State officials are accepting comments on the environmental impacts of a project proposed by 3M Corp. to collect surface water upstream of a dump in Oakdale in order to reduce polyfluoroalkyl substances (PFAS) in stormwater discharge from the site.
The Abresch Disposal Site is the largest of three former disposal locations that comprise the Oakdale Disposal Site, a state and federal Superfund site.
3M is working with the Minnesota Pollution Control Agency to remediate soil and groundwater at the site. The project is proposed to further reduce PFAS impacts to stormwater discharge from the site, according to an environmental review of the project.
The proposed project would collect surface water upstream of the site and divert it to a three-acre flood-retention basin, where water would then be reintroduced into the natural flow of the watershed, according to the environmental assessment worksheet.
A three-quarter-mile conveyance pipe would bypass the Abresch Disposal Site, thus bypassing PFAS detected within the site, according to the EAW. “This would reduce the discharge of PFAS in surface water and improve downstream surface water quality in the Twin Cities east metropolitan area,” the EAW states.
The Minnesota Department of Natural Resources is accepting comments until 4:30 p.m. June 26 on the EAW.
A copy of the EAW is available on the project page of the DNR website; a print copy may be requested by calling 651-259-5522.
The EAW is also available for public review at the Oakdale Library, the DNR Library and the Minneapolis Central Library.
