Reducing manure methane emissions (protocol version 1.0)

Foreword

Canada’s Greenhouse Gas (GHG) Offset Credit System is established under Part 2 of the Greenhouse Gas Pollution Pricing Act to provide an incentive to implement projects that result in domestic GHG reductions that would not have been generated in the absence of the project, that go beyond legal requirements and that are not subject to federal or provincial pricing mechanisms for GHG emissions.

Canada’s GHG Offset Credit System consists of:

Only projects following a federal offset protocol included in the Compendium and meeting all requirements outlined in the Regulations can generate GHG reductions for which federal offset credits may be issued under the Regulations.

1.0 Introduction

Methane emissions from livestock manure are primarily generated by anaerobic decomposition of organic matter in liquid manure in an anaerobic storage structure. Implementation of manure treatment systems (MTS) for liquid manure can reduce these methane emissions by reducing the amount of manure methane produced during storage.

The Reducing Manure Methane Emissions federal offset protocol is intended for use by a proponent implementing a project that treats eligible manure with one or more eligible MTS in order to generate greenhouse gas (GHG) emission reductions for which federal offset credits may be issued under the Canadian Greenhouse Gas Offset Credit System Regulations (the Regulations). The following are eligible project MTS:

The proponent must follow the quantification methodology and requirements set out in this protocol, including those to quantify and report GHG emission reductions generated by eligible project activities. The requirements contained in this protocol are part of the Regulations and must be read in conjunction with provisions in the Regulations.

This protocol is designed to ensure a project generates GHG emission reductions that are real, additional, quantified, verified, unique and permanent. The protocol is also developed in accordance with the principles of ISO 14064-2:2019 Greenhouse gases – Part 2 – Specification with guidance at the project level for quantification, monitoring and reporting greenhouse gas emission reductions or removal enhancements to ensure reported GHG emission reductions generated as a result of implementing a project are relevant, complete, consistent, accurate, transparent, and conservative.

A project that uses biogas produced by an anaerobic digestion system instead of fossil fuels to produce energy may also generate GHG emission reductions from fossil fuel displacement (that is, fuel switching). However, when the GHG emission reductions are from sources that are subject to a federal or provincial pricing mechanism for GHG emissions, GHG emission reductions from fossil fuel displacement are not additional and are not eligible for federal offset credit issuance.

The proponent is also responsible for ensuring that any GHG emission reductions credited under Canada’s GHG Offset Credit System are unique, that is, they are not credited under another offset program or another GHG reduction mechanism.

3.0 Baseline scenario

3.1 Baseline conditions

For a project to be eligible under this protocol, at least one of the following baseline conditions must be met at the project site:

In addition, for any livestock operation, the following baseline conditions must be met for at least 10 years before the project start date or, if the livestock operation was established less than 10 years before the project start date, since its establishment:

3.2 Determining the baseline scenario

The baseline scenario for a project implemented following this protocol is the release of manure CH4 to the atmosphere from anaerobic storage of eligible manure. GHG emissions from the anaerobic storage of eligible manure that would have occurred in the absence of the project (baseline scenario) are quantified using a dynamic baseline approach, as per Section 8.1.1.

In addition, where an AD MTS is part of a project and produces biogas eligible for fossil fuel displacement, as per Section 4.4, and the proponent chooses to quantify the resulting GHG emission reductions for federal offset credit issuance, the proponent must determine the type and the annual amount of fossil fuels that would have been used in the baseline scenario. The proponent must quantify these baseline scenario GHG emissions as per Section 8.1.2.

4.0 Project scenario

4.1 Project conditions

To be eligible under this protocol, a project must meet the following project conditions:

A project MTS may treat any feedstock, but only eligible manure can generate GHG emission reductions from anaerobic storage under this protocol.

Structures storing eligible manure may have been installed and operated prior to January 1, 2017.

4.2 Eligible manure

Manure that is to be treated in a project must meet the following conditions to be considered as eligible manure under this protocol:

4.3 Eligible project activities

Eligible project activities are the treatment of eligible manure using one or more of the following MTS types that are installed and operated within the project site:

Table 1: Eligible destruction devices
Type Description
Open flare A device with a pilot flame at the top of a vertical stack that is exposed to atmosphere that combusts a gas.
Enclosed flare A device with an insulated cylinder stack surrounding a burner manifold and combustion/cooling air louvers that combusts a gas.
Boiler A device that combusts a fuel in order to heat a fluid, such as water or leachate, generating vapour that provides thermal energy for various purposes.

If the proponent is not the owner of the project MTS, or any part of the project MTS, the proponent must have an agreement with the owner to ensure:

4.4 Eligible biogas for displacement of fossil fuels

The biogas produced by a project AD MTS and destroyed in an eligible destruction device generating energy may displace fossil fuels.

If a project AD MTS treats other feedstocks in addition to eligible manure, biogas produced by all feedstocks can generate GHG emission reductions from the displacement of fossil fuels under this protocol, if the conditions are met. However, only eligible manure can generate GHG emission reductions from anaerobic storage.

The biogas produced by the project AD MTS and used to displace fossil fuels is eligible to generate GHG emission reductions under this protocol, provided the following conditions are met:

5.0 Additionality

5.1 Legal additionality

GHG emission reductions generated by a project must not occur as a result of federal, provincial, or territorial law (including regulations), municipal by-laws, or any other legally binding mandates. This includes legal requirements to control the release of manure biogas or to treat all or a portion of manure to reduce GHG emissions from the livestock operation or for odour or pollutant control (for example, requirements to use biofilters or chemical treatments).

If at any time after project registration the GHG emission reductions generated by the project become required by law or the result of a legal requirement, the GHG emission reductions will no longer be additional and, therefore, federal offset credits can only be issued for GHG emission reductions generated up to the date immediately preceding the date on which the law or the legal requirement comes into force.

5.2 Provincial or federal pricing mechanisms for GHG emissions

GHG emission reductions from sources that are subject to a federal or provincial pricing mechanism for GHG emissions are not eligible for federal offset credits.

6.0 General requirements

6.1 Project start date

The start date of a project corresponds to the first day eligible manure enters the project MTS to be treated.

6.2 Project site location and geographic boundaries

The proponent must document the location and geographic boundaries of the project site and prepare a site plan. The site plan must show and clearly label:

The geographic boundary of the project site must be established as per the Regulations.

6.3 Environmental and social safeguards

6.3.1 Compliance with applicable environmental legal requirements

The proponent must ensure that the project activities and the project site comply with all applicable laws, including regulations, municipal by-laws, operating permits, and other applicable legal requirements, such as those related to minimizing odour, emergency venting, protecting air and water quality, and managing nutrients from manure.

The proponent must also ensure that any output of the project MTS is disposed of in accordance with all applicable legal requirements, including from relevant federal, provincial, or territorial regulations, and municipal by-laws. Disposal includes, but is not limited to, land application and discharge into water bodies.

6.3.2 Safeguards for land application of acidified liquid treated manure

Acidified liquid treated manure from a chemical MTS will have a lower pH and a higher nitrogen content than untreated manure. To prevent negative impactsFootnote 2 from land application of acidified liquid treated manure, the proponent must ensure that all lands receiving acidified liquid treated manure during a reporting period are covered by a crop nutrient management plan or similar fertilizer management document completed by a Professional Agrologist (P.Ag.) or Certified Crop Advisor (CCA). The plan or document must:

The proponent must ensure that recommendations in the crop nutrient plan or similar fertilizer management document for managing soil acidification risks and nitrogen content are implemented.

7.0 Project GHG boundary

The project GHG boundary (Figure 1) contains the SSRs that must be included or excluded by the proponent in the baseline and project scenarios to determine the GHG emission reductions generated by the project.

Table 2 provides additional details on the SSRs identified for the baseline and project scenarios, as well as justification for their inclusion or exclusion in the quantification of GHG emission reductions. The proponent must assess each of the “included” SSRs that are relevant to the baseline and project scenarios.

Three GHGs are relevant to the SSRs in this protocol: carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). Biogenic CO2 is excluded from the quantification of GHG emission reductions under this protocol, that is, biogenic CO2 from SSR 9, SSR 12, SSR 13, SSR 14, SSR 16 and SSR 17.Footnote 3

Figure 1: Illustration of the project GHG boundary

See long description below
Long description

Figure 1 depicts an illustration of the project GHG boundary. This includes the 18 SSRs relevant to the project type, a dotted line delineating those within the project GHG boundary, and symbols depicting the relationship and connection between SSRs.

SSR 1, SSR 2 and SSR 10 are related to the baseline and project scenarios and are outside the project GHG boundary as the difference between the baseline and project scenarios is assumed to be negligible.

SSR 4 is related to the project scenario only and is outside the project GHG boundary as it is assumed to be negligible.

The remaining SSRs are within the project GHG boundary and are organized in four groupings corresponding to the operation of manure treatment systems, storage of manure, combustion of biogas, and transport of manure, chemicals and treated manure.

SSR 6, SSR 7, SSR 11, SSR 12 and SSR 13 are related to the project scenario only and correspond to the operation of manure treatment systems.

SSR 9 is related to the baseline and project scenarios and corresponds to the storage of manure.

SSR 14, SSR 15, SSR 16 and SSR 17 are related to the project scenario only and correspond to the combustion of biogas.

SSR18 is related to the baseline scenario only and corresponds to the combustion of fossil fuels displaced by biogas.

SSR 3, SSR 5 and SSR 8 correspond to the transport of manure, chemicals and treated manure and are related to project scenario only.

SSR 1 leads SSR 2 which leads to SSR 3 which leads to SSR 6, SSR 7, SSR 9 and SSR 11 individually. SSR 4 leads to SSR 5 which leads to SSR 6. SSR 7 and SSR 11 are interconnected and can lead to either SSR 6 or SSR 8 which both lead to SSR 9 which eventually leads to SSR 10. SSR 11 also leads to SSR 12, SSR 13, SSR 14, SSR 15 and SSR 16 individually. SSR 15 leads to SSR 14 exclusively. SSR 18 is connected exclusively to SSR 17.

8.0 Quantification methodology

This section contains the quantification methodology that the proponent must follow to quantify baseline and project scenario GHG emissions and subsequently, the GHG emission reductions generated by the project.

Baseline scenario GHG emissions are the GHG emissions from the SSRs within the project GHG boundary that would likely have occurred in the absence of the project from the business-as-usual management of the same amount of eligible manure treated in the project scenario. Baseline scenario GHG emissions are quantified based on GHG emissions from the anaerobic storage of eligible manure, and, if applicable, GHG emissions that would have occurred in the absence of the project from the combustion of fossil fuels displaced by eligible biogas, as per Section 8.1.

Project scenario GHG emissions are the GHG emissions from the SSRs within the project GHG boundary that are generated from the eligible project activities, and quantified as per Section 8.2.

The GHG emission reductions generated by the project are quantified by deducting the project scenario GHG emissions from the baseline scenario GHG emissions, as per Section 8.4.

The quantification of both the baseline and project scenario GHG emissions must include all the GHG emissions that were likely to occur in the absence of the project (baseline scenario) and did occur (project scenario) during a reporting period. The proponent must report the sub-totals in tonnes of CO2 equivalent (t CO2e) for each full or partial calendar year of the reporting period to support issuance of the offset credits by calendar year.

For an aggregation of projects, the proponent must quantify GHG emission reductions for each project separately. Subsequently, the GHG emission reductions for each project are to be summed together to determine the GHG emission reductions for the aggregation of projects. The proponent must report the sub-totals of each project within the aggregation in tonnes of CO2 equivalent (t CO2e) for each full or partial calendar year of the reporting period to support issuance of the offset credits by calendar year.

Some emission factors and other reference values used in the quantification methodology are provided in the Emission Factors and Reference Values document.Footnote 4 Raw data must be converted to align with the units presented in the quantification methodology, if necessary.

8.1 Baseline scenario GHG emissions

The proponent must use Equation 1 and the subsequent equations in Section 8.1 to quantify the baseline scenario GHG emissions for each full or partial calendar year covered by the reporting period, based on the included SSRs as set out in Table 2.

The baseline scenario GHG emissions are quantified using a dynamic baseline approach based on eligible manure that is treated in the project scenario.

8.1.1 Baseline scenario CH4 emissions from the anaerobic storage of eligible manure

To quantify baseline scenario CH4 emissions from the anaerobic storage of eligible manure, the proponent must use the equation of one of the following two options:

In all cases, the proponent must derive a site-specific methane conversion factor (MCF), determined as per Section 9.1.5.

Equation 2: Baseline scenario CH4 emissions from anaerobic storage of eligible manure based on VS content for a calendar year covered by the reporting period

8.1.2 Baseline scenario GHG emissions from the combustion of fossil fuels displaced by eligible biogas

If the project includes an AD MTS that produces eligible biogas for displacement of fossil fuels and the proponent chooses to quantify the resulting GHG emission reductions for credit issuance, they must use Equation 4 to quantify baseline scenario GHG emissions from the combustion of fossil fuels displaced by eligible biogas.

Equation 4: Baseline scenario GHG emissions from combustion of fossil fuels displaced by eligible biogas for a calendar year covered by the reporting period

FDE C = i n [ ( FD i , C × EF CO 2 , i ) + ( FD i , C × EF CH 4 , i × GWP CH 4 ) + ( FD i , C × EF N 2 O , i × GWP N 2 O ) ] ÷ 1000

Parameter Description Units
FDEC Baseline scenario GHG emissions from the combustion of fossil fuels displaced by eligible biogas for a calendar year covered by the reporting period (SSR B18) t CO2e
FDi,C Volume of fossil fuel, i, displaced by eligible biogas and used in the baseline scenario for a calendar year covered by the reporting period, as per Equation 5 m3
EFCO2,i CO2 emission factor for fossil fuel, i, as set out in the Emission Factors and Reference Values document kg CO2/m3
EFCH4,i CH4 emission factor for fossil fuel, i, as set out in the Emission Factors and Reference Values document kg CH4/m3
GWPCH4 GWP of CH4, as set out in Schedule 3 to the Act unitless
EFN2O,i N2O emission factor for fossil fuel, i, as set out in the Emission Factors and Reference Values document kg N2O/m3

1000 Conversion factor, kilograms to tonnes kg/t
n Number of fossil fuels displaced by eligible biogas unitless
i Fossil fuel displaced by eligible biogas unitless
C Calendar year unitless

The volume of fossil fuels that would have been used in the baseline scenario to generate the equivalent amount of energy as the combustion of eligible biogas must be calculated using Equation 5. However, if the value of FDi,C , obtained from Equation 5, is higher than the highest annual volume of fossil fuels used during the 3 years before the project start date, the proponent must use this highest annual volume as the value of FDi,C in Equation 4.

Equation 5: Volume of fossil fuel displaced by eligible biogas for a calendar year covered by a reporting period

FD i , C = BGD C × ( HHV BG HHV FF , i )

Parameter Description Units
FDi,C Volume of fossil fuel, i, displaced by eligible biogas and used in the baseline scenario for a calendar year covered by the reporting period m3
BGDC Volume of biogas eligible for displacement of fossil fuels in the project scenario for a calendar year covered by the reporting period, as per Sections 9.1.6 and 9.3 m3
HHVBG Higher heating value of biogas produced by the project AD MTS, as set out in the Emission Factors and Reference Values document MJ/m3
HHVFF,i Higher heating value of fossil fuel, i, displaced by eligible biogas, as set out in the Emission Factors and Reference Values document MJ/m3
i Fossil fuel displaced by eligible biogas unitless
C Calendar year unitless

If eligible biogas has been upgraded to the standards required to be RNG, the proponent must use the applicable higher heating value for RNG, as set out in the Emission Factors and Reference Values document, for the parameter HHVBG in Equation 5.

If eligible biogas has not been upgraded to the standards required to be RNG, the proponent must use the higher heating value for biogas regardless of the CH4 composition of the biogas, as set out in the Emission Factors and Reference Values document, for the parameter HHVBG in Equation 5.

Despite the previous provision, the proponent may determine a project-specific higher heating value for eligible biogas by measuring the energy density of the biogas following the requirements for fuel heat content monitoring set out in Section 2.D.3 of the latest available version of Canada’s Greenhouse Gas Quantification Requirements / Greenhouse Gas Reporting Program, and corrected to standard conditions.

8.2.1 Project scenario GHG emissions from fossil fuels combustion and energy usage

The proponent must use Equation 7 to quantify the GHG emissions from the combustion of fossil fuels used for the transport of eligible manure, chemicals, and treated manure as well as from the operation of the project MTS for a calendar year covered by the reporting period. For the GHG emissions from transport, the volume of fossil fuels consumed (FFi,C) is determined using the total transport distance and vehicle energy consumption data.

The proponent must use Equation 8 to quantify the GHG emissions from the use of grid electricity for the operation of the project MTS for a calendar year covered by the reporting period.

If both fossil fuels and grid electricity are used for the operation of the project MTS, the proponent must use the summation of Equation 7 and Equation 8 as the total GHG emissions for SSR P6, SSR P7 and SSRP11 for reporting purposes, as per Section 11.0.

The amount of CH4 destroyed in each eligible destruction device is dependent on the CH4 destruction efficiency for each device (DECH4). The Emission Factors and Reference Values document sets out default CH4 destruction efficiencies that the proponent must use for each eligible destruction device in the project.

Despite the previous provision, the proponent may determine a device-specific destruction efficiency for each eligible destruction device in the project. Testing for the device-specific destruction efficiency must be conducted each reporting period, and include at least 3 test runs, with the accepted final value being one standard deviation below the mean of the measured efficiencies.

8.3 Leakage

A project in which the quantity of manure produced in the project scenario is reduced compared to the baseline scenario (for example, due to a reduction in livestock number) would pose a leakage risk if GHG emission reductions were quantified based on historical manure quantities. This form of leakage is avoided in this protocol by quantifying GHG emissions in the baseline scenario based on the quantity of manure that is treated in the project scenario (that is, using a dynamic baseline approach) to ensure functional equivalency between the baseline and project scenarios.

As a result, there is no leakage discount factor (which corresponds to variable Ci in the formula in subsection 20(2) of the Regulations) to be applied for the quantification of GHG emission reductions generated by a project implemented following this protocol.

8.4 Project GHG emission reductions

The proponent must use Equation 25 to quantify the GHG emission reductions (ERC) generated by the project, which correspond to the GHG reductions determined in accordance with section 20 of the Regulations.

9.0 Measurement and data

9.1   Data collection

If the proponent quantifies baseline scenario CH4 emissions from the anaerobic storage of eligible manure based on its VS content (Option 1 with Equation 2 as per Section 8.1.1), they must measure:

If the proponent quantifies baseline scenario CH4 emissions from the anaerobic storage of eligible manure based on the number of livestock (Option 2 with Equation 3 as per Section 8.1.1), they must determine:

Regardless of the option chosen to quantify baseline scenario CH4 emissions from the anaerobic storage of eligible manure, the proponent must:

9.1.1 Mass of eligible manure and treated manure

The proponent must measure the quantity of eligible manure and treated manure by volume or wet weight.

If eligible manure or treated manure is measured by volume, the volume must be converted to mass. A density of 1 tonne/m3 must be used for eligible manure and for liquid treated manure. The density of the solid treated manure from a mechanical MTS must be measured every 3 months and the average density must be used to convert volume to mass.

9.1.2 VS content

The proponent must determine the VS content monthly as follows:

In addition to the two VS content measures above, if the proponent uses Equation 22 to quantify project scenario GHG emissions from the storage of solid treated manure stored in static piles or composted, and if the project activity consists of an AD MTS followed by a mechanical MTS, the proponent must determine the VS content of the treated manure from the AD MTS and prior to entering the mechanical MTS and use it in Equation 24. The VS content of manure must be determined as follows:

9.1.3 Number of livestock and days of eligible manure production

The proponent must count the number of days eligible manure was produced and the number of livestock each day to support parameters LHCl,C and Dl,C.

For Dl,C the proponent must count the number of days in a calendar year that eligible manure treated by the project MTS was produced for each livestock type, l. Livestock types and their descriptions are set out in the Emission Factors and Reference Values document.

LHCl,C represents an average number of livestock for each livestock type, l, producing eligible manure treated by the project MTS. The proponent must, therefore, count the number of livestock for each livestock type, l, producing eligible manure treated by the project MTS each day eligible manure is produced by the livestock in a calendar year. The daily count must be averaged over the number of days eligible manure was produced by livestock type, l (Dl,C).

9.1.4 Project-specific MTS efficiency rate

The proponent must determine a project-specific MTS efficiency rate by determining the VS content of samples taken before and after treatment by the project MTS, as follows:

Equation 26: Efficiency rate for the project MTS

Eff MTS , i = ( VS before MTS , i VS after MTS , i ) VS before MTS , i

Parameter Description Units
EffMTS,i Project-specific MTS efficiency rate for sampling, i unitless
VSbeforeMTS,i VS in eligible manure before treatment by the project MTS, at sampling, i, as per Section 9.3 kg/t manure
VSafterMTS,i VS in liquid treated manure after treatment by the project MTS, at sampling, i, as per Section 9.3 kg/t manure
i Sampling (n ≥ 3) unitless

9.1.5 Methane conversion factor (MCF)

The proponent must determine a single site-specific MCF to be used in both the baseline and project scenarios. The site-specific MCF must be determined each calendar year covered by the reporting period following the method in Annex 10A.3 of the IPCC 2019 guidelinesFootnote 9 and the following requirements for determining input values:

A single MCF must be determined for the whole project site in the following situations:

In all other cases, the proponent must determine multiple MCF values as follows: 

If the proponent must determine multiple MCF values, a single average site-specific MCF must be determined for each calendar year covered by the reporting period. For a single livestock operation with multiple under-barn storages, a simple average of the MCF for each under-barn storage structure must be used for the livestock operation. For a project site that includes multiple livestock operations, a weighted average must be used based on the quantity of manure treated as per Equation 27.

Equation 27: Site-specific MCF for a project site including multiple livestock operation for a calendar year covered by the reporting period to be used in both the baseline and project scenarios

MCF C = u n [ MCF u × QM u , C QM Total ]

n Number of different removal frequencies or under-barn storages requiring a unique MCF for a calendar year covered by the reporting period. unitless
u Removal frequency or under-barn storage requiring a unique MCF unitless
C Calendar year unitless

9.1.6 Volume of biogas eligible for displacement of fossil fuels

If the proponent quantifies GHG emissions from the combustion of fossil fuels displaced by eligible biogas using Equation 4, they must measure the volume of eligible biogas using measuring devices as per Section 9.2.4.2.

9.1.7 Leak surveys

To use a leak rate (LR) of 0.005 in Equation 10, the proponent must conduct leak surveys according to the following requirements:

When carrying out the leak surveys, a leak is defined as one of the following:

If the requirements above for using a leak rate of 0.005 are not met, the proponent must use a leak rate of 0.05 in Equation 10.

9.1.8 Emergency venting

The proponent must estimate the volume of biogas accumulated in the digester or in a secondary storage structure (that is, biogas bladder) that was vented to the atmosphere during an emergency venting event. If direct measurement is not possible, the volume of stored biogas may be determined by an engineering estimate.

9.2 Measuring devices

All measuring devices listed in this section must be operated according to the manufacturer's specifications.

9.2.1 General measuring devices

If the proponent quantifies baseline scenario CH4 emissions from the anaerobic storage of eligible manure based on the VS content (Option 1 with Equation 2 as per Section 8.1.1), they must use a measuring device to measure the quantity of eligible manure treated by the project MTS by weight or volume, such as with a flow meter, a truck scale or a volumetric sensor.

The quantity of grid electricity used for the operation of the project MTS must be measured by permanent meters or determined using purchase records.

For projects including one or more under-barn storage structure(s), temperature must be measured daily at mid-depth of the treated manure in the under-barn storage structure(s) and averaged to obtain a monthly average temperature.

9.2.2 Measuring devices specific to a project chemical MTS

If the project includes a project chemical MTS, the proponent must use a portable pH meter that directly measures pH in the treated manure storage at least daily.

9.2.3 Measuring devices specific to a project mechanical MTS

If the project includes a project mechanical MTS and if the proponent quantifies baseline scenario CH4 emissions from the anaerobic storage of eligible manure based on the VS content (Option 1 with Equation 2 as per Section 8.1.1), the proponent must use the following measuring devices:

9.2.4 Measuring devices specific to a project AD MTS

9.2.4.1 Treated manure measuring devices

If the project includes a project AD MTS and if the proponent quantifies baseline scenario CH4 emissions from the anaerobic storage of eligible manure based on the VS content (Option 1 with Equation 2 as per Section 8.1.1), the proponent must use a flow meter or a scale to measure treated manure by volume or weight at the frequency set out in Table 3.

9.2.4.2 Biogas flow meters

For any project AD MTS, the proponent must use a permanent flow meter that directly and separately measures the volume of biogas produced by the project MTS and delivered to each individual eligible destruction device at the frequency set out in Table 3.

9.2.4.3 Biogas temperature and pressure gauges

If the flow meter of a project AD MTS automatically corrects the biogas volume to the reference temperature and pressure conditions set out in Equation 12, no additional temperature and pressure gauges are required.

If the flow meter does not automatically correct the biogas volume, the proponent must use permanent temperature and pressure gauges to measure temperature and pressure at the same measurement frequency as the uncorrected volume of biogas (Section 9.3). Biogas temperature and pressure must be measured under the same conditions (wet or dry basis) as the biogas volume.

The biogas volume data must be corrected from measured temperature and pressure conditions to the reference temperature and pressure conditions using Equation 12.

9.2.4.4 Methane analyzers

For any project AD MTS, the proponent must use a permanent or portable methane analyzer (for example, gas chromatographs) that directly measures the CH4 content in the biogas on a volumetric basis at the frequency set out in Table 3.

9.2.4.5 Arrangement of biogas measuring devices

Flow meters and methane analyzers must be arranged in such a way as to ensure the data is representative of the biogas produced and combusted in the project.

For a project with multiple eligible destruction devices:

Additionally, flow meters and methane analyzers must be placed to:

Measuring devices must be arranged such that biogas CH4 content is measured under the same conditions (wet or dry basis) as biogas volume, temperature, and pressure. However, a moisture-removing component may separate a methane analyzer and a flow meter where the methane analyzer is placed upstream of the moisture-removing component (CH4 content measured on a wet basis), and the flow meter is placed downstream of the moisture-removing component (biogas volume measured on a dry basis). A moisture-removing component must not separate a methane analyzer and flow meter in any other configuration other than previously described. Other devices or equipment that could change the biogas composition by volume must not separate a methane analyzer and a flow meter.

9.2.4.6 Leak detection

To conduct leak surveys as per Section 9.1.7, the proponent must use a measuring device for leak detection that:

9.3 Measurement method and frequency

9.4 Quality assurance and quality control

The proponent must have documented quality assurance and quality control (QA/QC) procedures and must implement them to ensure that all measurements and calculations are made in accordance with this protocol and can be verified.

All measuring devices listed in Section 9.2, except for grid electricity meters and leak detection measuring devices operated by a third party certified for that purpose, must be checked for accuracy by following manufacturer specifications at least once each calendar year, with the last occurring no more than 2 months before or after the end of the reporting period.

The measurement accuracy of all these measuring devices must be within a ± 5% accuracy range. When the measurement accuracy of a measuring device exceeds the ± 5% range, the appropriate corrective actions must be taken on the device, in accordance with the manufacturer specifications.

After the corrective actions, the measuring device must be rechecked for accuracy. If the measurement accuracy of the measuring device is still not within the ± 5% range, the measuring device must be calibrated by the manufacturer or by a third party certified for that purpose and following manufacturer specifications, no more than 2 months after the accuracy check conducted following the corrective actions. If the measuring device was manufactured with no possibility of calibration, it must be replaced no more than 2 months after the accuracy check conducted following the corrective actions.

When the measurement accuracy of a measuring device, except for a leak detection measuring device, indicates a reading outside of a ± 5% accuracy range, the following conditions must be followed for the entire period from the last time the measuring device showed a reading within ± 5% accuracy until the measuring device shows a return to ± 5% accuracy:

When the measurement accuracy of a leak detection measuring device indicates a reading outside of a ± 5% accuracy range, any leak survey conducted during the period from the last time the leak detection device showed a reading within ± 5% accuracy until the device shows a return to ± 5% accuracy, is considered as not meeting the requirements as per Section 9.1.7.

All measuring devices listed in Section 9.2, except for grid electricity meters, leak detection measuring devices operated by a third party certified for that purpose and portable pH meters, must be calibrated by the manufacturer or by a third party certified for that purpose and following manufacturer specifications, in accordance with the manufacturer specified frequency or every 5 years, whichever is more frequent. However, if the device is factory calibrated and the manufacturer specifies that no recalibration is required, the factory calibration then needs to be validated on-site by either the manufacturer or a certified third party in accordance with the manufacturer specified frequency or every 5 years, whichever is more frequent. 

For portable pH meters, the user must perform a calibration daily or in accordance with the manufacturer specified frequency, whichever is more frequent.

9.5 Missing data

If a measuring device fails to produce data as required in Sections 9.1, 9.2 and 9.3, missing data may be substituted following the requirements in this section. If missing data cannot be substituted as per the applicable requirements, no GHG emission reductions can be quantified for the issuance of offset credits for the period during which data is missing.

In the event that periods of missing data occur more than once during a reporting period, data may be substituted to quantify:

9.5.1 Missing data from a biogas measuring device

The proponent may substitute missing data from a biogas measuring device (that is, flow meter or methane analyzer) only if the operational status of the eligible destruction devices can be demonstrated in accordance with the requirements in Section 9.6.3.1 during the period of missing data. In addition, missing data from a flow meter or methane analyzer may only be substituted in accordance with the following conditions:

For a project with biogas volume or CH4 content data missing for a period of up to 7 consecutive days, the proponent must use the appropriate substitution method set out in Table 4 to substitute the data.

For data missing for more than 7 consecutive days, only the data for the period of up to 7 days may be substituted. No data may be substituted for the period after the 7th consecutive day, and no GHG emission reductions may be quantified for the issuance of offset credits for that period.

Table 4: Missing data substitution methods for biogas measuring devices
Missing data period Substitution method
Less than 6 consecutive hours Use the average of the 4 hours immediately prior to and after the missing data period.
6 to less than 24 consecutive hours Use the 95% upper or lower confidence limit of the 72 hours prior to or after the missing data period, whichever results in greater conservativeness.
1 to 7 consecutive days Use the 90% upper or lower confidence limit of the 72 hours prior to or after the missing data period, whichever results in greater conservativeness.

9.5.2 Missing data from VS content

The proponent may substitute missing data from monthly VS content sampling in eligible manure or treated manure, as per Section 9.1.2, only if the following two conditions are met:

If the conditions for substitution listed above are met, the proponent may use the appropriate VS content value (that is, eligible manure or treated manure) from the month prior to the month of the missing VS content data to use in Equation 2 (VSSource,i,m) if missing data from eligible manure VS content, or in Equation 18 and Equation 24 (VSLTM,m) if missing data from treated manure VS content.

If the conditions for substitution listed above are not met, no GHG emission reductions from anaerobic storage (SSR 9) can be quantified for the issuance of offset credits for the period during which data is missing. The proponent must set the value of VSSource,i,m in Equation 2 and the value of VSLTM,m in Equation 18 and Equation 24 to zero. GHG emissions from all other SSRs must continue to be quantified as per Section 8.0.

The proponent may not substitute missing data from VS content sampling required for defining a project-specific MTS efficiency rate, as per Section 9.1.4.

9.5.3 Missing data from pH measurement for a project chemical MTS

For a project including a chemical MTS with pH data missing for a period of up to 7 consecutive days, the proponent must use the 90% upper or lower confidence limit of the 72 hours prior to or after the missing data period, whichever results in greater conservativeness.

After the 7th consecutive day of missing pH data, the project chemical MTS is considered not operational as per Section 9.6.1, and no missing data may be substituted for that period.

9.6 Operational status of a project MTS

9.6.1 Operational status of a project chemical MTS

The proponent must monitor and record pH according to Section 9.2.2.

A project chemical MTS is considered operational if the daily average pH is:

If a project chemical MTS is considered not operational for 1 month or more in the period of May to October, the project chemical MTS is considered operational again once the two following conditions are met:

In all other cases (that is, not operational for less than 1 month in the period of May to October, or not operational for any amount of time from November to April), the project chemical MTS is considered operational again once the two following conditions are met:

If during any period of time a project chemical MTS is considered not operational, the system is not functioning properly or is not operated in accordance with the manufacturer specifications, or its operational status cannot be confirmed, no GHG emission reductions can be quantified for the issuance of offset credits for this period.

9.6.2 Operational status of a project mechanical MTS

For a project mechanical MTS, the proponent must monitor and record an indicator of operational status appropriate for the system using a monitoring instrument in accordance with the manufacturer specifications, such as manure input, motor speed, system pressure, or temperature.

If during any period of time a project mechanical MTS or the monitoring instrument is not functioning properly or not operated in accordance with the manufacturer specifications, or the operational status cannot be confirmed, no GHG emission reductions can be quantified for the issuance of offset credits for this period.

9.6.3 Operational status of a project AD MTS

For a project AD MTS, the proponent must monitor and record an indicator of operational status appropriate for the system in accordance with the manufacturer specifications, such as biogas production, digester temperature, or pH.

If during any period of time a project AD MTS, including an eligible destruction device, or the monitoring instrument is not functioning properly or not operated in accordance with the manufacturer specifications, or the operational status cannot be confirmed, no GHG emission reductions can be quantified for the issuance of offset credits for this period.

9.6.3.1 Operational status of eligible destruction devices

For a project AD MTS, the proponent must monitor and record the operational status of all eligible destruction devices by using, for each destruction device, a monitoring instrument that records the operational status at least once per hour.

For a flare (open or enclosed), the operational status must be determined based on data from a thermocouple. For the flare to be considered operational, the thermocouple must indicate that the flare temperature meets or exceeds 260˚  C (the minimum temperature for CH4 destruction).

For all other eligible destruction devices listed in Table 1, the destruction device monitoring instrument must monitor and record an indicator of operational status appropriate for the destruction device such as energy output.

Requirements for the operational status of eligible destruction devices apply to all eligible destruction devices located within the project site, including those located at an adjacent destruction facility.

In cases where biogas is combusted in an eligible destruction device located at an adjacent destruction facility, the proponent must obtain the monitoring data demonstrating the operational status of the eligible destruction device; otherwise, no GHG emission reductions generated with this device can be quantified for the issuance of offset credits.
