Executive Summary 1.1 Policy, Legal, and Administrative Framework The Law on Environmental Protection requires that an Environmental Impact Assessment (EIA) has to be prepared for a planned activity. The Law on Ecological Expert’s Review defines the activities that require EIA and states ‘Any new construction, reconstruction, expansion or re- equipment of operating economic entities or other entities which are likely to have impacts on the environment’. Consequently, for the ADB - TA-7704 (KGZ) Power Sector Rehabilitation Project an Environmental Impact Assessment has to be conducted. The key government institution responsible for the establishment and implementation of environmental policy and management in the Kyrgyz Republic is the State Agency on Environmental Protection and Forestry (SAEPF). Therefore the EIA report has to be reviewed by the Department of Ecological Expertise within this authority. SAEPF is then responsible for issuing environmental permits for infrastructural projects. The Agency is directly ranked under the government and has the status of a ministry. The Agency located at Bishkek is responsible for all nationwide projects of national importance. Another (newly established) environment-related authority in the country is State Inspectorate for Environmental and Technical Safety that is authorized to inspect and control state profile bodies and their subdivisions on fulfillment of environmental and technical requirements in industrial and other relevant fields. 1.2 Description of the Project Project Location and General Situation The backbone of Kyrgyz power generation is the Naryn River with its several hydropower plants Kambarata 2, Toktogul, Kurpsai, Tash-Kumur, Shamaldy-Say and Uch Kurgan. Electricity demand in Kyrgyz Republic is highly seasonal with two thirds of domestic consumption taking place in autumn and winter. Although electricity generation capacity has nearly doubled since the Soviet era, load shedding is frequent especially in the winter when hydropower output is limited due to low river discharge, while cuts arise from problems due to technical failures in the outdated generating equipment. Hydroelectric generation from the Naryn Cascade is central to the present and future economic development of the Kyrgyz Republic also with view on an electric power generation and transmission system regionally managed between the Central Asian Countries in future. 4864P15/FICHT-8320034-v2 1-1 However, the future security of this capability is in some doubt because of the age of most of these facilities. They are over 50 years old, obsolete and many spare parts are no longer available. Therefore, the rehabilitation of Toktogul HPP being part of the Naryn cascade is of paramount importance. Category of the Project Following ‘Environmental Considerations in ADB Operations’ of September 2006, the Project can be considered to be a Category B project requiring an Initial Environmental Assessment (IEE). The Project will not require an acquisition of land and resettlement activities will not become necessary at all. There is no protected area located nearby and ecologically sensitive habitats will not be affected. All activities will take place within the properties of the existing HPP facilities belonging to Joint Stock Company Electric Power Plants. Implementation Schedule It is foreseen to finalize the technical feasibility of the Project until middle of 2012. It is intended to prepare the tender documents until mid of 2012 and end of 2012 the construction contractor should be determined. The rehabilitation contract itself will probably start in the course of 2013. Description of the Project and possible Impacts At HPP Toktogul following measures are foreseen: • rehabilitation of the periphery of the generators requiring the temporary shutdown of the generator actually worked on; • replacement of four oil operated generator circuit breakers by state-of- the-art SF6 circuit breakers; • replacement of four oil-filled 500 kV cables of a length of approx.
