1.1 GENERAL PROJECT DESCRIPTION The proposed project (Tombo-Mafini) entails the construction of approximately 16.5 km of Chickadee 132 kV power line on guyed steel monopole structures. The proposed power line takes off from the Dumasi-Zimbane 132 kV power line, approximately 2 km east of the village of Cibeni and extends to the proposed Tombo substation near the village of Tombo. The proposed Tombo-Mafini power line joins up with the previously authorised Dumasi-Tombo 132 kV powerline and follows the same lineation for approximately 2 km where it joins up to the Tombo substation. The Tombo substation and Dumasi-Tombo powerline formed part of an EIA undertaken in 2010, of which received Environmental Authorisation on the 20th of September, 2010 (authorisation register number 12/12/20/1493; attached in Annexure G). The new Tombo-Mafini 132 kV overhead power line is required to strengthen the electricity grid supply to the northern areas of the Port St Johns Local Municipality and the North-eastern areas of the Nyandeni Local Municipality within OR Tambo District Municipality, Eastern Cape. The proposed project will involve the construction of:

• 16.5 km of 132 kV overhead Chickadee power line

• 65 guyed steel monopole structures. The study area is predominantly located within the Port St Johns Local Municipality, with a small portion of the line (near the take-off point) falling within the Nyandeni Local Municipality. The study area fall outside the urban edge within either the River Valley Zone or High Lying Hinterland development zones, as identified in the Port St Johns Local Municipality Spatial Development Framework. Motivation to improve network:

• Provides capacity for existing and future developments in the area

• Improves reliability of supply

• Increased revenue

• De-loads existing substations which will help to maintain firmness within the study area.

The Spatial Development Framework of the Port St Johns Local Municipality identifies Tombo as having the potential to develop into the second largest nodal point within the municipal area. Tombo currently serves an important administrative node to the surrounding rural communities since it provides, amongst others, a post office, clinic, government offices, an art centre, community hall and training centre. The proposed Tombo-Mafini powerline would therefore assist in facilitating the objectives of the Port St John Local Municipality Spatial Development Framework.

Need and Desirability of the Project The reliable provision of electricity by Eskom is critical for industrial development and related employment and sustainable development in South Africa. As electricity cannot be stored, power is generated and delivered over long distances at the very instant that it is required. In South Africa, thousands of kilometres of high voltage Transmission lines (i.e. 765 kV, 400 kV and 275 kV Transmission lines) transmit this power, which is predominantly generated at the power stations located outside the Eastern Cape Province, to Eskom’s major substations. At these major substations, the voltage is down-rated and distributed to smaller substations all over the country via distribution lines (e.g. 132 kV, 88 kV and 66 kV power lines). Here the voltage is down-rated further for distribution to industry, businesses, farms and homes. In order to maintain a reliable power supply within the entire network, the voltages at all substations are required to be within certain desired limits. If the network is operated at voltages which are below these limits, voltage collapse problems and power outages may be experienced which will in turn adversely impact on the economic growth potential of the area. Environmental Authorisation This report represents the Basic Assessment Report (BAR) and has been prepared in accordance with the EIA Regulations published in Government Notice No. R543. These regulations fall under Section 24(5) read with Section 44 of the National Environmental Management Act, 1998 (Act No. 107 of 1998 as amended in 2010) (NEMA).

The NEMA Section 24(5) stipulates that “listed activities” require environmental authorization by way of a Basic Assessment or full Environmental Impact Assessment. The Background Information Document initially only identified one listed activity as being relevant to this project, however further assessment has identified a number of additional activities of which are activated by the proposed development. The proposed activity is listed under Government Notice R544 and Government Notice R546, promulgated in terms of the National Environmental Management Act, Act 107 of 1998 (NEMA), amended in 2010, as:

1.2 DESCRIPTION OF PROPOSED ACTIVITY Location and site description of the proposed development The study area is located approximately 70 km to the southeast of Mthatha and falls within the Port St Johns Local Municipality and Nyandeni Local Municipality. The take-off point will be from the existing Dumasi-Zimbane 132 kV power line at a point within the Nyandeni Local Municipality. The new Tombo-Mafini 132 kV powerline will travel in a south-easterly direction where it links up with a previously authorised Dumasi-Tombo powerline where it travel for approximately 2 km to the Tombo substation, located adjacent to the road that feeds Mpande and is near the R61 road intersection some 20 km from Port St Johns on the R61 to Mthatha. The Dumasi-Tombo power line and Tombo substation formed part of an EIA undertaken in 2010, of which received Environmental Authorisation on the 20th of September, 2010 (authorisation register number 12/12/20/1493).

Figure 1: Locality map indicating the location of t he preffered alternative (indicated with blue) and minor alternative (indicated with black). Construction Phase The actual construction activities associated with the power line follow: 1. Building of foundations for the towers 2. Tower assembly and erection 3. Conductor stringing 4. Final inspection of the line and taking over from contractor 5. Rehabilitation of disturbed areas. The foundations are constructed first, followed by the assembly of the towers on the ground, then the erection of the towers and finally the stringing and regulation of the conductors. a) Construction of ~16.5 km of 132 kV overhead line from the existing Zimbane-Dumasi

132 kV power line to the proposed Tombo substation

For proposed overhead power lines, an area with a strip width of 6 m will be cleared along the entire route. Holes will then be drilled for each supporting pole or blasting may be employed. Small amounts of concrete will be mixed for the site stabilizing towers (~ 0.5 cubes per strain tower / 1 every 1.5 km). The internal towers will generally be placed on pre-cast foundations (~ 0.5 x 0.5 x 0.5 m). b) Construction of access roads Minor vehicle access roads may be created during the construction phase where these are not already available.

Earthmoving equipment may be required to establish access roads. All areas that will be disturbed such as construction camps, access roads and the construction area around the towers will have the topsoil stripped and stockpiled for use during the rehabilitation phase. Eskom estimates that it takes approximately 1 month for every 12 km. The construction for this project should thus be completed after approximately 2 months.

Operational Phase: 1. Maintenance of Infrastructure The 132 kV power line will require routine maintenance work using access roads. Existing roads will be used as far as possible to avoid constructing new roads. 2. Corrosion Corrosion of structures is frequently found where the protective system, either galvanizing or a protective organic coating, has weathered, exposing the steel substrate. With routine maintenance, this form of corrosion can be avoided. 1.3 SURROUNDING LAND USE The land use of the areas of which the proposed power line transverse is restricted largely to rural villages and subsistence farming including low intensity subsistence livestock grazing and food plots. The area consists mainly of un-alienated state-owned land under the jurisdiction of the Department of Land Affairs. Land tenure is primarily communal, with chiefs and headmen responsible for the allocation of land-use rights. The Majola Tea Estate, one of the largest tea plantations in South Africa, can be found approximately 3.5 km to the east of the new power line take-off point. Majola is an interesting example of agricultural black empowerment in as much that its workers own the estate. 1.4 DESCRIPTION OF THE ENVIRONMENT Local Economy Port St Johns is a small coastal town in South Africa that owes most of its revenue to tourism. It is the hub of the Eastern Cape. The economy is largely subsistence-based. Most families live off social grants and pensions, as job-seekers tend to leave the rural areas and migrate to the larger cities such as Durban, East London and Johannesburg where there are more employment opportunities. Port St Johns offers a unique blend of cultural richness, as the Xhosa culture; both modern and traditional is always present. Many of the local population rely on tourism as an opportunity to make an income, selling curios and other memorabilia, as well as providing tours and other initiatives to offer tourists a taste of local culture. Port St Johns also provides an overnight rest place for those travelling through the area, a place where businessmen can stay when working in the area, as well as a beautiful holiday destination. The Port St Johns area lays claim to the Majola Tea Estate, which is a 450 ha tea plantation, situated on the rolling hills of Port St Johns and owned by its workers. The tea plantation provides the people of


10

this area a means of generating an income by means of international trade.

Demographics Statistics from the 2001 Census indicate that the Port St Johns Local Municipality, in which the study area lies, has a total population of 146 967. The number of households is said to be in the order of 28 869 and is divided into 13 Wards. Port St Johns Municipality constitutes approximately 8.7% of the total population of O.R. Tambo District Municipality (ORTDM). Households contain average family sizes of six people. The majority of the population are below 30 years old and, due to the migrant labour system, women head the majority of households. Unemployment levels are high. The lack of energy resources within rural areas of South Africa is recognised as a major factor retarding socio-economic development. According to StatsSA Census 2001, less than half of the population in the Eastern Cape have electricity for lighting purposes, while 28% and 24% of the Eastern Cape population utilise electricity for cooking and heating respectively. It is made evident from the above information that network strengthening in terms of electricity distribution in the Eastern Cape is greatly needed. Climate The Port St Johns area is characterised by a sub-tropical climate with rainfall occurring mainly in the summer months. The area has a comparatively high rainfall, with the coastal and mountain regions receiving over 1000 mm per annum. Rainfall occurs all year round with summer peaks (October to April). In the winter months, snow has been known to occur in the high altitude regions. Extreme wind events have been recorded in Transkei, and could impact negatively on power lines. Geology and Soils Sandstones of the Beaufort Group of the Karoo Supergroup dominate the area of Port St Johns. The northern coastal region is located on the Horst of the Table Mountain Group around which sediments of the younger Ecca Group are deposited. The area is characterised by fairly resistant sandstones, which form the prominent topography. The coastline of Port St Johns comprises mostly of Ecca and Dwyka sediments with many intrusions therein. The route of the proposed 132kV powerline is underlain by Ecca Group sandstones and mudstones, dolerite intrusions and recent alluvium. According to the Palaeontological Impact Assessment undertaken by Rob Gess Consulting, the Ecca Group strata are potentially palaeontological sensitive. The Ecca Group sediments transverse by the powerline include corse and finer grained sediments, both of which contained only fragmented plant material. The palaeontologist has therefore indicated that it would e extremely unlikely that significant palaeotological material will be disturbed during the development of the proposed powerlines. Soils are generally highly erodible and, with the poor veld management and mismanagement of riparian areas, erosion dongas and gullies may develop. Heritage This section is dealt with in more detail in section 6 of this report. In conclusion the Cultural Heritage Specialists have recommended that the development proceed with the following heritage mitigation:

−−−− That tower placements should be negotiated with residents to ensure that no ancestral graves

are affected.


11

−−−− Any observed archaeological remains should be reported as per SAHRA protocol.

Vegetation Three main vegetation types, namely the Ngongoni Veld, Eastern Valley Bushveld and the Southern Mistbelt Forest, dominate the study area and all three are classified as being Least Threatened or Vulnerable. The Eastern Valley Bushveld characterises the flanks of most rivers, where Acacias and Euphorbias dominate. The Ngongoni Veld borders the coastal strip. The Eastern Valley Bushveld is dominated by species such as: Coastal Buffalo grass (Stenotaphrum secundatum), Ngongoni or Wire grass (Aristida junciformis), and Giant Turpentine grass (Cymbopogon validis), Bitter Aloe (Aloe ferox), Sweet Thorn (Acacia karoo), and the common Umzimbeet (Millettia grandis). Most of the forests in the study area are demarcated as “State Forests” and are protected for the benefit of the local inhabitants. Typical trees of the forest biome include Giant Umzimbeet (Millettia sutherlandii), Forest Mahogany (Trichilia dregeana), Forest Ironplum (Drypetes gerrandii), Forest Fever Berry (Croton sylvaticus), Forest Bushwillow (Combretum krausii), and Small-leaved Jackal-berry (Disopyros natalensis). Rare and threatened trees found in the forests are Transvaal Stinkwood (Ocotea kenyensis), Forest Potato Bush (Phyllanthus macnaughtonii), and Forest Canary-berry (Suregada procera) (www.portstjohns.org.za). The proposed power line falls within both a terrestrial CBA 1 and CBA 2 area (refer to Figure 2). The construction of the power line will require mitigation measures to ensure the impact on vegetation is kept at a minimum.

Figure 2: Terrestrial CBA areas The proposed power line falls within an aquatic CBA 1 area. Construction within the aquatic environments, such as within river valleys must be undertaken such that the impacts on these areas are kept to a minimum.

The study area is located approximately 70 km to the southeast of Mthatha and falls within the Port St Johns Local Municipality and Nyandeni Local Municipality. Two route alignment options are being considered, a preferred route and a minor deviated route. Both options take off from the existing Dumasi-Zimbane 132 kV power line at a point within the Nyandeni Local Municipality. The preferred option, indicated in blue in Figures 2 and 3, will travel in a south-easterly direction over the Mngazi River where it links up with the previously authorised Dumasi-Tombo 132 kV power line and follows the same lineation for approximately 2 km where it links up with the Tombo substation, located adjacent to the road that feeds Mpande and is near the R61 road intersection some 20 km from Port St Johns on the R61 to Mthatha. The minor alternative, indicated in black in Figures 2 and 3, follows the same route as the preferred alternative but deviates in an easterly direction approximately 1.1 km north of the Mngazi River. The minor alternative travels for approximately 3.5 km where it crosses the Mngazi River and again joins the preferred alternative route. In both cases the surrounding vegetation have been heavily impacts from surrounding agricultural activities including extensive overgrazing. The proposed works all fall within un-alienated state land. Wayleave are entered into between ESKOM and the relevant tribal authority regarding access to land for servitudes. The department of Land Affairs compensates communities financially where relevant. The Department of Land Affairs (DLA), through a community resolution process will undertake the site transfer process, should an Environmental Authorisation (EA) be issued. The community leaders have signed a letter of no objection to the project proposal (Refer to Appendix G) (b) the type of activity to be undertaken;

ESKOM are proposing to construct approximately 16.5km of new 132kV overhead powerline (Tombo-Mafini) taking off from the existing Dumasi-Zimbane 132kV powerline to the Tombo substation.

Pylo n Alternatives No. Alternative type , either

alternative: site on property, properties, activity, design,

technology, operational or other (provide details of “other”)

Description

1. Technology Alternative (Monopole structure)

• Monopoles are single structures used to minimize impact on land use, wildlife and scenic views.

• The multitude of elbows and joints of lattice structures make ideal raptor perches which, in tandem with wide, clear-cut rights-of-way, create measurable negative impacts on wildlife.

• Some monopoles are single, self-supporting, vertical poles with no guy wire anchors. They can be as tall as lattice towers, but their single stem makes them less obtrusive, and they require only an eight-foot base.

• Monopoles offer aesthetic benefits and definitely require a smaller servitude for adequate placement. The monopole designs include rounded edges, which eliminates raptor perches and protects them


14

from accidental electrocution.

In terms of design, various support towers or “pylons” were considered. These included a 5-pole wooden tower, concrete monopole tower or a steel monopole tower. The 5-pole wooden tower is no longer considered feasible due to the excessive maintenance requirements where poles require regular replacement. The two feasible alternatives are therefore concrete monopole towers or steel monopole towers with guides.

Figure 5: Alternative Towers to be considered (Concrete Monopole (left) and a Steel Monopole with Guides (Right).

2. Technology Alternative (Lattice structure)

• Lattice structures mostly four-legged structures.

• Lattice structures require guy wire anchors for support. They are also tall and obtrusive.

• The pylon design will be in accordance with the OHS Act which stipulates the clearance levels to ground, road, building etc., and also by taking into account the local area in terms of birds and animals.

(d) the technology to be used in the activity;

Monopole and lattice structures have been considered. However due to the maintenance requirements, negative impacts on wildlife, vegetation clearing requirements and visual impacts associated with lattice structures, monopole structures are preferred. Due to the high weights associated with the concrete monopole structures, it is likely that steel monopoles will be utilised for the proposed powerline construction.

(e) the operational aspects of the activity; and

There are no feasible or reasonable alternatives.


15

(f) the option of not implementing the activity.

No-Go Alternative Due to the planned growth in the Port St Johns area an upgrade of the existing ESKOM distribution infrastructure is required. The new 132kV overhead powerline is therefore required to strengthen the grid supply in the Eastern Cape in response to planned growth. In terms of providing stable electricity supply in the Port St Johns area, the no-go alternative is not a practical or feasible project alternative. By not increasing the supply to the greater area, development will be constrained as the existing networks are at capacity. New electricity connections will not be viable and households will continue using alternative sources of energy for cooking, heating and lighting. These sources are mostly from non-renewable sources of electricity such as paraffin, gas, candles and fire-wood. Such forms of energy deplete fertile sources of fossil fuels. In addition, many are considered unsafe (e.g. paraffin and wood fires) and create safety risks to communities. Economic benefits related to the development, include job opportunities during construction and operation, contribution to infrastructure and development of the area. The no-go alternative will therefore have a direct impact on the provision of electricity and development in the area. The No-Go alternative may prevent the occurrence of negative environmental impacts such as construction associated risks (fires, spills of hazardous materials), impacts on ground and surface water quality with particular respect to Mngazi River; impacts on air quality and noise generation during construction; potential soil erosion from earthworks. Describe alternatives that are considered in this application. Alternatives should include a consideration of all possible means by which the purpose and need of the proposed activity could be accomplished in the specific instance taking account of the interest of the applicant in the activity. The no-go alternative must in all cases be included in the assessment phase as the baseline against which the impacts of the other alternatives are assessed. The determination of whether site or activity (including different processes etc.) or both is appropriate needs to be informed by the specific circumstances of the activity and its environment. After receipt of this report the competent authority may also request the applicant to assess additional alternatives that could possibly accomplish the purpose and need of the proposed activity if it is clear that realistic alternatives have not been considered to a reasonable extent. Paragraphs 3 – 13 below should be completed for each alternative.

�� YES NO

If yes, what estimated quantity will be produced per month? Unknown

How will the construction solid waste be disposed of (describe)?

Waste that will be produced on site include plastic bags and other domestic waste that the contractors may bring on site. This waste should be collected weekly and disposed of in a safe manner at the landfill utilised by the Local Municipality.- The management of this waste is to be addressed in the Environmental Management Programme (EMP).

Where will the construction solid waste be disposed of (describe)?

Construction solid waste and general waste produced during construction will be disposed at a landfill as utilised by the Local Municipality.

Will the activity produce solid waste during its operational phase? YES �� NO

If yes, what estimated quantity will be produced per month? N/A

How will the solid waste be disposed of (describe)?

N/A

Where will the solid waste be disposed if it does not feed into a municipal waste stream (describe)?

N/A


22

If the solid waste (construction or operational phases) will not be disposed of in a registered landfill site or be taken up in a municipal waste stream, then the applicant should consult with the competent authority to determine whether it is necessary to change to an application for scoping and EIA.

Can any part of the solid waste be classified as hazardous in terms of the relevant legislation?

YES �� NO

If yes, inform the competent authority and request a change to an application for scoping and EIA.

Is the activity that is being applied for a solid waste handling or treatment facility?

YES �� NO

If yes, then the applicant should consult with the competent authority to determine whether it is necessary to change to an application for scoping and EIA. 11(b) Liquid effluent

Will the activity produce effluent, other than normal sewage, that will be disposed of in a municipal sewage system?

YES �� NO

If yes, what estimated quantity will be produced per month? N/A

Will the activity produce any effluent that will be treated and/or disposed of on site?

Yes �� NO

If yes, the applicant should consult with the competent authority to determine whether it is necessary to change to an application for scoping and EIA.

Will the activity produce effluent that will be treated and/or disposed of at another facility?

YES �� NO

If yes, provide the particulars of the facility:

Facility name:

Contact person:

Postal address:

Postal code:

Telephone: Cell:

E-mail: Fax:

Describe the measures that will be taken to ensure the optimal reuse or recycling of waste water, if any:

Although no effluent will be disposed on site, adequate measures have to be put in place to ensure that construction workers use portable toilets supplied by contractor. The open veld may not be used for ablutions. The EMP must address the management of this issue.

11(c) Emissions into the Atmosphere

Will the activity release emissions into the atmosphere? YES �� NO

If yes, is it controlled by any legislation of any sphere of government? YES NO


If no, describe the emissions in terms of type and concentration:


23

During the construction phase, it is expected that there will be short-term dust generation and emissions from vehicles and machinery. However, the dust and emissions will have a medium- to short-term duration and have a limited impact on the very immediate surrounding rural areas. Where appropriate, dust suppression measures will be implemented to reduce the impacts. It is recommended that construction vehicles be serviced and kept in good mechanical condition to minimise possible exhaust emission.

11(d) Generation of Noise

Will the activity generate noise? �� YES NO

If yes, is it controlled by any legislation of any sphere of government? YES �� NO


If no, describe the noise in terms of type and level:

Noise control regulations and SANS 10103 Short term noise impacts are anticipated during the construction phase of the project caused by construction vehicles and drilling machines. It is, however, anticipated that the noise will be localised and contained within the construction site. In order to minimise the impacts of noise during the construction phase, construction activities should be restricted to between 07H00 and 17H00, Monday to Friday, and 08H00 - 13H00 on Saturdays. This is required to avoid noise disturbances outside normal working hours. All construction equipment must be maintained and kept in good working order to minimise associated noise impacts. The noise level is anticipated to be less than 50dBA as required by SANS 10103 and thus authorisation will not be required for the noise. 12.

Much of the pristine indigenous vegetation has been transformed by agriculture (i.e. cultivated lands) and settlements in the vicinity of the project and thus the human impact levels on natural vegetation have been very high. Open grasslands that are grazed with domestic stock have been poorly managed in terms of high stocking density and the application of poor burning regimes. This has caused many of the highly palatable grass species (e.g. Themeda triandra) to become replaced with less desirable/ unpalatable grasses (e.g. Aristida sp). Remaining intact patches of indigenous vegetation are therefore of high conservation value as they provide habitat and refuge for the remaining indigenous fauna species in the study area. Three main vegetation types, namely the Ngongoni Veld, Eastern Valley Bushveld and the Southern Mistbelt Forest, dominate the study area and all three are classified as being Least Threatened or Vulnerable. The Eastern Valley Bushveld cover the majority of the study area (Mucina and Rutherford, 2006) and characterise the flanks of most rivers, where Acacias and Euphorbias dominate. The Ngongoni Veld borders the coastal strip. No indigenous mammals were observed during the site visit. Given the high level of anthropogenic disturbance, it is to be expected that populations of indigenous large mammals will be restricted to forests, secluded valleys, proclaimed and fenced protected areas. No such protected areas occur within the immediate study area. The Avifaunal Specialist Report indicated that the proposed route for the powerlines appears to have been well planned and is probably the best possible route in terms of avifaunal impacts.

5. LAND USE CHARACTER OF SURROUNDING AREA Indicate land uses and/or prominent features that currently occur within a 500 m radius of the site and give description of how this influences the application or may be impacted upon by the application: The highlighted sections indicate the relevant landuse 5.1 Natural area �

Refer to Section B4

5.2 Low density residential �

The project will improve power supply to the communities within the study area and provide a number of jobs during the construction phase, thus stimulating the local economy. Non-maintenance of the powerlines may pose safety issue to the communities in terms of fire and electrocutions. The communities may lose land through the development of new servitudes as well as a loss of “sense of place.

5.31 Landfill or waste treatment site 5.32 Plantation 5.33 Agriculture �

Agriculture in the region takes the form of low intensity subsistence agriculture. The proposed powerline will result in the reduction of arable land through the development of new servitudes. The proposed development may however result in improved economic conditions reducing the reliance on subsitance agriculture.

5.34 River, stream or wetland �

The proposed powerline crosses the Mthatha River at approximately 31° 33.886’ S ; 29° 18.764’ E. The proposed development may negatively impact the vegetation and banks of a river system, through disturbance, vegetation clearing, erosion and pollution. However, should ESKOMS “Standard for Bush clearance and maintenance within overhead powerline servitudes” together with the mitigation measures contained within this report be implemented, the impact on the Mthatha River is believed to be low.

PHASE 1 HERITAGE IMPACT ASSESSMENT Findings of the Heritage specialist

eThembeni Cultural Heritage was appointed by GIBB as the Heritage specialist to undertake a

Phase 1 Heritage Impact Assessment (HIA) for this Basic Assessment, in terms of the National

Environmental Management Act 107 of 1998 as amended, in compliance with Section 38 of the

National Heritage Resources Act 25 of 1999, as amended.

The Heritage specialist observed no visually sensitive categories of heritage resource within the

proposed development corridor. However, they did notice various abandoned homesteads around and

between existing villages that probably date to before the establishment of the aforementioned villages

and may include ancestral graves.

Furthermore, the colluvial plain adjacent to the Mgazi River and its tributaries has potential to contain Early and Late Iron Age archaeological remains (Prins et al 1993). However, these have in all likelihood been largely removed from primary context by successive deep-disc ploughing episodes over the last 45 years. eThembeni Cultural Heritage recommended the following mitigation measures:

−−−− That tower placements should be negotiated with residents to ensure that no ancestral graves

are affected.

−−−− Any observed archaeological remains should be reported as per the protocol indicated below.

Protocol for the identification, protection and recovery of heritage resources during construction and operation


31

It is possible that sub-surface heritage resources will be encountered during the construction phase of

this project. The Project Engineer, Environmental Control Officer (ECO) and all other persons

responsible for site management and excavation should be aware that indicators of sub-surface sites

could include:

− Ash deposits (unnaturally grey appearance of soil compared to the surrounding substrate);

− Bone concentrations, either animal or human;

− Ceramic fragments, including potshards;

− Stone concentrations that appear to be formally arranged (may indicate the presence of an

underlying burial); and

− Fossilised remains of fauna and flora, including trees.

In the event that such indicator(s) of heritage resources are identified, the following actions should be

taken immediately:

− All construction within a radius of at least 20m of the indicator should cease. This distance

should be increased at the discretion of supervisory staff if heavy machinery or explosives

could cause further disturbance to the suspected heritage resource.

− This area must be marked using clearly visible means, such as barrier tape, and all personnel

should be informed that it is a no-go area.

− A guard should be appointed to enforce this no-go area if there is any possibility that it could

be violated, whether intentionally or inadvertently, by construction staff or members of the

public.

− No measures should be taken to cover up the suspected heritage resource with soil, or to

collect any remains such as bone or stone.

− If a heritage practitioner has been appointed to monitor the project, s/he should be contacted

and a site inspection arranged as soon as possible.

− If no heritage practitioner has been appointed to monitor the project, Dr Mariagrazia Galimberti

at SAHRA’s Cape Town head office should be contacted (telephone 021 462 4502).

− The South African Police Services should be notified by a SAHRA staff member or an

independent heritage practitioner if human remains are identified. No SAPS official may

disturb or exhume such remains, whether of recent origin or not.

− All parties concerned should respect the potentially sensitive and confidential nature of the

heritage resources, particularly human remains, and refrain from making public statements

until a mutually agreed time.

Any extension of the project beyond its current footprint involving vegetation and/or earth clearance should be subject to prior assessment by a qualified heritage practitioner, taking into account all information gathered during this initial heritage impact assessment. Conclusion

eThembeni Cultural Heritage recommend that the development proceed with the proposed heritage

mitigation. They have submitted this report to SAHRA in fulfilment of the requirements of the NHRA.


32

According to Section 38(4) of the Act the report shall be considered timeously by the Council which

shall, after consultation with the person proposing the development, decide –

− whether or not the development may proceed;

− any limitations or conditions are to be applied to the development;

− what general protections in terms of this Act apply, and what formal protections may be

applied to such heritage resources;

− whether compensatory action shall be required in respect of any heritage resources damaged

or destroyed as a result of the development; and

− whether the appointment of specialists is required as a condition of approval of the proposal.

If permission is granted for development to proceed, the client is reminded that the NHRA requires that a developer cease all work immediately and follow the protocol contained in the section above (Protocol for the identification, protection and recovery of heritage resources during construction and operation) should any heritage resources, as defined in the Act, be discovered during the course of development activities.

PALAEONTOLOGICAL IMPACT ASSESSMENT Findings of the Palaeological specialist

Rob Gess Consulting was appointed by GIBB as the Palaeontological Impact Assessment as part of

the Heritage Impact Assessment (HIA) for this Basic Assessment, in terms of the National

Environmental Management Act 107 of 1998 as amended, in compliance with Section 38 of the

National Heritage Resources Act 25 of 1999, as amended.

The Palaeontological Specialist identified that the proposed development would transverse land

underlain by strata belonging to the Karoo Supergroup. The Karoo Supergroup consist of mudstones

and sandy mudstones of the Ecca Group as well as dolerite intrusions emplaced during extrusion of

the Drakensberg Group. Due to the nature of the dolerites, no fossils are present. The alluvium

consisting of unconsolidated silt from large floodplains located adjacent to major rivers is also not

considered to be palaeontologically sensitive.

Course grained exposures of sandy Ecca Group was found to be exposed near Tombo. These

sediments were found to contain only small fragments of plants and are said to be of little

palaeontological importance. As the powerline descends northwards outcrops of resilient Ecca Group

rock were identified, of which were not found to be visually fossiliferous. The powerline then follows the

vally of the Mngazi River where outcrops were covered by thick deposits of Quaternary sand and silt

which are agin not considered to be palaeontologically sensitive. As the powerline leaves the Mnagzi

River valley towards Mafini it transverses a south facing slope characterised by weathered ridges of

resilient dolerite. A small out crop of Ecca Group sediments was again identified a short distance from

the north western end of the route. These sediments consisted of more fine grained mudstones then

the sediments encountered elsewhere along the study area and only fragmented plant remains were

observed.


33

Conclusion

The powerline route is underlain by Ecca Group sandstones and mudstones, dolerite intrusions and

recent alluvium. Only the Ecca Group strata are potentially palaeontologically sensitive, with only small

fragments of plant stems identified.

The palaeontologist believes it is extremely unlikely that significant paleontological material will be

disturbed during the erection of the powerline.

The following recommendations have been proposed:

1. Monitoring of the works by a palaeontologist is not required; and

2. The ECO should be notified to be on the lookout for any mudstone layers containing mats of

fossil plants, where Ecca Group rocks are disturbed, and should notify SAHRA and/ or a

qualified palaeontologist should such be exposed.

• Topsoil should be spread over landscaped areas.

• According to specifications by Eskom’s landscape architect, the area should be re-vegetated upon completion of construction activities.

• Vehicle access to the power line servitude must as far as possible be limited to existing roads. If new access roads need to be constructed, they should follow cleared areas such as cattle pathways.

• The Contractor will properly mark all access roads.

• Markers will show the direction of travel as well as tower numbers to which the road leads.

• Roads not to be used will be marked with a "NO ENTRY" sign. Unnecessary traversing of land is discouraged. Where required, speed limits will be indicated on the roads (30 km). All speed limits will be strictly adhered to at all times.

• Strict control should be implemented over all activities during construction to ensure disturbance to social and ecological components is kept to a minimum.

• The full depth of topsoil should be stripped from areas affected by construction and related activities prior to the commencement of major earthworks. This should include the building footprints, working areas and storage areas.

• Topsoil must be reused where possible to rehabilitate disturbed areas.

• Care must be taken not to mix topsoil and subsoil during stripping.

• No soil stripping must take place on areas within the site that the contractor does not require for construction works, or on areas of retained vegetation.

• Subsoil and overburden should, in all construction and lay-down areas, be stockpiled separately to be returned for backfilling in the correct soil horizon order.

• Stockpiles should not be situated such that they obstruct natural water pathways and drainage channels.

• If stockpiles are exposed to windy conditions or heavy rain, they should be covered either by vegetation or cloth.

• Stockpiles may further be protected by the construction of berms or low brick walls around their bases.

• Stockpiles should be kept clear of weeds and alien vegetation growth by regular weeding.

• The site must be managed in a manner that prevents pollution of downstream watercourses or groundwater, due to suspended solids, silt or chemical pollutants.

• Temporary cut-off drains and berms may be required to capture stormwater and promote infiltration.

• Hazardous Chemical Substances Regulations promulgated in terms of the Occupational Health and Safety Act 85 of 1993 and the SABS Code of Practise must be adhered to. This applies to solvents and other chemicals possibly used in the construction time.

• Staff that will be handling hazardous materials must be trained to do so. Hazardous Chemical Substances Regulations promulgated in terms of the Occupational Health and Safety Act 85 of 1993 and the SABS Code of Practise must be adhered to. This applies to solvents and other chemicals possibly used in the construction time

• Depending on the nature and extent of the spill, contaminated soil must be either excavated or treated on-site.

• The ECO must determine the precise method of treatment of polluted soil.

• This could involve the application of soil absorbent materials or oil-digestive powders to the contaminated soil.

• If a spill occurs on an impermeable surface such as cement or concrete, the surface spill must be contained using oil absorbent materials.


40

• Contaminated remediation materials must be carefully removed from the area of the spill so as to prevent further release of petrochemicals into the environment, and stored in adequate containers until appropriate disposal.

• The individual responsible for or who discovers the petrochemical spill must report the incident to the Project Co-ordinator, ECO and/or Contractor as soon as reasonably possible.

• Any spills are to be immediately assessed and the necessary actions undertaken to contain and remediate the spill.

• No vehicles transporting concrete to the site may be washed on site.

• If a batching plant is necessary, run-off should be managed effectively to avoid contamination of other areas of the site.

• All construction staff must be trained in fire hazard control and fire-fighting techniques.

• All flammable substances must be stored in dry areas which do not pose an ignition risk.

• No open fires will be allowed on site unless in a demarcated area identified by the ECO.

• Smoking may only be conducted in demarcated areas as agreed upon by the ECO and contractor.

• All cooking will be done in demarcated areas that are safe in terms of runaway or uncontrolled fires.

• The Contractor will have operational fire-fighting equipment available on site at all times. The level of fire-fighting equipment must be assessed and evaluated through a typical risk assessment process. It may be required to increase the level of protection, especially during the winter months.

• Adequate sanitary and ablutions facilities must be provided for construction workers and serviced regularly.

• The facilities must be regularly serviced to reduce the risk of surface or groundwater pollution.

• Contaminated wastewater must be managed by the Contractor to ensure existing water resources on the site are not contaminated. All wastewater from general activities in the camp will be collected and removed from the site for appropriate disposal at a licensed commercial facility.

• Heavy vehicle traffic should be routed away from noise sensitive areas, where possible.

• Noise levels must be kept within acceptable limits. All noise and sounds generated must adhere to SABS 0103 specifications for maximum allowable noise levels for residential areas. No pure tone sirens or hooters may be utilised except where required in terms of SABS standards or in emergencies.

• Noisy activities to take place during allocated construction hours only as per Section 25 of the Noise Control Regulations of the Environment Conservation Act, 1989 (Act No. 73 of 1989).

• Construction rubble will be disposed of in pre–agreed, demarcated spoil dumps that have been approved by the Municipality.

• Continued care should be taken to observe any sites of heritage significance during operation. Should any archaeological artefacts and palaeontological remains be exposed during operations, work on the area where the artefacts were found will cease immediately and the appropriate person will be notified as soon as possible.

• Any discovered artefacts will not be removed under any circumstances. Any destruction of a site can only be allowed once a permit is obtained from SAHRA and the site has been mapped and noted.

• Under no circumstances will archaeological or palaeontological artefacts be removed, destroyed or interfered with by anyone on the site during operations.

• The operator will advise its workers of the penalties associated with the unlawful removal of cultural, historical, archaeological or palaeontological artefacts, as set out in the National Heritage Resources Act (Act No. 25 of 1999), Section 51(1).

• The rehabilitation of the trenches and disturbed areas around the power line must be done with indigenous grasses local to the area and that require minimal horticultural maintenance.

• All weeds and invasive vegetation should be eradicated over a five year period.

• Dust suppression measures need to be implemented on site when necessary to reduce the dust


41

impacts.

• Waste managed accordingly and collected regularly to prevent accumulation on site.

MITIGATION MEASURES

• Access to the power line servitude must be restricted. Ideally this should be done by fencing off and gating along the main access roads.

• Regular inspection of the power line must take place to monitor its operational status

• Once built and commissioned, periodic maintenance will be undertaken repairing faults, and broken infrastructure.

• The development must be screened by vegetation where practically feasible to limit the visual impact

• Ensure all development takes place in accordance with relevant policies and guidelines

• During this phase it is essential that all maintenance personnel undertake general best practice environmental management including:

� Keeping to existing access roads and no “open bush” driving;

� No littering or disturbance to surface water features (where relevant); and

� Closing gates and general respect for property. NO-GO ALTERNATIVE

Failure to install the proposed power line may result in significantly longer power outages when failures in the supply network occur as it will not be possible to utilise remote switching control between circuits / substations. This option is not a feasible or reasonable alternative.

DECOMMISSIONING AND CLOSURE PHASE

The decommissioning and closure phase for the substation is anticipated to be within 25-30 years from development of the facility. Should the facility be decommissioned it is anticipated that the installation will be removed from the site or upgraded.

47

Alternative A (preferred alternative)

Option 1 is preferred route alignment because it presents Low environmental impacts with mitigation. According to the Avifaunal specialist study the preferred alternative appears to have been well planned and is probably the best possible route in terms of avifaunal impacts. In terms of ecological factors, the preferred alternative is favoured as it avoids the patches of indigenous forests and other sensitive micro habitats that exist within the study area. According to the Heritage Impact Assessments, including Archaeological and Palaeontological aspects, it is unlikely that the preferred alternative will disturb any significant palaeontological or archaeological material.

Alternative B (Minor alternative)

The minor alternative has very little bearing on the anticipated impacts. The impacts are therefore envisaged to be the same as the preferred alternative.

No-go Alternative (compulsory)

The provision of a non-interrupted power supply is essential for economic development of the area. The no-go alternative is not a viable option.

SECTION E. RECOMMENDATION OF PRACTITIONER

Is the information contained in this report and the documentation attached hereto sufficient to make a decision in respect of the activity applied for (in the view of the Environmental Assessment Practitioner)?

YES �

NO

If “NO”, indicate the aspects that should be assessed further as part of a Scoping and EIA process before a decision can be made (list the aspects that require further assessment):

N/A

If “YES”, please list any recommended conditions, including mitigation measures that should be considered for inclusion in any authorisation that may be granted by the competent authority in respect of the application:

• All mitigation measures proposed in the report form part of the EMPr and adherence to the specifications of the EMPr should form part of the conditions of the environmental authorisation, should this be granted

• An Independent Environmental Control Officer (ECO) must be appointed for the construction of the proposed development to monitor compliance to EMPr

• The EMPr must be adhered to by the contractor under, the supervision of the engineer and an ECO.

• the ECO audits must include: � A monthly compliance audit - with the first audit being conducted no later than

one month after construction commences on site; and � A post construction (rehabilitation) compliance audit is to be conducted no

later than two weeks before the contractor hands over the completed project. • Pylons are to be fitted with perching brackets and the sensitive areas identified in the

avifaunal report. • Valley areas including the river crossing, should be marked with suitable anti-collision

marking devices. • An avifaunal walk-through should be undertaken once the exact tower positions are

surveyed and finalised. • Indigenous forest areas are to be completely avoided by the powerline and labour teams. • Soils compacted by construction activities are to be ripped. • Topsoil is to be stripped from all areas affected by construction and related activities prior

to the commencement of major earthworks and conserved for rehabilitation. • Should any archaeological or palaeontological remains be exposed during operations,

work on the area where the artefacts were found must cease immediately and the appropriate specialist will be notified as soon as possible.

In the opinion of the Environmental Practitioner, the proposed activity is not fatally flawed and all potential impacts can be mitigated to an acceptable level. As such, it is recommended that the proposed construction of the power line continue if all recommendations and mitigation measures are followed.

APPENDIX E: COMMENT AND RESPONSES REPORT

PUBLIC PARTICIPATION The purpose of involvement of Stakeholders and Interested and Affected Parties (I&APs) is to allow them to voice their opinions and concerns of the proposed project. Such engagement is critical as it contributes to a better understanding of the proposed project among I&APs, and raises important issues that need to be assessed in the EIA process. There are four key steps within the overall public participation process. These include - • Notifying I&APs of the EIA; • Holding public and focus group meetings; • Making provision for I&APs to review and comment on all reports before they are finalised and

submitted to the competent authority; and • Making a record of responses to comments and concerns available to I&APs. Prior to the preparation of this Draft Basic Assessment Report (BAR), the above steps have comprised the activities described in Sections below. This Draft BAR will be made available for inspection by all registered I&APs for a period of 30 days. The draft report will be available at strategic places that are easily accessible by the public, such as public libraries and community centres. Comments received will be considered, and necessary changes made to the draft before it is submitted for review to the competent authority as the final BAR. Comments received from I&APs during the review period will be recorded, responses will be prepared, and a record of comments and responses will be maintained.

In terms of the EIA Regulations (2 010), PPP is required to provide: Details of the public participation process conducted, including: (a) fixing a noticeboard at a place conspicuous to the public at the boundary or on the fence

of— (i) the site where the activity to which the application relates is or is to be undertaken; and (ii) any alternative site mentioned in the application;

(b) giving written notice to— (i) the owner or person in control of that land if the applicant is not the owner or

person in control of the land; (ii) the occupiers of the site where the activity is or is to be undertaken or to any

alternative site where the activity is to be undertaken; (iii) owners and occupiers of land adjacent to the site where the activity is or is to be

undertaken or to any alternative site where the activity is to be undertaken; (iv) the municipal councillor of the ward in which the site or alternative site is situated

and any organisation of ratepayers that represent the community in the area; (v) the municipality which has jurisdiction in the area; (vi) any organ of state having jurisdiction in respect of any aspect of the activity; and (vii) any other party as required by the competent authority;

(c) placing an advertisement in— (i) one local newspaper; or and affected parties;

Notifying Interested and Affected P Newspaper Advertisement The proposed activity was advertised in the Daily Dispatch on advertisement detailed the proposed development and provided Interested & Affected Parties (I&APs) 30 days to register.
