The Ffos-y-fran Land Reclamation Scheme was a major opencast coaling operation to the north-east of Merthyr Tydfil in South Wales.
Phases I 'Incline Top' and II the Dowlais 'Great White Tip'[10] of the scheme were completed in 1993 and 1997 respectively, restoring 106 ha of derelict land to provide residential, light industrial and recreational uses.
Protesters said that if the scheme proceeded, it would mean work taking place just a few hundred metres away from homes in the villages of Dowlais, Mountain Hare, and Penydarren; some houses would be less than 40 m from the boundary of the site.
In February 2005 the Welsh Assembly approved the Ffos-y-Fran scheme, but the High Court quashed the decision after it was claimed by local residents that Environment Minister Carwyn Jones had made his mind up before the planning committee met.
Mr Jones denied the claim and the Welsh Assembly took the case to appeal judges, who gave final approval of the scheme on 27 November 2006.
Built in 1959 on land to the north and east of the railway connection to Fochriw Colliery, the coal washery was refurbished by Celtic Energy in 1992.
The facility was built to meet demand for high quality Welsh coal by the Tata steel works site in Port Talbot.
