GAZETTE NOTICE NO. 12808

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, Corrugated Sheets Limited proposes to construct and install a steel mill for melting of steel scrap to generate molten metal that is continuously casted to produce billets. The steel mill will have a billet manufacturing plant constisting of an induction melting furnace (scrap, furnace, raw material handling and storage, ferroalloy addition sampling and quality control, slag handling storage and dispatch), continuous billet casting machine and a pollution control systems comprising a systems of movable fume collection hood, cyclone, pipeline, bag house, sanction blower, bag house cleaning system, chimney, liquid metal and ladle. The project will have sanitary facilities, offices, weighbridge and weighbridge house and associated amenities and facilities, on plot L.R.No.24606 at Kokotoni area of Kaliangombe Sub-location, Rabai Sub-county, Kilifi County. The following are the anticipated impacts and proposed mitigation measures: Impacts Proposed Mitigation Measures Solid waste generation • Ensure that all generated waste will be managed and disposed as provided for in the Impacts Proposed Mitigation Measures Sustainable Waste Management Act, 2022 and the Environmental Management and Co- ordination (Waste Management) Regulations, 2006. • Ensure that all generated steel scrap to be collected and safely kept at a designated location on site from where it will later be recovered for onsite recycling to produce billets. • Ensure that excavated overburden (soil and rock material) to be reused in landscaping within the CSL RSD and also in the rehabilitation of quarry pits of the adjacent sister company Kavee Quarries Limited. • Segregate non-hazardous waste into organic and non- organic fractions. • Provide facilities that are properly labeled and color-coded receptacles, bins, containers and bags for the placement of the segregated waste. • Ensure any hazardous waste generated is handled and managed as prescribed in the Environmental Management and Co- ordination Act, 1999 (No. 8 of 1999) and dispose of the hazardous waste in a facility provided by the County Government of Kilifi or the Authority. Injuries and accidents • Register the workplace as per the provisions of the Occupational Safety and Health Act, 2007. • Hire well trained and experienced plant and equipment operators. • Ensure hired workers are first trained on the appropriate use of the provided PPEs. • Ensure all workers and visitors use the provided PPEs appropriately. • Ensure that tools and equipment provided for use are well serviced and maintained. • Ensure there is a fully equipped first aid station at various sections of the steel mill. • Develop and document an emergency evacuation plan for the workplace. • Maintain a well-stocked first aid box at the workplace. Air pollution • Install a functional and efficient air pollution control system (fume extraction system) consisting of movable fume collection hood, pipeline, cyclone, bag house, sanction blower, bag house cleaning system, chimney, liquid metal and ladle a system that will be working together to ensure air quality standards prescribed in the Environmental Management and Co-ordination (Air Quality) Regulations, 2014 are strictly adhered to. • Carry out quarterly (every three months) monitoring of local air quality as provided for in the Environmental Management and Co- ordination (Air Quality) Regulations, 2014. • Monitor noise and vibrations as provided for in the Environmental Management and Co- ordination ((Noise and Excessive Vibration Pollution) (Control) Regulations. Noxious odours and dioxins in exhaust gas • Increase Electric Arc Furnace (EAF) temperature to achieve complete combustion of organic matter during the low temperature phase to avoid generation of pollutants. 22nd September, 2023 THE KENYA GAZETTE Impacts Proposed Mitigation Measures • Ensure performance of the de-dusting system is optimally sufficient to ensure no noxious odour and dioxins are emitted through the stack. • Employ gas treatment technology for dioxin reduction by ensuring that gas temperature in furnace is over 850°C, hot gas retention time in furnace is over 2 seconds, quick gas cooling to avoid dioxin regeneration and use of a catalyst to decompose dioxins or activated carbon injection or bed to absorb dioxins. • Use a semi-continuous charging type Electric Arc Furnace (EAF) as opposed to continuous charging type to ensure that the exhaust gas temperature from the furnace is relatively high and is stable to attain over 850°C gas temperature in furnace and over 2 seconds hot gas retention time in furnace. Dust pollution • Fully enclose the Electric Arc Furnace (EAF). • Install a large capacity bag house to capture all dust as part of the pollution control system. • Continually monitor floating dust loading of the workspace atmosphere and where necessary systematically change design and operation criteria based on the relationships between off-gas emission pattern, in-house gas stream, operational sequence of the de- dusting system, and floating dust loading of the workspace atmosphere. • Install an isolation wall for the yard, properly arrange ventilation air inlet positions and increase flow rate of air through the canopy hood to decrease dust loading. • Dust treatment by either solid reduction process or smelting reduction process to recover valuable metals from the dust and to make the residue chemically harmless for disposal. The solid reduction process partially reduces iron oxide to FeO, whereas, the smelting reduction process melts down and reduces almost all the metal oxides in the dust. Excessive water demand • Explore alternative sources of water that can be used such as roof catchment, rock catchment and collection from neighboring quarry pits to minimize drawing water from local pipeline for industrial use. • Provide adequate water storage tanks on site to store water from roof catchment from the extensive roofs of the go downs during rainy season that can be used in cooling of plant and equipment. • Minimise water demand by ensuring used water from the cooling circuit is routed through an adequately sized and effective cooling tower and pressure filter to filter the water for recycling purpose. Traffic congestion • Develop and implement a traffic marshal plan. • Provide sufficient parking/ holding area for traffic delivering raw materials and collecting finished from the steel mill Liquid waste generation • Provide appropriate containment structures /banding to collect any spills. • Provide for oil spill absorbents for quick absorption of any accidental spills. Noise and vibration • Develop and implement a comprehensive noise conservation programme that includes training, equipment maintenance, engineering controls, use of PPEs and noise level Impacts Proposed Mitigation Measures measurements. • Ensure the site is secured by appropriate noise attenuators. • Employ appropriate engineering controls to minimize noise production from plant and equipment.
