Results of botanical survey of translocated Phase 3.1 material July 2018 Bioscan UK Limited E1297R5 3 Long Drowpits Inert Landfill: Revised Phase 2 and 3 Restoration and Mitigation Strategy to accompany extension of time application 1 BACKGROUND 1.1 Planning context 1.1.1 Barton Plant operate an inert landfill facility at the Boughton Estate, near Kettering, Northamptonshire (approximate site centre SP878814) pursuant to planning permissions 12/00068/WASVOC, 08/00081/WAS and 08/00082/WAS. 1.1.2 The permissions cover the linked infilling and restoration of a worked out ironstone gullet partially restored in the past to a shallow east-west type valley landform. The concave void space created is being infilled with inert materials and restored to convex profile, working from west to east. Phase 1 was completed previously and is not relevant to the current permissions. Final restoration of the infilled Phase 2 area is being achieved in stages using materials derived from advance preparation of the westernmost Phase 3 extension (Phase 3.1) prior to landfilling there. The extent of the Phase 2 and Phase 3 areas of the site is shown at Figure 1. 1.1.3 In 2010, an Ecological Management Plan (EMP) was submitted to the Waste Planning Authority pursuant to condition 13 of permission 08/00082/WAS, and subsequently approved. The EMP covered restoration and mitigation requirements for both the Phase 2 and Phase 3 areas. It also set out strategies to mitigate for possible effects on protected great crested newts and common reptile species (principally common lizard). These measures were subsequently put into practice over the course of 2012 and since. The works in respect of great crested newts, and the ongoing measures to prevent them coming into conflict with the operational activities, have been carried out under the terms of a derogation licence number EPSM 2011-3359(D) issued by Natural England, and subsequent versions of this licence (current ref 2017-32664-EPS-MIT). Exclusion fencing maintains the Phase 2 and Phase 3 areas clear of any constraint imposed by these protected species. 1.1.4 In 2013 and 2014, revisions to the EMP were submitted to and ultimately approved by the Waste Planning Authority (WPA) to address changes brought about by the slowing of landfilling operations during the economic downturn and the resultant need to extend the timetable for completion of restoration. 1.1.5 Progress on infilling and restoration has continued to be retarded by ongoing economic factors and a further application is therefore being made to vary the conditions pertaining to timescales for completion of restoration of Phases 2 and 3 and specifically to extend the end date from December 2019 to the end of 2024. 1.1.6 Northants County Council, as Waste Planning Authority, have requested that a revised EMP be submitted with the application to reflect this change in timescale, and also to reflect the position on the ground viz a viz progress on restoration to date.
