Aviation Policy Framework metrics and DfT revised NPS noise analysis

Angela Baker made this Freedom of Information request to Civil Aviation Authority

This request has been closed to new correspondence from the public body. Contact us if you think it ought be re-opened.

The request was partially successful.

Dear Civil Aviation Authority,

Regarding the Department for Transport’s revised aviation NPS for the Heathrow NWR expansion proposal and noise impact supplement (including its Appraisal of Sustainability), please provide any meeting minutes, board papers, research or discussion papers or emails discussing further analysis of noise impacts as compared to the original NPS and its supplements by the CAA and any other relevant parties. This request covers discussions on whether to include any of the new suite of noise metrics as published in the DfT’s revised ‘Aviation Policy Framework’ in any further analysis for the revised NPS and why the wider suite of metrics now proposed for adoption as national policy should or should not be used for NPS noise analysis. ( for example include assessment of numbers affected at 51 dBLAeq, numbers of daytime noise events above 65 dBLAmax and noise analysis on a single operation mode.)

Yours faithfully,

Angela Baker

Dear FOI Requests,

Thank-you for the information that you provided. However, there seems to be some information still missing which has been alluded to in the correspondence that you have already provided.

Further to my original request and in light of what information has been provided so far, will you please provide the missing details as outlined below:

1. CAA email 07/08/17 states that SONA report confirms 54 DbLeq as the new 57 and that DfT proposed monetisation down to 51. However it doesn't say whether the monetisation values were updated as a result of adoption of the new standard. The email does acknowledge that the assessment areas approximately doubles between 51 and 54 dB. So where is the assessment of this change and details on how many people fall within the 51 dBLeq LOEL? CAA must have some analysis on this.

2. CAA's email 08/08/17 confirms he (someone from CAA) had advised against putting a line on a map showing 51 day and 45 night stating 'it had not been done before'. On the same day the DfT states it is 'happy to go with what you advise and not produce contour maps for 51 and 45 dB'. Was DEFRA or Dept of Health/PHE involved at all in these decisions? Is there further correspondence to show how this policy was confirmed procedurally?

3. CAA email 14/09/17 refers to 'Respite' and 'Minimise New' scenarios but says they had been dropped as the 'number of scenarios was too high to complete by the end of August'. Where is the correspondence on a formal agreement to this, particularly who from the DfT agreed and were DEFRA or DoH/PHE consulted, any correspondence with these departments agreeing to limited modelled scenario?

Yours sincerely,

Angela Baker
