CX-008823: Categorical Exclusion Determination

High Pressure Fire Loop and Lead-In Replacement in the MAA - Amendment 01
CX(s) Applied: B5.4
Date: 05/29/2012
Location(s): Texas
Offices(s): Pantex Site Office

Additional sections of the high pressure fire loop (HPFL) main line pipe would be replaced in Zone 12 South. Four options are being proposed, and pending bids from the subcontractor on one or more of the four options would be chosen for completion. This would extend the period of performance, pending which options are chosen. The scope of work associated with this amendment is identical (mainline pipe, valves, and hydrants) to the original scope, it only increases the area/length of deteriorated pipe being replaced. The subcontractor would use Horizontal Directional Drilling (HDD) to excavate and pull in the mainline pipe.
