A.
No user shall contribute or cause to be contributed,
directly or indirectly, any pollutant or wastewater which will interfere
with the operation or performance of the wastewater treatment plant.
These general prohibitions apply to all such users of a wastewater
treatment plant, whether or not the user is subject to National Categorical
Pretreatment Standards or any other national, state or local pretreatment
standards or requirements. A user may not contribute the following
substances to any wastewater treatment plant:
(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 to be injurious
in any other way to the wastewater treatment plant or to the operation
of the wastewater treatment plant. At no time shall two 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 5% nor any
single reading be 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, ketone,
aldehydes, peroxides, chlorates, perchlorates, bromates, carbides,
hydrides and sulfides and any other substances which the Borough,
the state or EPA has notified the user is a fire hazard or a hazard
to the system.
(2)
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 grease,
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, plastics, gas, tar, asphalt
residues, residues from refining or processing of fuel or lubricating
oil, mud or glass grinding or polishing wastes.
(3)
Any wastewater having a pH less than 6.0 or greater
than 9.0 or wastewater having any other corrosive property capable
of causing damage or hazard to structures, equipment and/or personnel
of the wastewater treatment plant.
(4)
Any wastewater containing toxic pollutants in sufficient
quantity, either singly or by interaction with other pollutants, to
injure or interfere with any wastewater treatment process, constitute
a hazard to humans or animals, create a toxic effect in the receiving
waters of the wastewater treatment plant or exceed the limitations
set forth in a categorical pretreatment standard; a toxic pollutant
identified pursuant to Section 307(a) of the Act.
(5)
Any noxious or malodorous liquids, gases or solids
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.
(6)
Any substance which may cause the wastewater treatment
plant's effluent or any other product of the wastewater treatment
plant, such as residues, sludge or scum, to be unsuitable for reclamation
and reuse or to interfere with the reclamation process. In no case
shall a substance discharged to the wastewater treatment plant cause
the wastewater treatment plant to be in noncompliance with sludge
use or disposal criteria, guidelines or regulations developed under
Section 405 of the Act or any criteria, guidelines or regulations
affecting sludge use or disposal developed pursuant to the Solid Waste
Disposal Act, the Clean Air Act, the Toxic Substances Control Act
or state criteria applicable to the sludge management method being
used.
(7)
Any substance which will cause the wastewater treatment
plant to violate its NPDES and/or state disposal system permit or
the receiving water quality standards.
(8)
Any dyes which interfere with the treatment process
or result in a violation of the effluent color limitations imposed
by PADER or EPA.
(9)
Any wastewater having a temperature which will inhibit
biological activity in the wastewater treatment plant resulting in
interference, but in no case wastewater with a temperature at the
introduction into the wastewater treatment plant which exceeds 40°
C. [104° F.] at the point of connection to the plant.
(10)
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 with
the wastewater treatment plant. In no case shall a slug load have
a flow rate or contain concentration or qualities of pollutants that
exceed for any time period longer than 15 minutes more than five times
the average 24 concentration, quantities or flow during normal operation.
(11)
Any wastewater containing any radioactive wastes
or isotopes of such half-life or concentration as may exceed limits
established by the Borough in compliance with applicable state or
federal regulations.
(12)
Any wastewater which causes a hazard to human
life or creates a public nuisance.
B.
When the Borough determines that a user is contributing
to the wastewater treatment plant any of the above-enumerated substances
in such amounts as to interfere with the operation of the wastewater
treatment plant, the Borough shall:
Upon the promulgation of the Federal Categorical
Pretreatment Standards for a particular industrial subcategory, the
federal standard, if more stringent than limitations imposed under
this Part 2 for sources in that subcategory, shall immediately supersede
the limitations imposed under this Part 2. The Borough shall notify
all affected users of the applicable reporting requirements under
40 CFR 403.12.
No person shall discharge wastewater containing

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 2.
The Borough reserves the right to establish
by ordinance more stringent limitations or requirements on discharges
to the wastewater disposal system if deemed necessary to comply with
the objectives presented herein.
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 Federal Categorical Pretreatment
Standards or in any other pollutant-specific limitation developed
by the Borough or state.
A.
Each user shall provide protection from accidental
discharge of prohibited materials or other substances regulated by
this Part 2. 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 Borough
for review, and the user shall complete such a plan when designated
by the Borough. The plan, as a minimum, must demonstrate compliance
with the requirements of the Commonwealth of Pennsylvania. No user
who commences contribution to the wastewater treatment plant after
the effective date of this Part 2 shall be permitted to introduce
pollutants into the system until accidental discharge procedures have
been approved by the Borough. 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 2. In the case of an accidental discharge,
it is the responsibility of the owner to immediately telephone and
notify the wastewater treatment plant of the incident. The notification
shall include location of discharge, type of waste, concentration
and volume and corrective actions.
B.
Written notice. Within five days following an accidental
discharge, the user shall submit to the Borough and 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 wastewater treatment plant, 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 2 or other applicable law.
C.
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 a dangerous discharge. Employers
shall ensure that all employees who may cause or suffer such a dangerous
discharge to occur are advised of the emergency notification procedure.
