Pete Nyquist is a partner in and Chair of Greenberg Glusker’s Environmental Practice Group. Pete has been annually listed in Chambers USA and The Best Lawyers in America as among the top environmental lawyers in California. As one client observed in a Chambers USA interview, “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.”

His practice covers a broad range of environmental matters, including federal and state Superfund and contaminated sites, cost recovery and citizen suit litigation, administrative and enforcement matters before federal and state regulatory agencies, water quality, indoor air quality (e.g., vapor intrusion), and M&A/transactional support.

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

Pete has represented clients at many of California’s most complex federal and state Superfund, RCRA and sediment cleanup sites.  Additionally, he advises clients regarding compliance with water quality and NPDES requirements arising under the federal Clean Water Act and California’s Porter­Cologne Water Quality Act. This includes extensive experience with storm water permit requirements, and achieving successful, and creative, resolutions to Clean Water Act citizen suit claims, including in several instances prior to the filing of a lawsuit.

Pete has litigated in federal and state courts for over twenty years, including the successful prosecution of numerous CERCLA cost recovery actions, and defense of dozens of CERCLA, property damage, toxic tort and citizen suits. See, e.g., San GabrielValley Water Co. v. Aerojet General Corp., 606 F.3d 1142 (9th Cir. 2010); Carson Harbor Village, Ltd. v. Unocal Corporation, 433 F. 3d 1260 (9th Cir. 2006); Carson Harbor Village, Ltd. v. Unocal Corporation, 287 F. Supp. 2d. 1118 (C.D.Cal. 2005).

Pete is an Executive Committee member of the California Lawyers Association Environmental Law Section, and 2018 Co-Chair of the Yosemite Conference, nationally recognized as the largest and most prestigious gathering of California’s leaders in environmental, land use and natural resources law. He served as the 2014-15 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 serving on the Board of Trustees for his daughters’ school.
