Yes. Most landfills can't take haz mat. Its gotta be transferred to a landfill that is certified for that specific product. Most larger landfills will take some form of special wastes but it's usually only a handful of special wastes. If it aint just household trash, its gotta have a special certification , classification and 10 million rules to go with it, and each waste is a separate classification and requires a specific certification from DEQ, Its expensive. and gets expensive quick.
I remember when I worked for WM, there was some sort of special construction or demo project of some sort going on locally and the only landfill that could take it was in California I believe.
Its not unusual. As many certifications as the local WM landfill had, it was still limited to basic household waste and some special certifications. They couldn't even take white goods as they called them Refrigerators, washers, dryers etc. No tires, no batteries, etc. All of those things had to be taken to a special facility.

I know we have a a special day, twice a year, here locally where you can take old paint, batteries, fluids etc, and its loaded onto big trucks and shipped away.
Another landfill in a neighboring parish could only take things like wood & paper. They called it construction waste. So they designed their landfill more as a transfer station. a pit with an 18 wheeler in it and all other waste would be loaded in it... yes, even regular household waste and brought to our landfill 40- 50 miles away.
There used to be 4 or 5 transfer trucks a day come from central Louisiana to our north Louisiana facility on a daily basis.... about 100 miles.
We used to ship some stuff to a facility in Arizona for a while at one time.
So, some haz mat has to go to various landfills all over the US.... Some overseas I think.
