NOTE: Shortened Review/Addendum Willow Creek Wastewater Treatment Plant Modification: The existing Willow Creek WWTP will terminate wastewater treatment operations and be converted for use as a primary flow equalization facility. Existing wastewater treatment ponds will be lined and converted to wastewater storage ponds. All existing wastewater flows will be directed to the existing Grass Valley WWTP through an existing intertie pipeline. Grass Valley WWTP System Upgrades: The existing Grass Valley WWTP will be upgraded from a 2.5 MGD capacity wastewater treatment facility to 3.75 MGD capacity wastewater treatment facility in order to accommodate the existing flows from both the Willow Creek and Grass Valley WWTP. The proposed expansion will include the addition of a primary clarifier, a trickling filter, a secondary clarifier.
