A.
It shall be unlawful for any person to place, deposit
or permit to be deposited in any unsanitary manner on public or private
property within the City of Lebanon (city) or in any area under the
jurisdiction of said city, any human or animal excrement, garbage
or objectionable waste.
B.
It shall be unlawful to discharge to any natural outlet
within the city, or in any area under the jurisdiction of said city,
any wastewater or other polluted waters, except where suitable treatment
has been provided in accordance with subsequent provisions of this
chapter and with state and federal laws and regulations.
C.
Sewers for intended uses only. No person shall discharge
into any public sewer of the city, or into any fixture which thereafter
discharges into any public sewer, any waste or substance other than
for which the particular sewer is intended, designed or provided.
D.
Applicable permits required. No person shall discharge
into any public sewer of the city, or into any fixture that thereafter
discharges into any public sewer, any waste or substance until all
applicable permits have been obtained.
E.
Use of sanitary sewers. Except as specifically provided
with reference to some particular sewer, sanitary sewers shall be
used only for the conveyance and disposal of domestic wastewater,
and for industrial wastes which are not objectionable as hereinafter
provided. No sanitary sewer shall be used to receive and convey or
dispose of any stormwater or surface water, subsoil drainage or unpolluted
water.
F.
Use of storm sewers. Stormwater and all other unpolluted
drainage shall be discharged to such sewers as are specifically designed
as storm sewers, or a natural outlet approved by the Director of Public
Works. Industrial cooling water, process waters or stormwater runoff
generated in areas of industrial activity (as defined in 40 CFR Part
122) require an NPDES (National Pollutant Discharge Elimination System)
permit prior to discharge to a storm sewer or natural outlet.
G.
Use designation. If the intended or designated use
of any particular sewer or drain and allowable discharge thereto is
unclear, the Director of Public Works will consider the pertinent
facts and make a determination. Said determination will be final and
binding.
H.
Except as hereinafter provided, it shall be unlawful to construct or maintain any privy, privy vault, septic tank, cesspool or other facility intended or used for the disposal of wastewater in any area where a public sewer is available, as described in Subsection I below.
I.
The owner(s) of all houses, buildings or properties used for human occupancy, employment, recreation, or other purposes, situated within the City and abutting on any street, alley or right-of-way in which there is now located or may in the future be located a public sanitary sewer of the City is hereby required at the owner(s)' expense to install suitable toilet facilities therein, and to connect such facilities directly with the proper public sewer in accordance with the provisions of this chapter, within 90 days subsequent to the date of official notice to do so, provided that said gravity public sewer is within 100 feet of the building. This requirement for connection may be waived when permitted by the Director of Public Works after consultation with the City Manager if the household is already connected to a properly functioning, state-approved septic system approved after 1985 in accordance with the provisions of RSA 147:8. See Subsection K below.
[Amended 12-4-2019 by Ord. No. 2019-14]
J.
Where a public sanitary sewer is not available under the provisions of Subsection I above, the building sewer shall be connected to a private wastewater disposal system complying with the provisions of RSA 485-A, or revisions thereto, of the state and rules, regulations, standards and procedures promulgated thereupon. The owner(s) shall operate and maintain the private wastewater disposal facilities in a sanitary manner at all times, at no expense to the city. At no time shall any quantity of industrial waste be discharged to a private, domestic wastewater disposal facility.
K.
At such time as a public sewer becomes available to a property serviced by a private wastewater disposal system, the owner shall connect to the public sewer, as provided in Subsection I above. Any septic tanks, cesspools and similar private wastewater disposal facilities shall be cleaned of sludge and filled with clean, mineral soils, and their use shall be discontinued.
L.
No statement contained in the preceding subsections
of this section shall be construed to interfere with any additional
requirements that may be imposed by the City of Lebanon.
M.
No person(s) shall maliciously, willfully or negligently
break, damage, destroy, uncover, deface or tamper with any structure,
appurtenance or equipment which is part of the Lebanon Treatment Works.

For residential and commercial services, the owner(s) or his agent shall make application on a special form furnished by the City at least 30 days prior to said service connection and in accordance with the provisions of Article XIV of t his chapter. For an establishment discharging industrial wastes, the application shall be made at least 60 days prior to said service connection. The permit application shall be supplemented by any plans, specifications or other information (including pollution prevention studies) considered pertinent in the judgment of the Director of Public Works. A permit and inspection fee in accordance with the provisions of Code of the City of Lebanon, Chapter 68, as well as any sewer development charges as enumerated by this chapter shall be paid to the City at the time the application is filed.
[Amended 12-4-2019 by Ord. No. 2019-14]
C.
A separate and independent building sewer shall be
provided for every building; except where one building stands at the
rear of another on an interior lot and no private sewer is available
or can be constructed to the rear building through an adjoining alley,
court, yard or driveway, the front building sewer may be extended
to the rear building and the whole considered as one building sewer,
but the city does not and will not assume any obligation or responsibility
for damage caused by or resulting from any such single connection
aforementioned.
D.
Existing building sewers may be used in connection
with new buildings only when they are found, on examination and test
at owner's expense, by the Director of Public Works to meet all requirements
of this chapter.
E.
The size, slope, alignment, materials of construction
of a building sewer, and the methods to be used in excavating, placing
of the pipe, jointing, testing and backfilling the trench, shall all
conform to the requirements of the building[1] and plumbing code or other applicable rules and regulations
of the city. In the absence of code provisions or in amplification
thereof, the materials and procedures set forth in appropriate specifications
of the American Society for Testing and Materials (ASTM) and Water
Environmental Federation (WEF) Manual of Practice No. FD-5 shall apply.
F.
During construction of a new sanitary sewer, the City
may construct the service connections for existing buildings to the
curb or the property line or the edge of a right-of-way. Construction
of the building sewer, including connection to the structures served,
shall be the responsibility of the owner of the improved property
to be connected; and such owner shall indemnify and save harmless
the City, its officers and agents from all loss or damage that may
result, directly or indirectly, due to the construction of a building
sewer on his premises or its connection to the service connection.
The owner shall obtain an excavation permit and comply with conditions
prior to any excavation of the City highway. The owner shall thereafter
be obligated to pay all costs and expenses of operation, repair and
maintenance, and of reconstruction, if needed, of the building sewer
and service connection. When it is deemed in the City's best interest,
the City Manager may authorize the construction of service connections
to the foundations of existing buildings at City expense. The owner
shall thereafter be obligated to pay all costs and expenses of operation,
repair and maintenance, and of reconstruction, if needed, of the building
sewer and service connection.
[Amended 12-4-2019 by Ord. No. 2019-14]
G.
Whenever possible, the building sewer shall be brought
to the building at an elevation below the basement floor. In all buildings
in which any building drain is too low to permit gravity flow to the
public sewer, sewage conveyed by such building drain shall be lifted
by an approved means and discharged to the building sewer at the owner's
expense.
H.
No person(s) shall make connection of roof downspouts,
interior or exterior foundation drains, sump pumps, areaway 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.
I.
No person shall obstruct the free flow of air through
any drain or soil pipe.
J.
The connection of the building sewer into the public
sewer shall conform to the requirements of the Lebanon Building Code[2] or other applicable rules and regulations of the city,
or the procedures set forth in appropriate specifications of the ASTM
and the WEF Manual of Practice No. FD-5. All such connections shall
be made gas-tight and watertight and verified by proper testing. Any
deviation from the prescribed procedures and materials must be approved
by the Director of Public Works before installation.
K.
The applicant for the building sewer permit shall
notify the Director of Public Works when the building sewer is ready
for inspection and connection to the public sewer. Such notice shall
be provided not less than 48 hours in advance of the time any connection
is to be made to any public sewer. The connection and testing shall
be made under the supervision of the Director of Public Works or his
or her representative. This requirement shall also apply to repairs
or alterations to building connections, drains or pipes thereto.
L.
Suitable provisions shall be made at the point of
connection for testing, which responsibility shall rest with the holder
of the sewer connection permit.
M.
No building sewer shall be covered until it has been
inspected and approved by the Department of Public Works. If any part
of building sewer is covered before being inspected and approved,
it shall be uncovered for inspection at the cost and expense of the
owner of the improved property to be connected to the public sewer.
[Amended 12-4-2019 by Ord. No. 2019-14]
N.
The Director of Public Works shall maintain a record
of all connections made to public sewers and drains under this chapter
and all repairs and alterations made to building connections or drains
connected to or discharging into public sewers and drains of the city
or intended to so discharge. All persons concerned shall assist the
Director of Public Works in securing data needed for such records.
O.
All excavations in the city highway, if any, for building sewer installation shall be permitted as required by Chapter 152, Article II, Excavations and be adequately guarded with barricades and lights so as to protect the public from hazard. Streets, sidewalks, parkways and other public property disturbed in the course of the work shall be restored in a manner satisfactory to the city at the expense of the owner.
P.
Proposed new discharges from residential or commercial sources involving loadings exceeding 50 population equivalents (5,000 gallons per day), any new industrial discharge or any alteration in either flow or waste characteristics of greater than 20% of existing industrial wastes that are being discharged into the Lebanon Treatment Works must be approved by the NHDES. Such approvals shall be obtained in accordance with § 136-39, Reports of changed conditions, of this chapter.
A.
General prohibitions. No user shall introduce or cause
to be introduced into the Lebanon Treatment Works any pollutant or
wastewater which causes pass-through or interference. These general
prohibitions apply to all users of the Lebanon Treatment Works, whether
or not they are subject to categorical pretreatment standards or any
other federal, state or local pretreatment standards or requirements.
B.
Specific prohibitions. No user shall introduce or
cause to be introduced into the Lebanon Treatment Works the following

cause to be introduced into the Lebanon Treatment Works the following
substances, pollutants or wastewater, unless specifically authorized
by the Director of Public Works in a wastewater discharge permit:
(1)
Wastewater which imparts color that may not be removed
by the treatment process, such as, but not limited to, dye wastes
and vegetable tanning solutions, which consequently may impart color
to the treatment facility's effluent, thereby violating the city's
NPDES permit.
(2)
Noxious or malodorous liquids, gases, solids or other
wastewater which, either singly or by interaction with other wastes,
are sufficient to create a public nuisance or a hazard to life, or
to prevent entry into the sewers for maintenance or repair.

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).
D.
Pollutants, substances or wastewater prohibited by
this section shall not be processed or stored in such a manner that
they could be discharged to the Lebanon Treatment Works.
A.
The categorical pretreatment standards are found at
United States Code of Federal Regulations, 40 CFR Chapter I, Subchapter
N, Parts 405-471.
B.
The EPA shall be the control authority for industrial
users subject to categorical pretreatment standards. As the control
authority, industrial users are responsible to the EPA for compliance
with categorical pretreatment standards and the requirements of 40
CFR Part 403. Categorical industrial users shall provide the city
with copies of any reports to or correspondence with the EPA relative
to compliance with the categorical pretreatment standards.
C.
The industrial user is responsible to determine the
applicability of categorical pretreatment standards. The user may
request that the EPA provide written certification on whether the
user is subject to the requirements of a particular category.
[Amended 12-4-2019 by Ord. No. 2019-14]
If the Director of Public Works allows the pretreatment or equalization of waste flows, the design and installation of the systems and equipment shall be subject to the review and approval of the Director of Public Works and the state (See Article III, Pretreatment of Wastewater).
A.
Maximum allowable industrial loadings limitations.
(1)
For all users connected to sewer lines that are tributary to the
City of Lebanon POTW, the Director of Public Works will not issue
permits that in combination with other industrial loads exceed the
values in the following table:
|
Pollutant
|

(2)
All limitations for metals represent total metals, regardless of
the valance state, or the physical or chemical form of the metal.
To administer these allowable loadings through IDPs, the Director
of Public Works may impose concentration-based limitations, or mass
limitations. For industrial users, the values written into IDPs for
the above pollutants shall apply at the end of the industrial waste
stream and prior to dilution with nonindustrial wastewaters.
(3)
Daily concentrations are the concentration of a pollutant discharged,
determined from the analysis of a flow-composited sample (or other
sampling procedure approved by the Director of Public Works) representative
of the discharge over the duration of a twenty-four-hour day or industrial
operating schedule of less than 24 hours.
(4)
All concentration limits for metals represent total metal unless
indicated otherwise.
(5)
Unless specifically identified in an industrial discharge permit,
an industrial user shall not discharge the locally limited pollutants
at concentrations significantly greater than domestic/background concentrations.
B.
Screening levels.
(1)
The following pollutants (list below is not all-inclusive) shall
not be discharged to the Lebanon Treatment Works exceeding concentrations
listed below without approval of the Director of Public Works:

(2)
Screening levels are numerical values above which actions are initiated
to evaluate, prevent or reduce adverse impacts due to flammability,
chemical reactivity, organic/solids loadings, interference, toxicity,
pass-through, or worker health and safety.
(3)
If any of the screening levels are exceeded, repeat sampling and
analyses may be required to verify compliance or noncompliance with
that screening level. If noncompliance is indicated, then the industrial
user may be required, at the discretion of the Director of Public
Works, to conduct an appropriate engineering evaluation to determine
the potential impact of the discharge of this pollutant to the City's
Lebanon Treatment Works or, alternatively, to develop a pollution
prevention plan specifically addressing the pollutant that exceeds
the screening level. This study or plan must be conducted under the
supervision and approval of the City. Should the evaluation indicate
the impact to be unsatisfactory, the industrial user shall reduce
the pollutant concentration to a satisfactory level. If the evaluation
supports development of an alternate site-specific limitation, then
the screening level shall be adjusted and administered as a limit
for the specific discharge.
(4)
If an industrial user proposes to discharge at concentrations greater
than the concentration-based screening level maintained by the Director
of Public Works, then the industrial user may be required to conduct
the evaluations described in the previous paragraph. Should the evaluations
support an alternate site-specific limitation, then the screening
level may, at the discretion of the Director of Public Works, be adjusted
as a special agreement for the industrial user and administered as
a permit limitation for the specific discharge.
C.
Special agreements. No statement contained in this section, except for § 136-10, Prohibited discharge standards, Subsections A and B, and § 136-11, Federal categorical pretreatment standards, shall be construed as preventing any special agreement or arrangement between the City and any industrial user whereby an industrial waste of unusual strength or character may be accepted by the City for treatment, provided that said 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 federal categorical pretreatment standards. Special agreement requests shall require submittal of a pollution prevention plan that specifically addresses the discharge for which a special agreement is requested.
A.
The discharge standards and requirements set forth in § 136-10, Prohibited discharge standards, § 136-11, Federal categorical pretreatment standards, and § 136-12, Local discharge restrictions, in this chapter, are established for the purpose of preventing discharges to the Lebanon Treatment Works which would harm either the sewers, wastewater treatment process or equipment; would have an adverse effect on the receiving stream; or would otherwise endanger lives, limb, public property or constitute a nuisance.
B.
To meet these objectives, the Director of Public Works may, from time to time, review and set more stringent standards or requirements than those established in § 136-10, Prohibited discharge standards, § 136-11, Federal categorical pretreatment standards, and § 136-12, Local discharge restrictions, in this chapter, if, in his or her opinion, such more stringent standards or requirements are necessary. At a minimum, this review will be performed at least once every five years. In forming his or her opinion, the Director of Public Works may give consideration to such factors as the quantity of waste in relation to flows and velocities in the sewers, materials of construction of the sewers, the wastewater treatment process employed, capacity of the wastewater treatment facility, degree of treatability at the wastewater treatment facility, pollution prevention activities and other pertinent factors. The limitations or restrictions on materials or characteristics of waste or wastewaters discharged to the sanitary sewer shall not be exceeded without the approval of the Director of Public Works.
C.
The Director of Public Works shall allow affected
industrial users reasonable time to comply with any changes to the
local limits. The conditions and schedule for compliance shall accompany
the written notification of amended local limits.
No user shall ever increase the use of process
water, or in any way attempt to dilute a discharge, as a partial or
complete substitute for adequate treatment to achieve compliance with
a discharge limitation unless expressly authorized by an applicable
pretreatment standard or requirement. The Director of Public Works
may impose mass limitations on users who are using dilution to meet
applicable pretreatment standards or requirements, or in other cases
when the imposition of mass limitations is appropriate.
Users implementing process changes may request
that compliance be determined based on mass limitations in lieu of
concentration limitations. Such mass-based limitations will be calculated
from the permitted concentration-based limitations and flows and shall
be equivalent to or less than the mass discharge in effect at the
time of the request. The intent of a mass-based limit is to encourage
and allow pollution prevention and/or water conservation measures
that might cause a facility to increase pollutant concentrations in
their discharge even though the total mass of the pollutant discharged
does not increase, and may in fact decrease. Decisions on granting
requests for mass-based compliance limitations will be based on user-specific
information and current operating conditions of the Lebanon Treatment
Works, and will be at the discretion of the Director of Public Works.
Implementation of mass-based limitations may not contravene any requirements
of federal or state laws and/or regulations implemented thereunder,
and may not waive applicable categorical pretreatment standards.
