National Categorical Pretreatment Standards.
1. 
Users must comply with the categorical pretreatment standards found at 40 CFR Chapter I, Subchapter N, Parts 405 through 471.
a. 
Where a categorical pretreatment standard is expressed only in terms of either the mass or the concentration of a pollutant in wastewater, the Public Works Director or his/her duly authorized representative may impose equivalent concentration or mass limits.
b. 
When wastewater subject to a categorical pretreatment standard is mixed with wastewater not regulated by the same standard, the Public Works Director or shall impose an alternate limit in accordance with 40 CFR 403.6(e).
c. 
When a categorical pretreatment standard is expressed only in terms of pollutant concentrations, an industrial user may request that the City convert the limits to equivalent mass limits. The determination to convert concentration limits to mass limits is within the discretion of the Public Works Director or his/her duly authorized representative. The City may establish equivalent mass limits only if the industrial user meets all the condition set forth below.
(1) 
To be eligible for equivalent mass limits, the industrial user must:
(a) 
Currently use control and treatment technologies adequate to achieve compliance with the applicable categorical pretreatment standard, and not have used dilution as a substitute for treatment;
(b) 
Provide sufficient information to establish the facilities actual average daily flow rate for all waste streams, based on data from a continuous effluent flow monitoring device, as well as the facility's long-term average production rate. Both the actual average daily flow rate and the long-term average production rate must be representative of current operating conditions;
(c) 
Not have daily flow rates, production levels, or pollutant levels that vary so significantly that equivalent mass limits are not appropriate to control the discharge; and
(d) 
Have consistently complied with all applicable categorical pretreatment standards during the period prior to the industrial user's request for equivalent mass limits.
(2) 
An industrial user subject to equivalent mass limits must:
(a) 
Maintain and effectively operate control and treatment technologies adequate to achieve compliance with the equivalent mass limits;
(b) 
Continue to record the facility's flow rates through the use of a continuous effluent flow monitoring device.
(3) 
When developing equivalent mass limits, the Public Works Director or his/her duly authorized representative:
(a) 
Will calculate the equivalent mass limit by multiplying the actual average daily flow rate of the regulated process(es) of the industrial user by the concentration-based daily maximum and monthly average standard for the applicable categorical pretreatment standard and the appropriate unit conversion factor;
(b) 
May retain the same equivalent mass limit in subsequent individual wastewater discharger permit terms if the industrial user's actual average daily flow rate was reduced solely as a result of the implementation of water conservation methods and technologies, and the actual average daily flow rates used in the original calculation of the equivalent mass limit were not based on the use of dilution as a substitute for treatment pursuant to Section 720.020(D). The industrial user must also be in compliance with Section 720.140(C)(4) regarding the prohibition of bypass.
d. 
Once included in its permit, the industrial user must comply with the equivalent limitations developed in this Section 720.020(B) in lieu of the promulgated categorical standards from which the equivalent limitations were derived.
C. 
State Pretreatment Standards. State of Missouri requirements and limitations on discharges pursuant to this Section shall apply when they are more stringent than the United States Environmental Protection Agency requirements and limitations, unless allowed by the Missouri Department of Natural Resources. Missouri State pretreatment standards are codified at 10 CSR 20-6.100.
D. 
Local Limits.
1. 
The Public Works Director is authorized to establish local limits pursuant to 40 CFR 403.5(c). Maximum allowable industrial loads shown in Section 720.020(A)(3) are incorporated into this Chapter in lieu of local limits.
2. 
Public Works Director may develop best management practices (BMPs), by ordinance or in individual wastewater discharge permits, to implement local limits and the requirements of Section 720.020.
E. 
City's Right Of Revision. The City reserves the right to establish, by ordinance or in individual wastewater discharge permits, more stringent standards or requirements on discharges to the POTW consistent with the purpose of this Chapter.
F. 
Dilution. 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 Public Works Director or his/her duly authorized representative 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.

For all other users subject to categorical pretreatment standards expressed in terms of allowable pollutant discharge per unit of production (or other measure of operation), this report shall include the user's actual production during the appropriate sampling period. All compliance reports must be signed and certified in accordance with Section 720.060(N)(1) of this Chapter. All sampling will be done in conformance with Section 720.060(K).
D. 
Periodic Compliance Reports.
1. 
Except as specified in Section 720.060(D)(3), all significant industrial users must, at a frequency determined by the Public Works Director or his/her duly authorized representative submit no less than twice per year June and December reports or as otherwise required by the Public Works Department indicating the nature, concentration of pollutants in the discharge which are limited by pretreatment standards and the measured or estimated average and maximum daily flows for the reporting period. In cases where the pretreatment standard requires compliance with a best management practice (BMP) or pollution prevention alternative, the user must submit documentation required by the Public Works Director or his/her duly authorized representative or the pretreatment standard necessary to determine the compliance status of the user.
2. 
The City may authorize an industrial user subject to a categorical pretreatment standard to forego sampling of a pollutant regulated by a categorical pretreatment standard if the industrial user has demonstrated through sampling and other technical factors that the pollutant is neither present nor expected to be present in the discharge, or is present only at background levels from intake water and without any increase in the pollutant due to activities of the industrial user. [See 40 CFR 403.12(e)(2).] This authorization is subject to the following conditions:
a. 
The waiver may be authorized where a pollutant is determined to be present solely due to sanitary wastewater discharged from the facility provided that the sanitary wastewater is not regulated by an applicable categorical standard and otherwise includes no process wastewater.
b. 
The monitoring waiver is valid only for the duration of the effective period of the individual wastewater discharge permit, but in no case longer than five (5) years. The user must submit a new request for the waiver before the waiver can be granted for each subsequent individual wastewater discharge permit. See Section 720.040(E)(1)(h).
c. 
In making a demonstration that a pollutant is not present, the industrial user must provide data from at least one (1) sampling of the facility's process wastewater prior to any treatment present at the facility that is representative of all wastewater from all processes.
d. 
The request for a monitoring waiver must be signed in accordance with the definition of "authorized or duly authorized representative of the user" in Section 720.010(D), and include the certification statement in Section 720.060(N)(1) [40 CFR 403.6(a)(2)(ii)].
e. 
Non-detectable sample results may be used only as a demonstration that a pollutant is not present if the EPA approved method from 40 CFR 136 with the lowest minimum detection level for that pollutant was used in the analysis.
f. 
Any grant of the monitoring waiver by the Public Works Director must be included as a condition in the user's permit. The reasons supporting the waiver and any information submitted by the user in its request for the waiver must be maintained by the Public Works Director for three (3) years after expiration of the waiver.
g. 
Upon approval of the monitoring waiver and revision of the user's permit by the Public Works Director, the industrial user must certify on each report with the statement in Section 720.060(N)(3) below, that there has been no increase in the pollutant in its waste stream due to activities of the industrial user.
h. 
In the event that a waived pollutant is found to be present or is expected to be present because of changes that occur in the user's operations, the user must immediately: Comply with the monitoring requirements of Section 720.060(D)(1), or other more frequent monitoring requirements imposed by the Public Works Director, and notify the Public Works Director.
i. 
This provision does not supersede certification processes and requirements established in categorical pretreatment standards, except as otherwise specified in the categorical pretreatment standard.
3. 
All periodic compliance reports must be signed and certified in accordance with Section 720.060(N)(1) of this Chapter.
4. 
All wastewater samples must be representative of the user's discharge. Wastewater monitoring and flow measurement facilities shall be properly operated, kept clean, and maintained in good working order at all times. The failure of a user to keep its monitoring facility in good working order shall not be grounds for the user to claim that sample results are unrepresentative of its discharge.
5. 
If a user subject to the reporting requirement in this Section monitors any regulated pollutant at the appropriate sampling location more frequently than required by the Public Works Director or his/her duly authorized representative, using the procedures prescribed in Section 702.060(K) of this Chapter, the results of this monitoring shall be included in the report.
E. 
Reports Of Changed Conditions. Each user must notify the Public Works Director or his/her duly authorized representative of any significant changes to the user's operations or system which might alter the nature, quality, or volume of its wastewater at least ninety (90) days before the change.
1. 
The Public Works Director or his/her duly authorized representative may require the user to submit such information as may be deemed necessary to evaluate the changed condition, including the submission of a wastewater discharge permit application under Section 720.040 of this Chapter.
2. 
The Public Works Director or his/her duly authorized representative may issue an individual wastewater discharge permit under Section 720.050(C) of this Chapter or modify an existing wastewater discharge permit under Section 720.050(D) of this Chapter in response to changed conditions or anticipated changed conditions.
F. 
Reports Of Potential Problems.
1. 
In the case of any discharge, including, but not limited to, accidental discharges, discharges of a non-routine, episodic nature, a non-customary batch discharge, a slug discharge or slug load, that might cause potential problems for the POTW, the user shall immediately telephone and notify the Public Works Director or his/her duly authorized representative of the incident. This notification shall include the location of the discharge, type of waste, concentration and volume, if known, and corrective actions taken by the user.
2. 
Within five (5) days following such discharge, the user shall, unless waived by the Public Works Director or his/her duly authorized representative, submit a detailed written report describing the cause(s) 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 might be incurred as a result of damage to the POTW, natural resources, or any other damage to person or property; nor shall such notification relieve the user of any fines, penalties, or other liability which may be imposed pursuant to this Chapter.
3. 
A notice shall be permanently posted on the user's bulletin board or other prominent place advising employees who to call in the event of a discharge described in Subsection (F)(1), above. Employers shall ensure that all employees, who could cause such a discharge to occur, are advised of the emergency notification procedure.
4. 
Significant industrial users are required to notify the Public Works Director or his/her duly authorized representative immediately of any changes at its facility affecting the potential for a slug discharge.
G. 
Reports From Unpermitted Users. All users not required to obtain an individual wastewater discharge permit shall provide appropriate reports to the Public Works Director or designee as the Public Works Director or his/her duly authorized representative may require.
H. 
Notice Of Violation/Repeat Sampling And Reporting. If sampling performed by a user indicates a violation, the user must notify the Public Works Director or his/her duly authorized representative within twenty-four (24) hours of becoming aware of the violation. The user shall also repeat the sampling and analysis and submit the results of the repeat analysis to the Public Works Director or his/her duly authorized representative within thirty (30) days after becoming aware of the violation. Resampling by the industrial user is not required if the City performs sampling at the user's facility at least once a month, or if the City performs sampling at the user between the time when the initial sampling was conducted and the time when the user or the City receives the results of this sampling, or if the City has performed the sampling and analysis in lieu of the industrial user.
I. 
Notification Of The Discharge Of Hazardous Waste.
1. 
Prohibited. The City does not allow the discharge of hazardous waste into the POTW as defined in "septic tank waste" in Section 720.010(D).
J. 
Analytical Requirements. All pollutant analyses, including sampling techniques, to be submitted as part of a wastewater discharge permit application or report shall be performed in accordance with the techniques prescribed in 40 CFR 136 and amendments thereto, unless otherwise specified in an applicable categorical pretreatment standard. If 40 CFR 136 does not contain sampling or analytical techniques for the pollutant in question, or where the EPA determines that the Part 136 sampling and analytical techniques are inappropriate for the pollutant in question, sampling and analyses shall be performed by using validated analytical methods or any other applicable sampling and analytical procedures, including procedures suggested by the Public Works Director or designee or other parties approved by EPA.
K. 
Sample Collection. Samples collected to satisfy reporting requirements must be based on data obtained through appropriate sampling and analysis performed during the period covered by the report, based on data that is representative of conditions occurring during the reporting period.
1. 
Except as indicated in Subsection (K)(2) and (3) below, the user must collect wastewater samples using twenty-four-hour flow-proportional composite sampling techniques, unless time-proportional composite sampling or grab sampling is authorized by the Public Works Director or his/her duly authorized representative. Where time-proportional composite sampling or grab sampling is authorized by the City, the samples must be representative of the discharge. Using protocols (including appropriate preservation) specified in 40 CFR 136 and appropriate EPA guidance, multiple grab samples collected during a twenty-four-hour period may be composited prior to the analysis as follows: for cyanide, total phenols, and sulfides the samples may be composited in the laboratory or in the field; for volatile organics and oil and grease, the samples may be composited in the laboratory. Composite samples for other parameters unaffected by the compositing procedures as documented in approved EPA methodologies may be authorized by the City, as appropriate. In addition, grab samples may be required to show compliance with instantaneous limits.
2. 
Samples for oil and grease, temperature, pH, cyanide, total phenols, sulfides, ammonia and volatile organic compounds must be obtained using grab collection techniques.
3. 
For sampling required in support of baseline monitoring and ninety-day compliance reports required in Section 720.060(A) and 720.060(C) [40 CFR 403.12(b) and (d)], a minimum of four (4) grab samples must be used for pH, cyanide, total phenols, oil and grease, sulfide and volatile organic compounds for facilities for which historical sampling data do not exist; for facilities for which historical sampling data are available, the Public Works Director his/her duly authorized representative may authorize a lower minimum. For the reports required by Section 720.060 [40 CFR 403.12(e) and 403.12(h)], the industrial user is required to collect the number of grab samples necessary to assess and assure compliance by with applicable pretreatment standards and requirements.

Further, the Public Works Director or designee is empowered to take more than one (1) enforcement action against any non-compliant user.
[Ord. No. 13.112, 9-22-2020]
A. 
Performance Bonds. The Public Works Director or his/her duly authorized representative may decline to issue or reissue an individual wastewater discharge permit to any user who has failed to comply with any provision of this Chapter, a previous individual wastewater discharge permit or order issued hereunder, or any other pretreatment standard or requirement, unless such user first files a satisfactory bond, payable to the City, in a sum not to exceed a value determined by the Public Works Director or his/her duly authorized representative to be necessary to achieve consistent compliance.
B. 
Liability Insurance. The Public Works Director or his/her duly authorized representative may decline to issue or reissue an individual wastewater discharge to any user who has failed to comply with any provision of this Chapter, a previous individual wastewater discharge permit, or order issued hereunder, or any other pretreatment standard or requirement, unless the user first submits proof that it has obtained financial assurances sufficient to restore or repair damage to the POTW caused by its discharge.
C. 
Payment Of Outstanding Fees And Penalties. The Public Works Director or his/her duly authorized representative may decline to issue or reissue an individual wastewater discharge permit to any user who has failed to pay any outstanding fees, fines or penalties incurred as a result of any provision of this Chapter, a previous individual wastewater discharge permit or order issued hereunder.
D. 
Water Supply Severance. Whenever a user has violated or continues to violate any provision of this Chapter, an individual wastewater discharge permit, or order issued hereunder, or any other pretreatment standard or requirement, water service to the user may be severed. Service will recommence, at the user's expense, only after the user has satisfactorily demonstrated its ability to comply.
E. 
Public Nuisances. A violation of any provision of this Chapter, an individual wastewater discharge permit, or order issued hereunder, or any other pretreatment standard or requirement is hereby declared a public nuisance and shall be corrected or abated as directed by the Public Works Director or his/her duly authorized representative. Any person(s) creating a public nuisance shall be subject to the provisions of the City Code Chapter 215, Nuisances, Section 215.010, governing such nuisances, including reimbursing the City for any costs incurred in removing, abating, or remedying said nuisance.
F. 
Contractor Listing. Users which have not achieved compliance with applicable pretreatment standards and requirements are not eligible to receive a contractual award for the sale of goods or services to the City. Existing contracts for the sale of goods or services to the City held by a user found to be in significant non-compliance with pretreatment standards or requirements may be terminated at the discretion of the Public Works Director or his/her duly authorized representative.
[Ord. No. 13.112, 9-22-2020]
A. 
Upset.
1. 
For the purposes of this Section, upset means an exceptional incident in which there is unintentional and temporary non-compliance with categorical pretreatment standards because of factors beyond the reasonable control of the user. An upset does not include non-compliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation.
2. 
An upset shall constitute an affirmative defense to an action brought for non-compliance with categorical pretreatment standards if the requirements of Subsection (A)(3), below, are met.
3. 
A user who wishes to establish the affirmative defense of upset shall demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that:
a. 
An upset occurred and the user can identify the cause(s) of the upset;
b. 
The facility was at the time being operated in a prudent and workmanlike manner and in compliance with applicable operation and maintenance procedures; and
c. 
The user has submitted the following information to the Public Works Director or his/her duly authorized representative within twenty-four (24) hours of becoming aware of the upset [if this information is provided orally, a written submission must be provided within five (5) days];
d. 
A description of the indirect discharge and cause of non-compliance;
e. 
The period of non-compliance, including exact dates and times or, if not corrected, the anticipated time the non-compliance is expected to continue; and
f. 
Steps being taken and/or planned to reduce, eliminate, and prevent recurrence of the non-compliance.
4. 
In any enforcement proceeding, the user seeking to establish the occurrence of an upset shall have the burden of proof.
5. 
Users shall have the opportunity for a judicial determination on any claim of upset only in an enforcement action brought for non-compliance with categorical pretreatment standards.
6. 
Users shall control production of all discharges to the extent necessary to maintain compliance with categorical pretreatment standards upon reduction, loss, or failure of its treatment facility until the facility is restored or an alternative method of treatment is provided. This requirement applies in the situation where, among other things, the primary source of power of the treatment facility is reduced, lost, or fails.
B. 
Prohibited Discharge Standards. A user shall have an affirmative defense to an enforcement action brought against it for non-compliance with the general prohibitions in Section 720.020(A)(1) of this Chapter or the specific prohibitions in Sections 720.020(A)(2)(a) through (h) of this Chapter if it can prove that it did not know, or have reason to know, that its discharge, alone or in conjunction with discharges from other sources, would cause pass-through or interference and that either:
1. 
A local limit exists for each pollutant discharged and the user was in compliance with each limit directly prior to, and during, the pass-through or interference; or
2. 
No local limit exists, but the discharge did not change substantially in nature or constituents from the user's prior discharge when the City was regularly in compliance with its NPDES permit, and in the case of interference, was in compliance with applicable sludge use or disposal requirements.
C. 
Bypass.
1. 
For the purposes of this Section:
a. 
Bypass means the intentional diversion of waste streams from any portion of a user's treatment facility.
b. 
Severe property damage means substantial physical damage to property, damage to the treatment facilities which causes them to become inoperable, or substantial and permanent loss of natural resources which can reasonably be expected to occur in the absence of a bypass. Severe property damage does not mean economic loss caused by delays in production.
2. 
A user may allow any bypass to occur which does not cause pretreatment standards or requirements to be violated, but only if it also is for essential maintenance to assure efficient operation. These bypasses are not subject to the provision of Subsection (C)(3) and (4) of this Section.
3. 
Bypass Notifications.
a. 
If a user knows in advance of the need for a bypass, it shall submit prior notice to the Public Works Director or his/her duly authorized representative, at least ten (10) days before the date of the bypass, if possible.
b. 
A user shall submit oral notice to the Public Works Director or his/her duly authorized representative of an unanticipated bypass that exceeds applicable pretreatment standards within twenty-four (24) hours from the time it becomes aware of the bypass. A written submission shall also be provided within five (5) days of the time the user becomes aware of the bypass. The written submission shall contain a description of the bypass and its cause; the duration of the bypass, including exact dates and times, and, if the bypass has not been corrected, the anticipated time it is expected to continue; and steps taken or planned to reduce, eliminate, and prevent reoccurrence of the bypass. The Public Works Director or his/her duly authorized representative may waive the written report on a case-by-case basis if the oral report has been received within twenty-four (24) hours.
4. 
Bypass Prohibited; Exceptions.
a. 
Bypass is prohibited, and the Public Works Director or his/her duly authorized representative may take an enforcement action against a user for a bypass, unless:
(1) 
Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage;
(2) 
There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes, or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate back-up equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass which occurred during normal periods of equipment downtime or preventive maintenance; and
(3) 
The user submitted notices as required under Subsection (C)(3) of this Section.
b. 
The Public Works Director or designee may approve an anticipated bypass, after considering its adverse effects, if the Public Works Director or his/her duly authorized representative determines that it will meet the three (3) conditions listed in Subsection (C)(4)(a) of this Section.
[Ord. No. 13.112, 9-22-2020]
A. 
Pretreatment Charges And Fees. The City may adopt reasonable fees for reimbursement of costs of setting up and operating the City's pretreatment program, which may include:
