#### Board Committees
The Board has established four standing committees: the Audit Committee, the Compensation and Human Capital Committee, the Corporate Governance and Sustainability Committee, and the Environmental, Health, and Safety Committee. The Board has determined that each committee of the Board consists solely of non-employee “independent directors” as defined by the NYSE rules which are applicable to membership on such committees, and that each committee member is free of any relationship that would interfere with his or her ability to exercise independent judgment. Based upon their training and experience, as described below under “Election of Directors,” the Board has also determined that Marcy L. Reed and Andrea Robertson, who are now members of the Audit Committee, each qualify as an “audit committee financial expert” as defined by Item 407(d)(5)(ii) of Regulation S-K under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and that Karyn Polito and Shelley Stewart, Jr. the other current members of the Audit Committee, are financially literate as required by the NYSE listing rules. All members of the committees are appointed by the Board, and each committee operates under a charter approved by the Board and available on the Company’s website at www.cleanharbors.com under “Investors - Corporate Governance.” Copies may also be obtained without cost by writing to Clean Harbors, Inc., 42 Longwater Drive, Norwell, MA 02061, Attention: Executive Office.
