Part 4 The net abatement amount

Division 4.1 The net abatement amount

4.1 The net abatement amount

Note See paragraph 106(1)(c) of the Act.

For a project to which this Determination applies, the carbon dioxide equivalent net abatement amount for the project in relation to a reporting period for the project is taken to be the quantity of methane emissions avoided as a consequence of the project, minus emissions from electricity and fuel used to operate the gas capture and combustion equipment, as calculated in accordance with Subdivision 4.2.3.

Division 4.2 Calculations

Subdivision 4.2.1 Preliminary

4.2 How calculations are to be made

In this Part:

(a) all calculations:

(i) are in respect of activities undertaken, or outcomes achieved, during the reporting period for the eligible offsets project;
(ii) must be performed at least once every 12 months;

(b) for all relevant equations:

(i) n = number of combustion devices;
(ii) h denotes a combustion device;

(c) unless otherwise specified, a reference to a project is a reference to an eligible offsets project that meets the requirements of Part 2;

(d) if a calculation in this Division refers to a factor or parameter prescribed in the NGER Measurement Determination or the NGER Regulations, the person carrying out the calculations must apply, to the entire offsets reporting period, the NGER Measurement Determination or NGER Regulations in force at the end of the reporting period; and

(e) the use of the PigBal model in the calculations under this Part must be in accordance with any guidelines relating to the use of that model for the purposes of this Determination published from time to time on the Department’s website.

4.3 Calculating the baseline for the project

(1) The baseline for a project is the methane that would have been generated and released from each lagoon included in the project, for each year of the project, in the absence of the abatement activity.

(2) The project baseline must be calculated based on the amount of volatile solids (VS) in the effluent stream deposited into each lagoon included in the project.

(3) The amount of VS in the effluent stream must be calculated using the PigBal model.

(4) Project proponents must input all required data into the PigBal model to calculate VS in accordance with the procedures and requirements set out in the PigBal Manual.

Subdivision 4.2.2 Baseline emissions (Eb)

4.4 Calculating the baseline methane emissions

Baseline methane emissions must be calculated using the following formula:

	Equation 1.1

Where:

Eb = methane emissions from the operation of uncovered anaerobic treatment lagoons within the project site in the absence of the project, in tonnes of CO2‑e.

View image in the official source = the factor 6.784 x 10-4 x View image in the official source, which converts cubic metres of methane to tonnes of CO2-e at standard conditions.

Qb = volume of methane that would be released from the operation of uncovered anaerobic treatment lagoons within the project site in the absence of the project, in cubic metres of methane (m3 CH4) at standard conditions, calculated using Equation 1.2.

4.5 Calculating the volume of methane

The volume of methane that would be emitted from the operation of uncovered anaerobic treatment lagoons within the project site in the absence of the project must be calculated using the following formula:

	Equation 1.2

Where:

View image in the official source = volume of methane that would be released from the operation of uncovered anaerobic treatment lagoons within the project site, in the absence of the project, in cubic metres of methane (m3 CH4) at standard conditions.

VS = quantity of Volatile Solids entering the project lagoons, in kilograms, calculated using the PigBal model in accordance with the PigBal Manual.

Bo = 0.45, which is the maximum methane-producing capacity from VS for pigs, in units of cubic metres of methane per kilogram of VS (m3 CH4/kg VS).

MCF = methane conversion factor which reflects that portion of Bo that is achieved under temperature and treatment specifications. For anaerobic lagoons across Australia this is 0.9.

Subdivision 4.2.3 Calculating the carbon dioxide equivalent net abatement amount

4.6 Calculating net greenhouse gas abatement (A)

The carbon dioxide equivalent net abatement amount must be calculated using the following formula:

	Equation 2.1

Where:

A = net greenhouse gas abatement due to the project, in tonnes of CO2‑e.

View image in the official source = quantity of emissions avoided as a consequence of the project in tonnes of CO2‑e, as calculated in Equation 2.2 or Equation 3.1 as applicable.

View image in the official source= emissions from fuel and/or grid derived electricity used to operate gas capture and combustion equipment for the purpose of the project, measured in tonnes of CO2‑e as calculated in accordance with Equation 4.1.

Subdivision 4.2.4 Calculating Ap

4.7 Calculating avoided greenhouse gas emissions (Ap)

(1) Subject to subsection (2), avoided greenhouse gas emissions must be calculated using the following formula:

	Equation 2.2

Where:

View image in the official source = quantity of emissions avoided as a consequence of the project, in tonnes of CO2‑e.

View image in the official source = the factor 6.784 x 10-4 x View image in the official source, which converts cubic metres of methane to tonnes of CO2-e at standard conditions.

View image in the official source = volume of methane destroyed by combustion device h, in cubic metres (m3) and capped according to section 4.11.

View image in the official source = quantity of nitrous oxide emissions released as a result of methane destruction from all combustion devices, in tonnes of CO2‑e.

(2) If the requirements set out in subsection 4.13(1) are met, a project proponent may calculate Ap by substituting Equation 3.1 for Equation 2.2.

Subdivision 4.2.5 Calculating Qcom,h

4.8 Calculating volume of methane destroyed by combustion device (Qcom,h)

The volume of methane destroyed by a combustion device is to be calculated using the following formula:

Qcom,h	Equation 2.3

Where:

Qcom,h = capped volume of methane destroyed by combustion device h, in cubic metres (m3) and capped according to section 4.11.

View image in the official source = volume of methane sent to combustion device h, in cubic metres (m3) as calculated in Equation 2.4.

View image in the official source = methane destruction efficiency for device h, as a fraction, as determined in accordance with sections 3.2 and 4.9.

4.9 Determining the destruction efficiency of combustion device (DEh)

(1) For an open flare, a default value of 0.98 must be used for the destruction efficiency of the device.

(2) Subject to subsection (4), the destruction efficiency of enclosed flares or internal combustion engines may be either:

(a) a default value of 0.98; or

(b) measured in accordance with Division 4.3.

(3) Subject to subsection (4), the destruction efficiency of a gas boiler system has a default value of 0.98.

(4) A default destruction efficiency of 0.98 may be used only if the combustion device is installed and operated in accordance with the requirements set out by the manufacturer.

Subdivision 4.2.6 Calculating QCH4,h

4.10 Calculating the volume of methane

(1) The volume of methane is to be calculated using the following formula:

	Equation 2.4

Where:

View image in the official source = volume of methane sent to combustion device h, in cubic metres (m3).

View image in the official source= volume of biogas sent to combustion device h, adjusted toView image in the official sourcestandard conditions, in cubic metres (m3).

View image in the official source = the proportion of the volume of biogas that is methane.

(2) To calculate View image in the official source either:

(a) a default value of 0.70 may be used (70% of the biogas released from uncovered lagoons as defined in the NGER Measurement Determination); or

(b) the proportion of the volume of biogas that is methane may be measured in accordance with Division 4.3.

(3) Where volumetric measurements have not been adjusted to standard conditions based on actual temperature and pressure readings of the biogas, Qbiogas,h must be multiplied by 0.97 before multiplying by View image in the official source.

(4) If:

(a) more than one combustion device is installed; and

(b) the devices have the same destruction efficiency as determined in accordance with section 4.9;

then for the purposes of calculating QCH4,h the devices may be considered as one device.

Note A single flow meter may be used to measure Qbiogas,h for all combustion devices that have the same destruction efficiency.

(5) Subject to subsection (6), in the event of a failure of one or more of the combustion devices referred to in paragraph (4)(a), a project proponent must:

(a) document the type of device and the date and duration of the failure;

(b) adjust the value of QCH4,h to account for methane not combusted; and

Note An example of how the adjustment referred to in paragraph (5)(b) may be demonstrated is by using deductions based on estimations of methane combusted from electricity generated.

(6) If the requirements of subsection (5) cannot be met for one or more devices, then the destruction efficiency of that device or those devices will be zero for the duration of the failure referred to in subsection (5).

4.11 Capping the volume of methane

(1) Qb (calculated using Equation 1.2) and View image in the official source (calculated using Equation 2.4) must be estimated over the same time period and at least once every 12 months.

(2) If the value of the volume of methane destroyed by all combustion devices (View image in the official source) is greater than the value for baseline methane emissions (Qb), the value for Qb must be used instead of the value forView image in the official source in Equation 2.2.

Subdivision 4.2.7 Calculating EN2O

4.12 Calculating nitrous oxide emissions

(1) Subject to subsection (2), nitrous oxide emissions released as a result of methane destruction must be calculated using the following formula:
