Two Stage Mining Assessment Process

Apply for Mining Lease by submitting a Mining Proposal (s34 / s35) Public Statutory Consultation on Mining Proposal (s35A) DPC Assessment of Environmental Impacts from Mining Proposal and Consultation (s34 / s35) Lease granted with conditions and

• utcomes to be

achieved in PEPR

• r refused

(s34 / s35) Approval of Program for Environment Protection and Rehabilitation (PEPR) Mining Operations can commence

Stage 1 – Mining Lease – Completed Stage 2 - PEPR

Operations can commence subject to: 1) Other permits and licences 2) Access to Land 3) Native Vegetation Legislation 4) If required, payment of a Bond

Purpose:

• Grant of mineral tenure and development approval

Purpose:

• Operational approval

Department of State Development

Stage 2 – The PEPR Operational approval

The purpose of the PEPR is to provide information demonstrating requirements of the lease can be met, and sets

• ut the strategies to achieve the environmental outcomes determined through the lease application process.

PEPR must include:

• Description of operations, mining, rehabilitation and closure plans
• Environmental Outcomes (level of impact) including completion outcomes
• Measures for achieving the Environmental Outcomes
• Measurement Criteria (Operations & Completion) and Monitoring Plans
• Leading Indicator criteria (where applicable)
• Results of Consultation
• Consideration of Lease conditions
• Operator Capability
• Calculation of the max. rehabilitation liability to inform the Bond

Key considerations in a PEPR assessment:

• Does the evidence provided in the PEPR demonstrate the:
• Effectiveness of control measures for ensuring achievement of the approved outcomes (level of impact)
• Effectiveness of criteria in measuring the approved outcomes (level of impact)?
• Operator capability to implement the measures and management plans?

Government requirements for a PEPR

Government requirements for PEPR’s for Mining Metallic Minerals are set out through the Ministerial Determination (MD005) and Guideline (MG2b).

Air Quality

Environmental Outcomes from Lease: 1) No impacts to public health and public nuisance 2) No loss of abundance or diversity of native vegetation 3) No impacts to agricultural productivity

8

Department of State Development

Air Quality

Monitoring (Measurement Criteria) from Lease: 1) Public health a) PM 10 – dust in air that is less than 10 micrometres in size b) PM 2.5 – dust in air that is less than 2.5 micrometres in size c) Chemical and Toxicological analysis of dust 2) Public nuisance a) Total Suspended Particulate Matter (TSP) b) Total Dust Deposition (TDD) c) Directional Dust Deposition (DDD) 3) Meteorological Monitoring

9

Department of State Development

Air Quality

Monitoring (Measurement Criteria) from Lease: 1) Public health a) PM 10 < 50 ug/m3 as a 24 hour average (includes background) b) PM 2.5 < 25 ug/m3 as a 24 hour average (includes background) 2) Public nuisance a) Total Suspended Particulate Matter (TSP) < 120 ug/m3 for all 24 hour periods < 90 ug/m3 for all 12 month periods b) Total Dust Deposition (TDD) < 2 grams / m2 / month (mine contribution) < 4 grams / m2 / month for all 12 month periods (includes background)

10

Department of State Development

Air Quality

Reporting requirements from Lease: 1) Real time monitoring data to be reported on the Internet for: a) PM 10 b) PM 2.5 c) Meteorological data

11

Department of State Development

Air Quality

Strategies from Lease for Rex to Address in PEPR: 1) “Undertake continuous dust and meteorological monitoring to inform decisions for operational response and contingency measures to be implements to prevent exceedance of compliance criteria” 2) “Progressive rehabilitation and stabilisation of disturbed areas …” Compliance from Lease: 1) “In the event that monitoring shows …. a breach, the tenement holder must immediately cease the activity which resulted in the breach”

12

Department of State Development

Rainwater Tank Testing

• Tenement Holder must offer to test tanks
• Then test tanks for those who accept the offer
• Report results against Aust. Drinking Water Guidelines
• 4km based on location in relation to nearest communities
• Compliance with Lease condition is minimum legislation

requirement

13

Department of State Development

Rainwater Tank Testing

• March 2015 – Rex offered to undertake rainwater testing
• This satisfied Condition 8.1
• The PEPR must include details about how this condition has been
• r will be complied with

14

Department of State Development

Noise

• EPA Environment Protection (Noise) Policy 2007 sets noise

limits based on the land uses (zoning) in the relevant Development Plan

• Council zoning at the time of lease grant applies
• Lease sets the noise criteria to be achieved at receptors

15

Department of State Development

Noise Monitoring (Criteria)

• Noise measurements must follow procedures in the EPA Guidelines

http://www.epa.sa.gov.au/data_and_publications/standards_and_laws/environment_protection_noise_policy

• Independent acoustic engineer report on annoying characteristics
• Adjust noise measurements if annoying characteristics are present
• Noise can be measured ‘for or at’ sensitive receptors
• Monitor noise on a continuous basis, and report noise and

meteorological data in real time on a public website

16

Department of State Development

Noise strategies – 6th Schedule – Condition #7

• Best practice is expected
• As a minimum, implement the mitigation strategies described in

the Proposal and Response Document

• Investigate & implement additional design and engineering

measures

• Proactive measures – continuous noise and met. monitoring to

inform decisions for operational response and contingencies

17

Department of State Development

Noise strategies – EML 6th Schedule – Condition #3

• “the Tenement Holder must ensure that separation distances

between any extractive stockpiles and Pine Point ensure the achievement of the (noise) outcome”

• Ensures the handling of stockpiles will be undertaken away from

sensitive receptors

• Location of stockpiles must be shown in the PEPR

18

Blasting

Environmental Outcomes and Conditions from Lease: 1) No adverse impacts to:

a) Public Safety b) Human comfort c) Third party property (including stock) d) Adjacent land use e) Aircraft f) Other receptors

from airblast, flyrock and vibration cause by blasting 2) No flyrock to encroach on third party property 3) Notify property owners (subject to consent) no less than 48hrs prior

19

Department of State Development

Blasting

Monitoring (Measurement Criteria) from Lease: 1) Monitoring n accordance with Australian Standard AS 2187.2 Strategies from Lease for Rex to address in PEPR: 1) In accordance with Australian Standard AS 2187.2 2) Blast exclusion zone 3) Blast protocol and schedule to be developed in consultation with residents within lease and adjoining the lease.
