52. Results of analysis showed that concentration does not exceed national standards on
measured 7 indicators.
53. There are no detailed numerical requirements established by IFC’s legislation to
ambient water quality. The requirements are: 1) discharges of process wastewater, sanitary
wastewater, wastewater from utility operations or storm water to surface water should not
result in contaminant concentrations in excess of local ambient water quality criteria or, in the
absence of local criteria, other sources of ambient water quality; 2) temperature of wastewater
prior to discharge does not result in an increase greater than 3°C of ambient temperature at
the edge of a scientifically established mixing zone which takes into account ambient water
quality, receiving water use and assimilative capacity among other considerations.
54. National standards for vibration level in residential houses are provided in Sanitarian
Norms and Rules (SNR) № 0146-04 “Design of the living houses in climatic conditions of
Uzbekistan”. For living houses the standards is 67 dB for night time and 72 dB for day time
with frequency in 37 and 61 Hz and for night time is 67 dB.

6 GOOD PRACTICE AND OPPORTUNITY FOR IMPROVEMENT
6.1 Good Practice
78. During reporting period no examples of good practice could be presented. All
performance was implemented within planned activities.
6.2 Opportunities for Improvement
79. Condition of access road to construction site significantly deteriorated since beginning
of construction works (October 2017) due to transportation of heavy materials. Considering
duration of the project (4 years) and fact that the road is used by local population, some actions
are needed to be undertaken to improve condition of the road. It should be noted that full
rehabilitation of the road is included in the Contractor’s Scope of Works. However, in
accordance with the Scope of Works, rehabilitation has to be done after completion of the
construction.

7 SUMMARY AND RECOMMENDATIONS
7.1 Summary
80. Implementation of environmental safeguards during reporting period noticeable
improved. Particularly, per ADB and DAIIIP requests all necessary environmental permission
from relevant governmental authorities were received, Takhiatash TPP and Contractor started
implementation of environmental monitoring of construction site and in accordance with
corrective action plan. During reporting period Contractor mobilized on the construction site
International HES specialist and Sub-Contractors hired or designated international or national
environmental specialists.
81. Almost all corrective actions indicated on CAP have been implemented excluding two
actions which will be implemented after CCGT commissioning and starting decommission of
old blocks.
7.2 Recommendations
82. Requirements on conduction monitoring of ground water in term of reviewed
parameters need to be revised. A list of parameters provided in EIA (Environmental Monitoring
Table) includes analysis of heavy metals which is very costly. In addition, ground water from
wells are checked on bacteriological pollution which is very unlikely occur in monitoring wells
due to construction activities. Water from these wells are not used for drinking purposes
Therefore, it is recommended to revise a list of analysed ingredients and optimise them with
consideration of types of impacts which could be caused by construction activities.
83. In summary, the following actions are recommended for the next reporting period:
• Approve the final SEMP – 3th quarter of 2018;
• Revise monitoring activities of Contractor in term of ground water – 3rd quarter of 2018;
• Provide waste collection bins within territory of Construction camp – 3rd quarter of 2018;
• Improve practice of storage oil/fuel materials on the territory of construction camp and
sites - 3rd quarter of 2018;
• Complete rehabilitation of sludge ponds – 4rd quarter of 2018.
