based on Articles 35a and 35c of the Environmental Protection Act of 7 October 1983¹ (EPA),

ordains:

Section 1 General Provisions

Art. 1 Definition

For the purpose of this Ordinance, volatile organic compounds (VOCs) are organic compounds with a vapour pressure of at least 0.1 mbar at 20 °C or a boiling point of maximum 240 °C at 1013.25 mbar.

Art. 2 Object of taxation

The following are liable for tax:

VOCs on the positive list of substances (Annex 1);
VOCs according to letter a that are contained in products mentioned in the positive list of products (Annex 2).

Art. 3 Application of customs legislation

Customs legislation applies by analogy to the levying and refund of the tax, and to the procedure where imports and exports are concerned.

Section 2 Implementation

Art. 4² Implementing authorities

The Directorate General of Customs shall implement this Ordinance unless the Federal Office for the Environment (FOEN) is responsible. In doing so, it shall take account of the views of the FOEN.

The FOEN:

implements the provisions on the distribution of the tax revenue (Art. 23–23b);
supports the Directorate General of Customs in implementing the tax exemption provisions in cases of measures taken to reduce emissions (Art. 9–9h);
evaluates the effect on air quality of the tax and the exemption from tax in cases of measures taken to reduce emissions and publishes the results regularly.

The Federal Office for Customs and Border Security³ shall provide the FOEN with the required documents.

The cantons shall support the implementing authorities, unless the Confederation is liable to the tax. In particular, they shall review:

the measures plans in accordance with Article 9d and revisions made to the same (Art. 9f and 9g);
the proof in accordance with Article 9h;
the VOC balance sheets in accordance with Article 10;
⁴the request for an extension of the deadline in accordance with Article 9i.

The implementing authorities shall together receive 1.5 per cent of the total revenues (gross proceeds) in compensation for the costs they incur.

In consultation with the Federal Department of Finance, the Federal Department of Environment, Transport, Energy and Communications (DETEC) shall issue regulations on compensatory payments to the cantons for their support in implementing this Ordinance.

Art. 5⁵ Commission of experts for the incentive tax on VOCs

The Federal Council shall establish a commission of experts, on which the Confederation, the cantons and other interested parties are represented, and shall appoint a representative of the FOEN⁶ as president. The commission of experts shall consist of a maximum of twelve members.

The commission of experts shall advise the Confederation and the cantons on matters relating to the incentive tax on VOCs, in particular on the amendment of the Annexes and on the implementation of the exemption from tax in cases of measures taken to reduce emissions.⁷

Art. 6 Audits

The implementing authorities may, without prior notice, carry out audits, in particular of persons who are required to pay the tax, and of persons required to prepare a VOC balance sheet or who submit a request for refund.

All information and documents necessary for the implementation of this Ordinance must be submitted to the implementing authorities on request.

Section 3 Tax rate

Art. 7⁸

The tax rate amounts to 3 Swiss francs per kilogram of VOCs.

Section 4 Exemption from Tax and VOC Balance Sheet

Art. 8 Exemption from tax in cases of negligible quantities

VOCs in the following mixtures and products are exempt from tax:

mixtures and products in which the VOC content does not exceed 3 per cent (per cent by weight);
mixtures and products manufactured in Switzerland that are not on the positive list of products.

If mixtures and products under paragraph 1 letter a are imported, the tax is not levied.

If mixtures and products according to paragraph 1 letters a and b are manufactured in Switzerland, the VOCs contained therein are exempted from tax at the request of the manufacturer.

Art. 9⁹ Exemption from tax in cases of measures taken to reduce emissions

VOCs that are used in stationary installations in terms of Article 2 paragraph 1 and Annex 1 Number 32 of the Ordinance on Air Pollution Control of 16 December 1985¹⁰ (OAPC) are exempt from the tax if:

the measures taken have resulted in the annual quantity of VOC emissions from these installations being reduced by at least 50 per cent of the VOC emissions quantity allowed for the same rate of production while complying with the preventive emission limits set by Articles 3 and 4 of the OAPC;
the air purification plant (APP) used therefor is in a good technical condition and is operational for 95 per cent of the operating time; and
the VOC emissions of the stationary installation that are not processed by the APP (diffuse VOC emissions) are reduced in accordance with Annex 3.

Art. 9a¹¹ Installation groups

Two or more stationary installations may on application be combined as an installation group if:

they are operated by the same person; and
each installation meets the requirements of the OAPC.¹²

An installation group is treated in the same way as a single stationary installation with regard to meeting the exemption requirements set out in Article 9.

The composition of an installation group may not be changed during the period mentioned in Article 9c paragraph 1 letter b. Exempted therefrom are:

the exclusion of decommissioned stationary installations;
the subsequent inclusion of newly commissioned stationary installations;
the subsequent inclusion of stationary installations that already meet the requirements set out in Annex 3.¹³

If laboratories whose VOC emissions are not processed by an APP are included in an installation group, they must meet the requirements set out in Annex 3 from the time of their inclusion.¹⁴

Art. 9b¹⁵ Exceptional events and replacement of the APP

If the operational targets for the APP required under Article 9 paragraph 1 letter b are not achieved over a financial year due to an exceptional event, the VOCs emitted outside the downtime of the APP are exempt from the tax provided:

the exemption requirements set out in Article 9 are met outside the downtime;
the cantonal authority was informed immediately of the exceptional event; and
the exceptional event was not caused by the inadequate maintenance or incorrect operation of the APP.

If the operational targets for the APP required under Article 9 paragraph 1 letter b are not achieved over a financial year due to the replacement of the APP, the VOCs emitted outside the downtime of the APP are exempt from the tax provided:

the exemption requirements set out in Article 9 are met outside the period during which the APP was being replaced;
the cantonal authority is informed in advance of the planned downtime of the APP; and
the replacement work is carried out during the company holidays or at times of low production.

Art. 9c¹⁶ Reduction of diffuse VOC emissions

Article 9 paragraph 1 letter c is fulfilled, if:

the stationary installation already meets the requirements set out in Annex 3; or
¹⁷the diffuse VOC emissions are reduced in accordance with the measures plan approved by the Directorate General of Customs to the extent that the stationary installation fulfils the requirements set out in Annex 3 by 31 December 2022 (the operating period) at the latest.

The DETEC shall revise Annex 3 and the operating period under paragraph 1 letter b every five years after consulting the industries and cantons concerned. In doing so, it shall take account of technical developments.

Art. 9d¹⁸ Measures plan

The measures plan under Article 9c paragraph 1 letter b shall comprise:

information on the extent to which the requirements set out in Annex 3 (target-versus-actual analysis) have been met;
the planned measures;
the planned schedule for implementing the measures;
the emissions reduction potential of each measure.

It must provide that a minimum of half of the planned emissions reductions are met in the first three years of its duration.

Art. 9e¹⁹ Application for approval of the measures plan

The application for approval of the measures plan for an existing stationary installation must be submitted to the cantonal authority by 30 April of the year before the beginning of the tax exemption at the latest.

For a new stationary installation, the application for approval of the measures plan may be submitted to the cantonal authority at any time.

The application must include the measures plan.

Operators of existing stationary installations who must submit a VOC balance sheet under Article 10 must include this with the measures plan.

Art. 9f²⁰ Revision of the measures plan in the case of measures with equivalent effect

The approved measures plan may be revised on application if one or more measures can be replaced by other measures with at least the equivalent effect.

The application for revision must be submitted to the cantonal authority six months at the latest before the beginning of the financial year in which it is planned to implement the revised measures plan.

Art. 9g²¹ Revision of the measures plan in the event of modifications to the stationary installation

Modifications to the stationary installation that affect the diffuse VOC emissions must be reported to the cantonal authority immediately.

If necessary, the measures plan shall be revised.

Art. 9h²² Proof required for the tax exemption in cases of measures taken to reduce emissions

Any person who claims a tax exemption under Article 35a paragraph 4 EPA must prove each year that the exemption requirements set out in Article 9 have been met. In particular, it must be shown that:

the stationary installation satisfies the requirements set out in Annex 3; or
²³the measures contained in the approved measures plan for the financial year concerned have been implemented on schedule and the stationary installation fulfils the other requirements set out in Annex 3.

The proof must be submitted at the same time as the VOC balance sheet.

If the proof cannot be provided, the tax exemption ceases to apply to the VOCs used in the stationary installation during the relevant financial year.

Art. 9i²⁴ Extension of the deadline in hardship cases

In response to a request, the Directorate General of Customs may extend the deadlines for implementing the measures in the measures plan in accordance with Article 9d until no later than the end of the operating period if the viability of the undertaking in which the installation is operated would through no fault of its own be jeopardised by implementing the measures within the deadline.

The request for an extension of the deadline must contain the following information in particular:

the fundamental change that has occurred since approval of the measures plan that would jeopardise viability if the measures are implemented within the deadline, and its effects on the undertaking;
proof that the fundamental change in terms of letter a has occurred through no fault of the undertaking;
all measures already taken to reduce diffuse VOC emissions in the stationary installation concerned;
the anticipated costs of each measure to be postponed;
the schedule for implementing the measures to be postponed.

The Directorate General of Customs may require further information to be provided.

The request must be submitted to the cantonal authority no later than four months before the end of the financial year concerned.

Art. 9j²⁵ Date of exemption in the case of new stationary installations

New stationary installations that meet the requirements for an exemption under Article 9 become exempt from the tax from the following dates:

if the stationary installation already satisfies the requirements of Annex 3: on coming into operation;
if the stationary installation does not yet satisfy the requirements of Annex 3: from the financial year following the year in which the application for approval of the measures plan is submitted.

Art. 10 VOC balance sheet

Any person who claims an exemption from the tax in accordance with Article 35a paragraph 3 letter c or paragraph 4 of the EPA or an authorisation to obtain VOCs provisionally exempted from the tax (Art. 21) shall keep VOC accounts and prepare a VOC balance sheet.²⁶

A VOC balance sheet shall contain:

entries, stocks, outgoings;
quantities contained in mixtures and products;
quantities recovered;
quantities eliminated in the enterprise or through an external enterprise, or quantities transformed;
remaining emissions.

The Directorate General of Customs may request further information.

The VOC balance sheet must be prepared on an official form. The Directorate General of Customs may accept other manners of presentation.

If the cost of preparing VOC balance sheets is disproportionately high, the Directorate General of Customs may grant exceptions to paragraphs 1 and 2.

Section 5 Collection of Tax within Switzerland

Art. 11 Registration

Persons who produce VOCs must report to the Directorate General of Customs, which shall maintain a register.

Art. 12 Origin of the tax demand

A tax demand is made:

for VOCs produced within Switzerland, at the moment when they leave the manufacturer, or are used by the manufacturer;
for VOCs subject to subsequent payment of the tax under Article 22 paragraph 2, at the moment when the beneficiary uses the VOCs, or passes them on to a third party.

Art. 13 Tax declaration

Manufacturers who place VOCs on the market or use them themselves, as well as persons who supply VOCs wholesale and possess an authorisation to obtain VOCs provisionally exempted from the tax (Art. 21 para. 2) must submit a tax declaration to the Directorate General of Customs by the 25th day of the month following the origin of the tax demand.²⁷

Art. 17 Prescription of the tax demand

The tax demand shall prescribe ten years after the end of the calendar year in which it originated.

The prescriptive period shall be interrupted:

if the tax payer acknowledges the tax demand;

The tax demand prescribes in every case fifteen years after the end of the calendar year in which it originated.

Section 6 Refund of Tax

Art. 18 Requirements for refund

Tax is refunded only if the entitled persons prove that they have used the VOCs in such a way that these are exempt from the tax.²⁹

Entitled persons must retain all documents necessary for the justification of a refund for five years after submitting a refund request.

to use or handle at least 50 t of VOCs per annum in such a way that they are not released to the environment; or
to export at least 50 t of VOCs per annum.³⁴

…³⁵

It may also grant this authorisation to persons who use a substance listed in Annex 1 of this Ordinance if they prove that:

this substance amounts to at least 55 per cent of their entire consumption of VOCs;
they use at least 1 tonne of this substance each year; and
due to chemical transformation caused by the process for using the substance, on average no more than 2 per cent of the substance is released to the environment.³⁶

Authorisation may also be granted to persons who deal wholesale in VOCs and prove average stocks of at least 25 t of VOCs or an annual minimum turnover of 50 t of VOCs.³⁷

The formal commitment or the proof must be submitted to the Directorate General of Customs.

The Directorate General of Customs shall maintain a public register of persons who have been authorised to acquire provisionally exempted VOCs.³⁸

Art. 22 Account

Holders of an authorisation under Article 21 must submit the VOC balance sheet to the cantonal authorities no later than six months after the end of the financial year.

.…³⁹

Documents relating to the procedure for obtaining VOC provisionally exempt from tax must be retained for five years after submission of the VOC balance sheet.⁴⁰

Art. 22a⁴¹ Correcting the customs declaration

Any person required to make a customs declaration who applies for a new customs assessment in accordance with Article 34 paragraph 3 of the Customs Act of 18 March 2005⁴² must prove that an authorisation to obtain VOCs provisionally exempt from tax existed at the time of the original customs declaration.

Art. 22b⁴³ Errors in the submission of VOC balance sheet

If the VOC balance sheet is incomplete or has not been submitted on time, authorisation in accordance with Article 21 shall be suspended for three years from the beginning of the next financial year.

The Directorate General of Customs shall allow a grace period within which to resubmit a complete VOC balance sheet.

Interest shall be charged on the taxes due in accordance with Art. 22 paragraph 2 on the basis of the balance sheet submitted during the grace period. The charging of interest begins on expiry of the submission deadline in accordance with Art. 22 paragraph 1.

If the resubmission deadline in accordance with paragraph 2 expires without resubmission being made, the Directorate General of Customs shall assess the tax due in accordance with due discretion and taking account of outgoings taxed in previous years.

Section 8 Distribution of Revenue from the Tax

Art. 23⁴⁴ Principle

The insurers shall distribute the revenue from the tax to the population as instructed by and under the supervision of the Federal Office.

The distribution shall be carried out in the next year but one (the year of distribution) based on the annual revenue from the tax obtained in the year of collection.

The annual revenue from the tax corresponds to the revenue collected by 31 December including interest.

The insurers are as follows:

insurers providing mandatory health insurance in accordance with the Federal Act of 18 March 1994⁴⁵ on Health Insurance (HIA);
the military insurance fund in accordance with the Federal Act of 19 June 1992⁴⁶ on Military Insurance (MIA).

The insurers shall distribute the annual revenue in equal parts to all those who, in the year of distribution:

are required to insure themselves in terms of the HIA or of Article 2 paragraph 1 or 2 MIA; and
are domiciled or habitually resident in Switzerland.

Persons who are insured for only part of the distribution year shall be entitled to a deduction pro rata temporis.⁴⁷

The insurers shall offset the amounts against the premiums due in the distribution year.⁴⁸

Art. 23a⁴⁹ Disbursement to the insurers

The annual revenue shall be disbursed to the insurers proportionately by 30 June of each distribution year.

The share paid to each insurer is calculated on the basis of the number of persons that it has insured who meet the requirements of Article 23 paragraph 5 on 1 January of the distribution year.

The difference between the share disbursed and the sum of the amounts actually distributed will in each case be settled in the following year.

Art. 23b⁵⁰ Organisation

Each insurer shall report the following to the Federal Office of Public Health by 20 March of the distribution year:

the number of persons that it insures that meet the requirements of Article 23 paragraph 5 as of 1 January of the distribution year;
the sum actually distributed in the previous year.

The insurers shall inform the insured persons of the amount to be distributed when notifying them of the new premium for the distribution year. In addition, they must send the insured person a factsheet written by the FOEN on the procedure for redistribution.⁵¹

Art. 23c⁵² Compensation for the insurers

Compensation for the insurers is governed by Article 123 of the CO₂Ordinance of 30 November 2012⁵³.

Reduction of Diffuse VOC Emissions

(Art. 9 let. c)

1 Requirements for the operation of stationary installations

11 General requirements

111 Principle

All VOC relevant processes must be optimised with a view to reducing diffuse VOC emissions.

112 Exhaust air collection and purification

¹ Processes must be conducted in closed systems, provided this is technically and operationally possible and economically acceptable.

² The exhaust air from closed systems must be processed by the APP.

³ In the case of processes in non-closed systems, the exhaust air must be processed by the APP via suction hoods or shape-adapted source extractors with appropriate suction capacity either directly or following concentration.

⁴ Room exhaust air must be processed by the APP directly or following concentration.

⁵ The exhaust air under paragraphs 2–4 must be processed by the APP after production has been completed (APP stopping time).

⁶ Paragraphs 3–5 do not apply if it is established that the exhaust air due to its negligible VOC concentration is unlikely to be processed by the APP.

⁷ There must be an up-to-date maintenance plan for the exhaust air system, which in particular sets out how it is guaranteed that:

the exhaust air system is airtight;
components that are essential to the system are quickly replaced.

⁸ The ventilation in working spaces with mechanically generated incoming air must be operated, provided this is technically and operationally possible and economically feasible, so that negative pressure is maintained if:

a production building has only one working space and this emits an annual load at least 500 kg of VOCs;
a production building has several working spaces and they emit an annual total load of at least 1000 kg of VOCs; or
a production building has several working spaces and one of these working spaces emits an annual load of at least 500 kg of VOCs.

113 Container caps

Containers for VOCs must be fitted with suitable caps.

114 Work organisation

¹ Up-to-date working regulations must be provided regulating the low-emission handling of solvents. Regulations must also be provided on how to deal with leakages of solvents.

² Employees must be trained regularly in how to apply the working regulations.

³ Compliance with working regulations must be verified regularly.

115 Documentation

¹ An up-to-date inventory of the sources of diffuse VOC emissions and the intake and exhaust air flows must be provided. This contains in particular:

a ventilation plan;
a quantitative estimate of the emissions from each source.

² Diffuse VOC emissions must be justified.

12 Process-specific requirements

Processes	Requirements
– Filling and decanting processes	– If technically and operationally possible and economically acceptable: vapour recovery system – Otherwise: exhaust air by means of suction hoods or shape-adapted source extractions with appropriate suction capacity via APP
– Mixtures of substances	– In the case of closed mixing installations: solvent supply via closed system – In other mixing processes: equip container with border sealed cover; exhaust air from penetrations by means of suction hoods or shape-adapted source extractions with appropriate extraction capacity via APP
– Drying and stoving when printing, laminating and coating	– In the closed system
– Cleaning of containers, products and components^a and general cleaning	– Cleaning if technically possible with water or VOC-free detergents. If VOCs are used, the following requirements apply: – If cleaning is carried out several times a week, cleaning may only take place in closed systems with (external) preparation of the waste solvents – Opening of the cleaning system to remove the cleaned container, products and components must be synchronised with the starting extraction via the ALURA so that no VOC emissions escape into the working space or into the environment – Open manual cleaning and drying only in closed spaces with exhaust air via APP; forced closure of the cover of the cleaning tank immediately after cleaning – Store cleaning utensils contaminated with solvents in sealed containers
– Storage	– In sealed containers or in the closed system; pressure balance with exhaust air via APP or back-pressure valve
– Disposal	– Pipeline to waste disposal centre or by means of closed containers
When using halogenated VOCs, Annex 2 No 87 OAPC must be complied with.

13 Equivalent requirements

The requirements in terms of this Annex may on request be replaced by other requirements provided diffuse VOC emissions are thereby reduced at least to the same extent.

2 Industry-specific guidelines

¹ The FOEN shall issue industry-specific guidelines in order to specify the requirements in terms of this Annex. These may lay down additional industry-specific requirements.

² It shall review the guidelines every five years.

³ When issuing or reviewing the guidelines, it shall consult the industries and cantons concerned and take account of technical developments.
