into adjacent soils.
Where tracks are situated near deep peat, drainage systems will be adapted to ensure that the water table in the adjacent peat is not
affected or only affected over a short distance. For example, drainage ditches along the track will be as shallow as possible but sufficient
to drain rainfall from the track surface and to prevent runoff flooding the track. The track surface will be near the adjacent peat surface
and cross-drains will be installed at or just below the track surface. These measures will ensure that runoff within the upper peat layer
(acrotelm) is not blocked by the track. The track base will be constructed using suitably permeable graded material such that the slow
movement of water in the deeper peat layers is not significantly affected by the track.
Watercourse Crossings
Two new watercourse crossings will be required. Confirmation of the level of any CAR authorisations required for the new watwercourse
crossings will be confirmed with SEPA in advance.
The new crossing structures will not form a barrier to river flows (low flows and flood flows) and aquatic fauna, and will be designed and
constructed with respect to relevant guidance and best practice.
Where access tracks cross artificial drainage ditches, simple pipe structures will be installed in accordance with the Forests and Water
guidance document. The pipe invert levels will be installed slightly below upstream and downstream bed levels to ensure that barriers
for fish passage and sediment transport are minimised.
Streams, crossings and drainage ditches will be inspected and cleared regularly to prevent blockages and remove the risk of flooding
throughout the construction and operational life of the wind farm.
On-Site Buildings
On-site welfare facilities will be adequately designed and maintained to ensure all wastewater and sewage is disposed of appropriately.
Rainfall on roofs will be collected in a rainwater tank for re-use within the building. Any excess rainwater will be discharged to
groundwater or surface water.
Cables
Where cables are required to be buried, the following mitigation shall be put in place:
• Excavations for trenches will be of minimal size necessary to undertake works;
• Cable trenches will be dug, cables laid and filled in sections to minimise the areas of active excavation open at any one time;
• Bunds will be placed along the route of the buried cable route to prevent the creation of a preferential pathway for groundwater
arising along the path of the cable; and
• All cables will be marked above and below ground to ensure there is no danger to human health or the environment during
maintenance or earth works within the vicinity of the cable routes.
