GAZETTE NOTICE NO. 6332

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, Mashujaa Cement PLC proposes to construct a cement grinding plant, comprising of the cement grinding area, a raw material area, store, parking, security area, electrical control room, shed for park material, office building and associated amenities on 25th June, 2021 THE KENYA GAZETTE L.R. No. 7885/17, 18, 19 and 20 at Mathatani, Mavoko Sub-county in Machakos County. The following are the anticipated impacts and proposed mitigation measures: Possible Impacts Mitigation Measures Noise pollution • Choosing quieter machinery provided with efficient silencers. • Use of Vertical Roller mill technology. • Confining noise by isolating the source. • Using the equipment having low noise emissions. • Use equipment which is properly fitted with noise reduction devices. • Restrict the operation during the night. • Supply appropriate personal noise protection gear to construction workers. Dust/ air quality • Particulate emission in bulk is not encountered in grinding unit. • Use of Vertical Roller Mill technology. • Fabric filters based on the most modern technology are proposed to be installed to ensure that the dust emissions are within the prescribed limits and lower than 25mg/Nm3, which is compatible to the best international standards. • Use of air–conditioned, closed cabins. • Dust extraction and recycling systems. • Dust and any other material which generate dust will be cleaned up and removed immediately. • Damping on intervals. • Covering stored raw material. Solid waste management and disposal • Traditionally the proposed operation of the plant is very efficient and does not generate/produce solid waste. • Recycle and reuse. • Segregate for appropriate disposal. • Process and technological improvement to minimize waste generations. • Material substitution. • Waste disposal as provided for in the Environmental Management and Co- ordination (Waste Management) Regulations, 2006. • Provide appropriate waste handling receptacles. • Safe disposal of electronic waste. Storm water • Storm water will be separated from process and sanitary wastewater streams. • Minimize runoff. • Runoff will be minimized and the peak discharge rate be reduced. • Use of Oil water separators and grease traps. Effluent treatment and waste management • No effluent produced. Waste water disposal/water pollution • No water pollution. Possible Impacts Mitigation Measures • Water used for cooling purposes. Conflict • Replanting grass, flowers and overall landscaping on exposed areas. • Build temporary drainage channels. Transportation/traffic • Eliminate dust generation. • Damping. • Observance of traffic guidelines. Sulphur (Sox) gases • Fuel substitution (lower total sulfur). • Flue gas desulphurization (FGD). • Wet systems. • Targeted emissions reduction. • Wet scrubbers. • Dry scrubbers. • Raw material alkali/sulfur balance. Nox emissions • Low NOx burner. • Ultimate continuous combustion Technology. • Selective catalytic reduction SRC. • Selective non-catalytic reduction SRC. • Exhaust gas recirculation. • NOx scrubbers. • Catalytic converter. • Oxygen control (decrease), indirect firing. CO emission • UC3-ultimate cell continuous combustion technology. • Good combustion practice, excess air (increase). • Raw material substitution. • Preprocessing system design and mixing air fan. Co2 emission • UC3-Ultimate Cell continuous combustion technology. • Suitable green belt development and production of cement. • Improved thermal efficiency. • Improved electrical efficiency. • Raw material substitution.
