Hanson preps EIS for Brandy Hill expansion

Increasing state government infrastructure spending has prompted a construction materials supplier to propose an expansion of its quarry, for which it will soon lodge an environmental impact statement.

Hanson Construction Materials has applied to expand its existing Brandy Hill quarry, located north of Sydney, to extract and process up to 1.5 million tonnes per annum (tpa) of hard rock material for 30 years.

The 561ha quarry has been in operation since 1983, supplying rhyodacite hard rock aggregates to the Hunter, Central Coast and Sydney regions.

According to the project’s preliminary environmental assessment (PEA), the quarry’s production typically averages approximately 620,000 tpa, with about 12 million tonnes of reserves still to be extracted.

A Hanson spokesperson told Quarry that expanding the operation would better position the company to meet the construction resource requirements essential for the region’s future growth and development.

“Demand in the Newcastle, Central Coast and Sydney markets is strong,” the spokesperson said. “With additional infrastructure spend from the New South Wales Government, [demand] will continue to remain this way for some time. The development [expansion project] will ensure Hanson is well placed to meet this need.”

In addition to the production increase, the project would include the construction of a new, 15,000m3 per annum concrete batch plant, and the acquisition of new ancillary plant, such as a mobile pugmill and pre-coat plant.

Hanson also proposes to receive about 20,000 tonnes of concrete washout waste from concrete batch plants in order to produce blended recycled aggregates and roadbase on-site.

Expansion advantages

The Hanson spokesperson pointed out that the project would benefit the local community. “The quarry provides employment for approximately 30 people as well as supplying the local [regions] with essential building materials. In addition, Hanson has been involved with a number of community-based projects in the local area with various sporting teams and schools,” he said.

The PEA also outlined the “significant advantages” the project offered compared to the establishment of a new quarry at an alternate location, stating that expanding the existing quarry would reduce the environmental costs associated with remediating another site and transporting product from a series of separate, more distant operations.

“The production of materials proximate to markets directly affects the cost to consumers, including councils and infrastructure providers, and overall infrastructure and development costs and affordability,” the document added.

The Hanson spokesperson said the company was currently consulting with the local community in relation to timing and progress, and that it planned to lodge an environmental impact statement in the coming months.
