ITEM 1C.    CYBERSECURITY

Clean Harbors recognizes the critical importance of developing, implementing and maintaining cybersecurity measures to safeguard our information technology. The Company has integrated cybersecurity risk management into our overall risk management framework to collectively assess and respond to operational, financial and cybersecurity risks.

Board of Director Oversight

The Board of Directors is acutely aware of the critical nature of managing risks associated with cybersecurity threats. The Board, led by the Executive Chairman Alan McKim, who is also the Chief Technology Officer of the Company, has primary oversight responsibilities for cybersecurity risks and therefore has established oversight mechanisms to ensure effective governance in managing risks associated with cybersecurity threats.We have a special subcommittee of the Board of Directors with the goal of reviewing the Company’s overall cybersecurity risk and response landscape. The special Cybersecurity subcommittee is comprised of board members with diverse expertise including risk management, technology and finance, with two members holding Cybersecurity Oversight Certificates issued by the National Association of Corporate Directors and Carnegie Mellon University. The Chief Information Security Officer (“CISO”) and Chief Information Officer (“CIO”) provide comprehensive briefings throughout the year to the Cybersecurity subcommittee, which meets quarterly. The chair of the Cybersecurity subcommittee provides updates on the subcommittee’s activities to the Board of Directors and, from time to time as warranted, the CISO and CIO will present to the full Board of Directors as well. The briefings include the current landscape of cybersecurity risks and emerging threats, relevant Company infrastructure and tools employed to address these risk and threats, status of ongoing initiatives, incident reports and learnings and compliance with regulatory requirements and industry standards.

Management's Oversight and Responsibilities
