The application sort approval for production levels of up to 120,000 cubic metres per annum, with specific qualifications as to when production levels would exceed 20,000 cubic metres per annum. Given the strategic location of the quarry and its unique product, the development described two modes of operation. When combined, the two types of production represented the 120,000 cubic metres annual limit sought by the applicant. The two operational modes for the activity described are ‐ 1. Normal Production – normal (extraction volume limited on a per annum basis to 20,000 cubic metres) extraction associated with minor works including those conducted by the proponent and for sale to customers. 2. Major Projects – those projects which require a large volume of material (maximum of 100,000 cubic metres of extraction per annum) over a short to medium term (weeks or several months) which have social and economic benefits to the island economy and infrastructure. The intensified quarry operation includes two activities defined within Schedule 2 of the Environmental Management and Pollution Control Act 1994 (Tas) (EMPCA) – ‘5. Extractive Industries. (a) Quarries: the extraction of any rock or gravel and producing 5 000 cubic metres or more of rock or gravel per year’ [ie. Maximum 120,000 cubic metres per annum]; and ‘6. Materials Handling. (a) Crushing, Grinding or Milling: processing (by crushing, grinding, milling or separating into different sizes by sieving, air elutriation or in any other manner) of … (ii) rock, ores or minerals at a rate in excess of 1 000 cubic metres per year’ [ie. Maximum 120,000 cubic metres per annum]. Level 2 Activities must be referred by the Planning Authority (in this case, Flinders Council) and to the Environment Protection Authority (the EPA), for assessment under EMPCA. Council advertised the application for a 28‐day period within which anyone could make a representation about the project. When the representation period closed, the Council forwarded all representations to the EPA. The Environment Protection Authority (EPA) received additional comments from referral agencies in relation to planning application DA 012/216 and supporting documentation including the document entitled Development Proposal and Environmental Management Plan, ‘The Gums’ Quarry, Palana Road, Whitemark, Flinders Island dated 9 October 2016 (DPEMP). Eleven public representations were received. These are identified by number only in Tables 1 and 2. Comments were also received from Flinders Council and several State Government agencies. A supplementary report to the DPEMP was requested by the EPA. Information required by the EPA is listed in Table 1. In addition, the EPA has encouraged the proponent to provide comment on the public and agency comments listed in Table 2. 4 The Gums Quarry, Palana Road – DPEMP Supplement TABLE 1: ADDITIONAL INFORMATION REQUIRED BY THE EPA BOARD Supplement Representation Comments and issues Additional information required No. No./ Agency Contends that the purpose of the Right of Way (ROW) on Confirm the access routes from Palana Road to the quarry site the neighbouring property was to access an internal block and provide the map grid coordinates of each access point to the 1 6 and that because this block now has independent access land to which the planning application relates, noting that these the ROW “has lost its intended use”.

It is also noted that Council have advised that the use of the existing access road, at least for some vehicle movements, is being considered. As discussed above confirmation of vehicle route usage is required. Submit a dust management plan which takes into account road routes on the land to which the planning application for the proposal relates. The plan should include: an assessment of the potential dust generated from the road It is noted that according to the DPEMP, at the proposed surfaces and from the quarry location to cause an environmental quarry operation peak intensity the number of loads nuisance at the nearest residence in other ownership.
