550 kg of sulphate per tonne of titanium dioxide produced.
130 kg chloride per tonne of titanium dioxide produced using neutral rutile,
228 kg chloride per tonne of titanium dioxide produced using synthetic rutile,
330 kg chloride per tonne of titanium dioxide produced using slag. Installations discharging into salt water (estuarine, coastal, open sea) may be subject to an emission limit value of 450 kg chloride per tonne of titanium dioxide produced using slag.
6 kg per tonne of titanium dioxide produced as an annual average;
500 mg/Nm3 as an hourly average for plants for the concentration of waste acid.
5 mg/Nm3 as a daily average;
40 mg/Nm3 at any time.
The monitoring of emissions into air shall include at least the continuous monitoring of:
gaseous sulphur dioxide and trioxide discharged from digestion and calcination from plants for the concentration of waste acid in installations using the sulphate process;
chlorine from major sources within installations using the chloride process;
dust from major sources.
