The Secretary-Treasurer position is elected to a two-year term by a majority vote of the Association’s State representatives.
As the Director for the New Jersey Department of Environmental Protection’s (NJ DEP) Division of Remediation Management, Ken is responsible for all site remediation activities in New Jersey, including those performed by Licensed Site Remediation Professionals on behalf of responsible parties and brownfield developers; CERCLA; RCRA corrective action; federal facilities and NJDEP-funded response actions.
Ken’s involvement with ASTSWMO began in the late 1980s when he was invited to participate on the CERCLA Site Evaluation Focus Group, which he later chaired for several years before serving as Chair of the CERCLA & Brownfields Subcommittee. This October he concludes two consecutive three-year terms as Region 2 Representative on the Board of Directors and member of the Finance Committee. He also serves on the ad-hoc Poly- and Perfluoroalkyl Substances (PFAS) Workgroup.
Ken is a 1981 graduate of Seton Hall University with a B.S. in Biology. He began his career with the New Jersey Department of Environmental Protection in 1985 as a field investigator, evaluating contaminated sites for inclusion on the National Priorities List. He has served in various managerial roles within the NJDEP, including Brownfield Administrator, where he implemented a number of innovative approaches for brownfields remediation and redevelopment, including New Jersey’s Brownfield Development Area (BDA) initiative.
Most recently, Ken was instrumental in the New Jersey’s transition from a “traditional” remediation oversight program to one employing Licensed Site Remediation Professionals, or LSRPs, who are retained by remediating parties to perform remediation activities in accordance with NJDEP statutes, regulations and guidance, but without specific direction from, or the day-to-day involvement of, NJDEP regulators.
Ken is a life-long resident of New Jersey, currently residing in Toms River, New Jersey, with his wife, Karen, who manages NJDEP’s Office of Community Relations. Together they enjoy sailing, fishing and crabbing, and most other water-related activities. They are the proud parents of two amazing young men, Alex, an Ensign in the US Coast Guard, and Adam, currently employed with the NJDEP as a GIS Technician.
