Measurement of treated fluid
2.—(1) In order to ensure that the treated fluid complies with the levels in paragraph 1(1)(b) an operator who treats fluid in accordance with that paragraph must as a minimum carry out the following measurements.
(2) The operator must continuously monitor the level of suspended solids in the treated fluid or alternatively measure it three times a day.
(3) Once a week the operator must measure the level of suspended solids in the treated fluid by a method that conforms with “Suspended Settleable and Total Dissolved Solids in Waters and Effluents(1)”.
(4) Once a week the operator must measure the biochemical oxygen demand of the treated fluid by a method which conforms with the “5 day Biochemical Oxygen Demand (BOD5)(2)”.
(5) If any of these measurements demonstrates that the treated fluid does not comply with the levels in paragraph 1(1)(b) the operator must ensure that the operator only discharges the treated fluid in accordance with paragraph 1(1)(a) until further tests show that the treatment system is achieving the required levels.
(6) It is an offence to fail to comply with any provision of this paragraph.
