Addendum to the Facilities Master Plan Program EIR for the RP-5 Expansion Implementation Project

Pull Box: The Site Plan improvements have been funded and authorized by IEUA, but after the authorization Southern California Edison (SCE) notified the Agency that the existing pull box in the park, located west of IEUA’s Headquarters Building, would have to be replaced to serve the new RP-5 facilities. A pull box consists of a concrete vault in the ground that will allow SCE to pull wire from an adjacent SCE power pole or vault through buried conduit. The existing pull box as being located in close proximity to El Prado Road in the park. The new conduits that will be installed within the RP-5 site has already been addressed as part of the FMP PEIR evaluation of the whole RP-5 site plan. Therefore, the only the facility location not previously evaluated are the new pull box and removal of the existing pull box both in the park. At this location the existing pull box will removed and the new pull box will be installed. Once the pull box is installed the new wires will be pulled through the existing conduit to connect the RP-5 facilities with SCE’s electrical grid. RP-2 Contractor Laydown Area: Based on discussions with contractors during design, it was concluded that additional “laydown” area may be required for large bulky materials required for RP-5 construction activities. IEUA selected an existing disturbed and currently unused area at RP-2 to provide additional laydown area for the contractor. It is anticipated that this area will be used for bulk materials, such as imported fill material, or similar bulky materials. Note that all equipment and high value materials will be stored at the existing, more secure, RP-5 site. The materials stored at RP 2 will be transported to RP 5 on an as-needed-basis by large trucks, such as dump trucks or semi-trailers. A maximum of 30 trips per day will be allowed from the laydown site to the RP-5 construction site. Total daily vehicle miles traveled (VMT) is estimated to be about 30 miles per day. The laydown site will be used for the duration of the RP-5 construction project. After the completion of the RP-5 project, RP-2 will be decommissioned and the site (including the laydown area) will be demolished and restored as a separate future project.
