Segment 1 Comments

No non-compliance events occurred. Voids caused by the new horizontal directional drill at Cuddy Creek (EMP 25.52 to 25.15) continue to impact Peace Valley Road. Voids have been slurried and a new pilot hole is being started. The directional drill crew is working seven-days-per-week.

Work at the Edison Tower bore (EMP 20.22) in the Tejon wetland was started. The bore Wheeler Ridge Road bore (EMP 10.61) progressed this week. Crews continued to work on the installation of the block valve at EMP 12.02. The digging of the bore pit for the south side of the California Aqueduct (EMP 12.22) began. A bore at Tecuya Creek/I-5 (EMP 9.84) is in progress, as is the bore under Access Road B (EMP 6.00).

At Emidio Pump Station (EMP 0.0), electrical work continued. Beams for the substation were being placed as was piping for the pumps. At Grapevine Pump Station (EMP 15.51 to 15.57) construction of a retaining wall was completed and concrete pouring began for the retaining wall and the pipe vault.

No project memos were issued this week.

Segment 1 Schedule for Next Week:

Continue general construction activities and bores for the mainline crews. The station crews will continue with electrical work and concrete pours. If the current attempt to directional drill Cuddy Creek is not successful, open-trench and conventional bore techniques will be implemented.

C. SEGMENT 2A CONSTRUCTION PROGRESS

This segment within the Angeles National Forest (ANF) involved very steep slopes and required significant time and additional equipment for trenching, stringing, and other pipe-laying activities. Although general construction was completed in this segment last year, a number of supplemental activities began in June to repair damage to ANF roads and the pipeline ROW caused by winter rains. Segment 2A EM, Lynn Stafford, has been on-site during construction. PPSI has one craft inspectors and one environmental inspector inspecting the work of approximately 25 contractor employees.

Construction progress September 28 through October 3, 1998, included electrical work at valve sites, and repair of pipe anomaly at EMP 38.90. No non-compliance events occurred and no project memos were issued. Electrical work will continue, as will restoration and revegetation of repair site and repair of access rads in coordination with ANF personnel. Hydrotesting is planned for mid-October.
