38. Residual materials received for landfilling in an engineered landfill must be weighed and undergo radiological testing by devices capable of detecting the presence of radioactive materials.
The devices for weighing the residual materials and for testing the residual materials for radioactivity must be installed at the entrance to the site, be used and maintained so as to provide reliable data and be calibrated at least once a year.
The provisions of this section regarding the weighing of residual materials do not apply to a landfill reserved exclusively for the use of an industrial, commercial or other establishment if the data relating to the quantity of residual materials (in weight) that are landfilled may be obtained otherwise and under the same conditions of accessibility and conservation as those set out in section 39.
Similarly, the provisions of this section regarding the testing of residual materials for radioactivity do not apply to the landfill referred to in the third paragraph if, by reason of the nature of the activities of the establishment using the landfill and the composition of the residual materials landfilled, the residual materials cannot contain any radioactive material.
