Document Description
Addendum is being compiled to address the following issues related to the RP-5 Expansion Offsite Facilities Projects. These projects were not included in the PEIR, and in order to acquire funding to implement these four Offsite Projects, an Addendum has been selected to comply with the California Environmental Quality Act (CEQA). These four projects include:
1. Butterfield Ranch Pump Station (lift station): An existing pump station where two actions will be carried out. Internal to the existing building, the existing pumps will be upsized and the existing Motor Control Center (MCC) will be replaced by a new MCC. The purpose of the modified lift station is to pump wastewater to RP-5 i. There will be no new ground disturbance at the site, just modifications to the building interior. With no new ground disturbance, there is no potential to adversely impact any biological or cultural resources at the project site. In this analysis this facility will be referred to as Site 1.
2. Mountain Avenue Pump Station (lift station): This project will construct a new pump station (lift station) adjacent to Mountain Avenue, across from Bickmore Avenue where it intersects Mountain Avenue at IEUA’s Solids Handling Facility site. This lift station will connect to the Butterfield Dual Force Main on Mountain Avenue and will help convey wastewater to the modified RP-5 Water Recycling Plant for treatment. The new lift station will operate with two new pumps with a total of 560-gallons per minute (gpm) capacity. The new pump station will be approximately 30 feet by 10 feet, which includes the valve/meter vault and the lift station pumps. The lift station depth (i.e., pump wet well) is approximately 30 feet deep. Electricity will be delivered by a new connection to local Southern California Edison (SCE) power box P5545120. The new pump station will be installed on highly disturbed ground adjacent to Mountain Avenue and on the disturbed IEUA Solids Handling Facility site. Limited biological and cultural resources can occur on this site. In this analysis this facility will be referred to as Site 2.
3. Butterfield Force Mains: Dual force mains will be installed from El Prado Road to Kimball Avenue within the Mountain Avenue right-of-way (ROW). Both force mains are 8 inches to 14-inches diameter HDPE DR 11 pipelines; Line A is a total of approximately 6,175 linear feet, and Line B is a total of 6,200 linear feet. These two mains are needed to convey wastewater flows generated outside of Prado Basin. Primary flow will be from the Butterfield Ranch Pump Station. Lesser flows from the modified RP-2 Lift Station and from the Mountain Avenue Pump Station will be conveyed as well. These force mains will terminate at the main trunk sewer in Kimball Avenue for delivery to RP- 5. The two force mains will be installed within the disturbed Mountain Avenue ROW (shoulder to shoulder) where the roadway has been graded, filled, compacted and/or paved. In this analysis this facility will be referred to as Site 3.
4. RP-2 Lift Station: The existing lift station at RP-2 will be modified to receive flows generated within the Prado Basin from El Prado Golf Course and a private lift station on Pine Avenue. This pump station will deliver flows to the Butterfield Force Mains (discussed under item 3). The RP-2 Lift Station modifications include replacing the existing pumps at the RP-2 pump station with two smaller pumps, construction of an elevated platform for all electrical gear (to place the electrical equipment above the local 100-year flood level) and a standby generator. The work proposed for RP-2 is in response to the U.S. Army Corps raising the height of Prado Dam Spillway and the expanded zone of inundation in the Prado Basin. In this analysis this facility will be referred to as Site 4.
