GAZE1TE NOTICE No. 13573 THE ENVIRONMENTAL MANAGEMENT AND CO-ORDINATION ACT (No. 8 of 1999) NATIONAL ENVIRONMENT MANAGEMENT AUTHORITY ENVIRONMENTAL IMPACT ASSESSMENT STUDY REPORT FOR THE PROPOSED KITALE TOWN SEWERAGE SYSTEM INVITATION OF PUBLIC COMMENTS 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, proposes to rehabilitate and expand the Kitale Sewerage System (Phase 1) involving rehabilitation of the existing 43km sewer network, construction of 45km trunk sewers and 53km secondary sewers, new plot connections including reconnection for realigned sewers, decommissioning of Bidii and Machinjoni WWTPs and Matisi maturation pond, construction of WWTPs at Sirende and Rafiki sites and associated works. The following are the anticipated impacts and proposed mitigation measures: Possible Impacts Mitigation Measures Impacts on water • Discharge of grey water or uncontrolled resource discharges from the site/working areas' (including wash down areas) to adjacent rivers shall not he permitted. • Water containing pollutant., such as cements, concrete, lime, ,,71-teinicals and fuels shall be discharged into a conservancy tank for planned removal from site. • Works that are likely to !enerate laden runoff such excavatiolE, will be undertaken preferentially during the drier months of the year; Dccember March. • The drainage system will be developed to prevent silt-laden runoff from entering surface water drains and streams. • Where possible an Sin buffer strip of existing vegetation will be maintained along the affected rivers such as River Koitobos and River Katalele. • Sheet and rill erosion of soil shall be prevented where necessary through the use of sandbags, diversion berms, culverts, or other physical means. • Topsoil shall be stockpiled to a 2m height separately from subsoil and shall be located away from drainage lines protected from rain, wind erosion and contamination. • Topsoil shall be evenly spread across the cleared areas when reinstated. • Accelerated erosion from storm events during construction shall be minimised through managing storm water runoff (e.g. velocity control measures). • Soil backfilled into excavations shall be replaced in the order to preserve the soil profile. • Mulch generated from indigenous cleared vegetation shall be spread across exposed soils after construction. • Strict adherence to EMP. Impacts on vegetation • Compensatory planting of trees i.e. cover plants at least twice the number of trees, within the project area. • Clearing of vegetation will be carried out during construction of works if deemed necessary. • Staged vegetation clearance is also recommended so as not to clear the entire corridor all at once. • The use of existing cleared or disturbed areas for the Contractor's Camp. stockpiling of materials etc. shall be encouraged. • Whenever possible, ail damaged areas shall be reinstated and rehabilitated upon completion of the contract to as near pie- construction conditions as possible. • Reinstatement of temporary construction sites and pioneer camps (if needed) should be done as swiftly as possible and always with suitable native grasses and other plants. Impacts on air quality • Developing a Dust Management Plan (DMP). • Recording all dust and air quality complaints, identifying cause(s), taking appropriate measures. Impacts on soil resource • Earth stockpiles will be seeded and, covered with geotextile mats or surrounded by a hund to minimise the risk of sediment-rich runoff. • Discharge into watercourses and water bodies will only be carried out under consent of the relevant governing bodies such as WRA. • Vegetation clearing and topsoil disturbance will be minimised where possible. • Liaising with local communities to forewarn of potentially dusty activities. • Close monitoring of dusty activities, noting that this may be daily visual inspections, or passive/active monitoring as parameter. • Planning potentially dusty activities so that these are located as far from receptors as feasible. • Erecting solid screens if feasible around stockpiles and concrete hatching. • Contouring temporary and permanent access roads / laydown areas to minimise • Removing dusty materials from construction sites as soon as possible if not being re-used. re-used materials should be covered or vegetated if 10th December, 2021 THE KENYA GAZETTE 6803 Possible Impacts Possible Impacts Noise and vibrations • impacts Community health • safety and security impacts Worker health and • safety and workers management impacts Pollution of water' resources by raw sewage from blocked sewer pipes • and manholes. Mitigation Measures possible. • Imposing speed limits on haul routes and in construction compounds to reduce dust generation. • Minimizing drop heights when loading stockpiles or transferring materials, • Watering shall be done to attenuate dust near sensitive receptors. The duration and frequency shall be set out in the Dust Management Nan and will consider water availability and any stakeholder grievances. • Revegetation of exposed areas if feasible. Siting noisy plant and equipment as far away as possible from human settlement, and use of barriers (e.g. site huts, acoustic sheds or partitions) to reduce the level of construction noise wherever practicable. • Works expected to generate significant noise will be executed during the day. • Alternatives to diesel and petrol engines and pneumatic units, such as hydraulic or electric-controlled units, will be used, where practical. • For machines with fitted enclosures, doors and door seals will be checked to ensure they are in good working order and that the doors close properly against the seals. • Throttle settings of plant and equipment will be minimized or turned off when not in use. • Equipment will be regularly inspected and maintained to ensure it is in good working condition. Additionally, mufflers, fittings and silencers will be routinely checked. Contractor will develop and monitor the implementation of a Community Health and Safety Management Nan (CHSMP). • Contractor will develop Emergency Response Plans (ERPs) in cooperation with local emergency authorities and hospitals. • Contractor will extend the Worker Code of Conduct to include guidelines on worker —community interactions and will provide training on the worker code of conduct to all employees including contractors and subcontractors and truck drivers as part of the induction process. • Contractor will provide primary health care and first aid at construction camp sites to avoid pressure on local healthcare infrastructures. Contractor will develop a Human Resources Policy, which will outline worker rights to be included in all contracts. • Contractor will prohibit the use of alcohol or drugs, which could adversely affect the ability the employee to perform the work safely or adversely affect the health and safety of other employees, community members or the Mitigation Measures environment. • Contractor and self-employed contractors will assess the Health and Safety risks related with the tasks to be performed during the construction phase. • Pre-employment medical assessments will be put in place as a workforce risk management tool to screen individuals for risk factors that may limit their ability to perform a job safely and effectively. • Contractor will ensure that training on health and safety measures is provided to all construction workers prior to starting to work. • Provision of PPE's to workers. • Contractor will implement regular health and safety checks and audits of workers, contractors and subcontractors and implementing sanctions in case of breaches of national standards and the Project's specific standards. • Contractor will establish a procedure for the recording and analysis of incidents. • Contractor will ensure that facilities and work sites are designed and maintained such that robust barriers are in place to prevent accidents. • Contractor will ensure that adequate clean water, adequate food and access to medical care is provided to all workers on the worksite and at accommodation. NZOWASCO will ensure proper and periodic maintenance of sewers and wastewater treatment plants. NZOWASCO will activate a community watch group for information sharing on the status of the sewers. • Regular cleaning of grit chambers and sewers to remove grease, grit, and other debris that may lead to sewer backups. • Design manhole covers to withstand anticipated loads and ensure that the covers can be readily replace-Ai if broken to minimize entry of garbage and silt into the sewer system. • Ensure sufficient hydraulic capacity to accommodate peak flows and adequate slope in gravity mains to prevent build- up of solids and hydrogen sulphide generation. Regular inspection of the system to ensure performance is maintained at high levels. Blockages should be detected and promptly replaced. NZOWASCO will ensure that the pond series have adequate water flow and aeration to reduce the potential of odour formation. The perimeter of the proposed site should be vegetated with trees and plants of varying heights thereby forming windbreaker and reduce dispersion of odour.

The proponent, Rift Valley Water Works Development Agency, proposes to rehabilitate and expand the sewerage system within Kakamega Town for the following lines; Kakamega Town Main Market-Kenya Farmers Association, Amalemba sewer, Referral Hospital sewer and the Milimani - Masinde Muliro University of Science and Technology (MMUST) sewer interconnections in the last mile connectivity works in Kakamega County. The following are the anticipated impacts and proposed mitigation measures: Mitigation Measures • Drivers should be instructed on the benefits of driving practices that reduce both the risk of accidents and fuel consumption, including measured acceleration and driving within safe speed limits. • Ensure that all vehicles involved in the transport of construction material and staff, and machinery involved in the construction is properly maintained and serviced. Machines must not be left idling for unnecessary periods of time; this will save fuel and reduce emissions. Use of dust control methods, such as corers water suppression. Ensure that all trucks carrying aggregate and sand are covered during delivery to the site. Ensure that all material (sand and aggregate) stockpiled on the site to be used in construction activities are regularly sprayed to reduce the effects of wind whipping. • Care must be taken in the unloading construction materials (aggregate, sand and cement) to prevent spillage. If a spill occurs, this should be cleaned up as soon as possible thereafter. • Retain a buffer area of trees and other vegetation generally around the perimeter of the development site which will serve as a natural windbreaks which may reduce the level of dispersion of dust particles generated during this phases of the development. • All raw materials must be sourced as close as possible to the construction site thus reducing the emissions from vehicular traffic. • All waste must be transported off-site for processing, not burnt or stored for any longer than is absolutely necessary. • If diesel and motor oil are to be stored on site, ensure that they are properly contained in a bounded area (With capacity to contain 11/2 times the amount of substances stored). This area must have signs indicating the storage of these substances erected. • Provide workers at the development site with chemical toilets during this phase of the development. A reasonable ratio would be fifteen (15) workers per toilet. • Store all raw materials away from the vicinity of water bodies located on the property to avoid contamination in these Possible Impacts Air pollution Water pollution Possible Impacts Mitigation Measures odour emanating from wet sludge. Risks associated with • NZOWASCO will dry sludge on the sludge from the drying beds before disposing it off. WWTP • Dried sludge could be used to make briquettes as a charcoal substitute or be sold to farmers as fertilizers. • Excess sludge can be disposed in a designated landfill which shall only be for disposing dry odorless sludge. Solid wastes impacts • NZOWASCO will develop a at WWTP screens comprehensive Waste Management Plan (WMP) for management of solid wastes from screen chambers. • NZOWASCO will employ personnel who will be in charge of maintaining hygiene and cleanliness of the WWTP including removal of solid wastes from screen chambers. • Properly labelled and strategically placed waste disposal containers shall be provided at all places within the WWTP. • Solid wastes once removed from screens shall be collected and disposed appropriately as required by waste Management Regulations of (2006) and Trans Nzoia County Government by laws. • Secure barriers to keep off the animals from interfering with the plant operations and safety will be put in place. • In the event of larger wildlife e.g. hippos, NZOWASCO will ensure appropriate consultations with the Kenya Wildlife Services (KWS) on appropriate management actions.
