This opportunity involves preventative maintenance for underground and aboveground storage tanks. The base year requires pricing for decommissioning two ASTs at building 20, while option years cover pricing for polishing one 40,000-gallon UST. Monthly UST inspections are also required across all contract periods. Contractors must include bullet points of deliverables and exemptions for work not performed. The location for AST decommissioning is building 20, but no budget amounts or submission timelines are specified.
