Sec. 227.12  Insoluble wastes.

    (a) Solid wastes consisting of inert natural minerals or materials 
compatible with the ocean environment may be generally approved for 
ocean dumping provided they are insoluble above the applicable trace or 
limiting permissible concentrations and are rapidly and completely 
settleable, and they are of a particle size and density that they would 
be deposited or rapidly dispersed without damage to benthic, demersal, 
or pelagic biota.
    (b) Persistent inert synthetic or natural materials which may float 
or remain in suspension in the ocean as prohibited in paragraph (d) of 
Sec. 227.5 may be dumped in the ocean only when they have been processed 
in such a fashion that they will sink to the bottom and remain in place.
