9 Environmental Monitoring Completion Report_No.9 ADB WWSMP

• to provide environmental data for the improvement of environmental protection measures. Wuhan Hongshan District Environmental Monitoring Station (HDEMS) conducted the monitoring for the environment, and the consultant of the H&J, Inc. USA conducted the inspections for the environmental management of the contractor of the project during the period base on the Table 3. A part of the civil of Huangpu Road WWTP (Phase II) is completed, and the rest is not start during the seven time monitoring period. The HDEMS conducted the monitoring for the environmental status of the contracts of the Luojialu Pump Station Phase II, Luojiagang Open Channel Reconstruction and Shahugang Open Channel Reconstruction etc., and inspected the environmental management of the contractors with the consultant. Table 3 Environmental Inspection Contents during Construction

Item Inspection Contents Ambient Air Mitigation Measures for construction dust and vehicles emissions Noise Noise sources: reasonable layout of construction site; are advanced construction methods conducted? are low-noise equipment used? Are noised equipment far apart from residential areas？ is noised construction stopped during night time？ Are measures taken for avoiding controllable noise? If ban construction vehicles from sounding their horns to reduce noise impact; if try best to transport material during non traffic rush hours Ecology Properly arrange the construction time; backfills are taken as soon protection as possible after completion of the earth works; brick wall should be constructed for enclosure of open-air earth and material storage places; ecological restoration, such as re-vegetation and land leveling should be conduct after completion of the contraction; conduct ecological inspection along the pipeline rout.

3.3 Routine Supervision and Inspection Base on the EMP, the environmental mitigation measures during construction are mainly for the impact from noise, vibration, dust and construction wastewater, guaranteeing expedite traffic and normal municipal facilities and vegetation recovery etc. Wuhan Hongshan District Environmental Monitoring Station, entrusted by the Consultant, conducted the monitoring for air, water and noise, as well as the sites inspections for contractors’ environmental management and implementation of the mitigation measures during the period. 3.4 Environment Management of Construction Sites All the contractors has assigned full time staff for environment management, and the environmental mitigation measures were listed as an issue of construction implementation plan; the notice boards were erected on all construction sites, on which the construction schedules, the contractors, the construction supervision companies, telephone numbers for environmental complaints, etc. were publicized. Before constructions, training were held to workers of the contractors for learning environmental knowledge, laws and regulations, as well as the EMP and the mitigation measures. 4 Conclusion and Recommendation The main reason for TSP and PM10 exceeded the standards is the dust caused by material and construction wastes transport vehicles, which also caused the noise. The mitigation measures for environment protection have been generally implemented by the contractors. The monitoring results indicated that the environmental impacts due to the constructions are acceptable.

Appendix 2 ENVIRONMENTAL IMPACT ANALYSIS 1 Introduction The Project consists of five wastewater subprojects and four stormwater subprojects. The appendix introduces the environmental monitoring and management during the implement period (2007 – December 2013), analyses the environmental impact and provide the actual issues. 2 Institutional Setup and Environmental Management Based on the requirements in the EIA and EMP of the Project, the objectives of the monitoring are: • to monitor the environmental pollution during the construction; • to evaluate extent and severity of environmental impacts compared with the predicted impacts; • to inspect contractors’ performance of the environmental impacts mitigation measures or compliance with related rules and regulations; • to answer and solve public complains; • to evaluate trends of impacts and overall effectiveness of the project’s Environmental Management Plan (EMP); and • to provide environmental data for the improvement of environmental protection measures. Wuhan Hongshan District Environmental Monitoring Station (HDEMS) conducted the monitoring for the environment, and the consultant of the H&J, Inc. USA conducted the inspections for the environmental management of the contractor of the project during the period. The environmental monitoring results during construction period have been provided to PMO, ADB and other related institutions. 3 Environmental monitoring The environmental monitoring includes: (1) everyday conducted inspect by contractor and supervisor; (2) conducted regular environmental monitoring by the local certified environmental monitoring institute. The monitoring items include waste water, surface water, noise, air and solid waste. The monitoring samples are collected and analyzed in accordance with the related environmental regulations and standards. During the construction the environmental consultant has provided the semiannual environmental monitoring report to Wuhan PMO and ADB. The TSP, PM10 and noise of some construction sites exceeded the standard. The main reason is the dust and noise caused by material and construction wastes transport vehicles.

4 Mitigation Measures Undertaken and Result The environmental mitigation measures were the important standard for the bid evaluation of each contract. This ensured that the environmental mitigation measures in EIA were properly implemented, and the construction and operation of the project improved the environment in accordance with the EIA. During construction the contractor of each subproject has implemented the mitigation measures base on the requirement. The monitoring results show that the construction has slight impact on the environmental protection receptors. 5 Environmental impact and improvement The Project improves the urban environment, public health, the life quality of urban and suburban residents, and which develops of businesses in Wuhan by improving and developing the municipal wastewater infrastructure and storm water management facilities, support the training activities and enhance the institutional construction, which will also improve the quality of surface and groundwater in and downstream of the project locations, reduce waterborne diseases and the damage of urban flooding. 6 Environmental protection acceptance The Erlangmiao WWTP_II Subproject has conducted environmental protection acceptance, and the report is shown in Appendix 3. The environmental protection acceptances of other wastewater subproject are ongoing. The storm water subprojects has slight impact on the environment, the local environmental institute don’t requirted to implement the environmental protection acceptance. 7 Conclusions The Project improves the urban environment, public health, the life quality of urban and suburban residents, and which develops of businesses in Wuhan, and improve the quality of surface and groundwater in and downstream of the project locations, reduce waterborne diseases and the damage of urban flooding.
