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: TSP | L & T: PM10

The mining process emits relevant amounts of particles. Quarrying and mining of minerals other than coal is subsumed, in particular mining of limestone and building sands.
Information about the key source relevance can be found in 2.A Mineral Industry.

Method

Activity data

Activity data are determined via summation of figures for various materials like limestone and building sands. Data based on information on production statistics are available from national statistics, therefore a common uncertainty of 3% is assumed.

Emission factors

The emission factors used are the UNECE-Defaults (EMEP/EEA emission inventory guidebook, Version 2013, chapter NFR 2.A.5.a, no changes in 2016 version).

Table 1: Overview of applied emission factors, in kg/t
pollutant Name of Category EF value EF trend
TSP mining other than coal 0.102 constant
PM10 mining other than coal 0.05 constant
PM2.5 mining other than coal 0.005 constant

Trend discussion

Trends in emissions follow the slightly shrinking mining activities.

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.


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:

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.
