SSD Enquiries, Environment Agency

Dear sir


Thank you for your enquiry regarding the above, we can now respond as


We carried out a site visit on 11^th September and undertook a site audit
at the exploration drilling site near Balcombe. This visit included an
audit of the storage and use of drilling mud additives.


As stated in our Hydrogeological Assessment, Oxirane will only be used as
required by the Drilling Engineer on site. Conditions during drilling may
be such that it may not be used. Cuadrilla have confirmed that Oxirane was
not used during drilling and the drilling additive supplier has confirmed
that Oxirane was not supplied to the site.

Cuadrilla did not report a pipe damaged by seismic activity so a site audit based on company self-reporting sounds inadequate.
