MI SB0058

Changes cleanup standard requirement so remedial actions must meet residential use criteria and restore aquifers to state drinking water standards unless technically infeasible, rather than allowing alternative cleanup categories based on property use.

Modifies cleanup category selection process to require the most stringent technically feasible cleanup category as the default, replacing the prior system where persons could propose their preferred category subject to department approval.

Revises technical infeasibility standards and processes for demonstrating when stricter cleanup standards cannot be achieved, including clearer definitions and grounds for making such determinations.

Updates groundwater-to-surface water interface (venting groundwater) compliance demonstrations to allow alternative monitoring points, ecological demonstrations, and modeling demonstrations in addition to traditional criteria-based approaches.

Clarifies land use restriction requirements and processes for recording restrictive covenants when cleanup to residential standards and drinking water restoration is technically infeasible, including enforcement provisions and acceptable alternative instruments.
