Project Description:

Line 1600 is a high pressure pipeline located in San Diego County that runs from
Rainbow Station to Mission Station. The scope for remediating Line 1600 for PSEP
compliance is to replace approximately 37 miles of existing 16-inch diameter pipeline
in HCA areas and hydrotest the remaining 13 miles in non-HCA areas. The overall
project has been broken into 19 individual segments. The proposed Line 1600
Hydrotest/Replacement Project was approved by the CPUC Safety and Enhancement
Division in January 2019.
