4 key tools for your Targeted Action Response Plan

Highlights:

 

What is a TARPs?

What is a Trigger Action Response Plan (TARPs)?

The Trigger Action Response Plan (TARP) is a fairly common tool in the mining industry that is used for managing crucial situations from a mine operations safety point of view. A typical TARP document sets out a certain set of conditions or ‘triggers’ with a set of corresponding actions that mine managers and supervisors must follow when those trigger events occur. These plans can include a number of different trigger levels, each with a set of responsibilities assigned to mine personnel to action as required. The aim of TARPs is to provide guidance and clarity when a situation deviates from the original plan or there is a change in conditions that could be hazardous.

 

TARP’s for tailings storage facilities (TSFs)

How are TARP's used for tailings dams?

Implementation of Trigger Action Response Plans (TARPs) are an invaluable tool for monitoring and response procedures to ensure the safe operations of tailings storage facilities (TSFs). They describe what variations in instrument readings or observations warrant responses and what those responses or follow-up actions should be. TARPs cover the key inspection and monitoring items for TSFs along with actions for various triggers using traffic light assessment methods. TARPs should provide site-based personnel (e.g. TSF operators) clear and concise decision-making tools. Based on governance requirements, TARPs are recommended at all mines sites operating TSFs (and other high-risk dams).

 

How to developing a TARP

What are the fundamental principles that TARPs should include?

According to David Cliff, the TARPs must be simple and robust; they must be adequately resourced both in terms of personnel and equipment; their focus should be on prevention and control through early detection; setting trigger values require detailed knowledge of what is normal, they need to be regularly reviewed; there is no substitute for high quality mine environment monitoring systems; they should be set based on the best available advice-both on site and off site, and if a TARP mandates an action, then that action must be carried out properly and promptly.

A TARP typically consists of three or four levels related to indicators of the level of risk posed by the hazard in question. Techniques for measuring the indicator should be reliable, and the trigger levels must be easily obtained, in a short timeframe, to enable prompt action.

  • Level 1 of a TARP is ‘normal’, where current procedures and practices maintain the risk at a level that is currently acceptable to the operation. However, this does not prevent any efforts to further reduce the level of risk.
  • Level 2 of a TARP is an ‘alert/investigate’ level, where the risk level indicator has deviated from normal. The level of the deviation is such as to cause increased investigation of the reason(s) for the change and an increased vigilance or control efforts. Actions at Level 2 are likely to contain the mobilisation of additional resources, increased monitoring and the deployment
    of additional controls to prevent increasing risk.
  • Level 3 is a ‘high alert/rectify’ level, where the indicator has reached a level at which the focus shifts from investigating the cause to managing the preparations for withdrawal. However, this does not mean that all efforts at control are abandoned. Indeed, more extreme control measures may be pursued.
  • Level 4 is the ‘withdrawal/removal’ of personnel from an environment that poses an unacceptable risk.

 

4 tools to incorporate into your TARP

The use of real-time monitoring tools enables you to better assess the situation and provides greater clarity towards developing effective trigger values.

The four tools to consider incorporating into your TARP are:

  • Environmental monitoring
  • Obligations
  • Wasterock landforms
  • InSAR

1. Environmental Monitoring

Environmental monitoring is crucial in understanding environmental health, efficiencies, constraints and upholding compliance, and when done well, can have a positive impact on the bottom line of an operation. Often these datasets are large, complex, stored in different locations, and details can be lost with staff turnover.

Decipher’s Environmental Monitoring & Sampling module provides you with all of the tools you need to manage your project-specific data requirements and insights to help drive effective environmental monitoring.

  • Create any number of points, parameters and compliance limits and group them to form monitoring programs such as soil, dust, water, vegetation, erosion, vibration, weather and more
  • Visualise this data and the results with traffic light colouring to indicate values and drill down into points by extracting historical data, such as charts and tables
  • Easily build any number of compliane limits and standards into the monitoring tool and plot them in charts and tables to flag exceedances
  • Create a schedule of sample jobs with predefined due dates and sample types with the ability to incorporate a second layer of approval and escalation for overdue samples
  • Seamlessly integrate with any external or internal laboratory for automatic result validation and import with live alerts of exceedances

 

2. Obligations

Projects that directly impact the environment and community are often accompanied by a large volume of prescriptive conditions and actions that must be complied with in order to commence and continue a project.

Decipher’s Obligations module provides a central, online platform designed to capture important obligation information, enabling you to identify, address and manage key deliverables.

Environmental Obligations | Mine Rehab - Decipher Australia

  • Maintain a central library of all prescribed conditions and capture important information such as compliance status, category and risk
  • Assign obligation related actions to accountable team members with the ability to incorporate a second layer of approval and escalation for overdue actions
  • Decipher’s API driven design allows users to exchange information to and from external data sources and systems such as regulatory databases, action management, safety solutions and more

 

3. Wasterock landforms

Designing long-term, stable wasterock landforms (WRL) that resist erosional landforms and degradation is closely linked to their structural geometry, such as slope angle, height and length.

Decipher Geometry is a remote sensing approach for the measurement of WRL geometry that allows for early identification of areas not constructed to design, and for preemptive implementation of remdial work.

Module - Landform & Erosion - Decipher

  • You can easily identify and measure landform geometry such as batterns, berms, crest bunds as well as erosion gullies
  • Visualise landform geometry and erosion gully measurement outputs over time in a 3D interactive view or alternatively, you can import any type of LiDAR dataset for basic viewing and measurements
  • In conjunction with other modules, you can also assess how the landform is affecting its surrounding environment
  • Assign wasterock landform related preventative and corrective actions to accountable team members with the ability to incorporate a second layer of approval and escalation of overdue actions

 

4. InSAR

Interferometric Synethic Aperture Radar (InSAR) is a remote sensing technique used to detect, monitor and measure the magnitude of deformation in land surfaces over time utilising Synthetic Aperture Radar (SAR) imagery. Understanding the extent and magnitude of such movement helps to identify and manage risk of potential failures and provide assurance that the area is safe and stable.

Decipher’s InSAR module provides a way to visualise displacement (cm) on an interactive map to enable users to identify specific areas of deformation across a broad range of interest.

InSAR - Decipher

  • Our easy to use cloud solution enables you to monitor, measure and detect deformation of land surfaces over time and be automatically alerted to customer defined exceedances to a precision of 1-2 millimetres
  • Draw a transect line across an area of interest or select a point on the map to display total displacement (cm) at each point over time in an exportable chart
  • Analyse areas of interest of 1,500 square kilometers each and generate tens of millions of data points per area to provide a better understanding of the extent of movement
  • Set a maximum displacement threshold to flag any exceedances on the map
  • Assign subsidence related preventative and corrective actions to individuals with the ability to incorporate a second layer of approval and escalation of overdue actions
