transport operation. The main components will be fuel combustion products in engines, and
also inorganic dust during pipelines laying, trenching and excavation and etc. it is necessary
to note, that impact on atmospheric air during construction will have short-term character,
that practically will not affect background level of atmospheric pollution.
According to intensity and impact level per time unit and unit of area the impact will
be moderated and subject to inversion phenomenon the level of APP will low increase.
As construction will be in the limited areas, dimensional coverage of impact will be
limited by the necessary area and will have local character.
Construction of pipelines will have temporary impact on soil and vegetation, upon
termination of construction there will be executed restoration of the disturbed lands.
Impact on surface waters has indirect character and is connected with withdrawal of
water resources for industrial and drinking needs. Impact duration is the period of the
designed constructions operation. Temporary dynamics of water withdrawal will be
constant for fresh water.
Distribution area, in case of sewage disposal to ponds-evaporators, is limited by the
area of ponds-evaporators.
Soils of investigated region concern to the main objects of impact. During this time
intensity of impact is low, has the periodic character increasing during emergency
emissions.
Impact duration will not change, as this volume depends on time of the constructions
operation. Impact will be continuous. Distribution areas will not extent. Impact character
remains direct, as before.
According to calculations of atmospheric pollution and operational experience of
similar manufactures, it is possible to state, that the enterprise personnel will breathe air
which quality corresponds to sanitary norms in the working areas, confirmed by Ministry of
Health of the Republic of Uzbekistan.
The soils of the investigated site of works and adjacent territories represent a zone of
natural not high fertility (it is necessary irrigation). Small humus content does not allow
developing to high vegetation types. Wind erosion and total amount of dusty particles are
one of the reasons of soil degradation. Proceeding from the analysis of soil cover condition
in the zone of object impact, it is possible to draw a conclusion:
- object construction is carried out on the lands not convenient for
agricultural crops.
- main object impact is connected with additional disturbance of
soils structure throughout gas pipeline route.
In view of remoteness, surface waters are not objects of impact (only withdrawal for
water supply).
