Project description

Ribble Link Dredging
The Canal & River Trust have a statutory duty to maintain navigational depth along the Ribble Link canal for the purpose of the safe passage of canal boats for recreational use. To achieve this the canal is dredged each year by our term contractors Land and Water Services. The lower end of this canal is below MHWS. The dredging within the tidal stretch is carried out between E:348181 N: 430152 and the location of the “overhead pipe bridge” at E:347833 N:430015. The stretch we dredge below MHWS is 0.5km in length. Sediment accumulates in this stretch that requires dredging annually because it is washed over the sea lock gates on the tide. This spot dredge has been carried out in the same way annually for the past 12 years.
The sedment is sampled and analysed annually in advance of the work. The sediment from the tidal stretch has been removed from the channel and taken for off-site disposal at a nearby non-hazardous landfill for the past 12 years. The material we remove each year is sampled and has no contamination issues. This application is for the material to be taken off-site for disposal each campaign. If the end disposal of the material was to change then another application would be submitted. Please see attached sediment analysis results (Sample 8 is within the tidal section of the canal)

This spot dredging is undertaken on an annual basis. The spot dredging is always undertaken in the winter months (January - April). The dredging within the tidal stretch takes 1 month to complete each year and no more than 3000m3 of material is removed each campaign. This application is to cover dredging for 1 month per year in the tidal stretch between the months of January - April.
