Document Description
Based on groundwater modeling projections by PG&E, extraction at approximately 130 gallons per minute (gpm) from the TW-2 extraction well will be required to provide an inward gradient during month of highest groundwater discharge rates (October 2004). The critical elements for this proposed project are the piping, conveyance of groundwater, construction of temporary treatment facilities, and development of a disposal method for treated water.

Reasons for Exemption
These project activities are necessary to prevent or mitigate an emergency situation wherein the waters of the Colorado River may be impacted with a hazardous constituent, chromium, which is in contaminated groundwater in close proximity to the river. Immediate action is necessary to contain and reverse the flow of groundwater away from the Colorado River. Commencement of the development of additional extraction, treatment, and treated water disposal capacity is urgent to assure that increased pluming rates will be available to respond to impending fluctuations of the Colorado River level.
