Code of Practice: Onshore Petroleum Activities in the Northern Territory

Last updated: 16 January 2020

Includes methane specific emission monitoring, leak detection and reporting requirements in the Northern Territory.

The scope of the code of practice for methane emissions covers:

- Pre-exploration and pre-operation baseline assessments;

- Routine periodic air monitoring;

- LDAR;

- Venting and flaring;

- Other emission sources from petroleum activities; and

- Reporting requirements.

The Code of Practice also outlines the types and requirements for methane monitoring. These include:

- Baseline Methane Assessments - This covers ambient methane levels before production. Measurement is to take place 6 months before production. In the case of hydraulic fracturing, this is to take place 12 months before productikon commences.

- Regional Methane Assessment Programs (RMAP) - This covers existing natural methane sources across permit sites. Measurement is to take place 6 months before production and in the case of hydraulic fracturing, 12 months before production commences.

- Routine Periodic Atmospheric Monitoring - Operates on a periodic basis for the life of the project. Routine monitoring of the whole facilitiy is to take place every 5 years, with monitoring equipment being installed 12 months before production begins.

Methane Emission Management Plan (MEMP)

This  must be submitted before production at an onshore petroleum project. The methane targets are to be in line with ALARP (as low as reasonably practicable).

To manage and detect fugitive emissions, inspection of well-pads should take place every 6 months with other equipment being inspected on an annual basis.

Venting and flaring should be either eliminated or minimised to as low as reasonably practicable.

This is governed by the Department of Primary Industry and Resources and Department of Environment and Natural Resources
