814.318.142.1 b. terrain

modifications;

c. equipment

and

machines;

d. ventilation systems which collect vehicle exhaust gases and discharge them as waste air into the environment.

Vehicles means motor vehicles, aircraft, ships and railways.

Transport infrastructure means roads, airfields, railway tracks and other installations where vehicle exhaust gases are released into the environment as waste air without being collected.

4

New installations also includes installations which are altered, extended or repaired if:

a. higher or different emissions are to be expected as a result or b. the costs incurred amount to more than half those of a new installation.

Ambient air pollution levels are excessive if one or more of the ambient limit values specified in Annex 7 is exceeded. If no such limit values are specified for a pollutant, ambient air pollution levels shall be considered excessive if: a. they endanger human beings, animals, plants or their biological communities or habitats;

b. a survey establishes that they significantly affect the well-being of a substantial proportion of the population;

c. they damage buildings or d. they harm soil fertility, vegetation or waters.

Placing on the market means the transfer or disposal for the first time, whether or not for consideration, of equipment or machines for distribution or use in Switzerland. Equivalent to placing on the market is the commissioning, for the first time, of equipment or machines at one's own enterprise in cases where placing on the market has not previously occurred.4 Chapter 2

Art. 4

Preventive limitation of emissions specified by the authorities 1

Emissions for which no limitation is specified in this Ordinance or for which a particular limitation is declared not to be applicable, shall be limited preventively by the authorities as far as is technically and operationally feasible and economically acceptable.

2

Emission limitation measures are technically and operationally feasible if they: a. have been successfully tested at comparable installations in Switzerland or abroad or

b. have been successfully applied in experiments and can be transferred to other installations from a technological perspective.

The assessment of the economic acceptability of emission limitations shall be based on an average, economically sound enterprise in the relevant sector. If a particular sector contains widely differing classes of enterprises, the assessment shall be based on an average enterprise of the relevant class.

Art. 5

Stricter limitation of emissions ordered by the authorities 1

If an individual planned installation is expected to cause excessive ambient air pollution levels even though the preventive emission limitation requirements are met, the authorities shall order additional or stricter emission limitation requirements for the installation concerned.

2

The emission limitation requirements are to be supplemented or tightened to such an extent that no excessive ambient air pollution levels are caused.

Art. 6

Capture and removal of emissions6 1 Emissions shall be captured as fully and as close to the source as possible and shall be removed in such a way as to prevent excessive ambient air pollution levels.7 2 They shall generally be discharged above roof level via stacks or waste air ducts.

3 Annex 6 applies to stacks. If the required stack height H cannot be realised, or if the parameter H0 is more than 100 m, the authorities shall as an alternative tighten the emission limitation requirements specified in Annexes 1-3.

General preventive limitation of emissions 1 Scope 1 The provisions of this Annex apply to the preventive limitation of emissions from
stationary installations.

2 They are without prejudice to the additional or different provisions applicable for: a. particular installations, as specified in Annex 2; b. combustion installations, as specified in Annex 3; c. type-approval of combustion installations, as specified in Annex 4.

2 Definitions 21 Exhaust gases

Exhaust gases means waste air, flue gases and other air pollutants discharged by installations.

22 Emissions Emissions are expressed in the following terms: a. Concentration:

Mass of emitted substance in relation to the volume of exhaust gas (e.g. in milligrams per cubic metre [mg/m3]); b. Mass

flow:

Mass of emitted substance per unit time (e.g. in grams per hour [g/h]); c. Emission

factor:

Ratio of the mass of emitted substance to the mass of the products generated or processed (e.g. in kilograms per tonne [kg/t]); d. Emission

ratio:

Ratio of the mass of an air polluting substance emitted to the mass of that substance supplied to the installation in fuels and feedstock (in % (m/m)); e. Smoke

number:

The degree of filter blackening caused by exhaust gases. The grey scale used to determine the Bacharach smoke number ranges from 0 to 9 in unit steps.

59 Revised in accordance with No II of the Ordinances of 20 Nov. 1991 (AS 1992 124), of 15 Dec. 1997 (AS 1998 223) and of 23 June 2004 (AS 2004 3561), to No II 10 of the Ordinance of 18 May 2005 on the Repeal and Amendment of Ordinances in connection with

Air Pollution Control Ordinance 21

814.318.142.1 23

Reference value for emission concentrations 1 The limit values expressed as concentrations and the oxygen contents given as reference values are based on the volume of exhaust gas under standard conditions (0°C, 1013 mbar) after deduction of the moisture content (dry).

2 The limit values expressed as emission concentrations are based on the amount of exhaust gas which is no more heavily diluted than is technically and operationally unavoidable.

3 If oxygen content by volume is given as the reference value for an installation listed in Annexes 2-4, the measured emission concentrations are to be corrected to this reference value.

24 Rated

thermal

input

The rated thermal input is the thermal energy supplied to an installation per unit time. It is obtained by multiplying the fuel consumption of the installation by the lower calorific value of the fuel.

3 General

provisions

31 Limitation of

emissions

1 The following emission limitation requirements apply: a. for dust: Number 4; b. for inorganic substances, mainly in the form of dust: Number 5; c. for inorganic substances in gaseous or vaporous form: Number 6; d. for organic substances in gaseous, vaporous or particulate form: Number 7; e. for carcinogens: Number 8.

2 Substances not listed in Numbers 5-8 shall be assigned to the substance classes which have comparable effects on the environment. Account shall be taken in particular of degradability and bio-accumulability, toxicity, the effects of decomposition processes and transformation products, and odour intensity.

Limitation of emissions dependent on installation size 1 If there is more than one emission source and if emission limitation requirements depend on the size of an installation (e.g. capacity or mass flow), the authorities shall determine which emission sources shall collectively be considered to constitute a single installation.

2 Emission sources are generally to be considered as a single installation if they are situated in close proximity to each other and if their emissions: a. essentially contain the same or similar pollutants, or

Protection of the Ecological Balance 22

814.318.142.1 b. can be reduced using the same technology.

3 Parts of an installation which only serve as back-ups in the event of malfunctions are not taken into account when determining the size of the installation.

4 Emission limit values which depend on a certain mass flow shall only apply if: a. this mass flow is reached or exceeded for more than five hours per week, or b. double this mass flow is reached or exceeded for a shorter period.

4 Dust 41

Limit value for total dust If the mass flow of dust is 0.20 kg/h or more, total dust emissions must not exceed 20 mg/m3.

Limitation of exposure to components of dust The requirements specified in Numbers 5, 7 and 8 apply for the limitation of exposure to individual components of dust.

Measures relating to treatment, storage, transshipment and transport

1 If significant dust emissions may occur in commercial or industrial facilities as a result of processes such as the conveyance, crushing, sorting or filling of dustforming materials, the dust-containing exhaust gases must be captured and fed into a dust removal system.

2 When dust-forming materials are stored or transshipped in the open, measures must be taken to prevent significant dust emissions.

3 When dust-forming materials are transported, transport equipment must be used which prevents significant dust emissions.

4 If traffic on factory roads may cause significant dust emissions, the roads must be kept free of dust.

Inorganic substances, mainly in the form of dust 51 Limit

values

1 The emission concentration of the substances listed in Number 52 must not exceed the following values: a. Class 1 substances at a mass flow of 1 g/h or more 0.2 mg/m3

b. Class 2 substances at a mass flow of 5 g/h or more 1 mg/m3

c. Class 3 substances at a mass flow of 25 g/h or more 5 mg/m3

Air Pollution Control Ordinance 23

814.318.142.1 2 The limit values apply to the total mass of an emitted substance, including gaseous and vaporous components in the exhaust gas.

Measurement and assessment of emissions 1 For each individual installation, emissions shall be measured under steady state conditions and in the load ranges which are relevant for assessment. In general, these are at least the highest and the lowest load point at which the installation is operated under standard operating conditions.

2 For installations operated with soot blowing or similar cleaning processes, dust emissions shall be measured and assessed over a half-hour period. Measurement must include the cleaning phase.

Special provisions for combustion installations comprising several individual installations 1

If several individual installations form a single operating unit, then limitation of emission for each individual installation is determined by the rated thermal input (Annex 1 Number 24) of the entire operating unit (total rated thermal input).

2

The total rated thermal input is the sum of the rated thermal inputs of all the individual installations which make up the operating unit.

3 The following are exceptions to paragraphs 1 and 2: a. individual installations with a rated thermal input of up to 1 MW, provided that one or more other individual installations forming part of the operating unit operate on the same fuels; b. individual installations with a rated thermal input of up to 10 MW, provided that no other individual installations forming part of the operating unit operate on the same fuel.

Air Pollution Control Ordinance 81

814.318.142.1 Annex 693

(Art. 6 para. 3)

Minimum stack height 1 Scope
The provisions of this Annex apply to installations for which the quantity Q/S exceeds 5, where: Q = mass flow of the emitted air pollutant in grams per hour; S =

value calculated in accordance with Number 9.

2 Calculation method

The required physical stack height is calculated step by step in accordance with Numbers 3 to 6.

2

If more than one air pollutant is emitted, the physical stack height is calculated on the basis of the pollutant for which the quantity Q/S has the highest value.

3 Parameter

Determination of H0 according to Diagram 1 1

The parameter H0 takes account of the short-term effects of the air pollutants emitted from a single installation. It is determined with the aid of Diagram 1.

2

The quantities Q and F depend on the emission conditions at the installation. The full load values and the fuel/emission conditions most conducive to air pollution are used to calculate H0.

3

The quantity S is used to limit the maximum short-term ambient air pollution levels caused by the installation to a specific value (S value). The S values specified in Number 9 are used to calculate H0.

Determination of H0 in individual cases 1

The parameter H0 is determined in individual cases according to the recognised rules for calculating the stack height and the dispersion of flue gases if: a. the Q/S or F values lie outside Diagram 1 or b. the flue gas temperature is less than 55°C.

93 Corrected in accordance with No II of the Ordinance of 15 Dec. 1997, in force since 1 March 1998 (AS 1998 223).

Protection of the Ecological Balance 82

814.318.142.1 2

However, where flue gas temperatures are below 55°C, the parameter H0 must not be lower than the value which is obtained according to Diagram 1 for a temperature of 55°C.

Minimum height for flat, obstacle-free terrain 1

The stack height for flat, obstacle-free terrain is H1 = f x H0

The correction factor f takes account of long-term effects due to wind channelling.

2

Values between 1.0 and 1.5 are used for f as follows: f =

1.00 for sites with no prevailing wind direction; f =

1.25 for sites with average conditions; f =

1.50 for valleys with pronounced wind channelling.

Intermediate values are also possible for f, depending on the site conditions.

Height increase for buildings and vegetation Elevated objects (buildings and vegetation) in the vicinity of the stack are taken into account by means of a height increase I1: I1 = g x I where: I = Height of the highest significant obstacle area in the region affected by the installation. Values between 0 (no obstacles) and 30 m (e.g. forest) are used for I.

g =

Correction factor, with values between 0 and 1 according to Diagram 2.

Physical stack height The physical stack height H is calculated according to the following formula: H = H1 + I1 7

More stringent requirements In justified cases, the authorities will require taller stacks, for example, in the case of: a. structures with particular shapes; b sites with particularly poor meteorological dispersion conditions; c. particular topographical conditions, such as narrow valleys, hillsides or depressions.
