GAZETTE NOTICE NO. 8987

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 proponents, the Air Travel and Related Studies Limited is proposing to construct a Collage on Plot L.R. Nos. Ngong/Ngong 9528, 94875 and 94876, along Baboon Crescent Road. The proposed development will comprise of the administration block and students hostels block that will accommodate 1050 students and associated ancillary. The common land uses adjacent to the site are educational, town houses and public purpose (churches). Possible Impacts Proposed Mitigation Measures Vegetation disturbance • Minimize vegetation loss especially trees. • Ensure proper demarcation and delineation of the project area to be affected by construction works. • Introduction of vegetation (trees, shrubs and grass) on open spaces and around the project site and their maintenance. • Design and implement an appropriate landscaping programme to help in re- vegetation of part of the project area after construction. High demand of raw material • Ensure accurate budgeting and estimation of actual construction material required to minimize wastage. • Local suppliers can supply the building materials to the site. • Recycled, refurbished or salvaged materials can be used to reduce the use of new raw materials and divert the materials that would be dumped at the dumpsites. Increased storm water, runoff and soil erosion • A storm water management plan that minimizes impervious area infiltration by use of recharge areas and use of detention and/or retention with graduated outlet control structure will be designed. • Minimize vegetation clearing as much as possible. • Apply soil erosion control measures e.g., levelling project site to reduce run-off velocity and increase infiltration of storm water into the soil. • Construct rainwater harvesting and storage mechanism to reduce surface water runoff. Possible Impacts Proposed Mitigation Measures • Construction of water storage tanks to collect storm water for domestic uses. Solid waste generation • Reuse and recycle of material should be encouraged all the time especially from the demolished building. • Non-recyclable or reused wastes generated should be collected by licensed waste collectors/transporters to be taken for dumping at NEMA licensed dumping sites. • Provide facilities for proper handling and storage of construction materials to reduce the amount of waste caused by damage or exposure to the elements. • Through accurate estimation of the sizes and quantities of materials required, order materials in the sizes and quantities they will be needed, rather than cutting them to size, or having large quantities of residual materials. • Reuse packaging materials such as cartons, cement bags, empty metal and plastic containers to reduce waste at the site. • Waste collection bins to be provided at designated points on site. Sewage and effluent • Provide means for handling sewage generated by construction workers. Sewage to be deposited in onsite constructed a waste water treatment plant (WWTP), wastewater into soak pit and storm water into drainage Channel and waste water to be directed into soak pit. • Regular checks should be conducted on the waste handling facility for pipe blockages or damages to avoid release of the effluent into the environment. Noise pollutionand vibrations • Construction to be carried out between 8 a.m. and 5 p.m. • Provide appropriate PPEs like earmuffs to workers in high-noise level areas. • Suppressors or silencers on equipment and noise shields such as iron sheets around the structure should be used. • Construction vehicles and machinery engines are to be switch off if not being used. • Comply with maximum permissible noise levels for constructions sites as per Environmental Management and Co- ordination (Noise and Excessive Vibration Pollution) (Control) Regulations, 2009. • Apply for a License from NEMA whereby maximum permissible noise levels are to be exceeded. Dust emission • Provide workers with personal protective equipment like the dust masks. • Avoid excavation works in extremely dry weathers. • Water project site periodically during construction. • Provide dust screens or boundary wall along site boundary. Water demand • Construct rainwater harvesting and storage mechanisms (overhead water tanks). • Encourage wise use of water during construction and install water saving mechanism such as self-closing taps. 29th July, 2022 THE KENYA GAZETTE Possible Impacts Proposed Mitigation Measures • Promote recycling and reuse of water as much as possible. • Install a discharge meter at water outlets to determine and monitor total water usage. • Promptly detect and repair of water pipe and tank leaks. Energy consumption • Ensure electrical equipment, appliances and lights are switched off when not being used. • Ensure electrical equipment, appliances and lights are switched off when not being used. • Monitor energy use during construction and set targets for reduction of energy use. Fire outbreak • Provide fire hazard signs such as “NO SMOKING” and no open fires especially next to fuels, inflammable materials and electric wires. • Adopt an emergence response plans such as an assembly point, trained first aiders etc. • Ensure that all firefighting equipment are installed regularly, inspected and well maintained. Occupational health and safety risks • Erect warning signs warning of heavy machinery at construction site. Ensure that safety requirements as relates to factory and other places of work Act, 2005 and Occupational Health and safety Act, 2007. All workers should use appropriate personal protective equipment. All work at height should be done under strict supervision. All scaffolding, hoist and body harnesses should be inspected by approved government inspector. • Construct perimeter fence around the site. • Have fully stocked first aid kits and trained first aiders. • Ensure workers wear personal protective equipment on site at all the times. Occupational health and safety impacts • Sanitary facilities should be provided with respect to gender. Standard cleanliness of the facilities should be maintained. • Material safety data sheets to be made available for all chemicals/substances in the college. • Occupiers should always be sensitized on social issues such as drugs, alcohol, HIV/AIDS etc. General safety and security of the premises and surrounding areas • Ensure the general safety and security at all times by providing day and night security guards and adequate lighting within and around the premises. Environmental monitoring of the project • Undertake continuous environmental monitoring of the project for all the phases in liaison with the National Environment. • Management Authority and the proponent. This will ensure that environmental concerns are integrated into the project at every stage of implementation. Demolition waste • Use of an integrated solid waste management system i.e. through a hierarchy of options: 1. Source reduction 2. Possible Impacts Proposed Mitigation Measures Recycling 3. Composting and reuse 4. Combustion 5. Sanitary land filling. • All buildings, equipment, structures and partitions that will not be used for other purposes must be removed and recycled/reused as far as possible. • All foundations must be removed and recycled, reused or disposed of at a licensed disposal site. • Where recycling/reuse of the machinery, equipment, implements, structures, partitions and other demolition waste is not possible, the materials should be taken to a licensed waste disposal site. Rehabilitation of project site Vegetation disturbance; Land deformation: soil erosion, drainage problems • Implement an appropriate re-vegetation Programme to restore the site to its original status. • During the re-vegetation period, appropriate surface water run off controls should be implemented to prevent surface erosion. • Monitoring and inspection of the area for indications of erosion should be conducted and appropriate measures taken to correct any occurrences. • Fencing and signs restricting access should be posted to minimize disturbance to newly-vegetated areas. • Comprehensive Landscaping. Loss of income; Reduced ability to support dependants; Loss of quality of life; Loss of benefits i.e., medical, insurance cover etc. • Compensate and suitably recommend the workers to help in seeking opportunities elsewhere. • Assist with re-employment and job-seeking of the involved workforce. • Offer advice and counselling on issues such as financial matters. • The safety of the workers should surpass as a priority of all other objectives in the decommissioning project. • Adapt a project – completion policy: identifying key issues to be considered.
