COVID-19 alert: Read about eased restrictions for businesses in Greater Brisbane from 1am, Friday 22 January.
Joint interaction management plans
All overlapping coal and coal seam gas (CSG) operations require a joint interaction management plan (JIMP) to identify and control the hazards and risks of the overlapping operations.
This requirement is set out in the Coal Mining Safety and Health Act 1999 and the Petroleum and Gas (Production and Safety) Act 2004.
The requirement applies to all combinations of overlapping coal and CSG resource authorities (including those under the Petroleum Act 1923) where activities at an operating plant (other than a coal mining-CSG operating plant) could adversely affect the safe current or future mining of coal in the overlapping area.
Relationship to safety management systems
An agreed JIMP becomes part of the safety and health management system of the coal mine and part of the safety management system for each applicable operating plant in the overlapping area.
Note: An agreed JIMP, or arbitrated outcome, does not affect the authority of the Mining Inspectorate or Petroleum and Gas Inspectorate to take necessary compliance action to ensure safety and health concerns are addressed.
The development of the JIMP is the responsibility of the:
- site senior executive (SSE) for the coal mine
- the petroleum and gas resource authority holder (i.e. the operator of an authorised activities operating plant) in consultation with each operator of an applicable operating plant in the overlapping area.
The SSE and the operators must consult and agree on a JIMP that will apply at the coal mine and to the CSG operations in the overlapping area.
Either party can initiate the process by sending a copy of the proposed JIMP to the other party. The other party must respond with 20 business days. If agreement cannot be reached within 3 months, the dispute must be submitted for arbitration.
To ensure that all CSG hazards are identified and controlled, the CSG operators must coordinate their input into the JIMP before reaching agreement with the coal mine's SSE.
Application to new overlapping operations
The JIMP must be developed before the start of operations.
If a JIMP cannot be agreed upon within 3 months of it being proposed to the other party, the matter must be submitted for arbitration.
Content of a JIMP
The JIMP must comply with all legislative and regulatory safety requirements.
It must contain at least the matters stated in:
- s. 705C of the Petroleum and Gas (Production and Safety) Act 2004
- s. 64F of the Coal Mining Safety and Health Act 1999.
The JIMP must identify:
- each initial mining area (IMA), rolling mining area (RMA) and simultaneous operation zone (SOZ), if any, in the overlapping area
- hazards and risks to be controlled and triggers or material changes which must be monitored and which will require the JIMP to be reviewed
- response procedures and times and reporting procedures
- proposed or likely interactions with other persons in the overlapping area and associated risks from the interactions
- safety responsibilities of each person including the names of key safety persons.
The JIMP must also describe the way in which the SSE and the operators intend to communicate about, and coordinate, their obligations in respect to:
- incident response
- induction training
- information exchange
- vehicle safety
- any agreed alternative safety requirements applying to boreholes.
Reviews and revisions
The JIMP must be reviewed and revised through ongoing consultation if there are changes to operations in the overlapping area, or for other reasons, including if a risk control measure did not control the risk it was intended to control.
