GAZETTE NOTICE NO. 2589

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 Greenfield Developers Limited, is proposing to construct a thirty five storey mixed use development on plot L.R. No. 209/8760 located in Upper Hill, off .Haile Selassie Road. The proposed development will mainly comprise of office space, retail space, apartments, serviced apartments, a hotel, retail parking and associated ancillary facilities within the proposed plot. The following are the anticipated impacts and proposed mitigation measures: Positive impacts Impact Description Employment The construction and operation of the opportunities proposed Project are expected to offer employment opportunities; these range from unskilled, casual workers, semi- skilled and formal employees. Impacts on local and • Gains in the local economy will result national economy from the utilization of locally available - materials including: building stones, iron sheets, timber, bricks, paint, electrical cables, water storage equipments, water pipes, steel, glasses, fencing posts, sand, cement, fuels, etc. and paying of taxes to the government. Optimal land use Change in land use from underutilized land to land on which a modem high-rise development stands - - will optimize land use in the area. Improved infrastructure • The operation of the proposed Project may induce improvements in • infrastructure around the facility e.g. improved roads, electricity connection, regular maintenance of roads, storm - water drainages and power lines around the building and environs. Noise and vibrations Comply with maximum permissible generation noise levels for constructions sites as per Second Schedule of the Environmental Management and Co- ordination (Noise and Excessive Vibration Pollution ,, Control) Regulations, 2009; apply for a license from NEMA whereby maximum permissible noise levels are to be exceeded; Prescribe noise reduction measures e.g. restricted working hours, transportation hours and noise buffering; Install portable barriers to shield compressors and stationary equipment where necessary and locate stationary noise sources as far from existing sensitive receptors as possible; Use quiet equipment (i.e. equipment designed with noise control elements such as mufflers). Air pollution (dust and • Provide 2.4 meter high hoarding along exhaust emissions) site boundary; Provide effective dust screen, sheeting or netting where a scaffolding is erected around the perimeter of a building under construction, from the ground floor level of the building, or if a canopy is provided at the first floor level, from the first floor level, up to the highest level of the scaffolding; Any skip hoist for material transport shall be totally enclosed by impervious sheeting; Water all active construction areas when necessary; Cover all trucks hauling soil, sand and other loose materials or require all trucks to maintain at least two feet of freeboard; Pave, apply water when necessary, or apply (non- toxic) soil stabilizers on all unpaved access roads, parking areas and staging areas at construction site; Down wash of trucks (especially tyres) prior to departure from site; Use of electrically operated construction machinery to avoid externalities produced by diesel engines. Health and safety risks • Security shall be enhanced by ensuring security guards Are always posted within and around the project site and strategic placement of security lights around the site; a roster of all construction workers shall be kept while measures shall be put in place to ensure that loitering by itinerant workers is discouraged; unattended public access to the construction site shall be restricted and only one entry/exit point shall be used; Appropriate health and safety measures shall be implemented as per the OSHA Act 2007; warning signs should be placed in appropriate places; Safety education and training of the construction workers should be undertaken; appropriate personal Protective Gear shall be worn at all times by all within the construction site including visitors; Install appropriate fire management equipment Deep trenching/ A barricade at least 3 feet high must be excavation risks erected around a trench that is I meter or more deep excavated material should not be placed less than 4 feet from the edge of a trench to minimize risk of collapse due to the weight of the spoil; where a possibility of collapse or cave of an excavation exists, it should be shored, shielded, benched or battered to prevent the collapse or cave-in; ladders must be provided no more than 20 meters apart in the area where excavation works are being carried Out. Soil erosion and water • Terrace, level and rip off compacted logging areas of the project site to reduce run-off velocity and increase infiltration of storm water into the soil; dig trenches and cut off drains to channel- runoff into existing peripheral storm water drains; Surface runoff should be harvested where applicable for reuse during construction works. Waste generation • Use durable, long-lasting materials that will not need to be replaced 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 packaging to avoid the generation of excessive packaging waste; use construction materials containing recycled content when • possible and in accordance with accepted standards; Ensure adequate collection and storage of waste on site - and safe transportation to licensed disposal sites by licensed waste handlers. Increased traffic Any work that disturbs normal traffic signal operations shall be coordinated with the relevant authorities; Ensure that the Entry/Exit to the project site is located where it will cause minimal traffic along Haile Selassie and Lower Hill Roads; Ensure all construction vehicles to and from the construction site use the designated Entry/Exit to the project site. • All transportation of construction raw materials and excavated materials are to be conducted at traffic off peak hours only; Cover all trucks hauling soil, sand and other loose -materials to avoid spillage and dust emissions that may interfere with smooth motoring; "NO PARKING" signs will be posted around the building where Parking is prohibited and likely to cause obstruction as well as other necessary traffic signs; Traffic management/parking personnel shall be provided to monitor parking and ensure smooth motoring along the buildings adjacent roads. - Increased water demand • Promote -awareness on water conservation and reducing water wastage. • Reduce water delivery in taps, through the installation of low flow devices or aerators on taps; Press action taps, flush valves and urinal sensors shall be used to minimize water wastage in public washrooms; Install water efficient plumbing. Increased energy demand • Improve lighting efficiency by efficient window placement during project design (day-lighting); Identify and use equipment/systems having minimum energy consumption; Audit energy use occasionally; Use alternative energy sources such as solar power; Other - mitigation measures are outlined within the report.
