20. An inventory estimating the volume of the timber felled but not yet scaled or declared on the last day of a calendar month must be sent by the person or body referred to in the first paragraph of section 1 to the Minister every month so that the Minister receives it not later than the fifth working day of the month following the month for which the inventory was made.
The inventory must indicate the location of the timber included in the inventory, be entered on a form complying with the model drawn up for that purpose by the Minister and be signed by a culler. It is used to determine, on the basis of written data, the volume harvested until the timber is scaled and the scaling data is declared to the Minister.
