A RAB is a community group which meets to discuss and receive information on environmental restoration (cleanup of contamination) projects at a military facility. What does a RAB do? A RAB enables local community members interested in environmental cleanup to receive from and exchange information with the facility and regulatory agencies managing environmental cleanup projects at Stockton AASF. At meetings, RAB members and the public can receive updates and ask questions on the status of the environmental cleanup program at Stockton AASF. Though RABs are not a decision-making group, RABs do give local community members the opportunity to have their voices heard and to provide valuable community insight to the facility and regulatory agencies.
