Some of the spray got onto vegetation outside the station on US forsest service property. Us forest service oversaw the removal (mowing) collection and disposal of the contaminated vegetation. Free product was recovered with vac trucks and returned to the pipeline system. Approximately 170 yards of contaminated soil was excavated from station grounds and has been disposed of.
