Follow-up
A follow-up inspection was conducted on April 11, 2023 to determine if in-stream iron staining was still present. At the time of inspection Outfall 421 was discharging from the spillway pipe. Iron staining was present on the rocks within the spillway and extending into the UT to Tackett Creek, down the UT until its convergence with Tackett Creek. Iron staining extended approximately 40 feet down the right descending bank of Tackett Creek before dissipating.

Water quality parameters of the discharge at Outfall 421 were measured with a multimeter at the time of inspection: Temp 14.33°C, pH 6.84, conductivity 896.9 mg/L, HDO 7.71 mg/L.

This facility is out of compliance with the terms of the NPDES permit for discharging partially treated mine wastewater that resulted in iron staining in the unnamed tributary to Tackett Creek and Tackett Creek. The permittee has an approved CAP plan to prevent iron staining, but corrective actions were observed at the time of inspection.
