UK Coal - Measham

UK Coal - Measham

We were commissioned to carry out a flood risk assessment as part of wider EIA when UK Coal proposed to extract coal from their Minorca site at Measham using surface mining. The Gilwiskaw Brook and one of its tributaries crossed the site and formed part of the River Mease SAC. A surface water management plan was therefore also needed to make sure there were no detrimental impacts and meet stringent SAC demands.

Complex groundwater regimes gave rise to potentially problematic hydrological interactions. Changes in channel geometry and water levels had affected earlier information provided by the Environment Agency. A bridge deck crossing the Gilwiskaw Brook needed to be set at a higher level. We resolved these issues through modelling and by incorporating additional surface water attenuation and treatment areas into the water management plan.

Our FRA report complied with planning policy and met the additional requirements of the Environment Agency. Our flood envelope assessment was critiqued by an independent hydrologist working on behalf of a protest group who found the report to be “clear, concise and relevant” and the methodology “appropriate”.  The protest group subsequently raised no objections to the report.
