2.3.3 International Regulatory Actions 



2.3.3.1 United Kingdom 



The first regulatory action in the UK to reduce the environmental impact 

 of organotin compounds from antifouling paint was announced by the 

 Environment Minister in Parliament on 24 July 1985. The action consisted 

 of the five following steps: (1) the development of regulations to 

 control the retail sale of the most damaging organotin containing paints 

 [beginning 1 January 1986, they intended to ban the use of "free 

 association" organotin-based paints by small boat owners, and to set the 

 maximum levels for the organotin content of ••copolymer" paints], (2) a 

 notification scheme for all new antifouling agents, (3) guidelines for the 

 cleaning and painting of boats coated with antifoulants, (4) propose the 

 establishment of a provisional ambient environmental quality target (EQT) 

 for the concentration of tributyltin in water [20 ng/1 was proposed as the 

 UK's EQT], and (5) coordination and further development of organotin 

 monitoring and research programs so that the Government could assess the 

 effectiveness of these regulatory actions at a later date. 



The first legislation to control the retail sale of organotin based 

 antifoulant paints was introduced on December 18, 1985, under the Control 

 of Pollution (Antifouling Paints) Regulations of 1985, which came into 

 force on 13 January 1986. These regulations were developed under Sections 

 100 and 104(1) of the Control of Pollution Act of 1974. They prohibited
