6. Logistics and Format Review of handout packet Agenda review Informal – your input needed! Respect and courtesy - there are no bad questions! Sign in for our records Please turn off cell phones.

7. Today’s Topics: Why stormwater matters – Impacts of stormwater runoff – Exercise: Map stormwater flow through the DPW facility. Session 1 Objectives: Understand how stormwater pollution is affecting our local streams and ponds. Recognize how stormwater flows through our facility and where it ends up.

8. Why Stormwater Matters

9. Water Pollution in RI? Public perception and progress Industrial & municipal discharges CSO improvements Fields Point

10. …And the major source of pollution to RI waters Stormwater pollution is now the #1 water quality problem in the U.S.

11. In R.I. 22% of surface waters are not meeting fishable swimmable standards due to stormwater pollution. - RIDEM In recent years, up to 75% of annual beach closures were traced to stormwater, with the remainder due to CSOs - RI Health

12. What is Stormwater pollution? Rainwater falling on roads, parking lots and other impervious surfaces picks up oil, spills, road sand and salt, sediment from construction sites, fertilizers, animal waste and discharges it to the nearest stormdrain without treatment. http://www.oceanservice.noaa.gov/education/kits/estuaries/media/supp_estuar09c_pathogens.html

13. Waterflow in undeveloped areas

14. 50% 10% runoff 15% Development Impacts on Water Flow 30% 40% 55%runoff

15. Increased runoff quantity Erosion Development Impacts on Water Quantity Flooding

16. Sediment Nutrients Bacteria & viruses Oil, toxics Debris Road salt Thermal Stress Development Impacts on Water Quality More Runoff = More Pollutants

17. Why focus on public works facilities? Water Quality Materials used or stored can pollute stormwater Water Quantity High pavement, high runoff Sediment Nutrients Bacteria Oil, toxics Trash Road salt Thermal Stress

18. Polluted Stormwater: Water Quality Impacts Organic matter impairs taste & odor Toxics– makes fish unsafe to eat Nutrients lead to low dissolved oxygen and fish kills. Algae and aquatic plants limit recreational use.

19. Summary We’ve made a lot of progress in controlling water pollution to our rivers, lakes and bay. Now managing stormwater pollution is the next step to keep our waters clean and healthy. Stormwater pollution comes from many small sources with no single solution. But it takes just a few simple steps to get started.

20. Public Works Facility Operations & Maintenance for Stormwater Management: Employee Training Brought to you by: This program was developed by the Southern Rhode Island Conservation District in partnership with the URI Cooperative Extension RI NEMO Program and the Rhode Island T2 Center. Funding was provided by the RI Department of Environmental Management and the RI Department of Transportation under the Phase II Stormwater Education and Outreach Program.

21. Exercise! Inspect map(s) of facility site and surrounding area. Draw water flow patterns on site map. What downstream resources could be affected? How does stormwater flow through our facility?
