Lead Smelter, Port Pirie, South Australia

Client – Nyrstar
Services – Marine and Coastal, Flora and Fauna, Planning and Compliance, Community Consultation
Assignment – Located on the eastern shore of Spencer Gulf in South Australia, approximately 230 km north of Adelaide, the smelter has been in constant operation for more than 120 years. There is an adjacent dedicated port facility where concentrates are received, with final products dispatched by road and rail. Port Pirie is an integrated multi-metals recovery plant with the flexibility to process a wide range of lead rich concentrates and smelting industry by-products. Port Pirie is one of the world’s largest primary lead smelting facilities and the third largest silver producer, which allows it to generate significant economies of scale.
Our Role – Nyrstar commissioned COOE to develop and implement an annual 5 year Environmental Monitoring Program to provide Nyrstar with information on the health of key marine environmental indicators. This information can then be used to evaluate the effectiveness of Nyrstar’s environmental management systems. The program entailed the following:

    • develop and implement a marine-monitoring program that included assessing: concentration of metals in marine sediment and seston; metal accumulation in marine organisms; distribution, diversity and abundance of fouling organisms; seagrass, mangrove and samphire surveys; and thermal and salinity distribution patterns from creeks
    • vegetation surveys, revegetation planning and implementation
      provide temporary environmental support staff
    • investigate arsenical waste treatment options and assist in developing and implement a waste management program
    • develop a site water management plan
    • service and maintain air-monitoring equipment
    • model marine discharge water dilution gradients
    • auditing of environmental monitoring programs
    • design and implement a site rehabilitation program to reduce dust emissions and the site footprint
