Why Wells?: Exploring the Freedom of Information Act's Ninth Exemption

Yesterday in my administrative law class, we discussed the Freedom of Information Act (FOIA) (5 U.S.C. §552). There is a lot in that act, but for purposes of this post, I am focusing on §552(b), the subsection of the act that exempts certain information from FOIA's requirement that governmental agencies provide information to parties' requests. Specifically, I am focusing on the ninth exemption to FOIA's requirements, which exempts "geological and geophysical information and data, including maps, concerning wells" from FOIA's disclosure requirements.

Other exemptions to FOIA allow the government to retain information that pertains to trade secrets, national security, or private information about agency personnel. Those exemptions make sense to me, but in light of those exemptions, I was led to wonder, "why wells?"

After some searching, I found the Department of Justice Guide to the Freedom of Information Act, which explains the breadth of the subsection nine exemption. In doing so, the guide illustrates the lack of cases that address the exemption.

I decided to look through the few cases that discuss the ninth exemption, and I found that they outlined an evolution in courts' interpretation of FOIA's ninth exemption. I explore this evolution after the jump.
