[Ord. 422, 10/12/1994; as amended by Ord. 656, 4/9/2015]
1.
General Prohibitions. No industrial user shall introduce or cause
to be introduced into the POTW any pollutant or wastewater which causes
pass-through or interference. These general prohibitions shall apply
to all industrial 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 established by the
MTMA.
2.
Specific Prohibitions. No industrial 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 waste streams 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 or endangering MTMA personnel.
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 or which will constitute a hazard to MTMA
personnel.
E.
Wastewater 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 the MTMA Manager 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, is sufficient
to create a public nuisance or a hazard to life or to prevent entry
into the sewers for maintenance or repair.
J.
Wastewater containing any radioactive wastes or isotopes, except
in compliance with the applicable state or federal regulations.
K.
Stormwater, surface water, groundwater, artesian well water, roof
runoff or subsurface drainage.
L.
Sludges, screenings or other residues from the pretreatment of industrial
wastes.
3.
Pollutants, substances or wastewater prohibited by this section shall
not be processed or stored in such a manner that it could be discharged
to the POTW.
[Ord. 422, 10/12/1994; as amended by Ord. 616, 2/7/2007,
§ 1; and by Ord. 656, 4/9/2015]
1.
The categorical pretreatment standards found at 40 CFR, Chapter I, Subchapter N, Parts 405 to 471, are hereby incorporated as though the same were more fully set forth at length herein.
2.
Where a categorical pretreatment standard is expressed only in terms
of either the mass or the concentration of a pollutant in wastewater,
the MTMA Manager may impose equivalent concentration or mass limits
in accordance with 40 CFR 403.6(c).
3.
When wastewater subject to a categorical pretreatment standard is
mixed with wastewater not regulated by the same standard, the MTMA
Manager shall impose an alternate limit using the combined waste stream
formula in 40 CFR 403.6(e).
4.
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 the EPA
when developing the categorical pretreatment standard.
5.
A user may obtain a net gross adjustment to a Categorical Standard
in accordance with 40 CFR 403.15.
6.
Where the applicable categorical pretreatment standard requires compliance
with a best management practice (BMP) or pollution prevention alternative,
the user shall submit documentation required by the MTMA or the categorical
pretreatment standard necessary to determine the compliance status
of the user to the MTMA. At the discretion of the MTMA, and in consideration
of such factors as local high or low flow rates, holidays, etc., the
MTMA may modify the months during which reports are to be submitted.
[Ord. 422, 10/12/1994; as amended by Ord. 616, 2/7/2007,
§ 2]
1.
Specific pollutant limitations shall be controlled by each significant
industrial user's nondomestic wastewater discharge permit. Concentrations
or masses of each pollutant shall apply at the point designated as
the discharge point in the user's nondomestic wastewater permit.
All concentrations for metallic substances are for "total metal" unless
otherwise specified in the user's nondomestic wastewater discharge
permit.
2.
Notwithstanding any pollutant limitations required in an SIU's
nondomestic wastewater discharge permit or required pursuant to an
applicable categorical pretreatment standard, the MTMA shall not issue
nondomestic wastewater permits, which in total aggregate exceed the
following masses for each pollutant shown:
|

[Ord. 422, 10/12/1994; as amended by Ord. 656, 4/9/2015]
No industrial 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 MTMA Manager may impose mass limitations
on industrial users which are using dilution to meet applicable pretreatment
standards or requirements or in other cases when the imposition of
mass limitations is appropriate.
