GAZETTE NOTICE NO. 9792

PURSUANT to section 59 of the Environmental Management and Co-ordination Act, Cap. 387, the National Environment Management Authority (NEMA) has received an Environmental Impact Assessment Study Report for the above proposed project. The proponent, Rift Valley Development Trust, proposes to develop a special Economic zone (SEZ) comprising of a mixed use development covering a total of 1046 hectares including residential neighborhood, light industrial activities, commercial centers, institutional facilities, recreational infrastructure, associated facilities and amenities located at Nakuru Municipality Block 40/2 (formerly L.R. No. 22771/3) in Nakuru County. The following are the anticipated impacts and proposed mitigation measures: Impacts Mitigation Measures Soil disturbance • Control earthworks and compact loose soils. • Install drainage structures properly. • Landscaping on project completion. • Control and manage excavation activities. • Control activities especially during rainy conditions. • Provide soil erosion control and conservation structures/means where necessary. • Ensure standard appropriate practices on the provided gardens. Changes in land use- extent • Plant vegetation after project completion. • Ensure compliance with existing planning policy. • The project shall be approved by the relevant government bodies before commencement. Changes in hydrology/ impended • Proper Installation of drainage structures. • Install cascades to break the impact of water flowing in the drains. Drainage/deep excavations • Ensure efficiency of drainage structures through proper design and maintenance • Provide gratings to the drainage channels . • A geotechnical survey shall be conducted and the recommendations thereof followed. • There shall be no blasting during excavation. • A methodology for excavation shall be generated as required by NCA prior to excavation. Air pollution • Enclose the site with dust-proof net during construction. • Water should be sprayed during the construction phase of excavated areas during dry conditions. • Control speed and operation of construction vehicles. • Prohibit idling of vehicles. • Ensure sound condition of construction machinery and equipment. • Engage sensitive construction workers. Impacts Mitigation Measures Noise pollution • Erect suitable barriers to control noise. • Sensitize drivers of construction machinery on effects of noise. • Maintain plant equipment (if present). Construction activities to be restricted to daytime. • Workers in the vicinity of or involved in highlevel noise to wear safety and protective gear. Water quality and sewerage infrastructure • The design of the entire sewerage system should consider the estimate discharges from individual sources and the cumulative discharge of the entire project even during peak volumes. • Provide for adequate drainage systems. • Ensure effluents are discharged responsibly to the sewerage system. • Monitor quality of wastewater to ensure compliance with the Environmental Management and Coordination (Water Quality) Regulations, 2024 and other relevant Laws. Oil pollution • Proper storage, handling and disposal of new oil and used oil wastes as per waste regulations. • Maintain plant and equipment to avoid leaks. • Maintenance of construction vehicles should be carried out in the contractor’s yard (off the site). • Provide oil interceptors along the drains leading from car park and potentially oil risk areas. Road safety • Enforce speed limits for construction vehicles especially along roads leading to the site. • Provide bill boards at the site/entrance to notify motorists about the development. Public health, occupational health and safety • Train staff/workers on occupational health and safety. • Provide full protective gear and workmen’s compensation cover in addition to the right. • Tools and operational instructions and manuals during construction. • Adopt sound waste management system to ensure proper solid waste disposal and collection facilities. • Adopt sound housekeeping practices. • Sensitize residents on environmental management. • Design of sewerage system should be as provided in the plans and should be constructed to approved size and design, standard and of approved materials. • Engage the services of qualified personnel and/or ensure training. • Ensure use of standard construction materials and to the specifications. Avoid undesirable, substandard, hazardous or unauthorized materials during construction and maintenance. 26th June, 2026 THE KENYA GAZETTE Impacts Mitigation Measures • Sensitized staff on social/health issues such as drugs • Ensure machinery and equipment servicing and maintenance as per schedules and legal requirements • Post strategically the Factories and Other Places of Work Act Abstract and provide. • Material safety data sheets • Post clear warning signs e.g. ‘No unauthorized use of machines’, ensure there are guards on moving parts etc. • Provide fully equipped First Aid kits and train staff on its use. • Ensure adherence with the legal requirements Factories Act. • Sensitize residents on environmental management. • Ensure Nakuru County Government certifies and issues occupation certificates. Vegetation • Avoid unnecessary removal of vegetation. • Landscaping and planting vegetation in all disturbed areas. Record keeping • Collection and analysis of relevant environmental data of the site. Fire safety and preparedness • Install firefighting equipment as provided elsewhere in the report. • Conduct training on firefighting, evacuation and emergency response. • Sensitize the residents on fire risks i.e., conduct regular fire drills. • Adapt effective emergency response plan. • Maintain/service firefighting machinery regularly. • Provide emergency numbers at strategic points. Water quality • The design of the entire sewerage system should consider the estimate discharges from individual sources and the cumulative discharge of the entire project even during peak volumes. • Provide for adequate drainage system. • Ensure effluents are discharged responsibly to the sewerage system. • Install an oil water interceptor to trap oils that may be present in wastewater. • Apply and obtain an Effluent Discharge License (EDL) for effluent released into the environment. • Monitor quality of wastewater to ensure compliance with the Environmental Management and Coordination (Water Quality) Regulations, 2024 and other relevant Laws. Waste management • During construction phase, designate an area for temporarily holding waste materials. • All wastes should be disposed of in accordance with the Environmental Management and Coordination (Waste Management) Impacts Mitigation Measures • Regulations, 2006 and other relevant Laws. • Segregation of wastes at the source for ease of handling and disposal. • Contract a NEMA licensed waste transporter to transport solid waste from the proposed site during construction and occupation phases. • Sell recyclable waste to recyclers. • Provide bins for temporarily holding waste before collection by licensed transporters during occupation phase. Traffic management • Conduct a traffic Impact Assessment and generate a traffic management plan. • The Traffic management plan should be followed throughout the project cycle. Security and social impacts • Provide security guards, CCTV cameras and other security apparatus during the entire project cycle. • Construction work timings shall only in line with the NEMA licensing conditions.
