American Ecology Appoints James Baumgardner President and Chief Operating Officer

American Ecology Corporation (NASDAQ: ECOL) (the "Company") today announced that its Board of Directors has appointed James R. Baumgardner to the newly created position of President and Chief Operating Officer, effective January 5, 2009.

Baumgardner will report to Stephen Romano, Chairman and Chief Executive Officer, and will be responsible for sales and marketing as well as disposal site operations. As a member of the senior management team, he will also help plan and execute strategic initiatives including, but not limited to, identifying, acquiring, and integrating businesses to fuel future growth. Baumgardner rejoins the Company after previously serving as Senior Vice President and Chief Financial Officer from 1999 to 2006. He played a central role in the successful acquisition of the Company's Grand View, Idaho facility in early 2001.

"We are delighted to have Jim Baumgardner return to American Ecology," commented Romano. "Jim brings an impressive combination of financial, strategic, and business operations expertise to the Company. This, combined with his demonstrated capital markets and acquisition experience, makes him well suited to this new role within the Company. He is also uniquely prepared to hit the ground running, having worked with American Ecology's management team, customers and investors in the past."

From 2006 to 2008 Mr. Baumgardner, age 46, was Senior Vice President and Chief Financial Officer with SECOR International, Inc. ("SECOR"), a Redmond, Washington based provider of environmental consulting services. SECOR, previously owned by a Washington, D.C. private equity firm, was sold to a large NYSE-listed company in early 2008. While at SECOR, Mr. Baumgardner was pivotal in improving operational and financial management.

Prior to joining American Ecology in 1999, Mr. Baumgardner held various positions in corporate banking and corporate treasury. Mr. Baumgardner holds a MBA and BS from Oregon State University, where he was also a two-time All American wrestler. He is a member of the Oregon State University Athletic Hall of Fame.
