| Pastoria Pipeline |
The Pastoria Pipeline called for the installation of 14.05 miles of 20-inch natural gas pipeline. This included fabrication and installation of associated facilities consisting of a meter/regulator station with filter separator, scrubber, storage tank and pig receiver at the Pastoria Energy Facility and a pig launcher and tie-in facilities at the connection point with Mojave Kern River and other related facilities.
The project was originally bid for the installation of 12.2 miles of pipeline. Prior to award and due to the presence of Blunt-Nosed Lizard in the area, two re-routes occurred, which added approximately 11,000 feet to the project increasing the total distance to 14.05 miles.
Approximately 3 miles of pipe were laid under pavement. This entire section required solid sheet shoring due to extremely sandy soil conditions.
Due to permit problems, a section of the project had to be skipped requiring the crew to move to another location which left the highway and continued through a hilly section, most of which is located on the Tejon Ranch (approximately 8 miles). Soil conditions in this area became hard and rocky requiring the use of a ripper. There were many cattle fences on the Tejon property and numerous fence gaps had to be maintained. All vehicles required fire permits and water trucks were used for fire protection.
Silt fences were installed for approximately 12,000 feet at various creek crossings. Soil excavated from the creek crossings was set aside and reused in the creek backfill. Culverts were used to divert the water and hay bales were used for filtration. The crews worked with on-site geologists at all creek crossings.
