Scotland Country summary Scotland's environmental issues are overseen by a separate agency: the Scottish Environmental Protection Agency (SEPA). This body has taken on the combined responsibilities of Scotland's district and islands councils for waste regulation and air pollution control, as well as those of Her Majesty's Industrial Pollution Inspectorate and the former river purification boards. While solid waste statistics are comprehensive, those for liquid and gaseous wastes are not. The consolidation of authority into SEPA should address this issue in the future. SEPA has discovered unexpectedly that it failed to provision for VAT in its budgets. In consequence it faces budgetary restraints and has suggested that it may have to scale down its operations in the initial year of operation. It is working to develop parallel documents to those produced by the Environment Agency of England and Wales. There is abundant landfill capacity in Scotland from very large quarries developed for rock abstraction virtually all of which are ideal from the point of view of site engineering purposes for landfill use. Most Scottish waste remains in Scotland recycling, treatment or disposal. The country is virtually self sufficient. Arisings Aberdeen Highlands
data is reasonably accurate, the only waste leaving Scotland comprising special waste amounting to 2% of total arisings. Disposal gate fees are the lowest in the UK, typically in the region of £5 to £8 per tonne excluding tax. Strathclyde has the

electronics sector in silicon glen. In terms of water supply, Scotland also has an abundance – both in volume and quality. This is a key element in attracting inbound industrial investment. Supplies of water are likely to be enhanced if the predictions of global warming experts are also confirmed – that there will be an upward shift in volumes of rainwater deposition in the north of the country as the south westerly streams move northwards. There is thus unlikely to be a long term strategic shortage in this area. Relatively small volumes of gaseous waste emissions are reported although

Industry attitudes Biffa findings from "Waste: A Game of Snakes and Ladders?" indicated that Scottish industry spends the least amount of money on waste management, yet along with the North West and North East, it is most likely (39%) to think that waste control is a major factor in terms of competitive edge. Compared with an average of 25% of companies, Scotland leads the way (39%) in monitoring the waste practices of competitors.

Country audit Solid waste issues Waste arisings Total arisings for the region on which there is certainty are quoted at 13.5 million tonnes based on a sample base of 5 million (100% of the country's population). Figure 1 illustrates the percentage split by waste stream for the total waste arisings for the country estimated at 13.5 million tonnes. This figure represents 8.8% of the total estimated tonnage for Great Britain. 98.5% of the total controlled waste arisings in 1993 remained in Scotland NB: The figures on these pages are subject to the qualifications of our auditors.

There is plenty of landfill capacity in Scotland from very large quarries developed for rock abstraction – virtually all of which are for site engineering purposes in terms of geological capability.

amounts to 0.03 million tonnes or 2% of the estimated total arisings. Variations are due to the net 'export' of 30,000 tonnes of special waste to appropriate treatment and disposal facilities in other parts of Britain.

Scotland's complete data sets for arisings obviously provide excellent levels of accuracy. Even so, SEPA intends to improve matters further by collecting and publishing more detailed statistics (including landfill capacity) to assist in the creation of new waste management policies for Scotland. They suggest that, overall, the licensed capacity is sufficient for Scotland’s needs for the next 5 years.

Landfill capacity Scotland has abundant landfill capacity (635 licensed or 'resolutioned' sites in 1993) with costs accordingly very low in comparison to other parts of the UK – typically in the region of £5 to £8 per tonne excluding tax. However, because the largest capacity classification, into which 366 sites fall, is so broad (the range is 75,000 m3 to 7,000,000 m 3), it is not feasible to calculate landfill capacity accurately in terms of years remaining, although SEPA suggests the overall licensed capacity is sufficient for the next five years or more.

The district is also responsible for more than half Scotland's total tonnage of special waste disposals.

Around 16,000 tonnes of asbestos and 2,900 tonnes of liquid special waste were landfilled in Scotland in 1993. Scotland has

in critical loads being exceeded in certain areas. Critical loads for fresh waters are also exceeded, particularly in areas of the north western Highlands. Deposition modelling indicates that even with the EC directive on SO2 (see note E8) in place, critical loads will still be exceeded in some small areas of Scotland. UNECE vegetation guidelines for SO 2 and NO2 (see note E9) were exceeded at urban monitoring sites in Scotland in 1994/5. Fig. 7 Sources of CRI emissions by

increased in pH value by 0.5, from 0.7 to 1.2 over the past 150 years. The rise is attributed to atmospheric pollution from industrial sources as, before the advent of large scale industry, lake flora was largely unaffected. Studies indicate that the rate of acidification increased markedly between 1930 and 1950.
