This article reminded me of a story a few years back where a plant decided to recycle the benzine solvent they were using rather than pay fines or pay for the toxic disposal. The EPA officials decided they were still going to fine them for the amount they cycled through the plant.
I got a sneaky suspicion that the recyclers and toxic disposal companies are in bed with the EPA.
I used to work at Kennedy Space Center, and rainwater that collected in sumps there was categorized as "hazardous waste", because it had come in contact with galvanized gratings and the zinc content was "too high".
Same with various nitrogen compounds in water solution. Most places call that "fertilizer", but at KSC it was "hazardous waste".
It cost the American taxpayer $1.00 per gallon to haul off hundreds of thousands of gallons of rainwater every year.
