# The East Anglia ONE Offshore Wind Farm Order 2014, Paragraph 11: Ground subsidence monitoring scheme in respect of statutory undertakers’s apparatus

Extent: E+W+S

(1) No works within 15 metres of any apparatus or alternative apparatus shall commence until a scheme for monitoring ground subsidence (“referred to in this paragraph as the monitoring scheme”) which is capable of interfering with or risking damage to statutory undertakers’s apparatus has been submitted to and approved by the relevant statutory undertakers, such approval not to be unreasonably withheld or delayed.
(2) The ground subsidence monitoring scheme described in sub-paragraph (1) shall set out—
(a) the apparatus which is to be subject to such monitoring;
(b) the extent of land to be monitored;
(c) the manner in which ground levels are to be monitored;
(d) the timescales of any monitoring activities; and
(e) the extent of ground subsidence which, if exceeded, shall require the undertakers to submit for statutory undertakers’s approval a ground subsidence mitigation scheme in respect of such subsidence in accordance with sub-paragraph (3).
(3) The monitoring scheme required by sub-paragraphs (1) and (2) must be submitted within 56 days prior to the commencement of any works authorised by this Order or comprised within the authorised development. Any requirements of the statutory undertakers will be notified within 28 days of receipt of the monitoring scheme. Thereafter the monitoring scheme must be implemented as approved, unless otherwise agreed in writing with the statutory undertakers.
(4) As soon as reasonably practicable after any ground subsidence identified by the monitoring activities set out in the monitoring scheme has exceeded the level described in sub-paragraph (2)(e), a scheme setting out necessary mitigation measures (if any) for such ground subsidence (referred to in this paragraph as a “mitigation scheme”) shall be submitted to the statutory undertakers for approval, such approval not to be unreasonably withheld or delayed; and any mitigation scheme must be implemented as approved, unless otherwise agreed in writing with the statutory undertakers except that the statutory undertakers retains the right to carry out any further necessary protective works for the safeguarding of their apparatus and can recover any such costs in line with paragraph 10.
