MIRBCA: Background, Development, and Implementation

Presented by:

Steve Beukema, Ph.D.

In July of 2025, the Michigan Department of Environment, Great Lakes, and Energy (EGLE) Remediation and Redevelopment Division (RRD) published its Michigan Risk-Based Corrective Action (MIRBCA) guidance document and report forms. The development of MIRBCA is the culmination of several significant policy and technical changes implemented by the RRD from 2022 to 2025 as it reevaluated the implementation of the Leaking Underground Storage Tanks (LUST) program to increase program efficiency and to reduce Michigan's backlog of open LUST sites, which is the 2nd highest backlog in the nation.

To develop the MIRBCA guidance and report forms, Michigan worked with an ASTM International certified RBCA trainer and also evaluated RBCA guidance documents and report forms from several other states. The resulting MIRBCA documents align with the ASTM RBCA process, are similar to other RBCA-implementing agencies, and are customized to follow Michigan's environmental laws and policy decisions.

The MIRBCA process is risk-based and exposure pathway-specific. In the MIRBCA process, site data are collected as part of a site assessment. The data are used in a risk assessment to evaluate risk, which involves developing exposure models for onsite and offsite exposure for current use and future use. Critical elements of complete pathways include the exposure domain, point of exposure, point of compliance, and source area. Risk-based target levels (RBTLs) are developed and applied based on the exposure model and the elements of the RBTLs. For each exposure scenario, a representative concentration for each chemical of concern is compared to the RBTL in a tiered approach. Tier 1 is a "screening level" approach that uses a generic exposure model for future use. Tier 2 is a site-specific approach outlined in the MIRBCA guidance document and report forms. Tier 3 is any technically defensible approach for most pathways. Any unacceptable risks must be appropriately managed by performing corrective actions.

Implementing Part 213 using the MIRBCA guidance and report forms will likely results in a decrease in the need for restrictive covenants, a decrease in the time required to prepare or audit reports, and in predictable report and audit outcomes, thereby increasing the efficiency in performing corrective actions under Part 213.
