SECTION A: ACTIVITY INFORMATION 1. PROJECT DESCRIPTION

Introduction

The South African National Biodiversity Institute (SANBI) has proposed the development of a new office block, immediately adjacent to their existing Environmental Education Centre, within the Pretoria National Botanical Garden (NBG), situated within the City of Tshwane Metropolitan Municipality. The development is aimed at addressing the needs of SANBI in terms of expanded administrative, research, educational and tourism activities and will be known as the Collections Facility Hub. The proposed development of the Collections Facility Hub (CFH), associated structures and supporting service infrastructure, requires that an Environmental Authorisation (EA) be applied for in terms of the National Environmental Management Act (NEMA) (Act No. 107 of 1998, as amended). CES have been appointed by SANBI to undertake the Basic Assessment (BA) process required in terms of NEMA and the Environmental Impact Assessment (EIA) Regulations (2014, as amended in 2017), for the proposed development. Project Location

The proposed site for this development is situated in the suburb of Silverton, Pretoria, within Region 6 of the City of Tshwane Metropolitan Municipality. The Pretoria NBG is 76 hectares in size (Vibescout, 2018) and is divided into two areas by a central ridge comprised of a quartzite rock formation. The garden is home to the headquarters of SANBI within which their offices are housed. The proposed project will be approximately 0.1 ha and is located directly adjacent the existing Environmental Education (EE) Centre, currently located within the office complex zone of the Pretoria NBG. The office complex area can be accessed via Cussonia Avenue (Figure 1.1) and then via the existing traffic circle and access road which runs parallel to Cussonia Avenue. Thereafter, an existing access control point allows for entrance into the office complex. The proposed CFH will be located immediately east of that access control point. Figure 1.1 and 1.2 below indicates the footprint of the proposed structure, in relation to the existing infrastructure on site. Figure 1.3 further shows the project in the broader context of the Pretoria NBG and surrounding streets.

Project Description and Scope The project construction entails the development of a new 427m² office and exhibition centre, i.e. the CFH and will include:

A steel framed structure with a corrugated roof;

A combination of shop fronts;

Brick and mortar walls, with face brick and plaster and paint finish;

Vinyl floor finishes to all the spaces;

Bathroom;

Reception area; and

Paved walkway leading to the building from both sides (the walkway will be approximately 130m long and between 2m and 10m wide) and will approximately 600m2 to the development footprint.

The building comprises:

78m² of exhibition space ; and

136m² of office space. The following order of works will be required to develop the building: i. Clearing and grubbing; ii. Minor excavations (for foundations);


6

iii. Foundation and concrete pouring; iv. Installing of utilities, connecting sewers, electrical and water to the municipal mains; v. Framing: Sheathing, roof, stairs, windows; vi. Cladding and outer surfaces; vii. Final finishes and internal plumbing. Support Facilities The proposed development is located on Koedoespoort 325 Portion 97, which is managed by the applicant (SANBI) and will make use of existing infrastructure, such as the sewage connection, water connection, electricity and existing roads, currently used to service the existing building and developments already situated within the property. Access Road – The site will be accessed via the National Route 4 (N4) highway from the south or via the R104 regional road from the north and then via Cussonia Avenue (M16). The proposed development site will be accessed via the existing internal access roads currently located within the Pretoria NBG and therefore new access roads will not be required. However, the proposed development will consist of a new paved walkway which will be approximately 10m wide (at its widest point) and approximately 130m in length. Site Camp – An area that was used as a site camp during previous construction activities will be used for this development as it was previously cleared and thus already impacted. The site camp site is accessible via existing access roads, and located north-west of the proposed site (Figure 1.4 and Plate 1.1 below). Materials will be moved to the proposed building site with tipper trucks, over a relatively short distance of 60m.

Plate 1.1. View of the inside of the existing site camp, facing the camp entrance. Water Supply – Water will be required during the construction and operational phases of the proposed development and will be sourced from an existing municipal connection. Approximately 60 000 litres of water will be required for the proposed six (6) month construction period. Approximately 180 000 litres per year will be required for the operational phase. Solid Waste, Wastewater and Sewage – The construction phase of the proposed development will include temporary onsite ablution facilities which will be emptied and serviced by an external service provider. Such ablution facilities are already available at the proposed site camp. Solid waste generated will be collected and stored in a designated area within the site camp and will be removed to a licenced landfill facility by the contractor or an external service provider on a regular basis. During the operational phase, wastewater and sewage will feed into the existing municipal sewer system currently connected to the Pretoria NBG. Solid waste will be removed via municipal collection currently servicing the site on a weekly basis.

2. FEASIBLE AND REASONABLE ALTERNATIVES “alternatives”, in relation to a proposed activity, means different means of meeting the general purpose and requirements of the activity, which may include alternatives to— (a) the property on which or location where it is proposed to undertake the activity; (b) the type of activity to be undertaken; (c) the design or layout of the activity; (d) the technology to be used in the activity;

https://e-gis002.tshwane.gov.za/E_GIS_Web/





9

(e) the operational aspects of the activity; and (f) the option of not implementing the activity.

The preferred alternative considered in this Basic Assessment involves the development of a new building (the proposed CFH) and associated infrastructure (new paved walkway). Only the preferred alternative will be assessed in this report as this alternative is the only reasonable and feasible means of meeting the requirements of the proposed development.

a) Site alternatives

Alternative 1 (preferred alternative)

Description Centre Coordinates

Lat (DDMMSS) Long (DDMMSS) The development of a new building (the proposed CFH) and associated infrastructure (new paved walkway).

25° 44' 22.0" S 28° 16' 35.2" E

No site alternatives are deemed feasible for this particular project due to the positioning of the existing parking lot and EE centre. The preferred site alternative will be the only reasonable and feasible position for the proposed CFH and associated infrastructure (new paved walkway).

b) Lay-out alternatives

Alternative 1 (preferred alternative) Please refer to Appendix C for the preferred layout of the proposed activity. No layout alternatives have been proposed for this development. The preferred layout alternative satisfies the requirements of the applicant in terms of the development of a new building (the proposed CFH) and associated infrastructure (new paved walkway).

c) Technology alternatives

Alternative 1 (preferred alternative) As the activity is related to the development of a new building (the proposed CFH) and associated infrastructure (new paved walkway), the most appropriate construction methods will be used based on what is available in terms of equipment as well as materials. Where possible and practical, standard practices regarding energy efficiency during the construction and operational phases will be followed (i.e. recycling of waste, re-use of materials, energy-saving technology etc.). There are no other technology alternatives proposed for this project as the preferred technology alternative is the only means of achieving the desired outcomes of the project and most feasible and practical options were chosen from an economical and environmental perspective.

d) Other alternatives (e.g. scheduling, demand, input, scale and design alternatives)

There are no other alternatives relevant to this project as the preferred alternative is the only means of achieving the desired development.


10

e) No-go alternative

This alternative assumes that the status quo will remain unchanged and that there will be no new CFH building. Under the No-go alternative, the land will remain vegetated with the existing species most of which were deemed to be of Least Concern in terms of the SANBI Red Data species list. Evidence was observed on site of historical impact, which was also verbally confirmed by the SANBI staff. The area had historically been used as a storage area for construction material, during the construction of the adjacent EE centre. This resulted in the introduction of a few alien invasive species, as well as the disturbance caused by trucks going in and out of the area, and the construction rubble dumping on site, some of which is still seen to this day. Implementation of the ‘No-go’ alternative will result in potential further encroachment of alien vegetation and no CFH building will be developed. This will result in the loss of allocated funds currently provided by DEA and DST to SANBI for new buildings at the Pretoria NBG and will fail to meet the needs of SANBI from administrative, research, educational and tourism perspectives. The employment opportunities associated with the construction phase (approximately 120 temporary opportunities) as well as the operational phase (5 permanent opportunities) of the proposed development will also be lost if the ‘No-go’ alternative is applied.

3. PHYSICAL SIZE OF THE ACTIVITY a) Physical size of the preferred activity/technology as well as alternative

activities/technologies (footprints): Alternative: Size of the activity:

Alternative 1 (preferred activity alternative) Approximately 1000m2

b) Size of the alternative sites or servitudes (within which the above footprints will occur): Alternative: Size of the site/servitude:

Alternative 1 (preferred activity alternative) Approximately 1000m2

4. SITE ACCESS

The site will be accessed via the National Route 4 (N4) highway from the south or via the R104 regional road from the north and then via Cussonia Avenue (M16). The proposed development site will be accessed via the existing internal access roads currently located within the Pretoria NBG and therefore new access roads will not be required. However, the proposed development will consist of a new paved walkway which will be approximately 10m wide (at its widest point) and approximately 130m in length.

10. ACTIVITY MOTIVATION The following section motivates and explains the need and desirability of the activity (including demand for the activity):

The National Development Plan (NDP) represents a new approach by Government to promote sustainable and inclusive development in South Africa, and involves, amongst others, the following key areas of focus:

Improving education and training;

Creating jobs and livelihoods; and

Expanding infrastructure. The proposed project will contribute in some way to all of these key areas. The City of Tshwane Integrated Development Plan 2011-2016 (IDP, 2011) has identified economic growth, development and job creation as one of its main strategic objectives. One of the key governmental outputs expected of the municipality is to provide for ‘education and skills development infrastructure and facilities in relation to existing educational facilities.’ The City of Tshwane is considered to be a national centre for research and learning and is currently undertaking several projects which invest in economic infrastructure development within the Gauteng Province aimed at creating a ‘smart’ province (IDP, 2011). The proposed development will contribute to these aspects and will also create a number of temporary employment opportunities during the construction phase contributing to the municipal and provincial job-creation objectives. The Pretoria NBG currently combines aspects of a recreational environment with a scientific research centre. The purpose of the proposed CFH is to expand the existing administrative, research, educational and tourism potential of SANBI. This will supplement the existing EE centre in terms of skills development, education and awareness programmes currently aimed at increasing biodiversity knowledge within schools and communities. Moreover, the CFH will act as a central administrative building for the virtual collection of over 30 million preserved plant, animal and fossil specimens from over 40 other organisations throughout the country. This will allow for these collections to be used by scientists and researchers throughout South Africa and abroad. The proposed development will not contravene any Environmental Management Framework (EMF) conditions adopted by the DEA and will not be in contravention of any other plans, frameworks or guidelines as set out by the local government. The proposed


12

development is in line with the key focus areas of the relevant IDPs and will not contravene the current land use planning (Government / Open Space) of the larger Pretoria NBG property.

Tshwane Metropolitan Municipality

12. WASTE, EFFLUENT, EMISSION AND NOISE MANAGEMENT a) Solid waste management

Will the activity produce solid construction waste during the construction/initiation phase?

YES

If YES, what estimated quantity will be produced per month? Approximately 30m3

How will the construction solid waste be disposed of (describe)? Solid waste generated will be collected and stored in a designated area within the site camp and will be removed to a licenced landfill facility by the contractor on a regular basis.

Where will the construction solid waste be disposed of (describe)? The waste will be transported to a nearby permitted landfill site, likely the Mamelodi Waste Disposal Site (DWAF Permit No. B33/2/123/88/P215, issued on 1 February 1996).

Will the activity produce solid waste during its operational phase? YES

Approximately 3m3 of solid waste will be produced on a monthly basis. This will consist of general waste derived from the office staff and shop owners who will be working at the CFH, as well as from the visitors to the CFH.

Can any part of the solid waste be classified as hazardous in terms of the NEM:WA? NO

Is the activity that is being applied for a solid waste handling or treatment facility? NO


15

b) Liquid effluent

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

NO

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

NO

The construction phase of the proposed development will include temporary onsite ablution facilities which will be emptied and serviced by an external service provider. Such ablution facilities are already available at the existing site camp. During the operational phase, wastewater and sewage will feed into the existing municipal sewer system currently connected to the Pretoria NBG.

c) Emissions into the atmosphere

Will the activity release emissions into the atmosphere other that exhaust emissions and dust associated with construction phase activities?

NO

Atmospheric emissions are likely to consist of construction-related dust derived from cleared areas and movement of vehicles on site. The concentration of these emissions will vary, but are unlikely to be significant.

d) Waste permit

Will any aspect of the activity produce waste that will require a waste permit in terms of the NEM:WA?

NO

e) Generation of noise

Will the activity generate noise? YES

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


16

Noise will be generated during the construction phase where machinery required for the construction, as well as construction personnel, will be working within the project area. The following mitigation measures will ensure that noise created during construction is managed adequately:

Ensure that vehicles and equipment used on site are in good working order and are serviced properly;

Limit construction activities to daylight hours (e.g. 6am to 6pm);

Apply applicable municipal by-laws with regards to noise control; and

The staff involved in the construction will not be housed on site and will also be informed as to how they can avoid any unnecessary noise pollution during working hours.

There will also be noise, to a lesser degree, generated during the operational phase of the activity as a result of day-to-day activities taking place at the proposed CFH. Operational phase noise can be mitigated and managed via similar measures:

Operational hours must be limited to daylight hours i.e. 6am to 6pm,

Apply applicable municipal by-laws with regards to noise control.

13. WATER USE The source(s) of water that will be used for the activity:

Municipal Water board Groundwater River, stream, dam or lake

Other The activity will not use water

Water will be required during the construction and operational phase of the proposed development and will be sourced from the existing municipal connection. Approximately 180 000 litres of water will be required for the duration of construction which is estimated to take up to 8 months (i.e. approximately 22 500 litres per month). The water requirements of the operational phase will be significantly less however the exact volumes of water use anticipated for the building cannot be determined at this stage.

Does the activity require a water use authorisation (general authorisation or water use license) from the Department of Water Affairs?

NO

The nearest river, as defined by the National Freshwater Ecosystem Priority Areas (NFEPA) database, is that of the Hartbeespruit River, which is located approximately 1440m west of the Pretoria NBG. Although the proposed development will be constructed within 500m of a wetland identified by NFEPA, the proposed development is separated from the wetland by several roads and office complexes. The proposed development will thus have no direct or significant impact on any rivers, wetlands or other watercourses.

14. ENERGY EFFICIENCY The design measures, if any, which have been taken to ensure that the activity is energy efficient:


17

The materials that will be used have been chosen to take into account the recommendations and importance for efficient energy usage. This includes corrugated roof with a combination of shop fronts along with the brick and mortar walls providing natural heat and light to be correctly utilized. A vinyl flooring finish has also been proposed for use in the CFH which will be easier to clean and thus require less cleaning agents and water. Where possible, energy saving technology (e.g. recycling of waste, re-use of materials etc.) will be used.

How alternative energy sources have been taken into account or been built into the design of the activity, if any:

In addition to this, insulation will be used in the CFH roofing and light-emitting diode (LED) light-bulbs will be used for the building lighting. External lighting and any lighting that will be required along the walkways and parking bays will be energy efficient, low mast and down-cast lighting with intensity.

3. GROUNDWATER, SOIL AND GEOLOGICAL STABILITY OF THE SITE Alternative 1 (Preferred Alternative):

Shallow water table (less than 1.5m deep) YES NO

Dolomite, sinkhole or doline areas NO

Seasonally wet soils (often close to water bodies) YES NO

Unstable rocky slopes or steep slopes with loose soil NO

Dispersive soils (soils that dissolve in water) NO

GEOLOGY AND SOILS The entirety of the project area falls within the Daspoort Subgroup (Figure 2.6), which forms part of the Pretoria Group, within the Transvaal Supergroup. The Daspoort Subgroup is dominated by sandstone and quartzite strata (Bartman, 2014). This geological subgroup occupies an elliptical area stretching from the Botswana border, to the Drakensberg escarpment in the east, with Mokopane being the border in the north, and the southern border being Pretoria. The soils within this group consist of red and yellow, massive or weakly structured soils with low to medium base status as is associated with well-drained Ferralsols, Acrisols and Lixisols and one or more of Regosols, Leptosols, Calcisols and Durisols (SOTER, 2018) (Figure 2.7).

4. GROUNDCOVER

SITE OBSERVATIONS A site visit was conducted on 15 June 2018 to confirm the general condition of the site. A few species were found to correspond to the Mucina and Rutherford description for the vegetation type, however most on-site species were deemed Least Concern in terms of their SANBI Red Data species list. Furthermore, clear evidence was observed on site of historical impact, which was also confirmed by the staff of SANBI verbally. The area had historically been used at least as a storage area for construction material, when the EE centre was initially built in the early 2000s. This caused the introduction of a few alien invasive species, as well as the disturbance caused by trucks going in and out of the area, and the construction rubble dumping on site, some of which is still seen to this day (Plate 2.1 and 2.2). Regardless, the area has been relatively undisturbed and moderately good rehabilitation has occurred. As such, the area is deemed to be moderately sensitive for the purposes of this development proposal. Please refer to Appendix D (Ecological Report) for detailed information.

5. SURFACE WATER

The nearest river, as defined by the National Freshwater Ecosystem Priority Areas (NFEPA) database, is that of the Hartbeespruit River, which is located approximately 1440m west of the Pretoria NBG. Although the proposed development will be constructed within 500m of a wetland identified by NFEPA, the proposed development is separated from the wetland by several roads and office complexes. The proposed development will thus have no direct or significant impact on any rivers, wetlands or other watercourses.

6. LAND USE CHARACTER OF SURROUNDING AREA Land uses and/or prominent features that currently occur within a 500m radius of the site and description of how this influences the application or may be impacted upon by the application:

How the boxes marked with an “N “will impact / be impacted upon by the proposed activity

Major road (4 lanes or more): The proposed development is located approximately 20m, 100m and 400m from Cussonia Ave, the N4 highway and the R101 respectively. These roads will have a positive impact on the development as they will allow for access to the proposed development site. The proposed development may result in additional traffic along these routes both during the construction phase and, to a lesser extent, during the operational phase. However, the volume of traffic potentially derived from the proposed development will be insignificant in comparison with the traffic currently experienced along these routes, especially during peak hours.

The land use surrounding the immediate site is conservation, by virtue of the fact that the proposed project is located within an existing national botanical garden. The land use within the broader context however, is entirely built up urban, as office complexes, residential estates and national highways occur in all directions adjacent to site. Figure 2.1 and 2.2 above illustrate the surrounding land use within the broader region.

The proposed site (including any alternative sites) fall within the following:

Critical Biodiversity Area (as per provincial conservation plan) YES

Core area of a protected area? NO

Buffer area of a protected area? NO

Planned expansion area of an existing protected area? NO

Existing offset area associated with a previous Environmental Authorisation? NO

Buffer area of the SKA? NO

Please refer to Figure 2.8 which shows the critical biodiversity areas relative to the proposed development area.

7. CULTURAL/HISTORICAL FEATURES

Are there any signs of culturally or historically significant elements, as defined in section 2 of the National Heritage Resources Act, 1999, (Act No. 25 of 1999), including Archaeological or paleontological sites, on or close (within 20m) to the site?

NO

Uncertain

There is no likelihood that fossils will be found in the diabase underlying the study site. The likelihood that fossils will be found in the rocks of the adjacent Daspoort Formation is very slim due to the thermal metamorphosis this formation would have experienced during the intrusion of the diabase. No heritage features or indications of the presence of such features were observed within the proposed Pretoria National Botanical Garden Infrastructure Project development site and it might be assumed that, considering the transformed nature of the site, the footprint zone is void of heritage or archaeological remains. As a result, the impact of the proposed development on known heritage resources can be considered to be nil. No further heritage mitigation measures are required provided that no previously undetected surface or subsurface heritage remains are found at any point during site clearing or development. Please refer to Appendix D (Heritage and Palaeontological Reports) for detailed information.

Will any building or structure older than 60 years be affected in any way? NO


28

Is it necessary to apply for a permit in terms of the National Heritage Resources Act, 1999 (Act 25 of 1999)?

NO

8. SOCIO-ECONOMIC CHARACTER a) Local Municipality Level of unemployment:

The unemployment rate in the City of Tshwane Metropolitan Municipality is 24.2% and the youth (ages 15 to 34 years) unemployment rate is 32.6%. There are approximately 1.6 million economically active individuals (i.e. people who are employed or unemployed but looking for work) living within the municipality. Approximately 345 000 of the people are currently unemployed (StatsSA, 2011). According to the City of Tshwane IDP (2011), 18% of people living within the municipality earn less than R1600 per month.

Economic profile of local municipality:

The City of Tshwane contributes approximately 27% to the Gauteng Gross Domestic Product (GDP) and approximately 9% to the national GDP. The municipality’s GDP grew by over 21% from 2009 to 2011 and has been the fastest growing municipality in the country for the period 1997 to 2011. The economy is dominated by service-based industries such as community services, government, financial services and manufacturing. The manufacturing sector, upheld by the automotive industry, is well-established in the municipality. The trade performance of the City of Tshwane is rapidly growing and, in 2011, contributed 22.2% to the nation’s total exports and 15.9% to its total trade (StatsSA, 2011).

Level of education:

Approximately 4.2% of the total population of people aged 20 years or older living in the City of Tshwane Metropolitan Municipality have not received any schooling. 29.2% have some secondary education, 20.2% have completed matric and only 6.1% have some form of higher education (StatsSA, 2011).

VEGETATION

According to Mucina and Rutherford (2012), the vegetation type found on site is that of Marikana Thornveld, of the Savanna Biome (Figure 2.9). Marikana Thornveld occupies the plains from the Rustenburg area in the west, to Marikana and Brits in the north, to Pretoria in the east, ranging in altitude from 1050m – 1450m above mean sea level (Mucina and Rutherford, 2012).

Figure 2.9 Vegetation map of the proposed project area (after Mucina and Rutherford,

2012).


31

Vegetation & Landscape Features The landscape within this vegetation type is dominated by open Vachellia karroo woodland, in valleys separated by slightly undulating plains, and some lowland hills. The composition of shrubs increase where regions are more protected from fire (Mucina and Rutherford, 2012). Please refer to Appendix D (Ecological Report) for detailed information. Geology and Soils This vegetation type occurs predominantly in regions where mafic intrusive rocks of the Rustenburg Layers Suite, of the Bushveld igneous complex occurs. Rocks include gabbro, norite, pyroxenite and anorthosite, along with shales and quartzites of the Pretoria group. Melanic, vertic clay soils dominate with some dystrophic or mesotrophic plinthic catenas and some freely drained, deep soils (Mucina and Rutherford, 2012). Climate Where this vegetation type occurs, the climate is dominated by mainly summer rainfalls, with very dry winters. The mean annual precipitation ranges between 600-700mm, with frequent frost occurrences during the winter months. Temperatures range from 35.5°C and -3.3°C for January and June (hottest and coldest months respectively). HYDROLOGY The nearest NFEPA river to site, is that of the Hartbeespruit River, which lies 1440m to the west of the botanical garden. Due to the distance, this project will not impact on any known river sources. The nearest wetlands to site, occur exactly 380m to the south of the proposed site. These are captured on the NFEPA wetlands database as two seep wetlands, contained within the Persequor office complex, located on Meiring Naude Road (Figure 2.10). The proposed development is highly unlikely to have an impact on those wetlands, due to presence of the N4 highway and Proefplaas interchange, which lies between the Botanical Gardens and the Persequor office complex, thus creating a strong barrier to surface water flow. The N4 along with the steep embankments, which will act as a barrier for surface water flow (and thus highly reduce the potential for contamination and impact from one side of the road to the other), can be seen in Plate 2.3 below.

Plate 2.3: View of the N4 approaching the Proefplaas interchange, which acts as a barrier for surface water flow between the proposed site and the nearest wetlands.

Alternative A (preferred alternative)

Twenty-one (21) impacts have been identified as a result of the preferred and only alternative for the proposed project. This consists of 14 construction phase impacts and 7 operational phase impacts. Without mitigation, there will be 16 negative impacts of moderate significance and 2 negative impacts of low significance. There will also be 3 positive impacts (2 moderate and 1 high). With the implementation of mitigation measures, there will be 16 negative impacts of low significance and 2 negligible impact. There will also be 3 positive impacts of (2 moderate and 1 high) which will result from the development. Although there are a greater number of negative impacts, the significance of the positive impacts outweighs the significance of the negative impacts. This is the only reasonable and feasible alternative considered in this application and, considering the result of the impact assessment, this preferred alternative is recommended.

No-go alternative (compulsory)

This alternative assumes that the status quo will remain unchanged and that there will be no new development. Under the No-go alternative, the property will remain unchanged – mostly undisturbed with some building rubble and alien vegetation species. The No-go alternative will mean that there will be no CFH building will be developed and therefore there will be no exhibition space and no additional educational facilities available for the public. This will also result in a loss of much needed administrative space for SANBI. The No-go alternative will have 10 negative impacts of low significance and 5 negative impacts of moderate significance. There will be no positive impacts associated with the No-go alternative.

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

List of 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:

OPINION OF THE EAP: It is the opinion of the EAP that no fatal flaws are associated with the proposed development and that all impacts can be adequately mitigated to reduce the risk or significance of impacts to an acceptable level. The significance of the benefits associated with the proposed development outweighs the significance of the negative aspects. It is the opinion of the EAP that this Basic Assessment Report contains sufficient information to allow the Department of Environmental Affairs (DEA) to make an informed decision. It is therefore recommended that the application for Environmental Authorisation should be approved on condition that the recommended mitigation measures stated herein are effectively implemented. RECOMMENDATIONS OF THE EAP: All mitigation measures, which have been outlined in this report as well as in the Environmental Management Programme (EMPr), must be fully adhered to. In addition, the following recommendations have been made: Pre-Construction:

The contractor is encouraged to use an existing fully serviced site in an already disturbed area for construction camp purposes.

Construction Phase:

An ECO must be employed to ensure that the construction activities remain within the designated area and that no unauthorised activities occur;

The ECO should submit site audits detailing the applicant’s compliance with the EMPr;

An efficient stormwater management system must be implemented during construction;

Workers must be educated on environmental management aspects. Operational Phase:

Water efficient systems, such as dual-flush toilets and water-efficient taps should be used to use water sparingly;

Waste removal must be properly managed at all times. Please refer to Appendix G for the Environmental Management Programme (EMPr).

Please refer to Appendix H for the relevant curriculum vitae of the EAP and the project participants.

IMPACT ASSESSMENT METHODOLOGY


83

IMPACT ASSESSMENT METHODOLOGY

Methodology for Assessing the Significance of Impacts Although specialists will be given relatively free rein on how they conduct their research and obtain information, they will be required to provide their reports to the EAP in a specific layout and structure, so that a uniform specialist report volume can be produced. To ensure a direct comparison between various specialist studies, a standard rating scale has been defined and will be used to assess and quantify the identified impacts. This is necessary since impacts have a number of parameters that need to be assessed. Four factors need to be considered when assessing the significance of impacts, namely: Relationship of the impact to temporal scales - the temporal scale defines the significance of the impact at various time scales, as an indication of the duration of the impact. Relationship of the impact to spatial scales - the spatial scale defines the physical extent of the impact. The severity of the impact - the severity/beneficial scale is used in order to scientifically evaluate how severe negative impacts would be, or how beneficial positive impacts would be on a particular affected system (for ecological impacts) or a particular affected party. The severity of impacts can be evaluated with and without mitigation in order to demonstrate how serious the impact is when nothing is done about it. The word ‘mitigation’ means not just ‘compensation’, but also the ideas of containment and remedy. For beneficial impacts, optimization means anything that can enhance the benefits. However, mitigation or optimization must be practical, technically feasible and economically viable. The likelihood of the impact occurring - the likelihood of impacts taking place as a result of project actions differs between potential impacts. There is no doubt that some impacts would occur (e.g. loss of vegetation), but other impacts are not as likely to occur (e.g. vehicle accident), and may or may not result from the proposed development. Although some impacts may have a severe effect, the likelihood of them occurring may affect their overall significance. Each criterion is ranked with scores assigned as presented in Table F1 to determine the overall significance of an activity. The criterion is then considered in two categories, viz. effect of the activity and the likelihood of the impact. The total scores recorded for the effect and likelihood are then read off the matrix presented in Table F2, to determine the overall significance of the impact (Table F3). The overall significance is either negative or positive. The environmental significance scale is an attempt to evaluate the importance of a particular impact. This evaluation needs to be undertaken in the relevant context, as an impact can either be ecological or social, or both. The evaluation of the significance of an impact relies heavily on the values of the person making the judgment. For this reason, impacts of especially a social nature need to reflect the values of the affected society. Negative impacts that are ranked as being of “VERY HIGH” and “HIGH” significance will be investigated further to determine how the impact can be minimised or what alternative activities or mitigation measures can be implemented. These impacts may also assist decision makers i.e. lots of HIGH negative impacts may bring about a negative decision. For impacts identified as having a negative impact of “MODERATE” significance, it is standard practice to investigate alternate activities and/or mitigation measures. The most effective and practical mitigations measures will then be proposed. For impacts ranked as “LOW” significance, no investigations or alternatives will be considered. Possible management measures will be investigated to ensure that the impacts remain of low significance.

These impacts will usually result in either a positive or negative medium to long-term effect on the social and/or natural environment.

High A serious impact, if not mitigated, may prevent the implementation of the project (if it is a negative impact). These impacts would be considered by society as constituting a major and usually a long-term change to the (natural &/or social) environment and result in severe effects or beneficial effects.

13-16

Very High A very serious impact which, if negative, may be sufficient by itself to prevent implementation of the project. The impact may result in permanent change. Very often these impacts are unmitigatable and usually result in very severe effects, or very beneficial effects.
