HI SB639

Requires owners or operators of underground storage tanks with confirmed releases to restore the environment to standards acceptable to the Department of Health, with specific focus on jet fuel contamination.

Mandates cleanup and removal of jet fuel, jet fuel additives, and jet fuel degradation compounds to levels below detection limits of the best available technology, with the goal of complete remediation.

Establishes a rebuttable presumption that any detection of jet fuel, jet fuel additives, or jet fuel-derived compounds in groundwater or the environment near an underground storage tank after a confirmed release is presumed to result from that release.

Applies to underground storage tank or tank system releases and requires the Department of Health to adopt rules implementing these requirements pursuant to chapter 91.

Takes effect July 1, 3000.
