GAZETTE NOTICE NO. 9195

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, Central Rift Valley Water Works Development Agency (CRVWWDA), intends to develop Kilgoris and Lolgorian Water Supply and Sanitation Project. The project is intended to deliver a supply of potable water to Kilgoris and Lolgorian in Narok County. The new water supply system has been proposed with the following components: • An intake at Mogor River with a throughput capacity of 1,800 m3/day. • A raw water pump system with three pumps (two duty and one standby) each with a capacity of 50 m3/hr against 40 m head. • A raw water rising main, steel pipeline (1000 m long) that shall deliver the raw water to a proposed water treatment plant with a throughput capacity of 1800m3/day. • Water treatment system comprising maze hydraulic mixing flocculation basin, chemical aided sedimentation basins, rapid sand filters and contact tank. • Clear water pump station: having three pumps (two to be duty and a standby, each with a discharge capacity of 45m3/hr and head of 190m) and 225kVA standby generator. • A rising main, 9500 m long cement lined steel pipe, that shall deliver clear water to an underground storage with a capacity of 500 m3. • HDPE gravity mains that shall transmit water to Kilgoris (7 km long) and Lolgorian (28km long) towns and their environs. Environmental and Social Impacts Mitigation Measures Construction Phase Soil erosion and disposal of excavated soil • Excavated soil will be used in the proposed project sites for development of impounding structures, re-spreading in areas to be landscaped to enhance aesthetics along the wayleave area and the development of access roads. 4468 4468 Environmental and Social Impacts Mitigation Measures • Works program should be in line with Kilgoris and Lolgorian weather pattern so as to avoid such works during rainy seasons. Soil and river water contamination • Plan emergency response measures in case of accidental spills of hydrocarbons, cement and any foreign materials. • Maintenance of construction equipment to be done on designated purpose-built surfaces. • Placing of sand bags along drainage channels and the river bank to prevent siltation of the river. • Any on site/camp storage areas for fuels, oils or other liquid chemicals would be sited away from surface water drains, and on impermeable base. Loss of productive land and assets • An Abbreviated RAP study shall be undertaken prior to commencement of the project in order to compensate the project affected persons. Loss of flora and habitat for avifauna • Construction zone limits should be identified and physically marked, to avoid or minimize unnecessary damage of existing vegetation • Where clearance of vegetation is unavoidable, incorporate landscaping with local tree species and plants approved by KFS. Noise and vibrations pollution • Noise levels at the construction site boundary should be kept within acceptable limits of 60 dB(A) during the day and 35 dB(A) during the night as stipulated in the EMCA (Noise and Excessive Vibration Pollution) (Control) Regulations, 2009. • Workers to use ear plugs for noisy operations. • Regular maintenance of equipment; and • Noisy operation to be scheduled outside school learning hours. Air pollution by dust and greenhouse gases • Stabilize unpaved access roads, parking areas and staging areas at construction sites by soil compacting, and regular sprinkling of water to reduce on dust. • Minimizing number of motorized vehicles in use and number of trips through a traffic management plan. • Construction vehicles should adhere to speed limits within construction roads to prevent raising dust. Spread of HIV / AIDS and STI related diseases • Awareness campaigns on HIV/AIDS and STIs. • Provision of condoms to the workforce; and • As much as possible, unskilled labour to be recruited from the project area. Solid and liquid/sewage waste disposal • Contractor to put in place well labelled solid waste segregation bins and ensure final disposal of the waste stream at designated dump sites • Provision of appropriate sanitation facilities for use by workers; and • Sale of waste such as cartons and cement bags to waste paper recyclers. Occupational and public health and safety • Contractor to implement requirements of Occupational Safety and Health Act 2007 including provision of personal protective equipment (PPE), and carrying out frequent toolbox talks and safety trainings for workers. Environmental and Social Impacts Mitigation Measures Employment opportunities • The contractor should as much as possible hire the local unskilled labour • At end of construction phase, the contractor should notify the employees in advance on the project closure date and adequately compensate them; and • Dismissal procedures to be compliant with Employment Act, 2007. Noise and air pollution from decommissioni ng of the contractor’s camp • Schedule noisy activities during the day time period. • Use silencers on machines where possible. • Maintenance of machinery so as to reduce noise. • Practice dust management techniques, including watering down during drier period. • Set up dust barriers/ screens at strategic locations. • Provide and enforce the appropriate use of PPE against dust. Operation Phase Contamination of the water source • Continuous monitoring of water treatment effluent to ensure adherence to the EMCA (Water Quality) Regulations, 2006 and EMCA (Waste Management) Regulations, 2006. • Notification of downstream community in case of unprecedented overflow of wastes from water treatment sludge lagoons. A communication protocol should be developed for this. Air pollution from operation of generators • Regular inspection and maintenance of installed generators according to manufacturer’s specifications. • Regular servicing of generators; and • Proper ventilation of generator room(s) to safeguard health and safety of operation and maintenance staff. Occupational safety and health risks (i.e. exposure to chemicals and electricity hazards) on staff that will be working at the water treatment plant • Provision of appropriate personal protective equipment (PPEs) for the operation and maintenance staff including safety glasses, hard hats, safety shoes, insulating (rubber) gloves with leather protectors, insulating sleeves, and flame-resistant clothing. • Scheduled staff training on handling of hazardous chemicals, tool box talks, and general health and safety training as per Occupational Safety and Health Act, 2007 The full report of the proposed project is available for inspection during working hours at: (a) Principal Secretary, Ministry of Environment and Forestry, NHIF Building, Community, P.O.
