(2) The authorised development must be operated in accordance with the noise mitigation plan.
(3) No part of the authorised development is to commence until the measures set out in sections 2, 3, 4, 5 and 9 of the noise mitigation plan have been implemented.
(4) Residential properties with habitable rooms within the 60dB LAeq (16 hour) day time contour will be eligible for noise insulation and ventilation as detailed in the noise mitigation plan.
(5) The airport will be subject to an annual noise quota of 2000 between the hours of 06.00 and 07.00 as set out in paragraph 1.8 of the noise mitigation plan.
(6) Any aircraft which has a quota count of 4 or above cannot be scheduled to take-off or land at the airport between the hours of 06.00 and 07.00 as set out in paragraph 1.7 of the noise mitigation plan.
(7) The area enclosed by the 50dB(A) Leq16hr (07.00 to 23.00) contour must not exceed 35.8 sq km, and the area enclosed by the 40dB(A) Leq8hr (23.00 to 07.00) contour must not exceed 47.4 sq km as set out in paragraph 1.12 of the noise mitigation plan.
(8) In this requirement—
“LAeq (16 hour) day time contour” means the equivalent continuous sound level of aircraft noise during the average day; and
“quota count” means the amount of the quota assigned to one take-off or landing by the aircraft in question.
