Steve Morgan appointed chief compliance officer

Houston – On September 18, Waste Management announced the promotion of Steve Morgan to chief
compliance officer, overseeing all ethics and compliance efforts.

Prior to this position, Morgan served as vice president and assistant general counsel, leading WM’s
environmental and auditing teams. While he will continue in this role, he will also assume all chief compliance
officer responsibilities, which includes supervision of WM’s ethics department.

“The waste industry is highly regulated, meaning that compliance is critical,” said Rick Wittenbraker,
general counsel for Waste Management. “Since I joined the company in 2003, I have witnessed Steve’s
passion and commitment to environmental compliance matters. In our highly regulated business, compliance
is critical to our success as we deal with local, state and federal governments, as well as millions of customers
and other stakeholder groups.”
