Description

In 2011, the Water and Abandoned Metal Mines (WAMM) Programme was set up between the Environment Agency, Defra and the Coal Authority to address pollution of rivers by abandoned metal mines. Currently, the Coal Authority operates four WAMM mine water treatment schemes, each using a different treatment technology, which are improving water quality in about 20 km of rivers. In January 2023, Parliament adopted a statutory metal mines target, under the Environment Act 2021, to halve the length of English rivers polluted by harmful metals from abandoned metal mines by 2038. The Government's Environmental Improvement Plan (EIP), published in January 2023, estimated that to achieve this long-term target would likely require around 40 new mine water treatment schemes and a similar number of diffuse interventions. The EIP set a non-statutory interim target to construct 8 mine water treatment schemes and 20 diffuse interventions by 31 January 2028. To help deliver the interim and long-term targets, the WAMM Programme is currently investigating active treatment options for mine water discharging from abandoned metal mines by undertaking active treatment trials on up to five sites This opportunity is now open with a submission deadline of 29 October 2024 All interested parties are advised to visit each site to familiarise themselves with the sites layout, limitations, restrictions and access. Visits to the premises must be made by appointment only with the Coal Authority . There is limited parking at each site, interested parties shall only attend at the agreed time provided by the Client.
