14.12.345 - Limitation on wastewater strength.

No person shall discharge industrial wastewater to the POTW unless the wastewater conforms to this chapter. Discharge limitations shall be revised and adopted by resolution of the City Council as necessary to ensure the POTW's compliance with the NPDES permit. For Categorical industrial users, a BMR must be conducted as per requirements of the 40 CFR 403.12(b). For categorical industrial users, the City may exercise one or more of the following options:

A. Where a categorical pretreatment standard is expressed in terms of either the mass or the concentration of a pollutant in wastewater, the Director may impose equivalent concentration or mass limits in accordance with 40 CFR 403.6(c);

B. When wastewater subject to a categorical pretreatment standard is mixed with wastewater not regulated by the same standard, the Director shall impose an alternate limit using the combined wastestream formula; and

C. A variance from a categorical pretreatment standard may be issued if the user can prove, pursuant to the procedural and substantive provisions in 40 CFR 403.13, that factors relating to its discharge are fundamentally different from the factors considered by the EPA when developing the categorical pretreatment standard.

(Ord. 7362 §6, 2017; Ord. 7032 §2, 2009; Ord. 6637 §2 (part), 2002; Ord. 6232 §2 (part), 1995)

Exceptions & meaning →

14.12.350 - Local limits.

A. The Director shall develop and implement specific prohibitions, pollutant limitations, pollutant parameters and best management practices (BMPs) ("local limits"). These local limits are necessary to assure compliance with the City's NPDES permit, including preventing pass through, interference, or impacts to biosolids reclamation or reuse. These local limits may be continually developed as necessary and adopted by resolution after public notice to affected persons or users.

B. The local limits may be allocated among industrial user classes or individual users as uniform concentration limits, or as the ratio of the total mass per user, or as a selected industry reduction, or by such other method considering factors such as persistence of the pollutant, equity, treatment feasibility, economic feasibility, and economics of scale, pollution prevention and waste minimization measures, anticipated growth and enforcement feasibility.

C. User-specific allocations at current loadings may be created for public health facilities which provide a lifesaving service or procedure, so long as the pollutant discharged would not contribute to pass-through, interference or other violation of the City's NPDES permit.

D. Pollutant allocations may be granted to Class III or Class V users on a case-by-case basis based upon the POTW's excess treatment capacity for the pollutant requested. These limits shall be based upon the pounds of pollutant(s) discharged and the impacts on the treatment capabilities of the POTW. If the permit is issued for more than one year, a pollutant review will take place annually to determine the POTW's excess treatment capacity for those permitted pollutants. A review may be conducted at any time if the Director finds that the Permittee's wastewater discharge has adversely affected the POTW, has caused a rise in that pollutant of more than 20 percent, or has caused interference, pass through, or violations of the POTW's NPDES permit.

E. When categorical pretreatment standards are expressed only in terms of pollutant concentrations, a categorical industrial user may request that the City convert the concentration limits to an equivalent mass limits. To be eligible for equivalent mass limits, the categorical industrial user must comply with the requirements in 40 CFR Part 403.6(c)(5)(i-iv).

F. The director reserves the right to establish, by ordinance or in individual wastewater discharge permits, more stringent standards or requirements on discharges to the POTW consistent with the purpose of this ordinance.

G. Local limits adopted by resolution of the City Council are pollutant limits for discharges to the POTW established to protect against pass through and interference. No person shall discharge wastewater containing pollutants in excess of the local limits adopted by City Resolution.

(Ord. 7551 §24, 2021; Ord. 7362 §6, 2017; Ord. 7032 §2, 2009; Ord. 6637 §2 (part), 2002; Ord. 6232 §2 (part), 1995)

Exceptions & meaning →

14.12.355 - De Minimis categorization.

Any user whose industrial wastewater discharge is less than 100 gallons per day and is not regulated by a federal categorical pretreatment standard or industrial user group permit may be classified in the Director's discretion as a De Minimis user and shall not be subject to permitting standards or local limits provided that such industrial wastewater discharge is not a hazardous substance, does not contribute to interference or pass through violations at the POTW or violations of the NPDES permit, and does not cause detrimental effects or damage to the POTW, or cause a threat of harm to City personnel, the public, or the environment. De Minimis user status shall terminate upon violation of this section, or upon written notice to such discharger of Director's determination that such discharger no longer satisfies the criteria of this section. Industries that discharge greater than 100 gallons per day may qualify under a Wastewater Discharge Authorization Certificate (WDAC).

O. All industrial and commercial facilities must comply with all the requirements contained within this chapter and must correct deficiencies noted during inspections or on any enforcement or compliance documents.

P. Stormwater may enter the sewer collection system with Director approval, and in accordance with the following:

  1. Users having outdoor areas which allow wastewater and storm water to enter the sanitary collection system, or for which the initial diversion of contaminated storm water would assist in the preservation of surface or subsurface water quality, may be required to install and maintain, at the user's expense, a storm water diversion system to mitigate the release of rainwater to the sanitary sewer during a storm event.

  2. The storm water diversion system design and use shall be reviewed and approved by the Director prior to installation, and must comply with rainwater diversion system design requirements.

  3. The system shall be designed to allow wastewater to enter the collection system during dry weather and divert excess storm water after the first 0.1 inches of rainfall back to the MS4 during storm events.

  4. During storm events, the user shall immediately suspend all outdoor wastewater generating activities and divert all storm water to a storm drain or impound contaminated water for release to the sanitary sewer after the cessation of rainfall.

  5. If the segregation of industrial wastewater and stormwater is infeasible, or if discharge of contaminated storm water would create a pollution threat to surface or subsurface waters, the user may make application to the Director requesting that the storm water be considered an industrial wastewater and approved for discharge to the POTW. Approval of a storm water discharge to the POTW shall be based on:

a. Hydraulic capacity of the collection system;

b. Hydraulic capacity of the treatment plant;

c. A demonstrated need to discharge storm water to the POTW to prevent surface and subsurface water contamination

d. Dry weather urban runoff diversions must also comply with the City's guidelines on dry weather diversion BMPs.

Q. All users must comply with this Chapter and must comply with the State Water Resources Control Board's storm water requirements. The Director may require storm water protection BMPs (such as covers over hazardous waste and chemical storage areas, cleaning of exposed areas prior to an expected rain event, etc.) to mitigate the potential release of pollutants to the storm drain, and cannot have equipment outside if it causes pollutants to have potential to enter storm water.

A slug discharge is any discharge of a non-routine, episodic nature, including, but not limited to, an accidental spill or a non-customary batch discharge, which has reasonable potential to cause interference or pass through, or in any other way violate the POTW's regulations, local limits and/or permit conditions, or any pollutant discharge violating the specific prohibitions under 40 CFR 403.5 (b). These specific prohibitions include at a minimum the following list of pollutants:

  1. Pollutants which create a fire or explosion hazard in the POTW, or having a Flash Point below 140 degrees Celsius;

  2. Pollutants which will cause corrosive structural damage to the POTW, or having a pH less than 5 or greater than 11.5;

  3. Solid or viscous pollutants which will cause obstruction in the POTW;

  4. Any pollutant, including oxygen demanding pollutants (COD, BOD, etc.) Released in a discharge at a flow rate and/or pollutant concentration which will cause interference with the POTW;

  5. Concentrated, off-spec, or spent products, reagents, or wastes;

  6. Heat in amounts which will inhibit biological activity in the POTW resulting in interference, but in no case heat in such quantities that the temperature at the POTW exceeds 40°C (104°F);

  7. Petroleum oil, non-biodegradable cutting oil, or products of mineral oil origin in amounts that will cause interference or pass through at the POTW;

  8. Pollutants which result in the presence of toxic gases, vapors, or fumes within the POTW in a quantity that may cause acute worker health and safety problems; and/or,

  9. Any trucked or hauled pollutants, except at discharge points designated by the POTW.

C. The Slug Discharge Prevention and Control Plan is intended to assist the permittee in evaluating their current practice in prevention and control of slug discharges. The Slug Discharge Prevention and Control Plan shall contain, at a minimum, the following elements:

  1. Description of discharge practices, including non-routine batch discharges;

  2. Description of stored chemicals, spill kits locations, and spill containment devices;

  3. Procedures for immediately notifying the Director of slug discharges, including any discharge which would violate a prohibition under 40 CFR Part 403, with procedures for follow-up written notification within five days;

  4. If necessary, procedures to prevent adverse impact from accidental spills, including inspection and maintenance of storage areas, handling and transfer of materials, loading and unloading operations, control of plant site runoff, worker training, building of containment structures or equipment, measurements for containing toxic organic pollutants (including solvents) and/or measures and equipment for emergency response.

D. Upon occurrence of an accidental discharge of substances prohibited by this Chapter, the permittee shall take mitigative actions to protect public safety and prevent release of restricted materials to the environment, and shall notify the City immediately. During normal business hours, the City shall be notified by telephone at (951) 351-6145. After 5:00 p.m. on Monday through Friday, or weekends and holidays, the City shall be notified by telephone at (951) 826-5311. The notification shall include the location of the discharge, date and time thereof, type of waste, including concentration and volume, and the corrective actions taken. The permittee's notification of the accidental release in accordance with this section does not relieve the Permittee from the reporting requirements of local, State, or Federal laws.

E. Within five days following an accidental discharge, the permittee shall submit to the City, a detailed, written report. The report shall specify the following:

  1. Description and cause of the upset, slug or accidental discharge, and the impact on the Permittee's compliance status. The description shall also include the location of the discharge, type, concentration and volume of waste.

  2. Duration of noncompliance including exact dates and times of noncompliance, and if noncompliance continues, the time by which compliance is reasonably expected to occur.

  3. All steps taken or to be taken to reduce, eliminate, and prevent recurrence of such an upset, slug, accidental discharge, or other conditions of noncompliance.

14.12.410 - Categorical pretreatment standards.

A. The federal categorical pretreatment standards found in 40 CFR Chapter I, Subchapter N are hereby incorporated into this chapter by reference. It is unlawful for any Categorical Industrial User to discharge wastewater to the POTW in violation of federal categorical pretreatment standards or any limitation in this chapter or that user's permit. Where there is more than one limitation for a pollutant, the more stringent limitation shall prevail. Compliance with federal categorical pretreatment standards for existing sources subject to such standards or for existing sources, which hereafter become subject to such standards, shall be achieved within three years following promulgation of the standards unless a shorter compliance time is specified in the standards or by the Director. New sources shall install, have in operating condition and "start-up" all pretreatment equipment to ensure compliance before beginning any discharge. New sources must meet all applicable pretreatment standards within the shortest feasible time, not to exceed 90 days.

B. The City may authorize a categorical industrial user to forego sampling of a pollutant regulated by a federal categorical pretreatment standard if the industrial user has demonstrated through sampling and other technical factors that the pollutant is neither present nor expected to be present in the wastewater discharge, or is present only at background levels from intake water and without any increase in the pollutant due to activities of the industrial user. This authorization is subject to the following conditions:

  1. The City may authorize a waiver where a pollutant is determined to be present solely due to sanitary wastewater discharged from the facility provided that the sanitary wastewater is not regulated by an applicable categorical standard and otherwise includes no process wastewater.

  2. The monitoring waiver is valid only for the duration of the effective period of the industrial user's permit, and in no case shall exceed five years. The industrial user must submit a new request for the waiver with each permit renewal.

  3. In making a determination that a pollutant is not present, the industrial user must provide data from a least one sampling of the facility's process wastewater prior to any treatment at the facility that is representative of all wastewater from all processes.

  4. The request for a monitoring waiver must be signed by the industrial user's authorized representative and include the certification statement as defined in Section 14.12.120.

  5. Non-detectable sample results may only be used as a demonstration that a pollutant is not present if the EPA approved method from 40 CFR Part 136 with the lowest minimum detection level for that pollutant was used in the analysis.

  6. Any grant of the monitoring waiver by the City will be incorporated into the industrial user's permit. All data and information to support the City granting the waiver will be maintained for three years after the expiration of the waiver.

  7. Upon approval of the waiver and incorporation into the Industrial User's Permit, the Industrial User must certify on each report submitted with the following statement, that there has been no increase in the pollutant in its wastestream due to the activities at the Industrial User's facility:

"Based on my inquiry of the person or persons directly responsible for managing compliance with the Pretreatment Standard for 40 CFR [specify applicable National Pretreatment Standard part(s)], I certify that, to the best of my knowledge and belief, there has been no increase in the level of [list pollutant(s)] in the wastestream due to the activities at the facility since filing the last quarterly report."

  1. In the event that a waived pollutant is found to be present or is expected to be present based on changes that occur in the industrial user's operations, the industrial user must immediately notify the City and resume quarterly monitoring of the waived pollutant.

  2. This waiver provision does not supersede certification processes and requirements established in categorical pretreatment standards, except as otherwise specified in the categorical pretreatment standard.

C. Users must comply with the categorical pretreatment standards found at 40 CFR Chapter I, Subchapter N, Parts 405-471.

14.12.447 - Baseline monitoring reports.

Reporting requirements for industrial users upon effective date of categorical pretreatment standard baseline report. Within 180 days after the effective date of a categorical Pretreatment Standard, or 180 days after the final administrative decision made upon a category determination submission under Federal Code 40 CFR 403.6(a)(4), whichever is later, existing Industrial Users subject to such categorical Pretreatment Standards and currently discharging to or scheduled to discharge to a POTW shall be required to submit to the Control Authority a report which contains the information as described below. At least 90 days prior to commencement of discharge, New Sources, and sources that become Industrial Users subsequent to the promulgation of an applicable categorical Standard, shall be required to submit to the City of Riverside a report which contains the information required. New sources shall also be required to include in this report information on the method of pretreatment the source intends to use to meet applicable pretreatment standards. New Sources shall give estimates of the information as requested:

  1. Identifying information. The user shall submit the name and address of the facility including the name of the operator and owners;

  2. Permits. The user shall submit a list of any environmental control permits held by or for the facility;

  3. Description of operations. The user shall submit a brief description of the nature, average rate of production, and standard industrial classification of the operation(s) carried out by such industrial user. This description should include a schematic process diagram which indicates points of discharge to the POTW from the regulated processes.

  4. Flow measurement. The user shall submit information showing the measured average daily and maximum daily flow, in gallons per day, to the POTW from each of the following:

(i) Regulated process streams; and

(ii) Other streams as necessary to allow use of the combined wastestream formula of 40 CFR 403.6(e).

The City of Riverside may allow for verifiable estimates of these flows where considerations are justified by cost or feasibility.

  1. Measurement of pollutants.

(i) The user shall identify the pretreatment standards applicable to each regulated process;

(ii) In addition, the user shall submit the results of sampling and analysis identifying the nature and concentration (or mass, where required by the City of Riverside) of regulated pollutants in the discharge from each regulated process. Both daily maximum and average concentration (or mass, where required) shall be reported. The sample shall be representative of daily operations. In cases where the standard requires compliance with a best management practice or pollution prevention alternative, the user shall submit documentation as required by the City of Riverside or the applicable standards to determine compliance with the standard;

(iii) For sampling required in support of baseline monitoring and 90-day compliance reports required, a minimum of four grab samples must be used for pH, cyanide, total phenols, oil and grease, sulfide and volatile organic compounds for facilities for which historical sampling data do not exist; for facilities for which historical sampling data are available, the Director may authorize a lower minimum. For the reports required under (40 CFR 403.12(e) and 403.12(h)), the industrial user is required to collect the number of grab samples necessary to assess and assure compliance with applicable pretreatment standards and requirements.

(iv) Samples should be taken immediately downstream from pretreatment facilities if such exist or immediately downstream from the regulated process if no pretreatment exists. If other wastewaters are mixed with the regulated wastewater prior to pretreatment the user shall measure the flows and concentrations necessary to allow use of the combined wastestream formula in order to evaluate compliance with the applicable pretreatment standards. Where an alternate concentration or mass limit has been calculated, this adjusted limit along with supporting data shall be submitted to the City of Riverside;

(v) Sampling and analysis shall be performed in accordance with the techniques prescribed in 40 CFR part 136 and amendments thereto. Where 40 CFR part 136 does not contain sampling or analytical techniques for the pollutant in question, or where the Director determines that the part 136 sampling and analytical techniques are inappropriate for the pollutant in question, sampling and analysis shall be performed by using validated analytical methods or any other applicable sampling and analytical procedures, including procedures suggested by the POTW or other parties, and approved by the Director;

(vi) The City may allow the submission of a baseline report which utilizes only historical data so long as the data provides information sufficient to determine the need for industrial pretreatment measures;

(vii) The baseline report shall indicate the time, date and place, of sampling, and methods of analysis, and shall certify that such sampling and analysis is representative of normal work cycles and expected pollutant discharges to the POTW;

  1. Certification. A statement, reviewed by an authorized representative of the industrial user and certified to by a qualified professional, indicating whether pretreatment standards are being met on a consistent basis, and, if not, whether additional operation and maintenance (O and M) and/or additional pretreatment is required for the industrial user to meet the pretreatment standards and requirements; and

  2. Compliance schedule. If additional pretreatment and/or O and M will be required to meet the pretreatment standards; the shortest schedule by which the industrial user will provide such additional pretreatment and/or O and M.
