SB 639: RELATING TO UNDERGROUND STORAGE TANKS.

Clarifies the level of environmental restoration that owners and operators of underground storage tanks or tank systems must satisfy in the event of a confirmed release of jet fuel.  Specifies the restoration condition and quality acceptable by the Department of Health shall include the complete removal of all jet fuel, including jet fuel additives and all compounds resulting from the degradation of jet fuel or jet fuel additives, or the reaction of jet fuel or jet fuel additives with water or other chemicals.  Establishes a rebuttable presumption that any detection of these contaminants in the vicinity of an underground storage tank or a tank system after a confirmed release is a result of the confirmed release.
