§ 54.051  ADDITIONAL PRETREATMENT MEASURES.
   (A)   Whenever deemed necessary, the Superintendent may require users to restrict their discharge during peak flow periods, designate that certain wastewater be discharged only into specific sewers, relocate and/or consolidate points of discharge, separate sewage wastestreams from industrial wastestreams, and such other conditions as may be necessary to protect the POTW and determine the user’s compliance with the requirements of this chapter.
   (B)   The Superintendent may require any person discharging into the POTW to install and maintain, on his or her property and at his or her 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)   Users with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas detection meter.
   (D)   Grease, oil and sand interceptors shall be provided when, in the opinion of the Superintendent, they are necessary for the proper handling of liquid wastes containing grease in excessive amounts, or any flammable waste, sand or other harmful ingredients; except that, these interceptors shall not be required for private living quarters or dwelling units. All interceptors shall be of a type and capacity approved by the Superintendent, and shall be located as to be readily and easily accessible for inspection, and kept clean at all times. Grease and oil interceptors shall be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperature. They shall be of substantial construction, water-tight, and equipped with easily removable covers which when bolted in place, shall be gas-tight and water-tight, and capable of the maximum flow rate of the pipe installed therein.
