PennEast Construction Plan

According to the final draft of PennEast’s Resource Report 01 (2014), the typical pipeline construction process consists of the following steps:

1. Survey/demarcate the route and approved workspace.
2. Centerline survey of existing or proposed pipelines.
3. Clearing – remove vegetation from construction work area (CWA); installation of erosion and sediment controls.
4. Additional protection of adjacent pipeline, as necessary; grading to establish safe workspace; completion of installation of erosion and sediment controls.
5. Trenching – pipeline trench excavation to design depths.
6. Stringing – placement of pipe joints along the trench line.
7. Bending – bending pipe joints, as needed, for route and terrain.
8. Weld pipe.
9. Pipe integrity – visual inspection, non-destructive examination (NDE) of welds.
10. Weld coating – corrosion protection and waterproofing.
11. Pipe placement – pipe placed in trench, tied to previously laid sections, backfilled.
12. Hydrostatic testing – confirmation of pipeline segments.
13. In-line tool inspection of new pipeline segments.
14. Tie-in to existing pipeline, purge, pack new section with gas.
15. Grade restore of CWA to previous contours.
16. Final clean-up, restoration, and seeding.
