Washington state advances 18 candidates for CHCC list

Washington state has issued preliminary draft rule text that would add 18 substances to its Chemicals of High Concern to Children (CHCC) list.

The state's ecology department says this marks the start of the final comment period before it submits a formal proposed rule early next year. It is the latest development in a stakeholder process, initiated in August, to amend the list of substances that require reporting under the state's Children's Safe Products Act (CSPA).

In the draft, the department has proposed adding:

  • the phthalates DIBP and DCHP;
  • the flame retardants DBDPE, TCP, TPP, TCPP, TBPH, TBB, TBPP, TDBPP, TNBP and EHDPP, IPTPP, SCCP, and V6;
  • the bisphenols BPF and BPS (alternatives to current CHCC-listed BPA); and
  • the perfluorinated compound PFOA, and its related substances.

It has also proposed delisting:

  • phthalic anhydride;
  • octamethylcyclotetrasiloxane (D4); and
  • molybdenum.

The department had earlier said it would exclude D4 from consideration for delisting. But in the newest draft, it says stakeholder comments provided new scientific studies sufficient to identify it for possible removal. The substance was originally included in the CHCC reporting list based on listing by the European Union as a possible endocrine disruptor.

Comments on the draft list amendments, evaluations of each chemical, and proposed changes to the regulatory text will be accepted until 13 January.

The Department of Ecology will host a webinar on 4 January to review the draft rule language and the updated CHCC list.

A previous version of this article incorrectly stated the comment deadline as 17 January.
