33 CFR § 385.33 - Revisions to models and analytical tools.

(a) In carrying out their responsibilities for implementing the Plan, the Corps of Engineers, the South Florida Water Management District, and other non-Federal sponsors shall rely on the best available science including models and other analytical tools for conducting analyses for the planning, design, construction, operation, and assessment of projects. The selection of models and analytical tools shall be done in consultation with the Department of the Interior, the Environmental Protection Agency, the Department of Commerce, the Miccosukee Tribe of Indians of Florida, the Seminole Tribe of Florida, the Florida Department of Environmental Protection, and other Federal, State, and local agencies.

(b) The Corps of Engineers, the South Florida Water Management District, and other non-Federal sponsors may, in consultation with the Department of the Interior, the Miccosukee Tribe of Indians of Florida, the Seminole Tribe of Florida, the Environmental Protection Agency, the Department of Commerce, the Florida Department of Environmental Protection, and other Federal, State, and local agencies, periodically revise models and analytical tools or develop new models and analytical tools as needed. As appropriate, RECOVER shall review the adequacy of system-wide simulation models and analytical tools used in the evaluation and assessment of projects, and shall propose improvements in system-wide models and analytical tools required for the evaluation and assessment tasks.

(c) The Corps of Engineers and the South Florida Water Management District shall determine on a case-by-case basis what documentation is appropriate for revisions to models and analytic tools, depending on the significance of the changes and their impacts to the Plan. Such changes may be treated as Minor Changes to the Plan, in accordance with § 385.32(c) where appropriate.
