It is easy to see why residents fear their health is at risk, given EPA evidence of excessive dust and health department warnings to stay inside on hot, windy days.

As reported by Fairfax last week, air quality monitoring by the EPA found dust particles exceeded acceptable levels [50 micrograms per cubic metre] on 13 days out of 100.

But in the wake of a community outcry, things began to change.

Sunshine Groupe general manager Christian Buxton received an email from Brimbank Council giving him the go-ahead to seal Bunting Road.

"We'll be doing it," Mr Buxton said. It's going to cost around $50,000 to do it.

"A full VicRoads-approved upgrade ... you're looking at $600,000 to do the whole road. It'll certainly have a significant impact on dust conditions on this thoroughfare. We can have anywhere between 150 and 400 movements a day; quite a few trucks coming up and down the street."

Mr Buxton was instrumental in organising a meeting for industry on Friday to discuss what collaborative efforts could be made to resolve the problem.

The EPA's pollution response unit was also in Bunting Road last week.

EPA senior manager Matt Vincent agreed a broad area could be impacted.

"Dust across Melbourne is known to travel a long way and, in fact, if you look at some of the cases dust can come [from] as far as the Mallee."

While the unsealed road is sporadically watered down, giant mounds of earth and rubble remain uncovered.

Mr Vincent said some industry practices were years and years old. "I don't think there's anywhere else like this in Victoria where there's such an accumulative impact from industry.

"I think each individual industry needs to sit down and think about what needs to be done."
