There are fresh concerns about the air quality at Stockton.
The latest test results show there are significant health risks for residents, with the concentration of very fine dust particles exceeding safety standards 13 times in less than 4 months.
The Stockton Community Action Group says PM10 dust levels are only supposed to exceed the standard 5 times a year, a figure put in place to allow for natural events such as bushfires.
Stockton residents are calling for the Environment Protection Authority to set up new air quality monitoring stations at Carrington, Mayfield, Stockton and Fern Bay.
