What it would have done
Summary by the , the Legislature's nonpartisan drafting office. It's their wording, not ours.
Under this bill, if the Department of Natural Resources finds that there has been an exceedance of groundwater standards or of any standard for perfluoroalkyl or polyfluoroalkyl substance (commonly known as PFAS) in a proposed or promulgated DNR rule, DNR must notify the county health department, tribal health department, and county land and conservation department in the affected county. DNR must also notify the county health department, tribal health department, and county land and conservation department in any adjacent county that DNR determines may be negatively affected by the exceedance. The bill requires DNR to provide these notices within seven business days after verifying that an exceedance has occurred. The bill also requires DNR to create and maintain a notification system for notifying county health departments, tribal health departments, and county land and conservation departments of the types of exceedances that trigger the notice requirement.
