GAZETTE NOTICE NO. 14082

Pursuant to regulation 21 of Environmental (Impact Assessment and Audit) regulations, the National Environmental Management Authority (NEMA) has received an Environmental Impact Assessment Study Report for the implementation of the proposed boundary wall, storey units, market stalls, bridges and footpaths. The project involves the construction of boundary wall, 1490 residential and 1539 business relocation units, market stalls, bridges and footpaths. THE KENYA GAZETTE 4th November, 2011 4288 4288 The project area stretches from the 534/6 km mark to the 539/9 km mark within the Nairobi- Kibera section (5.3 Km) and Likoni Road to Mombasa Road within the Makadara- Embakasi section (7 Km) totaling some 12.3 Kilometers. The following are the anticipated impacts and proposed mitigation measures: Environment al/Social Issue Management & Mitigation and /or Enhancement Measures Oil spillage Materials spillage Littering the site Ensure no spillage occurs Ensure use serviceable machinery Ensure no littering of the compound Ensure safe storage of materials Ensure accurate budgeting and estimation of actual construction material requirements to ensure that the least amount of material necessary is ordered. Ensure that damage or loss of materials at the construction site is kept minimal through proper storage. Use at least 5%-10% recycled refurbished or salvaged materials to reduce the use of raw materials and divert material from landfills. Vegetation disturbance Ensure proper demarcation and delineation of the project area to be affected by construction works. Specify locations for vehicles and equipment, and areas of the site which should be kept free of traffic, equipment, and storage. Designate access routes and parking within the site. Introduction of vegetation (trees and grass) on open spaces and around the project site and their maintenance Design and implement an appropriate landscaping programme to help in revegetation of part of the project area after construction. Increased storm water, runoff and soil erosion Surface runoff and roof water shall be harvested and stored in reservoirs so that it can be used for wetting and/or cooling purposes. A storm water management plan that minimizes impervious area infiltration by use of recharge areas and use of detention and/or retention with graduated outlet control structure will be designed. Apply soil erosion control measures such as levelling of the project site to reduce run-off velocity and increase infiltration of storm water into the soil. Apply soil erosion control measures such as levelling of the project site to reduce run-off velocity and increase infiltration of storm water into the soil. Ensure that construction vehicles are restricted to use existing graded roads Ensure that any compacted areas are ripped to reduce run-off. Site excavation works to be planned such that a section is completed and rehabilitated before another section begins. Interconnected open drains will be provided on site. Roof catchments will be used to collect the storm water for some office uses. Construction of water storage tanks to collect storm water for office and plant uses. Increased solid waste generation Use of an integrated solid waste management system i.e. through a hierarchy of options: 1. Reduction at source 2. Recycling 3. Reusing 4.Incineration 5. Sanitary landfilling. Through accurate estimation of the dimensions and quantities of materials required. Use of durable, long-lasting materials that will not need to be replaced as often, thereby reducing the amount of construction waste generated over time Provide facilities for proper handling and storage of construction materials to reduce the amount of waste caused by damage or exposure to the elements Use building materials that have minimal or no packaging to avoid the generation of excessive packaging waste metal and plastic containers to reduce waste at site Dispose waste more responsibly by contracting a registered waste handler who will dispose the wastes at designated sites or landfills only. Waste collection bins to be provided at designated points on site Air Pollution Ensure strict enforcement of on-site speed limit regulations. Regularly watering access roads and borrow pit sites in close proximity to human settlements during the dry season in order to suppress dust generation and particulate settlement Avoid excavation works in extremely dry weather. Mixing should not be done on windy location All access roads and work areas to be regularly sprinkled with water Sprinkle water on graded access routes when necessary to reduce dust generation by construction vehicles Personal Protective equipment to be provided to employees (breathing protection gear) Noise and Vibration Sensitise construction vehicle drivers and machinery operators to switch off engines of vehicles or machinery not being used. Sensitise construction drivers to avoid reversing of vehicle engines or hooting Ensure that construction machinery is kept in good condition to reduce noise generation. Limiting the extraction of gravel from borrow pits to normal working hours as legally provided for by Kenyan Laws and not outside 7:00 to 18:00 hours; Ensure that all generators and heavy duty equipment are insulated or placed in enclosures (containers) to minimize ambient noise levels. Trees to be planted around the site to provide some buffer against noise propagation The noisy construction works will entirely be planned to be during day time when most of the neighbours will be at work Increased energy consumption Ensure electrical equipment, appliances and lights are switched off when not being used Install energy saving bulbs/tubes at all lighting points instead of incandescent bulbs which consume higher electric energy Plan well for transportation of materials to ensure that fossil fuels (diesel, petrol) are not consumed in excessive amounts Monitor energy use during construction and set targets for reduction of energy use. High Water Demand Water to be brought in from the City Water and Sewerage Company Harness rainwater for office & gardening Install water conserving taps that turn-off automatically when water is not being used Promote recycling and reuse of water as much as possible Install a discharge meter at water outlets to determine and monitor total water usage Promptly detect and repair of water pipe and 4th November, 2011 THE KENYA GAZETTE tank leaks Sensitise construction workers to conserve water by avoiding unnecessary toilet flushing etc Ensure taps are not running when not in use Generation of wastewater Provide means for handling/treating sewage generated at the construction site Provide means for handling/treating sewage generated at the construction site Monitor effluent quality regularly to ensure that the stipulated discharge rules and standards are not violated Ensure compliance with The OSHA (Building Operations and Works of Engineering Construction Rules), L.N. 40 of 1984 Human Health And Safety. Sensitizing local communities not to allow children to play in flooded borrow pits during the rainy season; Conducting indoor spraying for mosquitoes. Conducting an awareness campaign covering construction equipment operators at borrow pits and the local community on matters of HIV/AIDS Oil spills Install oil trapping equipments in areas when there a likelihood of oil spillage such during the maintenance of construction equipment. Soil in such an area will be well protected from contamination Social and Economic Effects Compensation and Relocation Plan to take into account compensation for loss of location shelter, trading stalls, crops and other structures. Limiting borrow pit sites to infertile and uncultivated pieces of land as much as is possible and Compensating individuals for any losses incurred to personal property as a result of the operation of the borrow pits. Enhance consultations with the locals on the activities affecting them and include them on impact reduction Solid waste generation Provide solid waste handling facilities such as waste bins and skips Ensure that solid waste generated at the proposed development is regularly disposed of appropriately at authorized dumping sites Ensure that occupants of the proposed development manage their waste efficiently through recycling, reuse and proper disposal procedures.
