# The Tees Combined Cycle Power Plant Order 2019, Paragraph 19: Control of noise during operation


(1) The commissioning of any phase of the authorised development must not commence until a written programme for the monitoring and control of noise during the operational phase has been submitted to and approved by the relevant planning authority in consultation with the Environment Agency.
(2) The programme submitted and approved must specify—
(a) each location from which noise is to be measured;
(b) the method of noise measurement, which must be in accordance with British Standard 4142:2014;
(c) the maximum permitted levels of noise at each monitoring location (such levels not to exceed 3 decibels above a baseline to be agreed in writing with the relevant planning authority);
(d) provision requiring the undertaker to take noise measurements as soon as possible following a request by the relevant planning authority and to submit the measurements to the relevant planning authority as soon as they are available;
(e) details relating to
(i) the rebuilding of the western boundary sound wall;
(ii) any works that may be required to any parts of the southern boundary sound wall; and
(iii) the subsequent maintenance of the western boundary sound wall and the southern boundary sound wall thereafter; and
(f) the measures to be implemented in the event that any audible acoustic tonal noise is detected from any of the locations referred to in sub-paragraph (2)(a), to ensure such audible acoustic tonal noise is negated.
(3) The level of noise at each monitoring location must not exceed the maximum permitted level specified for that location in the programme, except;
(a) in the case of an emergency,
(b) with the prior approval of the relevant planning authority, or
(c) as a result of steam purging or the operation of emergency pressure relief valves or similar equipment of which the undertaker has given notice in accordance with sub-paragraph (4).
(4) Except in the case of an emergency, the undertaker must give the relevant planning authority 24 hours’ notice of any proposed steam purging or operation of emergency pressure relief valves or similar equipment.
(5) Where the level of noise at a monitoring location exceeds the maximum permitted level specified for that location in the programme because of an emergency—
(a) The undertaker must, as soon as possible and in any event within two business days of the beginning of the emergency, submit to the relevant planning authority a statement detailing—
(i) the nature of the emergency, and
(ii) why it was necessary for the level of noise to have exceeded the maximum permitted level.
(b) If the undertaker expects the emergency to last for more than 24 hours, it must inform local residents and businesses affected by the level of noise at that location—
(i) the reasons for the emergency, and
(ii) how long it expects the emergency to last.
(6) The authorised development must not be commissioned until the western boundary sound wall is fully rebuilt and any necessary works to the southern boundary sound wall have been carried out in accordance with the details approved pursuant to sub-paragraph (2)(e) above.
