          1.  To prevent the introduction of pollutants into the Publicly Owned Treatment Works that will interfere with its operation;
          2.  To prevent the introduction of pollutants into the Publicly Owned Treatment Works that will pass through the Publicly Owned Treatment Works, inadequately treated, into receiving waters, or otherwise be incompatible with the Publicly Owned Treatment Works;
          3.  To protect both Publicly Owned Treatment Works personnel who may be affected by wastewater and sludge in the course of their employment and the general public;
          4.  To promote reuse and recycling of industrial wastewater and sludge from the Publicly Owned Treatment Works;
          5.  To provide for fees for the equitable distribution of the cost of operation, maintenance, and improvement of the City of Westminster pretreatment program; and
          6.  To enable the City to comply with its National Pollutant Discharge Elimination System permit conditions, sludge use and disposal requirements, and any other Federal or State laws to which the Publicly Owned Treatment Works is subject.

This Chapter shall apply to all users of the Publicly Owned Treatment Works.  This Chapter authorizes the issuance of wastewater discharge permits; provides for monitoring, compliance, and enforcement activities; establishes administrative review procedures; requires user reporting; and provides for the setting of fees for the equitable distribution of costs resulting from the program established herein.

(2)  Contributes a process wastestream which makes up five (5) percent or more of the average dry weather hydraulic or organic capacity of the POTW treatment plant; or
(3)  Is designated as such by the City on the basis that it has a reasonable potential for adversely affecting the POTW's operation or for violating any pretreatment standard or requirement.

(c)  The City may determine that an Industrial User subject to categorical pretreatment standards is a Non-Significant Categorical Industrial User rather than a Significant Industrial User on a finding that the Industrial User never discharges more than 100 gallons per day (gpd) of total categorical wastewater (excluding sanitary, non-contact cooling and boiler blowdown wastewater, unless specifically included in the Pretreatment Standard) and the following conditions are met:

(1)  the Industrial User, prior to City's finding, has consistently complied with all applicable categorical Pretreatment Standards and Requirements;

8-10-2:  GENERAL SEWER USE REQUIREMENTS – PRETREATMENT STANDARDS:  (3381)

(A)  Prohibited Discharge Standards:
          1.  General Prohibitions.  No user shall introduce or cause to be introduced into the POTW any pollutant or wastewater which causes pass through or interference.  These general prohibitions apply to all users of the POTW whether or not they are subject to categorical pretreatment standards or any other National, State, or local pretreatment standards or requirements. 
          2.  Specific Prohibitions.  No user shall introduce or cause to be introduced into the POTW the following pollutants, substances, or wastewater:

(a)  Pollutants which create a fire or explosive hazard in the POTW, including, but not limited to, wastestreams with a closed-cup flashpoint of less than 140 degrees F  (60 degrees C) using the test methods specified in 40 CFR 261.21;
(b)  Wastewater having a pH less than 5.5 or more than 10, or otherwise causing corrosive structural damage to the POTW or equipment.  Limitations on pH are instantaneous discharge limitations;
(c)  Solid or viscous substances in amounts which will cause obstruction of the flow in the POTW resulting in interference;
(d)  Pollutants, including oxygen-demanding pollutants (BOD, etc.), released in a discharge at a flow rate and/or pollutant concentration which, either singly or by interaction with other pollutants, will cause interference with the POTW;
(e)  Wastewater having a temperature which will inhibit biological activity in the treatment plant resulting in interference, but in no case wastewater which causes the temperature at the introduction into the treatment plant to exceed 104 degrees F (40 degrees C);
(f)  Petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin, in amounts that will cause interference or pass through;
(g)  Pollutants which result in the presence of toxic gases, vapors, or fumes within the POTW in a quantity that may cause acute worker health and safety problems;
(h)  Noxious or malodorous liquids, gases, solids, or other wastewater which, either singly or by interaction with other wastes, are sufficient to create a public nuisance or a hazard to life, or to prevent entry into the sewers for maintenance or repair;
(i)  Wastewater which imparts color which cannot be removed by the treatment process, such as, but not limited to, dye wastes and vegetable tanning solutions, which consequently imparts color to the treatment plant's effluent, thereby violating the City's NPDES permit;
(j)  Wastewater causing, alone or in conjunction with other sources, the treatment plant's effluent to fail toxicity testing;
(k)  Wastewater containing any radioactive wastes or isotopes except in compliance with applicable State or Federal regulations;
(l)  Storm water, surface water, ground water, artesian well water, roof runoff, and subsurface drainage, unless specifically authorized by the City Manager;
(m)  Sludges, screenings, or other residues from the pretreatment of industrial wastes;
(n)  Fats, oils, or greases of animal or vegetable origin in amounts that will cause interference or pass through;
(o)  Trucked or hauled pollutants, except at discharge points designated by the City Manager and in accordance with Section 8-10-3(D) of this Chapter.

(B)  National Categorical Pretreatment Standards:

The categorical pretreatment standards found at 40 CFR Chapter I, Subchapter N, Parts 405-471 are hereby incorporated.  Users must comply with applicable categorical standards.

          1.  Where a categorical pretreatment standard is expressed only in terms of either the mass or the concentration of a pollutant in wastewater, the City Manager may impose equivalent concentration or mass limits in accordance with Section 8-10-2(B)(4) and (B)(5).
          2.  When the limits in a categorical Pretreatment Standard are expressed only in terms of mass of pollutant per unit of production, the City Manager may convert the limits to equivalent limitations expressed either as mass of pollutant discharged per day or effluent concentration for purposes of calculating effluent limitations applicable to individual Industrial Users. 
          3.  When wastewater subject to a categorical pretreatment standard is mixed with wastewater not regulated by the same standard, the City Manager shall impose an alternate limit in accordance with 40 CFR 403.6(e).
          4.  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 City Manager.  The City may establish equivalent mass limits only if the Industrial User meets all of the conditions set forth in Sections 8-10-2(B)(4)(a)(1) through 8-10-2(B)(4)(a)(5) below.

(a)  To be eligible for equivalent mass limits, the Industrial User must:

(1)  Employ, or demonstrate that it will employ, water conservation methods and technologies that substantially reduce water use during the term of its control mechanism;
(2)  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;
(3)  Provide sufficient information to establish the facility’s actual average daily flow rate for all wastestreams, 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;
(4)  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
(5)  Have consistently complied with all applicable categorical Pretreatment Standards during the period prior to the Industrial User’s request for equivalent mass limits.

(b)  An Industrial User subject to equivalent mass limits must:

(1)  Maintain and effectively operate control and treatment technologies adequate to achieve compliance with the equivalent mass limits;
(2)  Continue to record the facility’s flow rates through the use of a continuous effluent flow monitoring device;
(3)  Continue to record the facility’s production rates and notify the City Manager whenever production rates are expected to vary by more than 20 percent from its baseline production rates determined in section 8-10-2(B)(4)(a)(3) of this Section.  Upon notification of a revised production rate, the City Manager must reassess the equivalent mass limit and revise the limit as necessary to reflect changed conditions at the facility; and
(4)  Continue to employ the same or comparable water conservation methods and technologies as those implemented pursuant to paragraphs 2.2D(1)(a) of this Section so long as it discharges under an equivalent mass limit.

(c)  When developing equivalent mass limits, the City Manager:

(1)  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;
(2)  Upon notification of a revised production rate, will reassess the equivalent mass limit and recalculate the limit as necessary to reflect changed conditions at the facility; and
(3)  May retain the same equivalent mass limit in subsequent control mechanism 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 8-10-2(F).  The Industrial User must also be in compliance with Section 8-10-13(C) regarding the prohibition of bypass. 

          5.  The City Manager may convert the mass limits of the categorical pretreatment standards of 40 CFR Parts 414 and 455 to concentration limits for purposes of calculating limitations applicable to individual Industrial Users.  The conversion is at the discretion of the City Manager.  When converting such limits to concentration limits, the City Manager must use the concentrations listed in the applicable subparts of 40 CFR Parts 414, 419, and 455 and document that dilution is not being substituted for treatment as prohibited by Section 8-10-2(F) of this ordinance. 
          6.  The City Manager must document how the equivalent limits were derived for any changes from concentration to mass limits or vice versa and make this information publicly available. 
          7.  Once incorporated into its control mechanism, the Industrial User must comply with the equivalent limitations developed in this Section 8-10-2(B) in lieu of the promulgated categorical standards from which the equivalent limitations were derived.
          8.  Where categorical Pretreatment Standards specify one limit for calculating maximum daily discharge limitations and a second limit for calculating maximum monthly average, or 4-day average, limitations, the same production or flow figure shall be used in calculating both the average and the maximum equivalent limitation. 
          9.  Any Industrial User operating under a control mechanism incorporating equivalent mass or concentration limits calculated from a production based standard shall notify the City Manager within two (2) business days after the User has a reasonable basis to know that the production level will significantly change within the next calendar month.  Any User not notifying the City Manager of such anticipated change will be required to meet the mass or concentration limits in its control mechanism that were based on the original estimate of the long term average production rate.

(C)  State Pretreatment Standards:  (reserved)

(D)  Local Limits:
          1.  The City Manager is authorized to establish local limits pursuant to 40 CFR 403.5(c). 
          2.  The following pollutant limits are established to protect against pass through and interference. 
          3.  Daily Maximum Discharge Limits: No person shall discharge wastewater containing in excess of the following maximum limits.  These limits apply at the point where the wastewater is discharged to the POTW.  The City Manager may impose mass-based limitations in addition to the concentration-based limits below.

 0.13 mg/l arsenic (total)
0.10 mg/l cadmium (total)
4.63 mg/l chromium (total)
1.26 mg/l chromium (VI)
2.69 mg/l copper (total)
0.77 mg/l lead (total)
0.0005 mg/l mercury (total)
0.84 mg/l molybdenum (total)
1.82 mg/l nickel (total)
0.13 mg/l selenium (total)
0.91 mg/l silver (total)
8.44 mg/l zinc (total) 

          4.  Pollutant Loadings: The following are the total cumulative pollutant loadings allowed from all commercial dischargers.  The City manager may limit the discharge of pollutants from commercial dischargers as necessary to meet the following daily allowable loadings.

0.07 lbs/day arsenic (total)
0.05 lbs/day cadmium (total)
2.52 lbs/day chromium (total)
0.69 lbs/day chromium (VI)
1.47 lbs/day copper (total)
0.42 lbs/day lead (total)
0.053 lbs/day mercury (total)
0.46 lbs/day molybdenum (total)
0.99 lbs/day nickel (total)
0.07 lbs/day selenium (total)
0.49 lbs/day silver (total)
4.60 lbs/day zinc (total) 

         5.  The City Manager may develop Best Management Practices (BMPs), by ordinance or in wastewater discharge permits, to implement local limits and the requirements of Section 8-10-2(A) and 8-10-2(D).

(E)  City's Right of Revision:  The City reserves the right to establish, by ordinance or in wastewater discharge permits, more stringent standards or requirements on discharges to the POTW consistent with the purposes 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 City Manager 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.

8-10-3:  PRETREATMENT OF WASTEWATER:  (3381)

(A)  Pretreatment Facilities:  Users shall provide wastewater treatment as necessary to comply with this ordinance and shall achieve compliance with all categorical pretreatment standards, local limits, and the prohibitions set out in Section 8-10-2(A) of this ordinance within the time limitations specified by EPA, the State, or the City Manager, whichever is more stringent.  Any facilities necessary for compliance shall be provided, operated, and maintained at the user's expense.  Detailed plans describing such facilities and operating procedures shall be submitted to the City Manager for review, and shall be acceptable to the City Manager before such facilities are constructed.  The review of such plans and operating procedures shall in no way relieve the user from the responsibility of modifying such facilities as necessary to produce a discharge acceptable to the City of Westminster under the provisions of this ordinance.

(B)  Additional Pretreatment Measures:
          1.  Whenever deemed necessary, the City Manager may require users to restrict their discharge during peak flow periods, designate that certain wastewater be discharged only into specific sewers, relocate and/or consolidate points of discharge, separate domestic sewage wastestreams from industrial wastestreams, and such other conditions as may be necessary to protect the POTW and determine the user's compliance with the requirements of this ordinance.
          2.  The City Manager may require any person discharging into the POTW to install and maintain, on their property and at their expense, a suitable storage and flow-control facility to ensure equalization of flow.  A wastewater discharge permit may be issued solely for flow equalization.
          3.  Grease, oil, and sand interceptors shall be provided when, in the opinion of the City Manager, they are necessary for the proper handling of wastewater containing excessive amounts of grease and oil, or solids; except that such interceptors shall not be required for residential users.  All interceptors shall be of type and capacity approved by the City Manager, and shall be so located to be easily accessible for cleaning and inspection.  Such interceptors shall be inspected, cleaned, and repaired by the user at their expense.  Cleaning and maintenance requirements may be specified by the City Manager.
          4.  Users with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas detection meter.

(C)  Accidental Discharge/Slug Discharge Control Plans:  The City Manager shall evaluate whether each SIU needs an accidental discharge/slug discharge control plan or other action to control slug discharges.  The City Manager may require any user to develop, submit for approval, and implement such a plan or take such other action that may be necessary to control slug discharges.  An accidental discharge/slug discharge control plan shall address, at a minimum, the following:
          1.  Description of discharge practices, including nonroutine batch discharges;
          2.  Description of stored chemicals;
          3.  Procedures for immediately notifying the City Manager of any accidental or slug discharge, as required by Section 8-10-6(F) of this ordinance; and

(2)  The user shall take a minimum of one sample representative of daily operations to compile that data necessary to comply with the requirements of this Section.
(3)  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 wastestream formula of 40 CFR 403.6(e) in order to evaluate compliance with the Pretreatment Standards. Where an alternate concentration or mass limit has been calculated in accordance with 40 CFR 403.6(e) this adjusted limit along with supporting data shall be submitted to the City;
(4)  Sampling and analysis shall be performed in accordance with section 8-10-6(J).
(5)  The City Manager may allow the submission of a baseline report which utilizes only historical data so long as the data provides information sufficient to determine the need for industrial pretreatment measures;
(6)  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.

(c)  Compliance Certification.  A statement, reviewed by the user's authorized representative as defined in Section 8-10-1(D)(2) and certified by a qualified professional, indicating whether pretreatment standards are being met on a consistent basis, and, if not, whether additional operation and maintenance (O&M) and/or additional pretreatment is required to meet the pretreatment standards and requirements.
(d)  Compliance Schedule.  If additional pretreatment and/or O&M will be required to meet the pretreatment standards, the shortest schedule by which the user will provide such additional pretreatment and/or O&M must be provided.  The completion date in this schedule shall not be later than the compliance date established for the applicable pretreatment standard.  A compliance schedule pursuant to this Section must meet the requirements set out in Section 8-10-6(B) of this ordinance.

          1.  The schedule shall contain progress increments in the form of dates for the commencement and completion of major events leading to the construction and operation of additional pretreatment required for the user to meet the applicable pretreatment standards (such events include, but are not limited to, hiring an engineer, completing preliminary and final plans, executing contracts for major components, commencing and completing construction, and beginning and conducting routine operation);
          2.  No increment referred to above shall exceed nine (9) months;
          3.  The user shall submit a progress report to the City Manager no later than fourteen (14) days following each date in the schedule and the final date of compliance including, as a minimum, whether or not it complied with the increment of progress, the reason for any delay, and, if appropriate, the steps being taken by the user to return to the established schedule; and
          4.  In no event shall more than nine (9) months elapse between such progress reports to the City Manager.

(C)  Reports on Compliance with Categorical Pretreatment Standard Deadline:  Within ninety (90) days following the date for final compliance with applicable categorical pretreatment standards, or in the case of a new source following commencement of the introduction of wastewater into the POTW, any user subject to such pretreatment standards and requirements shall submit to the City Manager a report containing the information described in Section 8-10-4(F)(1)(f) and (g) and 8-10-6(A)(2)(b) of this ordinance.  For users subject to equivalent mass or concentration limits established in accordance with the procedures in Section 8-10-2(B), this report shall contain a reasonable measure of the user's long-term production rate.  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 8-10-6(N)(1) of this ordinance. All sampling will be done in conformance with Section 8-10-6(K).

(D)  Periodic Compliance Reports:
          1.  All significant industrial users must submit reports no less than twice per year (in June and December or on other dates specified by the City Manager), indicating the nature, concentration, and flow 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 City Manager or the Pretreatment Standard necessary to determine the compliance status of the User.  The City Manager may require reporting more frequently than twice per year.
          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.  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 Permit, but in no case longer than 5 years.  The User must submit a new request for the waiver before the waiver can be granted for each subsequent control mechanism.
(c)  In making a demonstration that a pollutant is not present, the Industrial User must provide data from at least one 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 Section 8-10-1(D)(2), and include the certification statement in 8-10-6(N)(1).
(e)  Non-detectable sample results may only be used as a demonstration that a pollutant is not present if the EPA approved method from 40 CFR Part 136 with the lowest minimum detection level for that pollutant was used in the analysis.
(f)  Any grant of the monitoring waiver by the City Manager 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 City Manager for 3 years after expiration of the waiver.
(g)  Upon approval of the monitoring waiver and revision of the User’s permit by the City Manager, the Industrial User must certify on each report with the statement in Section 8-10-6(N)(3), that there has been no increase in the pollutant in its wastestream 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 based on changes that occur in the User’s operations, the User must immediately: Notify the City manager and comply with the monitoring requirements of Section 8-10-6(D)(1), or other more frequent monitoring requirements imposed by the City Manager.
(i)  This provision does not supercede 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 8-10-6(N)(1) of this ordinance.
          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 City Manager, using the procedures prescribed in Section 8-10-6(K) of this ordinance, the results of this monitoring shall be included in the report.

(E)  Reports of Changed Conditions:  Each user must notify the City Manager of any significant changes to the user's operations or system which might alter the nature, quality, or volume of its wastewater at least thirty (30) days before the change.  A significant change for the purposes of this paragraph is an increase in the volume of wastewater of 20% or more, an increase in pollutant concentration or pollutant mass of 20% or more, or the addition any new regulated pollutant.
          1.  The City Manager 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 8-10-4(F) of this Chapter.
          2.  The City Manager may issue a wastewater discharge permit or modify an existing wastewater discharge permit 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 nonroutine, episodic nature, a noncustomary batch discharge, a slug discharge or slug load, that may cause potential problems for the POTW, the user shall immediately telephone and notify the POTW 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 City Manager, 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 may 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 ordinance.  
          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 paragraph 1, above.  Employers shall ensure that all employees, who may cause such a discharge to occur, are advised of the emergency notification procedure.
          4.  Significant Industrial Users are required to notify the City Manager immediately of any changes at its facility affecting potential for a slug discharge. 

(G)  Reports from Unpermitted Users:  All users not required to obtain a wastewater discharge permit shall provide appropriate reports to the City Manager as the City Manager may require.

(H)  Notice of Violation/Repeat Sampling and Reporting:  If sampling performed by a user indicates a violation, the user must notify the POTW 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 City Manager 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.

(I)  Notification of the Discharge of Hazardous Waste:
          1.  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 and 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 8-10-6(E) of this ordinance.  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 Sections 8-10-6(A), 8-10-6(C), and 8-10-6(D) of this ordinance.
          2.  Dischargers are exempt from the requirements of paragraph 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 261.30(d) and 261.33(e).  Discharge of more than fifteen (15) kilograms of nonacute hazardous wastes in a calendar month, or of any quantity of acute hazardous wastes as specified in 40 CFR 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.
          3.  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 POTW, 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.
          4.  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.
          5.  This provision does not create a right to discharge any substance not otherwise permitted to be discharged by this ordinance, a permit issued thereunder, or any applicable Federal or State law.

(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 Part 136 and amendments thereto, unless otherwise specified in an applicable categorical pretreatment standard.  If 40 CFR Part 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 City Manager 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.  The City Manager shall require that frequency of monitoring necessary to assess and assure compliance by the user with applicable pretreatment standards and requirements.

          1.  Except as indicated in Section 2 and 3 below, the 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 City Manager.  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 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 & 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. 
          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 8-10-6(A) and 8-10-6(C), 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 City Manager may authorize a lower minimum. For the reports required by Section 8-10-6(D), the City shall require the number of grab samples necessary to assess and assure compliance by industrial users with applicable pretreatment standards and requirements.

(L)  Date of Receipt of Reports:  Written reports delivered by mail or other carrier will be deemed to have been submitted on the date postmarked.  Other reports will be deemed submitted on the date of receipt.

8-10-7:  COMPLIANCE MONITORING:  (3381)

(A)  Right of Entry:  Inspection and Sampling:  The City Manager shall have the right to enter the premises of any user to determine whether the user is complying with all requirements of this ordinance and any wastewater discharge permit or order issued hereunder.  Users shall allow the City Manager ready access to all parts of the premises for the purposes of inspection, whether announced or unannounced, sampling, records examination and copying, and the performance of any additional duties.
          1.  Where a user has security measures in force which require proper identification and clearance before entry into its premises, the user shall make necessary arrangements with its security guards so that, upon presentation of suitable identification, the City Manager will be permitted to enter without delay for the purposes of performing specific responsibilities.
          2.  The City Manager shall have the right to set up on the user's property, or require installation of, such devices as are necessary to conduct sampling and/or metering of the user's operations.
          3.  The City Manager may require the user to install monitoring equipment as necessary.  The facility's sampling and monitoring equipment shall be maintained at all times in a safe and proper operating condition by the user at its own expense.  All devices used to measure wastewater flow and quality shall be calibrated to ensure their accuracy.  The City manager may specify the frequency of required calibrations.
          4.  Any temporary or permanent obstruction to safe and easy access to the facility to be inspected and/or sampled shall be promptly removed by the user at the written or verbal request of the City Manager and shall not be replaced.  The costs of clearing such access shall be born by the user.
          5.  Delays in allowing the City Manager access to the user's premises shall be a violation of this ordinance.

(B)  Search Warrants:  If the City Manager has been refused access to a building, structure, or property, or any part thereof, and is able to demonstrate probable cause to believe that there may be a violation of this ordinance, or that there is a need to inspect and/or sample as part of a routine inspection and sampling program of the City designed to verify compliance with this ordinance or any permit or order issued hereunder, or to protect the overall public health, safety and welfare of the community, then the City Manager may seek issuance of a search warrant from the Municipal Court.

8-10-8:  CONFIDENTIAL INFORMATION:  (3381)

Information and data on a user obtained from reports, surveys, wastewater discharge permit applications, wastewater discharge permits, and monitoring programs, and from the City Manager’s inspection and sampling activities, shall be available to the public without restriction, unless the user specifically requests, and is able to demonstrate to the satisfaction of the City Manager, that the release of such information would divulge information, processes, or methods of production entitled to protection as trade secrets under applicable State and federal law.  Any such request must be asserted at the time of submission of the information or data.  When requested and demonstrated by the user furnishing a report that such information should be held confidential, the portions of a report which might disclose trade secrets or secret processes shall not be made available for inspection by the public, but shall be made available immediately upon request to governmental agencies for uses related to the NPDES program or pretreatment program, and in enforcement proceedings involving the person furnishing the report.  Wastewater constituents and characteristics and other effluent data, as defined by 40 CFR 2.302 will not be recognized as confidential information and will be available to the public without restriction.

8-10-9:  PUBLICATION OF USERS IN SIGNIFICANT NONCOMPLIANCE:  (3381)

The City Manager shall publish at least annually, in a newspaper of general circulation that provides meaningful public notice within the jurisdictions served by the POTW, a list of the users which, at any time during the previous twelve (12) months, were in significant noncompliance with applicable pretreatment standards and requirements.  The term significant noncompliance shall be applicable to any significant industrial user that meets any of the criteria in paragraphs (A) through (H) below and any other user that meets the definition in paragraphs (C), (D) or (H) below.  Significant noncompliance shall mean:

(A)  Chronic violations of wastewater discharge limits, defined here as those in which sixty-six percent (66%) or more of all of the measurements taken for the same pollutant parameter taken during a six- (6-) month period exceed (by any magnitude) a numeric pretreatment standard or requirement, including instantaneous limits, as defined by 40 CFR 403.3(L);

(B)  Technical Review Criteria (TRC) violations, defined here as those in which thirty-three percent (33%) or more of wastewater measurements taken for each pollutant parameter during a six- (6-) month period equals or exceeds the product of the numeric pretreatment standard or requirement including instantaneous limits, as defined by 40 CFR 403.3(L), multiplied by the applicable criteria (1.4 for BOD, TSS, fats, oils and grease, and 1.2 for all other pollutants except pH);

(C)  Any other violation of a pretreatment standard or requirement, as defined by Section 8-10-1(D), (daily maximum, long-term average, instantaneous limit, or narrative standard) that the City Manager determines has caused, alone or in combination with other discharges, interference or pass through, including endangering the health of POTW personnel or the general public;

(D)  Any discharge of a pollutant that has caused imminent endangerment to the public or to the environment, or has resulted in the City Manager’s exercise of its emergency authority to halt or prevent such a discharge;

(E)  Failure to meet, within ninety (90) days of the scheduled date, a compliance schedule milestone contained in a wastewater discharge permit or enforcement order for starting construction, completing construction, or attaining final compliance;

(F)  Failure to provide within thirty (30) days after the due date, any required reports, including baseline monitoring reports, reports on compliance with categorical pretreatment standard deadlines, periodic self-monitoring reports, and reports on compliance with compliance schedules;

(G)  Failure to accurately report noncompliance; or

(H)  Any other violation(s), which may include a violation of Best Management Practices, which the City Manager determines will adversely affect the operation or implementation of the local pretreatment program.

8-10-10:  ADMINISTRATIVE ENFORCEMENT REMEDIES:  (3381)

(A)  Notification of Violation:  When the City Manager 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 City Manager may serve upon that user a written Notice of Violation.  The Notice of Violation may include specific required actions and may require the user to submit an explanation of the violation and a plan for the satisfactory correction and prevention thereof.  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.  Nothing in this Section shall limit the authority of the City Manager to take any action, including emergency actions or any other enforcement action, without first issuing a Notice of Violation.

(B)  Consent Orders:  The City Manager 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 8-10-10(D) and 8-10-10(E) of this ordinance and shall be judicially enforceable.

(C)  Show Cause Hearing:  The City Manager may order a user which 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, to appear before the City Manager 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 fourteen (14) days prior to the hearing.  Such notice may be served on any authorized representative of the user as defined in Section 8-10-1(D)(2).  A show cause hearing shall not be a bar against, or prerequisite for, taking any other action against the user.

(D)  Compliance Orders:  When The City Manager 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 City Manager 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 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.

(E)  Cease and Desist Orders:  When the City Manager 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 recur, the City Manager may issue an order to the user directing it to cease and desist all such violations and directing the user to:
          1.  Immediately comply with all requirements; and
          2.  Take such appropriate remedial or preventive 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.

(F)  Administrative Fines:
          1.  When the City Manager 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 City Manager may fine such user in an amount not to exceed $1000.00.  Such fines shall be assessed on a per-violation, per-day basis.  In the case of monthly or other long-term average discharge limits, fines shall be assessed for each day during the period of violation.
          2.  Unpaid charges, fines, and penalties shall be assessed and accrue interest in accordance with the provisions of Chapter 8 of Title 1, Westminster Municipal Code, entitled “Penalties and Interest,” as it may be amended from time to time.
          3.  Users desiring to dispute such fines must file a written request for the City Manager to reconsider the fine along with full payment of the fine amount within thirty (30) days of being notified of the fine.  Where a request has merit, the City Manager may convene a hearing on the matter.  In the event the user's appeal is successful, the payment, together with any interest accruing thereto, shall be returned to the user.  The City Manager may add the costs of preparing administrative enforcement actions, such as notices and orders, to the fine.
          4.  Issuance of an administrative fine shall not be a bar against, or a prerequisite for, taking any other action against the user.

(G)  Emergency Suspensions:  The City Manager may immediately suspend a user's discharge, after informal notice to the user, 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, or threatens to interfere with the operation of the POTW, or which presents, or may present, an endangerment to the environment.
          1.  Any user notified of a suspension of its discharge shall immediately stop or eliminate its contribution.  In the event of a user's failure to immediately comply voluntarily with the suspension order, the City Manager may take such 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.  The City Manager may allow the user to recommence its discharge when the user has demonstrated to the satisfaction of the City Manager that the period of endangerment has passed, unless the termination proceedings in Section 8-10-10(H) of this ordinance are initiated against the user.
          2.  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 City Manager prior to the date of any show cause or termination hearing under Sections 8-10-10(C) or 8-10-10(H) of this ordinance.

Nothing in this Section shall be interpreted as requiring a hearing prior to any Emergency
Suspension under this Section.

(H)  Termination of Discharge:  In addition to the provisions in Section 8-10-4(L) of this ordinance, any user who violates the following conditions is subject to discharge termination:
          1.  Violation of wastewater discharge permit conditions;
          2.  Failure to accurately report the wastewater constituents and characteristics of its discharge;
          3.  Failure to report significant changes in operations or wastewater volume, constituents, and characteristics prior to discharge;
          4.  Refusal of reasonable access to the user's premises for the purpose of inspection, monitoring, or sampling; or
          5.  Violation of the pretreatment standards in Section 8-10-2 of this ordinance.

Such user will be notified of the proposed termination of its discharge and be offered an opportunity to show cause under Section 8-10-10(C) of this ordinance why the proposed action should not be taken.  Exercise of this option by the City Manager shall not be a bar to, or a prerequisite for, taking any other action against the user.

8-10-11:  JUDICIAL ENFORCEMENT REMEDIES:  (3381)

(A)  Injunctive Relief:  When the City Manager 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 City Manager may petition the District Court through the City's Attorney 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 City Manager 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.

(B)  Civil Penalties:
          1.  A user who 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 shall be liable to the City for a maximum civil penalty of $1,000 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 City may recover reasonable attorneys' fees, court costs, and other 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, any economic benefit gained through the user's violation, corrective actions by the user, the compliance history of the user, and any other factor as justice requires.
          4.  Filing a suit for civil penalties shall not be a bar against, or a prerequisite for, taking  any other action against a user.

(C)  Criminal Prosecution:
          1.  A user who willfully or negligently violates any provision of this ordinance, a wastewater discharge permit, or order issued hereunder, or any other pretreatment standard or requirement shall, upon conviction, be guilty of a misdemeanor, punishable by a fine of not more than $1000.00 per violation, per day, or imprisonment for not more than one (1) year, or both.
          2.  A user who willfully or negligently introduces any substance into the POTW which causes personal injury or property damage shall be subject to the penalty provisions of State law.  This penalty shall be in addition to any other civil cause of action for personal injury or property damage available under State law.
          3.  A user who knowingly makes any false statements, representations, or certifications in any application, record, report, plan, or other documentation filed, or required to be maintained, pursuant to this ordinance, wastewater discharge permit, or order issued hereunder, or who falsifies, tampers with, or knowingly renders inaccurate any monitoring device or method required under this ordinance shall, upon conviction, be punished by a fine of not more than $1000.00 per violation, per day, or imprisonment for not more than one (1) year, or both.

(D)  Remedies Nonexclusive:  The remedies provided for in this ordinance are not exclusive.  The City Manager 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 City Manager may take other action against any user when the circumstances warrant.  Further, the City Manager is empowered to take more than one enforcement action against any noncompliant user.

8-10-12:  SUPPLEMENTAL ENFORCEMENT ACTION:  (3381)

(A)  Liability Insurance:  The City Manager may decline to issue or reissue a wastewater discharge permit to any user who has failed to comply with any provision of this ordinance, a previous 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.

(B)  Payment of Outstanding Fees and Penalties:  The City Manager may decline to issue or reissue a 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 ordinance, a previous wastewater discharge permit, or order issued hereunder.

(C)  Water Supply Severance:  Whenever 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, 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.

(D)  Public Nuisances:

A violation of any provision of this ordinance, a 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 City Manager.  Any person(s) creating a public nuisance shall be subject to the provisions of the Westminster Municipal Code governing such nuisances, including reimbursing the City for any costs incurred in removing, abating, or remedying said nuisance.

8-10-13:  AFFIRMATIVE DEFENSES TO DISCHARGE VIOLATIONS:  (3381)

(A)  Upset:
          1.  For the purposes of this Section, upset means an exceptional incident in which there is unintentional and temporary noncompliance with categorical pretreatment standards because of factors beyond the reasonable control of the user.  An upset does not include noncompliance 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 noncompliance with categorical pretreatment standards if the requirements of paragraph 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 workman-like manner and in compliance with applicable operation and maintenance procedures; and
(c)  The user has submitted the following information to the City Manager 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 containing the following information:

(1)  A description of the indirect discharge and cause of noncompliance;
(2)  The period of noncompliance, including exact dates and times or, if not corrected, the anticipated time the noncompliance is expected to continue; and
(3)  Steps being taken and/or planned to reduce, eliminate, and prevent recurrence of the noncompliance.

          4.  In any enforcement proceeding, the user seeking to establish the occurrence of an upset shall have the burden of proof.
          5.  Users will have the opportunity for a judicial determination on any claim of upset only in an enforcement action brought for noncompliance 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 noncompliance with the general prohibitions in Section 8-10-2(A)(1) of this ordinance or the specific prohibitions in Sections 8-10-2(A)(2)(c) through 8-10-2(A)(2)(j) of this ordinance 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 wastestreams 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 paragraphs 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 City Manager, at least ten (10) days before the date of the bypass, if possible. 
(b)  A user shall submit oral notice to the City Manager 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 City Manager 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:

(a)  Bypass is prohibited, and the City 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 paragraph 3 of this Section.

(b)  The City Manager may approve an anticipated bypass, after considering its adverse effects, if the City Manager determines that it will meet the three conditions listed in paragraph (C)(4)(a) of this Section.

8-10-14:  PRETREATMENT CHARGES AND FEES:  (3381)

(A)  The City may adopt reasonable fees for reimbursement of costs of setting up and operating the City's Pretreatment Program which may include:
          1.  Fees for wastewater discharge permit applications including the cost of processing such applications;
          2.  Fees for monitoring, inspection, and surveillance procedures including the cost of collection and analyzing a user's discharge, and reviewing monitoring reports submitted by users;
          3.  Fees for reviewing and responding to accidental discharge procedures and construction;
          4.  Fees for filing appeals;
          5.  Fees to recover administrative and legal costs associated with the enforcement activity taken by the City to address IU noncompliance; and 
          6.  Other fees as the City may deem necessary to carry out the requirements contained herein. 

(B)  These fees relate solely to the matters covered by this ordinance and are separate from all other fees, fines, and penalties chargeable by the City.
