Short description - Quarrying & mining of Minerals other than Coal

NFR-Code Name of Category Method AD EF Key Category 1
2.A.5.a Quarrying & Mining - Other Than Coal T1 NS D L & T: TSP, PM10 | L: PM2.5

The mining process emits relevant amounts of particles. Quarrying and mining of minerals other than coal is subsumed, in particular mining of limestone, hard rock and building sands. Information about the current relevance is shown in 2.A Mineral Industry.

Method

With the use of the 2019 GB method [1], a Tier 2 method is available that can reflect different national conditions.

Since the GB tool in principle calculates emissions for exactly one year [2], files must be available for exactly those years in which input data are available. Intermediate years are interpolated in case of data gaps.

With the help of the GB tools, IEFs are reported on an annual basis, which are used for the inventory method AR x EF. Thus the activity data are presented transparently and can be discussed with data suppliers. The emission factors can be modified if further information on the parameters of the GB-tool is available.

Trend discussion

Trends in emissions follow the shrinking mining activities.

Recalculations

Recalculations were necessary due to revised AD and EF. Both the filled up AD and the moduled EF over time have resulted in higher emissions.

Planned improvements

At the moment, no improvements are planned.


Short description - Salt Production

Salt production is a sub-category of the mining activities in respect of the country specific approach used. Currently, a Tier 1 method is used: information on production of salts are multiplied with emission factors for TSP and PM.

Method
Activity data
The data from national statistics includes production of potash and rock salt. Potash salt is dominating, nevertheless gaps of statistics are filled and emissions are modelled as potash salt only.
Emission factors
The emission factors are based on analogy to bulk product handling by an expert judgements from UBA:

Table 2: Overview of applied emission factors, in kg/t salt
pollutant EF value EF trend
TSP 0.031 constant
PM10 0.016 constant
PM2.5 0.003 constant

Recalculations

With activity data and emission factors remaining unrevised, no recalculations have been carried out compared to last year's submission.

Planned improvements

At the moment, no category-specific improvements are planned.
