Proposition 65 Safe Use Determinations (SUDs)
A Safe Use Determination (SUD) is a written statement issued by OEHHA, which interprets and applies Proposition 65 and its implementing regulations to a specific set of facts in response to a request by a business or a trade group. Requests for SUDs seek OEHHA’s determination whether an exposure or discharge of a listed chemical resulting from specific business actions or the average use of a specific product is subject to the warning requirement or discharge prohibition. The SUD determines if the discharge or exposure is at or below the Safe Harbor number. Regulations setting out the requirements for requesting a SUD are found in Title 27, California Code of Regulations, section 25204.
