  4. StructuresDos and Don’ts Do’s • Do remove sediment, debris & trash from inlet & outlet structures such as curb cuts, rip rap, sumps & grates. • Do control and handle the removed sediment so it won’t get back into the storm system. • Do prevent excessive ponding by inspecting underdrains. • Do prevent flooding by clearing outlets of obstructions. • Do protect the integrity of structures such as curbs, & walls. • Do inspect less durable materials more often.

  5. StructuresDos and Don’ts • Do inspect culverts to look for UV degradation, cross-section shape changes that may cause flooding, and corrosion.

  6. Erosion Prevention • Erosion prevention is any practice that protects the soil surface and prevents the soil particles from being detached by rainfall or wind. Green Girl LDS

  15. Erosion Prevention & Sediment ControlDos and Don’ts Do’s • Do prevent erosion by keeping soil covered and getting plants established. • Do prevent erosion by staying out landscape areas when possible. This also prevents soil compaction, which slowly kills vegetation and creates erosion long-term. • Do control sediment when erosion cannot be prevented by using wattles & filter sacks.

  16. Spills OR Department of Environmental Quality

  17. Clean up the spill OR Department of Environmental Quality • Do • Determine what type of material has spilled • Block stormwater inlets • Use absorbent material to contain the spill • Remove contaminated soil from facility • Protective gear for workers

  19. Notify the appropriate authorities Photo: morgueFile • Do • Contact owner of the facility • Contact local jurisdiction emergency response • Contact OR Emergency Response 800-452-0311

  20. Spills • Do • Document the spill in the O&M report
