Attachment G - Return To Service Letter.pdf

This is a Return to Service Letter template documenting the completion of an out-of-service API 653 storage tank inspection for a fuel system. The letter confirms that a specified storage tank has been inspected for serviceability evaluation in accordance with API STD 653 requirements and is suitable for return to service, with no mandatory repairs required to prevent imminent risk to system operators, equipment integrity, or the adjacent environment. The inspection was performed by a company on a specified date, and the tank was returned to service on the documented date.

The letter includes recommended future inspection dates, including the next API 653 out-of-service tank inspection and in-service tank inspection, along with other specialized inspections such as ultrasonic roundness and corrosion testing. It references applicable state regulations for API 653 out-of-service tank inspections and specifies inspection frequency requirements. The document requires signature and certification from an API 653 Certified Inspector, acknowledgment from the Installation Point of Contact, and authorization from the USACE Fuels Project Manager. Final documents are to be included in close-out documentation as required by the associated task order. The letter is associated with a specific contract number and task order for fuel system inspection work at a designated location.
