The solar farm will be located within the Farm Wolvehuis 114 on the Remaining Extent of Portion 7 and the Remaining Extent of Portion 21. The proposed project site falls under the jurisdiction of the City of Matlosana Local Municipality and within the greater Dr Kenneth Kaunda District Municipality in the North West Province. The contracted capacity of the solar farm will be up to 100MW and is proposed to accommodate several arrays of tracking or static PV panels and associated infrastructure on the proposed project site. The proposed solar farm is planned to be bid into the Department of Energy’s Renewable Energy Independent Power Producers Procurement (REIPPP) Programme with the aim of evacuating the generated power into the Eskom national electricity grid and aiding in the diversification and stabilisation of the country’s electricity supply. Photovoltaic (PV) technology is proposed to be utilised for the generation of solar electricity. The solar farm will include the following infrastructure: Arrays of PV panels (either a static or tracking PV system) with a capacity of up to 100MW; Mounting structures to support the PV panels; On-site inverters to convert the power from a direct current to an alternating current and a substation to facilitate the connection between the solar farm and the Eskom electricity grid; A new 132kV power line between the on-site substation and the Eskom grid connection point; Cabling between the project components, to be laid underground where practical; Offices and workshop areas for maintenance and storage; Temporary laydown areas; and Internal access roads and fencing around the development area. 2 PURPOSE OF REPORT This report assesses the expected traffic and transport impact during the Construction Phase, Operation Phase and Decommissioning Phase. 3 TRAFFIC SPECIALIST CREDENTIALS This Site Assessment is undertaken by Mr. S Fautley, who is a Professional Engineering Technologist registered with the Engineering Council of South Africa (ECSA). 3 TJ1636WC His career encompasses the civil, traffic and transportation engineering discipline for ten (10) years at the Western Cape Government, 1,5 years with Kantey and Templer Consulting Engineers and 10 years at local authority (City of Cape Town) before joining Techso in 2008, as a Senior Transport Engineer. He has extensive experience in Traffic Impact Assessments, and Site Assessments, including various renewable energy plants in South Africa and is a registered Road Safety Auditor. 4 IMPACT ASSESSMENT METHODOLOGY This report assesses the expected traffic and transport impact during the Construction Phase, Operation Phase and Decommissioning Phase of the proposed 100MW Orkney Solar Farm. The requirements in the TMH 16 Vol 1 & 2 South African Traffic Impact and Site Traffic Assessment Manual, August 2012, compiled by the Committee of Transport Officials (COTO) were used for this study. The Impact Assessment Methodology assists in evaluating the overall effect of a proposed activity on the environment. The environmental impact is determined through a systematic analysis of the various components of the impact. This is undertaken using information that is available to the environmental practitioner through the process of the environmental impact assessment. The impact evaluation of predicted impacts is undertaken through an assessment of the significance of the impacts. 4.1 Determination of Significance of Impacts Significance is determined through a synthesis of impact characteristics which include context and intensity of an impact. Context refers to the geographical scale i.e. site, local, national or global whereas Intensity is defined by the severity of the impact e.g. the magnitude of deviation from background conditions, the size of the area affected, the duration of the impact and the overall probability of occurrence. Significance is calculated as shown in Section 2.3. Significance is an indication of the importance of the impact in terms of both physical extent and time scale, and therefore indicates the level of mitigation required. The total number of points scored for each impact indicates the level of significance of the impact. 4.2 Impact Rating System Impact assessment must take account of the nature, scale and duration of effects on the environment whether such effects are positive (beneficial) or negative (detrimental). Each issue / impact is also assessed according to the project stages: » Planning (Not applicable in this instance – no traffic impact) » Construction 4 TJ1636WC » Operation » Decommissioning Where necessary, the proposal for mitigation or optimisation of an impact should be detailed. A brief discussion of the impact and the rationale behind the assessment of its significance has also been included. A rating system is used to classify impacts. The rating system is applied to the potential impact on the receiving environment and includes an objective evaluation of the mitigation of the impact.
