EXECUTIVE SUMMARY 1 Introduction

Lokisa Environmental Consulting was appointed by deBruin and Associates (Pty) Ltd on behalf of

the Department of Public Works and Roads: North West Province to submit an application for the

proposed rehabilitation of Road P31/1 (R104) stretching from the Gauteng Border to Road 123/1

(R560 to Magaliesburg) as well as all culverts and the bridge over the Leeuwenspruit to

Department of Rural, Environment and Agricultural Development (NWREAD) in terms of the

National Environmental Management Act (NEMA) (Act No. 107 of 1998), as amended and the

Environmental Impact Assessment Regulations, published on 4 December 2014.

2 Project Description

The project entails the rehabilitation as well as the widening of the road (in some sections) of

Road P31/1 (R104) from the Gauteng border to Road 123/1 (R560 to Magaliesburg) as well as

the culverts and the bridge over the Leeuwenspruit. The road measures approximately 22km in

extent. Existing storm water infrastructure will be replaced/extended and new storm water

infrastructure will be constructed.

The proposed construction entails the following but not limited to:

1. Contractor’s establishment on site

2. Provisions of temporary workforce (ABE)

3. Training of temporary workforce

4. Housing, offices and laboratories for the engineer’s personnel

5. Survey and relocation of services

6. Clearing and grubbing (green fields portion) within the existing road reserve;

7. Topsoil will be stripped and stored;

8. Construction of temporary bypasses where required using the existing road and

reconstructed shoulders (two way traffic flow)

9. Roadbed preparation and Layer works construction;

10. Installation of overland storm water measures to mitigate erosion and manage storm water

11. Landscaping and planting plants

12. Finishing of road, road reserve

13. Testing and workmanship

14. Repair the robot or traffic signal at the NECSA intersection

15. Maintaining the Works during the construction and defects liability period

16. Possible new robot at Oberon intersection

The project can be broken down in three phases being:

Phase 1 - from 19.76km to 26.16km. The existing road width is 11m and a 2.9m new/extra

widening (to include widening on both sides 2 x 1.45m =2.9m) is proposed which will bring the

width of the rehabilitated road to 13.9m. Stormwater & drainage line culverts under the road

(R104 & R512) earmarked for upgrade will also be upgraded. The culverts will either be replaced,

additional pipes to improve flow inserted, or lengthened where necessary.

Phase 2A - from 26.16km to 35.89km. Upgrade of this section of the road to undivided four (4)

lanes dual carriageway. Almost 62% of this section of the road has 3 lanes and the carriage width

is to be increased to 15.8m. The widening of the Leeuwenspruit Bridge is also included in this

phase. The construction and operation of the bridge will be on one or both sides of the river. The

construction of the bridge will be a “slab” (concrete platform) supported by pillars located

(positioned) mainly on the river banks. Stormwater & drainage line culverts under the road (R104

& R512) earmarked for upgrade will also be upgraded. The culverts will either be replaced,


Phase 2B - from 35.89km to 41.76km. The existing road width is 11m and a 2.9m new/extra

widening (to include widening on both sides 2 x 1.45m=2.9m) is proposed which will bring the

width of the rehabilitated road to 13.9m. Stormwater & drainage line culverts under the road

(R104 & R512) earmarked for upgrade will also be upgraded. The culverts will either be replaced,


Construction is estimated to commence with Phase 1 during March/April 2019 and to last for 10

months where after Phases 2A and B will take place (estimated to take approximately 24

months).

3 Site attributes

The road is situated south of Hartbeespoort Dam and stretches from the Gauteng Border (at

Pelindaba) to the T-Junction with the R560 to Scheerpoort within the Madibeng Local

Municipality.

Phase 1 is 6.4km in length and this section of the road is located in the vicinity of Pelindaba,

where the Road commences at the Gauteng Border, crosses the Crocodile River and continues

westward to the P103/2 (Lanseria Road) intersection.

Phase 2 of the road is located to the south of the Hartbeespoort Dam and extends from the

P103/2 (Lanseria Road) to the Leeuwenspruit bridge, crossing the Leeuwenspruit, and from

there to the T-Junction with the P123/1 (towards Sun City). Culverts are to be upgraded and the

Leeuwenspruit Bridge is to be expanded.

Phase 2B is 5.87km in length and stretches from 35.89km – 41.76km. This section of the road is

located to the south west of the Hartbeespoort Dam, where the road commences at the T-

Junction with the R512 (road towards Sun City) and continues westward to the T-Junction with

the R560.

The characteristics of the area in which the road is situated is mainly Rural residential in nature

with a strong focus of low intensity rural tourism corridor along the R104. Environmentally

sensitive areas are located in the central part of the project and the western portion of the area is

characterised by Residential developments. Commercial uses are also located adjacent to the

existing road.

From a biophysical point of view the project falls inside the existing road reserve and the

vegetation of the study site is representative of Andesite Mountain Bushveld, but with levels of

degradation and disturbance, which has led to the encroachment of acacia thorn trees as well as

some other invasive alien weeds trees species such as gum (eucalypt), syringe and poplar. A

Wetland and Riparian delineation and status report was undertaken for the Widening and

Upgrading of the Bridge on the Leeuwenspruit by Flori Scientific Services.

A total of 13 natural watercourses are found along the road and 2 are classified as non-perennial

ephemeral rivers (no flow for 3 – 6 months) The watercourses that are crossed by the ROAD

P31/1 (R104) are likely to be impacted to some extent by the proposed upgrade and widening as

a result of the upgrade of the culverts that are proposed. No expansion is proposed for the bridge

over the Crocodile River. Approximately 40 culverts are to be upgraded as construction takes

place and the bridge over the Leeuwenspruit is to be extended.

Leeuwenspruit (on which the bridge to be extended is located) flows in a north-east direction, and

confluences with the Broederstroom, which flows north for approximately 1 km and into the

Hartbeespoort Dam.

No buildings, structures and or other features of cultural or heritage significance will be impacted

upon, however a chance find procedure will be implemented in the Environmental Management

Programme as per the Specialist’s recommendation.

4 Regulatory Environmental Requirements

The Department of Rural, Environment and Agricultural Development (NWREAD), is the lead

authority carrying out the authorisation process in accordance with the National Environmental

Management Act (Act No. 107 of 1998, “NEMA”) (as amended).

The EIA Regulations under the NEMA consist of two categories of activities namely: Listing

Notices 1 and 3 Activities (GNR. 327 and GNR 324 of 2014) which require a Basic Assessment

Process, for authorisation.

5 Basic Assessment Report

The template for the Basic Report has been obtained from NWREAD and is in line with the

requirements of the NEMA EIA Regulations.

No off-site or other site alternatives were investigated as the project entails the upgrade of an

existing road. The alternatives for the project are the following: Alternative 1: Use existing

shoulder to accommodate traffic during the construction phase; Alternative 2: Provide temporary

deviation on both sides of the existing road (outside the existing road reserve). The impacts of

each alternative is assessed in Section C and Alternative 1 is the preferred alternative.

The do-nothing (“no go”) option would entail not upgrading and widening the existing road and

maintaining the road as is. The No-go option is considered to be the most undesired alternative

as one of the functions of the proposed upgraded route will be to provide adequate capacity for

the expected increase in traffic and will further provide improving future development potential

and quality of life of local communities.

6 Public Participation

Lokisa Environmental Consulting CC conducted the Public Participation Process (PPP) for the

project. For the PPP, the aim was to ensure that the full range of stakeholders was informed

about the development throughout the period in question.

The Draft Report was made available for public review from 10 September 2018 to 11 October

2018. The Final Report was submitted to I&AP’s on 24 October 2018.

7 Environmental Impact Assessment

The impacts of the project activities were determined by identifying the environmental aspects

and then undertaking an environmental risk assessment to determine the significant

environmental aspects.

The environmental impact assessment has considered all phases of the project, namely,

construction, operational and closure/rehabilitation phase. It is not anticipated that the proposed

infrastructure will be decommissioned and therefore, the decommissioning impacts have not been

considered.

The rating system used is applied to the potential impact on the receiving environment and

includes an objective evaluation of the mitigation of the impact. During the Basic Assessment, the

impact of the project on the biophysical and socio-economic environments was assessed. It was

this assessment that allowed the EAP to make an informed analysis and provide an opinion of the

proposed development.

8 Conclusion

In line with the requirements of the NEMA EIA Regulations (2014), this Basic Assessment has

provided, an explanation of the activities undertaken during the Basic Assessment. The public

participation process has been inclusive, and every effort has been made to include the

representations of all stakeholders within the process.

The BAR provides an assessment of both the benefits and potential negative impacts anticipated

as a result of the proposed project. It further provides a description of the affected environment

and alternatives proposed for the upgrade of Road P31/1 (R104).

Based on the comparative assessment of the two alternatives and the impact identification and

assessment, it is evident that there is some difference with regard impacts from Alternative 1 in

comparison to Alternative 2. The majority of the impacts, which have contributed to the greater

impact rating score of Alternative 2 compared to Alternative 1, relate to impact on hydrology,

safety during construction, waste creation, cost and impact on existing access.

Should the proposed mitigation measures be implemented accordingly, the findings conclude that

there are no significant environmental fatal flaws that could prevent the development to proceed.

Furthermore, the recommendations and management measures are contained in the

Environmental Management Programme.

Definitions

Access road A road providing a means of entry into a region or of approach to another road especially a motorway.

Activity (Development) An action either planned or existing that may result in environmental impacts through pollution or resource use. For the purpose of this report, the terms ‘activity’ and ‘development’ are freely interchanged.

Alignment The route of the road, defined as a series of horizontal tangents and curves.

Alternatives Different means of meeting the general purpose and requirements of the activity, which may include site or location alternatives; alternatives to the type of activity being undertaken; the design or layout of the activity; the technology to be used in the activity and the operational aspects of the activity.

Applicant The project proponent or developer responsible for submitting an environmental application to the relevant environmental authority for environmental authorisation.

Biodiversity The diversity of animals, plants and other organisms found within and between ecosystems, habitats, and the ecological complexes.

Carriageway Part of the road intended for the movement of road motor vehicles; the parts of the road which form a shoulder for the lower or upper layers of the road surface are not part of the roadway, nor are those parts of the road intended for the circulation of road vehicles which are not self-propelled or for the parking of vehicles

Construction The building, erection or establishment of a facility, structure or infrastructure that is necessary for the undertaking of a listed or specified activity but excludes any modification, alteration or expansion of such a facility, structure or infrastructure and excluding the reconstruction of the same facility in the same location, with the same capacity and footprint.

Cumulative impact The impact of an activity that in itself may not be significant but may become significant when added to the existing and potential impacts eventuating from similar or diverse activities or undertakings in the area.

Curb A raised edge at the side of the roadway Decommissioning The demolition of a building, facility, structure or infrastructure. Derelict land means abandoned land or property where the lawful/legal land use

right has not been exercised during the preceding ten year period (Regulation R982 of NEMA, 1998 (Act No. 107 of 1998));

Direct Impact Impacts that are caused directly by the activity and generally occur at the same time and at the same place of the activity. These impacts are usually associated with the construction, operation or maintenance of an activity and are generally quantifiable.

Ecosystem A dynamic system of plant, animal (including humans) and micro-organism communities and their non-living physical environment



interacting as a functional unit. The basic structural unit of the biosphere, ecosystems are characterised by interdependent interaction between the component species and their physical surroundings. Each ecosystem occupies a space in which macro-scale conditions and interactions are relatively homogenous

Environment In terms of the National Environmental Management Act (NEMA) (No 107 of 1998)(as amended), “Environment” means the surroundings within which humans exist and that are made up of: a) the land, water and atmosphere of the earth; b) micro-organisms, plants and animal life; c) any part or combination of (i) of (ii) and the interrelationships among and between them; and d) the physical, chemical, aesthetic and cultural properties and conditions of the foregoing that influence human health and wellbeing.

Environmental Assessment

The generic term for all forms of environmental assessment for projects, plans, programmes or policies and includes methodologies or tools such as environmental impact assessments, strategic environmental assessments and risk assessments.

Environmental Authorisation An authorisation issued by the competent authority in respect of a listed activity, or an activity which takes place within a sensitive environment.]

Environmental Assessment Practitioner (EAP)

The individual responsible for planning, management and coordination of environmental impact assessments, strategic environmental assessments, environmental management programmes or any other appropriate environmental instrument introduced through the EIA Regulations.

Environmental Management Ensuring that environmental concerns are included in all stages of development, so that development is sustainable and does not exceed the carrying capacity of the environment.

Environmental Management Programme (EMPr)

A detailed plan of action prepared to ensure that recommendations for enhancing or ensuring positive impacts and limiting or preventing negative environmental impacts are implemented during the life cycle of a project. This EMPr focuses on the construction phase, operation (maintenance) phase and decommissioning phase of the proposed project.

Environmental Impact Change to the environment (biophysical, social and/ or economic), whether adverse or beneficial, wholly or partially, resulting from an organisation’s activities, products or services.

Environmental Issue A concern raised by a stakeholder, interested or affected parties about an existing or perceived environmental impact of an activity.

Fatal Flaw Issue or conflict (real or perceived) that could result in developments being rejected or stopped. In the context of an environmental impact assessment a fatal flaw can be termed as an environmental issue that cannot be mitigated by any means

General Waste Household water, construction rubble, garden waste and certain dry industrial and commercial waste, which does not pose an immediate threat to man or the environment.

Groundwater Water in the ground that is in the zone of saturation from which wells, springs, and groundwater run-off are supplied.

Hazardous Waste Waste that may cause ill health or increase mortality in humans, flora and fauna.

Hydrology The science encompassing the behaviour of water as it occurs in the atmosphere, on the surface of the ground, and underground.



Indirect Impacts Indirect or induced changes that may occur as a result of the activity. These types if impacts include all of the potential impacts that do not manifest immediately when the activity is undertaken or which occur at a different place as a result of the activity.

Integrated Environmental Management

A philosophy that prescribes a code of practice for ensuring that environmental considerations are fully integrated into all stages of the development and decision making process. The IEM philosophy (and principles) is interpreted as applying to the planning, assessment, implementation and management of any proposal (project, plan, programme or policy) or activity – at local, national and international level – that has a potentially significant effect on the environment. Implementation of this philosophy relies on the selection and application of appropriate tools for a particular proposal or activity. These may include environmental assessment tools (such as strategic environmental assessment and risk assessment), environmental management tools (such as monitoring, auditing and reporting) and decision-making tools (such as multi-criteria decision support systems or advisory councils).

Interested and Affected Party (I&AP) Any person, group of persons or organisation interested in or affected by an activity; and any organ of state that may have jurisdiction over any aspect of the activity.

Lane One of the longitudinal strips into which a carriageway is divisible, whether or not defined by longitudinal road markings, which is wide enough for one moving line of motor vehicles other than motor cycles

Mitigate The implementation of practical measures designed to avoid, reduce or remedy adverse impacts or enhance beneficial impacts of an action.

No-Go Option In this instance the proposed activity would not take place, and the resulting environmental effects from taking no action are compared with the effects of permitting the proposed activity to go forward.

Public Participation Process A process in which potential interested and affected parties are given an opportunity to comment on, or raise issues relevant to, specific matters.

Public Road Means any road, street or thoroughfare or any other place (whether a thoroughfare or not) which is commonly used by the public or any section thereof or to which the public or any section thereof has a right of access, and includes- (a) the verge of any such road, street or thoroughfare-, (b) any bridge, ferry or drift traversed by any such road, street or thoroughfare; and (c) any other work or object forming part of or connected with or belonging to such road, street or thoroughfare.

Rehabilitation A measure aimed at reinstating an ecosystem to its original function and state (or as close as possible to its original function and state) following activities that have disrupted those functions.

Roadway Means that portion of a road, street or thoroughfare improved, constructed or intended for vehicular traffic which is between the edges of the roadway

Roadworks Part or all of the road is occupied for work or maintenance Sensitive Environments Any environment identified as being sensitive to the impacts of the

development. Significance Significance can be differentiated into impact magnitude and

impact significance. Impact magnitude is the measurable change (i.e. magnitude, intensity, duration and likelihood). Impact significance is the value placed on the change by different affected parties (i.e. level of significance and acceptability). It is an anthropocentric concept,



which makes use of value judgements and science-based criteria (i.e. biophysical, social and economic).

Shoulder A clear, level area to the side of the roadway available for stopping if needed.

Stakeholder Engagement The process of engagement between stakeholders (the proponent, authorities and I&APs) during the planning, assessment, implementation and/or management of proposals or activities.

Sustainable Development Development which meets the needs of current generations without hindering future generations from meeting their own needs.

Alternative 3

Not Applicable

e) No-go alternative

With the no-go alternative the upgrade of the existing road does not take place with negative consequences for both the objectives of the Department of Roads, the Provincial and Local Authorities. Furthermore the safety of the existing and future road users will be negatively impacted upon. This option will see the further increase in deterioration of the road and possibly have an impact on road safety as a result of the number of vehicles and trucks that make use of the road. The road is furthermore the only available road that forms an east to west linkage to the south of Hartbeespoort dam and if not upgraded a new road may have to be built. The construction of new roads have an impact on the ecological resources, cause displacement of species, deteriorating ecosystem, pollution, hydrological and erosion effects.
