Reply to comment by EthanSayfo in Mayor Scott says contractor can’t discharge treated waste from Ohio train crash in city wastewater system by Cody_in_Baltimore

  1. it wasn't a DPW managed facility that exploded, it was caused by Synagro's centrifuge machines.

  2. Norfolk Southern isn't sending this to Back River, they're sending it to Clean Harbors. Back River would have fuckall to do with this treatment, the waste water back River receives would be treated like any other sewage.

Maybe if you have some evidence that Clean Harbors isn't meeting EPA guidelines before discharging to Back River you might have an argument, but it sounds like you have no idea what's actually happening.

I don’t trust Back River to make a proper assessment of what they get back from Clean Harbors before taking the water, and either putting it into the system properly, or improperly as the case may be.

So I take it that your opinion is that Clean Harbors should not be operating here at all? Or is there something specific about this waste that you're concerned about?

Edit: Lots of downvotes here, so for those of you who believe that Clean Harbors won't properly treat this waste, our politicians included it seems, why should they be allowed operate at all? What other harmful substances are they discharging to Back River?

I mean from one of the articles (I dont remember which one) they said they will treat the waste water to get it down to EPA acceptable levels of vinyl chloride (4 ppm) and PFOS/PFAS (4 ppt) and then discharge it into the sewers, which might technically be 'safe' for humans but I can't imagine would be good for our already struggling Harbor and Bay. Not to mention the risk (no matter how small) of something going wrong (like, oh, say, the same thing that caused the disaster in the first place in ohio) and having another ecological disaster here. There's just no need to contaminate other communities with this stuff; its already in ohio so just treat it there.

That's literally what they do all the time, that's their entire business.

So if you think it's a problem now that you've read a headline about it, should we be shutting them down completely?

If you read my comment my concern isnt that the company isnt capable of treating the waste its that the 'acceptable levels' of toxins in the effluent are not acceptable to me. We don't have any detectable vinyl chloride in the bay or harbor right now, why should we accept that 4ppm will make it in? It may be safe for humans technically, but do you really think that won't have any ecological effect?

How can you claim that? We've shown it multiple times, in multiple areas of the Bay, over the last 30 years:

Frog Mortar Creek, near Martin State Airport (2014)

EPA found 19 OCPSF and 12 Petroleum Refining facilities as the worst offenders in the Chesapeake in 2004, Vinyl Chloride was a subcategory of note within OCPSFs

Chesapeake Watershed Chemical's of Concern (2000)

Indian Acres on the Sassafras in 1996

I saw a few other sources published by Williams and Mary in 1992, but the scans didn't have OCR and were tough to navigate.

>If you read my comment my concern isnt that the company isnt capable of treating the waste its that the 'acceptable levels' of toxins in the effluent are not acceptable to me.

Again, this facility specializes in this, it's within their purview, they've probably handled Vinyl Chloride or other Chlor-Alkalis before (and likely worse on a regular basis), you just haven't been paying attention because it hasn't made national news.

It's totally fine if you've now decided that this is a concern, but then why are we just stopping this single occasion? The industrial waste treatment plant should be completely closed, right?

I really have two responses to this, first, yes of course I can claim that, because a small handful of VC incidents over 30 years of course doesn't contradict my point that we don't currently have any VC in the harbor or bay. Anyway, second more in depth response:

Yes, there have been a few incidents where vinyl chloride has been detected in small areas in the watershed. These are brief points in time and not a consistent presence of VC. This is quite different I would think than dumping a huge amount of effluent that still has significant amounts of it into, effectively, the bay. And to be clear, one of your links doesn't show a vinyl chloride leak, it lists VC as a chemical of concern. Another shows that it was detected at just over 1 ppb in a very small area. The Frog Martin link says that was an area of concern because, in part, vinyl chloride was found in the area (at a concentration of 0.7 ppb). The sum of all of this is that the detection of virtually any vinyl chloride in any area in the Chesapeake watershed has been a Big Deal. So how is your conclusion that discharging effluent at 4 ppm into the sewers is totally cool?

EPA limits are for vinyl chloride 2ppb. The highest concentration in the waste that was meant for here was 62ppb (or 0.062ppm). So yeah, pretty sure they weren't going to discharge at 4ppm...

>This is quite different I would think than dumping a huge amount of effluent that still has significant amounts of it into, effectively, the bay.

I think your sizes are off, 600,000 gallons is not a "huge amount" in this context.

My point is that you clearly have no idea what you're talking about. You've read a headline and are now outraged, and after this week you'll go about your life unaware of all the waste water that Clean Harbors treats and discharges to the sewer system.
