318, 5/29/2007]
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 POTW. These general prohibitions
apply to all such users of a POTW 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 POTW:
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 be injurious in any other
way to the POTW or to the operation of the POTW. 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 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 the CHJA, 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, wastepapers, wood, plastics, gas, tar, asphalt
residues, residues from refining, or processing of fuel or lubrication
oil, mud, or glass grinding or polishing wastes.
3. Any wastewater having a pH less than 5.0, or higher than 9.0, unless
the POTW is specifically designed to accommodate such wastewater,
or wastewater having any other corrosive property capable of causing
damage or hazard to structures, equipment, and/or personnel of the
POTW.
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 POTW, or to exceed the limitations set forth in a Categorical
Pretreatment Standard. A toxic pollutant shall include but not be
limited to any pollutant identified pursuant to § 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 POTW's effluent or any other product
of the POTW such as residues, sludges, or scums, to be unsuitable
for reclamation and reuse or to interfere with the reclamation process.
In no case shall a substance discharged to the POTW cause the POTW
to be in non-compliance with sludge use or disposal criteria, guidelines
or regulations developed under § 405 of the Act; 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 POTW to violate its NPDES and/or
State Disposal System Permit or the receiving water quality standards.
8. Any wastewater with objectionable color not removed in the treatment
process, such as, but not limited to, dye wastes and vegetable tanning
solutions.
9. Any wastewater having a temperature which will inhibit biological
activity in the POTW treatment plant resulting in Interference, but
in no case wastewater with a temperature at the introduction into
the POTW which exceeds 40° C. (104° F.) unless the POTW treatment
plant is designed to accommodate such temperature.
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 to the POTW. 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 twenty-four-hour
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
Authority Manager in compliance with applicable State or Federal regulations.
12. Any wastewater which causes a hazard to human life or creates a public
nuisance. When the Authority Manager 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 Authority
Manager shall: (1) advise the user(s) of the impact of the contribution
on the POTW; and (2) develop effluent limitation(s) for such user
to correct the interference with the POTW.
[Ord. 160, 6/7/1988, § 502.2; as amended by Ord.
318, 5/29/2007]
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 for sources
in that subcategory, shall immediately supersede the limitations imposed
under this Part. The Authority Manager shall notify all affected users
of the applicable reporting requirements under 40 CFR, § 403.12.
[Ord. 160, 6/7/1988, § 502.3]
Where the CHJA's wastewater treatment system achieves consistent
removal of pollutants limited by Federal Pretreatment Standards, the
CHJA may apply to the Approval Authority for modification of specific
limits in the Federal Pretreatment Standards. "Consistent Removal"
shall mean reduction in the amount of the 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 95% of the samples taken when measured according to
the procedures set forth in § 403.7(c) of (Title 40 of the
Code Federal Regulations, Part 403) — "General Pretreatment
Regulations for Existing and New Sources of Pollution" promulgated
pursuant to the Act. The CHJA may then modify pollutant discharge
limits in the Federal Pretreatment Standards if the requirements contained
in 40 CFR, Part 403, § 403.7, are fulfilled and prior approval
from the approval authority is obtained.
[Ord. 160, 6/7/1988, § 502.4; as amended by Ord.

State requirements and limitations on discharges shall apply
in any case where they are more stringent than Federal requirements
and limitation or those in this Part.
[Ord. 160, 6/7/1988, § 502.6]
The CHJA reserves the right to establish by regulation more
stringent limitations or requirements on discharges to the wastewater
disposal system if deemed necessary to comply with the objectives
presented in § 5011.1 of this Part.
[Ord. 160, 6/7/1988, § 502.7]
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 CHJA or State.
[Ord. 160, 6/7/1988, § 502.8; as amended by Ord.
318, 5/29/2007]
1. Each user shall provide protection for accidental discharge of prohibited
materials or other substances regulated by this Part. Facilities to
prevent accidental discharge of prohibited materials shall be provided
and maintained at the owner or user's own cost and expense. Detailed
plans showing facilities and operating procedures to provide this
protection shall be submitted to the CHJA for review and shall be
approved by the CHJA before construction of the facility. All existing
users shall complete such a plan within one year of the effective
date of this Part. No user who commences contribution to the POTW
after the effective date of this Part shall be permitted to introduce
pollutants into the system until accidental discharge procedures have
been approved by the CHJA. 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 the Part. In the case of an accidental discharge, it is the responsibility
of the user to immediately telephone and notify the POTW of the incident.
The notification shall include location of discharge, type of waste,
concentration and volume, and corrective actions.
2. Written Notice. Within five days following an accidental discharge,
the user shall submit to the Authority Manager 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 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 or other applicable law.
3. Notice to Employees. 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 insure
that all employees who may cause or suffer such a dangerous discharge
to occur are advised of the emergency notification procedure.
