August 2010 448848the effect of keeping polluted air close to the surface, so that winter air quality over theHighveld is generally poor.Site DescriptionAll sources of atmospheric emissions near the site were identified with potential pollutantslisted. Domestic fuel burning from the informal settlements surrounding the site is likely to bethe main contributing sources in the area together with Cape Gate and Arcelor MittalVanderbijlpark.SensitivitiesThere are no foreseen climatic sensitivities associated with the site or the proposed activity.7.1.2 Geology and SoilsMethodology and Data SourcesGeologyA desktop screening assessment, using a GIS tool was undertaken of the geologicalenvironment. The geological data was taken from the Environmental Potential Atlas(ENPAT) data from the DEA.Seventeen test pits were excavated across the site for the proposed extension of theBoitshepi Waste Disposal Site using a Cat 428 backactor supplied by Lichenry Constructionfrom Vereeniging. The test pits were entered by a registered professional engineeringgeologist who described the soil and bedrock formations in terms of the methods advocatedby Jennings et al (1973) namely, moisture condition, colour, soil consistency, soil structure,soil type and origin (MCCSSO). Disturbed representative soil samples were recovered fromthe test pits and submitted to SNALAB’s commercial soils laboratory in Pretoria for testingand identification, three water samples were submitted to RHC’s chemical laboratory inPretoria for analysis. The detailed descriptions of the test pit profiles are provided on theSoil Profile Sheets of the Geotechnical Report attached in Appendix C4.SoilsA site visit was conducted by the specialist on the 17 th of February 2010. Soils were augeredat 150m intervals where possible along the proposed extension alternatives using a 150 mmbucket auger, up to refusal or 1.2 m. Soils were identified according to the Soil Classification;a taxonomic system for South Africa (Memoirs on the Natural Resources of South Africa, no.15, 1991). The following soil characteristics were documented:• Soil horizons;• Soil colour;ZITHOLELE CONSULTING
