SUMMARY The Environmental Quality Monitoring Program (EQMP) is an important tool for managing the marine environment of Cockburn Sound. The EQMP has been developed in partnership with stakeholders to provide information on the effectiveness of management recommendations and actions promoted in the Environmental Management Plan for Cockburn Sound and its Catchment 2005 (EMP). Data collected from the EMP is used by the CSMC to produce annual Report Cards on the health of Cockburn Sound. The EQMP for Cockburn Sound comprises monitoring conducted by industry groups, local, state and federal government. As such, a key step in the development of this program is the compilation of information on current monitoring activities occurring in Cockburn Sound. It is intended that the EQMP will be an evolving document which is periodically updated to reflect on-going amendments to the various monitoring programs undertaken by a range of stakeholders in Cockburn Sound. The objective of this document is to provide a summary of on-going monitoring programs which contribute regular data to the EQMP for Cockburn Sound. This document also contains information on the current status of data management, including access to data. The Cockburn Sound Management Council aims to consolidate data collected as part of the program into a single, publicly accessible database. An outline of the current mechanisms used by the Cockburn Sound Management Council to report on data collected as part of this program is also included.

BACKGROUND The Cockburn Sound Management Council (CSMC) is responsible for coordinating an Environmental Quality Monitoring Program (EQMP) in Cockburn Sound. The EQMP is an important tool for managing the marine environment of Cockburn Sound. It has been developed in partnership with stakeholders to enable the CSMC to produce Report Cards on the health of Cockburn Sound and to provide information on the effectiveness of management recommendations and actions in the Environmental Management Plan for Cockburn Sound and its Catchment 2005 (EMP). The EQMP for Cockburn Sound comprises monitoring conducted by industry groups, local, state and federal government. As such, a key step in the development of this program is the compilation of information on current monitoring activities in Cockburn Sound. In total there are twelve annual monitoring programs and more than four other regular programs undertaken in Cockburn Sound. These programs are undertaken by various stakeholders with individual objectives. Results of most monitoring programs contribute to the production of the annual Report Cards for Cockburn Sound. A map outlining the programs and associated sites that form the EQMP is provided below (see Map 1- Environmental Quality Monitoring Sites).

OBJECTIVE The objective of this document is to provide a summary of on-going monitoring programs which contribute regular data to the EQMP for Cockburn Sound. The EQMP comprises data and information for a range of physical, chemical and biological indicators collected over a number of spatial and temporal scales. This data forms the basis for the development of Report Cards for Cockburn Sound.

Jervoise Bay Northern and Southern Harbour Water and Sediment Quality Monitoring Programs

Custodian LandCorp – Australian Marine Complex Objective This monitoring program is part of commitments under the Jervoise Bay

developments: EPA (1996) Breakwater Extension, Northern Harbour Precinct, Jervoise Bay EPA Bulletin 836; and EPA (1998) Industrial Infrastructure and Harbour Development, Jervoise Bay, EPA Bulletin 908 EPA Ministerial Conditions Statement 490.

Ministerial Conditions specified a five-year monitoring program to be developed as part of the EMP for the Northern Harbour. This five-year period expired at the end of 2002. A change in proponent from Department of Industries and Resources now sees the Northern Harbour managed by LandCorp. Post-construction Northern Harbour water quality monitoring showed that groundwater nitrogen inputs to the harbour were a significant driver of poor water quality within the harbour. The Jervoise Bay Groundwater Recovery Scheme (GRS) was subsequently implemented as a condition of approval for the Jervoise Bay Southern Harbour development (EPA Audit Table items 490:P24.1 and 490:P24.2; EPA 1998) to extract groundwater which was high in dissolved inorganic nitrogen. As part of this scheme, it was decided that although the period of monitoring required for the conditions of approval had lapsed, water quality monitoring should continue in order to measure the effects of groundwater nitrogen removal on water quality in the Northern Harbour. The Construction and Operations EMPs developed for the Southern Harbour project, specified under Ministerial Conditions and Proponent Commitments for Statement 490, requires annual water and sediment quality monitoring to occur for five years post construction. This monitoring program addresses the water quality requirements of audit table items M5.1:1, M5.1:2, M5.2, M5.3:1, P6.1, P6.2, P6.3:1 and the sediment quality requirements of P7.1 and P7.2.

^The Carnac Island site was changed in 2005 due to encroachment of a large sand sheet across the site. This was causing a loss of Posidonia and an increase in Amphibolis cover which made interpretation of the data difficult. * Data collected from these sites have not been incorporated into the Cockburn Sound Report Cards for 2006-2007 as these sites occur in Owen Anchorage.

Videography - A circular transect of 5m radius around the central star picket, commencing due east, at approximately 1m above the sediment. Close up footage of benthos

- - -

In situ: permanent quadrats A tape measure is attached to a central star picket in the sediment. The diver then swims holding the tape measure and following a pre-determined compass bearing until a pre-determined distance is reached and locates the start of one of the four 10 m transects located at the site. The transects are labeled with cable ties, the start (0m) picket having 1-4 cable ties fastened through the star pickets and the end having 1-4 cable ties attached as loose loops. Each of the permanent quadrat sites is marked with a metal picket. Transect 1 has 1 cable tie at each end, transect 2 has 2 cable ties at each end, and so on. The diver attaches a tape or pre-marked rope at the start of the transect and extends this to the end. At the predetermined distances along the transect, a purpose-made stainless steel quadrat is placed over four permanent markers located in the sediment. Shoot density measurements are taken for each of 6 quadrats on each of the 4 transects at each site. It should be noted that there was a change in methodology over 2003-05 as fixed quadrats were introduced and the degree of replication increased. Under the new approach there are 24 permanent quadrats and all zero shoot density counts are recorded.


- 30 -

In situ: depth limit transects A rope with marked 2m increments is placed along the transect between the first and last picket. The bottom right corner of a quadrat is lined up with the increment on the rope. The placement of the quadrat is commenced at the shallow end of the transect on the left-hand side and repeated at every 2m increment as marked on the rope.

MPN/100mL Grab samples collected at waist depth from approximately 30cm below the water surface – 250ml sterilised container – stored on ice until analysis

A test portion of sample is aliquoted and the Enterolert reagent powder is added. Once dissolved the contents are added to a Quanti – Tray. This is placed through a sealer, which seals all the liquid in the 49 large and 48 small wells. The Quanti – Tray is then incubated at 41°C for 24 hours. Following incubation the Quanti - Tray is removed from the incubator and examined under ultra-violet light. The number of fluorescent wells is counted and compared to the Quanti - Tray Most Probable Number charts and a final result obtained on the number of Enterococci present in the sample per 100mL. The Enterolert method uses 4-methylumbelliferyl-β-D-glucoside (MUG) as the defined substrate nutrient indicator. This compound, when hydrolysed by Enterococcal- β-glucosidase, releases 4-methylumbelliferone which exhibits fluorescence under UV365 lamp.

The WET testing data is to be interpreted in terms of acute toxicity end-points (ie LC50 levels). LC50 -–lethal concentration that kills 50% of test organisms in a given time, usually after 96hrs for fish and 48hrs for some invertebrates. EC50 – effects concentration, is usually used when it is difficult to accurately determine mortality. Microtox, unicellular algal growth tests, macroalgae germination tests, copepod reproduction 21 day tests, pink snapper 7 day larval growth test.

Toxicants in Sediments Survey Monitoring Program

Custodian Cockburn Sound Management Council Objective To gather information on contaminant types in sediments to allow reporting

against the environmental quality criteria set for the maintenance of ecosystem integrity in high and moderate ecological protection areas. This survey follows previous sampling and analysis of sediments undertaken by the Department of Environmental Protection as part of the Southern Metropolitan Coastal Waters Study 1991-1994 (SMCWS). As part of this study, an initial survey was conducted in November 1991 and was followed by further sampling in February 1994 in areas of highest contamination in the 1991 survey. In 1999, the Kwinana Industries Council (KIC) commissioned D.A Lord & Associates Pty Ltd (DAL) to coordinate a survey of contaminant levels in a broad range of sediment types in Perth’s coastal and estuarine waters.

Survey of Metal Body Burden in Edible Fish Species in Perth’s Coastal Waters

Custodian Department of Environment and Conservation – Marine Ecosystems Branch

Objective To establish the background levels of selected heavy metals in the edible

portion of the flesh of a range of recreational and commercially important fin-fish in the coastal waters off Perth, WA.

Sampling Fieldwork: Department of Environment – Marine Ecosystems Branch.

This is a once-off program that is still in progress. The sites north of Cockburn Sound were sampled March - June 2005.

Sample area: A series of sites have been located over sandy substrates along approximately

9 offshore transects between Ocean Reef and Becher Point, including one in Owen Anchorage, two in Cockburn Sound and one in Warnbro Sound. The sites have been located to represent inshore (<200m offshore), lagoonal (200 – 3000m offshore) or offshore (3000 – 8000m offshore) environments. Two sites have also been established in the mid-shelf north and south of Rottnest Island.

Site locations: Indicative site locations shown in site location map. Site Location Map (see over):

Parameters and methods Sampling was targeted for the collection of Sillago sp (Whiting) using lines and baited hooks. Sillago are selected because of their ubiquitous nature, they are commonly targeted by recreational anglers and their diet includes filter-feeding invertebrates such as polychaete worms which inhabit sediments where heavy metals can accumulate. Other fish species were opportunistically sampled in order to obtain samples of species higher up the food chain.

DATA MANAGEMENT A data management system is necessary to ensure Environmental Quality Monitoring Program data is stored in a single location, consistent format and with appropriate quality assurance. The CSMC is in the process of investigating a means for coordinating the collation and consolidation of all Cockburn Sound monitoring data into a single database. A contractor will be employed for this purpose. Once this occurs it is proposed that stakeholders, resource managers and the community can access Cockburn Sound monitoring data stored on a single database.

REPORTING

Report Cards

The Cockburn Sound Report Cards have been developed to provide information on the health of the Cockburn Sound marine environment to stakeholders and the community. As part of the State Environmental (Cockburn Sound) Policy 2005 the Cockburn Sound Management Council is also required to prepare an annual Report on the state of Cockburn Sound. This Report is submitted to the Minister for the Environment and tabled in parliament. A report card for each environmental value in Cockburn Sound has been prepared every year since 2001. Report card maps are also prepared which show site specific information for individual indicators. The Report Cards are available on the Cockburn Sound Management Council website: http://csmc.environment.wa.gov.au/. Benchmarks, known as Environmental Quality Criteria under the State Environmental (Cockburn Sound) Policy have been developed for Cockburn Sound and can be used to determine whether the Environmental Values for Cockburn Sound are being protected. The five environmental values for Cockburn Sound are:

• Ecosystem Health

• Seafood safe for eating

• Aquaculture

• Recreation and aesthetics

• Industrial water supply.

The Cockburn Sound report cards are derived by comparing monitoring data, undertaken by a variety of stakeholders, with the environmental quality criteria following the process defined in the Environmental Quality Criteria Reference Document.

Web Reporting System

The Cockburn Sound Management Council has developed a web reporting system that builds on the existing annual report cards and uses report card maps to indicate specific locations of concern and areas requiring additional monitoring effort. The report card maps for ecosystem health combine the reporting of the high and moderate protection areas. The web reporting system aims to provide clear and jargon-free information on monitoring activities and results to stakeholders and the community. The report card maps have been developed for the main concerns to ecosystem health being:

• tributyltin (TBT) concentrations in the sediments in Jervoise Bay and Careening Bay;

• seagrass health in Mangles Bay and Kwinana; and

• phytoplankton biomass along the eastern foreshore and within Mangles Bay.
