Quarry plans to double output
quarry operator wants permission to double its yearly output to four million tonnes and increase the number of trucks on local roads.
Karreman Quarries says it needs to boost output at the quarry on West Mount Cotton Road because of “unprecedented demand” for aggregates and road base materials in South East Queensland.
Existing Redland Shire Council conditions allow an output of about two million tonnes each year from the quarry, which was established in the 1950s.
About 260 trucks are allowed to travel to and from the site daily, although the conditions allow the number of trucks to go as high as 312 in periods of high demand.
The quarry operator has applied to double output, but a traffic report argues this does not mean twice as many trucks would be required – partly because larger trucks would be used if more material was being transported.
