Annual report 2010

JSC IDGC Holding. Annual Report 2010Environmental ProtectionThe peculiarities of operations performed by distributiongrid companies do not involve any significantadverse environmental impact, capable ofcausing irreversible changes or environmental disasters.The requirements for electrical installationswith regard to environmental safety, providing forground protection against petroleum products(installation of oil-drip and drainage facilitiesunder oil-filled equipment more than 1 tonne ofoil), the protection of people and the animal worldagainst the impact of current-carrying parts(unavailability of unauthorized touch, penetration),etc are specified during the design phases.The principal areas of SDCs’ protecting the environmentfrom the adverse impact of their productionactivities are specified in the Programs ofEnvironmental Policy Implementation for2007–2009 (2008–2010) developed by eachregional and interregional grid company pursuantto Minutes of the Meeting of the ManagementBoard of RAO UES of Russia No. 1538pr/2 ofSeptember 25, 2006, and approved by their boardsof directors.In 2010, IDGC Holding worked in the followingareas of environmental protection: air protection,water protection and conservation, land protectionand conservation.Air protection included controlling the harmfulcontent of vehicle exhaust emissions to preventexcess values, adjusting vehicle fuel systems,replacing gasoline systems with gas-powered systems.The fiscal year witnessed activities aimed atimproving landscaping land. Some branches ofJSC IDGC Holding’s SDCs worked to develop andjustify sanitary protection zones where the keyadverse factor was that noise was generated bythe cooling systems of supply transformers if 35kV and above substations located near housingareas and that exhaust gas accumulated at vehiclefacilities located near housing areas.In general, in 2010, air emissions decreased versus2009 due to the air protection work performed.Water protection and conservation was connectedwith exercising compliance control with respectto maximum allowable concentrations in effluentsin the household plumbing and storm sewage system,repairing drainage systems, improving drainsewage systems, controlling the condition of thetreatment facilities of vehicle-washing plants andinstalling new filters and chemical agents atclosed-water-cycle vehicle-washing plants.Land protection and conservation was connectedwith disposing of production waste, transferringproduction waste to specialist organizations forsubsequent processing and dumping, setting limitson waste disposal, and providing equipment fortemporary waste storage places. In 2010, IDGCHolding generated 78,714 tonnes of waste; theyear-end balance was 2,462 tonnes. The fiscalyear saw limited soil reclamation. 81.12 out of the82.4 hectares of land damaged in 2010 were recultivated.Despite the inflation growth, in 2010, theCompany managed to reduce slightly its chargesfor permissible and above-standard emissions,discharges and waste disposals. The amount offive-fold charges for emissions, discharges andwaste disposals was reduced owing to the developmentand approval of permissive documentationby most SDCs of the Holding Company.The fee for negative environmental impact wentdown by RUB 3,415.3 thousand versus 2009 toRUB 52,352 thousand.In 2010, the following activities were performedto protect the environment against the adverseeffects of production operations:— use of self-supporting insulated wire in newconstruction, rehabilitation, technicalupgrading of high-voltage lines of up to1,000 V, construction of 6-20 kV armoredoverhead lines to reduce cutover area andprotect birds against electric shock;— the installation of noise screens at 110 kVsubstations allows bringing noise level indwelling zones down to the threshold level inaccordance with the requirements of SanitaryRegulations and Standards;— replacement of oil and low-oil circuit breakerswith vacuum circuit breakers to preventsoil contamination with petroleum products;150
