I realize this would be better programmed within the plc but was looking if it could be done through Ignition. I would like to start a pump if a tank level got to a certain level. Any suggestions on where this can be performed or script ideas would be very much appreciated.

One way to do this would be to add a tag change script to a tag that represented the tank level, and inside the script just check the current value and take action if it meets whatever criteria.

That being said, this is a bad idea.
