Michael Minch is a Senior Principal Geotechnical Engineer based in California with more than 25 years of experience focused on the design, permitting, and construction phases of waste containment facilities and maintenance of their long-term integrity throughout the western United States.
Effective management of municipal solid waste has proven to be a challenge in every part of the globe. The Kekaha Sanitary Landfill is the only operating municipal solid waste landfill on the island of Kaua’i, and Mike was the lead engineer during the construction of its waste cell expansion and a new leachate pond. He also managed the clean-closure of the facility's original leachate pond and reconfiguration of the original site leachate collection and conveyance system.
Clients, primarily commercial waste disposal facilities and regional municipal solid waste disposal agencies, frequently rely upon Mike for his consistent, reliable, buildable, and cost-efficient designs to solve their often complex geotechnical problems. He specializes in the design and construction of containment facilities for solid and liquid waste and has extensive experience with CQA for the installation of geosynthetic and clay liners.
Mike was the CQA Engineer for the construction of 40-ft high, a 2300-ft long mechanically stabilized earth (MSE) berm in Western Oregon built along the western side of the existing landfill to increase the permitted site capacity without the need for a lateral expansion. The project included the construction of a composite liner system on the inside face of the berm for waste containment, moving the majority of the site entrance facilities, and the re-configuration of a large portion of the site’s landfill gas collection infrastructure. And, he was the lead engineer for multiple cells at a waste containment facility in Maricopa County, Arizona built over the past 15 years where he managed the cell design, laboratory testing, and preparation of construction drawings, technical specifications, CQA manuals, reports, and CQA activities.
