  1. Moorpark-Newbury 66 KilovoltSubtransmission ProjectSanta Rosa Valley MAC MeetingOctober 16, 2008

  2. Project Overview • Southern California Edison Company (SCE) is planning to construct the Moorpark-Newbury 66 kilovolt subtransmission project to address overload conditions during peak demand on an existing 66 kilovolt subtransmission line. • The project will involve both the construction of new facilities and the replacement of existing facilities within existing utility right-of-way. • The project is approximately 9 miles in length.

  3. Project Need • SCE has a responsibility to maintain service reliability and to expand and improve its electric system infrastructure when necessary to serve its customers. • SCE is constructing the project to increase electrical capacity to meet the area’s current and anticipated electrical demand. • The project would provide new and upgraded facilities that would help minimize the likelihood of electrical outages. • The project would provide SCE with enhanced operational flexibility during periods of peak customer demand.

  4. Project Location • The new Moorpark-Newbury 66 kilovolt subtransmission project will be constructed between SCE’s Moorpark Substation, located in the City of Moorpark, and SCE’s Newbury Park Substation, located in the City of Thousand Oaks. • The project will run through portions of the cities of Moorpark and Thousand Oaks and unincorporated areas of Ventura County. • The project is located within existing utility right-of-way.

  5. Project Description • Section 1: Construction of approximately 2,000 feet of underground 66 kilovolt line, entirely within Moorpark Substation. • Section 2: Construction of 34 new engineered tubular steel poles (TSPs) for approximately 5 miles, adjacent to an existing line and in existing right-of-way. • Section 3: Replacement of 14 existing double-circuit 66 kilovolt lattice steel towers (LSTs) with 14 double-circuit TSPs for approximately 2.5 miles on an existing 66 kilovolt subtransmission line. • Section 4: Replacement of 36 single-circuit wood poles with 36 double-circuit lightweight steel (LWS) poles for approximately 1.2 miles in existing right-of-way.

  6. Project Review and Approval Process • The project falls within the jurisdiction of the California Public Utilities Commission (CPUC), which is the state regulatory agency that sets electricity rates and issues permits for the construction of certain electric line and substation projects. • The CPUC’s General Order 131-D, which is the CPUC's implementation of the California Environmental Quality Act (CEQA), governs the review of certain utility facility construction projects. Due to the use of existing utility right-of-way, the project is exempt from the CPUC's requirement to file an application requesting authority to construct the project (Exemption G). • Under the exemption, SCE is required to file an Advice Letter with the CPUC notifying the agency about the proposed construction and to publicly notice the project.

  7. Construction • SCE will work with local officials, residents, and businesses to minimize the impacts of this project. Specifically, SCE will: • Comply with all applicable state and local laws, ordinances and regulations. • Provide prior notification to affected property owners of construction activities, including information on street closures and other activities that could temporarily limit access for area residents. • Provide residents and local businesses with contact information for SCE personnel who are available to answer questions that may arise during construction. • Ensure the safety and security of all construction activities. Construction equipment will be removed or secured during non-working hours; open holes and potential hazards will be covered and marked.

  8. Electric and Magnetic Fields (EMF) • Electric and magnetic fields (EMF) are invisible lines of force that surround any electrical device. Power lines, electrical wiring, appliances and electrical equipment all produce EMF. The strength of these fields decreases rapidly with distance from the EMF source. • The CPUC requires SCE to utilize no-cost and low-cost measures in the design of new facilities as a precautionary-based EMF policy to reduce public exposure to EMF. • In accordance with “EMF Design Guidelines” filed with the CPUC in compliance with CPUC Decisions 93-11-013 and 06-01-042, the following no-cost and low-cost magnetic field reduction measures will be considered for this project: • Using pole heights that meet or exceed the “preferred” 66 kV design criteria as specified in SCE’s EMF Design Guidelines. • Using a compact pole-head configuration that creates lower magnetic fields than other designs. • Phasing circuits to reduce the magnetic fields. • SCE can provide an EMF information package and free EMF measurements to our customers upon request. For more information, please call SCE’s EMF Education Group at (800) 200-4723.

  9. Project Timeline • October 2, 2008 – SCE filed Advice Letter with the CPUC. • Mid-November 2008 – Construction is scheduled to begin. • December 2010 – Project is expected to be complete.
