WISCONSIN INDUSTRIAL BYPRODUCTS 2000 – 2013
NR 538.03(4) Specific high‐volume industrial byproducts: paper mill sludge, coal ash, flue gas desulfurization material, foundry sand & slag, lime kiln dust, Other non‐hazardous solid waste with similar characteristics
Creates 5 categories of industrial byproducts Specific uses are allowed for each category
Industrial Byproducts
RCRA non‐hazardous Category (1‐5) assigned based on lab analysis ASTM Water Leach Test mg/LTotal Elemental Analysis mg/kg
Potential risk to human health & the environmentCategory 1 = few restrictions on use Category 5 = most restrictions on use & placement
Category standards based on:NR 140 (drinking water)NR 105 (surface water quality) NR 720 (soil cleanup)

NR 538, Appendix ITable 4
*Byproducts and uses need to meet structural and physical specifications and generally accepted engineering practices for the use.
Obligated to meet all other Federal, State & Local permits, zoning and regulatory requirements that may apply.
Regulatory Requirement Overview*
Initial & annual reporting Industrial byproduct testing Storage & transportation requirements Project‐specific specificationsPlacement restrictions Public participation process for large projects Submittal of notification to DNR requesting project concurrence required with some projects
Property owner notificationEnvironmental monitoring – large volume DOT embankment projects
* see code for all requirements
Coal Combustion Residuals
Bottom Ash – coarse to fine‐grain, sand‐like Structural fills, road bases and sub-bases,
aggregate for concrete, asphalt and masonry,
Fly Ash – fine powder, silt, cementitious SiO2+Al2O3+Fe2O3
Concrete, structural fills, asphalt, soil stabilization
Flue gas desulfurization gypsum ‐ CaSO4 Agricultural soil amendment*, source of plant
nutrients Ca & S, wallboard, cement manufacturing
and concrete production
*as allowed by NR 538.08(7)
Foundry Byproducts
Spent sand from mold process Geotechnical & structural fills, paved roadway base, sub-base,
embankments
Slag Cement manufacturing, aggregate replacement
Category 2
Paper Mill Byproduct
Pulping sludge used as raw material to make “soil”**as allowed by NR 538.08(7)
Used in mine reclamation, on landfil ls for fil l purposes or to establish rooting zone for final grass cover
NR 538.08(7) Case Specific
• Allows the DNR to:1) assign a category to a high volume solid waste notincluded in the definition of industrial byproduct
Examples – Foundry baghouse dust containing high % of
foundry sand from molding & unmolding process– Non‐ferrous foundry spent sand or slag
OR2) Conditionally approve a use not specified in rule at NR 538.10 for an industrial byproduct
Examples – Beneficial use of material captured in flue gas desulfurization systems and paper mill sludge used for agricultural soil amendment
NR 538.08(7) Case Specific
Low‐Hazard Waste Exemption
• What if….– Material is not an industrial byproduct and– Proposed use is not specified in NR 538
• Then….Investigate a low‐hazard exemption as allowed in sub. 289.43(8), Stats.
DNR publication WA‐1645 Exempting Low‐Hazard Wastes from Solid Waste Regulations
ch. NR 538.05 Solid waste rules exemption Persons who generate, use, transport or store industrial byproducts that are characterized and beneficially used are exempt from licensing under s. 289.31, Stats, and the regulatory requirements in chs. NR 500 to 538.
HOWEVER If industrial byproducts are improperly handled and environmental problems result, the DNR will assess the cause and address the situation using administrative code and statutory authority
BOTTOM LINEGenerators are ultimately responsible for the management and disposition of all their industrial byproducts which are solid waste Know your process inputs and outputs I f the process changes, new analysis is required to verify industrial byproduct category
Work closely with contractor or entity uti l iz ing the byproduct

FET Sustainability Webinar - Beneficial Reuse and Recycling, March 27, 2015
Goals (2020):• Reduce energy use intensity by 25%.• Promote alternative processes and maintain state of
the art pollution control technologies.• Reduce spent foundry sand generation by 30% while
promoting offsite reuse/recycling opportunities of the remaining spent foundry materials to achieve zero landfill disposal.
• Reduce water use consumption by 80%.

Foley Pit Mine Reclamation
MINE RECLAMATION (2005)Waupaca, Wisconsin
Project Description:Foundry sand was used as an unconfined geotechnical fill material in the reclamation of the Foley Sand/Gravel Pit. The foundry sand was placed at 3:1 horizontal to vertical slope and then covered with 18 inches of native soil and 6 inches of topsoil extending to the top of the pit sidewalls.
Project Scope:90,000 yd3 of foundry sand and slag generated from the Waupaca Foundry of Waupaca, Wisconsin.
Project Benefit: The foundry sand proved to be a safe and cost-effective fill material to achieve approximate original contours and facilitate the proper reclamation of a legacy mine site.

Foundry Sand as an Impermeable Construction Material
FET Sustainability Webinar - Beneficial Reuse and Recycling, March 27, 2015
• Select foundry sand exceeds the environmental barrier requirements for landfill construction projects.
• Select foundry sands may contain up to 15 percent clay
• Can be used as a sustainable alternative to native clays in construction projects requiring impermeability barriers.
• Referenced in USDA-NRCS 313 guideline for manure pit construction sub-base fill.

Make it easy Think outside of the box Always talk to the person next to you on an
airplane WDNR can help – Conditional exemptions,
Small business office, Green Tier Represent material as waste – end user
determines acceptable for application
