Published with the listing Evidence: publisher-reported

Overlapping the waterbody's shape Evidence: spatial

Industrial stormwater facilities

Evidence: identification corroborated

Shows: the facility named this waterbody as its receiving water in SMARTS, and the name and the facility's location are consistent with it. Does not establish: a discharge pathway, a discharge of any pollutant, or a cause of the listing.

Evidence: geographic proximity

Shows: the facility's reported location is within 1 km of the waterbody's mapped shape. Does not establish: that the facility discharges to this waterbody, or any other relationship.
