Ladies and Gentlemen:

 

Pursuant to the telephone conversation this afternoon with Sherry Haywood, Staff Attorney, there is enclosed a letter to the Commission submitted by Clean Harbors, Inc. (the “Company”), both on its own behalf and on behalf of  its subsidiaries listed as Guarantor Registrants in the Registration Statement on Form S-4 described above. The letter confirms the matters described therein and requests that the effective date of such Registration Statement be accelerated so that the Registration Statement, as amended, shall become effective at 10:00 a.m. on Friday, November 6, or as soon thereafter as practicable.

 

As discussed with Ms. Haywood, the Company requests that the staff advise the undersigned by telephone (617-367-2500, ext. 104) when the Registration Statement has become effective. Please also contact either the undersigned or C. Michael Malm of this firm should you have any questions or requests for additional information with respect to this filing. Thank you for your assistance.

 

Very truly yours,

 

/s/ John Chambliss
