-
Had the surveys been completed according to the prescriptions in the EMP
and/or had they achieved their objectives?;
-
Did the surveys involve a robust survey design and relevant, achievable objec-
tives?; and
-
Were the management actions demonstrably effective or, if there were no data
to assess this, logical?;
3. Collate all data, information and evidence on all relevant actions conducted.
4. Develop a mechanism to allow collaborative decision making and a simple
method of documenting decisions made.
The process was accepted by the EPA, and a working group formed. This group
worked through each of the tasks in a series of workshops. All decisions agreed to
by the working group were documented.
We employed the standard qualitative risk likelihood criteria shown in Table
1
and the risk consequence criteria shown in Table
2
.
The assessments were documented in the framework shown in Table
3
.
A summary of all the monitoring and management actions conducted at the
BPWF and SBWF over the last 10 years are provided in
Appendix

Description, in terms of the life of a wind farm
project
Indicative frequency (not a
statistical expectation)
Descriptor
Probable
Recurs throughout the life of the wind farm
(annually or every few years)
Once a year (or more
frequently)
Likely
Expected within life of the farm
Once in 20 years
Possible
Expect to occur in lifetime of one in fi ve wind
farms
Once in 100 years
Rare
May have occurred or could occur during
lifetime of one wind farm in Australia
Once in 1,000 years
Incredible
Not expected in the life of any wind farm in
Australia
Once in 10,000 years

Consequence examples. Consequence is the consequence of a
single event
Extreme
Very marginal population of a threatened species
Potential for major disruption to species
Critical Threatened species
Potential for disruption to regional or local population
Major
Non-marginal species, not threatened
Impact limited to local group
Minor Short term, localised disruptions
