  • Chief Accounting Officer Eric Dugas Named EVP and Chief Financial Officer
  • EVP Brian Weber Appointed President of Safety-Kleen Sustainability Solutions

Clean Harbors, Inc. (“Clean Harbors”) (NYSE: CLH), the leading provider of environmental and industrial services throughout North America, today announced that it has appointed Eric Dugas as EVP and Chief Financial Officer, effective March 31, 2023. Dugas will succeed Michael Battles who, as previously announced, will become co-CEO with Chief Operating Officer Eric Gerstenberg on that date.

“Since his arrival in 2014, Eric has proven himself as a thoughtful and talented finance leader,” Battles said. “Over the past nine years, he has already participated in many of the key elements of being a public company CFO, including debt raises, equity conferences and close engagement with the operational business leaders. Eric is a strategic thinker who during his time with the Company has gained a strong understanding of the business and markets in which we operate, has deep knowledge of accounting rules for our industry and carries a strong capital allocation discipline. He will be a great business partner to the organization in his well-earned new role.”

Dugas was named CAO shortly after joining the Company. Dugas spent more than a decade at Deloitte & Touche before joining the Company. In 2019, he completed the Advanced Management Program at Harvard Business School. Dugas holds a Bachelor of Science in Accounting from Boston College and is a Certified Public Accountant (CPA).

The Company also announced today that EVP of Corporate Planning and Development Brian Weber has been named EVP and President of the Safety-Kleen Sustainability Solutions (SKSS) segment.

“Sustainability continues to be a growing part of the Clean Harbors story and we see significant opportunity to expand our SKSS business in both scale and scope,” said Gerstenberg. “Given his long operational experience with the organization, understanding of customer needs and business development expertise, Brian is the right person to spearhead the next stage of growth in SKSS. Brian has been successful at every level of the organization during his three decades with the Company that includes overseeing our used motor oil collection business. We are confident that SKSS will benefit from his stewardship and he will derive additional shareholder value from those assets.”

Weber has been with Clean Harbors since 1990. He has served in a variety of senior management positions during that time and most recently was the Company’s Executive Vice President of Corporate Planning and Development. Weber holds a Bachelor of Science degree in Business Management from Westfield State College.
