EPA will review the inspection report and may require additional corrective actions. Does the drain pipe have an air gap of 3 or more pipe the to any or Drain on finished water storage tank is directly connected to a sanitary sewer, combined sewer or storm sewer drain*. (see photo #) No drain may be directly connected to a sanitary sewer, combined sewer or storm sewer drain. An air gap must be present such that the drain pipe terminates at least three pipe diameters above the ground level at the sewer drain, storm drain, splash pad or engineered rip-rap. Does the tank have a vent from the No vent on finished storage tank. In order to protect the structural integrity of the tank during changes to tank water levels, and other events affecting the confined air space, the tank must have a vent that is separate from the overflow.
