[R.O. 2014 §710.040; Ord. No. 414 §2.1, 9-25-1980; Ord. No. 574 §2.1, 5-10-1990; Ord. No. 1977, 1-14-2021]
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 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 (2) successive readings on an explosion hazard meter, at
the point in the system be more than five percent (5%) nor any single
reading over ten percent (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
City, 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 one-half (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 five (5.0), 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, constitutes a hazard
to humans or animals, creates 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 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 their 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 where the POTW is pursuing a reuse and reclamation program.
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 Section 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 forty degrees centigrade (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 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 fifteen (15) minutes more than five (5) times the average twenty-four
(24) 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 Superintendent 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 Superintendent 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 Superintendent
shall:
[R.O. 2014 §710.050; Ord. No. 414 §2.2, 9-25-1980; Ord. No. 574 §2.2, 5-10-1990; Ord. No. 1977, 1-14-2021]
Upon the promulgation of the Federal Categorical Pretreatment
Standard for a particular industrial subcategory, the Federal standard,
if more stringent than limitations imposed by or under this Chapter
for sources in that subcategory, shall immediately supersede the limitations
imposed under this Chapter. The Superintendent shall notify all affected
users of the applicable reporting requirements under 40 CFR, Section
403.12.
[R.O. 2014 §710.060; Ord. No. 414 §2.3, 9-25-1980; Ord. No. 574 §2.3, 5-10-1990; Ord. No. 1977, 1-14-2021]
Where the City's wastewater treatment system achieves consistent
removal of pollutants limited by Federal pretreatment standards, the
City 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 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 ninety-five percent (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, Part 403) "General
Pretreatment Regulations for Existing and New Sources of Pollution"
promulgated pursuant to the Act. The City may modify pollutant discharge
limits in the Federal pretreatment standards if the requirements contained
in 40 CFR, Part 403, Section 403.7, are fulfilled and prior approval
from the approval authority is obtained.
[R.O. 2014 §710.070; Ord. No. 414 §2.4, 9-25-1980; Ord. No. 574 §2.4, 5-10-1990; Ord. No. 1977, 1-14-2021]
A.
The following local limits have been developed pursuant to 40 CFR
Section 403.5(c) to prevent against interference and pass through.
B.
The local limits expressed in pounds per day shall be distributed
at the discretion of the pretreatment director via pretreatment program
permits to each significant industrial user, as necessary. The sum
of each permitted local limit shall not exceed the mass in the table
below, Table 1, Local Limits. At the discretion of the Pretreatment
Director, the limits established in pretreatment permits may be imposed
as pollutant concentrations using appropriate conversion methods.
C.
All values for metallic pollutants are for total metal unless otherwise
indicated.
D.
Pretreatment Director may develop best management practices (BMPs), by ordinance or in individual pretreatment program permits as local limits to implement the requirements of Section 710.070, Specific Pollutant Limitations (Local Limits).
E.
Local limits are subject to change as local environmental conditions
change. All changes to local limits shall be approved by the Missouri
Department of Natural Resources. Refer to the Enforcement Response
Plan (ERP) for guidance on all phases of enforcement related to the
City's Pretreatment Program.

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 Chapter.
[R.O. 2014 §710.090; Ord. No. 414 §2.6, 9-25-1980; Ord. No. 574 §2.6, 5-10-1990; Ord. No. 1977, 1-14-2021]
The City 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 in Section 710.010 of this Chapter.
[R.O. 2014 §710.100; Ord. No. 414 §2.7, 9-25-1980; Ord. No. 574 §2.7, 5-10-1990; Ord. No. 1977, 1-14-2021]
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 City or State. (Comment: Dilution may be an acceptable means of complying with some of the prohibitions set forth in Section 710.040, et seq., the pH prohibition.)
[R.O. 2014 §710.110; Ord. No. 414 §2.8, 9-25-1980; Ord. No. 574 §2.8, 5-10-1990; Ord. No. 1977, 1-14-2021]
A.
Each user shall provide protection from accidental discharge of prohibited
materials or other substances regulated by this Chapter. 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 City for review, and shall be
approved by the City before construction of the facility. All existing
users shall complete such a plan by January 1, 1983. No user who commences
contribution to the POTW after September 25, 1980, shall be permitted
to introduce pollutants into the system until accidental discharge
procedures have been approved by the City. 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 Chapter. 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.
B.
Written Notice. Within five (5) days following an accidental discharge,
the user shall submit to the Superintendent 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 Article 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.
D.
Significant industrial users are required to notify the Superintendent
immediately of any changes at its facility, including changes affecting
the potential for a slug discharge.
[Ord. No. 1977, 1-14-2021]
A.
Any user who commences the discharge of hazardous waste shall notify the POTW, the EPA Regional Waste Management Division Director, and State hazardous waste authorities, in writing, of any discharge into the POTW of a substance which, if otherwise disposed of, would be a hazardous waste under 40 CFR Part 261. Such notification must include the name of the hazardous waste as set forth in 40 CFR Part 261, the EPA hazardous waste number, and the type of discharge (continuous, batch, or other). If the user discharges more than one hundred (100) kilograms of such waste per calendar month to the POTW, the notification also shall contain the following information to the extent such information is known and readily available to the user: an identification of the hazardous constituents contained in the wastes, an estimation of the mass and concentration of such constituents in the wastestream discharged during that calendar month, and an estimation of the mass of constituents in the wastestream expected to be discharged during the following twelve (12) months. All notifications must take place no later than one hundred eighty (180) days after the discharge commences. Any notification under this paragraph need be submitted only once for each hazardous waste discharged. However, notifications of changed conditions must be submitted under Section 710.100(D) of this Chapter. The notification requirement in this Section does not apply to pollutants already reported by users subject to categorical pretreatment standards under the self-monitoring requirements of Section 710.160 of this Chapter.
B.
Dischargers are exempt from the requirements of Subsection (A), above, during a calendar month in which they discharge no more than fifteen (15) kilograms of hazardous wastes, unless the wastes are acute hazardous wastes as specified in 40 CFR Sections 261.30(d) and 261.33(e). Discharge of more than fifteen (15) kilograms of non-acute hazardous wastes in a calendar month, or of any quantity of acute hazardous wastes as specified in 40 CFR Sections 261.30(d) and 261.33(e), requires a one-time notification. Subsequent months during which the user discharges more than such quantities of any hazardous waste do not require additional notification.
C.
In the case of any new regulations under Section 3001 of RCRA identifying
additional characteristics of hazardous waste or listing any additional
substance as a hazardous waste, the user must notify the Superintendent,
the EPA Regional Waste Management Waste Division Director, and State
hazardous waste authorities of the discharge of such substance within
ninety (90) days of the effective date of such regulations.
D.
In the case of any notification made under this Section, the user
shall certify that it has a program in place to reduce the volume
and toxicity of hazardous wastes generated to the degree it has determined
to be economically practical.
E.
This provision does not create a right to discharge any substance
not otherwise permitted to be discharged by this Chapter, a permit
issued thereunder, or any applicable Federal or State law.
