Follow-upIf an exceedance is detected, whether during a monitoring event or at any other time, the owner or operator of the landfill shall, within 30 days after the day on which the exceedance was first detected,confirm that the exceedance has been eliminated by measuring the methane concentration at the location of the exceedance using an instrument and method referred to paragraph 19(1)(a) or (c); orprepare a plan that includesthe cause of the exceedance and a description of the measures required to eliminate it,the expected date for the completion of the measures and the reasons why it is the earliest feasible date to do so, anda description of what will be done to minimize methane emissions until the measures are completed.When exceedance to be eliminatedIf the elimination of the exceedance is not confirmed in accordance with paragraph (1)(a), the owner or operator shall eliminate the exceedance within six months after the day on which it is first detected.When exceedance considered eliminatedAn exceedance is considered to be eliminatedin relation to a surface methane concentration, if the surface methane concentration where the exceedance was detected is less than 500 ppmv; andin relation to a zone-average surface methane concentration, if the zone-average surface methane concentration in the zone where the exceedance was detected is less than 25 ppmv.
Measuring methane concentrationsSurface methane concentrations are to be measured usinga portable methane monitoring instrument thatmeets the specifications set out in sections 6.1 to 6.5 of EPA Method 21,has been calibrated in accordance with sections 7, 8.1 to 8.1.3.2 and 10 of EPA Method 21, andis maintained in accordance with the manufacturer’s recommendations, if any;a methane monitoring instrument thatmeets the specifications set out in Sections 6.1 and 6.2 of EPA OTM 51,is mounted on a drone that meets the specifications of Section 6.3 of EPA OTM 51, andis calibrated and tested in accordance with Sections 7, 8.1 to 8.1.5 and 10 of EPA OTM 51, before the instrument is first used on any day; orany methane monitoring instrument and method approved by the Minister under subsection (2).Approval of instrument and methodThe Minister may approve a methane monitoring instrument and method thatare capable of detecting the same exceedances as could be detected if the landfill were monitored in accordance with paragraph (1)(a) and subsections (3) and (5);in the case of the instrument, is capable of taking surface methane concentration measurements in accordance with subsection (5); andincludesa description of the instrument and its specifications,instructions for the operation and calibration of the instrument, the manner in which measurements are to be taken and the means by which exceedances are to be detected,instructions for the appropriate use of the instrument under various conditions,instructions for the calculation of the zone-average surface methane concentration, andif units other than ppmv are used to measure methane concentrations, instructions as to how those units are to be interpreted for the purpose of determining compliance with these Regulations.Method — paragraph (1)(a) instrumentWhen using a portable methane monitoring instrument referred to in paragraph (1)(a), surface methane concentrations are to be measured with the probe inlet placed no more than 5 cm above the landfill surface. If a measurement above 200 ppmv is takensurface methane concentrations must be measured within 5 m of the location of that measurement to identify the maximum surface methane concentration within that radius; andat the location of the maximum surface methane concentration, the probe must be maintained in a stationary position for twice the instrument response time before a measurement is taken.Method — paragraph (1)(b) instrumentWhen using an instrument referred to in paragraph (1)(b), surface methane concentrations are to be measured as follows:the drone must be flown at a constant height above ground level and at a speed such that the instrument-only response time multiplied by the forward flight speed does not exceed 4 m;during flight, using the drone’s gimballed camera, geo-referenced pictures must be taken of features that indicate elevated concentrations of landfill gas, such as distressed vegetation and cracks or seeps in the landfill cover;if a measurement above 200 ppmv is taken, within 48 hours after it is taken, surface methane concentrations must be measured within 15 m of the location of that measurement in a spiral or serpentine pattern at intervals of 3 m using an instrument referred to in paragraph (1)(a); andif a measurement above 200 ppmv is taken under paragraph (c), the surface methane concentration measurements described in paragraphs (3)(a) and (b) must be taken.Measurement locationsMeasurements are to be takenat intervals of no more than 2 m along the entire perimeter of the portions of the landfill where municipal solid waste is in place;at intervals of no more than 2 m along a pattern that traverses the landfill, at intervals of no more than 30 m that are offset by 10 m for each successive monitoring event;at all landfill cover penetrations and where indications of elevated concentrations of landfill gas are present, such as distressed vegetation and cracks or seeps in the landfill cover, using an instrument referred to in paragraph (1)(a) or (c), andif a location of concern is detected during a monitoring event, at that location as part of the next monitoring event.Excluded locationsMeasurements need not be takenin any portion of a landfill where a landfill cover or an active landfill gas recovery system is under construction; orwhere doing so poses a serious risk to human health or safety.Excluded circumstancesMeasurements are not to be taken ifthere is standing water on the landfill surface at the measurement location; orthe average wind speed measured during a 15-minute interval using an anemometer equipped with a continuous recorder and data logger exceeds 30 km per hour.
Zone-average calculation — ground-based measurementsIf surface methane concentrations are measured in a zone using an instrument referred to in paragraph 19(1)(a), the calculation of the zone-average surface methane concentration is to be based on those measurements and include only those measurements referred to in paragraph 19(5)(b).Zone-average calculation — drone-based measurementsIf surface methane concentrations are measured in a zone using an instrument referred to in paragraph 19(1)(b), the calculation of the zone-average surface methane concentration is to be based on those measurements.
