QuestionView source ↗

I refer to the
Environmental Protection Act 1986
licence dated June 13 2005 addressed to the Manager, Kanowna Belle Gold Mines -
(1) Is it correct that condition A6 states ‘The Licensee shall ensure that dust extraction and filtration equipment is installed and maintained so as to prevent emission of visible dust from the arsenic waste and dolocrete receival hoppers’?
(2) If no to (1), will the Minister quote the specific text of the condition?
(3) Can the Minister explain what is the specific purpose of the Department issuing and imposing licence conditions for any premises under the
Environmental Protection Act 1986
?
(4) If no to (3), why not?
(5) Can the Minister explain why does the licensee have to install dust extraction and filtration equipment so as to prevent emissions of visible dust from both the arsenic waste and dolocrete receival hoppers?
(6) If no to (5), why not?
(7) Can the Minister state why the licensee has to ensure that exhaust gases from the roaster are ducted through an electrostatic precipitator and fabric filter prior to discharge to the atmosphere through a chimneystack with a minimum height of 120 metres above ground level?
(8) If no to (7), why not?
(9) Can the Minister explain why the licensee is not permitted to burn waste oil, except for fire training purposes?
(10) Is it correct that condition W1(a) states ‘The Licensee shall store environmentally hazardous chemicals (where the total volume of each substance stored on the premises exceeds 250 litres) within low permeability (10-9 metres per second or less) compounds(s) designed to contain not less than 110% of the volume of the largest storage vessel or inter-connected system, and at least 25% of the total volume of substances stored in the compound’?
(11) If no to (10), will the Minister quote the specific text of the condition?
(12) Can the Minister explain what is the Department seeking to protect under the
Environmental Protection Act 1986
in requiring the licensee to store environmentally hazardous chemicals within low permeability 10-9 metres per second or less compounds, given that even with these compounds the chemicals can be expected to still seep into the soil and groundwater which is hypersaline and can be argued as having no beneficial use except for mineral processing?
(13) If no to (12), why not?

The Minister for the Environment; Science has provided the following response: (1) Yes. (2) Not applicable. (3) The Department of Environment (DoE) needs to issue works approvals and licenses subject to Section 62 of the Environmental Protection Act 1986 . In particular Section 62(1) states "A works approval or licence may be granted subject to such conditions as the CEO considers to be necessary or convenient for the purposes of this Act relating to the prevention, control, abatement or mitigation of pollution or environmental harm" (4) Not applicable. (5) The DoE considered that the installation and maintenance of dust filtration systems is a practical measure to minimise the impact of visible dust on the environmental values of the area. (6) Not applicable. (7) The DoE considers these a practical measure to minimise the impact of particulate matter in the exhaust gases from impacting on the environmental values in the area. (8) Not applicable. (9) An assessment has not been made on the suitability of this site to burn waste oil. The condition the Honourable member is referring to enables Kanowna Belle to undertaken fire training with waste oil. Should Kanowna Belle desire to expand the burning of waste oil an assessment would need to be made on its suitability. (10) Yes. (11) Not applicable. (12) The DoE considers bunding of environmentally hazardous chemicals a practical measure to minimise the impact on environmental values of the area. In general without a bund spills will occur onto the land surface and may come in direct contact with flora and fauna. However, the DoE is currently reviewing the appropriateness of this generic condition. Many environmentally hazardous chemicals are adequately covered by the Department of Consumer and Employment Protection through the Explosives & Dangerous Goods (Dangerous Goods Handling & Storage) Regulations 1992 and therefore should not be double regulated. This consideration will need to be made on a site-by-site basis. The DoE is undertaking this review as part of a general licence reform program, which is the implementation of the recommendations of the Welker Review of 2003. This premise is yet to be considered in light of that program. With approximately 850 licensed premises in the State this review will take some time to complete. In the Goldfields area, the Kanowna Belle license is likely to be reviewed in late 2006. (13) Not applicable
