Threemile Slough Pipeline Crossings Remediation and Decommissioning Project

Threemile Slough Pipeline Crossings Remediation and Decommissioning Project

Pacific Gas and Electric Company (PG&E) is proposing the Threemile Slough Pipeline Crossings Remediation and Decommissioning Project (Project), which consists of four primary components: project area preparation and equipment mobilization, remediation of the active L-131Y and L-131Z pipelines within Threemile Slough, removal of the terrestrial and submarine portions of the previously abandoned L-131 East and West pipelines, and post-construction restoration of the Project area and demobilization activities. Each Project component includes a defined series of steps summarized in the Mitigated Negative Declaration. Long-term operations of the active L-131Y and L-131Z pipelines would not differ from existing conditions.
