GAZETTE NOTICE NO. 1407

Pursuant to Regulation 21 of the Environmental Management and Co-ordination (Impact Assessment and Audit) Regulations, 2003, the National Environment Management Authority (NEMA) has received an Environmental Impact Assessment. Study Report for the above proposed project. The proponent, Northern Water Works Development Agency proposed to construct an earth fill dam. The dam is expected to be a result of excavating 3.7m below the ground and making an embankment of about 2.25m at the hind above the ground. It is expected to be of capacity 647,664 meter cubic submerging an area of 10.7944ha, Chalbi Sub-county, Marsabit County. The following are the anticipated impacts and proposed mitigation measures: Impacts Proposed Mitigation Measures Water resources • Promoting an effective water resource depletion management program. • Initiate afforestation and agro- forestry program for soil and water conservation. • Initiate community capacity building on water management, sanitation, operation and maintenance. • Ensure that environmental flow requirements are met by releasing steady and adequate flow from the dam reservoir. Dust generation • Enclosing demolition sites. • Spraying water on dusty roads. • Covering or enclosing transportation vehicles, controlling the speed of vehicles, and selecting transportation routes to minimize impact on dust sensitive receivers. • Covering or watering open spoil or storage sites. • Minimizing on-site storage time of construction materials. • Ensure no construction using heavy machinery, from 22.00 to 6.00 hrs., near settlements and boarding schools. • Allow for Non-discretionary use of noisy machinery within 50 m of settlements and boarding schools. • Undertake good maintenance and proper operation of construction machinery. • Installation of temporary sound barriers if necessary. • Selection of transport routes for large vehicles to avoid settlements and schools. • Top soils to be stock-piled separately from subsoils. • Top soils to be spread over those areas which can be restored in order to facilitate natural regeneration. • Use protective structures to avoid small-scale landslides where soil erosion potential is high. • Avoid construction during heavy rains. • Planting of conservation vegetation to control erosion and sedimentation.
