Q-2, r. 19 - Regulation respecting the landfilling and incineration of residual materials

Full text
32. An engineered landfill must have a system capable of collecting all biogas produced in the disposal areas and of releasing it into the environment or of directing it towards a reclamation or removal facility, so as among other things to ensure compliance with the limit values prescribed by section 60.
In the case of landfills having a maximum capacity greater than 1,500,000 m3 or sited as provided in section 24, or as soon as a landfill receives 50,000 tons or more of residual materials per year, the biogas collection system must have a gas pumping device except if such a device is not warranted because of the nature of the residual materials accepted and the low quantity of biogas likely to be produced.
In addition, if it is not reclaimed, the biogas collected in engineered landfills referred to in the second paragraph must be removed by means of thermal destruction equipment capable of destroying at least 98% of the organic compounds other than methane, or capable of reducing the concentration of those compounds to less than 20 ppm hexane equivalent, by volume, measured on a dry basis at 3% oxygen. The destruction equipment must be designed for a minimum retention time of 0.3 seconds at a minimum temperature of 760 °C. The biogas removal requirements are mandatory as long as the concentration of methane generated by the residual materials exceeds 25% by volume.
Biogas may also be removed as provided in the third paragraph using any other destruction equipment if the destruction equipment is at least as efficient as the equipment required by that paragraph and allows for continuous monitoring of its operation and for annual testing of its efficiency in destroying organic compounds other than methane.
