The Department of Energy National Nuclear Security Administration’s (DOE/NNSA) Los Alamos Field Office has issued a Floodplain Statement of Findings for the installation of storage units 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 Firing Range 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. DOE/NNSA has reevaluated the Proposed Action and found that there are no alternatives that would locate the Proposed Action outside a floodplain and identified mitigation measures that would avoid or minimize impacts to the floodplain.
DOE/NNSA did not receive any public comments during the 15-day Floodplain Assessment public review and comment period. Upon completion of the Proposed Action the floodplain will retain the same values and functions as present prior to the fence installation.
