Brown coal is the reason for the rapid industrialisation of the Latrobe Valley, which lies about 150 km east of Melbourne. Some 80 per cent of Victoria's electricity is generated there, and other heavy industry includes the manufacture of paper, cement, and brown coal char. A coal-to-oil pilot plant is also under construction. The Latrobe Valley Airshed Study was established in 1977 to monitor air quality in the Valley and to assess the region's capability to accept increased emissions in the future. Four organisations - the SEC, the Environment Protection Authority of Victoria, CSIRO and the Latrobe Valley Water and Sewerage Board - are formally represented in the organisation of the Airshed Study.
