Owner of Bergeson & Campbell, P.C. (B&C®), Lynn L. Bergeson has earned an international reputation for her deep and expansive understanding of the Toxic Substances Control Act (TSCA), the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), European Union Registration, Evaluation, Authorization and Restriction of Chemicals (REACH), and especially how these regulatory programs pertain to nanotechnology, industrial biotechnology, synthetic biology, and other emerging transformative technologies. Her knowledge of and involvement in the policy process allows her to develop client-focused strategies whether advocating before Congress, the U.S. Environmental Protection Agency (EPA), the U.S. Food and Drug Administration (FDA), or other governance and standard-setting bodies.

Ms. Bergeson counsels corporations, trade associations, and business consortia on a wide range of issues pertaining to chemical hazard, exposure and risk assessment, risk communication, minimizing legal liability, and evolving regulatory and policy matters pertinent to conventional, biobased, and nanoscale chemicals, particularly with respect to TSCA, FIFRA, Food Quality Protection Act (FQPA), REACH and REACH-like programs, and Occupational Safety and Health Administration (OSHA) matters.

She served as chair of the American Bar Association Section of Environment, Energy, and Resources, and has served in many Section leadership positions. She has served on the Board of Directors of the Environmental Law Institute, the NanoBusiness Commercialization Association, and the Product Stewardship Society, among other business and law organizations, and lectures and writes frequently on legal, regulatory, and science policy issues. Ms. Bergeson is also President of The Acta Group (Acta®), B&C's scientific and regulatory consulting arm, which assists chemical and product manufacturers in marketing and sustaining their products globally, and President of B&C Consortia Management, L.L.C., which helps the chemical industry leverage resources and maximize impact by forming consortia to achieve shared research, testing, regulatory, and access goals.

According to the Chambers USA Guide: "The universally highly regarded Lynn Bergeson of Bergeson & Campbell, P.C. has developed an enviable reputation in chemical and pesticide regulatory work, with particular expertise in nanotechnology. 'She is probably the premier pesticide lawyer in DC,' notes one impressed commentator. Peers predict that she is set to become 'one of the most important lawyers in America.'"

Representative Engagements:

  • Assists a global manufacturer of industrial and consumer products register and maintain chemical product approvals in all jurisdictions in which its products are marketed.
  • Among the first U.S. law firms to assist several manufacturers of nanoscale chemical products obtain approval for their innovations under TSCA, and have devised and maintained product stewardship programs in multiple global jurisdictions to manage these nanoscale products effectively.
  • Among the first law firms judicially to challenge a Significant New Use Rule (SNUR) issued under TSCA Section 5 to eliminate or lessen commercial restrictions placed on the manufacture, processing, and distribution of a new chemical substance.
  • Assists several biobased chemical manufacturers address difficult TSCA nomenclature and chemical identity issues and devise and implement product stewardship protocols to manage these products with downstream stakeholders.
  • Assists clients prepare and obtain approvals for chemicals produced by intergeneric microorganisms.
