This study aimed to identify the water quality benefits of remediating two coal mine discharges, one in Scotland and one in Northern England. For each site, the assessment followed the updated coal methodology (RPA, 2015). The first stage involved the development of assumptions for the assessment, setting out key points such as the length of waterbody affected, the likely extent of the improvement in water quality, and whether this improvement would be sufficient to result in a status change under the Water Framework Directive (WFD).

This work for the Coal Authority involved assessing the benefits of remediating three former mining areas. All three sites (two in Scotland, one in England) had previously been used for metal mining. This meant that the mine water discharges, along with any runoff from nearby spoil heaps, had high concentrations of metals such as zinc, lead and cadmium. This metal rich water was affecting water quality and the classification of waterbodies under the Water Framework Directive (WFD).

The EU Green Infrastructure Strategy adopted in May 2013 foresees a number of actions to be carried out under the lead of the European Commission in the following years. They include, for example, integrating green infrastructure (GI) into key policy areas, improving the knowledge base and encouraging innovation in relation to GI, and assessing opportunities for developing a trans-European GI network (TEN-G).

RPA is assisting Work Group 5 of the International Aerospace Environmental Group (IAEG) with an ongoing set of studies to map the supply chain for multiple compounds of concern used in the aerospace sector. The core aim of each study is to allow IAEG WG5 to understand the potential impact on the aerospace industry and its supply chain from a particular REACH Annex XIV listing, as well as the broader market for the substance(s) being assessed. These outputs may be used to formulate decisions and feed into any potential future REACH Authorisation activities.
