A bill to amend 1994 PA 451, entitled “Natural resources and environmental protection act,” by amending section 20120a (MCL 324.20120a), as amended by 2024 PA 7.
The bills outline the establishment of cleanup criteria and approval of remedial actions by the Department of Environment, Great Lakes, and Energy (EGLE) for various categories, including residential, nonresidential, limited residential, and limited nonresidential areas. It allows for site-specific criteria and area-wide remedial action plans, emphasizing the use of reasonable and relevant exposure pathways. The bills mandate the use of toxicity values from the U.S. Environmental Protection Agency (EPA) and other recognized sources, with a structured process for selecting and applying these values. It also introduces a stakeholder process for public input when deviating from EPA values.
The legislation specifies that cleanup criteria must be based on human health risk assessments and considers factors such as exposure pathways and facility characteristics. It includes provisions for using probabilistic methods to evaluate environmental data and mandates public notice and stakeholder input for certain assessments. The bills also addresses the protection of groundwater, requiring that cleanup criteria for groundwater in aquifers align with state and federal drinking water standards unless site-specific criteria are approved.
