Police say they won't be taking any action over the spilling of contaminated silt dredged from Peel harbour, on the town's roads.
Officers have taken specialist advice on whether the sludge spill created a hazard under European regulations on the transportation of dangerous goods.
But Chief Inspector Darrill Pearson says the threshold for action by the authorities was not reached - and officers have dealt with the matter in the same way as they would any other spillage on Island roads.
Police are reminding contractors, farmers and any other drivers who leave deposits on public roads, that they must act responsibly.
Under the Highways Act 1986 they're required to place warning signs and mop-up spills within a reasonable time.
There was an outcry earlier this month when silt leaked from a contractor's lorry on roads in a Peel housing estate, en route to Poor town, where it's being stored temporarily.
