Project Update October 2021
Excelsior Reserve declared a James Hardie Legacy Site
In August 2020, City of Parramatta engaged specialist consultants to undertake soil testing within an area of Excelsior Reserve (also known as Excelsior Park or Darling Mills Creek Reserve), adjacent to a section of the Murri-Yanna walking track, North Rocks. Asbestos containing materials were discovered below the surface of the bushland reserve.
While air-monitoring undertaken during the investigations showed there was no immediate risk to the public, taking precautionary action Council closed the site to prevent soil disturbance and ensure the site remained safe.
Council and specialist consultants have continued investigating potential contamination at Excelsior Reserve North Rocks engaging with the Environment Protection Authority (EPA) to reassess the site and the surrounding areas.
For some years, the EPA and City of Parramatta Council have worked closely to identify and assess potential legacy fill sites based on available historical records and multiple lines of evidence. Investigations intensified following the release of a 2010 report prepared by the then Department of Environment, Climate Change and Water titled James Hardie Asbestos Waste Contamination Legacy, Summary Project Report.
New Site 52 – Excelsior Reserve, North Rocks
The EPA has undertaken a review of the area known as Excelsior Reserve, North Rocks. The review included historical aerial photos, anecdotal evidence from community members and results of Council’s own investigations in 2020.
These multiple lines of evidence conclude that part of Excelsior Reserve may be affected by legacy asbestos filling associated with James Hardie.
Council will continue to plan for the remediation of Council-owned lands within Excelsior Reserve, with work expected to continue throughout 2021. Council will continue to advise the community on the progress of this work with the usual letters, signage and website updates.
Where the EPA identifies the potential for adjoining residential properties to be affected by legacy asbestos filling, EPA officers will contact residents directly.

Project update May 2021
Interim treatment works – two stages of work starting 17 May 2021
Additional temporary works have been scheduled at Excelsior Reserve to ensure asbestos materials remain safely buried.
Starting Monday 17 May 2021, these works include the installation of additional safety fencing, and the laying of stabilised crushed sandstone over affected areas of the access trail, specifically those areas that have already been treated with geotextiles. This work will ensure that vehicles can safely use the service trail in the event of an emergency, or should urgent maintenance be needed in the area.
The work program
The work will occur in two stages. The first stage (17 May) will involve the installation of additional fencing, between the service trail and the lower embankment, and repair of the existing geotextile.
The second stage (approx. start date Wednesday 19 May) will involve the delivery and installation of a 100mm thick layer of crushed sandstone over areas of the service trail. The crushed sandstone will help stabilise the track for vehicles and will also offer a more robust interim cap over affected soils.
All work is expected to be complete in one week (weather and site conditions permitting).
Health and safety
All appropriate safety protocols including air-quality monitoring will be undertaken during the works, and protective equipment appropriate for each stage of works will be worn by all workers, in accordance with NSW SafeWork requirements.

Project update December 2020
Why are parts of Excelsior Reserve closed?
In August 2020, City of Parramatta engaged specialist consultants to undertake soil testing within the Excelsior Reserve, North Rocks. Asbestos containing materials were discovered below the surface of the reserve.
While air-monitoring undertaken during the investigations showed there was no immediate risk to the public, taking precautionary action Council closed the site to prevent soil disturbance and ensure the site remained safe.
In November 2020, consultants were engaged to conduct further soil testing and provide specialist advice to Council.
While there was no detection of airborne fibres during soil testing Council is taking specialist advice for interim and long-term remediation. Council is also consulting with NSW WorkSafe and NSW Environmental Protection Agency and will undertake regular inspections and implement air fibre monitoring around the embankment, to ensure that the area remains safe.
Test results
Laboratory analysis of the samples collected during testing found that asbestos containing materials, including fibro and friable asbestos (the waste by-product of manufacturing) were present within the top 100mm of the soil and exceeded the acceptable limits for open space and parks.
Friable asbestos material found in the bushland consisted of loose fibres of asbestos containing material/product that could be reduced to a powder if crumbled or crushed by hand.
How will these sites be managed?
NSW Health advises that asbestos presents a risk when fibres become airborne and can be inhaled.
While there was no detection of airborne fibres during soil testing Council is taking specialist advice for interim and long-term remediation. Council is also consulting with NSW WorkSafe and NSW Environmental Protection Agency.
Council staff and consultants will undertake regular inspections and implement air fibre monitoring around the embankment, to ensure that the area remains safe.
An environmental management plan will be prepared for managing the asbestos contamination on site. The plan will detail how workplace health and safety measures will be implemented on site.
What are the next steps?
Parts of Excelsior Reserve will remain closed. The City of Parramatta will take immediate action to improve site safety while planning for long-term remediation begins.
Council will implement additional measures to improve site security including the installation of 2.1m high chain-wire fencing and signage which complies with NSW WorkSafe requirements.
A geofabric layer to cover the site will be installed on the Service Trail and embankment to prevent the exposure of potentially contaminated material. Sediment fencing to contain soil disturbance will be installed within the bushland area.
A remediation plan for the embankment, Service Trail and bushland will be created.
Council will continue to provide updates on the progress of these actions on its website.
