Gregory R. Wall

Counsel

Profile

As a former US Environmental Protection Agency (EPA) senior attorney, Greg uses his deep agency, regulatory and enforcement knowledge to assist clients in solving complex environmental matters, with specialized expertise in CERCLA/Superfund, brownfields, RCRA, FIFRA and TSCA legal issues.

With over 15-years of experience in environmental law, Greg assists clients in regulatory counseling, enforcement defense, litigation, and transactional matters. His experience in both private and public practice, in particular at EPA, provides him the ability to navigate the regulatory process with an informed understanding of government decision-making and strategies for efficiently resolving complex legal and policy issues. He has significant experience related to the acquisition and sale of environmentally-impaired property, conducting voluntary cleanups, and the re-development of brownfield sites, including for renewable energy projects, as well as advising clients on EPA regulations and policies across a diverse client base, including oil & gas, electric utility, chemical, mining and marine transport.

Greg’s extensive practice of CERCLA at the highest levels in the federal government allows him to advise clients, particularly the defense of clients facing government enforcement or private party contribution actions. While at EPA, Greg served as the lead EPA Headquarters attorney on cleanup enforcement cases at Superfund sites with remedies exceeding $1 billion and regularly worked on national matters involving CERCLA. He also authored multiple national guidance documents on CERCLA enforcement and drafted model settlement documents used by EPA nationwide. During his EPA tenure, Greg received numerous EPA and DOJ awards, including for his work on the Administrator’s Superfund Task Force and the development of EPA’s national enforcement response to the US Supreme Court’s landmark decision in Burlington Northern & Santa Fe Railway v. United States.

Greg is an adjunct professor at William & Mary Law School, teaching Environmental Law and the Regulation of Toxic Substances and Hazardous Waste.
