Clarifies the level of environmental restoration owners and operators of underground storage tanks or tank systems that had a confirmed release must satisfy by requiring the removal of all jet fuel, including 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.
