Pete Nyquist

Chair, Environmental Practice Group
Fax 310-201-2364


Pete Nyquist chairs Greenberg Glusker’s Environmental Practice Group, comprised of nine full-time environmental attorneys. He was named by Best Lawyers in America as 2020 “Lawyer of the Year” for Environmental Law in Los Angeles and has been perennially listed in Chambers USA for Environment (since 2007) and in Best Lawyers for Environmental Law and Environmental Litigation (since 2012). The National Law Journal identified Pete as a “Trailblazer” in Energy and Environmental Law. As one client observed, “the more complex the issue, the more his guidance is invaluable to us. He keeps us on track and doesn't let any detail drop.” (Chambers USA, 2017).

His practice focuses on directing complex environmental litigation in federal and state court under CERCLA, RCRA, the Clean Water Act, and related claims for cost recovery or damages. Currently, Pete is part of the trial and strategic advisory team for Occidental Chemical Corporation in connection with the Diamond Alkali Superfund Site in Newark, New Jersey, where USEPA Region 2 plans to implement a dredge and cap remedy for the lower 8.3 miles of the Passaic River. He represents San Diego Gas & Electric in connection with ongoing investigative and cleanup activities to address alleged sediment contamination in the San Diego Bay from decades of industrial activities.

Pete also represents clients in a variety of matters involving investigation, remedial or corrective action requirements at contaminated sites, including agency oversight and enforcement proceedings. He regularly interfaces with USEPA, Cal-EPA, the Department of Toxic Substances Control, and the regional water quality control boards, and has represented clients in numerous administrative proceedings, appeals and writ actions challenging improper agency actions.

Pete co-chaired the California Lawyers Association (CLA) Yosemite Conference, nationally recognized as the largest and most prestigious gathering of California’s leaders in environmental law, and served on the Executive Committee of the California Lawyers Association Environmental Law Section.  He is a former Chair of the Los Angeles County Bar’s Environmental Law Section and remains a member of its Executive Committee. Pete has actively participated in and supported various community and charitable organizations, including coaching youth sports for over 10 years and serving on the Board of Trustees for his daughters’ former school. He remains an avid skier and is somehow clinging to a single-digit golf handicap.
