            (2) State coordination.--The Secretary shall consult with 
        State geological surveys and other relevant entities to ensure, 
        to the maximum extent practicable, the usefulness and success 
        of the assessment.
    (d) Opportunity for Review and Comment.--During the period 
beginning on the date that is 270 days after the date of enactment of 
this Act and ending not less than 45 days, and not more than 90 days, 
after the commencement of the assessment, the Secretary shall provide 
the heads of stakeholder Federal agencies, the heads of State land 
management agencies, industry stakeholders, and the public with an 
opportunity to review and comment on the proposed methodology developed 
under subsection (a).
    (e) Independent Verification.--During the period described in 
subsection (d), the Secretary shall convene a committee of subject 
matter experts composed of representatives of Federal agencies, 
institutions of higher education, nongovernmental organizations, State 
organizations, industry, and international geoscience organizations to 
conduct a review of the methodology for capacity and risk estimation 
required to carry out this section.
    (f) Final Publication.--Not later than 90 days after the period 
described in subsection (d), the Secretary shall--
            (1) publish in the Federal Register a description of the
