch manure, bones, hair, hides or fleshing, entrails,
whole blood, feathers, ashes, cinders, sand, spent lime, stone or
marble dust, metal, glass, straw, shavings, grass clippings, rags,
dental floss, spent grains, spent hops, waste paper, cleaning wipes,
baby wipes, diapers, nursing pads, sanitary napkins, tampons, maxi-pads,
wood, plastics, rubber, latex, condoms, gas, tar asphalt, residues,
residues from refining or processing fuel or lubricating oil, mud,
or glass or stone grindings or polishing wastes.
(3)
Wastewater having a pH less than 5.5 or greater than 9.5 or wastewater
having any other corrosive property capable of causing damage or hazard
to structures, equipment, or Town or county personnel.
(4)
Wastewater containing toxic pollutants in sufficient quantity, either
singly or by interaction with other pollutants (including heat), to
injure or interfere with any wastewater treatment process, to constitute
a hazard to humans or animals, to create a toxic effect in the receiving
waters for treated effluent from the Town and county wastewater treatment
plants, or to exceed the limitation set forth in a categorical pretreatment
standard. A toxic pollutant shall include, but not be limited to,
any pollutant identified pursuant to Section 307(a) of the Clean Water
Act.[1]

Editor's Note: See 33 U.S.C. § 1251 et seq.
(5)
Noxious or malodorous solids, liquids, or gases which either singly
or by interaction with other wastes are sufficient to create a public
nuisance or a hazard to life or are sufficient to prevent entry into
the sewers for their maintenance or repair.
(6)
Commercial, institutional or industrial wastes containing fats, waxes,
grease, or oils, whether emulsified or not, which exceed 100 mg/L
or which become visible solids when the wastes are cooled to 10°
C. (50° F.).
(7)
Wastewater containing petroleum oil, nonbiodegradable cutting oil,
or products of mineral oil origin, in excess of 100 mg/L or in amounts
that will cause interference or pass through.
(8)
Wastewater containing pollutants that impart objectionable color
that is not removed by wastewater treatment processes employed at
the Town and county sewage treatment plants. Such wastewater may include,
but is not limited to dye wastes and vegetable tanning solutions.
(9)
Solids, liquids, vapors, or gases having a temperature higher than
65° C. (150° F.). Any materials that cause the temperature
of the wastewater at the influent to the Town or county sewage treatment
plant to exceed 40° C. (104° F.). The Superintendent reserves
the right, in certain instances, to prohibit or limit the discharge
of wastes whose maximum temperatures are lower than 65° C.
(10)
Wastewaters flow rate or concentration of pollutants, which
constitute slugs, except by wastewater discharge permit.
(11)
Wastewater containing any radioactive wastes, except as approved
by the Superintendent, and in compliance with applicable state and
federal regulations.
(12)
Wastewater which causes a hazard to human life or which creates
a public nuisance, either by itself or in combination, in any way,
with other wastes.
(13)
Wastewater with a closed cup flash point of less than 60°
C. (140° F.) using test methods specified in 40 CFR § 261.21.
(14)
Wastewater containing pollutants which result in the presence
of toxic gases, vapors or fumes within the Town or county sewerage
system in a quantity that may cause acute or chronic worker health
and safety problems.
(15)
Any waters or wastes containing strong acid iron-pickling wastes
or concentrated plating solutions, whether neutralized or not, except
by wastewater discharge permit.
(16)
Any water or wastes containing phenols or other taste- or odor-producing
substances, in such concentrations exceeding limits which may be established
by the Superintendent or Director as necessary, after treatment of
the composite sewage, to meet requirements of the state, federal or
other public agencies of jurisdiction for such discharge to the receiving
waters.
(17)
Materials which exert or cause unusual BOD, chemical oxygen
demand or chlorine requirements in such quantities as to constitute
a significant load on the sewage treatment works except by wastewater
discharge permit.
(18)
Materials which exert or cause 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.
(19)
Stormwater, surface water, groundwater, roof runoff, subsurface
drainage, uncontaminated cooling water, uncontaminated condensate
water or any unpolluted process water.
(20)
Mercury in excess of 50 ng/L as measured using EPA Method 1631.
Limitations on wastewater flow rate or concentration of pollutants
which constitute slugs contained in this chapter may be supplemented
with more stringent limitations when, in the opinion of the Superintendent:
A.
The limitations in this chapter are not sufficient to protect the
Town and County sewerage systems;
B.
The limitations in this chapter are not sufficient to enable the
Town or County to comply with applicable water quality standards or
effluent limitations specified in the SPDES discharge permits issued
for the Town and county sewage treatment plants;
C.
The sludge generated at the Town or county sewage treatment plant
will be rendered unacceptable for disposal or reuse as the Town or
county desires, as a result of discharge of wastewaters;
D.
Municipal employees or the public will be endangered; or
E.
Air pollution and/or groundwater pollution will be caused.
The Superintendent shall have the authority to require copies
of any record related to wastewater discharges to the Town sewerage
system at the owner's expense.
A.
Except where expressly authorized to do so by an applicable pretreatment
standard, no user shall increase the use of process water or, in any
other way, attempt to dilute a discharge as a partial or complete
substitute for adequate treatment to achieve compliance with a pretreatment
standard.
B.
Dilution flow shall be considered to be inflow.
A.
Grease, oil, and sand interceptors shall be provided, when, in the
opinion of the Superintendent, they are necessary for the proper handling
of wastewater containing excessive amounts of grease, flammable substances,
sand or other harmful substances: except that such interceptors shall
not be required for private living quarters or living units. All interceptors
shall be of the type and capacity approved by the Superintendent and
shall be located to be easily accessible for cleaning and inspection.
Such interceptors shall be inspected, cleaned, and repaired regularly,
as needed, by the owner, at the owner's expense.
B.
The introduction of enzymes, bacteria, surfactants, emulsifiers or
any product, natural or otherwise, into grease or oil collecting building
sewers or interceptors for the purpose of decreasing maintenance of
such systems is prohibited without written approval of the Superintendent.
In support of any application, the user shall submit all information
necessary for evaluation as directed by the Superintendent. Any user
requesting approval may be required to perform bench, pilot and/or
full-scale evaluation at a facility within the Town and provide sampling
results and wastewater discharge reports as the Superintendent deems
necessary.
Food waste grinders at or serving commercial establishments,
institutions or industries shall not discharge into the Town sewerage
system if there is a combined sewer overflow (CSO) or a sanitary sewer
overflow (SSO) on the sewer lines conveying the waste to the Town
or county sewage treatment plant.
The Superintendent may reject a user's wastewater, when
it has been determined that the wastewater contains substances or
possess characteristics that have a deleterious effect upon the Town
or county sewage treatment plants, or which constitute a public nuisance
or hazard.
