Operator Daracon plans to increase output from the quarry from 300,000 tonnes to 1.5 million tonnes a year.

Martins Creek Quarry Action Group has sent background notes and recommendations to all state election candidates contesting the seat of Maitland.

The briefing notes also outline concerns about the planned expansion of Brandy Hill Mine and have been sent to various candidates in the Upper Hunter and Port Stephens electorates.

The group wants the state government to force Daracon to transport most of its product from the quarry via rail and allow only 24 truck movements to and from the site each day.

It wants the output from the quarry limited to 300,000 tonnes per year and the site to be open only between 7am and 5pm weekdays, except public holidays.

The group said the expansion would impact about 7860 people.

Action group spokesman Darach Saunders said the plan was an overwhelming concern for thousands of people who lived near the quarry and along the common freight routes.

Quarry trucks commonly passed through Lorn, Bolwarra, Morpeth and Bolwarra Heights, he said, and would affect residential and commercial precincts in those towns.

Mr Saunders said there would be severe impacts to safety, amenity and property values if an application to allow the quarry to operate all day and night, every day of the week, was approved. 

“Feedback from residents we receive indicates community frustration regarding the ongoing apparent illegal intensification from Daracon’s Martins Creek facility and government inaction to ­regulate and police this free-for-all,” he said.

Daracon is preparing an environmental impact statement for the NSW Department of Planning, which will make a ruling on whether the company can go ahead with its increased operations.
