§ 52.050 PRETREATMENT.
   (A)   The Public Works Director may require an existing or new user to provide wastewater pretreatment systems or facilities when the Public Works Director 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 federal pretreatment standards, or to accomplish any pretreatment result required by the Public Works Director in order to effectuate the purposes of the chapter. Any pretreatment facilities required by the Public Works Director 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 Public Works Director. The requirement for such approval, however, shall not absolve the user of the responsibility for meeting any industrial wastewater discharge limitation imposed by the town 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 town, or are not operated in compliance with the discharge requirements and limitations imposed by the town, 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 Public Works Director, shall install and maintain approved combustible gas detection meter systems. All pretreatment systems determined by the Public Works Director 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 Public Works Director.
   (B)   The Public Works Director 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 Public Works Director 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 Public Works Director. Floor drains from existing or new service garages, repair shops, equipment shops and vehicular maintenance facilities are not allowed.
   (D)   The town shall annually publish in the largest daily town 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.
