HRL responded to a drilling rig rollover. The truck driver transporting the rig cut the corner too short causing it to roll into a beaver pond and spill hydraulic oil. The pond was bermed off and the free oil was removed by skimming and a vac truck. The challenge was to get the oil removed prior to winter weather which rendered the site in-accessible. The process took over 2 weeks to complete and resulted in successful removal of the oil.
