Noise contour limits and quota count point limits
33.—(1) The area enclosed by the 54dB LAeq(16hr) (07:00-23:00 hrs) and the 48dB LAeq(8hr) (23:00-07:00hrs) contours shall not exceed the limit values for the time periods set out in Table 1. The contours shall be calculated using the Federal Aviation Authority Aviation Environmental Design Tool noise model version 3e prepared to support the DCO submission or periodic updates to that model, subject to written agreement from the ESG.

|---|---|---|---|---|---|
| Period | Up to 2028 | 2039-2033 | 2034-2038 | 2039-2043 | 2044 onwards (in 5 year cycles) |
| Average summer day-time noise levels, as measured by size (km2) of 54 dB LAeq, 16hr noise contour | 31.3 | 30.4 | 29.6 | 32.6 | 32.6 |
| Average summer night-time noise levels, as measured by size (km2) of 48 dB LAeq, 8hr noise contour | 42.6 | 41.5 | 39.7 | 43.2 | 43.2 |
(2) The contour area limit values shall be converted to day and night quota count budgets, supported by threshold value day and night quota count budgets as set out in the GCG framework, using a regression analysis approach to be agreed with Luton Borough Council in consultation with the specified authorities.
(3) The undertaker must comply with the contour limit values set out for the time periods indicated. Where the airport is operated in excess of the contour limit values, it is not a breach of the terms of this Order for the purposes of Part 8 of the 2008 Act if the exceedance is due to action taken in emergency circumstances in which there was reasonably reasonably cause for apprehending injury to persons or serious damage to property.
