Risk Communication comprises the formal and informal processes of communication among various parties who are potentially at risk from or are otherwise interested in the site. Throughout the risk assessment process, EPA will keep the public informed on issues concerning the site and provide guidance on how it will receive and respond to input from the affected community. Advisory groups are one example of the tools EPA may employ to communicate risk information including Biological Technical Assistance Groups or "BTAGs." In addition, the Agency will notify and communicate with the Natural Resource Trustees who have jurisdiction at the site regarding known or potential adverse effects on ecological receptors.
