GAZETTE NOTICE NO. 10431

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, TAVEVO Water and Sewerage Company Limited, is proposing to develop a decentralized treatment facility comprising the operator store, receiving bay/balancing tank, anaerobic reactor, vertical flow constructed wetland, sludge drying bed and waste disposal unit with a capacity of 50M3/day (DTF-50) for the treatnment of sludge from Mwatate town (Pelekeza, Kariobangi, Kitivo and Soko ya Zamani areas) Taita Taveta County. The following are the anticipated impacts and proposed mitigation measures: Aspect Potential -VE impact Mitigation I. Air / Ambient • Emission of dust • Water rough road to environment during transport construction site of building periodically during materials and construction period. construction activities. • Re-vegetate the site as appropriate after construction. • Expedite construction so that it can take the shortest time possible. • Construction should be carried out only during daytime. 0800-1700hrs. • Provide workers with PPE if working in noisy section. • Hoard site to reduce noise from noisy equipment. • Machinery should be well maintained to reduce noise resulting from friction. • Limit unnecessary hooting. • Provide relevant signage at the construction site on construction activity and timings. The number of construction equipment operating simultaneously shall be minimized through efficient management practices. • Vehicle idling time shall be minimized. • Proper servicing of machinery as per the manufacture's specifications to reduce emissions. • Incinerator chimney stack will be at of minimum 4 metres height • The incinerator must always be maintained to ensure complete combustion, less pollution • Ensure efficiency and optimal operation of all units • Provide relevant PPE to DTF staff • Temporary dykes to prevent surface runoff • Use designated route to site. Possible Impacts Water sources Increased generation of waste Public health and occupational safety Aspect 2. Soil • Emission of • smoke from vehicles and equipment. • Emission of Smoke from incinerator • Odour from faecal sludge in DTF • Soil erosion during construction • Soil compaction from vehicles and machinery. 11th December, 2020 THE KENYA GAZETTE 4933 3. Water • Contamination of • water sources. • Control construction activities especially during rainy conditions. • Re-surface open areas after completion of the project and introduce appropriate vegetation. • Provide suitable storm water drainage channels to effectively discharge water to safe areas. Designate areas for parking vehicles and machinery. Ensure incinerator waste (ash) is disposed of in designated areas. Line disposal pit with right plastic gauge. Educate workers on water conservation and waste management. Temporary dykes to prevent surface runoff, especially if construction coincides with rainy season. Educate workers on water conservation and waste management. Only effluent with mandatory BOD/COD levels will be released to the environment. • Community education on proper use of water released from DTF. Only effluent with mandatory BOD/COD levels will be released to the environment. • Mosquito bio-control (e.g. fish like minnow, tadpoles- frogs, etc.) • Ensure proper demarcation and delineation of the project area to be affected by construction works. Designate access routes and parking within the site. Aspect Potential . VE impact Mitigation • Habitat alteration. • A.ppiopriate ndscaping after end of e....Aruction to maintain a green environment. • Provide waste bins strategically within the construction site. • Cover bins to prevent access by vermin, and minimise odour and dust. • Provide temporary sanitary facilities for construction workers. • Provide clean water for workers. • Conduct EHS education for site workers. • Provide workers with relevant PPE depending on task (ear muffs, gloves, mask, boots, helmets, overalls). • First-aid kit should be provided within the site plus at least 2 first aiders. • Food handlers preparing food the workers at the site should be controlled and monitored to ensure that food is hygienically prepared. • Appropriate PPE will be provided to DTF workers. • Dispose of in properly designated and properly lined pit. is available for inspection (a) Principal Secretary, Ministry of Environment and Forestry, NHIF Building, Community, P.O.

Biodiversity • Loss of flora and fauna. Preserve individual trees within the site that do not fall on the actual construction area. • The area will be restored to its original state after construction.
