"He has amassed an incredible knowledge of the chemistry area and has an excellent manner when working with government agencies — he always knows what the best path forward will be."


In the 1980s, Ken Kastner, as the Assistant General Counsel of the Chemical Manufacturers Association (currently the American Chemistry Council), developed and advocated the positions of the chemical industry during the key years when the major hazardous waste programs under the Resource Conservation and Recovery Act (RCRA) were being adopted by the U.S. Environmental Protection Agency (EPA) and challenged in court.

Ken uses this experience to counsel clients on their hazardous waste regulatory requirements, defend them in enforcement actions, represent them as they investigate and remediate contaminated sites, negotiate and appeal their permits, and advocate their positions in rulemakings, litigation, and legislation. As national RCRA counsel to several manufacturers of chemicals and allied products, Ken's practice involves facilities in all of the states and EPA regions.

With 35 years of experience in transportation law, Ken also represents clients on U.S. Department of Transportation (DOT regulation of the transportation of hazardous materials, and drafts and negotiates contracts between shippers and carriers.

A regular trainer and instructor, Ken chairs national seminars on RCRA corrective action and advanced RCRA topics. He has been identified as an outstanding environmental lawyer including in Chambers USA, which writes, "One source describes Ken as 'the most sophisticated RCRA expert that I have ever come across.' Another says: 'He has amassed an incredible knowledge of the chemistry area and has an excellent manner when working with government agencies – he always knows what the best path forward will be.'"
