# The Willington C Gas Pipeline Order 2014, Paragraph 11: Ground subsidence monitoring scheme in respect of statutory undertaker’s apparatus

Extent: E+W+S

(1) No works within 15 metres of any apparatus or alternative apparatus that are capable of interfering with or risking damage to statutory undertakers’ apparatus may commence until a scheme for monitoring ground subsidence (referred to in this paragraph as the “monitoring scheme”) has been submitted to and approved by the relevant statutory undertaker, such approval not to be unreasonably withheld or delayed.
(2) The monitoring scheme must 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, require the undertaker to submit for the statutory undertaker’s approval a ground subsidence mitigation scheme in respect of such subsidence in accordance with sub-paragraph (4).
(3) The monitoring scheme required by sub-paragraph (1) must be submitted within 56 days prior to the commencement of any works referred to in paragraph 7(1) or 8 (1). Any requirements of the statutory undertaker must be notified to the undertaker 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 undertaker.
(4) As soon as reasonably practicable after any ground subsidence identified by the monitoring activities set out in the monitoring scheme has exceeded the extent provided for 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”) must be submitted to the statutory undertaker 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 undertaker save that the statutory undertaker retains the right to carry out any further necessary protective works for the safeguarding of its apparatus and may recover any such costs in accordance with paragraph 9.
(5) If the monitoring scheme or mitigation scheme would conflict with any aspect of any ground subsidence monitoring scheme or ground subsidence mitigation scheme approved by the relevant planning authority pursuant to Part 2 of Schedule 1 (Requirements), the undertaker may submit a revised monitoring scheme or mitigation scheme to the statutory undertaker for its approval, such approval not to be unreasonably withheld or delayed; and the revised monitoring scheme or mitigation scheme must be implemented as approved, unless otherwise agreed in writing with the statutory undertaker.
