The Work Health and Safety (Mines and Petroleum) Amendment Regulation 2019 (NSW) amends the Work Health and Safety (Mines and Petroleum Sites) Regulation 2014 (NSW) and commence from 1 February 2020. Please find outlined below the amendments to the legislation and reasoning behind the revisions.

39 (40 and 55)Schedule 12Imposes a workplace exposure standard of 0.1 milligram per cubic metre of air for diesel particulate matter at mines and petroleum sites. A 12-month transitional period is provided to give industry the necessary time to adapt to the new requirement.This is considered necessary in NSW because an exposure standard has not yet been legislated either in Commonwealth or state work health and safety laws. The exposure value is recommended by the Australian Institute of Occupational Hygienists.
127Removes reference to repealed legislation and replaces with reference to current legislation.The Mine Subsidence Compensation Act 1961 (NSW) has been repealed and replaced by the Coal Mine Subsidence Compensation Act 2017 (NSW).
128 (179)Requires an operator to notify the regulator of the following high potential incidents: an uncontrolled fire on mobile plant that is in operation (whether operated directly, remotely or autonomously) a loss of control of heavy earthmoving machinery that is operated remotely or autonomously, including any failure of braking or steering spontaneous combustion occurring at the surface of a coal mine (including an underground coal mine).To enable the department to better target incidences in high priority areas which may not otherwise be reported. A factsheet will be provided with more information. 
Please note that spontaneous combustion at coal mines are currently classed as dangerous incidents. See related amendment to clause 179 applying provisions for dangerous incidents when it involves a serious risk of worker exposure.
129Remove requirement to provide the regulator at least one month notice before operations at a mine are commenced and the coordinates of exploration drill holes.To allow a mining operation to provide notice any time before it commences.
130 Schedule 9Remove reference to “quarterly” and refer to work health and safety (WHS) reports only.To allow the regulator to require WHS reports at different intervals (including annually) without requiring a quarterly breakdown.
139(2)Clarify the regulator can only be satisfied that an applicant is eligible for a practising certificate if they hold a relevant certificate of competence (or an interstate practising certificate) or otherwise meet the criteria specified by the regulator in a notice.To clarify the eligibility requirements of an individual to hold a practising certificate.
143, 157Schedule 13Make it an offence for holders of practising certificates and licences to fail to comply with conditions imposed on those practising certificates and licencesTo enable a more effective mechanism for the regulator to enforce compliance with low-level breaches without suspending or cancelling a practising certificate.

177(4) Schedule 12Changes the requirement for registration of an item of plant specified under the WHS (Mines and Petroleum Sites) Regulation to every five years. Schedule 12 provides a transition provision in which the amendment does not affect the expiry dates of registrations that were in existence immediately before 1 February 2020.To remove requirement for specified items of plant to be registered annually, consistent with the national position as per clause 272 of the model WHS Regulation.
179Creates requirement for spontaneous combustion to be notified as a dangerous incident only if there is exposure to a serious risk.To implement new notification arrangements for spontaneous combustion incidents notified under clause 179.
Schedule 3(3) Schedule 12Identifies the establishment, operation, alteration or decommissioning of a tailings storage facility (TSF) as a high-risk activity and specifies the information and documents to be provided in relation to that activity. New requirement applies to all mines other than: coal mines, and opal mines, and small gemstone mines, and mines at which the inundation or inrush of any substance would not reasonably be likely to result in an emergency situation or present a risk to the health and safety of workers and other persons.
Updates definition of emplacement areas (clause 3 definition) for consistency across all mines. Transition provisions are included in which notification as a high-risk activity (clause 33): does not apply to the continuing operation of a TSF that was in operation immediately before 1 February 2020. may be given any time within three months of 1 February 2020 for TSFs defined as a ‘transitional high-risk activity’. (Refer to the factsheet for more information).
To allow for early identification of issues and intervention, if required, consistent with those for emplacement areas at coal mines. A fact sheet has been prepared on the amendments for tailings and storage facilities. The transition provision is required as a consequence of amendments made to enable a smooth transition to their implementation.
