The River Ehen is designated as a European Special Area of Conservation (SAC) and Site of Special Scientific Interest designated for Freshwater Pearl Mussels which need a healthy population of Atlantic Salmon.
The salmon (carrying the Freshwater Pearl Mussels) use the last stretch of the river Ehen, which passes through Greenmoorside enroute to the sea.
Sounds magical – because it is. Greenmoorside is also a flood plain for the River Ehen.
Although it flows out of Ennerdale Water, the River Ehen belongs equally to the west Cumbrian plains, forming the boundary between the mountains and the plains for most of its course.
At least one borehole is on the River Ehen flood plain – as described by NuGEN’s contracter RIZZO…..
RIZZO understands that BH13 is on the floodplain of the nearby River Ehen and may be difficult to access. This borehole is required to investigate postulated Fault “E” and must be completed. Minor adjustments will be considered, depending on the exact location of the Fault as determined by the geophysical survey.
For pricing purposes, assume that drilling mud/water must be captured and stored on-site until it has been tested for contamination. Contamination testing will be performed by RIZZO or NuGen. Following contamination testing, drilling mud/water is to be disposed in accordance with Environmental Agency (EA) regulations. Should the drilling mud/water be found to be contaminated, this will constitute a Changed Condition and additional
consideration will be given for disposal, or disposal will be handled by RIZZO and/or
