ANGLESEA ENVIRONMENT REPORT JANUARY 2010 2009 - the year in review 2009 was a very busy year for the Anglesea Power Station’s environmental team. Not only did we complete the “every day” work such as the EPA annual report, reporting to the National Pollutant Inventory, our community reporting and participating in a review of our ISO14001 systems, but we also completed a long list of additional work, including: - 2009 Maintenance Shutdown; - Submission and approval of EPA Energy and Resource Efficiency Plan; - Reaccreditation of Wastewise certification to Gold Level; - Commissioning and 53V Audit of the SO2 Air Quality Control System (AQCS); and - Reporting to the new Federal Government National Greenhouse and Energy Reporting Scheme (NGERS). Here is an update on how we went during 2009 in our major areas of focus that we report on every month on the back page of this report.: Emissions to Air: one reportable environmental incident involving an exceedance of the EPA Air Quality Objective of 200 ppb SO2 in March. Greenhouse Gas: GHG Efficiency slightly exceeded the target of 1.20, with an annual average of 1.21. This is an area of focus for 2010, and we plan to improve this efficiency to below 1.20. Due to the introduction of NGERS, our GHG emissions have had to be recalculated back to Jan 2008. This may account for any discrepancies in GHG figures that you see in this report compared to previous versions. Town Water Use: during our shutdown we used 2.0 ML of water for our maintenance activities. However, our annual town water use exceeded our 2009 target of 14.2 ML by exactly that amount. As this is an irregular activity, we plan to be able to meet our target in 2010. Bore Water Use: our bore water use was well below target for 2009. 2814 ML were used, as opposed to our target of 4000 ML. Waste to Landfill: the amount of non-recyclable waste that was sent to landfill in 2009 was 11.64 tonnes. This did not compare favorably to our target of 8.0 t. The reason for the large volume of waste produced was mainly the maintenance shutdown and the several hundred contractors on site during that time period. However, on a positive note, no prescribed waste requiring landfill was generated in 2009. In addition to all this, we helped to fight a planned burn which broke containment lines and threatened our perimeter, we commissioned our new Northern Meteorological station to help with predictive alarms for the AQCS, our Peregrine Falcon pair - Sheila and Havoc - produced three healthy chicks, we commenced work on our Cultural Heritage Management Plan and we rehabilitated a small area in the mine lease of 0.658 ha! We have set new environmental targets for 2010. These can be seen on the last page of this report. We look forward to working hard in 2010 to achieve these targets. ANIMAL OF THE ANGLESEA HEATH TIGER SNAKE (Notechis scutatus) Size: Description: average 1 m; maximum 2 m despite the name, the snake may have no striping at all; markings are extremely variable and colour varies, from jet black, through yellow/orange with grey bands to sandy grey with no bands; typical forms are a black or dark olive snake with either no bands or faint yellow or cream bands Distribution + Habitat: the common tiger snake is found in southern and eastern Australia; wide ranging from dry rocky areas, woodlands, to wet marshes and grasslands. Food: mainly feeds on small birds and mammals under 300g in weight; also lizards + frogs Tiger snakes are aggressive if disturbed or threatened, however they will not bite unless provoked. Venom is highly toxic but human death from snake bite is uncommon as anti venene is readily available.

What did this involve and why was it important to do? The process involved having a focussed two hour session with a select group of employees who have knowledge of the supply, cost, infrastructure and consumption of diesel at Anglesea. The outcome is we now have a detailed flow map and have identified 11 opportunities to potentially reduce our diesel usage rate. Diesel is a large annual cost to the Anglesea business and also environmentally is considered a “significant resource” under our ISO14001 program. Finding ways to reduce our diesel use per MWh not only can save the business dollars, but also reduces our environmental footprint. How do you see your role in ABS and the environment fitting together? ABS defines how we do business. My role is to help develop systems and teach in the “thinking” of ABS so we are all better equipped to continually improve our business in areas of cost, time, quality, environment and health and safety. improving in these areas is the key to growing our operations and meeting the expectations of our shareholders and our communities. ...STEVE DISCIASCIO
