 the Lead Director, who is eligible to attend all committee meetings but may only vote on committee matters if he or she is a member of such committee. As a matter of practice, the Lead Director does not serve on any committees. Further, Mr. McKim, Mr. Battles, and Mr. Gerstenberg also do not serve on any committees.

The Board believes its current leadership structure to be the most appropriate for the Company at this time.

Mr. McKim, founder and former CEO of the Company, continues to serve as Executive Chairman of the Board. With over 40 year of experience, he possesses extensive knowledge of the Company's business and has an impressive track record in its management. As the Company's largest individual shareholder, Mr. McKim’s interests are also significantly aligned with those of the other shareholders. Additionally, the Board believes that the Company's Co-CEOs have demonstrated remarkable leadership. They have been Co-CEOs for two years and previously held significant leadership roles within the Company.

The Board also believes this structure is appropriate because as described below, all of the Company’s directors except for Mr. McKim, Mr. Battles, and Mr. Gerstenberg are “independent” as defined under New York Stock Exchange (“NYSE”) rules and, as described above, the Board has an independent Lead Director selected from among the independent directors and all of the committees of the Board consist exclusively of independent directors.

Corporate Governance Guidelines, Committee Charters, and Code of Ethics and Business Conduct

The Company’s Board has adopted Corporate Governance Guidelines, charters for each of the Board’s committees, and a Code of Ethics and Business Conduct which sets forth standards of ethical professional conduct for the officers, directors and employees of the Company and its subsidiaries. Each of those documents is posted on the Company’s website at www.cleanharbors.com under “Investors - Corporate Governance.” A copy of these documents may also be obtained without cost by writing to Clean Harbors, Inc., 42 Longwater Drive, Norwell, MA 02061, Attention: Executive Office. In the event that any waiver of the Code of Ethics and Business Conduct is approved by the Audit Committee or the full Board of Directors, such waiver would be posted on the Company’s website. In 2024, and through the date of this proxy filing, there have been no waivers granted.

#### Director Independence
The Corporate Governance Guidelines adopted by the Board require that a majority of the Board be “independent,” as defined by the rules of the NYSE
