CMS repaired and recoated a 100,479-BBL JP-8 cut-and-cover jet fuel tank on Guam. We performed repairs to the tank pits, hatch and cover, vent outlet covers, and various valves and piping. We also erected scaffolding for containment around the tank vent and manway and then blasted and removed the existing tank coating containing lead-based paint (LBP) and hexavalent chromium [CR(VI)].

New work involved providing fuel-compatible sealants at various interior penetrations, installing stilling wells of various heights, and replacing the exterior handrail system for the steps leading up to the tank. After all mechanical repairs, new coatings were applied to the roof, interior shell, floor, manways, and associated appurtenances.
