Freedom of Information Act Guide, May 2004
Exemption 9 of the FOIA covers "geological and geophysical information and
data, including maps, concerning wells." (1) This exemption has very rarely been
invoked or interpreted, (2) and its boundaries remain substantially undefined to this
day. As no court has examined Exemption 9 in any depth, it is still not clear exactly
what types of geological or geophysical information are protected from disclosure
under the exemption, or whether it was intended to apply to all types of "wells."
One court held twenty years ago that Exemption 9 applies only to "well
information of a technical or scientific nature," and not to general mineral exploration
data -- such as the location, depth, or number of exploration drill holes. (3) It is
significant that this court pointed to the legislative history of the FOIA -- specifically,
to evidence that Congress intended through Exemption 9 to protect the oil and gas
exploration and extraction industry from unfair competitive harm by "speculators" --
in support of its decision to order the release of generalized well data where a
competitive harm argument could not readily be supported. (4)
A recent decision, however, might give greater depth to Exemption 9. (5) In that
case, the court held that information related to the presence of groundwater --
including "ground water inventories, [water] well yield in gallons per minute, and the
thickness of the decomposed granite aquifer" -- was exempt from disclosure under
both Exemption 4 (6) and Exemption 9. (7) Though the court discussed the two
exemptions separately, with Exemption 9 receiving very little analysis, it emphasized
that "water is a precious, limited resource" and that release of well data would place
one party at a disadvantage in negotiations over its use. (8) Only two other decisions
have mentioned Exemption 9 with respect to the regulation of natural gas
producers; however, neither case discussed its scope or application in significant
A survey of all of the Exemption 9 cases decided to date suggests that its
present boundaries are defined neither by the type of well nor the type of
information. (10) In fact, what is clear from the Exemption 9 decisions thus far is that
courts have applied it to all types of wells and to various information about these
wells. (11) It also is reasonable to assume that both agencies and courts may apply
Exemption 9 to protect well data in other compelling circumstances, such as when
Exemption 9 protection is necessary to guard against an attack upon pooled natural
resources intended to cause harm to the public. (12)
