China - Zhengzhou Urban Rail Project : environmental assessment (Vol. 3) : Environmental and social management plan (Chinês)

The objective of the Zhengzhou Urban Rail Project for China is to provide an effective urban mass rapid transit system of appropriate quality in Zhengzhou along the line three corridors from XinLiu Lu station to HangHaiDong Lu station. Some of the negative impacts and mitigation measures includes: a) place the noisy machinery, such as generators and air compressors, in a closed cabin (sound insulation shed) and away from sensitive sites and keep good maintenance; minimize the usage of portable diesel engine generator without the insulation; b) plan the access roads to the construction sites on the far side of sensitive areas such as hospitals, schools, residential, and heritage buildings; c) adopt measures such as permanent relocation, temporary relocation and temporary hanging for handling of existing pipelines; the specific method shall be determined according to pipeline features, station construction method, station buried depth and other factors; d) optimize the construction program, reasonably arrange the construction time limit and minimize the noise hazard of building construction environment. During tendering and bidding of construction project, list the measures to reduce the environment noise pollution in the contents of construction organization design, and specify them in the contract signed; and e) make full use of barrier functions of non-sensitive building s such as station devices, entrance/exit and management rooms, and set them between the ventilation pavilion and sensitive buildings.
