House committee substitute makes the following changes to the 1st edition.

Deletes the proposed changes to GS 130A-336(b1) and instead modifies the proposed changes to GS 130A-335(a2) to provide that the Department of Health and Human Services, its authorized agents, and local health departments have no liability for wastewater system failures that are a direct result of evaluations conducted by a licensed soil scientist or licensed geologist under subsection (a2) (previously, limited immunity to local health departments and did not specify the evaluation's direct causation of a failure; also specifically included immunity from liability arising from the licensed professionals' site verification). Amends the act's long title.
