Tshedza Mining Resources (second respondent) applied for an integrated water use licence on 8 November 2012 under the National Water Act 36 of 1998 for its open-cast coal mining operations. The Department of Water and Sanitation (DWS, first respondent) returned the application requesting more information including public participation. An Environmental Assessment Practitioner (EAP) acting for Tshedza Mining issued notices in August and September 2013 inviting comments. The appellants (Evander Gold Mines and Evander Gold Estates) submitted a detailed objection letter on 13 December 2013 to the EAP raising serious concerns about groundwater impacts and post-closure water pollution risks. The EAP failed to include this letter in the water use licence application submitted to DWS, though it was included in the environmental authorisation application to the Department of Environmental Affairs. On 27 January 2015, the appellants wrote directly to the Director-General objecting to the licence. Three days later, on 30 January 2015, the DG decided to grant the licence (issued 23 February 2015). The appellants appealed to the Water Tribunal on 19 March 2015. Both DWS and Tshedza Mining raised a preliminary objection that the appellants lacked standing because they had not timeously lodged a written objection as required by section 148(1)(f) of the National Water Act.
