Salt Transportation
• Producers transport salt to IL by barge up the Mississippi River and then the Illinois River
• IL salt supply dependant on IL River

Salt Storage
• Road salt producers contract with 3rd party bulk storage and transportation facilities
• Salt producers retain title to all salt until sold to consumers for road deicing
• Storage facilities build large stockpiles from which trucks load for delivery to consumers
• Salt producers retain responsibility to cover stockpiles

Constituents of Road Salt
• Sodium Chloride (NaCl) • Sodium Ferrocyanide (Yellow Prussiate of Soda)
– Anti-caking additive – Required by IDOT contract specifications – Iron cyanide compound (“Prussian Blue”) – Exposure to shallow water and sunlight leads to
decomposition that releases free cyanides, which can be extremely toxic to aquatic organisms

Threatened Waters
• Surface waters – IL RIVER – Tributaries & drainage channels – Collection ponds
• Ground waters – Sankoty Aquifer – Unconfined aquifers – High potential for contamination
![Page 14: Water Quality Impacts of Transportation and Storage of](https://reader031.vdocument.in/reader031/viewer/2022022606/6218684f82ba2a51e922f927/html5/thumbnails/14.jpg)
So What’s the Problem??
• It’s all about the QUANTITY • Stockpiles range from 50,000 to 150,000 tons • Large-Scale Concerns:
– Eliminating/reducing storm water contaminated – Prevent leaching of contaminated storm water to
ground waters – Prevent discharge of contaminated storm water to
surface waters

Impacting Receiving Waterways

What are our Legal Protections? Section 12 of the Illinois Environmental Protection Act (415 ILCS 5/12 (2012) No Person Shall:
(a) Cause or threaten or allow the discharge of any contaminants into the environment in any State so as to cause or tend to cause water pollution in Illinois . . . or so as to violate regulations or standards adopted by the Pollution Control Board. . . .
(d) No person shall deposit any contaminants upon the land in such
place and manner as to create a water pollution hazard. (f) No person shall cause threaten or allow the discharge of any
contaminant into the waters of the State . . . without an NPDES permit . . .

Water Quality Standards
• Section 302.208 of the Board’s Water Pollution Regulations sets numerical water quality standards for waters of the State: – Chloride: 500 mg/l – Dissolved Iron: 1.0 mg/l – Free Cyanide: 22 ug/l
• Sampling of State waters at enforcement sites have shown: – Chloride: 200,000 mg/l – Dissolved Iron: 2.0 mg/l – Free Cyanide: 8,000 ug/l
![Page 26: Water Quality Impacts of Transportation and Storage of](https://reader031.vdocument.in/reader031/viewer/2022022606/6218684f82ba2a51e922f927/html5/thumbnails/26.jpg)
How do we enforce our legal protections?
• Permit requirements – Storm Water Pollution Prevention Plans (SWPPPs)
• No regulations dictating industry standards • Left to industry to determine how to achieve
compliance with permits & pollution prohibitions
• Salt Institute Guidelines provide operational standards to protect product & environment
![Page 27: Water Quality Impacts of Transportation and Storage of](https://reader031.vdocument.in/reader031/viewer/2022022606/6218684f82ba2a51e922f927/html5/thumbnails/27.jpg)
Enforcement Initiative (as of today)
• 4 sites & all 3 Big Salt producers have received Violation Notices from IEPA – all along IL River
• 3 sites have been referred to IAGO – all Peoria • 2 lawsuits have been filed & have interim
orders on file requiring sampling & imposing operational requirements
• Additional facilities have been identified • Inspections will continue along River and
throughout State

What We Want
• Streamlined process reducing exposure time • Improved conveyors & daily housekeeping • Engineered impermeable storage pads • Indoor storage or Diligent coverage • Containment of contaminated storm water • Collection of contaminated storm water • Impermeable liner of any collection ponds • Proper treatment or disposal
