Parc Slip Colliery was a coal mine near situated at Aberkenfig, near Tondu in Bridgend County Borough, Wales.
After mining ceased in 2008, a series of legal cases were undertaken by both Bridgend County Borough Council and the Welsh Assembly Government against Celtic Energy.
This culminated in 2013 with the Serious Fraud Office bringing charges against two former directors of Celtic Energy and four other individuals, who it was alleged had conspired to move the ownership of Parc Slip and five other sites to companies registered in the British Virgin Islands, to avoid the costs of land restoration.
[3] In 2016, in light of the large scale flood within the former opencast workings, Celtic Energy proposed an alternative restoration scheme to Bridgend County Council.
[4] Accepted by the Council, the site is now a nature reserve with a mix of habitats including grassland, woodland and wetlands, which is managed by the Wildlife Trust of South and West Wales.
