### HOUSEHOLDING
Some banks, brokers and other nominee record holders may be participating in the practice of “householding” proxy statements and annual reports. This means that only one copy of our documents, including the annual report to shareholders and proxy statement, may have been sent to multiple shareholders in your household. We will promptly deliver a separate copy of either document to you upon written or oral request to Clean Harbors, Inc., 42 Longwater Drive, Norwell, MA 02061, Attention: Executive Office, telephone: 781-792-5000. If you want to receive separate copies of the proxy statement or annual report to shareholders in the future, or if you are receiving multiple copies and would like to receive only one copy per household, you should contact your bank, broker or other nominee record holder, or you may contact us at the above address and phone number.
