Regulation 7 Waivers
Subject to the following provisions of this regulation the Secretary of State may waive any requirement to comply with the relevant limit value specified in Schedule 1 for any parameter in relation to waters classified under these Regulations if he considers it appropriate to do so–
as a result of any flood or other natural disaster;
in the case of any parameter marked (0) in Schedule 1, as a result of exceptional meteorological or geographical conditions;
where the waters undergo natural enrichment in certain substances as a result of which the waters would exceed the relevant limit value for that parameter;
in the case of a shallow loch or virtually stagnant surface water, for parameters marked with an asterisk in Schedule 1.
The Secretary of State shall not waive any requirement if that would result in a danger to public health.
Paragraph (1)(d) above shall only apply in the case of a shallow loch where–
the depth of the loch does not exceed 20 metres;
the exchange of water is slower than a year; and
waste water is not discharged in to the loch.
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.
