GAZETTE NOTICE NO. 15074

PURSUANT to regulation 21 of Environmental (Impact Assessment and Audit) Regulations, the National Environmental Management Authority (NEMA) has received an Environmental Impact Assessment Study Report for the implementation of the proposed preliminary and detailed engineering of missing link roads in Nairobi. The Proponent (Kenya Urban Roads Authority (KURA) of the proposed preliminary and detailed engineering of missing link roads in Nairobi. The proponent is proposing to carry on construction of five 26th October, 2012 THE KENYA GAZETTE new roads namely Accra Road Extension, Muratina Street, Ring Road Parklands (part), Ring Road Parklands Extension and Quarry Road Extension as well as dualling of Likoni Road Extension and Ring Road Parklands. The other component of the proposed project is provision of Non Motorized Transport (NMT) facilities along three major traffic corridors namely Rabai and Jogoo and Lusaka Roads. The following are the anticipated impacts and proposed mitigation measures: Possible Impact Mitigation measures Soil disturbance from road building and associated excavation. • Preference for dry season construction. • Avoid building roads in very steep terrain (>60% slope). • Spreading and/or compaction of disturbed soils incorporated into BOQ. • Install sufficient number of water bars and/or culverts along the roadside ditches to minimize the amount of water that accumulates; more if the area is steep. • On steeper slopes, line roadside ditches with riprap or sow grass or other cover crops to anchor the soil. • Add splash aprons or energy dissipaters at the outlet of culverts. • Add a requirement for the use of silt curtains or mulching for particularly important drainage areas. • Ensure adequate maintenance of such drainage ways to prevent blockages and failure. Water and soil contamination • Restrict movement of vehicles to one route only wherever possible. • Sprinkle water to allow particles to settle. • Encourage growth of vegetation cover. Road construction crossing water courses or wetlands. • Preference for dry season construction. • Identify suitable crossing points and re- align the road if needed. • Establish national riparian zone management policy and apply it. • Ensure adequate size & number of culverts/bridges passing watercourses or wetlands. • Avoid cut & fill road construction adjacent to torrential or flashy streams that could wash away the toe slope and sink the road platform. • Avoid constricting water flow with bridges or drifts. • Suitably sized bridges, both volume and spread to accommodate natural flows. Waste management • Designate a specific place as dumping site. • Where possible recycle the waste materials. • Encourage the worker to be responsible. • Enough and avoid deliberate dumping of waste materials such as plastic material. Noise Level • Limit Working hours in areas where there is settlement. • Use personal protective equipment in ears when working with equipment with high noise. • Regular maintenance of equipment and plants. • Impose speed limits. • Follow the stipulated noise level standards by NEMA and WHO. Water sources for construction work • Avoid abstraction of water from the rivers. • Avoid abstraction of water from rivers especially during dry season when the water volumes are low. • Water use should be obtained or supplied at night when demand is low. Increased vehicular traffic • Need for sealed roads within urbanized areas. • Speed bumps to slow traffic and enforcement of speed limits. • Construct wider shoulder widths or improved condition to allow for pedestrian use. • Road signage alerting drivers to the dangers of passing on a dusty road plus “no passing zones”. Construction and operation of borrow pits • In case the contractor opens up a borrow pit he will have to establish and implement a borrow pit management plan. • Engage local community authorities to take responsibility for long-term borrow pits in their area. Establishment, operation and decommissioning of construction crew camps • Proper siting with a preference for flat sites and standardized layout with adequate and clearly specified pollution safeguards. • Careful attention to water supply issues so as not to disadvantage local residents with whom these are shared during construction. • Full cleanup and decommissioning costs incorporated into BOQ. Dust impact • Frequent heavy watering is proposed to help reduce dust in site route and surrounding areas. Displacement of Businesses by Road • Identify an alternative space to relocate the affected traders. Storage and handling of materials • Ensure that safety procedures are followed, wearing of personal protective equipment, having fire prevention plan and fire equipment, training workers handling them and maintenance of construction vehicles. Impacts on Soil and hydrology • Incorporate erosion control measures • Works on culverts to be done in dry season. • Proper disposal of construction debris and solid wastes from impending water bodies and drainage systems. • Proper handling, storage and disposal of oil wastes. • Proper disposal of wastewater sewage at contractors’ workmen camps. • Maintain plant and equipment. • Maintenance of construction vehicles should be carried out in the contractors’ camps.
