In order to correct this significant deficiency you must provide EPA with the following documentation: A completed copy of the Unknown Integrity Checklist. A copy of the inspection report. The inspection report must describe the condition of each specified tank component and include photographs. The date that any corrective actions needed to address deficiencies with the tank components will be completed. EPA will review the inspection report and may require additional corrective actions. Does the pipe have an air gap of 3 or more pipe above the to any storm or Drain on finished water storage tank is directly connected to a sanitary sewer, combined sewer or storm sewer drain. (see photo #) No 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 Does the tank have a vent from the No vent on finished water storage tank. In 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. Is the vent for Unknown integrity of storage tank air vent [add other inaccessible components to consolidate language]. The sanitary surveyor was unable to evaluate the tank air vent [add components to consolidate], and the water system was not able to produce documentation of the condition of these components. Each item that could not be inspected during the sanitary survey must be inspected and the must be compared to the enclosed Tech Tips for Finished Water Storage Facilities to determine if corrective action is needed. Tank inspectors can be third-party professionals or appropriately trained in-house staff.
