PART 3REQUIREMENTS

Control of noise during operational phase

29.—(1) The onshore substation comprising Work No. 16 must not be commissioned unless an operational noise management plan (NMP) for the transmission substation has been submitted to and approved by the relevant planning authority.

(2) The NMP submitted pursuant to sub-paragraph (1) must set out the particulars of—

(a)the noise attenuation and mitigation measures to be taken to minimise noise resulting from the onshore substation, including any noise limits (subject to paragraph (3) below); and

(b)a scheme for monitoring attenuation and mitigation measures provided under sub- paragraph (a) which must include—

(i)the circumstances under which noise will be monitored;

(ii)limitations on noise levels at sensitive locations;

(iii)the locations at which noise will be monitored;

(iv)the method of noise measurement which must be in accord with the relevant British Standards or other agreed noise;

(v)measurement methodology appropriate to the circumstances); and

(vi)a complaints procedure.

(3) The NMP submitted pursuant to sub-paragraph (1) must ensure that the rating levels (noise emissions plus any character correction) from operation of the onshore substation comprising Work No. 16 will not exceed the noise levels set out in the design principles in the design and access statement.

(4) The approved NMP must be implemented throughout the operational life of the authorised development.

(5) Work No. 20 must not commence, excluding onshore site preparation works, until a plan has been submitted to the relevant planning authority which provides details of the equipment to be installed at the substation extension comprising Work No. 20 including—

(a)its operational equipment that has the potential to generate noise emissions; and

(b)characterisation of any sound and the expected frequency and duration of any such emissions to demonstrate that such emissions will not have a discernible or measurable effect in the context of the existing noise environment at the National Grid substation at Bolney.
