The proposed penstock line follows an old shieling track leading to the headwaters of the Allt Dubh, but no significant archaeological features were identified, and there are no recommendations for further work. 2 Allt Dubh Hydro, Achnasaul, Loch Arkaig: December 2012 Contents Introduction ................................................................................................................................................... 4 Site Location and Background ...................................................................................................................... 5 Legislation and Policy ................................................................................................................................... 6 Methodology ................................................................................................................................................. 8 Results ........................................................................................................................................................... 9 Discussion ................................................................................................................................................... 10 Recommendations ....................................................................................................................................... 10 Conclusions ................................................................................................................................................. 10 Sources ........................................................................................................................................................ 11 Table of Photographs .................................................................................................................................. 11 Illustrations Cover: View south along track from north-east of intake site Plate 1 Powerhouse site. ............................................................................................................................ 10 Figure 1 Project location .............................................................................................................................. 4 Figure 2 Scheme layout ............................................................................................................................... 5 Figure 3 Extract from William Roy Military Survey (1747-54) .................................................................. 7 Figure 4 Ordnance Survey 6 inch map, surveyed 1872 ............................................................................... 9 Figure 5 Photo locations ............................................................................................................................ 12 Acknowledgements The survey was undertaken by John Wood MA, MIFA, MAHI.

Not reproduced to scale Introduction Archaeological desk-based and walk-over surveys were undertaken to identify and record the nature and extent of cultural heritage features that might be affected by the construction of a run of river hydro-electric scheme. The work was carried out according to the Institute for Archaeologists’ published standards and guidance. 18 18 IfA Code of Conduct (2010), Standard and Guidance for Archaeological Desk-based Assessment (2008), and Standard and Guidance for an Archaeological Watching Brief (2008). 4 Allt Dubh Hydro, Achnasaul, Loch Arkaig: December 2012 The surveyor is confident that this report reflects the extent of the known cultural heritage resource, so far as this can be determined by a walkover survey and desk-based assessment. It remains possible that buried or concealed remains which could not be identified in this project may exist in the study area. Figure 2 Scheme layout Courtesy of Eden Environment Ltd. Not reproduced to scale Site Location and Background The proposed development will require the construction of an intake, a penstock, a powerhouse and outlet to Loch Arkaig. (Figure 2). The proposed penstock line runs from the intake at approximate OS grid reference NN 16185 91072 at about 300m above sea level, southwards to the powerhouse site at approximate OS grid reference NN 15288 89442, at about 63m above sea level. The outflow then runs back to the Allt Dubh, about 20m or so from the powerhouse. In all the scheme is about 2km long. The upper parts of the line are open moorland with scattered trees on the lower slopes. The Allt Dubh has cut a narrow, steep sided valley, increasingly wooded as it descends. The line mostly follows the route of an old track which seems to have served shielings at the headwaters of the Allt Dubh. These were not visited. The proposed powerhouse site is in a hollow on the eastern side of the river, adjoining a former road bridge, now superseded. The track from the hill has been diverted here to avoid Achnasaul house and garden. 5 Allt Dubh Hydro, Achnasaul, Loch Arkaig: December 2012 Legislation and Policy The common principles underlying international conventions, national legislation and local authority planning policies are that cultural heritage assets should be identified in advance of development and safeguarded where practicable; if disturbance is unavoidable appropriate recording of features and recovery of portable artefacts should take place. The European Convention on the Protection of the Archaeological Heritage (revised), known as the Valletta Convention, ratified by the UK government in 2000, contains provisions for the identification and protection of archaeological heritage both under water and on land, preferably in situ , but with provisions for appropriate recording and recovery if disturbance is unavoidable. The same principles run through national legislation and national and local policies. European Directives on environmental impact assessment, which include the cultural heritage, have been incorporated into UK legislation including the Environmental Impact Assessment (Scotland) Regulations 2011. The Ancient Monuments and Archaeological Areas Act 1979 allows for any ‘monument which in the opinion of the Secretary of State is of public interest by reason of the historic, architectural, traditional, artistic or archaeological interest attaching to it’ and deemed to be of ‘national importance’ to be scheduled under the Act. This has the effect of requiring the consent of the Scottish Ministers (Scheduled Monument Consent), for any works which would have the effect of demolishing, destroying, damaging, removing, repairing, altering, adding to, flooding or covering up the monument. Failure to obtain this consent before carrying out such work is a criminal offence. In 2009 Historic Scotland published revised criteria for the determination of ‘national importance’ in Scottish Historic Environment Policy (SHEP) Cultural heritage features not scheduled under the 1979 Act are covered by the Town and Country Planning legislation. The Planning (Listed Buildings and Conservation Areas) (Scotland) Act 1997 and amendments governs the listing and protection of buildings and areas of special architectural or historic interest. Other planning legislation 19 requires planning authorities, prior to granting planning permission, to consult Historic Scotland on any development proposals that may affect the site or setting of a Scheduled Monument, an A-Listed building or an Inventoried Garden or Designed Landscape. The Town and Country Planning (Scotland) Act 1997 and the Planning etc (Scotland) Act 2006 confirm that the historic environment (whether covered by statutory protection or not) is a material consideration in the planning
