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. Is the hatch raised at least 24” above the roof or is on below tanks or or 4“ above the roof for above tanks level or Hatch on Finished Water Storage Tank is not elevated to the required height. (see photo #) Above Ground (elevated or ground-level, where the hatch is greater than 4 feet above ground level): The tank hatch must be framed at least four inches above the surface of the roof. Ground (buried or partially buried): The tank hatch must be elevated a minimum of 24 inches above the top of the tank surface or ground surface, whichever is higher. Does the hatch have a shoe box lid? Hatch on Finished Water Storage Tank does not have a shoe box lid. (see photo #) The tank hatch must be fitted with a solid watertight cover which extends around the frame at least two inches. Is the lid tight and sealed with a rubber on Finished Water Storage Tank does not have a gasket that creates a water tight seal. (see photo #) The tank hatch must have a rubber gasket to seal the hatch lid to the frame tightly to prevent contamination (including contamination carried by insects, rodents, and birds) from entering the water system. Is the hatch on Finished Water Storage Tank does not have a locking device. (see photo #) The cover must have a locking device. Is the site to Storage tank located in an area subject to flooding. (see photo # [insert site specific problem and remedy] Does the tank Storage tank not structurally sound or properly maintained. (see photo # The storage tank does not appear to be structurally sound. Specifically, the [tank component] of the tank must be evaluated by a professional engineer familiar with the construction of water-storage tanks to determine the integrity of the tank’s [tank component]. to maintain the structural and sanitary integrity of the tank could lead directly to contamination within the tank, illness and/or the loss of property. The professional evaluation of the storage tank must be made as soon as possible and it must be repaired if necessary to ensure the structural integrity and reliability of the
