House Bill 6024 Summary

• Requires remedial actions to achieve cleanup criteria for unrestricted residential use and restore affected aquifers to state drinking water standards, unless technically infeasible.

• Establishes a default cleanup category of "residential" unless technical infeasibility requires selection of the most stringent technically feasible cleanup category instead.

• Creates alternative compliance pathways for venting groundwater through groundwater-surface water interface (GSI) criteria, including ecological demonstrations, modeling demonstrations, and alternative monitoring points.

• Permits land or resource use restrictions (recorded as restrictive covenants) to limit exposure when meeting residential cleanup standards is technically infeasible, with specific recordation and notice requirements.

• Applies retroactively to allow persons already performing response activities under prior agreements or orders to adopt the bill's provisions for venting groundwater remediation.
