Thanks, Eric. Should have been more careful.

My coal consumption estimate was wrong for more reason than overestimating HHV and so water consumption was also. Say 30,000,000 gallons per day, not 169,000,000, and 55,000 households not 375,000. A 10" pipe not a 24".

I worked in the coal business before moving over into petroleum in 87. My family had a small coal mine, wash plant and marketing company. We bought coal from other small mines and washed and sold the coal. A Great Lakes coal sales company bought us out and I was introduced to all kinds of coal blending, burning equipment, specs, etc. Our specialty was 12,800-13,500 East KY/West VA coal off the Big Sandy. We railed this to ports in Ohio then put it on steamships for our dock network.
In 86, our company was bought by a major oil company and I got the job of selling all the resids a year later.

Regardless, if costs more to bring into compliance than it's worth, it gets sold for scrap. The enviros win another one.
