Quarry Consultative Committees

Ondit Quarry

Key matters discussed at the Ondit Quarry Consultative Committee meeting held via video conference on 16 February 2021:

  • Monitoring reports relating to groundwater, dust and blasting were discussed.
  • It was noted that one of the groundwater bores had not been monitored as it could not be located. Holcim has since addressed this. A PVC pipe at another monitoring bore requires fixing.
  • It was noted there was an exceedance of overpressure (118 instead of 115) on one particular blast, but that this is permitted (the current Work Authority allows exceedances of up to 5% in 1 in 10 blast instances. Holcim had reported the blast result immediately to Earth Resources and believe it was caused by high winds that day.
  • There was discussion about where future receptors should be for blast monitoring north of site now that the Ritchie residence is being relocated. Earth Resources noted that monitoring is only required where there is a sensitive receptor such as a house, and within 500m of the site.
  • It was noted that dust levels have exceeded the benchmark level a number of times late in 2020, which has been attributed to causes unrelated to the quarry. There have been no complaints related to dust caused by the quarry.
  • Holcim indicated they had recently lodged a planning permit application with Council for extension of the quarry extraction area to the north and north-east of the existing quarry (within the same site). An application has also been made to amend an older permit to allow blasting to occur closer to the road.
  • A draft Work Plan has been approved by Earth Resources after Holcim spent the majority of 2020 addressing technical issues requested of them. That process involved referral to relevant agencies who have signed off on the plan. Council officers are still assessing the application for future information that may be required. Public notice will be given to owners & occupiers within 1km of the proposal.
  • Council indicated it would be engaging a consultant to peer review the groundwater report submitted by the applicant and agreed to explore whether this consultant could meet interested land owners on site to discuss groundwater issues, particularly once it is known what objections have been received (if any) to the new application.
  • Council agreed to investigate concerns raised about the unsafe road condition of Warrion-Coragulac Road. It was noted that the speed limit was reduced to 80 km/hr 2 years ago but the road surface has not been fixed. 


Mooleric Road Quarry

Key matters discussed at the Mooleric Road Consultative Committee meeting held via video conference on 21 October 2020

  • The quarry operator confirmed that monthly water monitoring results are being provided to WMIS as required by the Groundwater Management Plan but WMIS is reluctant to publish them publicly.  Council will work with the operator to resolve this issue.
  • It was noted that the permit requires an annual report on groundwater monitoring to be prepared and discussed at Consultative Committee meetings.  The first report is due in 2021.
  • Duncan Barber has advised Council that he no longer will be a community representative on the Committee, prompting the need for a new process of seeking community nominations. Council will commence this process after the local government elections. It was discussed that back-up nominees would be sought to enable future vacancies to be filled without the need for a new process each time.
  • The quarry operator advised that quarry operations have commenced and the site is fully developed and trees planting complete.
  • There was discussion over expected truck volumes on Mooleric Road. It was noted that recent truck numbers had been low due to wet weather that has reduced demand for materials, but expect this to increase as the weather improves. 
  • The operator noted that whilst trucks visiting the quarry appeared to be following the 40 kph speed limit imposed on them, a high number of other trucks are travelling along Mooleric Road to areas north of the quarry at much faster speeds (not being obligated by the same speed restriction as quarry related traffic). 
  • It was confirmed there had been no complaints received and recorded in the on-site register in the period since the last meeting.
  • Next meeting is scheduled to be held on 23 March 2021
