Section 310.23 - Defense Threat Reduction Agency (DTRA) exemptions(a)Exemption for classified material. All systems of records maintained by the Defense Threat Reduction Agency shall be exempt under section (k)(1) of 5 U.S.C. 552a , to the extent that the systems contain any information properly classified under E.O. 12598 and that is required by that E.O. to be kept secret in the interest of national defense or foreign policy. This exemption is applicable to parts of all systems of records including those not otherwise specifically designated for exemptions herein which contain isolated items of properly classified information.(1)System identifier and name. HDTRA 007, Security Operations. (i)Exemption. Portions of this system of records may be exempt from the provisions of 5 U.S.C. 552a(c)(3), (d)(1) through (d)(4), (e)(1), (e)(4)(G), (H), (I), and (f) .(ii)Authority.5 U.S.C. 552a(k)(5) .(iii)Reasons.(A) From subsection (c)(3) because it will enable DTRA to safeguard certain investigations and relay law enforcement information without compromise of the information, and protect the identities of confidential sources who might not otherwise come forward and who have furnished information under an express promise that the sources' identity would be held in confidence (or prior to the effective date of the Act, under an implied promise.)(B) From subsection (d)(1) through (d)(4) and (f) because providing access to records of a civil investigation and the right to contest the contents of those records and force changes to be made to the information contained therein would seriously interfere with, and thwart the orderly and unbiased conduct of security investigations. Providing access rights normally afforded under the Privacy Act would provide the subject with valuable information that would allow interference with or compromise of witnesses or render witnesses reluctant to cooperate; lead to suppression, alteration, or destruction of evidence; and result in the secreting of or other disposition of assets that would make them difficult or impossible to reach in order to satisfy any Government claim growing out of the investigation or proceeding.(C) From subsection (e)(1), (e)(4)(G), (H), (I) because it will provide protection against notification of investigatory material including certain reciprocal investigations and counterintelligence information, which might alert a subject to the fact that an investigation of that individual is taking place, and the disclosure of which would weaken the on-going investigation, reveal investigatory techniques, and place confidential informants in jeopardy who furnished information; under an express promise that the sources' identity would be held in confidence (or prior to the effective date of the Act, under an implied promise.)(2)System identifier and name. HDTRA 011, Inspector General Investigation Files. (i)Exemption. Portions of this system of records may be exempt from the provisions of 5 U.S.C. 552a(c)(3); (d)(1) through (4); (e)(1); (e)(4)(G), (H), and (I); and (f) .(ii)Authority.5 U.S.C. 552a(k)(2) .(iii)Reasons.(A) From subsection (c)(3) because it will enable DTRA to conduct certain investigations and relay law enforcement information without compromise of the information, protection of investigative techniques and efforts employed, and identities of confidential sources who might not otherwise come forward and who furnished information under an express promise that the sources' identity would be held in confidence (or prior to the effective date of the Act, under an implied promise.)(B) From subsection (d)(1) through (d)(4) and (f) because providing access to records of a civil investigation and the right to contest the contents of those records and force changes to be made to the information contained therein would seriously interfere with and thwart the orderly and unbiased conduct of the investigation and impede case preparation. Providing access rights normally afforded under the Privacy Act would provide the subject with valuable information that would allow interference with or compromise of witnesses or render witnesses reluctant to cooperate; lead to suppression, alteration, or destruction of evidence; and result in the secreting of or other disposition of assets that would make them difficult or impossible to reach in order to satisfy any Government claim growing out of the investigation or proceeding.(C) From subsection (e)(1), (e)(4)(G), (H), and (I) because it will provide protection against notification of investigatory material including certain reciprocal investigations and counterintelligence information, which might alert a subject to the fact that an investigation of that individual is taking place, and the disclosure of which would weaken the on-going investigation, reveal investigatory techniques, and place confidential informants in jeopardy who furnished information under an express promise that the sources' identity would be held in confidence (or prior to the effective date of the Act, under an implied promise).84 FR 14730, Apr. 11, 2019, as amended at 88 FR 42236, June 30, 2023 84 FR 14730, 5/13/2019; 88 FR 42236, 9/8/2023
