In May 2023, Madison Le will move from her position as Director of the New Chemicals Division (NCD) within the U.S. Environmental Protection Agency’s (EPA) Office of Pollution Prevention and Toxics (OPPT) to the Office of Pesticide Programs’ Biopesticides Division. As reported in our March 4, 2020, blog item, Le joined OPPT as Director of the then Chemical Control Division in 2020, a particularly challenging time. During her time as head of NCD, NCD has increased staffing, allowing it to increase throughput, developed new approaches, and shored up science, policy, and standard operating procedures. Ms. Le previously served as Director of the Fuels Compliance Policy Center within the Office of Air and Radiation. In that capacity, Ms. Le managed the implementation of EPA’s national fuels programs, including the Renewable Fuel Standard Program, Tier 3 Gasoline, Ultra-Low Sulfur Diesel, and Fuels and Fuel Additives Registration. Prior to working for EPA, Ms. Le worked for California’s Los Angeles County on engineering design projects for municipal solid waste landfills and wastewater treatment plants, including air quality modeling and permitting for stationary and mobile sources. Ms. Le holds an M.S. and B.S. in Environmental Engineering from the University of Southern California.
