In parallel with this, the Issues and Options DPDs of three other Councils in South Hertfordshire (Dacorum Borough Council, Three Rivers District Council and Watford Borough Council) were also subjected to Appropriate Assessment screening, the outcome of which is presented in separate reports, one for each council. Appropriate Assessment screening is required where any plan, alone or ‘in combination’ with other plans, could have an adverse affect on the integrity of Natura 2000 Site (i.e. Special Protection Areas (SPAs) and Special Area of Conservation (SACs)) following Article 6(3) of the European Habitats Directive, and therefore determines whether a full Appropriate Assessment is required. The first phase of this screening involved an analysis of St Albans Core Strategy Issues and Options DPD and St Albans City and District/ Dacorum Borough Councils’ Core Strategies Supplementary Issues and Options Paper: ‘Growth at Hemel Hempstead’ to ascertain any likely significant effects that may compromise the conservation objectives of nearby Natura 2000 sites. In agreement with Natural England, the statutory consultee for AA screening, it was decided that Chilterns Beechwoods SAC is the only site of relevance to this screening. The next phase of the AA screening involved examining all other plans, programmes and projects that may affect the Chilterns Beechwoods SAC in conjunction with the St Albans Issues and Options. This included the Issues and Options DPDs of neighbouring councils, including Dacorum Borough Council, Three Rivers District Council and Watford Borough Council, and regional planning documents. The screening process concluded, in agreement with Natural England, that any likely potential impacts of the St Albans Issues and Options (including the combined Dacorum/ St Albans Issues and Options for Hemel Hempstead growth), either alone or in combination with other plans and programmes, are not considered to be significant, providing that Option 21(c) in the St Alban’s Issues Doc No 1 Rev: 3 Date: April 2008 St Albans City & District Council Issues & Options AA Screening 1 and Options is only pursued under certain circumstances. Mitigation measures were nevertheless recommended as being necessary if these options were pursued. These would need to be agreed with Natural England and could also be used as best practice to limit recreational pressure on Chilterns Beechwoods SAC even if the above options were not pursued. In light of the assessment it was concluded that it would not be necessary to undertake a full Appropriate Assessment on the St Albans Core Strategy Issues and Options DPDs.
