[Adopted 6-16-1999]
A.
The Town
of Middlefield (the "Town"):
(1)
Is
the owner and operator of a public sewer; and
(2)
Does
not own, operate or have located within the territorial limits of
the Town any arrangements or devices for the treatment of sewage and
sludge; and
(3)
Has
entered into a written contract with the City of Middletown and the
City of Meriden (the "City" will be used to reference the City of
Middletown and/or the City of Meriden, depending on the context of
the use) whereby and wherein each City has agreed to accept, treat
and discharge the flow of sewage from certain parts of the Town's
public sewer into and out of the water pollution control facility
owned, operated and maintained by each City within the City, upon
terms and conditions set forth in each contract.
B.
This article
establishes the procedures for making connections to the public sewer
in the Town's sanitary sewer system. It also establishes specific
limits for pollutant discharges which by their nature or by their
interaction with sewage will be detrimental to the public health,
cause damage to the public sewer or the water pollution control facility,
pollute the waters of the state, or otherwise create a public nuisance.
C.
This article
is intended to:
(1)
Inform
the public as to the technical and administrative procedures to be
followed in obtaining connections to the Town's sanitary sewer system;
(2)
Prevent
the introduction of pollutants into the sanitary sewer system which
will interfere with the collection and/or treatment of sewage;
(3)
Prevent
the introduction of pollutants into the treatment system which will
pass through the system, inadequately treated, into the waters of
the state or the atmosphere, or otherwise be incompatible with the
system;
(4)
Improve
the opportunity to recycle and reclaim wastewaters and sludges from
the system.
D.
This article
shall apply to the Town. Except as otherwise provided herein, the
Water Pollution Control Authority of the Town shall otherwise implement
and enforce the provisions of this article.
E.
Purpose.
In addition to those areas previously sewered by using the City of
Middletown sewer systems, the Town of Middlefield has been directed
by the Connecticut Department of Energy and Environmental Protection,
pursuant to a pollution abatement order dated February 14, 1990, to
address failures of residential on-site subsurface wastewater disposal
systems (septic systems) in the Lake Beseck area of Middlefield.
F.
Findings and sewer avoidance. The Middlefield Water Pollution Control Authority (hereinafter "MWPCA") has determined that, due to the number of system failures and the difficulty in addressing these failures on site, the affected areas will be sewered and connected to a sewer in Meriden. The Connecticut Department of Energy and Environmental Protection, in its January 1978 "Report to the Joint Standing Committee on the Environment on the Establishment and Administration of a Municipal and Town Sewer Avoidance Program," declared sewer avoidance to be a desirable policy in rural communities where sewers do not exist and are not planned. It further recognized that sewer avoidance is a useful and, indeed, necessary tool to control and plan development consistent with historical or planned development patterns in many municipalities. The Department's recommendations served as the principal basis for the 1978 amendments to § 7-246 of the Connecticut General Statutes, which provided for the preparation of a water pollution control plan by municipal water pollution control authorities. The MWPCA concludes that sewer avoidance is generally appropriate as a policy for the entire Town of Middlefield. The State of Connecticut has continued to reflect these findings in its Conservation and Development Policies Plan for Connecticut 1992-1997. The flow capacity of the Lake Beseck sewer is limited. Therefore, the Town of Middlefield, in concurrence with the MWPCA, has resolved to ensure that all properties within the Lake Beseck Sewer Service Area, and the other two areas described in Subsection G(1)(b) of this section, are provided adequate use of the sewer service area facilities, and that the requirements of the Department of Energy and Environmental Protection shall be met. Accordingly, these ordinances are being adopted to regulate the use of the facilities constructed to serve the Lake Beseck Sewer Service Area and the other areas in Town which have been sewered. One of the purposes of this regulation is to prevent the proliferation of new construction in the Lake Beseck area unless it meets the Public Health Code requirements for an on-site septic system. The construction of the sewer system is to remedy a problem, not to provide for the over-development of structures in an environmentally sensitive area.
G.
Designation
of areas.
(1)
Designation
and delineation of sewer service and nonservice areas. The MWPCA hereby
adopts and incorporates by reference the map entitled "Lake Beseck
Sewer System Sewer Service Area 3/5/98 Middlefield, Connecticut,"
which designates the following:
(a)
The Lake Beseck Sewer Service Area;
(b)
All geographical area located within the Town of Middlefield but not depicted on the above-referenced map, and all areas, lots and parcels depicted on the map but not specifically included in Subsection G(1)(a) above are hereby established as areas where sewers are to be avoided and prohibited, except for that area currently serviced by the Middletown sewer line as shown in a map entitled "Route 66 and Zygo Area - 2 pages," attached hereto.[1]
[1]
Editor's Note: The maps referenced are on file in the Town
offices.
(2)
Designation
of additional areas. The MWPCA may designate additional areas to be
added to the sewer service area by changing the boundary line of the
area, after approval by the Connecticut Department of Energy and Environmental
Protection pursuant to § 22a-416 of the Connecticut General
Statutes, in accordance with the following requirements:
(a)
Prior to designating an area to be added to the sewer service area,
the MWPCA shall hold a public hearing. Notice of the public hearing
shall be published twice in a newspaper of general circulation in
the Town, the first not more than 15 days nor less than 10 days before
the hearing and the second at least two days before the public hearing.
In addition, notice shall be given, by certified mail, return receipt
requested, to each owner of record of land located in the area to
be designated.
(b)
The MWPCA may designate an additional area only upon a finding that:
[1]
The lots to be served in the proposed area are building lots which
contain existing buildings with on-site septic systems at the time
of the designation.
[2]
The area has experienced a high rate of septic system failure.
[3]
Site conditions make on-site repairs impracticable.
[4]
Other feasible alternatives do not exist.
[5]
The utilization of the facilities constructed to serve the sewer
service area by the additional area will not interfere with or preclude
those lots within the existing sewer service area from utilization
of the sewer service area facilities or otherwise diminish reserve
capacity to a point that interferes with utilization of the facilities
by lots lying within the service area.
[6]
The requirements of the interlocal agreement with the City are met.
[7]
Adequate capacity exists in the sewer system.
(c)
Designation of an additional area shall require the affirmative vote
of a majority of the Water Pollution Control Authority. "Majority"
in these regulations means a majority of the whole MWPCA and would
require a minimum of four affirmative votes.

accordance with § 7-257 of the Connecticut General Statutes,
the owner(s) of all houses, buildings or properties used for human
occupancy, employment, recreation or other purposes situated within
the Town of Middlefield 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 or combined sewer of the Town of Middlefield may, at the
option of the MWPCA and at the owners' expense, be required to install
a building sewer to connect their building drain to the public sewer
in accordance with the provisions of this article within 90 days after
date of official notice to do so.
(2)
It
shall be unlawful for any person to construct or repair any privy,
privy vault, septic tank, cesspool or other facility intended for
the disposal of sewage if public sewers are available.
(3)
No
unauthorized persons shall uncover, make any connections with or opening
to, discharge any waste into, use, alter, repair or disturb any public
sewer or appurtenance thereof without first obtaining a written permit
from the Sanitarian of the Town of Middlefield or other duly qualified
and licensed MWPCA agent (hereinafter referred to as "Inspector")
and the MWPCA.
(4)
No
certificate of occupancy for a building with a connection to a public
sewer shall be signed by the Inspector until the building sewer and
its connections are accepted by the MWCPA.
B.
New or changed discharge. Any person proposing a new discharge into the public sewer system or a substantial change in the volume or character of pollutants (also see § 370-12D) that are being discharged into the public sewer system shall notify the Inspector and the MWPCA at least 45 days prior to the proposed change or connection.
C.
Application
to permit connection to public sewer.
(1)
A person intending to connect a building drain from his property to the public sewer shall first obtain a permit to connect from the Inspector and the MWPCA. The application shall be made on forms provided by the Inspector and the MWPCA, and it shall be accompanied by a sketch or plan showing the proposed installation in sufficient detail to enable the Inspector to determine that the proposed installation meets the requirements of this article, the Town's ordinances and other applicable specifications, codes and laws. The application shall also include the proposed type and manner of connection, the authority to connect to the public sewer, the type and or change in use for the property, and the amount of estimated discharge. The MWCPA can approve the application if it meets the requirements as set forth within these regulations or deny the application if it does not meet these requirements. The application shall be signed by the owner of the premises to be served or his authorized agent and/or by the qualified contractor (see Subsection L) who has been chosen to perform the work of installing and connecting the building drain to the public sewer. Upon approval of the application and plan, a permit shall be issued to have the work performed by the stated contractor. In the event the premises changes ownership before the work is completed, or if another contractor is chosen to perform or finish the work, the original permit becomes void, and a new permit must be obtained by the new parties in interest.
(2)
A connection
to the public sewer will be made only after the building's plumbing
has been approved by the Inspector or in order to insure that minimum
standards are met for the installation. A fresh air vent shall be
required for the building and all plumbing shall be in good working
order. No trench containing a building drain or connection to the
sanitary sewer shall be backfilled until the Inspector has completed
an inspection of and approved the work. The water level in the trench
shall be maintained at a level below the sewer connection before the
cap is removed and while the connection is being made and until such
time as it has been inspected, approved and backfilled. The contractor
shall notify the Inspector 24 hours before starting any work authorized
under this permit.
(3)
Permits
to connect to the public sewer may be revoked and annulled by the
Inspector or MWPCA for such cause and at such time as he may deem
sufficient and the Town held harmless as a consequence of said revocation
or the cause thereof. All other parties in interest shall be held
to have waived the right to claim damages from the Town or its agents
on account of such revocation.
(4)
The
MWCPA shall own all sewer pipe, grinder pumps and connections to grinder
pumps from the sewer pipe, and those appurtenances within any existing
or planned right-of-way. Persons who connect to the public sewer shall
be responsible for repairs from their structure to any tee or wye.
If the MWCPA authorizes any extension of its sewer pipe to a private
party and enters into a developer's agreement, then that sewer pipe
extension shall become the property of the MWCPA upon acceptance.
D.
All costs
and expenses incidental to the installation and connection of the
building sewer shall be borne by the owners. The owners shall agree
in writing to indemnify the Town from any loss or damage that may
directly or indirectly be occasioned by the installation of the building
sewer.
E.
A separate
and independent building sewer shall be provided for every building;
except where a building (the "rear building") stands on an interior
lot and no public sewer is available or can be constructed to the
rear building through an adjoining alley, courtyard or driveway, the
building sewer that provides service for the building which fronts
on the public sewer may be extended to the rear building and the whole
considered as one building sewer; but the Town does not and will not
assume any obligation or responsibility for damage caused by or resulting
from any such aforementioned connection.
F.
Existing
building sewers may be used in connection with new buildings only
when they are found, on examination and test by the Inspector, to
meet all requirements of this article.
G.

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, and trench and connection of the building
sewer to the public sewer shall all conform to the requirements of
the Building and Plumbing Code or other applicable rules and regulations
of the Town and State of Connecticut. In the absence of code provisions
or in amplification thereof, the materials and procedures set forth
in appropriate specifications of the ASTM (American Society of Testing
Materials) and WPCF (Water Pollution Control Federation) Manual of
Practice No. 9 shall apply.
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,
sanitary sewage carried by such building drain shall be lifted by
means approved by the Town Inspector and the City and discharged to
the building sewer. Duplex lift systems shall be provided for commercial
and industrial buildings.
I.
No persons
shall make connection of roof downspouts, foundation drains, 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 sewer.
J.
All excavations
for building sewer installation 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 Town.
K.
No building
sewer shall be constructed within 25 feet of a water supply well.
If a building sewer is constructed within 25 to 75 feet of a water
supply well, it shall be constructed in accordance with all applicable
guidelines promulgated by the Commissioner.
L.
All building
sewers shall be installed by a qualified individual who possesses
a valid license issued under Chapter 393 of the Connecticut General

construction practices and materials shall be used to install building
sewer connections:
(1)
The
building sewer connection must be minimum four-inch PVC plastic sewer
pipe and carried to within five feet (1.5 meters) of cellar wall;
from this point five feet (1.5 meters) of four-inch (10.16 cm) extra-heavy
soil pipe is to be used through cellar wall. The pipe must have a
true grade no less than 1/4 inch to one foot. All joints to be made
with braided jute and compound, or suitable rubber gasket or "O" ring.
All pipes must be bedded with sand one foot under the pipe, with six
inches of sand on the top and sides of the pipe.
(2)
Connection
of the building sewer to the main sewer line should be made to existing
wyes wherever possible. Where a wye does not exist, the main sewer
line shall be cut and a wye inserted with suitable leakproof connections.
The building sewer to wye connection shall be made watertight and
gastight and proved by a pipe test.
(3)
All
cleanouts must be carried above the cellar floor to prevent surface
water from entering the sewer. No surface water shall be allowed to
enter the sewer. All work in connection with main house drain must
be performed by a licensed plumber and in accordance with local, state
and national building and plumbing codes or by someone with an exemption
thereunder.

as are specifically designated as storm sewers and discharged to a
watercourse in accordance with all applicable state and federal laws
and regulations.
C.
No user
shall contribute or cause to be contributed, directly or indirectly,
any pollutant or wastewater which will interfere with the operation
or performance of the WPCF. These general prohibitions apply to all
such users of the WPCF, whether or not the user is subject to National
Categorical Pretreatment Standards or any other federal or state pretreatment
standards or requirements. A user shall not contribute the following
substances to the WPCF:
(1)
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 WPCF or to the operation of the WPCF. At no time shall
two successive readings on an explosion hazard meter, at the point
of discharge into the sewage collection 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.
(2)
Solids
or viscous substances which may cause obstruction to the flow in a
sewer or other interference with the operation of the WPCF, including
substances such as, but not limited to, grease, garbage with particles
greater than 1/2 inch in any dimension, animal guts or tissues, paunch
manure, bones, hair, hides or fleshings, entrails, whole blood, feathers,

shall be established under the discharger's state discharge permit.
(4)
Any
sewage 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 or plant life, create a toxic effect in the receiving waters
of the WPCF, 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 Act.
(5)
Any
noxious or malodorous sewage, gases or solids which either singly
or by interaction with other sewage are sufficient to prevent entry
into the public sewers for their maintenance and repair.
(6)
Any
sewage which, by interaction with other sewage in the public sewer
releases obnoxious gases, forms suspended solids which interfere with
the collection system, or creates a condition which may be deleterious
to structures and treatment processes or which may cause the effluent
limitations of the WPCF's NPDES permit to be exceeded.
(7)
Any
substance which may cause the WPCF's effluent or any other produce
of the WPCF, such as residues, sludges or scums, to be unsuitable
for reclamation process where the WPCF is pursuing a reuse and reclamation
program. In no case shall a substance discharged to the WPCF cause
the facility to be in noncompliance with sludge use or disposal criteria,
guidelines or regulations developed under Section 405 of the Act;
any criteria, guidelines or regulations affecting sludge use or disposal
developed pursuant to the Resource Conservation and Recovery Act,
Clean Air Act, the Toxic Substances Control Act, or state criteria

to treatment only to such degree that the WPCF effluent cannot meet
the limits stipulated in the City's NPDES permit.
D.
The following
described substances, materials, waters or waste shall be limited
in discharges to public sewers to concentrations or quantities which
will not harm either the sewers, WPCF, will not have an adverse effect
on the receiving watercourse, or will not otherwise endanger public
property or constitute a nuisance. The Commissioner may set lower
limitations if more severe limitations are necessary to meet the water
quality standards of the receiving watercourse or if the state regulations
are changed. The limitations or restrictions on materials or characteristics
of sewage discharged to the public sewer are as follows:
(1)

has been made to the sewerage system or that any flows to the sewerage
system have been increased in violation of any provision of this article,
the MWPCA may order the disconnection of the noncomplying property
from the sewerage system or may issue such other orders or take such
other actions as may be allowed by law to bring such properties into
compliance with this article. The Inspector, in addition to the MWPCA,
also has the authority to enforce this article. The offender shall,
within the period of time stated in such notice, permanently cease
all violations.
B.
Any person who continues any violation beyond the time limit provided for in Subsection A shall be guilty of a violation and, on conviction thereof, shall be fined in an amount not exceeding $100 for each separate offense. Each day in which any such violation shall continue beyond the time limit provided for in Subsection A shall be deemed a separate offense. In addition, the MWPCA or the Inspector may assess civil penalties in the amount of $100 per day pursuant to Connecticut General Statutes § 7-148(c)(10)(A).
C.
Any person
who is found to be in violation of any of the provisions of this article
shall become liable to the Town, the City, or both, for any expense,
loss or damage occasioned the Town or the City by reason of such violation.
D.
The MWPCA
or the Inspector may petition Superior Court to enforce any of the
orders issued herein and to enforce any of its ordinances. Any enforcement
action may also seek other appropriate legal and/or equitable relief,
including environmental remediation. Any action brought by the MWPCA
or the Inspector may recover reasonable attorneys' fees, court costs,
and other expenses, including, but not limited to, sampling and monetary
expenses, in addition to actual damages incurred by the Town of Middlefield.
E.
