138. The operations at a transfer station involving the loading and unloading of residual materials must be carried out inside a building. No residual material may be stockpiled outside the building. No truck containing residual materials may be parked on the premises of the transfer station for a period of more than 1 hour.
When transfer activities cease for a period of more than 12 hours, all the residual materials received must be conveyed to their destination so that no residual materials remain inside the building or on the premises of the transfer station. That requirement does not apply if the building referred to in the first paragraph has an air collection and treatment system that prevents any nuisance odour caused by the residual materials remaining in the building for a period of more than 12 hours.
