Division 5.4.3—Method 2—methane released from wastewater handling (industrial)

5.43  Method 2—methane released from wastewater handling (industrial)
 (1) For paragraph 5.41(1)(b) and subject to this section, method 2 for wastewater handling (industrial) is the same as method 1 under section 5.42.
 (2) In applying method 1 under section 5.42, each mention of CODw,i in subsection 5.42(5) must be estimated from wastewater entering the plant and must be calculated by using:
 (a) facility operating data that measures the volumetric influent rate and the influent rate of COD concentrations; or
 (b) if data is available on the biochemical oxygen demand (BOD) in the wastewater—that data converted to COD in accordance with the following formula:

 (2A) In applying method 1 under section 5.42, the reference to 0.75 in subsections 5.42(2) and (3) is to read as a reference to 1.00.
 (3) Wastewater used for the purposes of subsection (2), must be sampled and analysed for COD in accordance with the requirements in sections 5.44, 5.45 and 5.46.

5.44  General requirements for sampling under method 2
 (1) A sample must be representative of the wastewater and the COD concentrations at the plant.
 (2) The samples must be collected on enough occasions to produce a representative sample.
 (3) The samples must also be free of bias so that any estimates are neither over nor under estimates of the true value.
 (4) Bias must be tested in accordance with an appropriate standard (if any).
 (5) The value obtained from the sample must only be used for the plant for which it was intended to be representative.

5.45  Standards for analysis
 (1) Samples of wastewater must be analysed for COD in accordance with:
 (a) ISO 6060:1989; or
 (b) sections 5220B, 5220C or 5220D of APHA (1995); or
 (c) an equivalent Australian or international standard.
 (2) Samples of wastewater must be analysed for BOD in accordance with:
 (a) AS 4351.5—1996; or
 (b) section 5210B of APHA (1995); or
 (c) an equivalent Australian or international standard.

5.46  Frequency of sampling and analysis
  Wastewater must be sampled and analysed on at least a monthly basis.

Division 5.4.4—Method 3—methane released from wastewater handling (industrial)

5.47  Method 3—methane released from wastewater handling (industrial)
 (1) For paragraph 5.41(1)(c) and subject to subsection (2), method 3 is the same as method 2 under section 5.43.
 (2) In applying method 2 under section 5.43, the wastewater must be sampled in accordance with AS/NZS 5667.10:1998 or an equivalent Australian or international standard.

Division 5.4.5—Wastewater handling (industrial)—Flaring of methane in sludge biogas

5.48  Method 1—flaring of methane in sludge biogas
 (1) For paragraph 5.41(2)(a),
