GAZETTE NOTICE NO. 94

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 put up a cement intergrated plant for clinker production, grinding cement raw materials inputs ( limestone, volcanic ash, alumino-silicate, iron oxide, gypsum) and other additives to produce 1.2 million tonnes per annum Portland cement that will be located at Pingilikani, Chonyi Area, Chasimba Location, Kilifi South Sub-County in Kilifi County. The following are the anticipated impacts and proposed mitigation measures: Potential Impacts Proposed Mitigation Measures Noise pollution • Choosing quieter machinery provided with efficient silencers/ noise reduction devices. • Development of a green belt in the buffer zone, which acts as a barrier to noise reduction. • Confining noise by isolating the source. • Provide the workers with proper PPEs to minimize occupational noise exposure. • Developing and implementing an effective noise control and hearing conservation program. • Properly maintain the noise-generating pieces of machinery. • Posting notices and signs in noisy areas. • Educating all workers on the importance of making correct use of PPE provided to protect them against high noise levels. • Carrying out an audiometric test by a designated medical practitioner to all workers exposed to noise levels above 85dB(A). Particulate matter (PM) • Fabric bag filters based on the most modern technology to be installed to ensure that the dust emissions are within the prescribed limits and lower than 25mg/Nm3, which is compatible with the best international standards. • Mechanical collectors, dust cyclones. • Electrostatic precipitators. • Particulate scrubbers. • Comply with Air Quality Regulations (2014) and Public Health Act provisions. • Workers to be provided with PPE. • Use of vertical roller mill technology. • Use of air-conditioned, closed cabins. • Dust extraction and recycling systems. • Dust generating material will be cleaned up and removed immediately. • Damping on intervals. • Covering stored raw material. • Enforcement of onsite speed limits. • Water sprinkling on the road during dry wind periods, using a water tanker spillage from the loaded trucks. • Plant dust-catching trees and species to act as efficient biological filters. Greenbelt development reduces fugitive dust and also Potential Impacts Proposed Mitigation Measures checks runoff, and enhances the aesthetic beauty of an area. • Ensure all trucks and machinery are in good serviceable condition. • Design and maintain safe systems of work and pollution prevention measures. • Ventilation at the workplace to be sufficient. 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. • SOx gas is absorbed by Alkali limestone. material in preheater and kiln. NOx emissions • Low NOx burner. • Ultimate Continuous Combustion Technology. • Selective Catalytic reduction SRC. • Selective Non-Catalytic reduction SRC. • Exhaust gas recirculation. • NOx scrubbers. • Catalytic converters. • Oxygen control (decrease), indirect firing. CO Emission • UC3-Ultimate Cell continuous combustion technology. • Good combustion practice, excess air (increase). • Raw material substitution. • Pre-processing system design and mixing air fan. • Proper maintenance of vehicles and other oil- operated equipment. Un-roadworthy vehicles not be allowed into the mine area. CO2 Emission • UC3-Ultimate Cell continuous combustion technology. • Suitable green belt development and production of cement. • Improved thermal efficiency (Thermal oxidizers). • Improved electrical efficiency. • Raw material substitution. • Substitution of clinker in the cement production process. Impacts on land topography • Provide measures for long-term runoff and soil erosion control. • Revegetate the land with indigenous plant species. • Backfill and levelling the open pits with topsoil and rock debris. • Landscaping to leave a final landform visually compatible with the surrounding natural landscapes. • Provide a buffer zone between the project site, road, and human settlements. 28 28 Potential Impacts Proposed Mitigation Measures • The Proponent will use the topsoil generated during the foundation excavation for plantation on bare land. • Paving walkways. • Provide a buffer zone between the site, road, and homesteads. Impacts on drainage and land use pattern • No river passes the site area; hence no eminent diversion of drainage patterns. • Minimize surface runoff by minimizing the area of impervious surfaces. • Install oil water separators and grease traps at refueling facilities. • Construct a water reservoir for the communities. • The Proponent will take utmost care to ensure the survival and growth of existing trees in the area and plant drought-resistant and fast- growing trees in the no-tree land to form a wide green belt all around the mine area. Impact on biodiversity • There is no forest zone near or in the proposed project site. • The development activity will progress on bare land devoid of thick vegetation and associated flora and fauna. Hence, no significant impact on flora and fauna is envisaged. • Landscaping and tree plantation programs will continue to protect biodiversity. Emphasis will be given to local species and plants of economic importance. • Separate conservation plans have been prepared to preserve the biodiversity that, including relocating the species to the Arab Sokoke Forest. • Any soil generated during foundation excavations will be stacked and used for progressive plantation within the project and along the buffer zone. • Develop a site restoration plan to address interim and final reclamation requirements and identify vegetation, soil stabilization, and erosion reduction measures. • Conserving biodiversity species by organizing awareness campaigns and vigilance programs through ensuring dust control measures are enforced in compliance with air quality regulations. • The community’s involvement in the conservation program. Solid waste management and disposal • Waste disposal as provided for in the Environmental Management and Co- ordination (Waste Management) Regulations, 2006. • Traditionally, the proposed operation of the plant is very efficient and does not generate process solid waste. • Recycle and reuse. • Segregate for appropriate disposal. • Process and technological improvement to minimize waste generations. • Material substitution. • Provide appropriate waste handling receptacles. Potential Impacts Proposed Mitigation Measures • Safe disposal of solid waste. • Provide proper sanitary facilities for the workers. Storm water • Sludge from storm water catchments or collection and treatment systems may contain elevated levels of pollutants and will be disposed of in compliance with the Environmental Management and Co- ordination (Water Quality) Regulations, 2006. • Minimize surface runoff (by minimizing the area of impervious surfaces), and the peak discharge rate will be reduced (by using vegetated swales and retention ponds). • The proponent will prevent surface runoff from the plant or potential sources of contamination. • Where storm water treatment is deemed necessary to protect the quality of receiving water bodies, priority will be given to managing and treating the first flush of storm water runoff where the majority of potential contaminants tend to be present. • When water quality criteria allow, storm water will be managed as a resource, either for groundwater recharge or for meeting water needs at the facility. • Oil-water separators and grease traps will be installed and maintained as appropriate at refueling facilities, workshops, parking areas, fuel storage, and containment areas. • Separate Storm water from sanitary wastewater and wastewater streams to reduce the volume of wastewater to be treated before discharge. Waste water related pollution and sanitation management • Segregation and pre-treatment of oil and grease-containing effluents (use of a grease trap) before discharge into the environment. • Treatment to meet national standards for sanitary wastewater discharges. • Sewage from the office blocks to be discharged to either a bio septic system or where the land is used as part of the treatment system, treatment to meet Environmental Management and Co-ordination (Water Quality) Regulations, 2006, standards for sanitary wastewater discharges. Impact on water quality-surface and underground water quality • Mashujaa Cement PLC will restrict Development activities to the layer above the groundwater table. • Cement production process does not produce effluent discharge.
