Document Description
The Department of Water Resources Technical Support Services Program proposes to drill and install one single-completion monitoring well in the Indio Subbasin in cooperation with the landowner, Coachella Valley Water District. The purpose of the well is to fill data gaps within the groundwater monitoring network and provide hydrogeologic data under the Sustainable Groundwater Management Act.
Drilling will consist of initially setting a 16-inch by 50-foot permanent conductor casing to advance a 10-inch-diameter boring. The monitoring well will be drilled up to 175 feet below ground surface (bgs) in the shallow aquifer zone. Geophysical surveys will be performed within the boring including: natural gamma ray; spontaneous potential; short-normal, long-normal and point electrical resistivity logs; vertical deviation; and a caliper survey. After the geophysical logs have been completed and formation samples evaluated, DWR will construct a target well screen of 50-150 feet bgs and seal for the location. All drill cuttings will be stockpiled on-site with the potential for re-use. Fluid and drill cuttings are expected to be nonhazardous and will be sampled and analyzed for constituents for concern prior to disposal.

Reasons for Exemption
The proposed Project is categorically exempt under Class 6, Section 15306 because it consists of basic data collection and resource evaluation activities that do not result in a significant impact to an environmental resource. A preconstruction survey was conducted which revealed no sensitive resources on the proposed Project site. Overall, no significant impacts are anticipated for biological, air quality, noise, visual, water quality, land surface, or historic and archaeological resources.
