After several phone calls, many of which were not returned, I learned that one cannot do this. The oil is pumped out, “cleaned” and re-sold for industrial use.
If I knew how to get a grant, I would start a program to do something with the oil that people have left when they change heating systems.
There are thousands of people who cannot afford to put oil in their tanks in the winter, and LIHEAP cannot meet their needs completely.
I am outraged.
