Why are the agencies placing a repository at East Mission Flats?
The agencies are cleaning up properties as part of a Superfund project to protect human health and the environment. Part of the cleanup involves disposing of contaminated materials, mostly from cleanup of residents’ yards and community areas. Those materials need a secure place to go. Repositories contain contaminated materials safely, which reduces exposures for people and animals. EPA and DEQ searched for other sites for the repository, but at this time East Mission Flats is the most viable location in the lower Basin. Surveys reveal the area where the repository will be placed has at least three feet of contaminated soils. No clean land will be used for this repository.
