The decision follows the receipt of the finished Rutherford Odour Investigation Project, an independent report, which recommends comprehensive testing be undertaken on at least nine sites of the industrial estate.
Minister for the Environment and Heritage Robyn Parker said the NSW government is committed to addressing residents' concerns about potential odours near the industrial estate.
The EPA has taken on the advice and will today begin the process of advertising tenders for the odour sampling and modelling work.
