53.31.10. Unless another grouping criterion is established by the Société québécoise de récupération et de recyclage, the Société shall issue as many certifications as there are materials or classes of materials designated by the Government under section 53.31.2.
This rule does not prevent the Société from issuing more than one certification to the same body.
The Société may also issue joint certification in relation to the same materials or class of materials if the applicant bodies submit to the Société an agreement which the Société considers satisfactory as regards the manner in which the bodies are to share their responsibilities. The agreement shall specify in particular the proportion of the compensatory contribution that will be paid by each body.
