Areas of Focus

Overview

Stacey brings 25 years of experience in regulatory compliance, civil and criminal enforcement, and policymaking to help guide clients through compliance issues, especially those involving environmental and public health and safety regulations. Stacey draws on her years of experience as a prosecutor, regulator, and litigator to navigate compliance challenges, including government-led investigations and unexpected crises. She also leverages her strong relationships across local, state, and federal agencies, in particular in California, as well as her experience representing the United States, State of California, U.S. Environmental Protection Agency, industry, NGOs, and community stakeholders to help improve outcomes and minimize risk and liabilities both before and after issues develop. 

Before joining Crowell & Moring, Stacey served as the deputy assistant administrator at the U.S. EPA, where she helped lead the 2,800-person Office of Enforcement and Compliance Assurance. There, Stacey engaged in numerous elevated or high-profile enforcement actions and participated in rulemaking, policy, and legal guidance. She helped implement EPA’s goal of addressing climate change and PFAS, and helped revitalize the agency’s enforcement and compliance programs throughout the country. A former federal and state prosecutor, Stacey has prosecuted some of the largest environmental cases (including some of the largest U.S. environmental disasters) under the Clean Air Act, Clean Water Act, and federal hazardous waste laws. She has also prosecuted large white-collar cases, with a focus on corporate liability and noncompliance with highly technical regulations. She has been awarded California Lawyer Attorney of the Year; Top 100 Lawyers in California, and the Attorney General’s Distinguished Service Award. 

Given the breadth of her experience, Stacey can provide deep insights into the needs, concerns, and goals of all parties involved in compliance, enforcement, and incident response.
