Hon. Kate Doust questions the Minister for Housing and Works regarding the Water Corporation's compliance with odour reduction commitments at the Woodman Point Wastewater Treatment Plant (WPTP) and its impact on nearby residents. The Minister acknowledges shortcomings in prior modelling but highlights significant odour reduction efforts and ongoing programs.

(1) Is the Minister aware of the Commitment (P2) given by the Water Corporation on page 92 of its Environmental Assessment and Management Plan prepared by Sinclair Knight Merz in January 1999, that formed part of the environmental assessment for the WPTP 160 ML upgrade and expansion?
(2) If the answer to (1) is yes, the Minister would also be aware that the said environmental assessment plan was based on odour modelling undertaken by CH2MHill in January 1999, that indicated a five odour unit (OU) would reach no further than the eastern edge of Lake Coogee after the 160 ML upgrade. Commitment (P2) in the Plan also pledges the Water Corporation to ‘rectify significant odour issues to the satisfaction of the DEP, should monitoring subsequently reveal exceedances of the 5OU at odour sensitive premises’. Can the Minister explain why the Water Corporation has not complied with these commitments and why the Water Corporation is in fact telling residents affected by WPTP odours that it cannot reduce odours to the 5OU boundaries set out in the Environmental Plan?
(3) Can the Minister explain what technical and operational changes would be needed to overcome the odours from the WPTP currently affecting residents of Munster and Coogee and ensure the Water Corporation meets the commitments referred to in (2)?
(4) Can the Minister provide cost estimates for the technical and operational changes needed to overcome the odours from the WPTP currently affecting residents of Munster and Coogee and ensure the Water Corporation meets the commitments referred to in (2)?
(5) Can the Minister explain why the Water Corporation believes it can make technical changes to the WPTP so that odours do not impact on residents to the north of the plant, but these changes would not lead to the reduction in odours for those residents living east of the plant?
(6) Is the Minister aware of the significant investments and changes that local Munster companies, Watsonia and Cockburn Cement, have made in reducing odours from their plants?
(7) Is the Minister concerned that the Water Corporation’s failure to address its odours in line with its own commitments sends a very bad message to the private sector and can be seen as the Government adopting double standards?
(8) Is the Minister aware of the activities by the Water Corporation in reducing odours from the Subiaco Treatment Plant?
(9) If so, does he support the Water Corporation instigating similar action at the WPTP to the same extent?
(10) Is the Minister aware of any policy or objective that would encourage or support the Water Corporation seeking a determination from the Western Australian Planning Commission on a restrictive planning buffer zone over existing residences around the WPTP regardless of outcomes from odour modelling studies?
(11) If yes, does the Minister support such a policy or objective?

(2) The odour modelling on which the Corporation's commitment was based has proven to be optimistic and re-modelling in 2003 has shown that Commitment (P2) has not been met. In acknowledging this, the Corporation advises that the 1999 modelling for Woodman Point Wastewater Treatment Plant (WWTP) relied on predicted odour emissions using experience from other WWTPs and a relatively limited (compared to today) scientific understanding of odour emissions. The science has since developed, leading to more accurate odour emission measurement and dispersion modelling. Consequently, the actual odour emissions at Woodman Point have proven to be different to those predicted. The Corporation has not said that the odours cannot be reduced to the 5 OU boundary, rather the Corporation has said that this target can not be met by the WWTP, as it is currently designed. It should be noted, however, that the odour control measures put in place as part of the $150 million upgrade have resulted in an overall reduction (~48%) on pre-upgrade odours and this is despite an overall increase in the plant's capacity. (3) The "Report on Odour Impacts for the Woodman Point Wastewater Treatment Plant - December 2003" gave preliminary recommendations as to what technical and operational changes might be required to reduce current odour levels, but not necessarily to meet Commitment (P2). The Corporation has since initiated an Odour Reduction Program of which the first phase is to determine in more detail the technical requirements of further odour reduction and the odour buffer targets that might possibly be achieved. The outcomes of this process will be submitted to the Environment Protection Authority via a Strategic Environmental Review process early in 2005 and will subsequently be open to a public consultation process. (4) At this early stage of the Corporation's new Odour Reduction Program, firm details on what it would cost to reduce the buffer back to the east side of Lake Coogee are not available but it is expected to be in the many tens of millions of dollars (possibly up to $100 million), if, at all possible. (5) The Corporation's position is based on information from an independent odour specialist who advises that due to the nature of prevailing winds, local topography and the nature of odour dispersion over rough ground verses a smooth lake mean that a reduction in odour emissions from the WWTP can provide such gains to the north, but less so to the east. (6) Yes. In relation to Cockburn Cement, a one kilometre buffer has been identified within the review of the EPA's Environmental Protection (Kwinana) (Atmospheric Wastes) Policy Approval Order 1999. Further, this 1 kilometre buffer is also recognised by the City of Cockburn Town Planning Scheme No. 3. It should also be noted that Lake Coogee represents a significant odour source that is not actively managed at present and, based on independent advice to the Corporation, a 250 metre buffer around the lake would be needed to minimise the impact of these odours to meet current community odour expectations. This information has been forwarded to the DoE for their assessment. (7) The Corporation has demonstrated a significant commitment to reducing odours in the Coogee-Munster-Henderson area. The Environmental Enhancement Project at Woodman Point included a $30 million investment in odour control comprising the relocation of the Munster Sewage Pump Station ($20M), the covering and sealing of inlet and primary treatment works ($5M) and the provision of chemical and biological odour scrubbers ($5M). These odour control works reduced the odour from the WWTP by almost half despite the increased hydraulic capacity (33%) and nutrient reduction capacity (90%). (8) Yes. (9) The Corporation has instigated a new Odour Reduction Program at the Woodman Point WWTP. (10) The existing odour buffer for the Woodman Point WWTP extends 1,000 metres to the north and 750 metres to the east, west and south of the plant. It is currently defined by land zonings that allow land uses that are consistent with the operation of a WWTP. In January 1997, the land within the existing buffer to the east of the plant was rezoned from Rural to Urban Deferred with a note from the then minister for Planning that it should not be considered suitable for future residential development. The land use prior to this was primarily market gardening. In March 2004, the Minister for the Environment, at the request of the Corporation, sought advice from the EPA with respect to the technical accuracy of the Corporation's odour sampling and modelling and the nature and extent of the buffer required for the plant. The Corporation recommended that the existing buffer remain in place. Recently, the EPA has requested that the Corporation provide further information by way of a Strategic Environmental Review document, detailing an overview of the Corporation's plan and objectives in relation to the odour buffer, including a proposed Odour Reduction Program in order that it may undertake public consultation on the matter.
