European Pollutant Release and Transfer Register
Background
 European Pollutant Emission Register
familiar to cement and lime producers but
new to quarries
 2007 first year of monitoring for quarries

(E=AD*EF*AF)
E= emission to air to report
AD = activity data measures the activity of the facility
e.g.
– For PM10, quantity of product processed per year
– For other pollutant: annual fuel consumption or
annual working time
EF = emission factors as listed in approved reference
list
AD = attenuation factor as listed in approved reference
list e.g.
– Use of water spray during production decrease the
amount of PM10 emitted.
