Schedule of disturbance for mining activities

This template should be used to present the calculations when proposing the amount of financial assurance under the Environmental Protection Act 1994. This template has been designed for use by environmental authority holders who undertake mining resource activities, and to allow for the varying phases of rehabilitation and the associated costs.

1Related documents

This template should be used in conjunction with the guideline Financial assurance under the Environmental Protection Act 1994 (ESR/2015/1758[1]). Related forms include:

  1. Application for a decision about the amount and form of financial assurance payable (ESR/2015/17541);and
  2. Application to amend or discharge the financial assurance held for an environmental authority (ESR/2015/17521).

2Explanatory notes

This section provides further details and definitions to assist EA holders completing the schedule of disturbance table overleaf.

  1. Disturbance category—Each row should include the activity type that will result in significant disturbance.
  2. Rehabilitation category—Outlines the appropriate steps of rehabilitation for which an annual cost will apply.
  3. Established—Once the rehabilitation work has been completed it is expected that responsibility for the rehabilitated area continues to require management (e.g. weeding) for a period of 3 years, after which the area may be considered successfully rehabilitated and rehabilitation work is no longer needed. Information on what the department considers successful rehabilitation can be found in the guideline Rehabilitation requirements for mining projects (ESR/2016/18751).
  4. Unit rehabilitation costs—This column should be used to record the cost of carrying out rehabilitation work in dollars ($) per hectare (ha) of disturbance.
  5. For disturbance categories the costs should be associated with all activities necessary to stabilise and re-establish the landform, this should include removal of infrastructure, excavation or back filling.
  6. For rehabilitation categories the costs should be associated with stabilising topsoils and establishing vegetation and should include recontouring landform, re-establishing soil profiles, seeding and management of established vegetation (weeding/fencing).
