Case Study: Taking an 85 year old railyard from enrollment in a voluntary cleanup to no further action in ≈one year.

This is an old 60 acre railyard in Oregon, USA. The site owner went into an agreement with the State Agency under the State Voluntary Cleanup Program. A bit over a year later, the agency issued a conditional no further action (NFA) letter. In broad terms, the approach included addressing the risks of mobility (LNAPL migration) as well as demonstrating that mass losses due to natural processes (natural source zone depletion) occurred at rates that exceeded free product recovery (in operation since 1997 and into 2005).
