In 2019, we developed a discussion paper on diesel particulate matter.

We invited feedback from the mining industry regarding the application of a diesel particulate exposure standard for mines in NSW.

The Regulator sought comment on the following recommendations:

  • Supporting the introduction of 0.1 mg/m3 limit measured in the elemental carbon fraction into the WES list through SWA’s review process. This would mandate the exposure standard through cl 49 of the Work Health and Safety Regulation 2017.
  • Prescribing a limit of 0.1 mg/m3 limit measured in the elemental carbon fraction in the Work Health and Safety (Mines and Petroleum Sites) Regulation 2014, if SWA does not include diesel emissions in the WES or proposes a higher limit.
  • Updating MDG 29 to provide guidance on the requirements of a principal mining hazard management plan, specific to the operation of diesel engines underground, assessment and testing of compliance with the plan, and actions required, should the assessment reveal temporary and/or long-term deficiencies.
