Coal Combustion Products and REACH

On 1st June 2007, the REACH-Regulation (Registration, Evaluation, Authorisation and Restriction of Chemicals) entered into force. By this, also each producer or importer of coal combustion products (CCPs) has to register the marketed or imported substances at the European Chemicals Agency (ECHA) situated in Helsinki. Since 1 June 2008, CCPs which are not registered cannot be produced and placed on the market.

Due to special regulations for "phase-in" material like CCPs the producers/importers of CCPs have pre-registered FGD- gypsum, spray dry absorption product (SDA-product), fly ash ((FA) from hard coal/lignite), bottom ash (BA), boiler slag (BS) and fluidised bed combustion ash (FBC-ash) as well as cenospheres (CE) and ashes from biomass combustion (BMA) with the CAS- and EC-numbers of the specific substances. For production volumes of more than 1000 tonnes per year the pre-registration had to be done by 1. December 2008, the registration had to be completed by 1. December 2010.

The producers/importers of substances with the same EC-numbers formed so-called pre-SIEFs (Substance Information Exchange Forum). Out of these pre-registered parties a „facilitator“ organised the pre-SIEF communication and cared for open questions within the pre-SIEF. The pre-SIEF activities expired at the end of 2018.

Within the pre-SIEFs it was clarified which substances will be registered together. For this purpose, substance descriptions (Substance Identity Profiles - SIP) were defined, which do not necessarily correspond to the EC or CAS number. In case of deviations a new EC number was applied for. Substance identity is the prerequisite for the formation of a SIEF and for the preparation of a joint registration dossier with chemical, physical, toxicological and ecotoxicological key data. As a rule, only one registration dossier with the key data mentioned above has to be submitted for a substance.

The manufacturers/importers of a substance have designated a "Lead Registrant" who has submitted the substance-related registration dossier to the European Chemicals Agency. Afterwards the individual members of the joint registration submitted their specific registration dossiers. The joint dossier was referred to by a specific reference number (token).

By 1st December 2010 , the following substances were registered

  • Calcium sulfate (natural and FGD gypsum)
  • SDA-Product*
  • Ashes from wet an dry bottom boilers (fly ash, bottom ash, boiler slag)*
  • Cenospheres
  • Ashes from fluidized bed combustion boilers*
  • Asche from combustion of biomass

*for ashes and SDA product new EC numbers were used for registration.

New manufacturers/importers of already registered substances who are not members of a consortium can contact the lead registrant or the contact persons listed below and request a letter of access for the reference rights to the joint registration dossier.

In this case, registration is carried out via an enquiry to ECHA.

Information on substance sameness for CCP registration and details of consortia are also provided below.
