5.1.2.5 River Crossing by Transmission Lines and Pipeline
The routes of above ground transmission lines for the proposed power plant will
cross numerous rivers of the piedmont area of the Caucasus. Table 5.4 is
representative of the most significant crossing of large rivers and tributaries.

River Crossings By Transmission Lines
Most of the listed rivers listed above are valuable fishery water reservoirs of grade
1. Fish species are listed in section 2.3.1. Appendix 21 includes the map depicting
location of the listed areas.
The results of this study reveal that both the intensity of the electromagnetic field
and the current density in water under the transmission lines (accounting for
existing standards of minimum conductor sagging above water reservoirs) are
considerably less than hazardous levels for freshwater fish.

Earthwork involving removal of fertile soil and ground excavation can lead to soil
erosion. During precipitation events, this soil can collect in depressions and either
accumulate there or continue on to the Kurchidskaya gully and the Laba river and
cause temporary negative impacts.
To minimize erosion, a number of mechanical controls will be implemented such
as raising the ground in the upper section of the site, provision of a drainage
system for surface water, and planting unvegetated areas with grass and sod.
