GAZETTE NOTICE NO. 9009

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 Urban Roads Authority, is proposing to undertake the construction of Upper Hill–Mbagathi Link roads. This proposed project entails the construction 2km. long dual carriageway with intermittent service roads/slip roads of approximately 4km and rehabilitation of roads within Kenyatta National Hospital [KNH] and parking of approximately 5 km. The following are the anticipated impacts and proposed mitigation measures: Impacts Proposed mitigation measures Material sourcing • Aggregates and rock will be sourced locally from an established quarry in Nairobi City County instead of starting another quarry for purposes of the Proposed Road construction. • Purchase gravel and sub grade Soil- Murram from an established quarry in Nairobi City County instead of starting another quarry. • Carry out inspection of each of the site’s soil stability before excavation. • Cordon off the gravel site areas to keep livestock and children off. • The use of burrow pits for material spoil sites may be approved by the RE (and/or with the appropriate consent of the “landowner”). Where this occurs, the materials spoiled in the burrow pit shall be profiled to fit into the surrounding landscape and covered with topsoil. Clearing of vegetation • Ensure proper demarcation of the Project area to be affected by the construction works. This will be aimed at ensuring that any loss of vegetation is restricted to the actual Project area and avoid spillover effect on the neighboring areas. • Clearing of work sites and roadside vegetation will be done to an acceptable minimum. Building materials • Availability and sustainability of the extraction sites as they are non- renewable in the short term. • Landscape changes e.g. displacement of animals and vegetation, poor visual quality and opening of depressions on the surface. Noise pollution and vibration • Prescribe noise reduction measures if appropriate e.g. restricted working hours, transport hours and noise buffering. • Inform the surrounding community on the permissible noise levels and best working hours. • Use quiet equipment (i.e. equipment designed with noise control elements) and regular maintenance of machinery to ensure that noise produced from machinery is kept to a practicable minimum. • Construction shall be carried out in accordance with the standard procedures. All plants and construction equipment’s shall be fitted with noise control measures and shall strictly conform to the Environmental Management and Coordination Act (Noise and Excessive Vibration Pollution) (Control) Regulations, 2009 and the Occupational Safety and Health Act, 2007. Dust emission • All dusty materials shall be sprayed with water prior to any loading, unloading or transfer operation so as to maintain the dusty materials wet. • Cover stockpiles of sand, soil and similar materials or surround them with wind breaks. • Watering all roads used for any vehicular traffic at least twice per day of active operations or road used for any vehicular traffic once daily and restrict vehicle speed to 15 mph. • Personal protective equipment to be worn. • Post signs that limit vehicle speeds onto unpaved road and over disturbed soils. • Strict adherence to Air quality Regulations, 2014. Solid waste generated • Carefully budget to ensure that the amount of construction materials left on site after construction is kept minimal. • Consider the use of recycled or refurbished construction materials. • Purchase and use once-used or recovered construction materials. This will lead to financial savings and reduction of the amount of construction debris disposed off as waste. • Use of durable, long-lasting materials that will not need to be replaced as often, thereby reducing the amount of construction waste generated over time. • Use of construction materials that have minimal packaging to avoid the generation of excessive packaging waste. • Adherence to Waste Management Regulations, 2006. Increased water demand • Ensure that water is used efficiently at the site by sensitizing construction workers to avoid irresponsible water use. • An assessment and evaluation of the identified water sources should be done against the estimated water demand during construction. These details should be provided to the Water Resource Management Authority before a license for abstraction is issued. Storm water run-off • Put in place measures aimed at minimizing soil erosion and associated sediment release from the proposed Project sites during construction. These measures will include levelling the proposed Project sites to reduce run-off velocity and increase infiltration of rain water into the soil. 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 structures will be designed. • Adherence to Water Quality Regulations, 2006. Traffic impact • Heavy commercial vehicles delivering material shall observe designated speed limits for the area. • Proper signage and warnings shall be placed at appropriate places. Delays in transportation • Plan itineraries for site traffic on a daily basis throughout the project. • Erect temporary road signs that are visible both during the day and at night indicating road works and restrictions. • Set aside footpaths. Oil and fuel spills • Control dangers of oil and fuel spills during construction by maintaining machinery in specific areas designated for this purpose. • Prompt cleaning of oil and fuel spills, and proper disposal of clothing and rags contaminated with oil. Waste water • No grey water runoff or uncontrolled discharges from the site/working areas (including wash-down areas) to watercourses and/or water bodies shall be permitted. • Water containing such pollutants as cements, concrete, chemicals and fuels shall be discharged as the Waste Regulations, 2006. This particularly applies to water emanating from concrete swills. • Prevent runoff loaded with sediment and other suspended materials from the site/working areas from discharging to watercourses and/or water bodies. • Potential pollutants of any kind and in any form shall be kept, stored and used in such a manner that any escape can be contained and the water table not endangered. • Wash areas shall be placed and constructed in such a manner so as to 15th September, 2017 THE KENYA GAZETTE ensure that the surrounding areas (including groundwater) are not polluted. Occupational health and safety • Provide First Aid Kits on site • Proper signage and warning to public of heavy vehicle turning. • Ensuring Building Strength and stability. • Provide clean water and food to the workers. • The contractor to abide by all construction conditions especially clause B12 which stipulates health safety and workforce welfare. • Comply with the provisions of OSHA 2007.
