1. Part 4 - Materials Management Preventing Stormwater Pollution at Your Public Works Facility: A 5-Part Workshop Series

2. Training Modules 1.Why Stormwater Matters 2.What is a SWPPP? 3.Spill Prevention & Response 4.Materials Management 5.Good Housekeeping

3. Materials Management Purchasing Storage Usage

4. Purchasing

5. Order in appropriate amounts Avoid expiration Avoid storage problems

6. Inspect immediately upon delivery Leaks damage

7. Consider alternative products Multi-purpose to reduce numbers Review Material Safety Data Sheets (MSDS) prior to purchase Ask for least hazardous materials suitable to job

8. Storage

9. What are we storing? Stuff STUFF

10. Storage basics Store all fluid products & wastes indoors or under cover

11. Storage basics Inspect storage area for points where spilled products could migrate; avoid storing, dispensing or mixing products there

12. Storage basics Organize the storage area and keep an inventory Keep unused products in their original containers

13. Storage basics Properly store wastes –Plainly label containers Date when contents first added Indicate hazard (e.g. flammable) –Batteries in single layer on pallets with non-corrosive base Recycle

14. Storage basics Bagged or boxed products that are stored outdoors should be on pallets and covered prior to rain

15. Storage basics Store waste materials and garbage in dumpsters with lids –Away from concentrated flows

16. Storage basics

17. Locate stockpiles away from water bodies, inlets & concentrated flows Storage basics

18. Salt and salt/sand piles enclosed or covered by resistant shelter

19. Storage basics Store bulk materials and tires under roofs or tarps

20. Storage basics Use berms or dikes for containment

21. Contained?

22. Sweepings

24. Acceptable Uses for Sweepings Landfill cover material (may require screening) Base course to be covered with asphalt or concrete Backfill for public works construction projects Mixed with new sand/salt and reapplied

25. Sometimes acceptable use Clean fill, but… –Analytical testing for petroleum hydrocarbon content, Toxicity Characteristic Leaching Procedure, total lead content must prove no potential threat to human health or environment –Sampling plan and analytical results must be submitted to Office of Waste Management for review & approval

26. Two sweepings piles? One for amount we estimate to reuse One for temporary storage prior to transport to landfill Both contained and covered!

27. Usage

28. Keeping runoff in mind Keep containers closed except briefly while in use

29. Keeping runoff in mind Use self-closing spigots & nozzles for dispensing fluids from bulk containers Place drip pans beneath hose/pipe connections

30. Keeping runoff in mind Pour & mix products in well-ventilated area over a spill pallet

31. Pouring & mixing Mix & load bulk materials in designated area away from flow paths –Clean up excess & spills –Minimize transfers during wet conditions

32. Keeping runoff in mind Avoid accumulating multiple partly-used cans in the work area

33. Keeping runoff in mind Return empty containers before using new supplies Seal drums & containers prior to transport

34. Keeping runoff in mind Before you start using materials, make sure spill cleanup materials are readily available

35. Keeping runoff in mind Use dry cleanup methods

36. 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.

37. Exercise! How would you evaluate the materials management in the following pictures?

39. Activity/BMP (Category)Does it work? (Materials Management) Loading area covered Movement during wet weather Run-on diverted Drains to dead-end sump Red

41. Activity/BMP (Category)Does it work? (Vehicle/equipment fueling) Overhanging roof Spill materials at hand No stormwater runon Red Yellow

43. Activity/BMP (Category) Does it work? (Waste handling) Out of runoff flow path Bulk waste confined & covered Accumulated sediments removed (Runoff management) Runoff directed to treatment area Activity/BMP (Category) Does it work? (Outdoor storage) Protected by roof/cover Erosion controls around large stockpiles Berms & curbs prevent runon, runoff Red

45. Activity/BMP (Category)Does it work? (Outdoor storage) Protected by roof/cover Berms & curbs prevent runon, runoff Red Orange/Yellow

47. Activity/BMP (Category) Does it work? (Outdoor storage) Protected by roof Containers in good condition Lids secured Labeled & stored in secure area Activity/BMP (Category)Does it work? (Waste handling) Fluids in good condition, labeled containers under cover Red Orange Red

49. Activity/BMP (Category)Does it work? (Outdoor storage) Inventory minimized Protected by roof Yellow/Green Green
