Annexes
§ 5. At the establishment, the necessary provisions must be present to prevent fire extinguishing
water contaminated with chemicals from draining into the ground, public sewers, surface or
groundwater. The collected contaminated fire extinguishing water must be disposed of in an
appropriate fashion. The collection capacity for contaminated fire extinguishing water must be
determined in consultation with the authorised fire brigade.
§ 6. All persons and staff working at the establishment must be fully aware of the nature of the
substances and products manufactured and the dangers involved. Personnel must be well informed
about the measures to be taken when irregularities occur. The operator is to provide upto-date
instructions as required. These instructions must be evaluated by the operator at least
once per year.
Art. 5.7.1.4
§ 1. Unless specified otherwise in the environmental licence and as a derogation from the general
emission limit values specified in chapter 4.4, the emission limit values given below - expressed
in mg/Nm 3 and relating to the following circumstances: temperature 0 °C, pressure
101.3 kPa, dry gas, or wet gas if steam ejectors are used - apply to the waste gases discharged:
The quantities of air supplied to a part of the installation for the dilution or cooling of the waste
gas are not taken into account with the calculation of the emission values.
1. propenenitrile:
� in the gaseous effluent of the combustion plants for the production of propenenitrile, irrespective
of the mass flow: 0.2 mg/Nm 3
� remaining, with a mass flow of 25 g/h or more: 5.0 mg/Nm 3
2. the following organic substance, at a mass flow per substance of 100 g/h or more:
1,2-dichloroethane:
� with the production of this compound: 5.0 mg/Nm 3
� in other cases: 20.0 mg/Nm 3
3. total dust:
plants for the production of biocides or active ingredients thereof, at a mass flow of 25 g/h or
more:
� for highly toxic or highly bioaccumulative and persistent biocides: 5.0
mg/Nm³
� for highly toxic, harmful or corrosive biocides: 20.0 mg/Nm³
� for non-harmful biocides: 100.0
mg/Nm³
§ 2. Gaseous effluents are to be collected at the place they originate and, after any necessary
purification for compliance with the prevailing emission and immission conditions, discharged
into the ambient air through a chimney stack. This chimney stack must be sufficiently tall to,
from an environmental perspective, adequately disperse the discharged substances and not affect
public health. The minimum height must be determined in accordance with the chimney
stack height calculation system as specified in art. 4.4.2.3.
