If the subject report could not be filed without unreasonable effort or expense and the registrant seeks relief pursuant to Rule 12b-25(b), the following should be completed. (Check box if appropriate)






The reasons described in reasonable detail in Part III of this form could not be eliminated without unreasonable effort or expense;

Clean Harbors, Inc. (the “Company”) has notified its lenders that the Company did not satisfy the Consolidated EBITDA covenant contained in the Company’s outstanding loan agreements for the fiscal quarter ended March 31, 2003, and has been in discussions with its lenders concerning a proposed waiver and amendment of such covenant. Such discussions have not yet been resolved, and the Company has therefore determined that it should delay the filing of its Form 10-Q for such fiscal quarter so that such filing can reflect the results of such discussions.
