Introduction Background to the Project 1.1 AECOM has been appointed by the East Northamptonshire District Council to assist in producing a report to inform the councils Habitats Regulations Assessment (HRA) of the potential effects of East Northamptonshire Local Plan on the Natura 2000 Network and Ramsar sites. The objectives of the assessment are to: • Identify any aspects of the Local Plan that would cause an adverse effect on the integrity of Natura 2000 sites, otherwise known as European sites (Special Areas of Conservation (SACs), Special Protection Areas (SPAs), protected SPAs (pSPAs) and, as a matter of Government policy, Ramsar sites), either alone or in combination with other plans and projects; and • To advise on appropriate policy mechanisms for delivering mitigation where such effects were identified. 1.2 The HRA of the East Northamptonshire Local Plan is required to determine if there are any realistic linking pathways present between a European site and the Local Plan and where Likely Significant Effects cannot be screened out, an analysis to inform Appropriate Assessment to be undertaken to determine if adverse effects on the integrity of the European sites will occur as a result of the Local Plan alone or in combination. Legislation 1.3 The need for HRA is set out within the Conservation of Habitats & Species Regulations 2017 (Box 1). European sites (also called Natura 2000 sites) can be defined as actual or proposed/candidate Special Areas of Conservation (SAC) or Special Protection Areas (SPA). It is also Government policy for sites designated under the Convention on Wetlands of International Importance (Ramsar sites) to be treated as having equivalent status to Natura 2000 sites. Box 1: The legislative basis for Appropriate Assessment Conservation of Habitats and Species Regulations 2017 (as amended) The Regulations state that: “A competent authority, before deciding to … give any consent for a plan or project which is likely to have a significant effect on a European site … must make an appropriate assessment of the implications for the plan or project in view of that site’s conservation objectives… The competent authority may agree to
