About this file
This technical drawing is a detailed engineering blueprint for an Aboveground Storage Tank (AST) System located at 840 West Hollis Street in Nashua, New Hampshire, with the facility number 8403099. The document is sheet 2 of 3, dated 8/11/25, and includes comprehensive system details such as a tank layout, dispenser configuration, overfill prevention valve float detail, bollard detail, and emergency shut-off mechanisms. The drawing provides precise technical specifications for tank infrastructure, including reinforced concrete foundations, steel piping, valves, sensors, and installation requirements.
The technical drawing includes specific components like a block valve (Morrison), check valve, high-level alarm, emergency relief pipes, and detailed mounting and positioning instructions for various system elements. The design appears to be compliant with regulatory standards, as evidenced by the notation of "NHDES COMMENTS" in the revision log, suggesting New Hampshire Department of Environmental Services review and potential modifications. The drawing provides technical guidance for the installation and configuration of a complex storage tank system with multiple safety and operational features.
