Environmental Law

Guiding clients through the legal minefield of environmental regulation.

Environmental regulations have created a legal minefield. One misstep may have drastic consequences, as environmental violations do not necessarily require intent or even negligence for liability to attach. Environmental problems often overlap with other legal issues, such as corporate transactions or property transfers. 

Our attorneys have a range of experience from both the private and public sectors addressing land, air, and water rights and liabilities. We represent a wide range of clients in environmental litigation, counseling, and regulatory compliance, from Fortune 500 companies to small businesses and individuals.

Additionally, for decades, Heyl Royster has defended businesses in personal injury and property damage actions, including cases involving benzene, BTEX compounds, vinyl chloride, nickel/chrome, diacetyl, asbestos, welding rod exposures, coal exposure, and silica. Our attorneys have negotiated Highway Authority Agreements in the public sector and defended claims before the Illinois Environmental Protection Agency. We have negotiated Compliance Commitment Agreements, obtained No Further Remediation letters, and worked with the U.S. and Illinois EPA on aspects of property redevelopment. With offices throughout the Midwest, we respond quickly and coordinate our efforts for cost-effective results.
