Same here. Dig it out and backfill or crush it and backfill. Crushing the top in was a LOT cheaper. I don't know why they even mention the other.

You can do that if you aren't going to ever build over the septing tank. If you're on a smaller lot, it's much better to compact to 99%. If you're on a farm, it does not matter.
