Regulation 8 Waivers
Subject to the following provisions of this regulation, the Secretary of State may waive any requirement to endeavour to respect the relevant limit value specified in Schedule 2 for any parameter in relation to any waters if he considers it appropriate to do so–
as a result of any flood or other natural disaster;
where the waters undergo natural enrichment in certain substances as a result of which the waters would exceed the standard for that parameter;
in the case of a shallow loch or virtually stagnant surface water, for parameters marked with an asterisk in Schedule 2.
The Secretary of State shall not waive any standard if that would result in a danger to public health.
Paragraph (1)(c) above shall only apply in relation to a loch if–
the depth of the water does not exceed 20 meters;
the exchange of water is slower than a year; and
waste water is not discharged into 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.
