I'm a bit confused here. These are recognized as being harmful. It's written all over the msds for these. What is the real change that is going to occur? I remember dealing with these substances in tiny quantities in the lab, and they were treated as carefully as cholorosifonic super acids. A lot of care goes into their disposal or recycle. One problem is making methods that can detect waste streams at under ppt levels, which is pretty difficult, but that's the best effort for dealing with these substances at the moment.

  What is the real change that is going to occur? Likely a bureaucratic formality that will force private entities to follow certain procedures.

  > A lot of care goes into their disposal or recycle. Are you aware of the usage of PFAS in textiles, food packaging, and waterproof-treated goods? I'm a little confused what you mean by care goes into their disposal. PFAS treatments on textiles for example are disposed of by pouring down a washing machine drain into municipal sewers and from there into natural waterways. Because of the "forever", small amounts add up, perpetually and over time could become not-small amounts.

    So what is the impact of this proposed EPA ruling on ordinary people disposing of ordinary household items like those you describe? Will we all need to have hazmat plants installed in our sewage lines? Will we no longer be able to wash our clothes in washing machines? Will we have to segregate all our trash and pay for our community to have a hazmat disposal truck come around along with the regular trash truck?

      No. No. And Maybe. Like most EPA regulations they will be enforced on the manufacturing/commercial side first. I'm not sure if you're being facetious or just disengenuously attacking regulatory agencies. If you're legitimately concerned, I apologize. On the bright side, you can rest easy.

        This is assuming the EPA still exists in a year, which I'm giving 50/50 odds.

        It'll still exist, however, it's powers will be reduced to nothing with the death of Chevron deference in June. This PFAs decision would be a prime example of something the EPA won't be able to regulate without a new congressional bill approving it.

I'm more generally concerned about whether the actual costs of such a regulation will be less than the actual benefits.
