BOMO EDITH EDNA MOLEWA MINISTER OF WATER AND ENVIRONMENTAL AFFAIRS STAATSKOERANT, 2 MEI 2014 No. 37603 3 This gazette is also available free online at www.gpwonline.co.za GOVERNMENT NOTICE DEPARTMENT OF ENVIRONMENTAL AFFAIRS No. 331 2 May 2014 SCHEDULE 1. Definitions In these norms and standards, unless the context indicates otherwise, word or expression that is defined in the National Environmental Management: Waste Act, 2008 (Act No. 59 of 2008) and the National Environmental Management Act, 1998, has the same meaning "Contaminant" means any substance present in an environmental medium at concentrations in excess of natural background concentrations that has a potential to cause harm to human health or the environment; "Informal Residential" means an unplanned settlement on land which has not been zoned as a residential consisting mainly of makeshift structure not erected according to approved architectural plans; "Remediation" means the management of a contaminated site to prevent, minimise, or mitigate harm to human health or the environment; "Soil Screening Value 1" means soil quality values that are protective of both human health and eco toxicological risk for multi-exposure pathways, inclusive of contaminant migration to the water resource; "Soil Screening Value 2" means soil quality values that are protective of risk to human health in the absence of a water resource; "Standard Residential" means settlement that is formally zoned and serviced, and generally developed according to approved building plans, including land parcels such as plots or erven. 4 No. 37603 GOVERNMENT GAZETTE, 2 MAY 2014 This gazette is also available free online at www.gpwonline.co.za 2. Purpose The purpose of these norms and standards is to (a) provide a uniform national approach to determine the contamination status of an investigation area; (b) limit uncertainties about the most appropriate criteria and method to apply in the assessment of contaminated land; and (c) provide minimum standards for assessing necessary environmental protection measures for remediation activities. 3. Application The requirements set out in these norms and standards apply to an owner of land or any person who undertakes site assessment and remediation activity in terms of the National Environmental Management: Waste Act, 2008 (Act No. 59 of 2008). 4. Scope of this Norms and Standards (1) These norms and standards must be used for the screening of a site after a site assessment report is required as a result of declaration of an investigation area as contemplated in section 36 of the National Environmental Management Act, 2008 (Act No. 59 of 2008). (2) Where a contaminant is not listed in Table 1 or Table 2, values which are scientifically validated for the contaminants of interest may be used. (3) The Soil Screening Values in Table 1 and Table 2 must not be seen as (i) absolute minimum values; or (ii) default remediation values.
