(A) The control authority may require an existing or new user to provide wastewater pretreatment systems or facilities when the control authority determines that it is necessary to treat industrial flows prior to discharge to the sewer, to restrict or prevent the discharge to the sewer of certain waste constituents, to distribute any peak discharges of industrial wastewaters more equally over a longer time period, to comply with any state discharge or pretreatment requirements, to comply with pretreatment standards, or to accomplish any pretreatment result required by the control authority in order to effectuate the purposes of this chapter. Any pretreatment facilities required by the control authority shall be provided and maintained at the expense of the user. Pretreatment systems or facilities shall not be installed or operated without the prior written approval of the control authority. The requirement for such approval, however, shall not absolve the user of the responsibility for meeting any industrial wastewater discharge limitation imposed by the City or by the state or federal government if inspections or other information reveal that pretreatment systems and facilities are not installed or operated in conformance with the plans and procedures submitted to and approved by the City, or are not operated in compliance with the discharge requirements and limitations imposed by the City, the user shall make such modifications as are necessary to meet such requirements. Users who have the potential to discharge significant levels of flammable substances, as defined by the control authority, shall install and maintain approved combustible gas detection meter systems. All pretreatment systems determined by the control authority to require engineering design shall have plans prepared and signed by a civil, chemical, or mechanical engineer registered in the state or a registered engineer of other suitable discipline as determined by the control authority.
(B) The control authority may require any user discharging into the POTW to install and maintain, on their property and at their expense, a suitable storage and flow control facility to ensure equalization of flow. A wastewater discharge permit may be issued solely for flow equalization.
(C) Gravity separation interceptors, equalizing tanks, neutralization chambers, control manholes or other monitoring facilities, and spill containment systems, may be required by the control authority as he or she deems necessary to remove prohibited settleable and floatable solids, to equalize wastewater streams varying greatly in quantity and/or quality, to neutralize low or high pH wastewater, to facilitate inspection, flow measurement, and sampling, and to prevent discharge to the sewer of quantities of prohibited or restricted materials resulting from a rupture of a tank or pipeline or other such accidental occurrences. Spill containment systems shall conform to guidelines established by the control authority. Floor drains from existing or new service garages, repair shops, equipment shops, and vehicular maintenance facilities are not allowed.
(D) The City shall annually publish in the largest daily City newspaper a list of users which were in significant noncompliance. The names of the industrial users and their violations will be published. The status of the noncompliance and the enforcement action will be noted.
