UST Mar2014For nearly 30 years, Geotechnology has been involved in underground storage tank (UST) closure services, leaking USTBased Corrective Action (MRBCA) regulation and guidance document that replaces the 2004 guidance document. Geotechnology can help guide you through the new process. If you have a site already in the MDNR Tanks program, we can help you decide if changing to the new regulation would benefit you and your property.
