44. In order to protect the air, water and soil from contamination, contaminated soils cannot be stored in a transfer station elsewhere than inside a building constructed in such manner as to protect its contents from alteration by water, snow, freezing or heat. The floor of the building must be of impermeable material not likely to be damaged by the nature of the contaminants present in the soils and be capable of supporting the soils. In addition, the storage area must be laid out so that any run-off liquid is contained.
The building must be ventilated so that it is maintained at all times under negative air pressure. The ventilation system must enable all the substances present in the gases and dust likely to be released from the building to be collected and sampled, and a gas treatment system must be installed so that all the substances discharged into the atmosphere comply with the ambient air standards at all times, at the limits of the property.
