VCVSHealth <br />Ms. Flondo <br />March 20, 2019 <br />Page 3 <br />is important that the residues be managed in a more controlled manner—such as in <br />municipal solid waste landfills—rather than poured down the drain. <br />3. EPA carefully assessed whether destruction of empty warfarin containers is warranted <br />and ultimately determined that destruction is not necessary. Although EPA's proposed <br />rule would have required destruction of empty containers, EPA ultimately did not finalize <br />the requirement to destroy the empty containers prior to disposal, given the potential for <br />worker safety concerns if required to crush or shred the containers. <br />We emphasize the above points from the Pharm Rule because EPA carefully considered <br />whether residue and empty containers should be managed as hazardous (or acute hazardous) <br />waste. Based on (i) data (such as the studies that EPA reviewed) supporting the conclusion that <br />very little residue remains in containers after the pharmaceuticals are dispensed, and (ii) for <br />policy reasons (such as avoiding sewering of residues after triple -rinsing), EPA determined that <br />it is not appropriate to manage the residues or containers as hazardous (or acute) hazardous <br />waste. <br />California. We are aware that prior to EPA's publication of the Pharm Rule, DTSC <br />issued a December 24, 2015 interpretation rejecting EPAs November 4, 2011 memorandum <br />regarding empty containers. DTSC interpreted California's regulations as more stringent than <br />federal regulations and stated: "The distinction between the regulations is that the federal <br />regulation specifically addresses the `Residues of hazardous waste in empty containers' ... and <br />California's regulation addresses the `Contaminated Containers' as whole entities." <br />The DTSC letter quoted California Code of Regulations, title 22, section 66261.7(r): <br />Any container, or inner liner removed from a container, which previously <br />held a hazardous material, including but not limited to hazardous waste, and which <br />is not empty as defined in subsection [...](d) of this section, ... shall be manamed <br />as a hazardous waste in accordance with this division and Chapter 6.5 of Division <br />20 of the Health and Safety Code (commencing with Section 25100). <br />(Emphasis added). DTSC furt <br />her stated: <br />When DTSC observes a hazardous waste that is comprised of non -empty <br />containers having RCRA P -listed hazardous waste residues inside them, DTSC <br />considers the entire container and residue combination as "the hazardous waste" <br />that must be properly managed to protect human health and the environment. <br />Accordingly, generators must include the weight of the container and not just the <br />mass of container residue when computing the amount of acute hazardous waste <br />generated (i.e. handling each residue and its associated container as a whole entity <br />of hazardous waste).
