Environmental Safety of Gas Transmission System

Company’s activities in the sector of environmental safety are performed in compliance with the environmental legislation of the Republic of Kazakhstan and generally accepted international principles, implying the need to:

• ensure sustainable and environmentally-friendly economic development;
• perform protective and environmentally supportive actions;
• introduce energy saving technologies;
• observe the right of people to live in a healthy natural environment.

In 2007, Intergas Central Asia was certified under the international standards DIN ISO 14000-2004 for Environmental Management. The acting corporate environmental policy reflects new trends of the international practice, intention to operate in compliance with the global ecological standards, and to widely address environmental issues while taking decisions on operational and financial problems.

The corporate environmental policy pursues the aim to ensure environmental safety of the industrial operations by equal balancing of economic, social and environmental values.

The main purpose of the Company in the ecological sphere is a staged reduction of the negative environmental impact. The impact of the Company’s industrial operations on the environment is monitored and managed by the own staff of the established laboratory for Industrial Environmental Monitoring (IEM) specially equipped with most advanced testing devices and instrumentation.

Minimization of negative effects that industrial facilities produce on the environment is achieved through the improvement of the technical features of the transmission infrastructure, its technical modernization including replacement of aged equipment and pipelines with the new ones, and use of state of the art leakage detection devices along the main gas pipelines and gas concentration detection systems in the buildings with compressor units.

To accomplish the above objectives, the following actions are taken:

• Reduction of air polluting emissions:
  • reduction and eradication of gas leakage and losses during of repairs, pigging and cleaning works at the pipeline sections of the MGP facilities;
  • reduction of compressor machinery emissions resulting from due repair and upgrading;
• Reduction of water effluent pollutants:
  • construction of effluent water treatment facilities;
  • construction of reservoir water treatment plant at underground gas storages;
  • construction of water circulation piping networks;
• Protection of soil and sub-surface, waste utilization and burial of wastes:
  • improvement of technical performance parameters of underground gas storages utilization;
  • liquidation of open pit tanks and construction of closed type condensate gathering containers for gathering and storing of gas condensate emulsion slurry along the entire route of the gas pipelines;
  • construction of background observation wells around condensate gathering tanks and underground liquid fuel storage tanks;
  • timely removal of industrial and consumers’ wastes for further utilization.
