 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/L
Total Elemental Analysis mg/kg
 Potential risk to human health & the environment
Category 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) Beneficial Uses Projects

NR 538, Appendix I
Table 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 specifications
 Placement restrictions  Public participation process for large projects
 Submittal of notification to DNR requesting project concurrence required with some projects
 Property owner notification
 Environmental 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
 SiO 2 +Al 2 O 3 +Fe 2 O 3
 Concrete, structural fills, asphalt, soil stabilization
 Flue gas desulfurization gypsum ‐ CaSO 4
 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 landfills for fill 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 not
included 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 NR 538.08(7) Case Specific OR
2) 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
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 LINE
 Generators are ultimately responsible for the management and disposition of all their industrial byproducts which are solid waste  Know your process inputs and outputs  If the process changes, new analysis is required to verify industrial byproduct category
 Work closely with contractor or entity utilizing the byproduct Resources • WDNR Beneficial Use of Industrial Byproducts

•
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%.

Swan Park -Sledding Hill and Recreation Area
SWAN PARK (2014)
Waupaca, Wisconsin
Project Description:
Structural fill for a sledding/recreational hill,
amphitheatre, parking lot expansion and
construction of an ice skating rink. Project
designed to the city of Waupaca’s engineer, parks
and recreation department and mayor ‘s
specifications.
Project Scope:
275,000 tons of foundry sand and slag generated
from the Waupaca Foundry of Waupaca,
Wisconsin. The beneficial reuse material is being
used to provide a park expansion in a previously
unusable portion of the municipal park property.

$2,000,000 in avoided construction and materials
costs and recovery of previously undevelopable
city property.

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 costeffective fill material to achieve approximate
original contours and facilitate the proper
reclamation of a legacy mine site.

Foundry Sand as an Impermeable
Construction Material
•
•
•
•
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.
