MIRBCA: EGLE’s New Risk-Based Corrective Action for LUST Sites

Who Is Affected?

The Michigan Department of Environment, Great Lakes, and Energy (EGLE) is in the process of introducing the Michigan-Specific Risk-Based Corrective Action (MIRBCA) to streamline cleanup efforts at leaking underground storage tank (LUST) sites. Instead of using broad contamination thresholds, MIRBCA allows for site-specific cleanup criteria based on detailed environmental assessments and site-specific information.

MIRBCA applies to environmental consulting firms, regulatory agencies, and site owners working on Part 213-regulated LUST sites. These guidelines help close Tier 2 sites by incorporating data-driven evaluations of soil and groundwater conditions.

Key Site-Specific Testing Under MIRBCA 

To determine the appropriate corrective actions, firms must evaluate: 

• USDA Soil Classification
• Porosity
• Moisture Content
• Bulk & Particle Density

Challenges in Meeting MIRBCA Requirements 

The biggest hurdle is access to specialized laboratory services capable of performing these tests accurately, quickly, and dependably. Additionally, obtaining proper soil samples, such as Shelby Tube samples, may be necessary for precise analysis. Our sister company MATECO Drilling can provide these sampling services if required.
