BVT-Merkblatt zu Abwasser- und Abgasbehandlung

Annexes
7.7 Annex VII. Member States’ Legislation on Waste Water
and Waste Gas in the Chemical Sector
Annex VII surveys the chemical sector emission limits for waste water and waste gas in Member
States. Note that there may be different criteria behind the figures, concerning such items as
averaging time, reference conditions, sampling techniques, measurement and analysis and
method of compliance testing.
1. AUSTRIA
Emissions to Air
No special legislation exists in Austria on emission standards for air emissions from the chemical
industry. In general the “Gewerbeordnung” (BGBl. 194/1994) regulates the licensing of
chemical plants and means that plants have to be “state-of-the-art” in their performance. Emission
standards for air emissions from chemical plants are usually based on the German “Technical
Instructions on Air Quality” (TA – Luft).
Combustion plants are regulated with the “Feuerungsanlagenverordnung” (BGBl. II 1997/331),
except for steam boilers including waste heat boilers, afterburners of exhaust gases, gas turbines
and combustion engines.
Emission standards for boiler plants are regulated by the “Luftreinhaltegesetz für Kesselanlagen”
(BGBl. 1988/380 i.d.F. BGBl. 1993/185, BGBl. I 1997/115, BGBl. I 1998/158) and the
“Luftreinhalteverordnung für Kesselanlagen” (BGBl. 1989/19 i.d.F. BGBl. 1990/134, BGBl.
1994/785, BGBl. II 1997/324).
­ Feuerungsanlagenverordnung (Ordinance for Firing Installations) (BGBl. II 1997/331)
The “Feuerungsanlagenverordnung” regulates emissions of combustion plants with a nominal
thermal output of 50 kW or more. This ordinance is based on § 82 Abs. 1 of the Gewerbeordnung.
As mentioned above, steam boilers including waste heat boilers, afterburners of
exhaust gases, gas turbines, combustion engines and plants using waste as fuel are not regulated
by this ordinance.
The “Feuerungsanlagenverordnung” provides different emission standards, depending on
the fuel used and the thermal output. The emission standards for coal- and coke-firing
plants, oil-fired furnaces and combustion plants for gaseous fuels are presented in the following
section.
a) Coal- and coke-fired plants
Emission standards for furnaces using coal or coke
Pollutants Capacity a [MW]
�0.35 >0.35-1 >1–2 >2–10 >10-50 >50
Dust [mg/m³] 150 150 150 50 50 50
SO2 [mg/m³] - - - - 400 200
CO [mg/m³] 1000 1000 150 150 150 150
NOx [mg/m³] - 400 400 400 350 100
a The capacity is defined as the average of the hourly added amount of heat related to the calorific value
of the fuel
The emission standards are related to dry exhaust gas at 0 °C, a pressure of 101.3 kPa and oxygen content
of 6 % in the exhaust gas.
