112. Removable structures whose supports are located outside the upper limit of the bank must be removed from the watercourse not later than 6 months after their installation in felling or hauling trails or not later than 3 years after their installation in a winter road or a road that will be closed permanently.
The types of removable structures described in the second paragraph of section 111 must be removed from the watercourse at the end of their use, not later than 31 March following their installation or before spring freshet if it occurs before that date, so as to prevent the carrying of sediments into the watercourse and the creation of an ice jam.
Where log mats that are interconnected were used to stabilize the banks, they must be stable and left in place. The granular materials used for the roadway surface near the removable structures that have been removed must be recovered over a distance of at least 20 m, measured from the upper limit of the bank and they must be deposited further than that distance.
