Dust Management Plans

Dustmanagement UK can assist in drawing up a Dust Management Plan for your construction site. A plan should include many things, the basiscs of which are covered below, contact us for more information and help wiht your plan.

Method Statement

A Method Statement should be submitted prior to any works being carried out.  As well as the risk assessment, a method statement will include the proposed dust control measures and a timetable of dust generating activities.  A method statement should cover all phases of the development and take into account all contractors or sub-contractors.

The content of a Method Statement will be determined by a risk assessment, but typical features to include are outlined below.

All sites:

  • Summary of work to be carried out.
  • Description of site layout and access – including proposed haul routes, location of site equipment including supply of water for damping down, source of water (wherever possible from recycled or grey water), drainage and enclosed areas.
  • Inventory and timetable of all dust generating activities.
  • List of all dust and emission control methods to be used.
  • Timescale of dust producing activities.
  • Details of any fuel stored on site.
  • Identification of an authorised on-site responsible person. Ideally this person needs to have knowledge of pollution control and vehicle emissions.
  • Summary of monitoring protocols and agreed procedure of notification to the enforcing authority nominated person(s).
  • Details and procedure on using a site log book (to record information including exceptional incidents causing dust episodes and action taken, identification and details of vehicle washing, site inspections).

Dust Control Measures

Developers will need to ensure that all on-site contractors follow best practicable means (BPM) at all time to minimise dust and emissions.  The following identifies the activities that are most likely to produce dust and outlines BPM.  These measures have been intended to be stringent but achievable to deal with the specific air pollution problems facing Contractors.

Pre-site preparation

For all sites with areas of open ground that are close to receptors, contractors should follow best practice to prevent dust from being generated outside the boundary.  The method statement is designed to ensure that machinery and dust generating activities are not located close (or in the direction of prevailing wind) to boundaries and sensitive receptors.  For high risk sites, developers may need to carry out some monitoring before work begins to identify baseline dust levels.  This information can be used to inform site design and layout.

Site Planning

•Carry out main dust causing activity in rainy season.

•Plan site layout–locate dust activity away from sensitive receptors.

•Plan site layout – minimise movement of construction traffic around site.

•Erect solid barriers to site boundary

•No bonfires

•All site personnel to be fully trained

•Trained and responsible manager on site during working times to maintain logbook and site inspections.

•Put in place dust real-time monitors across site.

Haul Routes / Construction Traffic

Surface of Haul Routes/Roads:

Un-paved haul routes can account for a significant proportion of fugitive dust emissions, especially in dry or windy conditions, when the generation of dust through the movement of vehicles is exacerbated.  It is recommended that to ensure good practice, contractors should ensure that hard surfaces or paving is used for all haul routes, it is recognised however that this will not necessarily be practicable and therefore, the use of a suitable additive binder/dust suppressant is recommended even if routes are temporary.

Haul Routes General

•All vehicles to switch off engines – no idling vehicles.

•Fixed wheel washing on leaving site.

•Damping down of haul routes with water plus a suitable additive binder/suppressant.

•10 Km/h limit around site (higher limits may be appropriate dependant on the site).

•Hard landscaping of haul routes or use of a suitable dust suppressant.

•On-road vehicles to comply to set emission standards (eg Euro IV) Non Road Mobile Machinery (NRMM) should be fuelled by ULSD and fitted with exhaust after-treatment where available.

•All loads leaving site to be covered.

•No site runoff of water / mud.

Demolition Works

•Use water as dust suppressant plus a suitable wetting agent.

•Use enclosed chutes and covered skips.

•Wrap building to be demolished.

•Cutting equipment to use water as suppressant or suitable LEV (local exhaust ventilation).

•Ensure crusher/screener is adequately suppressed for dust and that water bowsers are fully operational.

Earth Moving Works

•Not on dry or windy days

•Use water as dust suppressant plus suitable wetting agent where applicable.

•Re-vegetate earthworks and exposed areas

Site Activities

•Minimise dust generating activities on windy and dry days.

•Use water as dust suppressant plus a suitable additive binder/suppressant where applicable.

•Cover, seed and fence stockpiles to prevent wind-whipping.

Implementation of the suggested mitigation measures above will help reduce the impact of the construction activities to medium; or even low risk.
