Chapter V – Roads, sandpits and forest infrastructures
Division III – Bridge, culverts, removable structures and rudimentary structures
§2. Prohibited construction, improvement or repair
Section 90
The construction, improvement or repair of a bridge or a culvert or the installation of a removable structure in a salmonid watercourse must be carried out at all times by using techniques that allow to limit the carrying of sediments outside the work area and thus preserve the attributes of the habitats present such as spawning grounds. The techniques must be adapted to the conditions of the site. The techniques include the drying of the work area, the performance of the work during the period of minimum flow and the installation of a sediment confinement curtain.
The first paragraph does not apply where all the construction, improvement or repair work of a bridge or a culvert or the installation work of a removable structure are done outside the upper limit of the bank.
