Ken Gray joined Pierce Atwood's Environmental Group in 1987 after practicing with the U.S. Environmental Protection Agency's Office of General Counsel in Washington, D.C. Ken has practiced environmental law since his graduation from law school in 1979.

Ken concentrates on counseling and enforcement issues related to hazardous substance and hazardous waste management, cleanup, and liability, including toxic tort matters; chemical safety requirements under a variety of laws including the Occupational Safety and Health Act; product regulation including toxic substance manufacturing and processing; emergency planning, response, and community right-to-know requirements; groundwater and drinking water regulation; and transactional matters related to environmental concerns. Ken is co-author of the Maine PFAS Tracker, which provides the latest news and updates on Maine standards and proposed actions on PFAS.

At the EPA, Ken advised the Agency on matters arising under the Resource Conservation and Recovery Act (the hazardous waste law); Safe Drinking Water Act; Comprehensive Environmental Response Compensation, and Liability Act ("Superfund"); Clean Water Act; and the Toxic Substances Control Act. He received two bronze medals for his work.

Much of Ken's practice involves addressing and resolving environmental issues in a cost-effective manner before they become environmental problems. Ken has counseled manufacturers in a wide variety of businesses, Superfund PRP groups, water companies and districts, municipalities, trade associations, and homeowners' associations.

Ken has advised business and real estate owners and purchasers, commercial enterprises of all types, banks and lenders, and drinking water suppliers. Because the purchase and sale of businesses and property must address the possibility of environmental contamination, Ken has been involved in numerous transactions of virtually all sizes. Ken and Pierce Atwood were selected as counsel for the Portland, Maine Brownfields Project, one of the EPA's flagship projects.  He was instrumental in Maine's adoption of the Uniform Environmental Covenants Act, and has spoken nationally on the topic.
