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
Storage basics

• Locate stockpiles away from water bodies, inlets
  concentrated flows

18
Storage basics

• 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
23
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

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.
