Appropriate Dust and Stockpiling Measures for Middle East

Most of the LEED projects currently constructed in the Middle East are facing serious challenges complying with EPA requirements with regards to dust suppression, stockpiling and crushing activities. Large volumes of water is being wasted for dust suppression with little effect on actual site conditions. Once the trafficable routes have been sprayed with water, it takes less than half an hour to dry up. Water tankers are spraying water around the clock to comply with the requirements of CAPP prerequisite. Considering how scarce water is in countries like Qatar, UAE, and KSA, we are not sure this is the best option. Another challenge is stockpiling on site. It is a standard practice to cover stockpiles with green mesh/tarpaulins or spray them with water. Some of these projects are massive with enormous amounts of stockpiles and hence impractical to cover them. They are currently being sprayed with water – very large amounts of water. As far as rock crushing activities is concerned, large amounts of water are also being used for dust suppression. Would it be possible to implement other measures to reduce the amount of water used for dust suppression? Thank you in advance
