Next Steps for Odor Mitigation

We are Working Parallel Paths to Address Odor Issues

Short and Medium-Term: 0-12 months

  • Continue to reduce mill material losses and flow
  • Optimize current wastewater treatment system
  • Engineering/capital gate process for long-term solution
  • Environmental permitting for long-term solution 

Long-Term Solution: ~ 18 months

  • Implement anaerobic digester system/aerobic system

Q4 2024 – Q4 2025

Execute work on modified/ alternative wastewater treatment system

Q4 2025 – Q1 2026

Start-up modified/alternative wastewater treatment system

Continue to consult with wastewater operations experts, evaluate options to supply additional oxygen to the lagoon.

Remain focused on reducing material losses and flow to the wastewater treatment system, optimize current system. 

Maintain regular addition of chemical oxidants to wastewater to minimize odor, install and evaluate other mitigation options. 

Install a mobile water clarifier to improve the overall biological health of the water treatment system, evaluate system daily to determine efficacy. 

Finalize lagoon dredge plan for solids removal in the settling zone, evaluate bids to select a vendor. 

Engineering design underway for alternative long-term wastewater treatment system; initiate applicable environmental permitting.
