With a strong background in litigation challenging or defending federal regulations, advising on regulatory compliance, internal investigations, and defense against government investigations and enforcement actions, Corinne provides clients with practical advice on how to prepare for and shape new regulations, how to distill and effectively communicate legal requirements within an organization, and how to manage communications with regulators. She has worked with clients across the energy industry and has been recognized by both the National Law Journal and Law360 as a “rising star”.
Corinne draws on wide experience at the U.S. Department of Justice where she most recently served as Counsel and Chief of Staff in the Environment and Natural Resources Division of the U.S. Department of Justice, where she assisted in managing a 600-person division that included 400 lawyers. In this role she helped manage the Division’s civil and criminal litigation arising under more than 150 environmental and natural resources laws. She also worked closely with the General Counsel’s Offices for multiple federal agencies, including the EPA, Departments of Interior, Defense, Energy, Commerce, and Agriculture, as well as the White House and Counsel on Environmental Quality to advise high-ranking officials on policy and litigation risks associated with the environmental and natural resource laws and regulations. She also served as Senior Counsel in the Office of the Associate Attorney General, which oversees all civil litigation on behalf of the United States, and as Counselor in the Office of the Attorney General. Her roles in government have given her a unique perspective into the decision-making processes in the federal government.
Corinne has personally argued five cases in four U.S. Courts of Appeals, argued in multiple district courts, and served as the lead or co-lead counsel in district court litigation defending agency regulations, approvals, and permits related to energy projects.
In the private sector, Corinne counsels clients on environmental compliance across a variety of industries, including the energy and mining sectors, water utilities, and trade groups. In the transactional context, she assists in the drafting and negotiating of the environmental terms in purchase and sale agreements, lease agreements, credit agreements, and disclosures for debt and equity offerings and public filings. Corinne also helps clients understand how their environmental and climate disclosures will interact with existing and forthcoming regulatory requirements and how to limit legal liability risks related to those disclosures. She also advises clients on preparing for regulatory changes, including by drafting comments on rules proposed by federal agencies such as EPA, the SEC, FERC, and Interior. She also advises on issues related to emerging contaminants and is a member of the firm’s PFAS task force.
“I have worked with a wide range of attorneys over my long career in the energy industry, and Corinne stands out among them. Time and again, her counsel and judgment have proven invaluable and unerring. I trust her to handle the most important and complex issues for our operations. In short, Corinne is an established star in the environmental bar, and I hold her in the highest regard. Indeed, she is the finest environmental attorney I have had the pleasure of working with over my 22 years in the energy industry (client quote, National Law Journal, 2024).”
“We turned to Corinne in these and other cases because of her ability to marry tenacity to diplomacy, which is critical to an organization like ours that has a well-deserved reputation for challenging federal regulations, when appropriate, in a reasonable, measured manner that never loses sight of [our] deep concern for public health and the environment. . . . There are few environmental lawyers at any level who combine Corinne’s skill and emotional intelligence (client quote, National Law Journal, 2024).”
