more than 2 metres; and
           (b) in which the biological treatment of biomass or other organic matter occurs through anaerobic digestion; and
           (c) from which the resulting methane emissions are not captured and are instead vented into the atmosphere.

       digestate means the residual solids or semisolids stream that:
           (a) remains in an anaerobic digester following anaerobic treatment; and
           (b) must be removed periodically.

       displacement abatement, in relation to a project, means the carbon dioxide equivalent net abatement amount for a reporting period (worked out in accordance with Division 3 of Part 4), attributable to biomethane production.

       domestic or commercial wastewater has the meaning given by subsection 5.23(2) of the NGER (Measurement) Determination.

       effluent, in relation to a deep open anaerobic lagoon, means the liquid outflow from the lagoon.

       eligible biogas waste means biogas waste that is:
           (a) domestic or commercial wastewater, or industrial wastewater; or
           (b) mixed solid waste within the meaning of the Carbon Credits (Carbon Farming Initiative—Alternative Waste Treatment) Methodology Determination 2015; or
           (c) eligible organic material within the meaning of the Carbon Credits (Carbon Farming Initiative—Source Separated Organic Waste) Methodology Determination 2016; or
           (d) eligible animal effluent biogas waste within the meaning of the Carbon Credits (Carbon Farming Initiative—Animal Effluent Management) Methodology Determination 2019.

              Note:       The proportion of eligible waste used to generate biogas to be treated by carrying out biomethane production within the project must be able to be determined.

       eligible wastewater, in relation to a wastewater project, means:
           (a) domestic or commercial wastewater; or
           (b) industrial wastewater;
       from an historical source for the project.

       emissions destruction has the meaning given by subsection 8A(4).

       engineered biodigester means a purpose-built closed vessel that:
           (a) is for the biological treatment of organic matter through anaerobic digestion; and
           (b) has heating and stirring features; and
           (c) is not a covered lagoon.

            Note: Examples of engineered biodigesters include the following:
            (a) plug flow reactors;
            (b) continuously stirred tank reactors;
            (c) fixed film digesters;
            (d) up flow anaerobic sludge blanket digesters.

       forerunner project:
           (a) in relation to a restarting biomethane conversion and displacement project—has the meaning given by paragraph 8E(a); or
           (b) in relation to a restarting biomethane displacement-only project—has the meaning given by paragraph 8F(a).

       historical period of sampling means, for each deep open anaerobic lagoon that is replaced as part of a wastewater project, the period during which sampling was undertaken from the operation of that lagoon for the purposes of working out baseline emissions for the project using Subdivision 4 of Division 3 of Part 4, which:
           (a) was 1 year or 10 consecutive days; and
           (b) started no earlier than 18 months before the day on which a section 22 application is made in relation to the
