No unauthorized person shall:
A.
Break, damage, destroy, uncover, deface or tamper with any equipment
or materials belonging to the Town of Lunenburg and used or intended
to be used for the purposes of making measurements, tests or examination
of sewage or wastes.
B.
Remove, damage or interfere with the functioning of any pipe, main,
manhole, manhole cover, building, apparatus or equipment used in the
collection, conveyance or treatment of sewage or industrial wastes.
C.
Place or cause to be placed in any manhole or sewer pipe or main
any material which results or is likely to result in the stopping
or obstructing of the normal flow of sewage or wastes.
No user shall introduce or cause to be introduced directly or
indirectly into the POTW any pollutant or wastewater which causes
improper pass-through or interference. These general prohibitions
apply to all users of a POTW, whether or not the user is subject to
national categorical pretreatment standards or requirements. A user
may not contribute the following substances to any POTW:
A.
Any wastewater containing toxic pollutants or poisonous liquids,
gases or solids, including heavy metals, in sufficient quantity which,
either singly or by interaction with other wastes, injure or interfere
with any wastewater treatment process, constitute a hazard to humans
or animals, create a public nuisance, create any hazard in the waters
receiving treated effluent from the POTW treatment plant or 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.
B.
Any wastewater, liquid or vapor having a temperature higher than
150° F. No user may discharge a waste which shall cause the temperature
at the POTW influent to exceed 104° F.
C.
Any wastewater that have a pH lower than 5.5 or higher than 9.5 or
having any other corrosive property capable of causing damage or hazard
to structures, equipment, process or personnel at the POTW.
D.
Any wastewater containing fats, waxes, grease or oils or containing
substances which may solidify or become viscous at temperatures between
32° F. and 150° F.
E.
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 POTW or to the operation of the POTW. At no
time shall two successive readings on an explosion hazard meter at
the point of discharge into the 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. Prohibited materials include but are not
limited to gasoline, fuel oil, kerosene, naphtha, benzene, toluene,
xylene, ethers, alcohols, ketones, aldehydes, peroxides, chlorates,
perchlorates, bromates, carbides, hydrides and sulfides and any other
substance which the Town, the state or EPA has notified the user is
a fire hazard or a hazard to the system.
F.
Any pollutant which creates a fire or explosion hazard in the POTW,
including but not limited to waste streams with a closed-cup flashpoint
of less than 140° F. using the test methods set forth in 40 CFR
261.21.
G.
Any solid or viscous substances in quantities or of such size as
to be capable of causing obstruction to the flow in sewers or other
interference with the proper operation of the POTW, such as but not
limited to ashes, cinders, disposable wipes, spent lime, sand, mud,
straw, shavings, metal, glass, rags, feathers, bones, tar, plastics,
wood, unground garbage, grass clippings, whole blood, paunch manure,
hair and fleshings, entrails, grease, paper dishes, cups, milk containers,
etc., either whole or ground by garbage grinders.
H.
Any garbage that has not been properly shredded. The installation
and operation of any garbage grinder equipped with a motor of 3/4
horsepower or greater shall be subject to the review and approval
of the Department.
I.
Water or waste containing dyes or other color which cannot be removed
by biological processes and which requires special chemical treatment
in order for POTW treatment plant effluent to meet standards set by
state law or rules, regulations or orders made pursuant to law.
J.
Water or waste which requires excessive quantities of chlorine for
stabilization in addition to biological treatment.
K.
Any water or waste containing phenols or other taste- or odor-producing
substances in such concentrations as to exceed limits which may be
established by the Commission as necessary, after the treatment of
the composite wastewater, to meet the requirements of the state, federal
or other public agencies or jurisdiction for such discharge to the
receiving waters.
L.
Any radioactive waste or isotopes in excessive amounts or of such
half-life or concentration as may exceed limits established in applicable
state or federal regulations or by the Commission.
M.
Pollutants, including oxygen-demanding pollutants (BOD, for example),
released in a discharge at a flow rate and/or pollutant concentration
which, either singly or by interaction with other pollutants, will
cause interference with the POTW. In no case shall materials or flow
be discharged in such amounts as to constitute a slug as defined in
these regulations.
N.
Any substance which may cause the POTW's effluent or any other product
of the POTW, such as residue, sludge or scum, to be unsuitable for
reclamation and reuse or to interfere with the reclamation process.
In no case shall a substance discharged to the POTW cause the POTW
to violate its NPDES and/or state disposal system permit or the receiving
water quality standards.
O.
Any wastewater which causes a hazard to human life or creates a public
nuisance, including any pollutants which result in the presence of
toxic gases, vapors or fumes within the POTW in a quantity that may
cause acute worker health and safety problems.
P.
It shall be unlawful for any person to discharge into the sewer system
or cause to be discharged into the sewer system the sludge resulting
from pretreatment of waters or wastewaters.
Q.
Any petroleum oil, nonbiodegradable cutting oil or products of mineral
oil origin in amounts that will cause interference or improper pass-through.
R.
Any trucked or hauled pollutants, except at discharge points designated
by the POTW.
S.
Glycol or wastewater produced from the stripping of wax floors, unless
the proponent can provide sufficient evidence that the proposed concentration
of these wastes will not harm the collection system or POTW.
T.
Prohibited pollutants, substances or wastewater shall not be processed
or stored in such a manner or location that they could be discharged
to the POTW.
Except where expressly authorized to do so by an applicable
categorical 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 categorical pretreatment standard or other discharge
limitation. The control authority may impose mass limitations on industrial
users which are using dilution to meet applicable pretreatment standards
or in other cases where the imposition of mass limitations is appropriate.
A.
Concentration limits.
(1)
No person shall discharge wastewater containing concentrations
in excess of (unless authorized in user's discharge document):
(2)
The temperature of discharges shall not exceed 150° F. No
user may discharge a waste which shall cause the temperature at the
POTW influent to exceed 104° F.
(3)
Discharge limitations for specific pollutants will be determined
by the Superintendent on an individual basis and specified on the
wastewater discharge permit. In no case will limitations specified
be less stringent than applicable federal or state guidelines. The
POTW develops and enforces specific limits to implement the prohibition
against improper pass-through and interference and the specific prohibitions
presently set forth at 40 CFR 403.5(b) and to insure compliance with
the POTW's NPDES permit. These local limits are deemed pretreatment
standards for purposes of Section 307(d) of the Act.
B.
Instantaneous discharge flow rate limits.
(1)
The instantaneous discharge flow rate shall not exceed the following
limits:
|
Average Flow
(gallons per day)
|
Allowable Ratio of Instantaneous Flow Rate to Average
Flow
| |
|---|---|---|
|
50,000 to 100,000
|
3
| |
|
100,000 to 500,000
|
2
| |
|
More than 500,000
|
1.5
|
(2)
Users whose average flow is less than 50,000 gallons per day
shall not discharge an instantaneous rate of flow in excess of 150,000
gallons per day.
C.
No person shall discharge any waste or wastewater in a slug.
D.
The cities may establish by ordinance and the Commission by regulations
or by the grant or modification of wastewater discharge permits more
stringent standards or requirements on discharges to the POTW.
A.
Internal/External grease, oil and sand interceptors shall be installed
and operational when they are required by the local or state Plumbing
Code for the proper handling of liquid wastes containing grease in
excessive amounts or any flammable wastes, sand or other harmful ingredients,
except that such interceptors shall not be required for private living
quarter or dwelling units. All interceptors shall be of a type and
capacity approved by the Commission and shall be located so as to
be readily and easily accessible for cleaning and inspection.
B.

Editor's Note: Appendix C is included as an attachment to this chapter.
The categorical pretreatment standards set forth in 40 CFR, Chapter 1, Subchapter N, are hereby incorporated into these regulations and adopted by the Town subject to the following:
A.
Where a categorical pretreatment standard is expressed only in terms
of either the mass or the concentration of a pollutant in wastewater,
the Commission may impose equivalent concentration or mass limits
in accordance with 40 CFR 403.6(c).
B.
When wastewater subject to a categorical pretreatment standard is
mixed with wastewater not regulated by the same standard, the Commission
shall impose an alternate limit using the combined waste stream formula
in 40 CFR 403.6(e). The combined waste stream formula is only applicable
when the process effluent is mixed prior to treatment with wastewaters
other than those generated by the regulated process. The combined
waste stream formula cannot be used in situations where there is no
treatment for the regulated process effluent.
C.
A user may obtain a variance from a categorical pretreatment standard
if the user can prove, pursuant to the procedural and substantive
requirement of 40 CFR 403.13, that factors relating to its discharge
are fundamentally different from the factors considered by EPA when
developing the categorical pretreatment standard.
D.
A user may obtain a net gross adjustment to a categorical pretreatment
standard in accordance with 40 CFR 403.15.
E.
If state or local limitations are more stringent than the categorical
pretreatment standards, then the state or local standard shall apply.
It is the intent of this section that the most stringent standards
shall apply.
A.
Regulations. Each user shall provide protection from accidental discharge
of prohibited materials or other substances regulated by these regulations.
Facilities required to prevent accidental discharge of prohibited
materials shall be provided and maintained at the owner's or user's
own cost and expense. Detailed plans showing facilities and operating
procedures to provide this protection shall be submitted to the Town
for review and shall be approved by the Town before construction of
the facility. Review and approval of such plans and operating procedures
shall not relieve the industrial user from the responsibility to modify
the user's facility as necessary to meet the requirements of these
regulations. In the case of an accidental discharge, it is the responsibility
of the user to immediately telephone and notify the Department of
the incident.
B.
Notice to employees. A notice shall be permanently posted on the
user's bulletin board or other prominent place advising employees
whom to call in the event of a dangerous discharge. Employers shall
ensure that all employees who may cause or suffer such a dangerous
discharge to occur are advised of the emergency notification procedure.
C.
Accidental discharge/slug control plans. At least once every two
years, the Department shall evaluate whether each significant industrial
user needs an accidental discharge/slug control plan. The Department
may require any user to develop, submit for approval and implement
such a plan. Alternately, the Department may develop such a plan for
any user. An accidental discharge/slug control plan shall address,
at a minimum, the following:
(1)
Description of discharge practices, including nonroutine batch
discharges.
(2)
Description of stored chemicals.
(3)
Procedures for immediately notifying the Department of any accidental
or slug discharges.
(4)
Procedures to prevent adverse impact from any accidental or
slug discharge. Such procedures include but are not limited to inspection
and maintenance of storage areas, handling and transfer of materials,
loading and unloading operations, control of plant site runoff, worker
training, building of containment structures or equipment, measures
for containing toxic organic pollutants, including solvents, and/or
measures and equipment for emergency use.
(5)
Such other plans, methods, steps, systems or requirements as
the Department may require.
D.
All categorical and noncategorical industrial users shall notify
the Department immediately of all discharges that could cause problems
to the POTW, including any slug loadings as defined by Section 403.5(b)
of 40 CFR (as the same may from time to time be amended) by the industrial
user.
