Protocol on Acidification, Eutrophication and Ground-Level Ozone (1999)

The Parties,

Determined to implement the Convention on Long-range Transboundary Air Pollution,

Aware that nitrogen oxides, sulphur, volatile organic compounds and reduced nitrogen compounds have been associated with adverse effects on human health and the environment,

Concerned that critical loads of acidification, critical loads of nutrient nitrogen and critical levels of ozone for human health and vegetation are still exceeded in many areas of the United Nations Economic Commission for Europe’s region,

Concerned also that emitted nitrogen oxides, sulphur and volatile organic compounds, as well as secondary pollutants such as ozone and the reaction products of ammonia, are transported in the atmosphere over long distances and may have adverse transboundary effects,

Recognizing that emissions from Parties within the United Nations Economic Commission for Europe’s region contribute to air pollution on the hemispheric and global scales, and recognizing the potential for transport between continents and the need for further study with regard to that potential,

Recognizing also that Canada and the United States of America are bilaterally negotiating reductions of emissions of nitrogen oxides and volatile organic compounds to address the transboundary ozone effect,

Recognizing furthermore that Canada will undertake further reductions of emissions of sulphur by 2010 through the implementation of the Canada-wide Acid Rain Strategy for Post-2000, and that the United States is committed to the implementation of a nitrogen oxides reduction programme in the eastern United States and to the reduction in emissions necessary to meet its national ambient air quality standards for particulate matter,

Resolved to apply a multi-effect, multi-pollutant approach to preventing or minimizing the exceedances of critical loads and levels,

Taking into account the emissions from certain existing activities and installations responsible for present air pollution levels and the development of future activities and installations,

Aware that techniques and management practices are available to reduce emissions of these substances,

Resolved to take measures to anticipate, prevent or minimize emissions of these substances, taking into account the application of the precautionary approach as set forth in principle 15 of the Rio Declaration on Environment and Development,

Reaffirming that States have, in accordance with the Charter of the United Nations and the principles of international law, the sovereign right to exploit their own resources pursuant to their own

environmental and developmental policies, and the responsibility to ensure that activities within their jurisdiction or control do not cause damage to the environment of other States or of areas beyond the limits of national jurisdiction,

Conscious of the need for a cost-effective regional approach to combating air pollution that takes account of the variations in effects and abatement costs between countries,

Noting the important contribution of the private and non-governmental sectors to knowledge of the effects associated with these substances and available abatement techniques, and their role in assisting in the reduction of emissions to the atmosphere,

Bearing in mind that measures taken to reduce emissions of sulphur, nitrogen oxides, ammonia and volatile organic compounds should not constitute a means of arbitrary or unjustifiable discrimination or a disguised restriction on international competition and trade,

Taking into consideration best available scientific and technical knowledge and data on emissions, atmospheric processes and effects on human health and the environment of these substances, as well as on abatement costs, and acknowledging the need to improve this knowledge and to continue scientific and technical cooperation to further understanding of these issues,

Noting that under the Protocol concerning the Control of Emissions of Nitrogen Oxides or their Transboundary Fluxes, adopted at Sofia on 31 October 1988, and the Protocol concerning the Control of Emissions of Volatile Organic Compounds or their Transboundary Fluxes, adopted at Geneva on 18 November 1991, there is already provision to control emissions of nitrogen oxides and volatile organic compounds, and that the technical annexes to both those Protocols already contain technical guidance for reducing these emissions,

Noting also that under the Protocol on Further Reduction of Sulphur Emissions, adopted at Oslo on 14 June 1994, there is already provision to reduce sulphur emissions in order to contribute to the abatement of acid deposition by diminishing the exceedances of critical sulphur depositions, which have been derived from critical loads of acidity according to the contribution of oxidized sulphur compounds to the total acid deposition in 1990,

Noting furthermore that this Protocol is the first agreement under the Convention to deal specifically with reduced nitrogen compounds,

Bearing in mind that reducing the emissions of these substances may provide additional benefits for the control of other pollutants, including in particular transboundary secondary particulate aerosols, which contribute to human health effects associated with exposure to airborne particulates,

Bearing in mind also the need to avoid, in so far as possible, taking measures for the achievement of the objectives of this Protocol that aggravate other health and environment-related problems,

Noting that measures taken to reduce the emissions of nitrogen oxides and ammonia should involve consideration of the full biogeochemical nitrogen cycle and, so far as possible, not increase emissions of reactive nitrogen including nitrous oxide which could aggravate other nitrogen-related problems,

Aware that methane and carbon monoxide emitted by human activities contribute, in the presence of nitrogen oxides and volatile organic compounds, to the formation of tropospheric ozone, and

Aware also of the commitments that Parties have assumed under the United Nations Framework Convention on Climate Change,

Have agreed as follows:

Annex I

CRITICAL LOADS AND LEVELS I. CRITICAL LOADS OF ACIDITY A. For Parties within the geographical scope of EMEP

1. Critical loads (as defined in article 1) of acidity for ecosystems are determined in accordance with the Convention’s Manual on methodologies and criteria for mapping critical levels/loads and geographical areas where they are exceeded. They are the maximum amount of acidifying deposition an ecosystem can tolerate in the long term without being damaged. Critical loads of acidity in terms of nitrogen take account of within-ecosystem nitrogen removal processes (e.g. uptake by plants). Critical loads of acidity in terms of sulphur do not. A combined sulphur and nitrogen critical load of acidity considers nitrogen only when the nitrogen deposition is greater than the ecosystem nitrogen removal processes. All critical loads reported by Parties are summarized for use in the integrated assessment modelling employed to provide guidance for setting the emission ceilings in annex II.

B. For Parties in North America

2. For eastern Canada, critical sulphur plus nitrogen loads for forested ecosystems have been determined with scientific methodologies and criteria (1997 Canadian Acid Rain Assessment) similar to those in the Convention’s Manual on methodologies and criteria for mapping critical levels/loads and geographical areas where they are exceeded. Eastern Canada critical load values (as defined in article 1) of acidity are for sulphate in precipitation expressed in kg/ha/year. Alberta in western Canada, where deposition levels are currently below the environmental limits, has adopted the generic critical load classification systems used for soils in Europe for potential acidity. Potential acidity is
defined by subtracting the total (both wet and dry) deposition of base cations from that of sulphur and nitrogen. In addition to critical loads for potential acidity, Alberta has established target and monitoring loads for managing acidifying emissions.

3. For the United States of America, the effects of acidification are evaluated through an assessment of the sensitivity of ecosystems, the total loading within ecosystems of acidifying compounds, and the uncertainty associated with nitrogen removal processes within ecosystems.

4. These loads and effects are used in integrated assessment modelling and provide guidance for setting the emission ceilings and/or reductions for Canada and the United States of America in annex II.

II. CRITICAL LOADS OF NUTRIENT NITROGEN

For Parties within the geographical scope of EMEP

5. Critical loads (as defined in article 1) of nutrient nitrogen (eutrophication) for ecosystems are determined in accordance with the Convention’s Manual on methodologies and criteria for mapping critical levels/loads and geographical areas where they are exceeded. They are the maximum amount of eutrophying nitrogen deposition an ecosystem can tolerate in the long term without being damaged. All critical loads reported by Parties are summarized for use in the integrated assessment modelling employed to provide guidance for setting the emission ceilings in annex II.

III. CRITICAL LEVELS OF OZONE

A. For Parties within the geographical scope of EMEP

6. Critical levels (as defined in article 1) of ozone are determined to protect plants in accordance with the Convention’s Manual on methodologies and criteria for mapping critical levels/loads and geographical areas where they are exceeded. They are expressed as a cumulative exposure over a threshold ozone concentration of 40 ppb (parts per billion by volume). This exposure index is referred to as AOT40 (accumulated exposure over a threshold of 40 ppb). The AOT40 is calculated as the sum of the differences between the hourly concentration (in ppb) and 40 ppb for each hour when the concentration exceeds 40 ppb.

7. The long-term critical level of ozone for crops of an AOT40 of 3000 ppb.hours for May-July (used as a typical growing season) and for daylight hours was used to define areas at risk where the critical level is exceeded. A specific reduction of exceedances was targeted in the integrated assessment modelling undertaken for the present Protocol to provide guidance for setting the emission ceilings in annex II. The long-term critical level of ozone for crops is considered also to protect other plants such as trees and natural vegetation. Further scientific work is under way to develop a more differentiated interpretation of exceedances of critical levels of ozone for vegetation.

8. A critical level of ozone for human health is represented by the WHO Air Quality Guideline level for ozone of 120 ^g/m3 as an 8-hour average. In collaboration with the World Health Organization’s Regional Office for Europe (WHO/EURO), a critical level expressed as an AOT60 (accumulated exposure over a threshold of 60 ppb), i.e. 120 ^g/m3, calculated over one year, was adopted as a surrogate for the WHO Air Quality Guideline for the purpose of integrated assessment modelling. This was used to define areas at risk where the critical level is exceeded. A specific reduction of these exceedances was targeted in the integrated assessment modelling undertaken for the present Protocol to provide guidance for setting the emission ceilings in annex II.

B. For Parties in North America

9. For Canada, critical levels of ozone are determined to protect human health and the environment and are used to establish a Canada-wide Standard for ozone. The emission ceilings in annex II are defined according to the ambition level required to achieve the Canada-wide Standard for ozone.

10. For the United States of America, critical levels of ozone are determined to protect public health with an adequate margin of safety, to protect public welfare from any known or expected adverse effects, and are used to establish a national ambient air quality standard. Integrated assessment modelling and the air quality standard are used in providing guidance for setting the emission ceilings and/or reductions for the United States of America in annex II.

Sampling and analysis of all pollutants, as well as reference measurement methods to calibrate any measurement system, shall be carried out according to the standards laid down by the European Committee for Standardization (CEN) or by the International Organization for Standardization (ISO). While awaiting the development of CEN or ISO standards, national standards shall apply;

(c) If measurements of emissions of NMVOCs are required, they should be carried out continuously if emissions of NMVOCs exceed 10 kg of total organic carbon (TOC)/h in the exhaust duct downstream from an emission reduction installation and the hours of operation exceed 200 hours a year. For all other installations, discontinuous measurement is required as a minimum. For the approval of compliance, own approaches may be used provided that they result in equal stringency;

6. For the source categories listed in paragraphs 9 to 21 below, the following revisions are relevant:

(a) Instead of applying the limit values for installations set out below, the operators of the respective installations may be allowed to use a reduction scheme (see appendix II to the present annex). The purpose of a reduction scheme is to give the operator the possibility to achieve by other means emission reductions equivalent to those achieved if given limit values were to be applied; and

(b) For fugitive emissions of NMVOCs, the fugitive emission values set out below shall be applied as a limit value. However, where it is demonstrated to the satisfaction of the competent authority that for an individual installation this value is not technically and economically feasible, the competent authority may exempt that installation provided that significant risks to human health or the environment are not expected. For each derogation, the operator must demonstrate to the satisfaction of the competent authority that the best available technique is used.

Appendix I

SOLVENT MANAGEMENT PLAN

Introduction

1. This appendix to the annex on limit values for emissions of non-methane volatile organic compounds (NMVOCs) from stationary sources provides guidance on carrying out a solvent management plan. It identifies the principles to be applied (para. 2), provides a framework for the mass balance (para. 3) and provides an indication of the requirements for verification of compliance (para. 4).

Principles

2. The solvent management plan serves the following purposes:

(a) Verification of compliance, as specified in the annex; and

(b) Identification of future reduction options.

Definitions

3. The following definitions provide a framework for the mass balance exercise:

(a) Inputs of organic solvents:

11. The quantity of organic solvents or their quantity in preparations purchased that are used as input into the process in the time frame over which the mass balance is being calculated.

12. The quantity of organic solvents or their quantity in preparations recovered and reused as solvent input into the process. (The recycled solvent is counted every time it is used to carry out the activity.)

(b) Outputs of organic solvents:

01. Emission of NMVOCs in waste gases.

02. Organic solvents lost in water, if appropriate taking into account waste-water treatment when calculating O5.

03. The quantity of organic solvents that remains as contamination or residue in output of products from the process.

04. Uncaptured emissions of organic solvents to air. This includes the general ventilation of rooms, where air is released to the outside environment via windows, doors, vents and similar openings.

05. Organic solvents and/or organic compounds lost due to chemical or physical reactions (including, for example, those that are destroyed, e.g. by incineration or other waste-gas or waste-water treatments, or captured, e.g. by adsorption, as long as they are not counted under O6, O7 or O8).

06. Organic solvents contained in collected waste.

07. Organic solvents, or organic solvents contained in preparations, that are sold or are intended to be sold as a commercially valuable product.

08. Organic solvents contained in preparations recovered for reuse but not as input into the process, as long as they are not counted under O7.

09. Organic solvents released in other ways.

Guidance on use of the solvent management plan for verification of compliance

4. The use of the solvent management plan will be determined by the particular requirement which is to be verified, as follows:

(a) Verification of compliance with the reduction option mentioned in paragraph 6 (a) of the annex, with a total limit value expressed in solvent emissions per unit product, or as otherwise stated in the annex.

(i) For all activities using the reduction option mentioned in paragraph 6 (a) of the annex, the solvent management plan should be
put into effect annually to determine consumption. Consumption can be calculated by means of the following equation:

C = I1 – O8

A parallel exercise should also be undertaken to determine solids used in coating in order to derive the annual reference emission and the target emission each year;

(ii) For assessing compliance with a total limit value expressed in solvent emissions per unit product or as otherwise stated in the annex, the solvent management plan should be put into effect annually to determine emission of NMVOCs. Emission of NMVOCs can be calculated by means of the following equation:

E = F + O1

Where F is the fugitive emission of NMVOC as defined in subparagraph (b) (i) below. The emission figure should be divided by the relevant product parameter;

(b) Determination of fugitive emission of NMVOCs for comparison with fugitive emission values in the annex:

(i) Methodology: The fugitive emission of NMVOC can be calculated by means of the following equation:

F = I1 – O1 – O5 – O6 – O7 – O8

F = O2 + O3 + O4 + O9

This quantity can be determined by direct measurement of the quantities. Alternatively, an equivalent calculation can be made by other means, for instance by using the capture efficiency of the process.

The fugitive emission value is expressed as a proportion of the input, which can be calculated by means of the following equation:

I = I1 + I2

(ii) Frequency: Fugitive emission of NMVOCs can be determined by a short but comprehensive set of measurements. This need not to be done again until the equipment is modified.

Appendix II

REDUCTION SCHEME

Principles

1. The purpose of the reduction scheme is to allow the operator the possibility to achieve by other means emission reductions equivalent to those achieved if the limit values were to be applied. To that end the operator may use any reduction scheme specially designed for his installation, provided that in the end an equivalent emission reduction is achieved. Parties shall report on progress in achieving the same emission reduction, including experience with the application of the reduction scheme.

Practice

2. If applying coatings, varnishes, adhesives or inks, the following scheme can be used. Where it is inappropriate, the competent authority may allow an operator to apply any alternative exemption scheme which it is satisfied fulfils the principles outlined here. The design of the scheme takes into account the following facts:

(a) Where substitutes containing little or no solvent are still under development, a time extension must be given to the operator to implement his emission reduction plans;

(b) The reference point for emission reductions should correspond as closely as possible to the emissions that would have resulted had no reduction action been taken.

3. The following scheme shall operate for installations for which a constant solid content of product can be assumed and used to define the reference point for emission reductions:

(a) The operator shall forward an emission reduction plan which includes in particular decreases in the average solvent content of the total input and/or increased efficiency in the use of solids to achieve a reduction of the total emissions from the installation to a given percentage of annual reference emissions, termed the target emission. This must be done in the following time frame:

Time period		Maximum allowed total annual emissions
New installations	Existing installations	Maximum allowed total annual emissions
By 31.10.2001	By 31.10.2005	Target emission x 1.5
By 31.10.2004	By 31.10.2007	Target emission

(b) The annual reference emission is calculated as follows:

(i) The total mass of solids in the quantity of coating and/or ink, varnish or adhesive consumed in a year is determined. Solids are all materials in coatings, inks, varnishes and adhesives that become solid once the water or the volatile organic compounds are evaporated;

(ii) The annual reference emissions are calculated by multiplying the mass determined as in subparagraph (i) by the appropriate factor listed in the table below. The competent authorities may adjust these factors for individual installations to reflect documented increased efficiency in the use of solids.

Activity	Multiplication factor for use in subparagraph (b) (ii)
Rotogravure printing; flexography printing; laminating as part of a printing activity; printing; varnishing as part of a printing activity; wood coating; coating of textiles, fabric, film or paper; adhesive coating	4
Coil coating; vehicle refinishing	3
Food contact coating; aerospace coating	2.33
Other coatings and rotary screen printing	1.5

(iii) The target emission is equal to the annual reference emission multiplied by a percentage equal to:

– (The fugitive emission value + 15), for installations in the following sectors:

– Vehicle coating (solvent consumption < 15 Mg/year) and vehicle refinishing;

– Metal, plastic, textile, fabric, film and paper coating (solvent consumption between 5 and 15 Mg/year);

– Coating of wooden surfaces (solvent consumption between 15 and 25 Mg/year).

– (The fugitive emission value + 5) for all other installations;

(iv) Compliance is achieved if the actual solvent emission determined from the solvent management plan is less than or equal to the target emission.

Where a Party determines that banning petrol with a sulphur content which does not comply with the specifications for sulphur content in table 10, but does comply with table 8, would raise severe difficulties for its industries in making the necessary changes in their manufacturing facilities by 1 January 2005, it may extend the time period of marketing within its territory until 1 January 2007 at the latest. In such a case the Party shall specify, in a declaration to be deposited together with its instrument of ratification, acceptance, approval or accession, that it intends to extend the time period and present written information on the reason for this to the Executive Body.

Annex IX

MEASURES FOR THE CONTROL OF EMISSIONS OF AMMONIA FROM AGRICULTURAL

SOURCES

1. The Parties that are subject to obligations in article 3, paragraph 8 (a), shall take the measures set out in this annex.

2. Each Party shall take due account of the need to reduce losses from the whole nitrogen cycle.

A. Advisory code of good agricultural practice

3. Within one year from the date of entry into force of the present Protocol for it, a Party shall establish, publish and disseminate an advisory code of good agricultural practice to control ammonia emissions. The code shall take into account the specific conditions within the territory of the Party and shall include provisions on:

– Nitrogen management, taking account of the whole nitrogen cycle;

– Livestock feeding strategies;

– Low-emission manure spreading techniques;

– Low-emission manure storage systems;

– Low-emission animal housing systems; and

– Possibilities for limiting ammonia emissions from the use of mineral fertilizers.

Parties should give a title to the code with a view to avoiding confusion with other codes of guidance.

B. Urea and ammonium carbonate fertilizers

4. Within one year from the date of entry into force of the present Protocol for it, a Party shall take such steps as are feasible to limit ammonia emissions from the use of solid fertilizers based on urea.

5. Within one year from the date of entry into force of the present Protocol for it, a Party shall prohibit the use of ammonium carbonate fertilizers.

C. Manure application

6. Each Party shall ensure that low-emission slurry application techniques (as listed in guidance document V adopted by the Executive Body at its seventeenth session (decision 1999/1) and any amendments thereto) that have been shown to reduce emissions by at least 30% compared to the reference specified in that guidance document are used as far as the Party in question considers them applicable, taking account of local soil and geomorphological conditions, slurry type and farm structure. The timescales for the application of these measures shall be: 31 December 2009 for Parties with economies in transition and 31 December 2007 for other Parties. 1/

7. Within one year from the date of entry into force of the present Protocol for it, a Party shall ensure that solid manure applied to land to be ploughed shall be incorporated within at least 24 hours of spreading as far as it considers this measure applicable, taking account of local soil and geomorphological conditions and farm structure.

D. Manure storage

8. Within one year from the date of entry into force of the present Protocol for it, a Party shall use for new slurry stores on large pig and poultry farms of 2,000 fattening pigs or 750 sows or 40,000 poultry, low-emission storage systems or techniques that have been shown to reduce emissions by 40% or more compared to the reference (as listed in the guidance document referred to in paragraph 6), or other systems or techniques with a demonstrably equivalent efficiency. 2/

9. For existing slurry stores on large pig and poultry farms
of 2,000 fattening pigs or 750 sows or 40,000 poultry, a Party shall achieve emission reductions of 40% insofar as the Party considers the necessary techniques to be technically and economically feasible. 2/ The timescales for the application of these measures shall be: 31 December 2009 for Parties with economies in transition and 31 December 2007 for all other Parties. 1/

E. Animal housing

10. Within one year from the date of entry into force of the present Protocol for it, a Party shall use, for new animal housing on large pig and poultry farms of 2,000 fattening pigs or 750 sows or 40,000 poultry, housing systems which have been shown to reduce emissions by 20% or more compared to the reference (as listed in the guidance document referred to in paragraph 6), or other systems or techniques with a demonstrably equivalent efficiency. 2/ Applicability may be limited for animal welfare reasons, for instance in straw-based systems for pigs and aviary and free-range systems for poultry.

Notes

1/ For the purpose of the present annex, “a country with an economy in transition” means a Party that has made with its instrument of ratification, acceptance, approval or accession a declaration that it wishes to be treated as a country with an economy in transition for the purposes of paragraphs 6 and/or 9 of this annex.

2/ Where a Party judges that other systems or techniques with a demonstrably equivalent efficiency can be used for manure storage and animal housing in order to comply with paragraphs 8 and 10, or where a Party judges the reduction of emissions from manure storage required under paragraph 9 not to be technically or economically feasible, documentation to this effect shall be reported in accordance with article 7, paragraph 1 (a).
