Air Quality Reviews DEFRA say must be seen within the context of other local and National Issues like the Climate Emergency
SOCS, the North Fringe Protection Group & others suggest that proposed changes to Ipswich's Local Air Quality Management Areas (LAQMA) should be postponed until more consistent and fuller measured data is available.
We quote from DEFRA;
https://laqm.defra.gov.uk/review-and-assessment/declare-or-revoke-aqmas/revoking-aqma.html
'The decision to revoke an AQMA should only be taken following a Detailed Assessment or Further Assessment. This should set out in detail all the available information used to reach the decision. In some instances if compelling evidence exists, an AQMA can be revoked following an Updating and Screening Assessment or Progress Report.
Pollutant concentrations may vary significantly from one year to the next, due to the influence of meteorological conditions, and it is important that authorities avoid cycling between declaring, revoking and declaring again, due simply to these variations.
Before revoking an AQMA on the basis of measured pollutant concentrations, the authority therefore needs to be reasonably certain that any future exceedences (that might occur in more adverse meteorological conditions) are unlikely.
For this reason, it is expected that authorities will need to consider measurements carried out over several years or more, national trends in emissions, as well as local factors that may affect the AQMA, including measures introduced as part of the Action Plan, together with information from national monitoring on high and low pollution years.'
