This approach will in turn decrease the risk to human health <br />and the environment caused by SSOs. <br />Many spills are preventable through proactive attention on sanitary sewer system <br />management using the best practices and technologies available to address major <br />causes of spills, including but not limited to: <br /> Blockages from sources including but not limited to: <br />o Fats, oils and grease; <br />o Tree roots; <br />o Rags, wipes and other paper, cloth and plastic products; and <br />o Sediment and debris. <br /> Sewer system damage and exceedance of sewer system hydraulic capacity from <br />identified system-specific environmental, and climate-change impacts, including but <br />not limited to: <br /> <br />ORDER 2022-0103-DWQ December 6, 2022 <br />12 <br /> <br />
