Materials Management
• Purchasing
• Storage
• Usage
Purchasing
Order in appropriate amounts
• Avoid expiration
• Avoid storage problems
Inspect immediately upon delivery
• Leaks
• damage
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
Storage
What are we storing?
• Stuff
• STUFF
Storage basics
• Store all fluid products & wastes indoors or under cover
Storage basics
• Inspect storage area for points where spilled products could migrate; avoid storing, dispensing or mixing products there
Storage basics
• Organize the storage area and keep an inventory
• Keep unused products in their original containers
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
Storage basics
• Bagged or boxed products that are stored outdoors should be on pallets and covered prior to rain
Storage basics
• Store waste materials and garbage in dumpsters with lids
– Away from concentrated flows
Storage basics
• Locate stockpiles away from water bodies, inlets & concentrated flows
Storage basics
Storage basics
• Salt and salt/sand piles enclosed or covered by resistant shelter
Storage basics
• Store bulk materials and tires under roofs or tarps
Storage basics
• Use berms or dikes for containment
Contained?
Sweepings
Sweepings
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
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
Two sweepings piles?
• One for amount we estimate to reuse
• One for temporary storage prior to transport to landfill
• Both contained and covered!
Usage
Keeping runoff in mind
• Keep containers closed except briefly while in use
Keeping runoff in mind
• Use self-closing spigots & nozzles for dispensing fluids from bulk containers
• Place drip pans beneath hose/pipe connections
Keeping runoff in mind
• Pour & mix products in well-ventilated area over a spill pallet
Pouring & mixing
• Mix & load bulk materials in designated area away from flow paths– Clean up excess &
spills– Minimize transfers
during wet conditions
Keeping runoff in mind
• Avoid accumulating multiple partly-used cans in the work area
Keeping runoff in mind
• Return empty containers before using new supplies
• Seal drums & containers prior to transport
Keeping runoff in mind
• Before you start using materials, make sure spill cleanup materials are readily available
Keeping runoff in mind
• Use dry cleanup methods
Public Works Facility Operations & Maintenance for Stormwater
Management: Employee TrainingBrought 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.
