Apr 17, 2015

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 Chemical Fabrics & Film Association, Inc. (CFFA) that OEHHA grant a Safe Use Determination (SUD) for the use of diisononyl phthalate (DINP) in certain polyvinyl chloride (PVC) roofing products. CFFA is an international trade association representing manufacturers of polymer-based fabric and film products used in the building and construction, automotive, fashion and other industries. The request is made by CFFA pursuant to Title 27 of the California Code of Regulations, section 25204(b)(3).¹

This SUD request is limited to exposures to DINP in single-ply (SP) PVC roofing membrane products with a nominal thickness of between 1.016 to 2.438 millimeters (40 to 96 mils). Exposures to other listed substances, if any, that may result from such installation and use of these SP PVC roofing membrane products will not be reviewed by OEHHA in the context of this request.

In accordance with the process set forth in section 25204(f), a public hearing has been scheduled for Tuesday, May 19, 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 2:30 pm. to 5:00 p.m.
