For the three forms of solids that are listed in Sec. 355.15(a)(1) through (3), use these instructions to determine the quantity of extremely hazardous substance present:
(a) Solid in powdered form with a particle size less than 100 microns. Multiply the weight percent of solid with a particle size less than 100 microns in a particular container by the total weight of solid in the container.
(b) Solid in solution. Multiply the weight percent of the non-reactive solid in solution in a particular container by the total weight of solution in that container. Then multiply by 0.2.
Note to paragraph (b):
This reduction in quantity must not be used to determine the amount present at one-time at a facility for reporting under 40 CFR 370.10.
(c) Solid in molten form. Multiply the weight of the non-reactive solid in molten form by 0.3.
Note to paragraph (c):
This reduction in quantity must not be used to determine the amount present at one-time at a facility for reporting under 40 CFR 370.10. [73 FR 65462, Nov. 3, 2008, as amended at 77 FR 16688, Mar. 22, 2012]
