Recently, the Department of Toxic Substances Control released a carefully worded letter to the Oak Creek developers KB Homes Sept 11, 2019 .
While ENU fully supports the permanent prohibition on future uses of groundwater at the site (for obvious reasons), DTSC makes a very interestingly worded statement in this Removal Completion Report letter.- bold
added for emphasis.
that releases from the Chatham Yard do not appear to represent an environmental
concern to the Site of future occupants, as contaminate concentrations appear
to be naturally attenuating.”
future when the natural attenuation is complete there won’t be an environmental
concern. Our concern is that DTSC’s opinion is based on future conditions, not current
conditions; ie, future occupants, attenuating.
of natural attenuation will be complete so that when the future occupants move
in they will be protected.
occupancy permits the developer will need to do additional testing to
demonstrate that the process of natural attenuation is complete?
