GAZETTE NOTICE NO. 11220

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, Tononoka Rolling Mills Limited, proposes to install a hot structural section mill in addition to the existing rolling mill. The project entails the construction of office blocks, oxygen plant, a melting shop, fuel storage plant and a scrap shed. The proposed project will be located on Plot No. 12034/2, off Komarock Road, Dandora, Embakasi-North Sub-county, Nairobi City County. The following are the anticipated impacts and proposed mitigation measures: Possible Impacts Mitigation Measures Air pollution • All personnel working on the project will be trained prior to starting construction on methods for minimizing air quality impacts during construction. • Construction vehicle drivers will be under strict instructions to minimize unnecessary trips, refill petrol fuel tanks in the evening and minimize idling of engines. • All active construction areas will be watered at least twice a week to reduce dust. • All trucks hauling soil, sand and other loose materials shall be covered. • Traffic speed of construction/other vehicles will be restricted to a maximum of 15 mph. • Provide all workers with PPEs and enforce their use. • Careful screening of construction site to contain and arrest construction-related dust. • Vegetation will be replanted in disturbed areas as soon as possible to create green space and stabilize soils. • Exposed stockpiles of e.g. dust and sand, will be enclosed, covered, and watered daily, or treated with Non-toxic soil binders. 7228 7228 Possible Impacts Mitigation Measures • Excavation and grading activities will be suspended when wind speed exceeds 25 mph. • Windbreakers will be installed at the windward side of the construction site. • All workers on the site will be required to wear protective clothing while on duty. Modification of micro –climate • Careful layout and orientation of the plant and buildings to respect microclimate: wind and sun direction. • The project will use minimum reflective building materials and finishes for roof, walls and paving. • Harmonize site drainage design with neighbouring premises. Noise pollution • Portable barriers will be installed to shield compressors and other small stationery equipment where applicable. • Encourage use of manual labour where appropriate. • Use of equipment designed with noise control elements will be adopted where necessary. • Trucks used at construction site shall be routed away from noise sensitive areas in the neighbourhood, where feasible. • Sound barriers are to be installed for pile driving activities. • Idling time for pick-up trucks and other small equipment will be minimized to limited time. • Use of very noisy equipment will be limited to daytime only. • All workers operating in noisy areas or operating noisy equipment will be provided with earmuffs to protect against extreme noise. • Construction works to be carried out during daytime only. Loss of biodiversity and Soil disturbance, erosion • Limit excavation to marked project areas. • Refilling and paving to limit impacts on soil. • Provision of earth bunds or sand bags in areas where a large amount of exposed soils exists would be required. • Proper waste disposal to avoid contamination of natural environment. • Define areas for greening and rehabilitate to NEMA approval. Water quality pollution • Plan emergency procedures in case of accidents, or spills of pollutants. • Keep natural water channels free from obstruction. • Define safety rules for work site. • Storm water management plan that minimizes impervious area increases infiltration by use of recharge areas, and use of retention, and/or retention with graduated outlet control structures, will be used. • Maintain internal and immediate external drainage systems clear all the times. • Compact loose soils and apply non-toxic Possible Impacts Mitigation Measures binding materials. • Undertake roof catchment harvesting to reduce volumes of storm water. • Dispose liquid waste appropriately. Solid waste • Wastes to be collected regularly to control air pollution and vermin/insects etc. • Receptacles will be provided for waste storage prior to collection. • Resource recovery will be encouraged once the project takes off so as to shrink waste stream and recover non-recyclables. • Refuse collection vehicles will be covered to prevent scatter of wastes by wind. • Wastes will be collected by a licensed operator to avoid illegal final dumping at unauthorized sites. • All persons involved in refuse collection shall be in full protective attire. • For hazardous waste- In case of spillage emergency spillage control measures to be instituted. • Containerization of any hazardous wastes and disposal through a licensed waste handler. Occupational health and safety • Conduct regular training on work safety procedures. • Proper storage and handling of flammable substances. • Appropriate signage. • Enforcement of PPEs. • A comprehensive contingency plan will be prepared before construction begins, on accident response. • Accordingly, adherence to safety procedures will be enforced. • All workers, pursuant to labour laws, shall be insured against accidents. • All workers will be instructed to wear protective clothing during construction, including helmets. This would be enforced to ensure compliance. • Construction work will be limited to daytime only. Impacts on water and energy resources • Collect and treat all wastewater for reuse. • Consider rainwater harvesting to augment the NAWASCO and borehole water supply. • Reuse recycled water as much as possible with proper treatment procedures. • Routinely undertake surface water quality monitoring. • Undertake energy audits every 3 years. • Implement 50% recommendations of audit before next audit. • Consider capture of heat and gas from processes to supplement energy requirements of the project. • Use energy efficient equipment on site Air emission • Develop and implement BMPs within the plant to minimize gaseous emissions. 16th September, 2022 THE KENYA GAZETTE Possible Impacts Mitigation Measures • Maintain good housekeeping . • Monitor air quality for chimney stacks and ambient air quality and undertake regular air quality analysis. • Regularly monitor piping systems to ensure no leakage of gases, fuels. • Adopt a combined strategy including a reduction in energy demand, use of cleaner fuels, and application of emissions controls. • Develop a green belt around the project site to absorb toxic emissions and carbon dioxide. • Establish a community liaison to monitor the effects of project activities on people around the project. • Cooling tower should be maintained for prevention of growth of Legionella bacteria. • Paves all areas on site and grade access road to site. • Mill scale from rolling processes should be stored in within contained premises to prevent air dispersions into neighbourhood. • Undertake annual emission analysis according to the Air Quality Regulations and submit report to NEMA and DoSHS. Waste water generation • Treat all waste water arising from processes prior to reuse. • Ensure treated waste water meets relevant standards in Water Quality Regulations. • Undertake regular effluent analysis. • Ensure all sanitary liquid is discharged into the public sewer. • Where applicable ensure a sewer discharge license is obtained. • Capture and contain runoff water from the storage area for treatment before release to the environment. • Install oil traps at storm drain exit points. • Pass any sludge produced through a filter press and dry in impermeable sludge drying beds prior to disposal. • Dispose Sludge thorough licensed hazardous waste handlers. • Undertake regular (waste) water analysis to ensure efficacy of the treatment plant. • Put in place a monitoring program to ensure liquid waste from the plant is managed accordingly. Climate change • Undertake an intensive greenhouse gas inventory to monitor GHG emissions. • Develop and implement a GHG data management system. • Consider converting waste heat into electricity. • Include and maintain plant greenbelts and participate in tree planting activities to act as carbon sink. • Include climate change prevention measures in environmental policy and sensitize workers on importance of adherence to the measures. Traffic and transport • Undertake transport activities during the Possible Impacts Mitigation Measures day. • Provide a traffic flow management plan to avoid traffic congestions and accidents.
