Coal Combustion Products and REACH (status 31.01.2011)  

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 can not be produced and placed on the market.
Exemption: For CCPs which have been pre-registered by 1. December 2008 the deadline for registration is extended by 1. December 2010 (production volume > 1000 tonnes), by 30. June 2013 (production volume > 100 tonnes) or 30 June 2018 (production volume > 1 tonne). 

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.

The producers/importers of substances with the same EC-numbers form so-called pre-SIEFs (Substance Information Exchange Forum). Out of these pre-registered parties a "facilitator" organises the pre-SIEF communication and cares for open questions within the pre-SIEF.

Table: Situation pre-SIEFS for registration of Coal Combustion Products (CCPs) (status 31.01.2011)

The pre-registered parties agreed about the sameness of substances, defined Substance Identity Profiles (SIP) and formed Substance Information Exchange Fora (SIEF) for the preparation of joint registration dossiers with chemical, physical, toxicological and ecotoxicological data. For the registration of one substance only one registration dossier with the specific registration data can be filed. The SIEF members agreed for a so-called "Lead Registrant" who submitted the substance specific joint registration dossier to the ECHA.

Consortia were formed for calcium sulfate, ashes (fly ash, bottom ash and boiler slag), for FBC-ash and for SDA product.

By 1st December 2010, the following substances were registered
-    Calcium sulfate (natural and FGD gypsum)
-    SDA-Product*
-    Ashes from wet and dry bottom boilers (fly ash, bottom ash, boiler slag)*
-    Ashes from fluidized bed combustion boilers*
-    Cenospheres

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

Legal entities being members of the joint registration referred to the joint registration dossier by a token number provided by the lead registrant.
 
Pre-registered parties which will register at a later stage and are not members of a consortium can contact the lead registrant or contact partners listed below and ask for a letter of access (LoA) to the joint registration dossier.

Parties not being pre-registered can also ask for a LoA. However, they have to send an inquiry to ECHA to get a company specific number for registration and contact data to the lead company which has registered the same substance.

Information regarding sameness of substances for registration of CCPs and details of consortia are given below.

Calcium sulfate (the registration covers FGD- and natural gypsum)

Note: For using rights for studies from Korea a second LoA has to be ordered.

SDA-Product (the registration covers "clean" SDA product (< 10 % ash content))

Ashes from wet and dry bottom boilers:

Ash-REACH-Consortium together with the By-Products Consortium and the
ASVEP-Consortium
Lead Registrant:     Evonik Steag GmbH

Ashes from fluidized bed combustion boilers (FBC-Ash)

Cenospheres

Mixed Ash Consortium was formed.
