Notice of a Public Hearing for a Safe Use Determination for Diisononyl Phthalate (DINP) in Vinyl Flooring Products

The California Environmental Protection Agency’s Office of Environmental Health Hazard Assessment (OEHHA) is the lead agency for the implementation of the Safe Drinking Water and Toxic Enforcement Act of 1986 (commonly known as Proposition 65, codified at Health and Safety Code section 25249.5 et seq.). OEHHA has received a request from the Resilient Floor Covering Institute (RFCI) that OEHHA grant a Safe Use Determination (SUD) for the use of diisononyl phthalate (DINP) in vinyl flooring products. RFCI is an industry trade association representing resilient flooring manufacturers, and suppliers of raw materials, additives and sundry flooring products, for the North American market. The request is made by RFCI pursuant to Title 27 of the California Code of Regulations, section 25204(b)(3).

RFCI requests OEHHA to determine that exposures to DINP in vinyl flooring products do not present significant cancer risks under Proposition 65, and do not require a warning. The basis for the request is that RFCI estimates the potential lifetime average daily exposures from inhalation, ingestion, and dermal absorption to installers and consumers would be below the level posing no significant risk, as defined in section 25703. This SUD request is limited to exposures to DINP only. Exposure to other listed substances, if any, that may be present in the vinyl flooring products will not be reviewed by OEHHA in the context of this request.

In accordance with the process set forth in section 25204(f)1, a public hearing has been scheduled for Wednesday, February 25, 2015, in the Sierra Hearing Room on the 2nd Floor of the California Environmental Protection Agency Headquarters, 1001 I Street, Sacramento, CA 95814, as an opportunity for public comment on this request for a safe use determination. The hearing will be held between 10:00 a.m. and 1:00 p.m.

The public may also submit written comments on this request. In order to be considered, OEHHA must receive comments by 5:00 p.m. on Wednesday, February 25, 2015.
