What is being done to minimize the disturbance of NOA deposits, or rock formations that may contain NOA, in Placer County?

The District believes that the best and most effective approach to minimizing and preventing impacts from naturally-occurring asbestos is a proactive program designed to minimize and control soil disturbance and thereby limit the release into the air of fine particulate matter, including any asbestos fibers that may be present. This approach is one that is endorsed by the conclusions of the Agency for Toxic Substances and Disease Registry's Health Consultation for El Dorado Hills, El Dorado County, and through the State Air Resources Board’s adoption of regulations that the District enforces to control and manage dust in areas where Naturally Occurring Asbestos (NOA) may be present.
