Continue bore under I-5 at Lebec and prepare for bore under I-5 at Grapevine. Continue work at Grapevine Pump Station and mainline activities.
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 have recently begun. Winter rains caused damage to ANF roads and the pipeline ROW. Lead EM, Kris Thorne, has been on-site. PPSI has one craft inspector and one environmental inspector inspecting the work of approximately 15 contractor employees.
Work on pads for valve sites between Copco Road and Reservoir Summit continued. Installation of pull boxes for fiber optic cable was started. No non-compliance events occurred. Both activities will continue next week.
