No user shall contribute, introduce or cause
to be contributed or introduced, directly or indirectly, 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 the user is subject to categorical pretreatment standards or
any other national, state, or local pretreatment standards or requirements.
A.Â
No user shall introduce or cause to be introduced
into the POTW the following pollutants, substances or wastewater:
(1)Â
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 text methods
specified in 40 CFR 261.21.
(2)Â
Wastewater having a pH less than 5.0 or more than
10.0 or otherwise causing corrosive structural damage to the POTW
or equipment.
(3)Â
Solid or viscous substances in amounts which will
cause obstruction of the flow in the POTW resulting in interference
(but in no case solids greater than 1/2 inch in any dimension). The
following substances are also prohibited: ashes, cinders, sand, mud,
straw, metal, glass, bones, rags, feather, tar, plastic, wood, paunch
manure, whole blood or blood products, lye, building materials, rubber,
hair, shavings, leather, china, ceramic wastes, asphalt, paint, waxes,
butcher offal, porcelain, and bentonite.
(4)Â
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.
(5)Â
Wastewater having a temperature greater than 104°
F. (40° 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
104° F. (40° C.);
(6)Â
Petroleum oil, non-biodegradable cutting oil, or products
of mineral oil origin, in amounts that will cause interference or
pass-through.
(7)Â
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.
(8)Â
Trucked or hauled pollutants or wastewater.
(9)Â
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.
(10)Â
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 Lower
Perkiomen Valley Regional Sewer Authority's NPDES permit.
(11)Â
Wastewater containing any radioactive wastes
or isotopes.
(12)Â
Stormwater, surface water, groundwater, artesian
well water, roof runoff, subsurface drainage, swimming pool drainage,
condensate, deionized water, non-contact cooling water, and unpolluted
wastewater.
(13)Â
Sludges, screenings, or other residues from
the pretreatment of industrial wastes.
(14)Â
Medical wastes.
(15)Â
Wastewater causing, alone or in conjunction
with other sources, the treatment plant's effluent to fail toxicity
test.
(16)Â
Detergents, surface-active agents, or other
substances which may cause excessive foaming in the POTW.
(17)Â
Wastewater causing an explosive hazard at the
point of discharge or at any point in the sewer interceptor system
or the POTW.
(18)Â
Any substance or condition which will cause
the POTW to violate its NPDES and/or state disposal system permit,
the receiving water quality standards, or any statute, rule, or regulation
of any public agency.
(19)Â
In no case shall a slug load have a flow rate
or contain concentration or qualities of pollutants that exceed any
time period longer than 15 minutes or contain more than five times
the average twenty-four-hour concentration of flow during normal operation,
or otherwise constitutes a slug discharge.
(20)Â
The discharge of toxic or hazardous wastes,
as defined in the Act or RCRA.
(21)Â
Total solids of such character or quantity as
to require unusual attention or expense in treatment.
(22)Â
Discharges prohibited by state or federal regulations.
(23)Â
Fats, oils, or greases of an animal or vegetable
origin in concentrations greater than 100 mg/l.
B.Â
When the control authority determines that a user(s)
is contributing to the POTW any of the above enumerated substances
in such amounts as to interfere with the operation of the POTW, the
control authority shall:
C.Â
Pollutants, substances or wastewater prohibited by
this section shall not be processed or stored in a manner that they
could be discharged to the POTW.
The categorical pretreatment standards found at 40 CFR Chapter I, Subchapter N, Parts 405 to 471, are hereby incorporated in this Part 5 by reference as though set forth in full.
A.Â
Where a categorical pretreatment standard is expressed
only in terms of either the mass or the concentration of a pollutant
in wastewater, the control authority may impose equivalent concentration
or mass limits in accordance with 40 CFR 403.6(c).
B.Â
When wastewater subject to a categorical pretreatment
standard is mixed with wastewater not regulated by the same standard,
the control authority shall impose an alternate limit using the combined
waste stream formula in 40 CFR 403.6(e).
C.Â
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.
D.Â
A user may obtain a net gross adjustment to a categorical
standard in accordance with 40 CFR 403.15.
Where the Lower Perkiomen Valley Regional Sewer
Authority's wastewater treatment system achieves consistent removal
of pollutants limited by national pretreatment standards, the Lower
Perkiomen Valley Regional Sewer Authority as control authority may
apply to the approval authority for modification of specific limits
in the national pretreatment standards. "Consistent removal" shall
mean reduction in the amount of a pollutant or alteration of the nature
of the pollutant by the wastewater treatment system to a less toxic
or harmless state in the effluent which is achieved by the system
in 95% of the samples taken when measured according to the procedures
set forth in Section 403.7(c)(2) of Title 40 of the Code of Federal
Regulations, "General Pretreatment Regulations for Existing and New
Sources of Pollution," promulgated pursuant to the Act. The Lower
Perkiomen Valley Regional Sewer Authority as control authority may
then modify pollutant discharge limits in the national pretreatment
standards if the requirements contained in 40 CFR 403.7 are fulfilled
and prior approval from the approval authority is obtained.
State requirements and limitations on discharges
shall apply in any case where they are more stringent than federal
requirements and limitations or those in this Part 5.
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. The control authority 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.
A.Â
Each user shall provide protection from accidental
discharge of prohibited materials or other substances regulated by
this Part 5. Facilities 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 control
authority for review and shall be approved by the control authority
before construction of the facility. All existing users shall complete
such a plan by January 1, 1994. No user shall be permitted to introduce
pollutants into the system until accidental discharge procedures have
been approved by the control authority. 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 this Part 5. In the case of an accidental
discharge, it is the responsibility of the user to immediately notify
the control authority of the incident. The notification shall include
location of discharge, type of waste, concentration and volume, and
corrective actions.
B.Â
Written notice. Within five days followings an accidental
discharge, the user shall submit to the control authority a detailed
written report describing the cause of the discharge and the measures
to be taken by the user to prevent similar future occurrences. Such
notification shall not relieve the user of any expense, loss, damage,
or other liability which may be incurred as a result of damage to
the POTW, fish kills, or any other damage to person or property, nor
shall such notification relieve the user of any fines, civil penalties,
or other liability which may be imposed by this Part 5 or other applicable
law.
C.Â
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 an accidental discharge. Employers
shall insure that all employees who may cause or suffer such an accidental
discharge to occur are advised of the emergency notification procedures.
A.Â
The Lower Perkiomen Valley Regional Sewer Authority
as control authority is authorized to establish local limits pursuant
to 40 CFR 403.5(c).
B.Â
The following pollutant limits are established to
protect against pass-through, interference, and sludge contamination.
No person shall discharge wastewater containing in excess of the following
limits:

C.Â
The above limits apply at the point where the wastewater
is discharged to the sewer. All concentrations from metallic substances
are for "total" metal unless otherwise indicated. The above local
limits are based on maximum allowable headworks loadings (MAHL) as
approved by the EPA. The Lower Perkiomen Valley Regional Sewer Authority
as control authority, through the issuance of an industrial waste
discharge permit, may establish other effluent limits consistent with
the approved MAHL. No such permits, however, shall waive or abrogate
federal or state categorical pretreatment standards or regulations.
Categorical concentrations apply at the end of the process waste stream.
No person shall discharge wastewater containing in excess of allowable
discharge limits as established by the Lower Perkiomen Valley Regional
Sewer Authority as control authority. The Lower Perkiomen Valley Regional
Sewer Authority as control authority may impose mass limitations in
addition to, or in place of, the concentration-based limitations.
