Obvious Contamination Clause Samples
Obvious Contamination. If free product, strong petroleum product odors, stained soil or backfill, or other conditions make it obvious that a release from the tank has occurred, then it is necessary to report the release immediately to the DNR in accordance with attachment 3. It is not necessary to complete the site assessment sampling. However, collect at least one sample of the contaminated soil for laboratory analysis to confirm the release in accordance with the procedures under “▇▇▇- ple Collection−−Obvious Contamination” and complete the closure documentation. Report the specific cause of the release (e.g. hole in tank, loose piping), if known.
