BOC Immingham Dissolved Acetylene Project Environmental Statement: Vol. 2 Main Text
Mitigation Measures
Construction
6.98 With appropriate good working practices and the production and implementation of the CEMP, it is
expected that there will be no significant air quality impacts during the construction phase of the
development. Therefore no specific mitigation measures are deemed necessary.
Operation
6.99 Operational process emissions will be controlled as a result of the Project design (e.g. through the
requirements of BAT and occupational health considerations), the implementation of good practice
and regulation, monitoring and control measures (e.g. through the EP and the EMS).
6.100 Atmospheric emissions resulting from the operation of the Dissolved Acetylene Project are
expected to have a negligible impact on human and ecological receptors and specific additional
mitigation measures are not proposed.
6.101 Air quality impacts from road traffic generated by the development have been assessed to be
negligible and no specific mitigation measures are proposed.
Residual Impact Assessment
6.102 Since no mitigation measures are proposed in relation to impacts associated with air quality, the
significance of impacts does not change from that described above.
Recommendations
6.103 The CEMP should include a method statement detailing dust suppression techniques to be
employed during the course of construction. In accordance with their planning advice 24 , it is
recommended that this is submitted and agreed with NELC prior to commencement of
development.
Summary
6.104 Construction dust emissions are considered not likely to affect sensitive receptors, which are over
500 m from the facility. Potential dust raising activities will be controlled through the use of good
practice measures, to be specified in a CEMP. This short-term impact is considered to be
negligible.
6.105 Additional traffic generated by the development during its construction and operational phases will
not cause any significant impact on local air quality as the changes do not exceed the DMRB
criteria that trigger the need for a quantitative assessment. There are no sensitive receptors within
200 m of roads that are likely to be affected by the development. The effect of traffic emissions is
considered to be negligible.
6.106 Under the EA permitting regime, BAT must be applied to control emissions (for design, operation
and management of the facilities). Process emissions from the facility were assessed for their
effects on air quality using the EA’s H1 screening method. In all cases the emissions were found
to be insignificant (i.e. less than 10% of short term and less than 1% of the long term health and
ecological based assessment criteria). Given the distance to the nearest sensitive receptors, the
effect of process emissions will be negligible.
6.107 Consideration was also given to whether the facilities would result in odour issues; the
assessment concluded that the Dissolved Acetylene Project was unlikely to give rise to odour
complaints.
