# §148.310. Seed cake.

- (a) This part does not apply to solvent-extracted rape seed meal, pellets, soya bean meal, cotton seed meal, or sunflower seed meal that—
  - (1) Contains a maximum of 4 percent vegetable oil and a maximum of 15 percent vegetable oil and moisture combined; and
  - (2) **As far as practical, is free from flammable solvent.**
- (b) This part does not apply to mechanically expelled citrus pulp pellets containing not more than 2.5 percent oil and a maximum of 14 percent oil and moisture combined.
- (c) Before loading, the seed cake must be aged per the instructions of the shipper.
- (d) Before loading, the shipper must give the master or person in charge of a barge a certificate from a competent testing laboratory stating the oil and moisture content of the seed cake.
- (e) The seed cake must be kept as dry as practical at all times.
- (f) If the seed cake is solvent-extracted, it must be—
  - (1) As free as practical from flammable solvent; and
  - (2) **Stowed in a mechanically ventilated hold.**
- (g) For a voyage with a planned duration greater than 5 days, the vessel must be equipped with facilities for introducing carbon dioxide or another inert gas into the hold.
- (h) Temperature readings of the seed cake must be taken at least once in every 24-hour period. If the temperature exceeds 55 °C (131 °F) and continues to increase, ventilation to the cargo hold must be discontinued. If heating continues after ventilation has been discontinued, carbon dioxide or the inert gas required under [paragraph (g)](#g) of this section must be introduced into the hold. If the seed cake is solvent-extracted, the use of inert gas must not be introduced until fire is apparent, to avoid the possibility of igniting the solvent vapors by the generation of static electricity.
- (i) Seed cake must be carried under the terms of a Special Permit issued by the Commandant (CG-ENG-5) per [subpart B](/cfr/46/subpartB.md) of this part if—
  - (1) The oil was mechanically expelled; and
  - (2) It contains more than 10 percent vegetable oil or more than 20 percent vegetable oil and moisture combined.
