Our DC staff did some research on this and unfortunately this answer is not going to make you happy.
The SBA determines HUB zones based on two criteria: unemployment data and percent of median household income. The SBA uses this data in a formula to determine eligibility or non-eligibility in every county in the United States (see this link for a current list: http://www.sba.gov/sites/default/files/files/NMClist.pdf). Unemployment data is collected on a monthly basis and the median income data is from the census (note that the recent addition of the American Community Survey causes this data to be adjusted every five years, not ten). The HUB eligible list is published on 1 October. Legislation had been passed a while ago to grandfather counties that lost certification to have an additional three years of eligibility or until the census occurred. Meriwether within the past three years had lost its HUB zone certification, but received the extension until the recent census. Thus, on 1 October Meriwether lost its HUB certification.
Currently there is legislation in the Senate discussing adding an additional three years to the extension, but it does not have much support in Congress.
There is no real appeal process, however a county may challenge the loss of certification with the SBA, but in Meriwether’s case, it would have to challenge each year’s data since it originally lost the HUB zone certification.
Unfortunately, there is no ability for Rep. Westmoreland to lend any assistance as the criteria for the designation of a HUB zone is data and formula driven.
I believe that Troup County, as long as their data does not change, is currently under a grandfathered extension and could lose its eligibility in October of 2013.
I apologize that we could not be of more help. Please let me know if you have any further questions.
Congressman Lynn Westmoreland (GA-03)
