Michael R. Blumenthal

Of Counsel

3401 Tuttle Road
Suite 200
Cleveland, OH 44122

Michael’s practice focuses on environmental compliance and counseling, enforcement defense, multimedia environmental audits, permitting issues, and environmental litigation between private parties and the government. As a former Ohio Assistant Attorney General, his knowledge is regularly enlisted to craft regulations pertaining to environmental safety.

Michael has worked extensively in the areas of solid and hazardous wastes, petroleum underground storage tanks, NPDES permits, and environmental investigation/remediation. He routinely assists clients with due diligence in business and commercial real estate transactions. This includes representing manufacturers, energy providers, and developers in negotiating environmental, air, water, and hazardous waste permits with state and federal governments. He oversees emergency response and removal actions and develops long-term cleanup agreements with both state and federal governments to bring sites to closure or “No Further Action” (NFA) status. Michael represents clients in multimedia audits, environmental audit privileges, and environmental issues related to real estate transactions, storm water regulations and underground storage tanks.

Michael assists both private and public agency clients with the entire National Environmental Policy Act (NEPA) process, which applies to federal approvals, by guiding them from initial planning, federal permit applications, and entitlements through NEPA noticing, document preparation and circulation, public review, regulatory compliance, and requirements specific to each federal agency involved. He defends lawsuits challenging the environmental impact statements brought by project opponents to challenge the approvals granted upon completion of the environmental reviews process.

He routinely represents developers in site acquisition and redevelopment of brownfield properties, ranging from overseeing environmental due diligence, to developing acceptable cleanup standards with the EPA and OEPA in obtaining site closure letters (NFA’s) and covenants not-to-sue. He also counsels municipalities on obtaining grant money and low-interest loans from state and federal brownfield programs.

Michael routinely prosecutes and defends cost recovery, Citizen Suits, common law, and injunctive relief claims brought under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA/Superfund); the Resource Conservation and Recovery Act (RCRA); the Clean Air Act (CAA) and the Clean Water Act (CWA). He defends environmental enforcement actions, Notices of Violations (NOVs), and Information Requests initiated by the state and federal government for purported violations of U.S. Environmental Protection Agency (EPA), Ohio EPA (OEPA), and Ohio Bureau of Underground Storage Tank Regulations (BUSTR).

Michael is also a member of the White Collar Government Investigation Group, in which he represents clients before the United States Department of Justice and Ohio EPA for environmental crimes related to violations of the CWA, CAA, and RCRA.

Currently, Michael is working with Ohio EPA in rolling out a certification program for water quality professionals for collecting data to assess streams and categorize wetlands, in support of applications for Section 401 Water Quality Certifications and Isolated Wetland Permits. He is actively involved in seeking “common sense” and practical solutions related to emerging contaminants (“forever chemicals”). Michael is participating on a variety of rulemaking committees representing the interests of private industry.

Notably, Michael is a former Ohio Assistant Attorney General in its Environmental Enforcement Section. In that role, his primary responsibility was to enforce state and federal EPA regulations. While with the Attorney General’s Office, Michael also helped launch and develop Ohio’s Underground Storage Tank Program and was one of the principal authors of BUSTR. He also developed eligibility and claim guidelines for Ohio’s Petroleum Underground Storage Tank Release Compensation Board (PUSTRCB) regulations, relating to payment of state funds associated with underground storage tanks. He routinely participates on various OEPA and BUSTR rulemaking committees.

Michael previously served as a founding partner of Waxman Blumenthal in Cleveland. He is a member of the board of trustees of both Stella Maris, Inc. and Fresh Start, Inc., nonprofit corporations focused on providing alcohol and chemical dependency treatment and mental health services to the indigent and homeless.
