The year saw the development and part implementation of the Early Warning Modelling Tool and improvements to our rigorous load management protocol. These highly effective systems have played an integral role in the success of achieving zero non compliance. This is the best result since the comprehensive ‘real time‘ SO2 monitoring commenced, and is reflective of the amount of time and effort undertaken during the year by Anglesea employees. Further work is planned for 2009 with the introduction of the new northern meteorological station and full implementation of the Early Warning Tool. 2008 also saw a reinvigoration of our community consultation program. This included the development of the Alcoa Anglesea Newsletter, providing information to our local community on our operations, opportunity for people to become involved in our business and updates on the progress made with our SO2 Management Project. The Peregrine Falcon pair of Sheila and Havoc returned and successfully raised three male chicks, Midnight, Rocket and Stan. The webcam on www.alcoa.com/falcons generated unprecedented attention world-wide with correspondence coming from China, UK, USA, Germany, Netherlands, Canada, Italy and Poland. The drought continued in 2008 with only 501.4mm recorded at Anglesea this year. This is the seventh consecutive year of below average rainfall. Only 2000 and 2001 have provided any average, or above average, rainfall since 1996. After significant achievement in reducing town water use in previous years, several tube leaks and minor outages throughout the year resulted in the failure to achieve the 2008 target of 14.2ML. While this result is disappointing, employees are to be congratulated on maintaining a significantly low amenity use throughout 2008 of only 1.5ML. PLANTS OF THE ANGLESEA HEATH THATCH SAW-SEDGE (Gahnia radula) Size: Habitat: 1-2m H x 0.5-2cm W dry and valley sclerophyll forests, sclerophyll woodland, grassy low open forest, wattle tea-tree scrub Distribution: widespread in southern Australia Form: clumping perennial herb spreading by underground rhizomes Foliage: long, flat, raspy, deep green leaves with very sharp inrolled margins Flowers: ovate, loosely arranged chesnut brown panicle to 60cm, becoming black and pendulous; nuts dark brown to black most of the year Did you know? Plants are tolerant of Phytophthora cinnamomi. The vigorous rhizomes are useful in controlling soil erosion. Foliage has been used for roof thatching.

Busy at work with a great result with the SO2 load management protocol we rigorously implemented in 2008. We recorded zero exceedances of the ground level SO2 concentration (GLC) limit in the Anglesea township which is the best result since the comprehensive ‘real time‘ SO2 monitoring commenced. And personally you were involved in two special activities? Yes - I was lucky to share some terrific experiences with the KIDS Foundation. Colin Patterson and I volunteered at Camp Phoenix which was a fabulous camp in Queensland for burns survivors and their families. I also participated in the Charity Challenge which was a ‘once-in-a-lifetime’ Himalayan Trek to Nepal. What were the highlights from the Camp and the Trek? Camp Phoenix showed me how hard some families are doing it and how much we can all help. The courage and resilience some of the kids showed made me realise how trivial some of my own worries really are. To see the smile on the kids’ faces was an absolute highlight. The Charity Challenge was an inspirational trip starting at Kathmandu and trekking to the Langtang Valley in the breathtaking Himalayas. It was an eye opening trip - physically, mentally and emotionally challenging, with many fantastic friendships and memories I took away with me. ...MARK BOLLEMAN
