    EXECUTIVE SUMMARY

    A Traffic Impact Study was prepared as part of the consolidated environmental impact assessment (EIA) and environmental management plan (EMP) for the proposed Acetylene Gas Production Plant project for the EMP application and will include a gas production plant and pipelines associated with the production facility and associated entities.

    The proposed Acetylene Gas Production Plant will be developed on Erf 88 and Erf 89 of the Farm Valley Agricultural Holdings, Witkopdorp (Daleside) south of Johannesburg.

    The site is located approximately 9km north of the Meyerton CBD and 45km south of the Johannesburg CBD in the Gauteng Province.

    The proposed Acetylene Gas Production Plant on Erf 88 and Erf 89 will be developed for the production of gas similar as existing gas production operations in South Africa.

    The possible life span of the plant was estimated between 40 and 50 years. Fore the purpose of this study a 20 year life was assumed to reach full design capacity of the plant. The proposed Acetylene Gas Production Plant will have a staff complement of 20 permanent job opportunities.

    ITS (Pty) Ltd was appointed by Environmental Resources Management Southern Africa (Pty) Ltd on behalf of Air Products South Africa (Pty) Ltd to carry out a Traffic Impact Assessment for the proposed Acetylene Gas Production Plant development in accordance with the Manual of Traffic Impact Studies published by the Department of Transport, 1995.

    The purpose of this report is to provide findings of the traffic investigation conducted to assess the impact of the proposed Acetylene Gas Production Plant activity on the existing external road networks surrounding the development area. Based on this assessment, mitigation measures are recommended for the proponent to minimise the potential impacts on the existing road network. The following tasks have been carried out as part of the traffic impact investigation: Collection of traffic information to determine the status quo of the existing road

    network operations; Determination of the trip generation due to the proposed Acetylene Gas

    Production Plant development; Assessing the impact of the trips generated by the proposed Acetylene Gas

    Production Plant, on the road network (capacity analysis of the affected routes including the intersection analysis);

    Safety Statement: an assessment of the access position in terms of geometrical standards (UTG 1 manual, site distance, stopping site distances etc.);

    Public transport provision to accommodate the public transport users for the proposed Acetylene Gas Production Plant employees;

    A detailed proposal of site specific mitigations, if and where applicable.

    Assessment Methodology The main phases of the project have been identified as follows: pre-construction phase (2014 to 2015), construction phase (2015 to 2019), operational phase (2019 to 2030) and closure and decommissioning phase (2030). The critical impact in terms of the traffic generated is expected to be during the operational phase. The following scenarios were considered for assessment: 2013 Existing Traffic Volumes, Construction Phase: 2018 projected traffic demand, Operational phase: 2038 projected traffic demand, Decommissioning Phase: 2039 projected traffic demand.

    Findings The finding of this investigation can be summarised as follows:

    The Tilliet Rd is a gravel road between the proposed Acetylene Gas Production Plant site access point and Tilliet / Kalksteen Road intersection.

    Kalksteen Road is a paved road and links Tilliet Road with the M61 (K89) Road.

    The M61 (K89) Road located east of the proposed Acetylene Gas Production Plant site is a future planned provincial K-route.

    The future alignment of the K89 route will impact on Tilliet Road and access to Tilliet Road would be provided from Kalksteen Road.

    Both Tilliet / Kalksteen Road and Kalksteen / M61 Road intersections are priority controlled intersections with priority on Kalksteen Road and the M61 Road respectively.

    Access to the proposed Acetylene Gas Production Plant site would be provided from Tilliet Road.

    It is expected that the access intersection would operate at an acceptable LOS once the proposed development is fully operational.

    The construction phase is anticipated to be the critical period in terms of additional trips generation. The trips generation prediction for that period is in order of 96 vehicle trips during the AM and PM Peak Hours. The addition
