I thank the member for some notice of this question. On behalf of the Minister for the Environment I am happy to provide the following response - (1) The Environmental Protection Authority’s guidance 3 of 2005 on separation distances between industrial and sensitive land uses advises that a general buffer distance of between 500 and 1 000 metres should be maintained for mushroom farms that use on-site blended soils or compost, depending on the size of the facility. This is a general guidance and it is recognised that a lesser buffer may be acceptable in particular cases. The EPA’s 1997 preliminary guidelines for environment and planning are no longer current. (2) The advised general buffer distance for odour and noise pertains to mushroom farms using on-site blended soils or compost. (3) The EPA and the Department of Environment considered the adequacy of buffer distances to nearby residential land uses when assessing development proposals and licence applications submitted to it under the Environmental Protection Act 1986. The EPA and the Department of Environment have also provided advice on general buffer distances to the Western Australian Planning Commission and local authorities that are responsible for planning and development decisions. (4)-(5) No. (6)-(7) No. These matters should be referred to the Minister for Health.
