Board authorizes Triple Point Engineering landfill compliance services; engineers warn post-closure care often exceeds 30 years

Tony Roberts of Triple Point Engineering answered commissioners’ questions about the closed county landfill and the status of opening cell five. Roberts said the regulatory post-closure period is a minimum of 30 years and that unlined, older landfills frequently require monitoring past that term; requests to end post-closure care early are rarely granted though decreasing groundwater contamination concentrations can eventually support a request.
