The Centers for Disease Control and Prevention (CDC) provides guidance on the Freedom of Information Act (FOIA) exemptions, which specify categories of information protected from disclosure. Exemption 1 covers national security related to national defense or foreign relations, while Exemption 2 addresses internal agency personnel rules and practices. This exemption is divided into Low 2 for trivial matters and High 2 where disclosure could undermine agency regulations.
Exemption 3 permits withholding information explicitly prohibited from release by another federal statute. Exemption 4 protects trade secrets and commercial or financial information. Records that are predecisional and part of the decision-making process, such as inter-agency memoranda or attorney-client communications, fall under Exemption 5.
Exemption 6 protects personal privacy, allowing the withholding of documents if disclosure would constitute a clearly unwarranted invasion of privacy. Exemption 7 safeguards records compiled for law enforcement purposes, including identities of confidential sources and ongoing investigations. Exemption 8 relates to reports on the regulation of financial institutions, and Exemption 9 pertains to geological and geophysical data about wells, including maps.
The CDC's resource helps users understand FOIA and the applicable exemptions, including guidance on submitting and tracking FOIA requests.
