Could anyone kindly clarify the following issue:
I work with a project on construction of industrial plant. Prior to construction activities the topsoil was completely removed from the site leaving underlying soil layer exposed. Since this layer consists of sand only (a few tens of meters deep) and construction activities take place on 99.9% of the site area, I have at least 3 questions that I struggle to find answer to:
1. Stabilization of soil. Are there any measures that are relevant to this case?
2. Dust control. Sprinkling is adopted for the project to prevent erosion and air pollution. What more can be done?
3. Since an access to the construction site is provided by a 600m (away from paved road) stretch of gravel/dirt road, does it make any sense to minimize sediment track-out (as in art.2.1.2.3 EPA CGP)?
Thank you very much.

1. Soils stabilization. Standard practice is to really only strip the topsoil far a few days worth of work. Typically 3. If the entire site is stripped, any areas to be open for longer than 3-4 days should be seeded and stabilized with hay at a rate of at least 1 ton per/acre, this will achieve approximately 87% less soil loss than an unprotected area. 2 tons will get you about 98.
2. On-site water is really the only thing you can do.
3. A construction entrance is typically larger d50 stone than ordinary gravel. A gravel drive is not going to be very effective.
