[Amended 12-4-2019 by Ord. No. 2019-14; 7-3-2024 by Ord. No. 2024-07]
A. No person(s) shall uncover, use, alter or disturb any public sewer
or appurtenance thereof without first obtaining written permission
from the Director of Public Works.
B. No person(s) shall make any connections with or opening into any
public sewer or appurtenance thereof without first obtaining a sewer
connection permit from the Director of Public Works.
C. There shall be two classes of sewer connection permits:
(1) For residential and commercial services, the owner(s) or their agent shall make application for a sewer connection permit at least 30 days' prior to planned sewer connection and in accordance with the provisions of Article
XIV of this chapter.
(2) For an establishment discharging industrial wastes, the owner(s) or their agent shall make application for a sewer connection permit at least 60 days' prior to planned sewer connection and in accordance with the provisions of Article
IV of this chapter.
A permit and inspection fee in accordance with the provisions of Code of the City of Lebanon, Chapter
68, Fees, shall be paid to the City at the time the application is filed.
D. 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 where no private sewer is available or where the rear
building cannot be connected to the public sewer system through an
adjoining alley, court, yard, or driveway. In such cases, the front
building sewer may be extended to the rear building and the whole
considered as one building sewer; however, the City does not and will
not assume any obligation or responsibility for damage caused by or
resulting from any such single connection aforementioned.
E. Existing building sewers may be used in connection with new buildings
only when they are found by the Director of Public Works or their
designee to meet all requirements of this chapter. Any required examinations
or tests of the existing building sewer to determine its adequacy
shall be at the expense of the owner/applicant.
F. 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 City of Lebanon Sewer Construction Standards. 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.
G. During installation of a new sanitary sewer main, the City may construct the service connections for existing buildings from the main to the curb or the property line or the edge of a right-of-way. Construction of the building sewer, including connection to the sewer main through the provided service connection, shall be the responsibility of the owner of the improved property to be connected. 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 owner's premises or its connection to the service connection. 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. The owner shall obtain an excavation permit (see Subsection
P below) and comply with all imposed conditions prior to any excavation of the City highway to achieve the aforementioned sewer connection.
H. 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 public sewer at the owner's
expense.
I. No person(s) shall connect 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.
J. No person shall obstruct the free flow of air through any building
sewer connection.
K. The connection of the building sewer into the public sewer shall
conform to the requirements of the City of Lebanon Sewer Construction
Standards and 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 or their designee before installation.
L. The applicant for the sewer connection 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 their designee.
This requirement shall also apply to repairs or alterations to building
connections, drains or pipes thereto.
M. Suitable provisions shall be made at the point of connection for
testing, for which responsibility shall rest with the holder of the
sewer connection permit.
N. No building sewer shall be covered until it has been inspected and
approved by the Director of Public Works or their designee. If any
part of the 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.
No connection to the public sewer shall be operational until the building
sewer has been found to be in compliance with all applicable rules
and regulations and all applicable permits are approved and in place.
O. The Department of Public Works shall maintain a record of all connections
made to public sewers under this chapter and all repairs and alterations
made to those building connections. All staff involved with the sewer
connection process shall assist the Director of Public Works in securing
data needed to create and maintain such records.
P. All excavations in the City right-of-way, if any, for building sewer installation shall require a permit in accordance with City Code Chapter
152, Article
II, Excavations. All open excavated areas shall 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, and in full accordance with applicable provisions of City Code Chapter
152.
Q. Proposed new discharges from residential or commercial sources involving loadings exceeding 50 population equivalents (5,000 gallons per day), or any new industrial discharge or 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.
[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.
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.
