OEHHA has extended the public comment period for the inhalation unit risk (IUR) factors for cobalt and cobalt compounds to May 7, 2019.  OEHHA released the draft document Cobalt and Cobalt Compounds Cancer IUR Factors for public review on March 8, 2019.  The public period was scheduled to close on April 22, 2019.  However, OEHHA received a request from ToxStrategies, Inc., to extend the period and it has done so.

OEHHA is required to develop guidelines for conducting risk assessment under the AB 2588 Air Toxics Hot Spots Program.  The cobalt and cobalt compounds cancer IUR factors were developed using the most recent Air Toxics Hot Spots Program Technical Support Document for Cancer Potency Factors finalized by OEHHA in 2009.
