On December 2, 2011, the La Cuna de Aztlan Sacred Sites Protection Circle Advisory Committee (“La Cuna”) filed an appeal from determinations issued to it on September 15, 2011 and November 28, 2011, by the Department of Energy’s (DOE) Loan Guarantee Program Office LGPO). In each determination, LGPO responded to a request for documents that La Cuna submitted under the Freedom of Information Act (FOIA), 5 U.S.C. § 552, as implemented by the DOE in 10 C.F.R. Part 1004. In response to the La Cuna’s FOIA request, LGPO identified and released a number of responsive documents, but withheld portions of the documents pursuant to FOIA Exemption 4. This appeal, if granted, would require LGPO to release the withheld information to La Cuna.
