Jetty Non Technical Summary - EDF Hinkley Point

Mitigation
6.3.8 In this EIA, those impacts assessed as being of potentially greater than minor adverse
significance (i.e. impacts of moderate and major adverse significance) are the focus of
mitigation, although every attempt has been taken to avoid, reduce and mitigate impacts
through design change and adoption of best practice.
6.3.9 The preferred hierarchy of mitigation is prevention first, then minimisation and, only as a
last resort, compensation or remediation. The definitions of these are as follows:
• prevention: avoid, relocate, modify the design and / or do not carry out the
development;
• reduction: introduce screens / blinds, modify design, alter technology, reduce size
and scale of development etc; and
• compensation or remediation: compensation to provide like-for-like replacement for
any lost environmental elements (e.g. open green spaces, public facilities, wildlife
area etc).
6.3.10 Where possible, mitigation has been built into the jetty development (e.g. through the
options chosen and through its design) and may be accepted, offset by other benefits of
the jetty development or managed by the imposition of conditions within the HEO and/or
on any licences granted.
Residual Impacts
6.3.11 The final step in the EIA process is the assessment of the residual impacts (i.e. those
impacts remaining after the implementation (where necessary) of the proposed mitigation
measures). Residual impacts are rated in accordance with the definitions of significance
provided above. In this EIA, residual impacts assessed as minor or negligible are
considered to be insignificant. More significant impacts may be accepted, offset by other
benefits of the jetty development, or managed by the imposition of conditions within the
HEO and / or on any licences granted.
Cumulative Effects Assessment
6.3.12 Cumulative effects are the additive and interactive effects that can arise from the jetty
development cumulatively with other plans and projects. The EIA considers the jetty
development cumulatively with the site preparation works, the Hinkley Point C Project,
and other plans and projects which overlap in time and space (as regards those
receptors that potentially could be affected).
6.4 Consideration of Alternatives
6.4.1 In accordance with the EIA Directive, an ES should outline the main alternatives
considered by the applicant and present the main reasons for selecting the application
site and design.
No Development Alternative
6.4.2 Proposed as Preliminary Works, the jetty development would allow EDF Energy to meet
the target date of 2018 for the start of nuclear power generation by enabling the
construction of Hinkley Point C to begin as early as possible after grant of the DCO. The
2018 target is clearly set out in the draft National Policy Statements related to energy and
Hinkley Point C Preliminary Works
