Monitoring Requirements 6.1 Dust Monitoring

The overall approach to dust control for the main works is based on visual monitoring combined with targeted ambient dust monitoring; good management of the construction areas; and a rapid response to any of the triggers outlined in Sections 6.3.2 or 6.3.4, or complaints received. Good practice focusing on proactive measures will aid in avoiding significant dust emissions, however if dust emissions do occur, the monitoring will help to identify such occurrences and enable a prompt response.

6.2 Visual Inspection and Monitoring Methods Visual monitoring of all construction areas will be undertaken by the Environment and Sustainability Manager (or delegated person) on a daily basis, or more frequently if conditions change. This type of monitoring relates to the control measures described in Section 5 of this AQ DWP and will include proactive measures to avoid dust emissions. Table 6-1 below describes the visual dust monitoring activities to be undertaken during construction. Outcomes of visual inspections are to be recorded in the Air Quality Log (log sheet template provided in Appendix D). Table 6-1: Visual Dust Monitoring Programme

Monitoring activity

Frequency

Check weather forecasts for strong winds (winds that may exceed the trigger levels described in section 6.3.4) and absence of rainfall to plan appropriate work schedule and dust management response.

Daily

Inspect land adjacent to the site, construction exits and adjoining roads for the presence of dust deposition and/or accumulation of dust material.

Twice daily

Observe weather conditions including wind and rain via observations and data outputs from weather stations.

Daily and as conditions change

Inspect all exposed un-stabilised surfaces for dampness and that the extent of those areas is being minimised.

Daily and as conditions change

Inspect stockpiles for dampness and height of no more than 3°m (or enclosure, covering or stabilisation where required).

Daily and as new activities commenced

Inspect dust generating activities for effectiveness of dust management measures and avoidance of visible dust emissions beyond the boundary of the site.

Daily and as new activities are commenced

Inspect watering systems (sprays and water carts) to ensure equipment is maintained and functioning to effectively dampen exposed areas.

Weekly

Monitor dust generating activities and water application rate (for effective dampening).

In winds over 5 m/s (1-hour average)

Inspect wheels of all trucks exiting the Site to public roads for evidence of tracked material (to be washed and removed as required)

All truck departures

Check for dust on local roads being used to access the site.
