Nancy Wilms is an environmental litigation partner with more than 30 years of experience in complex litigation matters. She represents major generators and de minimis PRPs nationwide in multiparty CERCLA and private cost recovery actions both with and without regulatory enforcement components. She also has a breadth of common counsel experience and defends clients against citizen’s suits brought under the Resource Conservation and Recovery Act (RCRA) and the Clean Water Act (CWA). In recent years, she has developed a particular focus on representing municipal clients in high-profile wastewater collection and treatment system litigation against coalitions of federal and state regulators and non-governmental organizations. In addition, Nancy has extensive experience handling groundwater contamination cases brought by municipalities and water districts seeking damages and injunctive relief under both federal and state law theories.
Nancy’s work encompasses all phases of environmental litigation and administrative actions, including negotiation of settlement agreements, organization and management of PRP groups, work with consultants on site evaluations and remedial alternatives, and development of strategic plans to implement the client’s goals. She has extensive experience successfully negotiating consent decrees, remedial designs and related documents with federal and state agencies. Her practice also includes agency enforcement actions and environmental audits.
Nancy’s skill at working collaboratively with multiple defendants while maintaining the client’s strategic direction leads to cost-effective resolution of complex cases. Nancy understands that the client’s goals for the outcome of each matter are paramount and strives to minimize the business disruption that too often comes with high-stakes litigation.
In 2012, Nancy was appointed to the City of South Pasadena’s Natural Resources and Environmental Commission and re-appointed for a second term in 2015.
Prior to joining Edgcomb Law Group, Nancy worked at the Los Angeles offices of two multi-national law firms for a combined 30 years. She joined Edgcomb Law Group in 2013, as one of the first partners in the Southern California office.
