Division BAT-associated emission levels
United Kingdom
The BAT-associated emission levels (BAT-AELs) for direct emissions to a receiving water body from the production of copper, lead, tin, zinc, cadmium, precious metals, nickel, cobalt and ferro-alloys are given in Table 2.
These BAT-AELs apply at the point where the emission leaves the installation.
