This is kind of hilarious, the reason ended up being them putting the notices to close to each other temporally:

Several lawsuits followed, with the one that appears to have eventually collapsed the massive project hinging on an ironically small detail. The landmark mega project — roughly double New York’s Central Park’s size with city-sized power needs — collapsed in a domino effect after Virginia courts voided the county’s initial rezoning approval due to improper public notices. The newspaper notices publicizing the hearing at which the project was approved weren’t separated by at least 6 days, as mandated by state and local codes at that time, thereby invalidating the hearing and the resulting approval.
