PROJECT MEMORANDUM - PACIFIC PIPELINE MITIGATIONMONITORING, COMPLIANCE, AND REPORTING PROGRAM

 

WEEKLY REPORT (April 13 through 19, 1998)

A. INTRODUCTION

Construction continued on Segment 1 (Milepost [MP] 0 TO 33), Segment 2B (MP 56 to 73); Segment 3 (MP 73 to 99), Segment 4A (MP 99 to 108), Segment 4B (El Segundo MP 0 to 11) and Segment 5 (MP 108 to 118).

B. SEGMENT 1 CONSTRUCTION PROGRESS

This segment extends southward from the southern end of the San Joaquin Valley (Emidio), through the Tejon Pass, to the northern perimeter of the Angeles National Forest. Construction will occur through agricultural fields, along roads and across very steep slopes. Segment 1 Environmental Monitor (EM), Lynn Stafford has been on-site during construction. PPSI has five craft inspectors, one environmental inspector, one Native American monitor, and one contaminated soils monitor inspecting the work of approximately 65 contractor employees. Construction progress from April 13 through 17, 1998 included the following:

Segment 1 Activities:

Activity Milepost (approximate)

• Pot-hole 21.45 (no progress)

• Coating 24.10 to 23.80

• Trench 23.89 to 23.46

• Conduit 24.16 to 23.83

• Lower-In 24.03 to 23.75

• Backfill 24.16 to 23.83

Segment 1 Comments:

No non-compliances occurred. Construction is being inspected by both Kern County and Los Angeles County construction inspectors. Finish-work (coating) was performed at Block Valve #10 (EMP 32.81). Excavation for tie-in of Block Valve #9 (EMP 30.45) was begun. The underground directional drill pipe at Gorman Slide (EMP 25.94) was filled with water in preparation for the hydrotest on Monday, April 20. On April 16, a telephone cable in a shallow trench was damaged when some of the ground under stored spoil was scraped off by a piece of equipment that was loading spoil for placement back in the trench. All contacts were made and service was restored within 24 hours. On April 15, Segment 1 was shut down by the California Highway Patrol to allow traffic that had been rerouted from Interstate 5 (because of snow) to use the frontage road for passage. On April 14 bouts of rain, sleet and snow slowed, but did not shutdown, construction activities.

Segment 1 Schedule for Next Week:

Continue construction along Lebec Road and finish work at Block Valves 9 and 10.

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. All construction activities to Templin Highway, except revegetation, were completed by November 9.

A helicopter fly-over inspection with representatives from ANF, Aspen, and PPSI was canceled due to white-out (snow) conditions and will be rescheduled the week of April 20.

D. SEGMENT 2B CONSTRUCTION PROGRESS

This segment is primarily in open lands and roadway right-of-ways from Castaic to Sylmar. Segment 2B EM, Chris Fazzari, has been on-site during night construction and Lead EM, Kris Thorne, has been on-site during day construction. PPSI has six craft inspectors, one environmental inspector, and one Native American monitor inspecting the work of approximately 95 contractor employees. Construction progress April 13 through 17, 1998 included the following:

Segment 2B Activities:

Activity Milepost (approximate)

• Pot-hole 63.46 to 64.68

Construction through the intersection of Magic Mountain Parkway and The Old Road was performed at night (10:00 p.m. until 7:00 a.m.) The fiber optic conduit near EMP 62.82 did not pass the sizing test and was excavated and repaired. Water trucks were spraying water to help control dust along the ROW. On April 13, an unmarked 0.5 inch gas line was cut during excavations. All notifications were made and repairs were completed within 4 hours. Service was not interrupted to any customers. On April 14, an unmarked water line was broken during trenching. Notifications were made and the owner repaired his pipe.

Segment 2B Schedule for Next Week:

Construction completed through Magic Mountain Parkway intersection, so night shift will be discontinued. Potholing and clearing to being south of Valencia Blvd in undeveloped lands adjacent to Interstate 5

E. SEGMENT 3 CONSTRUCTION PROGRESS
