1. The main objectives of environmental management are:

  1. Sustainable use of the Defence estate by the implementation of responsible environmental practices.
  2. Compliance with Commonwealth Environmental Legislation, State and Local Government regulations and international agreements as required.

2. Because of the broad scope of its activities, ADFs impact on the environment may include land degradation, air and water pollution, unexploded ordnance, noise, and use of toxic and hazardous substances. Energy issues and the handling and transport of dangerous goods and munitions may also result in adverse impacts. Environmental attributes, such as endangered species, and cultural interests may be threatened by such impacts.

3. This chapter outlines the environmental considerations relevant to ADF aviation maintenance.


4. The 1995 Defence Environmental Review identified the following ADF environmental responsibilities:

  1. To comply with Australian obligations concerning environmental protection with respect to the conduct of ADF exercises and operations.
  2. To comply with Australian obligations in respect of the environmental management of ADF bases.
  3. To comply with Australian obligations in respect of environmental aspects of the design, construction, and introduction into service, operation and disposal of ADF equipment.
  4. To comply with Australian obligations in respect of energy management in the operation of ADF equipment, facilities, aircraft and vehicles.
  5. To consider noise and pollution aspects of ADF aircraft and other equipment.
  6. To comply with environmental and Work Health and Safety (WHS) aspects in the handling, storage, transport and use of ammunition, toxic and hazardous substances.

5. All members of the ADF are responsible to ensure that the ADF meets or exceeds its environmental responsibilities. It is incumbent for all ADF members to be familiar with their environmental responsibilities and to meet those responsibilities.

6. The responsibility for control of environmental management within the Defence Organisation lies with Defence Support and Reform Group (DSRG) in Canberra. Advice and authority regarding the implementation of a suitable system in order to effectively control and handle environmental issues at a local/Approved Maintenance Organisation (AMO) level (based on AS/NZ ISO 14001:2004—Environmental Management Systems) must be obtained from DSRG prior to implementation.


7. The CDF and commanders at all levels must continue to meet all legal and ethical obligations during the execution of ADF operations.

8. It is a particular characteristic of environmental legislation in Australia that the directors of a business, the senior staff, and even operating employees can be held responsible for contraventions of environmental legislation. With the introduction of the ‘National Environment Protection Council (Implementation of national environment protection measures) Bill’, ADF commanders will be subject to State or Territory regulatory obligations for a range of stringent environmental standards previously unregulated at the Commonwealth level.


9. To comply with the ADF requirement for reporting unplanned controlled extinguishing agent discharges, AMOs must in accordance with DI(G) LOG 4–3–022—Ozone Depleting Substances and Synthetic Greenhouse Gases Manual and DEFLOGMAN Part 2 Vol 3 Chapter 3—Management of Ozone Depleting Substances and Synthetic Greenhouse gases used in Fire Protection Systems report the occurrence of the discharge within five days.

10. Most common controlled extinguishing agents used in Defence include: Halon 1202, 1211 and 1301, BCF, FM 200NAF S–111 and Halotron. Further controlled extinguishing agents are listed in DI(G) LOG 4–3–022 and DEFLOGMAN Part 2 Vol 3.
