Kenneth Yass, P.E., CHMM

Ken Yass is a Principal Environmental Engineer based in Wisconsin with more than 25 years of experience focused on environmental compliance services for a wide range of industrial clients.


Ken's focus is on understanding and ultimately helping to own his client's environmental compliance challenges and providing cost-effective solutions that fit within the client's business objectives.  He has worked with manufacturers of friction material, agricultural tractors, valves, electrical transformers, chemicals, industrial rolling equipment, ink, bathroom partitions, truck dock systems and iron, steel and aluminum castings.  He has also worked with hospitals, municipal entities, airline maintenance hangars, logistics companies, malting facilities and metal sintering operations.  Ken is a subject matter expert in air permitting and compliance, Spill Prevention Control and Countermeasures (SPCC) Planning, Emergency Planning and Community Right-to-Know Act (EPCRA) compliance and reporting and Department of Homeland Security (DHS) compliance.  He also has substantial experience with storm water, hazardous waste and industrial wastewater management.  Ken has performed environmental services in 20 states.  He worked as an environmental consultant for 22 years prior to being responsible for environmental and DHS compliance at a national chemical manufacturing and distribution company for three years prior to coming back to consulting.

Ken has led responses to Notices and Findings of Violations (NOVs, FOVs) on behalf of chemical manufacturing facilities, working both with internal and external legal counsels, and negotiating settlement agreements with both the state and federal environmental agencies.  He can take the complex and make it concisely understandable, including the updating of an SPCC Plan for an animal fat processing facility with over 100 storage tanks and over 3,500,000 gallons of oil storage capacity.  Ken has often significantly streamlined the environmental management practices of several different types of facilities and entities.  He has provided litigation support for several law firms on several environmental compliance topics.

To advance the state of the practice, Ken focus's on listening to the client's needs and challenges, understanding how these put strain on the company, and creatively identifies solutions that both fit within the facility's current practices and that are cost-effective.  He speaks periodically, for example, to groups of environmental practitioners that are seeking CHMM certification at a 3-day review and preparation course.  Ken's clients find him organized, efficient, available and easy to work with.
