2026 Ketchikan High School UST Removal and AST Installation

The Ketchikan Gateway Borough is seeking the services of a qualified general contractor to perform the removal of an existing 8,000-gallon Underground Storage Tank (UST) and installation of a new 10,000-gallon Aboveground Storage Tank (AST) serving Ketchikan High School, a 72,205-square foot sprinkled building of Type II Construction, 1-hour rated. Work will include all necessary demolition, environmental mitigation, contaminated soils disposal (where encountered), backfill, driveway road bed restoration, piping, signals, and coordination with building operations.

Ketchikan High School was thoroughly renovated from 1991-1995, during which project an older 20,000-gallon UST was taken out of service and a new 8,000-gallon UST installed immediately adjacent. This UST fuels the building's boiler systems located in the boiler room nearby, and is therefore a "tank used for storing heating oil for consumptive use on the premises where stored" pursuant to Alaska Statute (AS) 46.03.365(9)(B) and not required to be registered with the Alaska Department of Environmental Conservation.

A 2025 examination revealed that one of the two inspection port exhibited discharged fuel, after which ADEC Contaminated Sites Program opened File Number 1516.38.060 for Hazard ID 28125. This project seeks to close the hazard file through elimination and environmental remediation of the UST.
