House committee substitute to the 1st edition makes the following changes. Removes Section 2, which would have amended GS 130A-310.7(a) to provide that a landowner who purchases property with knowledge that disposal of hazardous substances or waste occurred on the property or with a reasonable basis for knowing that disposal of hazardous substances or waste occurred on the property is a responsible party if they conduct any activity that causes exposure to or migration of the existing contamination. Removes Section 8, which would have amends GS 14-130 to clarify that, for purposes of crime of trespass on public lands, “state-owned lands” includes lands subject to a conservation agreement held by the State or a State agency and that would have amended GS 1-539.1 by defining owner. Makes conforming, organizational changes.
