GAZETTE NOTICE NO. 14665

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, Mombasa Cement Limited (Vipingo Unit), proposes to set up a Captive Power Plant (CPP) using Circulating Fluidized Bed Combustion (CFBC) Boiler technology to generate 10MW of electricity from a fuel mix consisting of bituminous coal with a heat value of 5600Kcal/kg cashew nut shells, wood chips and briquettes on plot L.r. No. MN/III/291/2 and MN/III/4391 within an existing MCL Vipingo cement factory in Kikambala Division, Kilifi South Sub-County, Kilifi County. The following are the anticipated impacts and proposed mitigation measures: Potential Negative Impact Proposed Mitigation Measure Noise and vibration disturbance • Use noise reduction technologies such as acoustic covers Training and education on risks of noise exposure. • Appropriate use of Personal Protective Equipment (PPEs) Maintenance and inspections of machinery and equipment. • Technical controls to reduce noise at the source. • Limit workers' exposure time and rotation to less noisy tasks. Fugitive dust • Limit amount of exposed soil. • Construct wind barriers or install cover tarps. • Apply water to suppress dust. • Apply chemical dust suppressants. • Use vacuum controls on equipment to keep surfaces clean of debris. • Apply soil stabilizers. • Establish vegetative cover. Injuries and accidents • Always utilize safety gear (PPEs). • Timely and proper equipment service and maintenance. • Develop and follow safety protocols while on site. • Schedule regular safety meetings. • Take regular breaks. • sufficient signage to warn of dangers and hazards. • Conduct worksite inspections daily to identify any potential dangers or hazards. • Mandatory safety training for all employees. • Proper material storage and handling. 9th October, 2025 THE KENYA GAZETTE Potential Negative Impact Proposed Mitigation Measure • Fall protection protocols and fall protection equipment . Waste generation • Proper planning to reduce generation of construction waste. • Effective material management to reduce generation of construction waste. • Recycling materials such as concrete, steel, and wood. • Implementing composting as a waste reduction strategy. • Purchasing materials in bulk to reduce waste from individually packaged materials Emission of toxic pollutants • Capture and recover all flue gases and waste heat generated and reuse it to generate electricity. • Deploy emission control technologies such as electrostatic precipitators, scrubbers, and bag-house filters. • Operate at optimal temperature to achieve complete combustion. • Minimize flue gasses emission by appropriate fuel selection, burner modifications, appropriate air firing, flue gas recirculation and constant water stream injection. Increase in demand of process water Waste generation impacts • Increase intercepted natural groundwater recharge through increase in vegetation cover. • Increase induced groundwater recharge using treated wastewater • Increase artificial aquifer recharge • Reduce water abstraction by reuse process after cooling in cooling tower • Fix any leakages in the system to eliminate steam and water loss. Bed agglomeration and de-fluidization • Decrease the operating temperature of the reactor. • Increase the gas velocity. • Replace the bed material. • Pre-treatment of solid fuels to remove alkali metals • Use bed additives such as kaolin, dolomite and olivine. • Replace bed material. Boiler explosion • Regular boiler inspection and maintenance. • Have robust safety protocols in place. • Inspection of pump inlets and fixing loose connections. • Avoid ash accumulation in the furnace. • Regular checking of safety valves. Positive pressure boiler risks • Ensure no blockage of fuel due to ash accumulation. • Ensure no air leakage from boiler. Potential Negative Impact Proposed Mitigation Measure • Ensure sufficient air volume and pressure of induced draft fan A full report of the proposed project is available for inspection during working hours at: (a) Principal Secretary, Ministry of Environment, Climate Change and Forestry, NHIF Building, 12th Floor, Ragati Road, Upper Hill, Upper Hill, P.O.
