8     Other—leaker                              5.88 × 10‑3                         1.46 × 10‑5   tonnes CO2‑e / component ‑ hour

 (5) For subsection (4) the LDAR program must survey each component used in natural gas gathering and boosting at the facility at least once in a reporting year in accordance with:
         (a)  paragraph 98.234(a)(1) of Title 40, Part 98 of the Code of Federal Regulations, United States of America using optical gas imaging with a sensitivity of 60 grams per hour; or
         (b) the method outlined in USEPA Method 21—Determination of organic volatile compound leaks, as set out in Appendix A‑7 of Title 40, Part 60 of the Code of Federal Regulations, United States of America where a leaker is detected if 10,000 parts per million or greater is measured consistent with that method; or
         (c) an equivalent leak detection standard.
 (6) To determine whether a component is a leaker or non leaker at a period of time:
         (a)  if a leak is detected in a survey the component is assumed to leak from the later of the beginning of the reporting year or last survey where it was a non leaker; and
         (b)  after a leak is detected in a survey the component is assumed to leak until the earlier of the end of the reporting year or the next survey where it is a non leaker.

Division 3.3.6D—Produced water from oil and gas exploration and development, crude oil production, natural gas production or natural gas gathering and boosting (other than emissions that are vented or flared)

3.73N  Available methods
 (1) Subject to section 1.18, one of the following methods must be used for estimating fugitive emissions of methane (other than emissions that are vented or flared) released during a year from produced water relating to the operation of a facility that is constituted by a relevant activity:
 (a) method 1 under section 3.73NA;
 (b) method 2 under section 3.73NB.
Note: There is no method 3 or 4 for this Division.
 (2) However, for incidental emissions another method may be used that is consistent with the principles in section 1.13.
 (3) In this Division, a relevant activity is oil or gas exploration and development, crude oil production, natural gas gathering and boosting and onshore or offshore natural gas production.

3.73NA  Method 1—produced water (other than emissions that are vented or flared)
  Method 1 is:

  Eij  = Wi ×  EFijw × Sij /SDij

where:
Eij is the fugitive emissions (other than emissions that are vented or flared) of gas type (j) being methane from the produced water during the year measured in CO2‑e tonnes.
Wi is the total quantity of produced water during the year associated with the relevant activity measured in megalitres of produced water.
