ARSD 74:56:01:43. Off-site impacts and source investigation

As required by the department, all suspected releases requiring reporting under § 74:56:01:40 must be investigated and confirmed or disproved by the owner or operator to establish whether corrective action requirements must be followed. When a release of a regulated substance is suspected, the department may require the owner or operator to test the tanks and piping for tightness or structural soundness or require a site investigation to ascertain the location, magnitude, and effect of the leaking UST system.
