In addition, a maintenance road will not be constructed adjacent to there re-
forested sections of the RoW, to further reduce impacts.
Impacts on Water
During construction, bare areas along the RoW will be subject to erosion, and
sedimentation of nearby water bodies and watercourses is expected to occur,
although mitigation will be in place to control these effects. Following
reclamation, the slurry pipeline is not expected to cause any negative effects for
surface water, groundwater or water quality that would affect a protected area.
Measures developed to minimize the chance of a pipeline rupture that would
affect adjacent waterways are discussed in Volume I, Appendix 6.1, the slurry
pipeline natural risks report.
Positive Impacts
Through participation and support to conservation initiatives, as noted above,
positive impacts will be realized. A discussion will be required with
administrative committees for the site regarding possible interest to conserve the
pipeline road within the Ramsar site.
