Contamination status is not in this series. this counts registered tank SITES, not releases or cleanups; a record is not a finding that land is contaminated. It is absent rather than estimated.

What this counts

The counting rule, so you can disagree with it.

Counts REGISTRY RECORDS held in the SCDES UST registry as of the date shown — NOT a determination that any site is leaking or clean. A record is a regulated tank facility on file.
