A.Â
No person shall discharge, release, place, or allow to be placed
any wastewater of any nature into any stream, storm sewer, waterway
or any other place within the municipality other than the sanitary
sewers.
B.Â
No user shall contribute, cause, or allow to be discharged, directly
or indirectly, any pollutant or wastewater which will interfere with
the operation or performance of the sewer system or the WVSA facilities.
These general prohibitions apply to all users of the sewer system
whether or not the user is subject to any pretreatment standards or
requirements or any other federal, state, or local pretreatment standards
or requirements. A user shall not contribute the following substances
to the sanitary sewer system or the WVSA's facilities:
(1)Â
Any liquids, solids or gases which, by reason of their nature or
quantity, are, or may be, sufficient, either alone or by interaction
with any other substance, to cause fire or explosion or be injurious
in any other way to the WVSA or to the operation of the WVSA's
treatment plant. Discharges prohibited under this section shall include,
but not be limited to, waste streams with a closed-cup flash point
of less than 140° F. or 60° C., using the test methods specified
in 40 CFR 261.21. At no time shall two successive readings on an explosion
hazard meter, at the point of discharge into the system (or 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, kerosene, naphtha, benzene,
toluene, xylene, ethers, alcohols, ketones, aldehydes, peroxides,
chlorates, perchlorates, bromates, carbides, hydrides and sulfides
and any other substances which cause or contribute to a fire hazard
or a hazard to the sewer system in the quantities or concentrations
discharged.
(2)Â
Any wastewater having a pH value less than 6.0 or greater than 11.5
in any grab sample, or a wastewater having any other corrosive property
capable of causing damage or hazard to structures, equipment, and/or
personnel.
(3)Â
Solid or viscous substances which may cause obstruction to the flow
in a sewer or other interference with the operation of the wastewater
treatment facilities, such as but not limited to 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,
ashes, cinders, sand, spent lime, stone or marble dust, metal, glass,
straw, shavings, grass clippings, rags, spent grains, spent hops,
wastepaper, wood, plastic, gas, tar, asphalt residues, mud, or glass
grinding or polishing wastes.
(4)Â
Any pollutants, including oxygen-demanding pollutants (BOD, etc.),
released at a flow rate and/or pollutant concentration which a user
knows or has reason to know will cause interference to the sewer system.
In no case shall a discharge have a flow rate or contain a concentration
of pollutants that exceed for any time period longer than 15 minutes
more than five times the average twenty-four-hour flow or concentration
of pollutants during normal operation. Notwithstanding the criteria
above, any slug discharge shall be prohibited.
(5)Â
Any wastewater having a temperature which will inhibit biological
activity in the WVSA treatment plant resulting in interference, but
in no case any wastewater with a temperature at the introduction into
the WVSA facilities which exceeds 40° C. (104° F.).
(6)Â
Any wastewater containing toxic pollutants in sufficient quantity,
either singly or by interaction with any wastewater treatment process,
which will cause pass-through or interference or exceed the limitation
set forth in a National Categorical Pretreatment Standard or local
limit.
(7)Â
Any discharge which may result in the presence of toxic gases, vapors,
or fumes within the treatment system, in a quantity that may cause
acute worker health and safety problems or is sufficient to create
a public nuisance or hazard.
(8)Â
Petroleum oil, nonbiodegradable cutting oil, or products of mineral
oil origin in amounts that will cause interference or pass-through.
(9)Â
Any trucked or hauled pollutants, except at discharge points designated
by the WVSA.
(10)Â
Any substance which may cause the WVSA treatment plant's
effluent or any other product of the WVSA, such as residues, sludges,
or scums, to be unsuitable for reclamation and reuse or to interfere
with the reclamation or disposal process. In no case shall a substance
discharged to the WVSA's facilities cause the WVSA to be in noncompliance
with sludge use or disposal criteria, guidelines or regulations developed
under Section 405 of the Act,[1] any criteria, guidelines or regulations affecting sludge
use or disposal developed pursuant to the Solid Waste Disposal Act,[2] the Clean Air Act,[3] the Toxic Substances Control Act,[4] or state criteria applicable to the sludge management
or disposal method being used.
(11)Â
Any substance which will cause or contribute to a violation
of the WVSA's NPDES permit or cause interference or pass-through,
as established by the local limits adopted by the WVSA.
(12)Â
Any wastewater with color not removed in the treatment process,
such as, but not limited to, dye wastes and vegetable tanning solutions,
such as would cause or contribute to pass-through or interference.
(13)Â
Any wastewater containing any radioactive wastes or isotopes
by such half-life or concentration as may exceed limits established
by the Executive Director in compliance with applicable state or federal
regulations.
(14)Â
Any substance which causes a hazard to human life or creates
a public nuisance.
C.Â
When a local limit has been developed to implement any of the above
prohibited waste standards, compliance with the local limit shall
be deemed compliance with the prohibited waste standard unless the
user has reason to know that the discharge, notwithstanding the local
limit, has a reasonable potential to cause interference or pass-through.
Upon the promulgation of National Categorical Pretreatment Standards
for a particular industrial category or subcategory, the national
standards, if more stringent than limitations imposed under this chapter
for sources in that subcategory, shall immediately supersede the limitations
imposed under this chapter. The Executive Director shall notify all
affected users of the applicable reporting requirements under 40 CFR
403.12. However, failure to notify a categorical user of the applicable
regulations shall not act to excuse any such user from its duty to
comply with applicable law.
No user shall contribute or cause to be contributed any discharge
which by nature shall cause an upset in the performance of the WVSA's
treatment system or pass-through or interference such that the WVSA
will violate or will be in danger of violating any provision of its
NPDES permit or applicable state or federal regulations.
A.Â
The WVSA will develop local limits as set forth in 40 CFR 403.5,
and such other local limits as it deems advisable for the safe, efficient
and reliable operation of the sewer system and the WVSA facilities.
Local limits shall be applicable to such users as WVSA shall designate,
including but not limited to all industrial users.
B.Â
WVSA may develop equivalent mass limits or equivalent concentration
limits to implement categorical pretreatment standards when requested
by a categorical industrial user, pursuant to the provisions at 40
CFR 403.6(c)(5) and (6).
State requirements and limitations on wastewater indirect discharge
shall apply in any case where they are more stringent than federal
and/or local requirements and limitations or those in this chapter.
The municipality reserves the right to establish more stringent limitations or requirements on discharges to the sewer system if deemed necessary to comply with the objectives presented in § 464-1 of this chapter.
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 the limitations contained in the National Categorical Pretreatment Standards, or in any pollutant-specific limitations developed by the WVSA or the commonwealth; provided, however, that dilution may be an acceptable means of complying with certain of the prohibitions set forth in § 464-3, e.g., the pH and temperature prohibitions, if such dilution is authorized by an industrial wastewater discharge permit.
No user shall discharge any stormwater, including but not limited
to basement or foundation drainage, or any uncontaminated cooling
water into the sanitary sewer system, provided that such discharges
are allowable into those portions of the sewer system (if any) that
are designated combined sewers by the municipality. When, upon application
to do so, the direct discharge of uncontaminated cooling water has
been prohibited by the PADEP, the municipality and WVSA may permit
such a discharge into the sanitary sewer system upon application by
the user to do so.
