5.7 Wastewater Monitoring The Contractor Purchase commercial ready-mixed concrete without using water at the sites, therefore, there is no wastewater discharge. 5.8 Monitoring Methods and Evaluation Standard Based on the National Specifications, the standard methods of monitoring are listed in Table 9, and the evaluation standards of the monitoring for the proposed construction sites are shown in table 10 according to the environmental functional layout of Wuhan Municipality and the EIAs of the subprojects.

During the air quality monitoring, due to dust impact generated by passing vehicles, TSP and PM10 at some points exceeds the Grade II of national standard of GB3095-1996. The monitoring data of noise are as Table 12 below.

Based on the monitoring results in Table 12, the noise at the points exceeded the national standard during day time due to traffic noise. 6 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. The PMO and the construction supervision companies should stake measures to strength the supervision to contractors’ environmental management, and enforce the contractors taking the following measures: 1） Go on with implement the environmental management plan, reasonably lay out the construction equipment and schedule for mitigating the environmental impacts; 2） Using low-noise equipment, ban construction vehicles from sounding their

horns to reduce noise impact; 3） Increase water spraying of transportation routes and materials handling sites where dust is being generated; Particular attention will be paid to dust suppression adjacent to sensitive receptors such as schools or residential areas; 4） All wastes (hazardous and non-hazardous) will be removed from sites to approved waste disposal sites with the proper credentials following the appropriate standards for mitigating impacts.
