Part  A  -  Framework  conditions

Observers  in  radar  surveys  must  have  received  instructions  in  radar  technology  and  optimal
operation  of  radar  equipment  from  an  experienced  radar  observer  (Hüppop  et  al.  2002).
The  interpretation  of  bat  call  recordings  and  the  identification  of  species  are  to  be  carried  out
by  persons  with  long-standing  experience  in  the  bio-acoustic  analysis  of  bat  calls.
Proof  of  adequate  qualification  in  the  field  of  noise  and  vibration  has  to  be  provided  (e.  g.  accreditation ­
  according  to  DIN  EN  45001  for  noise  and  other  measurements  of  wind  turbine
emissions).
For  the  purpose  of  quality  assurance,  the  submission  of  expert  reports  (Section  13)  to  the
planning  approval/approval  authority  must  be  supplemented  by  documentation  of  data  collection ­
  and  evaluation  that  is  both  reasonable  and  focused  on  features  of  conservation  interest. ­


7  Decommissioning  phase
The  wind  turbines  including  their  foundations  have  to  be  removed  completely,  with  subsequent ­
  onshore  disposal.
In  principle,  the  monitoring  requirements  during  this  phase  correspond  to  those  in  the  construction ­
  phase  as  specified  in  the  StUK.  Possible  environmental  impacts  depend  mainly  on
the  dismantling  techniques  used,  which  are  expected  to  undergo  major  technical  improvement ­
  during  the  coming  decades  when  numerous  oil  and  gas  platforms  are  due  for  decommissioning. ­
  Therefore,  the  final  scope  of  standardised  monitoring  will  be  determined  at  a  later
date.  Should  the  need  arise  in  the  meantime,  the  planning  approval/approval  authority  shall
establish  a  study  framework  for  corresponding  monitoring  measures  in  the  specific  case.

8  Further  studies  and  analyses
In  addition  to  the  studies  described  in  the  StUK  at  hand,  further  requirements  may  result  from
other  regulations  as  well  as  from  the  incidental  provisions  of  the  respective  planning  approval
decision/the  respective  permit.  In  particular,  the  standard  at  hand  is  closely  linked  to  the  other
standards  published  by  the  BSFI  (Standard  “Design  of  Offshore  Wind  Turbines”  (BSFI  2007),
Standard  “Ground  Investigations  for  Offshore  Wind  Farms”  (BSFI  2008));  explicit  reference  is
made  here  to  their  content  (surveys  in  the  context  of  collision  and  risk  analysis,  environmental
impact  studies  in  co-ordination  with  the  design  basis  and  preliminary  draft,  due  consideration
of  the  planned  noise  reduction  measure  when  drawing  up  the  basic  design,  etc.).
