Based on the monitoring results in Table 12, the noise at the points nearby Jinshan Avenue of Dongxihu Three Gates Connection Project, and the point nearby Jingzhu Expressway of Caidian WWTP Project exceed the national standard during day time due to traffic noise, but other points meet the standard (Grade II) during both daytime and nighttime. 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.
