In 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.
