Marianne Lamont Horinko (born May 10, 1961) served as Acting Administrator of the United States Environmental Protection Agency (EPA) from July 14, 2003 to November 5, 2003 during the first term of President George W. Bush.
Prior to this appointment Horinko was Assistant Administrator for the Office of Solid Waste and Emergency Response (OSWER) at EPA, having been confirmed by the U.S. Senate on October 1, 2001.
[1] Horinko was an attorney at Morgan, Lewis & Bockius, involved in the areas of pesticides and hazardous waste counseling, Clean Water Act and Superfund litigation, and environmental audits in connection with business transactions.
She was responsible for launching the RCRA Policy Forum, a membership organization composed of federal and state governments, environmental groups, Capitol Hill staff, and industries interested in furthering constructive dialogue to improve the nation's waste programs.
[3] Back at EPA during her tenure as Assistant Administrator, Horinko refocused the goals of her office around five major priorities: Homeland Security/Emergency Response; One Cleanup Program; Land Revitalization; Energy Recovery, Recycling & Waste Minimization; a Retail Environmental Initiative (the Resource Conservation Challenge) and Workforce Development.
"In a summary of the rule, the EPA said it would improve 'clarity and consistency' of regulation, 'provide regulatory relief, and save affected facilities over $30 million'" by allowing industrial shop towels to be washed in water that would then go into municipal waste-water treatment systems.
[5] Steve Hunt, who won the nomination and whom Horinko then endorsed,[6] ultimately lost a close race in early January, 2010, to David W. Marsden (D-Fairfax), a result which "def[ied] recent voting trends that saw several Northern Virginia Republicans win big in November.
