The Network Rail (Ordsall Chord) Order 2015

32.—(1) Network Rail must not in the course of constructing any specified work or protective work or otherwise in connection with such works do or permit anything which may result in the deposit of any polluting materials on, in or over the River and must take such steps as MSCC may reasonably require to avoid or make good any breach of its obligations under this paragraph.

(2) Nothing in article 17 (discharge of water) authorises Network Rail to discharge (directly or indirectly) surface drainage water into the River without the written consent of MSCC (such consent not to be unreasonably withheld).

(3) Network Rail must not in the course of constructing any specified work or protective work or otherwise in connection with such works do or permit anything which may result in the deposit of any other materials in the River and must take such steps as MSCC may reasonably require to avoid or make good any breach of its obligations under this paragraph except that with the written consent of MSCC Network Rail may deposit any other materials into the River.

(4) Any consent of MSCC required under this paragraph must not be unreasonably withheld or delayed and may be given subject to such terms and conditions as MSCC may reasonably require including—

(a) in the case of a discharge of water into the River, concerning the reimbursement by Network Rail of expenses incurred by MSCC in disposing of the water so discharged, being expenses which MSCC would not have incurred but for the discharge; and

(b) in the case of a deposit of any other materials, so as to ensure that the use of the River is not obstructed or rendered less safe and the reimbursement by Network Rail of additional expenses incurred by MSCC in dredging the River, being expenses which MSCC would not have incurred but for the deposit of other materials.
