This webpage publicly presents information about our environmental plans and performance consistent with our commitment to transparency.


1.    Consultation on our environmental plans and projects
1.1. Environmental Management Plans

At Nyrstar Port Pirie, we prepare a range of plans covering environmental management. The following plans are available on request.

  • Community Engagement Plan
  • Dust Management Plan
  • Lead in Air Monitoring and Reporting Plan
  • Ground Level Particulate and Sulphur Dioxide Monitoring and Reporting Plan
  • Lead in Air Monitoring and Reporting Plan
1.2. Environment Improvement Programme

Nyrstar’s Environment Improvement Plan was approved by the EPA SA  (Environment Protection Authority) on 22 December 2020. This plan is available on request.

1.3. Proposed Site Trials or Process Changes

Pre-Treatment Plant Trial

From July 2021, Nyrstar will conduct a Pre-Treatment Plant trial to implement, validate, verify and monitor control measures intended to further optimise the process stability and improve dust control to enable sustainable operation. The plant would operate 24-hours per day and seven-days per week to test its environmental performance (dust emissions) under the prevailing northerly wind conditions during the proposed trial period.  One of the objectives is to verify the effectiveness of environmental control measures under various weather conditions.

The Pre-Treatment Plant trial will utilise a strand that is designed to accept high temperature material.  The goal of the process is to remove chemically bound water while retaining sulphur in the dried material.  This material will then be a supplementary feed for the blast furnace to ensure stable operation while providing a valuable sulphur source for the blast furnace.

The benefits of this include:

  • Improved emission stability from a Blast Furnace operating at optimal rate with consequent lower emissions of lead-in-air;
  • Consumption of an additional 400 tonnes/ day of Paragoethite (PG) which would reduce stockpiled volumes by an additional 146,000 tonnes per year allowing quicker depletion of stockpiles; and
  • Employment opportunity for 30+ people, further improving the community employment rate.

There are no other proposed site trials or process changes at present. Please contact us by email on to find out more.

Daily Average

There were no exceedances of the 0.08 ppm 24-hour average investigation trigger in the past month.

Annual Average

There were no exceedances of the 0.02 ppm 12-month average investigation trigger in the past month.

3.2.3. Dust (PM10) Investigations

Daily Average

There were no exceedances of the 50 microgram per cubic metre 24-hour average investigation trigger in the past month.
