Comment
The potential environmental impacts of the decommissioning phase on marine mammals (and on fish) and how such impacts may be mitigated should be considered. For example, the use of any explosives to remove structures from the sea bed.
JNCC
East Anglia ONE (ERM 2012)
Consider the damage or potential mortality of fish at early life stages when piling. Any impacts at this stage could affect successive generations and as such could impact upon the population in this area.
Response / where addressed in the PEI
EATL have committed not to use explosives to remove structures from the sea bed.
Section 11.6.
Potential effects of piling noise on fish at early life stages are assessed.
Consultation undertaken with IMARES to improve the knowledge of the effect of piling noise on fish larvae (2012).
Request methodology for targeted fish surveys agreed with Cefas and JNCC.
Recommended reference made to the indirect effects on prey. Impacts of spawning fish are a key concern.
Identification of fish spawning and nursery grounds in reports 1998 and 2010 differ in location and size of spawning grounds. Evidence which will be used to inform the ES should be comprehensive and up-to-date, and where there are uncertainties, the worst case scenario should be assessed.
Appendix 11.1
Potential effects on key prey species and on spawning fish are assessed (section 11.6).
Section 11.4.2 and Appendix 11.2. Currently available up-to-date data in relation to the distribution of fish spawning grounds and nursery grounds are provided. This includes the distribution of nursery and spawning grounds as defined in Ellis et al. (2010) and Coull et al. (1998) and an indication of the recent temporal and spatial distribution of spawning, based on the results of monthly ichthyoplankton surveys carried out from April 2010 to March 2011 in the southern North Sea by IMARES (van Damme et al. 2011).
