## Summary

The procurement process for the contract titled "Welsh Potosi - Esgair Ffriath Surface Water Management" was initiated by the Mining Remediation Authority, a central government public authority located in Nottinghamshire, United Kingdom. The project focuses on addressing river pollution and restoring river health affected by historic metal mining at the Esgair Ffriath mine site, approximately 8.7km east of Tal-y-Bont, Ceredigion. The procurement has progressed to the Award stage as of 2nd June 2026, following a limited competition procurement method. The contract is set for completion by 31st December 2026, with the possibility of extension due to weather and site conditions.

This procurement offers significant opportunities for businesses specializing in environmental services, particularly those aimed at surface water pollution protection. Given the focus on scour protection measures and site drainage modifications, companies with expertise in environmental engineering and construction could benefit from engaging in such projects. Small and medium enterprises (SMEs) like MIDWEST PLANT LIMITED, which has been awarded the contract, illustrate the suitability of similar-sized firms to successfully compete and grow by providing services to sensitive ecological and heritage sites that require careful management and compliance with environmental protection standards.

## Notice

The Welsh Potosi project forms part of a wider programme delivered by the Wales Metal Mine Programme (WMMP), with the objective of reducing river pollution and restoring river health affected by historic metal mining. The Welsh Potosi Project comprises two mine sites - Esgair Hir and Esgair Ffriath. The works described here are located on the Esgair Ffriath mine site. Esgair Ffriath is located approximately 8.7km east of Tal-y-Bont, Ceredigion. To address the impacts of legacy mining at Esgair Ffriath, it is proposed to construct scour protection measures, modify site drainage, and erect new fencing. The primary driver for the proposed works is to keep clean water clean and reduce the mobilisation of metal-rich sediment from the former Esgair Ffriath dressing floor into the receiving watercourses of the Nant Du and Afon Lluestgota, thereby reducing impacts on the Nant-y-Moch Reservoir and ultimately the River Rheidol. The site is in an area of sensitive ecology and heritage and so measures to protect this will be incorporated into this scope and the accompany Environmental Action Plan (EAP). The site is designated as the Mwyngloddfeydd Esgair Hir ac Esgair Ffraith Mine Site of Special Scientific Interest (SSSI) and Regionally Important Geodiversity Sites (RIGS). This SSSI is designated for its assemblage of lichens associated with metal-rich habitats (metallophyte lichens); an exceptionally rich assemblage of ferns and related plants (pteridophytes); and the rare metallophyte liverwort Copperwort. The site is of archaeological significance and contains numerous heritage features associated with historic mining activity, including the former dressing floor, engine pits, shafts and adits.
