Replace JP-8 Hydrant Fuel Storage Tanks
Replace JP-8 Hydrant Fuel Storage TanksMountain Home Air Force Base, ID
Date Completed: May 28, 2014
New Construction consisted of 2 (ea.) 40,000 BBL bulk fuel storage tanks and 2 (ea.) 10,000 BBL jet fuel hydrant system operating tanks, all of which were constructed as above ground tanks with fixed roofs and floating pans. Concrete containment dikes were also constructed around each tank with a secondary containment membrane liner system. A new 3,000 (sf) fuel pump house was constructed with a pumping capacity of 1,800 gpm. The pump house included an automated PLC based pump control panel and was constructed to be easily converted to a type III hydrant fuel pump house. The new pump house is connected to an existing type I/type II fuel distribution system with 10 existing hose cart – (hot pit) outlets located on the aircraft apron. The pump house is also connected to a 5,000 gallon product recovery tank, two 10,000 BBL operating tanks, and a two position truck fill / offload stand.
Additionally, the pumphouse was constructed with an internal bypass and backflow pressure control valve which will enable it to be easily converted to a fully functional type III hydrant system in the future. The project also included renovation of the existing bulk fuel pumphouse with architectural and code compliant upgrades and a new pump control panel. Additional project features included: above ground and below ground fuel piping with supply and return lines between the pump house and all fuel storage tanks; a complete cathodic protection system for the bottom of the fuel storage tanks and all of the fuel piping; a completely new electrical system and annunciation control system meeting NEC class 1 division 1 requirements, an automatic tank gauge and annunciation system; a new storm drainage system around the entire site; painting of all new fuel tanks and fuel piping with fulltime QP-5 paint inspection; demolition and closure of two existing 36,000 BBL fuel storage tanks along with contaminated soils testing, handling and disposal of contaminated soil, and preparation of the tank closure reports for submission to Idaho Department of Environmental Quality.
This was a phased project which required construction to be completed in four consecutive phases. Phase I required the construction of the new pumphouse, one of the two 40,000 BBL fuel storage tanks and two of the 10,000 BBL fuel storage tanks. Phase I had to be commissioned and operational before Phase II could begin. Phase II included the demolition of one existing 36,000 BBL (partially buried) fuel storage tank.
Phase III included all new construction of the 2nd 40,000 BBL fuel storage tank and containment dike. Phase IV included demolition of the 2nd existing 36,000 BBL (partially buried) fuel storage tank and final site restoration.
