GAZETTE NOTICE NO. 13771

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, Kenya National Highway Authority, proposes the development of the Muthaiga–Kiambu–Ndumberi Road (B32) into a dual carriage (B52/C558) that commences at Pangani and Muthaiga interchanges along Thika Road and proceeds through Kiambu Town ending at Ndumberi, Nairobi City and Kiambu counties. The following are the anticipated impacts and proposed mitigation measures: Possible Impacts Mitigation Measures OSHA related impacts • OSHA training and OSHA plan be implemented. • Contractor to have in-house OSHA committee. • Recording occurrences on site including all accidents. • Use of clear signages. • Training on first aid. • Provide sanitary facilities. • Awareness on HIV/AIDS and other related diseases. • Provide housing/camps with proper facilities. Effluent from works and camps • The contractor to have a proper waste disposal mechanism for the waste generated by construction workers. • Monitor effluent quality regularly to ensure that the stipulated discharge rules and standards are not violated. Solid waste • The contractor shall develop a waste management plan. • Stockpiling spoil soils for rehabilitation and landscaping purposes. • Using waste minimization techniques such as buying in bulk. • Allocating responsibilities of waste management and identifying all sources of wastes, and ensuring wastes are handled by personnel licensed to do so. 6892 6892 Possible Impacts Mitigation Measures • Making available suitable facilities for the collection, segregation and safe disposal of the wastes. • Creating adequate facilities for the storage of construction materials and chemicals and controlling access to these facilities. • Ensuring bins are protected from rain and animals. • The final disposal of the site waste shall be done by approved waste disposal agents. Air and noise pollution • To keep noise level within acceptable limits, construction activities shall where possible be confined to normal working hours. • Since the project area is densely populated with offices, hospitals, homes learning institutions and businesses, there will be need to notify the public as the project commences and in cases of interruptions. • Construction workers will be required to use PPE appropriately. • Equipment should e maintained regularly to reduce noise resulting from friction. • No unnecessary hooting by project vehicles across the major settlement areas. • Any complaints received by the contractor regarding noise to be recorded and communicated to KeNHA project engineer; as well as addressed immediately. • Sensitize workers on dust minimization techniques. • Construction works should be undertaken preferably during business hours. • Comply with all legal and statutory requirements as contained in EMCA air quality regulations that are cited elsewhere in this report. Blockage of wildlife and domestic animals movement • Include design features (e.g. wildlife overpass and some sections of the roads to be raised on pillars) to allow free movement between the two sides of the road around Gitooro showground to end of the proposed project for wildlife and various sections between Ngo’nyi and Gitimbine for domestic animals since the area is agricultural. • Contractor and workers be sensitized to the provisions in the new Wildlife Conservation Management Act, 2012. • Have a code of conduct amongst workers expressly banning any hunting of wild game for food or trophy. • Install speed calming measures when working within wildlife areas. • Install proper signage along the route to inform the construction drivers on the presence of wild animals. • Advocate for reduction of speeds along wildlife areas during construction. Traffic movements • A traffic management plan should be in place. • Clearly marked diversions. • Clearly marked signage. • The contractor will be required to plan Possible Impacts Mitigation Measures itineraries for site traffic on a daily basis. • Traffic management and control is mandatory throughout the project. Traffic impacts • Construction traffic entering or leaving the site will be scheduled for off peak hours to minimize additional congestion at road intersections and or disruptions in the regular traffic flow. • Erection of signs along access road to the project site warning motorists of the heavy/construction vehicles entering the access road shall be done. • Posting of speed limit signs along the access road to the project site to govern speed of transportation vehicles shall be done. A speed limit of 20kms per hour will be adopted. • Appropriate traffic warning signs, informing road users of a construction site entrance ahead and instructing motorists to reduce speed shall be posted along the main access to the project site for the entire construction period. • All transport vehicles to comply with weight limits as prescribed by the Kenya National Highways Authority (KeNHA). The KeNHA has a standard for loads per axel that all trucks exert on roads and this shall be complied with. • Water will be regularly sprinkled along the haul roads to suppress dust. • Utmost care will be taken to prevent spillage of stones and spoils from the trucks during transportation. Vegetation clearing • Except where inevitable no vegetation should be cleared. • Where vegetation is cleared, the contractor should replant the vegetation after the project. • The clearance of the site for construction purposes shall be kept to a minimum. • The use of existing un-vegetated or disturbed areas for the Contractor’s Camp. • Areas to be cleared, especially borrow pits and campsites must be cleared to in such a way that damage to adjacent areas is prevented. • Although all vegetation encroaching into the road reserve must be cleared to give room for visibility, this should be restricted to the RoW. • Trees should be trimmed rather than removed wherever possible. • To plant indigenous and native trees along the project road in all the above mentioned sites. • The use of fuel wood by construction workers should be discouraged, workers to be encouraged to use clean energy sources. • Ensure suppliers are legally complaint and environmentally sensitive. Fuel, oils hazardous substances and other waste • Hazardous material shall be stored properly and clearly labelled. • Areas for the storage of fuel and other flammable materials shall comply with 17th December, 2021 THE KENYA GAZETTE Possible Impacts Mitigation Measures standard fire safety regulations. • Chemicals and fuel shall be stored in storage tanks within a secure compound. • Pipe-work carrying product from the tank to facilities outside the containment shall be provided with secondary containment. • Tank equipment such as dispensing hoses, valves, meters, pumps and gauges shall be located within the containment or provided with own containment. • Fence of the tank compound with locks or other adequate security controls at the site. • Any chemical or fuel spills shall be cleaned up immediately. • The spilt liquid and clean-up material shall be removed, treated and transported to an appropriate site licensed for its disposal. Social impacts • Ensuring equal opportunities in provision of employment. • Promotion of social cohesion and integration. • Awareness of STI and HIV/AIDS. • Corporate social responsibility and supporting communities. • Proper compensation of PAPs. • Creating awareness towards the diversity of cultures and different economic background of the people staff and residents through sensitization. • Allowing the residents and businesses to form social groups and networks that build social capital. • Targeting social investment programs towards the local communities and region. Physiography and geology • Soil erosion measure should be put in place. • Maintenance of the slope’s gradient. • Ensure that the site is reclaimed/rehabilitated in the decommissioning phase of the project. Soils • All earth cuttings need to be at a gentle angle, wherever possible and economic, in order to allow vegetation to grow. Steep side-slopes tend to result in seeds washing away rather than having a chance to become established. • Waste oil to be collected by a NEMA licensed waste dealer. • Excavations to avoid accelerating situations of soil erosion. • Solid waste to be handled well by a licensed NEMA waste handler or better still the contractor should work together with the county to ensure that the waste is disposed- off appropriately and to the appropriate place.
