“The removal of the entire vegetation cover exposes the topsoil in hot weather. Besides, the soil here is very mushy and muddy when it rains, but when it dries, it hardens and forms layers.” The top soil is dry, easy to loosen and collect dust. Meanwhile, the current construction site surface is bare land, so it is easy to spread dust from the bare ground,” ACV informed.
Immediately after receiving the official dispatch from the Department of Natural Resources and Environment of Dong Nai province on urgently and seriously implementing measures to overcome dust pollution, ACV directed the units participating in the project implementation to urgently, There are many measures to overcome dust pollution caused by project construction activities.
Up to now, corrective measures have been implemented. Under the supervision of the Environmental Safety and Hygiene Team (belonging to the investor), the project construction contractor partnerships used a fleet of 35 specialized watering tank trucks to water and limit dust emissions. dispersed on the construction site (guaranteed minimum frequency of 5 times/day).
According to ACV, the unit has currently deployed 2 control gates to manage vehicles entering and leaving the construction site. ACV will require units to build and complete 2 car wash station systems at the control gates. This is to ensure that vehicles entering and exiting are washed away of mud and dirt to avoid spreading dust and soil outside the construction site.
On March 19, the Ministry of Natural Resources and Environment sent a document to ACV requesting investors to increase watering to suppress dust, especially during dry, hot, windy peak hours that can easily cause tornadoes for all buildings. The leveling area has been stripped of the covering layer.
Enterprises must regularly and continuously monitor the watering performance of construction contractors on the handed over areas; Ensure that the surface of transportation routes and areas without construction always maintain minimum humidity.
Areas with the potential to spread dust near the Long Thanh – Dau Giay expressway need to be reviewed to implement measures to minimize dust, ensuring that dust does not spread and affect traffic safety on the route. road.
The Ministry of Natural Resources and Environment emphasized the requirement for ACV to plant grass at the 722ha land storage site for areas that have reached the designed elevation; In particular, it is necessary to supervise construction contractors to ensure that transport vehicles run on the correct route and at the prescribed speed on the construction site.
