A Restoration Advisory Board (RAB) is a forum composed of representatives of the Department of Defense (DoD), the U.S. Environmental Protection Agency (EPA), state and local governments, tribal governments, and the affected community. RAB members provide their individual advice to the Installation Commander concerning environmental cleanup at military installations. The RAB should reflect the diverse makeup of the community, give all stakeholders the opportunity to participate in the cleanup process, monitor cleanup progress, and provide the opportunity to make the community views known to the decision-makers. Technical Assistance for Public Participation (TAPP) is a new DoD program aimed at providing community members of RABs and Technical Review Committees (TRCs) with access to independent technical support through the use of government purchase orders. The TAPP program is designed to help community members understand scientific and engineering issues pertinent to the installation's environmental restoration activities.
