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 wastes, sand, or other harmful ingredients; except that such 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 cleaning and inspection.
   (A)   Grease interceptors shall be pumped and cleaned at a frequency sufficient to maintain compliance with the requirements of this chapter.  At a minimum a grease interceptor shall be cleaned and pumped whenever the combined thickness of the floating greases and settled solids is equal to or greater than 25% of the content of the interceptor.  If repairs are required, they shall be performed within seven days.
   (B)   When required by the Superintendent, grease interceptors shall be pumped and cleaned within 48 hours.  When in the opinion of the Superintendent the environment is threatened, the Superintendent may require a facility to immediately cease operations until the facility’s grease interceptor is cleaned and pumped.
   (C)   Grease interceptors shall have monitoring locations adequate for obtaining representative effluent samples.  Unless otherwise stated in an industrial wastewater discharge permit, the local limits set forth in §§ 52.027, 52.028 and 52.067 shall apply at these monitoring locations.
   (D)   Users shall document all cleaning and maintenance activities performed on their grease interceptors.  Copies of grease hauling and handling manifests shall be maintained on site.  These records shall be maintained for a minimum of three years and be available for inspection and copying by the Superintendent or designee.
