Digital Terrestrial Television Infrastructure Rollout Environmental Impact Assessment - Aussenkehr - 1 1 ENVIRONMENTAL IMPACT ASSESSMENT (EIA): AUSSENKEHR 1.1 INTRODUCTION Aussenkehr is a small agricultural settlement, 50 km west of Noordoewer on the banks of the Orange River, which forms the border between Namibia and South Africa. The settlement is home mainly to workers of the neighbouring grape farms but also include a number of lodges, viticultural farms and two schools (a kindergarten and Aussenkehr Primary School). It is nonetheless especially the array of small reed houses in which the lower income group lives that contribute to the character of the settlement. 1.2 RATIONALE FOR SITE Infrastructure development is a serious concern in the expansion of Aussenkehr and various complaints have in recent years been published regarding the poor living conditions of the residents (1NPC, 2007). It is for this reason that the Karas Regional Council is in the process of developing a new town at Aussenkehr. As part of this infrastructure development process the NBC is now intending on constructing NBC infrastructure in Aussenkehr. It is predicted that a NBC transmitter in close proximity of the settlement will provide coverage to the largest part of the surrounding area (Figure 1). 1 National Planning Commision (NPC). (2007).

Digital Terrestrial Television Infrastructure Rollout – NBC EIA - Aussenkehr August 2013 2 Figure 1: Predicted coverage of a NBC transmitter in Aussenkehr. 1.3 SITE DESCRIPTION Aussenkehr is situated in an open valley that slightly slopes towards the Orange River whilst being surrounded by mountains on all sides. Various small drainage lines flow through the valley towards the River and in the harsh climatic conditions associated with the area it is not surprising to find that vegetation is scarce and restricted to these drainage lines. The area is known to have a rich diversity of bird species particularly closer to the River and due to the rocky nature of the surrounding areas; it is likely that various reptile species also occur. During the site visit a possible location for the erection of the NBC transmitters were investigated. The proposed position in relation to other landmarks, are indicated in Figure 2: Digital Terrestrial Television Infrastructure Rollout – NBC EIA - Aussenkehr August 2013 3 Figure 2: Position of the proposed site investigated for the construction of the NBC mast at Aussenkehr. An Assessment form was completed during the site visit based on the visual observations and technical information available. Below (in Table 1) follows the completed assessment form for Aussenkehr, highlighting information for the proposed position: Digital Terrestrial Television Infrastructure Rollout – NBC EIA - Aussenkehr August 2013 4 Table 1: Assessment form for Aussenkehr site.

Ephraim, at his office in Noordoewer. In addition to this, a fax containing the details of the public meetings was sent to his offices on the 1st of September 2011. Other identified possible Interested and Affected Parties (I&APs) included the principals of the two schools, namely Aussenkehr Academy and Aussenkehr Primary School, who were contacted telephonically and provided with a Background Information Document and an opportunity to comment on the proposed project in an email. The consulted stakeholders as well as their capacity and the comments received, are contained in Table 2 below: Table 2: Capacity of and comments received from the consulted stakeholders in Aussenkehr.

Principal Aussenkehr Academy Principal Fax (063) 297-100 Because consultation was done in 2010 and many officials and local I&APs are likely to have changed throughout the course of the project, consultation could become out dated. The aim is therefore to repeat the consultation process just before commencing with the construction phase.

IDENTIFICATION OF IMPACTS ASSOCIATED WITH THE PROPOSED SITE It is necessary to determine whether the proposed site requires a full environmental assessment with specialist input or whether the available information is sufficient to draw conclusions regarding the true sensitivity of the site. To do this a screening process is applied to the potential impacts of the project (Figure 4). Do we have sufficient information to address the issue? YES NO Can issue be addressed through the Specialist input required implementation of a generic EMP? Full EIA YES NO Issues addressed in An Additional Appendix is required Generic EMP to the Generic EMP that contains site specific mitigations. Figure 4: Questions used to screen the potential impacts associated with the development. The Aussenkehr site follows the indicated “orange” route which implies that most issues can sufficiently be addressed through a Generic EMP, but that an additional appendix is required to address some site specific issues.
