Description of implemented and transitioning to the next period investment projects
To increase the supply of electric and thermal energy from the energy source CHP-3 to meet the
needs of existing and prospective customers, as well as improving the reliability of power supply,
steam supply and heat supply the project “Reconstruction of the Petropavlovsk CHP-2, including
replacement of turbine number 1” was developed with the introduction of modern automated
process control system (PCS), the planned completion date of construction - 2015. Reconstruction
of K-63-90 TA turbine unit number 1 in place of dismantled T-42-90 / 1.2 LMZ turbine allows to:
 Increase the heat load of the renovated and modernized turbine in order to increase technical and
economic indicators of the turbine;
 Increase the production of electricity at the most economical heating cycle on the basis of heat
supply from the heating selection of the turbine for external customers and for their own needs;
 Increase the installed electrical capacity of TPP-2 for increase power generation in order to
supply it to the regional / wholesale electricity markets, to reduce the gross heat rate depending
on the mode of operation of turbine, and, respectively, to reduce the specific consumption of
equivalent fuel, which ultimately helps to reduce emissions of harmful substances in the
atmosphere of the city.
In order to prevent the ash dump surface dusting at worked-out section the technical restoration of
ash dump №3 PHPP-2 of “SEVKAZENERGO” JSC is provided, which means creating protective
layer by dint of sandy clay, planning grass, access ramp arrangement. Filled section is to be covered
by protective quarry-sandy-clay layer of 0.5 m-thickness, laced with 10%-vegetable soil in upper
2
layer of 0.2 m, which complies with 1.04-14-2003 sanitary regulations and norms of the Republic
of Kazakhstan “Toxic industrial wastes deactivation and burial areas”. Planned term reclamation of
ash dump №3 is from 2015 to 2020. The project also includes a set of measures to reduce the
impact of reclamation of ash dump TPP-3 on the environment: the use of the developed land,
moisturizing territory and roads, shelter tents dump truck for transportation of loose and dusty
materials.
The works on the reconstruction of a generating boiler number 8 are completed. The purpose of
reconstruction of boiler number 8 made by Barnaul Boiler Plant is not only to reduce the deficit of
stem capacity by increasing it up to 270 t / h, but also the ability to provide reliable operation of the
boiler equipment in a wide range of loads with increased environmental and economic performance
of work. In line with the project, the existing furnace is replaced by a gas-tight furnace. Stiffness
and strength of the walls of the furnace is provided by horizontal stiffness belts mounted on the
perimeter. Boiler drum is left with full replacement of separation devices inside the drum. To ensure
regulatory steam velocity at elevated boiler load the steam collector is increased in diameter and the
main steam valve is provided with a larger nominal bore diameter of 250 mm, instead of the valve
with a diameter of 225. It is provided to use existing channels of hydraulic ash for transfer of the
pulp-slag from the boiler number 8 in the Ash-pump. The boiler is provided for staged combustion
of fuel, thereby reducing the excess air ratio and reducing the amount of nitrogen oxide formation.
In addition, when using a solid fuel boiler application of bottom air nozzles helps to prevent
slagging and reduces the carbon failure.
Implementation of the investment activities on the project “Reconstruction of the Petropavlovsk
TPP-2 with the replacement of boiler unit number 8” is aimed at reducing emissions of NOx,
increasing efficiency and reliability. Due to the reconstruction of furnace and boiler burners the
atmospheric emission of nitrogen oxides will be reduced to value guaranteed by the manufacturer
(450 mg / Nm3). Similar reconstruction was carried out in 2012 on a boiler at station number 7of
PCHP of “SEVKAZENERGO” JSC.
III.
Environmental impact assessment
Implementation of projects is of great socio-economic value determined by the scale and proportion
of electricity and heat production in North-Kazakhstan region. Technical solutions adopted in the
implementation of investment projects suggest the following conclusions on the impact of the
natural and socio-economic environment:
1. Atmospheric air
Every project includes measures to prevent (reduce) emissions into the atmosphere.
3
The main sources of impact on the environment during the construction and installation work on
the reconstruction of turbine and boiler are: motors of trucks and construction machinery,
construction machinery refueling by bowser, suction of soil, gravel, sand and gravel and sand,
welding and gas cutting works, painting and waterproofing, asphalt paving, etc. Direct operation of
the turbine units is not accompanied by the emission of pollutants into the atmosphere. The increase
of emissions from fuel combustion at the implementation of this project is not provided, since the
capacity of boilers, and time consumption of coal in the whole plant is not changed. Boiler steam
output remains is unchanged. Under the current project “Environmental impact assessment” to
PCHP-2 of “SEVKAZENERGO” JSC the maximum fuel consumption for the whole company is
designed for nominal operation of boilers. Pollutant emissions for the whole plant after
commissioning of turbine units will not exceed the standards established for the PCHP-2 of
“SEVKAZENERGO” JSC. Calculations of dissemination for the period of the equipment
reconstruction and operation proved that surface concentrations of all ingredients to not exceed 1
maximum permissible concentration on the company's sanitary protective zone boundary.
2. Water resources
Ongoing projects include measures to prevent and reduce the impact on water resources.
With the purpose of maintaining necessary hydrological regime of the cooling pond, the Company
executes regular cleaning of the lake from sludge and bottom deposits. In compliance with the
requirements of “Rules of operation of water facilities, located directly at water objects” dated
30.01.2012 # 171. In September 2013 the Company conducted commission periodical technical
review of hydro technical water facilities: on-shore pumping station, discharge and influent
channels of CHP-2, central pumping station, located directly at water objects of Ishim river and
Beloye lake.
The Company performed the systematic replacement of the obsolete water-oil coolers with the
worked out economic life for the modern ones. Stations Number 6, 7, 3 are equipped with this
equipment. This measures prevent the used turbine oil and petroleum products from entering into
drain of Beloye lake cooling pond.
The modal network of wells and observation over the stage of the groundwater are provided for
groundwater monitoring.
According to the project of reconstruction of turbine units the water for cooling will be supplied
from the existing recycling system of technical water supply. Accounting for the consumption of
fresh water for feeding water recycling system provided by the existing flow meters. Water
consumption in the period of reconstruction and operation of the designed facility will not result in
exceeding the permitted limit of water intake. There are no any water surface bodies in the vicinity
of the location of the proposed facility, so a direct impact on them is eliminated.
The probability of groundwater contamination is virtually absent, as underground water table is
4
deep enough.
In order to prevent impact on groundwater during the implementation of all projects the measures
are provided in order to prevent penetration into the soil and groundwater of mastics, solvents, fuels
and lubricants used in the construction and operation of construction equipment and vehicles, to
prevent the organization of irregular garbage and construction waste dumps. Under the terms of the
construction the impact on groundwater pollution is not expected during project implementation.
In order to protect the environment and reduce the impact of the ash dump of PCHP on the
hydrosphere, to protect the surface and groundwater from pollution and to reduce the consumption
of fresh water the revolving cycle of water supply system GMI is provided.
3. The Soil. Waste
The project provides measures to prevent and reduce the impact on the soil.
Projected turbine and boiler are placed within the existing land allotment enterprises, removal of
topsoil is not provided, since the reconstruction sites are located in the existing main building of the
enterprise.
With the purpose of reducing negative impact of wastes on environment, the Company carefully
organizes collection, storage, and disposal of wastes to the sites of its disposal. For prevention of
pollution by production and consumption wastes, the Company provided the following actions:



arrangement of the site with containers;
collection of communal and production wastes is executed into different containers, and wastes are
disposed regularly;
repair of vehicles is executed only in a specialized territory, which prevents pollution of soil by the
wastes and oil products.
Wastes of all kinds, produced in the course of reconstruction, are transferred to respective
enterprises under agreements for their allocation or treatment. The planned improvement works and
landscaping businesses are fully implemented.
4. Subsoil
No new lands are withdrawn for the projects' purposes, which excluded:
 building on areas of commercial mineral occurrence;

violation of rare geological outcrops, mineral buildups and subsoil sites, proclaimed as
reservation parks, natural, history, and culture monuments.
5. Flora and fauna
Analysis of flora and fauna of the territories, which were in operation for a long period of time,
demonstrates that due to the long-term man-made burden, the structures of plant and animal life
simplify, which is firstly related to the factor of displacement. In this regard, the reconstruction of
the boiler and turbine will not lead to a violation of the existing structures of tehnic landscape, flora
and fauna.
5
There are no rare plants and plants from the Red Book in the area of reclamation of ash dump №3.
6. Physical impact on the environment
Every project involves activities aimed at reducing the physical impact on the environment.
Turbo facilities and accompanying equipment being installed cause the following physical impact:
noise, vibrations, thermal and electromagnetic emissions. In order to reduce physical impact the
projects provide the following activities are to be implemented:
 usage of modern facilities producing noise and vibrations which don’t exceed permissible
allowance;
 construction of independent equipment understructures;
 covering of the turbines cylinders, high-temperature equipment and pipelines by special thermal
acoustic evaporate insulation, allocating equipment in special rooms and enclosures (cages,
mantles);
 using silencing heads, flexible connections (clutches), elastic gaskets, flexible supports and
suspensions for the equipment being installed.
Physical impact from the objects being reconstructed is eliminated through the above mentioned
activities within the main building and site. Upon the engineered objects being put in operation the
level of physical impact will not increase for the whole enterprise in general, as old-fashioned
equipment will be replaced by turbo generators.
7. Socio-economic environment
In every project the evaluation of environmental risks and risks to health of the local population,
assessment of the impact on the socio-economic sphere are performed.
Directly reconstruction of equipment of PCHP “SEVKAZENERGO” JSC does not have any impact
on the socio-economic conditions of the local population and has no change in the characteristics of
its work. Implementation of investment projects on the reconstruction of equipment of PCHP will
improve the sanitary-epidemiological status of the station area by reducing the total emissions of
inorganic dust in the atmosphere. At the same time, environmental information of the
‘SEVKAZENERGO” JSC was published 2 times in Kazakhstan print media:
 according to the request from the Center for Sustainable Production and Consumption in April
2014, information about “SEVKAZENERGO” JSC was officially published in print media
