Paragraph 9 Design parametersI1
England and Wales As made
(1)
The authorised scheme must be constructed in accordance with the parameters assessed in the environmental statement and set out in Table 4 below.
(2)
The parameters in Table 4 do not allow works in relation to wind turbine generators that give rise to any materially new or materially different environmental effects to those identified in the environmental statement based upon the two assessed scenarios set out in Table 3.5 of the environmental statement.
