GAZETTE NOTICE NO. 9346

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, Green City Incinerators Limited, is proposing the installation of an incinerator that will contribute to safe and proper treatment of hazardous waste from Machakos County and the surrounding counties. The following are the anticipated impacts and proposed mitigation measures: CONCERNS DURING SITE CONSTRUCTION AND INSTALLATION PHASE AND PROPOSED MITIGATION MEASURES Impacts Mitigation Measures Dust disturbances • Employees involved in the construction and installation work to be provided with dust masks. • Green City Incinerators Limited and contractor to enforce strict use of personal protective clothing. • Complains of dust related aliments among employees given access to medical attention. • Sprinkle water on site. Solid waste • Solid waste and other excavated materials to managed according to the Waste Management Regulations of 2006. • Waste handling bins to be provided for workers onsite, each bin should have a lid which should always be covered. • Colour code to be used to distinguish waste bins of different waste. • In a case of cement bagging be stored recycled or put into different usage. Occupational injuries • Appropriate personal protective equipment such as safety belts for workers working at height to be provided. • Proper use of PPE provided. • Appropriate training of workers of ways of working safely. • Appropriate supervision at workplace. • Rest times to be strictly observed to reduce stress. POTENTIAL CONCERNS DURING OPERATIONAL PHASE AND PROPOSED MITIGATION MEASURES Air pollution • Screening incoming wastes at the (emission of toxic incinerator to reduce incineration of wastes pollutants, flue (such as batteries) that are non- gases, particulate combustible and are likely to produce air matter and pollutants when burned. • Only NEMA licensed vehicles to be used to collect and hazardous transport waste to the facility. • Collection trips or take such other measures needed to eliminate or minimise the mixing of incinerable and non- incinerable wastes. • The ash be contained at all times both inside and outside the facility. • Use of water to quench the ash, simultaneously reducing dust generation and minimizing the possibility of ash-dust inhalation or ingestion by workers. • Enclosed ash-handling systems throughout the incinerator. • Fly ash residues to be disposed off only after it has been solidified in the incineration plant. • Ash be handled and disposed in a secure hazardous-waste landfill that is designed to ensure that there will be no groundwater pollution. • Regular testing of ash to determine its toxicity. • GHC Emissions be reduced by modifying operating characteristics reagent type, and injection rate, and by selecting optimal combustor designs and emission-control technologies. • Use and continued calibration and maintenance of continuous monitors of emissions and process characteristics provide real-time feedback and facilitate maintenance of optimal operating conditions at all times by incineration operators. • Computerized continuous emission monitors (CEMs) for CO, 02, Sox, Nox, and HCI. • Quarterly stack emission assessment of the incinerator. • Certification procedure for incinerator control-room operators. • Wet-scrubber wastewater be discharged to on-site wastewater-treatment system in conjunction with EPZA. • Plant operators and worker training in hazardous-material management and annual refresher courses. • Employees should be provided with protective gear (Safety boots, overalls, helmets, goggles, earmuffs, respirators/masks and gloves. • A fully equipped first aid kit should be provided within the site and be managed by qualified person. • Provision of workmen's compensation cover (WIBA). • Safe operation procedures/ clear instruction provided to the workers and general public to ensure that safety is maintained. • Workers operating within the high temperature zones should not exceed 2hrs continuous presence or/as may be directed by the Occupational Health and Safety Experts. • Mounting of safety signage's within and outside the incinerator plant. Site flooding from • Rainwater from the constructed roofs storm water within the within the site to be harvested generation and collected and stored in underground collected tanks for later use. • Appropriate site landscaping to be employed. • Planting of trees on all open area to reduce surface run off. Increased vehicular • Company vehicles using Athi-River- traffic Kinanie road to always observe traffic rules guaranteeing residents, pedestrians, cyclist and other road users their space and safety while using the Road. • Speed limits to be strictly observed. • Motorist to be sensitised to use unleaded fuel as opposed to leaded fuel. Social issues conflict • Continuous public participation and engagement for improving the environmental impact assessment and increasing total welfare of different interest groups in Kinanie location and beyond as far as the incinerator operation is concerned. • Pursuing economic achievements with regard to social, public health and environmental issues that of concern to the locals through CSR. POTENTIAL CONCERNS DURING DECOMMISIONING AN] PROPOSED MITIGATION MEASURES Impacts Mitigation Measures Occupational injuries • Appropriate personal protective equipment provided and proper use. • Appropriate training of dismantling team and operators workers of ways of working safely. • Rest times to be strictly observed to reduce stress. Solid waste • Un-recyclable material to be transported by licensed waste transporters and disposed on NEMA approved landfill sites. • Ensure safety precautions have been observed at decommissioning especially in regard to sharp debris, heavy metals, etc. • Careful removal of lined ash pit on site • Use of NEMA approved waste handlers Site restoration an • Notify NEMA and other relevant rehabilitation authorities on intension to decommission operations at least 6 months in advance. • Carry out a decommissioning report and submit report to NEMA for review six months in advance, • Re-vegetate the project site with as much indigenous trees as possible • Monitor the site for one year.
