Newman Quarrying has applied to expand its operations at Sly’s Quarry, northeast of Grafton.
The proposed expansion would see the expansion of the sandstone quarry pit by 11.1 hectares, increasing the maximum extraction rate of sandstone to 500,000 tonnes per year.
Newman says the primary purpose of the quarry would be to supply a portion of the substantial quantity of quarry materials required for current and proposed Pacific Highway works, and for supply to local councils and contractors.
The Environmental Impact Statement is on display on the Department of Planning site, and the public has until June 17 to make a submission.
Newman said the life of the operation would be around 30 years depending on the timing of Government funding for the Pacific Highway upgrade projects and the quantity of materials needed to satisfy that upgrade.
Currently there are three employees at the existing quarry. If approved, the quarry is anticipated to require a further five full time employees during periods of maximum extraction.
Haulage of material would also provide employment for truck drivers. Haulage trucks would be engaged and operated by contractors external to the quarry operations
Additional off site employment would also be generated in the maintenance and support services for equipment and machinery.
Newman said model results indicate that noise levels generated from quarry operations are predicted to comply with the Industrial Noise Policy daytime noise criterion at all receivers.
While the predicted growth in traffic due to quarry operations during peak daily production is expected to comply with the Road Noise Policy criteria.
The company also noted that during the field survey and Aboriginal community consultation process, no Aboriginal objects or Aboriginal places were identified and the site was characterised as highly disturbed.
