From hydroelectric power and transmission lines
The hydroelectric power plants for the smelter plant will be in areas with a very low population density. The impacts to be studied are therefore focused on nature, cultural heritage and wildlife.
Hydroelectric power plants with dams contribute to changing flows, water composition and water levels in the reservoir lakes and rivers, through which the water has until now flowed towards the sea. Specifically, reindeer, muskox and trout stocks will be studied and their migratory and reproductive patterns, together with the general biodiversity in freshwater areas at the reservoirs. The purely physical changes in water composition and sedimentation are also part of the studies.
The studies are relevant to hunters and fishermen, as well as recreational hunters. Society’s knowledge is therefore involved as part of the studies. At the same time, there will be studies on the presence of cultural sites in the area through archaeological studies. By increasing the water level in the reservoir lakes, there must be a prior excavation of the most important cultural sites, so that the historical knowledge that the sites can contribute is not lost.
A number of the same studies are applicable to transmission lines, where the primary impact will be in the construction phase. It is particularly the impact on reindeer, as well as archaeological studies carried out to study the possible impact of the transmission lines.
