EIS on completion engineering for Southern Sewer Project of Bailonggang sewerage system

The Shanghai Urban Environment Project for China is intended to provide a sustainable environmental setting for the long term economic and social development in the Municipality of Shanghai while supporting the provision of urban infrastructure. The project environmental negative impacts follow: soil, waste water, pollution, air quality noise, dust, and traffic. Mitigation measures include: (i) covering temporary soil stock piles; (ii) minimizing active excavation area during pipe trenches; and (iii) installation of sediment fences where appropriate to minimize sediment runoff. Disturbed surfaces, such as re-compacted pipelines trenches, will be re-vegetated to minimize erosion. Soil contamination may be cased by inappropriate storage and disposal of hazardous construction materials. Especially for wastewater component Bailonggang Southern Collector Extension Project will spread across 17 local rivers, of which the Pudong Channel and Cuanyang River have a navigation function, other rivers perform a flood protection function. During project construction, advanced technology - pipe jacking technology will be used, with no impact to the rivers function. Water will be sprayed transportation routes and material handing sites where dust is being generated. Particular attention will be paid to dust suppression adjacent to sensitive receptors such as schools or residential areas. Material will be stored in appropriate places and covered sprayed to minimize dust. Material will be covered during transportation to avoid spillage or dust generation. Air pollution may be caused by emissions from vehicles and construction machinery. Vehicles and construction machinery will be properly maintained and will comply with emission standards. Construction materials and waste will be stored in secure, covered areas with secondary containment. All waste will be removed from sites to approved waste disposal sites. There will be no on-site landfills at any of the construction sites. Construction waste will be promptly removed from the sites, and the burning of waste will be prohibited.
