89. Sections 37, 39, 40, 40.1, 43 to 49, 52 to 55, 57 to 59, 63 to 66 and 69 to 71 apply to the operation of a trench landfill, with the necessary modifications, in particular as follows: the quantity of residual materials referred to in subparagraph 4 of the first paragraph of section 39 may be expressed in volume, and the maximum distance authorized by subparagraph 2 of the third paragraph of section 65 for the installation of groundwater quality monitoring wells is extended to 300 m from the trench area.
The provisions of sections 63, 65 and 66 do not apply to a trench landfill that is completely sited on a mine tailings heap if the monitoring and supervision measures prescribed by those sections cannot be implemented due to physical constraints inherent to the heap. In that case, the operator must see to the implementation of substitution measures that, in addition to being better adapted to those constraints, allow water monitoring and supervision as close as possible to those prescribed by sections 63, 65 and 66.
