CONCLUSION
Feasibility study of the Project as for UGCC has been carried out by CMAI (Singapore)
concerning marketing research together with «SAMSUNG ENGINEERING» and «HYUNDAI
ENGINEERING» (Republic of Korea) concerning process technology and all-factory equipment. This
process technology provides for gas and condensate processing with extracting of valuable
components such as: HDPE, PP, sales gas.
Based on the data provided DEI research was performed taking into account the State
environmental expertise requirements made during DEI project examination.
Results of hydrological and geological engineering survey of UGCC construction area have been
studied thoroughly. In hydrogeological respect the area in question is arid. Ground waters occur at the
depth of over 25.0m, they are strongly mineralized and unsuitable as potable or service water.
Conducted geological engineering survey indicates the necessity of EGE-1 soils removal due to its
macroporosity, subsiding and deformability. EGE-2 soils are also recommended for removal due to their
physical-mechanical properties particularly unevenness of limestones spreading and thickness as well
as marlaceous and argillaceous deposits dilatation. As the foundation soils EGE-3 soils are
recommended for use and EGE-1 and EGE-2 soils are recommended to be changed for artificial soil
and making impervious cushion of loamy soils by compacting.
Domestic waste waters are to be purified at the treatment facilities. Normative clean waters are to
be discharged to the ponds consisting of 5 maps with total area of 12ha for vaporizing.
Method of purified process waste waters disposal to the Out Side Fence Limit of UGCC has not
been worked out yet. Several ways of disposal are being considered:
• utilization for irrigation;
• utilization for bio-ponds;
• filling of depressions or abandoned open cast;
• filling of ponds for vaporizing.
Analysis of degree of the air pollution with total emissions from UGCC and Akchalak CS has
shown that in the area of design UGCC dwelling settlement and existing Akchalak settlement location
maximum concentrations of contaminants in surface layer of the atmosphere will not exceed
established MPCs.
UGCC project implementation will undoubtedly negatively affect environmental complexes being
close to it. In this respect all the technological decisions are to be directed to prevent those negative
effects or minimize them as much as possible. On-site and off-site emissions sources will be equipped
with appropriate analyzers to detect and control contaminants in the atmosphere. Carrying-out of
monitoring will be based on the specially designed program specifying supervision network
arrangement particularities, sampling periodicity, list of components to be control, character of route
supervision as well as the content of reports with a glance at the technological peculiarities of the
Project and relating estimated degree of influence upon the natural environment components.
