161. As of the expiry date of the 3-year period following 19 January 2006, and subject to the second, third and fourth paragraphs, the sanitary landfill sites, in-trench disposal sites for solid waste and dry materials disposal sites referred to in section 157 are, except with respect to siting standards, governed by the provisions of this Regulation that apply respectively to engineered landfills, trench landfills and construction or demolition waste landfills as regards the acceptance of residual materials and the conditions for the development, operation, closure and post-closure management of the disposal areas or trenches in which residual materials will be landfilled as of the date mentioned above. The first paragraph of section 18 requiring the creation of a buffer zone does not apply to leachate or water treatment systems, gas pumping devices or biogas removal facilities in existence on 19 January 2006. In addition, in the case of the landfill used exclusively by the waste water treatment plant of Ville de Montréal in operation on that date, the minimum width of the buffer zone prescribed by the first paragraph of section 18 is reduced to 10 m around the landfill, including any future enlargement, so long as only the ash from the sludge incinerator and the sands generated by the operation of that station are landfilled.
In addition, after the expiry of the 3-year period following 19 January 2006, residual materials may be accepted in in-trench disposal sites for solid waste existing on 1 May 2000 only if the sites are located in a territory described in section 87 which at all times meets the requirements of subparagraphs 2 and 4 of that section, and the landfilling is done in trenches that meet the siting standards prescribed by section 88.
Similarly, after the expiry of the 3-year period mentioned above, construction or demolition waste may be accepted at dry materials disposal sites existing on 1 May 2000 only if the sites meet the requirements of section 103 and the landfilling is done in disposal areas that meet the siting standards prescribed by section 104. The siting standards do not apply to disposal areas if their siting complies with the provisions of this Regulation that apply to containment and the collection of leachate in engineered landfills.
A landfill referred to in the second or third paragraph, or a disposal area or a trench in such a landfill, must be permanently closed as soon as residual materials may no longer be accepted owing to non-compliance with those paragraphs.
Despite the provisions of the second and fourth paragraphs of this section, residual materials generated in the territory of Ville de Lebel-sur-Quévillon remain accepted in the in-trench disposal site operated by the municipality before 19 January 2009 and located in the territory of Ville de Senneterre, up to the landfill capacity authorized on that date so long as it is sited and operated in accordance with the provisions prescribed by sections 88 to 93.
