>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.
