GAZETTE NOTICE NO. 5415

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 Highways Authority is proposing to construct the Kiambu–Ngewa–Kibichoi (B30) Road which is approximately 22km long and the scope of work extends beyond covering the entire B30 Road. The road project is approximately 62 kilometres and commences on a Junction B32/B30 (Kiambu Road, opposite Kiambu Institute of Science and Technology) and proceeds through Kirigiti, Riabai, Ngewa, Kibichoi, Nembu, Ichaweri, Gatundu, Kang’oo, Mang’u and ends at Junction B30/A2 Thika Super Highway in Kiambu County. The following are the anticipated impacts and proposed mitigation measures: Project Activities/Impact Sources Potential Impact Proposed Mitigation Measures • Site clearance, • Removal of top soil, vegetation. • Road diversions • water abstraction • Construction of support infrastructures • Soil erosion • Depletion of vegetation cover • Air pollution, dust and noise • Loss of socially /economically useful vegetation/ land components • Install erosion control measures on exposed areas. • Control /manage excavation activities, earthworks. • Install drainage structures properly. • Landscaping, re – vegetation, backfill of exposed surfaces around the sites. • Planting of grass to be done within preparation and clearing phase and just before rains. Hydrology and drainage. • Soil erosion • Accidents • Water pollution • Roads design and related activities not to encroach on environmentally sensitive areas such as wetlands Replant road reserve with grass or stabilizing shrubs (e.g. vetiver grass) to prevent soil erosion. • Design adequate culverts for all crossings to accommodate peak runoff from effective catchments and swamps. • Setting up of site camp, offices • Disposal of solid waste at camp • Waste construction materials • Provide proper solid waste disposal facilities at camp. • Provide proper sanitation facilities. Excavation, acquisition work, transportation and storage of raw materials (gravel sites, hardstone, • Soil erosion. • Air pollution • Noise, aerial emission of dust • Land • Contractor to consult community and relevant authority before any work starts. • Identified quarry sites and borrow pit sites to be exhausted, reinstated and Project Activities/Impact Sources Potential Impact Proposed Mitigation Measures stockpile area etc) degradation • Loss of land value at raw material sites and stockpile • Loss of vegetation rehabilitated before opening other sections. • Limit earth movements to dry season. • Borrow pits should be rehabilitated. • Balance cut and fills to avoid deposition. • Use appropriate methods of controlling soil erosion. • Control speed of construction vehicles and impose speed limits for all. • Prohibit idling of vehicles. • Sensitize workforce. • Maintain work equipment River regulation, water acquisition impounding, abstraction and use. • Water pollution • Soil erosion • Social conflicts with communities • Solid waste, fuels, oil should not be discharged on the land surface and then into the river. • Cleaning and maintenance of equipment and machines to be done only at designated places. • Decommissioni ng and rehabilitation of raw material sites- quarry and borrow pits. • Landscaping of material stockpile and spoil areas. • Development of badlands • Land degradation • Abandoned borrow pits • Loss of land value around material sites (stockpile and spoil areas) • Loss of vegetation • Accidents at borrow pits, quarry sites • Institute Standard Operation procedures (SOP) • All materials from stockpile areas to be removed and the area to be landscaped. • All waste and surplus materials at spoil areas to be collected and disposed at designated places and not dumped within the road reserve. • Replant vegetation on reserve, diversion route upon completion. • Quarry pits to be covered with soil and thus creating farming land. • Borrow pits to be fenced and used as water harvesting points where applicable Harvested water to benefit communities nearby (alternative). • Plant trees at appropriate places to serve as pollution screen. Waste management • Generated waste resulting from various operations. • Oil pollution • Provide appropriate options for waste management. • Assess opportunities for reducing solid waste generation in particular of hazardous and undesirable materials (oils and grease). • Dumping of oil residuals and any other waste to be done in designated areas only. • Encourage segregation of waste from the source and use the 3R waste management approach: Reduce, Reuse and Recycle. 30th July, 2020 THE KENYA GAZETTE Project Activities/Impact Sources Potential Impact Proposed Mitigation Measures • Design provisional waste material storage for the sorted out waste at the site (e.g. spoil area). • Dispose all unwanted structures, wastes and unused materials in accordance to NEMA Waste Management Regulations. • Undertake an inventory of the type of waste and quantities.
