MINUTES TECHNICAL COMMITTEE MEETING 15 August 2019, Woollahra Municipal Council Contents Presentations…………………………………………………………………………………………………1 Administrative Matters .................................................................................................................... 2 Member Council Roundtable ........................................................................................................... 4 SCCG Activities Update .................................................................................................................. 7 General Business............................................................................................................................ 9 1. Presentations BA introduced the Presenters: Michele Cassidy, Colin Besley and Nathan Harrison from Sydney Water and handed over to Michele to commence the presentation on the Microbial Source Tracking Pilot Study. Key points from the presentation are below and the presentation slides are attached at the end of the minutes. Sydney Water, Wet Weather Overflow Monitoring Program, Microbial Source Tracking Study • Wet weather overflow monitoring – working with CSIRO on a 9-step monitoring approach to assess public health risk. • Microbial source tracking pilot study being undertaken to identify DNA markers in water samples to determine sources of water pollution e.g. human/non-human, sewer or stormwater which can assist in managing solutions and prioritising pollution issues and higher risk sites. • This QMRA has more targeted sampling methods than what’s currently used in Beachwatch program. The pilot will develop a threshold value for markers to use alongside Beachwatch enterococci data. • 5x times more effective than caffeine methods of sampling. • Sydney Water is not working with local council at this stage however will approach councils once confident with results of the pilot. Capability is there to apply to other specific council sites once the pilot has been completed. • Opportunity was identified in its usage for making the Parramatta River a swimmable area. • Public survey component will be observational survey only observing level of user contact, frequency and duration of contact to identify exposure risks. • The 9-step process will have progressed within the next 12 months however the entire framework will take approx. 2.5 years to complete. Discussion points • In some areas there is an issue of people flushing dog poo down the toilet – is this likely to impact on the microbial source tracking study outcomes? Noted that the small concentration of dog poo in sewer is unlikely to impact on results. • Potential for this study to link to / identify illegal connections • Councils can work with Sydney Water to identify likely causes of pollution in the catchment e.g. dogs/bat colonies. • EPA will be changing Sydney Water’s licence with frequency targets being changed to a point system based on risk-based framework. Page 1 of 9 BA introduced the second presenter Hendrik Clasie, General Manager Industry and Environment, NSW Maritime (Transport for NSW). Main points form the presentation are provided below. Transport for NSW (Maritime) • Structure: NSW Maritime Centre for Maritime Safety Port Authority of NSW - Ground Staff i.e. - Strategic - Operate as a business customer service, Safer Systems Framework – - Relates solely to trade environmental integrated with maritime i.e. interests services boats and ramps • The Environmental services team work 7 days a week 6am-6pm within 5020ha of Sydney Harbour at 211 locations to remove hazards to navigation, litter/waste within navigable waters of Sydney Harbour up to the high tide mark on specific beaches. • Data collected shows the team has visited 23772 sites per year, collecting 2085 cubic metres of rubbish (26% manmade) and 3121 major navigational hazards throughout the year. • Navigational channels and known hotspots are prioritized. Hotspot areas are based on tides/wind etc. • Monitoring of pumping facilities on Sydney Harbour is a responsibility of Maritime. There are three publicly accessible waste pumping stations within Sydney Harbour – King Street Wharf, White Bay and Black Wattle Bay. Data shows 12.7 million litres of sewage was recovered from 14583 charter vessels using the public pump out facilities. • Maritime investigating a new location for another pump facility in Sydney Harbour. • Responsible for Maritime Pollution Response (EMPLAN) e.g. oil spills in Sydney Harbour. Port Authority is the combat agency where there is a port and the Foreign Rescue NSW is the authority for inland waterways/rivers. • Transport for NSW work on the basis of ‘polluter pays. If they are required to clean up a pollution event caused by another party, they can legally gain the funds back from the polluter (insurance etc). • Centre for Maritime Safety advocates for safe boating to address user conflicts. Noted that a jetty will be built at La Perouse for boats to moor from to address conflicts with swimmers in the swimming zone. • Data sharing in place with NSW Health to gather information on injuries etc from boating. Discussion Points • Who controls navigation within Private Marinas? − Best contract is Property Team within Transport for NSW, may also be dependent on the lease agreement with the marina. • Management of sand build up – Woollahra Council − Build-up of sand - entering private properties and blocking storm water outlets, causing flooding. Question of whether TfNSW had received similar reported incidents and if so, how this was managed? E.g. Hawkesbury River - build-up of alluvial sands create blocks in the waterway. Presenters were thanked for their presentations. 2.

    5. Parramatta

    5. PARRAMATTA 5.1 Introduction Parramatta Local Government Area occupies an area of 60 square kilometres, straddling the upper reaches of the Parramatta River, in eastern parts of the western Sydney region. There is a marked difference in landscape type between those areas to the north and south of the Parramatta River. To the south and west, undulating Wianamatta shales of the Fairfield Basin are broken by low-lying fingers of Quaternary alluvium along the major creek lines such as Prospect Creek, Duck River, the upper parts of Toongabbie Creek and their tributaries. A small sandstone outcrop along an upper section of Duck River has little impact on topography, but is reflected in the disjunct occurrence of sandstone species. To the north of the river the Hornsby Plateau-Cumberland Plain interface is marked by steep rises. Small remnants of Wianamatta shales occur on ridge-tops and deep valleys are incised into Hawkesbury sandstone along creeks draining from the plateau. Soil landscapes reflect this variation in geology across the LGA. To the south and west the dominant soil landscape on the shales is Blacktown, with Birrong on the alluvium in drainage lines along the creeks. In the north-east beyond the still undulating shale and Blacktown soil landscape close to the river, the edge of the Hornsby Plateau produces a complex mosaic of soil landscapes including the shale-based Glenorie on the ridges, sandstone-based Gymea and Hawkesbury on the slopes and in the valleys, and patches of Lucas Heights associated with outcropping Mittagong Formation lying between Wianamatta shale and Hawkesbury Sandstone.
