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 outcomes to be

achieved in PEPR or 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 licences2) Access to Land3) Native Vegetation Legislation4) If required, payment of a Bond

Purpose:- Grant of mineral tenure and development approval

Purpose:- Operational approval


Stage 2 – The PEPROperational approvalThe purpose of the PEPR is to provide information demonstrating requirements of the lease can be met, and sets out 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 nuisance2) No loss of abundance or diversity of native vegetation3) No impacts to agricultural productivity


Air Quality

Monitoring (Measurement Criteria) from Lease:1) Public health

a) PM 10 – dust in air that is less than 10 micrometres in sizeb) PM 2.5 – dust in air that is less than 2.5 micrometres in sizec) Chemical and Toxicological analysis of dust

2) Public nuisancea) Total Suspended Particulate Matter (TSP)b) Total Dust Deposition (TDD)c) Directional Dust Deposition (DDD)

3) Meteorological Monitoring


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 nuisancea) 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)


Air Quality

Reporting requirements from Lease:

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


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”


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


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 or will be complied with


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


Noise Monitoring (Criteria)

• Noise measurements must follow procedures in the EPA Guidelineshttp://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

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


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


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


Blasting

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

a) Public Safetyb) Human comfortc) Third party property (including stock)d) Adjacent land usee) Aircraftf) Other receptorsfrom airblast, flyrock and vibration cause by blasting

2) No flyrock to encroach on third party property3) Notify property owners (subject to consent) no less than 48hrs prior


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 2187.22) Blast exclusion zone3) Blast protocol and schedule to be developed in consultation with residents within lease and adjoining the lease.
