Terror St concreter fined for slurry leak

14 Feb 2019

Environment Protection Authority Victoria (EPA) has fined a concrete supplier and ordered a clean-up, after a concrete slurry leak at a facility in Terror St, Keilor Park.
EPA Metro Region Manager Dan Hunt said the leak released highly alkaline concrete slurry into neighbouring land, leaving dried concrete and killing off vegetation.
“The leak had the potential to impact plants, fish and other forms of aquatic life,” Mr Hunt said.
