Deputy Administrator

Air & Waste Division

Wisconsin Department of Natural Resources

ecos resolution 08 14 the regulation of coal combustion products
ECOS Resolution 08-14The Regulation of Coal Combustion Products
  • Supports the safe, beneficial reuse of CCW, including for geotechnical fill & civil engineering
  • Calls upon USEPA: collaborative dialogue with states to develop & promote a national framework for beneficial use of CCW including use principles and guidelines, and to accelerate markets development
  • CCP & Other Industrial Byproducts  Material
    • Many State Beneficial Use Programs
    • US EPA Partnerships
astswmo beneficial use surveys 1999 2006
ASTSWMO Beneficial Use Surveys: 1999 & 2006
  • 80% of the 40 respondent states have programs
    • 64 waste materials
    • Multiple uses: fertilizer, soil amendment, raw material substitute, fill material……
    • States implementing improved programs
  • Effective Management w/ regulatory oversight (categories, generic, case-by-case, risk-based)
  • Sparse State Resources
  • Few Measurements
  • Specific 2009 Survey – Coal Ash Management
wisconsin beneficial use program key nr 538 elements
Wisconsin Beneficial Use Program: Key NR 538 Elements
  • Self implementing/Case-by-Case Approval
  • Five categories of industrial byproducts
  • Beneficial uses allowed for each category
  • Testing requirements & standards for each category
  • Notification of WDNR for larger projects
  • Annual reports on use to the WDNR
  • Property owner notification for geotechnical fill projects
wisconsin uses
Wisconsin Uses
  • Raw Material for Manufacturing
  • Cold Weather Road Abrasive
  • Confined & Unconfined Geotechnical Fill
  • Bonded & Un-bonded Surface Course
  • Waste Stabilization/Solidification
  • Supplemental Fuel Source
  • Decorative Stone
  • Re-burn of Landfilled Ash
  • Encapsulated Embankment
  • Capped Embankment
  • Landfill Daily Cover
  • Asphalt Roads

benefits of use
Benefits of Use
  • Greenhouse gas emission reductions
    • Foundry Sands: 14 – 26 tons CO2/1000yds3 used*
    • Fly Ash: 0.70 tons CO2/ton as Portland Cement Sub.*
    • FGD gypsum: 0.09 tons CO2/ton in Wallboard*
  • Energy savings
    • Foundry Sands: 146 – 293 mBTUs/1000yds3 used*
    • Fly Ash: 4mBTUs/ton as Portland Cement Sub.*
    • FGD gypsum: 11.9mBTUs/ton in Wallboard*
  • Water Conservation
  • Conserves Landfill Space
  • Economic (generator and end-user)

    • Establishes an industry goal to achieve 50% reuse by 2015
    • ASTSWMO’s Beneficial Use Task Force helping to identify key challenges and action items
    • Builds on existing resources, including the EPA “State Toolkit for Developing Beneficial Reuse Programs for Foundry Sand”
    • Potential for ECOS involvement
challenges
Challenges
  • Business Case for Industry & End-user
  • Sustainable Markets: local, regional, national
  • Infrastructure
  • Changing “Materials” (ex. Air emission controls)
  • Measurements
  • Public Acceptance/Perception
  • Resources
  • Regulatory Processes
future considerations
Future Considerations…
  • Continue collaboration amongst States, & with USEPA:
    • CCP Resolution Framework
    • Foundry Sands Action Plan
    • Larger Beneficial Use Framework
    • Risk Assessments, Life Cycle Analysis, Decision Tools
  • Connections with other federal agencies(Transportation, Commerce, Business Council)
  • Sustainable Markets Development including Public/Private Partnerships
