About this file

This document is an architectural engineering drawing for an Underground Storage Tank (UST) facility located at 840 West Hollis Street in Nashua, New Hampshire, with the facility number 8403099. The drawing is sheet 3 of 3, dated 8/11/25, and includes detailed technical specifications for Tank No. 9, which is an On Road Diesel storage tank with a safe fill height of 6'-8". The drawing provides three specific technical details: an AST Marking Detail with NFPA symbols for fuel types, a Positive Limiting Barrier Detail for the concrete pad, and a Control Joint Detail for concrete installation.

The technical drawing includes precise specifications for tank marking, using 2" high black letters on a white background, and a diamond-shaped NFPA symbol system with color-coded backgrounds indicating different fuel types (diesel, fuel oil, kerosene). The Positive Limiting Barrier Detail shows a reinforced concrete pad with specific dimensional requirements, while the Control Joint Detail specifies a 1/4" wide, 2" deep joint filled with self-leveling joint sealant. These technical specifications appear to be part of a comprehensive underground storage tank installation or renovation project, focusing on safety, proper marking, and structural integrity of the fuel storage infrastructure.
