Contracting: Harbor Industrial Services, Inc.

Clean Harbors, Inc. (NASDAQ:CLHB) today announced the creation of a new subsidiary to provide industrial services throughout the United States, which would include chemical cleaning and specialty line cleaning and video camera monitoring/inspection of industrial lines.

Alan S. McKim, Chairman and CEO in making the announcement stated: "I am very excited about the prospects for this new subsidiary ---- Harbor Industrial Services, Inc. (HISI). There are abundant opportunities available within this new business segment. The nature and type of work aligns itself with Clean Harbors' capabilities and experience and more importantly, provides the customers we service so well today with another service line from a vendor they trust and respect. This new company will not only expand our capabilities within our current customer base but will create new business activities for us throughout the country."

"Clean Harbors has long been recognized as a leader in emergency response and in providing premiere customer service in pre-planned field service type work. As an example, chemical cleaning is normally time sensitive, requires extensive experience in managing large field crews and requires knowledge of chemical treatment. Clean Harbors has been doing all of this for twenty years and is one the most qualified environmental service companies in the treatment of hazardous chemicals. It only makes sense that we expand our business line to include industrial type services."

"Over the past 5 years our customers have been asking us to become involved in this type of field work. Most of the customers recognize the fact that we have the highest health & safety standards and want to maintain these standards for any and all work completed at their facilities. We expect to provide quality service in a timely fashion with all the Clean Harbors standards in place."

Mr. McKim also announced the appointment of Stephen Dovell as the President of Harbors Industrial Services, Inc. "I have asked Stephen to lead this new organization because he has been a successful, steady manager within Clean Harbors for 15 years. Stephen Dovell, formally Vice President of Plant Operations has been a key figure in the growth and development of Clean Harbors TSDF's including the Kimball incinerator in Kimball, Nebraska."
