A.
No person(s) shall discharge or cause to be discharged any unpolluted
waters such as stormwater, groundwater, roof runoff, subsurface drainage
or cooling water to any sewer.
B.
Stormwater and all other unpolluted drainage shall be discharged
to storm sewers or to a natural outlet approved by the Town and other
regulatory agencies. Unpolluted industrial cooling water or process
waters require a National Pollutant Discharge Elimination System (NPDES)
Permit, approval of the Town, and approval of other regulatory agencies
prior to discharge to a storm sewer or natural outlet.
C.
No person(s) shall discharge or cause to be discharged any of the
following described waters or wastes to any public sewers:
(1)
Any gasoline, benzene, naptha, fuel oil, or other flammable or explosive
liquid, solid, or gas.
(2)
Any waters containing toxic or poisonous solids, liquids, or gases
in sufficient quantity, either singly or by interaction with other
wastes, to injure, interfere with or pass through any waste treatment
process, constitute a hazard to humans or animals, create a public
nuisance or create any hazard in the receiving water of the wastewater
treatment plant, including but not limited to cyanides, heavy metals,
strong acids, basic waste, etc. Other hazardous, toxic, or reactive
pollutants, including but not limited to halogenated hydrocarbons,
organic solvents, and organochlorine insecticides, are also prohibited
from the municipal sewer system.
(3)
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 wastewater facilities, such as, but
not limited to, ashes, bones, cinders, sand, mud, straw, shavings,
metal, glass, rags, feathers, tar, plastic, wood, unground garbage,
whole blood, paunch manure, hair and containers, etc., either whole
or ground by garbage grinders.
(4)
Strong acid pickling waste and concentrated plating solutions, whether
neutralized or not.
The following described substances, materials, waters, or wastes
shall be limited in discharge to the municipal sewerage system to
concentrations or quantities which will not harm either the sewers,
wastewater treatment processes or equipment, will not have an adverse
effect on the receiving stream, and will not otherwise endanger life,
limb, or public property or constitute a nuisance. The Board of Selectmen
may set more restrictive limitations that those established herein
to meet the above objectives. In forming an opinion as to acceptability,
the Board of Selectmen will give consideration to such factors as
the quantity of subject waste in relation to flows and velocities
in the sewers, materials of construction of the sewers, the wastewater
treatment processes employed, capacity of the wastewater treatment
plant, and other pertinent factors. The limitations or restrictions
on materials or characteristics of waste or wastewaters discharged
to the sanitary sewer which shall not be violated without approval
of the Board of Selectmen include but are not limited to the following:
A.
Wastewater sufficiently hot to cause the influent at the wastewater
treatment facilities to exceed 104° F. (40° C.).
B.
Wastewater containing more than 25 milligrams per liter of petroleum
oil, nonbiodegradeable cutting oils, or product of mineral oil origin.
C.
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.
D.
Any garbage that has not been properly shredded (see the definition of "properly shredded garbage" in § 398-1). Garbage grinders may be connected to sanitary sewers from homes, hotels, institutions, restaurants, hospitals, catering establishments, or similar places where garbage originates from the preparation of food in kitchens for the purpose of consumption on the premises or when served by caterers.
E.
Any waters or wastes containing heavy metals, solvents, and similar
objectionable or toxic substances to such degree that any such material
discharged to the public sewer exceeds the limits established by the
Board of Selectmen, the New Hampshire Department of Environmental
Services or the United States Environmental Protection Agency for
such materials.
F.
Any water or wastes containing phenols or other taste- or odor-producing
substances, in such concentrations exceeding limits which may be established
by the Board of Selectmen as necessary, after treatment of the composite
sewage, to meet the requirements of the state, federal, or other public
agencies of jurisdiction for such a discharge.
G.
Any radioactive wastes or isotopes of such half-life or concentration
as may exceed limits established by the Board of Selectmen in compliance
with applicable state or federal regulations.
H.
Materials which exert or cause:

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).
(2)
Excessive discoloration and dyes which cannot be removed by the treatment
facility.
(3)
Unusual volume of flow or concentration of wastes constituting slug discharges. Any unusual concentrations, spills, or slugs (see the definition of "slug" in § 398-1) shall be reported immediately to the Director of Public Works. A written report shall be sent by the user to the Board of Selectmen within five days of the incident describing the reason for the spill and remedial action taken and the steps taken to prevent its recurrence.
I.
Waters or wastes containing substances which are not amenable to
treatment or reduction by the wastewater treatment processes employed,
or are amenable to treatment only to such a degree that the wastewater
treatment plant effluent cannot meet the requirements of other agencies
having jurisdiction over discharge to the receiving waters.
J.
Any waters or wastes which, by interaction with other water or wastes
in the public sewer system, release obnoxious gases, form suspended

A.
If any waters or wastes are discharged or are proposed to be discharged to the public sewers, which waters or wastes contain the substances or possess the characteristics enumerated in § 398-6 of this article, or which in the judgment of the Town may have a deleterious effect upon the wastewater facilities, processes, equipment, or receiving waters, or which otherwise create a hazard to life or constitute a public nuisance, the Town may:
B.
If the Board of Selectmen or federal effluent limitations require
pretreatment of waste flows, the design and installation of such facilities
shall be subject to the review and approval of the Board of Selectmen
and the New Hampshire Department of Environmental Services. Such facilities
shall not be connected until said approval is obtained in writing.
Plans and specifications for proposed pretreatment facilities shall
be the result of the design of a professional engineer registered
in New Hampshire. Such approval shall not relieve the owner of the
responsibility of discharging treated wastes meeting the requirements
of this chapter.
C.
To determine compliance with user discharge permits with respect
to prohibited discharges and categorical limitations on wastewater
discharges, prohibitions and limitations may be made on the basis
of either instantaneous grab samples or composite samples of the wastewater.
Sampling of industrial wastewaters for the purpose of compliance determination
will be performed at such frequency as the Town designates and may
be on either a scheduled or random basis to ensure compliance.
A.
Grease, oil, and sand interceptors shall be provided when, in the opinion of the Town, they are necessary for the proper handling of liquid wastes containing floatable oil or grease in excessive amounts as specified in § 398-6 of this article 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 as to be readily and easily accessible for cleaning and inspection. Grease and oil interceptors shall be constructed of impervious material capable of withstanding abrupt and extreme changes in temperature; they shall be of substantial construction, watertight, and equipped with easily removable covers which, when bolted in place, shall be gastight and watertight.
B.
In the maintaining of these interceptors the owner(s) shall be responsible
for the proper removal and disposal by appropriate means of the captured
material and shall maintain records of the dates and means of disposal
which are subject to review by the Town. Any removal and hauling of
the collected materials not performed by the owner's personnel must
be performed by currently licensed waste disposal firms.
All industrial waste shall be pretreated in accordance with
federal and state regulations and this chapter to the extent required
by applicable National Categorical Pretreatment Standards, state pretreatment
standards or standards established by the Board of Selectmen, whichever
are more stringent. Where pretreatment or flow-equalizing facilities
are provided or required for any waters or wastes, they shall be maintained
continuously in satisfactory and effective operation by and at the
expense of the owner(s).
The Town shall determine the quantity and quality of all industrial
wastes which can be properly taken into the sewerage system in addition
to the sanitary sewage from the Town, and the Town may regulate the
flow of industrial wastes into the sewerage system by separate industrial
user agreement(s) approved by the Board of Selectmen.
A.
When required by the Town, the owner(s) of any property serviced
by a building sewer carrying industrial wastes shall install a suitable
structure together with such necessary meters and other appurtenances
in the building sewer to facilitate observation, sampling, and measurement
of the wastes. Such structures, when required, shall be accessible
and safely located and shall be constructed in accordance with plans
approved by the Town. The structure shall be installed by and at the
expense of the owner(s) and shall be maintained by the owner(s) so
as to be safe and accessible at all times.
B.
All industries discharging into a public sewer shall perform such
monitoring as the Department of Public Works or duly authorized employees
or agents 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 waters.
All measurements, tests, and analyses of the characteristics
of waters and wastes to which reference is made in this chapter shall
be determined in accordance with the latest edition of Standard Methods
for Examination of Water and Wastewater, published by the American
Public Health Association, or with the EPA-approved methods published
in the Code of Federal Regulations, Title 40, Part 136 (40 CFR 136).
Sampling methods, locations, times, durations, and frequencies are
to be determined on an individual basis subject to approval by the
Board of Selectmen.
No statement contained in this article shall be constructed
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, provided that such
agreements do not contravene any requirements of existing federal
or state laws, and/or regulations promulgated thereunder, are compatible
with any user charge system in effect, and do not waive applicable
National Categorical Pretreatment Standards.
A.
Each industrial user shall be required to submit to the Town a semiannual
report on the first of May and November of each year, or such other
time as designated by the Town, containing information as to the minimum,
average and peak flows of industrial wastewater discharges during
the previous year and, at a time or times designated, analyses and
wastewater samplings taken in an acceptable manner at approved times
during the flow measuring periods.
B.
When required by the permit, each industrial permittee shall submit
a duly signed report to the Town containing all information required
by the Town. This report shall include, if appropriate, schedules
for industrial compliance with applicable pretreatment regulations,
including but not limited to implementation schedules for installation
of pretreatment facilities. If insufficient data has been furnished,
additional information may be required.
Neither domestic septic tank waste (septage) nor industrial
septic tank waste (industrial septage) will be accepted into the Salem
waste collection system. Septage and industrial septage may be discharged
at the GLSD treatment facility in North Andover, Massachusetts, subject
to prior approval by and specific regulations of the GLSD. Holding
tank wastes may be accepted into the Salem collection system provided
that such wastes do not contain toxic pollutants or materials and
provided that such discharge does not result in violation of this
chapter or other agreements entered into by the Town. Fees for dumping
holding tank wastes will be established as part of the user charge
system. Authorized Town employees, acting on behalf of the Town and
its Department of Public Works, shall have authority to limit the
disposal of such wastes, if such disposal would interfere with proper
operation of collection and disposal facilities. Procedures for the
disposal of such wastes shall be in conformance with the operating
policy of the Town's Public Works Department, and disposal shall be
accomplished under its supervision unless specifically permitted otherwise.
Permits for discharge of holding tank wastes shall be under the jurisdiction
of the Department of Public Works and subject to prior review and
approval by the GLSD. Such review by GLSD shall be made on the basis
of this chapter. It shall be illegal to meet requirements of this
chapter by diluting wastes in lieu of proper pretreatment.
