B.2.2.2. SEA
Rogozin, another important landscape, is an extraordinary combination of soil
and water bodies typical for the Neretva. This zone has been disturbed by
construction works but some landscape and ambiance features should be
preserved.
Several monuments can be found in the immediate surroundings. On the
Kozjak and Sladinac there are antique locations, in Rogotin are three
protected complexes and a church not distant from the Bacina Lakes, St.
Luca’s church and medieval localities are near Pucevo.
The construction of the container terminal in the Port of Ploce, located in the
center of the port, does not increase the impacts upon its environment.
The borders of the dock area of the Port of Ploce, which is located next
to an important landscape, are strictly defined in order to best conserve
the protected parts of the environment.
The dock construction will lie on concrete columns – pilots. During the
utilization phase, impacts from urban wastewater and industrial waters, oil and
its derivates as well as water turbidity and pollution with solid waste in case of
emergency are most likely.
Increased amounts of phosphorus and nitrogen (urban wastewaters) cause
the growth of phytoplankton and combined with silt this increases the
seawater turbidity. Oil contamination generated by the marine transport is
limited to the supralitoral and mediolitoral zone. Sediments of masut, oil and
silt prevent a normal communication between the concrete organisms and the
environment, which leads to the extinction of many species.
Because of the surface size and the distance from the natural shore, the
section under the quay will be left in complete darkness. Wearing out of the
organisms whose life conditions will be changed as well as the suspended
organic particles load in the water column will cause increased oxygen
consumption and most probably anoxia.
Weaker currents along the quay would impede the oxygen renewal, in
particular over the summer months when also the vertical water exchange is
insignificant (thermocline). Solid pollutants should have no impact on the sea
environment, except for the esthetical one.
The construction of the container terminal will entail an increase of the basin
depth, because the sediments would be excavated to a certain depth. The
removal would not include only the surface layer but all the existing organisms
as well. What would be left is the pure azoic silt, at least in macrobenthic
terms.
Considering the planned operation, it is estimated with high level of certainty
that it will have no additional negative impacts upon the environment. The
construction would not imply any new activity in the aquatorium between Quay
5 and Quay 7 in addition to the depth and the navigation path maintenance
done so far.
