Document Description
The project involves Pacific Gas & Electric Company’s (PG&E’s) operation and maintenance (O&M) of approximately 645 miles of pipelines in the Mojave Desert region, which encompasses high-pressure gas pipelines and facilities. The gas transmission system consists of gas pipelines; compressor stations; associated gas transmission and distribution facilities; rights-of-way; areas up to 0.25 miles beyond the rights-of-way, where needed; and their related equipment and facilities. Most of the O&M activities in the O&M program area would result in temporary and short-term impacts to expose the pipeline for inspection or repair, or to access a given facility. The O&M activities proposed would not result in large new permanent disturbance areas. The pipeline system has been in place for more than 70 years, and O&M activities have been conducted since the pipeline system was installed. Since 2001, PG&E has been gathering data on temporary and permanent disturbance resulting from O&M activities. Therefore, the type, number, and frequency of ongoing O&M activities would continue to be a part of the baseline conditions in the O&M program area.
