The Department of Homeland Security Transportation Security Administration (DHS TSA) has released the "Pipeline Security Guidelines" (Guidelines). Accompanying the Guidelines is a Supplement providing protective measures at various threat levels. The Guidelines are available for wide distribution, while the Supplement has been designated by TSA as Sensitive Security Information (SSI) and is held to information protection criteria and penalties associated with SSI. As such, the Supplement should be shared ONLY with those individuals with a "need to know". Should the operator require access to the Supplement, it is password protected. Please contact Kimberly Denbow, kdenbow@aga.org or the TSA Pipeline Security Division for the password.
