2 PROJECT DESCRIPTION AND CURRENT ACTIVITIES
2.1 Project Description
4. The Northwest Region Power Transmission Line Project (the Project) is located in the south-western provinces of Karakalpakstan and Khorezm of the Republic of Uzbekistan, near the border of Turkmenistan.
5. The new transmission line will transmit power from Takhiatash Thermal Power Plant and increase reliability of power supply for the Khorezm province and Karakalpakstan in the northwestern part of Uzbekistan benefiting at least 3 million population.
6. The objectives of the Project are: (i) increase energy security through the diversification and expansion of energy supply routes; (ii) improve power supply reliability in the country and region; (iii) reduce transmission losses; and (iv) improve operational efficiency of the power sector.
7. The first part of the TL route passes across the territories of Hojeyli, Nukus, Karauzyak, Amudarya and Beruniy districts of the Republic of Karakalpakstan, and Urgench and Yangibazar districts of the Khorezm region of the Republic of Uzbekistan. The second part of the projected TL route is laid across territories of Urgench, Hanka, Yangiarik, Bagat and Hazarasp districts of the Khorezm region and the Turtkul district of the Republic of Karakalpakstan.
8. Construction activities of above mentioned facilitates will be done and financially covered by Uzbekenergo. Procurement of the equipment and goods will be performed under ADB loan. The total cost of the project: 258,5mln. USD. Feasibility study approved by Decree of the President of Uzbekistan No. 2541 on 06 June 2016.
9. The Project consists of the following main components:
i. Construction of 363,8 km of 220 kV single-circuit overhead transmission line: between Takhiatash TPP and 220 kV Khorezm substation (197,7 km) and between Khorezm and V1 node (166,1 km);
ii. Expansion/Rehabilitation/Construction of 2 Substations. Including (a) rehabilitation and expansion of 220/110 kV Khorezm SS; and (b) construction of an open switchyard 220 kV of a new 500/220 kV SS Sarymay near V-1 node (Sarymay settlement); and iii. Support for Institutional Development, Capacity Building, and Project

4 RESULTS OF ENVIRONMENTAL MONITORING
4.1 Overview of Monitoring Conducted during Current Period
39. Environmental monitoring will be started immediately after the commencement of the civil works by the Contractor. 40. During the ADB Mission monitoring of environmental safeguards compliance conducted on 14th March 2018 the following findings have been revealed: • Hazardous Waste Management: The Mission agreed that temporary storage for hazardous waste should be prepared immediately before dismantling the old equipment. Disposal of scrap metal and old batteries should be carried out under contracts with specialized organizations. Disposal procedures with the supporting documents should be kept in special project files for records. Status: During this reporting period there was no action yet as there is no contract with CC.
• PCB Management: The Mission reminded that there is a high risk of PCB contamination from releasing oils from the old transformers and other oil-based equipment. It is required that PCB management plan should be developed as a SEMP, and PCB analysis should be conducted before releasing the oil from the equipment. International environment consultant of Fichtner GmbH & Co is requested to provide option for PCB analysis and validation of PCB test if conducted in UZB. Status: PMU is Informed and they are planning the action.
