(1) The Fremantle Port Authority (FPA) agreed to conditions in EPA Bulletin 771 of March 1995 titled "Seawall and Land Reclamation to Extend Rous Head - Changes to Environmental Conditions", that included Condition 7-2 "The proponent shall ensure that fill material is inert". (2) The FPA considers, on the basis of intensive laboratory testing of the silo concrete and advice from its environmental consultants, the material fits the EPA's definition of "inert" as published in EPA Bulletin 586 of October 1991. On the advice of the DEP, the FPA intends conducting a sea trial with a relatively small quantity of the silo concrete in order to confirm the material is inert.
