We regulate greenhouse gas storage in Australian Commonwealth waters under the Offshore Petroleum and Greenhouse Gas Storage Act 2006 (the Act).
Australian Commonwealth waters start 3 nautical miles from the coastline and extend to the boundary of Australia’s Exclusive Economic Zone.
This includes offshore carbon capture and storage activities.
The Act is supported by 4 regulations that apply to both greenhouse gas storage and oil and gas activities:
Our regulatory role includes:
The Australian Government awards offshore greenhouse gas storage titles in Australian Commonwealth waters. The responsible Commonwealth Minister (RCM) is responsible for the administration of greenhouse gas injection and storage provisions. The RCM makes major policy decisions under the Act, including:
The National Offshore Petroleum Titles Administrator (NOPTA) and the National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA) perform regulatory functions for offshore greenhouse gas storage activities:
The Act describes how the petroleum and greenhouse gas industries coexist. In some circumstances, one activity could impact the other. To manage this, the legislation differentiates between pre-commencement petroleum titles and post-commencement petroleum titles.
A petroleum title includes:
Pre-commencement petroleum titles are any titles awarded a petroleum exploration permit before November 2008.
This includes titles where the retention lease and production licence were granted after this date.
Pre-commencement titles are protected by a ‘significant impact test’. Under this test, the RCM can only approve greenhouse gas activities if either:
Post-commencement petroleum titles are any titles awarded a petroleum exploration permit after November 2008.
If there is no agreement between a petroleum titleholder and a greenhouse gas titleholder and the 2 activities cannot co‑exist, the RCM decides which activity should proceed in the public interest.
All post-commencement petroleum production licenses are protected by the significant impact test.
For more information about pre-commencement and post-commencement titles email email@example.com.
The government releases offshore areas for greenhouse gas storage through the greenhouse gas storage acreage release.
Companies can nominate their areas of interest to the RCM for assessment. We consult the public before releasing offshore areas (acreage) for exploration.
The greenhouse gas storage acreage release is separate to the offshore petroleum exploration acreage release.
Subscribe to Australian Petroleum News for information on acreage bidding rounds. Subscribers will also receive updates on offshore greenhouse gas matters in Australian Commonwealth waters.
Permit holders must meet exploration requirements before starting offshore greenhouse gas activities in Australian Commonwealth waters. This includes having an environment plan assessed and accepted by NOPSEMA.
You may then begin exploring in their permit area. If you find a suitable site for permanent storage, you must apply for a declaration of greenhouse gas storage formation. If you are not ready to inject greenhouse gas you can apply for a greenhouse gas holding lease.
Injection and storage in a declared formation requires a greenhouse gas injection licence.
Greenhouse gas companies may consult stakeholders when preparing an environment plan, including:
Find information about consulting with Australian Government agencies on NOPSEMA’s website.
We are enhancing the framework for decommissioning and remediating offshore infrastructure. Existing requirements apply while we are doing this work.
Find the decommissioning strategy and operational policies on NOPSEMA’s website.
Carbon dioxide is a greenhouse gas substance. We regulate offshore carbon capture and storage (CCS) activities under the Act.
State and territory governments set out the regulatory framework for onshore CCS:
Onshore CCS includes activities within the coastline, up to 3 nautical miles from the baseline.
