Exhibit A is a technical specification document for a Fiberglass Reinforced Polymer (FRP) storage tank required by the City of Fort Worth Water Department as part of an RFP for chemical tank procurement on an as-needed basis. The specification details a single vertical filament wound FRP tank with approximately 6,000-gallon capacity, featuring a 10-foot diameter, 11-foot sidewall height, and maximum liquid level of 10 feet 6 inches. The tank must meet ASTM D3299 standards from an RTP-1 qualified manufacturer and include a reinforced concrete pad foundation, dome top configuration, and flat bottom design. Required accessories include a ladder, handrail, high-level switch, radar level transducer, overflow, vent, and lockable fill cabinet.

The tank specifications include comprehensive nozzle provisions for operational and instrumentation purposes: a 3-inch fill nozzle, 2.5-inch outlet, 3-inch drain, 4-inch overflow, 3-inch recirculation line, and 2.5-inch vent, along with instrumentation nozzles for a 6-inch radar level transmitter and 6-inch level switch. The equipment is designed to operate at atmospheric pressure across an ambient temperature range from 10°F minimum to 120°F maximum, with heat trace capability set at 60°F. Top and side manways measuring 30 inches and 36 inches respectively provide access for maintenance and inspection. Gasket materials must be EPDM or an approved equivalent to ensure operational integrity and chemical compatibility.
