EPA Proposes New Rule To Crack Down on Deadly Air Pollution (cnn.com) 59

For the first time since 2012, the US Environmental Protection Agency is proposing an update to the federal air quality standard for fine soot -- a long-awaited step to reduce deadly air pollution. From a report: The current standard, which has been in place for more than a decade, limits the average annual amount of fine particle pollution to 12 micrograms per cubic meter of air. The EPA is proposing reducing that limit to 9 to 10 micrograms, though it will be taking public comment on a range as low as 8 and as high as 11 migrograms per cubic meter. The final standard will be a single digit somewhere in that range.

Fine particulate matter -- called PM2.5 -- pollutes outdoor air by the burning of fossil fuels like gasoline, diesel and oil, as well as wood. It is the tiniest pollutant yet among the most dangerous. When inhaled, it travels deep into lung tissue, where it can enter the bloodstream and can contribute to cardiovascular disease, asthma and other respiratory illnesses. Exposure to this pollution has also been linked to an increased risk of lung cancer in people who have never smoked. Scientists recently found a possible mechanism for that increased risk -- some air pollution particles may promote mutations in cells in the airways.

      There is a problem, yes. Reducing air pollution a lot will likely give us another 0.5C global warming and that is not accounted for in all the fantasy goals of stopping things at 1.5C. On the other hand, keeping pollution up means people get sich and die from it and cause a lot of medical cost and effort to society which would be needed in other places. Also fossiles continue to need to be burned to keep dust up, which will contribute more than that 0.5C estimate.

        It's packed because Republicans vetoed any Dem nominee for spurious reasons, then forced through their own candidates on the basis of lies and deceit.

        So because China and the developing world are not taking the same steps or not as fast we should just sya fuck it and not try and advance technology and our own industries at all? Is this what American exceptinalism has become, always aim for right above the lowest common denominator?

        To me at least while America can use it's influence as the global hegemon where it's possible we have to accept we can't force every nation to do what we want, especially developing ones where frankly it's a bit unfair to malign them for doing the same things we did decades ago to advance.

        I want the US to be the leader, to set the example and to show whats possible because we have the means, the drive and the money to do it. We should be electrifying, cleaning our air and setting higher standards for ourselves because we want to show we should remain the leader. Thats being exceptional, sacrificing what we know it the best in the long term for pure economic profit is just letting China jump ahead (and for all their coal plants they are also installing quite a bit of solar, nuclear and wind at the same time, not to mention their rail and mass transit expansion makes us look downright incompetent sometimes)

We have already dramatically reduced pollution through innovations such as the catalytic converter (which none of these little scooters have). It's great example of making a technology better (cleaner) without completely abandoning it (the internal combustion engine). It's the reason why pollution in places like Los Angeles is already much better than it was in the 1980's, even though the actual number of vehicles has

        Other countries not doing enough to reduce global warming does not absolve us from the responsibility of doing what we can to try to combat it ourselves. All you're basically doing is engaging in whataboutism. Nothing that you've said means the United States shouldnt take action to reduce its own emissions.

        Also, I'm sure you think you're "owning the Libs" with the "racism" thing but it just makes you look like a nutter.

            Destroying our economy in the US will only empower China, resulting in a net increase in pollution.

            A small and incremental decrease to large particle emissions is not "destroying our economy" any more than the last decrease in 2012 when it was dropped to 12 micrograms was.

            Your response, however, shows that you are part of the problem, not part of the solution. If we really cared about reducing pollution, we would be building new nuclear power-plants...

            "Part of the problem", give me a fucking break. "Part of the problem" is claiming minor emission changes are going to destroy our economy. "Part of the problem" is citing foreign countries misbehaviour as a reason to not take responsibility for our own contribution to the problem.

          Yeah there's a disconnect alright, but it is nuanced.

          It's true that localized particulate emissions are of less consequence to the wider population. As a farmer, though, they are of consequence to me. Diesel smoke gives me quite a headache. I'm glad the newer engines are so much cleaner in that regard. I can open the shop door and start up a tier 4 engine in my shop and run it for quite a while and never smell diesel smoke.

          NOx emissions, on the other hand, travel much farther and are of general concern, hence catalytic systems for diesels (which fail all the time). That said, the amount of NOx emitted by ag diesel engines is pretty much negligible on a national scale and an exemption should have been carved out. If only there were a way to help all the politicians and people in general feel the pain inflicted by all these regulations. Since it's for the greater good, the greater population should help directly feel the pain and bear the cost. After all it feeds them and brings them their amazon packages and makes an enjoyable lifestyle possible.

          Personally I don't mind putting DEF in a machine, but what bugs me is that often times the system fails because of something simple like a failed diaphram pump inside the dosing controller. But I can't open that up and fix it---there are no parts available because it's not user-serviceable. And this is because of all the EPA regs, they are paranoid of me opening this box, lest I might defeat it. Faced with a $4000 bill every year or two to replace dosing modules, the delete looks mighty attractive.

          Laws should be mandating very long warranties on these systems.

          It bugs me generally how politicians and the wider population think that the answer is always just to legislate solutions and expect someone else will figure out. They have no interest in finding or funding solutions themselves.

  • And good riddance, really. They can continue to exist in the back country where EVs won't suit, but fossil fuel vehicles of all kinds [slashdot.org] are a major source of PM2.5. One way to help mitigate this without any exotic technology for the remaining ICEVs is to use gaseous fuels and bio-based crankcase lube. CNG, LNG, and LPG are all immediately viable, LPG probably being the smartest of the batch. The bio-based oil doesn't last quite as long, but gaseous fuels also don't pollute it as much, so it evens out. Since a

This is exactly how you guarantee premature bearing failure, so congratulations you reduced some operational emissions while drastically increasing both constant failure rates and wear out failures.

          It wasn't clear that you were using crankcase lube as a euphemism. As to actual engine oils, having a lubricant congeal at even mildly cold temperatures is an outright disqualifier, even for use in desert climate that can still get cold at night.

    Air the fact someone nearby is polluting, then tie local polluters to the likely causes. It does little good to enforce a limit if you can't find everyone contributing to it. And air pollution is "hard" to track. Or harder than lots of other things.

    I guess that's another tick mark for global surveillance (of one sort or another).

    • No amount of PM2.5 is good for you, period. A lot of PM2.5 is carcinogenic because any persistent irritant can cause cancer, a lot of the particulates are very stable, and they are smaller than cilia so they are hard to expel from the lungs. Reducing the allowable limits to as close as you can practically get to zero is a positive step. They probably have specific areas in mind when they set these numbers.

  • Diesel particulates cause lung cancer and heart attacks, yet EPA has done nothing about it. Lumping them in with other fine particulates diminishes Diesel particulates' impact on human lives. For instance, particulates that are water soluble aren't much of a problem as your lungs can expel them. It's about time for EPA to quit pandering to railroads and other users of Diesel engines and adopt meaningful controls on them.
