Most rain falls in April - 18 mm, representing 16% of the annual amount, the
least rainfall in July, August and September. Maximum daily rainfall of 66 mm.
Snow cover does not exceed 17 cm, number of days with snow cover is 27.
Number of days with dust storms and dust ground winds for the year equal to 57.
Number of hours of thunderstorms per year - 9.
According to the zoning of the territory of Uzbekistan on the climatic
characteristics, this area belongs to a region of wind pressure with the normative
values of 0.38 kPa and an area for snow loads with a normative value of 0.5 kPa.
Regulatory wall thickness of ice with repeatability once every 5 years is 15 mm,
once in 10 years - 20 mm.
Thus, the location of the major sources of harmful air emissions may contribute
to the formation of elevated levels of air pollution in all wind directions. Nevertheless,
in every season meteorological factors may also influence the activation of the
scattering power of the atmosphere, excluding the formation of intense sources of
pollution.
The main sources of environmental impact in the area of construction of MCC
Akchalak and pipelines for transporting products of the complex are: objects
Akchalak COP and the main gas pipeline Central Asia - Center, CPF Akchalak,
Kungradskiy Soda Plant, as well as railways and roads Kungrad - Beyneu and
residential village.
However, these objects are not large and are located far away from the
construction site, almost industrial impact on the components of the environment in
the GCC do not have.
In terms of air pollution largest and closest sources are the sources of the
compressor station Akchalak at the site to which there are four compressor plant, each
equipped with a fleet of SBS. The main sources of air emissions is gas-compressor
units such as the GT-25I, SCC-10-4, I-6, 3 in quantities of 10 pieces, by which the
atmospheric air enters the combustion products of fuel gas in gas-turbine drives.
On-site cleaning of the gas compressor in all the shops are set cyclones (22 pcs.)
That are sources of emissions of hydrocarbons (as methane).
Methane into the atmosphere also occurs at start-up operations, cold cranking,
stop and unloading units, purging pulse and fuel reservoirs. Emissions into the
