The discovery has stalled part of Lend Lease's Calderwood Valley project, while a clean-up is carried out.
The EPA has also ordered clean-ups at the Blue Mile Tramway in Wollongong, a section of Wattle Road at Shellharbour and private property in Yerrinbool.
The potentially toxic ' friable ' asbestos has been discovered in contaminated building material delivered to three of the sites by Wollongong Recycling, who's been ordered to gather it up and replace it with clean aggregate.
Only bonded asbestos was found at the Shellharbour site, but also needs to be cleaned out.
