There were claims that the waste at Reids Road contained unacceptable levels of hexavalent chromium.
In a statement, the NSW Environment Protection Authority said given the potential for serious environmental risks if hexavalent chromium was present, the EPA did targeted testing for that element.
"The results show that there was no hexavalent chromium detected in any of the samples taken by the EPA," the statement said.
The council is proceeding with more comprehensive testing of each stockpile to determine whether there are suitable options for reuse or whether disposal is needed.
This depends on each type of waste meeting the environmental criteria for the proposed use and could include some of the waste being reused in road making under the excavated public roads material order and the excavated public roads material exemption 2014.
The waste will remain in stockpiles with standard environmental controls until it is ready to be reused or removed.
The council has given the EPA a commitment to continue to follow the EPA's protocols for assessing and classifying waste for reuse.
