Earlier this month, I offered testimony to the Environmental Safety Company (EPA) at a public listening to on the proposed rule on sterilization amenities that emit ethylene oxide (EtO), a cancer-causing gasoline. These amenities use EtO to sterilize medical gear, in addition to some dried spices and herbs. About half of all sterile medical gear within the US is sterilized with EtO. EtO can also be used to fabricate different chemical substances which can be used to make merchandise like antifreeze and plastics.
This proposal, which is almost a decade overdue, updates emissions requirements and necessities for “commercial sterilization” amenities. These new requirements depend on the findings of a 2016 risk assessment by EPA’s Built-in Danger Info System (IRIS) program, which decided that long-term publicity to EtO can enhance your threat of creating most cancers. The truth is, the 2016 IRIS threat evaluation discovered that EtO was as much as 60 occasions extra poisonous than beforehand understood.
These long-delayed rules will cut back public well being harms that communities close to these amenities have been uncovered to for many years. Many industrial sterilization amenities are in or close to residential areas, and in lots of instances, folks have no idea that this colorless, cancer-causing gasoline is being emitted of their group.
Stronger requirements are additionally a matter of environmental justice. In a report printed by UCS earlier this yr, we discovered that industrial sterilization amenities are disproportionately situated close to folks of coloration, folks with low revenue, and individuals who don’t converse English as a primary language (significantly Spanish talking communities). You possibly can see the place these amenities are situated and be taught extra concerning the impacted communities here.
The rule might go additional to guard public well being
The proposal will cowl not less than 86 industrial sterilization amenities throughout the US and Puerto Rico. Whereas the rule, if carried out, will cut back ethylene oxide emissions from sterilization amenities (by as much as 80 p.c, primarily based on EPA’s estimate), there are additionally main gaps. The proposal doesn’t think about cumulative impacts, doesn’t require amenities to put in fenceline displays—which individuals from impacted communities have requested for—and the rule doesn’t require off-site warehouses, the place newly sterilized gear is saved and continues to off-gas EtO, to manage or monitor emissions.
Communities have been left at nighttime about this invisible risk for too lengthy and EPA should swiftly act to undertake the strongest rules attainable to guard public well being. Whereas EtO undoubtedly ensures that medical units are protected, we should ask ourselves: can we sacrifice the well being and wellbeing of some for the sake of others? Along with advocating for the strongest controls practicable, we should additionally work towards phasing out using this cancer-causing gasoline as a lot as safely attainable.
Make your voice heard
At EPA’s public listening to on this proposal, I testified alongside environmental justice advocates, well being care staff, public well being practitioners, and affected group members who shared their experience, and for a lot of, their experiences residing and dealing close to these amenities. My colleague, Lisa, additionally testified, not simply as a member of UCS employees, but additionally as somebody who lives close to two excessive threat industrial sterilization amenities in Maryland.
Along with the listening to, EPA is accepting written comments on the rule by June 12. For tips about writing a public remark of your personal, see our comment guide on this rule. You may also sign up to hitch our remark writing workshops on Could 22 and 24.
Right here’s my full testimony:
Howdy, my title is Darya Minovi and I’m a senior analyst on the Union of Involved Scientists. Thanks for the chance to testify at this time.
This rule replace is overdue. An evaluation that UCS printed earlier this yr discovered that just about 14 million folks within the US and Puerto Rico reside inside 5 miles of a industrial sterilizer. There are additionally greater than 10,000 colleges and childcare facilities on this space. Whereas not everybody who lives inside 5 miles could also be uncovered to hazardous ranges of EtO, our evaluation sought to know the communities that could be impacted. We discovered that in 12 metro areas throughout the US, there are [quote] sterilizer hotspots, with two or extra sterilizers lower than 10 miles aside. We additionally discovered that the air toxics most cancers threat within the census tracts with sterilizers is 3 times better than the U.S. common.
Our evaluation additionally discovered that there was a better proportion of individuals of coloration, folks with low-income, and individuals who converse English as a second language within the communities inside 5 miles of sterilizers when in comparison with the U.S. common. Latine communities are significantly impacted. There are 5 sterilizers in U.S.-Mexico border communities and 7 in Puerto Rico. As EPA is aware of, 4 of those seven had EtO concentrations that exceeded EPA’s acceptable threat threshold. That is unacceptable.
Moreover, we noticed a big native degree disparity. Practically sixty p.c of economic sterilizers are in communities with a better proportion of individuals of coloration in comparison with county averages. The air toxics most cancers dangers have been additionally better in census tracts with a better proportion of individuals of coloration. In sum, folks of coloration look like disproportionately susceptible to publicity to EtO emissions, face elevated most cancers dangers from air toxics, and are in communities which can be extra prone to have a number of sterilizers.
With this in thoughts, we’re right here to echo our assist for the asks made by the individuals who reside, work, and play in these communities, a lot of whom didn’t know till lately, or nonetheless don’t know, {that a} facility emitting a cancer-causing gasoline is of their group.
We’re inspired by the proposals to broaden protection to on-site warehouses and different beforehand excluded processes, in addition to consideration of room air emissions. We additionally assist EPA’s resolution to proceed counting on the perfect out there science and utilizing the 2016 IRIS threat evaluation to set emissions requirements. Nevertheless, we strongly urge EPA to first require fenceline monitoring in any respect sterilizers. As said within the proposal, many communities have requested fenceline monitoring, and proof suggests these knowledge may help defend communities. For instance, the South Coast Air High quality Administration District in California lately required a Sterigenics facility to stop operations as a result of fenceline monitoring ranges exceeded the state’s motion degree. And that is at a facility that has put in everlasting whole enclosure. Fenceline monitoring saves lives.
Moreover, the rule ought to cowl off-site warehouses. Many firms transport sterilized medical gear to warehouses that aren’t topic to Clear Air Act rules. In impact, these warehouses act as secondary aeration chambers the place the sterilized gear continues to off-gas. Business sterilizers must be required to report the place these off-site warehouses are situated and the way a lot gear is saved in them. There also needs to be required monitoring to guard staff at these amenities and the group.
Lastly, we urge EPA to take care of an expedited timeline of at most 18 months for implementation of the rule, to explicitly think about cumulative impacts of EtO and different air toxics in enforcement of this rule, and to make sure that info concerning this rule and the dangers to communities is communicated in acceptable languages, particularly Spanish.
Whereas I completely acknowledge the significance of medical provide sterilization, I ask that you simply think about the merciless irony of harming a group’s well being for the well being of others. On this dialog concerning stronger emissions requirements, we should additionally think about phasing out using EtO the place it’s protected to take action. Safer alternate options exist. It isn’t essential to sterilize spices with EtO, and lots of medical units will be safely sterilized with substances like hydrogen peroxide. Thanks on your consideration.
