1. INTRODUCTION

The BPC propose to construct a new 400 kV Overhead Transmission Line (OHTL) which will be

located between the proposed Morupule B Power Station, located near Palapye, and Phokoje

Substation, near Selebi - Phikwe. Digby Wells and Associates (DWA) were appointed as consultants

to undertake the EIA for the proposed 400 kV line as part of the MEP. The proposed MEP includes the

construction of a coal fired Power Station and the construction of a 400 kV Transmission line from

Mmamabula Power Station to Palapye and then to Selebi – Phikwe.

The 400 kV line between Morupule B and Phokoje is expected to provide a firm 400 kV supply at

Phokoje Substation. The estimated length of the line is 105km. At the Morupule Power Station, the

existing 220 kV lines from Morupule to Selebi-Phikwe and Serule are required to be deviated as part

of the scope for the 400 kV line project. The estimated length of the deviations is 5km per line. The

deviations will eliminate multiple line crossings by the new 400 kV feeders to be built at the proposed

Morupule B Power Station. The proposed line route from Morupule B will follow the route of the

existing 220 kV line between Morupule Power Station and Phokoje Substation. At Phokoje substation,

there will be a realignment of feeders and feeder bays. The new Morupule B – Phokoje 400kV line will

occupy the existing feeder bay for the Matimba – Phokoje 400kV line, including the last two towers

into Phokoje 400kV substation. The Matimba – Phokoje 400kV line will then be shifted to occupy a

vacant feeder bay which had been reserved for a future Matimba – Phokoje 400kV line which will no

longer be built. This vacant feeder bay (Matimba East) will then need to be fully equipped under this

contract. A new short section of 400kV line (approximately 1km) will also be built under this contract

for the Matimba – Phokoje 400kV line to replace the section of line occupied by the Morupule B –

Phokoje 400kV line.

The DEA approved the draft EMP for the proposed project submitted together with the MEP EIA

Report. In order for construction to commence, a project specific, detailed EMP needs to be compiled

and submitted to the DEA for approval.

2. TERMS OF REFERENCE

The Environmental Impact Statement (EIS) for the 400 kV Transmission line for the Mmamabula

Energy Project (MEP) was submitted to the Department of Environmental Affairs (DEA) for

consideration. The EIS was in accordance with Section 14 (1a) of the Environmental Impact

Assessment (EIA) Act, No. 6 of 2005, authorised by DEA on the following conditions:

• The Botswana Power Corporation (BPC) should notify Interested and Affected Parties (I&APs)

living along the Transmission line corridors and whose properties will be affected, prior to

commencement of construction work;



• The mitigation measures and impact management / monitoring recommendations that are

outlined in the EIS should be implemented totally;

• Planning permission is granted by relevant authorities before construction of the Transmission

line;

• All electrical equipment or appliances are Polychlorinated Biphenyl (PCB) free and proof to

that effect should be available during monitoring and auditing of the project.

It is, amongst others, these conditions with which this EMP seeks to ensure contractor’s compliance.

The BPC appointed PB Africa (Pty) Ltd for the Consultancy Service for the proposed Morupule B –

Phokoje 400 kV single circuit OHTL. The Environmental and Social Division of PB Africa was

responsible for the compilation of the site specific EMP. A site visit was conducted by PB Africa on 21

and 22 August 2008. The site visit included an inspection of the proposed line route between

Morupule B Power Station and Phokoje Substation.

A map indicating the location of the 400 kV Transmission line is included in Appendix A. The map

shows the line routing in relation to Morupule ‘B’ Power Station, Phokoje Substation and the

surrounding area. Furthermore, sensitive areas in terms of biodiversity are highlighted and particular

attention to biodiversity mitigation measures need to be employed along those sections of the line.

Zoomed in maps of the sensitive zones are provided in Appendix B for further guidance.

The DEA will undertake an environmental audit of the project.

3. AIM OF THIS DOCUMENT

The aim of this Environmental Management Plan (EMP) is to highlight the potential impacts

associated with the construction of the 400 kV Transmission Line and provides suitable mitigation

measures to prevent or minimise those impacts. Furthermore, it aims to incorporate the costs of

mitigation measures and rehabilitation activities into the tender budget.

The long term objectives of the EMP are:

• To ensure that, first and foremost, the RoD and regulatory requirements are adhered to;

• To ensure that necessary precautions are taken to avoid unnecessary damage or potential

future damage to the environment during the construction phase of the project;

• To ensure that all personal involved in the construction phase of the project are committed to

sound environmental best practices, as described within this EMP;

• To preserve the natural environment through all possible implementable measures where

possible.



4. GLOSSARY OF TERMS AND ABBREVIATIONS

over to provide access to and from the construction areas, and for the

transportation of the construction workforce, equipment and materials.

Route Clearing /

Blading

Clearing of a linear area with a grader. It usually implies skimming the soil

surface to remove rocks, vegetation and other obstacles likely to interfere with

the safe construction. Disturbances associated with blading (and subsequent

skimming of the soil surface) can be significantly reduced if the blade is kept

approximately five centimetres from the soil surface. By doing this, larger

obstacles will be removed but the integrity of the protective top layer of the soil

will be left intact. Gravel, pebbles and small stones on the soil surface, and small

plants will be left in place, and larger plants will be ‘pruned’ five centimetres

above ground.

5. PROJECT DESCRIPTION

5.1. Proposed Project

BPC propose to construct a new 400 kV Transmission line between the proposed Morupule B Power

Station and existing Phokoje Substation. This will involve the following activities:

• Deviations of part of the existing 220kV lines from Morupule to Selebi-Phikwe and Serule,

respectively, to prevent multiple line crossings by the new 400kV lines emanating from the new

Morupule B Power Station. This will involve the construction of new towers and stringing of

conductors and earthwires on the deviated portions of the 220kV lines;

• Dismantling of some of the existing towers on the 220 kV lines between the deviation points;

• The construction of new towers and stringing of conductors and earthwires on the new 400kV

OHTL.

The following project specific information has been incorporated into applicable sections of the EMP.

5.1.1. Construction Details

The scope of work for the construction will consist inter alia of the following activities:

• Ground line survey of the final routes selected for the overhead lines;

• Production of line profiles;

• Detailed geotechnical investigations;

• Tower plotting and optimisation;

• Design of tower foundations;

• Tower earthing design;

• Material supply to include: conductors, earthwires, composite insulators; line hardware and fittings;

vibrations dampers; arcing horns; complete towers; foundation materials; aircraft warning markers;

anti climbing devices; bird guards / diverters; etc;

• Supply of all plant and equipment for line construction;

• Site establishment;

• Bush clearing;

• Tower pegging;

• Foundation excavations;

• Tower base setting and concreting;

• Backfilling of foundations;

• Tower erection;

• Stringing; and,

• Dismantling of redundant 220 kV lines.



5.1.2. Dismantling

• Several towers along the existing 220 kV line routes between Morupule to Phokoje and Serule,

respectively, will need to be removed. This will involve the dismantling of the tower structures and

demolition, excavation and removal of the concrete foundations to 600 mm below ground level.

• The dismantling contractor will be required to dispose of all dismantled material (steel, concrete,

insulators, conductors etc.) to the appointed BPC depot. Disposal waybills will need to be

forwarded to the project consultant for confirmation.

5.1.3. Tower Construction

• Material required for each tower will be transported to the tower site and constructed on site.

• Cranes will be used to lift and place the tower structures in position. In places where cranes are

not suitable, manual means using a ginpole may be utilised for self-supporting tower positions.

5.1.4. Stringing of Conductors

• Once the towers have been erected, the conductors and earthwires will need to be strung

between each tower. In order to extend the conductors and earthwires along the route, a vehicle

will be used to drive along the servitude to pull out a pilot wire to be used for pulling the

conductors and earthwires between pulling sections, including the placement of rollers at each

suspension tower. The conductors and earthwires will then be strung by a tensioner and a puller

between stringing sections and then clamped into position at each tower site.

• Obstructions such as trees may be present on the servitude. BPC generally requires the servitude

to be cleared of all trees that may cause a flashover. The width of the strip to be cleared of trees is

not more than 40m, and will vary according to the mean height of the bush or forest and shall be

determined by ensuring that any tree after falling shall not be less than 5m clear of the maximum

deflected position of the conductor, or standing trees would not cause flashover from a conductor

deflected up to 55o from the vertical. In determining the flashover clearance and in estimating the

mean height of the bush or forest due allowance shall be made for seasonal growth. The strip of

land determined for tree clearance above shall be completely cleared of all trees, scrub and

undergrowth by felling not more than 150 mm above ground.

• No bush clearing in the form of de-stumping, scalping and uprooting is allowed on river and

stream banks. No bush clearing is allowed in or across bush filled ravines and gullies. No

protected or endangered plant species shall be removed without a PERMIT from Nature

Conservation, the landowner or BPC. The use of herbicides is strictly prohibited in Botswana



• A botanist is to be engaged before the bush clearing to identify the protected species. The

contractor to provide a botanist and will be responsible for such costs.

• Only an 8m corridor may be cleared flush with the ground to allow vehicular access. No scalping is

allowed on any part of the servitude road unless absolutely necessary.

5.1.5. Earthworks

• Cut to fill activities will be employed to ensure that excavated material (removed from the bases of

the towers during foundation excavation) is utilised for the backfilling of the holes following

construction of the tower foundation.

• Topsoil excavated from each tower position will be kept to a minimum and will be limited to the

immediate area surrounding the base of the tower. Any shortfalls required for rehabilitation /

landscaping purposes will be addressed during the landscaping contract.

5.1.6. Equipment and Materials Storage

The contractor will make use of an area to set up storage and administration area for the duration of

the contract. This will need to be located at a suitable existing site and must not be located on the

servitude.

5.2. Site Description

The following section details the findings and recommendations of specialist studies undertaken for

the MEP as well as observations during various sites visits undertaken by PB Power.

5.2.1 Existing and Surrounding Land-use

Description

The majority of the Transmission line will pass through tribal land utilised by a number of different

farmers between the towns of Palapye and Selebi – Phikwe. There are a number of cattle kraals,

posts and dwellings that exist within the servitude of the Transmission line. The line will cross over at

the point where the A1 crosses Mogapinyana Road and a railway line. The Transmission line passes

over a number of non perennial rivers in the Palapye area.

A noise and social impact assessment was conducted as part of the greater MEP. The

recommendations of these specialist reports are included as part of this project and EMP.



Implications

• Dismantling activities will generate large volumes of steel and foundation rubble waste, which will

need to be disposed of or recycled in an appropriate manner.

• The site is situated in close proximity to sensitive receptors (people, animals, etc) which may be

affected by noise and dust associated with dismantling and construction activities.

• Dismantling, construction and stringing activities are potentially dangerous to road users, residents

and the general public.

Recommendations

• Construction activities must take place during daylight hours on week days (between 07h00 and

17h00).

• Construction activities outside of daylight hours must be communicated accordingly in advance.

• There must be regular dampening of the ground to avoid dust in the working areas.

• Signage must be put in place in public places prior to any potential dangerous activities, to alert

the public of construction activities.

• Keep all equipment / machinery and vehicles in good working order and well maintained.

• Construction activities must be restricted to demarcated areas.

• All areas outside designated construction areas, shall be regarded ‘no go’ areas.

• Aircraft warning balls need to be put on the OHTL, on the span of transmission line that crosses

over the road.

5.2.2 Topography

Description

The area comprises low relief plain and featureless veld. The proposed line route crosses a number of

seasonal rivers and streamlets. The major rivers that will be crossed are the Lotsane, Dikabeya,

Tshokana and Mahunwane Rivers.

Implications

• Rivers could pose access problems during the construction and maintenance of the OHTL.

• There is the potential for erosion to occur on the banks of rivers and streams.

Recommendations

• Erosion control measures must be put in place prior to construction activities commencing.



• Minimise loss of topsoil at any one site.

5.2.3 Water Resources

Description

The servitude crosses a number of water courses between Palapye and Selebi – Phikwe. The major

rivers that will be crossed are Lotsane, Dikabeya, Tshokana and Mahunwane Rivers.

Implications

The following will be addressed in the applicable sections of the EMP:

• Stormwater emanating from access roads to the tower sites;

• Prevention of erosion and sedimentation of watercourses through the construction of berms;

• Disturbance of water courses from servitude construction;

• Sedimentation of local streams;

• Sewage and waste disposal; and,

• Hydrocarbon spillage.

Recommendations

• Plan and implement appropriate water monitoring and management plans;

• All roads need to be planned to minimise erosion;

• Chemicals and hydrocarbons capable of causing water pollution should be appropriately

transported, loaded and unloaded and stored and the necessary precautions taken when

refuelling onsite.

• Precaution must be taken when working close to such rivers in that they are not polluted with oils,

fuels and other toxic materials.

• Design and implement an appropriate waste management plan.

• Minimise construction impacts at all river crossing points through appropriate mitigation measures

where relevant.

• Avoid wet areas at any cost.

• No access roads through rivers and stream banks.

• Minimise erosion of embankments and subsequent siltation of rivers and streams.

• Warning balls need to be placed on the OHTL when it crosses rivers.

5.2.4 Geology and Soils

Description



A detailed geotechnical assessment will be conducted prior to the commencement of construction.

The major soil groups that will be crossed by the proposed Transmission routes are mostly Arenosols

and Luvisols, with small areas of Lixisols. They are mostly found on fine-grained and coarse-grained

sedimentary rocks e.g. .sandstone. Luvisols have an accumulation of clay (15-25%) and a higher

fertility, while Arenosols are coarse, sandy soils with weak structure and low fertility. In general the

soils are sandy with a low clay content (<10%); this results in high water infiltration rates, low water

holding capacity and fairly poor fertility. Lixisols are highly weathered and strongly leached soils and

they also have a zone of clay accumulation which may occur at some depth below soil surface.

Implications

• It is anticipated that excavations will be fairly easy;

• The low clay content and loose soils, has the potential to cause erosion;

• Soil compaction; and

• Soil pulverisation.

Recommendations

• Berms should be placed around stockpiled soil to prevent soil loss due to erosion.

• Roads that are frequently used should also be built up using ferricrete or calcrete that can be

obtained from an authorized local source.

• Storage and use of fuels and lubricants should be strictly confined to bunded areas. Fuels and

lubricants stored on site should be stored on an impermeable surface, such as heavy gauge

plastic sheeting. The bunded area should have a volume of 110% volume of the stored fuels and

lubricants.

• Temporary storage of fuels and lubricants may not exceed the duration of the works.

• Areas cleared of topsoil should be kept to a minimum in order to limit possible erosion problems.

5.2.5 Flora

Description

The Vegetation Map of the Republic of Botswana (1991) was used to give an indication of the general

vegetation types occurring along the proposed routes of the Transmission line. Information about

Botswana in general was also obtained from the internet (Global Terrestrial Observing Systems, 2001

& Bose, 2002).

According to White (1983), the area of concern falls within the Kalahari thornveld and the transition to

Zambezian broad-leaved woodland. This vegetation type is characterized by wooded grassland. The



area falls on the transition between the Zambezian Regional Centre of Plant Endemism (also referred

to as the Zambezian Region) and the Kalahari-Highveld Regional Transitional Zone as described by

White (1983). The area of the proposed development show strong similarities to Vegetation Type 17,

namely the Sweet Bushveld, as described by Van Rooyen & Bredenkamp (In Low and Rebelo, 1996)

and the Arid Sweet Bushveld (Veld Type 14) as described by Acocks (1988) within the adjacent

boundaries of South Africa. The Sweet Bushveld and Arid Sweet Bushveld show similarities and

correspond in vegetation composition, dominant trees, shrubs, climate and soils.

The typical vegetation in this region is savanna, containing both a tree and shrub layer and a grass

layer. Due to the extensive grazing by livestock in some areas, the relationship between these two

layers has been unbalanced, resulting in the tree and shrub layer becoming dominant over the grass

layer. This then allows the tree and shrub layer to continually out-compete the grass layer, resulting in

a dense tree and shrub layer and limited grass cover.

Because the area of interest consists predominantly of tribal grazing lands, there are no areas officially

protected, such as game reserves, for conservation value in the area of interest.

Implications

• Removal of vegetation and topsoil for servitude, towers and access roads;

• Introduction or encroachment of alien invasive species due to disturbance;

• Disturbance of animal nesting and foraging sites.

Recommendations

• Any individual plants that have Red Data Status that are found growing in an area where the

vegetation will need to be removed, must be removed by an authorised individual and should

be relocated to a safe place to avoid destruction. A nursery will be developed on site for this

purpose.

• Only the cutting of trees is permitted, no trees can be uprooted except if they fall within a

planned access or service road.

• The people involved in the construction phase should be educated on which plants have Red

Data Status so they can notify the Environmental Control Officer (ECO) should they see these

plants in vulnerable areas.

• Vegetation monitoring will include alien invasive status, should such species be encountered,

an alien invasive control programme will be developed and implemented.

• All persons involved in the construction phase should be prevented from entering areas of

vegetation that are not included as part of the project.

• All construction vehicles must be restricted to designated roads and lay down sites to prevent

unnecessary destruction of vegetation.



• Appropriate measures should be implemented to prevent erosion.

• Alien species encountered during construction activities must be removed.

• Ensure no unnecessary removal of trees or vegetation.

5.2.6 Fauna

Description

Due to the fact that the land use in this region is primarily tribal grazing land, the potential for wild

animals to occur here is very low. The identification of areas of importance that could support natural

wildlife, especially red data species, was difficult due to the fact that the majority of the land is

disturbed. The natural vegetation is disturbed due to human interference and the grazing and

browsing of domestic animals. The local people also hunt in these areas. As a result very few wild

animals were expected to occur here. The very low numbers of actual wild animal sightings confirmed

this. The wetland areas would provide watering points for the existing wildlife but due to the climate

and surface water patterns in this region these are not permanent water sources. These small

wetlands were generally located in areas utilised by humans and livestock so did not support a large

variety or abundance of wildlife. No red data mammals were observed during the site visit, no reptiles

or frogs were recorded during the specialist study investigations. There is the possibility of wild bucks,

hares and tortoises occurring in the project area. These were observed during initial site

investigations.

Implications

• Construction phase will increase local dust levels and noise levels in the area.

• The increased traffic of heavy duty vehicles and machinery will pose a threat to animals in the

area.

• The removal of vegetation during the construction phase, less food items will be available to

animals in the area and the risk of erosion will make the area even less desirable for animals

especially the browsing/grazing species.

Recommendations

• Workers should be made aware of the importance of maintaining the animal life.

• Hunting by construction workers is prohibited.

• Areas of importance, such as pans and stream banks, must be marked as no-go areas, so as to

preserve the necessary habitats.

• The destruction of the vegetative cover should be kept to a minimum, and limited to those areas

allocated for infrastructure development.



• Access gates must be installed where fences are opened for access roads and game gates must

be installed where necessary, these need to be approved by the ECO.

• Heavy vehicles should be given a strict speed limit that should be adhered to at all times in order

to minimise the potential for road related deaths.

• Minimise disruption of farming activities.

• Minimise disturbance of animals.

• Minimise breeding patterns of birds.

5.2.7 Avifauna

Description

The study area, broadly speaking can be described as arid woodland, having a grassy under storey

and a distinct woody upper storey of trees and tall shrubs. The vegetation structure is one of the most

important factors influencing bird distribution. With the vegetation zones in the study area, several

distinct bird micro-habitats are found. The current proposed alignments do not impact on the vulture

colonies in Tswanpong, as they avoid the hills completely. According to the report, the Transmission

line alignment should have no direct impacts on the birds.

Implications

• Electrocutions – Due to the large size of the clearances on most overhead lines greater than

132kV, electrocutions are generally ruled out as even the largest birds can not physically bridge

the gap between dangerous components. Transmission lines have proven to be beneficial to

many birds, by providing safe nesting and roosting sites in areas where suitable natural

alternatives are scarce.

• Collisions – Collisions are the biggest single threat posed by Transmission lines to birds in

southern Africa. Species most likely to be impacted are various water birds (wetlands and river

crossings), storks (wetlands, river crossings and agricultural lands), Secretary birds and Kori

bustard.

• Habitat Destruction - During the construction phase and the maintenance of power lines, some

habitat destruction and transformation inevitably takes place. This happens with the construction

of access roads, the clearing of servitudes. Servitudes have to be cleared of excess vegetation at

regular intervals in order to allow access to the line for maintenance, to prevent vegetation from

intruding into the legally prescribed clearance gap between the ground and the conductors. These

activities have an impact on birds breeding, foraging and roosting in or in close proximity to the

servitude through modification of habitat.

Recommendations



• Mark the earth wire of the line with anti-collision devices. There are several devices available

in southern Africa for the marking of power lines. Some are dynamic devices (usually called

bird flappers) and some are static. Dynamic devices are more effective in reducing collisions.

• Construction methods should minimise the impact on vegetation and the removal of large

trees should be avoided if the trees pose no risk of flashovers.

5.2.8 Archaeology and Historical Sites

Description

An Archaeological Impact Assessment (AIA) was conducted for the proposed transmission line and a

conditional permit awarded by the Botswana National Museum (Appendix B).

The awarded permit lists the following conditions:

• That an introduction course be performed for those involved in the construction;

• That an archaeological inspection be carried out after bush clearing;

• That monitoring is conducted during the construction of the power line, with specific reference to

those areas where archaeological remains were identified;

• That a test excavation be carried out, prior to any development, for identified sites with a

significance ranking of 2 – 3;

• Where possible, site 10 – foothill site, be preserved at all costs, and;

• That the Department of National Museum be informed of any further and/or additional

archaeological finds.



6. ENVIRONMENTAL MANAGEMENT PLAN

6.1. General Focus

This EMP outlines measures to be implemented in order to minimise adverse environmental

degradation associated with the construction of the propose Transmission power line. It serves as a

guide to the contractor and the construction workforce on their roles and responsibilities concerning

environmental management on site, and provides a framework for environmental monitoring

throughout the construction period.

6.2. Purpose

The purpose of the EMP is to:

• Encourage good management practices through planning and commitment to environmental

issues;

• Define how the management of the environment is reported and performance evaluated;

• Provide rational and practical environmental guidelines to:

Prevent pollution of land, air and water;

Protect indigenous flora and fauna;

Prevent soil erosion and facilitate revegetation;

Comply with applicable laws, regulations, standards, and guidelines for the protection

of the environment; and

Adopt the best practicable means available to prevent or minimise adverse

environmental impacts.

• Develop waste management practices based on prevention, minimisation, recycling, treatment or

disposal of wastes;

• Describe all monitoring procedures required to identify impacts on the environment; and,

• Train employees and contractors with regard to environmental obligations.



7. ENVIRONMENTAL AWARENESS AND COMPLIANCE

7.1. Introduction

The philosophy adopted in this management plan is derived from the principles of sustainable

development. Sustainable development requires that:

• The disturbance of ecosystems and loss of biological diversity are avoided, or, where they cannot

be altogether avoided, are minimised and remedied;

• Pollution and degradation of the environment are avoided, or, where they cannot be altogether

avoided, are minimised and remedied;

• That the disturbance of landscapes and sites that constitute the nation’s cultural heritage is

avoided, or where it cannot be altogether avoided, is minimised and remedied;

• That waste is avoided, or where it cannot be altogether avoided, is minimised and re-used or

recycled where possible and otherwise disposed of in a responsible manner;

• That a risk-averse and cautious approach is applied, which takes into account the limits of current

knowledge about the consequences of decisions and actions;

• Negative impacts on the environment and on people’s environmental rights be anticipated; and,

prevented and where they cannot altogether be prevented, are minimised and remedied.

7.2. Responsibilities for Environmental Management

In addition to the appointed Environmental Consultant, the DEA may need to provide input (review,

authorise, provide feedback or advice) on certain aspects of the EMP. Their prompt reaction is

required to avoid unnecessary delays during the construction period. They shall respond promptly

(within 10 working days) in writing to:

• Applications for approval of access plans and the construction campsite layout;

• Applications for approval of amendments to any EMP clauses;

• Environmentally related complaints or claims received;

• Requests to provide input on the specifications of bird mitigation devices used;

• Requests for advice on rehabilitation measures, or other environmental matter related tot eh EMP

and the project in general.

The appointed ECO will arrange for inspections of the construction activities and the EMP

implementation throughout the construction phase. The ECO will produce monthly reports (depending



on the amount of activity) that will be submitted to the client (BPC) and the DEA. Upon completion of

the project, the ECO will produce a final report, which will be submitted to the client and DEA.

The contractor and BPC or its agents shall be responsible for environmental control on site during the

construction period.

The ECO or the person/s nominated by the client must notify surrounding residents in advance of any

potentially disturbing activities.

7.3. Training and Induction of Employees

The contractor and BPC have the responsibility to ensure that all those people involved in the project

are aware of and familiar with the environmental requirements for the project (includes sub

contractors, casual labourers, etc). The EMP shall be part of the terms of reference for all contractors,

sub contractors and suppliers. All contractors, sub contractors and suppliers have to give some

assurance that they understand the EMP and that they will comply with the conditions therein. All

senior and supervisory staff members shall familiarise themselves with the full contents of the EMP.

They shall know and understand the specifications of the EMP and shall be able to assist other staff

members in matters relating to the EMP.

An environmental awareness training programme for all staff members shall be put in place by BPC.

Before commencing with any work, all staff members shall be appropriately briefed about the EMP

and relevant occupational health and safety issues.

7.4. Complaints Register and Environmental Incidents Book

The contractor must record any complaints received from the community, the complaint should be

brought to the attention of the site manager and ECO, who will respond accordingly.

The following information will be recorded:

• Time, date and nature of complaint;

• Response and investigation undertaken; and

• Actions taken and by whom.

All complaints received will be investigated and a response (even if pending further investigation)

should be given to the complainant with 7 days.



All environmental incidents occurring on the site will be recorded. The following information will be

provided:

• Time, date and nature of the incident;

• Actions taken and by whom.

The complaints register and Environmental Incidents book must remain on site / site offices at all

times.

7.5. Environmental Monitoring

An independent environmental consultant who will act as the ECO must undertake environmental

audits at a frequency that is deemed necessary by the ECO in order to ensure compliance of all

aspects of the EMP. This can be done by means of completing the EMP checklist which forms part of

the mitigation measures included in this EMP.

In order to facilitate communication between the ECO and the resident engineer and contractor, it is

vital that a suitable chain of command is structured that will ensure that the ECO’s recommendations

have the full backing of the project team before being conveyed to the contractor. In this way,

penalties as a result of non-compliance with the EMP may be justified as failure to comply with

instruction from the highest authority.

7.6. Dealing with Non-Compliance with the EMP (Penalties/Incentives for Staff)

BPC may put in place in the contractors contract, procedures to motivate the contractor and staff

members to comply with the EMP and to deal with acts of non-compliance, or deliberate malicious

damage to the environment by any staff member. It is suggested that fines / penalties be set according

to the cost required to rehabilitate the area, to the satisfaction of the ECO, should the rehabilitation be

required as a consequence of the contractor’s non-compliance with the EMP.

7.7. Roles and Responsibilities of Key Personnel during Construction Phase

In order to ensure that there is a chain of command and that key personnel are aware of their roles

and responsibilities during the construction phase of the project the following table has been

developed (to also be read in conjunction with Section 3 – Glossary of Terms).

it should be located at a previously established site in a suitable location.

Layout:

• No accommodation for construction staff (temporary or permanent) is to be

provided on site. Only security personnel will be allowed to stay on site

overnight.

• The Contractor is to adhere to the following when selecting an alternative site

for the Contractor’s Camp:

- Choose as level an area as possible (gradients must not exceed 1:3);

- Avoid locating the camp within 50m of a hydrological feature;

- Locate the Contractor’s Camp within an already disturbed area;

• The site selected must be approved by the ECO. If the ECO is not satisfied

with the proposed site, alternative sites must be proposed and discussed with

the ECO until a compromise is reached that is mutually acceptable to both

parties.

• Where possible cut to fill must be avoided during the establishment of the

Contractor’s Camp.

• The Contractor’s Camp should not exceed an area of 0.5ha.

Ensure that all site personnel have a basic level of environmental awareness

training. This training will be done by the ECO. Topics covered should include:

- What is meant by “environment”;

- Why the environment needs to be protected and conserved;

- How construction activities can impact on the environment;

- What can be done to mitigate against such impacts; and

- Awareness of emergency spills response provisions.

It is the contractors’ responsibility to provide the site foreman with no less than 1

hour’s environmental training and to ensure that the foreman has sufficient

understanding to pass this information onto the construction staff.

• Translators are to be used if necessary.

• The RE / ECO must be on hand to explain any technical issues and to answer

questions.

• Construction workers must be made aware that they are not to make

excessive noise (shouting, hooting etc.).

ECO / RE / CT

Worker Conduct on Site:

periods. CT & BPC.

8.2. Site Clearing / Earthworks / Establishment & Maintenance of Roads and Tracks


• Potential damage to the soil structure, soil compaction and loss of soil fertility.

• Loss of the vegetation cover and increased erosion risks.

• Dust related problems.

• Safety hazards to the public, workers and animals in the area.

• Disruption or destruction of archaeological remains.


• Blading takes place when a grader is used for construction earthworks, vegetation clearing,

grading platforms, cut and fill activities. The soil surface is skimmed and the vegetation cover,

including the root systems of plants, is removed.

• Tracks are created when vehicles, equipment, and even pedestrians simply move over an area.

Haphazard and off-road driving and people wandering off into the adjacent areas (especially the

river area) can easily result in the proliferation of tracks.



8.2.3 Objectives

• Carefully plan construction activities and transportation of people and equipment with the intention

to:

Avoid clearing where it is not absolutely called for;

Minimise secondary impacts such as dust and erosion; and,

Avoid compromising the safety of the public, workers and animals in the area.

Ensure that an archaeological inspection has been carried out on cleared areas.

8.2.4 Performance indicators

• Minimal erosion evident;

• No areas unnecessarily disturbed;

• No fines/penalties issued.


• Visual assessment supported by photographic records of the site.



Route and Area Clearing

Off-road driving and the creation of new tracks, other than those described

during Project Layout and Access Plan, are prohibited and will be regarded as

unwanted tracks or unwarranted disturbed areas. All unwanted tracks or

unwarranted disturbed areas shall be properly rehabilitated (see Section 8.10

and 8.11).

CT liable, Drivers,

All Staff.




• When a new path is created:

- Carefully plan the route and have it clearly marked out so that drivers

exactly know where to drive. • Establish the track by simply driving over the ground if there are no obvious

obstacles (i.e. large rocks, high plants or rough terrain).

• Keep tracks as narrow as possible and only drive on marked out routes (as

per the Layout and Access Plan).

• No bulldozers will be used in bush clearing outside of the construction

footprint. Only inflatable tyre earthmoving equipment must be used to

reduce damage to vegetation.

• If obstacles are far enough apart, divert the track around obstacles. Only

obstacles that could interfere with the safe construction and operation of the

development need to be removed.

• Where possible, remove obstacles by hand. Shrubs are to be cut or

crushed rather than being completely uprooted in areas where landscaping

will be undertaken on completion of the project

• Leave vegetation in place wherever possible, especially around the

perimeter of the site (even if they are exotic) to provide screening and

habitat. Indigenous plants can be planted to replace these exotics over

time.

• Only undertake earthworks in an area if it is unavoidable, and keep the size

of platforms (if they are necessary) as small as possible.

ECO supervise,

CT, Drivers.

• Before driving over any area:

• Rather keep to existing roads and tracks.

• Carefully examine the area to determine if there are any sensitive sites in

harms way. Clearly mark, or demarcate with plastic tape, these sites and

work around them.

Concrete Mixing:

• Concrete mixing is to take place at a site approved by the ECO. Concrete

mixing areas need to be strategically placed so as to service as large an area

as possible and compact so that the area of contamination is consolidated. Ad

hoc mixing at the active working area should be avoided where possible.

• It will be necessary to transfer the concrete from the mixing site to the active

working area. The Contractor is to propose methods of transferring the

concrete that must be approved by the ECO.

• If small volumes of concrete are to be mixed (manually), mixing is to be

undertaken on a hard surface covered in plastic sheeting so that concrete

waste and runoff can be contained.

• If large volumes are generated the following requirements must be met:

- Mixing area must be underlain by an impermeable surface that is

sufficiently large to trap spills;

- Runoff from the concrete mixing area is to be contained and channelled into

a wastewater sump.

• All concrete waste is to be collected and removed from the site for disposal at

an appropriate disposal site.

RE / ECO / CT




Contaminated Water and Soils

• All soil that is contaminated must be removed and stored in a skip until it can

be disposed of at an appropriate disposal site.

• All wastewater and polluted runoff from contaminated areas must be

channelled into appropriately sized, designed and located collection sumps.

• The size, design and location of the polluted runoff capture system must be

assessed and approved by the ECO.

include, but are not limited to:

- Demolition of concrete foundations and

existing buildings;

- Grading / movement of soil;

- Transportation and unloading of

construction materials;

- Vehicular movement over unsurfaced roads

Managing Surface Water

Discuss water provision for construction purposes. CT and BPC

Do not drive any vehicle through any watercourse or water body. CT, BPC and

drivers.

• Do not impede or deviate the flow of any surface water body.

• Do not dispose of any waste into surface water bodies.

• Adequate bunding must be designed around the business park to prevent

any spillages contaminating the ground/surface water system.

• Do not use any surface water bodies for domestic purposes including

bathing, washing and drinking water.

CT and BPC, ECO

supervise

• The Contractor may not cause the pollution of any watercourses, whether

flowing or not, along the OHTL route.

• To control and minimise the washing of soil into watercourses, the

Contractor must implement the following:

- Appropriate soil management strategies;

- Prompt rehabilitation to protect and stabilise exposed soil surfaces.

- Follow the requirements for soil stockpiling and management.

• To prevent the contamination of water by materials used during construction,

the Contractor must ensure the following:

- Materials are prepared and stored away from watercourses;

- Measures must be implemented to prevent seepage of liquid materials

into the ground where it could contaminate groundwater;

- Ensure prompt cleaning up of accidental spillages

• To prevent the contamination of watercourses by diesel, grease, oil, etc.

derived from the camp and working area, the Contractor must ensure that:

- The machinery / equipment is maintained in a good operating condition;

- Specially designated areas for vehicle maintenance are created;

- Accidental spillages are cleaned up promptly.

- No servicing of vehicles / machinery / equipment in the field.

• No water is to be abstracted from any watercourses for use during the

construction phase unless approved by the ECO, provided that an

appropriate licence is obtained.

• No members of the construction team will be permitted to use any

watercourses or water bodies for domestic purposes such as washing or

bathing.

• The watercourses and water bodies are not to be used for the rinsing and

cleaning of construction equipment. This is to be done at the Contractor’s

Camp in an appropriate work area.

RE / CT / ECO




Soil Management / Topsoil / Dust Control

• Implement measures to prevent dust from becoming problematic. These

measures shall include, but are not limited to:

- Restricting excessive vehicular movement.

• Limit vehicle speeds on un-surfaced roads and tracks to 30km/h along dust

roads and 20km/h along the steep or difficult tracks.

• During periods of prolonged use, un-surfaced roads must be dampened if

dust becomes a problem.

• Disturb as small an area as possible.

• Vehicles will be kept to a single path, and soils ripped and replanted with

indigenous species upon completion of all construction phases.

• All construction activity near the rivers will be kept to a minimum, and

erosion prevention mechanisms must be employed before the

commencement of construction.

CT and BPC, ECO

supervise.

Soil Stripping:

For the purposes of this report, topsoil is considered to be the top 200mm of

soil:

• All topsoil is to be stripped at the tower sites to a minimum depth of 200mm.

Where there is less than 200mm of soil, the maximum available topsoil must

be stripped.

• At tower sites, topsoil will need to be stripped by hand (either with or without

sods). The soil may be stripped mechanically at sites approved by the ECO.

RE / ECO

Soil Handling:

• Soil must not be handled when it is wet as this will result in unnecessary

compaction; however this needs to be balanced against the high erosion

potential of soils when they are dry.

• Repeated handling of soil must be avoided, as it results in compaction and

the loss of soil structure. Planning the soil stripping and stockpiling process

and allocating formal stockpile areas will minimise the chance of repeated

handling.

• If the soil stockpiles are to remain unused for more than two months they will

need to be vegetated with a suitable grass / legume mix.

• Soil must not be handled during windy conditions to minimise soil loss

through wind erosion.

• In order to minimise the risk of spillage and loss through wind erosion, trucks

transporting soil must not be overloaded when conveying soil to, from and

around the site.

• Soils being transported long distances must be covered with a tarpaulin.

RE / CT / ECO




Soil Stockpiling and Management:

General Guidelines

• All stripped soil (topsoil and subsoil) is to be stockpiled so that it can be used

in the rehabilitation process.

• Soil that is to be stockpiled for an extended period must be stored:

- At a sheltered site where it will not be exposed to the effects of wind

erosion;

- Outside the working area where it will not be disturbed or contaminated;

- Away from drainage lines so as to avoid the risk of erosion;

- Away from areas of valuable indigenous vegetation.

• Topsoil (top 200 mm) is not to be mixed with subsoil.

• Soil is not to be stockpiled against tree trunks, as this will encourage ant

infestations.

• Topsoil is not to be used as a bedding material.

Location of Soil Stockpiles

• Stockpiles must not be situated such that they obstruct natural waterways

and drainage lines.

• Soil stripped from the tower sites will be placed upslope of the excavated

hole (if possible) to prevent erosion.

• Topsoil and subsoil stockpiles will need to be contained to prevent mixing.

• The stockpiling period is not to exceed 3 weeks.

• Soil is to be stockpiled in small manageable piles not exceeding 2 m in

height.

Stockpile Maintenance

• Stockpiles are to be protected from wind and water erosion:

• Short-term stockpiling (less than 3 weeks) erosion control measures will

not need to be implemented; however, limitations on the area to be cleared

will apply.

• Medium-term stockpiling (more than 3 weeks), stockpiles must be covered

with biomatting.

• Long-term stockpiling (more than 2 months), stockpiles must be

revegetated by hydroseeding or sowing with an appropriate grass / legume

mix.

• The colonisation of stockpiles by invasive plants must be controlled by

removing the plants when they germinate. The purpose of this is to reduce

the risk of developing a seedbank of invasive species within the stockpiled

soil.

With regards to sensitive sites strictly enforce the following mitigation

measures:

• Get to know which sites are sensitive and mark or demarcate these with

plastic tape to increase their visibility, thus helping to prevent accidental

destruction and avoid unnecessary damage.

• Prevent people from going to, or driving over, these areas.

• Where they cannot be avoided altogether, minimise impacts by removing as

little vegetation as possible.

• Avoid clearing of sensitive areas. Remove vegetation by hand. Feather-back

the vegetation and avoid removal of large tracts of vegetation.

Identify areas identified as ‘sensitive sites’ on the Project Layout Plan for

comment and review by DEA. ECO and PB

• The following must be done to ensure the protection of the vegetation:

- Indigenous trees along the OHTL route are to be protected and painted

with ‘anti-muthi’ paint (e.g. brown coloured PVA).

- Steps must be taken to ensure that the poaching of fauna or removal of

flora does not occur, and the following steps must be implemented:

- All staff members are required to attend the environmental awareness

meeting;

- Employees will be subject to fines, should they be caught poaching fauna

or removing flora from the site or immediate surrounds.

- No member of the construction team may harvest, damage or remove

plants, especially those in designated ‘out of bounds’ areas.

- Confine the disturbance to a narrow, clearly defined corridor.

- Use only plant species endemic to the site for rehabilitation purposes in

order to recreate animal habitats, as they were pre-construction (using

other species will alter the habitat, especially for birds, and render it

unsuitable).

- Revegetate the disturbed area as quickly as possible.

- The Client is to ensure that follow-up work / monitoring is scheduled over

a suitable time period (at least six months) to ensure that the planted

vegetation establishes itself, that the natural re-colonisation by

indigenous, pioneer plants is successful and that alien plants are

controlled.

- Before construction proceeds in any section, the ECO is to assess the

proposed OHTL route to determine the presence of nesting or refuge

sites. Should any such sites be found, an appropriately qualified person

is to be appointed to determine the best course of action.

sensitised to the fact that these toilets shall be used at all times during the

construction period

CT

Communication with Interested and Affected Parties (I&AP’s):

• The RE and Contractor are responsible for ongoing communication with

those people that are interested in or affected by the project.

• A complaints register is to be housed at the site office. This must be in

carbon copy format, with numbered pages. The Contractor must account

for any missing pages. This register is to be tabled during monthly site

meetings.

• I&AP’s need to be made aware of the existence of the complaints register

and the methods of communication available to them.



• Queries and complaints are to be handled by:

- Documenting details of such communications;

- Submitting these for inclusion into the complaints register;

- Bringing issues to the immediate attention of the RE; and

- Taking remedial action as per the RE and / or ECO’s instructions.

• Selected staff are to be made available for formal consultation with I&AP’s

in order to:

- Explain the construction process; and

- To answer any questions.

RE / ECO

8.9. Rehabilitation

8.10.1 Potential Impacts and Impact Sources

• Permanent scarring of the landscape if tracks or disturbed areas are not repaired, and if the

construction campsite is not properly reinstated.

• Inadequate rehabilitation due to insufficient budget allocations.

• Destruction of indigenous vegetation by the colonisation of alien exotic species.

8.10.2 Objectives

• Make sure there are sufficient budget allocations for environmental rehabilitation.

• Rehabilitate unwanted tracks or unwarranted disturbed areas as best as possible.

• Remove potential ‘eyesores’ and leave the construction campsite and entire construction area in a

neat and safe condition (before final hand-over of the site).

8.10.3 Principle

• Rehabilitation will be done as soon as possible after completion of construction activities in any

one area.


• Adequate soil available for rehabilitation;

• The increase in occurrence, density and diversity of exotic by indigenous species;

• A reduction in the incidence and spread of alien invasive species;

• Leaving of a clean and tidy site at the end of construction.




• Inspection of all rehabilitated areas.



Tender Process

This EMP is to form part of the tender document. BPC

With the awarding of the tender, the Contractor is to be informed of any

intention to impose fines/penalties for transgressions to the contents of this

EMP so that the Contractor is able to assess the impact that the associated

restrictions might have on his normal way of working and justify additional costs,

where necessary.

BPC & CT.

The Contractor may not be geared up to carry out some of the rehabilitation

activities which are specified during the construction phase, i.e. spreading of

stockpiled topsoil, the replanting of vegetation, seeding, watering and invasive

plant control. These activities will have to be done by a firm of specialists,

ideally appointed and managed by an independent consultant. Nevertheless,

there must be sufficient budget allocations for environmental compliance.

The following list is presented as a sample of potential cost items. It is not

exhaustive.

• Staff training;

• Stormwater control facilities;

• Alien plant control;

• Relocation of plants;

• Working around sensitive areas;

• Revegetation;

• Pollution control facilities;

• Waste control and recycling;

• Dust suppression;

• Use of ‘environmental friendly’ chemicals/cleaning products;

• General Housekeeping;

• Undertake noisy activities during the day;

• Demarcation of the working area; and

• Restriction of speed of vehicles on unsurfaced roads

BPC, CT, ECO and

DEA

Throughout the Construction Phase




In consultation with the ECO, identify all areas requiring rehabilitation, including

unwanted tracks, unwarranted disturbed areas and areas of excessive alien

invasive plant infestation and develop the best practical rehabilitation measures

for the specific areas in question. Measures include, but are not limited to:

• Hand-raking the ground in sandy areas to remove tracks or scars.

• Ripping of compacted soils and breaking up the clods to ensure proper

drainage and water infiltration.

• Tilling the topsoil layer to establish a smooth surface.

• Sweeping or dragging a heavy cloth over an area.

• Scattering pebbles and rocks over an area to make it blend in with the

surroundings.

Rehab. CT and

BPC, ECO advise.

• Topsoil (containing the valuable seedbed) that has been stockpiled for

excavation of tower foundations will be spread over the subsoil and bedrock

in areas requiring rehabilitation for the facilitation of vegetation

establishment.

• Where compaction by vehicular or construction activity has occurred, soils

will be ripped immediately following completion of construction and

rehabilitated by planting, hydroseeding, or both.

• Vegetation will also be planted in clumps in order to resemble the natural

vegetation as much as possible.

Rehab. CT, ECO to

advise.

• Water the revegetated areas thoroughly after seeding/planting and for the

first dry season, in particular.

• Ensure that when final rehabilitation is complete, all invasive plants have

been removed and destroyed.

• Appoint a responsible community member (who is familiar with the

procedures) to continue with the invasive plant control programme.

• Instigate an alien replacement programme on the site (and monitor).

Rehab. CT, ECO to

advise.

• Inform and educate residents and contract staff as to the correct procedures

for encouraging the growth of indigenous vegetation, the removal of exotic

vegetation and the prevention of its spread.

• Monitor the success of rehabilitation measures and revise the measures if

they were proved to be unsuccessful.

Rehab. CT, ECO,

DEA to advise.

Before Closure




• Remove all construction equipment, surplus materials and temporary

structures, fences and works of every kind.

• Clear windblown litter and other waste from surrounding areas.

• Remove all remaining waste to a recognised dump

• Repair damage to roads, fence lines, telephone lines, etc. caused by

construction.

• Ensure there are no bare areas. Platforms must be grassed if they are not

to be developed immediately.

All CTs and BPC.

8.10. Post Construction Activities

Site rehabilitation is an essential component of this EMP and must be carried out in conjunction with

the ECO. The guideline is to be used as the basic structure for the site rehabilitation; the specific

details must be decided by the Rehabilitation Contractor in conjunction with the ECO. This applies

most specifically to the soil replacement, amelioration and revegetation components.

• The requirements for the control of soil, water, dust and noise pollution stipulated in this EMP still

apply during the site rehabilitation phase of the project.

• Similarly, the requirements for soil management, erosion control, alien vegetation removal and

vegetation and fauna protection also apply.

• Livestock must be kept away from the rehabilitated areas for a sufficient period to allow the plants

to become sufficiently well established before being exposed to trampling or grazing.

Activity Monitor

Rehabilitation

Infrastructure

• Disassemble all infrastructure units and remove components from the working

areas and Contractors Camp. This will include storage structures and

containers, water storage containers, power supply, etc.

• Drain all portable chemical toilets, being careful not to spill the contents.

Transfer the contents to an appropriate disposal site.

• Drain all wastewater and sewage associated with the temporary ablution

facilities and transfer the waste to an appropriate disposal site.

• Disassemble all fencing around the camp and either sell, auction or donate

the components to the local community or transfer the waste components to a

disposal site or the Contractors base.

• Do not leave any components, waste or infrastructure units within the working

area and camp unless specifically required for the operational and

RE / ECO



maintenance phases and as agreed by the ECO.

Contaminated Substrates and Pollution Control Structures

• Excavate all areas of contaminated substrate, transfer the contaminated

substrate to an appropriate disposal site and treat the affected areas with

appropriate ameliorants.

• Remove all plastic linings used for pollution control and transfer to an

appropriate disposal site.

• Break up all concrete structures that have been created (e.g. working and

parking surfaces) and remove concrete waste to an appropriate disposal site.

RE / ECO

Waste

• Remove all remaining construction materials from the camp and working

areas and either sell, auction, donate to the local community or transfer to the

Contractor’s base.

• Remove all construction debris, litter and domestic waste from the camp and

working areas and transfer to an appropriate disposal site. Remove all waste

receptacles from the camp and working area either donate to the local

community, auction, or transfer to Contractor’s base.

• Do not burn or bury any waste at the Contractors Camp or in the working area

– all waste is to be transferred to a permitted disposal site.

RE

Collection Sumps

• Drain all collection sumps and dispose of the contaminated liquid and solids at

an appropriate disposal site.

• Remove the tanks or plastic linings or similar and transfer to a permitted site

for disposal.

RE / ECO

Access Routes

• For those roads that are to remain in place, the Contractor is to ensure that

the parallel and side drains are in a satisfactory condition on completion of the

construction phase and that the roads are rehabilitated to their former state.

• For those roads and other hardened surfaces that are to be decommissioned

the following is required:

- Rip the compacted surface using a disc harrow or mechanical plough;

- Fill any cuts with spoil and subsoil (where applicable);

- Replace topsoil;

- Peg biomatting onto those areas where backfilled / capped surfaces are

steep (Identified by ECO);

- Plant or seed with a suitable rehabilitation plant species mix.

RE / ECO

Revegetation

• It is important that the revegetation activities be planned in advance to ensure

that seed and plant stockists are able to supply the required volume when



required.

• All revegetated areas will need to be watered to ensure plant growth and

development. The volume and frequency of watering will be left to the

discretion of the Rehabilitation Contractor and ECO.

• All areas within the camp or along / adjacent to the OHTL route, where soil

has been stripped, disturbed and replaced will need to be revegetated.

• This may include:

- Contractor’s Camp;

- Additional infrastructure;

- Access routes;

- Other area disturbed during the construction phase.

CT / RE / ECO



9. CONCLUSION

Due to the power line servitude traversing agricultural land, grazing land and several drainage lines,

the dismantling and construction of towers and associated stringing of conductors has the potential to

cause significant impacts on both the biophysical and socio-economic environment in the area. If the

above-mentioned management recommendations are adopted, however, it is anticipated that most of

the negative environmental impacts of dismantling and construction can be prevented or at least

minimised. An appointed Environmental Control Officer (ECO) will monitor the site throughout

construction to ensure that the required environmental controls are in place and are functioning

effectively.
