*466 TREASURER—AGENT-GENERAL FOR NSW—Mr Primrose asked the Minister for Finance and Small Business representing the Treasurer— (1) Who was the last Agent-General for NSW based in London? (2) When was the position officially abolished? (3) What were the official reasons for abolishing the position? (4) Is the NSW Government considering reinstating the position in London? (a) If so, why? (5) Is the NSW Government considering establishing positions of Agent-General in other locations, such as Brussels, Beijing, Washington, Tokyo, Singapore and Seoul? (a) If not, why not?

Answer— The last Agent-General based in London was Neil Pickard, and the office was abolished in 1992. The NSW Government is always looking to promote our State domestically and internationally. We seek to support and equip businesses to export, attract international investors, and capitalise on opportunities. Our representatives are already based in key international markets, however we are currently exploring options to raise the profile of our London office.

*467 PREMIER—AGENT-GENERAL FOR NSW—Mr Primrose asked the Special Minister of State, Minister for the Public Service and Employee Relations, Aboriginal Affairs, and the Arts, Vice-President of the Executive Council representing the Premier— (1) Who was the last Agent-General for NSW based in London? (2) When was the position officially abolished? (3) What were the official reasons for abolishing the position? (4) Is the NSW Government considering reinstating the position in London? (a) If so, why? (5) Is the NSW Government considering establishing positions of Agent-General in other locations, such as Brussels, Beijing, Washington, Tokyo, Singapore and Seoul? (a) If not, why not?

Answer— The NSW Government will always promote our State domestically and internationally. We seek to support and equip businesses to export, attract international investors, and capitalise on opportunities. Our representatives are already based in key international markets, and we are currently exploring options to raise the profile of our London office.

*468 WATER, PROPERTY AND HOUSING—ONLINE MONITORING SYSTEMS IN SEWERS—Mr Latham asked the Minister for Mental Health, Regional Youth and Women representing the Minister for Water, Property and Housing— (1) What recommendations were made by Sydney Water's 'Wastewater System Trade Waste Hazard Committee' for the installation of continuous online monitoring systems in sewers to monitor a range of key wastewater parameters and identify potentially hazardous events and significant changes in wastewater characteristics in: (a) 2006? (b) subsequent years? (c) How have the recommendations been implemented? (2) How many sewer monitoring systems does Sydney Water have in place as of September 2019? 676 Legislative Council Questions and Answers No. 115— Wednesday 16 October 2019

(3) What hazardous events have these monitoring systems identified in 2019? Answer— I am advised: 1 (a) In March 2006, the Wastewater System Trade Waste Hazard Committee discussed monitoring practices for hydrogen sulphide, flammable gasses and volatile organic compounds across the network's sewage pumping stations. The committee agreed to set up a trial of a new online wastewater monitoring equipment named "Envirodyne". This decision resulted in trial installations of online monitoring equipment at three sewage pumping stations at Camellia, Silverwater and Concord West. The monitor trial for hydrogen sulphide and flammable gasses proved to be a success while monitoring for volatile organic was unsuccessful. (b) In 2009, another trial commenced using a different device - S:CAN. Three pumping stations located at Camellia, Lidcombe and St Marys were involved. The trials showed the sensors could provide useful data but experienced poor reliability due to the harsh operating conditions. As a result, no S:CAN devices are currently deployed. In 2011, a collaborative project commenced with other water utilities and Griffith University to develop equipment for liquid monitoring. The equipment was developed and trialled until 2017. Sewage pumping stations at St Marys, Dunheved, Lidcombe and Penrith were involved. The monitoring tested for pH, turbidity, conductivity and temperature. Technology developed during this research contributed to the body of knowledge but didn't deliver a technological outcome which was viable for improving monitoring capability. (c) Sydney Water is actively investigating new technologies to improve the way wastewater is monitored to identify either potentially hazardous events or significant changes in wastewater characteristics. 2. As of September 2019, Sydney Water has continuous online monitoring systems in place at six sewage pumping stations. These systems mainly monitor for gasses. One site has liquid and gas monitoring. SP0067 Camellia - (gas and liquid) SP0071 - Rozelle SP0138 – Padstow SP0297 – Taren Point SP0327 – Chipping Norton SP0477 – Lidcombe 3. Throughout 2019 Sydney Water's monitoring systems have identified 24 events involving the Lower Explosive Limit (LEL). LEL is the lowest concentration (percentage) of a gas or a vapor in the air capable of producing a flash of fire in the presence of an ignition source. These events were managed in accordance with existing protocols. These events were managed in accordance with existing protocols and did not result in adverse outcomes.

*469 HEALTH AND MEDICAL RESEARCH—NUCLEAR MEDICINE UNITS AND DECAY TANKS—Mr Latham asked the Minister for Mental Health, Regional Youth and Women representing the Minister for Health and Medical Research— (1) How many NSW hospitals have nuclear medicine units? (2) Which hospitals have decay tanks available to them? (3) What guidelines have the Australian Department of Health issued for decay tanks at these hospitals? Answer— (1) There are 17 public hospital Nuclear Medicine Departments in NSW. There is also a wide range of private radiology practices utilising nuclear medicine. (2) Liverpool and Royal Prince Alfred public hospitals have Nuclear Medicine units which utilise on-site decay tank systems for the management of radioactive waste. (3) The Australian Radiation Protection and Nuclear Safety Agency published a safety guide for Predisposal Management of Radioactive Waste (2008) as part of the Radiation Protection Series. 677 Legislative Council Questions and Answers No. 115— Wednesday 16 October 2019

*470 BETTER REGULATION AND INNOVATION—SAFEWORK NSW—Mr Latham asked the Minister for Finance and Small Business representing the Minister for Better Regulation and Innovation— (1) What recommendations have been made by SafeWork NSW following its investigation into the death of a Veolia employee, sub-contracted by Sydney Water, who had been working at the Brickpit site at Homebush in early May? (2) What other workers were affected by sewerage fumes at the site? (3) What does the SafeWork NSW report say about the health and work safety of these workers? (4) What action is the Government taking in response to the SafeWork NSW Reports into these matters? Answer— 1-4. Safework has begun investigations and the matter is being considered by the Coroner. As the investigation is ongoing Safework is unable to comment further at this time.

*471 TRANSPORT AND ROADS—CHARLEYONG BRIDGE OVER THE MONGARLOWE RIVER—Ms Boyd asked the Special Minister of State, Minister for the Public Service and Employee Relations, Aboriginal Affairs, and the Arts, Vice-President of the Executive Council representing the Minister for Transport and Roads— (1) What is the full cost of demolishing the existing Charleyong Bridge over the Mongarlowe River? (2) What costings were used as the basis for the decision to remove the existing Charleyong Bridge? (3) What has been the full cost of reinforcing ⁄ maintaining the existing Charleyong Bridge over the past ten years (e.g. the cost of the steel reinforcements installed recently)? Answer— I am advised: (1) The existing bridge will be demolished as part of the $23 million Charleyong Bridge replacement project. (2) The Timber Truss Bridge Conservation Strategy (2012) identifies Charleyong Bridge as requiring replacement. Factors influencing this decision included load carrying capacity, narrow bridge width, poor access and frequent and expensive ongoing maintenance needs. (3) Maintenance expenditure for the existing Charleyong Bridge since 2016 is $594,000. Prior to 2016, bridge maintenance works were recorded as a lump sum for the region and not allocated by bridge.

*472 TRANSPORT AND ROADS—TUG BOATS BY CRUISE VESSELS IN SYDNEY HARBOUR—Ms Boyd asked the Special Minister of State, Minister for the Public Service and Employee Relations, Aboriginal Affairs, and the Arts, Vice-President of the Executive Council representing the Minister for Transport and Roads— In relation to the usage of tug boats by cruise vessels in Sydney Harbour: (1) Why are tug boats mandatory for cruise vessels in section 2.106.2 of the Harbour Masters Directions for Sydney Harbour but then exempt in 2.106.3? (a) What would the cost be to the Port Authority of NSW to mandate compulsory towages to vessels arriving at Sydney Harbour? (2) What is the current level of risk posed by cruise vessels without tug boats to the Sydney Harbour Bridge and Sydney Harbour Tunnel from mechanical and⁄or human error? (a) What would be the cost to the Port Authority of NSW in the event that a cruise vessel came into contact with the Sydney Harbour Bridge and⁄or the Sydney Harbour Tunnel? (b) What is the lead time for booking tug boats to assist a vessel that may have contacted or be in danger of contacting the Sydney Harbour Bridge and⁄or Sydney Harbour Tunnel?

Answer— I am advised: (1) Seagoing passenger vessels are exempt from the additional requirements applying to them if the conditions set out in Section 2.106.3 of the Harbour Masters Directions are met. 678 Legislative Council Questions and Answers No. 115— Wednesday 16 October 2019

(2) The Port Authority assesses the risks associated with commercial vessels manoeuvring in Sydney Harbour and applies appropriate mitigation measures. The Port Authority periodically reviews its risk mitigation measures. They were most recently reviewed in 2019 with the assistance of internationally recognised independent experts. The recommendations are expected to include enhancements that will even more closely align the measures taken in Sydney Harbour with best practice elsewhere.

*473 ATTORNEY GENERAL—FEDERAL EXPOSURE DRAFT BILL ON RELIGIOUS DISCRIMINATION—Mr Latham asked the Minister for Education and Early Childhood Learning representing the Attorney General, and Minister for the Prevention of Domestic Violence— (1) Has the NSW Government made a submission to the Federal exposure draft bill on religious discrimination? (a) If so, what are the details?

Answer— No. The NSW Government commonly does not provide submissions to Commonwealth Government public consultations.
