► NYRSTAR LICENCE RENEWAL

Port Pirie community update #2

Issued 30 June 2020

With the renewal of Nyrstar’s environmental

licence, the EPA is progressively introducing

sustainable lower emissions requirements

and significantly improved public access to

information. Strengthened conditions have

been developed using the benchmark of

modern licences. The EPA has given Nyrstar

the opportunity to be consulted, and the

licence has been issued for one year so that

conditions can be reviewed again when

further improvements at the plant take effect.

When imposing conditions on any licence,

the EPA must consider economic, social and

environmental aspects in accordance with

the objects of the Environment Protection

Act 1993. A summary of the strengthened

conditions are outlined overleaf.

New licence at a glance:

A 20% reduction in annual average Lead-In-Air (LIA) limits measured daily.

Rolling three month average LIA targets, to be assessed monthly from December, to focus efforts on reducing frequency, duration and intensity of shorter term emission events.

Requirement for an updated EIP, developed in consultation with the community, to address not only dust and lead emissions but also to establish actions to rectify and avoid future exceedences, and timeframes and milestones for improvements in wastewater management.

Increased public accountability for emissions to air and water – with requirements to provide public notification as well as to the EPA, and a requirement to provide an explanation of what caused any exceedence above targets imposed and the actions being taken to rectify them.

More data provided in real time with public accessibility.

Feedback loops from monitoring and reporting to revise the Environmental Improvement Program for continuous improvement.

Strengthened licence conditions from 1 July 2020

Aspect Status Explanation

IMPROVED, 20% LOWER

LIA LIMIT

TSP LEAD 12 MONTH AVERAGE LIMITS

Not exceed a 12-month average TSP Lead-In-Air limit of

0.4 µg/m3 (TSP Lead) based on the daily measurements

of Lead-In-Air at the Licensee's Oliver St and Pirie West

monitoring stations, with 4 compliance dates during the

year.

IMPROVED REPORTING TSP LEAD 12 MONTH AVERAGE TARGETS

OF PERFORMANCE All reasonable and practicable measures to not exceed a 12-month average TSP LIA target of 1.6 micrograms per cubic metre of air (µg/m3) based on the daily measurements of LIA at Ellen St Monitoring Station and 0.6 µg/m3 at Boat Ramp Monitoring Station.

Where a 12-month LIA target is exceeded provide public notification and notification to the EPA within 72 hours of laboratory confirmation, as well as a summary report to the EPA within 5 business days detailing the measurements, known reasons, and remedial action to eliminate future occurrences.

IMPROVED FOCUS ON TSP LEAD 3 MONTH AVERAGE TARGETS

SHORTER TERM EVENTS All reasonable and practicable measures to not exceed a rolling 3-month average TSP LIA target of 0.45 µg/m3

based on the daily measurements of TSP Lead at the Oliver St and Pirie West Primary School Monitoring Stations, 2.2 µg/m3 at the Licensee’s Ellen Street Monitoring Station, and 1.0 µg/m3 at the Boat Ramp Monitoring Station.

Where a rolling 3-month average TSP LIA target is exceeded provide public notification and notification to the EPA within 72 hours of laboratory confirmation, a summary report to the EPA within 5 business days detailing the measurements, known reason/s, and remedial action to eliminate future occurrences.

IMPROVED QUALITY OF

ensuring the minimum data return for daily TSP leadsamples from monitoring stations is not less than90%
