The site along Greghamstown Road, north of the Nestle Purina Petcare factory, could have up to 250,000 tonnes of earth mined a year for road construction materials, with crushing and screening to occur on-site.

The developer of the site Ben Volkofsky said that although approval had been given, it may be some time before work commences on the site.

"It's all a bit up in the air at the moment as to how we go about it," he said. "We have to get it right."

Mr Volkofsky said that the project would develop over time.

"It may not be that busy for a while as it's like any business that has to grow and develop," he said.

Part of the delay for Mr Volkofsky is complying to conditions set down by Blayney Shire Council and the Environmental Protection Agency.

"I'd like to think that we can get started within six months but there is a lot of work to do to comply with council's and the EPA's requirements," he said.

Part of those conditions is the construction of an amenity bund to screen the site and the planting of native trees in the bund within 12 months of the granting of consent.

Councillor Bruce Reynolds said that a number of councillors had put together extra conditions on top of those developed by council staff, and he was very concerned about the nearby residents.

"We're disappointed that it has been given approval without the tighter conditions that councillors put forward to the Joint Regional Planning Panel," he said.

"I hope that the company communicates and talks with the residents and makes sure that they're fully aware of the hotline as to when they're going to do blasting and other activities."
