Title: Significant New Use Rule for Chloranil
Abstract: Chloranil is used as a basic feedstock for certain dyes and pigments and in the production of rubber tires. Chloranil was one of the chemicals identified for testing in the Dioxin/Furan (D/F) test rule. Early testing results revealed that dioxin levels in Chloranil could vary by more than two orders of magnitude depending on the chemical manufacturing process involved. It appeared that the low dioxin manufacturing process could produce Chloranil with dioxin contamination levels below 20 ppb TEQ. Based on this information, EPA entered into a formal agreement with Chloranil importers (there was no domestic production of "high dioxin" Chloranil) to only import Chloranil made through the "low dioxin" process. As a follow up to this agreement, a Chloranil Significant New Use Rule (SNUR) was proposed in 1993. Under the provisions of the draft SNUR any Chloranil imported or domestically produced with dioxin contamination levels greater than 20 ppb TEQ would be considered a new use and require reporting under section 5(a)(1)(A) of the Toxic Substances Control Act. In the SNUR proposal EPA stated that it would not promulgate a final rule until it had all of the D/F test rule data. EPA accepted the final test rule data in June of 2001. The test rule requirements continue to apply to any new manufacturer or importer of Chloranil. No new importer or manufacturer has identified themselves, although EPA has received inquiries from time to time about the applicability of the test rule to new imports. OPPT therefore believes that all importation of Chloranil is still covered under the formal agreements and that there is no current import or domestic manufacture of high dioxin Chloranil. Because a significant time has passed since proposal, OPPT reopened the comment period in 2007.
