The plan set, dated 8/11/25 and revised on 8/21/25 to address NHDES (New Hampshire Department of Environmental Services) comments, provides detailed site layout, property plan, and installation specifications for the AST system. The drawing includes a locus map, property plan, and AST plan with comprehensive notes detailing installation requirements, safety protocols, and system configuration.

The technical specifications outline precise requirements for the AST system, including emergency shutoff systems, security fencing, interstitial sensors, and specific guidelines for tank placement, perimeter markings, and fuel nozzle positioning. The plan emphasizes safety and environmental compliance, with detailed notes about installation procedures, contractor responsibilities, and regulatory adherence.
