(b)    Where recycling of water is used or other conditions prevail which cause the above-listed nonresidential users to produce more or less average daily sewage flow than that computed by the above formula when the EQU is multiplied by 280 gallons per day, the City Manager may establish the EQU using the formula set forth in subsection (c) of this section. Where the City Manager deems necessary, the PIF may be charged according to the above formula. Then, after the first 12 months of full operation have passed, where actual water use is observed, the PIF may be revised up or down based on actual water use.

(c)    PIFs shall be computed for nonresidential users that are not listed above by computing the hydraulic flow expected from the establishment. The EQU can be computed by dividing the expected daily flow by 280 gallons per day or by dividing the expected organic load in pounds of BOD5 per day by 0.47 pound of BOD5. The higher EQU obtained by the two methods shall be used in computing the PIF.

(d)    Sewer extension charges are as established by resolution of the City Council.

13.04.350 Industrial pretreatment program – Applicability, objectives, authority.

(a)    Applicability. This code sets forth uniform requirements for all industrial users discharging to the POTW and enables the City to comply with all applicable State and federal laws including the Clean Water Act and the General Pretreatment Regulations (40 CFR Part 403). Any industrial user, the discharge from which directly or indirectly enters the POTW from areas within or without the boundaries of the City of Grand Junction or Mesa County, shall be bound by this code as it now exists or may hereafter be amended. This code may be enforced against any industrial user.

(b)    Objectives. The objectives of this code are:

(1)    To prevent the introduction of pollutants into the publicly owned treatment works (POTW) that will interfere with the operation of the system or contaminate the resulting sludge;

(2)    To prevent the introduction of pollutants into the POTW which will pass through the system, inadequately treated, into receiving waters or the atmosphere or otherwise be incompatible with the system;

(3)    To improve the opportunity to recycle and reclaim wastewaters and sludges from the system;

(4)    To provide for and promote the general health, safety and welfare of the citizens residing within the City or County and connecting jurisdictions;

(5)    To enable the City to comply with its Colorado Discharge Permit System (CDPS) permit conditions, sewage sludge use and disposal requirements, and any other applicable federal or State laws or regulations to which the POTW is subject;

(6)    To prevent adverse impacts to worker health and safety due to the discharge of pollutants from industrial users; and

(7)    To provide for fees for the equitable distribution of the cost of operation, maintenance, and improvement of the POTW.

(c)    Nondomestic Industrial Users. It shall be unlawful for any industrial user to discharge any domestic or nondomestic wastewater into any natural waterway, any surface drainage, or storm drain in any area under the jurisdiction of the City. No industrial wastewater shall be discharged to the POTW unless done so in compliance with the provisions of this code.

(d)    Responsibility and Authority of the City.

(1)    Except as otherwise provided herein, the City Manager shall administer, implement, and enforce the provisions of this code. Any powers granted to or duties imposed upon the City Manager may be delegated by the City Manager to other City personnel.

Failure of the City to so notify industrial users shall not relieve said industrial users from the responsibility of complying with applicable pretreatment standards and requirements. It is the responsibility of significant industrial users to apply for and receive a permit prior to discharge, whether or not the industrial user has been identified and formally requested to do so.

(3)    If wastewaters containing any pollutant, including excess flow, or as otherwise defined in this code, are discharged or proposed to be discharged to the POTW, the City may take any action necessary to:

(i)    Prohibit the discharge of such wastewater;

(ii)    Require an industrial user to demonstrate that in-plant facility modifications will reduce or eliminate the discharge of such substances in conformity with this code;

(iii)    Require treatment, including storage facilities or flow equalization necessary to reduce or eliminate the potential for a discharge to violate this code;

(iv)    Require the industrial user making, causing or allowing the discharge to pay any additional cost or expense incurred by the City for handling, treating, disposing or remediation costs as a result of wastes discharged to the wastewater treatment system;

(v)    Require the industrial user to apply for and obtain a permit;

(vi)    Require timely and factual reports from the industrial user responsible for such discharge; or

(vii)    Take such other action as may be necessary to meet the objectives of this code.

(1)    Maximum Allowable Industrial Loading (MAIL). The City may implement local limits through allocation of the MAIL to SIUs and specific permitted non-SIUs that correspond to the uniform concentration local limits shown in the table above and are hereby incorporated by reference. The MAILs are shown in the document “Persigo Wastewater Treatment Facility, Grand Junction, CO Local Limits” dated July 24, 2019.

(e)    Surcharge. Industrial users that discharge wastewater that exceeds normal domestic strength wastewater as defined in GJMC 13.04.010 may be surcharged in accordance with adopted surcharge rates for flow, BOD5 and/or TSS (see GJMC 13.04.250). In no case shall a surcharge be allowed that causes a violation of the general or specific prohibitions or an industrial discharge permit, results in a mass-based local limit to be exceeded, causes the WWTP hydraulic or treatment capacity to be exceeded or results in a violation of a categorical pretreatment standard.

(f)    All industrial users subject to a categorical pretreatment standard shall comply with all requirements of such standard, and shall also comply with any limitations contained in this code. Where the same pollutant is limited by more than one pretreatment standard, the limitations which are more stringent shall prevail. Compliance with categorical pretreatment standards shall be in the time frame specified in the applicable categorical pretreatment standard.

(g)    The City may establish more stringent pollutant limits, additional site-specific pollutant limits, best management practices, and/or additional pretreatment requirements when, in the judgment of the City, such limitations are necessary to implement the provisions of this code.

(h)    Promulgation of Standards.

(1)    Upon the promulgation of the federal categorical pretreatment standard for a particular industrial subcategory, the federal standard, if more stringent than limitations imposed by this code for sources in that subcategory, shall immediately supersede the limitations imposed by this code as required by the applicable categorical pretreatment standard.

(2)    State requirements and limitations on discharges shall apply in any case where they are more stringent than federal pretreatment standard and pretreatment requirements or those in this code.

13.04.380 Industrial pretreatment program – Pretreatment and monitoring facilities, right of entry and search warrants.

(a)    Pretreatment and Monitoring Facilities.

(1)    Treatment Required. An industrial user shall provide necessary wastewater treatment at the industrial user’s expense as required to comply with this code and shall achieve compliance with all pretreatment standard and pretreatment requirement(s) within the time limitations specified by the EPA, the State, or the City, whichever is more stringent. Detailed plans showing the pretreatment facilities and operating procedures shall be submitted to the City Manager for review and shall be deemed acceptable by the City before construction of the facility. The review of such plans and operating procedures will in no way relieve the industrial user from the responsibility of modifying the facility as necessary to produce an effluent acceptable to the City under the provisions of this code.

(2)    Wastewater Discharge Control. The City may require an industrial user to restrict discharge during peak flow periods, designate that certain wastewater be discharged only into specified sewers, relocate and/or consolidate points of discharge, separate sewage wastestreams from industrial wastestreams, and such other conditions as may be necessary to protect the POTW and demonstrate the industrial user’s compliance with the requirements of this code.

(3)    Flow Equalization. The City may require any industrial user 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. An industrial discharge permit may be issued solely for flow equalization.

(4)    Monitoring Facilities. The City may require an industrial user to install at the industrial user’s expense, a manhole and suitable monitoring facilities or equipment that allows for the representative sampling and accurate observation of wastewater discharges and be maintained by the industrial user so as to be safe and accessible at all times. Whether constructed on public or private property, the monitoring facilities shall be constructed in accordance with the City’s requirements and all applicable construction standards and specifications. Monitoring equipment and structures shall be maintained in proper working order and kept safe and accessible at all times to City personnel. The monitoring equipment shall be located and maintained on the industrial user’s premises outside of the building unless otherwise approved by the City. When such a location would be impractical, the City may allow such facility to be constructed in the public street or easement area, with the approval of the agency having jurisdiction over such street or easement, and located so that it will not be obstructed by public utilities, landscaping or parked vehicles.

(5)    Multi-tenant Buildings. When more than one industrial user is able to discharge into a common service line, the City may require installation of separate monitoring and/or metering equipment for each industrial user.

(6)    Flow, pH and Lower Explosive Limit (LEL) Meters. If the City determines that an industrial user needs to measure and report wastewater flow and/or discharge process wastewaters necessitating continuous pH measurement and/or discharge wastewater that may contain flammable substances, they may be required to install and maintain, at the industrial user’s expense, approved meters, structures and equipment.

(7)    Unless approved by the City Manager in writing, no industrial user shall cover any manhole, sewer cleanout, or other openings in the wastewater collection system with earth, paving, or otherwise render it inaccessible.

(b)    Right of Entry.

(1)    Whenever it shall be necessary for the purposes of this code, the City may enter upon any industrial user’s facility, property or premises for the purposes of:

(i)    Performing all inspection, surveillance and monitoring procedures necessary to determine, independent of information supplied by industrial users, compliance or noncompliance with applicable pretreatment standards and pretreatment requirements by an industrial user. Compliance monitoring and inspection shall be conducted at a frequency as determined by the City and may be announced or unannounced;

(ii)    Examining and copying any records required to be kept under the provisions of this code or of any other local, State or federal regulation;

(iii)    The City may use electronic means of its choosing to photograph, videotape and/or digitally collect and preserve images and sound of any areas of any facility as deemed necessary by the City for carrying out the duties of the industrial pretreatment program including, but not limited to, documentation of the industrial user’s compliance status and for reinforcement of required written reports. The industrial user shall be allowed to review copies of data the City obtains so that the industrial user may assert confidentiality;

(iv)    Inspecting any monitoring equipment or method, pretreatment system equipment and/or operation;

(v)    Sampling any discharge of wastewater into POTW; and/or

(vi)    Inspecting any production, manufacturing, fabricating or storage area where pollutants, regulated under this code, could originate, be stored, or be discharged to the POTW.

(2)    The occupant of such property or premises shall render all proper assistance in such activities. Where an industrial user has security measures in place which require proper identification and clearance before entry into its premises, the industrial user shall make necessary arrangements with its security personnel so that authorized representatives of the City will be permitted to enter without delay to perform their specified functions.

(3)    The City Manager and other duly authorized agents and employees of the City are entitled to enter all private properties through which the City or any connecting jurisdiction holds an easement.

(4)    Failure to Allow Entry or Unreasonable Delays. In the event the City or other duly authorized representative of the City is refused admission or unreasonably delayed, it is a violation and may result in enforcement action as allowed for under this code including revocation of the industrial discharge permit.

(5)    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 industrial user at the written or verbal request of the City Manager and shall not be replaced. The costs of clearing such access shall be borne by the industrial user.

(c)    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 code, 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 code or any permit or order issued hereunder, or to protect the overall public health, safety and welfare of the community, the City Manager may, with the assistance of the City Attorney, seek issuance of a search warrant from the Grand Junction Municipal Court.

13.04.440 Industrial pretreatment program – Sample collection and analytical methods.

(a)    Sample Collection. Compliance determinations with respect to prohibitions and limitations in this code may be made on the basis of either grab or composite samples of wastewater as specified by the City. Such samples shall be taken at a point or points which the City in its sole discretion determines to be suitable for obtaining a representative sample of the discharge. Composite samples may be taken over a 24-hour period, or over a longer or shorter time span, as determined by the City to meet specific circumstances.

(b)    Sample Type. 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, and based on data that is representative of conditions occurring during the reporting period.

(1)    Except as indicated in subsection (b)(2) of this section, the industrial user must collect representative wastewater samples using 24-hour flow proportional composite sampling techniques, unless time-proportional composite sampling or grab sampling is required by the City. Where time-proportional composite sampling or grab sampling is authorized by the City, the samples must be representative of the permitted discharge. For the reports required by GJMC 13.04.450(a), the industrial user is required to collect the number of grab samples necessary to assess and assure compliance with applicable pretreatment standards and requirements.

(2)    Samples for oil and grease, temperature, pH, cyanide, total phenols, sulfides, total recoverable petroleum hydrocarbons and volatile organic compounds must be obtained using grab collection techniques. 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. Composited samples for other parameters unaffected by the compositing procedures as documented in approved EPA methodologies may be authorized by the City, as appropriate. In addition, grab samples may be required to show compliance with instantaneous local limits, including pH.

(c)    Analytical Requirements. All pollutant analysis, including sampling techniques, to be submitted as part of an industrial discharge permit application, report, permit or other analyses required under this code 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 specified and approved by the City and/or EPA.

(d)    Records shall include for all samples:

(1)    The date, exact place, method, and time of sampling and the name of the person(s) taking the samples; and

(2)    The number, size and bottle type (plastic or glass) for each analysis; and

(3)    The sample type (grab or composite); and

(4)    The date and time the sample was relinquished to and received by the testing laboratory; and

(5)    The date, time and type of sample preservative added; and

(6)    The date(s) and time analyses were performed; and

(7)    The name of the person performing the analyses; and

(8)    The analytical techniques/methods used, including method detection limits and Quality Assurance/Quality Control (QA/QC) sample results; and

(9)    Calibration and maintenance records; and

(10)    All chain-of-custody records; and

(11)    The results of such analyses.

(e)    The laboratory performing the sample analyses that certifies the validity of the sample analyses with EPA criteria required to be submitted to the City must sign and attach the following certification statement with each such lab report or information to the City:

I certify that these analyses and resulting report(s) were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly analyze all samples and accurately report the results. I further certify that all analyses were performed in accordance with methods approved for wastewater analyses under the latest version of 40 CFR Part 136. Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for analyzing the wastewater samples and generating the report(s), the analyses, report and information submitted is, to the best of my knowledge and belief, true, accurate and complete.

13.04.450 Industrial pretreatment program – Reporting and notification requirements.

(a)    Self-Monitoring Reports (SMR) for All Significant Industrial Users.

(1)    Any significant industrial user or other industrial user required by the City, subject to a federal, State, or City pretreatment standard or requirement must submit self-monitoring reports (SMR), at a frequency determined by the City but no less than once per six months, indicating the nature, concentration (e.g., minimum, average and maximum) of pollutants in the discharge which are limited by pretreatment standards and the flow (e.g., minimum, 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 industrial user must submit documentation required by the City or the pretreatment standard necessary to determine compliance status of the industrial user. All self-monitoring reports must be signed and certified in accordance with GJMC 13.04.450(g).

(2)    All wastewater samples must be representative of the industrial 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 an industrial user to keep its monitoring facility in good working order shall not be grounds for the industrial user to claim that the sample results are unrepresentative of its discharge.

(3)    If an industrial user monitors any regulated pollutant at the appropriate sampling location more frequently than required by the City, using the methods and procedures prescribed in GJMC 13.04.440, the results of this monitoring shall be included in the self-monitoring report.

(4)    The sampling and analyses required for the reporting outlined above may be performed by the City in lieu of the permittee. Where the City itself makes arrangements with the industrial user to collect all the information required for the report, the industrial user will not be required to submit the report.

(b)    Requirements for New Categorical Industrial Users.

(1)    Baseline Monitoring Reports (BMR) – Categorical Industrial Users.

(i)    Within either 180 days after the effective date of a categorical pretreatment standard, or the final administrative decision on a category determination under 40 CFR Section 403.6(a)(4), whichever is later, existing industrial users currently discharging to or scheduled to discharge to the POTW shall submit to the City a baseline monitoring report (BMR) which contains the information listed in GJMC 13.04.390(f).

(ii)    At least 90 days prior to commencement of their discharge, new sources, and sources that become categorical industrial users subsequent to the promulgation of an applicable categorical pretreatment standard, shall submit to the City a compliance report which contains the information listed in GJMC 13.04.390(f).

When the City finds that an industrial user has violated, or continues to violate, any provision of this code, an industrial discharge permit, or order issued hereunder, or any other pretreatment standard or requirement, the City may serve upon the industrial user a written notice of violation. Within 10 working days of the receipt of such notice, or at a time period specified by the City, an explanation of the violation and a plan for the satisfactory correction of prevention thereof, to include specific required actions, shall be submitted by the industrial user to the City. Submission of such a plan in no way relieves the industrial 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 to take any action, including emergency actions or any other enforcement action, without first issuing a notice of violation.

(2)    Suspension of Service.

(i)    Endangerment to Health or Welfare of the Community. The City, through other than a formal notice to the affected industrial user, may immediately and effectively halt or prevent any discharge of pollutants into any natural waterway, surface drainage within the City, any area under jurisdiction of the City, the POTW of the City or any wastewater system tributary thereto, by any means available to them, including physical disconnection from the wastewater system, whenever it reasonably appears that such discharge presents an imminent endangerment to the health or welfare of the community.

(ii)    Endangerment to Environment or Treatment Works. The City, after written notice to the discharger may halt or prevent any discharge of pollutants into any natural waterway, surface drainage within the City, any area under jurisdiction of the City, the POTW, wastewater system tributary thereto, by any means available to them, including physical disconnection from the wastewater system, whenever such discharge presents or may present an endangerment to the environment or threatens to interfere with the operation of the POTW.

(iii)    Any industrial user notified of a suspension of the wastewater treatment service and/or revocation of an industrial discharge permit shall immediately stop or eliminate the contribution. In the event of a failure of the person to comply voluntarily with the suspension order, the City shall take such steps as deemed necessary including immediate severance of the sewer connection, to prevent or minimize damage to the POTW system or endangerment to individuals or the environment. The City may reinstate the industrial discharge permit and/or the wastewater treatment service upon proof of the elimination of the noncomplying discharge.

A detailed written statement submitted by the industrial user describing the causes of the harmful contribution and the measure taken to prevent any future occurrence shall be provided to the City within five days of the date of occurrence. Suspension of service shall not be a bar against, or a prerequisite for, taking any other action against the industrial user.

(3)    Administrative Order. When the City finds that an industrial user has violated, or continues to violate, any provision of this code, an industrial discharge permit, or order issued hereunder, or any other pretreatment standard or requirement, the City may issue an administrative order to the industrial user responsible for the discharge directing that the industrial user come into compliance within a specific time. If the industrial user does not come into compliance within the time provided, sewer service may be discontinued unless and until adequate treatment facilities, devices, or other related appurtenances are installed and properly operated. An order 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 POTW. An administrative order may not extend the deadline for compliance established for a pretreatment standard or requirement, nor does an administrative order relieve the industrial user of liability for any violation, including any continuing violation. Issuance of an administrative order shall not be a bar against, or a prerequisite for, taking any other action against the industrial user.

(4)    Consent Order. The City may enter into a consent order, assurances of compliance, or other similar documents establishing an agreement with any industrial user responsible for noncompliance. Such documents shall include specific actions to be taken by the industrial user to correct the noncompliance within a time period specified by the document. A consent order may include penalties, supplemental environmental projects, or other conditions and requirements as agreed to by the City and the industrial user. Issuance of a consent order shall not be a bar against, or a prerequisite for, taking any other action against the industrial user.

(5)    Cease and Desist Order.

(i)    When the City Manager finds that an industrial user has violated, or continues to violate, any provision of this code, an industrial discharge permit, an order issued hereunder or any other pretreatment standard or requirement, or that the industrial user’s past compliance history indicates that violations are likely to recur, the City Manager may issue an order to the industrial user directing it to cease and desist all such violations and directing the industrial user to:

(A)    Immediately comply with all requirements;

(B)    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.

(ii)    Issuance of a cease and desist order shall not be a bar against, or a prerequisite for, taking any other action against the industrial user.

(6)    Administrative Fines.

(i)    When the City finds that an industrial user has violated, or continues to violate, any provision of this code, an industrial discharge permit, order issued hereunder, or any other pretreatment standard or requirement, the City may fine such industrial user in an amount not to exceed $10,000 per day per violation. 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.

(ii)    A lien against the industrial user’s property shall be sought for unpaid charges, fines, and penalties.

(iii)    Industrial users desiring to appeal such fines must file a written request for the City to reconsider the fine along with full payment of the fine amount within 10 days of being notified of the fine. Such notice or appeal shall set forth the nature of the order or determination being appealed, the date of such order or determination, the reason for the appeal, and request a hearing pursuant to procedures outlined in subsections (h) and (i) of this section.

(iv)    Issuance of an administrative fine shall not be a bar against, or prerequisite for, taking any other action against the industrial user.

(d)    Judicial Enforcement Remedies.

(1)    Injunctive Relief. When the City finds that an industrial user has violated, or continues to violate, any provision of this code, an industrial discharge permit, or order issued hereunder, or any other pretreatment standard or requirement, the City may petition a court of competent jurisdiction for the issuance of a temporary or permanent injunction, as appropriate, which restrains or compels the specific performance of the industrial discharge permit, order, or other requirement imposed by this code on activities of an industrial user. The City may also seek such other action as is appropriate for legal and/or equitable relief, including a requirement for the industrial 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 an industrial user.

(2)    Civil Penalties.

(i)    An industrial user who has violated, or continues to violate, any provision of this code, an industrial discharge permit, or order issued hereunder, or any other pretreatment standard or requirement shall be liable to the City for a maximum civil penalty not to exceed $10,000 per day per violation. In the case of a monthly or other long-term average discharge limit, penalties shall accrue for each day during the period of violation.

(ii)    The City may recover reasonable attorneys’ fees (including the value of in-house counsel), 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.

(iii)    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 industrial user’s violation, corrective actions by the industrial user, the compliance history of the industrial user, and any other factor as justice requires.

(iv)    Actions for civil penalties shall be civil actions brought in the name of the City. The City must prove alleged violations by a preponderance of the evidence.

(v)    Filing a suit for civil penalties shall not be a bar against, or a prerequisite for, taking any other action against an industrial user.

(3)    Civil/Administrative Fine Pass Through. In the event that an industrial user discharges such pollutants which cause the City to violate any condition of its CPDS permit and the City is fined by the EPA or the State for such violation, then such industrial user shall be fully liable for the total amount of the fine assessed against the City by the EPA and/or the State.

(4)    Criminal Prosecution.

(i)    Any industrial user that willfully or negligently violates any provision of this code, any orders or an industrial discharge permit issued hereunder, or any other pretreatment standard or requirement shall, upon conviction, be guilty of a misdemeanor, punishable by a fine not to exceed $25,000 and be subject to imprisonment for not more than one year or both. Each day in which any such violation occurs or persists shall be deemed a separate and distinct offense.

(ii)    Any industrial user that 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 code, an industrial discharge permit or order, or who falsifies, tampers with or knowingly renders inaccurate any monitoring device or method required under this code shall, upon conviction, be punishable by a fine not to exceed $25,000 and be subject to imprisonment for not more than one year, or both. In addition, these penalties may be sought for any person who maliciously, willfully, or negligently breaks, destroys, uncovers, defaces, tampers with, or otherwise destroys, or who prevents access to, any structure, appurtenance or equipment, or any part to the POTW. Each day in which any such violation occurs or persists shall be deemed a separate and distinct offense.

(iii)    The City may refer violations that warrant criminal prosecution to the U.S. Attorney General’s Office, State Attorney General’s Office or USEPA Criminal Investigation Division or other appropriate agency. This referral shall not preclude the City from taking a parallel administrative or civil enforcement action.

(iv)    Upon proof of willful or intentional meter bypassing, meter tampering, or unauthorized metering, the City shall be entitled to recover as damages three times the amount of actual damages in addition to any other penalties assessed.

(e)    Remedies Nonexclusive. The remedies provided for in this code are not exclusive of any other remedies that the City may have under the provisions of Colorado law. The City may take any, all, or any combination of these actions against a noncompliant industrial user. Enforcement of pretreatment violations will generally be in accordance with the enforcement response plan. However, the City may take other action against any industrial user when the circumstances warrant and may take more than one enforcement action against any noncompliant industrial user.

(f)    Public Nuisance. Any violation of this code, an industrial discharge permit, or order issued hereunder, is hereby declared a public nuisance and shall be corrected or abated as directed by the City Manager or their designee. Any person(s) creating a public nuisance shall be subject to the provisions of GJMC 8.08.010 governing such nuisances, including reimbursing the City for any costs incurred in removing, abating, or remedying said nuisance.

(g)    Duty to Halt or Reduce Activity. Upon reduction of efficiency of operation, or loss or failure of all or part of the pretreatment equipment, the permittee shall, to the extent necessary to maintain compliance with its permit, control its production or discharges (or both) until operation of the treatment facility is restored or an alternative method of treatment is provided. This requirement applies, for example, when the primary source of power of the pretreatment equipment fails or is reduced. It shall not be a defense for a permittee in an enforcement action that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the conditions of its permit.

(h)    Administrative Appeal Procedure. An industrial user may appeal the issuance of an administrative order and/or administrative fine within 10 working days of issuance of the administrative order or fine. Such appeal shall be filed with the City Manager and include written documentation setting forth in detail the factual and legal basis for the appeal by the industrial user. The City Manager shall review the appeal within 10 working days of receipt. The City Manager may request further information from the industrial user and/or City staff. The City Manager may, after review of the information, issue an order requiring the industrial user to comply, require modification to the existing enforcement action or hold a show cause hearing as specified in subsection (i) of this section. The enforcement action and/or fine shall remain in effect and fully enforceable during this administrative review process.

(i)    Show Cause Hearing.

(1)    The City Manager is authorized to order any industrial user who violates any pretreatment standard or requirement, an industrial discharge permit, an enforcement action or any provision of this code to show cause why appropriate enforcement action should not be taken. In such case, a notice shall be served on the industrial user specifying the time and place of a hearing regarding the violation, the reasons why the action is to be taken, the proposed enforcement action, and directing the industrial user to show cause why the proposed enforcement action should not be taken.

(2)    The notice of the hearing shall be served upon the industrial user personally or by certified mail, return receipt requested, at least 10 working days before the hearing. Service may be made on any agent or the authorized representative of the industrial user.

(3)    The City Manager may conduct the hearing or may appoint a hearing officer or may instead convene a utility hearing board to conduct the hearing. The board shall consist of a City Council member or designee, the City Manager, a County Commissioner or designee, an employee of the Department of Public Works, Utilities and Planning, and a connector district representative if the appellant or respondent industrial user is located within the jurisdiction of that district.

(4)    The Hearing Officer or Utility Hearing Board shall have the power to:

(i)    Issue in the name of the City Council notices of hearings requiring the attendance and testimony of witnesses and the production of evidence.

(ii)    Hold a quasi-judicatory hearing, and receive relevant evidence relating to compliance with the requirements set forth in this code. Hearings shall be conducted informally. Rules of civil procedure and evidence shall not solely determine the conduct of the hearing or the admissibility of evidence. All testimony shall be given under oath, and a tape recording or other evidence of the verbatim content of the hearing shall be made. The burden of persuasion shall be upon the industrial user. The standard of proof to be utilized by the City Manager or Utility Hearing Board in making its findings or recommendations shall be a preponderance of the evidence.

(iii)    Determine and find whether just cause exists for not taking the proposed enforcement actions, or whether the order or action appealed is unwarranted.

(iv)    Transmit a report of the evidence and hearing, including transcripts, tapes, and copies of other evidence requested by any party, together with findings and recommendations to all parties to the hearing and to the City Council.

(5)    Effect of Hearing.

(i)    Findings and recommendations of the City Manager or Utility Hearing Board shall be final and binding upon the City Manager and parties to the hearing; provided, however, that if the City Council disapproves the recommendations of the City Manager or Utility Hearing Board within 30 days thereof, the City Council may conduct its own hearing, make its own findings, and issue its own orders.

(ii)    An order consistent with findings and recommendations of the City Manager or Utility Hearing Board, or the City Council, as the case may be, shall be issued by the City Manager. The order may direct that sewer service to the industrial user responsible for the violation be discontinued unless and until adequate treatment facilities or related devices have been installed and approved within a specified period of time and in compliance with all local, State and federal statutes and regulations. The order may provide for imposition of appropriate charges for the cost to the City of the enforcement action, applicable liquidated damages and administrative fines. Further orders and directives, as are necessary and appropriate to enforce industrial discharge permits and provisions of this code, may be issued by the City Manager.

13.04.490 Industrial pretreatment program – Pretreatment authority outside of City.

(a)    In order to achieve and maintain compliance with the Clean Water Act, federal pretreatment standards and requirements, State regulations, sewage grant conditions, and WWTP discharge permit requirements, the City, as manager/operator of the Persigo WWTP, must possess and demonstrate a clear legal right to require compliance with pretreatment standards and requirements by any industrial user of the POTW located outside of the City’s territorial jurisdiction. To that end, all governmental sewage connectors, including sanitation districts and the County, have been requested to adopt, and have adopted, by resolution, a regulatory pretreatment program either parallel to the one established by this code or have incorporated by reference the provisions of this code.

(b)    The connector districts and the County shall also be requested to approve necessary revisions to existing sewer service agreements, joint agreements or enter into an industrial pretreatment program-only agreement granting the City the right to administer and enforce the connector’s pretreatment program on behalf of and as agent for the connector district or County.

13.04.500 Industrial pretreatment program – Affirmative defenses to discharge violations.

(a)    Upset.

(1)    For the purposes of this code, 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 industrial user. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventative 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 subsection (a)(3) of this section are met.

(3)    An industrial user who wishes to establish the affirmative defense of upset shall demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that:

(i)    An upset occurred and the industrial user can identify the cause(s) of the upset;

(ii)    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

(iii)    The industrial user has submitted the following information to the City within 24 hours of becoming aware of the upset. If this information is provided orally, a written submission must be provided within five days:

(A)    A description of the indirect discharge and cause of noncompliance;

(B)    The period of noncompliance, including exact dates and times or, if not corrected, the anticipated time the noncompliance is expected to continue; and

(C)    Steps being taken and/or planned to reduce, eliminate and prevent recurrence of the noncompliance.

(4)    In any enforcement proceeding, the industrial user seeking to establish the occurrence of an upset shall have burden of proof.

(5)    Industrial users shall 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)    Industrial users shall control (decrease) 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. An industrial user shall have an affirmative defense to an enforcement action brought against it for noncompliance with the specific prohibitions in any action brought against it alleging a violation of the specific prohibitions in GJMC 13.04.370(b)(3), (4), (5), (6) or (7) where the industrial user demonstrates that:

(1)    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

(2)    The industrial user had accurately disclosed the concentration of the pollutant(s) causing the pass through or interference in applications, reports, or other required documents as required; and either:

(i)    A local limit designed to prevent pass through and/or interference, as the case may be was developed for each pollutant in the industrial user’s discharge that caused pass through or interference, and the industrial user was in compliance with each such local limit directly prior to and during the pass through or interference; or

(ii)    If a local limit designed to prevent pass through and/or interference, as the case may be, has not been developed for the pollutant(s) that caused the pass through or interference, the industrial user’s discharge directly prior to and during the pass through or interference did not change substantially in nature or constituents from the industrial user’s prior discharge activity when the POTW was regularly in compliance with the POTW’s CPDS permit requirements and, in the case of interference, applicable requirements for sewage sludge use or disposal.

(c)    Bypass.

(1)    For purposes of this subsection:

(i)    Bypass means the intentional diversion of wastestreams from any portion of an industrial user’s treatment facility.

(ii)    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)    Bypass Not Violating Applicable Pretreatment Standards or Requirements. An industrial 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 subsections (c)(3) and (4) of this section but are reportable under GJMC 13.04.450(a), (c), (d), (i) and (j), as appropriate.

(3)    Notice.

(i)    If an industrial user knows in advance of the need for a bypass, it shall submit prior notice to the City Manager, if possible, at least 10 days before the date of the bypass.

(ii)    An industrial user shall submit oral notice of an unanticipated bypass that exceeds applicable pretreatment standards to the City Manager within 24 hours from the time the industrial user becomes aware of the bypass. A written submission shall also be provided within five days of the time the industrial 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.

(4)    Prohibition of Bypass.

(i)    Bypass is prohibited, and the City Manager may take enforcement action against an industrial user for a bypass, unless:

(A)    Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage;

(B)    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 preventative maintenance; and

(C)    The industrial user submitted notices as required under subsection (c)(3) of this section.

(ii)    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 subsection (c)(4)(i) of this section.
