David Fischer counsels clients on environmental, policy, and health and safety matters, with a concentration on the Toxic Substances Control Act (TSCA) and the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). Having served as the Deputy Assistant Administrator for the U.S. Environmental Protection Agency's (EPA) Office of Chemical Safety and Pollution Prevention, as well as having held senior-level positions at the American Chemistry Council (ACC), David advocates for clients before the EPA and Congress.

In addition to TSCA and FIFRA, he has experience with numerous other statutes, including the Safe Drinking Water Act (SDWA), Emergency Planning and Community Right-to-Know Act (EPCRA), and the Food Quality Protection Act (FQPA).

David’s clients include domestic and international industrial and specialty chemical manufacturers and the trade associations which represent them. Clients seek his assistance on new chemical approvals, chemical and pesticide risk evaluations, and risk management rulemakings because of his deep understanding of EPA, its internal science policy apparatus, and its many organizational pieces that are collectively responsible for all aspects of TSCA and FIFRA. 

Prior to joining Keller and Heckman, David was the Deputy Assistant Administrator (DAA) for the Office of Chemical Safety and Pollution Prevention (OCSPP) at EPA. During his tenure as DAA, he was deeply involved in TSCA implementation, with a particular focus on risk evaluation of existing chemicals, and all aspects of FIFRA implementation. In addition, he worked with the Assistant Administrator on the technical and administrative aspects of OCSPP, an office with over 1,000 staff. He also assisted in matters pertaining to the Agency’s programs under multiple federal statutes including TSCA, FIFRA, FFDCA, and the FQPA, and provided policy advice and recommendations to the EPA Administrator. 

During his tenure at the ACC, David co-managed the Chemical Products and Technology Division (CPTD), where he led the implementation of the 2016 amendments to TSCA.

David is frequently invited to speak at conferences and has authored numerous papers on environmental matters.
