A part of these proceeds are to cover eligible payments under the Contract for Consultancy Services for the Geometric and Detailed Engineering Design of the Existing Apron and Taxiways at Zanzibar Airport. The Ministry of Communications and Transport in Zanzibar (MOCT) commissioned Sir Frederick Snow (International) Limited on 8 April 2010 to undertake the consultancy commission and to carry out an Environmental Impact Assessment as part of the tasks to be completed. As a first stage in the implementation of overall development of the airside infrastructure at Zanzibar Airport it is proposed that the initial works shall comprise the Rehabilitation of the Existing Apron and Taxiways and that proposed extensions to these facilities shall be undertaken at a later date. The Consultant shall prepare an Environmental Impact Assessment (EIA) and Environmental Mitigation Plan (EMP) based on this initial phase of the proposed works which only involves the Rehabilitation of Existing Apron and Taxiways. Environmental Impact Assessment Process The Environmental Impact Assessment was undertaken following the environmental assessment procedures of Tanzania based upon the Environmental Impact Assessment and Audit Regulations (2005) and the Environmental Management for Sustainable Development Act of Zanzibar (1996) which categorise the construction, expansion or rehabilitation of airports and their ancillary facilities as projects for which a full Environmental Impact Assessment is mandatory. Project Description The airport is located about 7 km south of Zanzibar Town approximately midway along the west coast of the island at latitude of 06.13 degrees south and 39.13 degrees east, and has an elevation of 16.5 m. The general topography of this part of the Island is very flat and well suited for airport operations. The airport lies between two main roads to the east and to the west, both connecting to Zanzibar Town. The first is from Chukwani and the second is from Fumba. Coconut palms, baobab and tamarisk trees are found in the vicinity of these main roads, together with collections of residential areas. Near the airport ___________________________________________________________________________________________________________________i The United Republic of Tanzania Ministry of Communications and Transport Rehabilitation of Zanzibar Airport Apron and Taxiways ENVIRONMENTAL IMPACT ASSESSMENT _______________________________________________________________________________________________________ there are small scattered fields where cassava and other ground fruits are cultivated. The southern approach corridor to the airport runway is free of higher vegetation because of air safety requirements. The airport comprises a single 3022 x 45m width runway, taxiways and apron, all of bitumen standards, plus a terminal building, control tower and other associated facilities. Recently completed work at the airport involves the Rehabilitation and Extension of the Existing Runway by 565 metres. Stakeholder Engagement Stakeholders to the project were involved in the preliminary studies through one to one consultation with government officials and community representatives from Chukwani Ward. Chukwani residents were very eager to know when the construction of the proposed rehabilitation of the existing apron and taxiways will start and whether there are any implications for their land. Among the issues raised, the following statements represent the position regarding their main concerns: • Land Acquisition: No land areas outside of the current airport boundary are to be acquired for this proposed project. The extent of the proposed works is restricted to the Rehabilitation of the Existing Apron and Taxiways plus associated facilities such as surface water outfalls and power supplies for aircraft ground lighting • Compensation Rates: These are not applicable as there are no requirements to acquire any land, buildings, crops or other facilities in connection with the proposed extent of works which are to be undertaken wholly within the current airport boundary. • Compensation Period: The subject of compensation and period of payment is similarly not applicable in connection with the proposed extent of works which are to be undertaken wholly within the current airport boundary and involve the Rehabilitation of the Existing Apron and Taxiways • Communication: A direct line of communication between stakeholders and the Airport Authority is required so that any issues that arise can be promptly and efficiently dealt with. ___________________________________________________________________________________________________________________ii The United Republic of Tanzania Ministry of Communications and Transport Rehabilitation of Zanzibar Airport Apron and Taxiways ENVIRONMENTAL IMPACT ASSESSMENT _______________________________________________________________________________________________________ ORGANISATIONS INVOLVED IN THE ENVIRONMENTAL IMPACT ASSESSMENT Developer: The Developer of the project is the Revolutionary Government of Zanzibar, represented by the Director of Civil Aviation Consultants: Ministry of Communication and Transport commissioned M/S Sir Frederick Snow (International) Limited of the United Kingdom to undertake Detailed Engineering Design, Preparation of Tender Documents and Environmental and Social Impact Assessments for the Rehabilitation of the Existing Apron and Taxiways at Zanzibar Airport. An experienced team was put together by the Consultant to undertake the study, including Eng. Jones Lukaza (Technical aspects, Environmental Engineering and Monitoring Plans), Ms. Martha Kamuzora (Environmental Engineer) and Mr. Bashir Abdul (Socio- economic aspects). Parties Consulted: • Project Proponent – Zanzibar Airport Management Team: Acting Technical Manager. • Ministry of Water, Construction, Energy, Lands and Environment: Environmental Officer • Chukwani Residents • Chukwani Ward Leader (Shea) Environmental and Social Impacts The ESIA team of experts considered all aspects of the project that could cause either environmental or socio-economic changes. They evaluated the significance of each aspect of the project using defined criteria which took into account the scale, extent and duration of each point, the potential to implement mitigation measures and controls, and the likelihood and timescale of environmental recovery. The team also took into account national and international policy, legislative and administrative frameworks, standards and guidelines. The rehabilitation of the apron and taxiways is viewed as positive with regard to general development in Zanzibar and Tanzania. Positive outcomes of the project include improved air transport, increase in ___________________________________________________________________________________________________________________iii The United Republic of Tanzania Ministry of Communications and Transport Rehabilitation of Zanzibar Airport Apron and Taxiways ENVIRONMENTAL IMPACT ASSESSMENT _______________________________________________________________________________________________________ tourism and improvements to the socio-economy of the area. Negative outcomes of the project include depletion of natural resources, contamination and impaired quality of water and land, visual impacts, public health hazards and health hazards or disturbances to offsite receptors. However, many of the negative impacts can be avoided or minimised to acceptable levels and positive impacts and benefits can be enhanced by adopting good engineering practices and appropriate mitigation measures during design, construction and use of the airport. Mitigation of Impacts The following is a summary of environmental impacts and their proposed mitigation measures: Aspect Project Phase Potential Impacts Mitigation/ Management Option 1. Localized impact that is mainly occupational, so provide hearing protection to construction crews Increase in noise and vibration Mobilisation and 2. Adherence to machinery maintenance schedule Air quality
