Installations have the choice of two automated applications to assist them in the implementation of relative risk: the Relative Risk Site Evaluation Program (RRSEP) and the Relative Risk Mapinfo Interface (RRMI). This article examines the Air Force's implementation of this guidance through the development of the Relative Risk Site Evaluation Framework at base closure sites managed by the Air Force Base Conversion Agency and by the Army Corps of Engineers in the restoration of formerly used defense sites (FUDS). groups to facilitate the prioritization of funding allocations. The resulting Relative Risk Site Evaluation Framework categorizes sites and areas of concern in the Defense Environmental Restoration Program (DERP) into high, medium, and low relative risk. In April 1994, the Department of Defense issued management guidance directing the Services to begin developing their environmental restoration program guidance using a relative risk evaluation framework. This work was performed under Federal Contract W9113M-09-C-0136 in support of the Radiance Technologies, Inc., prime contract from US Army SMDC, Huntsville, AL.

subtilis to less than 1 log at 100 min for 5 mW total LED power. Changing the peak wavelength by 7 nm to 377 nm decreased the kill of vegetative B. The starting concentration of each sample was on the order of 104 colony forming units per milliliter (CFU/mL) and the time required for complete kill was less than 100min when the peak wavelength was 370 nm for the four LED light source at a total LED power of 0.8 milliWatts (mW), decreasing to less than 75 min for a total LED power of 3 mW. subtilis) in phosphate buffered saline decreased when subjected to ultraviolet (UV) light from light emitting diodes (LEDs) in the presence of 0.01% Degussa P25 titanium dioxide (TiO2) as compared to a sample that contained bacteria only, a sample of bacteria that contained 0.01% TiO2, and bacteria that was subjected to the same UV light but. The concentration of vegetative Bacillus subtilis (B.
