  3. Preventing Stormwater Pollution at Your Public Works Facility Workshop Series Overview • Why Stormwater Matters • What is a SWPPP • Spill Prevention & Response • Good Housekeeping • Materials Management

  4. 2008 Winter Workshop Schedule All sessions held at the Town Highway Garage Street address, Meeting Room 9:00- 10:30 AM Preventing Stormwater Pollution at Your Public Works Facility

  5. Part 1: Why Stormwater Matters Preventing Stormwater Pollution at Your Public Works Facility: A 5-Part Workshop Series

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

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

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

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

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

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

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

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

  19. 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. Summary

  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?
