Page 13 <br /> 3.2 Additional Pretreatment Measures <br /> ® A. The Batesville Utilities Commission when it deems it to be <br /> reasonably necessary to the efficient operation of the POTW, <br /> may require industrial users to restrict their discharge <br /> during peak flow periods, designate that certain wastewater <br /> be discharged only into specific sewers, relocate or <br /> consolidate points of discharge, separate sewage <br /> wastestreams from industrial wastestreams, and such other <br /> conditions as may be necessary to protect the POTW and <br /> determine the industrial user's compliance with the <br /> requirements of this ordinance. <br /> B. Grease, oil and sand interceptors shall be provided when, in <br /> the opinion of the Batesville Utilities Commission, they are <br /> necessary for the proper handling of wastewater containing <br /> excessive amounts of grease and oil, or sand; except that <br /> such interceptors shall not be required for residential <br /> users. All interception units shall be of type and capacity <br /> approved by the Batesville Utilities Commission and shall be <br /> so located to be easily accessible for cleaning and <br /> inspection. Such interceptors shall be inspected, cleaned, <br /> and repaired regularly, as needed, by the owner at their <br /> expense. <br /> C. Industrial users with the potential to discharge flammable <br /> substances may be required to install and maintain an <br /> approved combustible gas detection meter. <br /> 3 . 3 Accidental Discharge-Slug Control Plans <br /> The Batesville Utilities Commission may require any industrial <br /> user to develop and implement an accidental discharge-slug control <br /> plan. At least once every two years the Manager shall evaluate whether <br /> each significant industrial user needs such a plan. Any industrial <br /> user required to develop and implement an accidental discharge-control <br /> slug plan shall submit a plan which addresses, at a minimum, the <br /> following: <br /> A. Description of discharge practices, including nonroutine <br /> batch discharges. <br /> B. Description of stored chemicals . <br /> C. Procedures for immediately notifying the POTW of any <br /> accidental or slug discharge. Such notification must also <br /> be given for any discharge which would violate any of the <br /> prohibited discharges in Section 2 . 1 of this ordinance. <br /> D. Procedures to prevent adverse impact from any accidental or <br /> slug discharge. Such procedures include, but are not <br /> limited to, inspection and maintenance of storage areas, <br /> handling and transfer of materials, loading and unloading <br /> operations, control of plant site run-off, worker training, <br /> building of containment structures or equipment, measures <br /> for containing toxic organic pollutants, including solvents, <br /> or measures and equipment for emergency response. <br />
