MO SB413

Requires Missouri's natural resources trustee to offset natural resource damage assessments against potentially responsible parties by crediting the past, current, and future economic and ecological value of any land or property rights donated to the state

Economic benefit calculations must include fees, revenues, indirect benefits, patron spending, and economic multiplier effects on the geographic region, household income, and jobs

Ecological benefit calculations must use full past, present, and future ecological values (including National Contingency Plan values) rather than assessed property value

Allows potentially responsible parties to carry forward excess benefit credits to offset future natural resource damage assessments if donated property values exceed current damages owed

Prohibits the state natural resources trustee from transferring authority to assess or recover natural resource damages to any federal or other trustee
