Item 2.01        Completion of Acquisition or Disposition of Assets.

On August 18, 2006, Clean Harbors, Inc. (the “Company”) purchased from SITA U.S.A., Inc., a Delaware corporation (“Seller”), all of the membership interests in Teris L.L.C., a Delaware limited liability company (“Teris”). The purchase was made in accordance with the purchase and sale agreement which the Company and Seller had entered into on May 3, 2006. The purchase price was approximately $52.7 million in cash, subject to a post-closing adjustment based upon the amount by which Teris’ net working capital as of the closing date exceeded or was less than $10.3 million. The Company now anticipates that adjustment will be determined within 135 days after the closing date.

By acquiring all of the membership interests in Teris, the Company indirectly acquired ownership of two licensed hazardous waste management facilities which Teris owned as of the closing.  These facilities consist of an incineration facility located in El Dorado, Arkansas, which has an annual practical capacity of approximately 80,000 tons, and a transportation, storage and disposal facility located in Wilmington, California.

The Company’s press release dated August 21, 2006, entitled “Clean Harbors Completes Acquisition of Teris L.L.C.,” including the “Safe Harbor Statement” contained therein, describe the acquisition and certain risks and uncertainties relevant to the acquisition.  A copy of that press release is attached hereto as Exhibit 99.1 and incorporated herein by reference.

The Company financed the acquisition of Teris using available cash and a $30.0 million term loan under the Company’s existing credit agreement.  That term loan bears interest, at the Company’s option, at either the Eurodollar Rate (as defined in the credit agreement) plus 2.5% per annum or the base rate plus 1.50% per annum.  The term loan will mature on December 1, 2010, and there will be no principal amortization prior to that date.

Other than in respect of the Company’s purchase of Teris, there is no material relationship between the Company and Seller.

Item 9.01       Financial Statements and Exhibits.

(a) and (b)  Financial statements of business acquired and pro forma financial information.

Financial statements of Teris L.L.C., and pro forma financial information giving effect to the acquisition, are not included herein but will be filed by an amendment to this report on Form 8-K not later than 71 days after the due date for the filing of this report.

(c)  Shell company transactions.

Not applicable.
