SECTION A: ACTIVITY INFORMATION

Has a specialist been consulted to assist with the completion of this section? YES NO

If YES, please complete the form entitled “Details of specialist and declaration of interest” for the specialist appointed and attach in Appendix I. 1. PROJECT DESCRIPTION a) Describe the project associated with the listed activities applied for

Background Information The Applicant, Transnet Pipelines (TPL), was established in 1965 to address the need for a liquid fuels and gas transportation entity. The liquid fuels pipeline network traverses five (5) provinces, KwaZulu-Natal, Free State, Gauteng, North West and Mpumalanga and includes a section of the liquid fuels pipeline from the O.R. Tambo International Airport in Johannesburg to Waltloo in Pretoria which was constructed in 1973. This section of the pipeline has however been exposed at the stream crossings in the Moreleta Spruit in Pretoria, Tshwane Municipality, due to erosion in those areas. In response to the impact of erosion on the pipeline TPL undertook the construction of gabions to protect the exposed liquid fuels pipeline at the stream crossings. The gabions are located on two sites: Site 1 – located in Moreleta Park adjacent to Garsfontein Road; Site 2 – located between Garsfontein and Pretorius Park adjacent to Garsfontein Road (see Appendix A). Although construction of gabions (the activity) requires approval in terms of the Government Notice Regulation (GNR) No. 544 (activity number 11 and 18) and GNR 546 (activity number 16 (b)) of 2nd August 2010 of the National Environmental Management Act No. 107 of 1998 (NEMA) , work commenced on site prior to obtaining the approval as required in terms of the above mentioned legislation. This was mainly due to the potential risk to infrastructure and human life associated with an exposed petroleum pipe. Also as this activity has the potential to impede the stream bed and flow during and post construction , other applicable legislative requirements include the General Authorisations or Water Use License applications in terms of Section 21 (c) of the National Water Act. TPL has since engaged with the Department of Environmental Affairs (DEA), Department of Water Affairs (DWA), City of Tshwane Nature Conservation and the Gauteng Department of Agriculture and Rural Development (GDARD), to give a detailed account of the need and desirability of the work and to ensure that all requirements are met in terms of the information requested by and placed before the Competent Authority for decision making. An Environmental Management Plan (EMP) including a letter of motivation for the commencement of construction was submitted to the DEA on 15 May 2012, and the EMP was subsequently approved. The DEA however also requested that a formal NEMA Section 24G application form for the rectification of unlawful commencement or continuation of a listed activity be lodged. The Section 24G application form was submitted to the DEA on 13 June 2012 (attached in Appendix E), and the DEA responded in a letter dated 13 August 2012 requesting further information (Appendix E). Transnet Pipelines (TPL) has therefore appointed GIBB (Pty) Ltd (GIBB) as the Environmental Assessment Practitioner (EAP) to undertake the relevant environmental authorisation processes for the Moreleta Spruit Gabions Construction Project.

This Draft Basic Environmental Assessment Report (BAR) has been compiled in support of the application for Environmental Authorisation, as required by the NEMA and associated EIA Regulations. Technical Activity Description: The Construction of Gabions along the Moreleta Spruit During routine maintenance, TPL identified two (2) sites along the Moreleta Spruit where the erosion of the channel bottom and banks has resulted in the exposure of the high pressure petroleum fuel pipeline. The sites are in close proximity to each other (approximately 200m apart). Site 1 The site is located adjacent to the East Side Church, on the northern side of Garsfontein Road in Moreleta Park. Construction activities that already commenced in May 2012 include:

Excavation of a river diversion of the Moreleta Spruit (approximately 20m in length) from its original alignment to an alignment approximately 5m to the West to facilitate construction works. The new channel through which the river is being diverted is approximately 0.6m from natural ground level.

An excavation of approximately 5m x 5m within the initial alignment of the Moreleta Spruit, indicating the start of construction for placement of the founding mater ial for the Reno-mattress (Appendix C).

Importing and offloading of the rock material to be used in the Reno-mattress to be constructed in the original alignment of the Moreleta Spruit.

Excavation of the foundation area for the Reno-mattress.

Stockpiling of excavated soil.

Placement of two portable chemical toilets to the East approximately 50m from the Moreleta Spruit.

Site establishment, including placement of a container, to be used for construction personnel on site, for site meeting and as an on-site office.

Limited vegetation cutting and exotic vegetation clearing.

Construction of Reno-mattress including the laying of the geotextile layer.

Install dewatering points and construct silt traps to filter water prior to it filtering back into the wetland system.

Reinstate wetland including but not limited to the following: o Ensure subsoil is at correct levels as per pre-construction survey; o Ensure adequate topsoil is present; o Establish indigenous vegetation with hydroseeding (if required); and o Ensure Moreleta Spruit runs as per original alignment.

General reinstatement and clean-up, including disposing of waste at the nearest licensed landfill site.

Site 2 The site is located on the southern side of Garsfontein Road, between the suburbs of Pretorius Park and Garsfontein. Physical construction works at the time of submission of the Section 24G application form included the offloading of rock material for the gabions to be constructed at the site to arrest the erosion channel that is exposing the petroleum pipeline. Subsequent work needed includes but is not limited to:

Site establishment.

Vegetation cutting and exotic vegetation clearing.

Stripping and stockpiling of soil material in separate stockpiles (topsoil versus subsoils).

Construction of works access to the working area, which may require the cutting back of the banks of the Moreleta Spruit to allow the placement of the gabions.

Damming up of the upstream section of the Moreleta Spruit just below the Garsfontein Road


6

crossing using sandbags.

Creating an area for 2 bunded 0.10 or 0.15 metres high volume pumps to stand in. these pumps will facilitate the cross-pumping of water from above the works area to a point below the works area to ensure a continuous flow of water, that will be unaffected by the cons truction works. Prior to release, the water will pass through a silt trap that will filter any excess silt. The silt will be disposed of at a licensed landfill site.

Excavation in the Moreleta Spruit river bed to construct the foundation which will support the new gabions.

Construction of the gabions.

Backfilling of the area behind the gabions and compacting.

Reinstating the wetland including but not limited to the following: o Ensure subsoil is at correct levels as per pre-construction survey; o Ensure adequate topsoil is present; o Establish indigenous vegetation with hydroseeding (if required); and o Ensure Moreleta Spruit runs as per original alignment.

General reinstatement and clean-up, including disposing of waste at the nearest licensed landfill site.

Activity Need and Desirability: The Construction of Gabions along the Moreleta Spruit The gabions are required to protect the high pressure petroleum fuel pipeline that was constructed in 1973 in order to ensure its safety and security. Exposure of the pipeline occurred due to channel erosion taking place in the Moreleta Spruit. Development that has taken place in the area post -1973 has led to increased impermeable surfaces which in turn have increased flow and velocity of run-off from storm water entering this river system. This has exacerbated the natural erosive pattern of the watercourse. With the pipeline being exposed (as was the case) it was also susceptible to vandalism and/or damage by rocks, boulders, etc. that have been swept downstream during high rainfall events. Should the pipeline have ruptured as a result of either of the scenarios above, thousands of litres of hydrocarbons (fuel) could potentially have contaminated the water in the river which would have an impact on flora and fauna downstream, as well as any other downstream users of the stream, thus leading to both negative ecological and social impacts. The fuel leakage and spillage would also have resulted in volatile organic carbon emissions to the atmosphere. Thus, it is imperative that th e pipeline remain protected from damage, that the stability of the banks of the Moreleta Spruit be reinstated and that erosion is minimised and further scouring of the river banks prevented.

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; (e) the operational aspects of the activity; and (f) the option of not implementing the activity. Describe alternatives that are considered in this application as required by Regulation 22(2)(h) of GN R.543. Alternatives should include a consideration of all possible means by which the purpose and need of the proposed activity (NOT PROJECT) could be accomplished in the specific instance taking account of the interest of the applicant in the activity. The no-go alternative must in all cases be included in the assessment phase as the baseline against which the impacts of the other alternatives are assessed. The determination of whether site or activity alternatives (including different processes, etc.) or both are appropriate needs to be informed by the specific circumstances of the activity and its environment. Upon receipt of this report, the competent authority may also request the applicant to assess additional alternatives that could possibly accomplish the purpose and need of the proposed activity if it is clear that realistic alternatives have not been considered to a reasonable extent. The identification of alternatives should be in line with the Integrated Environmental Assessment Guideline Series 11, published by the DEA in 2004. Should the alternatives include different locations and lay-outs, the co-ordinates of the different alternatives must be provided. The co-ordinates should be in degrees, minutes and seconds. The projection that must be used in all cases is the WGS84 spheroid in a national or local projection. a) Site alternatives According to the regulations GNR543 27(e), the applicant must identify feasible and reasonable alternatives for the proposed activity. The most feasible alternatives identified for the current activity are justified below: Site alternatives: there are no feasible site alternatives for the construction of the gabions, as the fuel

pipeline is exposed at the two specific sites where the activity has commenced. Attempting to minimize erosion further up- or downstream would not necessarily address the issue of the exposed pipeline and the associated environmental and safety risks.

Layout alternatives: layout alternatives are also limited to the two affected sites of erosion and pipeline exposure, and the layout of the gabions will be limited to ensuring that the pipeline is sufficiently protected.

Design Alternatives: there are no applicable technology alternatives as the gabions have already been

constructed, however there are suggested alternatives in terms of the design of the structures that would enhance their ability to perform the erosion control function as well as protecting the fuel pipeline. Section 6.4 of the wetland assessment report and section 4.3 of the aquatic impact assessment report (Specialist reports attached in Appendix D) indicates that subsequent to construction of the gabions, structural damage already occurred. One of the most frequent causes of failure of these structures is the erosion of the gully banks associated with the hydraulic jump that forms downstream of the toe of the step or chute. It is therefore suggested that the design of the erosion control structures must ensure that the


10

jump remains in the protected reach and does not extend downstream. Such design may include end sills, cut-off sills, stilling basins, stepped gabions etc. Figure 1 indicates a typical stepped gabion structure that can address the issue of erosion at the point of the change in hydraulic head. A Reno-mattress is made of woven mesh and filled with rocks, and is used for river bank and channel erosion control and embankment stability. The wetland impact assessment further indicates that the Reno-mattresses below the gabion at site 1 ends abruptly and are not keyed in, and erosion is already evident. It is therefore suggested that the Reno-mattresses be extended and keyed into the ground, thus reducing the concentration of flow at their edges. The binding of the gabions is done with only single strand wire, which will not be strong enough to withstand high flow situations, resulting in gabion failure. It is suggested that the holding structure be improved to maintain integrity. Erosion evident at site 2 is due to the gabion positioned at a sharp angle to the water flow, which results in a buildup of water at one edge and may lead to gabion failure. Alternatives include rebuilding and redesign of the gabion, or extending the problematic wing back so that water builds up equally on either side of the gabion. The bank stabilizing and downstream Reno-mattresses are too short and not keyed into the soil. It is suggested that these Reno-mattresses be extended and keyed into the ground.

Figure 1: Stepped gabion design to reduce erosion at the toe of the gabion

Implementation alternatives: there are no feasible implementation alternatives as the gabions have already been constructed. It is however suggested that remedial work and alterations be undertaken as soon as possible in order to minimize any long term effects of the gabion design on the river system as follows: Phase 1: this phase should involve the redesign of the gabions with the consultation of a wetland

rehabilitation specialist to ensure that the gabions are designed with minimal impact on the river system. Phase 2: implementation of the suggested improvements Phase 3: monitoring of the installation to ensure effective functioning of the system

The No Go Alternative relates to the proposed gabions not being constructed. As such, the fuel pipeline which is the main concern, will remain exposed and could pose both environmental and safety risks. The preferred and only alternative is detailed in the Table below.

Alternative 3

d) Design alternatives

Alternative 1 (preferred alternative) The design of the erosion control structures must ensure that the jump remains in the protected reach and does not extend downstream. Such design alternatives may include end sills, cut-off sills, stilling basins, stepped gabions etc. (refer to fig. 1) Structural related design alternatives include the packing of the rock material within the gabion, and reinforcing the mesh covering to further strengthen the gabion’s structural integrity.

Alternative 2

Alternative 3

e) No-go alternative

The No Go Alternative relates to the proposed gabions not being constructed. As such, the fuel pipeline which is the main concern, will remain exposed and vulnerable to erosion and could pose both environmental and safety risks. It is important to note that the proposed project was undertaken to protect a fuel pipeline that traverses a number of provinces in the country, and the integrity of this pipeline is therefore of national concern.

FACILITY ILLUSTRATION A detailed illustration of the activity must be provided at a scale of at least 1:200 as Appendix C for activities that include structures. The illustrations must be to scale and must represent a realistic image of the planned activity. The illustration must give a representative view of the activity. 10. ACTIVITY MOTIVATION Motivate and explain the need and desirability of the activity (including demand for the activity):

1. Is the activity permitted in terms of the property’s existing land use rights?

YES NO Please explain

The properties’ land use rights include public open space. The fuel pipeline was constructed in 1973 and Transnet has servitude rights on the property for the pipeline inside this public open space.


15

2. Will the activity be in line with the following?

(a) Provincial Spatial Development Framework (PSDF) YES NO Please explain

The development promotes sustainable development by protecting and supporting the current use of the pipeline infrastructure and protecting the public environment for future generations. The pipeline is a key requirement for the transportation of fuel which serves the South African economy.

(b) Urban edge / Edge of Built environment for the area YES NO Please explain

The proposed development is located within the boundaries of the urban edge.

(c) Integrated Development Plan (IDP) and Spatial Development Framework (SDF) of the Local Municipality (e.g. would the approval of this application compromise the integrity of the existing approved and credible municipal IDP and SDF?).


According to the IDP of the City of Tshwane, the mission of the Municipality is “To sustainably enhance the quality of life of all people in Tshwane through a developmental system of local government and by rendering efficient, effective and affordable services.”

This development and the activity aim to protect the health and safety of its residents by lowering the risk of a leaking/ rupturing of the petroleum fuel pipeline. It also aims to ensure that the integrity of the pipeline is not compromised which will enable the continued supply of petroleum fuel that is necessary for economic functioning.

The area is identified as a key open space linking the Rietvlei Nature Reserve with the Faerie Glen Nature Reserve. The importance of the area also becomes clear when viewed within the context of the planned development intensification of the Menlyn Node and Rubenstein Development Zone amongst others in the area.

The gabion construction will thus provide protection of the pipeline, which if left unprotected could result in significant impacts to the open space as well as to the Faerie Glen Nature Reserve and all fauna and flora supported in these areas. It will also stabilise the river banks from erosion.

Approval of this application would therefore not compromise the integrity of the existing municipal IDP and SDF.

(d) Approved Structure Plan of the Municipality YES NO Please explain

The Tshwane Nature Conservation Section has been engaged on the process, and has requested that an Environmental Authorisation must be obtained from the Department of Environmental Affairs (Attached in Appendix J).


16

(e) An Environmental Management Framework (EMF) adopted by the Department (e.g. Would the approval of this application compromise the integrity of the existing environmental management priorities for the area and if so, can it be justified in terms of sustainability considerations?)


The proposed development would not compromise the integrity of the existing environmental management priorities for the area as the proposed development inherently promotes the sustainability of the Transnet Petroleum fuel pipeline, as well as the safety of nearby residents and protection of the surrounding natural environment. Furthermore the existing priorities such as conservation are not in conflict considering that the development is aimed at ensuring that conservation areas are not compromised by hydrocarbon pollution.

(f) Any other Plans (e.g. Guide Plan) YES NO Please explain

Similar to the SDF, the City of Tshwane Open Space Framework identifies the area as a key corridor for species movement. The construction of the gabions protects the petroleum pipeline from damage and leakage which could have a significant impact on the flora and fauna not only within the corridor system but also to the downstream Faerie Glen Nature Reserve.

3. Is the land use (associated with the activity being applied for) considered within the timeframe intended by the existing approved SDF agreed to by the relevant environmental authority (i.e. is the proposed development in line with the projects and programmes identified as priorities within the credible IDP)?


TPL has existing servitude rights for the maintenance and monitoring of the fuel pipeline (Appendix J).


17

4. Does the community/area need the activity and the associated land use concerned (is it a societal priority)? (This refers to the strategic as well as local level (e.g. development is a national priority, but within a specific local context it could be inappropriate.)


The area in which the pipeline was exposed due to erosion from high water flows occurs within Moreleta Park, is located in close proximity to a community church and other settlements.

The proposed construction of gabions will therefore not only protect the petroleum pipeline from becoming further exposed and leaking fuel into the surrounding natural environment, it will also minimise the associated health and safety risks to humans.

Potential impacts of liquid petroleum (if the potential structural compromise of the pipeline is not addressed through the construction of gabions) on the environment include but are not limited to:

1. The effects of liquid petroleum accidentally released into the natural environment are generally toxic and has carcinogenic (cancer causing) effects on humans and animals.

2. Liquid petroleum is a highly flammable substance, which could lead to fires or explosions if exposed to open flame.

3. Vapours released from petroleum into the atmosphere contain volatile organic compounds, many of which have short- and long-term impacts on human health and the environment due to their toxicity and carcinogenic properties.

The aforementioned impacts may not necessarily be local or immediate, or even quantifiable. However the potential health and safety risks and pollution risks to the environment can be very detrimental and the accidental release of petroleum from a leaking or broken fuel pipeline needs to be avoided. The urgency for Transnet to protect the exposed fuel pipeline can therefore be justified in light of these potential impacts.

5. Are the necessary services with adequate capacity currently available (at the time of application), or must additional capacity be created to cater for the development? (Confirmation by the relevant Municipality in this regard must be attached to the final Basic Assessment Report as Appendix I.)


The proposed facility would be located within the Transnet Pipelines servitude. No additional services would be

required from the municipality.

6. Is this development provided for in the infrastructure planning of the municipality, and if not what will the implication be on the infrastructure planning of the municipality (priority and placement of services and opportunity costs)? (Comment by the relevant Municipality in this regard must be attached to the final Basic Assessment Report as Appendix I.)


The construction of the gabions to protect the exposed pipeline was undertaken as part of an emergency

maintenance. There should however be no impact on the municipal infrastructure planning, as the pipeline has

been in existence since 1973.


18

7. Is this project part of a national programme to address an issue of national concern or importance?


Yes. Sustainable Development is a priority for South Africa and in July 2008, the Cabinet passed the

National Framework for Sustainable Development (NFSD). The NFSD is designed to “initiate a broad

framework for sustainable development in South Africa that can serve as a basis from which to develop

and consolidate a national strategy and action plan”. The NFSD proposes a national vision, principles,

trends, strategic priority areas, and a set of implementation measures that are intended to enable and

guide the development of the national strategy and action plan.

The NFSD discusses the various environmental and social risk areas facing South Africa and maps out

five strategic priority areas.

1. Enhancing systems for integrated planning and implementation.

2. Sustaining our ecosystems and using resources sustainably.

3. Investing in sustainable economic development and infrastructure.

4. Creating sustainable human settlements.

5. Responding appropriately to emerging human development, economic and environmental challenges.

This proposed development falls directly in line with the point two and three above. By protecting the

exposed petroleum pipeline, Transnet has ensured that the fuel resources would not be compromised in

any way, thus securing the supply of fuel to the various end users.

The South African Designated National Authority (DNA) further evaluates sustainability in three categories:

Economic, environmental and social. The contribution of the project towards sustainable development is

discussed in terms of these three categories:

Economic: The project will ensure the continued and smooth functioning of fuel supply to other

businesses and end users thus supporting economic operations.

Environmental: At a regional level, the project will have a positive impact on the environment. This

positive impact relates to a reduction in the potential of fuel leakage into the receiving wetland

environment and its associated environmental impacts. As a result the project would reduce the

possibility of water pollution, as well as to mitigate against erosion of the river banks and promote the

conservation of the wetland system, if the proposed design improvements are effected.

Social: The project will contribute to ensuring the safety and health of the nearby residents and

community.

8. Do location factors favour this land use (associated with the activity applied for) at this place? (This relates to the contextualisation of the proposed land use on this site within its broader context.)


The proposed development and activity is located within the existing Transnet Pipeline servitude (refer to

Appendix I for the servitude registration)

9. Is the development the best practicable environmental option for this land/site?


The preferred option to construct erosion control gabions is the best practicable environmental option as

the area the two sites where the fuel pipeline has been exposed has been caused by erosion of the river

banks during high water flow events. While gabions are effective in mitigating the effects of erosion as well

as protecting the fuel pipeline, it is suggested that the proposed improvements and redesign of the gabion

installations be implemented in order to ensure that the environmental impacts of the project are minimised

(please refer to Section 2: Alternatives as well as specialist studies attached as Appendix D).

10. Will the benefits of the proposed land use/development outweigh the negative impacts of it?


The infrastructure is aimed at protecting the fuel pipeline from being exposed and susceptible to damage

which may lead to environmental pollution and health and safety risks.

11. Will the proposed land use/development set a precedent for similar activities in the area (local municipality)?


The proposed development was undertaken under emergency conditions and to protect the exposed fuel

pipeline. It is not anticipated that similar activities will be undertaken in the area, unless the mitigation of

erosion of river banks and bank stabilisation becomes a prioritised municipal project.

12. Will any person’s rights be negatively affected by the proposed activity/ies?


To date no person’s rights have been negatively affected by the proposed development.


20

13. Will the proposed activity/ies compromise the “urban edge” as defined by the local municipality?


The proposed activity occurs within the Moreleta Park, which is within the urban boundaries of the

municipality.

14. Will the proposed activity/ies contribute to any of the 17 Strategic Integrated Projects (SIPS)?


This proposed development is aligned with the SIP 2.

SIP 2: Durban-Free State-Gauteng Logistics and Industrial Corridor

The Transnet high pressure liquid petroleum pipeline traverses through 5 provinces, 3 of which are

KwaZulu-Natal, Free State and Gauteng. This pipeline therefore supplies fuel to various industries and

businesses located along the identified corridor, and are aligned to promoting the industrial corridor.

15. What will the benefits be to society in general and to the local communities?

Please explain

The reduction in potential environmental, health and safety risks should the exposed pipeline be

vandalised or damaged will benefit neighbouring property owners as well as properties downstream of the

pipeline exposure. The Moreleta Spruit which falls within the Faerie Glen Nature Reserve will continue to

support the ecological functioning of the wetland system, and therefore benefit society in general in terms

of the intrinsic value of conservation areas and urban “green lungs”.

16. Any other need and desirability considerations related to the proposed activity?

Please explain

No.

17. How does the project fit into the National Development Plan for 2030? Please explain

The National Development Plan (NDP) speaks to South African goals in terms of economic infrastructure development. One of the Enabling milestones of the plan is to:

“Upgrade fuel refineries to ensure they meet new fuel quality standards and insist on larger strategic fuel stocks to ensure security of supply.”

As such, the development is aligned to the NDP, as it the fuel pipeline will perform the function of supporting infrastructure to transport the liquid fuel and ensure the security of fuel supply to various provinces.

18. Please describe how the general objectives of Integrated Environmental Management as set out in section 23 of NEMA have been taken into account. The principles and objectives of Integrated Environmental Management are closely linked and a discussion on the one inherently involves reference to the other. As such and as per NEMA the general objectives of integrated environmental management are included in the section below in italics. A description of how each objective is related to and has been taken into account in this application for Environmental Authorisation is noted in red script below the statement in italics.

(a) promote the integration of the principles of environmental management set out in section 2 into the making of all decisions which may have a significant effect on the environment; The decision to undertake the development arose out of the need to minimise the potential impact of the environmental, health and safety risks associated with an exposed fuel pipeline on people and ecosystems in vicinity of the pipeline. The gabion construction project (as an example) integrates the principle that environmental management must place people and their needs at the forefront of its concern, and serve their physical, psychological, developmental, cultural and social interests equitably into the decision making process. Please also refer to 19 below for a discussion in terms of the principles of Environmental Management and Appendix J for an excerpt from NEMA in terms of the principles of Integrated Environmental Management.

(b) identify, predict and evaluate the actual and potential impact on the environment, socio-economic conditions and cultural

heritage, the risks and consequences and alternatives and options for mitigation of activities, with a view to minimising negative impacts, maximising benefits, and promoting compliance with the principles of environmental management set out in section 2; The key issues, potential impacts of the proposed facility and recommended mitigation measures have been identified and evaluated by the EAP and appointed specialists and detailed in the sections that follow. Please refer to Section D of this report which includes a description of the Methodology used for Impact Significance Scoring.

(c) ensure that the effects of activities on the environment receive adequate consideration before actions are taken in connection

with them; Yes, potential effects/ impacts of installing the gabions as erosion control measures and protection for the Transnet fuel pipeline have been considered in this Basic Assessment Process. As stated above each impact on the environment was identified and assessed by the EAP and the specialist team and mitigation measures recommended where possible and required. An Environmental Management Programme (EMP) has been compiled and attached to this document as Appendix G to ensure that these mitigation measures are implemented during the construction and operational phases of the proposed development.

(d) ensure adequate and appropriate opportunity for public participation in decisions that may affect the environment;

An equitable public participation process/ stakeholder engagement was undertaken in terms of Best Practise Public Participation Guidelines and principles. Key Stakeholders were identified through a focussed process (by identifying relevant authorities, organisations operating within Moreleta Park, and neighbouring property owners), and were notified of the project via e-mailed letters. The general public were notified in a local newspaper, in the predominant languages (English and Afrikaans) of the local community. Interested and affected parties were afforded the opportunity to comment and request additional information in any form of written communication acceptable to them. Site notices were also placed at the fences in close vicinity to the sites of construction, providing details of the public participation process, project background and contact details for further communication. Details of the public participation process will be included in Appendix E. A register will be kept of all Interested and Affected parties and the details will be used in all future communication in terms of the process and application for Environmental Authorisation. A public meeting is scheduled for 16 January 2013, at the Eastside Community Church in Moreleta Park.

(e) ensure the consideration of environmental attributes in management and decision-making which may have a significant effect

on the environment; and Wetland and Aquatic Specialist studies have been undertaken to assess the effects of the gabion construction on the wetland system function, and have identified mitigation measures and proposed methods to enhance the functioning of the gabion structures. The implementation of these measures will ensure that the impact on environmental attributes will be managed and minimised.

(f) identify and employ the modes of environmental management best suited to ensuring that a particular activity is pursued in accordance with the principles of environmental management set out in section 2.” The development has followed the modes outlined below to ensure that the activity is in accordance with the principles of environmental management: o Aligned to relevant municipal and district by-laws, spatial planning and environmental frameworks for the

proposed development area; o Ensure equitable public participation process was undertaken. o The adherence to the all the principles of NEMA, which would be implemented by the Environment

Management Programme (EMP) during construction and operation of the proposed facility. Refer to Appendix G for the Draft EMP for the proposed facility.

Lastly is it is assumed that the template for a Basic Assessment Report, as prepared by the Department, adheres to all provisions of the National Environmental Management Act in terms of Integrated Environmental Management (including the objectives and principles of NEMA) and the EAP has therefore endeavoured to provide as much detailed information as possible in the sections above and below.


22

19. Please describe how the principles of environmental management as set out in section 2 of NEMA have been taken into account.

The development involves the construction of gabions at two sites along the Moreleta Spruit to protect an exposed fuel pipeline from erosion.

The following points demonstrate how the principles in Section 2 of NEMA have been applied:

The potential pollution or degradation to the environment has been minimised through the proposed mitigation measures detailed in the EMP.

Although the site serves as an ecological corridor, it is already somewhat disturbed with some alien invasive vegetation and no cultural or heritage resources are present on the site.

Any general waste generated from the development during the construction phase was disposed of at the relevant registered waste facility.

The potential risks to human health have been considered and included in the assessment of impacts.

The construction of the gabions was undertaken as emergency measures to the fuel pipeline, and all applicable environmental and international legislation/standards and any other applicable legislation or standards will be adhered to and authorisation applied for retrospectively.

Throughout the Basic Assessment process information has been made freely available to any Interested and Affected Party requesting information ensuring transparency in the process.

SECTION D: IMPACT ASSESSMENT The assessment of impacts must adhere to the minimum requirements in the EIA Regulations, 2010, and should take applicable official guidelines into account. The issues raised by interested and affected parties should also be addressed in the assessment of impacts.

Methodology for Impact Significance Scoring

The significance (quantification) of potential environmental impacts identified during the Basic Assessment have been determined using a ranking scale, based on the following (terminology has been taken from the Guideline Documentation on EIA Regulations, of the Department of Environmental Affairs and Tourism, April 1998): Occurrence

Probability of occurrence (how likely is it that the impact may occur?)

Duration of occurrence (how long may it last?) Severity

Magnitude (severity) of impact (will the impact be of high, moderate or low severity?)

Scale/extent of impact (will the impact affect the national, regional or local environment, or only that of the site?) Each of these factors has been assessed for each potential impact using the following ranking scales:

The environmental significance of each potential impact is assessed using the following formula:

Significance Points (SP) = (Magnitude + Duration + Extent) x Probability

Probability Duration 1 - very improbable (probably will not happen 2 - improbable (some possibility, but low likelihood) 3 - probable (distinct possibility) 4 - highly probable (most likely) 5 - definite (impact will occur regardless of any prevention measures)

1 - of a very short duration (0–1 years) 2 - of a short duration (2-5 years) 3 - medium-term (5–15 years) 4 - long term (> 15 years) 5 - permanent

Extent Magnitude 1 - limited to the site 2 - limited to the local area 3 - limited to the region 4 - will be national 5 - will be international

0 - small and will have no effect on the environment 2 - minor and will not result in an impact on processes 4 - low and will cause a slight impact on processes 6 - moderate and will result in processes continuing but in a modified way 8 - high (processes are altered to the extent that they temporarily cease) 10 - very high and results in complete destruction of patterns and permanent cessation of processes


39

The maximum value is 100 Significance Points (SP). Potential environmental impacts were rated as high, moderate or low significance on the following basis: < 30 significance points = LOW environmental significance. 31- 60 significance points = MODERATE environmental significance > 60 significance points = HIGH environmental significance

The table below summarises all the identified impacts and their significance ratings without and with mitigation, while detailed descriptions of each impact are provided there under.

Note there are no feasible alternatives for the gabion construction at the Moreleta Spruit EXCEPT the NO GO Alternative. 1. IMPACTS THAT MAY RESULT FROM THE PLANNING AND DESIGN, CONSTRUCTION,

OPERATIONAL, DECOMMISSIONING AND CLOSURE PHASES AS WELL AS PROPOSED MANAGEMENT OF IDENTIFIED IMPACTS AND PROPOSED MITIGATION MEASURES

Provide a summary and anticipated significance of the potential direct, indirect and cumulative impacts that are likely to occur as a result of the planning and design phase, construction phase, operational phase, decommissioning and closure phase, including impacts relating to the choice of site/activity/technology alternatives as well as the mitigation measures that may eliminate or reduce the potential impacts listed. This impact assessment must be applied to all the identified alternatives to the activities identified in Section A (2) of this report. Note: There are no planning and design phase impacts associated with the proposed development. Refer below for the construction phase, operational phase, decommissioning phase impacts identified and assessed.

2 4 2 2 16

Low

Regular maintenance must ensure that the gabions do not promote soil erosion. Design alternatives provided in section 2 of this report and the specialist reports (Appendix D) must be implemented.

Indirect impacts: Increased traffic in the system: the gabions may be used as a bridge across the watercourse, and therefore increase traffic in the system, which will impact on the surrounding vegetation. Maintenance activities required may also impact on vegetation and small animals and insects. As a result there would be a Low significance impact (Negative).



3 4 2 2 18

Low

Maintenance operations should be limited to the gabion sites, and no unnecessary traffic outside the demarcated area should be undertaken, so as to minimise potential impacts. The use of the gabions as bridges should be restricted.

No-go option

Direct impacts:

The No Go Alternative refers to the development not occurring. As such the following positive benefits would not come to light:

- The protection of the fuel pipeline: the construction of

Moderate environmental significance (Negative)

N/A


46


gabions in the Moreleta Spruit is aimed at protecting the fuel pipeline from further exposure and potential damage and leaks.

- Reduction of soil erosion: the channel erosion upstream from the gabions will be decreased, and the eroded areas will fill up again. The downstream area may also erode less.

- Water table: the water table may be lifted due to the flow

velocity reduction from the gabions, which may improve vegetation quality and wetland functioning.

As noted, the above benefits would not come to light if the project is not authorised and have to be decommissioned. As such the overall cumulative impact of not constructing gabions in the Moreleta Spruit is negative, with a moderate environmental significance.

Low

Demolition operations should be limited to the gabion sites, and no unnecessary traffic outside the demarcated area should be undertaken, so as to minimise potential impacts.

Direct impacts: Soil erosion: the demolition of the gabions will result in restoration of the site prior to construction. This implies that erosion will continue along the banks of the river, particularly at the two sites where the fuel pipeline has been exposed. As a result there would be a Moderate significance impact (Negative).

2. ENVIRONMENTAL IMPACT STATEMENT Taking the assessment of potential impacts into account, please provide an environmental impact statement that summarises the impact that the proposed activity and its alternatives may have on the environment after the management and mitigation of impacts have been taken into account, with specific reference to types of impact, duration of impacts, likelihood of potential impacts actually occurring and the significance of impacts. As is evident from this report, the motivation for the construction and operation of the gabion structures within the Moreletta Spruit is rooted in the negative impact of uncontrolled erosion on the structural integrity of the Transnet high pressure liquid petroleum pipeline and the subsequent impact on the social and biophysical environment if said structural integrity is compromised. This assessment illustrates that there are various potential negative and positive impacts that may result from the construction and operation of the gabion infrastructure, although with the implementation of applicable mitigation measures, the negative impacts can be satisfactorily minimised.


49

The alternatives proposed included design alternatives recommended by the specialist as mitigation measures in terms of the unlawful commencement of the activity.

Key:

The table indicates that with the implementation of mitigation measures, all impacts will be of low significance to the receiving environment. However, given the ecological value and considering that the proposed site forms part of the biodiversity corridor of the Faerie Glen and Rietvlei Nature Reserves, the design alternatives suggested in section 2 of this report and the specialist reports (Appendix D) should be implemented to ensure that the positive impacts identified for the gabion structures are highlighted. Health and Safety Impacts is an important environmental aspect requiring careful mitigation and control. The danger of fire or explosion as a result of damage to the exposed fuel pipeline can have detrimental effects such as fatalities and damage to infrastructure. Ensuring that the fuel pipeline remains protected together with implementing the monitoring measures included into the Environmental Management Programme (See Appendix G) is essential to the sustainability of this project. Several mitigation measures have been proposed to minimise the anticipated environmental impacts together with an environmental management programme report to monitor the effectiveness of these mitigation measures.

Alternative A (preferred alternative)

In terms of the provisions of NEMA, the objectives and principles of Integrated Environmental Management and in the light of the potential impacts detailed above, it is the EAPs recommendation that the activity (Alternative A) be authorised with the condition that all mitigation measures recommend by the specialist be implemented. The EAP further recommends that a limited timeframe be set for the implementation of the mitigation measures.

No-go alternative (compulsory)

The “No-Go” alternative was briefly assessed and compared as shown above.

The gabion construction has positive environmental and health and safety impacts. The purpose of the gabion structure is to protect the fuel pipeline from exposure by the erosive action of the river during high flow periods. Therefore in the event that the application is not authorised the structural integrity of the pipeline will be compromised and the benefits to the receiving environment will not be realised.
