This operations and maintenance OM manual has been created as a guide for monitoring and maintaining the performance of the expanded-scale bioventing blower system at the Bulk Petroleum, Oils, and Lubricants POL Storage Area POL yard, Malmstrom Air Force Base AFB, Montana. This site is located in the northeastern portion of the base. Record drawings for the expanded-scale bioventing system, installed at the POL yard Site PS-4 in October 1996 in accordance with the site remedial action plan, are provided in Appendix A of this OM manual. At this site, bioventing is the forced injection of fresh air to enhance the supply of oxygen in subsurface soils for in situ bioremediation. A blower system is used to inject air into the soil, thereby supplying fresh atmospheric air with approximately 20.8 percent oxygen to contaminated soils. Once oxygen is provided to the subsurface, indigenous aerobic bacteria biodegrade fuel residuals. Aerobic biodegradation of fuel compounds in soil is much more efficient than anaerobic biodegradation, which occurs in oxygen-depleted soils.
