SOCIO ECONOMIC IMPACT ASSESSMENT FOR THE OLIFANTSFONTEIN LANDFILL SITE, EKURHULENI METROPOLITAN MUNICIPALITY, GAUTENG APRIL 2021 Submitted to: Submitted by: AND EXECUTIVE SUMMARY Summer Symphony Properties 264 CC. is the landowner of Portions 41 and 179 of the farm Olifantsfontein 410 JR, in the Olifantsfontein area. The landowner has an existing Waste Management Licence for a category G:L:B- landfill facility, referred to as the Olifantsfontein Landfill. The site is situated in Ward 1 of the City of Ekurhuleni Metropolitan Municipality and located to the east of Midrand and east of the Glen Austin Agricultural Holdings, west of the K111 (Republic Road) and approximately 1.5 km south of the R562 (Olifantsfontein Road). Tembisa is located to the east and south-east of the site. The Clayville/Olifantsfontein industrial area is to the north east and the Randjiesfontein Agricultural Holdings to the north west. The Olifantsfontein Landfill site can be viewed as a Brownfields site disturbed by sand quarrying and is approximately 45 ha in extent. The site is zoned as “agricultural”. Access to the site would be from the K111. The site is authorized to receive inert waste, garden waste and building rubble. Construction of the site has commenced. The License Holder intends to apply for an amendment of the Olifantsfontein Waste Management Licence to allow the acceptance of general wastes comprising general- domestic, commercial, garden, builder’s rubble and general dry industrial waste for disposal. The landfill site would require a class B lining system for the disposal of general waste as prescribed by Regulation 636 promulgated under the National Environmental Management: Waste Act (Act 59 of 2008). On average it is expected that the landfill could receive around 15 000 tons of waste per month or 500 tons/day. The project, however, will have a design capacity in excess of 1000 tons/day. The landfill has around 3.5 million cubes of airspace which indicates to a lifespan of between 15 to 30 years. The site development plan consists of the following: Infrastructure and facilities Access road, perimeter service road and on-site roads Perimeter fencing and entrance gate and control Storm water drainage measures Office, ablutions and stores building Weighbridges Recycling yard and building Composting yard Landfill cells, and Contaminated storm water run-off/leachate evaporation dam. A Materials Recovery Facility (MRF) will form part of the facility. The main access roads on site would be paved. Dust suppression on the gravel roads would be by means of wetting. The landfill area will be subdivided into seven (7) cells and the development of each of these cells will be phased. Ekurhuleni Ward 102 lies east of the landfill, City of Johannesburg (CoJ) Ward 92 is situated west of the landfill and CoJ Wards 77 and 133 is situated south of the landfill. Generally, socio-economic i impacts of landfills occur within a 1km to 4km radius from landfill sites. Within the 4km radius the following receptors should be noted: High density residential areas to the south (towards Tembisa) Low density plots of Glen Austin and Randjiesfontein to the west Parts of Olifantsfontein industrial area and Tembisa’s Clayville are located within the 4km boundary east from the landfill A retail complex (Cashbuild) still under construction at the time of this study, lying within the 1km boundary of the site (north east) in Tswelopele (Tembisa) Parts of Kaalspruit (flowing in a northerly direction towards Centurion in CoT) within 1km from the site Olifantsfontein road (R562) passing some 1km north of the proposed site Glen Austin Bird Sanctuary to the south west of the landfill within the 4km radius. During the construction phase, the landfill created around 38 direct job opportunities and 25 flow- on jobs for two and a half years, as the construction of the cells occur in a phased manner. This is the full time equivalent (FTE) of 95 direct jobs and 63 flow-on jobs for one year. During the operational phase it is anticipated that the landfill will create in the region of 7 direct jobs during the operational lifetime of the facility. About 5 of these positions could be filled by unskilled workers; 1 semi-skilled site operator and 1 skilled supervisor. The landfill site will thus have direct positive impacts on income and employment created and will result in further indirect positive economic impacts to local suppliers and as a result of the overall increase in income levels and increased spending. One can expect the operations to lead to some inflow of jobseekers (which have likely already been caused by the construction of the recently completed Mall of Tembisa) and more so to some informal reclaimers (waste pickers) to the site, as the landfill site can be easily accessed from the K111 and the Olifantsfontein road (R562). Negative impacts in this regard can be mitigated. Dust created during the construction phase, mainly by vehicles travelling on gravel roads, as well as the actual operations such as wind erosion from exposed surfaces, the compacting of waste and handling of material can have impacts on the air quality with subsequent negative impacts on human health. The Air Quality Impact Assessment (AQIA) however found that the predicted impacts would be low over the areas surrounding the proposed landfill site and fall well within the residential and non-residential area standards (for dust-fall), and the daily and annual SNAAQS. Hazardous air pollutants (HAP) are associated with malodour impacts. In the case of the Olifantsfontein landfill, the AQIA stated that residents located in near proximity south, south-east and east of the proposed landfill could potentially experience odour impacts, but that the possible impacts can be mitigated through the implementation of proper waste control management systems and the implementation of different leachate treatment options. The potential increase in crime rates and other security issues in the local area mainly relate to the movement of vehicles, the influx of an outside workforce and potential jobseekers, as well as the presence of reclaimers on site. Proper landfill management can address and mitigate these possible impacts. ii Ground and surface water pollution is a concern usually associated with landfill sites. With regards to the Olifantsfontein landfill, this risk is anticipated to be low due to the low percentage of downstream borehole users and the lower population densities downstream from the landfill. The underlying groundwater aquifer is located more than 20m beneath the landfill floor level and is considered to be a Minor Aquifer. Proper design of a storm water and groundwater control system will limit the risks in this regard. Various ‘nuisance’ factors (noise, dust, litter and odour) could also imply costs for households or activities located close to the landfill. The negative disamenity impact and the economic costs usually translate in lower property prices adjacent to the landfill. Only a fraction of a high density, low-income residential area to the south east is within 1km from the Olifantsfontein landfill. The impact on Glen Austin’s low density higher value properties is also not expected to be of concern. The disamenity impact could also be significantly reduced with proper management of the site. Possible noise impacts relate to construction and operational activities such as the operation of vehicles and machinery which are anticipated on the dwellings located to the south east of the site that fall within the 1km zone. The area is disturbed from its original characteristics due to considerable soil erosion which is a result of historical excavations, quarrying and illegal sand mining. The disturbed character of the site and the presence of alien invasive species impact on the local sense of place. The height of landfill will be the original ground level, due to the significant excavations from the sand mining activities that have been taking place on the site. Further mitigation of the visual impacts and thus the sense of place would only come into effect once the landfill has been rehabilitated to an end- use which is also visually pleasing. Once a suitable end-use is in place, the impact on the sense of place would thus be low. A Materials Recovery Facility (MRF) will further reduce the amount of waste, open up much needed waste air space in Ekurhuleni and environs and extend the lifetime of the project. The anticipated socio-economic impacts associated with the landfill are of a medium rating. Through good site management (largely required by law) the landfill’s negative socio-economic impacts could be managed to low/medium impacts. The environmental authorisation of the Olifantsfontein landfill is recommended based on the: Relatively low risks of the landfill; Potential for a proper management plan to decrease social risks, as well as Dire need for landfill space for Gauteng’s metros. iii TABLE OF CONTENTS 1.
