The Transportation Security Administration (TSA) will issue a rulemaking document to respond to comments received on the interim final rule (IFR) issued May 18, 2004. In the IFR, published jointly with the Department of Transportation (DOT), Office of the Secretary in May 2004, TSA revised its Sensitive Security Information (SSI) regulations to expand the 2002 regulatory framework governing information generally related to aviation security to cover information related to security in maritime transportation, consistent with the security framework required by the U.S. Coast Guard's regulations implementing the Maritime Transportation Security Act (MTSA). This expansion was the main theme of the IFR. However, the IFR also continued TSA's 2002 regulations coverage for vulnerability assessments and, with some changes, certain other SSI for all modes. TSA and DOT issued a technical amendment to the IFR in January 2005 to address provisions of the regulations that inadvertently restricted sharing of SSI. Specifically, the amendment removed the limiting words "aviation or maritime" from 49 CFR 15.11 and 49 CFR 1520.11 in order to clearly permit the sharing of vulnerability assessments and other documents properly designated as SSI with covered persons who meet the need-to-know requirements regardless of mode of transportation.
