61  Requirement to undertake waste audits

 (1) The project proponent may choose to undertake waste audits for the purpose of monitoring one or more of the project’s source separation activities or sub‑activities.

Note: If the project proponent chooses to use waste audits to monitor parameter WEO,w for a source separation activity, or parameter WEO,w,sa for a sub‑activity included in an aggregated waste diversion activity, the project proponent must monitor the parameter using waste audits for the whole of the project (see subsection 60(4)).

 (2) The waste audits for an activity or sub‑activity must meet the following requirements:

 (a) the first waste audit for the activity or sub‑activity must be undertaken during the first reporting period for the project;

 (b) such number of subsequent waste audits as is required by subsection (3) for the activity or sub‑activity must be undertaken in later reporting periods for the project;

 (c) only one waste audit may be undertaken in any 12‑month period;

 (d) each waste audit must consist of at least 2 audit periods that occur at times representative of relevant seasonal variation;

 (e) each audit period must run for at least 1 week;

 (f) during each audit period, at least one sample per day must be taken from a randomly selected truck or other bulk container used by the activity or sub‑activity to divert eligible organic material from landfill;

 (g) the number of samples taken during each waste audit must be sufficient to obtain statistical confidence of 95% (plus or minus 5%) for each waste mix type present in the eligible organic material diverted from landfill by the activity or sub‑activity;

 (h) the samples taken must comprise aggregated collected waste from whole loads prior to processing;

 (i) the aggregated collected waste must be sorted into eligible organic material, other organic waste and inert waste;

 (j) all measurements of quantity must be in tonnes.

Note: The project proponent must keep a record of evidence that each waste audit undertaken consists of at least 2 audit periods that occur at times representative of relevant seasonal variation (see section 57).

 (3) For the purposes of paragraph (2)(b), the number of subsequent waste audits required for the activity or sub‑activity is as follows:

 (a) if the average annual abatement resulting from all of the project’s source separation activities is less than 50 000 tonnes CO2‑e—2;

 (b) if the average annual abatement resulting from all of the project’s source separation activities is 50 000 tonnes CO2‑e or more and less than 150 000 tonnes CO2‑e—3;

 (c) if the average annual abatement resulting from all of the project’s source separation activities is 150 000 tonnes CO2‑e or more—5.
