Biography

Hilary supports clients in the rapidly changing sustainability, renewable energy, and environmental justice landscapes.

Her commitment to environmental protection is longstanding — while in high school, she took home 95-gallon trash bags filled with her peers’ empty plastic bottles and cans for months until her school established its own recycling program. She brings that same proactive, solutions-oriented mindset to her legal career, where she is passionate about helping clients effectively and efficiently comply with environmental law and regulations.

Hilary’s robust regulatory practice includes helping clients address issues arising under the Clean Water Act, the Resource Conservation and Recovery Act (RCRA), and federal, state, and local laws related to the development, operation, and support of renewable energy projects, including solar, offshore wind, and other alternative energy sources, such as nuclear. She routinely advises renewable energy developer clients on permitting, transactional, and litigation challenges.

Hilary works on sustainability issues with the wastewater industry, collaborating closely with companies on the beneficial reuse of biosolids and residuals. Hilary regularly counsels on issues surrounding compliance with federal and state biosolids and residuals recycling regulations. She helps clients address overly restrictive state and local land application regulations. She recently led a team that successfully resolved a federal Clean Water Act enforcement matter through negotiations with regulators to achieve a favorable outcome and effective compliance frameworks focused on biosolids management and nutrient controls.

Hilary also advises clients on how to integrate environmental justice considerations into every aspect of their operations as issues arise and on a more systemic basis. She serves as Co-Chair of the Environmental Justice practice group, and regularly writes and presents on state and federal environmental justice issues. She oversees B&D’s environmental justice-focused podcast, Groundtruth, produced in partnership with the Environmental Law Institute.

Hilary’s litigation experience also includes nationwide products liability matters involving alleged groundwater contamination from fuel additives. She has supported fact and expert discovery and complex motions practice in cases brought by multiple state governments seeking significant damages.
