Potholing Activities Along the San Jacinto Pipeline
Document Type
NOE - Notice of Exemption
Document Description
The Metropolitan Water District of Southern California (Metropolitan) proposes to conduct potholing activities in three locations (Stations 110+00, 120+00, and 130+00) along the San Jacinto Pipeline. The potholing activities are necessary to conduct soil sampling for corrosion analysis and to measure the pipeline corrosion potential on the surface of the pipeline. Soil will be excavated to the top of the pipeline (approximately seven feet) using a vacuum truck and sampling will be performed using hand-held instruments. Excavation pits will be approximately two feet in width by two feet in length. Once sampling is complete, the excavations will be backfilled using the same soil originally removed from the excavated area.
