In the Northern Rivers area, which is part of the Clarence Moreton Basin, three companies – Metgasco, Arrow and Red Sky – are currently involved in exploration for coal seam gas.
Some of the environmental concerns outlined by Mark Byrne in his presentation included:
- Potential contamination of groundwater
- Disposal of water produced during drilling (This water could contain salt, naturally occurring heavy metals, plus chemicals used in the drilling and fracking process – if fracking is used.)
- Effects of floods on evaporation ponds used to store produced water
- Release of methane (a very potent greenhouse gas) into the atmosphere
Other matters discussed in the seminar included petroleum law basics for both exploration and production, landholder rights and what could be done with regard to increasing safeguards to protect the community.
