LANL News:

The Department of Energy National Nuclear Security Administration’s (DOE/NNSA) Los Alamos Field Office has issued a Floodplain Assessment for the Technical Area 72 Outdoor Live Fire Range Storage Units Installation Project for a 15-day review and comment period commencing with publication of this notice.

DOE/NNSA is proposing storage unit installation in lower Sandia Canyon at Technical Area (TA) 72 at the Outdoor Live Fire Range facility at Los Alamos National Laboratory (LANL). Prefabricated metal transportainer type storage units are proposed for installation at four locations throughout the TA-72 Outdoor Live Fire Range facility to store firing range supplies (e.g., targets, hand and power tools, and other consumables). 

Currently, the facility has minimal capacity for storing the materials and supplies used at each range. Providing on-site storage will reduce overall cost and impact to programmatic schedules. Three of the four proposed locations occur in or near the Sandia Canyon 100-year floodplain.

After the close of the comment period and prior to issuing a Floodplain Statement of Findings, DOE/NNSA will reevaluate the alternatives to the proposed action in a floodplain, identify mitigation measures that would avoid or minimize impacts to the floodplain, and take into account all substantive comments received during the comment period.
