  12. Non-road mobile machinery during onsite construction of any phase of development, all non-road transportable industrial equipment or vehicles which are fitted with an internal diesel powered compression ignition engine between 37 and 560KW and not intended for transporting goods or passengers on roads are required to meet Stage IIIB of EU Directive 97/68/E and be NRMM registered. Such vehicles must be run on ultra low sulphur diesel (also known as ULSD ‘cleaner diesel’ or ‘green diesel’). ‘Ultra low sulphur diesel’ means fuel meeting the specification within BS EN 590. Where these standards are succeeded, they should be applied when reasonable. Exemptions to these standards may be granted for specialist equipment or for equipment with alternative emission reduction equipment or run on alternative fuels. Such exemptions shall be applied for in writing to the local planning authority in advance of the use of such vehicles, detailing the reasons for the exemption being sought and clearly identifying the subject vehicles. Exemptions that are granted will be in writing and such vehicles must not be used until written exemption has been issued by the local planning authority.

  13. Approval of a Biodiversity Gain Plan will not be required before development commences. Biodiversity Net Gain The effect of paragraph 13 of Schedule 7A to the Town and Country Planning Act 1990 is that planning permission granted for development of land in England is deemed to have been granted subject to the condition ('biodiversity gain condition') that development may not begin unless: (a) a Biodiversity Gain Plan has been submitted to the planning authority, and (b) the planning authority has approved the plan. The planning authority, for the purposes of determining whether to approve a Biodiversity Gain Plan, if one is required in respect of this permission would be the London Borough of Richmond upon Thames. There are statutory exemptions and transitional arrangements which mean that the biodiversity gain condition does not always apply. These are listed below. Based on the information available this permission is considered to be one which will not require the approval of a biodiversity gain plan before development is begun because one or more of the statutory exemptions or transitional arrangements in the list below is/are considered to apply. Statutory exemptions and transitional arrangements in respect of the biodiversity gain condition. 1. The application for planning permission was made before 12 February 2024. 2. The planning permission relates to development to which section 73A of the Town and Country Planning Act 1990 (planning permission for development already carried out) applies. 3. The planning permission was granted on an application made under section 73 of the Town and Country Planning Act 1990 and (i) the original planning permission to which the section 73 planning permission relates* was granted before 12 February 2024; or (ii) the application for the original planning permission* to which the section 73 planning permission relates was made before 12 February 2024. 4. The permission which has been granted is for development which is exempt being: 4.1 Development which is not 'major development' (within the meaning of article 2(1) of the Town and Country Planning (Development Management Procedure) (England) Order 2015) where: (i) the application for planning permission was made before 2 April 2024; (ii) planning permission is granted which has effect before 2 April 2024; or (iii) planning permission is granted on an application made under section 73 of the Town and Country Planning Act 1990 where the original permission to which the section 73 permission relates* was exempt by virtue of (i) or (ii). 4.2 Development below the de minimis threshold, meaning development which: (i) does not impact an onsite priority habitat (a habitat specified in a list published under section 41 of the Natural Environment and Rural Communities Act 2006); and (ii) impacts less than 25 square metres of onsite habitat that has biodiversity value greater than zero and less than 5 metres in length of onsite linear habitat (as defined in the statutory metric). 4.3 Development which is subject of a householder application within the meaning of article 2(1) of the Town and Country Planning (Development Management Procedure) (England) Order 2015. A 'householder application' means an application for planning permission for development for an existing dwellinghouse, or development within the curtilage of such a dwellinghouse for any purpose incidental to the enjoyment of the dwellinghouse which is not an application for change of use or an application to change the number of dwellings in a building. 4.4 Development of a biodiversity gain site, meaning development which is undertaken solely or mainly for the purpose of fulfilling, in whole or in part, the Biodiversity Gain Planning condition which applies in relation to another development, (no account is to be taken of any facility for the public to access or to use the site for educational or recreational purposes, if that access or use is permitted without the payment of a fee). 4.5 Self and Custom Build Development, meaning development which: (i) consists of no more than 9 dwellings; (ii) is carried out on a site which has an area no larger than 0.5 hectares; and (iii) consists exclusively of dwellings which are self-build or custom housebuilding (as defined in section 1(A1) of the Self-build and Custom Housebuilding Act 2015). 4.6 Development forming part of, or ancillary to, the high speed railway transport network (High Speed 2) comprising connections between all or any of the places or parts of the transport network specified in section 1(2) of the High Speed Rail (Preparation) Act 2013. * 'original planning permission means the permission to which the section 73 planning permission relates' means a planning permission which is the first in a sequence of two or more planning permissions, where the second and any subsequent planning permissions are section 73 planning permissions. Irreplaceable habitat If the onsite habitat includes irreplaceable habitat (within the meaning of the Biodiversity Gain Requirements (Irreplaceable Habitat) Regulations 2024) there are additional requirements for the content and approval of Biodiversity Gain Plans. The Biodiversity Gain Plan must include, in addition to information about steps taken or to be taken to minimise any adverse effect of the development on the habitat, information on arrangements for compensation for any impact the development has on the biodiversity of the irreplaceable habitat. The planning authority can only approve a Biodiversity Gain Plan if satisfied that the adverse effect of the development on the biodiversity of the irreplaceable habitat is minimised and appropriate arrangements have been made for the purpose of compensating for any impact which do not include the use of biodiversity credits. The effect of section 73D of the Town and Country Planning Act 1990 If planning permission is granted on an application made under section 73 of the Town and Country Planning Act 1990 (application to develop land without compliance with conditions previously attached) and a Biodiversity Gain Plan was approved in relation to the previous planning permission ('the earlier Biodiversity Gain Plan') there are circumstances when the earlier Biodiversity Gain Plan is regarded as approved for the purpose of discharging the biodiversity gain condition subject to which the section 73 planning permission is granted. Those circumstances are that the conditions subject to which the section 73 permission is granted: (i) do not affect the post-development value of the onsite habitat as specified in the earlier Biodiversity Gain Plan, and (ii) in the case of planning permission for a development where all or any part of the onsite habitat is irreplaceable habitat the conditions do not change the effect of the development on the biodiversity of that onsite habitat (including any arrangements made to compensate for any such effect) as specified in the earlier Biodiversity Gain Plan.
  14. The approved works shall be carried out in accordance with the details approved by this application. Any further works beyond this may be subject to enforcement action under Sections 7-9 of the Town and Country Planning (Listed Buildings and Conservation) Act 1990.
  15. If significant archaeological remains are unexpectedly encountered, excavation works should temporarily cease and the applicant should inform GLAAS of the findings and seek advice.
