I. INTRODUCTION
1.1. Project Description
1. Nurek HPP, incorporating 220 kV and 500 kV switchyards, produces over 70% of Tajikistan's
electricity.
2. The existing switchyards were built more than 30 years ago with Soviet technology and
replacement parts are no longer available. They are therefore in need of complete replacement.
The works comprise mainly: earth excavation (ca. 5,000 m³); construction of a new GIS building
covering a total area of about 700 m²; construction of 500 kV cable ducts; demolition of the old
switchyard; mainly busbars, electrical equipment and air-insulated circuit breakers; and demolition
of pylons with conductors.
3. Around the switchyards, severe soil subsidence has been occurring over many years,
requiring major continuous remedial measures. This is due to an extensive salt dome in the
vicinity of the switchyards that destabilizes the ground conditions during snow melt and rain.
There are risks for both switchyards that a catastrophic event may occur at any time, thereby
destroying major parts of the switchgear. Ground stabilization measures are considered
impractical.
4. The Government of Tajikistan (the Government) considers reconstruction of these
switchyards to be an emergency project due to the deteriorating equipment and unstable
geological site conditions with the potential for a major loss of output from the Nurek HPP for
lengthy periods. A 2006 feasibility study recommended that the equipment in both switchyards be
retired, with new switchyards built on stable ground. The study recommended that the least-cost
option was to utilize a portion of the land where the existing 220 kV switchyard is currently located
for both new switchyards. The ground conditions of the proposed new site have been verified as
satisfactory by geological investigation. Gas-insulated switchgear technology, which uses
approximately 10% of the area required by conventional air-insulated switchgear technology, is
required due to the restricted area of the proposed new site.
5. The Government signed a loan agreement with the German Development Cooperation
through KreditanstaltfürWiederaufbau (Credit Institute for Reconstruction) in August 2008 for
financing of the new 220 kV gas-insulated switchgear switchyard, with a projected completion
date of April 2011. The Project under Asian Development Bank (ADB) financing will complete the
required rehabilitation of the switchyards. The outcome will be a sustainable and reliable electricity
supply to support economic development. It will mitigate the risk of natural disasters disabling the
switchyard, and will stabilize the flow of electricity coming from the strategically important Nurek
HEPP.
6. The project for reconstruction of the 500 kV switchyard at Nurek HPP comprises construction
of a new transformer substation with SF6 insulation and dismantling of the existing 500 kV
switchyard. Figure 1 below shows the project area.

Figure 1: Project Area
7. However, for many years, soil subsidence has been occurring around the substation site
which could result at any time in a collapse, with destruction of major parts of the substation and
power supply disruption, so relocation of the 500 kV transformer substation at Nurek HPP is of
critical.
8. A contract was signed on 06.10.2009 with the consultancy company FICHTNER (Germany).
A contract for project implementation was signed with ALSTOM (Germany) (Contractor) on
15.10.2011. Subcontracts for performance of Lot 1A and Lot 1B 2 were concluded with Integral,
for implementation of Lot 1B 1 with Tajikgidroenergostroy, for Lot 2 and Lot 3 with Bozdemir, and
for Lot 5 with Zumrat.

1.2. Objective and Methodology of Bi-Annual Report
9. In May 2011, an updated Initial Environmental Examination regarding the Nurek
Rehabilitation Project was prepared. This also contains an Environmental Management Plan (in
the following called EMP) stipulating mitigation and monitoring measures for the design,
construction, commissioning and operation phases. One of the requirements within this EMP is
that the construction contractor shall set up a safety plan to the construction activities. 2012
Alstom Grid GmbH, the contractor, has prepared a report called Health, Work and Environmental
Protection Planning ‘applied to the Nurek 500 kV GIS Project for the avoidance of risks to the
health of the workforce on the job site as well as for the protection of the environment’ (in the
following called HSE Plan). The purpose of semi-annual environmental monitoring is to monitor
compliance of project activities with the EMP and the HSE Plan. This Report was prepared for the
first half of 2015.
10. Additionally, the purpose of this fourth bi-annual environmental monitoring report is to satisfy
the environmental safeguarding requirements of the Government of Tajikistan and the Asian
Development Bank (ADB) as well as to fulfill the requirements written into the loan document for
the Government (Joint Stock Holding Company “Barki Tojik”, Ministry of Energy and Water
Resources) of the Republic of Tajikistan.
11. The findings are based on a review of monthly engineering progress reports and quarterly
monitoring progress reports submitted by the Contractor (ALSTOM Grid GmbH, Germany), and
findings obtained during the supervision and monthly inspections by PMU environmental experts
for monitoring environmental impacts prepared intermittently between January and June 2015.
Further, the PMU environmental specialists regularly supervised environmental monitoring of
relevant parameters administered by the Contractor (ALSTOM Grid GmbH) as well as additionally
reviewed project design, social and associated documents. The Contractor's environmental
reports include chapters for health, environment and labor safety.
1.3. Changes in Project Organization and Environmental Management Team
12. The Executing Agency (EA) is the Joint Stock Holding Company “Barki Tojik” (BT). The EA
has set up a Project Management Unit (PMU) to manage day-to-day coordination,
implementation, monitoring and administration activities of the project. The schematic below
shows the structure of the environmental management team.

Figure 2. Institutional Chart of the Environmental Safeguards Arrangement
13. As per TOR the Consultant has one international and one national expert foreseen for the
environmental matters of this project. The international expert of the Consultant has prepared of
the Consulting Services Contract an update of the IEE in May 2011. Within OJSHC ‘Barki
Tojik/PMU’ an Environmental Monitoring Department exists that is in full operation. This
department is responsible for the implementation of the mitigation and regular monitoring
measures as outlined in the IEE Report.In addition to his duties (as outlined in the TOR), the
international environmental expert of Fichtner is supporting PMU experts with annual inspections
and additional training on all environmental issues related to this project within the frame of the
available person-months.
14. In October 2012, the Social Sector and Environmental Monitoring Department within the PMU
consisted of 8 persons. Currently it consists of 5 specialists including Head of Department. This
department is responsible for all foreign financed projects except for one World Bank Energy Loss
Reduction Project that set up its own PMU. The Social Sector and Environmental Monitoring
Department shall: work within the Barki Tojik/ PMU to ensure all statutory environmental
submissions under CEP requirements and other environmentally related legislation are fully
implemented; work within the Barki Tojik /PMU to ensure all environmental requirements and
mitigation measures resulting from the environmental assessment of the project are included in
the contract prequalification and bidding documents for suppliers and contractors; support the
development of any additionally needed IEE and IEE requirements that become apparent
following fine tuning; provide training and project awareness for Barki Tojik PMU and PIU staff
and project stakeholders; communicate with the CEP and people affected by the Project; initially
supervise and monitor Contractor’s first construction measures; investigate complaints.
15. Current PMUES staff for EM and SS is as follows:

17. For other positions, no changes to the project organization structure were made during this
reporting period. There were no changes to the CSC project organization team.
1.4. Relationships with Contractors, Owner and Lender
18. During this reporting period, the PMU of Joint Stock Holding Company “Barki Tojik” closely
collaborated with ADB, Consultant (FICHTNER (Germany)) and the Contractor (Alstom Grid
(Germany)) to review the Environmental Reports for the Program. The Contractor submitted 6
progress reports and the Consultant submitted 2 quarterly reports over 6 months.

29. As noted above, the HPP compound is well fenced, it has security guards and only authorized
persons are permitted to enter. Nevertheless, construction sites within the HPP compound are
separated by temporary lattice and wooden fencing (Figure 6 below).
Figure 6.Fencing at construction sites
30. Construction and demolition wastes are generated in the course of ongoing works, which are
managed collected, transported and disposed of in compliance with IEE requirements.
31. An agreement has been concluded and still is acting with a local company for the removal of
municipal waste and this company disposes of the wastes in the Nurek municipal waste landfill,
which is located at the distance of 3.5 km from the construction site.

32. The construction works involved disposal of spoil (inert waste). The spoil bank was located
just outside the Nurek HEPP compound in an area that was once the borrow area for excavating
materials for construction of the dam body. Currently all excavation activities are completed and
no spoils are producing.
33. Figure 7 below shows the Google image of the spoil material location near the HPP, which is
in compliance with EMP requirements.
Figure 7. Spoil and inert materials location – in compliance with EMP requirements
34. Equipment and material from dismantlement of the switchyard will be used as spares at other
hydropower stations in Tajikistan. As for the ferrous and small amounts of non-ferrous scrap –
steel, copper, and aluminum – these things will be sold to local recycling companies.
35. The sewerage system of the hydro power station is linked to the Nurek municipal sewerage
system. Sanitary facilities – toilets, bath, washing sinks – are installed and are in compliance with
EMP/HSE Plan requirements (see Figure 8 below).

36. No any oil leakages/spillage were observed at the project site.
37. As was noted in the previous report there were various types and classes of waste arising
during construction, and these were disposed temporarily on construction sites. The contractor
was advised to make arrangements for proper storage of these wastes. The situation is improved
now as all notices were addressed by Contractor.
1.5.2. Construction activities
a. Civil works for 500 kV cable tunnels
38. The figures below show the status of the works during the reporting period. No accidents

46. It should be noted that all construction works take place on the Nurek HPP property at an
appropriate distance from human settlements. Installation works do not give rise to high levels of
noise. However, the Consultant did recommend conducting routine noise level measurements at
selected construction site locations by procurement of noise meters or by contracting an analytical
laboratory, so as to record monitoring data for the first 6 months of 2015.
47. Regarding vibration, no cracks or other damage to buildings and facilities were observed
during the site visits conducted during the reporting period.
2.2. Water Quality
48. No water quality monitoring is needed as all construction is proceeding within the boundaries
of the Nurek HPP property, and the project works do not additionally contaminate the water
sources.
18
18
2.3. Air Quality
49. Earth works were conducted mainly in February-April when precipitation was sufficient. While
excavation works were conducted at dry season (May -June 2015), dust suppression was done by
watering. Access roads and construction sites were damped down where needed.
2.4. Flora and Fauna Monitoring
50. No disturbance to fauna was observed during the reporting period as, within the area of the
project site, there are no protected areas or environmentally sensitive habitats.
51. As it was described in previous bi-annual report during the constructing of GIS and cable
channels, about 25 shrubs of Euonymus gen. were removed in 2014. This vegetation type is
shown below. These shrubs have no high environmental value and can be easily replanted. The
Consultant advised the Contractor to undertake replanting after the completion of cable tunnels
works – in February-March 2015. However due to delay the measures to restore landscaping was
decided to postpone to the autumn season 2015.
2.5. Monitoring of Occupational Health and Safety, and HIV-AIDS Issues
52. No accidents were registered during the reporting period. Relevant measures were
undertaken by contractors during implementation of project works to comply with all the
requirements and measures for the protection of occupational health and safety:
· The Contractor developed and had approved a safety training program, consisting of an initial course on health and safety. All workers attended the safety training courses starting from the first week of occupancy of the construction camps. Technical safety instructions courses were held on a monthly basis.
· Workers and engineers were equipped with protective equipment and clothing, e.g. helmets, special work wear, safety belts, gloves, protective glasses etc. in good time. A first aid center has been equipped. Air conditioning and heating was provided within the building, when it is needed.
· Each three months the Contractor held an instruction course on HIV / AIDS.
· Briefings on technical safety, labor and environmental protection (including electro-magnetic fields) are held for the workforce on a daily basis.
· Arrangements have been made for proper sanitary facilities.
