Coating roadstone with bitumen

1. All reasonable steps must be taken to minimise emissions during start-up and shut-down of the process.

2. Bitumen must be stored and handled within the appropriate temperature range to minimise odour.

3. Dust emissions must be minimised by:

   1. containment of dusty processes; and/or
   2. suppressing dust using water.

4. Potentially dusty materials must be:

   1. stored in storage bays; and
   2. not filled above the external wall height.

5. Recycled asphalt containing coal tar must be:

   1. identified and stored separately from other recycled asphalt; and
   2. removed from site as soon as reasonably practicable.

6. Waste oil (including waste oil referred to as ‘recovered oil’) must not be used as a fuel.

7. All deliveries of filler to silo(s) from tankers must only be made using vehicles fitted with onboard pressure relief valves and filtration equipment.

8. Displaced air, resulting from delivery to silos, must either be:

   1. vented to suitable arrestment equipment; or
   2. back vented to the delivery tanker.

9. Silos and bitumen storage containers must have an overfilling alarm.

10. When loading silos, deliveries must automatically stop where overfilling or over-pressurisation is identified.

11. Emissions to air from the authorised activities must only be made from the roadstone coating process stack(s).

12. The roadstone coating process stack height must be:

    1. greater than or equal to 3 metres above the roof ridge height of the building on which it is located; or
    2. greater than or equal to 3 metres above the ground if it is located separate to any building; and
    3. greater than or equal to the height of any part of a building which is located within a distance of 5 times the uncorrected stack height.

13. Emissions of substance(s) to the air from the roadstone coating process stack(s) must not exceed the emission limit value specified in Table 1.

14. Air of substance(s) to the air from the roadstone coating process stack(s) must not exceed the emission limit value specified in Table 1.

15. The emission of any substance, not specified in Table 1, from the authorised activities must not cause environmental harm.

    Table 1. Emission limit values from roadstone coating

    Substance	Emission Limit Value (mg/m2)
    Dust	50

16. Monitoring must be undertaken at the roadstone coating process stack(s) at the sample port, frequency and using the monitoring standard as specified in Table 2.

17. Sample points must be installed, maintained and appropriately identified so that representative samples may be safely obtained.

18. Monitoring must be undertaken during normal operation and under stable conditions.

19. An alarm system must be provided and maintained in order to provide visual and/or audible notification when arrestment equipment fails or malfunctions.

20. The first monitoring of emissions must be undertaken within four months of the start of operations.

    Dust	Sample port determined in accordance with BS EN 15259	Annual	BS EN 13284-1

21. All releases to the air from the authorised activities, other than condensed water vapour, during normal operation must be free from visible emissions.

22. Measures must be taken to prevent, or where that is not practicable, minimise:

    1. dust;
    2. odour; and
    3. heat emissions

    from the authorised activities.

23. Dust from the authorised activities, which has a significant impact on the environment, people or property, must not be emitted beyond the boundary of the Authorised Place.

24. Offensive odours from the authorised activities as perceived by a SEPA officer must not be emitted beyond the boundary of the Authorised Place.

25. All reasonable steps must be taken to prevent the discharge of water from dust suppression activities which may cause harm to the environment.

26. SEPA must be notified via its pollution hotline contact telephone number as soon as reasonably practicable, and in any case within 24 hours of identification of an event, of any of the following:

    1. an event that has caused or could cause adverse impact to the environment or harm to human health;
    2. an event that results, or could result, in an emission to the environment that is not authorised; and
    3. an event that has caused a breach of a condition of this authorisation.

    In this condition, the meaning of ‘event’ is as defined in the Glossary of Terms. 

27. All measures that are reasonably practicable must be taken to stop an event and to minimise its effect on the environment.

28. Within 14 days of an event a report must be submitted to SEPA detailing:

    1. the reason(s) for the event;
    2. the action(s) taken to stop the event and minimise the impacts; and
    3. the action(s) taken to prevent the event from reoccurring.

29. All information recorded, kept or submitted to SEPA in accordance with a condition of this authorisation must be:

    1. true and accurate; and
    2. kept for a minimum of six years; and
    3. provided to SEPA upon request.

30. Records must be kept of the following:

    1. all monitoring results and verification of compliance with the emission limit values specified in Table 1.

31. The results of the monitoring of emissions, as described in condition 18, must be submitted to SEPA within eight weeks of the date the monitoring took place via email to registry@sepa.org.uk
