10.—(1) In this regulation—
(a)a “relevant condition” means a condition imposed for the purposes of regulation 6(2) in a consent under Chapter II of Part III of the Water Resources Act 1991;
(b)“the operator” means, in relation to a relevant condition, the person who operates the urban waste water treatment plant, discharges from which are authorised by the consent in which that condition is imposed.
(2) Where the operator is required by a relevant condition to provide any apparatus for the purpose of measuring or recording the volume, rate of flow, nature, composition or temperature of any waste water, or for the purpose of collecting samples of waste water, any such apparatus so provided shall be presumed to register accurately unless the contrary is shown.
(3) Any record—
(a)produced by any such apparatus as is mentioned in paragraph (2) above; or
(b)made by or on behalf of the operator in order to comply with a relevant condition,
shall be evidence of the matters appearing from the record and shall, in any proceedings under Chapter II of Part III of the Water Resources Act 1991, be admissible in evidence against the operator.
(4) Where—
(a)an entry is required by a relevant condition to be made in any record as to the observance of that or any other relevant condition; and
(b)the entry has not been made,
that fact shall be admissible as evidence that that condition or, as the case may be, that other condition has not been observed.
(5) Where, in compliance with a relevant condition, a sample of waste water is collected by apparatus installed for the purpose of collecting such samples automatically, the sample shall be treated, for the purpose of section 209 of the Water Resources Act 1991 (evidence of samples and abstractions), as being taken only at the time when it is removed from that apparatus.
(6) For the purposes of the said section 209, a sample of waste water which is taken and analysed by the operator in compliance with a relevant condition shall not be treated as being taken on behalf of the Authority.
