Agenda

Guidebook revision Maintenance and Improvement Plan

for Guidebook Report from Task Force on Reactive

Nitrogen

Guidebook revision

NMVOC emissions from Animal Husbandry and Manure Management (4B)

NMVOC emissions in 4B

No emission factor in the current Guidebook

New emission factor in revised Guidebook For some Parties, 4B would become the major

source Reasoned criticism at previous TFEIP meeting Re-assess the evidence underpining emission

factor

4B NMVOCs conclusions

Emission factor in revised Guidebook unreliable

Requires more detailed review

NMVOC – proposed action

Revert to position in current Guidebook No emission factor for 4B – leave placeholders

Include review in Maintenance Plan Timescale

Work ongoing in Europe and USA US-EPA plan to establish emission factors in

2011 Propose to undertake review in 2010

Funding 60 days

EFDB

Just Guidebook emission factors (linked to Guidebook)

Just Guidebook emission factors (unlinked)

Guidebook and national emission factors (unlinked)

Guidebook and submitted emission factors (unlinked)

Just Guidebook (linked)

Create additional work Database – Excel – Word Need to restructure database when amending

methodologies

Limited resources Would divert resources from Guidebook

maintenance and improvement

Not convinced of substantial (non-Guidebook) benefits

Other options

Just Guidebook emission factors (unlinked) OK

Guidebook and national emission factors (unlinked) OK – if IIRs available as documentation

Guidebook and submitted emission factors (unlinked) Quality control issues or resource issues

Revision process in the future

Rolling revision of chapters Depends on scientific/technological

developments All chapters should be revised regularly

Chapters recommended for endorsement

Nature 11B Forest fires B1109 Gas seeps

Natural sources

Natural Sources to be considered:

Sources Pollutants

Vegetation, esp. Forests NMVOC

Biomass burning and forest fires (new) NOx, PM, CO, CO2, CH4, OC, EC, VOC

NO from soils NO

Pollen (New) PM

Wild animals CH4, NH3

Anoxic soil processes (wetlands) CH4

Natural seepage of gas storage CH4, NMVOC

Wind blown dust (incl. Saharan) (new) PM

Volcanoes SOx, NOx, PM, HF, HCl, CO2, HNO3

Lightning NOx

Sea, Coastal zones (New) PM, DMS

Specific items for the Maintenance Plan

Review of NMVOC emissions in 4B Review of ammonia emission from

fertilisers VOC emissions from vegetation Methodology for ammonia emissions

from biogas facilities Ammonia emission from crops

Priorities and resources

Review of NMVOC emissions in 4B Priority 1 60 days

Review of ammonia emission from fertilisers Priority 2 25 days

Priorities and resources

VOC emissions from vegetation Priority 2 0 days

Methodology for ammonia emissions from biogas facilities Priority 3 2-10 days

Ammonia emission from crops Priority 3

Any other business

Potential versus net emissions PM and NMVOCs Make clear in Guidebook Who should calculate net emissions?
