GAZETTE NOTICE NO. 3555

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 15th May, 2020 THE KENYA GAZETTE 1923 an Environmental Impact Assessment Study Report for the above proposed project. The proponent, Athi Water Works Development Agency is proposing to undertake the construction of Makutano Sewerage Project. The project will comprise; rehabilitation of the Ablution block in Kangari Market, laying of around 12.5km trunk sewer pipeline to serve Kimorori, Wempa, Kabati and Gitura, construction of a new sewerage treatment plant of capacity 3,000m3/d in Kihiu Mwiri area, Nanga Location, Mitumbiri division, Gatanga sub-county; laying of 15.5km of reticulation sewers and provision of 1000 household sewer connections in Murang'a County. The following are the anticipated impacts and proposed mitigation measures: Potential Impacts Proposed Mitigation Measures Noise and • Machinery, vehicles and instruments that vibration emit high levels of noise should be used on a phased basis to reduce the overall impact. • Where possible silenced machinery and instruments should be employed to reduce the impact of noise on the existing residents and workers. • Construction hours should be limited to the hours of 8.00 am. and 6.00 p.m. daily. • Provision of appropriate personnel protective equipment to the workers. Vegetation • Only clear vegetation that is absolutely clearing, soil necessary for the construction activities. erosion and sedimentation • Retain all mature trees (> 25 cm diameter at breast height during this phase of the development if possible. • Avoid the use of Invasive Alien Species in the landscaping activities • Cement mixing should be done in a designated area away from storm water drains. • Spilled cement or concrete should be collected and disposed away from natural water ways or storm water drainage. • Re-vegetation of exposed areas around the site should be carried out rapidly in order to mitigate against erosion. Solid waste • A site waste management plan should be generation prepared by the contractor prior to commencement of construction works. This should include designation of appropriate waste storage areas, collection and removal schedule and identification of approved disposal site. • Proper solid waste receptacles and storage containers should be provided, particularly for the disposal of lunch and drink boxes so as to prevent littering of the site. Air emissions and • Ensure that all vehicles involved in the ambient air transport of construction material and staff, quality and machinery involved in the construction is properly maintained and serviced. • Drivers should be sensitized on driving practices that reduce both the risk of accidents and fuel consumption including driving within safe speed limits. • Machines must not be left idling for unnecessary periods of time; this will save fuel and reduce emissions. Occupational • Ensure compliance with the Occupational health and safety Health and Safety Act, 2007. Proposed Mitigation Measures • There should be safety policy clearly displayed on the site. • Establish a Health and Safety Plan (HASP) for civil works areas and that the working hours are controlled. • Provide workers with appropriate Personal Protective Equipment (PPE). • Label all inflammable materials and store them appropriately. • Provision of adequate firefighting equipment capable of fighting all classes of fire. • Put — "No Smoking" signs in areas where inflammables are stored. • Undertake a Resettlement Action Plan which will act as guide for the compensation activities. • Develop HIV/AIDS awareness programs or initiatives to target the construction workers, community, institutions and the general members of the community, particularly the youth; with the objective of reducing the risks of exposure and the spread of HIV/AIDS within the project area. • Maximize hiring skilled and unskilled workers from the host community • Provide diversion routes where possible. • Give a construction itinerary in advance so that the potentially affected population can use alternative routes and start early to get to their destinations on time. • Erect warning signs of on-going works. • Formal request for permission to cross, break in and build the sewer lines should be sought from affected property owners and the relevant institutions. • Establish and enforce a strict code of conduct for all project drivers including outside suppliers delivering materials. The code should focus on safety, especially speed, and loading, especially banning all carriage of staff, workers and passengers except in seats. • Appropriate signs must be erected on the site to warn workers and community members. • The surrounding community should be sensitized on health and safety. • Ensure proper and periodic maintenance of sewer lines. • Awareness rising among community members not to dump solids in manholes. • Regular cleaning of grit chambers and sewer lines to remove grease, grit, and other debris that may lead to sewer backups. • Storage of screenings and grit in closed containers (dumpsters) instead of on the ground and ensuring that all waste is hauled off-site on a scheduled and timely basis. • Ensure appropriate covering/ventilation of the pre-treatment unit. • The perimeter of the proposed site should be vegetated with trees and plants of varying heights thereby forming windbreaker and reduce dispersion of odour. Potential Impacts risks Fire outbreak Land take Spread of HIV/AIDS Disturbance of traffic and difficulty of access Interruption of existing installations on the sewer routes Community accidents Health and safety risks from burst sewers Odor menace from sewerage treatment plant Potential Impacts Risks of overflowing manholes due to blockage of sewers Pollution of Nginyi steam Proposed Mitigation Measures • Regular inspection of the system to ensure performance is maintained at high levels. • Regular monitoring and sampling of the waste water at influent and effluent points as well as in the receiving water bodies. • Communities living within the river basins where the trunk sewers will be constructed should be enlightened on dangers of using raw sewerage to irrigate farmlands. • Arrest and prosecution of encroachers as required by Murang'a County By-laws on Way Leaves and Road Reserves. • MUSWSCO to undertake awareness campaigns aimed at preventing encroachment. • Elaborate landscaping and maintenance of these sites can limit the viewpoints to the facilities and thus reduce their visual impact. • The sludge will be temporarily held in sludge drying beds for sludge digestion and the dry cake will be safe for disposal. The dry cake can then be sold off/collected for disposal as organic fertilizer for use in local farms. Alternatively, in the event that uptake by local farmers is low, the dried sludge can be landfilled and covered with lime/earth at an appropriate location. • The quality of the discharging sewage into the river will be an important parameter on the regional control of the river eutrophication. Continuous generation and sharing of sewage quality data on pre- scheduled monitoring programmes will be necessary. of motor vehicles reg Nos.
