China - Shanxi Coal Bed Methane Development and Utilization Project : environmental assessment (Vol. 4) : Environmental impact assessment : Part III - pipeline project from central gas treatment station to LNG plant (Inglês)

The objective of the Shanxi Coal Bed Methane Development and Utilization Project is to increase the production and utilization of Coal Bed Methane (CBM)/Coal Mine Methane (CMM) to replace coal as a fuel for thermal use and to reduce air pollutants associated with coal combustion. The project development objective will be achieved by: (a) enhancing the sub sector's policy framework and institutional capacity; and (b) supporting the exploration, production and liquefaction of CBM to increase market access. The negative impacts of the project on the environment are as follows: (i) impact on the water carrying layers; (ii) impact of the drilling fluids on the ground water; (iii) impact of the drilling mud; (iv) domestic wastewater; (v) impact of the drilling mud on the surface water; (vi) waste gas from diesel engines; (vii) well drilling mud; (viii) rock debris; (ix) domestic garbage; and (x) noise pollution. The mitigation measures of the project are as follows: (i) store construction materials properly, take precaution measures and cover the on construction materials during rainy seasons to prevent them from being washed away by rainfall; (ii) construct construction wastewater collection pond to collect construction wastewater; (iii) construct domestic sewerage collection pond to collect domestic wastewater produced by the construction workers, which are then shipped by the sanitation department regularly to specified locations; (iv) powder-like construction materials should be properly covered to prevent dust; spray water in windy season to prevent dust; (v) construction time should be properly arranged, piling should be prohibited at night; (vi) recycle construction waste. Those that cannot be recycled should be shipped to designated landfill locations; and (vii) domestic waste should be collected and shipped to the domestic landfill site of Duanshi Town.
