These limits are based upon installation of air stripping technology as described in the EPA document: “Model NPDES Permit for Discharges Resulting from the Cleanup of Gasoline Released from Underground Storage Tanks. June 1989.”

Further Standards and Limitations 1. Best management practices (BMPs). The General Manager or designee may develop best management practices (BMPs) to implement the requirements of section 6.4 of these Rules and Regulations. Pursuant to 40 CFR § 403.5(c)(4), such BMPs shall be considered local limits and Pretreatment Standards for the purposes of this Article and Section 307(d) of the Act. The CWSD may establish sector control programs based on BMPs to control specific Pollutants as necessary to meet the requirements of this Article for Users that engage in similar activities and discharge similar Pollutants. The CWSD may establish policies for sector control programs as necessary to supplement the requirements included in this Article and Users subject to these sector control programs must comply with these policies. Users subject to sector control programs may be required to install and operate Wastewater treatment systems and/or implement BMPs and may be required to apply for a Wastewater discharge Permit in accordance with section 6.6 of this Article. 2. Categorical Pretreatment Standards. Users must comply with the Categorical Pretreatment Standards found at 40 CFR chapter I, subchapter N, parts 405-471. Upon the promulgation of the Categorical Pretreatment Standard for a particular industrial subcategory, developed pursuant to federal statutes or regulations, the Categorical Pretreatment Standard if more stringent than limitations imposed in this Article shall immediately supersede the limitations imposed in this Article. a) Where a Categorical Pretreatment Standard is expressed only in terms of either the mass or the concentration of a Pollutant in Wastewater, the General Manager or designee may impose equivalent concentration or mass limits in accordance with Sections 6.4(E)** and 6.4(E)** of this Article and 40 CFR § 403.6(c). b) When the limits in a Categorical Pretreatment Standard are expressed only in terms of mass of Pollutant per unit of production, the General Manager or designee 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 in accordance with 40 CFR § 403.6(c)(2). c) When Wastewater subject to a Categorical Pretreatment Standard is mixed with

October 30, 2023

Wastewater not regulated by the same standard, the General Manager or designee shall impose an alternate limit in accordance with 40 CFR § 403.6(e). d) When a Categorical Pretreatment Standard is expressed only in terms of Pollutant concentrations, an Industrial User may request that the CWSD convert the limits to equivalent mass limits. The determination to convert concentration limits to mass limits is within the discretion of the General Manager or designee. The CWSD may establish equivalent mass limits only if the User meets all the conditions set forth in Section 6.4(E)(i)(a)-(e) below. i.

To be eligible for equivalent mass limits, the User must: a. Employ, or demonstrate that it will employ, water conservation methods and technologies that substantially reduce water use during the term of its individual Wastewater discharge Permit; b. 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; c. 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 condition; d. 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 e. Have consistently complied with all applicable Categorical Pretreatment Standards during the period prior to the User’s request for equivalent mass limits.

ii.

A User subject to equivalent mass limits must: a. Maintain and effectively operate control and treatment technologies adequate to achieve compliance with the equivalent mass limits; b. Continue to record the facility's flow rates through the use of a continuous effluent flow monitoring device; c. Continue to record the facility's production rates and notify the CWSD General Manager or designee whenever production rates are expected to vary by more than 20 percent from its baseline production rates determined in subsection (E)(2)(i)(c) in this section. Upon notification of a revised production rate, the General Manager or designee will reassess the equivalent mass limit and revise the limit as necessary to reflect changed conditions at the facility; and d. Continue to employ the same or comparable water conservation methods and technologies as those implemented pursuant to subsection (E)(2)(i)(a) of this section so long as it discharges under

October 30, 2023

an equivalent mass limit. iii.

When developing equivalent mass limits, the General Manager or designee: a. Will calculate the equivalent mass limit by multiplying the actual average daily flow rate of the regulated process(es) of the Industrial User by the concentration-based daily maximum and monthly average standard for the applicable Categorical Pretreatment Standard and the appropriate unit conversion factor; b. 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 c. May retain the same equivalent mass limit in subsequent individual Wastewater discharge Permit terms if the 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 6.4(E)(1). The User must also be in compliance with § 403.17 regarding the prohibition of bypass.

(e) The General Manager or designee may convert the mass limits of the Categorical Pretreatment Standards of 40 CFR parts 414, 419, and 455 to concentration limits for purposes of calculating limitations applicable to individual Industrial Users. The conversion is at the discretion of the General Manager or designee. (f) Once included in its Permit, the User must comply with the equivalent limitations developed in section 6.4(E)(1)) in lieu of the promulgated Categorical standards from which the equivalent limitations were derived. (g) Many Categorical Pretreatment Standards specify one limit for calculating maximum daily discharge limitations and a second limit for calculating maximum monthly average, or four-day average, limitations. Where such standards are being applied, the same production or flow figure shall be used in calculating both the average and the maximum equivalent limitation. (h) Any User operating under a Permit incorporating equivalent mass or concentration limits calculated from a production-based standard shall notify the General Manager or designee within two 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 General Manager or designee of such anticipated change will be required to meet the mass or concentration limits in its Permit that were based on the original estimate of the long term average production rate. 3. Specific Pollutant Limitation. No person shall discharge Wastewater containing in excess of the limitations on discharges as set forth in this Article. October 30, 2023

4. Other Requirements. State requirements and limitations on discharges shall apply in any case where they are more stringent than federal requirements and limitations or those contained in this Article. The CWSD’s limitations or requirements on discharges shall apply in any case where they are more stringent than state or federal requirements or limitations. 5. CWSD Right of Revision. The CWSD reserves the right to establish more stringent limitations or requirements on discharges to the POTW if deemed necessary to comply with the objectives presented herein. 6. Dilution. No User shall ever increase the use of water, or in any way attempt to dilute a discharge as a partial or complete substitute for adequate treatment to achieve compliance with the limitations contained in the Categorical Pretreatment Standards, or in any other specific Pollutant limitation developed by the CWSD or state. The General Manager or designee may impose mass limitations on Users who are using dilution to meet applicable Pretreatment Standards or requirements. Section 6.5

Pretreatment and Monitoring Facilities

Treatment Required: An Industrial User shall provide necessary Wastewater treatment at the Industrial User's expense as required to comply with this Article and shall achieve compliance with all Pretreatment Standards and Requirements within the time limitations specified by the EPA, the State, or CWSD, whichever is more stringent. Detailed plans showing the pretreatment facilities and operating procedures shall be submitted to the General Manager for review and shall be acceptable 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 CWSD under the provisions of this Article.

Wastewater Discharge Control: CWSD 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 Article.

Flow Equalization: CWSD may require any Industrial User discharging into the POTW to install and maintain, on their property and at their expense, a suitable storage and flowcontrol facility to ensure equalization of flow. An Industrial Discharge Permit may be issued solely for flow equalization.

Monitoring Facilities: CWSD may require an Industrial User to install at the Industrial User’s expense, suitable monitoring facilities or equipment that allows for the representative sampling and accurate observation of Wastewater discharges. Monitoring equipment and structures shall be maintained in proper working order and kept safe and

October 30, 2023

accessible at all times to CWSD personnel. The monitoring equipment shall be located and maintained on the Industrial User's premises outside of the building unless otherwise approved by CWSD. When such a location would be impractical, CWSD 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. When more than one Industrial User is able to discharge into a common service line, CWSD may require installation of separate monitoring equipment for each Industrial User. E.

Flow, pH and LEL Meters: If CWSD determines that an Industrial User needs to measure and report Wastewater flow, discharge process Wastewaters necessitating continuous pH measurement or discharge Wastewater that may contain flammable substances may be required to install and maintain, at the Industrial User’s expense, approved meters, structures and equipment.

Additional Pretreatment Measures. 1. Grease interceptors shall be required for all food preparation establishments (including, but not limited to, cafes, fast food outlets, pizza outlets, delicatessens, sandwich shops, coffee shops), food processing establishments, food manufacturing establishments, animal slaughter houses, soap factories, tallow/fat rendering establishments, hide curing establishments, schools, nursing homes and other establishments when, in the opinion of the General Manager or designee, they are necessary for the proper handling of Wastewater containing excessive amounts of grease and oil; except that such interceptors shall not be required for residential Users. a) All grease interceptors shall be of type and capacity approved by the General Manager or designee and shall be so located to be easily accessible for cleaning and inspection. b) Such interceptors shall be inspected, cleaned, and repaired by the User at the User's expense. c) Grease interceptors shall be cleaned as often as necessary to ensure that sediment and floating materials do not accumulate to impair the efficiency of the grease interceptor; that the discharge is in compliance with Local Limits and, to ensure that no visible grease is observed in the discharge. Grease interceptors shall be completely evacuated at a minimum of every three months, or more frequently when: i. Twenty-five percent or more of the wetted height of the grease trap or grease interceptor, as measured from the bottom of the device to the invert of the outlet pipe, contains floating materials, sediment, oils or greases; ii. The discharge exceeds BOD, COD, TSS, FOG, pH, or other Pollutant levels established by the CWSD; or iii. If there is a history of noncompliance. d) The General Manager or designee may require a business to maintain a specific grease interceptor pumping and cleaning interval based on observed problems or noncompliance related FOG production, accumulation and Wastewater discharges. The General Manager or designee may allow a business to request a cleaning frequency greater than every three months. The business shall submit a

October 30, 2023

2. 3.

significant Industrial User that has filed a timely application pursuant to subsection (B) of this section may continue to discharge for the time period specified therein. The General Manager or designee may require other Industrial Users to obtain discharge Permits as necessary to carry out the provisions of this Article. Any violation of the terms and conditions of a Wastewater discharge Permit shall be deemed a violation of this Article and subjects the User to the sanctions set out in section 6.18 of this Article. Obtaining a Wastewater discharge Permit does not relieve a User of its obligation to comply with all federal and state Pretreatment Standards and requirements or with any other requirements of federal, state and local law.

Permits Required. All Significant Industrial Users proposing to connect to, or discharge into, any part of the Wastewater system shall apply for and obtain an Industrial Wastewater Discharge Permit prior to commencing discharge to the POTW. A separate Permit may be required for each Industrial User, building or complex of buildings. The discharge of Wastewater to the POTW without a valid Permit from a Significant Industrial User shall be a violation of this Article. Such Significant Industrial Users shall immediately contact CWSD and obtain a Permit for discharge.

New Industrial Users: Applying for an Industrial Wastewater Discharge Permit. Any Industrial User required to obtain an Industrial Wastewater Discharge Permit who proposes to begin or recommence discharging into the POTW must apply for and obtain such Permit prior to the beginning or recommencing of such discharge. The Industrial User shall file a Permit application on forms provided by CWSD containing the information specified in Section 6.6, F below. The completed application for the Industrial Wastewater Discharge Permit must be filed at least ninety (90) days prior to the date upon which any discharge will begin or recommence.

Existing Industrial Users: Applying for an Industrial Wastewater Discharge Permit Reissuance. An Industrial User with an expiring Industrial Wastewater Discharge Permit shall apply for a new Permit by submitting a complete Permit application at least ninety (90) days prior to the expiration of the Industrial User’s existing discharge Permit. The Industrial User shall file a Permit application on forms provided by CWSD containing the information specified in 6.6, F below. An Industrial User with an existing Permit that has filed a complete and timely application may continue to discharge as approved by CWSD through an administrative extension of the existing Permit.

Other Industrial Users. CWSD may require other Non-Significant Industrial Users to obtain Wastewater discharge Permits necessary to carry out the purposes of this Article. CWSD may issue a zero discharge Permit to prohibit the discharge of some or all Non-

October 30, 2023

Domestic process Wastewater from an Industrial User. E.

Enforceability. Any violation of the terms and conditions of an Industrial Wastewater Discharge Permit, failure to apply for a Permit as required, or discharging without a required Permit shall be deemed a violation of this Article and subjects the Industrial User to enforcement by CWSD.

Section 6.13 A.

Sample Collection and Analytical Methods

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

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 subparagraphs 2. and 3. below, the Industrial User must

October 30, 2023

collect representative Wastewater samples using twenty-four (24) hour flow proportional composite sampling techniques, unless time-proportional composite sampling or grab sampling is required by CWSD. Where time-proportional composite sampling or grab sampling is authorized by CWSD, the samples must be representative of the permitted discharge. 2.

Samples for oil and grease, temperature, pH, cyanide, total phenols, sulfides, 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 twentyfour (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 CWSD, as appropriate. In addition, grab samples may be required to show compliance with instantaneous local limits, including pH.

3. For sampling required in support of Baseline Monitoring and 90-day Compliance reports required in Section 6.14, 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 representative sampling data do not exist. Where historical data are available, CWSD may authorize a lower minimum. For the reports required by Section 6.14, 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. 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 Article 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 CWSD or other parties approved by the EPA.

Section 6.14 A.

Reporting Requirements.

Periodic Compliance Reports – All Significant Industrial Users.

October 30, 2023

Any Industrial User subject to a federal, state, or CWSD Pretreatment Standard or Requirement must, at a frequency determined by CWSD submit no less than once per six (6) months, unless required more frequently in the Permit or by CWSD, reports indicating the nature, concentration of Pollutants in the discharge which are limited by Pretreatment Standards and the average and maximum daily flows for the reporting period. In cases where the Pretreatment Standard requires compliance with a Best Management Practices (BMPs) or pollution prevention alternatives, the Industrial User must submit documentation required by CWSD or the Pretreatment Standard necessary to determine compliance status of the Industrial User. All periodic compliance reports must be signed and certified in accordance with Section 6.14, H.

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.

If an Industrial User subject to the reporting requirement in this section monitors any regulated Pollutant at the appropriate sampling location more frequently than required by CWSD, using the methods and procedures prescribed in Section 6.13, the results of this monitoring shall be included in the report.

4. B.

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

Within either one hundred eighty (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 CWSD a report which contains the information listed in paragraph 2. below. At least ninety (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 Standard, shall submit to CWSD a report which contains the information listed in paragraph 2. below. A New Source shall report the method of pretreatment it intends to use to meet applicable Pretreatment Standards. A New Source also shall give estimates of its anticipated flow and quantity of Pollutants to be discharged from regulated process streams and other non-process streams.

Industrial Users described above shall submit the information set forth below.

October 30, 2023

All information required in Section 6.6,F.

Measurement of Pollutants. i.

The Industrial User shall take a minimum of one (1) representative sample to compile the data necessary to comply with the requirements of this paragraph.

ii.

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 Industrial User should measure the flows and concentrations necessary to allow use of the combined wastestream formula in 40 Section 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 Section 403.6(e) this adjusted limit along with supporting data shall be submitted to CWSD.

iii.

Sampling and analysis shall be performed in accordance with Section 6.13.

iv.

CWSD may allow the submission of a BMR which utilizes only historical data so long as the data provides information sufficient to determine the need for industrial pretreatment measures.

The BMR 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.

vi.

Signature and Report Certification. All baseline monitoring reports must be signed in accordance with Section 6.14, H. and signed by an Authorized Representative as defined in Article 2.

90-Day Compliance Reports – Categorical Industrial Users. 1.

New Sources: All New Sources subject to existing Categorical Pretreatment Standards shall submit a report to CWSD within ninety (90) days from the date of first discharge to the POTW demonstrating actual and continuing compliance with those Standards.

CWSD shall publish annually, in a newspaper of general circulation that provides meaningful public notice within the jurisdictions served by the POTW, a list of the Significant Industrial Users which, at any time during the previous twelve (12) months, were in Significant Noncompliance as defined in Article 2 with applicable Pretreatment Standards and Requirements. In addition, any Industrial User found to be in Significant Noncompliance with Article 2, Significant Noncompliance (SNC), paragraphs C, D, or H shall also be published in the newspaper.

Administrative Enforcement Actions. 1.

Notice of Violation (NOV). When CWSD finds that an Industrial User has violated, or continues to violate, any provision of this Article, an Industrial Wastewater Discharge Permit, or order issued hereunder, or any other Pretreatment Standard or Requirement, CWSD may serve upon the Industrial User a written Notice of Violation. Within five (5) working days of the receipt of such notice, 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 CWSD. 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 CWSD to take any action, including emergency actions or any other enforcement action, without first issuing a Notice of Violation.

Suspension of Service. CWSD may suspend the Wastewater treatment service and/or revoke an Industrial Wastewater Discharge Permit (Section 6.9) when such revocation is necessary, in the opinion of CWSD, in order to stop an actual or threatened discharge which presents or may present an imminent or substantial endangerment to the health or welfare of persons, to the environment, causes Pass Through or Interference or causes CWSD to violate any condition of its CDPS Permit.

October 30, 2023

Any person notified of a suspension of the Wastewater treatment service and/or the Industrial Wastewater 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, CWSD 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. CWSD may reinstate the Industrial Wastewater Discharge Permit and/or the Wastewater treatment service upon proof of the elimination of the non-complying 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 CWSD within five (5) days of the date of occurrence. 3.

Administrative Compliance Order. When CWSD finds that an Industrial User has violated, or continues to violate, any provision of this Article, an Industrial Wastewater Discharge Permit, or order issued hereunder, or any other Pretreatment Standard or Requirement, CWSD may issue an 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 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 Industrial 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 Industrial User.

Consent Orders. CWSD may enter into Consent Orders, 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 CWSD and the Industrial User.

Show Cause Hearing. a.

October 30, 2023

CWSD may order any Industrial User who causes or allows an 61

unauthorized discharge to enter the POTW to show cause before the Board why the proposed enforcement action should not be taken. A notice shall be served on the Industrial User specifying the time and place of a hearing to be held by the Board regarding the violation, the reasons why the proposed action is to be taken, and directing the Industrial User to show cause before the Board why the proposed enforcement action should not be taken. The notice of the hearing shall be served personally or be sent by registered or certified mail (return receipt requested) at least ten (10) days before the hearing.

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.

A lien against the Industrial User’s property shall be sought for unpaid charges, fines, and penalties.

Industrial Users desiring to appeal such fines must file a written request for CWSD to reconsider the fine along with full payment of the fine amount within fifteen (15) 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 Section 6.18, C.5.

Issuance of an administrative fine shall not be a bar against, or prerequisite for, taking any other action against the Industrial User.

Judicial Enforcement Remedies. 1.

Injunctive Relief. When CWSD finds that an Industrial User has violated, or continues to violate, any provision of this Article, an Industrial Wastewater Discharge Permit, or order issued hereunder, or any other Pretreatment Standard or Requirement, CWSD may petition the Douglas County District Court for the issuance of a temporary or permanent injunction, as appropriate, which restrains or compels the specific performance of the Industrial Wastewater Discharge Permit, order, or other requirement imposed by this Article on activities of an Industrial User. CWSD 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.

Civil Penalties. a.

October 30, 2023

An Industrial User who has violated, or continues to violate, any provision of this Article, an Industrial Wastewater Discharge Permit, or order issued hereunder, or any other Pretreatment Standard or Requirement shall be 63

liable to CWSD for a maximum civil penalty not to exceed one thousand dollars ($1,000) 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.

CWSD 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 CWSD.

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.

Actions for civil penalties shall be civil actions brought in the name of CWSD. Such actions shall be administered pursuant to the Rules of County Court Civil Procedure, except Rules 313, 338, 339, 347, 348, 351.1, 365 and 398 shall not apply. All trials shall be to the court and all trials shall be held within CWSD. CWSD must prove alleged violations by a preponderance of the evidence.

Filing a suit for civil penalties shall not be a bar against, or a prerequisite for, taking any other action against an Industrial User.

Civil Fine Pass Through. In the event that an Industrial User discharges such Pollutants which cause CWSD to violate any condition of its CDPS Permit and CWSD 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 CWSD by the EPA and/or the State.

Criminal penalties. No Person shall dispose of Harmful Wastes or Wastewater or use the CWSD's sanitary sewers or POTW or cause the disposal of Harmful Waste or Wastewater to be done contrary to or in violation of any provisions of this Article. Any person violating any of the provisions of this Article or any Permit issued hereunder shall be deemed guilty of a separate offense for each and every day or portion thereof during which any such violation occurs and shall be punished by a fine not exceeding the maximum fine set forth in this Article, or by imprisonment not exceeding 90 days per violation, or by both such fine and imprisonment. Such penalties shall be in addition to any administrative remedies or such other liabilities provided for in this Article.

October 30, 2023

Remedies Nonexclusive. The remedies provided for in this Article are not exclusive of any other remedies that CWSD may have under the provisions of Colorado law. CWSD 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, CWSD 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.

Section 6.19 A.

Affirmative Defenses to Discharge Violations.

Upset. 1.

For the purposes of this Article, 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.

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.

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: a.

An upset occurred and the Industrial User can identify the cause(s) of the upset;

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

The Industrial User has submitted the following information to CWSD 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):

October 30, 2023

A description of noncompliance;

the

Indirect

Discharge

and

cause

ii.

The period of noncompliance, including exact dates and times or, if not corrected, the anticipated time the noncompliance is 65

expected to continue; and iii.

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

In any enforcement proceeding, the Industrial User seeking to establish the occurrence of an upset shall have burden of proof.

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.

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.

Prohibited Discharge Standards. An Industrial User shall have an affirmative defense to an enforcement action brought against it for noncompliance with the general and specific prohibitions in Section 6.4 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:

A local limit exists for each Pollutant discharged and the Industrial User was in compliance with each limit directly prior to, and during, the Pass Through or Interference; or

No local limit exists, but the discharge did not change substantially in nature or constituents from the Industrial User’s prior discharge when CWSD was regularly in compliance with its CDPS Permit, and in the case of Interference, was in compliance with applicable Sludge use or disposal requirements; or

The Industrial User disclosed the Pollutants causing the violation in the Wastewater Permit Application.

Bypass 1.

For the purposes of this Subsection: a.

October 30, 2023

Bypass means the intentional diversion of wastestreams from any portion 66

of an Industrial 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. 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 paragraphs 3. and 4. of this Section but are reportable under Section 6.14, paragraphs A, D, F, J and K, as appropriate. Notice. a.

If an Industrial User knows in advance of the need for a bypass, it shall submit prior notice to the Director, if possible, at least ten (10) days before the date of the bypass.

An Industrial User shall submit oral notice of an unanticipated bypass that exceeds applicable Pretreatment Standards to the Director within twenty four (24) hours from the time the Industrial User becomes aware of the bypass. A written submission shall also be provided within five (5) 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. The Director may waive the written report on a case-by-case basis if the oral report has been received within twenty four (24) hours.

Prohibition of Bypass. a.

Bypass is prohibited, and the Director may take enforcement action against an Industrial User for a bypass, unless; i. ii.

October 30, 2023

Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage; 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 67

iii. b.

ARTICLE IX OPEN RECORDS Section 9.1

Policy

The purpose for this policy is to set forth a general procedure to provide prompt and equitable service to those requesting access to public records and to establish reasonable and consistent fees for providing documents and so that the District can recover a portion of the cost of staff time for responding to open records requests.

In accordance with the Colorado Open Records Act, §24-72-201, et seq., C.R.S. (CORA) the District shall make all public records as defined under CORA available for public inspection at reasonable times.

Subject to the limitations imposed by the CORA and as more fully identified in Section 12.4 below, public records are all documents that exist on a piece of paper; this also includes recorded media and electronic mail communications (emails).

Recording of executive sessions shall be retained as required by law. The custodian shall have those recordings destroyed after the prescribed retention period has expired.

Section 9.2

Procedures

The General Manager is the official custodian of all records that are maintained by the Districts.

Citizens may make informal requests to the District employees for copies of specific identifiable public records as defined by CORA that are readily available in the custody and control of various employees. Generally, the employee will make reasonable efforts to fill requests for those records as soon as reasonably practical.

Any request that cannot be filled immediately or for which there is disagreement as to whether the document is a public record shall be made in writing to the General Manager who will, in consultation with the District’s attorney, review the records request to determine the status of the documents prior to their release.

If the written request cannot be filled immediately or the records are otherwise not readily available at the time the request is made, the General Manager will set a date and time for records inspection that is within three working days of the date on which the request was made. Such period may be extended if extenuating circumstances exist (per §24-72203(3)(b), C.R.S.), but the total time including the extension period will not exceed seven working days from the date on which the request is made.

The Districts may respond to written requests for access to public records stored electronically and in computer databases by providing a paper copy, disk, printout or by allowing access to a computer. Before releasing any electronic data, the General Manager will determine that the electronic data are not subject to the deliberative process privilege or work product privilege. October 30, 2023 72

Requests by the media shall be made directly to the Community Relations Manager. The Community Relations Manager will make every reasonable effort to comply with the media request. If the Community Relations Manager is unable to fill the request, the Community Relations Manager will direct the media to submit a written request to the General Manager. Thereafter, the request will be governed by the provisions of this policy and CORA.

Section 9.3

Charges

There shall be a charge for any copies, printouts, or photographs requested. The cost for a standard size photocopy will be $0.25 per copy.

There is no charge for the first hour of staff time used for a) the organization of data, b) research to locate and gather requested documents, and/or c) to otherwise manipulate the documents to make them appropriate for release, for instance, to redact documents to excise privileged material. For subsequent time required the standard charge for a District employee to perform this research shall be the maximum allowed by state law ($30.00 per hour as of the adoption of this policy). A time-log will be kept for any time in excess of one hour. Prior to beginning the project, the General Manager shall inform the person requesting the records of the hourly fee for the second and subsequent hours to perform the work and an estimate of the number of hours which will be required. Upon payment of the amount estimated, the District shall begin processing the request. Persons making a subsequent request for the same record shall be charged the same fee.

The fee charged for access to public records in electronic form will be based on recovery of the actual incremental costs associated with building and maintaining the database, as determined by the Information Technology division.

Unless it requires extensive staff time, the District does not charge for requests from: 1.

other Colorado governmental entities;
