Considering the nature of the proposed development and its activities, the EIA has been undertaken in accordance with the requirements of existing national legislations, of which the National Environmental Assessment Policy (1995), the Environmental Management Act (2007) and its regulations of 2012, and other relevant legislations and regulations pertaining to Environmental Assessments and protection of the environment in the Republic of Namibia are considered most important. Some existing international policies are also taken into account and are used as guidelines. Impacts identified from baseline studies, site visits and stakeholder consultation process have been assessed making use of a comprehensive assessment methodology as provided by the Department of Environmental Affairs (DEA) of Namibia. This included looking at impact significance through, its nature, extent, duration, probability and intensity. Major issues or impacts identified are soil, surface and ground water impacts; air quality (including dust pollution); ecological impacts; risk of fires and explosions; hygiene and health impact; heritage impacts; generation of waste; traffic safety, especially during construction; noise pollution; safety and security; and cumulative impacts. These impacts are assessed in each of the three stages of project development namely, construction, operation and decommissioning phases. Socio-economic impacts amongst others include creation of part-time and permanent employment opportunities and economic spin-offs for the local businesses and suppliers. Cumulative impacts expected as a result of the proposed fuel retail facility include, dust and exhaust emissions from vehicles frequenting the facility during all phases of the development, coupled with the existing emissions from vehicles in the surrounding areas, the air quality will be impacted. A slight traffic nuisance might be experienced by motorists using the nearby roads. This will most likely be caused by slow moving vehicles frequenting the construction site. Minor leakages from the operations of the facility may result in a collective long-term significant impact on the groundwater. In general, impacts are expected to be low to medium, mostly short lived and site specific. Mitigation options recommended in the Environmental Management Plan (EMP) will guide and ensure that the impacts of the construction work are minimised. All environmental risks can be minimised and managed through implementation of preventative measures and sound management systems. Environmental audits should be carried out to ensure compliance of the EMP and environmental regulations of Namibia. 1 Environmental Impact Assessment - Proposed Fuel Retail Facility in Khomasdal, Windhoek Matrix Consulting Services TABLE OF CONTENTS EXECUTIVE SUMMARY ..................................................................................................................... 1 GLOSSARY OF TERMS ...................................................................................................................... 5 1.
