BOC Immingham Dissolved Acetylene Project Environmental Statement: Vol. 2 Main Text
Consultation
8.10 No specific consultation has been undertaken in the preparation of this Chapter. Most of the
responses to the Scoping Report did not relate to water quality. The EA noted that the site is
considered to be of relatively low sensitivity with respect to groundwater issues but the proximity
of surface waters to the site warranted the proposed GI works (see Chapter 7). The EA also noted
that the Scoping Report addressed the potential environmental risk to surface water and pointed
out that the EA is already in discussions with BOC in relation to this issue and the EP.
Other Information Data Sources
8.11 The data sources used to develop the Scoping Report 3 have also been used to develop this ES
chapter.
8.12 Water quality data have been obtained from the EA to improve the understanding of the baseline
condition of the study area. The data relating to the sampling locations described in Table 8.1 and
illustrated on Figure 8.1 were deemed the most appropriate for the water quality assessment for
the Dissolved Acetylene Project. No water quality data are available for the Middle Drain.
8.13 Additional water quality data have been provided by the EA for sampling sites further upstream
and downstream of the Middle Drain discharge point into the Humber Estuary. These datasets
have not been considered in this assessment, as their value is limited due to the dilution capacity
of the Humber. Therefore only data in proximity to the discharge is used to inform the baseline
assessment.
