4 ANALYSIS OF ENVIRONMENTAL IMPACT OF THE
DESIGN OBJECTS
This chapter includes characteristics of sources of environmental impact proceeding
from the analysis of possible technological and technical decisions on designing of Surgil
GCF construction and gas transport to Akchalak GCC, and also the characteristic of impact
types connected with adding of pollutants to environment and withdrawal of natural
resources, parameters of anthropogenic impact and the main objects of impact in the course
of construction and operation of designed objects. There will be impact on the following
components of environment during project realization:
- atmospheric air.
- soils and vegetation.
- underground waters.
From the general project it is possible to allocate pollution sources by the following
production string:
- wells construction;
- construction and operation of loops, GGS, collectors;
- construction and operation of CGTU;
- construction and operation of pipelines on GCC.
There is carried out analysis of impact of the emissions, dumps, waste, and
withdrawal of land resources during construction and operation on the basis of design
decisions.
4.1 IMPACT ON ATMOSPGERE AIR, AQUATIC ENVIRONMENT, LAND
RESOURCES AND FLORA DURING CONSTRUCTION
During construction of designed buildings, constructions and pipelines the
atmospheric air will be exposed to impact by emissions of pollutants from internal
combustion engines (ICE), from road building technique and motor transport, and also from
welding machines and painting units.
There will concern to the road building technique and motor transport used in the
construction of designed objects: excavators, bulldozers, motor graders, pneumatic-tyred
road roller, pneumowheel, rubber-tire, caterpillar and automobile cranes, cranes and pipestringing
machines, moving welding machines and compressors, inclined-axis mixers and
auto cement mixers, dump trucks, pipe trucks, tractors, onboard cars, tank truck.
