<p>The Airports National Policy Statement sets an expectation that, in addition to
controlling and reducing aircraft noise impacts, an applicant for development consent
for a Northwest Runway at Heathrow Airport will be required to commit appropriate
resources to mitigate the impacts of aircraft through noise insulation programmes
for both private homes and public buildings.</p><p> </p><p>It notes that Heathrow
Airport Ltd (HAL) has publicly committed, following third party assessments, to provide
full acoustic insulation for residential property within the full single mode easterly
and westerly 60dB LAeq (16hr) noise contour of an expanded airport; and to provide
a contribution of up to £3,000 for acoustic insulation for residential properties
within the full single mode easterly and westerly 57dB LAeq (16hr) or the full 55dB
Lden noise contours of an expanded airport, whichever is the bigger. In addition,
HAL has committed to deliver a programme of noise insulation and ventilation for schools
and community buildings within the 60dB LAeq (16hr) contour.</p><p> </p><p>The geographical
areas that the scheme could cover is dependent on flight paths for an expanded Heathrow
Airport. Preparations for the airspace change process are complex and will take some
years to work through.</p><p> </p><p>In considering the case for expansion the Department
commissioned a review of strategies adopted by international airports to mitigate
the impact of airports on residents. In considering the scheme proposed by HAL the
review found the schemes to be comparable to those on offer in other countries.</p><p>
