Abstract: The Kemess Mine is located in north-central BC and has a disturbance area of greater than 1,000 ha. Federal Metal Mining Effluent Regulations (MMER) require that total suspended solid concentrations be below 15.00 mg/L as a monthly average and 30.00 mg/L as a grab sample maximum in the regulated surface waters leaving the mine site. Surficial materials at the mine have a relatively high fines content, which make the removal of suspended solids from impacted water difficult. Therefore, sediment management is an integral component of the operations at the site in order to achieve the MMER targets. This paper describes the sediment management practices including recovery of sediment or tailings accumulations in stream beds at the Kemess Mine. Kemess Mines targets permit compliance through the application of applied sediment management techniques discussed in this paper. These techniques are utilized as part of a toolbox approach to resolving sediment issues. A combination of techniques is applied dependent on site specific conditions to provide the most cost effective method for the maintenance of water quality and minimization of impact.
