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.
Please contact us by email on PortPirie.Environment@nyrstar.com to find out more.
1.3. Changes at the Site or Trials
TRIALS PRE-TREATMENT BLAST FURNACE FEED
COMMUNITY INFORMATION: January 1, 2021
Nyrstar is about to start trials to test the pre-treatment of feed for the Blast Furnace that could result in a more rapid reduction of stockpiles on site.
The company wishes to advise that it plans to commence a plant trial during the week commencing 4 January 2021. The trial will be conducted on Weekdays for up to 2 months from the commencement date.
The objective of the trial is to pre-treat leach product to remove moisture and agglomerate feed for the Blast Furnace. The trial will provide critical data that can then be used to identify technical feasibility and what upgrades are required to allow the pre-treatment of leach product to enable a more rapid removal of current stockpiles from the site. This will subsequently also contribute to a reduction in lead and dust concentrations within Port Pirie.
Strict environmental controls approved by the Environment Protection Authority (EPA) have been put in place to control the environmental risks and as a result there is expected to be minimal impact within the community. The potential for increased dust emissions during the trial has been identified and additional monitoring and controls have been put in place.
The feed material has a low sulfur concentration that will be captured in the site industrial ventilation system and vented via the Tall Stack. The sulfur dioxide levels are anticipated to be well below historical levels during the trial and there is expected to be negligible impact on ground level concentrations within Port Pirie.
As noted above, the trial will only be conducted from Monday to Friday each week during the trial period to ensure that appropriate resources are available at all times to troubleshoot and respond to any incidents of dust and sulfur dioxide emissions that may be identified during the trial.
NOTIFICATION: 15/9/2020: DIG-OUT OF BASIN AND FIRST CREEK - Nyrstar Port Pirie has commenced a dig-out of the Sedimentation Basin. The use of a silt curtain will minimise the risk of any short term turbidity in the waste-water discharge during this exercise. No adverse impacts on people or the environment are expected. The dig-out is, however, expected to significantly improve the quality of the discharge water with benefits continuing for at least 6 months.
NOTIFICATION: 31/8/2020: Nyrstar Port Pirie is planning to conduct a trial on the use of clay to reduce metal concentrations in the wastewater discharge. Our laboratory test-work has indicated that a very small volume of clay at a concentration of about 1 part per 100,000 can remove a large portion of the dissolved metals in wastewater. We have EPA for approval to run the trial which has minimal environmental risk and great potential benefit. This trial will have no impact on the community.

3. Community Notifications
Monitoring data is publicly available on: Pi in the Sky website click here
3.1. Water Quality Notifications
Water quality is above the reporting threshold for Copper at the ‘1M Flume’, which is the point of discharge to First Creek.
Nyrstar has a project underway and expects the issue to be resolved in 2021.
3.2. Air Quality Notifications
NOTIFICATION OF EXCEEDANCE OF 12 MONTH AVERAGE LEAD IN AIR TARGET AND CORRECTION – 31 DECEMBER 2020
Reference is made to EPA Licence No. 775 issued by the South Australian EPA on 1 July 2020 to Nyrstar Port Pirie Pty Ltd (“Licence”). Capitalised terms used in this notification that are not otherwise defined have the meanings given to them in the Licence.
Nyrstar notifies for the purpose of section 1.5.2(a) of the Licence that the 12 month average TSP Lead in Air Target was exceeded in the 12 month period to 31 December 2020.
On 3 January 2021 Nyrstar notified that the 3 month average TSP Lead in Air Target was exceeded in the 3 month period to 31 December 2020. That notification was made as a result of a calculation error, which has now been corrected. Nyrstar did meet the average TSP Lead in Air Target in the 3 month period to 31 December 2020.
3.2.1. Lead in Air Limits
Lead in air concentration was above the 0.4 µg/m3 annual average limit at Pirie West compliance monitor on 31 December 2020.
Lead in air concentration was below the 0.4 µg/m3 annual average limit at Oliver Street compliance monitor on 31 December 2020.
3.2.2. Lead in Air Targets
Lead-in-air at the Ellen Street monitor was over the 1.6 µg/m3 annual average target on 31 December 2020.
Lead-in-air at the Boat Ramp monitor was over the 0.6 µg/m3 annual average target on 31 December 2020.
3.2.3. Sulphur Dioxide (SO2) Investigations
There have not been any exceedances of the 0.08 ppm 24-hour average investigation trigger.
There have not been any exceedances of the 0.02 ppm 12-month average investigation trigger.
3.2.4. Dust (PM10) Investigations
The average daily concentration of dust at the Boat Ramp TEOM on Saturday 12th December was 59µg/m3 which is higher than the 50µg/m3 NEPM target. Dust was mobilised by very strong wind gusts to 11.8m/s which were experienced ataround 11:00am. There were no visible plant emissions during the regional dust storm that occurred at this time.
