Farmers.gov has a page on the announcement of hemp insurance and other aspects of growing hemp.
They note the need to report acreage to FSA, including their hemp grower registration number. I searched on that and found this page for Virginia. Virginia, of course, requires its own series of acreage reports
IMO this is a classic instance of how bureaucratic silos develop. Something new comes up, and existing bureaucracies are assigned the job of implementing rules/laws. But since it's likely that the new responsibility doesn't fit neatly within the scope of one bureaucracy, we get duplication.
I'd predict that 10 years from now the Virginia Hemp Growers Association will have formed and will be lobbying for a simplification and consolidation of paperwork requirements.
