BVT-Merkblatt zu Abwasser- und Abgasbehandlung

Annexes
2 Toxicity unit = 100/x hour E(L)C50 in vol-%, where x is defined by the test procedure. The
toxicity of the process effluent to at least two appropriate aquatic species shall be determined.
3 No substance shall be discharged in a manner, or at a concentration which, following initial
dilution, causes tainting of fish or shellfish, interferes with normal patterns of fish migration or
accumulates in sediments or biological tissues to the detriment of fish, wildlife or their predators.
4 Within 6 months of the commencement of production (or as may be relevent on a campaign
basis), the effluent should be screened for a priority pollutant list.
5 Consent conditions for these parameters for discharge to municipal treatment plants can be
established with the licencing authority and different values may apply.
6 This limit applies only to
- manufacture of chemicals in an integrated chemical installation
- manufacture of olefins and their derivatives or of monomers and polymers, including
styrene and vinyl chloride
- manufacture, by way of chemical reaction processes, of organic or organo-metallic
chemical products
- manufacture of pesticides, pharmaceutical or veterinary products and their intermediates.
7 Where the metallic content of the effluent arises as an unavoidable contaminant of raw mate-
rials, then these limits may not apply

Emissions to Air
"Emission limit values for the containment of pollutant emissions from existing plants"
[Supplemento ordinario N. 51 alla Gazzetta Ufficiale Italiana n. 176 del 30 luglio 1990 – Serie
generale]
The emission limit values for existing plants (i.e. plants built or authorised before the approval
of the law above) are set by three Annexes:
Annex 1 reports general emission limit values
Annexes 2 and 3 list specific limits and prescriptions for the activities reported therein
Annex 4 reports sampling, analysis and emissions assessment methods
Annex 5 reports abatement techniques
Annex 6 reports diffuse emissions
Annex 7 reports fugitive emissions
Please note:
Only an extract of Annex 2 is reported in this document.
Limit emission values have not yet been set for the new plants in Italy.
ANNEX 1 (GENERAL EMISSION LIMIT VALUES):
1.1 Substances considered as carcinogenic and/or teratogenic and/or mutagenic (Table A1)
1.2 Substances with very high toxicity and bioaccumulability (Table A2)
2. Inorganic substances, preferably in the form of dust (Table B)
3. Inorganic substances, preferably in the form of gas or vapour (Table C)
4. Organic substances in the form of gas, vapour or dust (Table D)
5. Total dust
