MEMORANDUM
TO: Honorable Mayor and Members of the Common Council
FROM: Stephan M. Brand, Public Works Utility Bureau Manager�5o6
DATE: October 18, 2018
RE: Repeal and Recreate Chapter 24 / Wastewater Systems
BACKGROUND
The Wisconsin Department of Natural Resources (WDNR), through an agreement with the United States
Environmental Protection Agency (EPA), is responsible for permitting and setting regulatory requirements
for municipal wastewater treatment systems. These requirements are completed through the issuance of
system -specific Wisconsin Pollutant Discharge Elimination System (WPDES) permits. One of the required
elements of the WPDES Permit for communities with a treatment plant flow of over five million gallons per
day is to have an Industrial Pre -Treatment Program. The City of Oshkosh implements these requirements
within Chapter 24 of the Municipal Code of the City of Oshkosh.
In 2014, the WDNR updated its program to reflect updates and changes made by the EPA. The WDNR
provided information on the program changes to communities so the communities could have these new
requirements included within their local ordinances. Prior to implementing those revisions, the Wastewater
Utility completed a local limits study to determine if any changes were necessary to the treatment
requirements for industries regulated by the pre-treatment program. Sampling was completed in 2016, and
the final report was issued in 2017. The revised program was submitted to the WDNR for their review and
was approved in February 2018. These updates to Chapter 24 include the WDNR-approved revisions to the
City's program.
ANALYSIS
Wastewater Utility staff worked with the City Attorney's office to incorporate the revisions necessary to be
consistent with the WDNR-approved program, along with editorial changes to improve clarity. No local
limits were changed or added, with the exception of adding an upper limit for pH to 12.0 standard units.
FISCAL IMPACT
There are no budgetary impacts associated with these changes.
RECOMMENDATIONS
I recommend approval of the proposed revisions to Chapter 24 of the Municipal Code of the City of Oshkosh.
Approved,
Mark A. Rohloff
City Manager

and have in operating condition, and shall "startup" all pollution control equipment required to
meet applicable Pretreatment Standards before beginning to discharge. Within the shortest
feasible time (not to exceed ninety [90] days), New Sources must meet all applicable Categorical
Pretreatment Standards.
(1) When the limits in a Categorical Pretreatment Standard are expressed only in terms of
mass of pollutant per unit of production, the Control Authority may convert the limits to
equivalent limitations expressed as mass of pollutant discharged per day or effluent
concentration for purposes of calculating effluent limitations applicable to individual
Industrial Users. (Interpretations of this subparagraph shall conform to 40 CFR 403.6(c)
General Pretreatment Regulations.)
(E) State Requirements
State of Wisconsin requirements and limitations on discharges to the Wastewater System shall
be met by all industries which are subject to such standards in any instance in which these
requirements and limitations are more stringent than Federal requirements and those in this or
any other applicable ordinance.
(F) Enforcement
If any waters or wastes are discharged, or proposed to be discharged to the Wastewater System,
that contain substances or possess the characteristics enumerated in Section 24-6.2, or that do not
meet the requirements and limitations of applicable Federal Categorical Pretreatment Standards,
or that do not meet State requirements and limitations on discharge to the Wastewater System, or
that in the judgment of the Control Authority, may have deleterious effects upon the wastewater
system, processes, equipment, or receiving waters, or that otherwise create a hazard to life or
health, or constitute a public nuisance, the Control Authority may:
(6)
(7)
(8)
(9)
Reject the wastes.
Require either self-monitoring, or compliance monitoring in accordance with a schedule
and by methods determined by the Control Authority.
Require pretreatment to an acceptable condition for discharge to the Public Sewers.
Require control over the quantities and rates of discharge.
Require payment to cover the added cost of monitoring, handling and treating the wastes
not covered by existing Sewer charges, under the provisions of Section 24-6.5.
Revoke the Wastewater Discharge Permit.
Publish instances of significant noncompliance by Users.
Issue administrative orders and fines.
Seek civil action, including injunctive relief.

hauling of the collected materials not performed by owner(s) personnel must be performed by
currently licensed waste disposal firms. This Section shall pertain to, but is not limited to, all
businesses identified as Food Service Establishments (FSEs) by the Control Authority.
(H) Dilution
Except where expressly authorized to do so by an applicable Pretreatment Standard or
requirement, no Discharger shall use potable water, Unpolluted Water, cooling water or
process water in any way, nor mix separate waste streams, for the purpose of diluting a
discharge as a partial or complete substitute for adequate treatment to achieve compliance
with the standards set forth in this Ordinance. The City may impose mass limitations on
Industrial Users which are using dilution to meet applicable Pretreatment Standards or
requirements or in other cases where the imposition of mass limitations is appropriate.
(1) Accidental Discharges
All Persons, commercial establishments and industries shall provide protection from
accidental discharge or the introduction of prohibited or regulated materials or substances
established by this Ordinance. Where necessary, facilities to prevent accidental discharge
or the introduction of prohibited materials shall be provided and maintained at the potential
Discharger's cost and expense. When requested by the Control Authority, detailed plans

composite samples must be obtained through flow -proportioned sampling
techniques where feasible. The Control Authority may waive flow -proportional
composite sampling for any Industrial User that demonstrates that flow -proportion
sampling is infeasible. In such cases samples may be obtained through time -
proportional composite sampling techniques or through a minimum of four (4) grab
samples where the User demonstrates that this will provide a representative
sample of the effluent being discharged.
(c) The User shall take a minimum of one representative sample to compile that data
necessary to comply with the requirements of this paragraph.
(d) Samples should be taken immediately downstream from pretreatment facilities
if such exist or immediately downstream from the regulated process if no
pretreatment exists. If other wastewaters are mixed with the regulated wastewater
prior to pretreatment the User should measure the flows and concentrations
necessary to allow use of the combined waste stream formula of Section
403.61(e) in order to evaluate compliance with the Pretreatment Standards.
Where an alternate concentration of mass limit has been calculated in accordance
with Section 403.6(e) this adjusted limit along with supporting data shall be
submitted to the POTW.
(6) The Industrial User shall provide a statement, reviewed by an authorized representative
of the Industrial User and certified by a qualified professional, indicating whether National
Categorical Pretreatment Standards are being met on a consistent basis and, if not, whether
additional operation and maintenance measures (O&M) or additional pretreatment is
required for the Industrial User to meet the National categorical Pretreatment Standards.
(7) Similarly, each Industrial User desiring to make a new connection to the system, or
modifying an existing process or connection to the system, shall be required to file with
the Authority, a revised Industrial Wastewater Discharge Application, and baseline report,
and obtain a new wastewater discharge permit, if applicable, or modify the existing
discharge permit before connecting to the Wastewater System.
(B) Submission of Federal Categorical Pretreatment Standards Data

unless the industry specifically requests and is able to demonstrate to the satisfaction of the
Authority that the release of such information would divulge information, processes or methods
of production entitled to protection as trade secrets or proprietary information of the Industry.
When requested by an industry furnishing a report, the portions of a report which may disclose
trade secrets or secret processes shall not be made available for inspection by the public
but shall be made available upon written request to governmental agencies for uses related
to this Ordinance, the National Pollutant Discharge Elimination System (NPDES) Permit,
WPDES permit and/or the Industrial Wastewater Programs; provided, however, that such
portions of a report shall be available for use by the State or any state agency injudicial review
of enforcement proceedings involving the Industry furnishing the report. Wastewater
constituents and characteristics will not be recognized as confidential information.
Pretreatment
Where required, in the opinion of the Control Authority, to modify or eliminate wastes that
interfere with the operation of the Wastewater System, or with the use or disposal of sludge,
or are harmful to the structures, Sewers, equipment, processes or operation of the Wastewater
treatment works or are otherwise incompatible with such works, or that pass through the
treatment works and adversely affect the receiving stream or the environment, or that will
endanger life, limb, public property, or constitute a nuisance, the Industrial User shall provide,
at the User's expense, such preliminary treatment or processing facilities as may be
determined to be required to render the industrial wastes acceptable for admission to the
Public Sewers.
(1) Compliance Report
Within 90 days following the date for final compliance by an industry with applicable
Pretreatment Standards or other Ordinance limitations, or in the case of a New
Source, within 90 days following commencement of the introduction of Wastewater
into the POTW, the Industrial User shall submit to the Authority a report containing the
information described in Sec. 24-6.3(A)(3)(4)(5) and (6). For Industrial Users subject to
equivalent mass or concentration limits established by the Control Authority with the
procedures in 40 C. F. R. 403.6(c), this report shall contain a reasonable measure of
the Industrial User's long term production rate. For all other Industrial 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 Industrial User's actual production during the appropriate sampling period.
(2) Compliance Schedule
(a) Compliance schedules shall contain milestone dates for the commencement
and completion of major events leading to the construction and operation of
additional pretreatment required for the industry to comply with the
requirements of this Ordinance, including, but not limited to, dates relating to
hiring an engineer, hiring other appropriate personnel, completing preliminary

to achieve compliance with this Ordinance.
(b) Under no circumstance shall any time increment for any single major event
directed toward compliance exceed nine (9) months.
(c) Not later than 14 days following each milestone date in the schedule and the
final date for compliance, the Industry shall submit a progress report to the City,
including no less than a statement as to whether or not it complied with the
increment of progress represented by that milestone date and, if not, the date
on which it expects to comply with this increment of progress, the reason for
delay, and the steps being taken by the industry to return the construction to
the approved schedule. In no event shall more than nine (9) months elapse
between such progress reports to the City.
(3) Periodic Compliance Reports
Any Industrial User subject to a Categorical Pretreatment Standard or other requirement
set forth in this Ordinance, after the compliance date of such standard or requirement, or,
in the case of a new industry, after commencement of the discharge to the Wastewater
System, shall allow the Control Authority quarterly, unless required more frequently by the
Authority, to monitor the nature and concentration of substances in the industrial effluent
which are limited by the Pretreatment Standards and/or other requirements hereof, and
which may be deemed to have significant impact on the POTW, its operation, maintenance
or personnel. The cost of any or such monitoring performed at the industry as directed
by the Control Authority shall be billed to the industry. The Control Authority may choose
to directly perform such monitoring or contract services of an engineering firm to conduct
the monitoring. Personnel from a contracted engineering firm shall be deemed Duly
Authorized Representatives of the Control Authority, and shall have the right of entry to
inspect, observe, and sample as provided for in Section 24-6.3(F) of the this Ordinance.
In addition, if required by the Authority, the industry shall submit a report to the Authority
by June 31st and December 31st of each year, or other dates as established that must
contain, but is not limited to, the following items:
(a) A record of all measured or estimated average and maximum daily flows from
designated points that occurred on the basis of actual measurement, provided,
however, where cost or feasibility considerations justify, the Control Authority may
accept reports of average and maximum flows estimated by verifiable techniques.
(b) Volumes and dates of discharge of all batch tank contents discharged to the Sanitary
Sewer during the reporting period and scheduled discharges during the next
reporting period.
(c) Certification statements, on forms provided by the Control Authority, as to the status
of hazardous wastes and/or toxic organics stored on the Industrial premises or
used in any of the industry's manufacturing processes and potentially discharged to
the Sewer system.
(d) The report shall be signed by an Authorized Representative of the Industrial User
City of Oshkosh Chapter 24 — Page 18 Municipal Code
City of Oshkosh
Municipal Code
Revised 7/3/18
as outlined under 40 CFR 403.12(1).
(e) If an Industrial User subject to the reporting requirement of this Section monitors
any pollutant more frequently than required by the Control Authority, the results
of this monitoring shall be included in the report.
(f) In cases where the Pretreatment Standard requires compliance with a Best
Management Practice (BMP) or pollution prevention alternative, the Industrial User
must submit documentation as required by the Control Authority or Pretreatment
Standard necessary to determine the compliance status of the Industrial User.
(F) Waste Sampling
All wastes discharged into the Public Sewers may be subject to periodic sampling, measurement
and analysis to determine the true nature, characteristics, constituents and concentration of said
wastes. The sampling, flow measuring and analysis may be done by the Control Authority at its
option, with all cost being billed to industry. All results, findings and reports shall be submitted
to the Control Authority within 30 days of sampling, unless required otherwise by the Control
Authority.
(1) Except as indicated in Section (2) and (3) below, the Industrial User must collect wastewater
samples using 24-hour flow -proportional composite sampling techniques, unless time -
proportional composite sampling or grab sampling is authorized by the Control Authority.
Where time -proportional composite sampling or grab sampling is authorized by the Control
Authority, the samples must be representative of the discharge and the decision to allow
alternative methods shall be documented in the Industrial User's file. Using protocols
(including appropriate preservation) specified in 40 CFR Part 136 and appropriate EPA
guidance, multiple grab samples collected during a 24-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 Control Authority, 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, and volatile
organic compounds must be obtained using grab collection techniques.
(3) For sampling required in support of baseline monitoring and 90 -day compliance reports
required in Section 24-6.3 (A)(5)(b) and 24-6.3 (E)(1), as well as 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 Control
Authority may authorize a lower minimum. For the reports required by Section 24-6.3 (E)(3)
and 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 with applicable Pretreatment
Standards and Requirements.
If the sampling performed by an Industrial User indicates a violation, the Industrial User
shall notify the Control Authority within 24 hours of becoming aware of the violation.
The Industrial User shall also repeat the sampling and analysis and submit the results of
the repeat analysis to the Control Authority within 30 days after becoming aware of the
City of Oshkosh Chapter 24 — Page 19 Municipal Code
City of Oshkosh
Municipal Code
Revised 7/3/18
violation, except the Industrial User is not required to resample if:
(a) The Control Authority performs sampling at the Industrial User at a frequency of at
least one per month, or
(b) The Control Authority performs sampling at the Industrial User between the time
when the Industrial User performs its initial sampling and the time when the
Industrial User receives the results of this sampling, or
(c) The Control Authority has performed the sampling and analysis in lieu of the
Industrial User, in which case the Control Authority shall perform the repeat sampling
and analysis unless it notifies the Industrial User of the violation and requires the
Industrial User to perform repeat analysis.
All Industrial Users shall promptly notify the POTW in advance of any substantial change in
volume or character of pollutants in their discharge, including the listed or characteristic
hazardous wastes for which the Industrial User has submitted initial notification under Sec.
24-6.3(A).
The Authority shall have the right to establish on the Discharger's property such devices
as are necessary to conduct sampling, inspection, or flow monitoring operations. Industrial
Wastewater monitoring shall be conducted in accordance with the methods and procedures
contained in the publication entitled "City of Oshkosh Industrial Discharge Program Handbook."
The Control Authority is hereby authorized to maintain and modify that program handbook as
may be necessary to comply with State and Federal agencies and/or directives. A current
copy of that handbook shall be maintained for public reading and copying in accordance
with other applicable ordinances, in the office of the City Clerk.
Samples shall be collected, handled, and preserved in such a manner as to be most
representative of the waste or process stream. The sampling procedures shall follow U.S.
Environmental Protection Agency (EPA) approved techniques. Sampling methods, location,
times, durations, and frequencies are to be determined on an individual basis by the Control
Authority.
The Control Authority may inspect the monitoring facilities of any Industrial Wastewater
Discharger to determine compliance with the requirements of this Ordinance. The
Discharger shall allow the Control Authority or its representatives, upon presentation of
credentials of identification, to enter upon the premises of the Discharger for the purposes
of inspection, sampling, or records examination.
Should the Discharger at any time, for any reason, refuse to allow inspection of the records
relating to industrial discharges, then the Control Authority is hereby expressly authorized to
seek a Special Inspection Warrant under Section 66.0119 of the Wisconsin Statutes.
(a) Monitoring Facilities
Each Person discharging Industrial Wastewater shall provide and maintain at the
Discharger's own expense, a monitoring facility to allow inspection, sampling, and
flow measurement of each wastewater discharge to the Wastewater System. Each
monitoring facility shall be situated on the Discharger's premises, except where such a
location would be impractical or cause undue hardship on the Discharger, the Authority
City of Oshkosh Chapter 24 — Page 20 Municipal Code
City of Oshkosh
Municipal Code
Revised 7/3/18
may concur with the monitoring facility being constructed in the public street or
sidewalk area provided that the facility is located so that access will not be obstructed.
There shall be ample room in and near each facility to allow accurate sampling and
preparation of samples for analysis. Plans for the monitoring facility and sampling and
measuring equipment shall be approved by the Control Authority prior to
commencement of construction. The facilities, including all equipment and
appurtenances, shall be accessible at all times and shall be maintained at all times in
a safe and proper operating condition at the expense of the Discharger. All
monitoring facilities shall be constructed and maintained in accordance with all
applicable construction standards and specifications. Construction shall be completed
within 120 days of receipt of plan approval from the Control Authority.
(b) Choice of Monitoring Location
Where a treated regulated process waste stream is combined prior to treatment
with Wastewaters other than those generated by the regulated process, the Industrial
User may monitor either the segregated process waste stream or the combined waste
stream for the purpose of determining compliance with applicable pretreatment
standards. If the Industrial User chooses to monitor the segregated process waste
stream, it shall apply the applicable Categorical Pretreatment Standard. If the
Industrial User chooses to monitor the combined waste stream, it shall apply an
alternative discharge limit calculated using the combined waste stream formula as
provided under 40 C.F.R. sc. 403.6(e). The Industrial User may change monitoring
points only after receiving approval from the Control Authority. The Control Authority
shall ensure that any change in an Industrial User's monitoring point(s) will not allow the
Industrial Userto substitute dilution for adequate treatment to achieve compliance with
applicable standards.
(c) Analysis
All measurements, tests, and analyses of the characteristics of waters and waste to
which reference is made in the Ordinance shall be determined in accordance with
the analytical procedures described in Chapter NR 219 "Analytical Test Methods and
Procedures," Wisconsin Administrative Code, the provisions of 40 C.F.R. Part 136,
and the most recent edition of EPA's "Manual of Methods for Chemical Analysis of
Water and Wastes."
Determination of the character and concentration of the industrial wastes shall be the
responsibility of the Person discharging them, or their designated agent or
representative. All costs will be billed to the Industry in accordance with the methods
and procedures contained in this Ordinance. The Industrial User or Control Authority
may request split samples.
(G) Wastewater Discharge Permit
No significant industrial User discharging Industrial Wastewaters into the City's Wastewater
System shall discharge or cause to be discharged into the Wastewater System any
Wastewater except upon application to the Control Authority and upon receipt of a
Wastewater Discharge Permit. Application for a Wastewater Discharge Permit shall be on
a form furnished by the Authority. A Wastewater Discharge Permit shall be in addition to any
other permit required for connection to the Public Sewer system. The fee required for a

Similarly, each Significant Industrial Wastewater Discharger desiring to make a new
connection or to modify an existing process or connection to the Wastewater System shall
apply for a new Wastewater Discharge Permit, at least 90 days before desiring such
modification or connection and shall receive a permit before the process modification or
connection is made to the Wastewater System. The City shall may deny a Wastewater Discharge
Permit to any applicant whose waste is unacceptable as a discharge to the POTW per the
Ordinance.
(1) Individual Wastewater Discharge Permits must contain:
(a) A statement that indicates the Wastewater Discharge Permit issuance date,
expiration date and effective date;
(b) A statement that the Wastewater Discharge Permit is nontransferable without
prior notification to the Control Authority in accordance with Section 24-6.3 (4)
of this Ordinance, and provisions for furnishing the new owner or operator with
a copy of the existing Wastewater Discharge Permit;
(c) Effluent limits, including Best Management Practices, based on applicable
Pretreatment Standards;
(d) Self-monitoring, sampling, reporting, notification, and record-keeping
requirements. These requirements shall include an identification of pollutants
(or Best Management Practice) to be monitored, sampling location, sampling
frequency, and sample type based on Federal, State, and local law.
(e) A statement of applicable civil and criminal penalties for violation of Pretreatment
Standards and requirements, and any applicable compliance schedule. Such
schedule may not extend the time for compliance beyond that required by

(f) Requirements to control Slug Discharge, if determined by the Control Authority
to be necessary.
(2) Permit Modifications
The Control Authority is hereby authorized to amend any Wastewater Discharge
Permit issued hereunder in order to assure compliance by the Authority with
applicable laws and regulations. Within nine (9) months of the promulgation of a
Federal Categorical Pretreatment Standard, the Wastewater Discharge Permit of
each Discharger subject to such standard shall be revised to require compliance with
such standards within the time frame prescribed by such standards. All Federal
Categorical Pretreatment Standards promulgated after the adoption of this Ordinance
shall be included, by reference, as a part of this Ordinance effective on the date
of promulgation of the Pretreatment Standard. Where an existing Industrial User
City of Oshkosh Chapter 24 — Page 22 Municipal Code
City of Oshkosh Municipal Code
Revised 7/3/18
becomes subject to new Federal Categorical Pretreatment Standards after issuance
of its original Wastewater Discharge Permit, the industrial discharger shall, within 180
days of issuance of the new standard, apply for a new Wastewater Discharge Permit
from the Control Authority. The industry shall then be informed of any proposed
changes in the existing permit at least 30 days prior to the effective date of change. Any
changes or new conditions in the permit shall include a reasonable time schedule for
compliance.
(3) Permits Duration
All Wastewater Discharge Permits shall be issued for a period not to exceed five
(5) years, subject to amendment or revocation as provided in this Ordinance.

(a) All Wastewater Discharge Permit applications, User reports and certification
statements must be signed by an Authorized Representative of the Industrial
User and contain the certification statement specified in Section 24-6.3(L).
(b) If the designation of an Authorized Representative is no longer accurate because
a different individual or position has responsibility for the overall operation of the
facility or overall responsibility for environmental matter for the industry, a new
written authorization satisfying the requirements of this section must be
submitted to the Pretreatment Coordinator prior to, or together with any reports
to be signed by an Authorized Representative.
(H) Sampling and Analysis Techniques
Sampling and analysis shall be performed in accordance with the techniques prescribed in 40
C.F.R. Part 136 and amendments thereto. Where 40 C.F.R. Part 136 does not contain
sampling or analytical techniques for the pollutant in question, or where the Control Authority
determines that the Part 136 sampling and analytical techniques are inappropriate for the
pollutant in question, sampling and analysis shall be performed by using validated analytical
methods or any other applicable sampling and analytical procedures, including procedures
suggested by the Control Authority.
(1) Use of Historical Data
The Control Authority may allowthe submission of a baseline reportwhich utilizes only historical
data so long as the data provides information sufficient to determine the need for industrial
pretreatment measures.
City of Oshkosh Chapter 24 — Page 23 Municipal Code
City of Oshkosh
(J) Specifics of Sampling and Methods of Analysis
Municipal Code
Revised 7/3/18
The baseline report shall indicate the time, date and place, of sampling, and methods of
analysis, and shall certify that such sampling and analysis is representative of normal work
cycles and expected pollutant discharges to the POTW.
(K) Reporting Requirements for Industrial Users Not Subject to Categorical Pretreatment
Standards
The Control Authority shall require appropriate reporting from those Industrial Users with
discharges that are not subject to Categorical Pretreatment standards. Significant Non -
Categorical Industrial Users shall submit to the Control Authority at least once every six
months (on dates specified by the Control Authority) a description of the nature, concentration,
and flow of the pollutants required to be reported by the Control Authority. These reports shall
be based on sampling and analysis performed in the period covered by the report, and
performed in accordance with the techniques described in 40 CFR part 136 and amendments
thereto. Where 40 CFR part 136 does not contain sampling or analytical techniques for
the pollutant in question, or where the Administrator determines that the part 136 sampling
and analytical techniques are inappropriate for the pollutant in question, sampling and analysis
shall be performed by using validated analytical methods or any other applicable sampling
and analytical procedures, including procedures suggested by the POTW or other persons,
approved by the Administrator. Sampling shall be conducted at the appropriate sampling
location and shall be representative of conditions during the reporting period. If a User
monitors any regulated pollutant more frequently than required by the Control Authority using
procedures prescribed in Section 24-6.3(F), the results of this monitoring shall be included in
the report. In cases where a local limit requires compliance with best management practices
or pollution prevention alternative, the User shall submit documentation required by the Control
Authority to determine the compliance status of the User. This sampling and analysis may
be performed by the Control Authority in lieu of the Significant Non -Categorical Industrial
User. Where the Control Authority itself collects all the information required for the report,
the Significant Non -Categorical Industrial User will not be required to submit the report.
The decision to sample any Industrial User not deemed a Significant Industrial User by the
Control Authority shall rest with the Control Authority, and the requirements set forth in this
chapter regulating Significant Industrial Users shall not prohibit the Control Authority from
making arrangements with individual industries with regard to sampling and reporting
requirements.

SECTION 24-6.7 VIOLATIONS AND PENALTIES
(A)
Administrative Enforcement Remedies
(1) Notification of Violation
City of Oshkosh Chapter 24 — Page 31 Municipal Code
City of Oshkosh
Municipal Code
Revised 7/3/18
When the Control Authority finds that a User has violated, or continues to violate, any
provision of this Ordinance, a Wastewater Discharge Permit or Order issued hereunder, or
any other pretreatment standard or requirement, the Control Authority may serve upon that
User a written Notice of Violation. Within thirty (30) days of receipt of this notice, an
explanation of the violation and a plan for the satisfactory correction and prevention
thereof, to include specific required actions, shall be submitted by the User to the Control
Authority. Submission of this plan in no way relieves the User of liability for any violations
occurring before or after receipt of the Notice of Violation. If sampling performed by a
User indicates a violation, the User must notify the Pretreatment Coordinator
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 Pretreatment Coordinator 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. Nothing in this Section shall Iimitthe authority of the Control Authority to
take any action, including emergency actions or any other enforcement action, without first
issuing a Notice of Violation.
(2) Consent Orders
The Control Authority may enter into consent orders, assurances of voluntary compliance,
or other similar documents establishing an agreement with any User responsible for
noncompliance. Such documents will include specific action to be taken by the User to
correct the noncompliance within a time period specified by the document. Such documents
shall have the same force and effect as the administrative orders issued pursuant to Sections
24-6.7(A)(4) and (5) of this ordinance and shall bejudicially enforceable.
(3) Show Cause Hearing
The Control Authority may order a User which has violated, or continues to violate,
any provisions of this ordinance, a wastewater discharge permit or order issued
hereunder, or any other pretreatment standard or requirement, to appear before the Control
Authority and show cause why the proposed enforcement action should not be taken.
Notice shall be served on the User specifying the time and place for the meeting, the
proposed enforcement action, the reasons for such action, and a request that the User
show cause why the proposed enforcement action should not be taken. The notice of the
meeting shall be served personally or by registered or certified mail (return receipt
requested) at least five (5) days prior to the hearing. Such notice may be served on any
Authorized Representative of the User. A show cause hearing shall not be a bar against,
or prerequisite for, taking any other action against the User.
(4) Compliance Orders
When the Control Authority finds that a User has violated, or continues to violate, any
provision of this ordinance, a wastewater discharge permit or order issued hereunder, or
any other pretreatment standard or requirement, the Control Authority may issue an order
to the User responsible for the discharge directing that the User come into compliance
within a specified time. If the User does not come into compliance within the time
provided, sewer service may be discontinued unless adequate treatment facilities, devices,
or other related appurtenances are installed and properly operated. Compliance orders
City of Oshkosh Chapter 24 — Page 32 Municipal Code
City of Oshkosh
(5)
Municipal Code
Revised 7/3/18
also may contain other requirements to address the noncompliance, including additional
self-monitoring and management practices designed to minimize the amount of pollutants
discharged to the sewer. A compliance order may not extend the deadline for compliance
established for a pretreatment standard or requirement, nor does a compliance order
relieve the User of liability for any violation, including any continuing violation. Issuance
of a compliance order shall not be a bar against, or a prerequisite for taking any other
action against the User.
Cease and Desist Orders
When the Control Authority finds that a User has violated, or continues to violate, any
provision of this ordinance, a wastewater discharge permit or order issued hereunder, or
any other pretreatment standard or requirement, or that the User's past violations are
likely to reoccur, the Control Authority may issue an order to the User directing it to cease
and desist all such violations and directing the User to:
(a) Immediately comply with all requirements; and
(b) Take such appropriate remedial or preventative action as may be needed to properly
address a continuing or threatened violation, including halting operations and/or
terminating the discharge.
Issuance of a cease and desist order shall not be a bar against, or a prerequisite for,
taking any other action against the User.
(6) Emergency Suspensions
The Control Authority may immediately suspend a User's discharge, with limited and /or
no prior notice, whenever such suspension is necessary to stop an actual or threatened
discharge which reasonably appears to present or cause an imminent or substantial
endangerment to the health or welfare of persons. The Control Authority may also
immediately suspend a User's discharge, after notice and opportunity to respond, that
threatens to interfere with the operation of the POTW, or which presents, or may present,
an endangerment to individuals or the environment.
(a) Any User notified of a suspension of its discharge shall immediately stop or eliminate
its discharge. In the event of a User's failure to immediately comply voluntarily with
the suspension order, the Control Authority may take steps as deemed necessary,
including immediate severance of the sewer connection, to prevent or minimize
damage to the POTW, its receiving stream, or endangerment to any individuals or
the environment. The Control Authority may allow the User to recommence its
discharge when the User has demonstrated to the satisfaction of the Control
Authority that the danger has passed, unless the termination proceedings in
Section 24- 6.7(A)(7) of this Ordinance are initiated against the User.
(b) A User that is responsible, in whole or in part, for any discharge presenting imminent
endangerment shall submit a detailed written statement, describing the causes of
the harmful contribution and the measures taken to prevent any future occurrence,
to the Control Authority prior to the date of any show cause or termination hearing
under Sections 24-6.7(3) or (7) of this ordinance.
Nothing in this Section shall be interpreted as requiring a hearing prior to any
emergency suspension under this Section. If the cause of the emergency suspension
City of Oshkosh Chapter 24 — Page 33 Municipal Code
City of Oshkosh Municipal Code
Revised 7/3/18
cannot be rectified the Control Authority may move to terminate the discharge under
conditions of Section 24-6.7(A)(7).
(7) Termination of Discharge
In addition to any other provisions in this Ordinance, any User who violates the following
conditions is subject to discharge termination:
(a) violation of Wastewater Discharge Permit conditions;
(b) failure to accurately report the Wastewater Constituents and Characteristics of
its discharge;
(c) failure to report significant changes in operations, volume, or Wastewater
Constituents and Characteristics prior to discharge;
(d) refusal of reasonable access to the Users premises for the purposes of
inspection, monitoring, or sampling; or
(e) violation of the pretreatment standards in this Ordinance.
Such Userwill be notified of the proposed termination of its discharge and be offered an opportunity
to show cause under Section 24-6.7(A)(3) of this Ordinance why the proposed action should not
be taken. Exercise of this option by the Control Authority shall not be a bar to, or a prerequisite
for, taking any other action against the User.
(B) Judicial Enforcement Remedies
(1) Injunctive Relief
When the Control Authority finds that User has violated, or continues to violate, any provision
of this Ordinance, a Wastewater Discharge Permit, or Order issued hereunder, or any
other pretreatment standard or requirement, the Control Authority may petition the circuit
court for the issuance of a temporary or permanent injunction, as appropriate, which
restrains or compels the specific performance of the Wastewater Discharge Permit, Order,
or other requirement imposed by this Ordinance on activities of the User. The Control
Authority may also seek such other action as is appropriate for legal and/or equitable
relief, including a requirement for the User to conduct environmental remediation. A
petition for injunctive relief shall not be a bar against, or a prerequisite for, taking any other
action against a User.
(C) Civil Penalties
(1) A User who has violated, or continues to violate, any provision of this Ordinance,
Wastewater Discharge Permit, or Order issued hereunder, or any other pretreatment
standard or requirement shall be liable to the city for a civil penalty of not less than $1025
nor more than $5000 per violation, per day. In the case of a monthly or other long-term
average discharge limit, penalties shall accrue for each day during the period of the
violation.
(2) The Control Authority may recover reasonable attorney fees, court costs, and other
City of Oshkosh Chapter 24 — Page 34 Municipal Code
City of Oshkosh Municipal Code
Revised 7/3/18
expenses associated with enforcement activities, including sampling and monitoring
expenses, and the cost of any actual damages incurred by the City.
(3) In determining the amount of civil liability, the court shall take into account all relevant
circumstances, including, but not limited to, the extent of harm caused by the violation,
the magnitude and duration of the violation, corrective actions by the User, the
compliance history of the User, and any other factor.
(4) Issuance of a citation, or filing a suit for civil penalties shall not be a bar against, or a
prerequisite for, taking any other action against a User.
(D) Remedies Nonexclusive
The remedies provided for in this Ordinance are not exclusive. The Control Authority may take
any, all, or any combination of these actions against a noncompliant User. Enforcement of
pretreatment violations will generally be in accordance with the City's Enforcement Response Plan.
However, the Control Authority may take other action against any User when the circumstances
warrant. Further, the Control Authority is empowered to take more than one enforcement action
against any noncompliant User.
(E) Supplemental Enforcement Action
Termination of Water Service
The Control Authority may decline to issue or reissue a Wastewater Discharge Permit to any
User who has failed to comply with any provision of this ordinance, Wastewater Discharge
Permit, or Order issued hereunder, or any other pretreatment standard or requirement. Water
service to the User may be severed. Service will only recommence, at the User's expense, after
it has satisfactorily demonstrated its ability to comply.
(F) Accidental Discharge
Any person found to be responsible for allowing a deleterious discharge into the Sewer System
which causes damage to the treatment facility and/or receiving body of water shall, in addition
to a fine, pay the amount to cover the damages, both values to be established by the Control
Authority.
(G) Continued Violation

numeric pretreatment standard or requirement including an instantaneous limit.
(2) Technical Review Criteria (TRC) violations, defined here as those in which thirty-
three percent (33%) or more of all of the measurements of the Industrial User's
Wastewater for the same pollutant parameter taken during a six month period equaled
or exceeded the product of the numeric pretreatment standard or requirement
including an instantaneous limit multiplied by the applicable TRC (TRC=1.4 for BOD,
TSS, fats, oil, and grease, and 1.2 for all other pollutants except pH, or exceeded a pH
limit by 0.4 standard units).
(3) Any other violation of a pretreatment standard or requirement that the Control
Authority determines has caused, alone or in combination with other discharges,
Interference or Pass Through (including endangering the health of POTW personnel

hazardous waste under 40 CFR part 261. Such notification must include the name of the
hazardous waste under 40 CFR part 261, the EPA hazardous waste number, and the type of
discharge (continuous, batch, or other.) If the Industrial User discharges more than 100
kilograms of such waste per calendar month to the POTW, the notification shall also contain
the following information to the extent such information is known and readily available to the
Industrial User:
(1) an identification of the hazardous constituents contained in the wastes; and
(2) an estimation of the mass and concentration of such constituents in the waste stream
discharge during that calendar month; and

(M) Bypass
Municipal Code
Revised 7/3/18
Bypass is the intentional diversion of waste streams from any portion of an Industrial User's
pretreatment facility. Bypass is prohibited under this Chapter unless:
(1) The bypass was unavoidable to prevent the loss of life, personal injury, or 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 (but severe property damage
does not mean economic loss caused by delays in production); and
(2) There were no reasonable alternatives to the bypass, such as the use of auxiliary treatment
facilities, retention of untreated wastes, or proper maintenance during periods of equipment
downtime to prevent failure; and
(3) The Industrial User submitted a notice of an anticipated bypass and received a written
approval from the Control Authority, or the Industrial User submitted an oral notice of
an unanticipated bypass within 24 hours, and a written submission within 5 days of the time
the Industrial User becomes aware of the bypass. Such written submission shall include:
(a) a description of the bypass and its cause; and
(b) 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
(c) the steps taken or planned to reduce, eliminate, and prevent reoccurrence of
the bypass.
The Control Authority may approve an anticipated bypass, after considering its adverse effects,
if the Control Authority determines that itwill meet the three conditions listed above under (1) (2)
and (3).
