Remedial Action Workplan, 1964 B-58 Accident Site, Grissom Air Reserve Base, Bunker Hill, Indiana
Abstract
On December 8, 1964, during a routine Operational Readiness Inspection, a B-58 strategic bomber skidded off the runway at Bunker Hill AFB, IN (later named Grissom Air Force Base). The consequence of the accident was a fire and destruction of five nuclear weapons on the aircraft. The high explosives in the weapons did not detonate, but melted and burned, leaving some residual radioactive contamination in soils adjacent to the runway. The contaminated area was excavated and buried along with the aircraft wreckage at a different location on base. In 1999, AFIERA performed a radiological characterization of the site (IERA-SD-BR-TR-2000-0002). The results of the survey confirm that a small area of the site investigated contains depleted uranium contamination. The investigation area was about 8,800 square meters and had an estimated excess surface activity concentration of 1 pCi/g averaged over the entire area. Within this area, the contamination zone is limited to an area of 1000 square meters, with a mean excess uranium activity concentration of 7 pCi/g. This report details a remedial action plan for the site. The remedial action work plan details tasks to be accomplished by AFIERA and a private contract organization. Included in the plan are details on 1) pre-remediation site survey, 2) soil removal activities, 3) remedial action support surveys 4) final status soil sampling and 5) soil backfill of the remediation area.
