Document Description
The Project objectives are maintenance of three pipeline areas by either permanently decommissioning and replacing previously retired pipelines and/or reducing pipeline exposure due to erosion; thereby improving the operating condition and safety of the system in each area. PG&E intends to decommission the previously retired 8-inch diameter Line 137B Freshwater Slough crossing under the slough bed (R-354), replace and decommission the existing 4-inch diameter Line 137C (L-137C) Ryan Slough crossing that is currently exposed in the slough bed (R-519), and to remediate the erosion issues resulting from water flowing across an earth berm that runs along the west side of Ryan Creek (RT-102).
