"This Protected Critical Infrastructure Information (PCII) Program Procedures Manual (Manual) provides guidance governing PCII and the PCII Program as established by Section 214 of the Critical Infrastructure Information Act of 2002 (CII Act) and Section 29.(b)(4) of the implementing Regulation(Regulation). Terms and acronyms used herein are defined in Appendix 2, Definitions. This revised Manual reflects the evolution of the PCII Program as an information sharing tool, the operational experience the PCII Program Office gained over the last 3 years, and the issuance of the Regulation in September 2006 that amended the interim rule under which the PCII Program had been operating. The Secretary of Homeland Security designated the Under Secretary of the National Protection and Programs Directorate as the senior DHS official responsible for the direction and administration of the PCII Program and the PCII Program Manager (PM), appointed by the Under Secretary, administers the PCII Program's daily operations. PCII is a category of Sensitive but Unclassified (SBU) information that is afforded protections from disclosure under the Freedom of Information Act (FOIA) and similar State and local disclosure laws and use in civil litigation or for regulatory purposes. The PCII Program is unique because it provides a method for critical infrastructure owners to submit information voluntarily to the Federal government that the government would not otherwise have access to. Once information is submitted and the PCII Program has validated it as PCII, Federal, State, and local government entities can use the information to protect the Nation's critical infrastructure."
