A blank total means no record disclosed the figure; the count without one says how many.
Summed only where a record disclosed the figure; a record with no figure adds nothing and is counted as not disclosed. Water is summed per day and per year separately, as the sources stated it, and never converted. A tax claim given as a range is summed at both ends.
| Use | Records | Power | Water | Jobs | Tax each year |
|---|---|---|---|---|---|
| No stated use | 4 | 4 MW |
A blank cell means no record with that use disclosed the figure.
A record that lists several uses counts once under each. Each cell is the sum over the records with that use, disclosed rows only.
No source on file states what any of the 4 tracked facilities in Montgomery County are for.
