Elements and Performance Criteria
- Plan for drill site preparation
- Access, interpret and apply compliance documentation relevant to the work activity
- Access the drill site layout plan to confirm the location, size and configuration of the proposed drill site
- Identify, address and report potential hazards and risks
- Select and wear appropriate personal protective equipment
- Establish communication system and protocols
- Carry out plant and equipment pre-start checks
- Create access to drill site
- Identify existing tracks and use for entry to drill site
- If necessary, create new tracks which minimises water flows and erosion by following the natural contours of the land
- Create new tracks to drill site which minimise the clearing of vegetation by avoiding large trees and preserving root stocks
- Raise blades to a minimum of 150mm when using machinery to prepare access blade
- Cut or trim larger trees if unavoidable
- Stockpile or windrow cleared vegetation for use during site rehabilitation
- Prepare drill site
- Clear drill site removing minimum vegetation
- Seek permission from appropriate person to move hole location if vegetation significantly impedes access to the proposed drill site
- Manually clear ground cover to prevent fire hazards to drill rig
- Leave mature trees undisturbed
- Build sumps and bunds on the downside of the hole collar location
- Minimise impact of contaminated groundwater
- Identify the possible presence of groundwater which may be a threat to vegetation during drilling operations
- If groundwater is discovered, construct appropriate number of sumps to recommended configuration and distances from the drill rig location
- Store topsoil removed from sump construction separately to facilitate more effective rehabilitation
- Manage rare flora
