(C) Immediate Reporting. Immediately upon discharging a prohibited substance or upon discovering that a prohibited substance has been discharged, the person performing or discovering such discharge shall immediately notify the staff of the district of the discharge by the most rapid available means, if such person knows or reasonably should have known that (1) the substance was discharged, and (2) the discharge of the substance was prohibited. Notification pursuant to this subsection does not relieve the person notifying of any liability, except liability for violation of this subsection.
(D) Preventing Accidental Discharge.
(1) Generally. Every person conducting an activity which creates a substantial risk that a prohibited substance will be discharged into the sewer system shall provide adequate protection against accidental discharge of such a prohibited substance by either (a) implementing procedures or practices which tend to reduce the likelihood of such a discharge, and/or (b) installing facilities designed to prevent such accidental discharge. The district general manager may identify persons required to provide such protection and direct them to comply with this subsection.
(2) City/District Requirements. The City Public Works Director and/or the district general manager are hereby authorized to specify particular procedures, practices, and/or facilities which shall be implemented by any person, (a) if the district general manager finds that there is substantial risk of a discharge prohibited by this section if preventive measures are not undertaken, and (b) if such procedures, practices and/or facilities substantially reduce the risk of discharge prohibited by this section, and (c) if the cost of implementing such procedures, practices, and/or installing such facilities is found by the City Council and/or district board to be reasonable in light of both the potential damage to the sewer system and/or the environment if an accidental discharge occurs, and the effectiveness of the equipment in preventing such an accidental discharge.
(3) Plans. In every case where facilities are required to be installed pursuant to this subsection, the Public Works Director and/or district general manager are hereby authorized to require submission of detailed plans for the required facilities and their operation before construction of the facilities is begun.
(E) Preventive Requirements.
(1) Report. Within five days after the discharge of a prohibited substance, the person who discharged such substance shall file with the City a written report describing (a) the nature and content of the discharge, (b) the cause(s) of the discharge, and (c) remedial measures to be taken by the discharger to prevent similar discharges in the future. The City Public Works Director or his designee may inspect the site of the accidental discharge and interview any person involved in the discharge in order to ascertain or confirm what happened and assure that remedial measures adequate to prevent future accidents are carried out as represented.
(2) Authorization to Require Changes. If (a) a person has discharged a prohibited substance, and (b) it is likely that the same person will again discharge a similar prohibited substance in the future if preventive measures are not undertaken, then the Public Works Director is hereby authorized to require the person who discharged the prohibited substance to make change(s) in equipment, facilities, procedures, or practices, which change(s): (a) have the effect of substantially reducing the risk of a similar discharge in the future, and (b) are found by the Public Works Director to be reasonable in cost in light of the potential damage to the system and environment arising out of a similar prohibited discharge in the future. Nothing in this subsection relieves any person of any liability, except liability for violation of this subsection.
(F) Self-Monitoring and Reporting. The Public Works Director is hereby authorized to require that persons discharging into the sewer system, other than persons discharging only ordinary domestic sewage, monitor and report their sewage discharges in a manner and to the extent necessary to: (1) provide adequate compliance with and enforcement of the district’s wastewater control rules and regulations; (2) assess the source of the components of the sewage transmitted by the City and treated and disposed of by the district; and (3) charge reasonable fees and surcharges to dischargers based on actual discharges or reasonable classifications of discharges. The Public Works Director is further hereby authorized to require that such monitoring and reporting be performed at the expense of the person discharging. Every person required to monitor and report pursuant to this section shall monitor and report as required by the district wastewater control rules and regulations and in conformity with this section.
(G) Compliance Monitoring. The district pretreatment administrator is hereby authorized to sample and analyze the sewage of, and inspect the facilities of, persons discharging into the sewer system in order to determine or verify compliance with this section. The City Council is further authorized to require the installation of reasonable facilities, such as manholes, to enable such sampling. However, nothing in this section limits any power that the City or District may have to investigate or enforce compliance with other sections of this chapter or through means not specified in this subsection.
(H) Strict Liability. Any person violating any provision of this section shall be guilty without regard to fault, knowledge, intent, or the state of mind of the person committing the violation.
(I) Nuisance. Any condition or situation which causes a violation of this section is hereby declared to be a public nuisance and may be abated as provided by law. [Ord. 12-07 § 1 (Exh. A); Code 1971 § 4-02-100.]
