Project Update WCCC February 2018 TERRAMIN AUSTRALIA LIMITED SLIDE - PowerPoint PPT Presentation

Project Update – WCCC February 2018 TERRAMIN AUSTRALIA LIMITED SLIDE No. 1

Project Update  EPBC Act Referral – Federal government assessed and determined “Not a controlled action’’  Not conditional  Received 7 th February 2018  Endangered orchids and listed ecosystems within the proposed ML not impacted by mining operations – aspects such as groundwater, dust, etc assessed  CSIRO – confirmed will continue through 2018 – Phase 2  No final report yet but Kieren to present results (April 2018) TERRAMIN AUSTRALIA LIMITED SLIDE No. 2

Community participation: Anchor to Pulse 4 (ALL) Invited Completed all 4 surveys 444 211 Responded  Strong engagement in the 2017 294 CSIRO Reflexivity process – 211 people completed all five surveys across 12 months+ Response Rate 66% TERRAMIN AUSTRALIA LIMITED SLIDE No. 3

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 TERRAMIN AUSTRALIA LIMITED SLIDE No. 4

Outcomes and Measurable Criteria  Outcomes and Outcome Measurable Criteria  So far WCCC has received o Groundwater o Air Overpressure o Surface water o Traffic o Noise o Fire o Vibration o Air Quality  Outcomes are set at Mining Lease Proposal (MLP) stage  Measurable criteria developed from now and over the Programme for Environmental Protection and Rehabilitation (PEPR) phase, - AFTER the MLP (if approved)  Government guidelines on how to propose outcome measurable criteria – link in meeting minutes  Proposed outcomes will form basis of Lease Conditions TERRAMIN AUSTRALIA LIMITED SLIDE No. 5

Outcomes and Lease Conditions – AZM Example how the conditions developed ML PROPOSED OUTCOME “Stabilise disturbed areas and prevent sediment from leaving the site” ML LEASE CONDITION “The Lessee must, in constructing and operating the lease and post mine closure, stabilise disturbed areas and prevent sediment from leaving the site” Measureable Criteria developed to demonstrate compliance with ML Outcome and Lease condition TERRAMIN AUSTRALIA LIMITED SLIDE No. 6

Outcome – proposed and finalised Measureable Criteria – draft now at Mining Lease Proposal but finalised through PEPR stage TERRAMIN AUSTRALIA LIMITED SLIDE No. 7

TERRAMIN AUSTRALIA LIMITED Air Quality – Dust Control

Types of Dust TERRAMIN AUSTRALIA LIMITED SLIDE No. 9

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 TERRAMIN AUSTRALIA LIMITED SLIDE No. 10

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 Ind ndic icator Pro Projec ect t Ob Objec ectiv ive Aver eraging Per Perio iod Envir ironmental l Valu lue TSP 90 µg/m³ 24-hour Amenity PM10 50 µg/m³ 24-hour Health 25 µg/m³ 24-hour PM2.5 Health 8 µg/m³ Annual 4 g/m²/month (maximum total deposited dust level) Dust deposition (Total Insoluble Annual Nuisance/ Ecological Matter) 2 g/m 2 /month (maximum increase in deposited dust level ) TERRAMIN AUSTRALIA LIMITED SLIDE No. 11

TERRAMIN AUSTRALIA LIMITED SLIDE No. 12

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/m 2 /month is proposed for total maximum including background (from other operations) TERRAMIN AUSTRALIA LIMITED SLIDE No. 13

Sources of Potential Dust  Dump trucks on surface – Mullock and Ore  Integrated Mullock Landform  Disturbed and cleared land  Construction sites  Vehicle emissions  Ventilation fans TERRAMIN AUSTRALIA LIMITED SLIDE No. 14

Management of Potential Dust  Enclosing, vegetation, spraying, all examples of how to control TERRAMIN AUSTRALIA LIMITED SLIDE No. 15

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 TERRAMIN AUSTRALIA LIMITED SLIDE No. 16

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 off 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 TERRAMIN AUSTRALIA LIMITED SLIDE No. 17

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 TERRAMIN AUSTRALIA LIMITED SLIDE No. 18

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. TERRAMIN AUSTRALIA LIMITED SLIDE No. 19

Proposed outcomes 1. No nuisance impacts to local residents from dust generated by construction, mining or closure activities. 2. No public health impacts to local residents from dust generated by construction, mining or closure activities. 3. No loss of productivity on properties surrounding the mining lease from dust generated by construction, mining or closure activities. 4. No permanent loss of abundance, condition or diversity of native vegetation (as defined by Native Vegetation Act 1991) on or off the lease during construction, operation and post mine completion through; • clearance, • dust/contaminant deposition, • fire, • reduction in water supply, or • other damage, unless prior approval under Native Vegetation Act 1991 and Native Vegetation Regulations 2017 is obtained.
