Site Original History
- 1983 Limestone quarry in what is now Reserve 24198 dug to 6m depth on North side of Tim’s Thicket Rd.
- 1992 Analysis of Tim’s Thicket for waste site, on south side of Tim’s Thicket Rd, due to impending closure of Caddadup Reserve (now under Cut Golf course), due to creation of Dawesville Cut, but land is reserved for “camping & recreation”.
- May 1994 Land swap with CALM proposed to create waste site on north side of Tim’s Thicket Rd.
- Sep 1994 COM meeting where concerned residents point out that maps from Urban Geology Series maps from mines department state Tamala limestone is “undesirable land use” for septage disposal. (COM subsequently agreed to line the ponds which were then broken during sludge removal and which seeped through the limestone in 2003).
- May 1995 Land swap enacted creating Waste Management & Septage Disposal Site for COM Reserve 43301 with remaining land (Reserve 24198) set aside by Minister for “Camping & Recreation” to be upgraded to “Conservation & Passive Recreation” as per Bulletin 751 , Determination 375 and Consultative Environmental Review (p14). COM has failed to file the paperwork to change the Reserve usage as agreed in 1994. See reserve map.
Inert Landfill – Category 63 Class 1 Inert Landfill & Category 13 Crushing of building material
- 1995 L6860/1995/08 Licence granted for Category 63 – Class 1 inert landfill as per EPA Bulletin 470 1994. which specifically states:
“the word dry is used to clearly indicate that no liquids such as oils, acids, sewage or sludges should be disposed of at a dry infill site”, further it states; “chemical containers, paper and cardboard waste should not be dumped” .
- 1995 -1998 Inappropriate waste accepted as inert fill and dumped in old limestone quarry in reserve 24198 specifically set aside for camping and recreation, includes old fridges, tyres, cardboard, Asbestos. (See Photos)
- Sep 1997 Complaints made with photographic evidence of illegal waste acceptance to COM and DER
– Site waste not removed but immediately covered over with soil.
– DEP acknowledged receipt of letter & will investigate and advise, however no investigation carried out as site had already been covered over with soil.
- 2010 Aerial photos show stockpiling of concrete crushing material from 2010, in breach of the existing inert landfill licence.
- Jun 2014 Photos of further tip site breaches, this time in Reserve 43301 (COM Waste Site), emailed to DER. (See Photos)
- Jun 2015 DER issue new licence, removing class 61 Liquid Waste and insert improvement conditions for inert fill site class 63. (Awaiting outcome of FOI request to DER to confirm reasons for these improvement conditions.)
- Jul 2016 License L6860/1995/11 amended to approve crushing of building material on TT site, citing a number of regulations to be followed.
- Feb 2017 Complaint to COM from William St resident regarding 6am start and level of noise from equipment reverse beepers and noise of trucks dumping lorry loads of building materials for crushing. COM call Cleanaway and remind them not to start work prior to 7am.
- Aug 2017 DWER letter requesting submissions regarding Category 63 & 13 licences from 24 respondents of Septage Upgrade proposal.
Transfer Station – Category 62 Solid Waste Transfer
- Jun 2012 Council informed of additional funding of $300K raised from Waste Authority Regional Funding Program for Local Government Authorities 2011-2016 for Regional Transfer Station, with expiry of June 2016. No public/residential notification or request for comment on this proposal.
- 20 Aug 2013 Council adopts outline of intent Report 4 Tims Thicket Transfer & recycling centre G16/8/13T
- 21 Aug 2013 “Green light for Tims Thicket Tip” article in Mandurah Mail, however not yet approved by council and no license from DER.
- 27 Aug 2013 Council approves Report 8 for waste exchange at TT.
- 12 Sep 2014 COM applies to EPA for Transfer Station stating public consultation has taken place, that the proposal will not result in substantial transport of goods, and does not have a copy of the Minister’s determination 375 attached.
- 14 Oct 2014 EPA rule no assessment required.
- 17 Dec 2015 License for Category 62 transfer waste approved via Works Approval W5779/2014/1 with expiry date of 20/12/16 however license approval too late for Waste Authority Regional Funding Program funding allocation so Transfer Station on hold until new funding available.
- Aug 2017 NOTE – DWER letter requesting submissions regarding all licences from 24 respondents but excludes review of this license Category which we believe was erroneously granted due to lack of public consultation and the omission of the Minister’s determination meaning that the decision maker was not properly informed. This matter has been referred directly to the Minister of the Environment.
Liquid Waste – Category 61 Liquid Waste Facility
- Sep 1994 COM meeting where concerned residents point out that maps from Urban Geology Series maps from mines department state Tamala limestone is an undesirable base for septage disposal. (COM subsequently agreed to line the ponds which were then broken during sludge removal which seeped through the Tamala limestone in 2003.)
- 1995 – 1997 Septage facility installed along with bores MB1,2,3,4&5.
- 1997 – 2014 Ponds accepting liquid waste.
- Dec 2003 Monitoring Bore 4 (MB4) shows considerable increase in Nitrates. Note coincides with 7 year pond sludge removal which local resident believes caused a break in liner.
- Mar 2005 MB6, 7, 8, 9 water monitoring bores installed.
- Jan 2012 COM 2011 Annual report shows graph data for bores 1 – 5 only and shows large seepage loss.
- Jun 2013 Council approves closure of septage facility due to under use, scheduled to come into effect on 1st October 13.
- Oct 2013 Despite Council resolution in June the septage facility remains open.
- Nov 2013 Recreational water monitoring for TT & Melros beach suspended as per COM Recreational Water Monitoring Program, Health Services Report 2010 – 2014 (p12) which states: “Following a review of the sites in November 2013, it was decided that some of the sites would be removed from the list of designated sites. These sites were either used so infrequently or very unlikely to be affected by faecal contamination or dangerous to access for sampling.” But then on page 16 states: “Melros Beach (Site category: User Level – Low) Appendix 2 shows that 6% of the samples (or 1 in 18 samples) collected at Melros Beach exceeded the maximum recommended number of enterococci organisms.” It goes on to state “Subsequent results have been within the guidelines” Dates not available for these tests so it is unknown whether the subsequent readings were taken in summer, or in winter when they can be affected by adverse sea conditions. In addition Tim’s Thicket shows a persistent median reading of above zero.
- Dec 2013 Council votes to reopen Septage facility, but don’t appear to have been informed of the water monitoring breaches that have already occurred to date in Nov 2008/2010/2011/May 2013 – see entry Jul 2015.
- Jan 2014 Significant septage input, shown in quarterly Oct – Dec Regional Rivers report, shows input to TT site greater than all septage taken in previous two years. This increase coincides with DER investigation and resultant closure of Oakwood site for serious breaches of conditions by Bio-Organics.
- Apr 2014 Request for confirmation that water monitoring is compliant and for test results via MP Kim Hames with minimal/obfuscated responses. 2012 report shows increased nutrient levels for bores 2, 3, 4 & 5 from 2003 onwards, and breaches from 2008 onwards. Request to DER to investigate.
- May 2014 COM Council asked questions on notice regarding water quality with response that there “no breaches have occurred” from Director of Infrastructure. Additional questions confirmed that the proposal had not been put to MEAG (Mandurah Environmental Advisory Group) “as the proposal didn’t require planning approval”.
- Oct 2014 COM’s request to increase allowance beyond licensed capacity is denied by DER.
- Dec 2014 DER confirms investigation still underway but COM has agreed to cease use. DER requires pond liner conditions to be checked. Ponds fail and DER withdraws licence for past and ongoing breaches.

- Jul 2015 Council given a briefing report and a presentation by TALIS of Tim’s Thicket and are advised of water monitoring breaches from 2008 onwards, and vote to proceed with upgrade.
- Jul 2016 COM Septage site upgrade outline plan passed by Council at Jul 26 meeting. This outline plan makes no mention of the fact that the spray field is located over a previous tip site, or that the spray field location is on land set aside by ministerial directive for public use of camping & recreation.
- Concerns raised regarding outline plan in assessment document.
- Sep 2016 Question raised by councillor regarding spray field location at Sep 13 meeting.
