Being a socially responsible company, IDGC of Centre gives a major attention to environmental security. The company provides reliable, environmentally friendly power transmission and distribution, and practices an integrated approach to natural resource management.
Environmental policy is conducted in compliance with the Program of Implementing Environmental Policy in 2013 approved by the Company’s Board of Directors. The program encompasses measures of significant ecological impact and aims at minimizing the negative effect of the Company’s activities on the environment.
IN 2013, THE PLANNED EVENTS OF THE PROGRAM OF IMPLEMENTING ENVIRONMENTAL POLICY WERE CARRIED OUT IN ACCORDANCE WITH THE AMOUNT OF THE PROGRAMS FINANCING, AND COMPRISED THE FOLLOWING AREAS:
We control the toxicity of vehicle emissions to prevent it from exceeding the maximum permissible emissions (MPE) limits. If needed, we adjust and replace automobile fuel systems; conduct regular tests in the safety zone, green up and landscape the territories. We also conduct regular sensor monitoring of our complying with the norms associated with the MPE limit.
Sustainable use and protection of water resources
We take laboratory samples of ground water and wastewater to check its microbiological, radiological, and chemical makeup, carry out the cleaning of sewage wells and networks, and take periodical water samples from artesian wells (for laboratory analysis). Moreover, we engage specialized organizations to collect and clean wastewater.
Land conservation and efficient land use
We take measures to reduce harmful effect on the soil: the Company builds temporary storage (depositing) facilities for oil-filled equipment, used oils, scrap metal, and wooden poles.
We set up separate waste storage areas for various danger classes of waste at production sites in special containers. We determine the makeup of waste and its danger class and monitor compliance with MPE and MPD regulations at waste deposition sites. We track the accumulation of highly hazardous materials, such as mercury-filled lamps, and set up areas to receive waste. We mark containers and sign agreements for the waste to be sent to special organizations for consequent processing, recycling, or burial.
To protect the territories against the intrusion of animals we equipped a number of substations with special concrete fences around our substations and installed rodent repellers in 2013.
3.5 thousand birdscarers were installed at the overhead power transmission lines of 35-110 kV to protect birds from being affected by electric current.
Technical steps to support the Program of Implementing the Environmental Policy
In 2013 we carried out the maintenance and repair of the substation equipment, replacing oil switches with vacuum and SF circuit-breakers, overhauling oil-switches and oil equipment at transformer plants, repairing drainage devices, replacing oil-filled bushings for bushings with solid insulation, using self-supported insulated wire, writing off old vehicles and acquiring new ones.
Equipment containing harmful substance of PCBs was written off and dismantled as part of the technical protection measures. PCBs, i.e. polychlorinated biphenyls, are a group of highly dangerous compounds posing a serious threat to man and the environment. In the recent years considerable efforts have been made to control their permissible levels locally and globally. PCB flows are regulated in particular by the Protocol on Persistent Organic Pollutants (POPs) to the 1979 Convention on Long-range Transboundary Air Pollution and the Stockholm Convention on POPs.
PCBs are on the list of the twelve POPs that must be prohibited for use, their production must be stopped, and all stocks must be destroyed. In 2013, IDGC of Centre recycled the 112.26 tons of PCBs.
Replacing oil switches with vacuum circuit-breakers
Unlike oil switches, vacuum circuit-breakers are highly reliable, have better fire safety properties, and are environmentally friendly. The number of vacuum circuit-breakers in use increases each year: in 2013 we replaced 37 oil switches with 35 kV SF circuitbreakers and 504 oil switches with 10 kV vacuum circuit-breakers.
Annually IDGC of Centre conducts the internal environmental audit of the branches, which involves estimating the compliance with the environmental legislation of the Russian Federation and evaluating the implementation of the Company’s environmental policy.
The environmental audit implies check-up of environmental protection documents, examination of various logbooks and contract work. The territory of production departments and their sanitation are examined. Auditors identify the main directions of activities of the branch to reduce the negative impact on the environment, assess the progress in achieving the objectives set and the environmental performance.
Upon the audit completion the auditors issue a conclusion and activities are designed to eliminate the violations detected.
IN 2014 IDGC OF CENTRE WILL AIM AT:
- Introducing new environmentally friendly technologies, materials and equipment, and new working procedures designed as a part of the Company’s technical and environmental policy.
- Carrying out ecological measures planned for 2014 under the ecological policy implementation program for 2014-2018.
- Conducting environmental audit.
- Industrial ecological control.
- Timely obtaining of the necessary ecological approvals.
- Meeting all the conditions of using underground resources stipulated in the license.
- Timely delivery of hazard class l-5 waste for utilization and burial.
- Monitoring compliance with the requirements of temporary accumulation of production waste and consumption residue.
- Taking technical measures to prevent the death of birds along overhead power lines.
- Taking measures to prevent soil contamination with oil products.
- Waste management and environmental safety when handling equipment and waste containing PCBs.
