PFS “Surgil field complex costruction with valuable
components retrieval”
There is not supposed considerable impact during object functioning on other
components of environment (water, flora, fauna) during performance of the measures
offered by the project for prevention or softening of the revealed possible adverse effects.
Construction and operation process of planned object can also change of social and
economic conditions of the vital activity of the population of nearby settlements.
Offered design decisions are confirmation of ecological efficiency of project
realization connected with improvement of the environmental conditions or its separate
components, and also are directed to the prevention of ecological risks occurrence.
The population living at distance from industrial objects will not feel special change
because of local character of the given project operation.
Sewage waters do not render direct impact on water objects. There is possible
underground waters pollution as a result of a water filtration in the ponds-evaporators,
however, during long operation of ponds their bottom has become covered by deposit layer
interfering with filtration processes. Also, filtration process is interfered with structure of
the underground waters having high density at the expense of high mineralization. Absence
of organic pollution in the analysis of existing observation wells waters confirms the
assumption of absence of underground waters pollution.
Proceeding from the aforesaid, integrated assessment of the environmental condition
in the region of planned construction has shown following results.
Impact on atmosphere will rather increase, especially by nitrogen oxides, however, in
whole, functioning of designed object practically will not change the established level of
atmospheric air pollution.
Impact on soil and vegetation will be expressed in violation of integrity of the soilvegetable
cover during construction works execution and gas pipeline laying. Possibility of
emergency condensate spills is not excluded during pipeline leakage. After execution of
construction works on pipelines laying, all lands which have been allotted for temporary
use, will be restored. There are build into estimate corresponding means for restoration. The
emergency spills, which probability is extremely small in view of pipelines embodiment, do
not represent considerable danger to environment (soils, water streams, atmospheric air).
Failures are subject to the immediate liquidation, the polluted ground is subject to
transportation, the failure site is exposed full restoration. Thus, it is possible to state, that
design decisions provide the careful treatment of grounds and soils, provide conservation of
their agricultural qualities.
After restoration processes the vegetation during short time is completely restored.
Accordingly, animals after construction termination have possibility to return to former
inhabitation. Planned construction does not establish obstacles to migration of animals.
The landscape will keep its modern appearance (will change not considerably).
Considering the above-stated, health impact of the maintenance stuff and population
through the way of pipelines routes will practically not be felt.
