WRENSHALL NORTH BASIN

Wrenshall North Basin - Wrenshall, MN

Belair was contracted to dredge contaminated sediments and soils. Slopes were up to 45 feet above the bottom of the excavation, and soils were stabilized with Portland Cement prior to loading into Off- Road Trucks. Soils were transported to a staging area and reloaded into On-Road trucks for disposal at subtitle-D landfill. Several pipeline crossings were engineered, constructed and maintained to allow normal facility operations. The project included treatment of impacted waters and storm-water management. Belair provided an engineered slope evaluation for compliance with safety regulations along with several Job Hazard Analyses and a Site Health and Safety Plan.
