Steve Humphreys is special counsel in the firm's Parsippany office, where he concentrates in all aspects of environmental law and related counseling of businesses. He also assists business clients in such emerging fields as environmental sustainability business auditing, renewable energy development and energy conservation infrastructure. Other areas of emphasis in Mr. Humphreys' practice include litigation and regulatory compliance counseling in matters arising under CERCLA, the federal Resource Conservation and Recovery Act (RCRA), Clean Air Act, Clean Water Act, and various state and local environmental laws, as well as environmental aspects of business transactions.


Mr. Humphreys represents purchasers and sellers of contaminated or potentially contaminated and “brownfields” properties in transactions involving single and multiple properties, both in the United States and abroad, and he represents lenders and borrowers in commercial loan transactions and loan workouts. He has particular experience in developing strategies for the identification, management and allocation of environmental risk in business transactions, including the use of environmental insurance products, guaranteed remediation contracts and governmental liability protections to offset risk.


Mr. Humphreys also represents owners of real property seeking to manage environmental liabilities through voluntary cleanup programs and property transfer laws such as the New Jersey Industrial Site Recovery Act. He has experience retaining and managing environmental engineering firms, including response action contractors, for projects involving the investigation and remediation of contaminated property.


Another aspect of Mr. Humphreys' practice involves the representation of clients in prosecuting and defending claims under the federal Superfund law (CERCLA) and comparable state statutes for recovery of costs associated with cleaning up environmental contamination at various types of industrial and commercial properties. Mr. Humphreys also has represented corporate clients regarding regulatory enforcement actions and/or obligations arising under CERCLA, RCRA, the Clean Air Act, Clean Water Act, federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), and various state and local environmental laws. In addition, Mr. Humphreys has represented corporate clients and property owners in the prosecution of several insurance recovery cases, leading to the recovery of millions of dollars in proceeds under insurance policies for environmental-related damages and losses.


Mr. Humphreys' practice also includes counseling clients in a wide range of compliance issues arising under federal and state environmental laws, primarily with regard to hazardous waste regulation and water and air permitting matters. He has participated in the development of significant federal rulemakings under CERCLA and RCRA through the submission of comments on behalf of affected parties.


Mr. Humphreys has written numerous articles on various environmental law issues, including environmental considerations in real estate and corporate transactions, criminal enforcement of environmental laws and hazardous waste cleanup cost recovery. He also is a frequent speaker at conferences and seminars on environmental law topics. His recent speaking engagements have included such topics as "Water Rights and Resource Management," "Buying and Selling Contaminated Properties" and "New York's Brownfields Cleanup Program."
