Mining Lease Proposal (MLP)

 No feedback from Government regarding Managed Aquifer Recharge  This has impacted our targeted timeframe  We will update WCCC on targeted timeframe when we receive advice from the Government  Terramin will release draft sections of the Mining Lease Proposal to the WCCC when confirmation from Government that Chapter conforms with the Ministerial Determination and applicable legislation  Our aim has been in the interim is to have the WCCC informed of the proposed MLP contents

Baseline Monitoring at BIHGP

 What we measured for

  • Total Suspended Particulates (TSP) - <50 micron
  • PM10 - <10 micron
  • Deposited Dust (Total Insoluble Matter) – any size
  • Background metals

Dust - compliance

 Dust is a recognised nuisance  Environmental Protection (Air Quality) Policy (EP Act) sets the standards for airborne dust  No Total Suspended Particulates / Dust deposition standards for SA

  • Standard practice - NSW Approved Methods for Modelling and

Assessment of Air Pollutants

Baseline

 Updated Baseline Reports in 2017  PM10 more variable than expected baseline results for 2017

  • Strathalbyn range 0.2 – 30.6 µg/m³
  • Woodside range 10.7 – 78.9 µg/m³
  • EPA 2006 Woodside 6 - 90 µg/m³

 Total Suspended Particulates variable with seasonal activities  Total Dust Deposition similar to other agricultural areas

  • 4 grams/m2/month is proposed for total

maximum including background (from

  • ther operations)

Management of Potential Dust

 Enclosing, vegetation, spraying, all examples of how to control

slide-16
SLIDE 16

TERRAMIN AUSTRALIA LIMITED

SLIDE No. 16

Site Design – increase vegetation moisture

 Irrigation systems  Perennial vegetation – green all year  Significant reduction of grasses with high fuel loads – phalaris  Native C3 and C4 grasses

SLIDE No. 17

Monitoring of Potential Dust

 Beta Attenuation Particulate Monitors – “BAM Units”

  • Live
  • Link to weather station
  • Can have alert systems in place
  • Example – wind direction, wind speed and increased dust can set
  • ff early warning alarms to change activities
  • Options – more mitigation or alter/stop “source” activity

 High Volume dust samplers – filters to go laboratory  Dust Deposition Gauges – monitor total dust over monthly average

SLIDE No. 18

Example – Olympic Dam

 OUTCOME: No adverse impacts to public health as a result of fugitive particulate emissions from BHP Billiton’s expansion activities at Olympic Dam  Real time monitoring with weather station – rapid response  Trigger Action Response Plan  1. Relocating activities – more distance to sensitive receptor  2. Redirecting mine rock haulage activities  3. Increasing frequency of dust suppression activities  4. Cessation of operations

Bird in Hand – Air Quality Strategies

 Water carts, sprinklers on exposed and disturbed soils (inc. IML)  Vegetate exposed soils as soon as practical, hydromulching, cover all soil bunds with vegetation (reduces air velocity on soil)  Ore – enclosed in silo rather than on ground  Tip points fully enclosed  Maintenance of haul roads with regular application of dust suppressant spray  Asphalted roads  Transfer of dry materials must be covered – silo, covered trucks to Strathalbyn, etc.

  • fire,
  • reduction in water supply, or

5 vehicles = 10 movements per day

 Employee vehicles – Cars

15 cars per shift (2 shifts per day) = 60 movements per day

Monitoring – Draft Outcome Measurable Criteria

 Independent investigation of all traffic accidents demonstrates that the mine

  • perator could not have reasonably prevented the accident from occurring.

 Investigation of all public infrastructure related complaints demonstrates that the Mine Operator did not cause or could not reasonably have prevented the incident from occurring;  All public infrastructure related complaints were acknowledged within 48 hours and closed out within 14 days to the satisfaction of the complainant or as agreed with the Chief Inspector of Mines.  Truck driver check sheets will be completed for all ore trucks leaving site to demonstrate loads are covered and in compliance with agreed hours of operation.  Daily inspection of entry/exit points demonstrates no build-up of dragout material at the site entrance on Pfeiffer Road is occurring.
