Under the Environmental Management Act (Act 7 of 2007) section 27 the activity described as "energy distribution, transmission and generation" requires an Environmental Clearance Certificate (ECC) as it is a listed activity. In 2020 NamPower obtained the Environmental Clearance Certificate for the management and operation of the 66kV Osona - Okahandja transmission line. NamPower would therefore like to apply for the renewal of the ECC for 66kV Osona - Okahandja line in order to comply with the Environmental Management Act (Act 7 of 2007) and its regulations. This ECC also includes Okahandja Substation and Ongeama Substation. The 66kV Osona - Okahandja powerline was constructed in 1978 and is 24.8 km in length. This powerline run from Osona substation to Okahandja substation in Otjozondjupa Region. Okahandja and Ongeama Substations cover a footprint of about 1 415 m² and 563² respectively. The powerline has towers made of wooden (kamarad) 5 poles structures. Figure 1 shows the locality map for the 66kV Osona - Okahandja transmission line.
