Those rules were promulgated long ago, and U.S. <br /> EPA was very clear,based on its own and other studies that there was no basis for managing <br /> empty warfarin containers as hazardous waste or counting their weight towards generator status. <br /> U.S. EPA's rule re "empty containers" states at 40 CFR 266.507(a): <br /> Stock, dispensing and unit-dose containers. A stock bottle, dispensing <br /> bottle, vial, or ampule (not to exceed 1 liter or 10,000 pills); or a unit-dose <br /> container(e.g., a unit-dose packet, cup,wrapper, blister pack, or delivery <br /> device) is considered empty and the residues are not regulated as <br /> hazardous waste provided the pharmaceuticals have been removed from <br /> the stock bottle, dispensing bottle, vial, ampule, or the unit-dose container <br /> using the practices commonly employed to remove materials from that <br /> type of container. (italics added). <br /> EPA's response to a comment from the rulemaking process also highlights its position: <br /> One commenter asked us to add an explicit reference to acute/P-listed <br /> hazardous waste in this section of the regulations. We believe this is <br /> unnecessary since § 261.7(c) indicates that containers of hazardous waste <br /> pharmaceuticals (which includes acute and non-acute hazardous waste <br /> pharmaceuticals) are subject to § 266.507 in lieu of§ 261.7 for <br /> determining when they are empty. Nevertheless, we agree with the <br /> commenter that all of the new empty container provisions in § 266.507 <br /> apply to containers that held either non-acute or acute hazardous waste <br /> pharmaceuticals. Under the new subpart P provisions, for containers that <br /> once held non-acute waste pharmaceuticals to be considered empty, it will <br /> not be necessary to measure the remaining contents, and for containers <br /> that once held acute hazardous waste pharmaceuticals, it will not be <br /> necessary to triple-rinse the containers or demonstrate an equivalent <br /> removal method. (emphasis added). <br /> In promulgating this rule, U.S. EPA conducted its own study as well as a review <br /> of the testing submitted by at least 3 other stakeholders to arrive at its conclusion that empty <br /> warfarin stock bottles are exempt from handling as hazardous waste. If the residue is insufficient <br /> to count as hazardous waste, the bottles themselves should not be counted as hazardous waste. <br /> See https://nepis.epa.gov/Adobe/PDF/P100NG6J.pdf <br /> 514079.1 <br /> A Professional Law Corporation <br />
