Ladies and Gentlemen:

         Pursuant to Rule 461 under the Securities Act of 1993, as amended,
Clean Harbors, Inc. (the "Company"), both on its own behalf and on behalf of its

become effective at 2:00 p.m. in the afternoon of Thursday, September 29, 2005
or as soon thereafter as practicable.

         The Company hereby acknowledges that (i) should the Commission or the
staff acting by delegated authority declare the Registration Statement
effective, it does not foreclose the Commission from taking any action on the
filing, (ii) the action of the Commission or the staff acting by delegated
authority in declaring the Registration Statement effective does not relieve the
Company from its full responsibility for the adequacy and accuracy of the
disclosure in the Registration Statement, and (iii) the Company may not assert
the staff's comments and the declaration of the Registration Statement's
effectiveness as a defense in any proceedings initiated by the Commission or any
person under the United States' federal securities laws. The Company also hereby
confirms that the Company and the Registrant Guarantors are aware of their
responsibilities under the Securities Act and the Exchange Act as they relate to
the proposed public offering of the securities specified in the Registration
Statement.

                                         Very truly yours,

                                         CLEAN HARBORS, INC.
