About how much power in the AM band does 24,000 uV/M at 30 meters equate to?

An EIRP of ~ 8.6 mW will generate 24 mV/m over a 30 m path length.
If the question relates to a Part 15 AM setup where the radiation efficiency of the antenna system is very low, the power applied to the antenna would be much greater than that in order for it to radiate 8.6 mW.
As an example, a good Part 15 AM setup using a ground-mounted 3-m vertical on 1700 kHz has a peak antenna system gain of about -20 dBi. So the power needed from the transmitter at the loading coil feedpoint would be about 100 * 8.6 mW = 860 mW.
