EXECUTIVE SUMMARY
Green Earth Environmental Consultants have been appointed by Namib Poultry (Pty)
Ltd (NPI) to attend to and complete an Environmental Impact Assessment (EIA) and
Environmental Management Plan (EMP) in order to obtain an Environmental Clearance
Certificate for the proposed construction of a 4 Megawatt Photovoltaic Plant (PV Plant)
and Overhead Power Lines on a Portion of Portion 7 of Farm Klein Okapuka No. 51,
Khomas Region as per the requirements of the Environmental Management Act (No. 7 of
2007) and the Environmental Impact Assessment Regulations (GN 30 in GG 4878 of 6
February 2012).
The land within the immediate vicinity of the proposed solar plant is predominately
characterized by natural open spaces associated with farming, abattoir and bakery
activities. In terms of the Regulations of the Environmental Management Act (No 7 of
2007) an Environmental Impact Assessment has to be done to address the following
‘Listed Activities’:
ENERGY GENERATION, TRANSMISSION AND STORAGE ACTIVITIES
1. The construction of facilities for -
(a) the generation of electricity;
(b) the transmission and supply of electricity;
The key characteristics/environmental impacts of the proposed project are as follows:
Activity Impact
±16ha area must be cleared to accommodate the Photovoltaic Plant and transfer station
Low impact – area already cleared in the past, mainly covered by intruder bush and impacted by human activities and grazing interference
4-Megawatt PV Plant to be constructed in 2 phases of 2 MW each
Low impact – phasing improves the feasibility of the project
PV modules to be fitted on aluminium/steel single axis solar tracker for optimized energy gain 1.2m above ground for reduced heat reflection
Positive impact – improved efficiency of operation of the PV Plant
PV Plant area to be fenced off with a security fence to prevent human and animal interference
Low impact as fence does not interfere with animal, human or vehicular tracks
3km of overhead lines to be constructed to link PV Plant with existing NPI Substation
Low impact – lines to be aligned with existing NamPower servitudes and roads
Topography of the site require the minimum civil/groundworks and natural contours and surface drainage to be maintained
Low impact – existing surface drainage system to be used
Cable trenches 1m deep and be backfilled and compacted to standard in order to prevent erosion
Low impact – soil erosion to be minimized
Lines to be constructed by timber poles, 80m spacing, Wolf bare conductor, fitted in HLPCD staggered delta formation with with a minimum of 9m ground clearance
Low impact as giraffes roaming the area will clear the lines at this height
GREEN EARTH Environmental Consultants 4
There are giraffes roaming on the farm Powerline to be constructed at 9 m height to prevent the risk of the electrocution of the giraffes
Powerline bird interaction The lines will be visible (fitted with bird flight divertors) in order to prevent birds from flying into the lines
Road and powerline crossings to allow for special clearance from the necessary authorities based on actual site survey data and profiling
Low impact – to be done in accordance with specification and requirements with approval of affected authorities
The PV Plant and transfer station area will be maintained and kept clean from bush/shrub/tree regrowth by application of environmentally friendly herbicides and hand clearing
Low impact - a systemic, broad-spectrum glyphosate-based herbicide, glyphosate-based herbicides do have a significant risk for human or environmental health when the product label is not properly followed
Renewable source of energy which will reduce operation costs of NPI
Positive impact
Less pressure on NamPower network Positive impact
Some of the positive impacts associated with the proposed solar plant that is intended by
Namib Poultry (Pty) Ltd are the generation of energy, making use of a renewable source
of energy and the creation of employment through the construction of infrastructure and
operations.
The negative impacts associated with the proposed construction and operation on the
project site are the impact on the vegetation, the natural surface drainage systems, noise
and dust from the construction, the transmission of diseases from people or to people
involved in operations and the loss of farmland. Mitigation measures will be provided that
can control the extent, intensity and frequency of these named impacts in order not to
have substantial negative effects or results.
The type of activities that will be carried out on the site does not negatively affect the
amenity of the locality and the activities do not adversely affect the environmental quality
of the area. None of the potential impacts identified are regarded as having a significant
impact to the extent that the proposed project should not be allowed. However, the
operational activities further on need to be controlled and monitored by the assigned
managers and the proponent (Namib Poultry (Pty) Ltd).
The Environmental Impact Assessment which follows upon this paragraph was conducted
in accordance with the guidelines and stipulations of the Environmental Management Act
(No 7 of 2007) meaning that all possible impacts have been considered and the details
are presented in the report.
Based upon the conclusions and recommendations of the Environmental Impact
Assessment Report and Environmental Management Plan following this paragraph the
Environmental Commissioner of the Ministry of Environment and Tourism is herewith
requested to:
1. Accept the Environmental Impact Assessment;
2. Approve the Environmental Management Plan;

1. INTRODUCTION Green Earth Environmental Consultants have been appointed by Namib Poultry (Pty)
Ltd to attend to and complete an Environmental Impact Assessment (EIA) and
Environmental Management Plan (EMP) in order to obtain an Environmental Clearance
Certificate for the proposed construction of a 4 Megawatt Photovoltaic Plant and Overhead
Power Lines on a Portion of Portion 7 of Farm Klein Okapuka No. 51, Khomas Region as
per the requirements of the Environmental Management Act (No. 7 of 2007) and the
Environmental Impact Assessment Regulations (GN 30 in GG 4878 of 6 February 2012).
The Environmental Management Act (No. 7 of 2007) and the Environmental Impact
Assessment Regulations (GN 30 in GG 4878 of 6 February 2012) stipulates that an
Environmental Impact Assessment (EIA) report and management plan is required as the
following 'Listed Activities' are involved:
ENERGY GENERATION, TRANSMISSION AND STORAGE ACTIVITIES
1. The construction of facilities for -
(a) the generation of electricity;
(b) the transmission and supply of electricity;
The Environmental Impact Assessment below contains information on the proposed
project and the surrounding areas, the proposed operations and activities, the applicable
legislation to the study conducted, the methodology that was followed, the public
consultation that was conducted, and the receiving environment’s sensitivity, any potential
ecological, environmental and social impacts.
2. TERMS OF REFERENCE
The proponent (Namib Poultry (Pty) Ltd) intends to apply for an Environmental Clearance
Certificate for the construction of a 4-Megawatt Photovoltaic Plant and Overhead Power
Lines on a Portion of Portion 7 of Farm Klein Okapuka No. 51, Khomas Region. To be
able to implement the project, an Environmental Impact Assessment is required. For the
Environmental Impact Assessment, Green Earth Environmental Consultants followed the
terms of reference as stipulated under the Environmental Management Act.
The aim of the environmental impact assessment was:
- To comply with Namibia’s Environmental Management Act (2007) and its
regulations (2012);
- To ascertain existing environmental conditions on the site to determine its
environmental sensitivity;
- To inform I & APs and relevant authorities of the details of the proposed operations
and to provide them with an opportunity to raise issues and concerns;
- To assess the significance of issues and concerns raised;
- To compile a report detailing all identified issues and possible impacts, stipulating
the way forward and identify specialist investigations required;
- To outline management guidelines in an Environmental Management Plan (EMP)
to minimize and/or mitigate potentially negative impacts.
GREEN EARTH Environmental Consultants 12
The tasks that were undertaken for the Environmental Impact Assessment included the
evaluation of the following: climate, water (hydrology), vegetation, geology, soils, social,
cultural heritage, groundwater, sedimentation, erosion, biodiversity, sense of place, socio-
economic environment, health, safety and traffic.
The EIA and EMP from the assessment will be submitted to the Environmental
Commissioner for consideration. Environmental Clearance will only be obtained (from the
DEA) once the EIA and EMP has been examined and approved for the listed activity. The
public consultation process as per the guidelines of the Act has been followed.
The methods that were used to assess the environmental issues and alternatives included
a desk top study, the collection of data on the project site and area from the proponent
and identified stakeholders. Consequences of impacts were determined in five categories:
nature of project, expected duration of impact, geographical extent of the event, probability
of occurring and the expected intensity.
All other permits, licenses or certificates that are further on required for the operation of
the proposed project still needs to be applied for by the proponent.
3. BACKGROUND INFORMATION ON PROJECT
3.1. PROJECT LOCATION AND DESCRIPTION
The Photovoltaic Plant (PV) will be located on a portion of Portion 7 of Farm Klein Okapuka
No. 51, Khomas Region, ±30km to the north of Windhoek, to the west of the B1 National
Road. The PV Plant is required to supplement the electricity requirements of NPI’s
operations. The PV Plant will be linked to the various NPI operations by ±3km of 11kV
overhead powerlines. The PV Plant will be developed over 2 Phases. Phase 1 will have
the capacity of 2 Megawatt, and it is the intension to do a Phase 2 development of the
same capacity in the following 3 years to cater for the additional requirements of the
Proponent’s operations. Both Phases of the PV Plant and Transfer Station will be
constructed on an area of approximately 16ha that have already been cleared from
vegetation.
The PV Plant and Transfer Station will include the Solar Feeder Lines and overhead lines.
The timber poles that will be used for the overhead lines will be 11m high with 9m ground
clearance. The lines will be constructed at 80m spacing, Wolf bare conductor (a special
type of aluminum conductor steel reinforced) and fitted in HLPCD (staggered delta
formation). PV modules will be fitted on aluminum/steel single axis solar tracker for
optimized energy gain. The solar modules are typically mounted 1.2m above ground for
reduced heat reflection. The proposed line routes will be 3 km 11kV overhead lines from
the proposed PV plant to the existing Poultry Substation supplied from NamPower’s bulk
supply.
The road and power line crossings will allow for special clearance from the necessary
authorities based on site survey data and profiling. The line route for the generator feeder
is west of the existing 132kV (operated at 66kV) monopole transmission line, just outside
GREEN EARTH Environmental Consultants 13
the 30m NamPower servitude. Phase 1 and 2 of the PV Park is aligned with the current
power lines, farm boundary and road reserve. The area mentioned shall represent no less
than 16 ha for the PV park c/w transfer station. The entire area that will accommodate the
PV Park will be fenced off with a security fence to prevent human and animal interference
with 24 hour guarded access control.
The proposed site for the PV Plant has previously been cleared of vegetation. The
vegetation on the site consist mainly of intruder bush (see paragraph on biodiversity and
vegetation). Civil interference to the soil during site preparation and construction will be
kept to a minimum, only some grading and first line leveling will take place, but natural
contours and run-off will be respected and maintained. Cable trenches will be up to 1m
deep and will be backfilled and compacted to standard in order to prevent erosion. The
park area will be maintained and kept clean from bushes/shrubs/trees re-growth by
application of herbicides and hand clearing. See below locality of project site as well as
the alignment of the overhead power lines.

The lines will be visible (fitted with bird flight divertors) in order to prevent birds from flying
into the lines. There will be a 15-meter-wide servitude on both sides of the line. There
will be only a limited amount of vegetation clearance and site leveling required for the
operations to be carried out for the construction of the solar plant. Namib Poultry already
holds a de-bushing permit however protected trees will be kept and not harmed in the
process. Jobs will be created in the construction and operation phase. The site will be
fenced in with an electrical fence to prevent people and animals from entering the site. A
security guard will also be appointed to protect the site. A small guard house will be
erected. It is the intension to sell electricity to 3rd parties if additional electricity is produced.
GREEN EARTH Environmental Consultants 19
The solar plant will produce no radiation or chemicals that can be harmful to the
environment.
3.2. PV SOLAR ENERGY FACILITY Typical solar panels capture light energy from the sun to generate electricity through a
process known as the PV effect, where light energy energize electrons to produce
electricity. Conventional PV technology generates electricity by converting solar radiation
energy into a direct current which needs to be converted to an alternating current to
connect to the grid (Origins of Solar Energy, 2012).

The potential impacts of the solar plant are listed below. The impacts with the mitigation
measures are described in the Environmental Management Plan.
Potential Impacts:
Disturbance of flora and fauna
Impact on agricultural resources
Impacts on surface water resources
Stormwater impacts (including sedimentation and erosion)
Visual impacts
Social impacts (including economic development,
employment rates and types, HIV infection rates, theft, etc.)
Noise and dust pollution
Impact on energy production
Increased traffic
Storage of hazardous substances on site
Impact of construction waste
The disposal of end-of-life solar panels
4. BULK SERVICES AND INFRASTRUCTURE
4.1. ACCESS AND INTERNAL ROADS
The project site is located on Portion 7 of Farm Klein Okapuka No. 51, about 30 km north
of Windhoek directly west of the B1 Highway to Okahandja. The project site access is to
the western side of the B1 Highway. The access road is a gravel road leading from the
newly constructed intersection with the B1 Highway onto the site and connecting all the
operations and activities of Namib Poultry. The gravel road is maintained by Namib
Poultry. The existing roads are sufficient for the purpose of the operations and no new
roads have to be created on site.
4.2. WATER SUPPLY
Water requirements to the site are supplied from 2 sources:
• By NamWater via a pipeline from the main water line which supplies water from
the Von Bach Dam to Windhoek. The initial agreement between Namib Poultry
and NamWater made provision for and allocation of 45 000m³/month or 540
000m³/year. Currently NPI’s average monthly water consumption amounts to 28
500m³/month.
• About 120m³/day is extracted from boreholes.
GREEN EARTH Environmental Consultants 22
The savings between the NamWater allocation and current usage are achieved through
the onsite treatment of water and the reuse thereof. Currently 96% of the water used in
the meat processing plant is reclaimed. The existing water sources are enough to cater
for the requirements of the PV Plant.
4.3. ELECTRICITY RETICULATION
Electricity is obtained from NamPower with backup generators that are used during power
failures. The proposed PV Plant will be used to supplement the NamPower supply. The
Proponent also intends to construct and operate a biodigester to generate biogas from the
chicken manure generated from the chicken rearing operations which will supplement their
electrical requirements. An EIA and EMP for the proposed biodigester have already been
submitted to the MET for consideration and to obtain an Environmental Clearance.
Figure 12: Power Station transferring Electricity
4.4. SEWAGE TREATMENT AND DISPOSAL
Household sewerage from people working and residing on the PV Plant will be collected
from the ablution facilities in a sealed underground tank. This sewerage is then collected
in a tanker and taken to the wastewater treatment plant for treatment and recycling to
ensure reuse of more water. A “honey sucker” collects the sewage and transport it to the
treatment plant.
4.5. SOLID WASTE DISPOSAL/REFUSE REMOVAL
Construction waste will be disposed of at approved City of Windhoek sites. Household
waste generated at the PV Plant will be sorted into the different recyclables and stored on
site and then collected on site by an approved private waste management company (Rent-
A-Drum) from where it is taken to their recycling facility for processing and disposed of at
the approved waste disposal/landfill site.
GREEN EARTH Environmental Consultants 23
5. APPROACH TO THE STUDY
The assessment included the following activities:
a) Desktop sensitivity assessment
Literature, legislation and guidance documents related to the natural environment and land
use activities available on the site and area in general were reviewed to determine
potential environmental issues and concerns.
b) Site assessment (site visit)
A site visit was conducted on 7 November 2019 at 16:00 when the immediate surrounding
area was assessed. Further site visits to investigate the environmental parameters on site
to enable further understanding of the potential impacts on site also took place.
c) Public participation
The public were invited to give input, comments and opinions regarding the proposed
project. Notices were placed in two local newspapers (New Era of 16 and 23 October and
the Namibian of 17 and 24 October 2019) on two consecutive weeks inviting the public to
participate and provide comments on the proposed project. Copies of the newspaper
notices are attached to this report. The closing date for any questions, comments, inputs
or information on the Newspaper Notices was 12 November 2019. The closing date for
comments on the Background Information Document was 8 November 2019. A public
meeting took place on 7 November 2019 at 15:00 at the NPI Boardroom. The attendance
register of the meeting are attached to this document. None of the public attended the
meeting.
d) Scoping
Based on the desk top study, site visits and public participation, the environmental impacts
were determined in five categories: nature of project, expected duration of impact,
geographical extent of the event, probability of occurring and the expected intensity. The
findings of the scoping have been incorporated in the environmental impact assessment
report below.
e) Environmental Management Plan (EMP)
To minimize the impact on the environment, mitigation measures have been identified to
be implemented during planning, construction and implementation. These measures have
been included in the Environmental Management Plan to guide the planning, construction
and operation of the solar plant which can also be used by the relevant authorities to
ensure that the project is planned, developed and operated with the minimum impact on
the environment.
GREEN EARTH Environmental Consultants 24
6. ASSUMPTIONS AND LIMITATIONS
It is assumed that the information provided by the proponent (Namib Poultry (Pty) Ltd),
GSFA – G.S. Fainsinger & Associates – Mr Volker Rugheimer (the Consulting Engineers
appointed by NPI) and other relevant parties are accurate. Alternative sites were not
evaluated as the proposed site is the site owned by the proponent and because the site is
also located in close proximity of the Namib Poultry Substation into which the electricity
generated by the PV Plant will be feed. The site was visited several times and any
happenings after this are not mentioned in this report. (The assessment was based on
the prevailing environmental conditions and not on future happenings on the site.)
However, it is assumed that there will be no significant changes to the proposed project,
and the environment will not adversely be affected between the compilation of the
assessment and the implementation of the proposed activities.
7. ADMINISTRATIVE, LEGAL AND POLICY REQUIREMENTS
To protect the environment and achieve sustainable development, all projects, plans,
programs and policies deemed to have adverse impacts on the environment require an
EIA according to Namibian legislation. The administrative, legal and policy requirements
to be considered during the Environmental Assessment for the proposed solar plant are
the following:
• The Namibian Constitution
• The Environmental Management Act (No. 7 of 2007) and Regulations (2012)
• Other Laws, Acts, Regulations and Policies
THE NAMIBIAN CONSTITUTION
Article 95 of Namibia’s constitution provides that: “The State shall actively promote and
maintain the welfare of the people by adopting, inter alia, policies aimed at the following:
Management of ecosystems, essential ecological processes and biological diversity of
Namibia and utilization of living natural resources on a sustainable basis for the benefit of
all Namibians, both present and future; in particular, the Government shall ensure that the
natural resources and features like rivers, plants, trees as well as water resources are
protected and sustained by providing measures against destroying the environment and
the natural resources. This article recommends that a relatively high level of environmental
protection is called for in respect of activities which might impact on these natural
resources. Article 144 of the Namibian Constitution deals with environmental law and it
states:
“Unless otherwise provided by this Constitution or Act of Parliament, the general rules of
public international agreements binding upon Namibia under this Constitution shall form
part of the law of Namibia”. This article incorporates international law, if it conforms to the
Constitution, automatically as “law of the land”. These include international agreements,
conventions, protocols, covenants, charters, statutes, acts, declarations, concords,
exchanges of notes, agreed minutes, memoranda of understanding, and agreements
(Ruppel & Ruppel-Schlichting, 2013). It is therefore important that the international
agreements and conventions are considered (see section 4.9).
GREEN EARTH Environmental Consultants 25
In considering the environmental rights, the proponent, Namib Poultry (Pty) Ltd, should
consider the following in devising an action plan in response to these articles:
• Implement a “zero-harm” policy, which would guide decisions and operations.
• Ensure that no management practice or decision result in the degradation of future
natural resources.
• Take a decision on how this part of the Constitution will be implemented as part of
the Environmental Control System (ECS).
ENVIRONMENTAL MANAGEMENT ACT (NO. 7 OF 2007) AND REGULATIONS (2012)
The Environmental Impact Assessment Regulations (GN 30 in GG 4878 of 6 February
2012) of the Environmental Management Act (No. 7 of 2007) that came into effect in 2012
requires/recommends that an Environmental Impact Assessment and an Environmental
Management Plan (EMP) be conducted for the following listed activities to obtain an
Environmental Clearance Certificate:
ENERGY GENERATION, TRANSMISSION AND STORAGE ACTIVITIES
1. The construction of facilities for -
(a) the generation of electricity;
(b) the transmission and supply of electricity;
Cumulative impacts associated with the project must be included as well as public
consultation. The Act further requires all major industries and developers to prepare waste
management plans and present these to the local authorities for approval.
The Act, Regulations, Procedures and Guidelines have integrated the following
sustainability principles. They need to be given due consideration, particularly to achieve
proper waste management and pollution control:
Cradle to Grave Responsibility
This principle provides that those who handle or manufacture potentially harmful products
must be liable for their safe production, use and disposal and that those who initiate
potentially polluting activities must be liable for their commissioning, operation and
decommissioning.
Precautionary Principle
It provides that if there is any doubt about the effects of a potentially polluting activity, a
cautious approach must be adopted.
The Polluter Pays Principle
A person who generates waste or causes pollution must, in theory, pay the full costs of its
treatment or of the harm, which it causes to the environment.

Public Participation and Access to Information
In the context of environmental management, citizens must have access to information
and the right to participate in decisions making.
CONCLUSION AND IMPACT
The proposed solar plant has been assessed in terms of the Environmental Management
Act (No. 7 of 2007) and the Regulations (2012). From the assessment, it can be concluded
that the activities will have impacts on the prevailing environment but that the negative
impacts can be sufficiently mitigated and managed by following the Environmental
Management Plan which is part of this document.
Other Acts, Policies and guidelines will also be consulted to ensure that the project is
constructed and operated in accordance with Namibian and International Legislation and
guidelines.

CONCLUSION AND IMPACT
Green Earth Environmental Consultants believe the above administrative, legal and policy
requirements which specifically guide and govern the development at the proposed project
site will be followed and complied with in the assessment of the activity. A flowchart
indicating the entire EIA process is shown in the Figure below.

8. AFFECTED RECEIVING ENVIRONMENT
8.1. BIODIVERSITY AND VEGETATION
The vegetation on Farm Klein Okapuka where the solar plant will be constructed and
operated forms part of the Tree and Shrub Savannah Biome, specifically the Highland
Savannah. The project site is showing evidence of some human inference namely
informal tracks are present on some areas of the site and a few gravel roads are present
on the site and the vegetation was cleared.
Figure 14: Biomes of Namibia (Atlas of Namibia, 2002)
During the site visit, various species of trees/shrubs were identified in the proposed project
area. Of these, 6 species (Acacia erioloba, Albizia anthelmintica, Boscia albitrunca,
Ozoroa crassinervia, Searsia lancea & Ziziphus mucronata) are protected under Forestry
legislation with 1 species also being “near-endemic” (Ozoroa crassinervia).
The most important tree/shrub species expected from the general area are the various
protected species and species of conservation concern and include Commiphora dinteri
(endemic), Cyphostemma bainesii (endemic, NC), Cyphostemma currorii (NC) and
Heteromorpha papillosa (endemic). All aloe species are protected in Namibia and other
species potentially occurring in the general area are Aloe hereroensis and Aloe zebrina
(Rothmann, 2004). None of the species are exclusively associated with the project area.
Project Site area
GREEN EARTH Environmental Consultants 32
Figure 15: Limited vegetation or trees present on site
Small birds and insects were observed during the site visit. The natural characteristics of
the project site namely the vegetation clearance and the destruction of habitats is expected
to further on have a low impact on the environment before the mitigation measures are
taken and after the mitigation measures are taken, the impact will be very low.
8.2. CLIMATE
No specific climate data is available for the project site. Farm Okapuka and surroundings
in general is characterized with a semi-arid highland savannah climate typified as very hot
in summer and moderate dry in winter. The highest temperatures are measured in
December with an average daily temperature of maximum 31ºC and a minimum of 17ºC.
The coldest temperatures, conversely, are measured in July with an average daily
maximum of 20ºC and minimum 6ºC (Weather - the Climate in Namibia, 1998 – 2012).
The area therefore has low frost potential.
Rainfall in the form of thunderstorms is experienced in the area during the summer months
between October and April. The annual average rainfall for the area is 350mm to 400mm
however the average evaporation rate is 3 400mm a year (Weather - the Climate in
Namibia, 1998 – 2012). Over 70% of the rainfall occurs in the summer months’ period
between November and March. Rainfall in the area is typically sporadic and unpredictable
however the average highest rainfall months are January to March.
Wind is expected to prevent the spread of any nuisance namely noise and smell. The
predominant wind in the region is easterly with westerly winds from September to
December (Weather - the Climate in Namibia, 1998 – 2012). Extreme winds are
experienced in the months of August and September and thus significant wind erosion on
disturbed areas is visible.

8.3. GEOLOGY AND SOILS The solar plant of Namib Poultry (Pty) Ltd is in the Khomas Trough on a geological area
classified as Damara Supergroup and Gariep Complex. See Map below:
8.4. GEOHYDROLOGICAL CHARACTERISTICS OF THE SITE
The bedrock geology of the area consists primarily of highly deformed rocks of the Kuiseb
Formation rocks of the Swakop Group. The dominant lithologies are metagreywacke and
mica schist.
Figure 16: Temperatures in Namibia
Project Site
Figure 17: Geology of Namibia (Atlas of Namibia Project, 2002)
Project Site
GREEN EARTH Environmental Consultants 34
Structures present in the larger area are mainly north-south faults and joint systems. The
north-south fault systems are less developed in the micaceous lithologies of the Kuiseb
Formation rocks, as the mica schist undergoes plastic deformation rather than brittle
fracturing. No faults are mapped within the operations area.
Some geological observations made during the field visit are:
- The schist is generally more massive, and foliation is not very well developed.
- Some north-west – south-east striking joints are cross-cutting the schist.
- Quite a lot of quartz veins are present.
- The area is largely covered by a thin “quartz-pebble mulch” covering much of the
soil horizon.
To understand the occurrence of groundwater and the potential pollution impact of the
proposed project on groundwater, it is necessary to describe the prevailing
geohydrological conditions, and to understand some of the fundamental geohydrological
concepts. The predominant geology is the determining factor in the behaviour and
characteristics of the geohydrological environment. The underlying geology is primarily
schist, which is considered having a low groundwater potential and low risk of groundwater
contamination.
Along drainage channels and rivers, alluvium may be found which have a moderate to
high groundwater potential, with an associated higher risk of groundwater pollution. The
main aquifer type found in the area is secondary fractured aquifers hosted in the mica
schist of the Kuiseb Formation, with perceived limited (small) aquifers formed along the
ephemeral river courses that are associated with river alluvial, or where groundwater
recharge takes place during flood events.
Figure 18: Groundwater basins and rock types
Project Site
GREEN EARTH Environmental Consultants 35
Schist, being a naturally poor host of groundwater, acts as an aquiclude, or when hosting
groundwater, at best as an aquatard. The weathering product of schist is clayey material,
which also is not favourable for transmitting groundwater. The field observations made
regarding some of characteristics of the schist, namely its massive nature together with
cross-cutting joints, is important in that:
1. The massive schist will be even more impervious than well-foliated schist, thereby
further reducing the potential for groundwater flow.
2. The joints, if open at depth, will have higher transmissivity in relation to the matrix rock
transmissivity, thus resulting in higher percolation rates and flow rates of groundwater in
the joints.
3. If the quartz veins are a result of quartz intrusion from depth, these veins can act as
preferential flow paths, and it can also store significant quantities of groundwater, thus it
can potentially act as good secondary aquifers.
It must however be borne in mind that, even if flow rates can be higher in certain parts of
the schist, the rock type in general is at best an aquatard. Furthermore, the
“geohydrologically better” portion of the schist in relation to the “geohydrologically poor”
portion of the schist is most likely negligibly small. The most significant negative aspect of
this higher transmissivity characteristic in joint zones is that pollutants can enter and
disperse through such joint zones much easier. At the same time however, it will be
extremely difficult to remove or abstract any pollutant from the schist due to its over-all
poor transmissivity.
The information suggests that the area in general has poor groundwater potential and the
predominant geology in the area results in very little risk of groundwater contamination,
unless pollutants end up in geological structures acting as preferential groundwater flow
paths (faults or open joints) or along the river courses where groundwater flow in the
alluvial sediments will be higher. Under such conditions the transmissivity is higher;
therefore, the potential to easily transmit pollutants can also be moderate to high.
The Hydrogeological Map of Namibia shows that the study area falls in a zone of rock
bodies with little groundwater potential (generally low; locally moderate potential) in an
area of metamorphic rocks.
GREEN EARTH Environmental Consultants 36
Figure 19: Hydrogeological Map of Namibia (Geological Survey of Namibia, 2015)
It can therefore be concluded that the geological and geohydrological settings limit the flux
of groundwater between different groundwater bodies or aquifers in the schist bedrock,
thus limiting the movement of potential pollutants within this rock type; limit the probability
that groundwater utilisation in one area will adversely affect groundwater availability in
surrounding areas, and could result in higher flux within homogenous layers (Geological
Survey of Namibia, 2015).
8.5. GROUNDWATER
Ground water pollution can have a negative effect on the receiving environment as well
as on the surrounding areas. Soil, geological and geo-hydrological characteristics of the
site indicate that the potential significance that water resources will be damaged is very
small. For ground water to be contaminated, large amounts of oil or fuel will have to seep
through the soil over a period. The Water Resource Management Act (No. 24 of 2004)
stipulates that even the potential sources of pollution still requires attention namely
planning, controlling and managing the possible pollution of the receiving environment as
the cumulative impact of many environmentally harmful incidents will in the long run have
a detrimental impact on the downstream water sources, resources and users. With
precautionary measures that are in place, groundwater contamination is easily prevented,
and the proposed operations are not expected to have a detrimental impact on water
resources in the area.
8.6. SURFACE WATER Surface water flow in a catchment is largely determined by rainfall (quantity and intensity),
potential evapotranspiration and catchment relief. A drainage system comprises all the
elements of the landscape through which or over which water travels within that drainage
basin. These elements include the soil, vegetation growing on it, geological materials
underlying the soil, stream channels carrying surface water and the zones where water is
held in the soil and moves below the surface. It also includes constructed elements such
Project Site
GREEN EARTH Environmental Consultants 37
as pipes and culverts, cleared and compacted land surfaces, and pavement and other
impervious surfaces unable to absorb water. The hydrology of a region is thus
characterised by the collection, movement and storage of water through a drainage basin.
Alteration of a natural drainage basin through for instance urbanisation can impose
dramatic changes in the movement and storage of water. These changes can have
negative impacts on other parties that use water for industrial, domestic and livestock
watering purposes in the immediate vicinity or downstream.
The major potential impacts of the proposed solar plant on surface water primarily relates
to the generation of increased run-off, water quality and possible pollution: Increased
storm water and run-off due to vegetation removal during construction. Potential pollution
can be due to storage, handling or spillage of hazardous substances and chemicals,
potential pollution due to transportation and potential pollution due to sewage disposal and
storm water.
Erosion and sedimentation could result from soils that are being exposed during the
clearing of land, grading and the installation of underground utilities namely water pipes
or related infrastructure, etc. Erosion and sedimentation could further result in the
degradation of habitats in the rainy season. Severe impacts may occur if erosion and
sedimentation impacts are not taken into consideration namely loss of valuable topsoil,
vegetation and habitat. The infrastructure that will be constructed on the site is believed
to have a limited impact on erosion and sedimentation since drainage channels will be
kept open and will be incorporated in the operations.
8.7. SOCIAL-ECONOMIC COMPONENT
The proposed solar plant will have a positive impact on the socio-economic environment
because of employment creation and the provision of energy. Apart from the proponent’s
intension to make a profit out of the proposed activities, advantages to the area are
numerous. The proposed operations will create the need for more business activities such
as building maintenance, vehicle maintenance and additional support for existing
businesses etc.
The proposed project will create semi-permanent and permanent employment. Since
most land use in and around the area is characterised by farming, manufacturing, abattoir
and bakery related activities, the operations will not have a negative impact on the
neighbours or the surrounding areas.
8.8. CULTURAL HERITAGE
The proposed project site is not known to have any historical significance prior to or after
Independence in 1990. The specific area does not have any National Monuments and the
specific site has no record of any cultural or historical importance or on-site resemblance
of any nature. No graveyard or related article was found on the site.
GREEN EARTH Environmental Consultants 38
8.9. SENSE OF PLACE
The proposed solar plant of Namib Poultry (Pty) Ltd will be located on a Portion of Portion
7 of Farm Okapuka outside Windhoek. The proposed solar plant will not have a
large/negative impact on the sense of place in the area. An untidy or badly managed site
can detract from the ecological well-being and individuality of the area. Unnecessary
disturbance to the surroundings could be caused by poorly planned or poorly managed
operational activities. The site should be kept neat and clean where possible. Vegetation
should not be removed or harmed if not necessary since it covers topsoil which prevents
erosion. Noise and dust should be limited in the operational phase.
Figure 20: Sense of Place
8.10. HEALTH
The safety, security and health of the labour force, employees and neighbours are of great
importance, workers should be orientated with the maintenance of safety and health
procedures and they should be provided with PPE (Proper Protective Equipment). A
health and safety officer should be employed to manage, coordinate and monitor risk and
hazard and report all health and safety related issues in the workplace. The introduction
of external workers into the area is sometimes accompanied with criminal activities posing
security risks for neighbors. However, the proponent will take certain measures to prevent
any activity of this sort. The welfare and quality of life of the neighbours and workforce
needs to be considered for the project to be a success on its environmental performance.
Conversely, the process should not affect the overall health of persons related to the
project including the neighbours.
8.11. ROAD INFRASTRUCTURE
Development is usually associated with an increase in vehicles to and from the site since
worker busses, delivery vehicles and trucks are needed for construction and operations.
It is important that all vehicle drivers be informed of their potential impact on the
environment and on the roads, and that the necessary measures should be taken to
prevent any accidents as a result of increased traffic.
GREEN EARTH Environmental Consultants 39
9. ASSESSMENT AND EVALUATION
Development, no matter the type or scale, within an un-spoilt or even altered natural
environment, is bound to have an impact or further impacts on the environment. This
assessment concentrates on both the positive and negative impacts of the proposed solar
plant. The positive impacts are in terms of energy/financial gain, employment creation and
making use of sustainable power. The following assessment methodology will be used to
examine each impact identified, see Table below:

The darker grey shaded boxes indicate the potential impact or interaction from the activity
on the environment. The impacts on the receiving environment are discussed in the
paragraphs below.
9.1. POTENTIALLY SIGNIFICANT IMPACTS
From the site assessment and interaction with I&APs, the potentially significant impacts
listed below were identified. Many of these impacts can be adequately addressed through
the implementation of appropriate mitigation and management measures.
9.1.1. AIR QUALITY IMPACTS
During the construction phase it is expected that the main sources of impact will result due
to the construction of access roads and the PV plant. These predicted impacts cannot be
quantified, primarily due to the lack of detailed information related to scheduling and
positioning of construction related activities which will only come out in the feasibility study.
Instead a qualitative description of the impacts was done. It involved the identification of
possible sources of emissions and the provision of details related to their impacts.
Construction is commonly of a temporary nature with a definite beginning and end.
Construction usually consists of a series of different operations, each with its own duration
and potential for dust generation. Dust emission will vary from day to day depending on
the phase of construction, the level of activity, and the prevailing meteorological
GREEN EARTH Environmental Consultants 42
conditions. Dust will be generated significantly due to the dry conditions and the sandy
texture of the soils in the project area.
The following activities could potentially generate dust during construction at the site:
Transportation of materials
Scraping
Debris handling
Land clearing for infrastructure
Creation and Grading of Access Roads
Access roads are constructed by the removal of overlying topsoil, whereby the exposed
surface is graded to provide a smooth compacted surface for vehicles to drive on. Material
removed is often stored in temporary piles close to the road edge, which allows for easy
access once the road is no longer in use, whereby the material stored in these piles can
be re-covered for rehabilitation purposes. Often however, these unused roads are left as
is in the event that sections of them could be reused at a later stage.
A large amount of dust emissions is generated by vehicle traffic over these temporary
unpaved roads. Substantial secondary emissions may be emitted from material moved
out from the site during grading and deposited adjacent to roads. Passing traffic can thus
re-suspend the deposited material. To avoid these impacts, material storage piles
deposited adjacent to the road edge should be vegetated, with watering of the pile prior to
the establishment of sufficient vegetation cover. Piles deposited on the verges during
continued grading along these routes should also be treated using wet or chemical
suppressants depending on the nature and extent of their impacts.
A positive correlation exists between the amount of dust generated (during vehicle
entrainment) and the silt content of the soil as well as the speed and size of construction
vehicles. Additionally, the higher the moisture content of the soil, the lower the amount of
dust generated. The periodic watering of these road sections will aid in the reduction of
dust generated from these sources. Cognisance should be taken to increase the watering
rate during high wind days and during the summer months when the rate of evaporation
increases.
Preparation of site for and construction of the PV Plant and Transfer Station
(supporting infrastructure)
Removal of material usually takes place with a bulldozer, extracted material is then stored
in piles for later use during rehabilitation procedures. Fugitive dust is generated during the
extraction and removal of overlying material, as well as from windblown dust generated
from cleared land and exposed material stockpiles. Dust problems can also be generated
during the transportation of the extracted material, usually by truck, to the stockpiles. This
dust can take the form of entrainment from the vehicle itself or due to dust blown from the
back of the trucks during transportation.
To avoid the generation of unnecessary dust, material drop height should be reduced and
material storage piles should be protected from wind erosion. This can take the form of
GREEN EARTH Environmental Consultants 43
wind breaks, water sprays or vegetation on piles. All stockpiles should be damped down,
especially during dry weather.
It should be noted that emissions generated by wind are also dependent on the frequency
of disturbance of the erodible surface. Each time material is added to or removed from a
storage pile or surface, the potential for erosion by wind is restored. Dust created during
the transportation can be limited by watering the road sections that are being used and by
either wetting the material being transported or covering the back of the trucks, to limit the
windblown dust from the load.
9.1.2. WILDLIFE INTERACTIONS
Solar plants are relatively new and their effects on biodiversity have been scarcely
documented. Impacts are associated with the habitat transformation and wildlife mortality.
Wildlife can be destructive, and it is advisable to protect the solar plant with electrical
fences to keep the animals away.
Data on the avifauna and electricity interactions shows some species in the projects area
may be affected as follows:
Powerline & Bird Interactions
Red Data Species and nest-problem species (1820BB) - at most 15 species have been
found to be affected by electricity infrastructure in the project area. The transmission line
to be constructed between the PV Plant and Transfer Station to the substation will
probably have the largest impact. The lines will be visible (fitted with bird flight divertors)
in order to prevent birds from flying into the lines.
Powerline and Giraffes interactions
There are a group of Giraffes roaming on the farm. To prevent the Giraffes from interacting
with the powerlines it will be constructed with a ground clearance of 9m.
Potential impacts arising from habitat damage
The following birds are either present or moving through the project area: African Fish-
Eagle (V), African Marsh-Harrier (E), African Skimmer (V), Bateleur (E), Black-winged
Pratincole (NT), Lappet-faced Vulture (V), Marabou Stork (NT), Martial Eagle (E), Rufous-
bellied Heron (E), Tawny Eagle (E), White-backed Vulture (E) and White-headed Vulture
(V) (Chris Brown). The habitats of these birds could be damaged by the proposed
activities. Care should be taken to avoid damage to the habitats of these birds.

Faults caused by nests
Birds make nests on the lines which cause faults in the systems. Care should be taken to
make sure birds avoid making nests on the lines. Various trees are in the area that can
be used as structures for birds to make nests.
9.2. IMPACTS DURING CONSTRUCTION
Some of the impacts that the solar plant will have on the environment includes water will
be used for the construction and operational activities, electricity will be used, and
wastewater will be produced on the site that will have to be handled.
9.2.1. WATER USAGE
Water is a scarce resource in Namibia and therefore water usage should be monitored
and limited in order to prevent unnecessary wastage. The proposed solar plant will make
use of water in its construction phase and limited in the operational phase for maintenance.

9.2.2. ECOLOGICAL IMPACTS
The proposed solar plant will be constructed in a semi disturbed natural area which is
sparsely covered with vegetation. Special care should be taken to limit the destruction or
damage of the vegetation. However, impacts on fauna and flora are expected to be
minimal. Disturbance of areas outside the designated working zone is not allowed.

9.2.3. DUST POLLUTION AND AIR QUALITY
Dust generated during the transportation of building materials; construction and
installation of bulk services, and problems thereof are expected to be low and site specific
due to the nature of the top soils. Dust is expected to be worse during the winter months
when strong winds occur. Release of various particulates from the site during the
construction phase and exhaust fumes from vehicles and machinery related to the
GREEN EARTH Environmental Consultants 45
construction of bulk services are also expected to take place. Dust is regarded as a
nuisance as it reduces visibility, affects the human health and retards plant growth.
It is recommended that regular dust suppression be included in the construction activities,
when dust becomes an issue. No unnecessary revving of engines or operation of vehicles
is allowed. In general, the servicing of these extensions is envisaged to have minimal
impacts on the surrounding air quality.

9.2.4. NOISE IMPACT
An increase of ambient noise levels at the proposed site is expected due to the
construction activities. Noise pollution due to heavy-duty equipment and machinery will
be generated.
It is not expected that the noise generated during construction will impact any third parties
due to the distance of the neighbouring activities. Ensure all mufflers on vehicles are in
full operational order; and any audio equipment should not be played at levels considered
intrusive by others. The construction workers should be equipped with ear protection
equipment.

9.2.5. HEALTH, SAFETY AND SECURITY
The safety, security and health of the labour force, employees and general public are of
great importance. Workers should be orientated with the maintenance of safety and health
procedures and they should be provided with PPE (Proper Protective Equipment). A
health and safety officer should be employed to manage, coordinate and monitor risk and
hazard and report all health and safety related issues in the work place.
Safety issues could arise from the earthmoving equipment and tools that will be used on
site during the construction phase. This increases the possibility of injuries and the
contractor must ensure that all staff members are made aware of the potential risks of
injuries on site. The presence of equipment lying around on site may also encourage
criminal activities (theft).
Sensitize operators of earthmoving equipment and tools to switch off engines of vehicles
or machinery not being used. The contractor is advised to ensure that the team is equipped
GREEN EARTH Environmental Consultants 46
with first aid kits and that they are available on site, always. Workers should be equipped
with adequate personal protective gear and properly trained in first aid and safety
awareness.
No open flames, smoking or any potential sources of ignition should be allowed at the
project location. Signs such as ‘NO SMOKING’ must be prominently displayed in parts
where inflammable materials are stored on the premises. Proper barricading and/or
fencing around the site especially trenches for pipes and drains should be erected to avoid
entrance of animals and/or unauthorized persons. Safety regulatory signs should be
placed at strategic locations to ensure awareness. Adequate lighting within and around
the construction locations should be erected, when visibility becomes an issue.

Care must be taken to avoid contamination of soil and groundwater. Use drip trays when
doing maintenance on machinery. Maintenance should be done on dedicated areas with
linings or concrete flooring. The risk can be lowered further through proper training of
staff. All spills must be cleaned up immediately. Excavations should be backfilled and
sealed with appropriate material, if it is not to be used further.

9.2.7. SEDIMENTATION AND EROSION
Vegetation stabilizes the area against wind erosion. Vegetation clearance and creation of
impermeable surfaces could result in erosion in areas across the proposed area. The
clearance of vegetation will further reduce the capacity of the land surface to slow down
the flow of surface water, thus decreasing infiltration, and increasing both the quantity and
velocity of surface water runoff. The proposed construction activities will increase the
number of impermeable surfaces and therefore decrease the amount of groundwater
infiltration. As a result, the amount of storm water during rainfall events could increase.
If proper storm water management measures are not implemented this will impact
negatively on the water courses close to the site.

9.2.8. GENERATION OF WASTE
This can be in a form of rubble, cement bags, pipe and electrical wire cuttings. The waste
should be gathered and stored in enclosed containers to prevent it from being blown away
by the wind. Contaminated soil due to oil leakages, lubricants and grease from the
construction equipment and machinery may also be generated during the construction
phase.
The oil leakages, lubricants and grease must be addressed. Contaminated soil must be
removed and disposed of at a hazardous waste landfill. The contractor must provide
containers on-site, to store any hazardous waste produced. Regular inspection and
housekeeping procedure monitoring should be maintained by the contractor.

Contamination of surface water might occur through oil leakages, lubricants and grease
from the equipment and machinery during the installation, construction and maintenance
of bulk services at the site. Oil spills may form a film on water surfaces in the nearby
streams causing physical damage to water-borne organisms.
Machinery should not be serviced at the construction site to avoid spills. All spills should
be cleaned up as soon as possible. Hydrocarbon contaminated clothing or equipment’s
should not be washed within 25m of any surface water body.

The placement, design and construction of the proposed solar plant should be as such as
to have the least possible impact on the natural environment. The proposed activities will
not have a large/negative impact on the sense of place in the area since it will be
constructed in a manner that will not affect the neighbouring land and it will not be visually

9.4. CUMMULATIVE IMPACTS
These are impacts on the environment, which results from the incremental impacts of the
construction and operation of the proposed solar plant when added to other past, present,
and reasonably foreseeable future actions regardless of what person undertakes such
other actions. Cumulative impacts can result from individually minor but collectively
significant actions taking place over a period. In relation to an activity, it means the impact
of an activity that in it may not become significant when added to the existing and potential
impacts resulting from similar of diverse activities or undertakings in the area.
Possible cumulative impacts associated with the proposed project includes sewer
damages/maintenance, vegetation and animal disturbance, uncontrolled traffic and
destruction of the natural environment. These impacts could become significant especially
if it is not properly supervised and controlled. This could collectively impact on the
environmental conditions in the area. Cumulative impacts could occur in both the
construction and operational phase.

10. INCOMPLETE OR UNAVAILABLE INFORMATION
The exact amount of people that will be employed will depend on the type and scope of
the solar plant activities and the number of individuals needed at each phase of the
operations. The Environmental Management Plan (EMP) will therefore include all the
possible negative effects of the project in general that could be operated on the site in
order to prevent any pollution or harmful impacts whether to neighbours or the
environment.
11. NEED AND DESIRABILITY
Work opportunities will be created, which will help alleviate poverty and enhance the
quality of life for the people involved, especially the local people. Unemployment is a
major concern in Namibia and therefore there certainly is a need for individuals to find jobs
GREEN EARTH Environmental Consultants 52
and earn a living. This project can provide employment to individuals that are skilled and
semi-skilled. The solar plant on site will make use of sunlight and convert it to energy
sources. The energy will then be used in the processes on site.
According to the information mentioned above, it is believed that there is a need and
desirability for the project. The proposed project is desirable as the study area is suitable
for the proposed operations, the activities will have a limited impact on the bio-physical
environment, enough water is available for construction and proper accesses can be
provided to the proposed operations.
Determining what the impact of the operations would be are broken down into different
categories and environmental aspects and dealt with in the Environmental Management
Plan (EMP). As per the ISO 14001 definition: an environmental aspect is an element of
an organization’s activities, products and/or services that can interact with the environment
to cause an environmental impact e.g. land degradation or land deterioration among
others, that will cause harm to the environment.
All concerns and potential impacts raised during the public participation process and
consultative meetings were evaluated. Predictions were made with respect to their
magnitude and an assessment of their significance was made according to the following
criteria:
The Nature of the activity: A solar plant will be constructed on a Portion of Portion 7 of
Farm Klein Okapuka No. 51, Khomas Region. The possible impacts that may occur are
water will be used in the construction phase, waste water will be produced that will be
handled by the proponent, land will be used for the proposed activities, few shrubs/grasses
will be removed, and general construction activities will take place.
The Probability of the impacts to occur: The probability of the above-named impacts to
occur and have a negative or harmful impact on the environment and the community is
small since the Environmental Management Plan will also guide these activities. Water
will still be used, and wastewater produced, however guidelines will be set that will ensure
the impact is minimum.
The Extent of area that the project will affect: The specific project will most likely only have
a small impact on the proposed project site itself and not on the surrounding or
neighbouring farms except for noise, traffic, machinery, roads and dust and there may be
a visual impact because of the size of the proposed operations. Therefore, the extent that
the project will have a negative impact on is not extensive.
The Duration of the project: It is estimated that the construction will take place over 1 year
however the exact duration of the activities is uncertain.
The Intensity of the project: The intensity of the project is mostly limited to the site however
for the above-named processes where the intensity of the project will be felt outside the
borders of the project site.
According to the information that was present while conducting the Environmental Impact
Assessment for the construction and operations of the solar plant, no high-risk impacts
GREEN EARTH Environmental Consultants 53
were identified and therefore it is believed that the operations will be feasible in the short
and long run. Most of the impacts identified were characterized as being of a low impact
on the receiving and surrounding environment and with mitigation measures followed, the
impacts will be of minimum significance or avoided.
12. CONCLUSION
In line with the Environmental Management Act (No 7 of 2007), Green Earth
Environmental Consultants have been appointed to conduct an Environmental Impact
Assessment for the proposed construction of a 4 Megawatt Photovoltaic Plant and
Overhead Power Lines on a Portion of Portion 7 of Farm Klein Okapuka No. 51, Khomas
Region of Namib Poultry (Pty) Ltd that may not be undertaken without an Environmental
Clearance Certificate.
The specific site has the full potential to be used for the proposed activities. It is believed
that the activities will not have a severe negative effect on the environment. It is also
believed that this project can largely benefit the economic/employment and energy/power
needs of the area.
The negative environmental impacts that may be visible in the operational phase of the
project include increases in solid waste generation and wastewater generation, can result
in an increase in traffic on the nearby roads and there can be an impact on the
occupational health and safety of workers. As a result of the above-mentioned possible
negative impacts on the receiving and surrounding environment, an Environmental
Management Plan (EMP) is required to eliminate and guide the operational phase of the
project. The operations of Namib Poultry (Pty) Ltd are believed to be an asset to the
residents of Windhoek and the Namibian citizens because employment will be made
available for which there is a need.
After assessing all information available on this project, Green Earth Environmental
Consultants are of the opinion that the solar plant of Namib Poultry (Pty) Ltd will not have
a large impact on the environment. The accompanying EMP will focus on mitigation
measures that will remediate or eradicate the negative or adverse impacts.
13. RECOMMENDATION
It is therefore recommended that the Ministry of Environment and Tourism through the
Environmental Commissioner support and approve the Environmental Clearance for: the
construction of a 4 Megawatt Photovoltaic Plant and Overhead Power Lines on a
Portion of Portion 7 of Farm Klein Okapuka No. 51, Khomas Region for Namib
Poultry (Pty) Ltd and to issue an Environmental Clearance for the following ‘Listed
Activities’:
ENERGY GENERATION, TRANSMISSION AND STORAGE ACTIVITIES
1. The construction of facilities for -
(a) the generation of electricity;
(b) the transmission and supply of electricity;
