Norman Dupont


Norman (Norm) Dupont is a partner at Ring Bender, where he advises public and private clients in environmental matters and a variety of litigation matters.  Mr. Dupont has over 38 years experience in the environmental law field, including the Comprehensive Environmental Response, Compensation & Liability Act (“CERCLA”), the Resources Conservation and Recovery Act, amendments to the Solid Waste Disposal Act (“RCRA”), the Clean Water Act, the Porter-Cologne Water Quality Control Act, Proposition 65 claims, brownfield redevelopment projects, California Hazardous Substance Account Act (HSAA) claims, stormwater discharges from MS4 systems, and suits alleging common law tort or toxic tort claims.

Mr. Dupont has tried a variety of cases including environmental, antitrust, contract, labor and tort cases before both in bench trials and before juries. Among his recent cases are:

*Bradford v. City of Compton (2016-2022) Jury trial with a defense verdict in favor of municipal defendant on labor discrimination/retaliation claims. After remand from the Court of Appeal, a second trial resulted in verdict for plaintiff. In October 2021, the Court of Appeal reversed the jury verdict and thereby remanded the case for further proceedings.  Plaintiff has filed a petition for review to the California Supreme Court..

Edwards Lifesciences LLC v. Regional Water Quality Control Board (2020). Writ of administrative mandate challenging order issued by Regional Board in 2018 concerning real property in Orange County. The Superior Court granted the writ, and the Regional Board subsequently rescinded its order in lieu of any appeal.

*Hermosa Fitness LLP v. City of Hermosa Beach (2020-2021): Mr. Dupont served as co-counsel to plaintiff, which filed a writ of administrative mandate in state court together with a federal court section 1983 civil rights claim against the City of Hermosa Beach after a municipal resolution effectively closed Hermosa Fitness’ gym operating in the City. The writ of mandate was issued by the trial court, and the federal section 1983 case was mediated before a federal magistrate judge in the Central District of California and was settled in 2021.

*Orange County Water Dist. v. SABIC Innovative Plastics US, LLC (2011-2022) In 2013 an initial bench trial resulted in a defense verdict on state Superfund (HSAA) claims alleging groundwater against multiple corporate defendants. This decision was reversed in part by Orange County Water Dist. v. SABIC Innovative Plastics, US, LLC, 14 Cal.App.5th 343 (2017) and remanded back to the trial court. Currently a bench trial is proceeding before the Orange County Superior Court (Complex Civil Division).

Mr. Dupont is the Publications Officer for the Section of Environment, Energy and Resources of the ABA where he supervises all publications of the Section. He also serves on the ABA Standing Committee on Publications Oversight and on the separate ABA Cybersecurity Task Force. He is a member of the Orange County Bar’s environmental law section.

Mr. Dupont actively participates in his community. He currently serves on the Board of Directors for Women Against Gun Violence, a Los Angeles-based education and advocacy group which supports sensible gun regulation in the country’s second largest municipal jurisdiction. Previously, Mr. Dupont served as president of his local home owners association for approximately ten years.

Mr. Dupont has written and lectured extensively on a variety of environmental issues, including recent U.S. Supreme Court cases deciding environmental law issues.
