The sizes of the ground areas withdrawn in short-term and long-term rent correspond
to working regulations. The areas of the lands necessary for building of designed
constructions will be corrected on the further design stages.
Mechanical impact connected with damage of the soil-vegetable cover during earth and
construction-and-assembling works execution and relief leveling reoperation
The leveling operation of designed industrial areas and access roads bed is executed
taking into account existing lay of land, geological and hydrological features of the
construction territory.
Impact on soil-vegetable cover during laying of out of area communications will
have short-term character – during construction only. There is damage of the soil surface
layer on depth up to 2m during preparation of zone of temporary allotment under pipeline
laying.
After carrying out construction-and-assembling and earth works there are taken out
construction waste (the rests of pipes, insulating material, etc.) from construction zone
(territory of short-term rent), all temporary installations, and there is spent technical and
biological restoration. Then, these ground areas will return to former owners in condition
suitable for their economic use.
One of the main measures directed on protection of the soil-vegetable cover is
technical and biological restoration of the ground areas dislocated during construction-andassembling
works execution.
The technical stage of restoration includes work package for removal and restoration
of the soil fertile layer and preparation of the construction zone territory (the ground areas of
short-term rent) for carrying out biological stage of restoration.
Proceeding from soil conditions of work production area, there is subject to stripping
the fertile, most active in the biological relation and used in agricultural production layer of
soil by thickness of 30.0sm.
Biological restoration is carried out after technical stage and directed to restoration of
soil physical and biological characteristics, improvement of structure and water-air regime
of plough-layer.
Unsystematic travel of motor transport and the construction technique, and also
planning works execution during leveling operation under arrangement of areal objects can
cause serious damages of the soil-vegetable cover. It is possible considerable activization of
deflation processes in the territory of the broken sandy massifs.
Analysis of the damages occurring during construction on objects-analogues shows,
that during construction work execution without nature conservative measures (absence of
access roads, work out of allotment zone) the area of damages in 3-5 times exceeds the
permissible allotment areas.
Soil-vegetable cover chemical pollution during objects construction and operation
It is possible soil cover chemical pollution:
