Class A permit holders are regulated, in accordance with the requirements specified in the pretreatment regulations, 40 CFR Part 403 and 40 CFR Chapter I, Subchapter N, Parts 405-471, as amended, and these rules and regulations.

B.    Class B Discharge Permit. A Class B permit shall be issued, at the discretion of the plant manager, any user who is not a significant industrial user, yet requires periodic inspection and/or monitoring to verify compliance with these rules and regulations. A Class B permit may be required for discharge of industrial waste from stationary sources, trucked wastes, contaminated groundwater and other industrial wastes approved by the plant manager for discharge to the sanitary sewer.

1.    Groundwater sources may include but are not limited to (a) construction site dewatering where soil or groundwater contamination is present, (b) groundwater contaminated with organic solvents generated as a result of pump tests in preparation for a groundwater cleanup or water generated during sampling events, (c) aqueous wastes generated by either permanent or mobile hazardous waste treatment units used to treat hazardous waste at the generator’s site, (d) and aqueous wastes generated as a result of site cleanup activities. A permit must be obtained prior to commencement of discharge, and request for such permits shall be submitted not less than thirty working days prior to intended discharge.

2.    The plant manager limits groundwater discharges to a cumulative total hydraulic allocation of one-half million gallons per day (mgd) for the protection of the hydraulic capacity of the sanitary sewer system and the POTW. Real properties of the city or district shall have priority to such allocation. Allocations for other permit holders may be reduced, but not eliminated, to equitably accommodate the needs of the agencies to discharge treated groundwater to the sanitary sewer. Should such a permit holder discontinue discharging for more than ninety days, the permit holder shall be notified in writing of the plant manager’s intention to cancel the permit.

E.    The plant manager may impose upon the user a hydraulic loading charge for discharge of groundwater or other waters in cases where conventional sewer service charges applied by the city or district do not account for such flows or uses. User discharges which exceed ten thousand gallons per batch discharge or users undertaking long term discharges of groundwater to the sanitary sewer shall be metered and levied a hydraulic loading charge based upon the basic sewer service charge rate established by the city or district, as applicable. (Ord. 126 § 1 (part), 2009)

8.37.270 Modification, suspension or revocation of permit.

A.    A wastewater discharge permit may be revoked, made subject to additional terms and conditions, modified or suspended by the plant manager in addition to other remedies provided by law, when such action is necessary in order to stop discharge or a threatened discharge which presents a hazard or a threat of hazard to the public health, safety or welfare, or the natural environment, or the sewerage system, or which violates these rules and regulations, or which action is intended to implement programs or policies required or requested of the city or district by appropriate state or federal regulatory agencies.

B.    A user notified of the plant manager’s intent to revoke, make subject to additional terms or conditions, modify, or suspend the user’s permit shall immediately comply with directives of the plant manager or cease and desist the discharge of all industrial waste or such portion of such wastes as will eliminate the wrongful discharge to the sewer system pending any hearing that the user may request as set forth in these rules and regulations.

The notice of the meeting shall be served by certified mail, return receipt requested, at least ten days prior to the hearing. Such notice may be served on any authorized representative of the user.

D.    Compliance Order. When the plant manager finds that a discharge of wastewater is taking place or threatening to take place in violation of any provision of these rules and regulations or a permit or order issued hereunder, the plant manager may require the user to submit for approval of the plant manager, with such modifications as the plant manager deems necessary, a detailed compliance schedule that the user shall take in order to correct the violation(s), or prevent future recurrences of such violation(s). A compliance order may not extend the deadline for compliance established for a pretreatment standard or requirement, nor does a compliance order relieve the user of liability for any violation, including any continuing violation.

E.    Cease and Desist Order. When the plant manager finds that a discharge of wastewater is taking place or threatening to take place in violation of these rules and regulations or any permit or order issued hereunder, or that the user’s past violations are likely to recur, the plant manager may issue an order to cease and desist and direct that the user in violation immediately comply with all requirements, and 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.

F.    Administrative Civil Penalties. The plant manager may serve an administrative complaint on any user who has violated, or continues to violate, any provision of these rules and regulations or permits and orders issued hereunder, or any other pretreatment standard or requirement. Each day on which each instance of noncompliance shall occur or continue shall be deemed a separate and distinct violation. Procedures for application of administrative civil penalties shall be in accordance with standard procedures adopted by the city or district.

G.    Emergency Termination of Service. The city or district reserves the right to terminate sewer service for noncompliance with the provisions of these rules and regulations which reasonably appear to present an imminent endangerment to health, safety and welfare of persons. The user shall immediately cease discharge of any waste presenting such a hazard, upon verbal and/or written notice of the plant manager or his (her) designated representative. Such termination shall be effective immediately, but shall be reviewable pursuant to the hearing process provided by the city or district. The plant manager shall allow the user to recommence its discharge when the user has demonstrated to the satisfaction of the plant manager that the period of endangerment has passed, and provisions have been made to prevent future occurrences of actual or threatened discharges which may result in endangerment to individuals, the environment, damage to facilities or NPDES permit violations. (Ord. 126 § 1 (part), 2009)

8.37.460 Judicial enforcement remedies.

A.    Injunctive Relief. When the plant manager finds that a user has violated, or continues to violate, any provision of these rules and regulations, a wastewater discharge permit or order issued hereunder, or any other pretreatment standard or requirement, the plant manager may, through the attorney of the city or district, petition the superior court for the county of San Mateo for the issuance of a temporary or permanent injunction, as appropriate, which restrains or compels the specific performance of the wastewater discharge permit, order, or other requirement imposed by these rules and regulations on activities of the user. The plant manager may also seek such other action as is appropriate for legal and/or equitable relief. A petition for injunctive relief shall not be a bar against, or a prerequisite for, taking any other action against the user. In addition to the penalties provided herein, any condition caused or permitted to exist in violation of a provision of this code is a public nuisance and may be summarily abated as such. Each day that the condition continues it is a new and separate offense. Pursuant to Section 38773.5 of the California Government Code, in any action, administrative proceeding, or special proceeding brought by the district to abate a public nuisance, the prevailing party shall be entitled to reasonable attorneys’ fees. Recovery of attorneys’ fees shall be limited as follows:

1.    To those actions or proceedings where the district has elected to recover attorneys’ fees at the initiation of such actions or proceedings.

2.    The amount of attorneys’ fees in any action, administrative action, or special proceeding awarded to a prevailing party shall not exceed the amount of reasonable attorneys’ fees incurred by the district in the action or proceeding.

B.    Civil Penalties. A user who intentionally or negligently violates any provision of these rules and regulations, or any discharge permit or order issued hereunder, shall be liable for a civil penalty of not more than ten thousand dollars plus actual damages incurred by the city or district for as long as the violation continues. In addition to the above-described penalty and damages, the agency may recover reasonable attorneys’ fees, court costs and other expenses associated with the enforcement activities, including sampling and monitoring expenses. The agency shall petition the court to impose, assess and recover such sums. In determining amount of 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, any economic benefit gained through the violation, corrective actions by the violator, the compliance history of the violator, and any other factor as justice requires.

C.    Criminal Penalties. A user who intentionally or negligently makes any false statements, representations or certifications in any application, record, report, plan or other document filed or required to be maintained pursuant to these rules and regulations, or wastewater discharge permit, or who falsifies, tampers with, or knowingly renders inaccurate any monitoring device or method required under these rules and regulations, or who wilfully or negligently introduces any substance into the sanitary sewer system which causes personal injury or property damage shall, upon conviction, be guilty of a misdemeanor, punishable by such criminal penalties as may be prescribed by the city or district. Any penalty shall be in addition to any other cause of action for personal injury or property damage available under state law. (Ord. 126 § 1 (part), 2009)

8.37.470 Affirmative defenses.

A.    Upsets. For the purposes of this section, “upset” means an exceptional incident in which there is unintentional and temporary noncompliance with categorical pretreatment standards because of factors beyond the reasonable control of the user. An upset does not include the result of operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation.

1.    An upset shall constitute an affirmative defense to an action brought for noncompliance with categorical pretreatment standards if the user demonstrates, through properly signed, contemporaneous operating logs, or other relevant evidence that an upset occurred and the user can identify the cause(s) of the upset; the facility at the time was being operated in a prudent and professional manner and in compliance with applicable operation and maintenance procedures; and the user informs the plant manager thereof within twenty-four hours of becoming aware of the upset. Where such information is given orally, a written report thereof shall be filed by the user within five days. The report shall contain a description of the upset, its cause(s), and impact on the user’s compliance status; the duration of noncompliance, including exact dates and times of noncompliance; and if the noncompliance is continuing, the time by which compliance is reasonably expected to be restored, and all steps taken or planned to reduce, eliminate, and prevent recurrence of such an upset.

2.    In any enforcement proceeding, the user seeking to establish the occurrence of an upset shall have the burden of proof. Users will have the opportunity for a judicial determination on any claim of upset only in the enforcement action brought for noncompliance with categorical pretreatment standards. Users shall control production of all discharges to the extent necessary to maintain compliance with categorical pretreatment standards upon reduction, loss or failure of its treatment facilities until the facility is restored or an alternative method of treatment is provided. This requirement applies in the situation where, among other things, the primary source of power of the treatment facility is reduced, lost or fails.

B.    Prohibited Discharge Standards. A user shall have an affirmative defense to an enforcement action brought against it for noncompliance with the prohibited discharge standards listed in these rules and regulations, with certain exceptions specified below if it can prove that it did not know, or have reason to know, that its discharge, alone or in conjunction with discharges from other sources, would cause pass-through or interference and that either:

1.    A local limit exists for each pollutant discharged and the user was in compliance with each limit directly prior to, and during, the pass-through and interference; or

2.    No local limit exists, but the discharge did not change substantially in nature or constituents from the user’s discharge when the POTW was in compliance with its NPDES permit, and in the case of interference, was in compliance with applicable sludge use or disposal requirements.

In no case will an affirmative defense be granted for discharge of pollutants which create a fire or explosion hazard in the sewerage system; or wastewater with a pH of less than 5.0 or greater than 10.5 or which otherwise will cause corrosive structural damage to the sanitary sewer system; or discharge of trucked or hauled pollutants without authorization from the plant manager.

C.    Bypasses. For the purposes of this section, “bypass” shall mean the intentional diversion of waste streams from any portion of a user’s treatment facility. “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.

1.    A user may allow a bypass to occur which does not cause pretreatment standards or requirements to be violated, but only if it is for essential maintenance to ensure efficient operation of the treatment system.

2.    If a user knows in advance of the need for a bypass, it shall submit prior notice to the plant manager, at least ten days before the date of the bypass, if possible. A user shall submit oral notice to the plant manager of an unanticipated bypass that exceeds applicable pretreatment standards within twenty-four hours from the time it becomes aware of the bypass, followed by a written submission to the plant manager within five days of the time the user becomes aware of the bypass. The written submission shall contain a description of the bypass and its cause, the duration of the bypass, including exact dates and times, and, if the bypass has not been corrected, the anticipated time it is expected to continue; and steps taken or planned to reduce, eliminate, and prevent recurrence of the bypass. The plant manager may waive the written report on a case-by-case basis if the oral report has been received within twenty-four hours.

3.    A bypass of the treatment system is prohibited unless the bypass was unavoidable to prevent loss of life, personal injury or severe property damage; or there was no feasible alternative to the bypass, including 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 backup equipment should have been installed in the exercise of reasonable engineering judgement to prevent a bypass which occurred during normal periods of equipment downtime or preventive maintenance, and the user submitted notices as required under subsection (C)(2) of this section. The plant manager may approve an anticipated bypass, after considering its adverse effects, if the plant manager determines that it will meet the conditions listed in this subsection.
