GAZETTE NOTICE NO. 1245

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, Athi Water Services Board is proposing to construct sanitary facilities in Oloitokitok Sub-County of Kajiado County. The proposed project intends to construct trunk sewer pipeline of length 6,600m, lateral sewers pipeline of length 8,798m and wastewater treatment plant for Oloitokitok town at Kiwanjani. The following are the anticipated impacts and proposed mitigation measures: Impacts Proposed mitigation measures Vegetation loss due to clearance • Clearance of the site for construction purposes shall be kept to a minimum. • The extent of clearing within the work stations should be clearly marked. • Rehabilitate all disturbed areas through re-vegetation. • Instruct all construction workers to restrict clearing to the marked areas and not to work outside defined work areas. • Avoid cutting indigenous trees and vegetation within the project area. • Integrity of forest resources should be well guarded from the spill-over effects of the project‘activities so as to maintain their functionalities. Risk of invasive species • Raw materials such as sand and rocks should be sourced in areas where there are no alien/ invasive species. • The equipment required for the construction works should be clean and free from alien plants and mud which may contain seeds of alien species. • The foreign workers should be refrained form bring in unauthorized domestic fauna. Noise • Workers within the vicinity of high level noise to be provided with adequate PPE. • No idling of vehicles and machinery if not in use, they should be switched off. • Control speed and noise of construction machinery. • Insulate noisy machines and activities during construction to minimize noise impact to neighbouring community. Air quality • Provide dust masks to workers. • Sprinkle water on the soil during excavation and land filling. • Control speed of working machinery. • Provide dust masks to workers. Water quality • Apply appropriate water quality management procedures to prevent contamination. • Sensible use of agrochemicals to prevent deposition into rivers. • Adhere to Waste Water Regulations of 2006. • Encourage compaction of loose material/soils. • All repairs and maintenance work should be done at the contractor‘s yard. • Develop and implement effluent discharge control plan. Soil erosion • Observe erosion control measures on areas prone to erosion especially steep slopes. • Topsoil should not be used during the construction phase. • There should be intensive re-vegetation on bare grounds after construction. Increased generation of wastes • Observe erosion control measures on areas prone to erosion especially steep slopes. • Topsoil should not be used during the construction phase. • There should be intensive re-vegetation on bare grounds after construction. • All grey water run-off or discharges should be contained and properly channelled away from water sources. Occupational safety and health The contractor should have a comprehensive health and safety policy. Ensure there is compliance to OSHA, 2007. Establish a standard code of practice for the project workers. Install fully equipped first Aid Kits at strategic points at the working. Warning signs/bumps to be erected and/or placed at risky points. Provide adequate emergency procedures for the facility staff; Arrange regular emergency drills for staff.
