Pakistan - Highway Rehabilitation Project : sectoral social and environmental assessment (Vol. 5) : Rehabilitation and maintenance projects, phase I - environmental management plan (English)

This environmental assessment for the Pakistan highway Rehabilitation Project outlines the following mitigation measures to address the environmental and social concerns expressed during public consultation: Demarcate wasteland or natural areas with a high elevation for borrowing earth material to prevent loss of fertile plough layer at campsites and asphalt plants and a drop in the elevation of borrow areas. Limit earth excavation; strip topsoil and stockpile for redressing the land, including filling deep ditches; protect low embankments from erosion by planting indigenous grasses able to flourish under dry conditions; construct stone pitching or a riprap across high embankments to reduce dust emissions, a fall in land productivity, and possibly silting of nearby water bodies; and landscape ditches and borrow pits to avoid hazards to people and animals. To control pollution to air, surface and subsurface water resources, and soil, distance project facilities from settlements, wildlife habitats, and cultural monuments; equip plants with dust control devices such as fabric filters or wet scrubbers; locate camps in natural drainage channels to facilitate the flow of treated effluents; pass wastewater effluents through gravel/beds to remove oil/grease contaminants before discharging it into natural streams; train the workforce in storing and handling hazardous materials and chemicals; treat and dispose of solid waste in designated waste disposal sites; recycle debris; and use impervious layers when disposing of scarified/scraped asphalt in borrow pits. Compensate for vegetative loss by replanting; and setting up facilities on barren land and confining construction vehicles. To lessen impacts on the drainage system, design drains to lead to safely dispose of run-off; ensure adequate waterways; prevent earth and stone from blocking cross-drainage structures; carry out retention work; periodically clear drainage structures. Reduce impacts on cultural sites and community-owned assets by minimizing waste; resolve conflicts related to water usage; raise the level of boundary walls to lower noise and limit construction to daylight hours. Provide for highway safety by improving intersections, using traffic control devices, building public facilities such as bus bays with passenger waiting sheds and latrines, diverting traffic, displaying warning signs, initiating a safety awareness campaign, and preparing traffic management plans.
