The Secretary shall establish a National List of approved and prohibited substances that shall be included in the standards for organic production and handling established under this chapter in order for such products to be sold or labeled as organically produced under this chapter.
The list established under subsection (a) shall contain an itemization, by specific use or application, of each synthetic substance permitted under subsection (c)(1) or each natural substance prohibited under subsection (c)(2).
The National List established by the Secretary shall be based upon a proposed national list or proposed amendments to the National List developed by the National Organic Standards Board.
The Secretary may not include exemptions for the use of specific synthetic substances in the National List other than those exemptions contained in the Proposed National List or Proposed Amendments to the National List.
In no instance shall the National List include any substance, the presence of which in food has been prohibited by Federal regulatory action.
Before establishing the National List or before making any amendments to the National List, the Secretary shall publish the Proposed National List or any Proposed Amendments to the National List in the Federal Register and seek public comment on such proposals. The Secretary shall include in such Notice any changes to such proposed list or amendments recommended by the Secretary.
After evaluating all comments received concerning the Proposed National List or Proposed Amendments to the National List, the Secretary shall publish the final National List in the Federal Register, along with a discussion of comments received.
The Secretary may develop emergency procedures for designating agricultural products that are commercially unavailable in organic form for placement on the National List for a period of time not to exceed 12 months.
No exemption or prohibition contained in the National List shall be valid unless the National Organic Standards Board has reviewed such exemption or prohibition as provided in this section within 5 years of such exemption or prohibition being adopted or reviewed and the Secretary has renewed such exemption or prohibition.
