SOP_-_I-1005_11042019.pdf

This document is a Standard Operating Procedure (SOP) for Prevention of Aquatic Invasive Species Introduction developed by Seattle City Light, effective November 4, 2019. The SOP provides a comprehensive multi-pronged approach to preventing the introduction and spread of aquatic invasive species (AIS) in project watersheds, specifically targeting the Skagit and Boundary projects, Cedar River, and South Fork Tolt River watersheds. The primary goals include prevention of new AIS introductions, containment of spread, and control or potential eradication of established invasive species populations.

The procedure outlines specific responsibilities for City Light Business Units, requiring personnel to undergo training on AIS pathways, environmental consequences, management costs, and decontamination procedures. Key policy elements mandate consistent compliance with federal and state regulations, prohibiting the transportation of aquatic invasive species between water bodies and requiring completion of AIS Risk Checklists for projects. The document references multiple legal frameworks including the National Invasive Species Act, Lacey Act, and state-level regulations, demonstrating a comprehensive approach to ecological protection that aims to minimize potential significant environmental and financial impacts associated with invasive species introduction.
