Mary Katherine Stukes is co-head of the firm’s Environmental practice. She advises clients on environmental issues involved in all types of business transactions, as well as regulatory compliance issues and environmental litigation.  Ranked in Chambers Partners USA since 2017, clients describe her as a “zealous but practical advocate.”


Mary Katherine regularly leads real estate developers, governmental entities, and non-profit corporations through the process of obtaining Brownfields agreements for redevelopment of contaminated properties. She negotiates agreements with environmental agencies and counsels clients on eligibility, assessment, tax benefits, and effective structuring of associated real estate and financing transactions. Her projects include agreements for the development of various multifamily residential, hotel, office, governmental, hospitality, community development and industrial projects, including the transformation of former landfills, drycleaners, and gas stations into high-density developments in the urban cores of the major cities in the Carolinas, a minor league baseball stadium, a free-standing emergency department, a police station, a large-scale youth soccer complex, a national craft brewery, and other adaptive reuse projects.

In addition, Mary Katherine helps manufacturers, real estate developers, lenders, renewable energy companies, automotive dealerships, local governments, and other clients find creative solutions in real estate, financing, and corporate transactions involving environmental risk. She routinely negotiates agreements to allocate environmental responsibility and risk between multiple parties and also provides support in due diligence reviews and assistance with permit transfers on such transactions.

She also counsels manufacturers, lenders, and other corporate clients on a broad range of environmental risk and compliance issues. Her work in this area includes release investigation and remediation oversight, incident closure, environmental permitting, audits, reporting, and self-disclosure, responses to CERCLA (Superfund) Section 104 information requests, participation in CERCLA potentially responsible party (PRP) negotiations, appeals of agency orders, defense of notices of violation and enforcement actions, waste and materials handling and disposal practices, stormwater and wastewater management issues, state and federal wetlands and other natural resource issues, and other aspects of regulatory compliance across a variety of state and federal regulatory programs.

Mary Katherine is an experienced litigator in federal, state, and administrative courts. She has represented clients in disputes over contamination, asbestos-containing materials, underground storage tanks, landfills, water quality, and other environmental issues.

“She’s practical, knows the substance very well, and could get down to the issues quickly,” one of Mary Katherine’s clients told Chambers USA, which develops rankings using in-depth interviews and objective research. Another client praised her ability to navigate what can be a complex regulatory landscape: “Mary Katherine helped break down the walls and get the process moving.”
