David G. Mandelbaum
David G. Mandelbaum co-chairs the firm's national environmental practice. He often represents clients faced with problems under the environmental laws that have no conventional solution, or for which the conventional solution would yield an unacceptable result. While he regularly represents clients in lawsuits, he does not restrict his practice to litigation and has helped clients achieve satisfactory outcomes through regulatory negotiation or private transactions. As highlighted below, Mr. Mandelbaum has represented clients in some of the Superfund – particularly contaminated sediment and natural resource damage – matters that the government considers its most significant. He represents natural gas exploration and production companies, midstream providers, and landowner coalitions in connection with development of the Marcellus Shale and other natural gas resources. He regularly handles permit appeals and citizen suits under the water pollution, air pollution, and solid waste laws. He has represented clients in litigation under the National Environmental Policy Act (NEPA) and several disputes among private parties following failed or unsatisfactory transactions. Mr. Mandelbaum was one of the original appointments to the Pennsylvania Statewide Water Resources Committee, which is responsible for the State Water Plan. He has advised clients in water supply matters, and has appeared before water supply agencies such as the Delaware River Basin Commission. Mr. Mandelbaum teaches Superfund, Climate Change, and Oil and Gas Law in rotation at the Temple Law School. He has taught Land Use Law and Administration to graduate planning students, and he is a regular writer and speaker.
