Toxics Release Inventory. List of Toxic Chemicals within Warfarin Category

摘要

EPCRA section 313 requires threshold determinations for chemical categories to bebased on the total of all chemicals in the category manufactured, processed, or otherwise used. The warfarin salts category is subject to the one percent de minimis concentration. Thus, mixtures that contain members of these categories in excess of the de minimis should be factored into threshold and release determinations. EPA is providing a list of CAS numbers and chemical names to aid the regulated community in determining whether they need to report the Warfarin category. However, this list is not exhaustive. If a facility is manufacturing, processing, or using a chemical which has a warfarin salt component, they must report to TRI, even if this chemical does not appear on the list.
