Landfill Methane Regulations — 1
Definitions 1 (1) The following definitions apply in these Regulations. active landfill gas recovery system means any system that employs landfill gas recovery wells, piping, blowers, fans, pumps or compressors to create a pressure gradient to actively extract landfill gas. ( système de récupération active de gaz d’enfouissement ) authorized official means (a) in respect of an owner or operator who is an individual, that individual or another individual who is authorized to act on their behalf; (b) in respect of an owner or operator that is a corporation, an officer of the corporation who is authorized to act on its behalf; and (c) in respect of an owner or operator that is an entity other than a corporation, an individual who is authorized to act on its behalf. ( agent autorisé ) biocover means a landfill cover that is designed to support microbial oxidation of methane via the aerobic pathway. ( biocouverture ) closed , in relation to a landfill, means that the landfill has permanently ceased to accept solid waste for disposal. ( fermé ) EPA Method 21 means the method of the Environmental Protection Agency of the United States entitled Method 21 — Determination of Volatile Organic Compound Leaks , set out in Appendix A-7 to Part 60 of Title 40, chapter I of the Code of Federal Regulations of the United States. ( méthode 21 de l’EPA ) EPA OTM 51 means the method of the Environmental Protection Agency of the United States entitled Other Test Method 51 (OTM-51) - UAS Application of Method 21 for Surface Emission Monitoring of Landfills . ( autre méthode 51 de l’EPA ) equipment component means any part of a landfill gas management system that contains landfill gas including wells, pipes, flanges, fittings, valves, flame arrestors, knock-out drums, sampling ports, blowers, compressors and connectors. ( composant d’équipement ) exceedance means, in relation to (a) a surface methane concentration, a concentration of 500 ppmv or more; and (b) a zone-average surface methane concentration, a concentration of 25 ppmv or more. ( dépassement ) final cover means a landfill cover that is placed on the portions of a landfill where acceptance of solid waste for disposal has permanently ceased. ( couverture finale ) landfill gas means a mixture of gases, including methane, generated by the decomposition of biodegradable waste in a landfill. ( gaz d’enfouissement ) landfill gas management system means a system used in a landfill to recover and combust or process landfill gas. ( système de gestion de gaz d’enfouissement ) location of concern in relation to a surface methane concentration, means a location with a concentration of at least 200 ppmv but less than 500 ppmv. ( emplacement préoccupant ) methane leak means a methane leak with a methane concentration of 500 ppmv or more. ( fuite de méthane ) methane modelling tool means the Landfill Methane Modelling Tool published by Environment and Climate Change Canada for the calculation of methane generation at Canadian landfills. ( outil de modélisation du méthane ) monitoring event means, as the case may be, each of the monitoring events in relation to (a) landfill gas recovery wells required under subsection 10 (1); (b) equipment components required under subsection 13 (1); or (c) surface methane concentrations and zone-average surface methane concentrations required under subsection 17 (1). ( activité de surveillance ) municipal solid waste means waste that originates from residential, commercial, institutional, construction, renovation, demolition or land clearing sources. ( déchet solide municipal ) operator means a person that has the charge, management or control of a landfill or a landfill gas management system. ( exploitant ) ppmv means parts per million by volume. ( ppmv ) vent means to passively emit landfill gas to the atmosphere via vent pipes. ( évacuation ) zone-average surface methane concentration means the average of all methane concentrations recorded within a specified zone of
