What is Risk Based Corrective Action (RBCA)?
RBCA (pronounced “Rebecca”) refers to a new philosophy for managing contaminant release sites. With this new approach, the amount of environmental management required to ensure protection of human health and the environment is based on a scientific assessment of the risks posed by the contaminants, both now and in the future. Environmental management always considers the risks of contaminants on a site. RBCA also considers the likelihood that people or environmental resources could be harmed by the contaminant. It achieves this by looking at the characteristics of the site, such as the type of soil, the location of water on the site and how the land is likely to be used in coming years. RBCA clean-up goals are based on reducing risks to low, acceptable levels. This may be achieved by reduction of contaminant concentrations and it may also involve reducing the potential for exposure. An industrial site destined for redevelopment as a playground would require more stringent environmental
