Mackenzie’s practice includes both litigation and regulatory matters arising under FIFRA, the Clean Water Act, and related environmental laws.
She is passionate about conserving air, water, wildlife, and land for future generations, and enjoys helping clients navigate and enforce the detailed framework of environmental law because she believes compliance is key to preventing adverse impacts to the environment.
Mackenzie is a co-chair of Beveridge & Diamond’s Industrial Hemp & Cannabis industry team. She advises clients, and regularly writes and presents, on federal and state environmental regulations impacting this thriving industry.
Under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), Mackenzie represents pesticide companies in data compensation arbitrations, focusing on defending the rights of data owners against follow-on registrants of pesticides. She has also worked extensively with task forces comprised of national and multinational companies of all sizes that operate as joint ventures or limited liability companies to generate data and other information to meet government requirements under FIFRA.
Among the wide range of issues under the Clean Water Act that Mackenzie has handled are assisting companies with responses to Clean Water Act Section 308 information requests and Clean Water Act Section 404 compensatory mitigation requirements.
Mackenzie also defends public utilities against toxic tort claims. She was part of the team that obtained a defense judgment after a three-week trial regarding claims alleging that the client supplied corrosive water to apartment buildings. The case, Cormier v. D.C. WASA, 2011 D.C. Super. Lexis 7, 84 A.3d 492 (2013), was successfully upheld on appeal.
