Notes
Elements and Performance Criteria
1. Plan and prepare for drill site preparation
  • 1.1. Access, interpret and apply drill site preparation documentation and ensure the work activity is compliant
  • 1.2. Obtain, read, interpret, clarify and confirm the drill site layout plan to confirm the location, size and configuration of the proposed drill site
  • 1.3. Identify and address potential risks, hazards and environmental issues, and implement control measures
  • 1.4. Select and wear personal protective equipment appropriate for the work activities
  • 1.5. Establish communication system and protocols
  • 1.6. Carry out plant and equipment pre-start checks
2. Create access to drill site
  • 2.1. Identify existing tracks and use for entry to drill site
  • 2.2. If necessary, create new tracks which minimises water flows and erosion by following the natural contours of the land
  • 2.3. Create new tracks to drill site which minimise the clearing of vegetation by avoiding large trees and preserving root stocks
  • 2.4. Raise blades to a minimum of 150mm when using machinery to prepare access blade
  • 2.5. Cut or trim larger trees if unavoidable
  • 2.6. Stockpile or windrow cleared vegetation for use during site rehabilitation
3. Prepare drill site
  • 3.1. Clear drill site removing minimum vegetation
  • 3.2. Seek permission from appropriate person to move hole location if vegetation significantly impedes access to the proposed drill site
  • 3.3. Manually clear ground cover to prevent fire hazards to drill rig
  • 3.4. Leave mature trees undisturbed
  • 3.5. Build sumps and bunds on the downside of the hole collar location
4. Minimise impact of contaminated groundwater
  • 4.1. Identify the possible presence of groundwater which may be a threat to vegetation during drilling operations
  • 4.2. If groundwater is discovered, construct appropriate number of sumps to recommended configuration and distances from the drill rig location
  • 4.3. Store topsoil removed from sump construction separately to facilitate more effective rehabilitation
5. Manage rare flora
  • 5.1. Determine the presence and type of rare flora before clearing vegetation,
  • 5.2. Seek advice on the action to be taken where rare flora are identified
