News & Events

Tom is a partner with Manko, Gold, Katcher & Fox, LLP.  He concentrates his practice on environmental transactional matters, regulatory counseling, and environmental litigation.  He is also a member of the firm’s air practice group.  Tom handles a wide range of environmental matters, including brownfield redevelopment projects and transactional-related environmental due diligence.  He represents entities in multi-party state and federal litigation involving cost recovery and indemnity claims, as well as contribution claims for contamination and remediation conducted under CERCLA, RCRA, and state laws. 

Tom represents private equity investors, developers, manufacturers, and institutions in transactions involving current and former industrial sites in which environmental risks and liabilities were critical to the structure of the transaction and investment analysis.  In connection with those representations, Tom negotiates the environmental aspects of transactional agreements, regulatory consent agreements, and prospective purchaser agreements.  He has negotiated technically complex consent decrees with the U.S. Department of Justice, the U.S. Environmental Protection Agency, and state agencies, and has conducted extensive internal environmental audits.

Tom came to the firm from an AmLaw 100 firm in Philadelphia, where he was an attorney in the environmental and energy practice group.  In that role, he represented and counseled a broad range of clients in regulatory and transactional matters and litigated cases before state and federal courts, the Pennsylvania Environmental Hearing Board, and the Pennsylvania Public Utility Commission.  Prior to that, Tom served as an assistant counsel to the Pennsylvania Environmental Hearing Board.

In law school, Tom was a law clerk for the U.S. Environmental Protection Agency, a legal intern for the Pennsylvania Department of Environmental Protection, and a judicial clerk for the Honorable Thomas J. Reuter of the U.S. District Court for the Eastern District of Pennsylvania.  He served as president of the Environmental and Energy Law Society, and upon graduation he received Villanova’s Public Interest Fellowship Program Award. 

Tom holds a governor-appointed position as a member of the Environmental Hearing Board Rules Committee.  He also serves as treasurer of the Pennsylvania Bar Association’s Environmental and Energy Law Section and chairs the Section’s Pro Bono Committee.  Tom is also a member of the Delaware Valley Environmental American Inn of Court and serves on its Membership Committee.  In addition, he serves on the Board of the Lower Merion Conservancy and has served as an appointed member of East Bradford Township’s Environmental Advisory Council.

Tom is married to his high school sweetheart, and they have three young children.  Outside of work, Tom enjoys coaching and spending time with his family.

Tom’s representations extend from private individuals through major international corporations, relating to brownfield redevelopment, complex transactions, regulatory compliance counseling, and environmental litigation, including the following matters:

  • Assisting clients in all elements of brownfield redevelopment projects including due diligence, site characterization and remediation, risk management strategies, future use approvals, institutional controls, liability protection; and attainment of governmental cleanup liability protection under the federal Superfund program and under Pennsylvania, New Jersey, and other state brownfield programs;
  • Addressing environmental contamination of soils, surface water, and groundwater, including overseeing consultant work and achieving satisfaction of alternative attainment standards in the most cost-effective and timely manner;
  • Complex transactions for the purchase and sale of businesses and real estate, including contract negotiation, due diligence, permit transfers, securing pre-acquisition environmental liability protections, and preparing institutional controls and environmental covenants;
  • Advising clients on compliance with complex federal and state regulatory requirements;
  • Defending enforcement actions by federal, state, and local agencies, including responding to orders, information requests, penalty assessments, and negotiating settlements;
  • Providing immediate counseling to industrial facilities in response to emergency incidents resulting from the release of regulated constituents to the environment, including coordinating response actions and responding to governmental inquiries;
  • Appealing numerous air quality, water quality, and solid waste permits in response to objectionable conditions, and defending environmental permits against third party challenges;
  • Representing clients before the Pennsylvania Environmental Hearing Board and state and federal administrative agencies and courts; and
  • Superfund litigation involving successor liability, unilateral orders, remedy selection, consent decrees, allocation, and private party liability issues.
