The Woodsmith Project - S73 Project Amendments : Planning Statement

Two wastewater and two fire/service water storage tanks will be located within a common bunded area. The wastewater tanks will be 11m diameter x 6.5m high with a capacity of 570m3. Periodic discharge of the wastewater is required via road-going tanker to be disposed of off-site at a suitably licensed facility. The wastewater unloading area incorporates a concrete bunded truck bay which falls to the main tank bunded area sump in case of any spillage. The Fire/Service Water tanks will be 7m diameter x 3.2m high with a capacity of 120m3. They are sized to meet the water demand of two fire hydrants running simultaneously for 60 mins, with an additional 10m3 of available volume of service water. A self-contained pumphouse will be located in the water storage area, which contains an electric main pump and jockey pump, with a diesel back-up incorporated into a 20ft container sized skid. A surface fire water system including concrete bunding, tanks (2 x 7m diameter x 3.2m high), pump house, fire ring main, hydrants, etc. will be installed for construction and operational purposes.

Surface Water Drainage

During construction, all surface water within the construction site is routed through oily water separators to the construction attenuation pond and, where necessary, treated via a surface water treatment plant, prior to discharge to Lockwood Beck providing attenuation for a 1 in 20-year storm event. During operation, when the platform area reduces, the site will continue to utilise the existing oily water separators, attenuation pond and discharge point, providing attenuation for a 1 in 100-year storm event plus 45% allowance for climate change.

Landscaping and Earthworks

No changes to the current arrangements at Lockwood Beck are proposed during the construction phase.

4.94

In operation, the topography of the site, where altered during construction, will be returned to the original elevations, except for the platform surrounding the headhouse. The wider construction platform will be removed and the area profiled and rehabilitated, to create screening for low level lighting and vehicle movements on the platform. The wider land holding area outside the operational platform will be subject to ongoing habitat/biodiversity enhancement, including areas of grassland, scrub and trees.

Tocketts Lythe MTS Site

No development will occur at Tocketts Lythe. This means that there will be no construction traffic or on-site activity and no shaft sinking, including removal of the requirement for a 45m high winding tower. This would also result in the removal of the planned earthworks for extractive waste management facilities, land forming and associated surface water management
