• Citation: S.I. 1997/2471
• Sections: 9

Section 1 Citation, commencement and interpretation

(1) These Regulations may be cited as the Surface Waters (Fishlife) (Classification) (Scotland) Regulations 1997 and shall come into force on 18th November 1997.

(2) Expressions used in these Regulations which are also used in Directive 78/659/ EEC (the quality of fresh waters needing protection or improvement in order to support fish life) shall have the same meaning as in that Directive.

Section 2 Classification of waters

The classifications SW (“salmonid waters”) and CW (“cyprinid waters”), and the criteria for those classifications set out in the Schedule to these Regulations, shall apply for classifying controlled waters which are fresh waters which need protection or improvement in order to support fishlife.

Section 3 Compliance with relevant requirements

(1) Subject to paragraphs (2) and (3) below, any waters classified under these Regulations shall be treated in relation to any period of twelve months as complying with the requirements specified in the Schedule to these Regulations for waters of the relevant class for any parameter if in that period in relation to those waters–

(a) in the case of the parameter for pH, non-ionized ammonia, total ammonium, total residual chlorine or total zinc, 95 per cent of the samples taken for that parameter in accordance with regulation 4 below comply with the requirements;

(b) in the case of the parameter for temperature or dissolved oxygen, the percentage specified in that Schedule of samples taken for that parameter in accordance with regulation 4 below comply with the requirements.

(2) When the frequency of sampling is lower than one sample per month for any parameter mentioned in paragraph (1)(a) above in relation any waters classified under these Regulations, 100 per cent of samples taken for that parameter in accordance with regulation 4 in relation to those waters must comply with the requirements specified in the Schedule to these Regulations for waters of the relevant class.

(3) Non-compliant samples shall be ignored for the purposes of paragraphs (1) and (2) above if they are the result of a flood or any other natural disaster.

Section 4 Sampling and analysis

(1) The Scottish Environment Protection Agency shall ensure that waters classified under these Regulations are sampled and samples are analysed in accordance with the following provisions of this regulation.

(2) Samples in relation to any waters classified under these Regulations shall always be taken at the same sampling point.

(3) The Scottish Environment Protection Agency shall fix the exact position of the sampling point, and the depth at which samples are to be taken, having regard in particular to–

(a) the distance of the sampling point to the nearest point where pollutants are discharged; and

(b) local environmental conditions.

(4) Subject to paragraphs (5) and (6) below, sampling for any parameter shall be carried out at least at the minimum frequency specified in the Schedule to these Regulations for that parameter for waters of the relevant class.

(5) Where the Scottish Environment Protection Agency’s records show that the quality of any waters classified under these Regulations is appreciably higher for any parameter than the minimum required by these Regulations for waters of that class, the Agency may reduce the sampling frequency for that parameter or, if there is no pollution and no risk of deterioration of its quality, it may dispense with sampling for that parameter altogether.

(6) Where sampling shows that the requirements of regulation 3 above are not being complied with, the Scottish Environment Protection Agency shall establish whether this is the result of chance, a natural phenomenon or pollution and shall adopt appropriate measures.

(7) Samples for any parameter shall be analysed using the reference methods of analysis specified in the Schedule to these Regulations in relation to that parameter or methods which are at least as reliable as the reference methods.

Section 5 Derogations

(1) The Scottish Environment Protection Agency may derogate from the requirements of these Regulations–

(a) in the case of requirements marked (0) in the Schedule to these Regulations, because of exceptional weather or special geographical conditions; or

(b) where waters classified under these Regulations undergo natural enrichment in certain substances as a result of which they do not comply with the requirements specified in the Schedule to these Regulations for waters of the relevant class.

(2) In this regulation, “natural enrichment” means a process whereby without human intervention a given body of water receives from the soil certain substances contained therein.

Section 6 Modification of section 30C of the Control of Pollution Act 1974

Section 30C of the Control of Pollution Act 1974 (water quality objectives) shall have effect–

(a) as if it imposed a duty on the Secretary of State to exercise the powers conferred on him by that section to classify under these Regulations such waters as are appropriate for the purposes of giving effect to Directive 78/659/EEC in Scotland; and

(b) in relation to the performance of that duty, as if subsections (4) and (5) of that section were omitted.

Section 7 Information required in connection with implementation of the Directive

(1) The Scottish Environment Protection Agency may serve on any person a notice requiring that person to furnish the Agency within a period or at times specified in the notice, and in a form and manner so specified, with such information as is reasonably required by the Agency for the purposes of giving effect to Directive 78/659/EEC .

(2) A person who fails without reasonable excuse to comply with the requirements of a notice served on him under this regulation shall be guilty of an offence and liable–

(a) on summary conviction, to a fine not exceeding the statutory maximum;

(b) on conviction on indictment, to a fine or to imprisonment for a term not exceeding two years, or both.

Section 1

Temperature measured downstream of a point of thermal discharge (at the edge of a mixing zone) must not exceed the unaffected temperature by more than 1.5°C for salmonid waters and 3°C for cyrpinid waters.

Derogations limited in geographical scope may be decided by the Scottish Environment Protection Agency if the Agency can show that there are no harmful consequences for the balanced development of the fish population.

Section 2

Thermal discharges must not cause the temperature downstream of the point of thermal discharge (at the edge of the mixing zone) to exceed–

(a) 10°C (0) during the breeding season in the case of

(b) at other times or in the case of waters which do not contain such species,
