Performance results
By July 1, 2017, the 6 facilities subject to the notice had submitted their final declaration (schedule 5 of the notice) summarizing the outcomes of their implemented pollution prevention plan. Five of the facilities have met the reduction target which consists either in reducing the D4 concentration in their effluents to a level that is less than or equal to 17.3 μg/L or in releasing a total quantity of D4 in their effluents that is less than or equal to 3 kg per year. The sixth facility also has fully implemented its pollution prevention plan but, despite achieving significant reductions in its D4 releases, it has not met the reduction target set out in the notice. For more information, see the performance report.
Time Extension
Les Emballages Knowlton Inc. (LEKinc.) was granted a time extension to prepare their pollution prevention plan. The deadline was extended to October 1, 2013.
