	Registration Statement on Form S-3 File No. 333-262605

VIA EDGAR

Ladies and Gentlemen:

Reference is made to our letter, filed as correspondence via EDGAR on March 8, 2022, in which we requested the effectiveness of the Registration Statement on Form S-3 (File No. 333-262605) of the Registrant (the “Registration Statement”) be accelerated so that the Company’s Registration Statement be declared effective at 4:30 p.m., Eastern Time, on March 10, 2022 or as soon thereafter as may be practicable. We are no longer requesting that such Registration Statement be declared effective at that time and we hereby formally withdraw our request for acceleration of the effective date.

Very truly yours,

HERITAGE-CRYSTAL CLEAN, INC.
