1. GENERAL: This Performance Work Statement (PWS) forms the requirements to remove water from within the interstitial space of the designated 5,500-gallon fuel tank in building 6 located at Koke’e Air Station.

This effort will mitigate risks such as corrosion, fuel degradation, and restore the tank to federal EPA compliance for fuel storage tanks. The work must be fully completed to restore safe and reliable operational conditions. The contractor shall identify and comply with all applicable federal, state, and local statutes.
