Stormwater Evaluation Guidance

This document provides guidance cleanup project managers may use when evaluating the potential for stormwater discharges from an upland site to impact sediments, surface water or aquatic organisms in the receiving waterbody.

The appendices are designed to provide responsible parties with clear direction for developing workplans and reports in order to minimize the effort both project managers and responsible parties need to expend to ensure each deliverable meets DEQ’s expectations and needs.
