INTRODUCTION________________________________________________________________
Background:
The 16 MW-Naltar III hydro power project is designed in lines with power generation development program
of Gilgit Baltistan, mainly focuses on the optimum utilization of indigenous hydroelectric power generation.
Naltar-III 16 MW project is located at Naltar Bala in Naltar valley about 50 Km from Gilgit city. The project
is to be constructed on the right bank of Nalter stream. Powerhouse will be constructed near Nalter pain village
upstream of the existing intake of 18 MW Naltar-IV Power house. The proposed project will reduce the
consumption of valuable fire wood, kerosene oil, liquid petroleum gas etc. and their destructive impacts on the
natural environment of the region. The proposed project aims to fulfill the gap between power supply and
demand in Gilgit city and surrounding villages.
This Initial Environmental Examination (IEE) presents the environmental assessment regarding the design,
construction and the operational phases of the proposed hydel power project. This IEE has been carried out to
ensure that the potential adverse environmental impacts are appropriately addressed in line with Gilgit-
Baltistan Environmental Protection Act 2014. This IEE report will be submitted to GBEPA on behalf of Gilgit-
Baltistan Water and Power Department (GB-WPD) for review and environmental approval as required by
Gilgit-Baltistan Environmental Protection Act 2014.
Environmental Regulatory Compliance:
1. Section 16(1) of the Gilgit-Baltistan Environmental Protection Act 2014 requires that “No proponent
of a project shall commence construction or operation unless he has filed with the Giglit-Baltistan
Environmental Protection Agency(GBEPA) an initial environmental examination or, where the
project is likely to cause an adverse environmental effect, an environmental impact assessment, and
has obtained from the GBEPA approval in respect thereof."
2. The National Environmental Quality Standards is (NEQS) applicable to any process emission or
effluent from the subproject. However, no such emission or effluent is envisaged from this project.
3. Pak - EPA in August 2000 issued “Policy and Procedures for Filing, Review and Approval of
Environmental Assessment”, which includes Schedules A, B and C defining development projects in
terms of requirements for EIA and IEE. Schedule A defines projects which require an EIA. It deals
with list of major projects which have the potential to affect a large number of people. The impact of
such projects may be irreversible and could lead to significant changes in land use and in the social,
physical and biological environment. The Section of Schedule A relating to Energy Sector states that
hydropower generation above 50 MW will require environmental impact assessment report. Schedule
Page 8 of 72
B defines projects which require an IEE. It deals with projects where the range of environmental issues
is comparatively narrow and issues can be understood and managed through less extensive analysis.
The Section of Schedule B states that hydropower electric generation below 50 MW will require IEE
Report. Schedule C combines everything not in Schedule A and B. Thus Naltar-III 16 MW hydel
Power Plant Project is covered by Schedule B which requires preparation of an IEE Report for
submission to GBEPA for their approval.

PROJECT DESCRIPTION AND EXISTING FACILITIES____________________________
2.1. Background & Justification
According to data provided by GBWPD, there are 25715 electricity consumers in Gilgit town, and surrounding
areas. Of these 17444 (87%) are domestic, 7743 (10%) are commercial, whereas 528 (3%) are industrial. The
total power demand is 70 MW however; the total installed capacity of hydel and thermal power plants is 30
MW. Thus there is a shortfall of 40 MW. Unless new sources of power are added, the situation is likely to
aggravate with time as the demand is projected to increase to 100 MW by 2025. The proposed 16 MW plant
will be an important project to bridging the widening demand and supply gap.
a) Project Location
16 MW run of river hydropower project will be constructed at Nalter stream. The site is located at a distance
of 50-km from Gilgit town at upstream of 18 MW intake (Figure-2.1). Powerhouse of 16 MW will be
constructed near the intake of 18MW Nalter-IV. Nalter stream connects right bank of Nagar/Hunza River
which joins River Giglit at Danyore. The project will be constructed by Power Department GB through
contractor, which will be responsible to identifying all items of work and executing them according to the
design and specifications to meet the all other requirements.

ENVIRONMNETAL BASELINE_____________________________________________________
3.1. Bacground:
The environmental and social baseline conditions have been established on the basis of information
gathered through interviews, formal and informal scoping sessions and group discussions with the communities,
departments and direct observation of selected locations in the project influnece area. Additionally, relevant data
gathered from Forest, Wildlife, Agriculture, GBEPA and Revenue department has been used for situtional
analysis of the project interventions. Secondary information form reports and relevnat publications was used for
drawing inferences.
3.2. Physical Environment
a) Physiography
Naltar valley is located on the left bank of Nagar/Hunza river in district Gilgit.. Naltar-III, 16 MW Hydro Power
Project is located at Naltar Bala. The deeply cut meandering gorges Naltar valley have lush green landscape,
thickly forest laden hill slopes, water streams lakes and milder climate, make it a famous tourist destination. The
upper parts of the valley remain glaciated throughout the year. The project area is characterized by diverse
ground topography with rugged mountains, forested valleys, alpine pastures and rich biodiversity. The mountain
slopes are generally steep to very steep in upper reaches but moderate near the mountain basis. The bed
rocks have a soils cover with varying thickness depending upon relief and aspect. Areas of steeper slopes,
with less vegetation, have comparatively thicker soils cover. In between the mountain range are the generally
narrow and somewhat open valleys here and there. Fertile valley soils in some locations support high yielding
cash crops. The valley is drained by small tributaries and ultimately joins Naltar nallah which ends up at
Nagar/Hunza River. It comprises parallel ridges having wide range of elevation. The streams are flanked
by narrow belts of land built up of the materials washed down from the catchment slopes.
b) Geology
The Naltar Valley is situated at 360 N and 740 4’ E covering a total area of 27,206 ha situated within the
Karakoram highlands. Geology is very similar to other parts of the Karakoram Range, and is dominantly
characterized by sub aerial fore-arc basaltic andesite, rhyolite, ignimbrite and volcanic clastic sedimentary rocks.
There are also Chalt group (Abtain-blain), rocks and related calac-alkaline andisites, high-Mg tholleiites and
boninites. Rakaposhi volcanic Formation and lower part of the Baumaharel Formation are also exposed (Searle
et al., 1996). The slope of the Naltar Gah is 9.3%, High mountains surround the stream having steep gradient
between Naltar Bala and Naltar Paeen section; The valley has an elevation of 2000 to 3200 m.a s.l. with
surrounding mountains towering to about 5800 m.a.s.l. in certain ranges.
Page 19 of 72
c) Seismimology
According to “Seismo-Tectonic Map of Pakistan”, a sizeable part of Gilgit-Baltistan belongs to a major
earthquake zone with recent past earthquakes upto a magnitude of M ≤ 6.5 of the Richter scale. (Referance:
Feasibility stuty for Nalter III 16 MW HPP)
d) Precipitation
The project area has an average yearly precipitation of about 572 mm. Maximum precipitation is in the form of
winter snow. Ordinarily, the hottest month of the year is July, where mid day temperatures may reach in access
of 30° C. Similarly January has the lowest temperatures and high chill factors and night temperatures reach as
low as -30° C. (Referance: Feasibility stuty for Nalter III 16 MW HPP).
e) Soils
Soils are a mixture of varying degrees of alluvial deposits, and a sizeable concentration of organic matter is
found in bowl shaped valley depressions. Such places are used for rich cash crops like off-seasonal vegetables
and potatoes.
f) Hydrology
Naltar Nallah is a perennial stream fed by rainfall, glacial and seaonal snow melt. The stream length is
approximately 42 km and the total catchment area is 270 km2 There are some small lakes above the tree line in
an area of vast grazing pastures. Total annual flow repored in the past studies is arround 9.45 m 3 / sec with
maximum flow of 29 m 3 /sec in July and August Figure-

Page 20 of 72
g) Water quality
The bacteiral water quality of Naltar Nallh is good, as anthropogenic pollution at present is bare minimum. The
use of fertilizer and pesticides is also limited. The liquid waste is being discharged in the fields. The water is
running fast and big boulders, cobbles, gravel and pebbles constitute the bed of stream. The rooted vegetation
on either bank of the stream is sparse and at a distance adding little to the biomass of the stream in the form of
falling leaves and litter. Naltar Nallah is the prime source of irrigation for habitants of Naltar Bala living near
bridige. With the exeption of witner season Naltar nallah is not used as dirnking water source by Naltar Bala and
Naltar Paeen people..
3.3. Ecological Resources
a) Forest:
Naltar valley is famous as biodiversity hot spot and decleared as game sanctuary by Forest, Wildlife & Parks
and Envrionment Department Gigit-Baltistan. Apline pastures, conferous forests and typcial annual grass are
found in lower reaches. Naltar nalah lies in lower reaches and characterized by having stepping forests.

b) Wildlife:
The topography of Naltar valley provide a good habitat for a number of wildlife species. Common wildlife
sepecies reported in the valley include World Life Department GB declared the area a game sanctuary as a mean
of protection and preservation for the endangered wildlife species. Snow leopard is already declared as
endangered species. Based on consultative sessions with the locals, forest and wildlife officials exisitng wildlife
species are summarized in Table-3.1
Table 3 1. List of reported wildlife in the project area
Source-Data derived from Wildlife Department GB and Baseline Surveys.
Birds: Besides common birds like Chakor (Alectorista graeca), Ram Chakor, there are a variety of Predators
such as Kite, Falcon, Hawk, Asiatic Vulture and Beard Vulture are common. Some migratory birds may stray to
side valley.
Reptiles: Owing to climatic severity of hot summers and cold winters, no significant reptiles have been reported
from the project area. Reptilian and amphibian fauna of the area is not well documented. However, local people
have reported some snakes, with negligible cases of any snakebite. Rock lizards are common in the region.
c) Flora in Naltar Valley:
Forests in Naltar valley falls in the category of “Protected Forests”, including the project area. Natural flora
including blue pine, spruce, birch, juniper, russian olive, wild willow, seabuckthorn, ash and wild rose are
common in Naltar valley. Common floral species of Naltar valley is given in Table-3.2

The local population has grazing, grass cutting, and fuel colletion rgihts. However, for construction purposes
local villagers need permission from Divisional Forest Officer (DFO) for cutting of pinen trees to fullfill their
construction needs. Cutting of pine and other trees for firewood and timber needs was common in the past. Their
largest wood consumption is for cooking and heating in the winters season.
Naltar valley is famous for Non Timber Forest Products (NTFPs), which are of significant economic importance
for the local population. According to a research there are 147 species of medicinal plants that are used by local
population for different disease mediantions. These include The largest ethnobotanically important family was
Asteraceae which contributed 17 species (12.06%), followed by Fabaceae (10 species, 7.09%), Polygonaceae,
and Rosaceae (8 species, 5.67% each), Lamiaceae and Salicaceae (7 species, 4.96% each), Chenopodiaceae and
Rananculaceae (5 species, 3.55% each) and Apiaceae, Poaceae and Solanaceae (4 species, 2.84% each); while
rest of the families had fewer species (Table 2). Altogether, the recorded ethnoflora comprised of 91 herbs, 27
trees and 23 shrubs. Other NTFPs include mushrooms, Black Moral and a variety of grasses, being the main
source of cattle fodder.
d) Fish Resources
Fisheries Department Gilgit-Baltitan, has established a hatchery in 1978 in Naltar Nallath. Rainbow trout,
Kamloop and Australian brown trout fish is found in Naltar stream but Fisheries Department has stopped
stocking Naltar Gah after floods. Previously increased trout fish production has decreased after the flood. There
is no commercial fishing in the project area. The fishes caught are for the personal consumption. The survey
showed that very few people consume fish as part of their diet.
Page 23 of 72
Due to fast running nature of the stream filamentous algae and other macrophytes are not found except in some
backwater where pool-like situation exists. Very few pools and puddles are located along its course no specific
site data for indigenous or native species are available. However, site-specific data of exotic species is available.
The exotic species found are brown trout and Kamloop. Discussions with local people indicate there is a low
dependence upon fishing, which is done casually mainly for domestic consumption using rods and fly lines.
3.4. Socio-Economical and Cultural Environment
a) Demography
Naltar valley comparies 22 small and big human settlemnets. The central village is known as Naltar, located in
the middle of the Naltar Valley. these human settlements are situated on either side of the Naltar stream with
additional scattered sparsely distributed clusters of habitation. The valley sides are steep but land is terraced
wherever possible for agricultural purposes. Estimated population size in Naltar valley is arround 3010 persons.
Total number of households in Naltar valley is arroud 413. .
The demographic patren of Naltar Bala village is almost similar to the other settlement in Naltar valley. The
estimated population of Naltar Bala is arround 1800 living in 200 number of dewelings. The current population
growth rate in Naltar Bala is 2.66 % with household size of 7.27 persons. People are living in joint family system.
b) Cast and Tribes
The people of the area belong to different tribes and sub-tribes such as Yashkun, Shin and Gujjars. Gujjars
migrated from Punjab some 100 years back. They mainly speak Shina. Few outsiders settled from Hunza, Nagar,
Gilgit and Nomal in the area, due to its importance in tourism and scienic beauty.
c) Education status
Based on the socio-economic survey of sampled households, the overall literacy rate (number of literate persons
per 100 populations) is concluded as 84.6%. It is about 86.3% for males and 75.5 for females which show that
the residents of the Project Area know the importance of education. Details are given in Table 3.3. Table depicts
the education level of the selected population of the Project Area which shows that the ratio of intermediates,
graduates and post graduates is low as compared to those having qualifications up to primary, middle and matric.
Based on the socio-economic survey, it was found that there are ten primary, 2 middle school and 4 high schools
in the Project Area. There is only one college in the whole Project Area. The students have to move to Gilgit for
degree or higher education. Village-wise education facilities found in the Project Area are shown in Table 3.4.

d) Health Status in Project Area
Health care is provided by five BHUs in project area two in Naltar and three in Nomal. There is no qualified
doctor, only dispensers give medicine to the patient’s. In emergency, patients especially in maternity cases, are
taken to Gilgit hospital. Some old experienced women in this field make deliveries at home.The interviews with
local population in the project showed that seasonal diarrhea, gastrointestinal fever and cold and
tuberculosis/asthma are common. The children and women are particularly more vulnerable. Women health care
Center and better health facilities should be provided, especially LHV: may be trained and appointed in the
villages.
e) Agricultrue and crops
Residents of project area rigidly follow traditional cropping practices. Maize and wheat are the main crops.
Potatoes are being cultivated as cash crop in higher altitudes. Oilseeds, pulses and others crops are negligible.
Due to the relatively steep slopes terraced fields are very small and cropping intensity is high.
Maize and Potato is cultivated on 100% and 80% of available agricultural land in project area respectively.
Onion and Peas are also partially cultivated in project area. Average production of wheat, maize and Potato is
Page 25 of 72
103, 173 and 1,000 Kg/kanal, respectively. Fruit trees were also reported in project area. Walnut, apricot, apple
and almond are found in abundance. Cherries of Nomal are famous for their taste and quality.
f) Livestock and animal hausbandary
Livestock and animal hausbandery is also one of the the main income source of comunity living in the project
area. Poultry, in the form of hen keeping, is common practice by most families. Meat, milk, butter and eggs are
the main livestock products. In Nalter valley goats, sheep, cows, bulls, donkeys, mules, and yaks are comon
livestock species.
g) Icome source
Agriculture and animal hausbandry are the main sources of income generation in the project area. However most
of the households need additional money to satisfy their various daily needs. So, majority of the male population,
even children, go to other parts of GB and down country for employment and jobs. Seasonal migration in winter
time is the general strategy to substitute food production by cash availability. Only their dehqans stay behind in
Naltar to take care of their homes and other property.
h) Water Sources and uses
Springs, galcieal, lakes and snow melt are the principal sources of water in Naltar Valley. Water from these
perennial source comes to Naltar stream and is used for irrigation, drinking and other domestic uses through out
the year. Sine pipe water supply in the entire valley is unsatifiacory therefore populaiton fulfill drinking water
needs from nearyby springs or Nalter stream.
i) Tourism in the project area
Naltar valley is famous due to a number of touristic attractions such as lakes, forests and wildlife rehabiliation
center constructed by Wildlife and Parks Department of Gilgit-Baltistan. However, trousit faciliteis are lacking
in the area. Naltar Bala is famous due to winter skeing tournamnet jointly orgnaized by Governemnt of Gilgit-
Baltisan and Pakistan Air Force.
There are three lakes in Naltar Valley known as Naltar lakes or Bashkiri Lakes at an altitude ranging from 3050–
3150 m. The first Bashkiri Lake is located at a distance of 12 kilometers from Naltar Bala The road up to the
Page 26 of 72
lakes is a non-metallic dirt-road alongside a rivulet, flowing down the valley. The lakes are surrounded by dense
pine forests, during winters it becomes almost impossible to reach the lake with any vehicle due to the heavy
snow (10 to 15 feet high) on the road

ENVIRONMENTAL AND SOCIAL IMPACT ASSESSMENT AND MITIGATION
MEASURES_______________________________________________________________________
4.1. Background:
This chapter of the report highlight the potential environmental impacts of Naltar-III 16 MW project and propose
mitigation measures to minimize the impacts in the design, construction and operational phases. The process of
impact prediction is the core of the environmental assessment process and it is critical that the recommendations
and mitigation measures are carried out during the construction and operation of the project in accordance with
the Gilgit-Baltistan Environmental Protection Act 2014, and its sub-sequent rules regulations and draft
guidelines to address environmental issues related to hydro power projects in the context of Gilgit-Baltistan.
The environmental assessment of the project is conducted, principally, within the framework of Gilgit-Baltistan
Environmental Protection Act 2014, IEE/EIA regulations 2000 and Guidelines for the preparation and review of
environmental reports. To identify the impact of the project on the physical, biological and human environment
of the project area and to categorise them in accordance with their significance, a Project Impact Matrices has
been prepared. All the project activities are divided into three phases;
Design phase
Construction phase; and
Operational phases
4.2. Design Phase Impacts
The design phase mainly comprises of feasibility study and detailed design for the proposed project. The
consulting firm responsible to carry out feasibility study was given the following ToRs for Naltar-III 16 MW
project in Naltar Valley.
Collection and review of feasibility report prepared by Hydro Electric Planning Organisation (HEPO)
WAPDA in collaboration with German Agency for Technical Cooperation (GTZ).
Collection and review of Comprehensive Planning of Hydel Resources of Tributaries of Indus River in
Northern Areas of Pakistan prepared by Hydro Electric Planning Organisation (HEPO) Wapda in
collaboration with German Agency for technical Cooperation (GTZ) (Gilgit Region).
Collection and analyses of additional basic data
Review of the power market
Technical redesign of the systems and performance of layout studies
Up-dating of unit cost and Bills of Quantities
Economic and financial analyses
Field surveys with respect to involuntary resettlement and environmental aspects
Page 28 of 72
Establishment of environmental and resettlement impact mitigation concepts for the project.
Since there will be no any major activities during design phase except site inspection, topographic surveys,
geological mapping and sub-surface investigation at the proposed site. Most of the activities do not require
extensive physical interference in the project area, therefore, no significant environmental, socioeconomic and
health impacts have been identified.
4.3 Construction Phase Impacts:
Construction related activities would result short term negative impacts in terms of noise, dust and exhaust
pollution on the nearby settlements and specifically to the sensitive receptors like school, madrasa residential
area and hotels.
The construction phase impacts are mostly of a temporary nature and their magnitudes are subject to the
engineering management practices adopted during construction phase. During construction most of the impacts
will be of negative nature, but most of them are temporary and will vanish with the completion of project. Major
environmental impacts during construction phase and proposed mitigation measures are discussed in following
sections. Summary of environmental impacts in construction phase is given in Table-4.1

I) Topography
The interventions of the Naltar III 16 MW HPP are not likely to impact the topography of the area on a large
scale except for those areas where the physical activities of excavation, digging and movement of heavy
machinery will take place. Similarly, areas where excavated material will be disposed, dumped or stored will be
negatively affected. This impact can be considered as a negative impact with moderate magnitude.
Impact Impact Level Mitigation
Minor topographical impacts due
to dumping, cutting, excavation
consturction of access roads,
destabliztion of slopes at power
house site.
Minor magnitude Leveling of soil dumps in agricultral fied.
Bioengineering measures will be taken to stablize
slopes with similar vegetation types.
II) Geology
Impact Impact Level Mitigation
Distrubance of exisiting stable
geological formation due to
blasting, extensive excavation,
cutting of formations that may
result more landslides events.
Minor magnitude Blasting will be avoided where possible.
Grater number of low power blast should be
prefered instead of high intensity single blast.
Stablization measures will be taken after cutting
of slopes.
III) Landuse
In addition to the permanent land requirements, temporary land acquisition will be needed at three sites, i.e.
diversion weir, penstock, powerhouse and quarry sites. Total area for temporary acquisition is estimated at 0.2
Page 30 of 72
ha which will be mostly the riverbed or pasture lands, and 0.12 ha is the farmlands. This land will be acquired
for a maximum period of three years.

Agriculture department.
IV) Excavated Material
During construction of the project a very large quantity of excavated material is expected to be generated from
the project activities. Unplanned disposal may create environmental degradation of the area and environmental
issues of significant adverse impacts can emerge during construction of the project. The nuisance created by
excavated material will be a major negative impact of the project.
Impact Impact Level Mitigation
Destruction of Environment and
asthetic values of the area.
Major negative
impact Excuated material will be dumped in an
environment friendly maner to minimize negative
impact on surrounding environment.
Volume of excavated material should be reduced
by avoiding uncessary excavation. The top soil
will be used as cover material in nearby
agriculaual fields and land developement in
selected areas.
V) Impacts on existing infrastructures
Since most of the project components are located in out of inhabited area therefore no adverse affect of project
installations will occure. However, due to construction of new forebay area, chennal and road 5 households
will be demaged.
Impact Impact Level Mitigation
5 number of housholds will be
damaged during construction of
channel and forebay.
Moderate to high
negative impact Measures will be taken to minimize damage of
infrasturcture during alignment of physical
components of the project.
Owners of the demage property will be
compensated as per existing markeet rates.
Page 31 of 72
VI) Impacts on Climate
No impact on climate of the whole project area is expected due to construction of Nalter II 16 MW HPP, either
positive or negative, during the construction phase. Project construction involves large scale activities including
the movement of different types of light and heavy traffic, working of heavy machinery, blasting of rocks,
operation of batching and mixing plants and the presence of large numbers of workers in the area. Due to these
activities, it is expected that the microclimate of the project area will deteriorate significantly.
Mitigation
The deterioration in the local climate during the construction phase will be of a temporary nature and will
disappear with the completion of the project. However, special measures will be adopted to reduce these impacts
during construction phase.
VII) Surface Water
Impact Impact Level Mitigation
Physical and biological water
quality will be affected by project
activities such as wier construction
activites, wastewater dispoasl from
camping, oil and chemical spiolage
from machinery.
High to moderate Proper disposal of liquid and solid waste will be
ensured during construction through constrution
of septic tanks and dumping of solid waste as per
agreed gudieliens with GBEPA.
Vehicle parking and service areas will be
established away from water sources with proper
draniage facilities.
VIII) Air Quality
The project activities will involve large movements of heavy diesel operated machinery and vehicles which
produce more noise and generally emit more smoke. Similarly, various levels of noise and air pollution are
expected to be generated from construction machinery and equipment, working of heavy earth moving
machinery, drilling, blasting operations, concrete mixing, pouring equipment and stone crushers etc. All these
activities will become major sources of noise, smoke and dust pollution. High noise and air pollution level if
not mitigated will cause major adverse health impacts on workers on the project site and on local communities
living in surrounding areas. The pollution in the air in the form of dust, vehicle exhaust, particulate matter,
aerosols, smoke and gases will increase besides an increase in noise pollution. The impact on air quality is
considered as short duration negative impact of moderate magnitude

Spoil material will be used for land
developement along Naltar Nallah in
consultation with local people and GBEPA.
IV) Impacts on Hydrology
The hydrology of the proposed Nalter 16 MW HPP starting from upper limit of weir intake to the end of the
tailrace channel is expected to change significantly during operation of the project. The water flow pattern will
change as significant volume of water will be diverted towards headrace tunnels to generate power. The flow in
this part of the river will reduce drastically below historic flows. However, as there is minimum human
population on this section of the river getting any sort of benefit, no negative impacts on human population are
anticipated due to changes in the hydrology.

V) Impacts on Air Quality
During operation of the project, the air quality of the area will improve significantly as compared to the air
quality of construction phase.
VI) Impacts on Agriculture
Agriculture in the project area is practiced on scattered flat patches and on contour strips developed by the
farmers with their own efforts and resources. The main source of irrigation in the area is the snow melt water
diverted from streams towards crops and orchards and no irrigation is practiced from river water in any part of
project area, and no major impact on agriculture is expected in the project area with the implementation of the
project.
V). Impacts on Flora and Fauna
No major impact on Flora and Fauna of the area during operation of the project.
VII) Aquatic Life and Fish Stocks
Page 38 of 72
Fishing in project area is not common as the river bed is steep, water velocity is high and the river flows in a
deep gorge which is not easily assessable. No specific site data for indigenous or native species are available.
Department of Fisheries has established a hatchery in Nalter valley just above the weir intake of 16MW HHP.
Discussions with community shows that there is low dependent upon fishing. However, Naltar Nallah is a
potential breading gournd for tourt snd other native fish sepecies. Mid to high level of environmental impact
may happen if following mitigation measures would not be taken into account.

VIII) Impacts on Power
The most important and significant impact of the project will be the power generation as Gilgit-Baltistan is
presently facing acute shortage of power. The power generating capacity of the project is estimated as 16 MW.
The power generated will help to establish new industries, to boost commercial activities and to enhance job
opportunities in the area. Electricity generation impacts are considered to be most significant positive impact of
the project.
IX) Impacts on Employment Opportunities
During operation, as compared to the construction stage, a small number of people will benefit from employment
opportunities. However, even during this stage, a large number of both skilled and semiskilled manpower will
be required, who will be recruited from the local area. Employment generation during the operation phase is
considered to be of a moderate positive nature.
X) Impact on Women
Contrary to the construction phase, there will be much less movement of vehicles as well as people in the area
during the operation phase. In addition, women of the project area will be able to avail the facilities created
during construction stage of the project. Thus during this phase no negative impacts on women are expected.
Summary of impacts during operational phase is given in Table 4.2.
Page 39 of 72
XI). Impacts on livestock
The proposed intake and chanel is lacated at the bank of Naltar Gah which is not used as grazing area for
livestokc. However, in the forebay there is minor chances that animale may fall in the forebay. Inorder to minize
such incidents fencing will be ensured arround forebay and open channels. Similarly, environmental flows
recomended in this report should be maintaiend in low flow seasons to cater the domestic and livestok needs by
W&P Department.
4.5. Positive Impacts
1) The proposed 16 MW plant will be an important project for bridging the widening gap between demand
and supply in Gilgit town. At present, there are 25715 electricity consumers in Gilgit town and
surrounding areas. Of these 17444 are domestic, 7743 are commercial, whereas 528 are industrial. The
total power demand is 70 MW. At present total installed capacity of power projects for Gilgit town is
55 MW. However, according to W&PD the current generation is about 23 MW, thus there is a shortfall
of about 46 MW. Unless new sources of power are added, the situation is likely to aggravate with time
as the demand is projected to increase to 20 to 30 MW by 2020.
2. Existing drinking water supply systems in Naltar Bala needs rehabilitation. The whole of the population
depends on springs and Naltar Nallah for drinking water during lean periods. It has, therefore, been
suggested to rehabilitate the existing drinking water supply scheme at Naltar Bala on the demand of
villagers. The provision of water supply scheme planned under the project will be a significant
development. This is suggested that contractor will rehabilitate water supply scheme in this village.
3. Availability of power would reduce consumption of fuel wood by villagers for heating and cooking
purposes.
4. The project will provide unskilled jobs opportunities during the construction phase and a limited number
of 20 jobs during project operation to locals.
5. Hydropower is a clean and renewable source of energy and its use instead of thermal power reduces the
emission of pollutants such as carbon dioxide (CO2), particulate matter (PM), Sulphur dioxide (SO2),
carbon monoxide (CO) and oxides of nitrogen (NOx), and hydrocarbons. One way of mitigating the
impacts of Green House Gas Emissions is replacing and/or developin clean energy sources (hydropower
and solar) as alternate to the dirty energy sources (thermal, oil, coal etc.). To realize this UNFCCC has
introduced various mechanisms including CDM. Development of 16MW Naltar HPP will contribute to
the climate change by mitigating/replacing the diesel gen sets prevailing in the area to offset the shortage
of energy. The estimated values of emission reductions from the project (with 80% Plant Factor and 21
years project life) and Carbon revenues have been summarized in the following:
Plant factor consider = 68%
Project life determined= 21 years
Emission Factor = 0.8 (default)
Page 40 of 72
Carbon emission reduction= 1280950.272 tCO2 eq
Considering $ 5/CER rate during the project life emissions in the Carbon Market
Carbon revenues $ = 7535000 (over 21 years @ $5/CER)

STAKEHOLDERS ONSULTATION_________________________________________________
In order to take on board relevant stakeholders on the project and to record relevant issues a series of meetings
were held during preparation of this report. The objectives of the stakeholder’s consultation were as under;
To overall objective and important component of the project.
To collect information on expected long and short-term impacts.
To collect information on the key issues by stakeholders especially communities
To recommend appropriate mitigation measures means to resolve the issues during implementation and
operationalization of the project.
Stakeholders of the Project:
Key stakeholders of the project are communities of Naltar Bala, Naltar Paeen, Department of Forest, Department
of Wildlife, Department of Fisheries and Armed Forces of Pakistan. Other stakeholders are non-governmental
organizations, and government departments particularly the GB-PWD.
Consultation Process
Consultations were carried out through focus group discussions, public meetings, community discussions with
key stakeholders, and formal meetings with government officials, to ascertain their views and identify their needs
and preferences for compensation and rehabilitation measures. During the consultation, the stakeholders were
informed about the project and their concerns were recorded. Views on compensation and related issues were
also discussed with the persons likely to be affected by land acquisition. Photographs of the scoping sessions /
consultations are placed at the end of the report.
Summary of Consultations:
Following are the findings of stakeholder’s consultations;
i) In general, everyone welcomed the project. No one expressed any concerns by the project itself.
ii) Community demanded fair and speedy compensation of the affected assets.
iii) Compensation should be at market rate in consultation with community.
iv) Employment opportunity for local people during construction and operation phase was key issue of
Naltar Bala and Naltar Peen communities. Community demanded fair allocation of jobs and
recruitment.
Page 42 of 72
v) Community showed serious concerns regarding water flows in Naltar Nallah especially in winter
when whole Naltar water will be diverted towards weir of the project. They demanded alternate
drinking water arrangements by project management.
vi) Since landholdings are very small, to the extent possible project should avoid land acquisition.
Meetings with officers of line departments
The team of consultants’ also visited line departments in Gilgit to obtain information on various aspects of
Fisheries, Wildlife, Agriculture, Health and Land acquisition and Forest. The list of Line Departments visited is
given in Appendix II.
Future Consultation
Extensive public consultations were earlier conducted in the project area during preparation of feasibility report
of the project. Similar consultation with communities of Naltar Bala and Paeen were held in February 2018.
Such an exercise will be continued during implementation phase of the project, especially during alignment of
headrace channels with local communities, armed forces, forest department and other relevant line agencies to
take them on board. The objective of the future consultation will mainly focus on define actual losses and land
acquisition, timing of work, overall schedule, minimizing disturbance to business, and public safety and gender
issues.
Procedure for Public Disclosure
In promoting transparency and accountability, PMU will continue to provide relevant information to the
stakeholders in a timely manner in a form and language (urdu) that are understandable and accessible to them.
Illiterate people will be informed verbally during regular consultation process by the PMU. Following procedure
will be adopted for information dissemination to public;
PMU will disclose the IEE report and related documents to Gilgit-Baltistan Environmental Protection
Agency. IEE report will be disclosed at the water and power departments website. The local community
will be provided with the Summary of IEE report and project information at different stages of the
consultation in Urdu either in written form or verbally.
The information will be made available in locations that are easily accessible to stakeholders. Depending
upon the capacity of a stakeholder and nature of the information to be disseminated, such locations can
be local villages, project site office, PMU office, government department or local government setup
Overall, the consultation activities and disclosure will be designed so as to maximize community
awareness of the project and to create reasonable opportunities for community input and involvement.

Chapter-6.
INSTITUTIONAL REQUIREMENTS & ENVIRONMENTAL MANAGEMENT PLAN_____
6.1. Institutional Arrangement
Gilgit-Baltistan Water and Power department will be the executing authority. GB-PWD will exercise its
functions through establishing a Project Management Unit (PMU), at project site headed by a full time Project
Director who will be responsible for general project execution. In this regard, a well-defined institutional
structure will be placed in the PMU and staff will be assigned to specific roles. The PMU will ensure compliance
with the Gilgit-Baltistan Environmental Protection Act 2014 and its rules and regulations.
Under PMU, an Environment and Social Development Cell (ESDC) will be established which will be
accountable and responsible for implementation of EMP. The ESDC will initially consist of one environment
specialist, who will be directly hired by GB-WPD to provide technical assistance in implementation of the
environment and resettlement plans. The number of staff/members may be increased depending on the number
and nature of project activities. The ESDC will work in close collaboration with the respective PMU to
implement EMP. The ESDC will also be responsible for internal monitoring. The project Coordination Office
will ensure budgets are delivered in time to the competent authority for timely implementation of EMP. The
EPC contractor of the project will have a full-time health, safety and environment (HSE) officer to manage the
tasks assigned under this IEE.
6.2. Complaints & Grievances Redress
For the purpose of addressing grievances by the community about the implementation of IEE and EMP, a
Grievance Redress Committee (GRC) will be established for the project as soon as project implementation
commences. However, with careful observance of the provisions of the EMP by all stakeholders involved,
grievances can be avoided.
The Committee will be established at the project level with the primary objective of providing a mechanism to
mediate conflict. The committee will constitute the Project Director, one elected representative, one
representative of district revenue officer and three representatives of the affected community.
If necessary, the aggrieved person will first address the complaint to Grievance Redress Committee who will
strive for settlement within 10 days of lodging of the complaint. If the complaint cannot be settled, the grievance
will be referred to ESDC. Within 30 days the Grievance Redress Committee will discuss the matter and refer
the grievance to PMU, and obtain a resolution. If the grievance redress mechanism fails to satisfy the aggrieved
person, s/he can approach the Gilgit Baltistan Environmental Protection Agency or court of law.
Page 44 of 72
6.3. Environmental Management Plan
This IEE concludes that the construction impacts will be manageable if the mitigation measures are implemented
carefully. An Environmental Management Plan (EMP) has been prepared (Table 6.2) by close reference to the
best practices and in line with GBEPA 2014 and IEE/EIA Regulations 2000. EMP is based on the type, extent
and duration of the identified environmental impacts, mitigation measures, their timing, location, and
implementation/ monitoring responsibility. PMU should check that contractors have all the necessary valid
licenses and permits such as those for use of powered mechanical equipment.
6.4. Monitoring & Evaluation
The environmental performance of the project will be monitored internally by the PMU and ESDC. The
information will be collected directly in the field by ESDC on monthly basis to assess the environmental
performance of the project and to adjust the work program, if necessary. The monthly and quarterly reports will
be communicated to GB-EPA on standard formats.
An environmental monitoring plan showing implementation responsibilities and schedule has been drawn up
and places as Table 6.1 Monitoring activities during implementation will focus on compliance with license
conditions, recording implementation of mitigation measures, recording environmental parameters, reviewing
contractor environmental performance and proposing remedial actions to address unexpected impacts during
construction.

Findings & Recommendations____________________________________________________ This IEE report has been prepared based on the secondary data of feasibility report, primary data collection
through relevant department, and extensive consultations with communities and proponent. In-situ
environmental surveys were carried out in order to complete the environmental assessment and
recommendation of suitable mitigation measures. Following are the key findings and recommendations;
The negative environmental impacts from the project will mostly take place during the construction
stage but there are also some potential negative impacts for the operational stage as well as many
significant beneficial impacts. The construction impacts are very predictable and manageable and
with appropriate mitigation few, residual impacts are likely.
Communities of Naltar Bala and Naltar Paeen are not fully aware about the project interventions.
They have serious concerns on compensation and job opportunities in the project. PMU should
conduct follow-up visits to take onboard the communities on project interventions and to arrange
satisfactory compensation for short term land acquisition as per current market rates.
In order to minimize the negative environmental impact during construction phase, PMU should
include the IEE and EMP, updated if necessary, as contractual requirements, accepted by all
contractors prior to 'signing the contract(s). The contractor will be required to prepare an SSEMP
including temporary traffic management, materials management master plan, waste management
plan, blasting management plan and oil spill management plan. The SSEMP should be deliverable
by the contractors and approved by GBEPA before construction commences.
PMU should conduct a review the monitoring activities proposed in this IEE to establish the
parameters to be checked during the construction and operation in consultation with GBPEA.
The IEE, including the EMP, should be used as a basis for an environmental compliance program
and be included in the contract documentation. The EMP shall be reviewed at the detailed design
stage. In addition, any conditions that are part of the environmental clearance from the GBEPA
should also be as a basis for the environmental compliance program.
Continued monitoring of the implementation of mitigation measures, the implementation of the
environmental conditions for work and environmental clearance, and monitoring of the
environmental impact related to the operation of the project should be properly carried out and
reported monthly to track and determine the net environmental benefits that have accrued.
Implementation of the environmental mitigation measures during the construction phase should be
responsibility of contractor that should be included in the contract and implementation should be
monitored by PMU.

CONCLUSIONS_______________________________________________________________
i) Environmental impacts during construction and operational phases of the project, as identified
in Chapter-4, should be mitigated. In order to implement mitigation measures institutional
arrangements are to be made available. For effective implementation of the mitigation plan,
payment milestones should be linked with the implementation of the recommendations based
on mitigation and management plans.
ii) Monitoring activities will need to focus on compliance with license conditions, recording
implementation of mitigation measures, adherence to agreed waste disposal practices,
reviewing contractor environmental performance and proposing remedial actions to address
unexpected impacts.
iii) The implementation of the Naltar III is a feasible and sustainable environmental option but
thorough implementation of the EMP is required throughout the design, construction and
operation of the project in order to minimize impacts and retain public support for the project.

ENVIRONMENTAL FLOW ASSESSMENT_______________________________________
INTRODUCTION
Naltar-III Hydropower project aims to generate 16MW of electricity under a design flow of 5.2 m3/s using
3 Pelton Wheel Turbines. The minimum flow requirement to keep the plant in operation is 2.7 m3/s to
generate 5.3 MW electricity in winter season.
Based on the mean annual flows in Naltar Nallah, the source water will be diverted towards power house
in minimum flow periods. However, keeping in view the downstream water flow requirements to maintain
aquatic life and domestic use of water, it is important to allow a certain share of water, generally referred
to as environmental flows, through the existing course of the water so that biological life in the affected
stretch can be maintained. While in principle the concept of environmental flows is accepted uniformly, the
methodologies for establishing the levels of environmental flows vary considerably amongst experts,
environmental agencies or countries. In Pakistan, there does not exist any specific legislation or ruling or
instruction from relevant governments or statutory bodies or regulatory agencies which establish a specific
framework or methodology for determining environmental flow. Consequently, in water resource
development schemes, where the level of environmental flows has to be established, consultants rely on
existing precedents or use their own experience and understanding to propose such flow requirements. In
this note, the environmental flow adopted for Naltar-III Hydropower Project is discussed for further clarity
and understanding.
ENVIRONMENTAL FLOW ASSESSMENT METHODOLOGIES
There are many formulas for the calculation of environmental flow. At present the number of formulas
worldwide is 207 [1]. This number is tending to increase day by day. This demonstrates that no good
universally valid solution for environmental flow determination exists at the moment and probably will
never exist. The various groups of formulas available for Environmental Flow Assessment (EFA) are based
on the following aspects [2].
i) Methods based on hydrologic or statistic values;
ii) Methods based on physiographic principles;
iii) Formulas based on velocity and depth of water; and
iv) Methods based on multi-objective planning taking into consideration

ecological parameters.
For calculations of environmental flows in Nalatar III project, a comparative analysis was done by using
CEMAGREF formula and EF Montana Method. These two methods have been applied in various hydro
projects in Gilgit-Baltistan and other parts of Pakistan. Analysis of environmental flows has been given in
the following sections.
CEMAGREF FORMULA
According to this formula Q = [(0.0651 Qmm+2) /100] Qam (Ref. CEMAGREF: Agricultural and
Environmental Research Institute, Antony, France; Formula developed for Minimum Flow for Ecological
Requirements, 2006) where Qmm is mean minimum monthly flow and Qam is annual mean discharge of
the Naltar Nullah at the weir site. Using 2.09 m3/s for Qmm and 9.47 m3/s for Qam, the required ecological
flow Q is equal to 0.21 m3/s as environmental flow.
The same formula was earlier used by Fitchner Consultants of Germany for 106 MW Golen Gol HPP,
Chitral Pakistan. Golen Gol HPP is being developed by WAPDA, the state-owned organization for the
development of water resources and hydropower.
The EIA for Golen Gol HPP has already been approved by EPA showing no reservations on the
environmental flow calculation method.
This formula was later on used by Star Hydropower Ltd. for ADB finance 147MW Patrind Hydropower
Project, AJ&K, Bunji Hydro Power Project EIA and Thak hydropower IEE. The following Table-1
compares the Formula value of 0.21 m3/sec as environmental flow with the estimated monthly flows of
Thak Nullah in the reach from weir site to powerhouse site.
Page 62 of 72
Environmental Flow Requirements (m3/s) based on CEMAGREF FORMULA
The Table shows that the quantity of water available for power generation from October to May every year
would be less than the design flow of 5.2 m 3/ /s e less than the design flow of 1.7m3/s. The required
environmental flow during these lean months is in order of 4 to 10% of the total flow. The effect on aquatic
life during these lean months October to May is not considered significant when viewed from the fact that
substantial fish culture does not exist in the reach under consideration. Therefore, diversion of the stream
for power generation in the section immediately downstream of the weir will not affect fish population
indicating insignificant impact on the fishing.
EF Montana Method
The period November to May is a period of lean flow as given in the Table -2. According to this method
10% of lean months average flow which is 0.163 m3/sec has been considered as environmental flow for
bare survival of biota in vulnerable reach during this period. Flow of water available for power generation
at full capacity is more than the designed flow of 5.2 m3/s in the months from April to November. The
minimum flow requirement to keep the power plant in operation is 1..73 m3/s when only one turbine will
be generating 5.3 MW power during the lean months from November to April March after release of

The table shows that during the lean months period the release of environmental flow downstream of weir
site will not in any way compromise on water availability for power generation thus having least impact on
power generation while ensuring the downstream ecological requirements from 17 to 48% as compared to
10%.
CONCLUSION
• Two methods, namely, CEMAGREF Formula and Montana Method have been used to assess the
environmental releases downstream of the weir.
• According to CEMAGREF Formula environmental flow varies from 4 to 10% of natural flows
during lean months from November to April every year.
• According to Montana method the environmental releases during lean months are above 10% of
natural flow, varying between 17 to 48%.
• The average of environmental flow during lean months (0.83 m3/s) is 30% of average annual flow
(9.47m3/s) which, therefore, has been adopted for the project.

SOLID WASTE MANAGEMENT PLAN__________________________________________
Construction Phase
Construction processes and accommodation of workers will produce much solid waste. Solid waste
components are paper, timber, plastic, iron, non-iron metals, and glass etc. At the construction site and all
labour camps, a trash disposal system shall be implemented in order to collect all materials.
For proper disposal, segregation, recycling or treatment facilities will have to be established at one place.
Waste material such as metals, plastic, timber, and paper would be treated accordingly for transport towards
down locations in Pakistan. Some of the solid material, in order to avoid additional transport, could be used
for meeting local energy needs. However, strict legal requirements on emission standards will have to be
kept in view.
1. Non-Hazardous Waste
Non-Hazardous Waste includes mainly the construction waste generated during land clearance, excavation
work for headrace channel, forebay and powerhouse, concreate and asphalt, wood, bricks, glass, plastic and
papers and other ferrous/iron products.
Mitigation measure
Recycle or reclaim material where possible
If recycling is not practice, waste must be disposed through an appropriate of-site disposal facility in an
environmentally acceptable manner and in with environmental laws.
The construction material will be kept in a covered area, especially during the rainy season
The excavated material will be re-used by adopting different methods, which will be used as a filling
material.
Separately labeled waste containers/bins for different types of waste will be deployed in order to
collect/treat waste. The waste bins will be properly marked for each type of waste produced during the
construction activities.
Solid Waste would be disposed within designated area as per environment friendly protocols
2. Hazardous Waste
Hazardous waste includes corrosiveness, toxic substances, paints, acids, diesel and other oil. The handling,
storage and transportation of hazardous substance should be managed properly to minimize the risks.
Mitigation measures
All hazardous material should be stored in clearly labeled containers and vessels.
Storage facility will be regularly monitored and inspected
Curbs or drip pans should be provided under potential leak sources
Prohibit use of lead based paints
Page 67 of 72
Prohibit asbestos containing material
Operational Phase
Improper collection and disposal of waste during this phase results in the contamination of ground water
and aesthetic/visual values of the area.
All reusable and recyclable (non-biodegradable) waste/scrap will be given to scrap dealers.
All biodegradable waste (food and kitchen waste) will be collected and disposed into designated pits or
transport to municipal waste collection and disposal facility at Chilmishdas near Faizabad Village Nomal.

Annex-V
PERSONAL PROTECTIVE EQUIPMENT INVENTORY AS PER NATURE OF WORK
Required personnel protection equipment (PPE) must be worn at all times when on construction site. At a
minimum, each employee is required to wear a hard hat and safety glasses. High visibility safety vests with
reflective striping are required when employees are exposed to vehicular traffic. In the absences of vehicular
traffic, high visibility shirts should be worn at all times. All workers must wear shirts with sleeves, long
work pants, and sturdy work shoes or boots when working on a construction or renovation site. Sleeveless
or tank top shirts, short pants, sweatpants, sneakers, sandals, and high-heeled or open-toed shoes are not
permitted.
Depending on the circumstances and potential hazards present, additional PPE may also be required.
Additional PPE may include:
Protective gloves
Hearing protection
Full face shields when cutting, grinding or chipping
Chemical splash googles
Respiratory protection where required
Full protection equipment when working above 6 feet
Specific protective clothing such as welding leathers when welding or fire resistance clothing when
working with live or high electricity devices /equipment’s.
The Health and Safety Officer/supervisor will maintain a register as per following schedule;

TRAFFIC MANAGEMENT PLAN_______________________________________________
The project area is approachable only along Nomal-Nalter road, which is not sufficiently wide for
movement of heavy machinery and is very risky. There are many dangerous sharp turns on Nomal-Nalter
Road. It is difficult and very risky for heavy machinery and vehicles to move for transportation of required
equipments and material. The road has a dangerous narrow carriageway and bridges insufficient to carry
the expected traffic load. Project related traffic does not cause impacts to local population or environment
if, the drivers and other related personals operate/drive vehicle in a safe manner. However to avoid any
nuisance from traffic following measure should be taken during construction of 16 MW Hydropower
project;
Sinages will be displayed for general public and project workers at different locations on the road.
Sinages should be in urdu and english languages for guidance of toursits.
Measures for the safe disposal of construction and excuated matrial.
The weather conditions must be known before the start of the journey from Met office and drivers must
be briefed before the start of the journey so that cargo may be protected from rain damage and driver
may plan the journey accordingly
Upgrade all Project related roads to appropriate standards for safety
Educate all nearby villages on road safety
All vehicles must be maintained to manufacturer’s standards including regular maintenance of tires,
breaks and lights.
Capacity building of drivers on defensive driving
Avoide vahicle movement durimg night witout headlights
Ensure PPE to drivers and other vahicle related personels
