+ | Where the current licence does not permit the use of erosion control matting, Able wish to vary the licence in order to add the erosion control matting to the existing licence. | ||
+ | To support this update, I have appended a document which outlines the summary of changes and provides a review of the original HRA assessment. | ||
+ | Amend the existing coordinates on the main licence for 'Able Seaton Port, Quays 10 and 11' as there is an error. Additional coordinate has been provided. No areas outside existing ' | ||
+ | The area included within the revised coordinate was also assessed in the original HRA. | ||
+ | === Why would you like to vary your licence(s)/ | ||
+ | We are proposing to carry out capital and maintenance dredging at Quay 10 and 11 at Seaton Port. This will include dredging at the eastern end adjacent to land fronting the Power Station. This request is to have the ability to install erosion control matting over the area of the berth where slopes will form from dredging activities. This is to protect the land adjacent to the berth from erosion impacts. | ||

+ | === What would you like to vary about your current licence(s)/ | ||
+ | The existing Seaton Port Approach Channel is proposed to be widened from 85m to 100m and this will involve the capital dredging of around 75,000m3 of clay and silt material. Therefore the changes to the licence will include the following: | ||
+ | - Amendment to Marine Licence Schedule 3, which will consist of updating the coordinates for the site " | ||
+ | - Amendment to Activity 1.2, which will consist of updating the quantities to include an additional 145,000m3 of material. | ||
+ | - To include an -0.5m over-Dredge allowance for each dredging activity | ||
+ | (the total volumes will not change) | ||
+ | Please see attached Covering Letter for further information. | ||
+ | === Why would you like to vary your licence(s)/ | ||
+ | Currently, access to ASP is constrained by virtue of the approach which requires vessels to navigate along a 120m wide channel that is dredged to -6.5m CD within which lies an 85m wide channel, dredged to a depth of -9.5m CD. Buoys mark the shallower 120m wide channel, whilst the 85m channel is unmarked. ABLE proposes to develop the site by widening the 85m channel by 15m to provide a 100m channel dredged to -9.5m CD. The Buoys could then be relocated to mark the deeper channel. This would enable a wider range of vessels associated with OWF development to access the facility. | ||

+ | 1) Incorrect Coordinates | ||
+ | |||
+ | Upon review, 6no coordinates on Licence Schedules (Able Seaton Port Holding basin and Channel) are to be amended correctly. | ||
+ | |||
+ | Historically Seaton Channel has been dredged to a depth of up to - 5.8mCD and a width of up to 164m. Seaton Channel joins the River Tees at a location that is maintained by PD Ports at -11.7mCD (refer to Admiralty Chart for Tees and Hartlepool Bays). The intersection between Seaton Channel and the River Tees is formed by a slope falling (at around 1:3) from Seaton Channel to the River Tees. See attached drawing ASC002-00003 where the slope has been annotated. One of the original objectives of the MLA was to obtain consent for lowering Seaton Channel to -9.5mCD over a width of 85m up to its intersection with the River Tees. | ||
+ | |||
+ | The coordinates for Seaton Channel in the original MLA were specified at the top of the slope connecting Seaton Channel to the River Tees. The substitute coordinates submitted in Variation 10 amends the coordinates so that they are located at the bottom of the slope. | ||
+ | See attached of PDF table | ||
+ | |||
+ | 2) Incorrect Quantities | ||
+ | |||
+ | Following a review of the Marine licence we request the following nonmaterial corrections in addition to the coordinate corrections: | ||
+ | - Due to historic errors, the disposal tonnages are not consistent with the dredge volumes. In particular: a.V3 of the Licence permitted 1,212,000 wet tonnes of clay to be deposited but this have been 1.221,000T (555, | ||
+ | - We request a change to the volumes provided in Activity 1.2 as the volumes of silt and clay have been wrongly transposed from V6 of the Licence and both were incorrectly identified as silt in V7. | ||
+ | - We request that where annual volumes are specifically stated for Site 2, these volumes can be carried over to subsequent years as dredging may not occur every year but silt will still accumulate. | ||
+ | - V8 allowed for Seaton Channel to be widened and a consequential additional capital dredge of 145,000m3 . We advised that this would be silts and clays. All of the material is expected to be dredged by BHD and will comprise silts/soft clays and stiff clay. We propose amending Activity 1.1 so that the whole of the additional dredging is classed as clay and that Activity 4.1 is amended to permit the anticipated 50,000m3 of silts/soft clays to be deposited in Tees Bay A. | ||
+ | - A number of dredging methods are consented within the Licence but Activity 1.1 only describes backhoe dredging, we request that the methodology is extended to include TSHD which is consented for other Activities. | ||
+ | - We request a change to the text describing the methodology of Activity 2.1 to remove reference to 30,000T of clay which is not in any event listed in the quantities for that Activity. | ||
+ | - We request that Activity 2.3 is split into two Activities, one covering the capital works and the other the maintenance works. | ||
+ | - We request changes to the description and methodology of Activities 3.1 and 4.1 to remove inconsistencies in the current wording. | ||
+ | - We request corrections to the description of the source of material specified in Activity 3.1 and 4.1 | ||
+ | |||
+ | All of our proposed textual changes to the Licence are included in the attached WORD document with the changes tracked for transparency. | ||

+ | === Why would you like to vary your licence(s)/ | ||
+ | The work is essential to accommodate a new installation vessel (already chartered) that will collect offshore wind turbines from ASP. As the installation is planned to commence in April 2023, dredging is required as a matter of urgency to allow the installation vessel to load-out the wind turbines from the quay (where they are being stored) for onward transport and installation at the offshore windfarm site (Dogger Bank A, B and C). To load out the turbines, the installation vessel must jack up from the sea-bed and its jack up feet must bear onto level ground. As existing, the feet will straddle an area dredged to -9.5m CD and an area dredged to -13.5m CD. Failure to load out the turbines will cause the whole project to be jeopardised. The extent of the proposed dredging is insignificant, | ||
+ | The area of the extension is sited within a previously dredged area and adjacent to the area dredged in January 2023. Extensive maintenance sampling in this location has been undertaken and approved previously by the MMO to allow for undisrupted dredging activities. | ||
+ | Notably, the Dogger Bank project is one of the largest projects of its kind in the world, and of great importance to the UK’s long-term national energy security (powering 6 million British homes).
