Update

Further consultation with the Borough Emergency Planner, County Council Emergency Planner and West Emergency Planner has been undertaken and officers have no further comments to make in respect of the proposal.

Attached to the Update Sheet is a colour copy of the map attached at Appendix 17 of the Agenda in the interests of clarity.

Following the receipt of further information from the HSE, refusal reason Number 1 has been amended to make reference to the UK’s Draft Nuclear National Policy Statement published by the Department of Energy and Climate Change. Whilst this document is subject to public consultation until 22 February 2010 it is still a material consideration.

Cllr Musson who is not available to attend the meeting due to other commitments gives the following comment:

'The committee can’t make a decision to approve this application – only the Secretary of State is able to do it.

Therefore I believe we should stick with the previous committee decision to approve and allow the Secretary of State to make the final decision. To refuse or defer will leave no options for development in Tadley which effectively means stagnation. It sends the wrong decision to business who are likely to avoid the area as will developers so the end result is that Tadley suffers.

If we are concerned about safety then we should look to the entire population that represent the additional population over the recommended population number. In the words of the HSE officers from our last meeting the Boundary Hall numbers “are totally insignificant” so I recommend we separate the two issues of safety and 1 of 3 planning and force the Secretary of State to look in to this and offer a solution that does not mean a stagnation of development in Tadley for an indefinite period.'

Further comment from Tadley Scout Group Chairman:

• That recent cold weather has shown how vulnerable the existing building is which was closed for a week due to frozen pipes. • Heating costs are high as the building has a single brick skin; • Decisions on repair are based on the fact that the building is now only temporary. • Members should confirm their previous decision to approve - nothing has changed from the HSE • A new provision would give the scout group a 21st century Scout headquarters, possible expansion in membership, and a new facility for youth activities in Tadley. • That both Tesco and Cala Home have been very supportive of the Scout Group by paying for the utility bills and major repairs, new boiler and roof repairs.

Officer comments regarding population status

It is important to point out that it is the current estimated population which is critical in the determination of the planning application on the Boundary Hall site, rather than the population at some point in the past. However as referenced within the Agenda, it emerged towards the end of 2009 (October approx) that the HSE had inaccurately represented the population growth within specific sectors (6 and 7) between 1995 and 2008. Sectors 6 and 7 are where the Boundary Hall site is located. The HSE originally stated (in July 2009) that the population had increased by over 200% between 1995 and 2008 within these sectors, however, having undertaken an internal review (Basingstoke Officers) of this information and following discussions with the HSE (following their own review), it appears that there was a significant flaw in the 1991 baseline data that HSE utilised in 1995 (undertaken by Atkins) to calculate this population growth. The review indicates that as a result of the inaccurate figures from 1995, that the population growth within these sectors was actually significantly less than the 200%+ referenced by the HSE. In fact the highest level of actual population growth in any part of the 3km distance band within these two sectors between 1991-2008 is estimated to be an increase of no more than 17%, as reported within the Agenda. The issue of the accuracy of the population around the site as it was back in 1991 was questioned by the Borough Council following the HSE’s submission on the Shyshack Lane appeal in 2009. Whilst the original Atkins Report was made available to the council in December 2008, it was only questioned once the level of population growth was quoted as an issue in the NII’s Appeal Statement. Prior to this, all focus of attention was on current and future population levels – the past was not seen as an issue. As current population levels had been broadly agreed, attention turned to the historic (Atkins) data (in September/October 2009). The data can be found in HSE’s critique of WS Atkins (1995) Report, received in December 2009 at Appendix 16 of the report.

Table L.1 of Appendix 16 shows that the Atkins report indicated that the total population (all around the site) within 2km of a point of origin within the AWE site 2 of 3 was 5,032 in 1995, with a further 8,046 people living between 2km and 3km of this point. With regard to sectors 6 and 7, the population with each of these 30degree sectors can vary according to the sector rotation applied. From the second part of Table L.1, which is based on a 25degree sector rotation, it can be seen that within Sector 6, 1,338 people were estimated to live within 2km of the point of origin, with a further 648 people in the 2km-3km distance band. Likewise, in Sector 7, 1,281 people were estimated to live within 2km of the point of origin, with a further 680 people in the 2km-3km distance band. The revised HSE population estimates for sectors 6 and 7 using a 25degree rotation at 1991 can be found in Figure L.3 of Appendix 16. The revised figures for Sector 6 are 2,527 (0-2km) and 2,528 (2-3km); and for Sector 7, 2,099 (0-2km) and 1,406 (2- 3km). With reference to the agent's letter of 4th December 2008, Council Officers agree with points 2, 3 and 4 within the ‘Population Thresholds’ section, regarding the inaccuracy of the historic Atkins data, the sensitivity of the HSE population constraints model and the different iterations of this model since 2008. They do not agree with the assertions made within this letter with regard to the current broad population levels in the critical sectors, and are unable to agree with the assertions regarding the interpretation of these population assessments and densities by HSE. HSE has responded to the points within the agent's letter, information which is attached to this Update sheet to clarify their position. Appended to the update is a response from the HSE to the agents letter (attached as appendix 14 to the main agenda). Amended Recommendation The application be REFUSED for the following reasons: 1. The application site is situated within the (0-3) km Detailed Emergency Planning Zone (DEPZ) surrounding the Aldermaston Atomic Weapons Establishment (AWE). The use of the DEPZ in this context, provides an area for development control consistent with the zone defined originally for emergency planning purposes. The proposed development, if allowed, would further contribute to a long term net positive increase in the extant residential population density within the DEPZ. Such a situation would potentially increase the overall risk to the public in the event of an off-site release of radioactive material following a significant plant fault. Furthermore, the proposed development would adversely impact upon the maintenance of a controlled low population zone around the AWE nuclear facility. A controlled low population zone serves to both mitigate against the consequences of an off-site release, and facilitates emergency preparedness which are key elements of the defence-in-depth philosophy adopted by the nuclear community worldwide. As such the proposal would be contrary to the requirements of Policies E1 and D5 of the Basingstoke and Deane Borough Local Plan 1996-2011, advice contained in Planning Policy Statement 23: Planning and Pollution Control and within Circular 04/00 - 'Planning Controls for Hazardous Substances' and the 's draft Nuclear National Policy Statement. 2. Refusal reason unchanged as per original report.
