McCamey's Monster Iron Ore Mining Proposal

Summary:

Hancock Mining Ltd proposes to mine high grade iron ore from a scree and erosion fan located south of McCamey's Monster Hill.

The initial output in the first year will be 3 million tonnes which will increase to 5 million tonnes in the second year. The total tonnage over the life time of the project is 34.5 million tonnes. The processing plant will consist of a series of screens to separate the ore from the waste. The product ore will be transported to Port Hedland via a haul road to the Mt Newman to Port Hedland railway and then by rail.

The mine will employ approximately 117 people at full production. These will be housed at the existing camp until houses are constructed in Newman.

The Environmental Protection Authority determined that the project's potential for environmental impact required it to be formally assessed under Part IV of the Environmental Protection Act 1986. The Authority decided that a Notice of Intent was required to assess the proposal.

Upon assessment of the Notice of Intent, the Authority considered that the proposal is environmentally acceptable but has made recommendations relating to rehabilitation and seeking further referral of any expanded operations proposed.

Draft Environmental Protection Policy for the control of sulphur dioxide in the air environment of the Kalgoorlie-Boulder residential areas

Summary:

Since 1980, gold mining and processing industries in the Kalgoorlie-Boulder area have been operating pyrite roasters to extract gold from sulphide-based ores. These roasters oxidise the sulphide ore, producing large amounts of sulphur dioxide gas which is released from chimneys into the surrounding air. Sulphur dioxide is also released from the nickel smelter situated south of the Kalgoorlie-Boulder townships.

In 1982 a Task Force was established to investigate the extent of sulphur dioxide pollution and to make recommendations to the then Air Pollution Control Council on appropriate measures for controlling this pollution. The Task Force submitted its final report to the Minister for Environment in September 1987, and the report has subsequently been released to the public. The report provides a detailed discussion on the historical and technical aspects of the sulphur dioxide problem in the Kalgoorlie-Boulder area; such information is not repeated here.

In order to address the sulphur dioxide pollution problem and provide an enforceable control mechanism which is appropriate in the context of community dependence on mineral processing for its economic existence, the Environmental Protection Authority has proceeded to develop a draft environmental protection policy entitled "DRAFT ENVIRONMENTAL PROTECTION POLICY FOR THE CONTROL OF SULPHUR DIOXIDE IN THE AIR ENVIRONMENT OF THE KALGOORLIE-BOULDER RESIDENTIAL AREAS". The initial draft policy was released for public review on 14 August 1987 with an invitation to interested persons and organisations to submit comments to the Authority by 18 September 1987. A public meeting attended by the Authority Chairman was held in Kalgoorlie on 10 September 1987, for the purpose of informing interested persons about the draft policy and providing them an opportunity to put forward their views. Subsequent to the close of the period for public comments, the draft policy has been reviewed and revised in the light of comment received.

This report accompanies the submission of the draft policy to the Minister for Environment in accordance with Section 28 of the Environmental Protection Act 1986.

Boddington Gold Mine Project - enhancement of facilities

Summary:

Worsley Alumina Pty Ltd has submitted a proposal to upgrade the existing Boddington Gold Mine facilities by increasing the maximum daily process plant throughput from 8 000 tonnes to 12 000 tonnes.

Ore would continue to be mined from the same orebody currently being mined. It is therefore expected that the proposed increases in the rate of production would shorten the overall project life from fifteen to possibly ten years.

The plant facilities required for the upgrading would be an additional crusher, a ball or semi-autogenous grinding mill, additional classification cyclones and a leach tank. Residue transfer pumps would also require upgrading. It is proposed that other areas of the plant would remain the same, and no additional clearing beyond the existing plant site perimeter would be required.

To provide adequate process water for the upgraded plant, it is proposed to enhance the water supply system by upgrading the pump station on the Hotham River, and to duplicate the delivery pipeline to the Water Supply Reservoir.

It is also proposed to increase the capacity of the Water Supply Reservoir by raising the maximum surface water level by 0.9 m. This would be achieved by installing a deflatable rubber dam on the crest of the existing spill way. No further clearing around the reservoir would be required.

Proposed amendment to Metropolitan Region Scheme - Rezoning from Rural to Urban and Urban deferred, Stirling Crescent Hazelmere

Summary:

Swan Shire Council has submitted an overall planning strategy for the Hazelmere area to the State Planning Commission (SPC) and has requested the Commission's consideration to amending the Metropolitan Region Scheme (MRS) to introduce Urban and Urban Deferred zoning and an Important Regional Road reserve into the area.

The SPC referred the proposed MRS amendment to the Environmental Protection Authority (EPA) requesting comments and/or recommendations on Council's submission. The EPA determined that the proposal should be assessed under Part IV of the Environmental Protection Act 1986 and that the level of assessment would be Notice of Intent (NOI). The potential environmental impacts of the proposed amendment have been assessed from information provided in the NOI.

The Environmental Protection Authority has concluded that the environmental acceptability of the proposal is constrained by several environmental factors. In order for the proposal to be considered environmentally acceptable, these environmental factors would require managing. The Authority has recommended accordingly.

Amendment to Prestige Brickworks Proposal to redevelop Midland Abattoir site, Midland

Summary:

In its first Assessment Report on this proposed brickworks (EPA Bulletin 289) the EPA indicated that the potential for damage to vegetation resulting from fluoride emissions from the brickworks was the main environmental issue. The Authority acknowledged that there exists a potential for minor injury to vegetation from fluoride fallout from the brickworks. The same general conclusion on fluoride impacts is relevant to the proposal described in the Notice of Intent.

The relocation of the clay stockpile area has the potential to impact on the Helena River floodplain. The stockpile area is closer to existing and proposed residential development in Hazelmere, but the proposed configuration of the stockpile should ensure that noise levels emanating from the operation of loading equipment will be within acceptable limits.

The conclusions and recommendations in EPA Bulletin 289 have been reiterated for the sake of completeness.

Bow River Alluvial Diamond Project

Summary:

Freeport Bow River Properties Limited has submitted a proposal to mine alluvial diamonds in the Bow River area of Western Australia.

The proposal involves the establishment of a plant to process riverine gravel. The fine waste material will be disposed of in a tailing dam and the coarse waste material dumped near the processing plant. The diamondiferous material will be concentrated in a Heavy Medium Separater and then sorted using an x-ray diamond sorter. The plant will process 4 000 tonne per day.

The orebody covers approximately 500 ha and has an average depth of 2 m. The deposit will be mined progressively allowing rehabilitation to be ongoing during the mining operation. All topsoils and black soils will be stockpiled for rehabilitation or placed directly over mined out areas. The expected lifetime of the project is seven years. It will employ approximately 80 people on-site and 2 or 3 in Kununurra.

On completion of the project all plant equipment and camp facilities would be removed and the areas rehabilitated.

The Authority determined that potential for environmental impact would not require it to be formally accessed under Part IV of the Environmental Protection Act 1986. Accordingly this report is not a formal assessment report of the Environmental Protection Authority and as such there are no appeal rights on the report and recommendations.

Proposal to Change Mining Methods Of Eneabba South Operation from Dry Mining to Dredging

Summary:

Associated Minerals Consolidated Limited has submitted a proposal to change mining methods of the Eneabba south operation from dry mining to dredging.

This would involve the establishment of a dredge pond in existing mining pits from which a suction cutter dredge would progress along a prescribed mining path followed by a floating wet concentrator plant.

Tailings would be stacked behind the operations allowing rehabilitation of mined out areas to be carried out progressively as the dredge operation proceeds.

Rehabilitation would involve re-establishment of native plant species over disturbed areas in the same manner that is applied to existing dry mining operations.

In initially considering the Company's proposal the Authority determined that the potential for environmental impact would be required to be formally assessed under Part IV of the Environmental Protection Act, 1986. Upon assessment of the Notice of Intent that was prepared by the Company it was determined by the Authority that the change from dry mining methods to dredging at the south Eneabba m1n1ng operations is environmentally acceptable

Limesand Extraction - Lancelin

Summary:

In accordance with the conditions of the mining leases, a mining plan was submitted to the Department of Mines by Endeavour Resources Limited to continue mining operations in the Lancelin dunes. These plans were subsequently referred to the Environmental Protection Authority for assessment with respect to the environmental aspects of the proposal.

This proposal discussed various stages of development through the perceived life of the project: initially removing sand from low lying dunes west of the main dune system where previous operations were carried out. This would have required transport of material through the Lancelin Townsite.

A modified proposal has since been submitted to the Authority proposing to re-locate the sand mining operations to an area in the vicinity of the Shire's rubbish tip and sand pit. Access to the site will be gained via the existing tip road, south of the townsite. This would remove the need for trucks to pass through the Lancelin townsite.

In the Company's revised proposal it is estimated that approximately 1 000 tonnes of sand will be mined in 1988 with tonnages likely to increase by 1 000 tonnes each year to a maximum extraction rate of about 30 000 tonnes per year. This would result in around 15 000 tonnes of sand being removed from an area of about 0.3 hectares over the next five years.

Environmental and health performance of waste to energy technologies

Summary:

Advice of the Environmental Protection Authority to the Minister for Environment under Section 16(e) of the Environmental Protection Act 1986

On 16 November 2011, the Minister for Environment wrote to the Chairman of the Environmental Protection Authority (EPA) and the Chairman of the Waste Authority, requesting that the two Authorities investigate the environmental and health performance of waste to energy technologies internationally.

This request sought information on:

  • legislation for the establishment and operation of waste to energy facilities, focussed on emissions, in jurisdictions where these facilities currently exist;
  • current emissions from established and operating best practice facilities; and
  • current and historical level of compliance of these facilities.

The Minister requested that the information gathered be from full-scale, commercial plants that process municipal solid waste (MSW) and from a variety of technology types.

To assist with this investigation, WSP Environment and Energy Ltd were engaged to undertake a technical review of waste to energy plants around the world. These technical reports are attached. The reports provide detailed information to address the issues identified by the Minister for Environment. This advice from the EPA and Waste Authority draws on the technical advice to make recommendations that are relevant to the Western Australian situation.
