Note: The Agency has adopted Risk-Based Corrective Action (RBCA) Regulations to determine cleanup objectives if action levels are exceeded.

35 Illinois Administrative Code Part 742, Tiered Approach to Corrective Action Objectives (TACO) gives the owner/operator the option to decide if the Tier 1 levels are the action levels or they may choose to calculate a Tier 2or 3 cleanup objective and remediate to these levels if required.
