and initialisation of new facilities and problems related to the ammoniumthiosulfat
(ATS) plant has lead to increased emissions. In 2007 the
capacity of the ATS plant was increased followed by commissioning difficulties.

The applied methodology for uncertainty estimates refers to Pulles &
Aardenne (2004). The Danish uncertainty estimates are based on the
simple Tier 1 approach described in IPCC Good Practice Guidance
(IPCC, 2000).
The uncertainty estimates are based on the calculated emissions for the
base year and for the latest inventory year and on the uncertainty rates
for both activity data and emission factors. Data is aggregated for the
NFR category 1 B - Fugitive Emissions from Fuels. Base year refers to
2000 for particulate matter and to 1990 for the remaining components.
The uncertainty rates are based on the EMEP/EEA emission inventory
guidebook (2009), on uncertainty estimates from a minor number of
companies and on estimates and assumptions by NERI. The applied
uncertainty levels for activity data and emission factors are given in Table
3.58. The uncertainty rates vary between pollutants because the
emission sources vary as well.
