Clean Harbors Updates Participation in Gulf Oil Spill Response

Clean Harbors, Inc. ("Clean Harbors") (NYSE: CLH) reported today that as the leading provider of environmental emergency response services in North America, the Company has been contracted to provide a variety of environmental response services throughout the Gulf of Mexico region to protect the area's natural resources from the effects of the ongoing oil rig spill.

Clean Harbors currently has deployed a large number of its own personnel and subcontractors to a variety of locations throughout the Gulf. As part of its engagement, it also has been tasked with recruiting and training residents of the affected Gulf areas to safely conduct oil spill clean-up along the coastline. Clean Harbors has been contracted by government agencies and private organizations to provide a wide range of support and logistical services. As part of its efforts, the Company is supplying equipment, including boats, containment boom, skimmers, and vacuum trucks, as well as recovery and treatment systems from its extensive equipment inventory. Clean Harbors is involved in many aspects of the spill response including containment, removal, disposal and recycling of the recovered oil.

"While the full scope of our participation in the clean-up efforts continues to evolve, we are providing this update on our activities in response to numerous inquiries from the media, investors and other stakeholders," said Alan S. McKim, Chairman and Chief Executive Officer. "Our customers' requirements will depend upon weather, tidal conditions and the amount of oil that ultimately strikes the coastline. Therefore, the duration of our contracts, staffing levels and dedicated equipment are subject to frequent change. However, we believe we have reached a point where we can quantify the potential near-term revenue impact from the spill."

"At this time, we are estimating that this event will result in an increase in second quarter 2010 revenues of 15 to 20 percent of the current First Call consensus estimate of $352.0 million," said James M. Rutledge, Chief Financial Officer. "Due to the fluidity of the situation, we do not anticipate providing any further financial updates beyond this range. We will share additional information when we announce our second-quarter financial results in early August."

"Our primary focus remains on addressing the needs of our customers, not only in the Gulf, but throughout North America," McKim concluded. "While this oil spill response requires us to marshal a substantial amount of resources, we anticipate no service disruptions to any of our ongoing client engagements in the Gulf region and throughout the U.S. and Canada. As we have proven through our emergency response work in the aftermath of Hurricane Katrina, and other oil spills in the Gulf region, we are able to draw significant leverage from our extensive network of assets and specialized equipment, and the recent addition of Eveready also affords us additional capacity."

Clean Harbors has created a link – www.cleanharbors.com/gulfresponse – on its website to keep investors and interested stakeholders updated on the Company's efforts. The site also contains links to other websites that provide spill-related information disseminated by the government and other agencies.
