DEQ releases proposed plan for cleanup of Joslyn Street tailings facility

HELENA –  The Montana Department of Environmental Quality is seeking public comment on the proposed cleanup plan for the Joslyn Street Tailings State Superfund Facility in Helena. The public is encouraged to attend a meeting at 7:30 p.m. on Thursday, June 13, at the Lewis & Clark Library at 120 S. Last Chance Gulch.


The proposed plan summarizes the cleanup options DEQ evaluated to address remaining metal contamination in soil and groundwater at the Facility and identifies DEQ’s preferred option. The public is encouraged to offer suggestions for improving the proposed cleanup measures, or to submit reasons to implement other alternatives for the project.


The proposed cleanup plan consists of:

  • Removal and off-site disposal of contaminated soil
  • Monitored natural attenuation of contaminated groundwater
  • Property and groundwater use limitations for certain areas


The final plan for cleaning up the Facility will be documented by DEQ in a Record of Decision after DEQ considers each public comment submitted during the 30-day public comment period, which starts June 1 and ends July 1.
