AnswerView source ↗
I thank the member for some notice of this question. The Minister for the Environment has provided a fairly lengthy response. I seek leave to have it incorporated in Hansard . Leave granted. The following material was incorporated - (1) The air inside the Northbridge Tunnel is continuously monitored by Baulderstone Clough Joint Venture (BCJV), the tunnel builder and contract operator, for Main Roads Western Australia, for the purpose of controlling the tunnel ventilation system. (2-3) The Northbridge Tunnel project was only subject to an informal assessment by the Environmental Protection Authority. This level of assessment was subject to appeal to the former Minister for the Environment. However, the former Minister for the Environment did not upgrade the level of assessment on appeal and hence there was no ability to place Ministerial Conditions on the project, such as publishing of monitoring data, in the final approval. Actual monitoring data collected by BCJV is recorded by the Tunnel Control & Management System, where it is retained for a minimum of one month. In addition, any breaches of air quality standards are immediately reported to Main Roads Western Australia. However, to date there have been none recorded. (4) No. (5) Not applicable. (6) The potential impacts of emissions from the stacks were assessed via modelling during the environmental approval phase of Tunnel development. The modelling indicated that impacts from emissions were within acceptable standards. Furthermore, BCJV undertook monitoring during 2000 and 2001 as part of its contractual arrangements with Main Roads Western Australia. Monitoring was undertaken at a location to the west of the eastern tunnel vent. The reports on this monitoring indicated that for a two month period immediately prior to tunnel opening (March and April 2000) and for the periods May to June 2000 and September 2000 to March 2001, the concentrations of oxides of nitrogen, carbon monoxide, ozone and fine particles were well below the National Environmental Protection Measure standards, except for one day on which high particle levels were caused by a regional dust storm. The then Department of Environmental Protection agreed with BCJV that continued regular monitoring outside the tunnel was not warranted. (7) Yes, as described in the previous answer. (8) Not applicable. (9) This question should be referred to the Minister for Planning and Infrastructure.
(2) If yes, where is this data published? (3) If not, why not? (4) Does the Department of Environment or any other agency regularly monitor the air emitted from the exhaust stacks of the Northbridge tunnel? (5) If yes, where is this data published?

The modelling indicated that impacts from emissions were within acceptable standards. Furthermore, BCJV undertook monitoring during 2000 and 2001 as part of its contractual arrangements with Main Roads Western Australia. Monitoring was undertaken at a location to the west of the eastern tunnel vent. The reports on this monitoring indicated that for a two month period immediately prior to tunnel opening (March and April 2000) and for the periods May to June 2000 and September 2000 to March 2001, the concentrations of oxides of nitrogen, carbon monoxide, ozone and fine particles were well below the National Environmental Protection Measure standards, except for one day on which high particle levels were caused by a regional dust storm. The then Department of Environmental Protection agreed with BCJV that continued regular monitoring outside the tunnel was not warranted. (7) Yes, as described in the previous answer. (8) Not applicable. (9) This question should be referred to the Minister for Planning and Infrastructure.

Hon LJILJANNA RAVLICH replied: I thank the member for some notice of this question. The Minister for the Environment has provided a fairly lengthy response. I seek leave to have it incorporated in Hansard . Leave granted. The following material was incorporated - (1) The air inside the Northbridge Tunnel is continuously monitored by Baulderstone Clough Joint Venture (BCJV), the tunnel builder and contract operator, for Main Roads Western Australia, for the purpose of controlling the tunnel ventilation system. (2-3) The Northbridge Tunnel project was only subject to an informal assessment by the Environmental Protection Authority. This level of assessment was subject to appeal to the former Minister for the Environment. However, the former Minister for the Environment did not upgrade the level of assessment on appeal and hence there was no ability to place Ministerial Conditions on the project, such as publishing of monitoring data, in the final approval. Actual monitoring data collected by BCJV is recorded by the Tunnel Control & Management System, where it is retained for a minimum of one month. In addition, any breaches of air quality standards are immediately reported to Main Roads Western Australia. However, to date there have been none recorded. (4) No. (5) Not applicable.

However, the former Minister for the Environment did not upgrade the level of assessment on appeal and hence there was no ability to place Ministerial Conditions on the project, such as publishing of monitoring data, in the final approval. Actual monitoring data collected by BCJV is recorded by the Tunnel Control & Management System, where it is retained for a minimum of one month. In addition, any breaches of air quality standards are immediately reported to Main Roads Western Australia. However, to date there have been none recorded. (4) No. (5) Not applicable. (6) The potential impacts of emissions from the stacks were assessed via modelling during the environmental approval phase of Tunnel development. The modelling indicated that impacts from emissions were within acceptable standards. Furthermore, BCJV undertook monitoring during 2000 and 2001 as part of its contractual arrangements with Main Roads Western Australia. Monitoring was undertaken at a location to the west of the eastern tunnel vent. The reports on this monitoring indicated that for a two month period immediately prior to tunnel opening (March and April 2000) and for the periods May to June 2000 and September 2000 to March 2001, the concentrations of oxides of nitrogen, carbon monoxide, ozone and fine particles were well below the National Environmental Protection Measure standards, except for one day on which high particle levels were caused by a regional dust storm. The then Department of Environmental Protection agreed with BCJV that continued regular monitoring outside the tunnel was not warranted. (7) Yes, as described in the previous answer. (8) Not applicable. (9) This question should be referred to the Minister for Planning and Infrastructure.
