Endangered species preactivity survey and monitoring program for Western Area Power Administration's Tracy-Livermore 230-kV transmission line construction. Final report

摘要

The Department of Energy (DOE), San Francisco Field Office, requested the establishment of a transmission line between Lawrence Livermore National Laboratory (LLNL) and the Western Area Power Administration (Western) Tracy Substation near Byron, California. Western was responsible for providing this interconnection by designing, constructing, operating, and maintaining the 230-kV transmission line between the Tracy Substation and a new substation at LLNL. The 12.6 mile proposed transmission line route and alternative routes were surveyed in 1986 and 1987. These surveys were used to write a Biological Assessment of the effects of construction and operation of the proposed transmission line on threatened and endangered species and species of concern. On February 1, 1988, Western requested formal consultation with the US Fish and Wildlife Service (FWS) to determine potential impacts of the proposed project on the federally listed endangered San Joaquin kit fox (Vulpes macrotis mutica) and palmate-bracted bird's beak (Cordylanthus palmatus). FWS further required that a report be issued upon project completion which would: detail results; address the adequacy of mitigation and conservation measures; document difficulties encountered in implementing the measures; and recommend improvements in protective measures to be applied towards future projects. This report has been prepared to meet these requirements.
