[Ord. 486, 3/21/2002, § 2.1]
1.
General Prohibitions. No user shall introduce or cause to be, introduced
into the POTW any pollutant or wastewater which causes pass through
or interference. These general prohibitions apply to all users of
the POTW whether or not they are subject to categorical pretreatment
standards or any other national, state, or local pretreatment standards
or requirements.
2.
Specific Prohibitions. No user shall introduce or cause to be introduced
into the POTW the following pollutants, substances, or wastewater:
A.
Pollutants which create a fire or explosive hazard in the POTW, including,
but not limited to, wastestreams with a closed-cup flashpoint of less
than 140° F. (60° C.) using the test methods specified in
40 CFR § 261.21.
B.
Wastewater having a pH less than 5.0 or otherwise causing corrosive
structural damage to the POTW or equipment.
C.
Solid or viscous substances in amounts which will cause obstruction
of the flow in the POTW resulting in interference.
D.
Pollutants, including oxygen-demanding pollutants (BOD, etc.), 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.
E.
Wastewater with a temperature 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 104° F. (40° C.).
F.
Petroleum oil, nonbiodegradable cutting oil, or products of mineral
oil origin, in amounts that will cause interference or pass through.
G.
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.
H.
Trucked or hauled pollutants, except at discharge points designated by MACM in accordance with § 18-314 of this Part.
I.
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.
J.
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 MACM NPDES permit.
K.
Wastewater containing any radioactive wastes or isotopes except in
compliance with applicable state or federal regulations.
L.
Stormwater, surface water, ground water, artesian well water, roof
runoff, subsurface drainage, swimming pool drainage, condensate, deionized
water; noncontact cooling water, and unpolluted wastewater, unless
specifically authorized by MACM.
M.
Sludges, screenings, or other residues from the pretreatment of industrial
wastes.
N.
Medical wastes, except as specifically authorized by MACM in a wastewater
discharge permit.
O.
Wastewater causing, alone or in conjunction with other sources, the
treatment plant's effluent to fail a toxicity test.
P.
Detergents, surface-active agents, or other substances which may
cause excessive foaming in the POTW.
Q.
Wastewater causing two readings on an explosion hazard meter at the
point of discharge into the POTW, or at any point in the POTW, of
more than 5% or any single reading over 10% of the lower explosive
limit of the meter.
|
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 POTW.

[Ord. 486, 3/21/2002, § 2.2]
1.
The categorical pretreatment standards found at 40 CFR, Chapter I,
Subchapter N, Parts 405-471 are hereby incorporated.
A.
Where a categorical pretreatment standard is expressed only in terms
of either the mass or the concentration of a pollutant in wastewater,
MACM 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, MACM shall
impose an alternate limit using the combined wastestream formula in
40 CFR § 403.6(e).
C.
A user may obtain a variance from a categorical pretreatment standard
if the user can prove, pursuant to the procedural and substantive
provisions in 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 standard
in accordance with 40 CFR § 403.15.
[Ord. 486, 3/21/2002, § 2.3]
(Reserved)
[Ord. 486, 3/21/2002, § 2.4]
No industrial user shall discharge wastewater containing a mass
of any pollutant which, when taken together with the mass of that
pollutant discharged by all other industrial users will-cause the
mass of the pollutant to exceed the mass of that pollutant specified
in the headworks industrial allowance which has been apprised by the
approval authority for the POTW into which the industrial user discharges.
MACM may establish local limits regulating the discharge of specific
pollutants by industrial users: Discharging any pollutant in excess
of a local limit or an industrial user's permit shall constitute a
violation of this Part.
[Ord. 486, 3/21/2002, § 2.5]
MACM reserves the right to establish, by ordinance or in wastewater
discharge permits, more stringent standards or requirements on discharges
to the POTW.
[Ord. 486, 3/21/2002, § 2.6]
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. MACM 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.
