Eagle Lake Wastewater Facility

Susanville, California

The Eagle Lake Wastewater Ponds (ELWP) Facility is located on the Eagle Lake Ranger District in Lassen National Forest. There are four sewage ponds at the Eagle Lake Wastewater Facility. These ponds are filled with wastewater which then evaporates from the ponds. The ELWP are used to treat all the Forest’s sewage from the Eagle Lake Campgrounds and Marina. In the event that a section of the lining fails and cannot be repaired, seepage from the ponds may pose a threat to the health and safety of the public. The purpose of the Wetlands Delineation Study for ELWP Facility is to identify the wetland area that may be impacted by the proposed construction of a new 5 to 6 acre wastewater evaporation pond at the facility. Foothill Associates conducted a wetland delineation study of a 20 acre site.  The report included a map showing limits of wetlands area and a description of the wetland, including the type of wetland.  The wetland delineation study was prepared to support National Environmental Policy Act (NEPA) documentation, acquiring a 404 permit for constructing a new 5 to 6 acre wastewater evaporation pond, a 2 to 3 acre borrow pit and replacing the lining for the existing wastewater ponds at the facility, and obtaining a permit from Lahontan Regional Water Quality Control Board.
