GAZETTE NOTICE NO. 1937

Pursuant to Regulation 21 of the Environmental Managenient..and Co-ordination (Impact Assessment and Audit) Regulations, 203, the National OnViroement Management Authority (NEMA) has received an Environmental Impact Assessment Study Report for the above ProPosedmoject. The proponent, Behan Desalination Company Limited, is proposing to establish a new Sea Water Reverse Osmosis (switt) desalination plant with capacity to produce potable quality water at a rate of 100million litres per day (MLD) and the expected annual average availability of 95%. The plant will be located on Mtwapa Creek within the Shinto La Tewa Secondary School compound in Mombasa County 04 libinetiff.lited.bived Row the sohea T lat-Projeect wilt be developed under a Build Operate Own qua, Tatuaffia scheme (BOOT), comprising engineering, procurement and construction (EPC) and Operation Service for a period of twenty-five Years for the Mombasa Seawater Reverse Osmosis Dennis** Plant. The project comprises of seawater intake structure of indicative Length of 70m, diameter 1600 mw and made of GRP pipe and offshore pipeline to the plant; Onshore: intake pulping station, reverse osmosis desalination plant Capacity 100 MLOand.Power requirement of 18 MW to be sourced from existing 132KV Power Lines (National Grid); 1000mm diameter GRP pipe for the discharge of coming from the reject of the Reverse Osmosis system in Own** Area to the Intake area, parallel to the on-shore intake pipe** reaching and connecting to the off-shore reject pipe. The length of thefoipa is Wound 1700 meters; Product Water Transfer Pipeline to city approximately 20 km to the nearest tank of MOmbasa Waler lit Sewerage CoMpany large pipe.

Impacts Interference with long-term regional goals for growth control Proposed Mitigation Measures • Siting of plants near existing seawater intake facilities (e.g., intake pipelines or seawater wells). • Siting of plants near existing energy sources and distribution systems. • Siting of plants near existing fresh water distribution mains to distribute the product water. Sizing of plant capacity to be commensurate with the planned level of development. Assessment of the long-term growth-inducing impacts of proposals for long-term projects and for projects that are intended to be temporary, but may become permanent in the future. Careful siting, planning and design of the development to ensure that it is sympathetic to its surroundings. Preservation of scenic views and valued features. Compensation for the loss of landscape resources example mature vegetation by replacing with an equivalent resource example planting new trees. Proposed Mitigation Measures • Provide workers with protection noise dampening technologies. • Inform nearby houses. • Avoid work during night hours. • Provide workers with protection noise dampening technologies. • Inform nearby houses. • Pumps located indoors, or supplied with soundproof or sheaths to absorb noise. • Sea water quality testing at regular intervals. • Addition of anti-scaling or acid medication suppresses fouling • Soil/site inspection before plant construction. • Install waste water treatment proper management for collection and treatment.

The top of outfall diffuser should be placed well below the sea surface so that it will not cause obstruction for the movement of any boat and crafts. • A marker buoy placed close to intake and outfall will help boats to avoid while enroute. • The pipelines should be buried or allowed for natural burial in the creek floor, so that it will not cause any hindrance to fishing and navigation. Possibility of • Protect work zones with portable scaffold accidents sheets. • Provide proper support for trench sides to protect against their collapse.
