Question # 666

666. In the current reporting year, a mining facility exceeded a threshold for copper compounds and reported releases to land of copper in waste rock tailings. If that same waste rock or tailings are beneficiated in the subsequent reporting year, is the disposal of the resulting wastes from the processing of the waste rock considered a release to land?
Yes. The facility is required to report the copper in the waste rock tailings as a release to land in both the current reporting year and in the subsequent reporting year. The facility must report the releases and other waste management activities that occur in each reporting year for material that undergoes a non-exempt activity (i.e., facility is not required to consider any further releases of materials that have been disposed of and are not subjected to further management activities).
