Acoustic modeling and environmental noise assessments are carried out regularly at our Birkenhead Plant in accordance with our Environmental Improvement Plan (EIP). The aim of these studies is to provide a more accurate picture of noise scenarios, ranking problematic noise sources and providing a basis for the EIP noise reduction program.

Noise sources specific to the Birkenhead Plant are identified and the sound intensity of each source is measured. These sources are then modeled and assessed against the South Australian Environment Protection Noise Policy 2007 for industrial noise compliance. Proposed changes are also measured against these criteria.

We also undertake a survey during times of reduced activity to understand levels of external noise impacts.

New Noise Abatement Projects Identified

A compressive night-time noise study was conducted by Adelaide Brighton Cement and leading independent noise consultants in the second half of 2016 to identify the next phase of noise abatement projects for the site.

Parts of the major plant and equipment (predominantly fans) were turned on and off and measurements were taken in the adjacent community. The study recommended proceeding with noise abatement of two dust collector fans located on the mid-level on the west side of the plant, adjacent to Victoria Road, and the refurbishment and harmonisation of the site's three largest plant fans.

Two new noise abatement silencers to fit the two fans were installed during the March 2017 shutdown, while refurbishment of the site's three largest plant fans was also completed.

Dust Collector

Completed Noise Reduction Projects

Four major noise improvement projects totaling more than $1 million were completed in early 2016 during our annual maintenance shutdown. These projects have significantly reduced noise levels in the adjacent community.

1) The operational chain assembly of the Limestone Reclaiming Conveyor System in the limestone shed has been replaced.The chain has a length of 400 meters and weighs approximately 150 tonnes and is key part of the limestone reclaiming process. Community feedback has been very positive, with some noting that "noise can no longer be heard" from the chain assembly.

2) Installation of an energy efficient and quieter motor system in the Cement Mill 1 Dust Collector has been completed, resulting in a significant noise reduction.

3) An upgraded noise reduction silencer in Stack 4B has been installed.

4) The design, manufacture and installation of an effective noise abatement solution for the Cement Mill Compressor building has been completed, resulting in noise no longer being heard from the original outlet source.

Noise Reduction Improvement Program

A key focus of our environmental improvement program in 2016 was the implementation of projects to reduce noise emissions from the Birkenhead plant. Our objective has been to discuss with the community our priorities for noise impact, and then take a range of actions to reduce noise.
