The U.S. Environmental Protection Agency has deleted a parcel of land at the Mystery Bridge/U.S.
This parcel owned by Kinder Morgan, Inc., was removed from the priorities list after the completion of soil and groundwater cleanup actions, according to the news release.
In 1990, the EPA added the Mystery Bridge site to the national priorities list after the discovery of extensive soil and groundwater contamination along U.S. Highway 20 east of Evansville.
The national priorities listing came four years after Brookhurst residents complained of poor air and water quality in the area.
The Wyoming Department of Environmental Quality, the Natrona County Health Department, and the EPA’s Office of Drinking Water began investigating the site, according to the EPA’s Record of Decision about the site.
After receiving no adverse site-specific comments, the parcel was deleted from the national priorities list on Aug. 29, according to the news release.
The deletion of a site or portion of a site from the priorities list does not preclude the EPA from taking future actions at the site.
The next review report is due September 2019.
The EPA Mystery Bridge site website contains further information about the site and provides documents supporting the partial deletion.
