DWR proposes to replace the existing structure and install soil sensors at Dudleys hydrometeorlogical station.

Reasons for Exemption
Replacement of the station structure, soil testing, and temporary excavation of a 3'x3'x3' soil pit and shallow trench that would be backfilled upon completion of soil sensor probe installation qualifies for categorical exemptions 15301 (existing facilities), 15304 (minor alterations of land), and 15306 (information collection) because proposed activities would involve negligible expansion of existing use, would not have a significant effect on the environment, and would result in only temporary, minor ground disturbance.
