You may or may not have heard of Mangrove Mountain Landfill. It sits at the highest point of the Central Coast water catchment and threatens the quality of the community's water supply. Both Central Coast Council and the EPA admit this fact. The Landfill is located at the Mangrove Mountain Golf Course on the boundary between Gosford LGA and Wyong LGA. The threat comes from escaping leachate produced by the landfill that can seep into the underlying groundwater aquifer. This landfill has been getting bigger since 2001 and is currently 10X its approved size.

The landfill has lain idle since 2014, following action in the Land and Environment Court, although there is still the matter of 800,000 cubic metres of waste sitting there without an effective lining underneath to prevent the escape of toxic leachate into the groundwater.

Scientific study has demonstrated that almost half of the stream flow in Ourimbah Creek comes from this groundwater. Central Coast Council pumps out of Ourimbah Creek into Mardi Dam. Water in Mardi Dam is shared with Mangrove Creek Dam. These are the two potable water storage facilities for the entire Central Coast. And there lies the problem!

The Mountain Districts community has been engaged for over ten years, opposing this threat to the regional water supply. Presently the matter is in the Land and Environment Court, again. The landfill operator, Verde Terra Pty Ltd, applied to have its environment protection licence (EPL 11395), renewed on the 2 August 2018, to enable it to resume operations. The licence application was refused by the EPA on the 9 August 2018, and Verde Terra lodged an appeal against this decision in the Court on or around the 15 August 2018. If successful, this will authorise the importation of 1.318 million tonnes of new waste in addition to the existing vast waste mound, without submitting a new Development Application or Environmental Impact Statement

On behalf of the community, Mountain Districts Association vigorously opposes this application and calls on members of the general public to do the same by making a submission to the EPA.

Make a Submission

Verde Terra Pty Ltd’s application and supporting documents can be found on the EPA’s website at https://www.epa.nsw.gov.au/working-together/community-engagement/community-news/mangrove-mountain-landfill.

It is not necessary to read all of the documents. They are only those submitted by Verde Terra Pty Ltd to support its application with the EPA. In making a submission you need to ask yourself one question - "Do I want to risk my, my children's, my grandchildren's water supply being contaminated by toxic pollutants in the future when I have a chance to put a stop to it now?"

If your answer is NO, then send a Submission to the EPA saying so.

Submissions on the Application may be made to:

MML Submissions – Waste Branch, Environment Protection Authority, PO Box A290, Sydney South NSW 1232. 

The closing date for submissions is 20 December 2018.

Below are suggested reasons for opposing Verde Terra Pty Ltd’s application. We need your input. Please do not assume others will take on the responsibility. This may be your one and only chance to have a voice.

Key issue - please include:
I believe that Verde Terra must be required to submit a new DA and Environmental Assessment, not only for assessment by Central Coast Council, but also to be subject to public exhibition and comment.
Then any or all of those below:

  1. The purity of the water supply for the Central Coast is at risk from run-off and seepage of leachate into the creek system supplying Mardi and Mangrove dams.
  2. The NSW Environment Protection Authority (EPA) and Central Coast Council, both regulatory authorities, are united in opposing the renewal of the licence, for the stated reason of environmental safety.
  3. EPA Guidelines for Solid Waste Landfills would today prohibit the siting of this landfill at the head of a water catchment.
  4. For over a decade, the Community is on record as frequently opposing the size, nature and operation of the landfill.
  5. Stormwater and leachate management at the landfill has been and still is poorly managed, with potential for contamination of ground and surface water, and potable water off-site.
  6. The landfill presently holds 800,000 tonnes of waste, 10x that permitted by the 1998 development consent (DC). Without considering the DC or environmental safety, in 2014 the Land and Environment Court (LEC) approved a further 1.3 million tonnes of waste to be imported into four new cells (W, X, Y and Z) in Area B. Central Coast Council requires a new Environmental Impact Statement and Development Application for this major change. Verde Terra Pty Ltd has not submitted either.
  7. The present waste mound is over 85% unlined, allowing toxic leachate to enter the underlying Zone 4 Kulnura Mangrove Mountain aquifer and ground water.
  8. The EPA has not transferred important pollution control guidelines from its ‘EPA Guidelines for Solid Waste Management’ to this landfill’s licence, creating a loophole for the Operator to pollute without penalty.
  9. The current three stormwater ponds and leachate holding pond have been operating in an unlicensed area for 10 years, outside EPA’s jurisdiction, emphasising slack management of the site by all parties.
  10. Increase in truck traffic carrying waste in a rural community to an average of 55 truck movements/day over a 10 year period.
  11. A 6-7 million litre odoriferous leachate holding pond is planned for siting on the golf course near a gully leading to Stringybark Creek. It has the potential to contaminate both golf course and creek and drive away golfers.
  12. Dust, noise and smell will affect neighbouring Central Mangrove School, adjoining private properties and the Mangrove Mountain Memorial Club with its restaurant.
  13. Current EPA water testing is inadequate for detection of pollution of ground and surface water by the landfill, assurances of safety in a 2017 EPA Media Release notwithstanding.
  14. EPA oversight of the landfill has drawn extensive criticism for several years from the local Mountain Districts Community and from a broad base of Central Coast residents.
  15. The Community is in favour of a golf course, but it was purchased by the landfill owner in 2014 and is no longer owned by the Community, so its future is in doubt.
  16. The Community has been promised an 18-hole golf course for over 20 years, but has little confidence that delivery of the golf course will eventuate, or that it will be commercially viable.
  17. Verde Terra Pty Ltd, the licence holder, has no community consultative process and will not permit access to view its operations.
  18. The aquifer has been breached at the base of Cell W, without a licence to take water. This will also interfere with lining and longevity of this Cell.
  19. The Community and regulatory bodies such as the EPA and Central Coast Council have minimal or limited oversight of Verde Terra Pty Ltd’s activities on the landfill. The granting of a licence renewal will quite literally be a licence to pollute.
  20. An independent consultant appointed by the EPA with input from Mountain Districts Association, Alan Dyer, produced a report entitled ‘Technical, Environmental and Operational Review of Mangrove Mountain Landfill’ in May 2017, with 61 suggestions for improvement. This report has been omitted by Verde Terra Pty Ltd in its supporting documents.
  21. A NSW Parliamentary Committee into the Waste Industry, ‘Energy from Waste: Technology’ recommended an inquiry into the Mangrove Mountain Landfill in March 2018. The NSW Government declined, again, and so remains unaccountable.
  22. Sub-surface methane gas levels between 2012 and 2016 have been as high as 896,000 ppm, far higher than the 500 ppm permitted, with no acknowledgement or warning by the EPA or Verde Terra Pty Ltd. These levels indicate that putrescible waste has been landfilled, which is not permitted
