Chico Municipal Airport Groundwater Remediation Project
NOD - Notice of Determination
Present Land Use
The Butte County General Plan has zoned the existing Chico Municipal Airport property site for light manufacturing and commercial use. The proposed groundwater remediation activities are consistent with the current land use of the property
The proposed project under consideration by the Department of Toxic Substances Control (DTSC) is the approval and implementation of a Remedial Action Plan (RAP). The proposed remedial action consists of the extraction and treatment of contaminated groundwater by carbon absorption to levels below those specified in the State Water Resources Control Board's Resolution 92-49 (i.e. background or non detect). The primary groundwater contaminant at the site is Trichloroethene (TCE), which would be extracted and treated from two Site locations; the existing groundwater extraction well in the center of the plume, and a new groundwater extraction well to be installed at the southwestern (downgradient) end of the plum. The project also includes the installation of six new groundwater monitoring wells further downgradient to monitor plume migration. The intent of the proposed removal action is to capture the higher contaminant concentrations in the mid-plume prior to downward migration.
