The growing demand for electricity is placing increasing pressure on Eskom’s existing power generation and transmission capacity. Eskom is committed to implementing a Sustainable Energy Strategy that complements the policies and strategies of National Government. Eskom aims to improve the reliability of electricity supply to the country, and in particular to provide for the growth in electricity demand in the Gauteng and Mpumalanga provinces. For this reason, Eskom obtained environmental authorisation to construct the new Kusile Power Station between Bronkhorstspruit and Witbank in 2007. Construction of this power station has already commenced.

The new Kusile Power Station requires the delivery of coal to the plant as an energy source in the power generation process. Anglo Coal is proposing the establishment of the New Largo Coal Mine adjacent to the Kusile Power Station. At present the Duvha-Minerva 400 kV power line traverses over the land earmarked for mining in 2013. Anglo Coal has requested that the existing line be deviated around the mining area in order to safely supply coal to the Kusile Power Station.

Eskom’s Transmission Division appointed Zitholele Consulting (Pty) Ltd, an independent company, to conduct an EIA to evaluate the potential environmental and social impacts of the proposed project. As part of the environmental process specialist assessments have to be undertaken in order to inform the Impact Assessment Phase. This report details the findings the terrestrial ecology, soil, agricultural potential, wetland delineation and visual specialist assessments.

Zitholele Consulting have undertaken the aforementioned studies. The purpose of this document is therefore to present the findings from these assessments and to provide impact assessments and mitigation measures for each of the biophysical elements.

1 INTRODUCTION

1.1 PROJECT BACKGROUND

The growing demand for electricity is placing increasing pressure on Eskom’s existing power generation and transmission capacity. Eskom is committed to implementing a Sustainable Energy Strategy that complements the policies and strategies of National Government. Eskom aims to improve the reliability of electricity supply to the country, and in particular to provide for the growth in electricity demand in the Gauteng and Mpumalanga provinces. For this reason, Eskom obtained environmental authorisation to construct the new Kusile Power Station between Bronkhorstspruit and Witbank in 2007. Construction of this power station has already commenced.

The new Kusile Power Station requires the delivery of coal to the plant as an energy source in the power generation process. Anglo Coal is proposing the establishment of the New Largo Coal Mine adjacent to the Kusile Power Station. At present the Duvha-Minerva 400 kV power line traverses over the land earmarked for mining in 2013. Anglo Coal has requested that the existing line be deviated around the mining area in order to safely supply coal to the Kusile Power Station.

At present four route alternatives are being investigated, varying in length from 11 – 14 km, namely (Figure 1-1):

Deviation - Alternative 1

Alternative 1 exits the existing 400kV Duvha-Minerva power line at the north of the Eskom property, located 3 km south of the N4 highway. The corridor heads in a north easterly direction (~3.5km) towards the newly constructed 132kV distribution power line. Thereafter alternative 1 follows the exact alignment of the newly constructed 132kV distribution power line (~10km) before meeting the existing 400kV Duvha-Minerva power line (total length ~ 13.5 km).

Deviation - Alternative 2

Alternative 2 follows the same alignment as alternative 1 except 2.5km before re-joining the existing 400kV Duvha-Minerva power line, the alternative follows a straight south easterly path to the existing transmission line avoiding an additional bend tower (total length ~ 13.4 m).

Deviation - Alternative 3

Alternative 3 exits the existing 400kV Duvha-Minerva power line at the north of the Eskom property approximately 900m south east from alternative 1 starting point. Alternative 3 heads in a north easterly direction (~3.5km) crossing the 545 road and thereafter bending eastwards (~800m) before joining the newly constructed 132kV distribution power line (total length ~ 11.8 km).

Deviation - Alternative 4

Alternative 4 exits the existing 400kV Duvha-Minerva power line at the same location as alternative 3. The alternative heads in a south easterly direction (~1km) before crossing over the newly constructed 132kV distribution power line. Thereafter the alternative heads in a north easterly direction (~ 5km) before joining the newly constructed 132kV distribution power line (total length ~ 11.8 km).

1.2 STUDY SCOPE

Eskom’s Transmission Division has appointed Zitholele Consulting (Pty) Ltd (Zitholele Consulting), an independent company, to conduct an EIA to evaluate the potential environmental and social impacts of the proposed project. As part of the environmental impact assessment for the aforementioned project it is required that certain biophysical specialist investigations are undertaken. Zitholele Consulting was appointed to undertake the following biophysical specialist studies:

Wetlands and Surface Water;

Topography and Visual Impact;

Soils and Agricultural Potential; and

Terrestrial Ecology.

1.3 STUDY APPROACH

The study approach consisted of a desktop study followed by detailed site investigation. The desktop study involved using existing GIS data and existing literature on the study are. These included the studies undertaken for the Kusile Power Station EIA, the Kusile Railway EIA and the New Largo Coal Mine EIA.

The specialist studies were undertaken during site visits conducted from the 25th February – 2nd March 2011. The site visits were undertaken at this time of year to ensure that species were easily identifiable. The study area encompasses the area within a 5 00 m radius of the proposed power line alternatives. At 150m intervals along the power line alternatives a transect was surveyed across the corridor. In areas where there are more sensitive features such as wetlands and stream crossings the area was studied in more detail. At each of the transects the vegetation, soil, fauna and wetland characteristics were sampled.

Once all the information was gathered on site the information was summarised in a biophysical report (this report).

2 BIOPHYSICAL RECEIVING ENVIRONMENT

This section details the receiving environment at the project location. For the context of this report the regional environment refers to a 50 km radius around the study area.

Although the aim of this report is to detail the vegetation, wetlands, soil and land capability component of the receiving environment; certain additional factors have been included, as they provide perspective to the soil and vegetation study. These include geology, topography, climate, surface water and land use.

2.1 TOPOGRAPHY

2.1.1 Data Collection

The topography data was obtained from the Surveyor General’s 1:50 000 toposheet data for the region, namely 2529CC and 2528DD. Contours were combined from the topographical mapsheets to form a combined contours layer. Using the Arcview GIS software the contour information was used to develop a digital elevation model of the region as shown in Figure 2-1 below.

2.1.2 Regional Description

The topography of the region is gently undulating to moderately undulating landscape of the Highveld plateau. Some small scattered wetlands and pans occur in the area, rocky outcrops and ridges also form part of significant landscape features in the area. Altitude ranges between 1 360 – 1 600 metres above mean sea level (mamsl). Figure 2-1 provides an illustration of the topography of the site. With regards to ridges, a small koppie occurs to the north of the site and all the routes traverse just to the south of this koppie.

2.2 SOILS

2.2.1 Data Collection

The site visit was conducted in February – March 2011. Soils were augered at 200m intervals along the proposed railway line routes using a 150 mm bucket auger, up to refusal or 1.2 m. Soils were identified according to Soil Classification; a taxonomic system for South Africa (Memoirs on the Natural Resources of South Africa, no. 15, 1991). The following soil characteristics were documented:

Soil horizons;

Soil colour;

Soil depth;

Soil texture (Field determination);

Wetness;

Occurrence of concretions or rocks; and

Underlying material (if possible).

2.2.2 Regional Description

The soils in the region are mostly derived from the geology of the region namely, predominantly shale (Silverton formation), sandstone conglomerate (Wilgerivier formation), siltstone (Dwyka formation) or diabase intrusions which feature prominently in the area. The soils are generally shallow with a yellow-brown colour.

2.2.3 Site Description

During the site visit large quantities of soil forms were identified. The soils forms were grouped into management units and are described in detail in the sections below and Figure 2-2 illustrates the location of the soil types. The land capability (agricultural potential) of the abovementioned soil form is described in more detail in Section 2.3.

The management units are broken up into:

Deep Soils;

Clay Soils;

Rocky Soils;

Transitional Soils; and

Disturbed Soils.

Rocky Soils

The rocky soils are generally shallow and that overlie an impeding layer such as hard rock or weathering saprolite. These soils are not suitable for cultivation and in most cases are only usable as light grazing. The main soil forms found in rocky soils were Mispah and Glenrosa, each form is described below.

Mispah soil form

The Mispah soil form is characterised by an Orthic A – horizon overlying hard rock. Mispah soil is horizontally orientated, hard, fractured sediments which do not have distinct vertical channels containing soil material. There is usually a red or yellow-brown apedal horizon with very low organic matter content. Please refer to Figure 2-3 for an illustration of a typical Mispah soil form.

Figure 2-3: Mispah soil form (Soil Classification, 1991).

Glenrosa Soil Form

The Glenrosa soil form is a combination of an Orthic A horizon overlying a lithocutanic

B horizon as indicated in Figure 2-4 below. A lithocutanic B has several characteristics that separate it from other horizons, namely:

It merges into the underlying weathering rock;

Has a general organisation in respect of colour, structure or consistency that has distinct affinities with the underlying parent rock;

March 2011 10 12627

ZITHOLELE CONSULTING

Has cutanic character expressed usually as tongues or prominent colour variations caused by residual soil formation and illuviation resulting in localization of one or more of clay, iron and manganese oxides;

Lacks a laterally continues horizon which would qualify as either a diagnostic podzol B, neocarbonate B, pedocutanic B, pedocutanic B, hardpan carbonate or dorbank; and

If the horizon shows signs of wetness, then more than 25% by volume has saprolitic character.

Figure 2-4: Glenrosa Soil Form (Soil Classification, 1991)

Agricultural Soils

The agricultural soils found on site support an industry of commercial maize production. These soils include Clovelly and Avalon. These soils have deep yellow-brown B-horizons with minimal structure. These soils drain well and provide excellent to moderate cultivation opportunities. Each of the soils is described in detail below.

Clovelly Soil Form

Clovelly soils can be identified as an apedal “yellow” B-horizon as indicated in Figure 2-5 below. These soils along with Hutton soils are the main agricultural soil found within South Africa, due to the deep, well-drained nature of these soils. The soils are found on the valley slopes of the site.

ZITHOLELE CONSULTING

Figure 2-5: Clovelly soil form (Soil Classification, 1991)

Avalon Soil Form

The Avalon soil form is characterised by the occurrence of a yellow-brown apedal B-horizon over a soft plinthic B – horizon (See Figure 2-6). The yellow-brown apedal horizon is the same as described for the Clovelly soil form and the plinthic horizon has the following characteristics:

Has undergone localised accumulation of iron and manganese oxides under conditions of a fluctuating water table with clear red-brown, yellow-brown or black strains in more than 10% of the horizon;

Has grey colours of gleying in or directly underneath the horizon; and

Does not qualify as a diagnostic soft carbonate horizon.

These soils are found between lower down the slopes than the Clovelly soils and indicate the start of the soils with clay accumulation.

Figure 2-6: Avalon Soil Form (Soil Classification, 1991)

Transitional Soils

The transitional soil management unit comprises the soils found between clay soils and the agricultural soils. These soils often have signs of clay accumulation or water movement in the lower horizons. These soils are usually indicative of seasonal or temporary wetland conditions. The main soil forms found in transitional soils were Kroonstad, Wasbank, Longlands and Westleigh, each form is described below.

Kroonstad Soil Form

The Kroonstad soil form is most commonly found in areas of semi-permanent wetness. The soil is made up of an Orthic A horizon over a diagnostic E-horizon over a G-horizon, as indicated in Figure 2-7 below. The G-horizon has several unique diagnostic criteria as a horizon, namely:

The Wasbank soil form is found in close proximity to the Longlands soil form and is typified by an Orthic A-horizon over an E-horizon (as described above) over a Hard Plinthic B-horizon. The Hard Plinthic B-horizon develops when a Soft Plinthic horizon is subjected to a prolonged dry period and the accumulated colloidal matter hardens, almost irreversibly. The Wasbank soil form is illustrated in Figure 2-10 below.

Westleigh Soil Forms

Westleigh soils are characterised by an orthic A-horizon over a soft plinthic B-horizon and is found in areas between good agricultural soils and clay soils and the movement of water determines the characteristics of the soil.

Figure 2-11: Westleigh Soil Form (Soil Classification 1991)

Clay Soils

The clay soil management unit is found in areas where clays have accumulated to such an extent that the majority of the soil matrix is made up of clay particles. These soils are usually indicative of seasonal or permanent wetland conditions. The main soil forms found in clay soils were Katspruit and Willowbrook, each form is described below. These soils are saturated with water and must be noted to be unstable for construction and are sensitive.

Katspruit Soil Form

The Katspruit soil form is most commonly found in areas of semi-permanent wetness. The soil is made up of an Orthic A-horizon over a diagnostic G-horizon and is indicated in Figure 2-12 below. The G-horizon has several unique diagnostic criteria as a horizon, namely:

It is saturated with water for long periods unless drained;

Is dominated by grey, low chroma matrix colours, often with blue or green tints, with or without mottling;

Has not undergone marked removal of colloid matter, usually accumulation of colloid matter has taken place in the horizon;

2.3 AGRICULTURAL POTENTIAL (LAND CAPABILITY)

2.3.1 Data Collection

A literature review was conducted in order to obtain any relevant information concerning the area, including information from the Environmental Potential Atlas (ENPAT), Weather Bureau and Department of Agriculture. Results from the soil study were taken into account when determining the agricultural potential also known as the land capability of the site. The land capability assessment methodology as outlined by the National Department of Agriculture was used to assess the soil’s capability to support agriculture on site.

2.3.2 Regional Description

The regional land capability is mostly Class II (Agricultural) soils with few limitations. This is evident in the large number of cultivated lands found in the region. In the areas where the soil is too shallow or too wet to cultivate, livestock are grazed.

2.3.3 Site Description

According to the land capability methodology, the potential for a soil to be utilised for agriculture is based on a wide number of factors. These are listed in the table below along with a short description of each factor.

Table 2-1: Agricultural Potential criteria

Criteria Description

Rock Complex If a soil type has prevalent rocks in the upper sections of the soil it is a limiting factor to the soil’s agricultural potential

Flooding Risk The risk of flooding is determined by the closeness of the soil to water sources.

Erosion Risk The erosion risk of a soil is determined by combining the wind and water erosion potentials.

Slope The slope of the site could potentially limit the agricultural use thereof.

Texture The texture of the soil can limits its use by being too sandy or too clayey.

Depth The effective depth of a soil is critical for the rooting zone for agricultural crops.

Drainage The capability of a soil to drain water is important as most grain crops do not tolerate submergence in water.

Mechanical Limitations Mechanical limitations are any factors that could prevent the soil from being tilled or ploughed.

pH The pH of the soil is important when considering soil nutrients and hence fertility.

Soil Capability This section highlights the soil type’s capability to sustain agriculture.

Climate Class The climate class highlights the prevalent climatic conditions that could influence the agricultural use of a site.

Land Capability / Agricultural Potential

The land capability or agricultural potential rating for a site combines the soil capability and the climate class to arrive at the sites potential to support agriculture.

The soils identified in Section 2.2 above were classified according to the methodology proposed by the Agricultural Research Council – Institute for Soil, Climate and Water (2002). The criteria mentioned above were evaluated in the table below. The site is made up of two main land capability classes, namely Class II – cultivation and Class VIII – rocky grazing. The Class II soils are suitable for cultivation and can be used for a range of agricultural applications. The Class VIII soils have continuing limitations that cannot be corrected; in this case rock complexes, flood hazard, stoniness, and a shallow rooting zone constitute these limitations. Figure 2-14 illustrates the various land capability units on site.

Alternative 4 4.5 1.62 5.9 1.19

From the table above it is clear that the difference between the potential alignments is negligible. With the power lines able to span between 300 and 400 metres between pylons, the difference will be a pylon or two per route.

2.4 SURFACE WATER

2.4.1 Data Collection

The surface water data was obtained from the WR90 database from the Water Research Council. The data used included catchments, river alignments and river names. In addition water body data was obtained from the CSIR land cover database (1990) to illustrate water bodies and wetlands. This data was supplemented with site observations during the various site visits.

2.4.2 Site Description

The main drainage feature of the area is the Saalklapspruit which drains in a northerly direction. Several unnamed tributaries are also found in the area. In addition to the streams a few dams can also be found in the region along with a large pan/wetland to the south of the routes as illustrated in Figure 2-15 above. The streams and their associated dams support a number of faunal and floral species uniquely adapted to these aquatic ecosystems and therefore all surface water bodies are earmarked as sensitive features and should be avoided as far as possible.

In terms of the future mining operations, these water features should not be affected as they are outside of the proposed mining reserve. It is anticipated that clean water will be diverted around the mine into these streams to avoid contamination of surface water.

Figure 2-16: Stream crossing within one of the streams on site.

From Figure 2-15 above, it is clear that all the alternatives cross a stream or river at some point. In actual fact the alternatives are so closely spaced to each other that there is no difference between the alternatives in terms of the number of stream crossings. In terms of the crossing angle, it is always best to cross a wetland or stream at a right angle to minimise the area that is crossed. In this case Alternatives 1 and 2 provide the best options as they cross most of the streams at right angles.

2.5 WETLAND DELINEATION

2.5.1 Data Collection and Methodology

Riparian Zones vs. Wetlands

Wetlands

The riparian zone and wetlands were delineated according to the Department of Water Affairs (DWA, previously known as the Department of Water Affairs and Forestry -DWAF) guideline, 2003: A practical guideline procedure for the identification and delineation of wetlands and riparian zones. According to the DWA guidelines a wetland is defined by the National Water Act as:

“land which is transitional between terrestrial and aquatic systems where the water table is usually at or near surface, or the land is periodically covered with shallow water, and which land in normal circumstances supports or would support vegetation typically adapted to life in saturated soil.”

In addition the guidelines indicate that wetlands must have one or more of the following attributes:

Wetland (hydromorphic) soils that display characteristics resulting from prolonged saturation;

The presence, at least occasionally, of water loving plants (hydrophytes); and

A high water table that results in saturation at or near surface, leading to anaerobic conditions developing in the top 50 centimetres of the soil.

During the site investigation the following indicators of potential wetlands were identified:

Terrain unit indicator;

Soil form indicator;

Soil wetness indicator; and

Vegetation indicator.

Riparian Areas

According to the DWA guidelines a riparian area is defined by the National Water Act as:

“Riparian habitat includes the physical structure and associated vegetation of the areas associated with a watercourse which are commonly characterised by alluvial soils, and which are inundated or flooded to an extent and with a frequency sufficient to support vegetation of species with a composition and physical structure distinct from those of adjacent land areas”

March 2011 24 12627

ZITHOLELE CONSULTING

The difference between Riparian Areas and Wetlands

According to the DWA guidelines the difference between a wetland and a riparian area is:

“Many riparian areas display wetland indicators and should be classified as wetlands. However, other riparian areas are not saturated long enough or often enough to develop wetland characteristics, but also perform a number of important functions, which need to be safeguarded… Riparian areas commonly reflect the high-energy conditions associated with the water flowing in a water channel, whereas wetlands display more diffuse flow and are lower energy environments.”

2.5.2 Delineation

The site was investigated for the occurrence / presence of wetlands and riparian areas, using the methodology described above and described in more detail in the DWA guidelines.

Terrain Unit Indicator

The terrain on site varies from 1 360 mamsl to 1 600 mamsl as illustrated in Figure 2-1. From Figure 2-1 it can be seen that the site is located in an area of undulating hills with the dominant terrain units on site being the midslope, footslope and valley bottom units. According to the DWA guidelines the valley bottom is the terrain unit where wetlands are most likely to occur, but the occurrence of wetlands is not excluded from any of the other terrain units.

Soil Form Indicator

The site is located on a slope that drains towards the Saalklapspruit. Water enters the soils profile and then flows through the profile down-slope. This action of water movement through the slope typifies the soils of the largest part of the site (eluvial and plinthic soils). Closer to the stream (within the valley bottom terrain unit) the soils gradually deepen due to the down-slope transport of soil (colluvium). In addition these soils have gradually higher percentages of clays that over time have been washed down-slope and accumulate at the valley bottom where the slope angle reduces. The detailed soil mapping exercise was limited to the footslope and valley bottom area in order to delineate the wetland / riparian zones.

Of the soils identified on site the Katspruit soil form is indicative of the permanent wetland zone, while the Wasbank and Longlands soil forms are indicative of the temporary wetland zone. There is also a possibility that the Avalon soil form can be indicative of the temporary zone.

Soil Wetness Indicator

The soils on site were subjected to a soil wetness assessment. If soils showed signs of wetness within 50 cm of the soil surface, it was classified as a hydromorphic soil and divided into the following groups:

Page 33: DRAFT BIOPHYSICAL REPORT - zitholele - Duvha/3. Environmental... · DRAFT BIOPHYSICAL REPORT March 2011 ... the New Largo Coal Mine adjacent to the Kusile Power ... Duvha-Minerva

March 2011 25 12627

ZITHOLELE CONSULTING

Temporary Zone

Minimal grey matrix (<10%);

Few high chroma mottles; and

Short periods of saturation.

Seasonal Zone

Grey matrix (>10%);

Many low chroma mottles present; and

Significant periods of wetness (>3 months / annum).

Permanent Zone

Prominent grey matrix;

Few to no high chroma mottles;

Wetness all year round; and

Sulphuric odour.

The Katspruit, Wasbank and Longlands soil forms have signs of wetness within the top 50 cm of the soil profile. The Avalon soil form however did not have any signs of wetness. The Katspruit soil form was classified as the permanent zone, while the Wasbank and Longlands were classified as the temporary and seasonal zone. The soil forms are illustrated in Figure 2-2.

Vegetation Indicator

The vegetation units on site are described and illustrated in Section 2.6 below. The vegetation found in the moist grassland and the seepage zone vegetation units both have species present to indicate the presence of wetlands.

Delineated Wetlands and Buffer Zones

According to the methodology that was followed for delineation of wetlands by DWA, there are wetlands present on site. It should however be noted that several of the so-called wetlands could also be classified as riparian zones as they follow the drainage path of the non-perennial streams on site. All the area’s identified above perform critical ecosystem functions (water purification, sediment trapping, pollution filtration) and also provide habitat for sensitive species. It is suggested that a 50m buffer be placed from the edge of the temporary zone in order to sufficiently protect the wetlands and riparian zones. Figure 2-17 below illustrates the various wetland zones as well as the buffer placed along the edge of the temporary zone.

2.5.3 Classification of Wetlands

The classification of the wetlands in the study area into different wetland types was based on the WET-EcoServices technique (Kotze et al, 2007). The WET-EcoServices technique identifies seven main types of wetland based on hydro-geomorphic characteristics (Table 2-4).

Table 2-4: Wetland types based on hydro-geomorphic characteristics (Kotze et al, 2007).

Using the methodology above the following wetland types were identified on site as shown below in Figure 2-17:

2.5.4 Wetland Integrity

The Present Ecological Status (PES) Method (DWA 2005) was used to establish the integrity of the wetlands in the study area and was based on the modified Habitat Integrity approach developed by Kleynhans (1996, 1999 In DWA 2005). The delineated wetland units (as described under section 3.2.1.) were used as the basis to divide the wetlands into different segments to increase the resolution of the integrity assessment.

Table 2-5 shows the criteria for assessing the habitat integrity of palustrine wetlands along with Table 2-6 describing the allocation of scores to attributes and the rating of confidence levels associated with each score. These criteria were selected based on the assumption that anthropogenic modification of the criteria and attributes listed under each selected criterion can generally be regarded as the primary causes of the ecological integrity of a wetland.

Table 2-5: Habitat integrity assessment criteria for palustrine wetlands (DWA, 2005). Criteria and Attributes Relevance

The characteristics were scored according to the following general levels of services provided:

Table 2-8: Level of service ratings.

Score Services Rating

0 Low

1 Moderately Low

2 Intermediate

3 Moderately High

4 High

The different wetland units (as delineated under section 2.5) were used as the basis for the level 2 assessment. The assessment was further focussed on those wetland units within the segments of likely impact associated with the different proposed power line routes. The relative importance of the different units, in relation to one another and between the three alternative railway alignments, were then evaluated by summing the number of services regarded as high (scoring levels higher than intermediate). The wetland units with the highest number of important functions were then delineated to facilitate decision making as shown in Figure 2-18. This map indicates that only one area can be deemed pristine with a high integrity rating, and that is the wetland associated with the Saalklapspruit at the southern end of the study area. This area is crossed by all the alternatives, however the shortest crossing is by Alternative 3.

2.6 TERRESTRIAL ECOLOGY

2.6.1 Data Collection

A literature review of the faunal species that could occur in the area was conducted. C-Plan data provided from the Mpumalanga provincial department was used to conduct a desktop study of the area. This data consists of terrestrial components; ratings provide an indication as to the importance of the area with respect to biodiversity.

2.6.2 Regional Description

The biodiversity rating for the bulk of the site (Figure 2-19) is rated as least concern and no natural habitat remaining. The initial stages of Alternatives 1 – 4 are on areas rated as least concern with a bottle neck near the small koppie where the rating is significant due to the potential for red data species, which was confirmed in the vegetation assessment section.

2.6.3 Vegetation

Data Collection

The floral study involved extensive fieldwork, a literature review and a desktop study utilizing GIS. The site was investigated from the 25th February - 2nd March 2011, in late summer. The area within the servitude was sampled using transects placed at 200 m intervals. At random points along the transect an area of 20 m x 20 m was surveyed. All species within the 20 m x 20 m quadrant were identified, photographed and their occurrence noted. Sensitive features such as ridges or wetlands were sampled by walking randomly through the area concerned and identifying all species within the area.

The floral data below is taken from The Vegetation of South Africa, Lesotho and Swaziland (Mucina and Rutherford 2006). Also, while on site, the following field guides were used:

Guide to Grasses of Southern Africa (Frits van Oudtshoorn, 1999); Field Guide to Trees of Southern Africa (Braam van Wyk and Piet van Wyk, 1997); Field Guide to the Wild Flowers of the Highveld (Braam van Wyk and Sasa Malan, 1998); Problem Plants of South Africa (Clive Bromilow, 2001); and Medicinal Plants of South Africa (Ben-Erik van Wyk, Bosch van Oudtshoorn and Nigel Gericke,

2002)

Regional Description

According to the South African National Biodiversity Institute, the study area falls within the Grassland Biome, where most of the country’s maize production occurs. The study area comprises of the Rand Highveld Grassland, Eastern Highveld Grassland and Eastern Temperate Freshwater Wetlands vegetation units as classified by Mucina and Rutherford2. Each of these vegetation units are described in more detail below.

ZITHOLELE CONSULTING

Rand Highveld Grassland

Rand Highveld Grassland is found in the highly variable landscape with extensive sloping plains and ridges in the Gauteng, North-West, Free State and Mpumalanga Provinces. The vegetation type is found in areas between rocky ridges from Pretoria to Witbank, extending onto ridges in the Stoffberg and Roossenekal regions as well as in the vicinity of Derby and Potchefstroom, extending southwards and north-eastwards from there. The vegetation is species rich, sour grassland alternating with low shrubland on rocky outcrops. The most common grasses on the plains belong to the genera Themeda, Eragrostis, Heteropogon and Elionurus. High numbers of herbs, especially Asteraceae are also found. In rocky areas shrubs and trees prevail and are mostly Protea caffra, Acacia caffra, Celtis Africana and Rhus spp.

This vegetation type is poorly conserved (approx 1 %) and has a target of 24 % of the vegetation type to be conserved. Due to the low conservation status this vegetation type is classified as endangered. Almost half of the vegetation type has been transformed by cultivation, plantations, urbanisation or dam-building. Scattered aliens (most prominently Acacia mearnsii) are present in the unit.

Eastern Highveld Grassland

The Eastern Highveld Grassland is found in the Mpumalanga and Gauteng Provinces on the plains between Belfast in the east and the eastern side of Johannesburg in the west and extending southwards to Bethal, Ermelo and west of Piet Retief. The landscape is dominated by undulating plains and low hills with short dense grassland dominating belong to the genera Themeda, Aristida, Digitaria, Eragrostis, Tristachya. Once again woody species are prevalent on the rocky outcrops. In terms of conservation and disturbance, 44 % of the vegetation type is already transformed by cultivation, plantations, mines, and urbanisation. There is no serious alien invasion however Acacia mearnsii dominates in certain areas.

Eastern Temperate Freshwater Wetlands

Another vegetation type associated with the region is the Eastern Temperate Freshwater Wetlands, found around water bodies and embedded within the Grassland biome. Eastern Temperate Freshwater Wetlands are typically found in flat landscapes or shallow depressions filled with (temporary) water bodies supporting zoned systems of aquatic and hydrophillous (water loving) vegetation of temporarily flooded grasslands and ephemeral herblands. Important species include Cyperus congestus, Phragmites australis, Marsilea farinose, Rorippa fluviatalis, Disa zuluensis, Crassula tuberella and the carnivorous herb Utricularia inflexa. These wetlands are one of the most sensitive vegetation units found in the region and have been extensively modified by mining and industrial activities in the region. The vegetation types identified on site are indicated in the Figure below and described in detail below.

Site Description

At the time of the site visit it was found that a large section of the site is already being developed as part of the Kusile Power Station construction as well as numerous sand mining operations on the prevalent sandstone in the area. Information was supplemented with the specialist ecological report1 undertaken for the Kusile Power Station EIA as well as the vegetation report for the New Largo Mine2.

Three main vegetation types were identified, namely rocky grassland, moist grassland and grazed/cultivated fields. Each of these vegetation types are described in more detail below and illustrated in Figure 2-20 above. The species list for the site is attached in Appendix 1. The species that could occur in the quarter degree grid was obtained from the Plants of Southern Africa (POSA) online database upheld by the South African National Botanical Institute (SANBI) and supplemented with field notes. The list provides species names, common names, as well as notes on which species were observed on site. In total 136 species have could occur in the area with 43 confirmed species.

Agriculture

Several areas within the study area are extensively used for cultivation and in this case Zea maize (Maize) is the preferred crop. The soil is tilled annually and with the regular disturbance comes the pioneer plants. In the roadways and fence lines between the fields there is often a collection of weeds and other pioneer plants that flourish before the soil is disturbed again.

Hyparrhenia hirta Anthropogenic Grassland (Grazed and Old Cultivated Fields)

This tall grassland occurs over vast areas, usually on shallow, leached soils on the Johannesburg granite dome, and on undulating north-facing warm andesitic lava slopes of the Suikerbosrand, Witwatersrand and Klipriviersberg areas. Disturbed grassland or other disturbed areas such as road reserves or fallow fields, not cultivated for some years, are also usually Hyparrhenia dominated (Coetzee et al. 1995; Bredenkamp & Brown 2003).

This Hyparrhenia – dominated grassland may appear to be quite natural, but they are mostly associated with an anthropogenic influence from recent or even iron-age times. This grassland is characterised by the tall growing dominant Thatch grass (Hyparrhenia hirta), and Bankrupt Bush (Stoebe vulgaris), an invader dwarf shrub which usually indicates grassland’s degraded condition (Bredenkamp & Brown 2003).

This grassland mostly has low species richness, with only a few other species able to establish or survive in the shade of the dense sward of tall grass. Most of these species are relict pioneers or early seral species. The most prominent species include the grasses Cynodon dactylon, Eragrostis plana, E. racemosa, E. curvula and Aristida congesta. Forbs are rarely encountered, though a few individuals of species such as Anthospermum rigidum, Conyza podocephala, Crabbea angustifolia and Helichrysum rugulosum are often present (Bredenkamp & Brown 2003). Figure 2-22 below provides an illustration of the Hypparrhenia grassland unit with the current Duvha-Minerva power line in the background.

Schizachyrium sanguineum - Loudetia simplex Grassland (Rocky Grassland)

This rocky grassland is found throughout the study area on rocky midslopes of ridges and hills. The soils are often shallow with high rock cover (up to 60% in some cases). This vegetation is found mostly on cooler aspects, but also occur on the warmer north-facing aspects where scattered individuals of dwarf shrubs are present. In some degraded areas Aristida junciformis, A. congesta and Cynodon dactylon are more prominent (Coetzee et al. 1995; Bredenkamp & Brown 2003).

This grassland is dominated by the grasses Digitaria monodactyla, Loudetia simplex, Trachypogon spicatus, Eragrostis racemosa, Andropogon shirensis, Schizachyrium sanguineum, Brachiaria serrata and Themeda triandra (Figure 2-23).

The woody layer consists mainly of a few scattered individuals of the dwarf shrubs Protea welwitschii, Lopholaenia coriifolia, and the geoxylophyte Parinari capensis, that are locally prominent. The grasses Alloteropsis semialata, Panicum natalense, Urelytrum agropyroides, Tristachya leucothrix, Monocymbium ceresiiforme, Digitaria monodactyla, Sporobolus pectinatus, Alloteropsis semialata, Bewsia biflora and Elionurus muticus are also abundant together with the forbs Cyanotis speciosa, Bulbostylis burchellii, Senecio venosus, Sphenostylus angustifolia and Pentanissia angustifolia (Coetzee et al. 1995; Bredenkamp & Brown 2003).

Eragrostis plana Moist Grassland (Moist Grassland)

The Eragrostis plana Grassland is well represented occurring mainly in high rainfall parts. This grassland type is a moist grassland, usually restricted to flat plains or bottomlands, mostly on moist, deep, clayey and poorly drained, seasonally wet soils, adjacent to wetlands , seasonal as well as perennial rivers. These habitats are often fairly unstable due to seasonal flooding and drying, which, together with frequent overgrazing, cause degradation of the vegetation (Bezuidenhout & Bredenkamp 1990).

Eragrostis plana is conspicuous, often dominant member of this grassland type (Figure 2-24). Paspalum dilatatum, and the rhizomatous Cynodon dactylon, often presents in degraded sites, are also diagnostic, as well as the forbs Crabbea acaulis, Berkheya radula, B. pinnatifida and Trifolium africanum. Grass species such as Eragrostis curvula, Themeda triandra, Setaria sphacelata and Digitaria eriantha are often abundantly present, and may be locally dominant, while forbs are generally quite rare (Coetzee et al. 1995; Bredenkamp & Brown 2003).

Seepage areas and wetland communities

Seepage areas are seasonally wet areas that occur in sandy areas where water seeps into lowlying drainage lines after rains. These areas are usually covered by hygrophytes such as sedges and reeds. The dominant sedge in the study area is Juncus rigidus. Sometimes bulrush (Typha capensis) and reeds (Phragmites australis) also occur.

Wetlands are of a more permanent nature and occur in low-lying areas such as tributaries of streams and rivers. Here hydrophytes can be found. Typical plants are the Orange River Lily (Crinum bulbispermum), bulrush (Typha capensis) and reeds (Phragmites australis), sedges of the Cyperus, Fuirena and Scirpus genera also occur (Figure 2-25).

Red data Flora Species

The findings of the ecological assessment undertaken for the New Largo Coal Mine identified Frithia humulis on rocky outcrops just south of the proposed routes. None of the proposed power line alternatives traverses over this area, however they all are very close in proximity, and a no-go buffer was placed around the red data sites as shown in the Figure. These findings were confirmed by the South African National Biodiversity Institute during a site visit to the area, and a 100m buffer was proposed.

Table 2-9 below illustrates the potential red data species that could occur in the area, according to the red data species database from the Mpumalanga environmental department.

Methodology

This section was adapted from the Golder report “Ecological Follow-up Surveys for the Proposed ESKOM Bravo Power Station near Kendal, Mpumalanga, 2008”. In order to enable a characterization of the environment, as well as floral and faunal species that may be impacted by the proposed power line, faunal groups were investigated. The groups of species investigated were:

Arthropoda;

Mammals;

Herpetofauna (Reptiles); and

Amphibia.

Avifauna was excluded as a separate specialist study was conducted for the avi-fauna. Methods implemented during this investigation are based on accepted scientific investigative techniques and principles and were performed to acceptable standards and norms, taking the limitations of this investigation into consideration. The Precautionary Principle was applied throughout the assessments.

Arthropoda

Arthropods were surveyed by means of setting out of pitfall traps, in selected areas within the various vegetation communities, and intensive transects making use of visual identification. Furthermore capture of species on the wing was also undertaken in order to aid identification, this was done by means of sweep-netting. Identification of species was done to the lowest possible taxonomic level using Picker et al (2002).

Suitable habitat was identified for scorpions, spiders and butterflies in order to select areas in which to sample by means of pitfall traps and visual identification, as well as to determine the possibility of the occurrences of Red Data or protected species of these taxa.

Reptilia

Suitable areas were identified and sampled using active search and capture methods, searches were concentrated in rocky areas and disused ant hills were investigated for the presence of snakes. Snakes and other reptiles are identified visually and only captured if visual identification is hampered by swift-moving snakes or if the snake is obscured from view. Branch, 1996 was used as an identification guide, where necessary.

Amphibia

Suitable areas for frogs were sampled by means of active search and capture and acoustic identification methods, especially at night when highest amphibian activity is expected. Areas were also netted for tadpoles and amphibian species identified by means of tadpoles. Carruthers (2001) was used to confirm identification where necessary.

Mammalia

Sherman traps were placed at the sites during the night in order to capture small mammals. Visual sightings and ecological indications were used to identify the small mammal inhabitants of the

study area. Scats were also collected and used for identification of nocturnal small mammals. Stuart and Stuart (1993) and Smithers (1992) were used for identification purposes.

Red Data Faunal Assessment

The following parameters were used to assess the Probability of Occurrence of each Red Data species:

Habitat requirements (HR) – Most Red Data animals have very specific habitat requirements and the presence of these habitat characteristics in the study area was evaluated.

Habitat status (HS) – The status or ecological condition of available habitat in the area is assessed. Often a high level of habitat degradation prevalent in a specific habitat will negate the potential presence of Red Data species (this is especially evident in wetland habitats).

Habitat linkage (HL) – Movement between areas for breeding and feeding forms an essential part of the existence of many species. Connectivity of the study area to surrounding habitat and the adequacy of these linkages are evaluated for the ecological functioning of Red Data species within the study area.

Probability of occurrence is presented in four categories, namely:

Low;

Medium;

High; and

Recorded.

Arthropoda

A total of 67 arthropods were recorded during the site investigation and are given in Table 2-10. All of the species recorded during the survey were common grassland species and are not restricted in terms of habitat or distribution. It is likely that more species may occur in the area. However it is unlikely that Red Data arthropod species, such as Aloeides dentatis or Aloeides merces, occur on this site as the host plants for these species are not present.

2.7 VISUAL IMPACT ASSESSMENT

2.7.1 Introduction

The site and surrounding area may be characterised as agricultural land utilised mainly for the grazing of cattle, with isolated areas of sand mining, coal mining and brickworks. A recent addition to the area is the construction of the Kusile Power Station. The topography of the region and study site is gently undulating to moderately undulating landscape of the Highveld plateau.

The proposed power lines are located in the area immediately noerth and west of the Kusile Power Station with the power station construction site and other infrastructures like existing power lines and roads featuring prominently in the landscape.

2.7.2 Methodology

The methodology adopted for the visual assessment includes the following tasks:

Examine the baseline information (contours, building dimensions, vegetation);

Determine the area from which the proposed power line may be visible (viewshed);

Identify the locations from which views of the proposed power line may be visible (observation sites), which include buildings and roads;

Analyse the observation sites to determine the potential level of visual impact that may result from the proposed railway; and

Identify measures available to mitigate the potential impacts.

Each component of the assessment process is explained in detail in the following sections of the Report.

ZITHOLELE CONSULTING

The Viewshed

The viewshed represents the area from which the proposed site would potentially be visible. The extent of the viewshed is influenced primarily by the combination of topography and vegetation, which determine the extent to which the site would be visible from surrounding areas.

The viewshed was determined by Zitholele through the following steps and presumptions:

The likely viewshed was determined by desktop study (ArcGIS) using contour plans (20 m interval); and

An offset of 2 m (maximum) for the observer and an offset of 30 m (maximum) for the proposed power lines were utilized during the spatial analysis.

Visibility Assessment

Site visibility is an assessment of the extent to which the proposed power line would potentially be visible from surrounding areas. It takes account of the context of the view, the relative number of viewers, duration of view and view distance.

The underlying rationale for this assessment is that if the proposed power line (and associated infrastructure) is not visible from surrounding areas then the development will not produce a visual impact. On the other hand if one or more power lines are highly visible to a large number of people in surrounding areas then the potential visual impact is likely to be high.

Based on a combination of all these factors an overall rating of visibility was applied to each observation point. For the purpose of this report, categories of visibility have been defined as high (H), moderate (M) or low (L).

Assessment Criteria

For the purpose of this report, the quantitative criteria listed in Table 2-15 have been determined and used in the Visibility Assessment. The criteria are defined in more detail in the subsection following.

Table 2-15: Visual Impact Assessment Criteria

CRITERIA DEFINITIONS Category of Viewer Static Farms, homesteads or industries Dynamic Travelling along road View Elevation Above Higher elevation then proposed power line. Level Level with power line view Below Lower elevation then power line viewed View Distance

March 2011 51 12627

ZITHOLELE CONSULTING

CRITERIA DEFINITIONS Long > 5 km Medium 1 – 5 km Short 200 m – 1 000 m Very Short < 200 m Period of View Long Term > 120 minutes Medium Time 1 – 120 minutes Short Term < 1 minute

Category Viewer

The visibility of the proposed power line will vary between static and dynamic view types. In the case of static views, such as views from a farmhouse or homestead, the visual relationship between the proposed power line and the landscape will not change. The cone of vision is relatively wide and the viewer tends to scan back and forth across the landscape.

In contrast views from a moving vehicle are dynamic as the visual relationship between the proposed power line is constantly changing as well as the visual relationship between the proposed power line and the landscape in which they it is seen. The view cone for motorists, particularly drivers, is generally narrower than for static views.

View Elevation

The elevation of the viewer relative to the object observed significantly influences the visibility of the object by changing the background and therefore the visual contrast. In situations where the viewer is at a higher elevation than the building/structure it will be seen against a background of landscape. The level of visual contrast between the proposed power line and the background will determine the level of visibility. A white/bright coloured structure seen against a background of dark/pale coloured tree-covered slopes will be highly visible compared to a background of light coloured slopes covered by yellow/brown dry vegetation.

In situations where the viewer is located at a lower elevation than the proposed power lines it will mostly be viewed against the sky. The degree of visual contrast between a metallic structure will depend on the colour of the sky. Dark grey clouds will create a significantly greater level of contrast than for a background of white clouds.

View Distance

The influence of distance on visibility results from two factors:

With increasing distance the proportion of the view cone occupied by a visible structure will decline; and

Page 60: DRAFT BIOPHYSICAL REPORT - zitholele - Duvha/3. Environmental... · DRAFT BIOPHYSICAL REPORT March 2011 ... the New Largo Coal Mine adjacent to the Kusile Power ... Duvha-Minerva

March 2011 52 12627

ZITHOLELE CONSULTING

Atmospheric effects due to dust and moisture in the air reduce the visual contrast between the structure and the background against which they are viewed.

Period of View

The visibility of structures will increase with the period over which they are seen. The longer the period of view the higher the level of visibility. However, it is presumed that over an extended period the level of visibility declines as people become accustomed to the new element in the landscape.

Long term views of the proposed power line will generally be associated with farms homesteads located within the viewshed. Short term and moderate term views will generally relate to people moving through the viewshed mostly by vehicle.

Site Visibility

The procedure followed by Zitholele to assess Site Visibility involved:

Generate a viewshed analysis of the area utilizing ArcGIS 9.

Determine the various categories of observation points (e.g. Static, Dynamic).

Impact Assessment Methodology

Visual impact is defined as the significance and/or severity of changes to visual quality of the area resulting from a development or change in land use that may occur in the landscape.

Significance or severity is a measure of the response of viewers to the changes that occur. It represents the interaction between humans and the landscape changes that they observe. The response to visible changes in the landscape may vary significantly between individuals.

Perception results from the combination of the extent to which the proposed power line is visible (level of visibility) and the response of individuals to what they see. A major influence on the perception of people/tourist in relation to the proposed power line will be the visual character and quality of the landscape in which it would be located. Natural landscape areas such as national parks, mountain areas or undeveloped sections of coast are valued for their high visual quality. The introduction of buildings and associated infrastructure may be seen as a negative impact on these areas of high visual quality. In the case of this site many people are used to the power lines as the line is existing and has been in the area for a number of years.

The potential visual impact of the proposed power line will primarily result from changes to the visual character of the area within the viewshed. The nature of these changes will depend on the level of the visual contrast between buildings/structures and the existing landscape within which they would be viewed.

ZITHOLELE CONSULTING

The degree of contrast between the proposed power line and the surrounding landscape will result from one or more of the following visual characteristics:

Colour;

Shape or form;

Scale;

Texture; and

Reflectivity.

2.7.3 Visual Character

Landscape Character

The site and the surrounding area can be described as an agricultural landscape with intermittent mining and power generation activities. The proposed power line will be located on a slope starting at the Klipfonteinspruit valley bottom and moving up the slope towards the Kusile Power Station. Elevations along the slope range from 1 420 mamsl and 1 520 mamsl. All power line route alternatives are located on this slope with very little screening from topography or vegetation. Please refer to Figure 2-1 for the topography of the site.

There are no major rivers in the area, but the non perennial Klipfonteinspruit and an unnamed tributary to the spruit are found on site. Alternative 1 crosses the Klipfonteinspruit and the tributary, while Alternative 2 is aligned along the tributary and crosses the Klipfonteinspruit. For an illustration of the surface water features please refer to Figure 2-15.

The landscape surrounding the proposed power line can be described as open grassland with numerous cultivated fields. In addition a large section of the site is currently being developed for the Kusile Power Station. The natural vegetation does not provide any screening for the proposed power line. There are also several existing power lines on site. Figure 2-26 below provides a view of the existing Duvha-Minerva power line lines looking east along the power line line.

The study area is dominated by agricultural smallholdings and small farms with the main farming activities being either livestock or maize farming. The N4 highway and the R 104 regional roads cross through the site and the power line will cross over/under these roads. In addition to the main roads, several smaller gravel farm roads also occur in the area along with several 400 kV power lines.

Viewshed

It should be noted that the viewshed, which is plotted on Figure 2-27, is an approximation that may vary in some locations. Potential views to the proposed power line are likely to be blocked in some

localised situations by buildings, vegetation or local landform features at specific locations within the viewshed. Similarly, glimpses of the proposed power line may be available from some isolated high-elevation locations outside the plotted viewshed. The figures illustrate the visibility of each of the alternatives. The coloured areas indicate areas that are visible with the red areas having very high visibility and the green having lower visibility. It should be noted that the variations in visual impact between the alternatives are relatively small, considering the alignment of all three alternatives together in the northern part of the route, which is also the most populated.

Figure 2-26: View of the existing power line from the takeoff point looking west.

Notable features of the viewshed are summarised by the following points:

The viewshed extends approximately 6 km to the north of the proposed power line;

In a easterly direction the viewshed is generally limited by a ridgelines approximately 9 km from the site, just before Emalahleni;

To the west the viewshed extends approximately 12 km with isolated views on high outcrops; and

Potential views from the south are blocked by the flowing ridges located south from the proposed site, and the viewshed extends about 8 km.

3 IMPACT ASSESSMENT METHODOLOGY

The impacts will be ranked according to the methodology described below. Where possible, mitigation measures will be provided to manage impacts. In order to ensure uniformity, a standard impact assessment methodology was utilised so that a wide rage of impacts can be compared with each other. The impact assessment methodology makes provision for the assessment of impacts against the following criteria:

Significance;

Spatial scale;

Temporal scale;

Probability; and

Degree of certainty.

A combined quantitative and qualitative methodology was used to describe impacts for each of the aforementioned assessment criteria. A summary of each of the qualitative descriptors along with the equivalent quantitative rating scale for each of the aforementioned criteria is given in Table 3-1.

Table 3-1: Quantitative rating and equivalent descriptors for the impact assessment criteria

Rating Significance Extent Scale Temporal Scale 1 VERY LOW Isolated sites / proposed

site Incidental

2 LOW Study area Short-term 3 MODERATE Local Medium-term 4 HIGH Regional / Provincial Long-term 5 VERY HIGH Global / National Permanent

A more detailed description of each of the assessment criteria is given in the following sections.

3.1 SIGNIFICANCE ASSESSMENT

Significance rating (importance) of the associated impacts embraces the notion of extent and magnitude, but does not always clearly define these since their importance in the rating scale is very relative. For example, the magnitude (i.e. the size) of area affected by atmospheric pollution may be extremely large (1 000 km2) but the significance of this effect is dependent on the concentration or level of pollution. If the concentration is great, the significance of the impact would be HIGH or VERY HIGH, but if it is diluted it would be VERY LOW or LOW. Similarly, if 60 ha of a grassland type are destroyed the impact would be VERY HIGH if only 100 ha of that grassland type were known. The impact would be VERY

ZITHOLELE CONSULTING

LOW if the grassland type was common. A more detailed description of the impact significance rating scale is given in Table 3-2 below.

Table 3-2 : Description of the significance rating scale

Rating Description 5 Very high Of the highest order possible within the bounds of impacts which

could occur. In the case of adverse impacts: there is no possible mitigation and/or remedial activity which could offset the impact. In the case of beneficial impacts, there is no real alternative to achieving this benefit.

4 High Impact is of substantial order within the bounds of impacts, which could occur. In the case of adverse impacts: mitigation and/or remedial activity is feasible but difficult, expensive, time-consuming or some combination of these. In the case of beneficial impacts, other means of achieving this benefit are feasible but they are more difficult, expensive, time-consuming or some combination of these.

3 Moderate Impact is real but not substantial in relation to other impacts, which might take effect within the bounds of those which could occur. In the case of adverse impacts: mitigation and/or remedial activity are both feasible and fairly easily possible. In the case of beneficial impacts: other means of achieving this benefit are about equal in time, cost, effort, etc.

2 Low Impact is of a low order and therefore likely to have little real effect. In the case of adverse impacts: mitigation and/or remedial activity is either easily achieved or little will be required, or both. In the case of beneficial impacts, alternative means for achieving this benefit are likely to be easier, cheaper, more effective, less time consuming, or some combination of these.

1 Very low Impact is negligible within the bounds of impacts which could occur. In the case of adverse impacts, almost no mitigation and/or remedial activity are needed, and any minor steps which might be needed are easy, cheap, and simple. In the case of beneficial impacts, alternative means are almost all likely to be better, in one or a number of ways, than this means of achieving the benefit. Three additional categories must also be used where relevant. They are in addition to the category represented on the scale, and if used, will replace the scale.

0 No impact There is no impact at all - not even a very low impact on a party or system.

3.2 SPATIAL SCALE

The spatial scale refers to the extent of the impact i.e. will the impact be felt at the local, regional, or global scale. The spatial assessment scale is described in more detail in Table 3-3.

Table 3-3 : Description of the significance rating scale

Rating Description 5 Global/National The maximum extent of any impact. 4 Regional/Provincial The spatial scale is moderate within the bounds of impacts

possible, and will be felt at a regional scale (District Municipality to Provincial Level).

3 Local The impact will affect an area up to 5 km from the proposed study area.

2 Study Area The impact will affect an area not exceeding the study area.

1 Isolated Sites / proposed site

The impact will affect an area no bigger than the power line alignments.

3.3 DURATION SCALE

In order to accurately describe the impact it is necessary to understand the duration and persistence of an impact in the environment. The temporal scale is rated according to criteria set out in Table 3-4.

Table 3-4: Description of the temporal rating scale

Rating Description 1 Incidental The impact will be limited to isolated incidences that are

expected to occur very sporadically. 2 Short-term The environmental impact identified will operate for the duration

of the construction phase or a period of less than 5 years, whichever is the greater.

3 Medium term The environmental impact identified will operate for the duration of life of plant.

4 Long term The environmental impact identified will operate beyond the life of operation.

5 Permanent The environmental impact will be permanent.

3.4 DEGREE OF PROBABILITY

Probability or likelihood of an impact occurring will be described as shown in Table 3-5 below.

Page 67: DRAFT BIOPHYSICAL REPORT - zitholele - Duvha/3. Environmental... · DRAFT BIOPHYSICAL REPORT March 2011 ... the New Largo Coal Mine adjacent to the Kusile Power ... Duvha-Minerva

Table 3-5 : Description of the degree of probability of an impact occurring

Rating Description 1 Practically impossible 2 Unlikely 3 Could happen 4 Very Likely 5 It’s going to happen / has occurred

3.5 DEGREE OF CERTAINTY

As with all studies it is not possible to be 100% certain of all facts, and for this reason a standard “degree of certainty” scale is used as discussed in Table 3-6. The level of detail for specialist studies is determined according to the degree of certainty required for decision-making. The impacts are discussed in terms of affected parties or environmental components.

Table 3-6 : Description of the degree of certainty rating scale Rating Description

Definite More than 90% sure of a particular fact. Probable Between 70 and 90% sure of a particular fact, or of the likelihood

of that impact occurring. Possible Between 40 and 70% sure of a particular fact or of the likelihood

of an impact occurring. Unsure Less than 40% sure of a particular fact or the likelihood of an

impact occurring. Can’t know The consultant believes an assessment is not possible even with

additional research. Don’t know The consultant cannot, or is unwilling, to make an assessment

given available information.

3.6 QUANTITATIVE DESCRIPTION OF IMPACTS

To allow for impacts to be described in a quantitative manner in addition to the qualitative description given above, a rating scale of between 1 and 5 was used for each of the assessment criteria. Thus the total value of the impact is described as the function of significance, spatial and temporal scale as described below:

Impact Risk = (SIGNIFICANCE + Spatial + Temporal) X Probability

3 5

An example of how this rating scale is applied is shown below:

Page 68: DRAFT BIOPHYSICAL REPORT - zitholele - Duvha/3. Environmental... · DRAFT BIOPHYSICAL REPORT March 2011 ... the New Largo Coal Mine adjacent to the Kusile Power ... Duvha-Minerva

March 2011 60 12627

ZITHOLELE CONSULTING

Table 3-7 : Example of Rating Scale

Impact Significance Spatial Scale

Temporal Scale

Probability Rating

LOW Local Medium-term Could Happen Impact to air 2 3 3 3 1.6

Note: The significance, spatial and temporal scales are added to give a total of 8, that is divided by 3 to give a criteria rating of

2,67. The probability (3) is divided by 5 to give a probability rating of 0,6. The criteria rating of 2,67 is then multiplied by the

probability rating (0,6) to give the final rating of 1,6.

The impact risk is classified according to five classes as described in the table below.

Table 3-8 : Impact Risk Classes

Rating Impact Class Description 0.1 – 1.0 1 Very Low 1.1 – 2.0 2 Low 2.1 – 3.0 3 Moderate 3.1 – 4.0 4 High 4.1 – 5.0 5 Very High

Therefore with reference to the example used for air quality above, an impact rating of 1.6 will fall in the Impact Class 2, which will be considered to be a low impact.

3.7 CUMULATIVE IMPACTS

It is a requirement that the impact assessments take cognisance of cumulative impacts. In fulfilment of this requirement the impact assessment will take cognisance of any existing impact sustained by the operations, any mitigation measures already in place, any additional impact to environment through continued and proposed future activities, and the residual impact after mitigation measures.

It is important to note that cumulative impacts at the national or provincial level will not be considered in this assessment, as the total quantification of external companies on resources is not possible at the project level due to the lack of information and research documenting the effects of existing activities. Such cumulative impacts that may occur across industry boundaries can also only be effectively addressed at Provincial and National Government levels.

Using the criteria as described above an example of how the cumulative impact assessment will be done is shown below:

Impact Significance Spatial Scale

Temporal Scale

Probability Rating

Initial / Existing Impact (I-IA)

2 2 2 1 0.4

Additional Impact (A-IA) 1 2 1 1 0.3

ZITHOLELE CONSULTING

Impact Significance Spatial Scale

Temporal Scale

Probability Rating

Cumulative Impact (C-IA) 3 4 2 1 0.6 Residual Impact after mitigation (R-IA)

2 1 2 1 0.3

As indicated in the example above the Additional Impact Assessment (A-IA) is the amount that the impact assessment for each criterion will increase. Thus if the initial impact will not increase, as shown for temporal scale in the example above the A-IA will be 0, however, where the impact will increase by two orders of magnitude from 2 to 4 as in the spatial scale the A-IA is 2. The Cumulative Impact Assessment (C-IA) is thus the sum of the Initial Impact Assessment (I-IA) and the A-IA for each of the assessment criteria.

In both cases the I-IA and A-IA are assessed without taking into account any form of mitigation measures. As such the C-IA is also a worst case scenario assessment where no mitigation measures have been implemented. Thus a Residual Impact Assessment (R-IA) is also made which takes into account the C-IA with mitigation measures. The latter is the most probable case scenario, and for the purpose of this report is considered to be the final state Impact Assessment.

3.8 NOTATION OF IMPACTS

4 IMPACT ASSESSMENT

The Impact Assessment will highlight and describe the impact to the environment following the abovementioned methodology and will assess the following components:

Soils and Agricultural Potential

Surface Water and Wetlands;

Terrestrial Ecology, and

Visual Assessment.

The impact assessment was undertaken for the construction and operational phases of the project. The impact of each line/route alternative was also assessed separately, however, where the impact was not significantly different, only one impact assessment was undertaken. The power line will constitute a single 400 kV power line with a single overhead line and an access road (Figure 4-1). According to the design team the impact servitude required for such a power line would be approximitaly 55 m.

Figure 4-1: Example of what the power line would look like

March 2011 63 12627

ZITHOLELE CONSULTING

4.1 SOILS AND AGRICULTURAL POTENTIAL

4.1.1 Initial Impact

As mentioned above, the site will soon be the New Largo Coal Mine. The section of soils that will be crossed by the power line alternatives are presently not impacted by the construction of the mine, but in the near future the construction of the mine could start. In addition there are several sand mining, brickworks and coal mining operations present in the area. Other existing impacts are the existing power line pylon footings (132 kV) and cultivation of soils for mainly maize and fodder.

The soils that are mined or part of a mining operation could be removed in entirety or become sterile from being stored in stockpiles and could not be used for the land capability that the soils possess. This impact is rated as a HIGH negative impact that occurs on isolated sites and will remain for the long term. The impact is very likely to occur and is therefore rated as a High impact.

4.1.2 Additional Impact

During the construction phase, the 400 kV power lines will be erected. A 400 kV Transmission line requires a servitude width of 55 m. Where there are physical constraints such as other power lines adjacent to the new servitude, a minimum of 55 m-separation distance from such lines is required. The power line cables are strung between pylons / towers, which are steel structures erected on concrete footings fixed in the substrate (soil or rock) below the pylon.

The major impacts during construction are the construction activities associated with the erection of the power lines and include, amongst others, excavation of the pylon footings, heavy vehicle movement, construction of an access road and waste generation.

The impact to soils and land capability will be the removal of the soil resource at the pylon footings by means of excavation, possible contamination and pollution of the soil from heavy vehicle movement and the compaction of the soils from heavy vehicle traffic. Another potential impact to soils is during the construction of an access road to the pylons the cleared road could become prone to erosion, and thereby removing the soil resource. Due to the fact that the various alternatives are some similar in length and traverse the same areas the impact is rated as identical for all the alternatives.

Considering the potential impact described above the additional impact during construction is rated as a LOW negative impact occurring in the study area and acting in the short-term. This impact will likely occur and as such is rated as a Low impact.

During the operational phase the pylon footings will remain, but the vehicle traffic will significantly reduce. The impact is rated as a LOW negative impact occurring in the study

ZITHOLELE CONSULTING

area and acting in the long-term. This impact could occur and as such is rated as a Low impact.

The ratings of the impacts are shown in Table 4-1 below.

4.1.3 Cumulative Impact

The cumulative impact during the construction phase remains as assessed above in the initial assessment as the impact stretches over the study site. Therefore the impact remains a Moderate impact.

4.1.4 Mitigation Measures

Avoid unnessacary removal of vegetation cover;

If possible utilise the existing servitude road that was constructed for the 132 kV power line to Kusile;

Ensure that all machinery on site is in a good working order;

Limit all activities to the proposed power line servitude;

Ensure that adequate storm water control measures are in place to prevent erosion;

Avoid placement of pylons on the clay soils;

Spread absorbent sand on areas where oil spills are likely to occur, such as the refuelling area in the hard park;

Oil-contaminated soils are to be removed to a contained storage area and bio-remediated or disposed of at a licensed facility;

If soils are excavated for the foundations construction, ensure that the soil is utilised elsewhere for rehabilitation/road building/fill purposes; and

Ensure that soil is stockpiled in such a way as to prevent erosion from storm water.

4.1.5 Residual Impact

The residual impact with the successful implementation of the mitigation measures mentioned above will be slightly less significant as the probability reduces slightly. The result is a MODERATE impact in the study site in the Long Term. This impact is very likely to occur and the rating remains Moderate. This is relevant for both the construction and operational phases.

4.2 SURFACE WATER AND WETLANDS

4.2.1 Initial Impact

The initial impacts on surface water and wetlands are mostly located around the Kusile power station and a few new roads that are being built in the area. In terms of older impacts a number of farm dams have been constructed in the water courses, but this appears not to have affected the downstream aquatic environment.

The site is currently undergoing major construction works with the potential to contaminate the surface water through hydrocarbon and dust pollution, and furthermore the proposed mining activitities from New Largo could add to this impact. In addition the study area is criss-crossed with roads and their associated bridges over the rivers and streams. This existing impact is a HIGH impact acting on isolated sites in the Long Term. This impact is ocuring and is rated as a Moderate impact as shown in Table 4-2 below.

4.2.2 Additional Impact

The potential impact from the construction of the power line through surface water and wetland areas could alter the environment if a pylon is placed inside the wetland or surface water body. This alteration will occur from firstly the excavation of the soil, which will increase the turbidity in the water. Secondly the heavy vehicles that are required to erect the pylons will also drive through the wetland/surface water area that will mobilise sediment increasing turbidity and there is always the risk of hydrocarbon spillages from the vehicles, resulting in pollution of the water. In order for the vehicles to get to the pylons a road will have to be constructed which in turn will require in importation of gravel and the compaction thereof. This will alter the stream flow environment and impact on the vegetation in the wetland.

Due to the fact that the alternatives all cross the same rivers, wetlands and drainage features, there is no discernable difference in the impact of the various alternatives. This

ZITHOLELE CONSULTING

potential impact is rated as VERY HIGH impact acting on isolated sites in the short term. This impact is very likely to occur and is rated as a Moderate impact.

During the operational phase the structures constructed will remain on site and have the potential to continue impacting on the water resource. During operations the potential impacts are the reduction or altering of the stream flow by the physical structure in the water. This impact is rated as a HIGH impact acting on isolated sites in the Long term. This impact is very likely to occur and is rated as a Moderate impact as shown in Table 4-2.

4.2.3 Cumulative Impact

The cumulative impact of the proposed power line along with the existing impacts in the area will cumulatively remain a Moderate impact as rated for the initial impact and shown in the table below.

4.2.4 Mitigation Measures

No construction vehicles or activities will be allowed to work within 50 m from the edge of any of the streams or wetlands on site, unless this cannot be avoided, then it should only occur under supervision of the ECO;

Place pylons outside of the 50 m buffer zone from the edge of the wetlands and riparian zones;

Demarcated areas where waste can be safely contained and stored on a temporary basis during the construction phase should be provided at the hard park;

When adequate volumes (not more than 1 month) have accumulated all waste is to be removed from site and disposed of at a licensed facility;

Waste is not to be buried on site;

Hydro-carbons should be stored in a bunded storage area;

All hazardous materials inter alia paints, turpentine and thinners must be stored appropriately to prevent these contaminants from entering the environment;

Spill-sorb or similar type product must be used to absorb hydrocarbon spills in the event that such spills should occur;

Undertake construction during the dry months to ease the river crossings;

Care must be taken to ensure that in removing vegetation adequate erosion control measures are implemented;

Demarcate the no-go areas with tape and ensure that the demarcation remains in place for the duration of the construction works; and

Use existing river crossings where possible.

4.2.5 Residual Impact

The residual impact if the above mitigation measures are implemented, especially the adherence to the buffer zones could reduce the impact significance and also the probability of the impact. If successfully implemented the impact could be reduced to a LOW impact acting on isolated sites in the short term. This impact could occur and is rated as a Very Low impact during the construction and operational phases.

4.3 TERRESTRIAL ECOLOGY

4.3.1 Initial Impact

The initial impact on the terrestrial ecology of the study is mainly in the form of the agricultural establishment over an extended period of time. The natural grasslands have been transformed into croplands where the soils are left fallow and the remainder of the habitat is used for the grazing of livestock. In addition several alien invasive plants have also established themselves in the area, especially Acacia mearnsii (Black Wattle) and poplar. The natural grasslands have also been fragmented through the establishment of farms, fences and roads in the area. There are patches of grassland that is still in relatively good condition and that support small faunal species, but no large fauna remain in the area.

The highveld grassland habitat which this area falls under has been severely impacted upon by coal mining, sand quarrying and industries such as steel smelters and power stations. These mining and industrial activities not only remove the natural vegetation but insufficient rehabilitation has allowed the spread of invasive species. This is rated as a HIGH impact acting in the long term on the local area. This impact has occurred and is rated as a High impact as shown in Table 4-3 below.

March 2011 68 12627

ZITHOLELE CONSULTING

4.3.2 Additional Impact

The additional impact of the construction and operation of the power line will further fragment an already disturbed ecosystem. During construction the 55 m servitude will be cleared of vegetation that poses a fire or electrical shortage risk. In addition an access road will be constructed as well and the habitat will be lost. This impact is rated as a HIGH impact acting in the short term on the study area. This impact is very likely to occur and is rated as a Moderate impact. During the operational phase the impacts from construction will persist resulting in a HIGH impact acting in the long term on the study area. This impact is very likely to occur and therefore remains a Moderate impact as assessed below in Table 4-3.

4.3.3 Cumulative Impact

The cumulative impact of both the historical impacts and the proposed development remain as assessed for the initial impact assessment, i.e. a Moderate impact.

4.3.4 Mitigation Measures

Utilise the existing 132 kV power line access road rather than constructing a new road;

Ensure that all gates along the route are closed to avoid farm animals escaping or being stolen;

Do not remove/flatten any fences without prior permission from the local landowner;

All offcut and waste material that is generated during power line construction to be removed from the construction site on a weekly basis;

The contractor must provide waste bags for workers to dispose of their domestic waste and remove the waste off site and dispose at a licensed facility;

No shooting or hunting of animals will be allowed on site;

No cooking fires shall be allowed on site;

Toilet facilities must be provided to workers at their accommodation;

All construction areas should be demarcated prior to construction to ensure that the footprint of the impacts are limited (including areas where vehicles may traverse);

The sensitive vegetation should be avoided and construction limited to 100 m from the edge of the red data plant populations;

Adhere to the ESKOM vegetation management guideline;

All alien invasive species on site should be removed and follow up monitoring and removal programmes should be initiated once construction is complete; and

Install power lines according to the ESKOM bird collision prevention guideline.

4.3.5 Residual Impact

With the successful implementation of the above mitigation measures the impact to the terrestrial ecology can be mitigated to MODERATE impact acting in the long term on the study area. This impact is very likely to occur and is rated as a moderate impact. This is also relevant for the operational phase.

4.4 VISUAL IMPACT ASSESSMENT

The visual simulations prepared by Zitholele Consulting illustrate the extent to which the power line will be visible from key observation points (static and dynamic views). The vertical form/dimensions of the buildings/structures would be hidden by their location among existing buildings and within a well vegetated area. The visual contrast is increased by the “shape” and scale of the buildings/structures, which generally will not be viewed along the skyline.

4.4.1 Initial Impact

The existing visual environment in this area has been altered for an extended period of time. Visual impacts include the roads (N4, R545), power lines (Duvha Minerva 400 kV, 2 x 132 kV), industries (Brickworks, Highveld Steel, Kusile Power Station, Kendal Power Station) and mines (Honingkrans Sand, New Largo) in a landscape of predominantly grazing and farming land. This impact is rated as a HIGH impact acting in the local area in the long term. This impact is occurring and is therefore rated as a High impact.

4.4.2 Additional Impact

The additional impact determination for visual aspects is quite a challenge as there are different viewers all over the viewshed. They are classified as either static or dynamic viewers, each of which is described below.

Static Views

The proposed power line would potentially be visible from the surrounding farmland and the high-lying areas to the west of Emalahleni. The potential number of viewers from this area should be low as the farmlands are quite sparsely populated but the views would vary greatly depending on site specific conditions like the orientation of the homes as well as the location of other buildings, fences, vegetation and localized landforms. All these elements have the potential to block views from the buildings to the proposed power line. In addition the existing 400 kV Duvha-Minerva power line traverses in the same vicinity and this existing impact will merely be moved.

Dynamic Views

The power lines will be visible to a moderate number of viewers, mainly those travelling along the N4 highway and some travellers along the R 545. Views from the N4 extend approximately 10 km and represent a view period of approximately 36 seconds travelling at 120 km/h. The level of visibility would be low due to the view distance of more than 5 km and the resulting atmospheric effects that reduce the contrast between the power lines and the surrounding landscape. The effects are similar for the R 545. Please refer to Table 4-4 for a summary of the dynamic impacts. This assessment is similar for all route alternatives.

The proposed power line would also be visible from several farm roads which are located around the proposed site. The viewing distance varies between 1 and 11 km for these roads and if the viewing distance is less than 2 km, the potential visual impact would be considered as moderate.

From the table above it can be concluded that the impact to the visual environment during construction will be a LOW impact acting in the short term on the local area. This impact will occur and is rated as a Moderate impact.

During the operational phase the impacts will remain, and although a static viewer can grow accustomed to a visual impact, the static viewers will not. This impact is rated as a LOW impact acting in the long term on the local area. This impact will occur and is rated as a Moderate impact.

4.4.3 Cumulative Impact

The cumulative impact remains as assessed for the initial impact, i.e. a High impact.

4.4.4 Mitigation Measures

Avoid leaving any building material or waste on site that could create a visual impact;

Only the servitude of the proposed power line should be exposed. In all other areas, the natural vegetation should be retained;

Access road construction should be minimised to prevent unnecessary dust, i.e. use existing roads as far as possible; and

Utilise non-shiny structures for the hard park and toilets, i.e. avoid unpainted roofs.

4.4.5 Residual Impact

With the implementation of the mitigation measures above, the visual impact will be managed as best it could, however in the main the impact will remain as assessed for the additional impact i.e. a Moderate impact for both the construction and operational phases.

The visual impact of the power line in a landscape characterised by existing power lines, roads, power stations, mining and farmlands will have an impact, but not as high as in an unimpacted area. As mentioned before, this is an existing power line that will be moved and therefore the existing impact will simply change location. All four alternatives have very similar visual impacts, however due to Alternative 4’s close proximity to the N4 highway, it is not a recommended route.

5 CONCLUSION

In conclusion the proponent proposes to construct and operate a 400 kV power line in order to deviate the existing Duvha-Minerva power line around the proposed mining area of the New Largo Coal Mine.

Zitholele Consulting was appointed to assess the biophysical aspects and stakeholder sensitivities of the proposed routes. The aspects investigated include topography, soils, agricultural potential, surface water and wetlands, terrestrial ecology and visual impacts.

It was found that the major areas of concern were the red data plant species on site, surface water/wetland crossings, habitat fragmentation and loss of agricultural land.

The alternatives are so close to one another the there is no real grounds for choosing a preferred route, as the impacts are almost identical. However as this report should highlight a preferred option it is the opinion of the specialist that Alternatives 1 and 4 should not be utilised due to their higher visibility and location much closer to the mining area. There is an existing 132 kV power line along a similar alignment to Alternatives 2 and 3, and hence there is also an existing servitude road that can be used. In the view of aligning existing services, Alternative 2 or 3 should be considered.

In the view of the findings represented in this report, it is recommended that the power line deviation be approved conditional to the adherence to the mitigation measures proposed.
