Blacktown Council obtained an injunction against the second company accused of dumping demolition waste on an illegal tip at Hamilton Street, Riverstone last Wednesday.
It asked NSW Land and Environment Court to include Riverstone Waste Transfer Pty Ltd after it obtained an injunction against the first company, Penetrators Pty Ltd, on October 4.
A council spokeswoman said Riverstone Waste Transfer Pty Ltd would now be included in the proceedings for evidence to be presented on its involvement.
She said it also sought orders for the removal of the waste material at the cost of those found responsible.
The spokeswoman said the council had obtained an injunction against the two companies to prevent further dumping of material on the land.
‘‘Officers from Council and Environment Protection Authority have visited the site and found the injunctions effective,’’ she said.
‘‘The council will seek orders from the court for the two companies to remove the waste material at their own costs.
‘‘A hearing will take place on a date to be fixed by the Land and Environment Court.’’
She said the court would also determine the appropriate fine if it found the two companies guilty.
She said the council would be vigilant and act on all complaints from customers to ensure such an offence would not happen against.
‘‘It is hoped the outcome of this matter will send a warning to other people contemplating similar illegal actions.’’
