GAZETTE NOTICE NO. 76

PURSUANT to section 59 of the Environmental Management and Co-ordination Act, 1999, the National Environment Management Authority (NEMA) has received an Environmental Impact Assessment Study Report for the above proposed project. The proponent, Kaishan Terra Green Ammonia Limited, proposes to supply geothermal steam from existing wells to Kaishan Terra Green Ammonia Limited (Kenya)’s 480kta Green Fertilizer Project. The proposed project will involve the establishment of a Green Ammonia Fertilizer Plant and associated 165.4-megawatt geothermal power plant (147.0 MW Central Power Plant and 17.4 MW Pad 49 wellhead power plant). The project will also include auxiliary facilities which shall include an 11Kv TO 220kV substation to be located in close proximity to the Central Power Plant with two main transformers each with a capacity of 180 MVA, a distribution control system and a service Centre located at the Central Power Plant, as well as an overhead 220kV high-voltage transmission line of about 6km, 11kV transmission line of approximately 4.5km and steam pipelines from the existing geothermal wells in Olkaria to the project’s power plant, cooling water station and high-purity water station to be located at the fertilizer plant. The green fertilizer manufacturing plant will utilize power and heat from the geothermal power plants in its production process in Olkaria, Naivasha, Nakuru County The following are the anticipated impacts and proposed mitigation measures: Impacts Mitigation Measures Impacts on Fauna • Implement a Park Interface Management Plan covering traffic routing, shielded lighting, boundary noise limits and spill prevention at the park edge. • Fence the entire plants footprint. • Minimize artificial lighting at night to reduce disturbance, especially to nocturnal species. Air quality • Water unpaved sites access roads and work areas routinely during dry and windy weather conditions. • Cover loose material transportation trucks and avoid overfilling. • Carry out weekly visible dust checks and conduct quarterly boundary particulate matter monitoring. • Reinject geothermal fluids to eliminate surface discharge of hydrogen sulphide. • Extract hydrogen sulphide from condensers and either reinject it or treat it with abatement when concentrations exceed the threshold. • Operate continuous hydrogen sulphide monitoring. • Maintain gas handling systems that control hydrogen sulphide and ammonia and capture urea dust through enclosures and filters • Conduct an annual ambient air quality survey for hydrogen sulphide. • Establish and implement a leak detection and repair program. • Inspect ammonia lines valves and tanks regularly using portable detectors and ensure timely repair. • Connect all ammonia vents and relief valves to a flare or scrubber. • Conduct annual third-party stack emissions testing for ammonia, particulate matter and oxides of nitrogen. • Design drilling towers with controlled airflow. Noise and vibration • Maintain acoustic enclosures, silencers and low noise equipment and keep boundary noise within acceptable limits. • Fit mufflers and silencers on equipment e.g. generators, compressors, and heavy equipment. • Restrict high-noise activities to daytime hours and ensure local communities are notified in advance of any scheduled noisy activities. • Install and maintain acoustic insulation around the turbine hall and compressor rooms. • Regular noise monitoring. Water Consumption • Implement a water efficiency plan that reuses cooling tower blowdown. • Install Water use meters in each unit and prepare a monthly water balance to detect leaks and excessive consumption. Water quality degradation • Install silt fences and sediment traps before earthworks begin. • Construct temporary drains that divert storm water away from disturbed areas. • Store fuels, oils and chemicals in banded and roofed areas with impermeable floor. 2nd January, 2026 THE KENYA GAZETTE Impacts Mitigation Measures • Manage wastewater in line with the Environmental Management and Coordination (Water Quality) Regulations, 2024. Wastewater generation • Treat all process wastewater to ensure ammonia and urea condensate are stripped and reused. • Install groundwater monitoring wells around the site and sample them twice a year with a focus on storage areas and reinjection wells. Generation of Brine • Reinject the brine water into the reinjection wells. Generation of Solid waste • Develop and implement an integrated waste management plan. • Segregate waste at the point of generation. • Maximize recycling of waste materials (metals, wood and plastics) as appropriate. • Store hazardous waste in a banded and covered holding area. • Track waste generation and disposal. Occupational health & safety • Prepare and implement a health and safety Management Plan. • Maintain a process safety management system. • Provide and ensure appropriate use of Personal Protective Equipment (PPE) by all workers. • Maintain a first aid post with trained first aiders on every shift. • Run health programs that include annual medical checks and wellness initiatives. • Conduct daily toolbox talks and weekly safety inspections. • Develop and implement a Chemical Management Plan (CMP). Community Health and Safety • Design all infrastructure to meet or exceed safety standards. • Post clear multilingual warning signs along the right of way. • Maintain robust site security including perimeter fencing surveillance and patrols. • Continue community air quality monitoring for hydrogen sulphide or other emissions. Social Risks • Implement a worker influx and traffic management plan to control workforce movements, road safety, and community interaction. • Enforce a worker Code of Conduct to prevent and address social risks including gender-based violence and harassment. • Develop and implement an emergency preparedness and response plan in coordination with county authorities and neighboring communities.
