On April 5, 2017, Tim Hadley (Appellant) filed an Appeal from a Freedom of Information Act (FOIA) determination issued by the Department of Energy’s (DOE) Office of Public Information (OPI) (FOIA Request No. HQ-2016-01577-F). In that determination, OPI responded to a request for information filed under the FOIA, 5 U.S.C. § 552, as implemented by DOE in 10 C.F.R. Part 1004. OPI released nine documents but redacted portions of those documents under Exemption 4 of the FOIA. This Appeal, if granted, would release the information withheld under Exemption 4.
