88. Subject to the conditions set out in the second paragraph, sections 13 to 16, 18, 19, 28 to 30 and 34 to 36 apply, with the necessary modifications, to the siting of a trench landfill.
The siting is also subject to the following conditions:(1) the minimum distance between the trench area and any watercourse or body of water must be 150 m;
(2) the minimum distance between the trench area and any catchment installation for surface water or groundwater intended for human consumption must be 500 m. That requirement does not apply if the landfill is not likely to alter the quality of the water;
(3) the bottom of the trenches must be at least 1 m above the rock and the groundwater level. Any lowering of the groundwater level by pumping, draining or otherwise is prohibited.
