GAZETTE NOTICE NO. 6784

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. Water • resources/increase- ed water demand • Public health, • occupational health and safety. The proponent, Sogea Satom Kenya proposes to set up a hardstone quarry and camp which is located in Sachangwan, Molo Subcounty, in Nakuru County. The quarry is intended to supply aggregate materials for the construction of the Rironi — Nakuru — Mau Summit highway (A8). Other installations at the site include: crusher plant, asphalt plant, emulsion plant, mixing plant, workshop, precast yard and other support infrastructure such as offices, sanitation facilities. The main processes during quarrying will include site clearance, blasting, excavation, material extraction, stockpiling, stone crushing, material testing and transportation. Infrastructure utilities include sinking one borehole, installing power on site and construction of a septic / soak pit for waste water management. The following are the anticipated impacts and proposed mitigation measures: Possible Impacts Mitigation Measures Air pollution • Training and sensitizing workers on dust suppression measures and impact on health • Implement dust suppression measures e.g., sprinkling water • Provide PPE for workers in dusty areas • Annually monitor air quality within the quarry site and its environs • Proper and frequent maintenance of construction vehicles to minimize exhaust fume emissions • Implement air quality monitoring plan Noise and excessive • Maximum charge weight for blasting plans vibrations should be 100 kilograms or alternative technology that generates noise and vibration that is compliant to Excessive Noise and Vibrations Regulations requirements. • Rock breaking methods adopted should be based on a balance between suitability, the required payload, cost and the impact on the environmental receptors. • Employ qualified personnel to handle explosives • Blasting should take place at pre-arranged designated times and the affected public, within approximately 1 km radius, duly informed. • The proponent should map out all susceptible structures within 300 m radius before commencement. • Inform potentially affected people or institutions located within 250 m of a potentially noisy activity at least one week in • Regular monitoring of noise and vibration Land degradation • Strict adherence to provisions of the and landscape Integrated Land Use Guidelines of 2011 scarring • Revegetation of the site to the native species identified during baseline studies Waste management • Prepare a site-specific waste management plan • Provision of properly labelled and strategically placed waste disposal containers at all the places of work • Where feasible recycle construction waste especially containers and cartons. • Involve local residents on the removal and disposal of the spoil and solid wastes to approved dumping areas. Possible Impacts Mitigation Measures • Use of a septic tank / soak pit to manage waste water • Water from concrete batching plant and asphalt plant should be directed to a conservancy tank for treatment and sedimentation prior to discharge Risk of accidents • Undertake a detailed risk assessment once and injuries to all the installations have been established workers • Prepare and implement an Occupational Health and Safety Management Plan • Engage a competent safety officer on site and train workers on safe work procedures and basics on health and safety at the work place. • Provide an insurance cover for all the workers and standard first aid kits • Erect warnings signs at all quarry entries and in areas with high cliffs • Provision of relevant PPE helmets, ear muffles, reflector jackets, safety boots among others as appropriate. Community health, • Fence off the entire quarry and delineate the safety and security quarry site from the rest of the project site • Strict adherence to blasting schedules and notification / warning systems • Engage a registered and licensed blaster to undertake the blasting works on site • Warnings signs of appropriate font size and in the appropriate language should be erected in all quarry entries and in areas with high cliffs Exposure to Soil • Areas susceptible to soil erosion should be erosion closely monitored for evidence of soil erosion and controlled • Stage site clearance to minimize exposure to soil erosion Soil pollution • Ensure proper maintenance of construction vehicles to minimize spills and leaks • Avail a spill kit on site to manage any accidental spills/leaks that may occur • Servicing of vehicles in a bunded area so that any spills are contained Vegetation loss • The clearance of the site for construction purposes shall be kept to a minimum. • The use of existing cleared or disturbed areas for construction of offices, workshop and sanitary facilities, stockpiling of materials etc. shall be encouraged; • Areas to be cleared should be agreed and demarcated before the start of clearing operations; Faunal habitat • Restrict vegetation clearance to the project disturbance footprint • Decisions to clear should be carefully evaluated prior to implementation • As far as practically possible the project site should be revegetated with species endemic to the project area Water pollution • Blasting should only be done by a person qualified and registered with Department of Mines and Geology 10th June, 2022 THE KENYA GAZETTE 3459 Possible Impacts Mitigation Measures • Ensure runoff from concrete batching plant areas are contained or directed into a sedimentation tank or pond for retention and treatment • To the extent possible the quarry area should be free draining to avoid ponding • Use of sandbags or silt fences to prevent sediments from leaving disturbed areas • Store soil heaps and aggregate stockpiles away from water ways and on flat surfaces to avoid washing sediments downstream • Servicing of vehicles in a bunded area so that any spills are contained Spread of • Conduct regular campaigns to create HIV/AIDS and stis awareness on HIV / AIDS and STIs prevention and control • Provision of condoms on site and locating them in strategic locations to improve access • Post HIV AIDS prevention posters at strategic locations within the site Spread of Covid 19 • Have in place COVID 19 prevention measures • Provide wash stations or sanitizers for workers around the site • Adhere to the recommended Ministry of Health measures by the government to control spread of the virus. Child labour • Recruitments should be done using identity cards to ensure that all employees are 18 years and above. • Provision of designated sheds for the vendors at the project site to vet all the vendors • Prohibit hawking in and around the project site Disruption of • The schools in the area should be informed learning one week prior to the blasting. • Blast on weekends or after school hours when there are few or no school activities taking place. • Periodic sprinkling of water in dusty areas to reduce the amount of dust produced at any given time.
