Catherine specializes in California and federal environmental law. After decades of experience with a broad range of environmental compliance, administrative, litigation, and enforcement matters, Catherine has focused her practice at EGC on remediation projects, transactions and development projects, and product stewardship and Proposition 65.
Catherine represents a broad range of clients and industries, including manufacturing facilities, the maritime industry, food and beverages, healthcare products, and leaders in the commercial real estate and multi-family housing industry. She has represented a publicly-traded REIT in the multi-family homes industry for over twenty years and represented several of her other current clients for over a decade or more.
Catherine has served either as lead counsel or co-counsel in several major cases, including citizens’ suits claims (Prop 65, stormwater), CERCLA cost recovery claims, and claims for property damage associated with subsurface contamination and soil vapor intrusion.
At EGC, she handled the landmark case, EHA v. Sream, Inc., (September 26, 2022, certified for publication) in which the appellate court affirmed the trial court decision (also handled by EGC) in favor of EGC's client, Sream, Inc., holding that only direct exposures require warnings under Proposition 65. Catherine was lead attorney for another successful landmark case, U.S. v. Chapman, 146 F.3d 1166, 1169 (9th Cir. 1998) (establishing a new test for U.S. EPA’s recovery of its litigation fees in a CERCLA cost-recovery action) and she was lead co-counsel for SF Baykeeper v. Levin Enterprises, (N.D. CA, 2013) (first decision to affirm the scope of stormwater permit requirements applicable to the transportation industry).
Before establishing EGC PC, Catherine co-founded the law partnership of EGC LLP, served as a partner at Hanson Bridgett LLP in San Francisco for seven years, and a partner at Wendel Rosen Black & Dean LLP in Oakland for thirteen years. Catherine started her environmental practice at Wilson Sonsini Goodrich & Rosati in Palo Alto. Before practicing law, she served as a consultant to ICF, Inc., providing support to the U.S. EPA in development of some of the first environmental regulations under certain provisions of CERCLA and RCRA.
