IR 12 Map

Project A includes removal of excavated soil and debris currently stockpiled from previous phases of work at Westside SWDA (as indicated by the green polygon on map). The site will be graded with approximately 16,000 cubic yards of approved import fill. Noise associated with the heavy equipment backup alarms is anticipated during normal working hours. Dust control and air monitoring will be implemented to prevent airborne particulates and maintain public safety. The site surface will be restored with an approved grass seed mix compatible with adjacent areas.


Project B includes evaluations at seven subsurface radiological areas of interest (as indicated by the yellow circles on map). Prior to each evaluation, a temporary radiological control area will be established around each location. The evaluations will be performed by excavating and performing radiological surveys and scans of the excavated soil. All fieldwork will be conducted under third party oversight. The radiological isotope of concern for these seven areas of interest is Radium-226.
