6 U.S. Code § 1162 - Railroad carrier assessments and plans
Not later than 9 months after the date of issuance of the regulations under subsection (a), the vulnerability assessments and security plans required by such regulations for railroad carriers assigned to a high-risk tier shall be completed and submitted to the Secretary for review and approval.
The Secretary shall provide in a timely manner to the appropriate employees of a railroad carrier, as designated by the railroad carrier, threat information that is relevant to the carrier when preparing and submitting a vulnerability assessment and security plan, including an assessment of the most likely methods that could be used by terrorists to exploit weaknesses in railroad security.
The Secretary shall require that the individual serving as the security coordinator identified in paragraph (1)(A) is a citizen of the United States. The Secretary may waive this requirement with respect to an individual if the Secretary determines that it is appropriate to do so based on a background check of the individual and a review of the consolidated terrorist watchlist.
The Secretary shall ensure that the security plans developed by railroad carriers under this section are consistent with the risk assessment and National Strategy for Railroad Transportation Security developed under section 1161 of this title.
The Secretary may require railroad carriers, during the period before the deadline established under subsection (c), to submit a security plan under subsection (e) to implement any necessary interim security measures essential to providing adequate security of the railroad carrier’s system. An interim plan required under this subsection will be superseded by a plan required under subsection (e).
The Secretary may request, and a railroad carrier shall provide, information necessary for the Secretary to assign a railroad carrier to the appropriate tier under this subsection.
Not later than 60 days after the date a railroad carrier is assigned to a tier under this subsection, the Secretary shall notify the railroad carrier of the tier to which it is assigned and the reasons for such assignment.
At least one of the tiers established by the Secretary under this subsection shall be designated a tier for high-risk railroad carriers.
Nothing in this section shall be construed as authorizing the withholding of any information from Congress.
In response to a petition by a railroad carrier or at the discretion of the Secretary, the Secretary may determine that existing procedures, protocols, and standards meet all or part of the requirements of this section, including regulations issued under subsection (a), regarding vulnerability assessments and security plans.
Upon review and written determination by the Secretary that existing procedures, protocols, or standards of a railroad carrier satisfy the requirements of this section, the railroad carrier may elect to comply with those procedures, protocols, or standards instead of the requirements of this section.
If the Secretary determines that the existing procedures, protocols, or standards of a railroad carrier satisfy only part of the requirements of this section, the Secretary may accept such submission, but shall require submission by the railroad carrier of any additional information relevant to the vulnerability assessment and security plan of the railroad carrier to ensure that the remaining requirements of this section are fulfilled.
If the Secretary determines that particular existing procedures, protocols, or standards of a railroad carrier under this subsection do not satisfy the requirements of this section, the Secretary shall provide to the railroad carrier a written notification that includes an explanation of the determination.
Not later than 3 years after the date on which a vulnerability assessment or security plan required to be submitted to the Secretary under subsection (c) is approved, and at least once every 5 years thereafter (or on such a schedule as the Secretary may establish by regulation), a railroad carrier who submitted a vulnerability assessment and security plan and who is still assigned to the high-risk tier must also submit to the Secretary an evaluation of the adequacy of the vulnerability assessment and security plan that includes a description of any material changes made to the vulnerability assessment or security plan.
The Secretary may permit under this section the development and implementation of coordinated vulnerability assessments and security plans to the extent that a railroad carrier shares facilities with, or is colocated with, other transportation entities or providers that are required to develop vulnerability assessments and security plans under Federal law.
In carrying out this section, the Secretary shall consult with railroad carriers, nonprofit employee labor organizations representation railroad employees, and public safety and law enforcement officials.
 So in original. The word “to” probably should not appear.
