Environmental management plan for urban works rehabilitation

The main objective of the Emergency Monrovia Sanitation Project for Liberia is to ensure environmental protection and management in addition to providing assistance in the design, facility construction, site preparation, operation, and post closure of the proposed facility. This Environmental Impact Assessment (EIA) will target land filling activities as well as highlight various facility management plans to be implemented by the contractor during all phases of the project. Negative impacts include: noise pollution from construction equipment; soil contamination from accidental spill of oil, paints, lubricants; soil erosion and modification of surface relief; surface and groundwater contamination from surface runoff; loss of flora from fauna from construction activities and oil spill; traffic congestion; odour and possible loss of aesthetic due to piling of construction wastes, excavated soils and solid waste debris; and respiratory diseases from dust. Mitigation measures include: 1) sprinkle water on soil to prevent dust generation; 2) construction equipment will strictly conform to international noise standards; 3) burrow pit shall be covered or backfilled to avoid stagnant water bodies; 4) dispose all waste at permitted points to avoid leaching and soil contamination; 5) construct treatment/retention pond for storm water, wash-water from at site during construction; 6) traffic management prescribed and performed equipment cleaning and wastewater from camp site and construct good drainage in accordance with the local laws with appropriate measures and signaling systems (e.g., appropriate lighting, traffic safety signs, barriers and flag persons) that are easily seen or easy to follow; 7) dispose off environmental harmful materials (asbestos sheet) in an appropriate legal and safe manner and proper disposal of waste material at appropriate location specified by local authorities; and 8) provide workers with safety instructions and protective equipment as required by local laws.
