GAZETTE NOTICE NO. 5838

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,:, Tana Water Services Board, is proposing the construction of new sewage conveyance facilities and a Waste Water Treatment Plant (WWTP). The proposed works include construction of a sewer network of approximately '56.2 km of trunk sewers and manholes, inlet channel with screens, grit channel' and parshall flume, waste stabilization ponds, overflow chamber, sludge drying beds, office block with., a laboratory, two double grade 9 staff houses equipped with toilets, wash-up and changing facilities, perimeter fence, access roads and parking among other associated facilities and amenities in Mein County. The following.soe the anticipated impacts and proposed mitigation measures: Impacts Proposed Mitigation Measures Air quality • Service and maintain machinery according to manufacturer's instructions. • Spray water on access roads, stockpiles and cleared areas to minimize dust pollution. • Cover all vehicles ferrying construction materials Such as sand or aggregate to avoid dispersal of particles/dust along the roads. • Provide personal protective equipment gear such as dusk masks to workers. Impacts Proposed Mitigation Measures • Impose vehicle speed limits to 10 km/h in all areas within the site boundaries. Soil erosion and • Vegetation should only be removed from Contamination clearly marked areas. • Excavated materials and stockpiled soils should be covered or kept at appropriate sites. • Undertake appropriate soil erosion control measures along the trenches and WWTP sites. • Construction vehicles and machines must be maintained properly. to ensure that oil spillages are kept at a minimum. • Spill trays must be provided if refueling of construction Vehicles are done on site. • Materials, fuels and chemicals must be stored in s specific nnd secured area to prevent pollution . from spillages and leakages. The basic EMCA Regulations on of hazardous waste. management must be applied fully. • Train drivers and workers on oil and fuel management. Noise and excessive • Schedule road traffic movements to normal vibrations Working hours (0800Hrs — 1700Hrs). • Noisy equipment and vehicles on the site should be equipped with noise suppressing measures and ..kept in proper ' working conditions. - • Provide personal protection equipment such as ear muffs to workers operating in noisy areas.. • Pumps and generators should be stationed far away from areas that are sensitive to noise such hospitals. • Avoid unnecessary hooting and revving of engines. • Solid Waste • Develop a Waste Management Plan in compliance with Solid Waste Regulations 2006. • Recycle or re-use solid wastes where applicable in line with sound environmental management practices. • Dispose of non-recycled wastes to sites designated by Meru Municipal Council as dumpsites. • Organic wastes from construction camps can be composted. • Solid wastes from sewage inflow and site offices should be collected and dumped at designated dumpsites. • Sludge if not suitable for agriculture should be dispoied of by land filling. Waste water • Regular monitoring and inspection of sewer management lines to identify broken pipes and damaged manholes for repairer maintenance. • Use of high-quality' materials that• can withstand anticipated sewage loads and as recommended by the design engineers to prevent leakages and overflows. Clear and unclog blocked sewer lines within the shortest time possible to contain sewage spills and overflows. • Clean and disinfect contaminated site. Surface and ground • Construct oil-water interceptors or sumps. water • Provide pit latrines/portable toilets at the contamination camp and construction, sites for use by workers. Impacts Proposed Mitigation Measures • Store all raw materials away from the vicinity of water bodies along the project sites to avoid contamination. • Sensitize workers on proper waste disposal. Damage to existing • Obtain maps of existing underground underground infrastructure from relevant institutions to infrastructures avoid damaging them. • Locate, mark and exercise caution when excavating trenches to minimize chances of damaging such infrastructure. • Notify responsible institutions of any damage to ensure that services are restored within the shortest time possible. Occupational health • Conform to all the requirements of the and safety Occupational Health and Safety Act, 2007. • Provide ample warning signs and protection around open excavations, stacks of material, etc. • Train workers on the use of firefighting equipment and first aid. • Ensure that persons handling equipment and materials are suitably trained, and supervised. • Ensure that emergency contact numbers of the police, fire brigade and ambulance are available at the construction sites. • Provide sanitary facilities it construction sites and potable drinking water. • Report and record health, safety and environmental incidences as required by law.
