Section 134-4 PROHIBITED DISCHARGE STANDARDS
A. No
user, industrial or domestic, shall contribute
or cause to be contributed, directly or indirectly, any pollutant or
wastewater
which will cause interference pass-through or violation of water
quality
standards. These general prohibitions apply to all users of the
municipal
wastewater system whether or not the use is subject to the Categorical
Pretreatment Standards or to any other national, state or local
pretreatment
standards or requirements. Furthermore, no use may contribute any of
the
following substances to the municipal wastewater system:
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 way to the municipal wastewater system. Included in this
prohibition are
waste streams with a closed-cup flashpoint of less than
one hundred forty
degrees Fahrenheit (140° F.) [sixty degrees Celsius (60°
C.)]. At no
time shall two (2) 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 five percent (5%) nor any single reading be over ten percent (10%)
of the
lower explosive limit (LEL) of the meter. Prohibited materials include
but are
not limited to gasoline, kerosene, naphtha, benzene, toluene, xylene,
ethers,
alcohols, ketones, aldehydes, peroxides, chlorates, perchlorates,
bromates, carbides,
hydrides and sulfides.
(Ord.
No. 2-05 Amended (A) 12-20-04-Effective Upon Passage)
2.
Solid or viscous substances in amounts
which will cause interference with the flow in a sewer, but in no
case
solids greater than one-half (1/2) inch [one and twenty-seven
hundredths (1.27)
centimeters] in any dimension.
3.
Any water or waste which contains wax,
grease, oil, plastic or other substances that will solidify or
become
discernibly viscous at temperatures between thirty-two degrees and one
hundred
fifty degrees Fahrenheit (32° and 150° F.).
a.
When it has been determined by the Director
of Public Works, or his authorized agent, that any restaurant is
discharging
grease into the sewer system which results in interference to the sewer
line,
including backup or maintenance work not otherwise necessary, then a
sewer
surcharge shall be added to the utility bill for that restaurant. The
sewer
surcharge shall be equal to the amount of the maintenance costs
incurred by the
town in eliminating the grease deposits from the sewer system, but in
any event
shall not be less than two hundred fifty dollars ($250).
(Ord.
No. 2-05 Replace “Town Engineer” with
“Director of Public Works” 12-20-04-Effective Upon Passage)
b.
Prior to the initial assessment of the
sewer surcharge, the owner or operator of such restaurant shall be
notified, in writing, of the Director of Public Work's determination.
The owner
or operator of said restaurant shall then be granted thirty (30)
days in
which to permanently correct and abate the condition causing the grease
to be
discharged into the sewer system. Unless the discharge of grease is
then
permanently eliminated, the initial sewer surcharge shall be
assessed ten
(10) days thereafter. No restaurant shall be entitled to more than one
(1) such
notice and grace period in which to correct the condition. The change
in
management or ownership shall not operate to give an existing
restaurant
facility an additional grace period in which to correct the
condition.
(Ord.
No. 2-05 Replace “Town Engineer” with
“Director of Public Works” 12-20-04-Effective Upon Passage)
c.
Thereafter, any further discharge of grease
into the sewer system by the restaurant facility which, in the
determination of
the Director of Public Works, creates a condition requiring maintenance
to
eliminate the grease deposit shall result in the assessment of a sewer
surcharge without further notice or grace. Sewer surcharge shall
continue to be
assessed until the grease discharge condition has been permanently
corrected to the satisfaction of the Town.

No. 2-05 Replace “Town Engineer” with
“Director of Public Works” 12-20-04-Effective Upon Passage)
4.
Any wastewater having a pH less than six
point zero (6.0) or more than nine point zero (9.0)
or which otherwise causes corrosive
structural damage to the system, Town personnel or equipment.
(Ord.
No. 2-05 Amended 12-20-04-Effective Upon Passage)
5.
Any wastewater
containing pollutants, including oxygen-demanding pollutants (BOD,
etc), in
sufficient quantity (flow or concentration), either singly or by
interaction with other pollutants, to pass through or
interfere
with the municipal wastewater system or any wastewater treatment or
sludge
process or constitute a hazard to humans or animals.
(Ord.
No. 2-05 Amended 12-20-04-Effective Upon Passage)
6.
Any pollutant which
will cause interference or pass through, including any toxic substances
in
amounts exceeding standards promulgated by the United States
Environmental
Protection Agency pursuant to Section 307(a) (33 U.S.C. Section 1317(a)
and
chemical elements or compounds, phenols or other taste or
odor-producing
substances or other substances which are not susceptible to treatment
or which
may interfere with the biological processes or efficiency of the
wastewater
treatment system, or that will pass through the system.
(Ord.
No. 2-05 Added 12-20-04-Effective Upon Passage)
7.
Any noxious or malodorous liquids, gases or solids or
other wastewater which, either singly or by interaction
with other
wastes, are sufficient to create a public nuisance or hazard to life or
are
sufficient to prevent entry into the sewers for maintenance and
repair.
8.
Any substance which
may cause the treatment plant effluent or any other residues, sludges
or scums
to be unsuitable for reclamation and reuse or to interfere with
the reclamation
process. In no case shall a substance discharged to the system
cause the
Town to be in noncompliance with sludge use or disposal regulations or
permits
issued under Section 405 of the Act, the Solid Waste Disposal Act, the
Clean
Air Act, the Toxic Substances Control Act or other state
requirements
applicable to the sludge use and disposal practices being used by the
Town.
9.
Any wastewater
which imparts color which cannot be removed by the treatment process,
such as
but not limited to dye wastes and vegetable tanning solutions, which
consequently imparts color to the treatment plant's effluent, thereby
violating
the Town's NPDES permit. Color (in combination with turbidity) shall
not cause
the treatment plant effluent to reduce the depth of the
compensation point
for photosynthetic activity by more than ten percent (10%) from the
seasonably
established norm for aquatic life.
10.
Any wastewater having a temperature
greater than one hundred fifty degrees Fahrenheit (150°)
[sixty-five degrees
Celsius (65° C.)], or which will inhibit biological activity
in the
treatment plant resulting in interference, but in no case wastewater
which
causes the temperature at the introduction into the treatment plant to
exceed
one hundred four degrees Fahrenheit (104° F.) [forty degrees
Celsius (40° C.)].
11.
Any wastewater containing any radioactive
wastes or isotopes except as specifically approved by
the Administrator in
compliance with applicable state or federal regulations.
12.
Any pollutants which result in the
presence of toxic gases, vapors or fumes within the system in a
quantity that
may cause worker health and safety problems.
13.
Any trucked or hauled pollutants, except
at discharge points designated by the Town in accordance with Section
134-12.
(Ord.
No. 2-05 Amended Section # 12-20-04-Effective Upon Passage)
14.
Stormwater, surface water, groundwater,
artesian well water, roof runoff, subsurface drainage, swimming pool
drainage,
condensate, deionized water, cooling water and unpolluted industrial
wastewater, unless specifically authorized by the Administrator.
15.
Any industrial wastes containing floatable
fats, waxes, grease or oils or which become floatable at the
wastewater
temperature at the introduction to the treatment plant during the
winter
season; but in no case industrial wastewater containing more than one
hundred
(100) mg/L of emulsified oil or grease.
16.
The discharge of a petroleum oil,
non-biodegradable cutting oil, or products of mineral oil origin, in
amounts
that cause interference or pass through.
(Ord.
No. 2-05 Amended 12-20-04-Effective Upon Passage)
17. Any sludges,
screenings or other residues from the pretreatment of industrial wastes.
18.
Any medical wastes, except as specifically
authorized by the Administrator in a wastewater permit.
19.
Any material identified as hazardous waste
according to 40 CFR 261 except as may be specifically authorized
by the
Administrator, and in accordance with Section 134-18N.
(Ord.
No. 2-05 Amended 12-20-04-Effective Upon Passage)
20. Any wastewater causing the treatment plant
effluent to show acute or chronic toxicity in excess of that allowed by
Virginia State Water Control Law, using a percentage of the discharge
and
aquatic test species chosen by the Administrator.
(Ord.
No. 2-05 Amended 12-20-04-Effective Upon Passage)
21. Recognizable
portions of the human or animal anatomy.
22.
Any wastes containing detergents,
surface-active agents or other substances which may cause excessive
foaming in
the municipal wastewater system.
23.
All discharges of storm water, surface
water, groundwater, roof runoff, subsurface drainage, or other waters
not
intended to be treated in the treatment facility, except as authorized
by the
Town.
(Ord. No. 2-05 Added (23) 12-20-04-Effective Upon Passage)
B. Wastes
prohibited by this section shall not be
processed or stored in such a manner that these wastes could be
discharged to
the municipal wastewater systems. All floor drains located in
process or
materials storage areas must discharge to the industrial user's
pretreatment
facility before connecting with the system.
C. Wastewater
survey. Upon request of the
Administrator, all industrial users shall submit information as to the
nature
and characteristics of their wastewater. The Administrator shall
prepare
a form for this wastewater survey and may periodically require
industrial users
to update the wastewater survey, or update thereof, within thirty (30)
days
from receipt of the Administrator's request. Failure to complete
the
wastewater survey, or any update thereon, shall constitute a violation
of this
Article.
