According to the Scottish Environmental Protection Agency (SEPA) the atrazine Emission Reporting Threshold is as follows:
10.0 Kg/yr Pollutant Emissions to Air
0.05 Kg/yr Pollutant Emissions to Water
0.05 Kg/yr Pollutant Emissions to Waste Water
1.00 Kg/yr Pollutant Emissions to Land
Releases of Atrazine are controlled through the UK Pollution, Prevention and Control (PPC) Regulations and the UK Surface Waters (Dangerous Substances) Regulations (SI 1997/2560). Atrazine is also regulated as a pesticide through the Food and Environmental Protection Act (FEPA 1985) and the Control of Pesticides Regulations (COPR 1986). in the UK, throughout the evaluation process, the ACP and the Ministry of Agriculture made a point of stressing that restrictions imposed on atrazine are not the result of any health risk, but only to keep residue levels in water within the legally imposed EC Drinking Water Directive limit of 0.1 µg/l for any single pesticide, a level which was not a level derived from toxicological studies.
