The outer surface of the SDP has a bitumen-asbestos glass-fibre reinforced coating. In addition to the pipeline, the removal of a large concrete break-pressure tank, six concrete wash-out pits and six brick air-valve pits is also required.

• Removal of the entire terrestrial section of the SDP including wash-out pits, air valve pits, the break-pressure tank, cathodic protection, and the shore valve-house.

• Stockpiling of the SDP sections at the Mx Winfrith Site.
• Radiological monitoring and disposal of all demolition rubble at suitably licensed facilities.
• Reinstatement of the pipeline corridor.
