This paper describes how the Clyde River Purification Board (the regulatory authority) and Bee‐cham Pharmaceuticals (the identified discharger) agreed and adopted a novel means of controlling a pharmaceutical plant effluent which is discharged to Irvine Bay, Scotland. Control was achieved by means of a consent (licence) condition requiring compliance with a laboratory test of acute toxicity, which was added to the more orthodox conditions already imposed upon the discharge. The new condition was derived using the concept, explicit in the environmental quality objective/environmental quality standard approach to pollution control, of an allowable mixing zone around the outfall. The derivation and validation of the condition necessitated laboratory and field bioassay, current measurements and dye releases, and the use of a plume development model.
