Federal Contaminated Sites Action Plan (FCSAP) Decision-Making Framework, Version 4.1

Executive summary

The Decision-Making Framework (DMF) outlines the 10 steps in the lifecycle of a federal contaminated site. Step 1 of the lifecycle is identifying potentially contaminated sites (in other words, a suspected site). The lifecycle ends when the contamination of an identified site is no longer a concern.

The DMF highlights the key decisions that must be made at each step.

Not all sites will go through all 10 steps and many sites may not require clean-up or use of risk reducing activities (Steps 7 to 10). The steps to assess a site (Steps 1 to 6) may be enough to determine that the level of contamination (if any) is not a risk to human health or the environment. The DMF helps make clear when a site should proceed to the next step or when it can be closed because it is no longer a concern.

This guidance document is written for federal employees and consultants working on federal contaminated sites. It can also be helpful for students learning about the contaminated sites field.
