In operation since 1940, this base now hosts the 21st Tactical Fighter Wing. Under this program, the Department of Defense seeks to identify, investigate, and clean up contamination from hazardous materials. As part of IRP studies, the Air Force identified 12 areas where hazardous materials had been generated, stored, used, or disposed of. All require further investigation. Initially, the Air Force focused on five areas.
