Paragraph 18 Receptor-based noise mitigationI1
England and Wales
Within not more than 3 months following the commencement of any of Work Nos. 1 – 7 (inclusive) or 18 (replacement western noise mitigation bund), the undertaker is to submit for approval to the relevant local planning authority—
a list of premises forecast to be potentially eligible premises at or after the commencement of dual runway operations (using the most recent available forecast at that time); and
details of how the provision of a package of receptor-based noise mitigation measures is to be promoted to those potentially eligible premises and how an owner (or occupier with the owner’s prior written consent) of such premises may apply for such a package.
Within not more than 3 months following the approval of the list and details in sub-paragraph (1), the undertaker must take the steps approved under sub-paragraph (1)(b) to notify the owners and occupiers of all eligible premises that the premises are eligible for the design and installation of a package of F1receptor-based mitigation measures.
The undertaker must submit for approval by the relevant local planning authority details of the specific receptor-based mitigation measures for each eligible non-residential premises and the details submitted to the relevant planning authority must be—
reasonably expected to achieve the standards set out in section (c) of the noise insulation scheme document; and
comprised of measures selected from the list set out in section (d) of the noise insulation scheme document.
The maximum sums of money to be provided by the undertaker towards the package of receptor-based mitigation measures for eligible residential premises are as follows (plus VAT)—
inner zone - no limit;
outer zone 1 - £6,500; and
outer zone 2 - £4,500.
The maximum sum of money to be provided by the undertaker towards the package of receptor-based mitigation measures for F2eligible non-residential premises is £250,000 (plus VAT) per applicant, per building or group of buildings in the same occupation and location.
Within not more than—
12 months (for eligible premises F3within the the inner zone); or
24 months (for eligible premises F4within outer zone 1 or outer zone 2),
of receipt of a valid application for receptor-based mitigation measures from an owner (or occupier with the owner’s prior written consent) of eligible premises, the undertaker must, subject to access being granted to the premises, carry out a survey of those premises and submit for the agreement of the owner a specific package of receptor-based mitigation measures proposed to be installed at those premises.
In terms of F5eligible residential premises within the inner zone, the provision of a package of receptor-based noise mitigations is to include a dynamic thermal modelling report undertaken in line with the requirements set out in in the Chartered Institution of Building Services Engineer’s TM59: “Design methodology for the assessment of overheating risk in homes” (2017) or any later version.
The specific package submitted under sub-paragraph (6) must be F6...—
F7for eligible residential premises, reasonably expected to achieve the standard set out in section (a) of the noise insulation scheme document and comprised of measures selected from the list set out in section (b) of the noise insulation scheme document; or
for eligible non-residential premises, in accordance with the specific package approved pursuant to sub-paragraph (3).
The undertaker is not obliged by anything in this requirement to install any receptor-based mitigation measures that are declined by an owner of eligible premises.
Where any eligible premises is a listed building, the undertaker is to submit (at the cost of the undertaker) the necessary application for the required consents following any requirements of the local conservation officer and Historic England’s guidance Energy Efficiency and Historic Buildings, Secondary Glazing for Windows, 2016 (or successor guidance).
If—
a relevant local planning authority refuses to approve the list of premises or promotion details pursuant to sub-paragraph (1) or fails to communicate a decision F8within 8 weeks of the submission of the list and/or details by the undertaker;
a relevant local planning authority refuses to approve details of the specific receptor-based mitigation measures pursuant to sub-paragraph (3) or fails to communicate a decision within 8 weeks of the submission of the details by the undertaker; or
an owner rejects the specific package of receptor-based mitigation measures proposed by the undertaker pursuant to sub-paragraph (6) on the basis that they consider that the package does not comply with sub-paragraph (7),
the undertaker, the relevant local planning authority or the owner (as relevant) may refer the matter to the noise F9insulation scheme independent panel.
Upon a referral pursuant to sub-paragraph (11), the noise F10insulation scheme independent panel may—
make a decision to approve details in place of the relevant local authority pursuant to sub-paragraph (1) or (3); or
confirm that the package of measures proposed to an owner pursuant to sub-paragraph (6) complies with F11sub-paragraph (8) or otherwise specify a revised package of measures that complies with sub-paragraph (8) that the undertaker is to be required to submit to the owner.
Subject to—
a relevant owner or occupier having made a valid application to the undertaker not less than two years from the date on which they were notified of their eligibility for receptor-based noise mitigation measures under sub-paragraph (2);
agreement by the owner or occupier of the eligible premises to the specific package of measures pursuant to sub-paragraph (6); and
if the eligible premises is a listed building, the grant of the necessary consents not less than 12 months prior to the relevant event,
the agreed package of receptor-based mitigation measures F12is to be installed and commissioned before the later of the commencement of dual runway operations or the year in which the premises is forecast to be within the relevant contour that rendered it a potentially eligible premises (using the most recent available forecast at that time).
Subsequent to the commencement of dual runway operations and annually thereafter the undertaker and the relevant local planning authority are to carry out modelling and F13... to identify additional potentially eligible premises or adjustments to the specification of the measures provided, in the manner set out in section (e) and section (f) of the noise insulation scheme document. With regard to any such premises the undertaker must offer, design, install and commission a package of receptor-based mitigation measures that accords with the other provisions of this requirement as soon as reasonably practicable.
The undertaker must notify each owner or occupier of an eligible residential premises which is within the LAeq F1416 h 66 dB air noise contour (as modelled based on actual operations of the previous summer following the commencement of dual runway operations) of their eligibility to receive a payment covering estate agent fees up to 1% of the purchase price and stamp duty costs to be met in full and any other reasonable moving costs (such as removals and storage) when requested by the owner, subject always to such entitlement being strictly limited to one claim per F15eligible residential premises.
Any dispute as to the costs offered or sought under sub-paragraph (15) may be referred by the undertaker or the relevant homeowner to the noise insulation scheme independent panel, which can decide whether the amount offered or sought is compliant with that sub-paragraph.
