For the U.S. Army Corps of Engineers–Omaha District, EA completed an interim removal action, as a non-time critical removal action, to achieve site closeout at two munitions response sites (a former munitions dump and a portion of a former skeet range) at Ellington Field Joint Reserve Base, Air National Guard, Texas. The objective was to remove subsurface munitions and explosives of concern, munitions debris, and lead-contaminated soil by means of mechanical excavation, sifting, offsite soil disposal, and metal recycling/smelting. Project deliverables included Engineering Evaluation/Cost Analysis, Action Memorandum, Explosives Safety Submission, Work Plan, Site-Specific Final Report, After Action Report, Proposed Plan, Record of Decision, and a No Further Action–Explosives Safety Submission. After initiation of site activities, and upon identification of a high explosive fragmenting munitions and explosives of concern item, the Explosives Safety Submission was amended and operations were resumed with a longer-reach armored excavator and reconfigured sifting plant with an inspection-line fragmentation barrier to safely complete excavation and sifting. In total, EA excavated more than 16,000 cubic yards of soil and sifted/removed more than 4,000 items (20,000 pounds) of munitions debris over a 6-month period. Following completion of the interim removal action, EA re-paved the road and restored the site to pre-existing conditions and prepared accompanying as-built drawings. All project objectives were achieved with quality assurance acceptance and zero safety incidents in over 11,000 man-hours of fieldwork.
