Quarry Consultative Committees

Ondit Quarry

Key matters discussed at the Ondit Quarry Consultative Committee meeting held via Teams video conference on 15 February 2022:

  • The 6 monthly groundwater monitoring results indicate that despite the quarry getting closer to the McCarthy boundary, the report indicates no adverse impacts on groundwater levels at current time.
  • Concern was expressed by one of the community representatives about what action would be taken if groundwater levels to adjoining properties were affected in the future.  It was indicated that such impacts had been considered at the Council planning permit and Earth Resources Work Plan approval stages, and found not to be significant.  Approvals had been granted on that basis.  It was indicated however that trigger levels for ground water had been put in place to ensure that if water levels dropped below these points, Holcim would need to provide technical assessments of the impact and make good water supplies for the affected properties.
  • Southern Rural Water confirmed that it has the powers at any time when water levels are adversely affected to an adjoining land holder as a result of the quarry operations, to either request the quarry to cease operations or supply water to that land owner. Holcim agreed it would assist land owners in these circumstances as required to ensure water supplies were available.
  • The blast monitoring report indicated blast overpressure exceedance of the 115dbA threshold on 13 October 2021, although It didn’t exceed the 120dbA limit, and as it was the only exceedance in a 12 month period, was permissible.  A consultant was engaged by Holcim to investigate the exceedance, with video footage showing no flyrock at the blast area. Earth Resources are satisfied there is no further action required as a result of this investigation. No complaints had been recorded.
  • Dust monitoring identified two exceedances on 30 November and 17 December 2021 however it is believed that this was caused by dust from off the property, and not from the quarry operations.
  • Holcim has indicated spraying of weeds was undertaken late in 2021 as normally occurs at that time of year.
  • Council indicated a Planning Permit had been issued in September 2021 for the quarry expansion within the site as no appeals had been lodged against the Council’s decision to approve the application. A Work Plan was then issued by Earth Resources.  Council is currently assessing management plans required to be endorsed under the permit, and finalising a S173 agreement related to future management of the Corangamite Water Skink.
  • Holcim advised it has been liaising with the agencies concerning preparation of a new planning application for the land north of Ondit Warrion Road (number 170). It is referred to as the Northern Development Area (NDA). It also requires a new Work Authority. Holcim will be submitting a draft Work Plan to Earth Resources over the coming few months. It could be a 2 year process before all relevant permits/consents have been granted before quarrying in the NDA could occur.
  • Next Meeting scheduled to be held 16 August 2022


Mooleric Road Quarry

Key matters discussed at the Mooleric Road Consultative Committee meeting held via Teams 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
