This environmental impact assessment for Kriegers flak ... - Vattenfall

ASSESSMENT CRITERIA CONT´D
• The structure causes major impact on a nature
protection object of local value (reasonable
impact – minor value)
Minor/no impact (minor value – minor impact)
• The structure interferes with a local nature
protection object or causes impact on an object
of higher value. The values can quickly be
restored following the operational phase of the
structure.
• The structure causes no risk for measurable
impact on the biological diversity of an object
of national interest.
Conclusion
No marine mammals reside permanently in the area,
there are no layover places in the vicinity and grey
seal, harbour seal and porpoises are only sporadically
assumed to cross the area. The area is therefore considered
to be of less importance for marine mammals.
Limited negative impact will occur during the construction
and dismantling phases by emitting, what the
mammals consider, an unpleasant signal. This is done
to stop mammals from residing at the site during the
construction and dismantling phases. No mammals are
expected to be hurt or damaged during the operation
of the structure.
This, together with the fact that only few individuals
sporadically are in the area, results in small negative
impact on marine mammals.
12.5 Cultural environment
12.5.1 Impact
In connection with the dredging work at Kriegers Flak,
there is a risk that ancient remains/wrecks could be
destroyed.
The studies that have been made show that no ancient
remains or wrecks have been found in the area of the
planned wind farm. The only wreck that has been found lies
at a safe distance about 1 850 metres north of the area.
12.5.2 Mitigating measures
Careful investigations have been made in order to establish
whether ancient remains or wrecks are present
in the area (see Chapter 11.7).
If a wreck/ancient remains still would be found dur-
CONSEQUENSES OF THE WIND FARM 137
ing the construction phase, Sweden Offshore commits
not to touch or dig in the ancient remains/wreck, to
stop all work if an ancient remain/wreck is found and
report the Þ nd to the county council.
12.5.3 Assessment
ASSESSMENT CRITERIA
Very high impact (high value – high
impact)
• The structure extinguishes some of the values
that identifi es and motivates the area as of national
or international interest for the cultural
environment (for example a world heritage
site).
Big impact (high value – reasonable
impact/reasonable value – high impact)
• The structure causes big impact on some of
the values that identifi es and motivates the
area as of national or international interest for
the cultural environment (for example a world
heritage site).
• The structure extinguishes some of the values
that identifi es and motivates the area as of national
or international interest for the cultural
environment (for example a world heritage
site).
• The structure extinguishes a cultural environment
value of regional interest with high
values.
Reasonable impact (reasonable value
– reasonable impact)
• The structure has an impact on a cultural
environment object of national or international
interest.
• The wind turbine causes impact on a regional
cultural environment object, where only part
of the object is extinguished.
• The structure extinguishes a cultural environment
object of local value.
