Clean Harbors Reports Purchase of Evergreen Oil

Clean Harbors, Inc. (“Clean Harbors”)

, the leading provider of environmental, energy and industrial services throughout North America, today announced that it has acquired Evergreen Oil, Inc. out of bankruptcy through the U.S. Bankruptcy Court for the Central District of California. Evergreen Oil is a California-based environmental services company that is one of the state's largest collectors of waste oil and runs the only re-refinery in the state. Clean Harbors is funding the $60 million transaction through available cash on its balance sheet. The acquisition of Evergreen Oil is beneficial to Clean Harbors on a number of fronts: * expands Clean Harbors' geographic footprint in re-refining to include coverage in the Western U.S. – complementing its Indiana facility in the Midwest and Breslau facility in Eastern Canada; * provides Clean Harbors with the second-largest collector of waste oil in California; and * provides Clean Harbors with a number of valuable ancillary waste assets, including a permitted Treatment, Storage and Disposal Facility (TSDF).
