From 1 September 2015 non road mobile machinery (NRMM) of net power between 37kW and 560kW used in London will be required to meet the standards set out in the EU Directive 97/68/EC and its subsequent amendments.
Engines with a variable or constant speed will be effected where they are used on the site of any major development within Greater London will need to meet Stage IIIA of the directive as a minimum and for any site within the Central Activity Zone or Canary Wharf they will be required to meet stage IIIB with progression to tighter engine emission rules in 2020.
All eligible NRMM should meet the standards unless it can be demonstrated that the machinery is not available or that a comprehensive retrofit to meet emission standards is not feasible. In this situation every effort should be made to use the least polluting equipment available including retrofitting technologies to reduce particulate matter emissions.
These NRMM emissions standards will apply to all construction projects which are active from September 2015 including those which commenced before this date.
An inventory of all NRMM should be kept on-site stating the emission limits for all equipment.
Under the new rules, all construction sites in the centre of London and sites building more than ten homes or larger than 1,000 square feet in Greater London will have to replace or retrofit 10-year-old plant unless an exemption can be granted.
To help with implementation of the scheme a new online register has been set up here making it easy for site managers to register all construction machinery within the London catchment area.
