Portola, California
At the request of PSREC, 7Q10 conducted an investigation of the geographic extent of possible wetland areas or other types of waters of the United States subject to U.S. Army Corps of Engineers (Corps) regulation under the Clean Water Act that could be located within the approximately four-mile corridor of the project area. A jurisdictional delineation report was prepared by 7Q10, submitted to and verified by the Corps. The underground electrical circuit project crossed two large meadow wetland habitats and six intermittent/ephemeral channels. 7Q10 prepared and obtained the necessary Corps permit and California Regional Water Quality Control Board water quality certification to allow for these temporary impacts. In addition, 7Q10 prepared a Storm Water Pollution Prevention Plan as required by the National Pollution Discharge Elimination System General Permit for construction related activities.
