Environmental assessments help determine compliance with current environmental regulations. The U.S. Air Force, U.S. Army, Defense Logistics Agency, and Corps of Engineers (Civil Works) have adopted environmental compliance programs that identify compliance problems before they are cited as violations by the U.S. Environmental Protection Agency (USEPA). Since 1984, the U.S. Army Construction Engineering Research Laboratories (USACERL), in cooperation with numerous Department of Defense (DoD) components, has developed environmental compliance assessment checklist manuals. The Environmental Assessment and Management (TEAM) Guide was developed for use by all DoD components. Currently there are five participating DoD components: the Air Force, Air National Guard, Army, Civil Works, and Defense Logistics Agency (DLA). These agencies have agreed to share the development and maintenance of this Guide. The Guide combines Code of Federal Regulations (CFRs) and management practices (MPs) into a series of checklists that show legal requirements and the specific operations or items to review. TEAM Guide is supplemented by DoD component-specific manuals detailing DoD component regulations and policies. The California Supplement was developed to be used in conjunction with the TEAM Guide, using existing California state environmental legislation and regulations as well as suggested management practices.
