Diablo Canyon is implementing a License Amendment which changes the Diablo Canyon emergency plan staffing such that Shift Control Technicians are no longer required for the onsite emergency plan watchbill. Because of this change, on-shift reliefs are no longer required. The purpose of this agreement is to establish a shift schedule which is needed to support the work and establishes a process for manning the shift schedule. This Letter of Agreement cancels and supersedes L/A 10-02-PGE. The Company proposes the following terms and conditions to establish a second (2nd) shift and a weekend shift in the Maintenance Department of Diablo Canyon Power Plant for the Instrumentation and Controls Maintenance (I&C) discipline.
